Since our canary value address is obtained without accessing memory (as opposed to pre-v7 code that will obtain it from a literal pool), it is unlikely (although not guaranteed) that the compiler will spill the canary value in the same way, so let's just disable this improvement when building with GCC9+.

(1UL << 64) is an overflow and breaks the algorithm. Subtracting 1 is a better guess for the initial value of m anyway and that's what also done in int_sqrt() implicitly [*]. [*] Note how int_sqrt() uses __fls() with two underscores, which already returns the proper raw bit number. In contrast, int_sqrt64() used fls64(), and that returns bit numbers illogically starting at 1, because of error handling for the "no bits set" case. Will points out that he bug probably is due to a copy-and-paste error from the regular int_sqrt() case.

This has the desirable effect of ensuring that all 'unsafe' accesses have been range-checked, without having to pick through all of the callsites to verify whether the appropriate checking has been made. However, the consolidated range check does not inhibit speculation, so it is still up to the caller to ensure that they are not susceptible to any speculative side-channel attacks for user addresses that ultimately fail the access_ok() check. This is an oversight, so use __uaccess_begin_nospec() to ensure that speculation is inhibited until the access_ok() check has passed.

Redirecting to a sit0 through __bpf_redirect_no_mac pulls the mac length, even though skb->data already is at skb->network_header. bpf_prog_test_run_skb has already pulled it as LWT_XMIT !is_l2. Update the offset calculation to pull only if skb->data differs from skb->network_header, which is not true in this case. The test itself can be run only from commit 1cf1cae963c2 ("bpf: introduce BPF_PROG_TEST_RUN command"), but the same type of packets with skb at network header could already be built from lwt xmit hooks, so this fix is more relevant to that commit. Also set the mac header on redirect from LWT_XMIT, as even after this change to __bpf_redirect_no_mac that field is expected to be set, but is not yet in ip_finish_output2.

This worked fine if a single PF existed that registered one callback for the tunnel netdev of interest. However, if multiple PFs are in place then the 2nd PF tries to register with the same tunnel netdev identifier. This leads to EEXIST errors and/or incorrect cb deletions. Prevent this conflict by using the rpriv pointer as the identifier for netdev indirect block cb registry, allowing each PF to register a unique callback per tunnel netdev. For block cb registry, the same PF may register multiple cbs to the same block if using TC shared blocks. Instead of the rpriv, use the pointer to the allocated indr_priv data as the identifier here. This means that there can be a unique block callback for each PF/tunnel netdev combo.

Fortunately the padding octets are usually zero's, which don't affect checksum. However, we have a switch which pads non-zero octets, this causes kernel hardware checksum fault repeatedly. Prior to: commit '88078d98d1bb ("net: pskb_trim_rcsum() and CHECKSUM_COMPLETE ...")' skb checksum was forced to be CHECKSUM_NONE when padding is detected. After it, we need to keep skb->csum updated, like what we do for RXFCS. However, fixing up CHECKSUM_COMPLETE requires to verify and parse IP headers, it is not worthy the effort as the packets are so small that CHECKSUM_COMPLETE can't save anything.

Digging deeper: The files were imported from the iproute2 repository with the GPL V2 or later boiler plate text in commit b66e907cfee2 ("tools: bpftool: copy JSON writer from iproute2 repository") Looking at the iproute2 repository at git://git.kernel.org/pub/scm/network/iproute2/iproute2.git the following commit is the equivivalent: commit d9d8c839 ("json_writer: add SPDX Identifier (GPL-2/BSD-2)") That commit explicitly removes the boiler plate and relicenses the code uner GPL-2.0-only and BSD-2-Clause. As Steven wrote the original code and also the relicensing commit, it's assumed that the relicensing was intended to do exaclty that. Just the kernel side update failed to remove the boiler plate.

In particular one such case is index masking to prevent out of bounds access under speculative execution due to missing the map's unpriv_array/index_mask field propagation. Fix this such that the verifier is generating the correct code for inlined lookups in case of unpriviledged use.

This implicit action sets a dummy FID to the packet and is used as part of a design for trapping unmatched flows in OVS. While this implicit FID setting action is supposed to be a NOP when a redirect action is added, in Spectrum-2 the FID record is consulted as the dummy FID index is an 802.1D FID index and the packet is dropped instead of being redirected. Set the dummy FID index value to be within 802.1Q range. This satisfies both Spectrum-1 which ignores the FID and Spectrum-2 which identifies it as an 802.1Q FID and will then follow the redirect action.

The device then tries to post a CQE (completion queue element) that contains various metadata (e.g., ingress port) about the packet to a CQ (completion queue). In case the device managed to consume a WQE, but did not manage to post the corresponding CQE, it will get stuck. This unlikely situation can be triggered due to the scheme the driver is currently using to process CQEs. The driver will consume up to 512 CQEs at a time and after processing each corresponding WQE it will ring the RDQ's doorbell, letting the device know that a new WQE was posted for it to consume. Only after processing all the CQEs (up to 512), the driver will ring the CQ's doorbell, letting the device know that new ones can be posted. Fix this by having the driver ring the CQ's doorbell for every processed CQE, but before ringing the RDQ's doorbell. This guarantees that whenever we post a new WQE, there is a corresponding CQE available. Copy the currently processed CQE to prevent the device from overwriting it with a new CQE after ringing the doorbell. Note that the driver still arms the CQ only after processing all the pending CQEs, so that interrupts for this CQ will only be delivered after the driver finished its processing. Before commit 8404f6f2e8ed ("mlxsw: pci: Allow to use CQEs of version 1 and version 2") the issue was virtually impossible to trigger since the number of CQEs was twice the number of WQEs and the number of CQEs processed at a time was equal to the number of available WQEs.

Delaying iputs means we are potentially delaying the eviction of an inode and it's respective space. The cleaner thread only gets woken up every 30 seconds, or when we require space. If there are a lot of inodes that need to be deleted we could induce a serious amount of latency while we wait for these inodes to be evicted. So instead wakeup the cleaner if it's not already awake to process any new delayed iputs we add to the list. If we suddenly need space we will less likely be backed up behind a bunch of inodes that are waiting to be deleted, and we could possibly free space before we need to get into the flushing logic which will save us some latency.

So before we decide to commit the transaction for ENOPSC reasons, run the delayed iputs so that any potential space is free'd up.

The driver mistakenly uses the mdio port address as the MDIO command request device address instead of the MDIO command request port address. Additionally, the driver does not properly check for and create a clause 45 MDIO command. Check the supplied MDIO register to determine if the request is a clause 45 operation (MII_ADDR_C45). For a clause 45 operation, extract the device address and register number from the supplied MDIO register and use them to set the MDIO command request device address and register number fields. For a clause 22 operation, the MDIO request device address is set to zero and the MDIO command request register number is set to the supplied MDIO register. In either case, the supplied MDIO port address is used as the MDIO command request port address.

Because the ethernet header length has been considered in is_skb_forwardable(including dev->hard_header_len length). To reproduce the issue: 1, add 2 ports on linux bridge br using following commands: $ brctl addbr br $ brctl addif br eth0 $ brctl addif br eth1 2, the MTU of eth0 and eth1 is 1500 3, send a packet(Data 1480, UDP 8, IP 20, Ethernet 14, VLAN 4) from eth0 to eth1 So the expect result is packet larger than 1500 cannot pass through eth0 and eth1. But currently, the packet passes through success, it means eth1's MTU limit doesn't take effect.

But we try to log GIOVA when device IOTLB is enabled. This is wrong and may lead to missing data after migration. To solve this issue, when logging with device IOTLB enabled, we will: 1) reuse the device IOTLB translation result of GIOVA->HVA mapping to get HVA, for writable descriptor, get HVA through iovec. For used ring update, translate its GIOVA to HVA 2) traverse the GPA->HVA mapping to get the possible GPA and log through GPA. Pay attention this reverse mapping is not guaranteed to be unique, so we should log each possible GPA in this case. This fix the failure of scp to guest during migration. In -next, we will probably support passing GIOVA->GPA instead of GIOVA->HVA.

This problem is more generally related to device with variable hard header length. To avoid a too intrusive patch in the current release, a (ugly) workaround is proposed in this patch. It has to be cleaned up in net-next.

But the check always returns true since the record type is assigned 0. And this breaks console ramoops by showing current console log instead of previous log on warm reset and hard reset (actually hard reset should not be showing any logs). Fix this by having persistent ram zone type check instead of record type check. Tested this on SDM845 MTP and dragonboard 410c. Reproducing this issue is simple as below: 1. Trigger hard reset and mount pstore. Will see console-ramoops record in the mounted location which is the current log. 2. Trigger warm reset and mount pstore. Will see the current console-ramoops record instead of previous record.

Fix this by: (1) Getting an extra ref for an asynchronous call for the call itself to hold. This makes sure the call doesn't evaporate on us accidentally and will allow the call to be retained by the caller in a future patch. The ref is released on leaving afs_make_call() or afs_wait_for_call_to_complete(). (2) In the event of an error from rxrpc_kernel_send_data(): (a) Don't set the call state to AFS_CALL_COMPLETE until *after* the call has been aborted and ended. This prevents afs_deliver_to_call() from doing anything with any notifications it gets. (b) Explicitly end the call immediately to prevent further callbacks. (c) Cancel any queued async_work and wait for the work if it's executing. This allows us to be sure the race won't recur when we change the state. We put the work queue's ref on the call if we managed to cancel it. (d) Put the call's ref that we got in (1). This belongs to us as long as the call is in state AFS_CALL_CL_REQUESTING.

However, the string passed to PCI setup is actually a temporary copy allocated in static __initdata memory. After init, once the memory is freed, it is no longer valid to reference this pointer. This bug was noticed in v5.0-rc1 after a change in commit c5eb1190074c ("PCI / PM: Allow runtime PM without callback functions") caused pci_disable_acs_redir() to be called during shutdown which manifested as an unable to handle kernel paging request at: RIP: 0010:pci_enable_acs+0x3f/0x1e0 Call Trace: pci_restore_state.part.44+0x159/0x3c0 pci_restore_standard_config+0x33/0x40 pci_pm_runtime_resume+0x2b/0xd0 ? pci_restore_standard_config+0x40/0x40 __rpm_callback+0xbc/0x1b0 rpm_callback+0x1f/0x70 ? pci_restore_standard_config+0x40/0x40 rpm_resume+0x4f9/0x710 ? pci_conf1_read+0xb6/0xf0 ? pci_conf1_write+0xb2/0xe0 __pm_runtime_resume+0x47/0x70 pci_device_shutdown+0x1e/0x60 device_shutdown+0x14a/0x1f0 kernel_restart+0xe/0x50 __do_sys_reboot+0x1ee/0x210 ? __fput+0x144/0x1d0 do_writev+0x5e/0xf0 ? do_writev+0x5e/0xf0 do_syscall_64+0x48/0xf0 entry_SYSCALL_64_after_hwframe+0x44/0xa9 It was also likely possible to trigger this bug when hotplugging PCI devices.

Commit e07db28eea38 ("kbuild: fix single target build for external module") turned it into a build error because the 'prepare' target is now executed but the 'prepare0' target is missing for the external module build. External module on arm/arm64 with CONFIG_STACKPROTECTOR_PER_TASK is also broken in the same way. Move 'PHONY += prepare0' to the common place. GNU Make is fine with missing rule for phony targets.

Looking into the code, it looks like skb protocol is not always fetched for each iteration of the filters. But, as demonstrated by Martin, TC actions could modify skb->protocol, for example act_vlan, this means we have to refetch skb protocol in each iteration, rather than using the one we fetch in the beginning of the loop. This bug is _not_ introduced by commit 3b3ae880266d ("net: sched: consolidate tc_classify{,_compat}"), technically, if act_vlan is the only action that modifies skb protocol, then it is commit c7e2b9689ef8 ("sched: introduce vlan action") which introduced this bug.

But we don't consider that, then number of the allocated irq vector may be same with sum of io_queues[HCTX_TYPE_DEFAULT] and io_queues[HCTX_TYPE_READ], this way is obviously wrong, and finally breaks nvme_pci_map_queues(), and warning from pci_irq_get_affinity() is triggered. IRQ queues should cover admin queues, this patch makes this point explicitely in nvme_calc_io_queues(). We got severl boot failure internal report on aarch64, so please consider to fix it in v4.20.

During its execution, kaslr_early_init() also randomizes the base of the module region and of the linear mapping of DRAM, and sets two variables accordingly. However, since these variables are assigned with the caches on, they may get lost during the cache maintenance that occurs when unmapping and remapping the kernel, so ensure that these values are cleaned to the PoC.

A kernel built without CONFIG_RANDOMIZE_BASE, instead checks the cpufeature static-key. This leaves a gap where CONFIG_RANDOMIZE_BASE was enabled, no kaslr seed was provided, but kpti was forced on using the cmdline option. When the decision is made late, kpti_install_ng_mappings() will re-write the page tables, but arm64_kernel_use_ng_mappings()'s value does not change as it only tests the cpufeature static-key if CONFIG_RANDOMIZE_BASE is disabled. This function influences PROT_DEFAULT via PTE_MAYBE_NG, and causes pgattr_change_is_safe() to catch nG->G transitions when the unchanged PROT_DEFAULT is used as part of PAGE_KERNEL_RO: [ 1.942255] alternatives: patching kernel code [ 1.998288] ------------[ cut here ]------------ [ 2.000693] kernel BUG at arch/arm64/mm/mmu.c:165!

This caused systematic failures in the following TDC test case: 7a88 - Add tunnel_key action with cookie parameter Avoid matching zero values of TCA_TUNNEL_KEY_ENC_DST_PORT to let the test pass again.

Miller commit e122d845a01ece2ddd28b2f125ef2db66b8b627a Author: David Howells Date: Thu Jan 10 16:59:13 2019 +0000 Revert "rxrpc: Allow failed client calls to be retried" The changes introduced to allow rxrpc calls to be retried creates an issue when it comes to refcounting afs_call structs. The problem is that when rxrpc_send_data() queues the last packet for an asynchronous call, the following sequence can occur: (1) The notify_end_tx callback is invoked which causes the state in the afs_call to be changed from AFS_CALL_CL_REQUESTING or AFS_CALL_SV_REPLYING. (2) afs_deliver_to_call() can then process event notifications from rxrpc on the async_work queue. (3) Delivery of events, such as an abort from the server, can cause the afs_call state to be changed to AFS_CALL_COMPLETE on async_work. (4) For an asynchronous call, afs_process_async_call() notes that the call is complete and tried to clean up all the refs on async_work. (5) rxrpc_send_data() might return the amount of data transferred (success) or an error - which could in turn reflect a local error or a received error. Synchronising the clean up after rxrpc_kernel_send_data() returns an error with the asynchronous cleanup is then tricky to get right. Mostly revert commit c038a58ccfd6704d4d7d60ed3d6a0fca13cf13a4. The two API functions the original commit added aren't currently used. This makes rxrpc_kernel_send_data() always return successfully if it queued the data it was given. Note that this doesn't affect synchronous calls since their Rx notification function merely pokes a wait queue and does not refcounting. The asynchronous call notification function *has* to do refcounting and pass a ref over the work item to avoid the need to sync the workqueue in call cleanup.

The interaction between CAKE's GSO splitting and the parent qdisc's notion of its own queue length could cause queue stalls. While investigating the report, I also noticed that several qdiscs would dereference the skb pointer after dequeue, which is potentially problematic since the GSO splitting code also frees the original skb. See the individual patches in the series for details. ==================== Signed-off-by: David S.

This is done by checking if the qlen is exactly 1 after enqueue. However, if GSO splitting is enabled in the child qdisc, a single packet can result in a qlen longer than 1. This means the activation check fails, leading to a stalled queue. Fix this by checking if the queue is empty *before* enqueue, and running the activation logic if this was the case.

However, if a device supports MSI-X but not MSI and a caller requests @min_vecs that can't be satisfied by MSI-X, we previously returned -EINVAL (from the failed attempt to enable MSI), not -ENOSPC. When -ENOSPC is returned, callers may reduce the number IRQs they request and try again. Most callers can use the @min_vecs and @max_vecs parameters to avoid this retry loop, but that doesn't work when using IRQ affinity "nr_sets" because rebalancing the sets is driver-specific. This return value bug has been present since pci_alloc_irq_vectors() was added in v4.10 by aff171641d18 ("PCI: Provide sensible IRQ vector alloc/free routines"), but it wasn't an issue because @min_vecs/@max_vecs removed the need for callers to iteratively reduce the number of IRQs requested and retry the allocation, so they didn't need to distinguish -ENOSPC from -EINVAL. In v5.0, 6da4b3ab9a6e ("genirq/affinity: Add support for allocating interrupt sets") added IRQ sets to the interface, which reintroduced the need to check for -ENOSPC and possibly reduce the number of IRQs requested and retry the allocation.

Wysocki Date: Wed Jan 9 00:34:37 2019 +0100 ACPI: EC: Look for ECDT EC after calling acpi_load_tables() Some systems have had functional issues since commit 5a8361f7ecce (ACPICA: Integrate package handling with module-level code) that, among other things, changed the initial values of the acpi_gbl_group_module_level_code and acpi_gbl_parse_table_as_term_list global flags in ACPICA which implicitly caused acpi_ec_ecdt_probe() to be called before acpi_load_tables() on the vast majority of platforms. Namely, before commit 5a8361f7ecce, acpi_load_tables() was called from acpi_early_init() if acpi_gbl_parse_table_as_term_list was FALSE and acpi_gbl_group_module_level_code was TRUE, which almost always was the case as FALSE and TRUE were their initial values, respectively. The acpi_gbl_parse_table_as_term_list value would be changed to TRUE for a couple of platforms in acpi_quirks_dmi_table[], but it remained FALSE in the vast majority of cases. After commit 5a8361f7ecce, the initial values of the two flags have been reversed, so in effect acpi_load_tables() has not been called from acpi_early_init() any more. That, in turn, affects acpi_ec_ecdt_probe() which is invoked before acpi_load_tables() now and it is not possible to evaluate the _REG method for the EC address space handler installed by it. That effectively causes the EC address space to be inaccessible to AML on platforms with an ECDT matching the EC device definition in the DSDT and functional problems ensue in there. Because the default behavior before commit 5a8361f7ecce was to call acpi_ec_ecdt_probe() after acpi_load_tables(), it should be safe to do that again. Moreover, the EC address space handler installed by acpi_ec_ecdt_probe() is only needed for AML to be able to access the EC address space and the only AML that can run during acpi_load_tables() is module-level code which only is allowed to access address spaces with default handlers (memory, I/O and PCI config space). For this reason, move the acpi_ec_ecdt_probe() invocation back to acpi_bus_init(), from where it was taken away by commit d737f333b211 (ACPI: probe ECDT before loading AML tables regardless of module-level code flag), and put it after the invocation of acpi_load_tables() to restore the original code ordering from before commit 5a8361f7ecce.

In response to events in the netdev and inetaddr notification chains 2. When a network namespace is being dismantled In both cases only routes associated with a dead nexthop group are flushed. However, a nexthop group will only be marked as dead in case it is populated with actual nexthops using a nexthop device. This is not the case when the route in question is an error route (e.g., 'blackhole', 'unreachable'). Therefore, when a network namespace is being dismantled such routes are not flushed and leaked [1]. To reproduce: # ip netns add blue # ip -n blue route add unreachable 192.0.2.0/24 # ip netns del blue Fix this by not skipping error routes that are not marked with RTNH_F_DEAD when flushing the routing tables. To prevent the flushing of such routes in case #1, add a parameter to fib_table_flush() that indicates if the table is flushed as part of namespace dismantle or not. Note that this problem does not exist in IPv6 since error routes are associated with the loopback device.

Remote and port also have augmented reference counts, so drop them on each iteration and at the end of the function, respectively. Remote is only used for the address it contains, not for the contents of that address, so the reference count can be dropped immediately.

I traced it down to the client underrunning the GSS sequence number window -- NFS servers are required to drop the RPC with the low sequence number, and also drop the connection to signal that an RPC was dropped. Bisected to commit 918f3c1fe83c ("SUNRPC: Improve latency for interactive tasks"). I've got a one-line workaround for this issue, which is easy to backport to v4.20 while a more permanent solution is being derived. Essentially, tk_owner-based sorting is disabled for RPCs that carry a GSS sequence number. Fixes: 918f3c1fe83c ("SUNRPC: Improve latency for interactive ...

Since clang does not support asm goto, at 4.17, Commit b1ae32dbab50 ("x86/cpufeature: Guard asm_volatile_goto usage for BPF compilation") worked around the issue by permitting an alternative implementation without asm goto for clang. At 5.0, more asm goto usages appeared.

And it is also not practical to make changes for each call site. This patch workarounded the asm goto issue by redefining the macro like below: #define asm_volatile_goto(x...) asm volatile("invalid use of asm_volatile_goto") If asm_volatile_goto is not used by bpf programs, which is typically the case, nothing bad will happen. If asm_volatile_goto is used by bpf programs, which is incorrect, the compiler will issue an error since "invalid use of asm_volatile_goto" is not valid assembly codes. With this patch, all bpf programs under samples/bpf can pass compilation. Note that bpf programs under tools/testing/selftests/bpf/ compiled fine as they do not access kernel internal headers.

It leads to a situation where umem is not assigned to any Tx/Rx queue of a netdevice, without notifying the stack about an error. This affects both XDP_SKB and XDP_DRV modes - in case of XDP_DRV_ZC, queue index is checked by the driver. This patch fixes xsk code, so that in both XDP_SKB and XDP_DRV mode of AF_XDP, an error is returned when requested queue index exceedes an existing maximum.

Then the thread proceeds to free the filter, even though the listener struct file has a reference to it. To fix this, on the failure path let's set the private data to null, so we know in ->release() to ignore the filter.

Instead of having two entries for each syscall number, one for the regular entry point and one for the compat entry point, we now have separate tables for regular and compat entry points. This inadvertently broke syscall tracing (CONFIG_FTRACE_SYSCALLS), because our implementation of arch_syscall_addr() knew about the layout of the table (it did nr * 2).

Previously when VRR is enabled atomic check will grab the connector state for every atomic update. This has to lock the connector in order to do so. The locking is bad enough by itself for performance, but it gets worse with what we do just below that - add all the planes for the CRTC to the commit. This prevents the cursor fast path from working - there's more than one plane now. With state->allow_modeset = true on top of this, it also adds and removes all the planes from the DC context triggering a full (very slow) update in DC.

The reason is that IPS_HELPER_BIT is only set when using explicit CT target. However, in the case that a device enables conntrack helper via command "echo 1 > /proc/sys/net/netfilter/nf_conntrack_helper", the status of IPS_HELPER_BIT will not present any change, and consequently it loses the checking ability in the context.

This causes warnings or build failures (where -Werror applies) such as the following: arch/mips/generic/init.c: error: -ffunction-sections disabled; it makes profiling impossible This used to be taken into account by the ordering of calls to cc-option from within the top-level Makefile, which was introduced by commit 90ad4052e85c ("kbuild: avoid conflict between -ffunction-sections and -pg on gcc-4.7"). Unfortunately this was broken when the CONFIG_LD_DEAD_CODE_DATA_ELIMINATION cc-option check was moved to Kconfig in commit e85d1d65cd8a ("kbuild: test dead code/data elimination support in Kconfig"), because the flags used by this check no longer include -pg. Fix this by not allowing CONFIG_LD_DEAD_CODE_DATA_ELIMINATION to be enabled at the same time as ftrace/CONFIG_FUNCTION_TRACER when building using GCC 4.7 or older.

Due to the way it is implemented, it would have to be updated after 5.0, to keep the resulting versions unique. Linus Torvalds argued: "Do we actually need this? I'd rather let it bitrot, and just let it return random versions. It will just start again at 2.4.60, won't it? Anybody who uses UNAME26 for a 5.x kernel might as well think it's still 4.x. The user space is so old that it can't possibly care about differences between 4.x and 5.x, can it?

To safely support mapping the allocations to userspace major architectures like x86 and arm have always zeroed allocations from dma_alloc_coherent, but a couple other architectures were missing that zeroing either always or in corner cases. Then later we grew anothe dma_zalloc_coherent interface to explicitly request zeroing, but that just added __GFP_ZERO to the allocation flags, which for some allocators that didn't end up using the page allocator ended up being a no-op and still not zeroing the allocations. So for this merge window I fixed up all remaining architectures to zero the memory in dma_alloc_coherent, and made dma_zalloc_coherent a no-op wrapper around dma_alloc_coherent, which fixes all of the above issues. dma_zalloc_coherent is now pointless and can go away, and Luis helped me writing a cocchinelle script and patch series to kill it, which I think we should apply now just after -rc1 to finally settle these issue" * tag 'remove-dma_zalloc_coherent-5.0' of git://git.infradead.org/users/hch/dma-mapping: dma-mapping: remove dma_zalloc_coherent() cross-tree: phase out dma_zalloc_coherent() on headers cross-tree: phase out dma_zalloc_coherent() commit 2f960bd0564081ff85d2eea54890b0d2356934f8 Merge: 8d008e64a2ebe 6ef982dec7eda Author: David S.

This results into driver being able to get larger number of MSI-X vectors than actual online CPUs. Driver then uses pci_alloc_irq_vectors_affinity() to assign 1:1 mapping and affinity for each MSI-x vector to CPUs. When the command is submitted using MSI-x vector, assigned to offline CPU, it results in an ABTS and system hang. This hang is result of a driver not being able to process interrupt on a vector assigned to an Off-line CPUs This patch fixes this issue by setting irq_offset value for the blk_mq_pci_map_queues() to use only those CPUs which has CPU mask affinity assigned and are online. By using the irq_offset value, driver will allow online cpumask to decide which vectors are used in blk_mq_pci_map_queues().

For example: struct foo { int stuff; void *entry[]; }; instance = kzalloc(sizeof(struct foo) + sizeof(void *) * count, GFP_KERNEL); Instead of leaving these open-coded and prone to type mistakes, we can now use the new struct_size() helper: instance = kzalloc(struct_size(instance, entry, count), GFP_KERNEL); This code was detected with the help of Coccinelle.

The first patch adds an exit code for UMH process. This provides an opportunity to cleanup members of the umh_info to modules which use the UMH. In order to identify UMH processes, a new flag PF_UMH is added. The second patch makes the bpfilter_umh use UMH cleanup callback. The third patch adds re-start routine for the bpfilter_umh. The bpfilter_umh does not re-start after error occurred. because there is no re-start routine in the module. The fourth patch ensures that the bpfilter.ko module will not removed while it's being used. The bpfilter.ko is not protected by locks or module reference counter. Therefore that can be removed while module is being used. In order to protect that, mutex is used. The first and second patch are preparation patches for the third and fourth patch.

But the do_exit() does not release members of the umh_info. hence module which uses UMH needs own code to detect whether UMH process is terminated or not. But this implementation needs extra code for checking the status of UMH process. it eventually makes the code more complex. The new PF_UMH flag is added and it is used to identify UMH processes.

For some corner cases the timers are always working only for the ringbuffer's and full queue's newest cmd. That's to say the timer won't be fired even if one cmd has been stuck for a very long time and the deadline is reached. This fix will keep the cmd/qfull timers to be pended for the oldest cmd in ringbuffer and full queue, and will update them with the next cmd's deadline only when the old cmd's deadline is reached or removed from the ringbuffer and full queue.

This inconsistency causes one bug in vhost vsock driver. The scenarios is: 0. A hash table (vhost_vsock_hash) is used to map an CID to a vsock object. And hash_min() is used to compute the hash key. hash_min() is defined as: (sizeof(val) <= 4 ? hash_32(val, bits) : hash_long(val, bits)). That means the hash algorithm has dependency on the size of macro argument 'val'. 0. In function vhost_vsock_set_cid(), a 64bit CID is passed to hash_min() to compute the hash key when inserting a vsock object into the hash table. 0. In function vhost_vsock_get(), a 32bit CID is passed to hash_min() to compute the hash key when looking up a vsock for an CID. Because the different size of the CID, hash_min() returns different hash key, thus fails to look up the vsock object for an CID. To fix this bug, we keep CID as u64 in the IOCTLs and virtio message headers, but explicitly convert u64 to u32 when deal with the hash table and vsock core.

Looking at the SATA PHY initialization routine, there is a comment about "vendor specific" registers. Two registers are mentioned. They are not initialized there in the firmware because they are AHCI related, while the firmware at this location does only PHY configuration. The solution to avoid doing such initialization is relying on U-Boot. While this work at boot time, U-Boot is definitely not going to run during a resume after suspending to RAM. Two possible solutions were considered: * Fixing the firmware. * Fixing the kernel driver. The first solution would take ages to propagate, while the second solution is easy to implement as the driver as been a little bit reworked to prepare for such platform configuration. Hence, this patch adds an Armada 3700 configuration function to set these two registers both at boot time (in the probe) and after a suspend (in the resume path).

Commit 15d3ce7b63bd ("ata: ahci_mvebu: add support for Armada 3700 variant") introduced Armada 3700 support. As opposed to Armada 38x SoCs, the 3700 variants do not have to configure mbus and the regret option. This patch took care of avoiding such configuration when not needed in the probe function, but failed to do the same in the resume path. While doing so looks harmless by experience, let's clean the driver logic and avoid doing this useless configuration with Armada 3700 SoCs. Because the logic is very similar between these two places, it has been decided to factorize this code and put it in a "Armada 38x configuration function". This function is part of a new (per-compatible) platform data structure, so that the addition of such configuration function for Armada 3700 will be eased.

Correct the situation by adding a call to phy_set_mode() before phy_power_on(). PHYs should also be handled at suspend/resume time. For this, call ahci_platform_enable/disable_phys() at suspend/resume_host() time. These calls are guarded by a HFLAG (AHCI_HFLAG_SUSPEND_PHYS) that the user of the libahci driver must set manually in hpriv->flags at probe time. This is to avoid breaking users that have not been tested with this change.

This results in the "cd-inverted" property being evaluated twice, which effectively makes it a no-op: - first in drivers/gpio/gpiolib-of.c (of_xlate_and_get_gpiod_flags) when setting up the CD GPIO - then again in drivers/mmc/core/slot-gpio.c (mmc_gpio_get_cd) when reading the CD GPIO value at runtime On boards which are using device-tree with the "cd-inverted" property being set any inserted card are not detected anymore. This is due to the MMC core treating the CD GPIO with the wrong polarity. Disable "override_cd_active_level" for the card detection GPIO which is parsed using mmc_of_parse. This fixes SD card detection on the boards which are currently using the "cd-inverted" device-tree property (tested on Meson8b Odroid-C1 and Meson8b EC-100). This does not remove the CD GPIO inversion logic from the MMC core because there's at least one driver (sdhci-pci-core for Intel BayTrail based boards) which still passes "override_cd_active_level = true" to mmc_gpiod_request_cd(). Due to lack of hardware for testing this is left untouched. In the future the GPIO inversion logic for both, card and read-only detection can be removed once no driver is using it anymore.

This missed the case where the node name is passed to offb_init_palette_hacks(). This results in a NULL ptr dereference in strncmp and breaks any system except ones using bootx with no display node. Fix this by making offb_init_palette_hacks() use the OF node pointer and use of_node_name_prefix() helper function instead for node name comparisons. This helps in moving all OF node name accesses to helper functions in preparation to remove struct device_node.name pointer.

The demultiplex thread receives the response, wakes up the thread and the latter collects credits from the response buffer and add them to the server structure on the client. This approach is not accurate, because it may race with reconnect events in the demultiplex thread which resets the number of credits. Fix this by moving credit processing to new mid callbacks that collect credits granted by the server from the response in the demultiplex thread.

For example: struct foo { int stuff; void *entry[]; }; instance = devm_kzalloc(dev, sizeof(struct foo) + sizeof(void *) * count, GFP_KERNEL); Instead of leaving these open-coded and prone to type mistakes, we can now use the new struct_size() helper: instance = devm_kzalloc(dev, struct_size(instance, entry, count), GFP_KERNEL); This code was detected with the help of Coccinelle.

The commit contained a bug where the incorrect parameters could be passed to function btf_bitfield_seq_show(). The bits_offset parameter in the function expects a value less than 8. Instead, the member offset in the structure is passed. The below is btf_bitfield_seq_show() func signature: void btf_bitfield_seq_show(void *data, u8 bits_offset, u8 nr_bits, struct seq_file *m) both bits_offset and nr_bits are u8 type. If the bitfield member offset is greater than 256, incorrect value will be printed. This patch fixed the issue by calculating correct proper data offset and bits_offset similar to non kind_flag case.

Do the same for ebtables. The syzbot, by using setsockopt(EBT_SO_SET_ENTRIES), was able to OOM the whole system from a restricted memcg, a potential DoS. By accounting the ebt_table_info, the memory used for ebt_table_info can be contained within the memcg of the allocating process. However the lifetime of ebt_table_info is independent of the allocating process and is tied to the network namespace. So, the oom-killer will not be able to relieve the memory pressure due to ebt_table_info memory. The memory for ebt_table_info is allocated through vmalloc. Currently vmalloc does not handle the oom-killed allocating process correctly and one large allocation can bypass memcg limit enforcement. So, with this patch, at least the small allocations will be contained. For large allocations, we need to fix vmalloc.

However this does not apply on the initial timeout of SYN-data (active Fast Open). Therefore an active IPv6 Fast Open connection may incur one second RTO penalty to take on a new path after the second SYN retransmission uses a new flow label. This patch removes this undesirable behavior so Fast Open changes the flow label just like the regular connections. This also helps avoid falsely disabling Fast Open on the sender which triggers after two consecutive SYN timeouts on Fast Open.

Given that most CPU implementations do not require kpti, this mainly impacts KASLR builds where kpti is forcefully enabled. However, in these situations we know early on that non-global mappings are required and can avoid the use of global mappings from the beginning. The only gotcha is Cavium erratum #27456, which we must detect based on the MIDR value of the boot CPU.

Silva Date: Wed Jan 9 17:23:54 2019 +0000 afs: Use struct_size() in kzalloc() One of the more common cases of allocation size calculations is finding the size of a structure that has a zero-sized array at the end, along with memory for some number of elements for that array. For example: struct foo { int stuff; void *entry[]; }; instance = kzalloc(sizeof(struct foo) + sizeof(void *) * count, GFP_KERNEL); Instead of leaving these open-coded and prone to type mistakes, we can now use the new struct_size() helper: instance = kzalloc(struct_size(instance, entry, count), GFP_KERNEL); This code was detected with the help of Coccinelle.

We use btrfs_find_device() with dev uuid and fs uuid set to NULL, and only dependent on @devid to find the real device. For seed devices, we call clone_fs_devices() in open_seed_devices() to allow us search seed devices directly. However clone_fs_devices() just populates devices with devid and dev uuid, without populating other essential members, like disk_total_bytes. This makes any device returned by btrfs_find_device(fs_info, devid, NULL, NULL) is just a dummy, with 0 disk_total_bytes, and any dev extents on the seed device will not pass the device boundary check. [FIX] This patch will try to verify the device returned by btrfs_find_device() and if it's a dummy then re-search in seed devices.

Miller commit 9f51c05dc41a6d69423e3d03d18eb7ab22f9ec19 Author: Wen Yang Date: Wed Dec 5 10:35:50 2018 +0800 pvcalls-front: Avoid get_free_pages(GFP_KERNEL) under spinlock The problem is that we call this with a spin lock held. The call tree is: pvcalls_front_accept() holds bedata->socket_lock. -> create_active() -> __get_free_pages() uses GFP_KERNEL The create_active() function is only called from pvcalls_front_accept() with a spin_lock held, The allocation is not allowed to sleep and GFP_KERNEL is not sufficient. This issue was detected by using the Coccinelle software. v2: Add a function doing the allocations which is called outside the lock and passing the allocated data to create_active(). v3: Use the matching deallocators i.e., free_page() and free_pages(), respectively. v4: It would be better to pre-populate map (struct sock_mapping), rather than introducing one more new struct. v5: Since allocating the data outside of this call it should also be freed outside, when create_active() fails. Move kzalloc(sizeof(*map2), GFP_ATOMIC) outside spinlock and use GFP_KERNEL instead. v6: Drop the superfluous calls.

However, it fails to consider the case where the rtattr's payload is longer than 4 bytes but not 4-byte aligned, and where the key ends before the next 4-byte aligned boundary. In this case, 'keylen -= RTA_ALIGN(rta->rta_len);' underflows to a value near UINT_MAX. This causes a buffer overread and crash during crypto_ahash_setkey(). Fix it by restricting the rtattr payload to the expected size.

To better understand which pixclock values are considered valid and how driver should handle these values, I briefly examined few existing fbdev drivers and documentation in Documentation/fb/. And it looks like there are no strict rules on that and actual behaviour varies: * some drivers treat (pixclock == 0) as "use defaults" (uvesafb.c); * some treat (pixclock == 0) as invalid value which leads to -EINVAL (clps711x-fb.c); * some pass converted pixclock value to hardware (uvesafb.c); * some are trying to find nearest value from predefined table (vga16fb.c, video_gx.c). Given this, I believe that it should be safe to just ignore this value if changing is not supported. It seems that any portable fbdev application which was not written only for one specific device working under one specific kernel version should not rely on any particular behaviour of pixclock anyway. However, while enabling SDL1 applications to work out of the box when there is no /etc/fb.modes with valid settings, this change affects the video mode choosing logic in SDL. Depending on current screen resolution, contents of /etc/fb.modes and resolution requested by application, this may lead to user-visible difference (not always): image will be displayed in a right way, but it will be aligned to the left instead of center. There is no "right behaviour" here as well, as emulated fbdev, opposing to old fbdev drivers, simply ignores any requsts of video mode changes with resolutions smaller than current. The easiest way to reproduce this problem is to install sdl-sopwith[2], remove /etc/fb.modes file if it exists, and then try to run sopwith from console without X. At least in Fedora 29, sopwith may be simply installed from standard repositories.

Prior to commit db05c48197759 ("drm: fb-helper: Reject all pixel format changing requests"), there was an unintentional workaround for this that existed for more than a decade. First in device-specific DRM drivers, then here in drm_fb_helper.c. Previous code containing this workaround just ignores pixel format fields from userspace code. Not a good thing either, as this way, driver may silently use pixel format different from what client actually requested, and this in turn will lead to displaying garbage on the screen. I think that returning EINVAL to userspace in this particular case is the right option, so I decided to left code from problematic commit untouched instead of just reverting it entirely. Here is the steps required to reproduce this problem exactly: 1) Compile fceux[2] with SDL 1.2.15 and without GTK or OpenGL support. SDL should be compiled with fbdev support (which is on by default). 2) Create /etc/fb.modes with following contents (values seems not used, and just required to trigger problematic code in SDL): mode "test" geometry 1 1 1 1 1 timings 1 1 1 1 1 1 1 endmode 3) Create ~/.fceux/fceux.cfg with following contents: SDL.Hotkeys.Quit = 27 SDL.DoubleBuffering = 1 4) Ensure that screen resolution is at least 1280x960 (e.g. append "video=Virtual-1:1280x960-32" to the kernel cmdline for qemu/QXL). 5) Try to run fceux on VT with some ROM file[3]: # ./fceux color_test.nes [1] SDL 1.2.15 source code, src/video/fbcon/SDL_fbvideo.c, FB_SetVideoMode() [2] http://www.fceux.com [3] Example ROM: https://github.com/bokuweb/rustynes/blob/master/roms/color_test.nes Reported-by: saahriktu Suggested-by: saahriktu Cc: stable@vger.kernel.org Fixes: db05c48197759 ("drm: fb-helper: Reject all pixel format changing requests") Signed-off-by: Ivan Mironov [danvet: Delete misleading comment.] Signed-off-by: Daniel Vetter Link: https://patchwork.freedesktop.org/patch/msgid/20190108072353.28078-2-mironov.ivan@gmail.com Link: https://patchwork.freedesktop.org/patch/msgid/20190108072353.28078-2-mironov.ivan@gmail.com commit 5db470e229e22b7eda6e23b5566e532c96fb5bc3 Author: Jaegeuk Kim Date: Wed Jan 9 19:17:14 2019 -0800 loop: drop caches if offset or block_size are changed If we don't drop caches used in old offset or block_size, we can get old data from new offset/block_size, which gives unexpected data to user.

If that happens we can deadlock because creating a pending block group needs to update the free space tree, and if any of the updates tries to modify the same extent buffer that we are COWing, we end up in a deadlock since we try to write lock twice the same extent buffer. So fix this by skipping pending block group creation if we are COWing an extent buffer from the free space tree. This is a case missed by commit 5ce555578e091 ("Btrfs: fix deadlock when writing out free space caches"). Bugzilla: https://bugzilla.kernel.org/show_bug.cgi?id=202173 Fixes: 5ce555578e091 ("Btrfs: fix deadlock when writing out free space caches") CC: stable@vger.kernel.org # 4.18+ Signed-off-by: Filipe Manana Reviewed-by: David Sterba Signed-off-by: David Sterba commit d8b5524242108cb7d28c9b8b9aded7c1edd0e8a8 Author: Filipe Manana Date: Tue Jan 8 11:43:07 2019 +0000 Btrfs: fix race between reflink/dedupe and relocation The recent rework that makes btrfs' remap_file_range operation use the generic helper generic_remap_file_range_prep() introduced a race between relocation and reflinking (for both cloning and deduplication) the file extents between the source and destination inodes. This happens because we no longer lock the source range anymore, and we do not lock it anymore because we wait for direct IO writes and writeback to complete early on the code path right after locking the inodes, which guarantees no other file operations interfere with the reflinking. However there is one exception which is relocation, since it replaces the byte number of file extents items in the fs tree after locking the range the file extent items represent. This is a problem because after finding each file extent to clone in the fs tree, the reflink process copies the file extent item into a local buffer, releases the search path, inserts new file extent items in the destination range and then increments the reference count for the extent mentioned in the file extent item that it previously copied to the buffer. If right after copying the file extent item into the buffer and releasing the path the relocation process updates the file extent item to point to the new extent, the reflink process ends up creating a delayed reference to increment the reference count of the old extent, for which the relocation process already created a delayed reference to drop it. This results in failure to run delayed references because we will attempt to increment the count of a reference that was already dropped.

This happens because we now wait for writeback to complete before doing the truncation of the eof block, while previously we did the truncation and then waited for writeback to complete. This leads to a race between writeback of the truncated block and cloning the file extents in the source range, because we copy each file extent item we find in the fs root into a buffer, then release the path and then increment the reference count for the extent referred in that file extent item we copied, which can no longer exist if writeback of the truncated eof block completes after we copied the file extent item into the buffer and before we incremented the reference count. This is illustrated by the following diagram: CPU 1 CPU 2 btrfs_clone_files() btrfs_cont_expand() btrfs_truncate_block() --> zeroes part of the page containg eof, marking it for delalloc btrfs_clone() --> finds extent item covering eof, points to extent at bytenr X --> copies it into a local buffer --> releases path writeback starts btrfs_finish_ordered_io() insert_reserved_file_extent() __btrfs_drop_extents() --> creates delayed reference to drop the extent at bytenr X --> starts transaction --> creates delayed reference to increment extent at bytenr X When this race is hit the running transaction ends up getting aborted with an -EIO error and a trace like the following is produced: [ 4382.553858] WARNING: CPU: 2 PID: 3648 at fs/btrfs/extent-tree.c:1552 lookup_inline_extent_backref+0x4f4/0x650 [btrfs] (...)

However, in the slow path, it does so while specifying the current and max frequencies in different units, hence resulting in a broken freq_scale factor.

Unfortunately that version doesn't actually prevent compiler from optimizing out the variable. Fix up by moving the macro out from compiler-gcc.h to compiler.h. Compilers without incline asm support will keep working since it's protected by an ifdef. Also fix up comments to match reality since we are no longer overriding any macros. Build-tested with gcc and clang.

DP1_SRCCTRL is configured to a magic number. This patch changes the configuration as follows: Configure DP0_SRCCTRL by using tc_srcctrl() which provides the correct value. DP1_SRCCTRL needs two bits to be set to the same value as DP0_SRCCTRL: SSCG and BW27. All other bits can be zero.

In the isci driver, scsi_host_set_prot() is called after scsi_add_host() so the command size gets calculated to be smaller than it needs to be. Eventually, scsi_mq_init_request() locates the 'prot_sdb' after the command assuming it was sized correctly and a buffer overrun may occur. However, seeing blk_mq_alloc_rqs() rounds up to the nearest cache line size, the mistake can go unnoticed. The bug was noticed after the struct request size was reduced by commit 9d037ad707ed ("block: remove req->timeout_list") Which likely reduced the allocated space for the request by an entire cache line, enough that the overflow could be hit and it caused a panic, on boot, at: RIP: 0010:t10_pi_complete+0x77/0x1c0 Call Trace: sd_done+0xf5/0x340 scsi_finish_command+0xc3/0x120 blk_done_softirq+0x83/0xb0 __do_softirq+0xa1/0x2e6 irq_exit+0xbc/0xd0 call_function_single_interrupt+0xf/0x20 sd_done() would call scsi_prot_sg_count() which reads the number of entities in 'prot_sdb', but seeing 'prot_sdb' is located after the end of the allocated space it reads a garbage number and erroneously calls t10_pi_complete(). To prevent this, the calls to scsi_host_set_prot() are moved into isci_host_alloc() before the call to scsi_add_host(). Out of caution, also move the similar call to scsi_host_set_guard().

For example, After above inconsistent status happens, IO request can be submitted to UFS device driver but required resource (like clock) is not resumed yet thus lead to warning as below call stack, WARN_ON(hba->clk_gating.state != CLKS_ON); ufshcd_queuecommand scsi_dispatch_cmd scsi_request_fn __blk_run_queue cfq_insert_request __elv_add_request blk_flush_plug_list blk_finish_plug jbd2_journal_commit_transaction kjournald2 We may see all behind IO requests hang because of no response from storage host or device and then soft lockup happens in system.

Nevertheless, the possibility exists and so it's best to avoid the problem. This patch flags a zone as needing a kswapd using the, surprisingly, unused zone flag field. The flag is read without the lock held to do the wakeup. It's possible that the flag setting context is not the same as the flag clearing context or for small races to occur. However, each race possibility is harmless and there is no visible degredation in fragmentation treatment.

There are a few issues with this approach. One is that krealloc callers can't rely on comparing the return value with the passed argument to check whether reallocation happened. Another is that if a caller knows that no reallocation happened, that it can access object memory through the old pointer, which leads to false positives. Look at nf_ct_ext_add() to see an example. Fix this by keeping the same tag if the memory don't actually gets reallocated during krealloc.

That in turn hits a memory limit reclaim and the memcg reclaim for legacy controller is waiting on the writeback but that is never going to finish because the writeback itself is waiting for the page locked in the #PF path. So this is essentially ABBA deadlock: lock_page(A) SetPageWriteback(A) unlock_page(A) lock_page(B) lock_page(B) pte_alloc_pne shrink_page_list wait_on_page_writeback(A) SetPageWriteback(B) unlock_page(B) # flush A, B to clear the writeback This accumulating of more pages to flush is used by several filesystems to generate a more optimal IO patterns. Waiting for the writeback in legacy memcg controller is a workaround for pre-mature OOM killer invocations because there is no dirty IO throttling available for the controller. There is no easy way around that unfortunately. Therefore fix this specific issue by pre-allocating the page table outside of the page lock. We have that handy infrastructure for that already so simply reuse the fault-around pattern which already does this. There are probably other hidden __GFP_ACCOUNT | GFP_KERNEL allocations from under a fs page locked but they should be really rare. I am not aware of a better solution unfortunately.

For example, once writeback limit budget is exausted, admin can see 0 from /sys/block/zramX/writeback_limit which is same semantic with disable writeback_limit at this moment. IOW, admin cannot tell that zero came from disable writeback limit or exausted writeback limit. To make the interface clear, let's sepatate enable of writeback limit to another knob - /sys/block/zram0/writeback_limit_enable * before: while true : # to re-enable writeback limit once previous one is used up echo 0 > /sys/block/zram0/writeback_limit echo $((200<<20)) > /sys/block/zram0/writeback_limit .. .. # used up the writeback limit budget * new # To enable writeback limit, from the beginning, admin should # enable it. echo $((200<<20)) > /sys/block/zram0/writeback_limit echo 1 > /sys/block/zram/0/writeback_limit_enable while true : echo $((200<<20)) > /sys/block/zram0/writeback_limit .. .. # used up the writeback limit budget It's much strightforward. 2. fix condition check idle/huge writeback mode check The mode in writeback_store is not bit opeartion any more so no need to use bit operations. Furthermore, current condition check is broken in that it does writeback every pages regardless of huge/idle. 3. clean up idle_store No need to use goto.

Currently, all DRM drivers supporting atomic modesetting will save the state that userspace had set before suspending, then attempt to restore that state on resume. This probably worked very well at one point, like many other things, until DP MST came into the picture. While it's easy to restore state on normal display connectors that were disconnected during suspend regardless of their state post-resume, this can't really be done with MST because of the fact that setting up a downstream sink requires performing sideband transactions between the source and the MST hub, sending out the ACT packets, etc. Because of this, there isn't really a guarantee that we can restore the atomic state we had before suspend once we've resumed. This sucks pretty bad, but so far I haven't run into any compositors that this actually causes serious issues with. Most compositors will notice the hotplug we send afterwards, and then reprobe state. Since nouveau and i915 also don't fail the suspend/resume process due to failing to restore the atomic state, let's make amdgpu match this behavior. Better to resume the GPU properly, then to stop the process half way because of a potentially unavoidable atomic commit failure. Eventually, we'll have a real fix for this problem on the DRM level. But we've got some more important low-hanging fruit to deal with first.

Currently, amdgpu just makes the mistake of ignoring the return code from drm_dp_mst_topology_mgr_resume() which means that if a topology was removed in suspend, amdgpu never notices and assumes it's still connected which leads to all sorts of problems. So, fix this by actually checking the rc from drm_dp_mst_topology_mgr_resume(). Also, reformat the rest of the function while we're at it to fix the over-indenting.

With multiple chains present, cb->args[0] is therefore updated after each chain's rules have been traversed. This though causes the final nf_tables_dump_rules() run (which should return an skb->len of zero since no rules are left to dump) to continue dumping rules for each but the first chain. Fix this by moving the cb->args[0] update to nf_tables_dump_rules(). With no final action to be performed anymore in __nf_tables_dump_rules(), drop 'out_unfinished' jump label and 'rc' variable - instead return the appropriate value directly.

The router block then drops the packets due to checksum error, as the test generates packets with zero checksum. When running the test on an emulator that is not as strict about checksum errors the test fails since packets are counted twice. Once by the emulated ASIC on its ingress filter and again by the kernel as the emulator does not perform checksum validation and allows the packets to be trapped by a matching host route. Fix this by changing the action to 'drop', which will prevent the packet from continuing further in the pipeline to the router block. For veth pairs this change is essentially a NOP given packets are only processed once (by the kernel).

This can result in a memory leak [1] when VXLAN and mlxsw ports are enslaved to the bridge: $ ip link set dev vxlan0 master br0 # No mlxsw ports are enslaved to 'br0', so mlxsw ignores the switchdev # notification and the bridge driver adds the VLAN on 'vxlan0' via the # 8021q driver $ bridge vlan add vid 10 dev vxlan0 pvid untagged # mlxsw port is enslaved to the bridge $ ip link set dev swp1 master br0 # mlxsw processes the switchdev notification and the 8021q driver is # skipped $ bridge vlan del vid 10 dev vxlan0 This results in 'struct vlan_info' and 'struct vlan_vid_info' being leaked, as they were allocated by the 8021q driver during VLAN addition, but never freed as the 8021q driver was skipped during deletion. Fix this by introducing a new VLAN private flag that indicates whether the VLAN was added on the port by switchdev or the 8021q driver. If the VLAN was added by the 8021q driver, then we make sure to delete it via the 8021q driver as well.

Taking the RTNL lock upon driver removal is useless since the driver first removes its ports and unregisters from notifiers so concurrent writes cannot happen at that time.

Technically, we could record the start_time anytime during fork(2). But this might lead to scenarios where a start_time is recorded long before a process becomes visible to user-space. For instance, with userfaultfd(2) and TLS, user-space can delay the execution of fork(2) for an indefinite amount of time (and will, if this causes network access, or similar). By recording the start_time late, it much closer reflects the point in time where the process becomes live and can be observed by other processes. Lastly, this makes it much harder for user-space to predict and control the start_time they get assigned. Previously, user-space could fork a process and stall it in copy_thread_tls() before its pid is allocated, but after its start_time is recorded. This can be misused to later-on cycle through PIDs and resume the stalled fork(2) yielding a process that has the same pid and start_time as a process that existed before. This can be used to circumvent security systems that identify processes by their pid+start_time combination. Even though user-space was always aware that start_time recording is flaky (but several projects are known to still rely on start_time-based identification), changing the start_time to be recorded late will help mitigate existing attacks and make it much harder for user-space to control the start_time a process gets assigned.

This causes the sg_init_table of clear_bam_transaction() in the driver's qcom_nandc_block_bad() to memset much more than what was initially allocated by alloc_bam_transaction(). This patch restores the old behavior by reallocating the shared bam transaction alloc_bam_transaction() after the chip was identified, but before mtd_device_parse_register() (which is an alias for mtd_device_register() - see panic) gets called. This fixes the corruption and the driver is working again.

The mti,cpu-interrupt-controller from irq-mips-cpu.c now handles the CPU interrupts and also the IPI interrupts which are used to communication between the CPUs in a SMP system. The generic interrupt code was already used before but the interrupt vectors were overwritten again when we called set_vi_handler() in the lantiq interrupt driver and we also provided our own plat_irq_dispatch() function which overwrote the weak generic implementation. Now the code uses the generic handler for the MIPS CPU interrupts including the IPI interrupts and registers a handler for the CPU interrupts which are handled by the lantiq ICU with irq_set_chained_handler() which was already called before. Calling the set_c0_status() function is also not needed any more because the generic MIPS CPU interrupt already activates the needed bits.

To have minimal possible size of flat kernel Image, we should have all non-loadable sections after loadable sections. Currently, execption table section (loadable section) is after BSS section (non-loadable section) in the RISC-V vmlinux.lds.S. This is not optimal for having minimal flat kernel Image size hence this patch makes BSS section as the last section in RISC-V vmlinux.lds.S. In addition, we make BSS section aligned to 16byte instead of PAGE aligned which further reduces flat kernel Image size by few KBs. The flat kernel Image size of Linux-4.20-rc4 using GCC 8.2.0 is 8819980 bytes with current RISC-V vmlinux.lds.S and it reduces to 7991740 bytes with this patch applied. In summary, this patch reduces Linux-4.20-rc4 flat kernel Image size by 809 KB.

The reset driver for the SoCFPGA platform needs to register early in order to be able bring online timers that needed early in the kernel bootup. We do not need this early reset driver for Stratix10, because on arm64, Linux does not need the timers are that in reset. Linux is able to run just fine with the internal armv8 timer. Thus, we use a new binding "altr,stratix10-rst-mgr" for the Stratix10 platform. The Stratix10 platform will continue to use the reset-simple platform driver, while the 32-bit platforms(Cyclone5/Arria5/Arria10) will use the early reset driver.

In combination with a configured checksum calculation where the result is stored relatively to the end of the data (e.g. cgw_csum_xor_rel) the tail of the skb (e.g. frag_list pointer in skb_shared_info) can be rewritten which finally can cause a system crash. Michael Kubecek suggested to drop frames that have a DLC exceeding the available space after the modification process and provided a patch that can handle CAN FD frames too. Within this patch we also limit the length for the checksum calculations to the maximum of Classic CAN data length (8). CAN frames that are dropped by these additional checks are counted with the CGW_DELETED counter which indicates misconfigurations in can-gw rules. This fixes CVE-2019-3701.

Miller commit f65e192af35058e5c82da9e90871b472d24912bc Author: Stephen Warren Date: Thu Jan 3 10:23:23 2019 -0700 net/mlx4: Get rid of page operation after dma_alloc_coherent This patch solves a crash at the time of mlx4 driver unload or system shutdown. The crash occurs because dma_alloc_coherent() returns one value in mlx4_alloc_icm_coherent(), but a different value is passed to dma_free_coherent() in mlx4_free_icm_coherent(). In turn this is because when allocated, that pointer is passed to sg_set_buf() to record it, then when freed it is re-calculated by calling lowmem_page_address(sg_page()) which returns a different value. Solve this by recording the value that dma_alloc_coherent() returns, and passing this to dma_free_coherent(). This patch is roughly equivalent to commit 378efe798ecf ("RDMA/hns: Get rid of page operation after dma_alloc_coherent").

For proper fuel-gauge and charger operation the TS current-source needs to be permanently on. But to read the GPADC we need to temporary switch the TS current-source to ondemand, so that the GPADC can use it, otherwise we will always read an all 0 value. The switching from on to on-ondemand is not necessary when the TS current-source is off (this happens on devices which do not have a TS). Prior to this commit there were 2 issues with our handling of the TS current-source switching: 1) We were writing hardcoded values to the ADC TS pin-ctrl register, overwriting various other unrelated bits. Specifically we were overwriting the current-source setting for the TS and GPIO0 pins, forcing it to 80ųA independent of its original setting. On a Chuwi Vi10 tablet this was causing us to get a too high adc value (due to a too high current-source) resulting in acpi_lpat_raw_to_temp() returning -ENOENT, resulting in: ACPI Error: AE_ERROR, Returned by Handler for [UserDefinedRegion] ACPI Error: Method parse/execution failed \_SB.SXP1._TMP, AE_ERROR This commit fixes this by using regmap_update_bits to change only the relevant bits. 2) At the end of intel_xpower_pmic_get_raw_temp() we were unconditionally enabling the TS current-source even on devices where the TS-pin is not used and the current-source thus was off on entry of the function. This commit fixes this by checking if the TS current-source is off when entering intel_xpower_pmic_get_raw_temp() and if so it is left as is.

The problem with that traditional semantic is that it exposes a lot of system cache state that it really probably shouldn't, and that users shouldn't really even care about. So let's try to avoid that information leak by simply changing the semantics to be that mincore() counts actual mapped pages, not pages that might be cheaply mapped if they were faulted (note the "might be" part of the old semantics: being in the cache doesn't actually guarantee that you can access them without IO anyway, since things like network filesystems may have to revalidate the cache before use). In many ways the old semantics were somewhat insane even aside from the information leak issue. From the very beginning (and that beginning is a long time ago: 2.3.52 was released in March 2000, I think), the code had a comment saying Later we can get more picky about what "in core" means precisely. and this is that "later". Admittedly it is much later than is really comfortable. NOTE! This is a real semantic change, and it is for example known to change the output of "fincore", since that program literally does a mmmap without populating it, and then doing "mincore()" on that mapping that doesn't actually have any pages in it. I'm hoping that nobody actually has any workflow that cares, and the info leak is real. We may have to do something different if it turns out that people have valid reasons to want the old semantics, and if we can limit the information leak sanely.

It turns out that the bug wasn't actually in that commit itself (which would have been surprising: it was mostly a no-op), but in how the addition of access_ok() to the strncpy_from_user() and strnlen_user() functions now triggered the case where those functions would test the access of the very last byte of the user address space. The string functions actually did that user range test before too, but they did it manually by just comparing against user_addr_max(). But with user_access_begin() doing the check (using "access_ok()"), it now exposed problems in the architecture implementations of that function. For example, on alpha, the access_ok() helper macro looked like this: #define __access_ok(addr, size) \ ((get_fs().seg & (addr | size | (addr+size))) == 0) and what it basically tests is of any of the high bits get set (the USER_DS masking value is 0xfffffc0000000000). And that's completely wrong for the "addr+size" check. Because it's off-by-one for the case where we check to the very end of the user address space, which is exactly what the strn*_user() functions do. Why? Because "addr+size" will be exactly the size of the address space, so trying to access the last byte of the user address space will fail the __access_ok() check, even though it shouldn't. As a result, the user string accessor functions failed consistently - because they literally don't know how long the string is going to be, and the max access is going to be that last byte of the user address space. Side note: that alpha macro is buggy for another reason too - it re-uses the arguments twice. And SH has another version of almost the exact same bug: #define __addr_ok(addr) \ ((unsigned long __force)(addr) < current_thread_info()->addr_limit.seg) so far so good: yes, a user address must be below the limit. But then: #define __access_ok(addr, size) \ (__addr_ok((addr) + (size))) is wrong with the exact same off-by-one case: the case when "addr+size" is exactly _equal_ to the limit is actually perfectly fine (think "one byte access at the last address of the user address space") The SH version is actually seriously buggy in another way: it doesn't actually check for overflow, even though it did copy the _comment_ that talks about overflow. So it turns out that both SH and alpha actually have completely buggy implementations of access_ok(), but they happened to work in practice (although the SH overflow one is a serious serious security bug, not that anybody likely cares about SH security). This fixes the problems by using a similar macro on both alpha and SH. It isn't trying to be clever, the end address is based on this logic: unsigned long __ao_end = __ao_a + __ao_b - !!__ao_b; which basically says "add start and length, and then subtract one unless the length was zero". We can't subtract one for a zero length, or we'd just hit an underflow instead. For a lot of access_ok() users the length is a constant, so this isn't actually as expensive as it initially looks.

This can be confusing to users, prompting a search as to why the parameter is invalid. To assist in that search, add a bit more information to the failure, additionally adding to the documentation that CONFIG_BLK_DEV_ZONED is needed for zoned=1.

Signed-off-by: Jens Axboe commit 8094c3ceb21ad93896fd4d238e8ba41911932eaf Author: Eric Biggers Date: Sun Jan 6 08:36:21 2019 -0500 fscrypt: add Adiantum support Add support for the Adiantum encryption mode to fscrypt. Adiantum is a tweakable, length-preserving encryption mode with security provably reducible to that of XChaCha12 and AES-256, subject to a security bound. It's also a true wide-block mode, unlike XTS. See the paper "Adiantum: length-preserving encryption for entry-level processors" (https://eprint.iacr.org/2018/720.pdf) for more details. Also see commit 059c2a4d8e16 ("crypto: adiantum - add Adiantum support"). On sufficiently long messages, Adiantum's bottlenecks are XChaCha12 and the NH hash function. These algorithms are fast even on processors without dedicated crypto instructions. Adiantum makes it feasible to enable storage encryption on low-end mobile devices that lack AES instructions; currently such devices are unencrypted. On ARM Cortex-A7, on 4096-byte messages Adiantum encryption is about 4 times faster than AES-256-XTS encryption; decryption is about 5 times faster. In fscrypt, Adiantum is suitable for encrypting both file contents and names. With filenames, it fixes a known weakness: when two filenames in a directory share a common prefix of >= 16 bytes, with CTS-CBC their encrypted filenames share a common prefix too, leaking information. Adiantum does not have this problem. Since Adiantum also accepts long tweaks (IVs), it's also safe to use the master key directly for Adiantum encryption rather than deriving per-file keys, provided that the per-file nonce is included in the IVs and the master key isn't used for any other encryption mode. This configuration saves memory and improves performance. A new fscrypt policy flag is added to allow users to opt-in to this configuration.

If arch does not have specific implementation of a mandatory header, Kbuild will let it fallback to the asm-generic one by automatically generating a wrapper. This will allow to drop lots of redundant generic-y defines. Previously, "mandatory" was used in the context of UAPI, but I guess this can be extended to kernel space ASM headers.

Prior to that commit, exported headers must be explicitly added to header-y. Now, all headers under the uapi/ directories are exported.

The jump label is controlled by HAVE_JUMP_LABEL, which is defined like this: #if defined(CC_HAVE_ASM_GOTO) && defined(CONFIG_JUMP_LABEL) # define HAVE_JUMP_LABEL #endif We can improve this by testing 'asm goto' support in Kconfig, then make JUMP_LABEL depend on CC_HAS_ASM_GOTO. Ugly #ifdef HAVE_JUMP_LABEL will go away, and CONFIG_JUMP_LABEL will match to the real kernel capability.

It might either be a byte value or taken to the power of two. On ARM it's actually the latter which leads to unnecessary large alignments of 16 bytes for 32 bit builds or 256 bytes for 64 bit builds. Fix this by switching to '.balign' instead which is consistent across all architectures.

When [::] is passed by user as destination, sys_sendmsg rewrites it with [::1] to be consistent with BSD (see "BSD'ism" comment in the code). This didn't work when cgroup-bpf was enabled though since the rewrite [::] -> [::1] happened before passing control to cgroup-bpf block where fl6.daddr was updated with passed by user sockaddr_in6.sin6_addr (that might or might not be changed by BPF program). That way if user passed [::] as dst IPv6 it was first rewritten with [::1] by original code from 876c7f41, but then rewritten back with [::] by cgroup-bpf block. It happened even when BPF_CGROUP_UDP6_SENDMSG program was not present (CONFIG_CGROUP_BPF=y was enough). The fix is to apply BSD'ism after cgroup-bpf block so that [::] is replaced with [::1] no matter where it came from: passed by user to sys_sendmsg or set by BPF_CGROUP_UDP6_SENDMSG program.

Long long ago, in commit 6175ddf06b61 ("x86: Clean up mem*io functions") Brian Gerst simplified the memory copies to and from iomem, since on x86, the instructions to access iomem are exactly the same as the regular instructions. That is technically true, and things worked, and nobody said anything. Besides, back then the regular memcpy was pretty simple and worked fine. Nobody noticed except for David Laight, that is. David has a testing a TLP monitor he was writing for an FPGA, and has been occasionally complaining about how memcpy_toio() writes things one byte at a time. Which is completely unacceptable from a performance standpoint, even if it happens to technically work. The reason it's writing one byte at a time is because while it's technically true that accesses to iomem are the same as accesses to regular memory on x86, the _granularity_ (and ordering) of accesses matter to iomem in ways that they don't matter to regular cached memory. In particular, when ERMS is set, we default to using "rep movsb" for larger memory copies. That is indeed perfectly fine for real memory, since the whole point is that the CPU is going to do cacheline optimizations and executes the memory copy efficiently for cached memory. With iomem? Not so much. With iomem, "rep movsb" will indeed work, but it will copy things one byte at a time. Slowly and ponderously. Now, originally, back in 2010 when commit 6175ddf06b61 was done, we didn't use ERMS, and this was much less noticeable. Our normal memcpy() was simpler in other ways too. Because in fact, it's not just about using the string instructions. Our memcpy() these days does things like "read and write overlapping values" to handle the last bytes of the copy. Again, for normal memory, overlapping accesses isn't an issue. For iomem? It can be. So this re-introduces the specialized memcpy_toio(), memcpy_fromio() and memset_io() functions. It doesn't particularly optimize them, but it tries to at least not be horrid, or do overlapping accesses. In fact, this uses the existing __inline_memcpy() function that we still had lying around that uses our very traditional "rep movsl" loop followed by movsw/movsb for the final bytes. Somebody may decide to try to improve on it, but if we've gone almost a decade with only one person really ever noticing and complaining, maybe it's not worth worrying about further, once it's not _completely_ broken?

For an example of the effect of this, this is the code generated for the unsafe_put_user(signo, &infop->si_signo, Efault); in the waitid() system call: movl %ecx,(%rbx) # signo, MEM[(struct __large_struct *)_2] It's just one single store instruction, along with generating an exception table entry pointing to the Efault label case in case that instruction faults. Before, we would generate this: xorl %edx, %edx movl %ecx,(%rbx) # signo, MEM[(struct __large_struct *)_3] testl %edx, %edx jne .L309 with the exception table generated for that 'mov' instruction causing us to jump to a stub that set %edx to -EFAULT and then jumped back to the 'testl' instruction. So not only do we now get rid of the extra code in the normal sequence, we also avoid unnecessarily keeping that extra error register live across it all.

Using a "jump to error label" interface is somewhat odd, but very convenient as a programming interface, and more importantly, it fits very well with simply making the target be the exception handler address directly from the inline asm. The reason it took over three years to actually do this? We need "asm goto" support for it, which only became the default on x86 last year. It's now been a year that we've forced asm goto support (see commit e501ce957a78 "x86: Force asm-goto"), and so let's just do it here too. [ Side note: this commit was originally done back in 2016. The above commentary about timing is obviously about it only now getting merged into my real upstream tree - Linus ] Sadly, gcc still only supports "asm goto" with asms that do not have any outputs, so we are limited to only the put_user case for this. Maybe in several more years we can do the get_user case too.

The root cause of the problem in commit '308c6cafde01' is: Reference to hns_nic_init_phy, the flag phydev->supported is changed after phy_connect_direct. The flag phydev->supported is 0x6ff when hns modules is loaded, so will not change Fiber Port power(Reference to marvell.c), which is power on at default. Then the flag phydev->supported is changed to 0x6f, so Fiber Port power is off when removing hns modules. When hns modules installed again, the flag phydev->supported is default value 0x6ff, so will not change Fiber Port power(now is off), causing mac link not up problem. So the solution is change phy flags before phy_connect_direct. Fixes: 308c6cafde01 ("net: hns: All ports can not work when insmod hns ko after rmmod.")

The mremap system call can be really slow if THP is not enabled. The bottleneck is move_page_tables, which is copying each pte at a time, and can be really slow across a large map. Turning on THP may not be a viable option, and is not for us. This patch speeds up the performance for non-THP system by copying at the PMD level when possible. The speedup is an order of magnitude on x86 (~20x). On a 1GB mremap, the mremap completion times drops from 3.4-3.6 milliseconds to 144-160 microseconds. Before: Total mremap time for 1GB data: 3521942 nanoseconds. Total mremap time for 1GB data: 3449229 nanoseconds. Total mremap time for 1GB data: 3488230 nanoseconds. After: Total mremap time for 1GB data: 150279 nanoseconds. Total mremap time for 1GB data: 144665 nanoseconds. Total mremap time for 1GB data: 158708 nanoseconds. If THP is enabled the optimization is mostly skipped except in certain situations.

This series speeds up the mremap(2) syscall by copying page tables at the PMD level even for non-THP systems. There is concern that the extra 'address' argument that mremap passes to pte_alloc may do something subtle architecture related in the future that may make the scheme not work. Also we find that there is no point in passing the 'address' to pte_alloc since its unused. This patch therefore removes this argument tree-wide resulting in a nice negative diff as well. Also ensuring along the way that the enabled architectures do not do anything funky with the 'address' argument that goes unnoticed by the optimization. Build and boot tested on x86-64.

So really, this macro can be only called from code that already includes fat.h. Hence, this patch moves it to fat.h, right after MSDOS_SB is defined. I also changed it to an inline function in order to save the double call to MSDOS_SB. This was suggested by joe@perches.com in the previous version. This patch is required for the next in the series, in which the variant (whether this is FAT12, FAT16 or FAT32) checks are replaced with new macros.

This patch was later reverted because, for very large environments, it meant more mount requests from clients and when there are a lot of clients this caused a fairly significant increase in server load. But there is a need for both types of expire check, depending on use case, so add a mount option to allow for strict update of last use of autofs dentrys (which just means not updating the last use on path walk access).

The check is unnecessary in all cases except for ioctl usage so placing the check in the super block accessor function adds a small overhead to the common case where it isn't needed. So it's sufficient to do this in the ioctl code only. Also the check in the ioctl code is needlessly complex.

For the blocking case, there is no need to constantly take and drop the spinlock, which is only needed to manipulate the waitqueue. The call to ep_events_available() is now lockless, and only exposed to benign races. Here, if false positive (returns available events and does not see another thread deleting an epi from the list) we call into send_events and then the list's state is correctly seen. Otoh, if a false negative and we don't see a list_add_tail(), for example, from irq callback, then it is rechecked again before blocking, which will see the correct state. In order for more accuracy to see concurrent list_del_init(), use the list_empty_careful() variant -- of course, this won't be safe against insertions from wakeup. For the overflow list we obviously need to prevent load/store tearing as we don't want to see partial values while the ready list is disabled.

This accounts for every time we check for ready events and also send events back to userspace; both callbacks, particularly the latter because of copy_to_user, can account for a non-trivial time. As such, the unlikely() check to see if the pointer is being used, seems both misleading and sub-optimal. In fact, we go to an awful lot of trouble to sync both lists, and populating the ovflist is far from an uncommon scenario. For example, profiling a concurrent epoll_wait(2) benchmark, with CONFIG_PROFILE_ANNOTATED_BRANCHES shows that for a two threads a 33% incorrect rate was seen; and when incrementally increasing the number of epoll instances (which is used, for example for multiple queuing load balancing models), up to a 90% incorrect rate was seen. Similarly, by deleting the prediction, 3% throughput boost was seen across incremental threads.

The following are some incremental optimizations on some of the epoll core. Each patch has the details, but together, the series is seen to shave off measurable cycles on a number of systems and workloads. For example, on a 40-core IB, a pipetest as well as parallel epoll_wait() benchmark show around a 20-30% increase in raw operations per second when the box is fully occupied (incremental thread counts), and up to 15% performance improvement with lower counts.

With gen_pool_first_fit_align() allocation function, the returned address should be aligned on the requested boundary. If chunk start address isn't aligned on the requested boundary, the returned address isn't aligned too. The only way to get properly aligned address is to initialize the pool with chunks aligned on the requested boundary. If want to have an ability to allocate buffers aligned on different boundaries (for example, 4K, 1MB, ...), the chunk start address should be aligned on the max possible alignment. This happens because gen_pool_first_fit_align() looks for properly aligned memory block without taking into account the chunk start address alignment. To fix this, we provide chunk start address to gen_pool_first_fit_align() and change its implementation such that it starts looking for properly aligned block with appropriate offset (exactly as is done in CMA).

At that time, BUILD_BUG_ON() was implemented with the negative array trick *and* the link-time trick, like this: extern int __build_bug_on_failed; #define BUILD_BUG_ON(condition) \ do { \ ((void)sizeof(char[1 - 2*!!(condition)])); \ if (condition) __build_bug_on_failed = 1; \ } while(0) Sparse is more strict about the negative array trick than GCC because Sparse requires the array length to be really constant. Here is the simple test code for the macro above: static const int x = 0; BUILD_BUG_ON(x); GCC is absolutely fine with it (-Wvla was enabled only very recently), but Sparse warns like this: error: bad constant expression error: cannot size expression (If you are using a newer version of Sparse, you will see a different warning message, "warning: Variable length array is used".) Anyway, Sparse was producing many false positives, and noisier than it should be at that time. With the previous commit, the leftover negative array trick is gone. Sparse is fine with the current BUILD_BUG_ON(), which is implemented by using the 'error' attribute. I am keeping the stub for BUILD_BUG_ON_ZERO(). Otherwise, Sparse would complain about the following code, which GCC is fine with: static const int x = 0; int y = BUILD_BUG_ON_ZERO(x); Link: http://lkml.kernel.org/r/1542856462-18836-3-git-send-email-yamada.masahiro@socionext.com Signed-off-by: Masahiro Yamada Acked-by: Kees Cook Reviewed-by: Luc Van Oostenryck Reviewed-by: Nick Desaulniers Tested-by: Nick Desaulniers Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds commit c60d3b79423aab402085c30b33bfff5354a61d8b Author: Masahiro Yamada Date: Thu Jan 3 15:26:20 2019 -0800 build_bug.h: remove negative-array fallback for BUILD_BUG_ON() The kernel can only be compiled with an optimization option (-O2, -Os, or the currently proposed -Og).

However, the network header length calculation is mainly for deriving the transport layer header in the key extraction process which the later fragment does not apply. Therefore, this commit skips the network header length calculation to fix the issue.

But experience has shown that people then decide not to do access_ok() at all, and instead rely on it being implied by other operations or similar. Which makes it very hard to verify that the access has actually been range-checked. If you use the unsafe direct user accesses, hardware features (either SMAP - Supervisor Mode Access Protection - on x86, or PAN - Privileged Access Never - on ARM) do force you to use user_access_begin(). But nothing really forces the range check. By putting the range check into user_access_begin(), we actually force people to do the right thing (tm), and the range check vill be visible near the actual accesses. We have way too long a history of people trying to avoid them.

The previous behavior would require reclaim up to 1 << order pages for skb aligned header_len of order > PAGE_ALLOC_COSTLY_ORDER before failing, otherwise the allocations in alloc_skb() would loop in the page allocator looking for memory. __GFP_RETRY_MAYFAIL makes both allocations failable under memory pressure, including for the HEAD allocation. This can cause, among many other things, write() to fail with ENOTCONN during RPC when under memory pressure. These allocations should succeed as they did previous to dcda9b04713c even if it requires calling the oom killer and additional looping in the page allocator to find memory. There is no way to specify the previous behavior of __GFP_REPEAT, but it's unlikely to be necessary since the previous behavior only guaranteed that 1 << order pages would be reclaimed before failing for order > PAGE_ALLOC_COSTLY_ORDER. That reclaim is not guaranteed to be contiguous memory, so repeating for such large orders is usually not beneficial. Removing the setting of __GFP_RETRY_MAYFAIL to restore the previous behavior, specifically not allowing alloc_skb() to fail for small orders and oom kill if necessary rather than allowing RPCs to fail.

It's not a huge deal: a missed user_access_end() will only mean that SMAP protection isn't active afterwards, and for the error case we'll be returning to user mode soon enough anyway. But it's wrong, and adding the proper user_access_end() is trivial enough (and doing it for the other error cases where it isn't needed doesn't hurt). I noticed it while doing the same prep-work for changing user_access_begin() that precipitated the access_ok() changes in commit 96d4f267e40f ("Remove 'type' argument from access_ok() function").

But the iteration count could be reported incorrectly, reporting impossibly high counts. That's because previous code uses the number of removed LBR entries for the iteration count. That's not good. Fix this by increasing the iteration count when a loop is detected. When matching the chain, the iteration count would be added up, finally we need to compute the average value when printing out.

For this reason, a #include of was added in ptrace.h, but it this turns out that this can interact badly with userspace code that tries to include ptrace.h on top of the libc headers (which may provide their own shadow definitions for sigcontext.h). To make the headers easier for userspace to consume, this patch bounces the common definitions into an __SVE_* namespace and moves them to a backend header that can be included by the other headers as appropriate. This should allow ptrace.h to be used alongside libc's sigcontext.h (if any) without ill effects. This should make the situation unambiguous: is the header to include for the sigframe-specific definitions, while is the header to include for ptrace-specific definitions. To avoid conflicting with existing usage, remains the canonical way to get the common definitions for SVE_VQ_MIN, sve_vq_from_vl() etc., both in userspace and in the kernel: relying on these being defined as a side effect of including just was never intended to be safe.

However, currently SVE_PT_REGS_OFFSET is defined in terms of struct sve_context, which is wrong: that structure describes the SVE header in the signal frame, not in the ptrace regset. This patch fixes the definition to use the ptrace header structure struct user_sve_header instead. By good fortune, the two structures are the same size anyway, so there is no functional or ABI change.

This affects the scpi and scmi cpufreq drivers which no longer free OPPs on failures or on invocations of the policy->exit() callback. Create a generic OPP helper dev_pm_opp_remove_all_dynamic() which can be called from these drivers instead of dev_pm_opp_cpumask_remove_table(). In dev_pm_opp_remove_all_dynamic(), we need to make sure that the opp_list isn't getting accessed simultaneously from other parts of the OPP core while the helper is freeing dynamic OPPs, i.e. we can't drop the opp_table->lock while traversing through the OPP list. And to accomplish that, this patch also creates _opp_kref_release_unlocked() which can be called from this new helper with the opp_table lock already held.

It existed because the original 80386 would not honor the write protect bit when in kernel mode, so you had to do COW by hand before doing any user access. But we haven't supported that in a long time, and these days the 'type' argument is a purely historical artifact. A discussion about extending 'user_access_begin()' to do the range checking resulted this patch, because there is no way we're going to move the old VERIFY_xyz interface to that model. And it's best done at the end of the merge window when I've done most of my merges, so let's just get this done once and for all. This patch was mostly done with a sed-script, with manual fix-ups for the cases that weren't of the trivial 'access_ok(VERIFY_xyz' form. There were a couple of notable cases: - csky still had the old "verify_area()" name as an alias. - the iter_iov code had magical hardcoded knowledge of the actual values of VERIFY_{READ,WRITE} (not that they mattered, since nothing really used it) - microblaze used the type argument for a debug printout but other than those oddities this should be a total no-op patch. I tried to fix up all architectures, did fairly extensive grepping for access_ok() uses, and the changes are trivial, but I may have missed something. Any missed conversion should be trivially fixable, though.

The wait4() call will not return because it's waiting for the child process "sleep 1000" to end. So 'perf stat' doesn't return even after 5s passes.

The tps6586x-rtc device is one of its children that uses the tps6586x irqchip. When using the tps6586x-rtc as a wake-up device from suspend, the following is seen: PM: Syncing filesystems ... done. Freezing user space processes ... (elapsed 0.001 seconds) done. OOM killer disabled. Freezing remaining freezable tasks ... (elapsed 0.000 seconds) done. Disabling non-boot CPUs ... Entering suspend state LP1 Enabling non-boot CPUs ... CPU1 is up tps6586x 3-0034: failed to read interrupt status tps6586x 3-0034: failed to read interrupt status The reason why the tps6586x interrupt status cannot be read is because the tps6586x interrupt is not masked during suspend and when the tps6586x-rtc interrupt occurs, to wake-up the device, the interrupt is seen before the i2c controller has been resumed in order to read the tps6586x interrupt status. The tps6586x-rtc driver sets it's interrupt as a wake-up source during suspend, which gets propagated to the parent tps6586x interrupt. However, the tps6586x-rtc driver cannot disable it's interrupt during suspend otherwise we would never be woken up and so the tps6586x must disable it's interrupt instead. Prevent the tps6586x interrupt handler from executing on exiting suspend before the i2c controller has been resumed by disabling the tps6586x interrupt on entering suspend and re-enabling it on resuming from suspend.

The initial slow load still precedes the latter ALU ops on that register, so the CPU executes speculatively from that point. Once we have the known scalar, any compare operation would work then. A third option only involving registers with known scalars could be crafted as described in [0] where a CPU port (e.g. Slow Int unit) would be filled with many dependent computations such that the subsequent condition depending on its outcome has to wait for evaluation on its execution port and thereby executing speculatively if the speculated code can be scheduled on a different execution port, or any other form of mistraining as described in [1], for example. Given this is not limited to only unknown scalars, not only map but also stack access is affected since both is accessible for unprivileged users and could potentially be used for out of bounds access under speculation. In order to prevent any of these cases, the verifier is now sanitizing pointer arithmetic on the offset such that any out of bounds speculation would be masked in a way where the pointer arithmetic result in the destination register will stay unchanged, meaning offset masked into zero similar as in array_index_nospec() case. With regards to implementation, there are three options that were considered: i) new insn for sanitation, ii) push/pop insn and sanitation as inlined BPF, iii) reuse of ax register and sanitation as inlined BPF. Option i) has the downside that we end up using from reserved bits in the opcode space, but also that we would require each JIT to emit masking as native arch opcodes meaning mitigation would have slow adoption till everyone implements it eventually which is counter-productive. Option ii) and iii) have both in common that a temporary register is needed in order to implement the sanitation as inlined BPF since we are not allowed to modify the source register. While a push / pop insn in ii) would be useful to have in any case, it requires once again that every JIT needs to implement it first. While possible, amount of changes needed would also be unsuitable for a -stable patch. Therefore, the path which has fewer changes, less BPF instructions for the mitigation and does not require anything to be changed in the JITs is option iii) which this work is pursuing. The ax register is already mapped to a register in all JITs (modulo arm32 where it's mapped to stack as various other BPF registers there) and used in constant blinding for JITs-only so far. It can be reused for verifier rewrites under certain constraints. The interpreter's tmp "register" has therefore been remapped into extending the register set with hidden ax register and reusing that for a number of instructions that needed the prior temporary variable internally (e.g. div, mod). This allows for zero increase in stack space usage in the interpreter, and enables (restricted) generic use in rewrites otherwise as long as such a patchlet does not make use of these instructions. The sanitation mask is dynamic and relative to the offset the map value or stack pointer currently holds. There are various cases that need to be taken under consideration for the masking, e.g. such operation could look as follows: ptr += val or val += ptr or ptr -= val. Thus, the value to be sanitized could reside either in source or in destination register, and the limit is different depending on whether the ALU op is addition or subtraction and depending on the current known and bounded offset. The limit is derived as follows: limit := max_value_size - (smin_value + off). For subtraction: limit := umax_value + off. This holds because we do not allow any pointer arithmetic that would temporarily go out of bounds or would have an unknown value with mixed signed bounds where it is unclear at verification time whether the actual runtime value would be either negative or positive. For example, we have a derived map pointer value with constant offset and bounded one, so limit based on smin_value works because the verifier requires that statically analyzed arithmetic on the pointer must be in bounds, and thus it checks if resulting smin_value + off and umax_value + off is still within map value bounds at time of arithmetic in addition to time of access. Similarly, for the case of stack access we derive the limit as follows: MAX_BPF_STACK + off for subtraction and -off for the case of addition where off := ptr_reg->off + ptr_reg->var_off.value. Subtraction is a special case for the masking which can be in form of ptr += -val, ptr -= -val, or ptr -= val. In the first two cases where we know that the value is negative, we need to temporarily negate the value in order to do the sanitation on a positive value where we later swap the ALU op, and restore original source register if the value was in source. The sanitation of pointer arithmetic alone is still not fully sufficient as is, since a scenario like the following could happen ... PTR += 0x1000 (e.g. K-based imm) PTR -= BIG_NUMBER_WITH_SLOW_COMPARISON PTR += 0x1000 PTR -= BIG_NUMBER_WITH_SLOW_COMPARISON [...] ... which under speculation could end up as ... PTR += 0x1000 PTR -= 0 [ truncated by mitigation ] PTR += 0x1000 PTR -= 0 [ truncated by mitigation ] [...] ... and therefore still access out of bounds. To prevent such case, the verifier is also analyzing safety for potential out of bounds access under speculative execution. Meaning, it is also simulating pointer access under truncation. We therefore "branch off" and push the current verification state after the ALU operation with known 0 to the verification stack for later analysis. Given the current path analysis succeeded it is likely that the one under speculation can be pruned. In any case, it is also subject to existing complexity limits and therefore anything beyond this point will be rejected. In terms of pruning, it needs to be ensured that the verification state from speculative execution simulation must never prune a non-speculative execution path, therefore, we mark verifier state accordingly at the time of push_stack(). If verifier detects out of bounds access under speculative execution from one of the possible paths that includes a truncation, it will reject such program. Given we mask every reg-based pointer arithmetic for unprivileged programs, we've been looking into how it could affect real-world programs in terms of size increase. As the majority of programs are targeted for privileged-only use case, we've unconditionally enabled masking (with its alu restrictions on top of it) for privileged programs for the sake of testing in order to check i) whether they get rejected in its current form, and ii) by how much the number of instructions and size will increase. We've tested this by using Katran, Cilium and test_l4lb from the kernel selftests. For Katran we've evaluated balancer_kern.o, Cilium bpf_lxc.o and an older test object bpf_lxc_opt_-DUNKNOWN.o and l4lb we've used test_l4lb.o as well as test_l4lb_noinline.o. We found that none of the programs got rejected by the verifier with this change, and that impact is rather minimal to none. balancer_kern.o had 13,904 bytes (1,738 insns) xlated and 7,797 bytes JITed before and after the change. Most complex program in bpf_lxc.o had 30,544 bytes (3,817 insns) xlated and 18,538 bytes JITed before and after and none of the other tail call programs in bpf_lxc.o had any changes either. For the older bpf_lxc_opt_-DUNKNOWN.o object we found a small increase from 20,616 bytes (2,576 insns) and 12,536 bytes JITed before to 20,664 bytes (2,582 insns) and 12,558 bytes JITed after the change. Other programs from that object file had similar small increase. Both test_l4lb.o had no change and remained at 6,544 bytes (817 insns) xlated and 3,401 bytes JITed and for test_l4lb_noinline.o constant at 5,080 bytes (634 insns) xlated and 3,313 bytes JITed. This can be explained in that LLVM typically optimizes stack based pointer arithmetic by using K-based operations and that use of dynamic map access is not overly frequent. However, in future we may decide to optimize the algorithm further under known guarantees from branch and value speculation. Latter seems also unclear in terms of prediction heuristics that today's CPUs apply as well as whether there could be collisions in e.g. the predictor's Value History/Pattern Table for triggering out of bounds access, thus masking is performed unconditionally at this point but could be subject to relaxation later on. We were generally also brainstorming various other approaches for mitigation, but the blocker was always lack of available registers at runtime and/or overhead for runtime tracking of limits belonging to a specific pointer. Thus, we found this to be minimally intrusive under given constraints. With that in place, a simple example with sanitized access on unprivileged load at post-verification time looks as follows: # bpftool prog dump xlated id 282 [...] 28: (79) r1 = *(u64 *)(r7 +0) 29: (79) r2 = *(u64 *)(r7 +8) 30: (57) r1 &= 15 31: (79) r3 = *(u64 *)(r0 +4608) 32: (57) r3 &= 1 33: (47) r3 |= 1 34: (2d) if r2 > r3 goto pc+19 35: (b4) (u32) r11 = (u32) 20479 | 36: (1f) r11 -= r2 | Dynamic sanitation for pointer 37: (4f) r11 |= r2 | arithmetic with registers 38: (87) r11 = -r11 | containing bounded or known 39: (c7) r11 s>>= 63 | scalars in order to prevent 40: (5f) r11 &= r2 | out of bounds speculation. 41: (0f) r4 += r11 | 42: (71) r4 = *(u8 *)(r4 +0) 43: (6f) r4 <<= r1 [...] For the case where the scalar sits in the destination register as opposed to the source register, the following code is emitted for the above example: [...] 16: (b4) (u32) r11 = (u32) 20479 17: (1f) r11 -= r2 18: (4f) r11 |= r2 19: (87) r11 = -r11 20: (c7) r11 s>>= 63 21: (5f) r2 &= r11 22: (0f) r2 += r0 23: (61) r0 = *(u32 *)(r2 +0) [...] JIT blinding example with non-conflicting use of r10: [...] d5: je 0x0000000000000106 _ d7: mov 0x0(%rax),%edi | da: mov $0xf153246,%r10d | Index load from map value and e0: xor $0xf153259,%r10 | (const blinded) mask with 0x1f. e7: and %r10,%rdi |_ ea: mov $0x2f,%r10d | f0: sub %rdi,%r10 | Sanitized addition.

However, even though the reg->smin_value could have a negative value, the final result of the sum with off could be positive when pointer arithmetic with known and unknown scalars is combined. In this case we reject the program with an error such as "R min value is negative, either use unsigned index or do a if (index >=0) check." even though the access itself would be fine. Therefore extend the check to probe whether the actual resulting reg->smin_value + off is less than zero.

However, it can be made to work in that blinding will be skipped if there is prior use in either source or destination register on the instruction.

It was wrongly claiming that the ordering wasn't necessary. The memory barrier _is_ necessary. If something is truly polling and not going to sleep, it's the whole state setting that is unnecessary, not the memory barrier. Whenever you set your state to a sleeping state, you absolutely need the memory barrier. Note that sometimes the memory barrier can be elsewhere. For example, the ordering might be provided by an external lock, or by setting the process state to sleeping before adding yourself to the wait queue list that is used for waking up (where the wait queue lock itself will guarantee that any wakeup will correctly see the sleeping state). But none of those cases were true here. NOTE! Some of the polling paths may indeed be able to drop the state setting entirely, at which point the memory barrier also goes away. (Also note that this doesn't revert the TASK_RUNNING cases: there is no race between a wakeup and setting the process state to TASK_RUNNING, since the end result doesn't depend on ordering).

When the next reply comes in, the reply handler will stomp on the rl_reply field, leaking the old rep. A trace event is added to capture such leaks. This problem seems to be worsened by the restructuring of the RPC Call path in v4.20. Fully addressing this issue will require at least a re-architecture of the disconnect logic, which is not appropriate during -rc.

RFC 8267 Section 6.3 requires NFSv4 clients to use "the alternative well-known port number", which is 20049. Make the use of the well- known port number automatic, just as it is for NFS/TCP and port 2049. For NFSv2/3, Section 4.2 allows clients to simply choose 20049 as the default or use rpcbind. I don't know of an NFS/RDMA server implementation that registers it's NFS/RDMA service with rpcbind, so automatically choosing 20049 seems like the better choice. The other widely-deployed NFS/RDMA client, Solaris, also uses 20049 as the default port.

The XID adds more uniqueness to each RDMA segment to reduce the likelihood of a software bug on the server reading from or writing into memory it's not supposed to. - On-the-wire RDMA Read and Write requests do not otherwise carry any identifier that matches them up to an RPC. The XID in the upper 32 bits will act as an eye-catcher in network captures.

It is also less secure than FRWR because an FMR memory registration can expose adjacent bytes to remote reading or writing. As discussed during the RDMA BoF at LPC 2018, it is time to remove support for FMR in the NFS/RDMA client stack. Note that NFS/RDMA server-side uses either local memory registration or FRWR. FMR is not used. There are a few Infiniband/RoCE devices in the kernel tree that do not appear to support MEM_MGT_EXTENSIONS (FRWR), and therefore will not support client-side NFS/RDMA after this patch. These are: - mthca - qib - hns (RoCE) Users of these devices can use NFS/TCP on IPoIB instead.

By default, the RDMA R/W core API uses max_sge_rd as the maximum page depth for MRs. For some devices, the value of max_sge_rd is 1, which is also not optimal. Thus, when max_sge_rd is larger than 1, use that value. Otherwise use the value of the max_fast_reg_page_list_len attribute. I've tested this with CX-3 Pro, FastLinq, and CX-5 devices. It reproducibly improves the throughput of large I/Os by several percent.

This window apparently does not exist for socket transports because there is a lock held while a reply is being received which prevents the wake-up call until after reply processing is done. To resolve this, all RPC replies being processed on an RPC-over-RDMA transport have to complete before pending tasks are awoken due to a transport disconnect. Callers that already hold the transport write lock may invoke ->ops->close directly. Others use a generic helper that schedules a close when the write lock can be taken safely.

Actually the two have only an indirect relationship. It's in fact impossible to guess reliably whether the MR has been DMA unmapped based on its fr_state field, especially as the surrounding code and its assumptions have changed over time. A better approach is to track the DMA mapping status explicitly so that the recycler is less brittle to unexpected situations, and attempts to DMA-unmap a second time are prevented.

However, the interrupt source changes along with the last selected source (ie. the last read sensor), which is an inconsistent behavior. Avoid possible glitches by always selecting back only one channel which will then be referenced as the "overheat_sensor" (arbitrarily: the first in the DT which has a critical trip point filled in). It is possible that the scan of all thermal zone nodes did not bring a critical trip point from which the overheat interrupt could be configured. In this case just complain but do not fail the probe. Also disable sensor switch during overheat situations because changing the channel while the system is too hot could clear the overheat state by changing the source while the temperature is still very high. Even if the overheat state is not declared, overheat interrupt must be cleared by reading the DFX interrupt cause _after_ the temperature has fallen down to the low threshold, otherwise future possible interrupts would not be served. A work polls the corresponding register until the overheat flag gets cleared in this case.

Wysocki commit 75cb8d20c112aba70f23d98e3f8d0a38ace16006 Author: Richard Zhu Date: Fri Dec 21 04:33:38 2018 +0000 PCI: imx: Enable MSI from downstream components The MSI Enable bit in the MSI Capability (PCIe r4.0, sec 7.7.1.2) controls whether a Function can request service using MSI. i.MX6 Root Ports implement the MSI Capability and may use MSI to request service for events like PME, hotplug, AER, etc. In addition, on i.MX6, the MSI Enable bit controls delivery of MSI interrupts from components below the Root Port. Prior to f3fdfc4ac3a2 ("PCI: Remove host driver Kconfig selection of CONFIG_PCIEPORTBUS"), enabling CONFIG_PCI_IMX6 automatically also enabled CONFIG_PCIEPORTBUS, and when portdrv claimed the Root Ports, it set the MSI Enable bit so it could use PME, hotplug, AER, etc. As a side effect, that also enabled delivery of MSI interrupts from downstream components. The imx6q-pcie driver itself does not depend on portdrv, so set MSI Enable in imx6q-pcie so MSI from downstream components works even if nobody uses MSI for the Root Port events.

The automatic DSP detection and skip of binding with the legacy driver caused regressions on several machines like Dell XPS13. They give the PCI class 0x40380 indicating the availability of DSP while they don't work with ASoC SKL driver (yet). As the support of ASoC driver for such devices isn't available, it's better to revert the whole DSP-detection-and-skip behavior of the legacy driver, so that we can get the old good driver working on such devices. The pci_binding option for ASoC SKL driver is still kept so that it can work without blacklisting.

On a 32 bit architecture, we might run into situations of unsafe access as the access to the field becomes non atomic. Use seqlocks for synchronization. This allows us to avoid using spinlocks for readers as readers do not need mutual exclusion. Another approach to solve this is to require sk_lock for all modifications of the timestamps. The current approach allows for timestamps to have their own lock: sk_stamp_lock. This allows for the patch to not compete with already existing critical sections, and side effects are limited to the paths in the patch. The addition of the new field maintains the data locality optimizations from commit 9115e8cd2a0c ("net: reorganize struct sock for better data locality") Note that all the instances of the sk_stamp accesses are either through the ioctl or the syscall recvmsg.

Most of these have been covered and described in the other branches, we mostly keep defconfig separate to avoid conflicts between SoC/dt/driver updates that they otherwise would be grouped with. One thing worth mentioning here is that OMAP changes from using their own UART driver, to 8250, for the multi_v7_defconfig shared config on 32-bit. This means that the console is now named ttyS* instead of ttyO*. This change was already done for omap2_defconfig a while back, so most users of these configs have either already updated, or can easily follow the same patterns as they did at that time.

The individual updates are too many to enumerate, many many platforms have seen additions of device descriptions such that they are functionally more complete (in fact, this is often the bulk of updates we see). Instead I've mostly focused on highlighting the new platforms below as they are introduced. Sometimes the introduction is of mostly a fragment, that later gets filled in on later releases, and in some cases it's near-complete platform support. The latter is more common for derivative platforms that already has similar support in-tree. Two SoCs are slight outliers from the usual range of additions. Allwinner support for F1C100s, a quite old SoC (ARMv5-based) shipping in the Lychee Pi Nano platform. At the other end is NXP Layerscape LX2160A, a 16-core 2.2GHz Cortex-A72 SoC with a large amount of I/O aimed at infrastructure/networking. TI updates stick out in the diff stats too, in particular because they have moved the description of their L4 on-chip interconnect to devicetree, which opens up for removal of even more of their platform-specific 'hwmod' description tables over the next few releases.

This will allow for multiple users of hooking onto functions to get the callback (return) of the function.

That commit added a struct blk_mq_tag_set to struct floppy_state and initialized it with a blk_mq_init_sq_queue() call. Unfortunately, there is a memset() in swim3_add_device() that subsequently clears the floppy_state struct. That means fs->tag_set->ops is a NULL pointer, and it gets dereferenced by blk_mq_free_rqs() which gets called in the request_irq() error path. Move the memset() to fix this bug. BTW, the request_irq() failure for the left mediabay floppy (fd1) is not a regression. I don't know why it happens. The right media bay floppy (fd0) works fine however.

This results in a large number of file system errors, and since we can't lock the buffer head when marking the superblock dirty in the ext4_grp_locked_error() case, it's possible the superblock to be !buffer_uptodate() without buffer_write_io_error() being true. We need to set buffer_uptodate() before we call mark_buffer_dirty() or this will trigger a WARN_ON. It's safe to do this since the superblock must have been properly read into memory or the mount would have been successful. So if buffer_uptodate() is not set, we can safely assume that this happened due to a failed attempt to write the superblock.

Do a (manual) revert of: a9e7f6544b9c ("sched/fair: Fix O(nr_cgroups) in load balance path") It turns out that the list_del_leaf_cfs_rq() introduced by this commit is a surprising property that was not considered in followup commits such as: 9c2791f936ef ("sched/fair: Fix hierarchical order in rq->leaf_cfs_rq_list") As Vincent Guittot explains: "I think that there is a bigger problem with commit a9e7f6544b9c and cfs_rq throttling: Let take the example of the following topology TG2 --> TG1 --> root: 1) The 1st time a task is enqueued, we will add TG2 cfs_rq then TG1 cfs_rq to leaf_cfs_rq_list and we are sure to do the whole branch in one path because it has never been used and can't be throttled so tmp_alone_branch will point to leaf_cfs_rq_list at the end. 2) Then TG1 is throttled 3) and we add TG3 as a new child of TG1. 4) The 1st enqueue of a task on TG3 will add TG3 cfs_rq just before TG1 cfs_rq and tmp_alone_branch will stay on rq->leaf_cfs_rq_list. With commit a9e7f6544b9c, we can del a cfs_rq from rq->leaf_cfs_rq_list. So if the load of TG1 cfs_rq becomes NULL before step 2) above, TG1 cfs_rq is removed from the list. Then at step 4), TG3 cfs_rq is added at the beginning of rq->leaf_cfs_rq_list but tmp_alone_branch still points to TG3 cfs_rq because its throttled parent can't be enqueued when the lock is released. tmp_alone_branch doesn't point to rq->leaf_cfs_rq_list whereas it should. So if TG3 cfs_rq is removed or destroyed before tmp_alone_branch points on another TG cfs_rq, the next TG cfs_rq that will be added, will be linked outside rq->leaf_cfs_rq_list - which is bad. In addition, we can break the ordering of the cfs_rq in rq->leaf_cfs_rq_list but this ordering is used to update and propagate the update from leaf down to root." Instead of trying to work through all these cases and trying to reproduce the very high loads that produced the lockup to begin with, simplify the code temporarily by reverting a9e7f6544b9c - which change was clearly not thought through completely.

Signed-off-by: Douglas Anderson Acked-by: Daniel Thompson Signed-off-by: Daniel Thompson commit 87b095928584da7d5cb3149016f00b0b139c2292 Author: Douglas Anderson Date: Tue Dec 4 19:38:27 2018 -0800 kgdb: Don't round up a CPU that failed rounding up before If we're using the default implementation of kgdb_roundup_cpus() that uses smp_call_function_single_async() we can end up hanging kgdb_roundup_cpus() if we try to round up a CPU that failed to round up before. Specifically smp_call_function_single_async() will try to wait on the csd lock for the CPU that we're trying to round up. If the previous round up never finished then that lock could still be held and we'll just sit there hanging. There's not a lot of use trying to round up a CPU that failed to round up before. Let's keep a flag that indicates whether the CPU started but didn't finish to round up before. If we see that flag set then we'll skip the next round up. In general we have a few goals here: - We never want to end up calling smp_call_function_single_async() when the csd is still locked. This is accomplished because flush_smp_call_function_queue() unlocks the csd _before_ invoking the callback. That means that when kgdb_nmicallback() runs we know for sure the the csd is no longer locked. Thus when we set "rounding_up = false" we know for sure that the csd is unlocked. - If there are no timeouts rounding up we should never skip a round up. NOTE #1: In general trying to continue running after failing to round up CPUs doesn't appear to be supported in the debugger. When I simulate this I find that kdb reports "Catastrophic error detected" when I try to continue. I can overrule and continue anyway, but it should be noted that we may be entering the land of dragons here. Possibly the "Catastrophic error detected" was added _because_ of the future failure to round up, but even so this is an area of the code that hasn't been strongly tested. NOTE #2: I did a bit of testing before and after this change. I introduced a 10 second hang in the kernel while holding a spinlock that I could invoke on a certain CPU with 'taskset -c 3 cat /sys/...". Before this change if I did: - Invoke hang - Enter debugger - g (which warns about Catastrophic error, g again to go anyway) - g - Enter debugger ...I'd hang the rest of the 10 seconds without getting a debugger prompt. After this change I end up in the debugger the 2nd time after only 1 second with the standard warning about 'Timed out waiting for secondary CPUs.' I'll also note that once the CPU finished waiting I could actually debug it (aka "btc" worked) I won't promise that everything works perfectly if the errant CPU comes back at just the wrong time (like as we're entering or exiting the debugger) but it certainly seems like an improvement. NOTE #3: setting 'kgdb_info[cpu].rounding_up = false' is in kgdb_nmicallback() instead of kgdb_call_nmi_hook() because some implementations override kgdb_call_nmi_hook(). It shouldn't hurt to have it in kgdb_nmicallback() in any case. NOTE #4: this logic is really only needed because there is no API call like "smp_try_call_function_single_async()" or "smp_csd_is_locked()". If such an API existed then we'd use it instead, but it seemed a bit much to add an API like this just for kgdb.

If nothing else that seems like it could violate spinlock semantics and cause a deadlock. Instead, let's use a private csd alongside smp_call_function_single_async() to round up the other CPUs. Using smp_call_function_single_async() doesn't require interrupts to be enabled so we can remove the offending bit of code. In order to avoid duplicating this across all the architectures that use the default kgdb_roundup_cpus(), we'll add a "weak" implementation to debug_core.c. Looking at all the people who previously had copies of this code, there were a few variants. I've attempted to keep the variants working like they used to. Specifically: * For arch/arc we passed NULL to kgdb_nmicallback() instead of get_irq_regs(). * For arch/mips there was a bit of extra code around kgdb_nmicallback() NOTE: In this patch we will still get into trouble if we try to round up a CPU that failed to round up before. We'll try to round it up again and potentially hang when we try to grab the csd lock. That's not new behavior but we'll still try to do better in a future patch.

Also from Florian. 4) Restart node lookup from the insertion path, after releasing nodes via packet path garbage collection. Shawn Bohrer described a scenario that may result in inserting a connection in an already dead list node. Patch from Florian. 5) Merge lookup and add function to avoid a hold release and re-grab. From Florian. 6) Be safe and iterate over the node lists under the spinlock. 7) Speculative list nodes removal via garbage collection, check if list node got a connection while it was scheduled for deletion via gc. 8) Accidental argument swap in find_next_bit() that leads to more frequent scheduling of the workqueue.

To register and unregister the device, the pointer 'gd.cd_info' is passed to the functions register_cdrom() and unregister_cdrom(), respectively. However, this buffer is not freed after it is used, which can cause a memory leak bug. This patch simply frees the buffer 'gd.cd_info' in exit_gdrom() to fix the above issue.

Shawn tracked this down to bogus 'parent' pointer: Problem is that when we insert a new node, then there is a chance that the 'parent' that we found was also passed to tree_nodes_free() (because that node was empty) for erase+free. Instead of trying to be clever and detect when this happens, restart the search if we have evicted one or more nodes. To prevent frequent restarts, do not perform gc on the second round. Also, unconditionally schedule the gc worker. The condition gc_count > ARRAY_SIZE(gc_nodes)) cannot be true unless tree grows very large, as the height of the tree will be low even with hundreds of nodes present.

To fix this, split gc into two phases. One phase to perform gc on the connections: From a locking perspective, this is the same as count_tree(): we hold rcu lock, but we do not change the tree, we only change the nodes' contents. The second phase acquires the tree lock and reaps empty nodes. This avoids a race condition of the garbage collection vs. packet path: If a node has been free'd already, the second phase won't find it anymore. This second phase is, from locking perspective, same as insert_tree(). The former only modifies nodes (list content, count), latter modifies the tree itself (rb_erase or rb_insert).

The userspace tooling for this capability is still a work in progress, but the changes survive the existing libnvdimm unit tests. The changes also pass manual checkout on hardware and the new nfit_test emulation of the security capability. The touches of the security/keys/ files have received the necessary acks from Mimi and David. Those changes were necessary to allow for a new generic encrypted-key type, and allow the nvdimm sub-system to lookup key material referenced by the libnvdimm-sysfs interface. Summary: - Add support for the security features of nvdimm devices that implement a security model similar to ATA hard drive security. The security model supports locking access to the media at device-power-loss, to be unlocked with a passphrase, and secure-erase (crypto-scramble). Unlike the ATA security case where the kernel expects device security to be managed in a pre-OS environment, the libnvdimm security implementation allows key provisioning and key-operations at OS runtime. Keys are managed with the kernel's encrypted-keys facility to provide data-at-rest security for the libnvdimm key material. The usage model mirrors fscrypt key management, but is driven via libnvdimm sysfs. - Miscellaneous updates for api usage and comment fixes" * tag 'libnvdimm-for-4.21' of git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm: (21 commits) libnvdimm/security: Quiet security operations libnvdimm/security: Add documentation for nvdimm security support tools/testing/nvdimm: add Intel DSM 1.8 support for nfit_test tools/testing/nvdimm: Add overwrite support for nfit_test tools/testing/nvdimm: Add test support for Intel nvdimm security DSMs acpi/nfit, libnvdimm/security: add Intel DSM 1.8 master passphrase support acpi/nfit, libnvdimm/security: Add security DSM overwrite support acpi/nfit, libnvdimm: Add support for issue secure erase DSM to Intel nvdimm acpi/nfit, libnvdimm: Add enable/update passphrase support for Intel nvdimms acpi/nfit, libnvdimm: Add disable passphrase support to Intel nvdimm. acpi/nfit, libnvdimm: Add unlock of nvdimm support for Intel DIMMs acpi/nfit, libnvdimm: Add freeze security support to Intel nvdimm acpi/nfit, libnvdimm: Introduce nvdimm_security_ops keys-encrypted: add nvdimm key format type to encrypted keys keys: Export lookup_user_key to external users acpi/nfit, libnvdimm: Store dimm id as a member to struct nvdimm libnvdimm, namespace: Replace kmemdup() with kstrndup() libnvdimm, label: Switch to bitmap_zalloc() ACPI/nfit: Adjust annotation for why return 0 if fail to find NFIT at start libnvdimm, bus: Check id immediately following ida_simple_get ... commit 4ed7bdc1eb4c82cf4bfdf6a94dd36fd695f6f387 Merge: 5d24ae67a961c c6d6e9b0f6b42 Author: Linus Torvalds Date: Fri Dec 28 15:02:26 2018 -0800 Merge tag 'for-4.21/dm-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm Pull device mapper updates from Mike Snitzer: - Eliminate a couple indirect calls from bio-based DM core. - Fix DM to allow reads that exceed readahead limits by setting io_pages in the backing_dev_info. - A couple code cleanups in request-based DM. - Fix various DM targets to check for device sector overflow if CONFIG_LBDAF is not set. - Use u64 instead of sector_t to store iv_offset in DM crypt; sector_t isn't large enough on 32bit when CONFIG_LBDAF is not set. - Performance fixes to DM's kcopyd and the snapshot target focused on limiting memory use and workqueue stalls. - Fix typos in the integrity and writecache targets. - Log which algorithm is used for dm-crypt's encryption and dm-integrity's hashing. - Fix false -EBUSY errors in DM raid target's handling of check/repair messages. - Fix DM flakey target's corrupt_bio_byte feature to reliably corrupt the Nth byte in a bio's payload. * tag 'for-4.21/dm-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm: dm: do not allow readahead to limit IO size dm raid: fix false -EBUSY when handling check/repair message dm rq: cleanup leftover code from recently removed q->mq_ops branching dm verity: log the hash algorithm implementation dm crypt: log the encryption algorithm implementation dm integrity: fix spelling mistake in workqueue name dm flakey: Properly corrupt multi-page bios. dm: Check for device sector overflow if CONFIG_LBDAF is not set dm crypt: use u64 instead of sector_t to store iv_offset dm kcopyd: Fix bug causing workqueue stalls dm snapshot: Fix excessive memory usage and workqueue stalls dm bufio: update comment in dm-bufio.c dm writecache: fix typo in error msg for creating writecache_flush_thread dm: remove indirect calls from __send_changing_extent_only() dm mpath: only flush workqueue when needed dm rq: remove unused arguments from rq_completed() dm: avoid indirect call in __dm_make_request commit 5d24ae67a961c51beb255a28c9c417d9710247c2 Merge: 938edb8a31b97 f617e5ffe04fd Author: Linus Torvalds Date: Fri Dec 28 14:57:10 2018 -0800 Merge tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/rdma/rdma Pull rdma updates from Jason Gunthorpe: "This has been a fairly typical cycle, with the usual sorts of driver updates.

This does not include the clock_adjtime, getrusage/waitid, and getitimer/setitimer system calls. I still plan to have new versions of those as well, but they are not required for correct operation of the C library since they can be emulated using the old 32-bit time_t based system calls.

So during swapin, a new copy of the page need to be generated if a different anon_vma is needed, please refer to comments of ksm_might_need_to_copy() for details. During swapoff, unuse_vma() uses anon_vma (if available) to locate VMA and virtual address mapped to the page, so not all mappings to a swapped out KSM page could be found. So in try_to_unuse(), even if the swap count of a swap entry isn't zero, the page needs to be deleted from swap cache, so that, in the next round a new page could be allocated and swapin for the other mappings of the swapped out KSM page. But this contradicts with the THP swap support. Where the THP could be deleted from swap cache only after the swap count of every swap entry in the huge swap cluster backing the THP has reach 0. So try_to_unuse() is changed in commit e07098294adf ("mm, THP, swap: support to reclaim swap space for THP swapped out") to check that before delete a page from swap cache, but this has broken KSM swapoff too. Fortunately, KSM is for the normal pages only, so the original behavior for KSM pages could be restored easily via checking PageTransCompound(). That is how this patch works. The bug is introduced by e07098294adf ("mm, THP, swap: support to reclaim swap space for THP swapped out"), which is merged by v4.14-rc1. So I think we should backport the fix to from 4.14 on. But Hugh thinks it may be rare for the KSM pages being in the swap device when swapoff, so nobody reports the bug so far.

Current code in the page fault path attempts to handle this by 'backing out' operations if we encounter the race. One obvious omission in the current code is removing a page newly added to the page cache. This is pretty straight forward to address, but there is a more subtle and difficult issue of backing out hugetlb reservations. To handle this correctly, the 'reservation state' before page allocation needs to be noted so that it can be properly backed out. There are four distinct possibilities for reservation state: shared/reserved, shared/no-resv, private/reserved and private/no-resv. Backing out a reservation may require memory allocation which could fail so that needs to be taken into account as well. Instead of writing the required complicated code for this rare occurrence, just eliminate the race. i_mmap_rwsem is now held in read mode for the duration of page fault processing. Hold i_mmap_rwsem longer in truncation and hold punch code to cover the call to remove_inode_hugepages. With this modification, code in remove_inode_hugepages checking for races becomes 'dead' as it can not longer happen. Remove the dead code and expand comments to explain reasoning. Similarly, checks for races with truncation in the page fault path can be simplified and removed.

Consider the following: A task takes a page fault on a shared hugetlbfs file and calls huge_pte_alloc to get a ptep. Suppose the returned ptep points to a shared pmd. Now, another task truncates the hugetlbfs file. As part of truncation, it unmaps everyone who has the file mapped. If the range being truncated is covered by a shared pmd, huge_pmd_unshare will be called. For all but the last user of the shared pmd, huge_pmd_unshare will clear the pud pointing to the pmd. If the task in the middle of the page fault is not the last user, the ptep returned by huge_pte_alloc now points to another task's page table or worse. This leads to bad things such as incorrect page map/reference counts or invalid memory references. To fix, expand the use of i_mmap_rwsem as follows: - i_mmap_rwsem is held in read mode whenever huge_pmd_share is called. huge_pmd_share is only called via huge_pte_alloc, so callers of huge_pte_alloc take i_mmap_rwsem before calling. In addition, callers of huge_pte_alloc continue to hold the semaphore until finished with the ptep. - i_mmap_rwsem is held in write mode whenever huge_pmd_unshare is called.

The current implementation doesn't match the description though. It will drain all pcp pages for all zones that happen to have cached pages on the same cpu as the given zone. This will lead to premature pcp cache draining for zones that are not of any interest to the caller - e.g. compaction, hwpoison or memory offline. This forces the page allocator to take locks and potential lock contention as a result. There is no real reason for this sub-optimal implementation. Replace per-cpu work item with a dedicated structure which contains a pointer to the zone and pass it over to the worker. This will get the zone information all the way down to the worker function and do the right job.

This is currently obfuscated by goto retry loop. The code is hard to follow and as a result it is even suboptimal becase each retry round scans the full range from start_pfn even though we have successfully scanned/migrated [start_pfn, pfn] range already. This is all only because check_pages_isolated failure has to rescan the full range again. De-obfuscate the migration retry loop by promoting it to a real for loop. In fact remove the goto altogether by making it a proper double loop (yeah, gotos are nasty in this specific case). In the end we will get a slightly more optimal code which is better readable.

I have been chasing memory offlining not making progress recently. On the way I have noticed few weird decisions in the code. The migration itself is restricted without a reasonable justification and the retry loop around the migration is quite messy. This is addressed by patch 1 and patch 2. Patch 3 is targeting on the faultaround code which has been a hot candidate for the initial issue reported upstream [2] and that I am debugging internally. It turned out to be not the main contributor in the end but I believe we should address it regardless. See the patch description for more details. [1] http://lkml.kernel.org/r/20181120134323.13007-1-mhocko@kernel.org [2] http://lkml.kernel.org/r/20181114070909.GB2653@MiWiFi-R3L-srv This patch (of 3): do_migrate_range has been limiting the number of pages to migrate to 256 for some reason which is not documented. Even if the limit made some sense back then when it was introduced it doesn't really serve a good purpose these days. If the range contains huge pages then we break out of the loop too early and go through LRU and pcp caches draining and scan_movable_pages is quite suboptimal. The only reason to limit the number of pages I can think of is to reduce the potential time to react on the fatal signal. But even then the number of pages is a questionable metric because even a single page migration might block in a non-killable state (e.g. __unmap_and_move). Remove the limit and offline the full requested range (this is one memblock worth of pages with the current code). Should we ever get a report that offlining takes too long to react on fatal signal then we should rather fix the core migration to use killable waits and bailout on a signal.

Their monitoring tool is triggering false alarms on PR_SET_THP_DISABLE tasks because it considers an insufficient THP usage as a memory fragmentation resp. memory pressure issue. Before the said commit each newly created VMA inherited VM_NOHUGEPAGE flag and that got exposed to the userspace via /proc//smaps file. This implementation had its downsides as explained in the commit message but it is true that the userspace doesn't have any means to query for the process wide THP enabled/disabled status. PR_SET_THP_DISABLE is a process wide flag so it makes a lot of sense to export in the process wide context rather than per-vma. Introduce a new field to /proc//status which export this status. If PR_SET_THP_DISABLE is used then it reports false same as when the THP is not compiled in. It doesn't consider the global THP status because we already export that information via sysfs Link: http://lkml.kernel.org/r/20181211143641.3503-4-mhocko@kernel.org Fixes: 1860033237d4 ("mm: make PR_SET_THP_DISABLE immediately active") Signed-off-by: Michal Hocko Acked-by: Vlastimil Babka Reported-by: David Rientjes Cc: Dan Williams Cc: Jan Kara Cc: Mike Rapoport Cc: Paul Oppenheimer Cc: William Kucharski Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds commit 7635d9cbe8327e131a1d3d8517dc186c2796ce2e Author: Michal Hocko Date: Fri Dec 28 00:38:21 2018 -0800 mm, thp, proc: report THP eligibility for each vma Userspace falls short when trying to find out whether a specific memory range is eligible for THP. There are usecases that would like to know that http://lkml.kernel.org/r/alpine.DEB.2.21.1809251248450.50347@chino.kir.corp.google.com : This is used to identify heap mappings that should be able to fault thp : but do not, and they normally point to a low-on-memory or fragmentation : issue. The only way to deduce this now is to query for hg resp. nh flags and confronting the state with the global setting. Except that there is also PR_SET_THP_DISABLE that might change the picture. So the final logic is not trivial. Moreover the eligibility of the vma depends on the type of VMA as well. In the past we have supported only anononymous memory VMAs but things have changed and shmem based vmas are supported as well these days and the query logic gets even more complicated because the eligibility depends on the mount option and another global configuration knob. Simplify the current state and report the THP eligibility in /proc//smaps for each existing vma. Reuse transparent_hugepage_enabled for this purpose. The original implementation of this function assumes that the caller knows that the vma itself is supported for THP so make the core checks into __transparent_hugepage_enabled and use it for existing callers. __show_smap just use the new transparent_hugepage_enabled which also checks the vma support status (please note that this one has to be out of line due to include dependency issues).

This series of three patches aims at making THP eligibility reporting much more robust and long term sustainable. The trigger for the change is a regression report [2] and the long follow up discussion. In short the specific application didn't have good API to query whether a particular mapping can be backed by THP so it has used VMA flags to workaround that. These flags represent a deep internal state of VMAs and as such they should be used by userspace with a great deal of caution. A similar has happened for [3] when users complained that VM_MIXEDMAP is no longer set on DAX mappings. Again a lack of a proper API led to an abuse. The first patch in the series tries to emphasise that that the semantic of flags might change and any application consuming those should be really careful. The remaining two patches provide a more suitable interface to address [2] and provide a consistent API to query the THP status both for each VMA and process wide as well.

And they are important as well because these flags are a deep implementation internal to the MM code and the semantic might change at any time. Let's consider two recent examples: http://lkml.kernel.org/r/20181002100531.GC4135@quack2.suse.cz : commit e1fb4a086495 "dax: remove VM_MIXEDMAP for fsdax and device dax" has : removed VM_MIXEDMAP flag from DAX VMAs. Now our testing shows that in the : mean time certain customer of ours started poking into /proc//smaps : and looks at VMA flags there and if VM_MIXEDMAP is missing among the VMA : flags, the application just fails to start complaining that DAX support is : missing in the kernel. http://lkml.kernel.org/r/alpine.DEB.2.21.1809241054050.224429@chino.kir.corp.google.com : Commit 1860033237d4 ("mm: make PR_SET_THP_DISABLE immediately active") : introduced a regression in that userspace cannot always determine the set : of vmas where thp is ineligible. : Userspace relies on the "nh" flag being emitted as part of /proc/pid/smaps : to determine if a vma is eligible to be backed by hugepages. : Previous to this commit, prctl(PR_SET_THP_DISABLE, 1) would cause thp to : be disabled and emit "nh" as a flag for the corresponding vmas as part of : /proc/pid/smaps. After the commit, thp is disabled by means of an mm : flag and "nh" is not emitted. : This causes smaps parsing libraries to assume a vma is eligible for thp : and ends up puzzling the user on why its memory is not backed by thp. In both cases userspace was relying on a semantic of a specific VMA flag. The primary reason why that happened is a lack of a proper interface. While this has been worked on and it will be fixed properly, it seems that our wording could see some refinement and be more vocal about semantic aspect of these flags as well.

This patchset adds contextual information, why an invalidation is happening, to mmu notifier callback. This is necessary for user of mmu notifier that wish to maintains their own data structure without having to add new fields to struct vm_area_struct (vma). For instance device can have they own page table that mirror the process address space. When a vma is unmap (munmap() syscall) the device driver can free the device page table for the range. Today we do not have any information on why a mmu notifier call back is happening and thus device driver have to assume that it is always an munmap(). This is inefficient at it means that it needs to re-allocate device page table on next page fault and rebuild the whole device driver data structure for the range. Other use case beside munmap() also exist, for instance it is pointless for device driver to invalidate the device page table when the invalidation is for the soft dirtyness tracking. Or device driver can optimize away mprotect() that change the page table permission access for the range. This patchset enables all this optimizations for device drivers. I do not include any of those in this series but another patchset I am posting will leverage this. The patchset is pretty simple from a code point of view. The first two patches consolidate all mmu notifier arguments into a struct so that it is easier to add/change arguments. The last patch adds the contextual information (munmap, protection, soft dirty, clear, ...). This patch (of 3): To avoid having to change many callback definition everytime we want to add a parameter use a structure to group all parameters for the mmu_notifier invalidate_range_start/end callback.

The underlying reason was that the HWPoison page has an elevated reference count and the migration keeps failing. There are two problems with that. First of all it is dubious to migrate the poisoned page because we know that accessing that memory is possible to fail. Secondly it doesn't make any sense to migrate a potentially broken content and preserve the memory corruption over to a new location. Oscar has found out that 4.4 and the current upstream kernels behave slightly differently with his simply testcase === int main(void) { int ret; int i; int fd; char *array = malloc(4096); char *array_locked = malloc(4096); fd = open("/tmp/data", O_RDONLY); read(fd, array, 4095); for (i = 0; i < 4096; i++) array_locked[i] = 'd'; ret = mlock((void *)PAGE_ALIGN((unsigned long)array_locked), sizeof(array_locked)); if (ret) perror("mlock"); sleep (20); ret = madvise((void *)PAGE_ALIGN((unsigned long)array_locked), 4096, MADV_HWPOISON); if (ret) perror("madvise"); for (i = 0; i < 4096; i++) array_locked[i] = 'd'; return 0; } === + offline this memory. In 4.4 kernels he saw the hwpoisoned page to be returned back to the LRU list kernel: [] dump_trace+0x59/0x340 kernel: [] show_stack_log_lvl+0xea/0x170 kernel: [] show_stack+0x21/0x40 kernel: [] dump_stack+0x5c/0x7c kernel: [] warn_slowpath_common+0x81/0xb0 kernel: [] __pagevec_lru_add_fn+0x14c/0x160 kernel: [] pagevec_lru_move_fn+0xad/0x100 kernel: [] __lru_cache_add+0x6c/0xb0 kernel: [] add_to_page_cache_lru+0x46/0x70 kernel: [] extent_readpages+0xc3/0x1a0 [btrfs] kernel: [] __do_page_cache_readahead+0x177/0x200 kernel: [] ondemand_readahead+0x168/0x2a0 kernel: [] generic_file_read_iter+0x41f/0x660 kernel: [] __vfs_read+0xcd/0x140 kernel: [] vfs_read+0x7a/0x120 kernel: [] kernel_read+0x3b/0x50 kernel: [] do_execveat_common.isra.29+0x490/0x6f0 kernel: [] do_execve+0x28/0x30 kernel: [] call_usermodehelper_exec_async+0xfb/0x130 kernel: [] ret_from_fork+0x55/0x80 And that latter confuses the hotremove path because an LRU page is attempted to be migrated and that fails due to an elevated reference count. It is quite possible that the reuse of the HWPoisoned page is some kind of fixed race condition but I am not really sure about that. With the upstream kernel the failure is slightly different. The page doesn't seem to have LRU bit set but isolate_movable_page simply fails and do_migrate_range simply puts all the isolated pages back to LRU and therefore no progress is made and scan_movable_pages finds same set of pages over and over again. Fix both cases by explicitly checking HWPoisoned pages before we even try to get reference on the page, try to unmap it if it is still mapped. As explained by Naoya: : Hwpoison code never unmapped those for no big reason because : Ksm pages never dominate memory, so we simply didn't have strong : motivation to save the pages. Also put WARN_ON(PageLRU) in case there is a race and we can hit LRU HWPoison pages which shouldn't happen but I couldn't convince myself about that. Naoya has noted the following: : Theoretically no such gurantee, because try_to_unmap() doesn't have a : guarantee of success and then memory_failure() returns immediately : when hwpoison_user_mappings fails. : Or the following code (comes after hwpoison_user_mappings block) also impli= : es : that the target page can still have PageLRU flag. : : /* : * Torn down by someone else? : */ : if (PageLRU(p) && !PageSwapCache(p) && p->mapping =3D=3D NULL) { : action_result(pfn, MF_MSG_TRUNCATED_LRU, MF_IGNORED); : res =3D -EBUSY; : goto out; : } : : So I think it's OK to keep "if (WARN_ON(PageLRU(page)))" block in : current version of your patch.

This resulted in a minor bug in the arm64 implementation, giving rise to spurious VM_WARN messages. This patch moves the pXd_present() checks out into the core code, refactoring the callsites at the same time so that we avoid the complex conjunctions when determining whether or not we can put down a huge mapping.

Background writeback is mostly concerned with cleaning a certain number of dirty pages based on various mm heuristics. It may not write the full set of dirty pages or wait for I/O to complete. Integrity writeback is responsible for persisting a set of dirty pages before the writeback job completes. For example, an fsync() call must perform integrity writeback to ensure data is on disk before the call returns. write_cache_pages() unconditionally breaks out of its processing loop in the event of a ->writepage() error. This is fine for background writeback, which had no strict requirements and will eventually come around again. This can cause problems for integrity writeback on filesystems that might need to clean up state associated with failed page writeouts. For example, XFS performs internal delayed allocation accounting before returning a ->writepage() error, where applicable. If the current writeback happens to be associated with an unmount and write_cache_pages() completes the writeback prematurely due to error, the filesystem is unmounted in an inconsistent state if dirty+delalloc pages still exist. To handle this problem, update write_cache_pages() to always process the full set of pages for integrity writeback regardless of ->writepage() errors. Save the first encountered error and return it to the caller once complete. This facilitates XFS (or any other fs that expects integrity writeback to process the entire set of dirty pages) to clean up its internal state completely in the event of persistent mapping errors. Background writeback continues to exit on the first error encountered.

Currently the online_pages phase is protected by the global locks (device_device_hotplug_lock and mem_hotplug_lock), which ensures there is no contention during the update of nr_zones. These global locks introduces scalability issues (especially the second one), which slow down code relying on get_online_mems(). This is also a preparation for not having to rely on get_online_mems() but instead some more fine grained locks. The patch moves init_currently_empty_zone under both zone_span_writelock and pgdat_resize_lock because both the pgdat state is changed (nr_zones) and the zone's start_pfn. Also this patch changes the documentation of node_size_lock to include the protection of nr_zones.

To overcome the problem, admin needs to design write limitation to guarantee flash health for entire product life. This patch creates a new knob "writeback_limit" for zram. writeback_limit's default value is 0 so that it doesn't limit any writeback. If admin want to measure writeback count in a certain period, he could know it via /sys/block/zram0/bd_stat's 3rd column. If admin want to limit writeback as per-day 400M, he could do it like below. MB_SHIFT=20 4K_SHIFT=12 echo $((400<>4K_SHIFT)) > \ /sys/block/zram0/writeback_limit. If admin want to allow further write again, he could do it like below echo 0 > /sys/block/zram0/writeback_limit If admin want to see remaining writeback budget, cat /sys/block/zram0/writeback_limit The writeback_limit count will reset whenever you reset zram (e.g., system reboot, echo 1 > /sys/block/zramX/reset) so keeping how many of writeback happened until you reset the zram to allocate extra writeback budget in next setting is user's job.

In the zram-swap use case, zram usually has many idle/huge swap pages. It's pointless to keep them in memory (ie, zram). To solve this problem, this feature introduces idle/huge page writeback to the backing device so the goal is to save more memory space on embedded systems. Normal sequence to use idle/huge page writeback feature is as follows, while (1) { # mark allocated zram slot to idle echo all > /sys/block/zram0/idle # leave system working for several hours # Unless there is no access for some blocks on zram, # they are still IDLE marked pages. echo "idle" > /sys/block/zram0/writeback or/and echo "huge" > /sys/block/zram0/writeback # write the IDLE or/and huge marked slot into backing device # and free the memory. } Per the discussion at https://lore.kernel.org/lkml/20181122065926.GG3441@jagdpanzerIV/T/#u, This patch removes direct incommpressibe page writeback feature (d2afd25114f4 ("zram: write incompressible pages to backing device")). Below concerns from Sergey: == &< == "IDLE writeback" is superior to "incompressible writeback". "incompressible writeback" is completely unpredictable and uncontrollable; it depens on data patterns and compression algorithms. While "IDLE writeback" is predictable. I even suspect, that, *ideally*, we can remove "incompressible writeback". "IDLE pages" is a super set which also includes "incompressible" pages. So, technically, we still can do "incompressible writeback" from "IDLE writeback" path; but a much more reasonable one, based on a page idling period. I understand that you want to keep "direct incompressible writeback" around. ZRAM is especially popular on devices which do suffer from flash wearout, so I can see "incompressible writeback" path becoming a dead code, long term. == &< == Below concerns from Minchan: == &< == My concern is if we enable CONFIG_ZRAM_WRITEBACK in this implementation, both hugepage/idlepage writeck will turn on. However someuser want to enable only idlepage writeback so we need to introduce turn on/off knob for hugepage or new CONFIG_ZRAM_IDLEPAGE_WRITEBACK for those usecase. I don't want to make it complicated *if possible*. Long term, I imagine we need to make VM aware of new swap hierarchy a little bit different with as-is. For example, first high priority swap can return -EIO or -ENOCOMP, swap try to fallback to next lower priority swap device. With that, hugepage writeback will work tranparently. So we could regard it as regression because incompressible pages doesn't go to backing storage automatically. Instead, user should do it via "echo huge" > /sys/block/zram/writeback" manually. == &< == Link: http://lkml.kernel.org/r/20181127055429.251614-6-minchan@kernel.org Signed-off-by: Minchan Kim Reviewed-by: Joey Pabalinas Reviewed-by: Sergey Senozhatsky Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds commit e82592c4fd7eafe8dec12a70436e93e3afb28556 Author: Minchan Kim Date: Fri Dec 28 00:36:44 2018 -0800 zram: introduce ZRAM_IDLE flag To support idle page writeback with upcoming patches, this patch introduces a new ZRAM_IDLE flag.

It might fail to find a empty slot if serious contention happens. However, it's not severe problem because huge page writeback has already possiblity to fail if there is severe memory pressure. Worst case is just keeping the incompressible in memory, not storage. The other problem is zram_slot_lock in zram_slot_slot_free_notify. To make it safe is this patch introduces zram_slot_trylock where zram_slot_free_notify uses it. Although it's rare to be contented, this patch adds new debug stat "miss_free" to keep monitoring how often it happens.

Currently, we only call release_mem_region_adjustable() in __remove_pages if the zone is not ZONE_DEVICE, because resources that belong to HMM/devm are being released by themselves with devm_release_mem_region. Since we do not want to touch any zone/page stuff during the removing of the memory (but during the offlining), we do not want to check for the zone here. So we need another way to tell release_mem_region_adjustable() to not realease the resource in case it belongs to HMM/devm. HMM/devm acquires/releases a resource through devm_request_mem_region/devm_release_mem_region. These resources have the flag IORESOURCE_MEM, while resources acquired by hot-add memory path (register_memory_resource()) contain IORESOURCE_SYSTEM_RAM. So, we can check for this flag in release_mem_region_adjustable, and if the resource does not contain such flag, we know that we are dealing with a HMM/devm resource, so we can back off.

BTW, comparing PAGES_PER_SECTION with node_spanned_pages is not correct, since nr_initialised is zone based instead of node based. Even node_spanned_pages is bigger than PAGES_PER_SECTION, its highest zone would have pages less than PAGES_PER_SECTION.

And that failure is retried nine times, amplifying the pain when trying to migrate a popular page. With a single persistent faulter, migration sometimes succeeds; with two or three concurrent faulters, success becomes much less likely (and the more the page was mapped, the worse the overhead of unmapping and remapping it on each try). This is especially a problem for memory offlining, where the outer level retries forever (or until terminated from userspace), because a heavy refault workload can trigger an endless loop of migration failures. wait_on_page_locked() is the wrong tool for the job. David Herrmann (but was he the first?) noticed this issue in 2014: https://marc.info/?l=linux-mm&m=140110465608116&w=2 Tim Chen started a thread in August 2017 which appears relevant: https://marc.info/?l=linux-mm&m=150275941014915&w=2 where Kan Liang went on to implicate __migration_entry_wait(): https://marc.info/?l=linux-mm&m=150300268411980&w=2 and the thread ended up with the v4.14 commits: 2554db916586 ("sched/wait: Break up long wake list walk") 11a19c7b099f ("sched/wait: Introduce wakeup boomark in wake_up_page_bit") Baoquan He reported "Memory hotplug softlock issue" 14 November 2018: https://marc.info/?l=linux-mm&m=154217936431300&w=2 We have all assumed that it is essential to hold a page reference while waiting on a page lock: partly to guarantee that there is still a struct page when MEMORY_HOTREMOVE is configured, but also to protect against reuse of the struct page going to someone who then holds the page locked indefinitely, when the waiter can reasonably expect timely unlocking. But in fact, so long as wait_on_page_bit_common() does the put_page(), and is careful not to rely on struct page contents thereafter, there is no need to hold a reference to the page while waiting on it. That does mean that this case cannot go back through the loop: but that's fine for the page migration case, and even if used more widely, is limited by the "Stop walking if it's locked" optimization in wake_page_function(). Add interface put_and_wait_on_page_locked() to do this, using "behavior" enum in place of "lock" arg to wait_on_page_bit_common() to implement it. No interruptible or killable variant needed yet, but they might follow: I have a vague notion that reporting -EINTR should take precedence over return from wait_on_page_bit_common() without knowing the page state, so arrange it accordingly - but that may be nothing but pedantic. __migration_entry_wait() still has to take a brief reference to the page, prior to calling put_and_wait_on_page_locked(): but now that it is dropped before waiting, the chance of impeding page migration is very much reduced. Should we perhaps disable preemption across this? shrink_page_list()'s __ClearPageLocked(): that was a surprise! This survived a lot of testing before that showed up. PageWaiters may have been set by wait_on_page_bit_common(), and the reference dropped, just before shrink_page_list() succeeds in freezing its last page reference: in such a case, unlock_page() must be used. Follow the suggestion from Michal Hocko, just revert a978d6f52106 ("mm: unlockless reclaim") now: that optimization predates PageWaiters, and won't buy much these days; but we can reinstate it for the !PageWaiters case if anyone notices. It does raise the question: should vmscan.c's is_page_cache_freeable() and __remove_mapping() now treat a PageWaiters page as if an extra reference were held? Perhaps, but I don't think it matters much, since shrink_page_list() already had to win its trylock_page(), so waiters are not very common there: I noticed no difference when trying the bigger change, and it's surely not needed while put_and_wait_on_page_locked() is only used for page migration.

If the fallback_order is smaller than a pageblock order (order-9 on 64-bit x86) then it's considered an event that will cause external fragmentation issues in the future. The kernel reduces the probability of such events by increasing the watermark sizes by calling set_recommended_min_free_kbytes early in the lifetime of the system. This works reasonably well in general but if there are enough sparsely populated pageblocks then the problem can still occur as enough memory is free overall and kswapd stays asleep. This patch introduces a watermark_boost_factor sysctl that allows a zone watermark to be temporarily boosted when an external fragmentation causing events occurs. The boosting will stall allocations that would decrease free memory below the boosted low watermark and kswapd is woken if the calling context allows to reclaim an amount of memory relative to the size of the high watermark and the watermark_boost_factor until the boost is cleared. When kswapd finishes, it wakes kcompactd at the pageblock order to clean some of the pageblocks that may have been affected by the fragmentation event. kswapd avoids any writeback, slab shrinkage and swap from reclaim context during this operation to avoid excessive system disruption in the name of fragmentation avoidance. Care is taken so that kswapd will do normal reclaim work if the system is really low on memory. This was evaluated using the same workloads as "mm, page_alloc: Spread allocations across zones before introducing fragmentation". 1-socket Skylake machine config-global-dhp__workload_thpfioscale XFS (no special madvise) 4 fio threads, 1 THP allocating thread -------------------------------------- 4.20-rc3 extfrag events < order 9: 804694 4.20-rc3+patch: 408912 (49% reduction) 4.20-rc3+patch1-4: 18421 (98% reduction) 4.20.0-rc3 4.20.0-rc3 lowzone-v5r8 boost-v5r8 Amean fault-base-1 653.58 ( 0.00%) 652.71 ( 0.13%) Amean fault-huge-1 0.00 ( 0.00%) 178.93 * -99.00%* 4.20.0-rc3 4.20.0-rc3 lowzone-v5r8 boost-v5r8 Percentage huge-1 0.00 ( 0.00%) 5.12 ( 100.00%) Note that external fragmentation causing events are massively reduced by this path whether in comparison to the previous kernel or the vanilla kernel.

It has been noted before that fragmentation avoidance (aka anti-fragmentation) is not perfect. Given sufficient time or an adverse workload, memory gets fragmented and the long-term success of high-order allocations degrades. This series defines an adverse workload, a definition of external fragmentation events (including serious) ones and a series that reduces the level of those fragmentation events. The details of the workload and the consequences are described in more detail in the changelogs. However, from patch 1, this is a high-level summary of the adverse workload. The exact details are found in the mmtests implementation. The broad details of the workload are as follows; 1. Create an XFS filesystem (not specified in the configuration but done as part of the testing for this patch) 2. Start 4 fio threads that write a number of 64K files inefficiently. Inefficiently means that files are created on first access and not created in advance (fio parameterr create_on_open=1) and fallocate is not used (fallocate=none). With multiple IO issuers this creates a mix of slab and page cache allocations over time. The total size of the files is 150% physical memory so that the slabs and page cache pages get mixed 3. Warm up a number of fio read-only threads accessing the same files created in step 2. This part runs for the same length of time it took to create the files. It'll fault back in old data and further interleave slab and page cache allocations. As it's now low on memory due to step 2, fragmentation occurs as pageblocks get stolen. 4. While step 3 is still running, start a process that tries to allocate 75% of memory as huge pages with a number of threads. The number of threads is based on a (NR_CPUS_SOCKET - NR_FIO_THREADS)/4 to avoid THP threads contending with fio, any other threads or forcing cross-NUMA scheduling. Note that the test has not been used on a machine with less than 8 cores. The benchmark records whether huge pages were allocated and what the fault latency was in microseconds 5. Measure the number of events potentially causing external fragmentation, the fault latency and the huge page allocation success rate. 6. Cleanup Overall the series reduces external fragmentation causing events by over 94% on 1 and 2 socket machines, which in turn impacts high-order allocation success rates over the long term. There are differences in latencies and high-order allocation success rates. Latencies are a mixed bag as they are vulnerable to exact system state and whether allocations succeeded so they are treated as a secondary metric. Patch 1 uses lower zones if they are populated and have free memory instead of fragmenting a higher zone. It's special cased to handle a Normal->DMA32 fallback with the reasons explained in the changelog. Patch 2-4 boosts watermarks temporarily when an external fragmentation event occurs. kswapd wakes to reclaim a small amount of old memory and then wakes kcompactd on completion to recover the system slightly. This introduces some overhead in the slowpath. The level of boosting can be tuned or disabled depending on the tolerance for fragmentation vs allocation latency. Patch 5 stalls some movable allocation requests to let kswapd from patch 4 make some progress. The duration of the stalls is very low but it is possible to tune the system to avoid fragmentation events if larger stalls can be tolerated. The bulk of the improvement in fragmentation avoidance is from patches 1-4 but patch 5 can deal with a rare corner case and provides the option of tuning a system for THP allocation success rates in exchange for some stalls to control fragmentation. This patch (of 5): The page allocator zone lists are iterated based on the watermarks of each zone which does not take anti-fragmentation into account. On x86, node 0 may have multiple zones while other nodes have one zone. A consequence is that tasks running on node 0 may fragment ZONE_NORMAL even though ZONE_DMA32 has plenty of free memory. This patch special cases the allocator fast path such that it'll try an allocation from a lower local zone before fragmenting a higher zone. In this case, stealing of pageblocks or orders larger than a pageblock are still allowed in the fast path as they are uninteresting from a fragmentation point of view. This was evaluated using a benchmark designed to fragment memory before attempting THP allocations. It's implemented in mmtests as the following configurations configs/config-global-dhp__workload_thpfioscale configs/config-global-dhp__workload_thpfioscale-defrag configs/config-global-dhp__workload_thpfioscale-madvhugepage e.g. from mmtests ./run-mmtests.sh --run-monitor --config configs/config-global-dhp__workload_thpfioscale test-run-1 The broad details of the workload are as follows; 1. Create an XFS filesystem (not specified in the configuration but done as part of the testing for this patch). 2. Start 4 fio threads that write a number of 64K files inefficiently. Inefficiently means that files are created on first access and not created in advance (fio parameter create_on_open=1) and fallocate is not used (fallocate=none). With multiple IO issuers this creates a mix of slab and page cache allocations over time. The total size of the files is 150% physical memory so that the slabs and page cache pages get mixed. 3. Warm up a number of fio read-only processes accessing the same files created in step 2. This part runs for the same length of time it took to create the files. It'll refault old data and further interleave slab and page cache allocations. As it's now low on memory due to step 2, fragmentation occurs as pageblocks get stolen. 4. While step 3 is still running, start a process that tries to allocate 75% of memory as huge pages with a number of threads. The number of threads is based on a (NR_CPUS_SOCKET - NR_FIO_THREADS)/4 to avoid THP threads contending with fio, any other threads or forcing cross-NUMA scheduling. Note that the test has not been used on a machine with less than 8 cores. The benchmark records whether huge pages were allocated and what the fault latency was in microseconds. 5. Measure the number of events potentially causing external fragmentation, the fault latency and the huge page allocation success rate. 6. Cleanup the test files. Note that due to the use of IO and page cache that this benchmark is not suitable for running on large machines where the time to fragment memory may be excessive. Also note that while this is one mix that generates fragmentation that it's not the only mix that generates fragmentation. Differences in workload that are more slab-intensive or whether SLUB is used with high-order pages may yield different results. When the page allocator fragments memory, it records the event using the mm_page_alloc_extfrag ftrace event. If the fallback_order is smaller than a pageblock order (order-9 on 64-bit x86) then it's considered to be an "external fragmentation event" that may cause issues in the future. Hence, the primary metric here is the number of external fragmentation events that occur with order < 9. The secondary metric is allocation latency and huge page allocation success rates but note that differences in latencies and what the success rate also can affect the number of external fragmentation event which is why it's a secondary metric. 1-socket Skylake machine config-global-dhp__workload_thpfioscale XFS (no special madvise) 4 fio threads, 1 THP allocating thread -------------------------------------- 4.20-rc3 extfrag events < order 9: 804694 4.20-rc3+patch: 408912 (49% reduction) thpfioscale Fault Latencies 4.20.0-rc3 4.20.0-rc3 vanilla lowzone-v5r8 Amean fault-base-1 662.92 ( 0.00%) 653.58 * 1.41%* Amean fault-huge-1 0.00 ( 0.00%) 0.00 ( 0.00%) 4.20.0-rc3 4.20.0-rc3 vanilla lowzone-v5r8 Percentage huge-1 0.00 ( 0.00%) 0.00 ( 0.00%) Fault latencies are slightly reduced while allocation success rates remain at zero as this configuration does not make any special effort to allocate THP and fio is heavily active at the time and either filling memory or keeping pages resident. However, a 49% reduction of serious fragmentation events reduces the changes of external fragmentation being a problem in the future. Vlastimil asked during review for a breakdown of the allocation types that are falling back. vanilla 3816 MIGRATE_UNMOVABLE 800845 MIGRATE_MOVABLE 33 MIGRATE_UNRECLAIMABLE patch 735 MIGRATE_UNMOVABLE 408135 MIGRATE_MOVABLE 42 MIGRATE_UNRECLAIMABLE The majority of the fallbacks are due to movable allocations and this is consistent for the workload throughout the series so will not be presented again as the primary source of fallbacks are movable allocations. Movable fallbacks are sometimes considered "ok" to fallback because they can be migrated. The problem is that they can fill an unmovable/reclaimable pageblock causing those allocations to fallback later and polluting pageblocks with pages that cannot move. If there is a movable fallback, it is pretty much guaranteed to affect an unmovable/reclaimable pageblock and while it might not be enough to actually cause a unmovable/reclaimable fallback in the future, we cannot know that in advance so the patch takes the only option available to it. Hence, it's important to control them. This point is also consistent throughout the series and will not be repeated. 1-socket Skylake machine global-dhp__workload_thpfioscale-madvhugepage-xfs (MADV_HUGEPAGE) ----------------------------------------------------------------- 4.20-rc3 extfrag events < order 9: 291392 4.20-rc3+patch: 191187 (34% reduction) thpfioscale Fault Latencies 4.20.0-rc3 4.20.0-rc3 vanilla lowzone-v5r8 Amean fault-base-1 1495.14 ( 0.00%) 1467.55 ( 1.85%) Amean fault-huge-1 1098.48 ( 0.00%) 1127.11 ( -2.61%) thpfioscale Percentage Faults Huge 4.20.0-rc3 4.20.0-rc3 vanilla lowzone-v5r8 Percentage huge-1 78.57 ( 0.00%) 77.64 ( -1.18%) Fragmentation events were reduced quite a bit although this is known to be a little variable.

The allocation success rate is high enough that the system is struggling and there is quite a lot of parallel reclaim and compaction activity. There is also a certain degree of luck on whether processes start on node 0 or not for this patch but the relevance is reduced later in the series. Overall, the patch reduces the number of external fragmentation causing events so the success of THP over long periods of time would be improved for this adverse workload.

This is OK for high order page, but for order-0 pages, it misses the optimization opportunity of using Per-Cpu-Pages and can cause zone lock contention when called frequently. Pawel Staszewski recently shared his result of 'how Linux kernel handles normal traffic'[1] and from perf data, Jesper Dangaard Brouer found the lock contention comes from page allocator: mlx5e_poll_tx_cq | --16.34%--napi_consume_skb | |--12.65%--__free_pages_ok | | | --11.86%--free_one_page | | | |--10.10%--queued_spin_lock_slowpath | | | --0.65%--_raw_spin_lock | |--1.55%--page_frag_free | --1.44%--skb_release_data Jesper explained how it happened: mlx5 driver RX-page recycle mechanism is not effective in this workload and pages have to go through the page allocator. The lock contention happens during mlx5 DMA TX completion cycle. And the page allocator cannot keep up at these speeds.[2] I thought that __free_pages_ok() are mostly freeing high order pages and thought this is an lock contention for high order pages but Jesper explained in detail that __free_pages_ok() here are actually freeing order-0 pages because mlx5 is using order-0 pages to satisfy its page pool allocation request.[3] The free path as pointed out by Jesper is: skb_free_head() -> skb_free_frag() -> page_frag_free() And the pages being freed on this path are order-0 pages. Fix this by doing similar things as in __page_frag_cache_drain() - send the being freed page to PCP if it's an order-0 page, or directly to Buddy if it is a high order page. With this change, Paweł hasn't noticed lock contention yet in his workload and Jesper has noticed a 7% performance improvement using a micro benchmark and lock contention is gone. Ilias' test on a 'low' speed 1Gbit interface on an cortex-a53 shows ~11% performance boost testing with 64byte packets and __free_pages_ok() disappeared from perf top.

The motivation was considerations for when EXPORT_SYMBOL_GPL is warranted and the criteria for taking the exceptional step of reclassifying an existing export. Specifically, I wanted to make the case that although the line is fuzzy and hard to specify in abstract terms, it is nonetheless clear that devm_memremap_pages() and HMM (Heterogeneous Memory Management) have crossed it. The devm_memremap_pages() facility should have been EXPORT_SYMBOL_GPL from the beginning, and HMM as a derivative of that functionality should have naturally picked up that designation as well. Contrary to typical rules, the HMM infrastructure was merged upstream with zero in-tree consumers. There was a promise at the time that those users would be merged "soon", but it has been over a year with no drivers arriving. While the Nouveau driver is about to belatedly make good on that promise it is clear that HMM was targeted first and foremost at an out-of-tree consumer. HMM is derived from devm_memremap_pages(), a facility Christoph and I spearheaded to support persistent memory. It combines a device lifetime model with a dynamically created 'struct page' / memmap array for any physical address range. It enables coordination and control of the many code paths in the kernel built to interact with memory via 'struct page' objects. With HMM the integration goes even deeper by allowing device drivers to hook and manipulate page fault and page free events. One interpretation of when EXPORT_SYMBOL is suitable is when it is exporting stable and generic leaf functionality. The devm_memremap_pages() facility continues to see expanding use cases, peer-to-peer DMA being the most recent, with no clear end date when it will stop attracting reworks and semantic changes. It is not suitable to export devm_memremap_pages() as a stable 3rd party driver API due to the fact that it is still changing and manipulates core behavior. Moreover, it is not in the best interest of the long term development of the core memory management subsystem to permit any external driver to effectively define its own system-wide memory management policies with no encouragement to engage with upstream. I am also concerned that HMM was designed in a way to minimize further engagement with the core-MM. That, with these hooks in place, device-drivers are free to implement their own policies without much consideration for whether and how the core-MM could grow to meet that need. Going forward not only should HMM be EXPORT_SYMBOL_GPL, but the core-MM should be allowed the opportunity and stimulus to change and address these new use cases as first class functionality. Original changelog: hmm_devmem_add(), and hmm_devmem_add_resource() duplicated devm_memremap_pages() and are now simple now wrappers around the core facility to inject a dev_pagemap instance into the global pgmap_radix and hook page-idle events. The devm_memremap_pages() interface is base infrastructure for HMM. HMM has more and deeper ties into the kernel memory management implementation than base ZONE_DEVICE which is itself a EXPORT_SYMBOL_GPL facility. Originally, the HMM page structure creation routines copied the devm_memremap_pages() code and reused ZONE_DEVICE. A cleanup to unify the implementations was discussed during the initial review: http://lkml.iu.edu/hypermail/linux/kernel/1701.2/00812.html Recent work to extend devm_memremap_pages() for the peer-to-peer-DMA facility enabled this cleanup to move forward. In addition to the integration with devm_memremap_pages() HMM depends on other GPL-only symbols: mmu_notifier_unregister_no_release percpu_ref region_intersects __class_create It goes further to consume / indirectly expose functionality that is not exported to any other driver: alloc_pages_vma walk_page_range HMM is derived from devm_memremap_pages(), and extends deep core-kernel fundamentals. Similar to devm_memremap_pages(), mark its entry points EXPORT_SYMBOL_GPL().

However, the result from devm_add_action() is not checked. Checking the error from devm_add_action() is not enough. The api currently relies on the fact that the percpu_ref it is using is killed by the time the devm_memremap_pages_release() is run. Rather than continue this awkward situation, offload the responsibility of killing the percpu_ref to devm_memremap_pages_release() directly. This allows devm_memremap_pages() to do the right thing relative to init failures and shutdown. Without this change we could fail to register the teardown of devm_memremap_pages(). The likelihood of hitting this failure is tiny as small memory allocations almost always succeed. However, the impact of the failure is large given any future reconfiguration, or disable/enable, of an nvdimm namespace will fail forever as subsequent calls to devm_memremap_pages() will fail to setup the pgmap_radix since there will be stale entries for the physical address range. An argument could be made to require that the ->kill() operation be set in the @pgmap arg rather than passed in separately. However, it helps code readability, tracking the lifetime of a given instance, to be able to grep the kill routine directly at the devm_memremap_pages() call site.

Specifically the facility is tightly integrated with the kernel's memory hotplug functionality. It injects an altmap argument deep into the architecture specific vmemmap implementation to allow allocating from specific reserved pages, and it has Linux specific assumptions about page structure reference counting relative to get_user_pages() and get_user_pages_fast(). It was an oversight and a mistake that this was not marked EXPORT_SYMBOL_GPL from the outset. Again, devm_memremap_pagex() exposes and relies upon core kernel internal assumptions and will continue to evolve along with 'struct page', memory hotplug, and support for new memory types / topologies. Only an in-kernel GPL-only driver is expected to keep up with this ongoing evolution. This interface, and functionality derived from this interface, is not suitable for kernel-external drivers.

This made swap_info_struct size increased to 40KiB and needs an order-4 page to hold it. This is not optimal in that: 1 Most systems have way less than MAX_NUMNODES(1024) nodes so it is a waste of memory; 2 It could cause swapon failure if the swap device is swapped on after system has been running for a while, due to no order-4 page is available as pointed out by Vasily Averin. Solve the above two issues by using nr_node_ids(which is the actual possible node number the running system has) for avail_lists instead of MAX_NUMNODES. nr_node_ids is unknown at compile time so can't be directly used when declaring this array. What I did here is to declare avail_lists as zero element array and allocate space for it when allocating space for swap_info_struct. The reason why keep using array but not pointer is plist_for_each_entry needs the field to be part of the struct, so pointer will not work. This patch is on top of Vasily Averin's fix commit. I think the use of kvzalloc for swap_info_struct is still needed in case nr_node_ids is really big on some systems.

It is also reasonable to expect that cpu_to_node will provide a sane value and there might be many more callers like that. The second problem is that __register_one_node relies on cpu_to_node to properly associate cpus back to the node when it is onlined.

The original idea behind dumping the page state for all call paths was that these messages will be helpful debugging failures. From the above it seems that this is not the case for the CMA path because we are lacking much more context. E.g the second reported page might be a CMA allocated page. It is still interesting to see a slab page in the CMA area but it is hard to tell whether this is bug from the above output alone. Address this issue by dumping the page state only on request. Both start_isolate_page_range and has_unmovable_pages already have an argument to ignore hwpoison pages so make this argument more generic and turn it into flags and allow callers to combine non-default modes into a mask. While we are at it, has_unmovable_pages call from is_pageblock_removable_nolock (sysfs removable file) is questionable to report the failure so drop it from there as well.

If the migration failes then it would be really helpful to see which page that and its state. The same applies to the isolation phase. If we fail to isolate a page from the allocator then knowing the state of the page would be helpful as well. Dump the page state that fails to get isolated or migrated.

On the other hand the function is called also from contexts which just want to inform about the page state and those would rather not disrupt logs that much (e.g. some systems route these messages to the normal console). Reduce the loglevel to KERN_WARNING to make dump_page easier to reuse for other contexts while those messages will still make it to the kernel log in most setups. Even if the loglevel setup filters warnings away those paths that are really critical already print the more targeted error or panic and that should make it to the kernel log.

As things stand now we get only very limited information in the kernel log when the offlining fails. It is usually only [ 1984.506184] rac1 kernel: memory offlining [mem 0x82600000000-0x8267fffffff] failed with no further details. We do not know what exactly fails and for what reason. Whenever I was forced to debug such a failure I've always had to do a debugging patch to tell me more. We can enable some tracepoints but it would be much better to get a better picture without using them. This patch series does 2 things. The first one is to make dump_page more usable by printing more information about the mapping patch 1. Then it reduces the log level from emerg to warning so that this function is usable from less critical context patch 2. Then I have added more detailed information about the offlining failure patch 4 and finally add dump_page to isolation and offlining migration paths. Patch 3 is a trivial cleanup. This patch (of 6): __dump_page prints the mapping pointer but that is quite unhelpful for many reports because the pointer itself only helps to distinguish anon/ksm mappings from other ones (because of lowest bits set). Sometimes it would be much more helpful to know what kind of mapping that is actually and if we know this is a file mapping then also try to resolve the dentry name.

David Laight provided a nice comparison of disassembly of multiple variants, which shows that the current version produces a 4 deep dependency chain, and fixing the sparse warning by changing logical and to multiplication emits an IMUL, making it even more expensive. The code as rewritten by this patch yielded the best disassembly, with a single predictable branch for the most common case, and a ternary operator for the rest, which gcc seems to compile without a branch or cmov by itself. The result should be more readable, without a sparse warning and probably also faster for the common case.

After mount, local alloc not empty, then reserver cluster didn't alloc a new local alloc window, reserveration map is empty(ocfs2_reservation_map.m_bitmap_len = 0), that triggered the following panic. This issue was reported at https://oss.oracle.com/pipermail/ocfs2-devel/2015-May/010854.html and was advised to fixed during mount. But this is a very unusual inconsistent state, usually journal dirty flag should be cleared at the last stage of umount until every other things go right. We may need do further debug to check that. Any way to avoid possible futher corruption, mount should be abort and fsck should be run.

Say if we compile ocfs2 module as following. cp -r /kernel/tree/fs/ocfs2 /other/dir/ocfs2 cd /other/dir/ocfs2 make -C /path/to/kernel_source M=`pwd` modules Acutally, the compiler wil try to find included file in /kernel/tree/fs/ocfs2, rather than the directory /other/dir/ocfs2. To fix this little bug, we introduce the var $(src) provided by kbuild. $(src) means the absolute path of the running kbuild file.

As the results, systems have 60+ CPUs with both timer and workqueue objects enabled could trigger "ODEBUG: Out of memory. ODEBUG disabled". Some debug objects are allocated during the early boot. Enabling some options like timers or workqueue objects may increase the size required significantly with large number of CPUs. For example, CONFIG_DEBUG_OBJECTS_TIMERS: No. CPUs x 2 (worker pool) objects: start_kernel workqueue_init_early init_worker_pool init_timer_key debug_object_init plus No. CPUs objects (CONFIG_HIGH_RES_TIMERS): sched_init hrtick_rq_init hrtimer_init CONFIG_DEBUG_OBJECTS_WORK: No. CPUs objects: vmalloc_init __init_work plus No. CPUs x 6 (workqueue) objects: workqueue_init_early alloc_workqueue __alloc_workqueue_key alloc_and_link_pwqs init_pwq Also, plus No. CPUs objects: perf_event_init __init_srcu_struct init_srcu_struct_fields init_srcu_struct_nodes __init_work However, none of the things are actually used or required before debug_objects_mem_init() is invoked, so just move the call right before vmalloc_init(). According to tglx, "the reason why the call is at this place in start_kernel() is historical. It's because back in the days when debugobjects were added the memory allocator was enabled way later than today."

The script tests a regular text file (Makefile) for basic sanity checks and then runs it on a binary file (Documentation/logo.gif) to make sure it works in both cases. It also tests opening files passed on the command line as well as piped files read from standard input. Finally a run on the complete tree will be performed to catch any other potential issues.

When page_address is used to get pointer to memory that corresponds to some page, the tag of the resulting pointer gets set to 0xff, even though the allocated memory might have been tagged differently. For slab pages it's impossible to recover the correct tag to return from page_address, since the page might contain multiple slab objects tagged with different values, and we can't know in advance which one of them is going to get accessed. For non slab pages however, we can recover the tag in page_address, since the whole page was marked with the same tag. This patch adds tagging to non slab memory allocated with pagealloc. To set the tag of the pointer returned from page_address, the tag gets stored to page->flags when the memory gets allocated.

When a new slab cache is created, tag-based KASAN rounds up the size of the objects in this cache to KASAN_SHADOW_SCALE_SIZE (== 16). 2. On each kmalloc tag-based KASAN generates a random tag, sets the shadow memory, that corresponds to this object to this tag, and embeds this tag value into the top byte of the returned pointer. 3. On each kfree tag-based KASAN poisons the shadow memory with a random tag to allow detection of use-after-free bugs. The rest of the logic of the hook implementation is very much similar to the one provided by generic KASAN. Tag-based KASAN saves allocation and free stack metadata to the slab object the same way generic KASAN does.

Instead we compute the tag twice, once when a slab is created before calling the constructor and then again each time when an object is allocated with kmalloc. Tag is computed simply by taking the lowest byte of the index that corresponds to the object. However in kasan_kmalloc we only have access to the objects pointer, so we need a way to find out which index this object corresponds to. This patch moves obj_to_index from slab.c to include/linux/slab_def.h to be reused by KASAN.

Since the object address might be tagged, we need to assign a tag before calling constructor.

The downside is that such object would always have the same tag when it is reallocated, so we won't catch use-after-frees on it. Also pressign tags for objects from SLAB_TYPESAFE_BY_RCU caches, since they can be validy accessed after having been freed.

This patchset adds a new software tag-based mode to KASAN [1]. (Initially this mode was called KHWASAN, but it got renamed, see the naming rationale at the end of this section). The plan is to implement HWASan [2] for the kernel with the incentive, that it's going to have comparable to KASAN performance, but in the same time consume much less memory, trading that off for somewhat imprecise bug detection and being supported only for arm64. The underlying ideas of the approach used by software tag-based KASAN are: 1. By using the Top Byte Ignore (TBI) arm64 CPU feature, we can store pointer tags in the top byte of each kernel pointer. 2. Using shadow memory, we can store memory tags for each chunk of kernel memory. 3. On each memory allocation, we can generate a random tag, embed it into the returned pointer and set the memory tags that correspond to this chunk of memory to the same value. 4. By using compiler instrumentation, before each memory access we can add a check that the pointer tag matches the tag of the memory that is being accessed. 5. On a tag mismatch we report an error. With this patchset the existing KASAN mode gets renamed to generic KASAN, with the word "generic" meaning that the implementation can be supported by any architecture as it is purely software. The new mode this patchset adds is called software tag-based KASAN. The word "tag-based" refers to the fact that this mode uses tags embedded into the top byte of kernel pointers and the TBI arm64 CPU feature that allows to dereference such pointers. The word "software" here means that shadow memory manipulation and tag checking on pointer dereference is done in software. As it is the only tag-based implementation right now, "software tag-based" KASAN is sometimes referred to as simply "tag-based" in this patchset. A potential expansion of this mode is a hardware tag-based mode, which would use hardware memory tagging support (announced by Arm [3]) instead of compiler instrumentation and manual shadow memory manipulation. Same as generic KASAN, software tag-based KASAN is strictly a debugging feature.

One of the main reasons to have tag-based KASAN is to be able to perform a similar set of checks as the generic one does, but with lower memory requirements. Comment from Vishwath Mohan : I don't have data on-hand, but anecdotally both ASAN and KASAN have proven problematic to enable for environments that don't tolerate the increased memory pressure well. This includes (a) Low-memory form factors - Wear, TV, Things, lower-tier phones like Go, (c) Connected components like Pixel's visual core [1]. These are both places I'd love to have a low(er) memory footprint option at my disposal. Comment from Evgenii Stepanov : Looking at a live Android device under load, slab (according to /proc/meminfo) + kernel stack take 8-10% available RAM (~350MB). KASAN's overhead of 2x - 3x on top of it is not insignificant. Not having this overhead enables near-production use - ex. running KASAN/KHWASAN kernel on a personal, daily-use device to catch bugs that do not reproduce in test configuration. These are the ones that often cost the most engineering time to track down. CPU overhead is bad, but generally tolerable. RAM is critical, in our experience. Once it gets low enough, OOM-killer makes your life miserable. [1] https://www.blog.google/products/pixel/pixel-visual-core-image-processing-and-machine-learning-pixel-2/ ====== Technical details Software tag-based KASAN mode is implemented in a very similar way to the generic one. This patchset essentially does the following: 1. TCR_TBI1 is set to enable Top Byte Ignore. 2. Shadow memory is used (with a different scale, 1:16, so each shadow byte corresponds to 16 bytes of kernel memory) to store memory tags. 3. All slab objects are aligned to shadow scale, which is 16 bytes. 4. All pointers returned from the slab allocator are tagged with a random tag and the corresponding shadow memory is poisoned with the same value. 5. Compiler instrumentation is used to insert tag checks. Either by calling callbacks or by inlining them (CONFIG_KASAN_OUTLINE and CONFIG_KASAN_INLINE flags are reused). 6. When a tag mismatch is detected in callback instrumentation mode KASAN simply prints a bug report. In case of inline instrumentation, clang inserts a brk instruction, and KASAN has it's own brk handler, which reports the bug. 7. The memory in between slab objects is marked with a reserved tag, and acts as a redzone. 8. When a slab object is freed it's marked with a reserved tag. Bug detection is imprecise for two reasons: 1. We won't catch some small out-of-bounds accesses, that fall into the same shadow cell, as the last byte of a slab object. 2. We only have 1 byte to store tags, which means we have a 1/256 probability of a tag match for an incorrect access (actually even slightly less due to reserved tag values). Despite that there's a particular type of bugs that tag-based KASAN can detect compared to generic KASAN: use-after-free after the object has been allocated by someone else. ====== Testing Some kernel developers voiced a concern that changing the top byte of kernel pointers may lead to subtle bugs that are difficult to discover. To address this concern deliberate testing has been performed. It doesn't seem feasible to do some kind of static checking to find potential issues with pointer tagging, so a dynamic approach was taken. All pointer comparisons/subtractions have been instrumented in an LLVM compiler pass and a kernel module that would print a bug report whenever two pointers with different tags are being compared/subtracted (ignoring comparisons with NULL pointers and with pointers obtained by casting an error code to a pointer type) has been used. Then the kernel has been booted in QEMU and on an Odroid C2 board and syzkaller has been run. This yielded the following results. The two places that look interesting are: is_vmalloc_addr in include/linux/mm.h is_kernel_rodata in mm/util.c Here we compare a pointer with some fixed untagged values to make sure that the pointer lies in a particular part of the kernel address space. Since tag-based KASAN doesn't add tags to pointers that belong to rodata or vmalloc regions, this should work as is. To make sure debug checks to those two functions that check that the result doesn't change whether we operate on pointers with or without untagging has been added. A few other cases that don't look that interesting: Comparing pointers to achieve unique sorting order of pointee objects (e.g. sorting locks addresses before performing a double lock): tty_ldisc_lock_pair_timeout in drivers/tty/tty_ldisc.c pipe_double_lock in fs/pipe.c unix_state_double_lock in net/unix/af_unix.c lock_two_nondirectories in fs/inode.c mutex_lock_double in kernel/events/core.c ep_cmp_ffd in fs/eventpoll.c fsnotify_compare_groups fs/notify/mark.c Nothing needs to be done here, since the tags embedded into pointers don't change, so the sorting order would still be unique. Checks that a pointer belongs to some particular allocation: is_sibling_entry in lib/radix-tree.c object_is_on_stack in include/linux/sched/task_stack.h Nothing needs to be done here either, since two pointers can only belong to the same allocation if they have the same tag. Overall, since the kernel boots and works, there are no critical bugs. As for the rest, the traditional kernel testing way (use until fails) is the only one that looks feasible. Another point here is that tag-based KASAN is available under a separate config option that needs to be deliberately enabled. Even though it might be used in a "near-production" environment to find bugs that are not found during fuzzing or running tests, it is still a debug tool. ====== Benchmarks The following numbers were collected on Odroid C2 board. Both generic and tag-based KASAN were used in inline instrumentation mode. Boot time [1]: * ~1.7 sec for clean kernel * ~5.0 sec for generic KASAN * ~5.0 sec for tag-based KASAN Network performance [2]: * 8.33 Gbits/sec for clean kernel * 3.17 Gbits/sec for generic KASAN * 2.85 Gbits/sec for tag-based KASAN Slab memory usage after boot [3]: * ~40 kb for clean kernel * ~105 kb (~260% overhead) for generic KASAN * ~47 kb (~20% overhead) for tag-based KASAN KASAN memory overhead consists of three main parts: 1. Increased slab memory usage due to redzones. 2. Shadow memory (the whole reserved once during boot). 3. Quaratine (grows gradually until some preset limit; the more the limit, the more the chance to detect a use-after-free). Comparing tag-based vs generic KASAN for each of these points: 1. 20% vs 260% overhead. 2. 1/16th vs 1/8th of physical memory. 3. Tag-based KASAN doesn't require quarantine. [1] Time before the ext4 driver is initialized. [2] Measured as `iperf -s & iperf -c 127.0.0.1 -t 30`. [3] Measured as `cat /proc/meminfo | grep Slab`. ====== Some notes A few notes: 1. The patchset can be found here: https://github.com/xairy/kasan-prototype/tree/khwasan 2. Building requires a recent Clang version (7.0.0 or later). 3. Stack instrumentation is not supported yet and will be added later. This patch (of 25): Tag-based KASAN changes the value of the top byte of pointers returned from the kernel allocation functions (such as kmalloc). This patch updates KASAN hooks signatures and their usage in SLAB and SLUB code to reflect that.

The perf script brstackinsn code that dumps LBR assembler assumes that the last branch in the LBR leads to the sample point. But with skid it's possible that the CPU executes one or more branches before the sample, but which do not appear in the LBR. What happens then is either that the sample point is before the last LBR branch. In this case the dumper sees a negative length and ignores it. Or it the sample point is long after the last branch. Then the dumper sees a very long block and dumps it upto its block limit (16k bytes), which is noise in the output. On typical sample session this can happen regularly. This patch tries to detect and handle the situation. On the last block that is dumped by the LBR dumper we always stop on the first branch. If the block length is negative just scan forward to the first branch. Otherwise scan until a branch is found. The PT decoder already has a function that uses the instruction decoder to detect branches, so we can just reuse it here. Then when a terminating branch is found print an indication and stop dumping. This might miss a few instructions, but at least shows no runaway blocks.

The evlist.get_pollfd function creates file objects from evlist's fds and returns them in a list. The python3 version also sets them to 'close the original descriptor' when the object dies (is closed), by passing True via the 'closefd' arg in the PyFile_FromFd call. The python's closefd doc says: If closefd is False, the underlying file descriptor will be kept open when the file is closed. That's why the following line in python3 closes all evlist fds: evlist.get_pollfd() the returned list is immediately destroyed and that takes down the original events fds. Passing closefd as False to PyFile_FromFd to fix this.

The DFS cache is a hashtable that maps UNC paths to cache entries. A cache entry contains: - the UNC path it is mapped on - how much the the UNC path the entry consumes - flags - a Time-To-Live after which the entry expires - a list of possible targets (linked lists of UNC paths) - a "hint target" pointing the last known working target or the first target if none were tried. This hint lets cifs.ko remember and try working targets first. * Looking for an entry in the cache is done with dfs_cache_find() - if no valid entries are found, a DFS query is made, stored in the cache and returned - the full target list can be copied and returned to avoid race conditions and looped on with the help with the dfs_cache_tgt_iterator * Updating the target hint to the next target is done with dfs_cache_update_tgthint() These functions have a dfs_cache_noreq_XXX() version that doesn't fetches referrals if no entries are found. These versions don't require the tcp/ses/tcon/cifs_sb parameters as a result. Expired entries cannot be used and since they have a pretty short TTL [1] in order for them to be useful for failover the DFS cache adds a delayed work called periodically to keep them fresh. Since we might not have available connections to issue the referral request when refreshing we need to store volume_info structs with credentials and other needed info to be able to connect to the right server. 1: Windows defaults: 5mn for domain-based referrals, 30mn for regular links Signed-off-by: Paulo Alcantara Signed-off-by: Aurelien Aptel Signed-off-by: Steve French commit 21c7acc439b55d0569d7c2fc2eea5194b3910406 Author: Guenter Roeck Date: Thu Dec 27 08:46:38 2018 -0800 h8300: pci: Remove local declaration of pcibios_penalize_isa_irq h8300 builds fail with: In file included from drivers/of/address.c:11: include/linux/pci.h:1966:20: error: redefinition of 'pcibios_penalize_isa_irq' This is because CONFIG_PCI is not enabled, and pcibios_penalize_isa_irq() is now declared as inline static function in generic code if this is the case.

Bruce Fields commit d4b09acf924b84bae77cad090a9d108e70b43643 Author: Vasily Averin Date: Mon Dec 24 14:44:52 2018 +0300 sunrpc: use-after-free in svc_process_common() if node have NFSv41+ mounts inside several net namespaces it can lead to use-after-free in svc_process_common() svc_process_common() /* Setup reply header */ rqstp->rq_xprt->xpt_ops->xpo_prep_reply_hdr(rqstp); <<< HERE svc_process_common() can use incorrect rqstp->rq_xprt, its caller function bc_svc_process() takes it from serv->sv_bc_xprt. The problem is that serv is global structure but sv_bc_xprt is assigned per-netnamespace. According to Trond, the whole "let's set up rqstp->rq_xprt for the back channel" is nothing but a giant hack in order to work around the fact that svc_process_common() uses it to find the xpt_ops, and perform a couple of (meaningless for the back channel) tests of xpt_flags. All we really need in svc_process_common() is to be able to run rqstp->rq_xprt->xpt_ops->xpo_prep_reply_hdr() Bruce J Fields points that this xpo_prep_reply_hdr() call is an awfully roundabout way just to do "svc_putnl(resv, 0);" in the tcp case. This patch does not initialiuze rqstp->rq_xprt in bc_svc_process(), now it calls svc_process_common() with rqstp->rq_xprt = NULL. To adjust reply header svc_process_common() just check rqstp->rq_prot and calls svc_tcp_prep_reply_hdr() for tcp case. To handle rqstp->rq_xprt = NULL case in functions called from svc_process_common() patch intruduces net namespace pointer svc_rqst->rq_bc_net and adjust SVC_NET() definition. Some other function was also adopted to properly handle described case.

metadata uuid - an optional incompat feature to assign a new filesystem UUID without overwriting all metadata blocks, stored only in superblock - more balance messages are printed to system log, initial is in the format of the command line that would be used to start it Fixes: - tag pages of a snapshot to better separate pages that are involved in the snapshot (and need to get synced) from newly dirtied pages that could slow down or even livelock the snapshot operation - improved check of filesystem id associated with a device during scan to detect duplicate devices that could be mixed up during mount - fix device replace state transitions, eg. when it ends up interrupted and reboot tries to restart balance too, or when start/cancel ioctls race - fix a crash due to a race when quotas are enabled during snapshot creation - GFP_NOFS/memalloc_nofs_* fixes due to GFP_KERNEL allocations in transaction context - fix fsync of files with multiple hard links in new directories - fix race of send with transaction commits that create snapshots Core changes: - cleanups: * further removals of now-dead fsync code * core function for finding free extent has been split and provides a base for further cleanups to make the logic more understandable * removed lot of indirect callbacks for data and metadata inodes * simplified refcounting and locking for cloned extent buffers * removed redundant function arguments * defines converted to enums where appropriate - separate reserve for delayed refs from global reserve, update logic to do less trickery and ad-hoc heuristics, move out some related expensive operations from transaction commit or file truncate - dev-replace switched from custom locking scheme to semaphore - remove first phase of balance that tried to make some space for the relocation by calling shrink and grow, this did not work as expected and only introduced more error states due to potential resize failures, slightly improves the runtime as the chunks on all devices are not needlessly enumerated -

That was done using brute force - full tlb flush. This is actually unnecessary, because the mapped-in mappings are all correct and the only mappings which need to be updated after a flush are any unmaps (so that paging works) as well as any pending protection changes. This optimization squeezes out up to 3% from a full kernel rebuild time under memory pressure.

From Stefano Brivio. 3) Implement GRO for plain UDP sockets, from Paolo Abeni. 4) Lots of work from Michał Mirosław to eliminate the VLAN_TAG_PRESENT bit so that we could support the entire vlan_tci value. 5) Rework the IPSEC policy lookups to better optimize more usecases, from Florian Westphal. 6) Infrastructure changes eliminating direct manipulation of SKB lists wherever possible, and to always use the appropriate SKB list helpers. This work is still ongoing... 7) Lots of PHY driver and state machine improvements and simplifications, from Heiner Kallweit. 8) Various TSO deferral refinements, from Eric Dumazet. 9) Add ntuple filter support to aquantia driver, from Dmitry Bogdanov. 10) Batch dropping of XDP packets in tuntap, from Jason Wang. 11) Lots of cleanups and improvements to the r8169 driver from Heiner Kallweit, including support for ->xmit_more.

From Oz Shlomo and others. 22) Add a NETDEV_PRE_CHANGEADDR so that drivers can veto the change and therefore abort the operation before the commit phase (which is the NETDEV_CHANGEADDR event). From Petr Machata. 23) Add indirect call wrappers to avoid retpoline overhead, and use them in the GRO code paths. From Paolo Abeni. 24) Add support for netlink FDB get operations, from Roopa Prabhu. 25) Support bloom filter in mlxsw driver, from Nir Dotan. 26) Add SKB extension infrastructure. This consolidates the handling of the auxiliary SKB data used by IPSEC and bridge netfilter, and is designed to support the needs to MPTCP which could be integrated in the future. 27) Lots of XDP TX optimizations in mlx5 from Tariq Toukan. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-next: (1845 commits) net: dccp: fix kernel crash on module load drivers/net: appletalk/cops: remove redundant if statement and mask bnx2x: Fix NULL pointer dereference in bnx2x_del_all_vlans() on some hw net/net_namespace: Check the return value of register_pernet_subsys() net/netlink_compat: Fix a missing check of nla_parse_nested ieee802154: lowpan_header_create check must check daddr net/mlx4_core: drop useless LIST_HEAD mlxsw: spectrum: drop useless LIST_HEAD net/mlx5e: drop useless LIST_HEAD iptunnel: Set tun_flags in the iptunnel_metadata_reply from src net/mlx5e: fix semicolon.cocci warnings staging: octeon: fix build failure with XFRM enabled net: Revert recent Spectre-v1 patches. can: af_can: Fix Spectre v1 vulnerability packet: validate address length if non-zero nfc: af_nfc: Fix Spectre v1 vulnerability phonet: af_phonet: Fix Spectre v1 vulnerability net: core: Fix Spectre v1 vulnerability net: minor cleanup in skb_ext_add() net: drop the unused helper skb_ext_get() ... commit 7f9f852c75e7d776b078813586c76a2bc7dca993 Merge: 3f03bf93947fa 93d77e7f1410c Author: Linus Torvalds Date: Thu Dec 27 12:08:33 2018 -0800 Merge tag 'modules-for-v4.21' of git://git.kernel.org/pub/scm/linux/kernel/git/jeyu/linux Pull modules updates from Jessica Yu: - Some modules-related kallsyms cleanups and a kallsyms fix for ARM. - Include keys from the secondary keyring in module signature verification. * tag 'modules-for-v4.21' of git://git.kernel.org/pub/scm/linux/kernel/git/jeyu/linux: ARM: module: Fix function kallsyms on Thumb-2 module: Overwrite st_size instead of st_info module: make it clearer when we're handling kallsyms symbols vs exported symbols modsign: use all trusted keys to verify module signature commit 3f03bf93947fa2a2b84fac56e93c65d4fffed7f1 Merge: fb2a624d5fe8b b49d564344f77 Author: Linus Torvalds Date: Thu Dec 27 12:04:52 2018 -0800 Merge branch 'next-general' of git://git.kernel.org/pub/scm/linux/kernel/git/jmorris/linux-security Pull general security subsystem updates from James Morris: "The main changes here are Paul Gortmaker's removal of unneccesary module.h infrastructure" * 'next-general' of git://git.kernel.org/pub/scm/linux/kernel/git/jmorris/linux-security: security: integrity: partial revert of make ima_main explicitly non-modular security: fs: make inode explicitly non-modular security: audit and remove any unnecessary uses of module.h security: integrity: make evm_main explicitly non-modular keys: remove needless modular infrastructure from ecryptfs_format security: integrity: make ima_main explicitly non-modular tomoyo: fix small typo commit fb2a624d5fe8b9206d14bff52da7a368a3a8374c Merge: 047ce6d380e8e ee1a84fdfeedf Author: Linus Torvalds Date: Thu Dec 27 12:01:58 2018 -0800 Merge tag 'selinux-pr-20181224' of git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/selinux Pull selinux patches from Paul Moore: "I already used my best holiday pull request lines in the audit pull request, so this one is going to be a bit more boring, sorry about that.

This fixes a bug where the superblock validation fails on big endian devices with the following error: F2FS-fs (sda1): Wrong segment_count / block_count (61439 > 0) F2FS-fs (sda1): Can't find valid F2FS filesystem in 1th superblock F2FS-fs (sda1): Wrong segment_count / block_count (61439 > 0) F2FS-fs (sda1): Can't find valid F2FS filesystem in 2th superblock As result of this the partition cannot be mounted. With this patch applied the superblock validation works fine and the partition can be mounted again: F2FS-fs (sda1): Mounted with checkpoint version = 7c84 My little endian x86-64 hardware was able to mount the partition without this fix. To confirm that mounting f2fs filesystems works on big endian machines again I tested this on a 32-bit MIPS big endian (lantiq) device.

Mostly useful to shrink the kernel & as preparation for nanoMIPS support which does not yet include FP. - MIPS SIMD Architecture (MSA) vector register context is now exposed by ptrace via a new NT_MIPS_MSA regset. - ASIDs are now stored as 64b values even for MIPS32 kernels, expanding the ASID version field sufficiently that we don't need to worry about overflow & avoiding rare issues with reused ASIDs that have been observed in the wild. - The branch delay slot "emulation" page is now mapped without write permission for the user, preventing its use as a nice location for attacks to execute malicious code from. - Support for ioremap_prot(), primarily to allow gdb or other ptrace users the ability to view their tracee's memory using the same cache coherency attribute. - Optimizations to more cpu_has_* macros, allowing more to be compile-time constant where possible. - Enable building the whole kernel with UBSAN instrumentation. - Enable building the kernel with link-time dead code & data elimination.

Instead, arrange for tcp_push() to be called (at least) once per data payload. This results in more MSS-sized packets and fewer packets overall (5-10% reduction in my tests with typical OSD request sizes). See commits 2f5338442425 ("tcp: allow splice() to build full TSO packets"), 35f9c09fe9c7 ("tcp: tcp_sendpages() should call tcp_push() once") and ae62ca7b0321 ("tcp: fix MSG_SENDPAGE_NOTLAST logic") for details. Here is an example of a packet size histogram for 128K OSD requests (MSS = 1448, top 5): Before: SIZE COUNT 1448 777700 952 127915 1200 39238 1219 9806 21 5675 After: SIZE COUNT 1448 897280 21 6201 1019 2797 643 2739 376 2479 We could do slightly better by explicitly corking the socket but it's not clear it's worth it.

This is harmful for messages with multiple data items. On top of that, we don't need to signal the end of a data payload either because it is always followed by a footer. We used to signal "more" unconditionally, until commit fe38a2b67bc6 ("libceph: start defining message data cursor"). Part of a large series, it introduced cursor->last_piece and also mistakenly inverted the hint by passing last_piece for "more". This was corrected with commit c2cfa1940097 ("libceph: Fix ceph_tcp_sendpage()'s more boolean usage"). As it is, last_piece is not helping at all: because Nagle algorithm is disabled, for a simple message with two 512-byte data items we end up emitting three packets: front + first data item, second data item and footer. Go back to the original pre-fe38a2b67bc6 behavior -- a single packet in most cases.

We gained support for two or three i.MX SoCs in here and that mostly means a lot of driver code and data. Beyond that platform, there are some new Mediatek, Amlogic, and Qualcomm clk drivers added in here, and then we get to the long tail of driver updates and non-critical fixes all around, including code for vendors such as Renesas, Rockchip, Nvidia, and Allwinner. Overall, the driver updates look normal. Apart from the usual driver updates we have an update to make registering OF based clk providers a little simpler when they're devices created as a child of a device backed by a node in DT. Drivers don't have to jump through hoops to unregister the provider upon driver removal anymore because the API does the right thing and uses the parent device DT node.

If it's *really* too small, nothing will work, and this got caught by syzbot recently (on a new kmem_cache_create_usercopy() call) Just set a minimum msize to 4k in both code paths, until someone complains they have a use-case for a smaller msize. We need to check in both mount option and server reply individually because the msize for the first version request would be unchecked with just a global check on clnt->msize.

This is not necessary and it triggers a circular lockdep warning. This is because fiemap_fill_next_extent() could trigger a page fault when it writes into page which triggers a page fault. If that page is mmaped from the inline file in question, this could very well result in a deadlock. This problem can be reproduced using generic/519 with a file system configuration which has the inline_data feature enabled.

However, inet_hashinfo2_init() is marked as __init(), and thus the kernel panics when dccp is loaded as module. Removing __init() tag from inet_hashinfo2_init() is not feasible because it calls into __init functions in mm. This patch adds inet_hashinfo2_init_mod() function that can be called after the init phase is done; changes dccp_init() to call the new function; un-marks inet_hashinfo2_init() as exported.

Masking a u8 return value from inb() with 0xFF is also redundant and can also be emoved. Similarly, the two different outb calls are identical as the mask of 0xff on the second outb is redundant since a u8 is being written, so the if statement is also redundant and can be also removed. Detected by CoverityScan, CID#1475639 ("Identical code for different branches") V2: Remove the if statement for the outb calls, thanks to David Miller for spotting this.

When a file locked by one node and we trying to lock it from another node it fail with errno 5 (EIO) but in that case errno must be set to (EACCES | EAGAIN). This isn't happening when we try to lock file second time on same node. In this case it returns EACCES as expected. Also this issue not reproduces when we use SMB1 protocol (vers=1.0 in mount options). Further investigation showed that the mapping from status_to_posix_error is different for SMB1 and SMB2+ implementations. For SMB1 mapping is [NT_STATUS_LOCK_NOT_GRANTED to ERRlock] (See fs/cifs/netmisc.c line 66) but for SMB2+ mapping is [STATUS_LOCK_NOT_GRANTED to -EIO] (see fs/cifs/smb2maperror.c line 383) Quick changes in SMB2+ mapping from EIO to EACCES has fixed issue.

The main issue here is that mainline U-Boot configures EBase to a value near the end of system memory. And with CONFIG_CPU_MIPSR2_IRQ_VI disabled, trap_init() will not allocate a new area to place the exception handler. The original value will be used and the handler will be copied to this location, which might already be used by some userspace application. The MT7688 supports VI - its config3 register is 0x00002420, so VInt (Bit 5) is set. But without setting CONFIG_CPU_MIPSR2_IRQ_VI this bit will not be evaluated to result in "cpu_has_vi" being set. This patch now selects CONFIG_CPU_MIPSR2_IRQ_VI on MT7620/8 which results trap_init() to allocate some memory for the exception handler. Please note that this issue was not seen with the Mediatek U-Boot version, as it does not touch EBase (stays at default of 0x8000.0000). This is strictly also not correct as the kernel (_text) resides here.

Instead of adding an additional loop in the hotpath as in e31ac32d3b, this diff instead generates separate versions of the code using macros, and the entry routines choose which version once. This results in a 5% performance improvement vs. adding a loop to the hot path. This is the same strategy chosen by the intel isa-l_crypto library. The key size checks are removed from the c code where appropriate. Note that this diff depends on using gcm_context_data - 256 bit keys require 16 HashKeys + 15 expanded keys, which is larger than struct crypto_aes_ctx, so they are stored in struct gcm_context_data.

Pass the macros as arguments, and merge them. This facilitates additional refactoring, by requiring changes in only one place. The GCM_ENC_DEC macro was moved above the CONFIG_AS_AVX* ifdefs, since it will be used by both AVX and AVX2.

It started with: strncmp(str, const, sizeof(const) - 1) But then Joe Perches mentioned that if a const is not used, the sizeof() will be the size of a pointer, which can be bad. And that gcc will optimize strlen("const") into "sizeof("const") - 1". Thinking about this more, a quick grep in the kernel tree found several (thousands!) of cases that use this construct. A quick grep also revealed that there's probably several bugs in that use case. Some are that people forgot the "- 1" (which I found) and others could be that the constant for the sizeof is different than the constant (although, I haven't found any of those, but I also didn't look hard). I figured the best thing to do is to create a helper macro and place it into include/linux/string.h. And go around and fix all the open coded versions of it later. Note, gcc appears to optimize this when we make it into an always_inline static function, which removes a lot of issues that a macro produces.

This feature can be enabled by passing "efi=old_map" as kernel command line argument. But, efi_unmap_pages() unmaps EFI boot services code/data regions *only* from efi_pgd and hence cannot be used for unmapping EFI boot services code/data regions from swapper_pg_dir. Introduce a temporary fix to not unmap EFI boot services code/data regions when EFI_OLD_MEMMAP is enabled while working on a real fix. - EFI_MIXED_MODE is another feature where a 64-bit kernel runs on a 64-bit platform crippled by a 32-bit firmware. To support EFI_MIXED_MODE, all RAM (i.e. namely EFI regions like EFI_CONVENTIONAL_MEMORY, EFI_LOADER_, EFI_BOOT_SERVICES_ and EFI_RUNTIME_CODE/DATA regions) is mapped into efi_pgd all the time to facilitate EFI runtime calls access it's arguments in 1:1 mode. Hence, don't unmap EFI boot services code/data regions when booted in mixed mode.

This is particularly dangerous if the buffer is on the stack. For example: char buf[8]; char secret = "secret"; struct seq_buf s; seq_buf_init(&s, buf, sizeof(buf)); seq_buf_puts(&s, "foo"); printk("Message is %s\n", buf); Can result in: Message is fooªªªªªsecret We could require all users to memset() their buffer to zero before use. But that seems likely to be forgotten and lead to bugs. Instead we can change seq_buf_puts() to always leave the buffer in a null-terminated state. The only downside is that this makes the buffer 1 character smaller for seq_buf_puts(), but that seems like a good trade off.

This watchdog is subcomponent of the PON (Power On) peripheral, in the same way as pwrkey/resin buttons. It works with two timers (2-stages), the first one generates an IRQ to the main SoC (APQ8016/MSM8916), the second one performs the reset. This driver expects the following device hierarchy: [pm8916]->[pm8916-pon]->[pm8916-wdt] It uses the pm8916 regmap to access PM8916 registers.

The hardware can be configured to trigger interrupts when a mailbox is empty or full. Add support for these shared mailboxes to the HSP driver. The initial use for the mailboxes is the Tegra Combined UART. For this purpose, we use interrupts to receive data, and spinning to wait for the transmit mailbox to be emptied to minimize unnecessary overhead. Based on work by Mikko Perttunen .

They are bidirectional links with both a producer and a consumer. Interrupts are used to let the consumer know when data was written to the mailbox by the producer, and to let the producer know when the consumer has read the data from the mailbox. These interrupts are mapped to one or more "shared interrupts". Typically each processor in the system owns one of these shared interrupts. Add documentation to the device tree bindings about how clients can use mailbox specifiers to request a specific shared mailbox and select which direction they drive. Also document how to specify the shared interrupts in addition to the existing doorbell interrupt.

This will allow triggering of overwrite on Intel NVDIMMs. The overwrite operation can take tens of minutes. When the overwrite DSM is issued successfully, the NVDIMMs will be unaccessible. The kernel will do backoff polling to detect when the overwrite process is completed. According to the DSM spec v1.7, the 128G NVDIMMs can take up to 15mins to perform overwrite and larger DIMMs will take longer. Given that overwrite puts the DIMM in an indeterminate state until it completes introduce the NDD_SECURITY_OVERWRITE flag to prevent other operations from executing when overwrite is happening. The NDD_WORK_PENDING flag is added to denote that there is a device reference on the nvdimm device for an async workqueue thread context.

To make it easy by keeping a script and which will generate the uapi header and syscall table file. This change will also help to unify the implemen- tation across all architectures. The system call table generation script is added in kernel/syscalls directory which contain the scripts to generate both uapi header file and system call table files. The syscall.tbl will be input for the scripts. syscall.tbl contains the list of available system calls along with system call number and corresponding entry point. Add a new system call in this architecture will be possible by adding new entry in the syscall.tbl file. Adding a new table entry consisting of: - System call number. - ABI. - System call name. - Entry point name. syscallhdr.sh and syscalltbl.sh will generate uapi header unistd_32.h and syscall_table.h files respectively. Both .sh files will parse the content syscall.tbl to generate the header and table files. unistd_32.h will be included by uapi/asm/unistd.h and syscall_table.h is included by kernel/syscall.S - the real system call table. ARM, s390 and x86 architecuture does have similar support. I leverage their implementation to come up with a generic solution.

We have to change the value of NR- _SYSCALLS, if we add or delete a system call. One of the patch in this patch series has a script which will generate a uapi header based on syscall.tbl file. The syscall.tbl file contains the total number of system calls information. So we have two option to update NR_SY- CALLS value. 1. Update NR_SYSCALLS in asm/unistd.h manually by count- ing the no.of system calls. No need to update NR_SYS- CALLS until we either add a new system call or delete existing system call. 2. We can keep this feature it above mentioned script, that will count the number of syscalls and keep it in a generated file. In this case we don't need to expli- citly update NR_SYSCALLS in asm/unistd.h file. The 2nd option will be the recommended one. For that, I added the __NR_syscalls macro in uapi/asm/unistd.h along with NR_SYSCALLS asm/unistd.h. The macro __NR_syscalls also added for making the name convention same across all architecture. While __NR_syscalls isn't strictly part of the uapi, having it as part of the generated header to simplifies the implementation. We also need to enclose this macro with #ifdef __KERNEL__ to avoid side effects.

Changes: * instead of struct security_mnt_opt use an opaque pointer initialized to NULL. * security_sb_eat_lsm_opts(), security_sb_parse_opts_str() and security_free_mnt_opts() take it as var argument (i.e. as void **); call sites are unchanged. * security_sb_set_mnt_opts() and security_sb_remount() take it by value (i.e. as void *). * new method: ->sb_free_mnt_opts(). Takes void *, does whatever freeing that needs to be done. * ->sb_set_mnt_opts() and ->sb_remount() might get NULL as mnt_opts argument, meaning "empty".

Getting rid of that allows for simpler calling conventions for setup_security_options() (caller is responsible for freeing mnt_opts in all cases). 2) on remount we want to use ->sb_remount(), not ->sb_set_mnt_opts(), same as we would if not for FS_BINARY_MOUNTDATA. Behaviours *are* close (in fact, selinux sb_set_mnt_opts() ought to punt to sb_remount() in "already initialized" case), but let's handle that uniformly. And the only reason why the original btrfs changes didn't go for security_sb_remount() in btrfs_remount() case is that it hadn't been exported. Let's export it for a while - it'll be going away soon anyway.

However, the iomap implementation continues to check all blocks up to from+count, which is beyond the page, and can even be well beyond the iop->uptodate bitmap. I think the worst that will happen is that we may eventually find a zero bit and return "not partially uptodate" when it would have otherwise returned true, and skip the optimization. Still, it's clearly an invalid memory access that must be fixed. So: fix this by limiting the search to within the page as is done in the non-iomap variant, block_is_partially_uptodate().

In the first five patches, Tariq did minor improvements to mlx5 tx path, for better debug-ability and code structuring. Next two patches lay down the foundation for MPWQE implementation to store the in-flight XDP TX information for multiple packets of one descriptor (WQE). Next: Support Enhanced Multi-Packet TX WQE for XDP In this patch we add support for the HW feature, which is supported starting from ConnectX-5.

CPU: Intel(R) Xeon(R) CPU E5-2680 v3 @ 2.50GHz XDP_TX: We see a huge gain on single port ConnectX-5, and reach the 100 Mpps milestone. * Single-port HCA: Before: 70 Mpps After: 100 Mpps (+42.8%) * Dual-port HCA: Before: 51.7 Mpps After: 57.3 Mpps (+10.8%) * In both cases we tested traffic on one port and for now On Dual-port HCAs we see only a small gain, we are working to overcome this bottleneck, but for the moment only with experimental firmware on dual port HCAs we can reach the wanted numbers as seen on Single-port HCAs. XDP_REDIRECT: Redirect from (A) ConnectX-5 to (B) ConnectX-5. Due to a setup limitation, (A) and (B) are on different NUMA nodes, so absolute performance numbers are not optimal. - Note: Below is the transmit rate of (B), not the redirect rate of (A) which is in some cases higher. * (B) is single-port: Before: 77 Mpps After: 90 Mpps (+16.8%) * (B) is dual-port: Before: 61 Mpps After: 72 Mpps (+18%) Last patch adds a knob in mlx5 ethtool private flag to turn on/off XDP TX MPWQE. ==================== Signed-off-by: David S.

It probably doesn't make sense to keep the support code around just for that, so start deprecating the support.

While it's required on some systems (e.g. opensuse), it's completely unnecessary on the others, where only -lbdf is sufficient (debian). This patch streamlines (and renames) the following feature checks: feature-libbfd - only link against -lbfd (debian), see commit 2cf9040714f3 ("perf tools: Fix bfd dependency libraries detection") feature-libbfd-liberty - link against -lbfd and -liberty feature-libbfd-liberty-z - link against -lbfd, -liberty and -lz (opensuse), see commit 280e7c48c3b8 ("perf tools: fix BFD detection on opensuse") (feature-liberty{,-z} were renamed to feature-libbfd-liberty{,z} for clarity) The main motivation is to fix this feature test for bpftool which is currently broken on debian (libbfd feature shows OFF, but we still unconditionally link against -lbfd and it works). Tested on debian with only -lbfd installed (without -liberty); I'd appreciate if somebody on the other systems can test this new detection method.

For obvious reasons, loading the guest's GPR snapshot prior to VM-Enter and saving the snapshot after VM-Exit is done via handcoded assembly. The assembly blob is written as inline asm so that it can easily access KVM-defined structs that are used to hold guest state, e.g. moving the blob to a standalone assembly file would require generating defines for struct offsets. The other relevant aspect of VMX transitions in KVM is the handling of VM-Exits. KVM doesn't employ a separate VM-Exit handler per se, but rather treats the VMX transition as a mega instruction (with many side effects), i.e. sets the VMCS.HOST_RIP to a label immediately following VMLAUNCH/VMRESUME. The label is then exposed to C code via a global variable definition in the inline assembly. Because of the global variable, KVM takes steps to (attempt to) ensure only a single instance of the owning C function, e.g. vmx_vcpu_run, is generated by the compiler. The earliest approach placed the inline assembly in a separate noinline function[1]. Later, the assembly was folded back into vmx_vcpu_run() and tagged with __noclone[2][3], which is still used today. After moving to __noclone, an edge case was encountered where GCC's -ftracer optimization resulted in the inline assembly blob being duplicated. This was "fixed" by explicitly disabling -ftracer in the __noclone definition[4]. Recently, it was found that disabling -ftracer causes build warnings for unsuspecting users of __noclone[5], and more importantly for KVM, prevents the compiler for properly optimizing vmx_vcpu_run()[6]. And perhaps most importantly of all, it was pointed out that there is no way to prevent duplication of a function with 100% reliability[7], i.e. more edge cases may be encountered in the future. So to summarize, the only way to prevent the compiler from duplicating the global variable definition is to move the variable out of inline assembly, which has been suggested several times over[1][7][8]. Resolve the aforementioned issues by moving the VMLAUNCH+VRESUME and VM-Exit "handler" to standalone assembly sub-routines. Moving only the core VMX transition codes allows the struct indexing to remain as inline assembly and also allows the sub-routines to be used by nested_vmx_check_vmentry_hw(). Reusing the sub-routines has a happy side-effect of eliminating two VMWRITEs in the nested_early_check path as there is no longer a need to dynamically change VMCS.HOST_RIP. Note that callers to vmx_vmenter() must account for the CALL modifying RSP, e.g. must subtract op-size from RSP when synchronizing RSP with VMCS.HOST_RSP and "restore" RSP prior to the CALL. There are no great alternatives to fudging RSP. Saving RSP in vmx_enter() is difficult because doing so requires a second register (VMWRITE does not provide an immediate encoding for the VMCS field and KVM supports Hyper-V's memory-based eVMCS ABI). The other more drastic alternative would be to use eschew VMCS.HOST_RSP and manually save/load RSP using a per-cpu variable (which can be encoded as e.g. gs:[imm]). But because a valid stack is needed at the time of VM-Exit (NMIs aren't blocked and a user could theoretically insert INT3/INT1ICEBRK at the VM-Exit handler), a dedicated per-cpu VM-Exit stack would be required. A dedicated stack isn't difficult to implement, but it would require at least one page per CPU and knowledge of the stack in the dumpstack routines. And in most cases there is essentially zero overhead in dynamically updating VMCS.HOST_RSP, e.g. the VMWRITE can be avoided for all but the first VMLAUNCH unless nested_early_check=1, which is not a fast path. In other words, avoiding the VMCS.HOST_RSP by using a dedicated stack would only make the code marginally less ugly while requiring at least one page per CPU and forcing the kernel to be aware (and approve) of the VM-Exit stack shenanigans.

If there isn't a reboot in progress, ____kvm_handle_fault_on_reboot() treats any exception as fatal to KVM and invokes kvm_spurious_fault(), which in turn generates a BUG() to get a stack trace and die. When it was originally added by commit 4ecac3fd6dc2 ("KVM: Handle virtualization instruction #UD faults during reboot"), the "call" to kvm_spurious_fault() was handcoded as PUSH+JMP, where the PUSH'd value is the RIP of the faulting instructing. The PUSH+JMP trickery is necessary because the exception fixup handler code lies outside of its associated function, e.g. right after the function. An actual CALL from the .fixup code would show a slightly bogus stack trace, e.g. an extra "random" function would be inserted into the trace, as the return RIP on the stack would point to no known function (and the unwinder will likely try to guess who owns the RIP). Unfortunately, the JMP was replaced with a CALL when the macro was reworked to not spin indefinitely during reboot (commit b7c4145ba2eb "KVM: Don't spin on virt instruction faults during reboot"). This causes the aforementioned behavior where a bogus function is inserted into the stack trace, e.g. my builds like to blame free_kvm_area(). Revert the CALL back to a JMP. The changelog for commit b7c4145ba2eb ("KVM: Don't spin on virt instruction faults during reboot") contains nothing that indicates the switch to CALL was deliberate. This is backed up by the fact that the PUSH was left intact. Note that an alternative to the PUSH+JMP magic would be to JMP back to the "real" code and CALL from there, but that would require adding a JMP in the non-faulting path to avoid calling kvm_spurious_fault() and would add no value, i.e. the stack trace would be the same.

System-Wide mode (default): When the host configures Intel PT to collect trace packets of the entire system, it can leave the relevant VMX controls clear to allow VMX-specific packets to provide information across VMX transitions. KVM guest will not aware this feature in this mode and both host and KVM guest trace will output to host buffer. b. Host-Guest mode: Host can configure trace-packet generation while in VMX non-root operation for guests and root operation for native executing normally. Intel PT will be exposed to KVM guest in this mode, and the trace output to respective buffer of host and guest. In this mode, tht status of PT will be saved and disabled before VM-entry and restored after VM-exit if trace a virtual machine.

In addition to that the GPUs have 6 NVLinks which are connected to other GPUs and the POWER9 CPU. POWER9 chips have a special unit on a die called an NPU which is an NVLink2 host bus adapter with p2p connections to 2 to 3 GPUs, 3 or 2 NVLinks to each. These systems also support ATS (address translation services) which is a part of the NVLink2 protocol. Such GPUs also share on-board RAM (16GB or 32GB) to the system via the same NVLink2 so a CPU has cache-coherent access to a GPU RAM. This exports GPU RAM to the userspace as a new VFIO device region. This preregisters the new memory as device memory as it might be used for DMA. This inserts pfns from the fault handler as the GPU memory is not onlined until the vendor driver is loaded and trained the NVLinks so doing this earlier causes low level errors which we fence in the firmware so it does not hurt the host system but still better be avoided; for the same reason this does not map GPU RAM into the host kernel (usual thing for emulated access otherwise). This exports an ATSD (Address Translation Shootdown) register of NPU which allows TLB invalidations inside GPU for an operating system. The register conveniently occupies a single 64k page. It is also presented to the userspace as a new VFIO device region. One NPU has 8 ATSD registers, each of them can be used for TLB invalidation in a GPU linked to this NPU. This allocates one ATSD register per an NVLink bridge allowing passing up to 6 registers. Due to the host firmware bug (just recently fixed), only 1 ATSD register per NPU was actually advertised to the host system so this passes that alone register via the first NVLink bridge device in the group which is still enough as QEMU collects them all back and presents to the guest via vPHB to mimic the emulated NPU PHB on the host. In order to provide the userspace with the information about GPU-to-NVLink connections, this exports an additional capability called "tgt" (which is an abbreviated host system bus address). The "tgt" property tells the GPU its own system address and allows the guest driver to conglomerate the routing information so each GPU knows how to get directly to the other GPUs. For ATS to work, the nest MMU (an NVIDIA block in a P9 CPU) needs to know LPID (a logical partition ID or a KVM guest hardware ID in other words) and PID (a memory context ID of a userspace process, not to be confused with a linux pid). This assigns a GPU to LPID in the NPU and this is why this adds a listener for KVM on an IOMMU group. A PID comes via NVLink from a GPU and NPU uses a PID wildcard to pass it through. This requires coherent memory and ATSD to be available on the host as the GPU vendor only supports configurations with both features enabled and other configurations are known not to work. Because of this and because of the ways the features are advertised to the host system (which is a device tree with very platform specific properties), this requires enabled POWERNV platform. The V100 GPUs do not advertise any of these capabilities via the config space and there are more than just one device ID so this relies on the platform to tell whether these GPUs have special abilities such as NVLinks.

There is an exception though: an NVLink bridge which is attached to the corresponding GPU's IOMMU group making it a master. Now we have POWER9 systems with GPUs connected to each other directly bypassing PCI. At the moment we do not control state of these links so we have to put such interconnected GPUs to one IOMMU group which means that the old scheme with one GPU as a master won't work - there will be up to 3 GPUs in such group. This introduces a npu_comp struct which represents a compound IOMMU group made of multiple PEs - PCI PEs (for GPUs) and NPU PEs (for NVLink bridges). This converts the existing NVLink1 code to use the new scheme. >From now on, each PE must have a valid iommu_table_group_ops which will either be called directly (for a single PE group) or indirectly from a compound group handlers. This moves IOMMU group registration for NVLink-connected GPUs to npu-dma.c. For POWER8, this stores a new compound group pointer in the PE (so a GPU is still a master); for POWER9 the new group pointer is stored in an NPU (which is allocated per a PCI host controller).

Soon we will have compound IOMMU groups with several PEs from several different PHB (such as interconnected GPUs and NPUs) so there will be no single master but a one big IOMMU group. This makes a first step and converts an NPU PE with a set of extern function to a table group. This should cause no behavioral change.

Commit d41ce7b1bcc3e ("powerpc/powernv/npu: Do not try invalidating 32bit table when 64bit table is enabled") did just that but in pci-ioda.c while it actually belongs to npu-dma.c. This moves the single TVE handling to npu-dma.c. This does not implement restoring though as it is highly unlikely that we can set the table to PCI PE and cannot to NPU PE and if that fails, we could only set 32bit table to NPU PE and this configuration is not really supported or wanted.

This moved IOMMU groups setup to a separate helper which registers a group and adds devices as before. This does not make a difference as IOMMU groups are not used anyway; the only dependency here is that iommu_add_device() requires a valid pointer to an iommu_table (set by set_iommu_table_base()). To keep the old behaviour, this does not add new IOMMU groups for PEs with no DMA weight and also skips NVLink bridges which do not have pci_controller_ops::setup_bridge (the normal way of adding PEs).

The pseries platform registers IOMMU groups from the pci_controller_ops::dma_bus_setup() hook and adds devices from the pci_controller_ops::dma_dev_setup() hook. The very same bus notifier used for powernv does not add devices for pseries though as __of_scan_bus() adds devices first, then it does the bus/dev DMA setup. Both platforms use iommu_add_device() which takes a device and expects it to have a valid IOMMU table struct with an iommu_table_group pointer which in turn points the iommu_group struct (which represents an IOMMU group). Although the helper seems easy to use, it relies on some pre-existing device configuration and associated data structures which it does not really need. This simplifies iommu_add_device() to take the table_group pointer directly. Pseries already has a table_group pointer handy and the bus notified is not used anyway. For powernv, this copies the existing bus notifier, makes it work for powernv only which means an easy way of getting to the table_group pointer. This was tested on VFs but should also support physical PCI hotplug. Since iommu_add_device() receives the table_group pointer directly, pseries does not do TCE cache invalidation (the hypervisor does) nor allow multiple groups per a VFIO container (in other words sharing an IOMMU table between partitionable endpoints), this removes iommu_table_group_link from pseries.

However newer chip revision added a PID wildcard support so there is no more need to call OPAL every time a new context is initialized. Also, since the PID wildcard support was added, skiboot does not clear wildcard entries in the NPU so these remain in the hardware till the system reboot. This moves LPID and wildcard programming to the PE setup code which executes once during the booting process so NPU2 context init/destroy won't need to do additional configuration. This replaces the check for FW_FEATURE_OPAL with a check for npu!=NULL as this is the way to tell if the NPU support is present and configured. This moves pnv_npu2_init() declaration as pseries should be able to use it. This keeps pnv_npu2_map_lpar() in powernv as pseries is not allowed to call that. This exports pnv_npu2_map_lpar_dev() as following patches will use it from the VFIO driver. While at it, replace redundant list_for_each_entry_safe() with a simpler list_for_each_entry().

We have to change the value of NR_syscalls, if we add or delete a system call. One of the patch in this patch series has a script which will generate a uapi header based on syscall.tbl file. The syscall.tbl file contains the number of system call information. So we have two option to update NR_syscalls value. 1. Update NR_syscalls in asm/unistd.h manually by count- ing the no.of system calls. No need to update NR_sys- calls until we either add a new system call or delete existing system call. 2. We can keep this feature in above mentioned script, that will count the number of syscalls and keep it in a generated file. In this case we don't need to expli- citly update NR_syscalls in asm/unistd.h file. The 2nd option will be the recommended one. For that, I added the __NR_syscalls macro in uapi/asm/unistd.h along with NR_syscalls asm/unistd.h. The macro __NR_syscalls also added for making the name convention same across all architecture. While __NR_syscalls isn't strictly part of the uapi, having it as part of the generated header to simplifies the implementation. We also need to enclose this macro with #ifdef __KERNEL__ to avoid side effects.

It is not possible to move tm_recheckpoint to happen earlier, because it is required to get the checkpointed registers from userspace, with __get_user(), thus, the only way to avoid this undesired behavior is delaying the MSR[TS] set. The 32-bits signal handler seems to be safe this current issue, but, it might be exposed to the preemption issue, thus, disabling preemption in this chunk of code. Changes from v2: * Run the critical section with preempt_disable.

The name field in struct device is a const char *, where as ib_device->name is a char array of size IB_DEVICE_NAME_MAX, and it is pre-initialized to zeros. Since iw_cm_map() was using memcpy() to copy in the device name, and copying IWPM_DEVNAME_SIZE bytes, it ends up copying past the end of the source device name string and copying random bytes. This results in iwpmd failing the REGISTER_PID request from iwcm. Thus port mapping is broken. Validate the device and if names, and use strncpy() to inialize the entire message field.

The accessed bit is used to age a page and the dirty bit to track whether a page is dirty or not. Now that we support nested guests there are three ptes which track the state of the same page: - The partition-scoped page table in the L1 guest, mapping L2->L1 address - The partition-scoped page table in the host for the L1 guest, mapping L1->L0 address - The shadow partition-scoped page table for the nested guest in the host, mapping L2->L0 address The idea is to attempt to keep the rc state of these three ptes in sync, both when setting and when clearing rc bits. When setting the bits we achieve consistency by: - Initially setting the bits in the shadow page table as the 'and' of the other two. - When updating in software the rc bits in the shadow page table we ensure the state is consistent with the other two locations first, and update these before reflecting the change into the shadow page table. i.e. only set the bits in the L2->L0 pte if also set in both the L2->L1 and the L1->L0 pte. When clearing the bits we achieve consistency by: - The rc bits in the shadow page table are only cleared when discarding a pte, and we don't need to record this as if either bit is set then it must also be set in the pte mapping L1->L0. - When L1 clears an rc bit in the L2->L1 mapping it __should__ issue a tlbie instruction - This means we will discard the pte from the shadow page table meaning the mapping will have to be setup again. - When setup the pte again in the shadow page table we will ensure consistency with the L2->L1 pte. - When the host clears an rc bit in the L1->L0 mapping we need to also clear the bit in any ptes in the shadow page table which map the same gfn so we will be notified if a nested guest accesses the page. This case is what this patch specifically concerns. - We can search the nest_rmap list for that given gfn and clear the same bit from all corresponding ptes in shadow page tables. - If a nested guest causes either of the rc bits to be set by software in future then we will update the L1->L0 pte and maintain consistency. With the process outlined above we aim to maintain consistency of the 3 pte locations where we track rc for a given guest page.

Currently when creating these ptes we take the rc bits from the pte for the L1 guest address to host address translation. This is incorrect as we must also factor in the rc bits from the pte for the nested guest address to L1 guest address translation (as contained in the L1 guest partition table for the nested guest). By not calculating these bits correctly L1 may not have been correctly notified when it needed to update its rc bits in the partition table it maintains for its nested guest. Modify the code so that the rc bits in the resultant pte for the L2->L0 translation are the 'and' of the rc bits in the L2->L1 pte and the L1->L0 pte, also accounting for whether this was a write access when setting the dirty bit.

This rmap list is located by indexing the rmap array in the memslot by L1 gfn. When we come to search for these entries we only know the L1 page size (which could be PAGE_SIZE, 2M or a 1G page) and so can only select a gfn aligned to that size. This means that when we insert the entry, so we can find it later, we need to align the gfn we use to select the rmap list in which to insert the entry to L1 page size as well. By not doing this we were missing nested rmap entries when modifying L1 ptes which were for a page also passed through to an L2 guest.

This is conditional on VIRTIO_NET_F_CTRL_GUEST_OFFLOADS. Virtio-net negotiates TSO4 and TSO6 separately, but ethtool does not distinguish between the two. Display LRO as on only if any offload is active. RTNL is held while calling virtnet_set_features, same as on the path from virtnet_xdp_set. Changes v1 -> v2 - allow ethtool config (-K) only if VIRTIO_NET_F_CTRL_GUEST_OFFLOADS - show LRO as enabled if any LRO variant is enabled - do not allow configuration while XDP is active - differentiate current features from the capable set, to restore on XDP down only those features that were active on XDP up - move test out of VIRTIO_NET_F_CSUM/TSO branch, which is tx only Signed-off-by: Willem de Bruijn Acked-by: Michael S.

The skb is then passed to ip_route_output_key_hash_rcu() which might call into the flow dissector in case a multipath route was hit and a nexthop needs to be selected based on the multipath hash. Since both 'skb->dev' and 'skb->sk' are not set, a warning is triggered in the flow dissector [1]. The warning is there to prevent codepaths from silently falling back to the standard flow dissector instead of the BPF one. Therefore, instead of removing the warning, set 'skb->dev' to the loopback device, as its not used for anything but resolving the correct namespace.

For fadump to work successfully there should not be any holes in reserved memory ranges where kernel has asked firmware to move the content of old kernel memory in event of crash. Now that fadump uses CMA for reserved area, this memory area is now not protected from hot-remove operations unless it is cma allocated. Hence, fadump service can fail to re-register after the hot-remove operation, if hot-removed memory belongs to fadump reserved region. To avoid this make sure that memory from fadump reserved area is not hot-removable if fadump is registered. However, if user still wants to remove that memory, he can do so by manually stopping fadump service before hot-remove operation.

On large systems with TeraBytes of memory, this reservation can be quite significant. In some cases, fadump fails if the memory reserved is insufficient, or if the reserved memory was DLPAR hot-removed. In the normal case, post reboot, the preserved memory is filtered to extract only relevant areas of interest using the makedumpfile tool. While the tool provides flexibility to determine what needs to be part of the dump and what memory to filter out, all supported distributions default this to "Capture only kernel data and nothing else". We take advantage of this default and the Linux kernel's Contiguous Memory Allocator (CMA) to fundamentally change the memory reservation model for fadump. Instead of setting aside a significant chunk of memory nobody can use, this patch uses CMA instead, to reserve a significant chunk of memory that the kernel is prevented from using (due to MIGRATE_CMA), but applications are free to use it. With this fadump will still be able to capture all of the kernel memory and most of the user space memory except the user pages that were present in CMA region. Essentially, on a P9 LPAR with 2 cores, 8GB RAM and current upstream: [root@zzxx-yy10 ~]# free -m total used free shared buff/cache available Mem: 7557 193 6822 12 541 6725 Swap: 4095 0 4095 With this patch: [root@zzxx-yy10 ~]# free -m total used free shared buff/cache available Mem: 8133 194 7464 12 475 7338 Swap: 4095 0 4095 Changes made here are completely transparent to how fadump has traditionally worked.

So far these are called in correct order (may be we got lucky) and never saw any issue.

In KSZ9477 the member for port 1 is 0x41; port 2, 0x42; port 3, 0x44; port 4, 0x48; port 5, 0x50; and port 7, 0x60. Port 6 is the host port. Setting a zero value can be used to stop port from receiving. However, when UNICAST_VLAN_BOUNDARY is disabled and the unicast addresses are already learned in the dynamic MAC table, setting zero still allows devices connected to those ports to communicate. This does not apply to multicast and broadcast addresses though. To prevent these leaks and make the function of port membership consistent UNICAST_VLAN_BOUNDARY should never be disabled. Note that UNICAST_VLAN_BOUNDARY is enabled by default in KSZ9477.

The first one, in patches #1-#2, relieves the user from the need to configure a VLAN interface and only later the corresponding VXLAN tunnel. The issue is explained in detail in the first patch. The second improvement is described below and allows the user to make use of VID 1 by having the driver use the reserved 4095 VID for untagged traffic. VLAN entries on a given port can be associated with either a bridge or a router. For example, if swp1.10 is assigned an IP address and swp1.20 is enslaved to a VLAN-unaware bridge, then both {Port 1, VID 10} and {Port 1, VID 20} would be associated with a filtering identifier (FID) of the correct type. In case swp1 itself is assigned an IP address or enslaved to a VLAN-unaware bridge, then a FID would be associated with {Port 1, VID 1}. Using VID 1 for this purpose means that VLAN devices with VID 1 cannot be created over mlxsw ports, as this VID is (ab)used as the default VLAN. Instead of using VID 1 for this purpose, we can use VID 4095 which is reserved for internal use and cannot be configured by either the 8021q or the bridge driver. Patches #3-#7 perform small and non-functional changes that finally allow us to switch to VID 4095 as the default VID in patch #8. Patch #9 removes the limitation about creation of VLAN devices with VID 1 over mlxsw ports. Patches #10-#11 add test cases. ==================== Signed-off-by: David S.

In case the VXLAN device is already enslaved to the bridge and only later the VLAN interface is configured, the tunnel will not be offloaded. The reason for this is that when the router interface (RIF) corresponding to the VLAN interface is configured, it calls the core fid_get() API which does not check if NVE should be enabled on the FID. Instead, call into the bridge code which will check if NVE should be enabled on the FID. This effectively means that the same code path is used to retrieve a FID when either a local port or a router port joins the FID.

I replaced spinlocks for mutex locks to reduce the latency on CPU0 for igb when updating the statistics. This work was based off a patch provided by Jan Jablonsky, which was against an older version of the igb driver. Jesus adjusts the receive packet buffer size from 32K to 30K when running in QAV mode, to stay within 60K for total packet buffer size for igb. Vinicius adds igb kernel documentation regarding the CBS algorithm and its implementation in the i210 family of NICs. YueHaibing from Huawei fixed the e100 driver that was potentially passing a NULL pointer, so use the kernel macro IS_ERR_OR_NULL() instead. Konstantin Khorenko fixes i40e where we were not setting up the neigh_priv_len in our net_device, which caused the driver to read beyond the neighbor entry allocated memory. Miroslav Lichvar extends the PTP gettime() to read the system clock by adding support for PTP_SYS_OFFSET_EXTENDED ioctl in i40e. Young Xiao fixed the ice driver to only enable NAPI on q_vectors that actually have transmit and receive rings. Kai-Heng Feng fixes an igb issue that when placed in suspend mode, the NIC does not wake up when a cable is plugged in. This was due to the driver not setting PME during runtime suspend.

Other than the "sk_msg, zap ingress queue on psock down" (PATCH 6/8) which can potentially cause a WARNING the issues fixed in this series do not cause kernel side warnings, BUG, etc. but instead cause stalls and other odd behavior in the user space applications when using kTLS with BPF policies applied. Primarily tested with 'curl' compiled with latest openssl and also 'openssl s_client/s_server' containers using Cilium network plugin with docker/k8s. Some basic testing with httpd was also enabled. Cilium CI tests will be added shortly to cover these cases as well. We also have 'wrk' and other test and benchmarking tools we can run now.

If the application tries to send data after the TLS ULP enable op but before the TLS TX enable op the BPF sk_msg verdict program is skipped. This patch resolves this by converting the ipv4 sock ops to be calculated at init time the same way ipv6 ops are done. This pulls in any changes to the sock ops structure that have been made after the socket was created including the changes from adding the socket to a sock{map|hash}. This was discovered by running OpenSSL master branch which calls the TLS ULP setsockopt early in TLS handshake but only enables the TLS TX path once the handshake has completed. As a result the datapath missed the initial handshake messages.

This fixes the behavior to call through the ULP layer on redirect to ensure any operations required on the data stream at the ULP layer continue to be applied. To do this we add an internal flag MSG_SENDPAGE_NOPOLICY to avoid calling the BPF layer on a redirected message. This is required to avoid calling the BPF layer multiple times (possibly recursively) which is not the current/expected behavior without ULPs. In the future we may add a redirect flag if users _do_ want the policy applied again but this would need to work for both ULP and non-ULP sockets and be opt-in to avoid breaking existing programs. Also to avoid polluting the flag space with an internal flag we reuse the flag space overlapping MSG_SENDPAGE_NOPOLICY with MSG_WAITFORONE. Here WAITFORONE is specific to recv path and SENDPAGE_NOPOLICY is only used for sendpage hooks. The last thing to verify is user space API is masked correctly to ensure the flag can not be set by user. (Note this needs to be true regardless because we have internal flags already in-use that user space should not be able to set). But for completeness we have two UAPI paths into sendpage, sendfile and splice. In the sendfile case the function do_sendfile() zero's flags, ./fs/read_write.c: static ssize_t do_sendfile(int out_fd, int in_fd, loff_t *ppos, size_t count, loff_t max) { ... fl = 0; #if 0 /* * We need to debate whether we can enable this or not. The * man page documents EAGAIN return for the output at least, * and the application is arguably buggy if it doesn't expect * EAGAIN on a non-blocking file descriptor. */ if (in.file->f_flags & O_NONBLOCK) fl = SPLICE_F_NONBLOCK; #endif file_start_write(out.file); retval = do_splice_direct(in.file, &pos, out.file, &out_pos, count, fl); } In the splice case the pipe_to_sendpage "actor" is used which masks flags with SPLICE_F_MORE. ./fs/splice.c: static int pipe_to_sendpage(struct pipe_inode_info *pipe, struct pipe_buffer *buf, struct splice_desc *sd) { ... more = (sd->flags & SPLICE_F_MORE) ?

Now that support for redirects exists we can implement SK_PASS as a redirect to the same socket. This simplifies the BPF programs and avoids an extra map lookup on RX path for simple visibility cases. Further, reduces user (BPF programmer in this context) confusion when their program drops skb due to lack of support.

Further, it doesn't preclude accessing any padding that may be added in the middle of a struct. All told this makes it fragile to rely on. To fix this explicitly check offsets with fields using the bpf_ctx_range() and bpf_ctx_range_till() macros. For reference the current structure layout looks as follows (reported by pahole) struct sk_msg_md { union { void * data; /* 8 */ }; /* 0 8 */ union { void * data_end; /* 8 */ }; /* 8 8 */ __u32 family; /* 16 4 */ __u32 remote_ip4; /* 20 4 */ __u32 local_ip4; /* 24 4 */ __u32 remote_ip6[4]; /* 28 16 */ __u32 local_ip6[4]; /* 44 16 */ __u32 remote_port; /* 60 4 */ /* --- cacheline 1 boundary (64 bytes) --- */ __u32 local_port; /* 64 4 */ __u32 size; /* 68 4 */ /* size: 72, cachelines: 2, members: 10 */ /* last cacheline: 8 bytes */ }; So there should be no padding at the moment but fixing this now prevents future errors.

The fastest way for me to trigger the crash is to do a reboot, resulting in this splat: [ 76.478825] WARNING: CPU: 0 PID: 527 at linux/kernel/workqueue.c:1442 __queue_work+0x2d4/0x41c [ 76.478849] Modules linked in: raspberrypi_hwmon gpio_backlight backlight bcm2835_rng rng_core [last unloaded: tinydrm] [ 76.478916] CPU: 0 PID: 527 Comm: systemd-udevd Not tainted 4.20.0-rc4+ #4 [ 76.478933] Hardware name: BCM2835 [ 76.478949] Backtrace: [ 76.478995] [] (dump_backtrace) from [] (show_stack+0x20/0x24) [ 76.479022] r6:00000000 r5:c0bc73be r4:00000000 r3:6fb5bf81 [ 76.479060] [] (show_stack) from [] (dump_stack+0x20/0x28) [ 76.479102] [] (dump_stack) from [] (__warn+0xec/0x12c) [ 76.479134] [] (__warn) from [] (warn_slowpath_null+0x4c/0x58) [ 76.479165] r9:c0eb6944 r8:00000001 r7:c0e927f8 r6:c0bc73be r5:000005a2 r4:c0139e84 [ 76.479197] [] (warn_slowpath_null) from [] (__queue_work+0x2d4/0x41c) [ 76.479222] r6:d7666a00 r5:c0e918ee r4:dbc4e700 [ 76.479251] [] (__queue_work) from [] (queue_work_on+0x60/0x88) [ 76.479281] r10:c0496bf8 r9:00000100 r8:c0e92ae0 r7:00000001 r6:d9403700 r5:d7666a00 [ 76.479298] r4:20000113 [ 76.479348] [] (queue_work_on) from [] (cursor_timer_handler+0x30/0x54) [ 76.479374] r7:d8a8fabc r6:c0e08088 r5:d8afdc5c r4:d8a8fabc [ 76.479413] [] (cursor_timer_handler) from [] (call_timer_fn+0x100/0x230) [ 76.479435] r4:c0e9192f r3:d758a340 [ 76.479465] [] (call_timer_fn) from [] (expire_timers+0x10c/0x12c) [ 76.479495] r10:40000000 r9:c0e9192f r8:c0e92ae0 r7:d8afdccc r6:c0e19280 r5:c0496bf8 [ 76.479513] r4:d8a8fabc [ 76.479541] [] (expire_timers) from [] (run_timer_softirq+0xa8/0x184) [ 76.479570] r9:00000001 r8:c0e19280 r7:00000000 r6:c0e08088 r5:c0e1a3e0 r4:c0e19280 [ 76.479603] [] (run_timer_softirq) from [] (__do_softirq+0x1ac/0x3fc) [ 76.479632] r10:c0e91680 r9:d8afc020 r8:0000000a r7:00000100 r6:00000001 r5:00000002 [ 76.479650] r4:c0eb65ec [ 76.479686] [] (__do_softirq) from [] (irq_exit+0xe8/0x168) [ 76.479716] r10:d8d1a9b0 r9:d8afc000 r8:00000001 r7:d949c000 r6:00000000 r5:c0e8b3f0 [ 76.479734] r4:00000000 [ 76.479764] [] (irq_exit) from [] (__handle_domain_irq+0x94/0xb0) [ 76.479793] [] (__handle_domain_irq) from [] (bcm2835_handle_irq+0x3c/0x48) [ 76.479823] r8:d8afdebc r7:d8afddfc r6:ffffffff r5:c0e089f8 r4:d8afddc8 r3:d8afddc8 [ 76.479851] [] (bcm2835_handle_irq) from [] (__irq_svc+0x70/0x98) The problem is in the console rebinding in fbcon_fb_unbind().

In most cases this other symbol is an architecture or platform specific symbol, or PCI. Generic symbols and drivers without platform dependencies keep their dependencies on HAS_DMA, to prevent compiling subsystems or drivers that cannot work anyway. This simplifies the dependencies, and allows to improve compile-testing.

Prevent this by mapping the page read-only for userland, and using access_process_vm() with the FOLL_FORCE flag to write to it from mips_dsemul(). This will likely be less efficient due to copy_to_user_page() performing cache maintenance on a whole page, rather than a single line as in the previous use of flush_cache_sigtramp(). However this delay slot emulation code ought not to be running in any performance critical paths anyway so this isn't really a problem, and we can probably do better in copy_to_user_page() anyway in future. A major advantage of this approach is that the fix is small & simple to backport to stable kernels.

The default PA off timings were fine tuned to make proper DFS radar detection in QCA reference design. If ODM uses different PA in their design, then the same default PA off timing values cannot be used, it requires different settling time to detect radar pulses very sooner and avoid radar detection problems. In that case it provides provision to select proper PA off timing values based on the PA hardware used. The PA component is part of FEM hardware and new device tree entry "ext-fem-name" is used to indentify the FEM hardware.

The Front End Module(FEM) normally includes tx power amplifier(PA) and rx low noise amplifier(LNA). The default timing parameters like tx end to PA off timing values were fine tuned for internal FEM used in reference design. And these timing values can not be same if ODM modifies hardware design with different external FEM. This DT entry helps to choose correct timing values in driver if different external FEM hardware used.

When number of sub frames exceeds the limit, target hardware will send all msdus starting from present msdu in RAW format as a single msdu packet and it will be indicated with error status bit "RX_MSDU_END_INFO0_MSDU_LIMIT_ERR" set in rx descriptor. This msdu frame is a partial raw MSDU and does't have first msdu and ieee80211 header. It caused below warning message.

This learning can't be disabled by default in FW since it breaks backward compatibility. Since ath10k uses mac80211 based 4addr mode, source port learning done in 10.4 FW is redundant and also causes issues when 3addr frames are transmitted/received for a 4addr station. One such visible functional impact is when GTK rekey frame from hostapd based AP to 4addr STA is dropped in AP's 10.4 FW. This is since GTK rekey EAPOL frame is 3addr frame on AP interface and STA enabled with 4addr is already allowed for receiving 3addr EAPOL frames. Source port learning implementation in 10.4 FW drops this 3addr GTK rekey frame in AP destinated for 4addr STA causing disassociation and re-association for every GTK rekey session. GTK rekey issue is not seen when learning is disabled in FW. To prevent such issues without breaking backward compatibility, FW advertises new service bit making the source port learning configurable and this learning is being currently disabled during ath10k vdev creation. * Tested HW: QCA9984 * Tested FW: 10.4-3.6.0.1-00004 Signed-off-by: Sathishkumar Muruganandam Signed-off-by: Kalle Valo commit 9a9cf0e63f707303dd4bbd2e14f812b85116b8b5 Author: Anilkumar Kolli Date: Thu Dec 20 09:53:28 2018 +0200 ath10k: report tx rate using ieee80211_tx_rate_update() Mesh path metric needs tx rate information from ieee80211_tx_status() call but in ath10k there is no mechanism to report tx rate information via ieee80211_tx_status(), the tx rate is only accessible via sta_statiscs() op.

With the introduction of REQ_OP_WRITE_ZEROES, we started to use that for both WRITE_ZEROES and DISCARDS, hoping that WRITE_ZEROES would "do what we want", UNMAP if possible, zero-out the rest. The example scenario is some LVM "thin" backend. While an un-allocated block on dm-thin reads as zeroes, on a dm-thin with "skip_block_zeroing=true", after a partial block write allocated that block, that same block may well map "undefined old garbage" from the backends on LBAs that have not yet been written to. If we cannot distinguish between zero-out and discard on the receiving side, to avoid "undefined old garbage" to pop up randomly at later times on supposedly zero-initialized blocks, we'd need to map all discards to zero-out on the receiving side. But that would potentially do a full alloc on thinly provisioned backends, even when the expectation was to unmap/trim/discard/de-allocate. We need to distinguish on the protocol level, whether we need to guarantee zeroes (and thus use zero-out, potentially doing the mentioned full-alloc), or if we want to put the emphasis on discard, and only do a "best effort zeroing" (by "discarding" blocks aligned to discard-granularity, and zeroing only potential unaligned head and tail clippings to at least *try* to avoid "false positives" in an online-verify later), hoping that someone set skip_block_zeroing=false. For some discussion regarding this on dm-devel, see also https://www.mail-archive.com/dm-devel%40redhat.com/msg07965.html https://www.redhat.com/archives/dm-devel/2018-January/msg00271.html For backward compatibility, P_TRIM means zero-out, unless the DRBD_FF_WZEROES feature flag is agreed upon during handshake. To have upper layers even try to submit WRITE ZEROES requests, we need to announce "efficient zeroout" independently. We need to fixup max_write_zeroes_sectors after blk_queue_stack_limits(): if we can handle "zeroes" efficiently on the protocol, we want to do that, even if our backend does not announce max_write_zeroes_sectors itself.

But if we then are *still* connected to a Primary, we fail (after an additional timeout of ping-timout). This change skips the spurious second timeout. Most people won't notice really, since "ping-timeout" by default is half a second. But in some installations, ping-timeout may be 10 or 20 seconds or more, and spuriously delaying the error return becomes annoying.

It can mean "do not allow new requests" (obviously), but it also may mean "must not complete pending IO", for example while the fencing handlers do their arbitration. When adjusting disk options, we suspend io (disallow new requests), then wait for the activity-log to become unused (drain all IO completions), and possibly replace it with a new activity log of different size. If the other "suspend IO" aspect is active, pending IO completions won't happen, and we would block forever (unkillable drbdsetup process). Fix this by skipping the activity log adjustment if the "al-extents" setting did not change. Also, in case it did change, fail early without blocking if it looks like we would block forever.

Because we only compared our "effective" and the "to-be-attached" data generation uuid tags if (device->state.conn < C_CONNECTED). Fix: change that constraint to (device->state.pdsk != D_UP_TO_DATE) compare the uuids, and reject the attach. This patch also tries to improve the reverse scenario: first lose Secondary, then Primary disk, then try to attach the disk on Secondary. Before this patch, the attach on the Secondary succeeds, but since commit drbd: disconnect, if the wrong UUIDs are attached on a connected peer the Primary will notice unsuitable data, and drop the connection hard. Though unfortunately at a point in time during the handshake where we cannot easily abort the attach on the peer without more refactoring of the handshake. We now reject any attach to "unsuitable" uuids, as long as we can see a Primary role, unless we already have access to "good" data.

If we first lost connection to the peer, then later lost connection to our own disk, we would usually refuse to re-connect to the peer, because it presents the wrong data set. However, if the peer first connects without a disk, and then attached its disk, we accepted that same wrong data set, which would be "unexpected" by any user of that DRBD and cause "undefined results" (read: very likely data corruption). The fix is to forcefully disconnect as soon as we notice that the peer attached to the "wrong" dataset.

Which could be zero if that peer was just brought up and connected to us without having a disk attached first, in which case both peers would just "flip" their volume sizes. Now, even a diskless node will ignore "zero" sizes presented by a diskless peer. Also a currently Diskless Primary will refuse to shrink during handshake: it may be frozen, and waiting for a "suitable" local disk or peer to re-appear (on-no-data-accessible suspend-io). If the peer is smaller than what we used to be, it is not suitable. The logic for a diskless node during handshake is now supposed to be: believe the peer, if - I don't have a current size myself - we agree on the size anyways - I do have a current size, am Secondary, and he has the only disk - I do have a current size, am Primary, and he has the only disk, which is larger than my current size Signed-off-by: Lars Ellenberg Signed-off-by: Jens Axboe commit d5412e8d8e6311c09fddcd7f1a4030b8bbe0caf7 Author: Lars Ellenberg Date: Thu Dec 20 17:23:30 2018 +0100 drbd: centralize printk reporting of new size into drbd_set_my_capacity() Previously, some implicit resizes that happend during handshake have not been reported as prominently as explicit resize.

In ath10k_sta_state(), arsta->tx_stats get deallocated before peer deletion when the station moves from IEEE80211_STA_NONE to IEEE80211_STA_NOTEXIST state. 2. Meanwhile ath10k receive HTT_T2H_MSG_TYPE_PEER_STATS message. In ath10k_htt_fetch_peer_stats(), arsta->tx_stats get accessed after the peer validation check. Since arsta->tx_stats get freed before the peer deletion [1]. ath10k_htt_fetch_peer_stats() ended up in "use after free" situation. Fixed this issue by moving the arsta->tx_stats free handling after the peer deletion. so that ath10k_htt_fetch_peer_stats() will not end up in "use after free" situation.

To quote Eric's explanation: [...] mount(..., MS_REMOUNT|MS_BIND, ...) now validates the mount options string, which breaks systemd unit files with ProtectControlGroups=yes (e.g. systemd-networkd.service) when systemd does the following to change a cgroup (v1) mount to read-only: mount(NULL, "/run/systemd/unit-root/sys/fs/cgroup/systemd", NULL, MS_RDONLY|MS_NOSUID|MS_NODEV|MS_NOEXEC|MS_REMOUNT|MS_BIND, NULL) ... when the kernel has CONFIG_CGROUPS=y but no cgroup subsystems enabled, since in that case the error "cgroup1: Need name or subsystem set" is hit when the mount options string is empty. Probably it doesn't make sense to validate the mount options string at all in the MS_REMOUNT|MS_BIND case, though maybe you had something else in mind. This is also worthwhile doing because we will need to add a mount_setattr() syscall to take over the remount-bind function.

Older firmware only supports 16-bit flow handle, because of which the number of flows that can be offloaded can’t scale beyond a point. Newer firmware supports 64-bit flow handle enabling the host to scale upto millions of flows. With the new 64-bit flow handle support, driver has to query flow stats in a different way compared to the older approach. This patch adds support for 64-bit flow handle and new way to query flow stats. Signed-off-by: Venkat Duvvuru Reviewed-by: Sriharsha Basavapatna Signed-off-by: Michael Chan Signed-off-by: David S.

Earlier, some of the firmware commands (ex: CFA_FLOW_*) which are processed by KONG processor were sent to the CHIMP processor from the host. This approach was taken as there was no direct message channel to KONG. CHIMP in turn used to send them to KONG. Newer firmware supports a new message channel which the host can send messages directly to the KONG processor. This patch adds support for required changes needed in the driver to support direct KONG message channel. This speeds up flow related messages sent to the firmware for CLS_FLOWER offload.

Mediatek Preloader is a proprietary embedded boot loader for loading Little Kernel and Linux into device DRAM. This boot loader also handle firmware update. Mediatek Preloader will be enumerated as a virtual COM port when the device is connected to Windows or Linux OS via CDC-ACM class driver. When the USB enumeration has been done, Mediatek Preloader will send out handshake command "READY" to PC actively instead of waiting command from the download tool. Since Linux 4.12, the commit "tty: reset termios state on device registration" (93857edd9829e144acb6c7e72d593f6e01aead66) causes Mediatek Preloader receiving some abnoraml command like "READYXX" as it sent. This will be recognized as an incorrect response. The behavior change also causes the download handshake fail. This change only affects subsequent connects if the reconnected device happens to get the same minor number. By disabling the ECHO termios flag could avoid this problem. However, it cannot be done by user space configuration when download tool open /dev/ttyACM0. This is because the device running Mediatek Preloader will send handshake command "READY" immediately once the CDC-ACM driver is ready. This patch wants to fix above problem by introducing "DISABLE_ECHO" property in driver_info. When Mediatek Preloader is connected, the CDC-ACM driver could disable ECHO flag in termios to avoid the problem.

We also move existing devices to the right location in the l4 interconnect hierarcy. This is similar to what we've already done for omap4 l4 interconnects earlier, and follows what is documented in the ti-sysc driver dts binding in Documentation/devicetree/bindings/bus/ti-sysc.txt. These changes will essentially replace the struct ti_sysc and clock entries in the arch/arm/mach-omap2/omap_hwmod_*_data.c files. Then a few merge windows later, we can start dropping the built-in platform data from the omap_hwmod_*_data.c files in favor of the device tree data only. For now, we verify the device tree data module data against the built-in data and warn about changes to prevent regressions. With the device tree data, we are also probing devices with the ti-sysc interconnect target module instead of omap_device. This fixes up the handling for multiple device instances in a single interconnect target module that has caused trouble earlier. A custom wrapper driver has been needed earlier for such cases. And as the device tree data is organized by the l4 interconnect instances, we will be able to use genpd later on. This is because each interconnect instance is also often also a single power domain. This series of changes has been brewing for several months now. I did not want to send a pull request earlier as people were still seeing device specific issues until recently though. However, it turned out that all the issues were quite trivial to fix. I had missed adding device tree ranges for the l3 data port used on some devices, and I had missed converting the device addresses for a few devices. And some devices like needed fixes for deferred probe handling such as the EHCI PHY for built-in case on omap5. Anyways, in case of trouble, we can easily just revert changes for a single device if needed. * tag 'omap-for-v4.21/dt-ti-sysc-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap: ARM: dts: Cosmetic fix for omap5 USB node names ARM: dts: Fix wrong address for omap5 sata phy ARM: dts: Add missing ranges for dra7 mcasp l3 ports ARM: dts: Fix ranges for am335x epwmss ARM: dts: Fix hsi gdd range for omap4 ARM: dts: Add am335x mcasp with l3 data port ranges ARM: dts: Add missing ranges for am437x mcasp l3 ports ARM: dts: dra7: Move the ti,no-idle quirk on proper gmac node ARM: dts: Revert am335x mcasp ti-sysc changes ARM: dts: omap5: Add l4 interconnect hierarchy and ti-sysc data ARM: dts: Use dra7 mcasp compatible for mcasp instances ARM: dts: dra7: Move l4 child devices to probe them with ti-sysc ARM: dts: dra7: Add l4 interconnect hierarchy and ti-sysc data ARM: dts: am335x: Move l4 child devices to probe them with ti-sysc ARM: dts: am335x: Add l4 interconnect hierarchy and ti-sysc data ARM: dts: am437x: Move l4 child devices to probe them with ti-sysc ARM: dts: am437x: Add l4 interconnect hierarchy and ti-sysc data ARM: dts: dra7: convert to use new clkctrl layout ARM: dts: am43xx: convert to use new clkctrl layout ARM: dts: am33xx: convert to use new clkctrl layout Signed-off-by: Arnd Bergmann commit 54a67c753610a762ec9f5de3a6fda76a3c3bdb8e Author: Mike Rapoport Date: Thu Dec 6 23:13:01 2018 +0200 docs/mm-api: link slab_common.c to "The Slab Cache" section Several functions in mm/slab_common.c have kernel-doc comments, it makes perfect sense to link them to the MM API reference.

With the commit wrap around are allowed within a transfer. The TX FIFO of the geni serial port uses a word size of 4 bytes. In case of a circular buffer wrap within a transfer the driver currently may write an incomplete word to the FIFO, with some bytes containing data from the circular buffer and others being zero. Since the transfer isn't completed yet the zero bytes are sent as if they were actual data. Handle wrap arounds of the TX buffer properly and ensure that words written to the TX FIFO always contain valid data (unless the transfer is completed).

This should not be true of modern platforms where we send IPIs to specific CPUs to wake them up. Remove the pen_release stuff from SoCs that make use of the per-CPU IPI mechanism. The boot_lock is something that was required for ARM development platforms to ensure that the delay calibration worked properly. This is not necessary for modern platforms that have better bus bandwidth and do not need to calibrate the delay loop for secondary cores. Remove the boot_lock entirely. Due to pen_release and boot_lock removal, .smp_prepare_cpus and .smp_boot_secondary STi callbacks must be reworked properly to allow secondary CPU bring up. Secondary CPU is initialized and started by a U-BOOTROM firmware. Secondary CPU is spinning and waiting for a write at cpu_strt_ptr. Writing secondary_startup address at cpu_strt_ptr makes it to jump directly to secondary_startup(). This write must be done in .smp_boot_secondary callback and not in .smp_prepare_cpus as previously, this insures that secondary_data struct is populated in __cpu_up() (stack, pgdir and swapper_pg_dir fields). The IPI in sti_boot_secondary() is useless, so remove it. This patch is the merged of Russell's patch [1] and the rework of .smp_prepare_cpus and .smp_boot_secondary STi callbacks [2].

That commit was proceeded by a commit which added a config option to control use of BOOTX for early debug, ie. PPC_EARLY_DEBUG_BOOTX, and then the update of the defconfigs was intended to not change behaviour by then enabling the new config option. However enabling PPC_EARLY_DEBUG had other consequences, notably causing us to register the udbg console at the end of udbg_early_init(). This means on a system which doesn't have anything that BOOTX can use (most systems), we register the udbg console very early but the bootx code just throws everything away, meaning early boot messages are never printed to the console. What we want to happen is for the udbg console to only be registered later (from setup_arch()) once we've setup udbg_putc, and then all early boot messages will be replayed.

Patch enforce two contraints incase of L2/L3 bus events. 1)Any L2/L3 event when programmed is also expected to program corresponding PMC4 event from that group. 2)PMC4 event should always been programmed first due to group constraint logic limitation For ex. consider these L3 bus events PM_L3_PF_ON_CHIP_MEM (0x460A0), PM_L3_PF_MISS_L3 (0x160A0), PM_L3_CO_MEM (0x260A0), PM_L3_PF_ON_CHIP_CACHE (0x360A0), 1) This is an INVALID group for L3 Bus event monitoring, since it is missing PMC4 event. perf stat -e "{r160A0,r260A0,r360A0}" < > And this is a VALID group for L3 Bus events: perf stat -e "{r460A0,r160A0,r260A0,r360A0}" < > 2) This is an INVALID group for L3 Bus event monitoring, since it is missing PMC4 event. perf stat -e "{r260A0,r360A0}" < > And this is a VALID group for L3 Bus events: perf stat -e "{r460A0,r260A0,r360A0}" < > 3) This is an INVALID group for L3 Bus event monitoring, since it is missing PMC4 event. perf stat -e "{r360A0}" < > And this is a VALID group for L3 Bus events: perf stat -e "{r460A0,r360A0}" < > Patch here implements group constraint logic suggested by Michael Ellerman.

That means we hit that WARN_ON when user space accesses a kernel address. Before that commit this was handled by find_vma() not finding vma for the kernel address and considering that access as bad area access. Avoid the confusing WARN_ON and convert that to a ratelimited printk. With the patch we now get: for load: a.out[5997]: User access of kernel address (c00000000000dea0) - exploit attempt?

The two functions both access a possible shared variable "frame.skb". This shared variable is freed by dev_kfree_skb() in cw1200_upload_beacon(), which is called by cw1200_bss_info_changed(). The free operation is protected by a mutex lock "priv->conf_mutex" in cw1200_bss_info_changed(). In cw1200_hw_scan(), this shared variable is accessed without the protection of the mutex lock "priv->conf_mutex". Thus, concurrency use-after-free bugs may occur. To fix these bugs, the original calls to mutex_lock(&priv->conf_mutex) and mutex_unlock(&priv->conf_mutex) are moved to the places, which can protect the accesses to the shared variable.

If they do, it could cause the function graph tracer to trace functions that it filtered out. Right now it does not cause a problem because there's a test to check if the function graph tracer is attached to the same function as the function tracer, which for now is true. But the function graph tracer is undergoing changes that can make this no longer true which will cause the function graph tracer to trace other functions. For example: # cd /sys/kernel/tracing/ # echo do_IRQ > set_ftrace_filter # mkdir instances/foo # echo ip_rcv > instances/foo/set_ftrace_filter # echo function_graph > current_tracer # echo function > instances/foo/current_tracer Would cause the function graph tracer to trace both do_IRQ and ip_rcv, if the current tests change. As the current tests prevent this from being a problem, this code does not need to be backported. But it does make the code cleaner. Cc: Thomas Gleixner Cc: Borislav Petkov Cc: "H.

This is generally accompanied by this message in the dmesg output: Device offlined - not ready after error recovery Root Cause: The root cause is a "quirk" in the timeout handling in the Linux SCSI layer. The Linux kernel places a 30-second timeout on most media access commands (reads and writes) that it send to device drivers. When a media access command times out, the Linux kernel goes into error recovery mode for the LUN that was the target of the command that timed out. Every command that timed out is kept on a list inside of the Linux kernel to be retried later. The kernel attempts to recover the command(s) that timed out by issuing a LUN reset followed by a TEST UNIT READY. If the LUN reset and TEST UNIT READY commands are successful, the kernel retries the command(s) that timed out. Each SCSI command issued by the kernel has a result field associated with it. This field indicates the final result of the command (success or error). When a command times out, the kernel places a value in this result field indicating that the command timed out. The "quirk" is that after the LUN reset and TEST UNIT READY commands are completed, the kernel checks each command on the timed-out command list before retrying it. If the result field is still "timed out", the kernel treats that command as not having been successfully recovered for a retry. If the number of commands that are in this state are greater than two, the kernel takes the LUN offline. Fix: When our RAIDStack receives a LUN reset, it simply waits until all outstanding commands complete. Generally, all of these outstanding commands complete successfully. Therefore, the fix in the smartpqi driver is to always set the command result field to indicate success when a request completes successfully. This normally isn’t necessary because the result field is always initialized to success when the command is submitted to the driver. So when the command completes successfully, the result field is left untouched. But in this case, the kernel changes the result field behind the driver’s back and then expects the field to be changed by the driver as the commands that timed-out complete.

Prior to issuing this option, all functions on the same chip must be placed in the offline state by the admin. After the reset, all of the instances may be brought online again. The primary purpose of this functionality is to support cases where firmware update required a chip reset but the admin did not want to reboot the machine in order to instantiate the firmware update.

The driver deferred the PLOGI to the port until the mailbox command finishes. When the mailbox command completed it saw the pending port and called the routines to issue the PLOGI. However, it forgot to clear the UNREG_INP state flag, so the PLOGI xmt routine nooped the PLOGI request assuming it needed to wait for the mailbox command. At this point, login would never be re-attempted. Clear UNREG_INP before issuing the deferred PLOGI. Signed-off-by: Dick Kennedy Signed-off-by: James Smart Signed-off-by: Martin K.

Currently, when a trunk link goes down due to some fault, the driver snapshots the fault code. If the link then comes back up, meaning there is no fault, the driver is not clearing the fault code so the sysfs link_state entry reports old/stale data. Revise the logic so that on successful link up the fault code is cleared. Signed-off-by: Dick Kennedy Signed-off-by: James Smart Signed-off-by: Martin K.

This introduced a bug apparent on powerpc64 systems such as the Raptor Talos II that causes the HBA to drop from the PCIe bus under heavy load and being reinitialized after a couple of seconds. It can easily be triggered on affacted systems by using something like fio --name=random-write --iodepth=4 --rw=randwrite --bs=4k --direct=0 \ --size=128M --numjobs=64 --end_fsync=1 fio --name=random-write --iodepth=4 --rw=randwrite --bs=64k --direct=0 \ --size=128M --numjobs=64 --end_fsync=1 a couple of times. In my case I tested it on both a ZFS raidz2 and a btrfs raid6 using LSI 9300-8i and 9400-8i controllers. The fix consists in resembling the write ordering of writeq() by adding a mandatory write memory barrier before device access and a compiler barrier afterwards. The additional MMIO barrier is superfluous. Signed-off-by: Stephan Günther Reported-by: Matt Corallo Acked-by: Sreekanth Reddy Signed-off-by: Martin K.

The change does not work as expected: it makes enabled physical port dependent on target configfs subsystem (the port's parent), something the configfs guarantees anyway. Besides, scheduling work in a worker thread and waiting for the work's completion is not really a valid workaround for the requirement not to call configfs_depend_item from a configfs callback: the call occasionally deadlocks. Thus, removing configfs_depend_item calls does not break anything and fixes the deadlock problem. Signed-off-by: Anatoliy Glagolev Acked-by: Himanshu Madhani Signed-off-by: Martin K.

Instead, this was done in the struct sock sk_destruct function. There is no reason to keep the UMEM reference around when the socket is being orphaned, so in this patch the xdp_put_mem is called in the xsk_release function. This results in that the xsk_destruct function can be removed! Note that, it still holds that a struct xsk_sock reference might still linger in the XSKMAP after the UMEM is released, e.g. if a user does not clear the XSKMAP prior to closing the process. This sock will be in a "released" zombie like state, until the XSKMAP is removed.

This patchset tries to do that by introducing a set of small and mostly non-functional changes in addition to a new test. I have further improvements in mind, but they can be done in a different set. Patch #1 makes sure we correctly sanitize upper devices of a VLAN interface. Patch #2 removes an unexpected behavior from the driver, in which routes configured on a VLAN interface will cease being offloaded after certain operations. Patch #3 is a small cleanup. Patch #4 simplifies the driver by removing reference counting from VLAN entries configured on a port. Patches #5-#6 simplify linking/unlinking from a bridge, especially when LAG and VLAN devices are involved. They make both operations symmetric even when ports are unlinked from a bridged LAG device. Patch #7-#9 make router interface (RIF) deletion more robust by removing reliance on device chain to indicate whether a NETDEV_DOWN event in the inet{,6}addr notification chains should be processed. This is due to the fact that IP addresses can be flushed from a netdev after it was unlinked from its lower device. Patch #10 adds a new test to for valid and invalid configurations over mlxsw ports. Some of the test cases are derived from recent fixes. I expect that more test cases will be added over time. ==================== Signed-off-by: David S.

One of the reasons for leaking a RIF was that at the time when IP addresses were flushed from the respective netdev (prompting the destruction of the RIF), the netdev was no longer a mlxsw upper. This caused the inet{,6}addr notification blocks to ignore the NETDEV_DOWN event and leak the RIF. Instead of checking whether the netdev is our upper when an IP address is removed, we can instead check if the netdev has a RIF configured. To look up a RIF we need to access mlxsw private data, so the patch stores the notification blocks inside a mlxsw struct. This then allows us to use container_of() and extract the required private data. Signed-off-by: Ido Schimmel Reviewed-by: Petr Machata Signed-off-by: David S.

The inet{,6}addr notification blocks are going to resolve 'struct mlxsw_sp' using container_of(), but the functions they call still use mlxsw_sp_lower_get().

This causes each physical port to increase the reference count of the internal representation of the bridge port by calling mlxsw_sp_port_bridge_join(). However, when a port is removed from a LAG, the corresponding leave() function is not called and the reference count is not decremented. This leads to ugly hacks such as mlxsw_sp_bridge_port_should_destroy() that try to understand if the bridge port should be destroyed even when its reference count is not 0. Instead, make sure that when a port is unlinked from a LAG it would see the same events as if the LAG (or its uppers) were unlinked from a bridge. The above is achieved by walking the LAG's uppers when a port is unlinked and calling mlxsw_sp_port_bridge_leave() for each upper that is enslaved to a bridge.

However, this is not actually needed and only complicates things. Instead, the driver should forbid the creation of a VLAN on a port if this VLAN already exists. This would also solve the issue fixed by the mentioned commit. Therefore, remove the get()/put() API and use create()/destroy() instead. One place that needs special attention is VLAN addition in a VLAN-aware bridge via switchdev operations. In case the VLAN flags (e.g., 'pvid') are toggled, then the VLAN entry already exists. To prevent the driver from wrongly returning EEXIST, the driver is changed to check in the prepare phase whether the entry already exists and only returns an error in case it is not associated with the correct bridge port.

This effectively means that when no local ports are member in the FID, the FID is destroyed regardless if the router port is a member in the FID or not. The above can lead to the unexpected behavior in which routes using a VLAN interface as their nexthop device are no longer offloaded after the last local port leaves the corresponding VLAN (FID). Example: # ip -4 route show dev br0.10 192.0.2.0/24 proto kernel scope link src 192.0.2.1 offload # bridge vlan del vid 10 dev swp3 # ip -4 route show dev br0.10 192.0.2.0/24 proto kernel scope link src 192.0.2.1 After the patch, the route is offloaded before and after the VLAN is removed from local port 'swp3', as the RIF corresponding to 'br0.10' continues to exists. In order to remove RIFs' reliance on the underlying FID's reference count, we need to add a reference count to sub-port RIFs, which are RIFs that correspond to physical ports and their uppers (e.g., LAG devices). In this case, each {Port, VID} ('struct mlxsw_sp_port_vlan') needs to hold a reference on the RIF. For example: bond0.10 | bond0 | +-------+ | | swp1 swp2 Both {Port 1, VID 10} and {Port 2, VID 10} will hold a reference on the RIF corresponding to 'bond0.10'. When the last reference is dropped, the RIF will be destroyed. Signed-off-by: Ido Schimmel Reviewed-by: Petr Machata Signed-off-by: David S.

Miller commit 01e661ebfbad40e6280fb8ec25f2861d39ba4387 Author: Tuong Lien Date: Wed Dec 19 09:17:58 2018 +0700 tipc: add trace_events for tipc socket The commit adds the new trace_events for TIPC socket object: trace_tipc_sk_create() trace_tipc_sk_poll() trace_tipc_sk_sendmsg() trace_tipc_sk_sendmcast() trace_tipc_sk_sendstream() trace_tipc_sk_filter_rcv() trace_tipc_sk_advance_rx() trace_tipc_sk_rej_msg() trace_tipc_sk_drop_msg() trace_tipc_sk_release() trace_tipc_sk_shutdown() trace_tipc_sk_overlimit1() trace_tipc_sk_overlimit2() Also, enables the traces for the following cases: - When user creates a TIPC socket; - When user calls poll() on TIPC socket; - When user sends a dgram/mcast/stream message. - When a message is put into the socket 'sk_receive_queue'; - When a message is released from the socket 'sk_receive_queue'; - When a message is rejected (e.g. due to no port, invalid, etc.); - When a message is dropped (e.g. due to wrong message type); - When socket is released; - When socket is shutdown; - When socket rcvq's allocation is overlimit (> 90%); - When socket rcvq + bklq's allocation is overlimit (> 90%); - When the 'TIPC_ERR_OVERLOAD/2' issue happens; Note: a) All the socket traces are designed to be able to trace on a specific socket by either using the 'event filtering' feature on a known socket 'portid' value or the sysctl file: /proc/sys/net/tipc/sk_filter The file determines a 'tuple' for what socket should be traced: (portid, sock type, name type, name lower, name upper) where: + 'portid' is the socket portid generated at socket creating, can be found in the trace outputs or the 'tipc socket list' command printouts; + 'sock type' is the socket type (1 = SOCK_TREAM, ...); + 'name type', 'name lower' and 'name upper' are the service name being connected to or published by the socket. Value '0' means 'ANY', the default tuple value is (0, 0, 0, 0, 0) i.e. the traces happen for every sockets with no filter. b) The 'tipc_sk_overlimit1/2' event is also a conditional trace_event which happens when the socket receive queue (and backlog queue) is about to be overloaded, when the queue allocation is > 90%. Then, when the trace is enabled, the last skbs leading to the TIPC_ERR_OVERLOAD/2 issue can be traced. The trace event is designed as an 'upper watermark' notification that the other traces (e.g. 'tipc_sk_advance_rx' vs 'tipc_sk_filter_rcv') or actions can be triggerred in the meanwhile to see what is going on with the socket queue. In addition, the 'trace_tipc_sk_dump()' is also placed at the 'TIPC_ERR_OVERLOAD/2' case, so the socket and last skb can be dumped for post-analysis.

The benefit for this kind of event is that we can get an early indication about TIPC link loss issue due to timeout, then can do some necessary actions for troubleshooting. For example: To trigger the 'tipc_proto_rcv' when the 'too_silent' event occurs: echo 'enable_event:tipc:tipc_proto_rcv' > \ events/tipc/tipc_link_too_silent/trigger And disable it when TIPC link is reset: echo 'disable_event:tipc:tipc_proto_rcv' > \ events/tipc/tipc_link_reset/trigger b) The 'tipc_link_retrans' or 'tipc_link_bc_ack' event is useful to trace TIPC retransmission issues. In addition, the commit adds the 'trace_tipc_list/link_dump()' at the 'retransmission failure' case. Then, if the issue occurs, the link 'transmq' along with the link data can be dumped for post-analysis. These dump events should be enabled by default since it will only take effect when the failure happens. The same approach is also applied for the faulty case that the validation of protocol message is failed.

Miller commit b4b9771bcbbd5839b0f77aba55e2f85989ed6779 Author: Tuong Lien Date: Wed Dec 19 09:17:56 2018 +0700 tipc: enable tracepoints in tipc As for the sake of debugging/tracing, the commit enables tracepoints in TIPC along with some general trace_events as shown below. It also defines some 'tipc_*_dump()' functions that allow to dump TIPC object data whenever needed, that is, for general debug purposes, ie. not just for the trace_events. The following trace_events are now available: - trace_tipc_skb_dump(): allows to trace and dump TIPC msg & skb data, e.g. message type, user, droppable, skb truesize, cloned skb, etc. - trace_tipc_list_dump(): allows to trace and dump any TIPC buffers or queues, e.g. TIPC link transmq, socket receive queue, etc. - trace_tipc_sk_dump(): allows to trace and dump TIPC socket data, e.g. sk state, sk type, connection type, rmem_alloc, socket queues, etc. - trace_tipc_link_dump(): allows to trace and dump TIPC link data, e.g. link state, silent_intv_cnt, gap, bc_gap, link queues, etc. - trace_tipc_node_dump(): allows to trace and dump TIPC node data, e.g. node state, active links, capabilities, link entries, etc. How to use: Put the trace functions at any places where we want to dump TIPC data or events. Note: a) The dump functions will generate raw data only, that is, to offload the trace event's processing, it can require a tool or script to parse the data but this should be simple. b) The trace_tipc_*_dump() should be reserved for a failure cases only (e.g. the retransmission failure case) or where we do not expect to happen too often, then we can consider enabling these events by default since they will almost not take any effects under normal conditions, but once the rare condition or failure occurs, we get the dumped data fully for post-analysis. For other trace purposes, we can reuse these trace classes as template but different events. c) A trace_event is only effective when we enable it. To enable the TIPC trace_events, echo 1 to 'enable' files in the events/tipc/ directory in the 'debugfs' file system. Normally, they are located at: /sys/kernel/debug/tracing/events/tipc/ For example: To enable the tipc_link_dump event: echo 1 > /sys/kernel/debug/tracing/events/tipc/tipc_link_dump/enable To enable all the TIPC trace_events: echo 1 > /sys/kernel/debug/tracing/events/tipc/enable To collect the trace data: cat trace or cat trace_pipe > /trace.out & To disable all the TIPC trace_events: echo 0 > /sys/kernel/debug/tracing/events/tipc/enable To clear the trace buffer: echo > trace d) Like the other trace_events, the feature like 'filter' or 'trigger' is also usable for the tipc trace_events.

Miller Date: Wed Dec 19 11:21:45 2018 -0800 Merge branch 'sk_buff-add-extension-infrastructure' Florian Westphal says: ==================== sk_buff: add extension infrastructure TL;DR: - objdiff shows no change if CONFIG_XFRM=n && BR_NETFILTER=n - small size reduction when one or both options are set - no changes in ipsec performance Changes since v1: - Allocate entire extension space from a kmem_cache. - Avoid atomic_dec_and_test operation on skb_ext_put() for refcnt == 1 case. (similar to kfree_skbmem() fclone_ref use). This adds an optional extension infrastructure, with ispec (xfrm) and bridge netfilter as first users. The third (future) user is Multipath TCP which is still out-of-tree. MPTCP needs to map logical mptcp sequence numbers to the tcp sequence numbers used by individual subflows. This DSS mapping is read/written from tcp option space on receive and written to tcp option space on transmitted tcp packets that are part of and MPTCP connection. Extending skb_shared_info or adding a private data field to skb fclones doesn't work for incoming skb, so a different DSS propagation method would be required for the receive side. mptcp has same requirements as secpath/bridge netfilter: 1. extension memory is released when the sk_buff is free'd. 2. data is shared after cloning an skb (clone inherits extension) 3. adding extension to an skb will COW the extension buffer if needed. Two new members are added to sk_buff: 1. 'active_extensions' byte (filling a hole), telling which extensions are available for this skb. This has two purposes. a) avoids the need to initialize the pointer. b) allows to "delete" an extension by clearing its bit value in ->active_extensions. While it would be possible to store the active_extensions byte in the extension struct instead of sk_buff, there is one problem with this: When an extension has to be disabled, we can always clear the bit in skb->active_extensions. But in case it would be stored in the extension buffer itself, we might have to COW it first, if we are dealing with a cloned skb. On kmalloc failure we would be unable to turn an extension off. 2. extension pointer, located at the end of the sk_buff. If the active_extensions byte is 0, the pointer is undefined, it is not initialized on skb allocation. This adds extra code to skb clone and free paths (to deal with refcount/free of extension area) but this replaces similar code that manages skb->nf_bridge and skb->sp structs in the followup patches of the series. It is possible to add support for extensions that are not preseved on clones/copies: 1. define a bitmask of all extensions that need copy/cow on clone 2. change __skb_ext_copy() to check ->active_extensions & SKB_EXT_PRESERVE_ON_CLONE 3. set clone->active_extensions to 0 if test is false. This isn't done here because all extensions that get added here need the copy/cow semantics. Last patch converts skb->sp, secpath information gets stored as new SKB_EXT_SEC_PATH, so the 'sp' pointer is removed from skbuff. Extra code added to skb clone and free paths (to deal with refcount/free of extension area) replaces the existing code that does the same for skb->nf_bridge and skb->secpath. I don't see any other in-tree users that could benefit from this infrastructure, it doesn't make sense to add an extension just for the sake of a single flag bit (like skb->nf_trace). Adding a new extension is a good fit if all of the following are true: 1. Data is related to the skb/packet aggregate 2. Data should be freed when the skb is free'd 3. Data is not going to be relevant/needed in normal case (udp, tcp, forwarding workloads, ...) 4. There are no fancy action(s) needed on clone/free, such as callbacks into kernel modules. ==================== Signed-off-by: David S.

Also, secpath_dup doesn't attach the secpath to the skb, it leaves this to the caller. Use secpath_set in places that immediately assign the return value to skb. This allows to remove skb->sp without touching these spots again. secpath_dup can eventually be removed in followup patch. Signed-off-by: Florian Westphal Signed-off-by: David S.

This isn't done here because all extensions that get added here need the copy/cow semantics. v2: Allocate entire extension space using kmem_cache. Upside is that this allows better tracking of used memory, downside is that we will allocate more space than strictly needed in most cases (its unlikely that all extensions are active/needed at same time for same skb). The allocated memory (except the small extension header) is not cleared, so no additonal overhead aside from memory usage. Avoid atomic_dec_and_test operation on skb_ext_put() by using similar trick as kfree_skbmem() does with fclone_ref: If recount is 1, there is no concurrent user and we can free right away.

If the file system did not provide a commit_metadata() hook, it fell back to using sync_inode_metadata(). Unfortunately doesn't work on all file systems. In particular, it doesn't work on ext4 due to how the inode gets journalled --- the VFS writeback code will not always call ext4_write_inode(). So we need to provide our own ext4_nfs_commit_metdata() method which calls ext4_write_inode() directly.

We don't need any data that is not already in 'struct rpc_cred'. 2/ Don't keep these creds in a hash table. When a credential is needed, simply allocate it. When not needed, discard it. This can easily be faster than performing a lookup on a shared hash table. As the lookup can happen during write-out, use a mempool to ensure forward progress. This means that we cannot compare two credentials for equality by comparing the pointers, but we never do that anyway.

SUNRPC has two sorts of credentials, both of which appear as "struct rpc_cred". There are "generic credentials" which are supplied by clients such as NFS and passed in 'struct rpc_message' to indicate which user should be used to authorize the request, and there are low-level credentials such as AUTH_NULL, AUTH_UNIX, AUTH_GSS which describe the credential to be sent over the wires. This patch replaces all the generic credentials by 'struct cred' pointers - the credential structure used throughout Linux. For machine credentials, there is a special 'struct cred *' pointer which is statically allocated and recognized where needed as having a special meaning. A look-up of a low-level cred will map this to a machine credential. Signed-off-by: NeilBrown Acked-by: J.

Rather than keying the access cache with 'struct rpc_cred', use 'struct cred'. Then use cred_fscmp() to compare credentials rather than comparing the raw pointer. A benefit of this approach is that in the common case we avoid the rpc_lookup_cred_nonblock() call which can be slow when the cred cache is large. This also keeps many fewer items pinned in the rpc cred cache, so the cred cache is less likely to get large.

NFS needs to know when a credential is about to expire so that it can modify write-back behaviour to finish the write inside the expiry time. It currently uses functions in SUNRPC code which make use of a fairly complex callback scheme and flags in the generic credientials. As I am working to discard the generic credentials, this has to change. This patch moves the logic into NFS, in part by finding and caching the low-level credential in the open_context. We then make direct cred-api calls on that. This makes the code much simpler and removes a dependency on generic rpc credentials.

The credential passed in rpc_message.rpc_cred is always a generic credential except in one instance. When gss_destroying_context() calls rpc_call_null(), it passes a specific credential that it needs to destroy. In this case the RPC acts *on* the credential rather than being authorized by it. This special case deserves explicit support and providing that will mean that rpc_message.rpc_cred is *always* generic, allowing some optimizations. So add "tk_op_cred" to rpc_task and "rpc_op_cred" to the setup data. Use this to pass the cred down from rpc_call_null(), and have rpcauth_bindcred() notice it and bind it in place.

One of the two expections is when an AUTH_NULL credential is used such as for RPC ping requests. To improve consistency, don't pass an explicit credential in these cases, but instead pass NULL and set a task flag, similar to RPC_TASK_ROOTCREDS, which requests that NULL credentials be used by default.

When NFS creates a machine credential, it is a "generic" credential, not tied to any auth protocol, and is really just a container for the princpal name. This doesn't get linked to a genuine credential until rpcauth_bindcred() is called. The lookup always succeeds, so various places that test if the machine credential is NULL, are pointless. As a step towards getting rid of generic credentials, this patch gets rid of generic machine credentials. The nfs_client and rpc_client just hold a pointer to a constant principal name. When a machine credential is wanted, a special static 'struct rpc_cred' pointer is used. rpcauth_bindcred() recognizes this, finds the principal from the client, and binds the correct credential.

NFSv4 state management tries a root credential when no machine credential is available, as can happen with kerberos. It does this by replacing the cl_machine_cred with a root credential. This means that any user of the machine credential needs to take a lock while getting a reference to the machine credential, which is a little cumbersome. So introduce an explicit cl_root_cred, and never free either credential until client shutdown. This means that no locking is needed to reference these credentials. Future patches will make use of this. This is only a temporary addition. both cl_machine_cred and cl_root_cred will disappear later in the series.

There is one case which deserves some explanation. nfs4_root_machine_cred() calls rpc_lookup_machine_cred() with a NULL principal name which results in not getting a machine credential, but getting a root credential instead. This appears to be what is expected of the caller, and is clearly the result provided by both auth_unix and auth_gss which already ignore the flag.

Now that we have it, it makes sense to use it. This first step just includes a suitable 'struct cred *' pointer in every 'struct auth_cred' and almost every 'struct rpc_cred'. The rpc_cred used for auth_null has a NULL 'struct cred *' as nothing else really makes sense. For rpc_cred, the pointer is reference counted. For auth_cred it isn't. struct auth_cred are either allocated on the stack, in which case the thread owns a reference to the auth, or are part of 'struct generic_cred' in which case gc_base owns the reference, and "acred" shares it.

(2) The head and tail of a memory slot may not cover a full block size, and we have to take care to not map those with block descriptors, since we could expose memory to the guest that the host did not intend to expose. So far, we have been taking care of (1), but not (2), and our commentary describing (1) was somewhat confusing. This commit attempts to factor out the checks of both into a common function, and if we don't pass the check, we won't attempt any PMD mappings for neither hugetlbfs nor THP. Note that we used to only check the alignment for THP, not for hugetlbfs, but as far as I can tell the check needs to be applied to both scenarios.

As part of cleanup during a failed VCPU create 2. As part of freeing the whole VM (struct kvm refcount == 0) In the first case, we cannot have programmed any timers or mapped any IRQs, and therefore we do not have to cancel anything or unmap anything. In the second case, the VCPU will have gone through kvm_timer_vcpu_put, which will have canceled the emulated physical timer's hrtimer, and we do not need to that here as well. We also do not care if the irq is recorded as mapped or not in the VGIC data structure, because the whole VM is going away. That leaves us only with having to ensure that we cancel the bg_timer if we were blocking the last time we called kvm_timer_vcpu_put().

This seems to be because either the __print_symbolic or the tracepoint macros use a variable named idx. Take this chance to update the fields in the tracepoint to reflect the concepts in the arm64 architecture that we pass to the tracepoint and move the exception type table to the same location and header files as the exits code. We also clear out the exception code to 0 for IRQ exits (which translates to UNKNOWN in text) to make it slighyly less confusing to parse the trace output.

The above is part of the header for macro array_index_nospec() in linux/nospec.h Now, in this particular case, if intid evaluates to exactly VGIC_MAX_SPI or to exaclty VGIC_MAX_PRIVATE, the array_index_nospec() macro ends up returning VGIC_MAX_SPI - 1 or VGIC_MAX_PRIVATE - 1 respectively, instead of VGIC_MAX_SPI or VGIC_MAX_PRIVATE, which, based on the original logic: /* SGIs and PPIs */ if (intid <= VGIC_MAX_PRIVATE) return &vcpu->arch.vgic_cpu.private_irqs[intid]; /* SPIs */ if (intid <= VGIC_MAX_SPI) return &kvm->arch.vgic.spis[intid - VGIC_NR_PRIVATE_IRQS]; are valid values for intid.

If the Skylake driver is selected for a specific platform, and the DSP is detected at run-time based on the PCI class/subclass/prog-if information, the legacy HDaudio driver aborts the probe. This will result in a single driver probing and remove the need for modprobe blacklists. Follow-up patches will add a module parameter to bypass the logic if this automatic detection fails, or if the Skylake driver is unable to actually support the platform (firmware authentication, missing topology file, hardware issue, etc). The same mechanism will be used to conflicts generated by the same PCI ID being registered by both legacy HDAuudio and SOF drivers for Intel platforms. In other words SOF will not require changes to the HDaudio legacy.

To make it easy by keeping a script and which will generate the uapi header and syscall table file. This change will also help to unify the implemen- tation across all architectures. The system call table generation script is added in kernel/syscalls directory which contain the scripts to generate both uapi header file and system call table files. The syscall.tbl will be input for the scripts. syscall.tbl contains the list of available system calls along with system call number and corresponding entry point. Add a new system call in this architecture will be possible by adding new entry in the syscall.tbl file. Adding a new table entry consisting of: - System call number. - ABI. - System call name. - Entry point name. syscallhdr.sh and syscalltbl.sh will generate uapi header unistd_32.h and syscall_table.h files respectively. Both .sh files will parse the content syscall.tbl to generate the header and table files. unistd_32.h will be included by uapi/asm/unistd.h and syscall_table.h is included by kernel/syscall_32.S - the real system call table. Please note, this support is only available for 32-bit kernel, not 64-bit kernel. As I came across the 64-bit kernel is not active for long time. ARM, s390 and x86 architecuture does have similar support. I leverage their implementation to come up with a generic solution.

We have to change the value of NR- _syscalls, if we add or delete a system call. One of the patch in this patch series has a script which will generate a uapi header based on syscall.tbl file. The syscall.tbl file contains the total number of system calls information. So we have two option to update NR_sy- scalls value. 1. Update NR_syscalls in asm/unistd.h manually by count- ing the no.of system calls. No need to update NR_sys- calls until we either add a new system call or delete existing system call. 2. We can keep this feature it above mentioned script, that will count the number of syscalls and keep it in a generated file. In this case we don't need to expli- citly update NR_syscalls in asm/unistd.h file. The 2nd option will be the recommended one. For that, I added the __NR_syscalls macro in uapi/asm/unistd_32/64.h along with NR_syscalls which is moved to asm/unistd.h. The macro __NR_syscalls also added for making the name convention same across all architecture. While __NR_sys- calls isn't strictly part of the uapi, having it as part of the generated header to simplifies the implementation. We also need to enclose this macro with #ifdef __KERNEL__ to avoid side effects.

It doesn't submit this bio, it just uses it for maintaining state while setting up clones. Multiple users can access this bio at the same time. This wasn't previously an issue, even if it was a bit iffy, but with the blkg associations it can become one. We setup the blkg association, then clone bio's and submit, then remove the blkg assocation again. But since we can have multiple tasks doing this at the same time, against multiple blkg's, then we can either lose references to a blkg, or put it twice. The latter causes complaints on the percpu ref being <= 0 when released, and can cause use-after-free as well.

Greg pointed me at sysfs_break_active_protection(), used by the scsi subsystem to allow a sysfs file to unbind itself. That would be a real deadlock, which isn't what's happening here. Also, breaking the active protection means we'd need to manually handle all the lifetime fun. - With Rafael we discussed the task_work approach, which kinda works, but has two downsides: It's a functional change for a lockdep annotation issue, and it won't work for the bind file (which needs to get the errno from the driver load function back to userspace). - Greg also asked why this never showed up: To hit this you need to unregister a 2nd driver from the unload code of your first driver. I guess only gpus do that. The bug has always been there, but only with a recent patch series did we add more locks so that lockdep built a chain from unbinding the snd-hda driver to the acpi_video_unregister call.

Many of these tools are based on LibTooling (https://clang.llvm.org/docs/LibTooling.html), which depends on a database of compiler flags. The standard container for this database is compile_commands.json, which consists of a list of JSON objects, each with "directory", "file", and "command" fields. Some build systems, like cmake or bazel, produce this compilation information directly. Naturally, Makefiles don't. However, the kernel makefiles already create ..o.cmd files that contain all the information needed to build a compile_commands.json file. So, this commit adds scripts/gen_compile_commands.py, which recursively searches through a directory for ..o.cmd files and extracts appropriate compile commands from them. It writes a compile_commands.json file that LibTooling-based tools can use. By default, gen_compile_commands.py starts its search in its working directory and (over)writes compile_commands.json in the working directory. However, it also supports --output and --directory flags for out-of-tree use. Note that while gen_compile_commands.py enables the use of clang-based tools, it does not require the kernel to be compiled with clang. E.g., the following sequence of commands produces a compile_commands.json file that works correctly with LibTooling. make defconfig make scripts/gen_compile_commands.py Also note that this script is written to work correctly in both Python 2 and Python 3, so it does not specify the Python version in its first line. For an example of the utility of this script: after running gen_compile_commands.json on the latest kernel version, I was able to use Vim + the YouCompleteMe pluging + clangd to automatically jump to definitions and declarations. Obviously, cscope and ctags provide some of this functionality; the advantage of supporting LibTooling is that it opens the door to many other clang-based tools that understand the code directly and do not rely on regular expressions and heuristics. Tested: Built several recent kernel versions and ran the script against them, testing tools like clangd (for editor/LSP support) and clang-check (for static analysis). Also extracted some test .cmd files from a kernel build and wrote a test script to check that the script behaved correctly with all permutations of the --output and --directory flags.

This unit uses DM1500 ASIC produced ArchWave AG (formerly known as BridgeCo AG). I note that this model supports three modes in the number of data channels in tx/rx streams; 8 ch pairs, 10 ch pairs, 18 ch pairs. The mode is switched by Vendor-dependent AV/C command, like: $ cd linux-firewire-utils $ ./firewire-request /dev/fw1 fcp 0x00ff000003dbeb0600000000 (8ch pairs) $ ./firewire-request /dev/fw1 fcp 0x00ff000003dbeb0601000000 (10ch pairs) $ ./firewire-request /dev/fw1 fcp 0x00ff000003dbeb0602000000 (18ch pairs) When switching between different mode, the unit disappears from IEEE 1394 bus, then appears on the bus with different combination of stream formats. In a mode of 18 ch pairs, available sampling rate is up to 96.0 kHz, else up to 192.0 kHz. $ ./hinawa-config-rom-printer /dev/fw1 { 'bus-info': { 'adj': False, 'bmc': True, 'chip_ID': 21474898341, 'cmc': True, 'cyc_clk_acc': 100, 'generation': 2, 'imc': True, 'isc': True, 'link_spd': 2, 'max_ROM': 1, 'max_rec': 512, 'name': '1394', 'node_vendor_ID': 987, 'pmc': False}, 'root-directory': [ ['HARDWARE_VERSION', 19], [ 'NODE_CAPABILITIES', { 'addressing': {'64': True, 'fix': True, 'prv': False}, 'misc': {'int': False, 'ms': False, 'spt': True}, 'state': { 'atn': False, 'ded': False, 'drq': True, 'elo': False, 'init': False, 'lst': True, 'off': False}, 'testing': {'bas': False, 'ext': False}}], ['VENDOR', 987], ['DESCRIPTOR', 'Apogee Electronics'], ['MODEL', 126702], ['DESCRIPTOR', 'Ensemble'], ['VERSION', 5297], [ 'UNIT', [ ['SPECIFIER_ID', 41005], ['VERSION', 65537], ['MODEL', 126702], ['DESCRIPTOR', 'Ensemble']]], [ 'DEPENDENT_INFO', [ ['SPECIFIER_ID', 2037], ['VERSION', 1], [(58, 'IMMEDIATE'), 16777159], [(59, 'IMMEDIATE'), 1048576], [(60, 'IMMEDIATE'), 16777159], [(61, 'IMMEDIATE'), 6291456]]]]} Signed-off-by: Takashi Sakamoto Signed-off-by: Takashi Iwai commit 5ae4f61f012a097df93de2285070ec8e34716d29 Author: Gustavo A.

The general interrupts get the default affinity mask assigned while the device queue interrupts are spread out over the possible CPUs. Treating the general interrupts as managed is both a limitation and under certain circumstances a bug. Assume the following situation: default_irq_affinity = 4..7 So if CPUs 4-7 are offlined, then the core code will shut down the device management interrupts because the last CPU in their affinity mask went offline. It's also a limitation because it's desired to allow manual placement of the general device interrupts for various reasons. If they are marked managed then the interrupt affinity setting from both user and kernel space is disabled. That limitation was reported by Kashyap and Sumit. Expand struct irq_affinity_desc with a new bit 'is_managed' which is set for truly managed interrupts (queue interrupts) and cleared for the general device interrupts.

The core interrupt descriptor allocation also decides based on the pointer being non NULL whether an interrupt is managed or not. Devices which use managed interrupts usually have two classes of interrupts: - Interrupts for multiple device queues - Interrupts for general device management Currently both classes are treated the same way, i.e. as managed interrupts. The general interrupts get the default affinity mask assigned while the device queue interrupts are spread out over the possible CPUs. Treating the general interrupts as managed is both a limitation and under certain circumstances a bug. Assume the following situation: default_irq_affinity = 4..7 So if CPUs 4-7 are offlined, then the core code will shut down the device management interrupts because the last CPU in their affinity mask went offline. It's also a limitation because it's desired to allow manual placement of the general device interrupts for various reasons. If they are marked managed then the interrupt affinity setting from both user and kernel space is disabled. To remedy that situation it's required to convey more information than the cpumasks through various interfaces related to interrupt descriptor allocation. Instead of adding yet another argument, create a new data structure 'irq_affinity_desc' which for now just contains the cpumask. This struct can be expanded to convey auxilliary information in the next step. No functional change, just preparatory work.

This implies that the minimum time before autosuspending a device is in the range of 1 tick included to 2 ticks excluded -On arm64 this means between 4ms and 8ms with default jiffies configuration -And on arm, it is between 10ms and 20ms These values are quite high for embedded systems which sometimes want the duration to be in the range of 1 ms. It is possible to switch autosuspend over to using hrtimers to get finer granularity for short durations and take advantage of slack to retain some margins and get long timeouts with minimum wakeups. On an arm64 platform that uses 1ms for autosuspending timeout of its GPU, idle power is reduced by 10% with hrtimer. The latency impact on arm64 hikey octo cores is: - mark_last_busy: from 1.11 us to 1.25 us - rpm_suspend: from 15.54 us to 15.38 us [Only the code path of rpm_suspend() that starts hrtimer has been measured.] arm64 image (arm64 default defconfig) decreases by around 3KB with following details: $ size vmlinux-timer text data bss dec hex filename 12034646 6869268 386840 19290754 1265a82 vmlinux $ size vmlinux-hrtimer text data bss dec hex filename 12030550 6870164 387032 19287746 1264ec2 vmlinux The latency impact on arm 32bits snowball dual cores is : - mark_last_busy: from 0.31 us usec to 0.77 us - rpm_suspend: from 6.83 us to 6.67 usec The increase of the image for snowball platform that I used for testing performance impact, is neglictable (244B). $ size vmlinux-timer text data bss dec hex filename 7157961 2119580 264120 9541661 91981d build-ux500/vmlinux size vmlinux-hrtimer text data bss dec hex filename 7157773 2119884 264248 9541905 919911 vmlinux-hrtimer And arm 32bits image (multi_v7_defconfig) increases by around 1.7KB with following details: $ size vmlinux-timer text data bss dec hex filename 13304443 6803420 402768 20510631 138f7a7 vmlinux $ size vmlinux-hrtimer text data bss dec hex filename 13304299 6805276 402768 20512343 138fe57 vmlinux Signed-off-by: Vincent Guittot Reviewed-by: Ulf Hansson Signed-off-by: Rafael J.

This DMA pool will be freed eventually through the callback function scif_prog_signal_cb() with the parameter of 'status', which actually points to the start of DMA pool. Specifically, in scif_prog_signal_cb(), the 'ep' field and the 'src_dma_addr' field of 'status' are used to free the DMA pool by invoking dma_pool_free(). Given that 'status' points to the start address of the DMA pool, both 'status->ep' and 'status->src_dma_addr' are in the DMA pool. And so, the device has the permission to access them. Even worse, a malicious device can modify them. As a result, dma_pool_free() will not succeed. To avoid the above issue, this patch introduces a new data structure, i.e., scif_cb_arg, to store the arguments required by the call back function. A variable 'cb_arg' is allocated in _scif_prog_signal() to pass the arguments. 'cb_arg' will be freed after dma_pool_free() in scif_prog_signal_cb().

The LPO clock is also added to the WiFi side's power sequencing node if it's missing, to correctly represent the shared connections. There is also a PCM connection for Bluetooth, but this is not covered in this patch. These boards all have a WiFi+BT module from AMPAK, which contains one or two Broadcom chips, depending on the model. The older AP6210 contains two, while the newer AP6212 and AP6330 contain just one, as they use two-in-one combo chips. The Bluetooth side of the module is always connected to a UART on the same pingroup as the SDIO pins for the WiFi side, in a 4 wire configuration. Power to the VBAT and VDDIO pins are provided either by the PMIC, using one or several of its regulator outputs, or other fixed regulators on the board. The VBAT and VDDIO pins are shared with the WiFi side, which would correspond to vmmc-supply and vqmmc-supply in the mmc host node. A clock output from the SoC or the external X-Powers RTC provides the LPO low power clock at 32.768 kHz. All the boards covered in this patch are ones that do not require extra changes to the SoC's dtsi file. For the remaining boards that I have worked on, properties or device nodes for the LPO clock's source are missing. For the Cubietruck, the LPO clock is fed from CLK_OUT_A, which needs to be muxed on pin PI12. This can be represented in multiple ways. This patch puts the pinctrl property in the pin controller node. This is due to limitations in Linux, where pinmux settings, even the same one, can not be shared by multiple devices. Thus we cannot put it in both the WiFi and Bluetooth device nodes. Putting it the CCU node is another option, but Linux's CCU driver does not handle pinctrl. Also the pin controller is guaranteed to be initialized after the CCU, when clocks are available. And any other devices that use muxed pins are guaranteed to be initialized after the pin controller. Thus having the CLK_OUT_A pinmux reference be in the pin controller node is a good choice without having to deal with implementation issues.

Each ipc namespace will mount a new binderfs instance. Mounting binderfs multiple times at different locations in the same ipc namespace will not cause a new super block to be allocated and hence it will be the same filesystem instance. Each new binderfs mount will have its own set of binder devices only visible in the ipc namespace it has been mounted in. All devices in a new binderfs mount will follow the scheme binder%d and numbering will always start at 0. /* Backwards compatibility */ Devices requested in the Kconfig via CONFIG_ANDROID_BINDER_DEVICES for the initial ipc namespace will work as before. They will be registered via misc_register() and appear in the devtmpfs mount. Specifically, the standard devices binder, hwbinder, and vndbinder will all appear in their standard locations in /dev. Mounting or unmounting the binderfs mount in the initial ipc namespace will have no effect on these devices, i.e. they will neither show up in the binderfs mount nor will they disappear when the binderfs mount is gone. /* binder-control */ Each new binderfs instance comes with a binder-control device. No other devices will be present at first. The binder-control device can be used to dynamically allocate binder devices. All requests operate on the binderfs mount the binder-control device resides in. Assuming a new instance of binderfs has been mounted at /dev/binderfs via mount -t binderfs binderfs /dev/binderfs. Then a request to create a new binder device can be made as illustrated in [2]. Binderfs devices can simply be removed via unlink(). /* Implementation details */ - dynamic major number allocation: When binderfs is registered as a new filesystem it will dynamically allocate a new major number. The allocated major number will be returned in struct binderfs_device when a new binder device is allocated. - global minor number tracking: Minor are tracked in a global idr struct that is capped at BINDERFS_MAX_MINOR. The minor number tracker is protected by a global mutex. This is the only point of contention between binderfs mounts. - struct binderfs_info: Each binderfs super block has its own struct binderfs_info that tracks specific details about a binderfs instance: - ipc namespace - dentry of the binder-control device - root uid and root gid of the user namespace the binderfs instance was mounted in - mountable by user namespace root: binderfs can be mounted by user namespace root in a non-initial user namespace. The devices will be owned by user namespace root. - binderfs binder devices without misc infrastructure: New binder devices associated with a binderfs mount do not use the full misc_register() infrastructure. The misc_register() infrastructure can only create new devices in the host's devtmpfs mount. binderfs does however only make devices appear under its own mountpoint and thus allocates new character device nodes from the inode of the root dentry of the super block. This will have the side-effect that binderfs specific device nodes do not appear in sysfs. This behavior is similar to devpts allocated pts devices and has no effect on the functionality of the ipc mechanism itself.

One of the rules associated with fdget() is that ksys_close() must not be called between the fdget() and the fdput(). There is a case where this requirement is not met in the binder driver which results in the reference count dropping to 0 when the device is still in use. This can result in use-after-free or other issues. If userpace has passed a file-descriptor for the binder driver using a BINDER_TYPE_FDA object, then kys_close() is called on it when handling a binder_ioctl(BC_FREE_BUFFER) command. This violates the assumptions for using fdget(). The problem is fixed by deferring the close using task_work_add(). A new variant of __close_fd() was created that returns a struct file with a reference. The fput() is deferred instead of using ksys_close().

The two functions both access a possible shared variable "hep->hcpriv". This shared variable is freed by r8a66597_endpoint_disable() via the call path: r8a66597_endpoint_disable kfree(hep->hcpriv) (line 1995 in Linux-4.19) This variable is read by r8a66597_urb_enqueue() via the call path: r8a66597_urb_enqueue spin_lock_irqsave(&r8a66597->lock) init_pipe_info enable_r8a66597_pipe pipe = hep->hcpriv (line 802 in Linux-4.19) The read operation is protected by a spinlock, but the free operation is not protected by this spinlock, thus a concurrency use-after-free bug may occur. To fix this bug, the spin-lock and spin-unlock function calls in r8a66597_endpoint_disable() are moved to protect the free operation.

This is reasonable but not practical because Sink may not support wide range of voltage when sinking power while Source could advertise its capabilities in relatively wider range. For example, a Source PDO advertising 3.3V-11V@3A (9V Prog of Fixed Nominal Voltage) will not be selected if the Sink requires 5V-12V@3A PPS power. However, the Sink could work well if the requested voltage range in RDOs is 5V-11V@3A. Currently accepted: |--------- source -----| |----------- sink ---------------| Currently not accepted: |--------- source -----| |----------- sink ---------------| |--------- source -----| |----------- sink ---------------| |--------- source -----------------| |------ sink -------| To improve the usability, change the matching rules to what listed below: a. The Source PDO is selectable if any portion of the voltage range overlaps one of the Sink PDO's voltage range. b.

Testing has shown it drops back to communicating at 115200 bps and sends sync-request packages, indicating it has been fully reset. This commit fixes this by queueing a reprobe on resume. This mirrors how USB RTL BT devices, which have the same problem, are handled in the btusb driver, there we set the USB_QUIRK_RESET_RESUME for all RTL devices, which also causes a reprobe on resume. The only difference is that here we need to do the reprobe ourselves. Since we are doing a full reprobe on resume now, we can also turn off the device on suspend to save power while suspended.

Both chips also have an internal power-on-reset, which holds the chip in reset for a short time after the regulators are enabled. For the BCM20702, the time period from when the regulators are enabled, until the chip settles and comes out of sleep state, is 6564 ~ 8171 us. For the BCM43438, the graph only shows the time period from when the regulators are enabled until the chip responds by driving the host's CTS line low, assuming the host has already driven its RTS line low. This is shown to be 6.5 sleep cycles, with the sleep clock at 32.768 kHz. This is around 2 ms. Wait a full 10 ms after the regulators are enabled to account for signal rising times.

First we try the new name "txco", then fall back to the old name "extclk", and finally try retrieving a clock without using any name, to cover any instances where a bad device tree or firmware worked by accident. In the last case, we should take care that we don't get the same clock twice when we add support for the "lpo" clock.

This is redundant if the goal is simply to ignore the errors, thereby making the clk optional. The clk consumer API already checks if the pointer is NULL or not. Simplify the code a bit by assigning NULL to the clk pointer if the error condition is one we want to ignore, which is every error except deferred probing.

When the SK_MSG program is running under an application that is using sendfile the data is not copied into sk_msg buffers by default. Rather the BPF program uses sk_msg_pull_data to read the bytes in. This avoids doing the costly memcopy instructions when they are not in fact needed. However, if we don't know the size of the sk_msg we have to guess if needed bytes are available by doing a pull request which may fail. By including the size of the sk_msg BPF programs can check the size before issuing sk_msg_pull_data requests. Additionally, the same applies for sendmsg calls when the application provides multiple iovs. Here the BPF program needs to pull in data to update data pointers but its not clear where the data ends without a size parameter. In many cases "guessing" is not easy to do and results in multiple calls to pull and without bounded loops everything gets fairly tricky. Clean this up by including a u32 size field. Note, all writes into sk_msg_md are rejected already from sk_msg_is_valid_access so nothing additional is needed there.

We should never receive an interrupt in one of these states, but better play safe. phy_stop(): Just return and print a warning if PHY is in a non-started state.

However this doesn't happen for some cases. The reason is verifier is not clearing slot_type STACK_SPILL for all bytes, it only clears part of them, while verifier is using: slot_type[0] == STACK_SPILL as a convention to check one slot is ptr type. So, the consequence of partial clearing slot_type is verifier could treat a partially overridden ptr slot, which should now be a SCALAR_VALUE slot, still as ptr slot, and rejects some valid programs.

When it's called from amdgpu_dm_atomic_commit_tail during a typical atomic commit the plane state has been swapped so it calls cleanup_fb on the old plane state. However, in the asynchronous commit codepath the call to drm_atomic_helper_commit also calls dm_plane_helper_cleanup_fb after atomic_async_update has been called. Since the plane state is updated in place and has not been swapped the cleanup_fb call affects the new plane state. This results in a use after free for the given sequence: - Fast update, fb1 pin/ref, fb1 unpin/unref - Fast update, fb2 pin/ref, fb2 unpin/unref - Slow update, fb1 pin/ref, fb2 unpin/unref - Fast update, fb2 pin/ref -> use after free. bug [How] Disallow framebuffer changes in the fast path. Since this includes a NULL framebuffer, this means that only framebuffers that have been previously pin+ref at least once will be used, preventing a use after free. This has a significant throughput reduction for cursor updates where the framebuffer changes.

This isn't right: the workaround is trying to make sure that the NONSTOP timer is used for sched_clock in order to keep that clock ticking consistently over a suspend/resume cycle. (Otherwise sched_clock simply stops during suspend and continues after resume). This will notably affect any timetstamped debug prints, so that they show the absolute number of seconds since the system was booted and does not loose wall-clock time during suspend and resume as if time stood still. The real way to fix this problem is to make sched_clock take advantage of any NONSTOP clock source on the system and adjust accordingly, not to try to work around this by using a different sched_clock depending on what system we are compiling for. This can solve the problem for everyone instead of providing a local solution.

The Nomadik MTU timer which has higher precision will be used when the system is up and running, thanks to the recent changes properly utilizing the suspend clocksources. This was discussed back in 2011 when the driver was written, but the infrastructure was not available upstream to use this timer properly. Now the infrastructure is there, so let's finalize the work.

This is a change in behavior from before the fixed patch. The GID entry should be removed from the hardware when GID entry deletion is requested. This allows the driver terminate ongoing traffic through the RoCE GID. While a GID is deleted from the hardware, GID slot in the software GID cache is not freed. GID slot is freed once all references of such GID are dropped. This continue to ensure that such GID slot of hardware is not allocated to new GID entry allocation request. It is allocated once all references to GID entry drop. This approach allows drivers to put a tombestone of some kind on the HW GID index to block the traffic.

Several ioctl structs change size between native 32-bit (ia32) and x32 applications, because x32 follows the native 64-bit (amd64) integer alignment rules and uses 64-bit time_t. In these instances, the ioctl number changes so userspace simply gets -ENOTTY. This scenario can be handled by simply adding more cases. Looking at the different ioctls implemented here: - All the ones marked 'No size or alignment issue on any arch' should presumably all be fine. - All the ones under BROKEN_X86_ALIGNMENT are different under integer alignment rules. Since x32 matches amd64 here, we just need both sets of cases handled. - XFS_IOC_SWAPEXT has both integer alignment differences and time_t differences. Since x32 matches amd64 here, we need to add a case which calls the native implementation. - The remaining ioctls have neither 64-bit integers nor time_t, so x32 matches ia32 here and no change is required at this level. The bulkstat ioctl implementations have some pointer chasing which is handled separately. Signed-off-by: Nick Bowler Reviewed-by: Darrick J. Wong Signed-off-by: Darrick J. Wong commit 7ca860e3c1a74ad6bd8949364073ef1044cad758 Author: Nick Bowler Date: Mon Dec 17 09:35:27 2018 -0800 xfs: Fix bulkstat compat ioctls on x32 userspace. The bulkstat family of ioctls are problematic on x32, because there is a mixup of native 32-bit and 64-bit conventions. The xfs_fsop_bulkreq struct contains pointers and 32-bit integers so that matches the native 32-bit layout, and that means the ioctl implementation goes into the regular compat path on x32. However, the 'ubuffer' member of that struct in turn refers to either struct xfs_inogrp or xfs_bstat (or an array of these). On x32, those structures match the native 64-bit layout. The compat implementation writes out the 32-bit version of these structures. This is not the expected format for x32 userspace, causing problems. Fortunately the functions which actually output these xfs_inogrp and xfs_bstat structures have an easy way to select which output format is required, so we just need a little tweak to select the right format on x32.

While inspecting the ioctl implementations, I noticed that the compat implementation of XFS_IOC_ATTRLIST_BY_HANDLE does not do exactly the same thing as the native implementation. Specifically, the "cursor" does not appear to be written out to userspace on the compat path, like it is on the native path. This adjusts the compat implementation to copy out the cursor just like the native implementation does. The attrlist cursor does not require any special compat handling. This fixes xfstests xfs/269 on both IA-32 and x32 userspace, when running on an amd64 kernel.

This patch locks the superblock ->s_umount sem. in exclusive mode for all Q_XQUOTAON/OFF quotactls too in addition to Q_QUOTAON/OFF. AFAICT, other than ext4, only xfs and ocfs2 are affected by this change. The VFS will now call in xfs_quota_* functions with s_umount held, which wasn't the case before.

Currently the frontends which implement similar code for sharing big buffers between frontend and backend are para-virtualized DRM and sound drivers. Both define the same way to share grant references of a data buffer with the corresponding backend with little differences. Move shared code into a helper module, so there is a single implementation of the same functionality for all. This patch introduces code which is used by sound and display frontend drivers without functional changes with the intention to remove shared code from the corresponding drivers.

Do not request for hwspinlock during the exti driver init since the hwspinlock driver is not probed yet at that stage and the exti driver does not support deferred probe. Instead of this, postpone the hwspinlock request at the first time the hwspinlock is actually needed. Use the hwspin_trylock_raw() API which is the most appropriated here Indeed: - hwspin_lock_() calls are under spin_lock protection (chip_data->rlock or gc->lock). - the _timeout() API relies on jiffies count which won't work if IRQs are disabled which is the case here (a large part of the IRQ setup is done atomically (see irq/manage.c)) As a consequence implement the retry/timeout lock from here. And since all of this is done atomically, reduce the timeout delay to 1 ms.

The decoder sets the packet fields 'packet->exc' and 'packet->exc_ret' to indicate the exception packets; but exception packets don't have a dedicated sample type and shares the same sample type CS_ETM_RANGE with normal instruction packets. As a result, the exception packets are taken as normal instruction packets and this introduces confusion in mixing different packet types. Furthermore, these instruction range packets will be processed for branch samples only when 'packet->last_instr_taken_branch' is true, otherwise they will be omitted, this can introduce a mess for exception and exception returning due to not having the complete address range info for context switching. To process exception packets properly, this patch introduces two new sample types: CS_ETM_EXCEPTION and CS_ETM_EXCEPTION_RET; these two types of packets will be handled by cs_etm__exception(). The function cs_etm__exception() forces setting the previous CS_ETM_RANGE packet flag 'prev_packet->last_instr_taken_branch' to true, this matches well with the program flow when the exception is trapped from user space to kernel space, no matter if the most recent flow has branch taken or not; this is also safe for returning to user space after exception handling. After exception packets have their own sample type, the packet fields 'packet->exc' and 'packet->exc_ret' aren't needed anymore, so remove them.

In the first case it causes the insertion of a OCSD_GEN_TRC_ELEM_NO_SYNC in the middle of the tracing stream, but as we were not handling the NO_SYNC element properly this ends up making users miss the discontinuity indications. Though OCSD_GEN_TRC_ELEM_NO_SYNC is different from CS_ETM_TRACE_ON when output from the decoder, both indicate that the trace data is discontinuous; this patch treats OCSD_GEN_TRC_ELEM_NO_SYNC as a trace discontinuity and generates a CS_ETM_DISCONTINUITY packet for it, so cs-etm can handle the discontinuity for this case, finally it saves the last trace data for the previous trace block and restart samples for the new block.

Furthermore, except TRACE_ON element is for discontinuity, NO_SYNC and EO_TRACE also can be used to indicate discontinuity, though they are used for different scenarios for which the trace is interrupted. This patch renames sample type CS_ETM_TRACE_ON to CS_ETM_DISCONTINUITY, firstly the new name describes more closely the purpose of the packet; secondly this is a preparation for other output elements which also cause the trace discontinuity thus they can share the same one packet type.

As a side effect, it also generates branch sample, because the 'etmq->packet' doesn't contains any new coming packet but point to one stale packet after packets swapping, so it wrongly makes synthesize branch samples with stale packet info. We could review below detailed flow which causes issue: Packet1: start_addr=0xffff000008b1fbf0 end_addr=0xffff000008b1fbfc Packet2: start_addr=0xffff000008b1fb5c end_addr=0xffff000008b1fb6c step 1: cs_etm__sample(): sample: ip=(0xffff000008b1fbfc-4) addr=0xffff000008b1fb5c step 2: flush packet in cs_etm__run_decoder(): cs_etm__run_decoder() `-> err = cs_etm__flush(etmq, false); sample: ip=(0xffff000008b1fb6c-4) addr=0xffff000008b1fbf0 Packet1 and packet2 are two continuous packets, when packet2 is the new coming packet, cs_etm__sample() generates branch sample for these two packets and use [packet1::end_addr - 4 => packet2::start_addr] as branch jump flow, thus we can see the first generated branch sample in step 1. At the end of cs_etm__sample() it swaps packets so 'etm->prev_packet'= packet2 and 'etm->packet'=packet1, so far it's okay for branch sample. If packet2 is the last one packet in trace buffer, even there have no any new coming packet, cs_etm__run_decoder() invokes cs_etm__flush() to flush branch stack entries as expected, but it also generates branch samples by taking 'etm->packet' as a new coming packet, thus the branch jump flow is as [packet2::end_addr - 4 => packet1::start_addr]; this is the second sample which is generated in step 2. So actually the second sample is a stale sample and we should not generate it. This patch introduces a new function cs_etm__end_block(), at the end of trace block this function is invoked to only flush branch stack entries and thus can avoid to generate branch sample for stale packet.

In function cs_etm__flush() it swaps packets only when the flag 'etm->synth_opts.last_branch' is true, this means that it will not swap packets if without option '--itrace=il' to generate last branch entries; thus for this case the 'prev_packet' doesn't point to the correct previous packet and the stale packet still will be used to generate sequential sample. Thus if dump trace with 'perf script' command we can see the incorrect flow with the stale packet's address info. This patch corrects packets swapping in cs_etm__flush(); except using the flag 'etm->synth_opts.last_branch' it also checks the another flag 'etm->sample_branches', if any flag is true then it swaps packets so can save correct content to 'prev_packet'. Finally this can fix the wrong program flow dumping issue. The patch has a minor refactoring to use 'etm->synth_opts.last_branch' instead of 'etmq->etm->synth_opts.last_branch' for condition checking, this is consistent with that is done in cs_etm__sample().

With 'perf trace' we want to process the events as they go, without that delay, and doing it that way works well for the common case which is to trace a thread or a workload started by 'perf trace'. So revert back to not using ordered_events but add an option to select that mode so that users can experiment with their particular use case to see if works better, i.e. if the added delay is not a problem and the ordering helps.

However, kvm_arch_vcpu_ioctl_run() also calls need_new_vmid_gen() but does so without taking the read lock. As far as I can tell, this can lead to the same kind of race: VM 0, VCPU 0 VM 0, VCPU 1 ------------ ------------ update_vttbr (vmid 254) update_vttbr (vmid 1) // roll over read_lock(kvm_vmid_lock); force_vm_exit() local_irq_disable need_new_vmid_gen == false //because vmid gen matches enter_guest (vmid 254) kvm_arch.vttbr = : read_unlock(kvm_vmid_lock); enter_guest (vmid 1) Which results in running two VCPUs in the same VM with different VMIDs and (even worse) other VCPUs from other VMs could now allocate clashing VMID 254 from the new generation as long as VCPU 0 is not exiting. Attempt to solve this by making sure vttbr is updated before another CPU can observe the updated VMID generation.

This calls the latter directly for consistency with the rest of the kernel that is moving to the ktime_get_ family of time accessors, as now documented in Documentation/core-api/timekeeping.rst. An open questions is whether we may want to actually call the more accurate ktime_get_real_ts64() for file systems that save high-resolution timestamps in their on-disk format. This would add a small overhead to each update of the inode stamps but lead to inode timestamps to actually have a usable resolution better than one jiffy (1 to 10 milliseconds normally). Experiments on a variety of hardware platforms show a typical time of around 100 CPU cycles to read the cycle counter and calculate the accurate time from that. On old platforms without a cycle counter, this can be signiciantly higher, up to several microseconds to access a hardware clock, but those have become very rare by now. I traced the original addition of the current_kernel_time() call to set the nanosecond fields back to linux-2.5.48, where Andi Kleen added a patch with subject "nanosecond stat timefields". Andi explains that the motivation was to introduce as little overhead as possible back then. At this time, reading the clock hardware was also more expensive when most architectures did not have a cycle counter. One side effect of having more accurate inode timestamp would be having to write out the inode every time that mtime/ctime/atime get touched on most systems, whereas many file systems today only write it when the timestamps have changed, i.e. at most once per jiffy unless something else changes as well. That change would certainly be noticed in some workloads, which is enough reason to not do it without a good reason, regardless of the cost of reading the time. One thing we could still consider however would be to round the timestamps from current_time() to multiples of NSEC_PER_JIFFY, e.g. full milliseconds rather than having six or seven meaningless but confusing digits at the end of the timestamp.

For y2038 compatbility, we are changing the native system call from timespec to __kernel_timespec with a 64-bit time_t (in another patch), and use the existing compat system call on both 32-bit and 64-bit architectures for compatibility with traditional 32-bit user space. As we now have two variants of recvmmsg() for 32-bit tasks that are both different from the variant that we use on 64-bit tasks, this means we also require two compat system calls! The solution I picked is to flip things around: The existing compat_sys_recvmmsg() call gets moved from net/compat.c into net/socket.c and now handles the case for old user space on all architectures that have set CONFIG_COMPAT_32BIT_TIME. A new compat_sys_recvmmsg_time64() call gets added in the old place for 64-bit architectures only, this one handles the case of a compat mmsghdr structure combined with __kernel_timespec. In the indirect sys_socketcall(), we now need to call either do_sys_recvmmsg() or __compat_sys_recvmmsg(), depending on what kind of architecture we are on. For compat_sys_socketcall(), no such change is needed, we always call __compat_sys_recvmmsg(). I decided to not add a new SYS_RECVMMSG_TIME64 socketcall: Any libc implementation for 64-bit time_t will need significant changes including an updated asm/unistd.h, and it seems better to consistently use the separate syscalls that configuration, leaving the socketcall only for backward compatibility with 32-bit time_t based libc. The naming is asymmetric for the moment, so both existing syscalls entry points keep their names, while the new ones are recvmmsg_time32 and compat_recvmmsg_time64 respectively. I expect that we will rename the compat syscalls later as we start using generated syscall tables everywhere and add these entry points.

The state is stuck in a_wait_vrise even after the micro-A cable is detached, which could cause VBUS retention if then the dual-role port is attached to a host port.

We bodge around this in an ad-hoc fashion. Sometimes we explicitly check whether userspace requested a single step, and fake a debug exception from within the kernel. Other times, we advance the HW singlestep state rely on the HW to generate the exception for us. Thus, the observed step behaviour differs for host and guest. Let's make this simpler and consistent by always advancing the HW singlestep state machine when we skip an instruction. Thus we can rely on the hardware to generate the singlestep exception for us, and never need to explicitly check for an active-pending step, nor do we need to fake a debug exception from the guest.

The large number (>150) of internal interrupt sources are managed by an on-board interrupt controller. This driver provides the handling for the interrupt controller. As the codec is accessed via regmap, we can make use of the generic IRQ functionality from regmap to do most of the work. Only around half of the possible interrupt source are currently of interest from the driver so only this subset is defined. Others can be added in future if needed.

Change the corrupting function to actually corrupt the Nth byte no matter in which biovec that index falls. A test device generating two-page bios, atop a flakey device configured to corrupt a byte index on the second page, verified both the failure to corrupt before this patch and the expected corruption after this change.

If the sector_t is 32bit integer (CONFIG_LBDAF is not set), then several device-mapper targets can overflow this offset and validity check is then performed on a wrong offset and a wrong table is activated. See for example (on 32bit without CONFIG_LBDAF) this overflow: # dmsetup create test --table "0 2048 linear /dev/sdg 4294967297" # dmsetup table test 0 2048 linear 8:96 1 This patch adds explicit check for overflow if the offset is sector_t type.

As a result, the kcopyd thread can continue running completed jobs indefinitely, without releasing the CPU, as long as someone keeps submitting new completed jobs through the aforementioned paths. Processing of work items, queued for execution on the same CPU as the currently running kcopyd thread, is thus stalled for excessive amounts of time, hurting performance.

Under certain workloads this can lead to excessive memory usage and workqueue stalls. For example, when creating multiple dm-snapshot targets with a 4K chunk size and then writing to the origin through the page cache. Syncing the page cache causes a large number of BIOs to be issued to the dm-snapshot origin target, which itself issues an even larger (because of the BIO splitting taking place) number of kcopyd jobs. Running the following test, from the device mapper test suite [1], dmtest run --suite snapshot -n many_snapshots_of_same_volume_N , with 8 active snapshots, results in the kcopyd job slab cache growing to 10G.

In particular, the lack of an explicit or implicit limit to the maximum number of in-flight COW jobs. The merging path is not affected because it implicitly limits the in-flight kcopyd jobs to one. Fix these issues by using a semaphore to limit the maximum number of in-flight kcopyd jobs. We grab the semaphore before allocating a new kcopyd job in start_copy() and start_full_bio() and release it after the job finishes in copy_callback(). The initial semaphore value is configurable through a module parameter, to allow fine tuning the maximum number of in-flight COW jobs. Setting this parameter to zero initializes the semaphore to INT_MAX. A default value of 2048 maximum in-flight kcopyd jobs was chosen. This value was decided experimentally as a trade-off between memory consumption, stalling the kernel's workqueues and maintaining a high enough throughput. Re-running the aforementioned test: * Workqueue stalls are eliminated * kcopyd's job slab cache uses a maximum of 130MB * The time taken by the test to write to the snapshot-origin target is reduced from 05m20.48s to 03m26.38s [1] https://github.com/jthornber/device-mapper-test-suite Signed-off-by: Nikos Tsironis Signed-off-by: Ilias Tsitsimpis Signed-off-by: Mike Snitzer commit ef9923739e6d2233dc16aba70b7d81767d85cfcb Author: Shenghui Wang Date: Tue Oct 30 15:35:54 2018 +0800 dm bufio: update comment in dm-bufio.c * Hashtable has been replaced by rbtree to manage buffers.

Similarly, it attempts to mount tracefs if necessary before trying to dump the trace pipe to the console. While mounting file systems on-the-fly can improve user experience, some administrators might prefer to avoid that. Let's add an option to block these mount attempts. Note that it does not prevent automatic mounting of tracefs by debugfs for the "bpftool prog tracelog" command.

The record sizes for {func,line}_info are passed to kernel, and the record sizes for {func,line,jited_line}_info are returned to userspace during bpf_prog_info query. In bpf selftests test_btf.c, when testing whether kernel returns a legitimate {func,line, jited_line)_info rec_size, the test only compares to the minimum allowed size. If the returned rec_size is smaller than the minimum allowed size, it is considered incorrect. The minimum allowed size for these three info sizes are equal to current value of sizeof(struct bpf_func_info), sizeof(struct bpf_line_info) and sizeof(__u64). The original thinking was that in the future when rec_size is increased in kernel, the same test should run correctly. But this sacrificed the precision of testing under the very kernel the test is shipped with, and bpf selftest is typically run with the same repo kernel. So this patch changed the testing of rec_size such that the kernel returned value should be equal to the size defined by tools uapi header bpf.h which syncs with kernel uapi header. Martin discovered a bug in one of rec_size comparisons. Instead of comparing to minimum func_info rec_size 8, it compares to 4. This patch fixed that issue as well.

When STIBP is conditionally enabled, some implementations would benefit from having STIBP always on instead of toggling the STIBP bit through MSR writes. This preference is advertised through a CPUID feature bit. When conditional STIBP support is requested at boot and the CPU advertises STIBP always-on mode as preferred, switch to STIBP "on" support. To show that this transition has occurred, create a new spectre_v2_user_mitigation value and a new spectre_v2_user_strings message. The new mitigation value is used in spectre_v2_user_select_mitigation() to print the new mitigation message as well as to return a new string from stibp_state().

STA ignores these detected radar events since the radar signal can be seen mostly by the AP as well. But in scenarios where a radar signal is seen only at STA, notifying this event to the AP which can trigger a channel switch can be useful. Stations can report such radar events autonomously through Spectrum management (Measurement Report) action frame to its AP. The userspace on processing the report can notify the kernel with the use of the added NL80211_CMD_NOTIFY_RADAR to indicate the detected event and inturn adding the reported channel to NOL.

This issue can reproduced by set kdump option nr_cpus=, and then trigger panic on last socket's thread, for example: taskset -c 26 echo c > /proc/sysrq-trigger Use total_cpus which will not be limited by nr_cpus command line to calculate the value of __max_logical_packages.

Hence, the DWC driver must not make assumptions that one register space can be accessed at a fixed offset from any other register space. To avoid such assumptions, introduce an explicit/separate register pointer for the ATU register space. In particular, the current assumption is not valid for NVIDIA's T194 SoC. The ATU register space is only used on systems that require unrolled ATU access. This property is detected at run-time for host controllers, and when this is detected, this patch provides a default value for atu_base that matches the previous assumption re: register layout. An alternative would be to update all drivers for HW that requires unrolled access to explicitly set atu_base. However, it's hard to tell which drivers would require atu_base to be set. The unrolled property is not detected for endpoint systems, and so any endpoint driver that requires unrolled access must explicitly set the iatu_unroll_enabled flag (none do at present), and so a check is added to require the driver to also set atu_base while at it.

This is similar to imx7d with a few differences: * The PM_Turn_Off bit is exposed through an IOMUX GPR, like all other pcie control bits on 6sx. * The pcie_inbound_axi clk needs to be turned off in suspend. On resume it is restored via resume -> deassert_core_reset -> enable_ref_clk. Most of the resume logic is shared with the initial reset after probe.

This worked fine if a single app existed that registered one callback per netdev of interest. However, if multiple cards are in place and, in turn, multiple apps, then each app may register the same callback with the same identifier to both the netdev's indirect block cb list and to a block's cb list. This can lead to EEXIST errors and/or incorrect cb deletions. Prevent this conflict by using the app pointer as the identifier for netdev indirect block cb registry, allowing each app to register a unique callback per netdev. For block cb registry, the same app may register multiple cbs to the same block if using TC shared blocks. Instead of the app, use the pointer to the allocated cb_priv data as the identifier here. This means that there can be a unique block callback for each app/netdev combo.

This caused segfaults in DCCP lookups because DCCP did not initialize the (addr,port) hashtable. This patch adds said initialization. The only non-trivial issue here is the size of the new hashtable. It seemed reasonable to make it match the size of the port-only hashtable (= INET_LHTABLE_SIZE) that was used previously. Other parameters to inet_hashinfo2_init() match those used in TCP. V2 changes: marked inet_hashinfo2_init as an exported symbol so that DCCP compiles when configured as a module. Tested: syzcaller issues fixed; the second patch in the patchset tests that DCCP lookups work correctly.

When bringing up a device, the code checks to see if the number of MSIX has changed. pci_disable_msix() should be called first before changing the number of reserved NQs/CMPL rings. This ensures that the MSIX vectors associated with the NQs/CMPL rings are still properly mapped when pci_disable_msix() masks the vectors. This patch will prevent errors when RDMA support is added for the new 57500 chips. When the RDMA driver shuts down, the number of NQs is decreased and we must use the new sequence to prevent MSIX errors. Signed-off-by: Michael Chan Signed-off-by: David S.

Add a stat_ctxs parameter to all the relevant resource reservation functions so we can reserve the correct number of stat_ctxs.

While draft-ietf-intarea-gue-06 doesn't explicitly forbid direct encapsulation of UDP in GUE, it probably doesn't make sense to set up GUE this way, and it's currently not even possible to configure this. Skip exception handling if the GUE proto/ctype field is set to the UDP protocol number. Should we need to handle exceptions for UDP-in-GUE one day, we might need to either explicitly set a bound for recursion, or implement a special iterative handling for these cases.

The original design has a couple of issues though. First, the bitfield size is only encoded in int type. If the struct member bitfield type is enum, pahole ([1]) or llvm is forced to replace enum with int type. As a result, the original type information gets lost. Second, the original BTF design does not envision the possibility of BTF=>header_file conversion ([2]), hence does not encode "struct" or "union" info for a forward type. Such information is necessary to convert BTF to a header file. This patch set fixed the issue by introducing kind_flag, using one bit in type->info. When kind_flag, the struct/union btf_member->offset will encode both bitfield_size and bit_offset, covering both int and enum base types. The kind_flag is also used to indicate whether the forward type is a union (when set) or a struct. Patch #1 refactors function btf_int_bits_seq_show() so Patch #2 can reuse part of the function. Patch #2 implemented kind_flag support for struct/union/fwd types. Patch #3 added kind_flag support for cgroup local storage map pretty print. Patch #4 syncs kernel uapi btf.h to tools directory. Patch #5 added unit tests for kind_flag. Patch #6 added tests for kernel bpffs based pretty print with kind_flag. Patch #7 refactors function btf_dumper_int_bits() so Patch #8 can reuse part of the function. Patch #8 added bpftool support of pretty print with kind_flag set.

Added comments to help understand there is no overflow for total_bits_offset in bpftool function btf_dumper_int_bits(). . Added explanation of typedef type dumping fix in Patch #8 commit message. v1 -> v2: . If kind_flag is set for a structure, ensure an int member, whether it is a bitfield or not, is a regular int type. .

One is related to struct/union bitfield encoding and the other is related to forward type. Issue #1 and solution: ====================== Current btf encoding of bitfield follows what pahole generates. For each bitfield, pahole will duplicate the type chain and put the bitfield size at the final int or enum type. Since the BTF enum type cannot encode bit size, pahole workarounds the issue by generating an int type whenever the enum bit size is not 32. For example, -bash-4.4$ cat t.c typedef int ___int; enum A { A1, A2, A3 }; struct t { int a[5]; ___int b:4; volatile enum A c:4; } g; -bash-4.4$ gcc -c -O2 -g t.c The current kernel supports the following BTF encoding: $ pahole -JV t.o [1] TYPEDEF ___int type_id=2 [2] INT int size=4 bit_offset=0 nr_bits=32 encoding=SIGNED [3] ENUM A size=4 vlen=3 A1 val=0 A2 val=1 A3 val=2 [4] STRUCT t size=24 vlen=3 a type_id=5 bits_offset=0 b type_id=9 bits_offset=160 c type_id=11 bits_offset=164 [5] ARRAY (anon) type_id=2 index_type_id=2 nr_elems=5 [6] INT sizetype size=8 bit_offset=0 nr_bits=64 encoding=(none) [7] VOLATILE (anon) type_id=3 [8] INT int size=1 bit_offset=0 nr_bits=4 encoding=(none) [9] TYPEDEF ___int type_id=8 [10] INT (anon) size=1 bit_offset=0 nr_bits=4 encoding=SIGNED [11] VOLATILE (anon) type_id=10 Two issues are in the above: . by changing enum type to int, we lost the original type information and this will not be ideal later when we try to convert BTF to a header file. . the type duplication for bitfields will cause BTF bloat. Duplicated types cannot be deduplicated later if the bitfield size is different. To fix this issue, this patch implemented a compatible change for BTF struct type encoding: . the bit 31 of struct_type->info, previously reserved, now is used to indicate whether bitfield_size is encoded in btf_member or not. . if bit 31 of struct_type->info is set, btf_member->offset will encode like: bit 0 - 23: bit offset bit 24 - 31: bitfield size if bit 31 is not set, the old behavior is preserved: bit 0 - 31: bit offset So if the struct contains a bit field, the maximum bit offset will be reduced to (2^24 - 1) instead of MAX_UINT. The maximum bitfield size will be 256 which is enough for today as maximum bitfield in compiler can be 128 where int128 type is supported. This kernel patch intends to support the new BTF encoding: $ pahole -JV t.o [1] TYPEDEF ___int type_id=2 [2] INT int size=4 bit_offset=0 nr_bits=32 encoding=SIGNED [3] ENUM A size=4 vlen=3 A1 val=0 A2 val=1 A3 val=2 [4] STRUCT t kind_flag=1 size=24 vlen=3 a type_id=5 bitfield_size=0 bits_offset=0 b type_id=1 bitfield_size=4 bits_offset=160 c type_id=7 bitfield_size=4 bits_offset=164 [5] ARRAY (anon) type_id=2 index_type_id=2 nr_elems=5 [6] INT sizetype size=8 bit_offset=0 nr_bits=64 encoding=(none) [7] VOLATILE (anon) type_id=3 Issue #2 and solution: ====================== Current forward type in BTF does not specify whether the original type is struct or union. This will not work for type pretty print and BTF-to-header-file conversion as struct/union must be specified. $ cat tt.c struct t; union u; int foo(struct t *t, union u *u) { return 0; } $ gcc -c -g -O2 tt.c $ pahole -JV tt.o [1] INT int size=4 bit_offset=0 nr_bits=32 encoding=SIGNED [2] FWD t type_id=0 [3] PTR (anon) type_id=2 [4] FWD u type_id=0 [5] PTR (anon) type_id=4 To fix this issue, similar to issue #1, type->info bit 31 is used.

The simple fix is to exit the loop if it reached the bottom and ctx->table was not NULL. When iterating over the table's chains, the same problem as above existed. But worse than that, if a chain name was given the hash table wasn't used to find the corresponding chain. Fix this by introducing a helper function iterating over a chain's rules (and taking care of the cb->args handling), then introduce a shortcut to it if a chain name was given.

When such event occur, it is important to do this translation in both directions, dport translation on the receiving path and sport translation on the sending path. This commit fixes the sport translation when the peer requiring it is also the one that starts the media stream. In this scenario, first media stream packet is forwarded from LAN to WAN and will rely on nf_nat_sip_expected() to do the necessary sport translation. However, the expectation matched by this packet does not contain the necessary information for doing SNAT, this data being stored in the paired expectation created by the sender's SIP message (INVITE or reply to it).

Unfortunately it isn't that hard to trigger this situation on a busy system. In order to fix this problem, we should make sure hardware does whole transaction without waiting for software to fill some data. Fortunately, in addition to Manual mode that is currently used by the driver to perform I²C transfers, the module supports also so called Sequence mode. In this mode, the module automatically performs predefined sequence of operations - it sends a slave address, transmits specified number of bytes from the FIFO, changes transfer direction, resends the slave address and then reads specified number of bytes to FIFO. While very inflexible, this does fit a most common case of multi message transfer - the one where you first write a register number you want to read and then read it. To use this mode effectively, a number of conditions must be met to ensure the transaction does fit the predefined sequence. In case this is not the case, a fallback to manual mode is used. The initialization of this mode is very similar to Manual mode. The most notable difference is different bit in the Master Interrupt Status designating finishing of transaction. Also some of the errors, like TSS, cannot happen in this mode. While it is possible to support transactions requesting a read of any size (RFL interrupt will be generated when FIFO size is not enough) the TFL interrupt is not available in this mode, thus the write part of the transaction cannot exceed FIFO_SIZE (8). Note that in case of a NAK during transaction, the NA/ND status bits will be set before STOP command is generated, triggering an interrupt while the controller is still busy. Current solution for this problem is to actively wait for this command to stop before leaving xfer callback.

Moreover, most other BPF tracing types enabling bpf_probe_read()-like functionality have /not/ adapted this check, and in general these days it is well understood anyway that all the tracing programs are not stable with regards to future kernels as kernel internal data structures are subject to change from release to release. Back at last netconf we discussed [0] and agreed to remove this check from bpf_prog_load() and instead document it here in the uapi header that there is no such guarantee for stable API for these programs.

This means if a bio is plug-mergeable or bio-mergeable, it gets to bypass the blk-iolatency controller. The recent series [1], to tag all bios w/ blkgs undermined how iolatency was determining which bios it was charging and should process in rq_qos_done_bio(). Because all bios are being tagged, this caused the atomic_t for the struct rq_wait inflight count to underflow and result in a stall. This patch adds a new flag BIO_TRACKED to let controllers know that a bio is going through the rq_qos path. blk-iolatency now checks if this flag is set to see if it should process the bio in rq_qos_done_bio(). Overloading BLK_QUEUE_ENTERED works, but makes the flag rules confusing. BIO_THROTTLED was another candidate, but the flag is set for all bios that have gone through blk-throttle code. Overloading a flag comes with the burden of making sure that when either implementation changes, a change in setting rules for one doesn't cause a bug in the other.

So when dispach request from sw queue via blk_mq_flush_busy_ctxs() or blk_mq_dequeue_from_ctx(), one request belonging to other queue type of hctx can be dispatched to current hctx in case that read queue or poll queue is enabled. This patch fixes this issue by introducing per-queue-type list.

With this behavior, when no other request has been dispatched, rq_list in blk_mq_sched_dispatch_requests() is empty and blk_mq_sched_mark_restart_hctx() not called. This in turn leads to __blk_mq_free_request() call of blk_mq_sched_restart() to not run the queue when the already dispatched write request completes. The newly dispatched request stays stuck in the scheduler queue until eventually another request is submitted. This problem does not affect SCSI disk as the SCSI stack handles queue restart on request completion. However, this problem is can be triggered the nullblk driver with zoned mode enabled. Fix this by always requesting a queue restart in dd_dispatch_request() if no request was dispatched while WRITE requests are queued.

Passing the data between threads 1 and 2 is done by having 2 ordered events queues. One is always being stored by thread 1 while the other is flushed out in thread 2. Passing the data between threads 2 and 3 stays the same as was initially for threads 1 and 3. Signed-off-by: Jiri Olsa Acked-by: David S.

See [1] for background. [1]: https://lkml.org/lkml/2018/11/15/205 As Will indicated, the overflow handling would require single-stepping which is not supported at the moment.

For each event, it prints the count, the unit, the event name, the cgroup, and a bunch of other event specific fields (such as insn per cycles). When you use CSV-style mode, you expect a normalized output where each event is printed with the same number of fields regardless of what it is so it can easily be imported into a spreadsheet or parsed. For instance, if an event does not have a unit, then print an empty field for it. Although this approach was implemented for the unit, it was not for the cgroup. When mixing cgroup and non-cgroup events, then non-cgroup events would not show an empty field, instead the next field was printed, make columns not line up correctly. This patch fixes the cgroup output issues by forcing an empty field for non-cgroup events as soon as one event has cgroup.

Thus, perf_stat__update_shadow_stats() now saves scaled values of clock events in msecs, instead of original nsecs.

The logic uses KSFT_KHDR_INSTALL and top_srcdir as controls to initialize variables and include files to run headers_install from the top level Makefile. There are a few problems with this logic. 1. Exposes top_srcdir to all tests 2. Common logic impacts all tests 3. Uses KSFT_KHDR_INSTALL, top_srcdir, and khdr in an adhoc way. Tests add "khdr" dependency in their Makefiles to TEST_PROGS_EXTENDED in some cases, and STATIC_LIBS in other cases. This makes this framework confusing to use. The common logic that runs for all tests even when KSFT_KHDR_INSTALL isn't defined by the test. top_srcdir is initialized to a default value when test doesn't initialize it. It works for all tests without a sub-dir structure and tests with sub-dir structure fail to build. e.g: make -C sparc64/drivers/ or make -C drivers/dma-buf ../../lib.mk:20: ../../../../scripts/subarch.include: No such file or directory make: *** No rule to make target '../../../../scripts/subarch.include'. Stop. There is no reason to require all tests to define top_srcdir and there is no need to require tests to add khdr dependency using adhoc changes to TEST_* and other variables. Fix it with a consistent use of KSFT_KHDR_INSTALL and top_srcdir from tests that have the dependency on headers_install. Change common logic to include khdr target define and "all" target with dependency on khdr when KSFT_KHDR_INSTALL is defined. Only tests that have dependency on headers_install have to define just the KSFT_KHDR_INSTALL, and top_srcdir variables and there is no need to specify khdr dependency in the test Makefiles.

It makes sense to apply a) and b) independently: there are too many things going on behind free(), none of which depend on uart_port->lock.

When this busy time on the serial/tty subsystem happens during boot, where it is also busy on the userspace trying to initialise, some processes can continuously get preempted and will be on hold until the interrupts subside. The fix is to backoff on processing received characters for a specified amount of time when an input overrun is seen (received a new character before the previous one is processed). This only stops receive and will continue to transmit characters to serial port. After the backoff period is done, it receive will be re-enabled. This is optional and will only be enabled by setting 'overrun-throttle-ms' in the dts.

Note that the generic helper generic_remap_file_range_prep() does start and waits for writeback by calling filemap_write_and_wait_range(), however that is not enough for Btrfs for two reasons: 1) With compression, we need to start writeback twice in order to get the pages marked for writeback and ordered extents created; 2) filemap_write_and_wait_range() (and all its other variants) only waits for the IO to complete, but we need to wait for the ordered extents to finish, so that when we do the actual reflinking operations the file extent items are in the fs tree. This is also important due to the fact that the generic helper, for the deduplication case, compares the contents of the pages in the requested range, which might require reading extents from disk in the very unlikely case that pages get invalidated after writeback finishes (so the file extent items must be up to date in the fs tree). Since these reasons are specific to Btrfs we have to do it in the Btrfs code before calling generic_remap_file_range_prep(). This also results in a simpler way of dealing with existing delalloc in the source/target ranges, specially for the deduplication case where we used to lock all the pages first and then if we found any dealloc for the range, or ordered extent, we would unlock the pages trigger writeback and wait for ordered extents to complete, then lock all the pages again and check if deduplication can be done. So now we get a simpler approach: lock the inodes, then trigger writeback and then wait for ordered extents to complete. So make btrfs use generic_remap_file_range_prep() (XFS and OCFS2 use it) to eliminate duplicated code, fix a few bugs and benefit from future bug fixes done there - for example the recent clone and dedupe bugs involving reflinking a partial EOF block got a counterpart fix in the generic helper, since it affected all filesystems supporting these operations, so we no longer need special checks in Btrfs for them.

Additionally due to the structure of the code there is an additional check which deals with partial batches. Streamline all of this by explicitly using two loops. The outter one is used to process all pages while the inner one just fills in the batch of 16 (currently). Due to this new structure the code guarantees that all pages are processed in the loop hence the code to deal with any leftovers is eliminated.

This number seems rather small. And in fact when talking to the original authors their opinions were: "man that's a little bonkers" "i don't think we even need that code anymore" "I think it was there to make sure we had room for the blank 1M at the beginning. I bet it goes all the way back to v0" "we just don't need any of that tho, i say we just delete it" Clearly, this piece of code has lost its original intent throughout the years. It doesn't really bring any real practical benefits to the relocation process. Additionally, this patch makes the balance process more lightweight by removing a pair of shrink/grow operations which are rather expensive for heavily populated filesystems. This is mainly due to shrink requiring relocating block groups, involving heavy use of the btree. The intermediate shrink/grow can fail and leave the filesystem in a middle state that would need to be changed back by the user.

Fix this by performing a copy of the commit root's extent buffer when doing a search in the context of a send operation.

It will unlock the root node (and really every node) as it walks down the tree, only to re-lock it when it needs to do something. This is a problem because if we modify the tree we could cow a block in our path, which frees our reference to that block. Then once we get back to that shared block we'll free our reference to it again, and get ENOENT when trying to lookup our extent reference to that block in __btrfs_free_extent. This is ultimately happening because we have delayed items left to be processed for our deleted snapshot _after_ all of the inodes are closed for the snapshot. We only run the delayed inode item if we're deleting the inode, and even then we do not run the delayed insertions or delayed removals. These can be run at any point after our final inode does its last iput, which is what triggers the snapshot deletion. We can end up with the snapshot deletion happening and then have the delayed items run on that file system, resulting in the above problem. This problem has existed forever, however my patches made it much easier to hit as I wake up the cleaner much more often to deal with delayed iputs, which made us more likely to start the snapshot dropping work before the transaction commits, which is when the delayed items would generally be run. Before, generally speaking, we would run the delayed items, commit the transaction, and wakeup the cleaner thread to start deleting snapshots, which means we were less likely to hit this problem. You could still hit it if you had multiple snapshots to be deleted and ended up with lots of delayed items, but it was definitely harder. Fix for now by simply running all the delayed items before starting to drop the snapshot. We could make this smarter in the future by making the delayed items per-root, and then simply drop any delayed items for roots that we are going to delete. But for now just a quick and easy solution is the safest.

With the introduction of dealyed_refs_rsv infrastructure, namely btrfs_update_delayed_refs_rsv we now know exactly how much pending delayed refs space is required.

This works most of the time, except when it doesn't. We've had issues reported and seen in production where sometimes the global reserve is exhausted during transaction commit before we can run all of our delayed refs, resulting in an aborted transaction. Because of this voodoo we have equally dubious flushing semantics around throttling delayed refs which we often get wrong. So instead give them their own block_rsv. This way we can always know exactly how much outstanding space we need for delayed refs. This allows us to make sure we are constantly filling that reservation up with space, and allows us to put more precise pressure on the enospc system. Instead of doing math to see if its a good time to throttle, the normal enospc code will be invoked if we have a lot of delayed refs pending, and they will be run via the normal flushing mechanism. For now the delayed_refs_rsv will hold the reservations for the delayed refs, the block group updates, and deleting csums. We could have a separate rsv for the block group updates, but the csum deletion stuff is still handled via the delayed_refs so that will stay there. Historical background: The global reserve has grown to cover everything we don't reserve space explicitly for, and we've grown a lot of weird ad-hoc heuristics to know if we're running short on space and when it's time to force a commit. A failure rate of 20-40 file systems when we run hundreds of thousands of them isn't super high, but cleaning up this code will make things less ugly and more predictible. Thus the delayed refs rsv. We always know how many delayed refs we have outstanding, and although running them generates more we can use the global reserve for that spill over, which fits better into it's desired use than a full blown reservation. This first approach is to simply take how many times we're reserving space for and multiply that by 2 in order to save enough space for the delayed refs that could be generated. This is a niave approach and will probably evolve, but for now it works.

The reason this case is valid is due to find_lock_delalloc_range returning any available range after the passed delalloc_start and ignoring whether the page under writeback is within that range. In turn ordered extents (OE) are always created for the returned range from find_lock_delalloc_range. If, however, a failure occurs while OE are being created then the clean up code in btrfs_cleanup_ordered_extents will be called. Unfortunately the code in btrfs_cleanup_ordered_extents doesn't consider the case of such 'foreign' range being processed and instead it always assumes that the range OE are created for belongs to the page. This leads to the first page of such foregin range to not be cleaned up since it's deliberately missed and skipped by the current cleaning up code. Fix this by correctly checking whether the current page belongs to the range being instantiated and if so adjsut the range parameters passed for cleaning up. If it doesn't, then just clean the whole OE range directly.

We follow the ancestors using the VFS' dget_parent() API. This means that if we create a new link for a file in a directory that is new (or in an any other new ancestor directory) and then fsync the file using an old hard link, we end up not logging the new ancestor, and on log replay that new hard link and ancestor do not exist. In some cases, involving renames, the file will not exist at all. Example: mkfs.btrfs -f /dev/sdb mount /dev/sdb /mnt mkdir /mnt/A touch /mnt/foo ln /mnt/foo /mnt/A/bar xfs_io -c fsync /mnt/foo In this example after log replay only the hard link named 'foo' exists and directory A does not exist, which is unexpected. In other major linux filesystems, such as ext4, xfs and f2fs for example, both hard links exist and so does directory A after mounting again the filesystem. Checking if any new ancestors are new and need to be logged was added in 2009 by commit 12fcfd22fe5b ("Btrfs: tree logging unlink/rename fixes"), however only for the ancestors of the hard link (dentry) for which the fsync was issued, instead of checking for all ancestors for all of the inode's hard links. So fix this by tracking the id of the last transaction where a hard link was created for an inode and then on fsync fallback to a full transaction commit when an inode has more than one hard link and at least one new hard link was created in the current transaction. This is the simplest solution since this is not a common use case (adding frequently hard links for which there's an ancestor created in the current transaction and then fsync the file). In case it ever becomes a common use case, a solution that consists of iterating the fs/subvol btree for each hard link and check if any ancestor is new, could be implemented. This solves many unexpected scenarios reported by Jayashree Mohan and Vijay Chidambaram, and for which there is a new test case for fstests under review.

So while the transaction is blocked waiting for scrub to pause, we can not do memory allocation with GFP_KERNEL from scrub, otherwise we risk getting into a deadlock with reclaim. Checking for scrub pause requests is done early at the beginning of the while loop of scrub_stripe() and later in the loop, scrub_extent() and scrub_raid56_parity() are called, which in turn call scrub_pages() and scrub_pages_for_parity() respectively. These last two functions do memory allocations using GFP_KERNEL. Same problem could happen while scrubbing the super blocks, since it calls scrub_pages(). We also can not have any of the worker tasks, created by the scrub task, doing GFP_KERNEL allocations, because before pausing, the scrub task waits for all the worker tasks to complete (also done at scrub_stripe()). So make sure GFP_NOFS is used for the memory allocations because at any time a scrub pause request can happen from another task that started to commit a transaction.

If this is the case the actual retrying is handled by bio_readpage_error. Alternatively, if this bio belongs to the btree inode then btree_io_failed_hook just does some cleanup and doesn't retry anything. This patch simplifies the code flow by eliminating readpage_io_failed_hook and instead open-coding btree_io_failed_hook in end_bio_extent_readpage. Also eliminate some needless checks since IO is always performed on either data inode or btree inode, both of which are guaranteed to have their extent_io_tree::ops set.

The following time diagrams show how both cases happen. First scenario: CPU 0 CPU 1 btrfs_ioctl() btrfs_ioctl_quota_ctl() btrfs_quota_enable() mutex_lock(fs_info->qgroup_ioctl_lock) btrfs_start_transaction() btrfs_ioctl() btrfs_ioctl_snap_create_v2 create_snapshot() --> adds snapshot to the list pending_snapshots of the current transaction btrfs_commit_transaction() create_pending_snapshots() create_pending_snapshot() qgroup_account_snapshot() btrfs_qgroup_inherit() mutex_lock(fs_info->qgroup_ioctl_lock) --> deadlock, mutex already locked by this task at btrfs_quota_enable() Second scenario: CPU 0 CPU 1 btrfs_ioctl() btrfs_ioctl_quota_ctl() btrfs_quota_enable() mutex_lock(fs_info->qgroup_ioctl_lock) btrfs_start_transaction() btrfs_ioctl() btrfs_ioctl_snap_create_v2 create_snapshot() --> adds snapshot to the list pending_snapshots of the current transaction btrfs_commit_transaction() --> waits for task at CPU 0 to release its transaction handle btrfs_commit_transaction() --> sees another task started the transaction commit first --> releases its transaction handle --> waits for the transaction commit to be completed by the task at CPU 1 create_pending_snapshot() qgroup_account_snapshot() btrfs_qgroup_inherit() mutex_lock(fs_info->qgroup_ioctl_lock) --> deadlock, task at CPU 0 has the mutex locked but it is waiting for us to finish the transaction commit So fix this by setting the quota enabled flag in fs_info after committing the transaction at btrfs_quota_enable(). This ends up serializing quota enable and snapshot creation as if the snapshot creation happened just before the quota enable request. The quota rescan task, scheduled after committing the transaction in btrfs_quote_enable(), will do the accounting.

This is wrong because a retry might be needed, so our actions must not have side effects and must be repeatable as long as read_seqretry() returns a non-zero value. In other words, we were essentially ignoring the sequence lock; 2) Right below the read sequence lock loop, we were reading the values from avail_metadata_alloc_bits and avail_data_alloc_bits without any protection from concurrent writers, that is, reading them outside of the read sequence lock critical section. So fix this by making sure we only read the available allocation bits while in a read sequence lock critical section and that what we do in the critical section is repeatable (has nothing that can not be undone) so that any eventual retry that is needed is handled properly.

When finishing a transaction commit we find each range, process it (discard the extents, unpin them) and then remove it from the red black tree. We can use an extent state record as a cache when searching for a range, so that when we clean the range we can use the cached extent state we passed to the search function instead of iterating the red black tree again. Doing things as fast as possible when finishing a transaction (in state TRANS_STATE_UNBLOCKED) is convenient as it reduces the time we block another task that wants to commit the next transaction. So change clear_extent_dirty() to allow an optional extent state record to be passed as an argument, which will be passed down to __clear_extent_bit.

Namely, this is the case where a multidisk filesystem has already undergone at least one successful fsid change i.e all disks have the METADATA_UUID incompat bit and power failure occurs as another fsid change is in progress. When such an event occurs, disks could be split in 2 groups. One of the groups will have both METADATA_UUID and CHANGING_FSID_V2 flags set coupled with old fsid/metadata_uuid pairs. The other group of disks will have only METADATA_UUID bit set and their fsid will be different than the one in disks in the first group. Here we look at the following cases: a) A disk from the first group is scanned first, so fs_devices is created with stale fsid/metdata_uuid. Then when a disk from the second group is scanned it needs to first check whether there exists such an fs_devices that has fsid_change set to true (because it was created with a disk having the CHANGING_FSID_V2 flag), the metadata_uuid and fsid of the fs_devices will be different (since it was created by a disk which already has had at least 1 successful fsid change) and finally the metadata_uuid of the fs_devices will equal that of the currently scanned disk (because metadata_uuid never really changes). When the correct fs_devices is found the information from the scanned disk will replace the current one in fs_devices since the scanned disk will have higher generation number. b) A disk from the second group is scanned so fs_devices is created as usual with differing fsid/metdata_uid. Then when a disk from the first group is scanned the code detects that it has both CHANGING_FSID_V2 and METADATA_UUID flags set and will search for fs_devices that has differing metadata_uuid/fsid and whose metadata_uuid is the same as that of the scanned device.

Namely handle the situation that can occur when some of the disks in multi-disk fs have completed their fsid change i.e they have METADATA_UUID incompat flag set, have cleared the CHANGING_FSID_V2 flag and their fsid/metadata_uuid are different. At the same time the other half of the disks will have their fsid/metadata_uuid unchanged and will only have CHANGING_FSID_V2 flag. This is handled by introducing code in the scan path which: a) Handles the case when a device with CHANGING_FSID_V2 flag is scanned and as a result btrfs_fs_devices is created with matching fsid/metdata_uuid. Subsequently, when a device with completed fsid change is scanned it will detect this via the new code in find_fsid i.e that such an fs_devices exist that fsid_change flag is set to true, it's metadata_uuid/fsid match and the metadata_uuid of the scanned device matches that of the fs_devices. In this case, it's important to note that the devices which has its fsid change completed will have a higher generation number than the device with FSID_CHANGING_V2 flag set, so its superblock block will be used during mount. To prevent an assertion triggering because the sb used for mounting will have differing fsid/metadata_uuid than the ones in the fs_devices struct also add code in device_list_add which overwrites the values in fs_devices. b) Alternatively we can end up with a device that completed its fsid change be scanned first which will create the respective btrfs_fs_devices struct with differing fsid/metadata_uuid. In this case when a device with FSID_CHANGING_V2 flag set is scanned it will call the newly added find_fsid_inprogress function which will return the correct fs_devices.

The highest generation number among all devices registered to a particular btrfs_fs_devices 2. A boolean flag whether a given btrfs_fs_devices was created by a device which had the FSID_CHANGING_V2 flag set. This is a preparatory patch and just introduces the variables as well as code which sets them, their actual use is going to happen in a later patch.

This patch handles the case where power failure occurs while the first transaction (the one setting CHANGING_FSID_V2) flag is being persisted on disk. This can cause the btrfs_fs_devices of this filesystem to be created by a device which: a) has the CHANGING_FSID_V2 flag set but its fsid value is intact b) or a device which doesn't have CHANGING_FSID_V2 flag set and its fsid value is intact This situation is trivially handled by the current find_fsid code since in both cases the devices are going to be treated like ordinary devices. Since btrfs is always mounted using the superblock of the latest device (the one with highest generation number), meaning it will have the CHANGING_FSID_V2 flag set, ensure it's being cleared on mount. On the first transaction commit following mount all disks will have it cleared.

This field adds another level of indirection such that when the FSID is changed what really happens is the current UUID (the one with which the fs was created) is copied to the 'metadata_uuid' field in the superblock as well as a new incompat flag is set METADATA_UUID. When the kernel detects this flag is set it knows that the superblock in fact has 2 UUIDs: 1. Is the UUID which is user-visible, currently known as FSID. 2. Metadata UUID - this is the UUID which is stamped into all on-disk datastructures belonging to this file system. When the new incompat flag is present device scanning checks whether both fsid/metadata_uuid of the scanned device match any of the registered filesystems. When the flag is not set then both UUIDs are equal and only the FSID is retained on disk, metadata_uuid is set only in-memory during mount. Additionally a new metadata_uuid field is also added to the fs_info struct. It's initialised either with the FSID in case METADATA_UUID incompat flag is not set or with the metdata_uuid of the superblock otherwise. This commit introduces the new fields as well as the new incompat flag and switches all users of the fsid to the new logic.

We have a known bug in btrfs, that we let the device path be changed after the device has been mounted.

For example: Initially.. /dev/mmcblk0p4 is mounted as / $ lsblk NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT mmcblk0 179:0 0 29.2G 0 disk |-mmcblk0p4 179:4 0 4G 0 part / |-mmcblk0p2 179:2 0 500M 0 part /boot |-mmcblk0p3 179:3 0 256M 0 part [SWAP] `-mmcblk0p1 179:1 0 256M 0 part /boot/efi $ btrfs fi show Label: none uuid: 07892354-ddaa-4443-90ea-f76a06accaba Total devices 1 FS bytes used 1.40GiB devid 1 size 4.00GiB used 3.00GiB path /dev/mmcblk0p4 Copy mmcblk0 to sda $ dd if=/dev/mmcblk0 of=/dev/sda And immediately after the copy completes the change in the device superblock is notified which the automount scans using btrfs device scan and the new device sda becomes the mounted root device. $ lsblk NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT sda 8:0 1 14.9G 0 disk |-sda4 8:4 1 4G 0 part / |-sda2 8:2 1 500M 0 part |-sda3 8:3 1 256M 0 part `-sda1 8:1 1 256M 0 part mmcblk0 179:0 0 29.2G 0 disk |-mmcblk0p4 179:4 0 4G 0 part |-mmcblk0p2 179:2 0 500M 0 part /boot |-mmcblk0p3 179:3 0 256M 0 part [SWAP] `-mmcblk0p1 179:1 0 256M 0 part /boot/efi $ btrfs fi show / Label: none uuid: 07892354-ddaa-4443-90ea-f76a06accaba Total devices 1 FS bytes used 1.40GiB devid 1 size 4.00GiB used 3.00GiB path /dev/sda4 The bug is quite nasty that you can't either unmount /dev/sda4 or /dev/mmcblk0p4.

However, the same calculation reappears a bit later, and that one was not changed yet. The resulting bug that is exposed is that the newly allocated device extents ('stripes') can have a few MiB overlap with the next thing stored after them, which is another device extent or the end of the disk. The scenario in which this can happen is: * The block device for the filesystem is less than 10GiB in size. * The amount of contiguous free unallocated disk space chosen to use for chunk allocation is 20% of the total device size, or a few MiB more or less. An example: - The filesystem device is 7880MiB (max_chunk_size gets set to 788MiB) - There's 1578MiB unallocated raw disk space left in one contiguous piece. In this case stripe_size is first calculated as 789MiB, (half of 1578MiB). Since 789MiB (stripe_size * data_stripes) > 788MiB (max_chunk_size), we enter the if block. Now stripe_size value is immediately overwritten while calculating an adjusted value based on max_chunk_size, which ends up as 788MiB. Next, the value is rounded up to a 16MiB boundary, 800MiB, which is actually more than the value we had before. However, the last comparison fails to detect this, because it's comparing the value with the total amount of free space, which is about twice the size of stripe_size. In the example above, this means that the resulting raw disk space being allocated is 1600MiB, while only a gap of 1578MiB has been found. The second device extent object for this DUP chunk will overlap for 22MiB with whatever comes next. The underlying problem here is that the stripe_size is reused all the time for different things. So, when entering the code in the if block, stripe_size is immediately overwritten with something else. If later we decide we want to have the previous value back, then the logic to compute it was copy pasted in again. With this change, the value in stripe_size is not unnecessarily destroyed, so the duplicated calculation is not needed any more.

But if there are writers steadily creating dirty pages in our subvolume, the snapshot may take a very long time to complete. To fix the problem, we use tagged writepage for snapshot flusher as we do in the generic write_cache_pages(), so we can omit pages dirtied after the snapshot command. This does not change the semantics regarding which data get to the snapshot, if there are pages being dirtied during the snapshotting operation. There's a sync called before snapshot is taken in old/new case, any IO in flight just after that may be in the snapshot but this depends on other system effects that might still sync the IO. We do a simple snapshot speed test on a Intel D-1531 box: fio --ioengine=libaio --iodepth=32 --bs=4k --rw=write --size=64G --direct=0 --thread=1 --numjobs=1 --time_based --runtime=120 --filename=/mnt/sub/testfile --name=job1 --group_reporting & sleep 5; time btrfs sub snap -r /mnt/sub /mnt/snap; killall fio original: 1m58sec patched: 6.54sec This is the best case for this patch since for a sequential write case, we omit nearly all pages dirtied after the snapshot command. For a multi writers, random write test: fio --ioengine=libaio --iodepth=32 --bs=4k --rw=randwrite --size=64G --direct=0 --thread=1 --numjobs=4 --time_based --runtime=120 --filename=/mnt/sub/testfile --name=job1 --group_reporting & sleep 5; time btrfs sub snap -r /mnt/sub /mnt/snap; killall fio original: 15.83sec patched: 10.35sec The improvement is smaller compared to the sequential write case, since we omit only half of the pages dirtied after snapshot command.

Additionally btrfs_schedule_bios does the duplicate device->bdev check which has already been performed in btrfs_map_bio. This patch moves the DEV_STATE_MISSING check in btrfs_map_bio and removes the duplicate device->bdev check. Doing so ensures that no bio cloning/submission happens for both async/sync requests in the face of missing device.

We free the log trees when we are in the critical section of a transaction commit (the transaction state is set to TRANS_STATE_COMMIT_DOING), so it's of great convenience to do everything as fast as possible in order to reduce the time we block other tasks from starting a new transaction.

Then this buffer is locked for reading and its ref count is incremented by 1. Finally it's fed to the passed iterate_irefs_t function. The actual iterate call back is inode_to_path (coming from paths_from_inode) which feeds the eb to btrfs_ref_to_path. In this final function the passed eb is only read by first assigning it to the local eb variable. This variable is only modified in the case another eb was referenced from the passed path that is eb != eb_in check triggers. Considering this there is no point in locking the cloned eb in iterate_inode_refs since it's never being modified and is not published anywhere. Furthermore the cloned eb is completely fine having its ref count be 1.

However, now that the proper restrictions are in place, Btrfs can support swap files through the swap file a_ops, similar to iomap in commit 67482129cdab ("iomap: add a swapfile activation function"). For Btrfs, activation needs to make sure that the file can be used as a swap file, which currently means that it must be fully allocated as NOCOW with no compression on one device. It must also do the proper tracking so that ioctls will not interfere with the swap file. Deactivation clears this tracking.

When a swap file is active, we must make sure that the extents of the file are not moved and that they don't become shared. That means that the following are not safe: - chattr +c (enable compression) - reflink - dedupe - snapshot - defrag Don't allow those to happen on an active swap file. Additionally, balance, resize, device remove, and device replace are also unsafe if they affect an active swapfile. Add a red-black tree of block groups and devices which contain an active swapfile. Relocation checks each block group against this tree and skips it or errors out for balance or resize, respectively. Device remove and device replace check the tree for the device they will operate on. Note that we don't have to worry about chattr -C (disable nocow), which we ignore for non-empty files, because an active swapfile must be non-empty and can't be truncated. We also don't have to worry about autodefrag because it's only done on COW files. Truncate and fallocate are already taken care of by the generic code. Device add doesn't do relocation so it's not an issue, either.

Analysis from Hans: "Imagine allocating a DATA|DUP chunk. In the chunk allocator, we first set... max_stripe_size = SZ_1G; max_chunk_size = BTRFS_MAX_DATA_CHUNK_SIZE ... which is 10GiB. Then... /* we don't want a chunk larger than 10% of writeable space */ max_chunk_size = min(div_factor(fs_devices->total_rw_bytes, 1), max_chunk_size); Imagine we only have one 7880MiB block device in this filesystem. Now max_chunk_size is down to 788MiB. The next step in the code is to search for max_stripe_size * dev_stripes amount of free space on the device, which is in our example 1GiB * 2 = 2GiB. Imagine the device has exactly 1578MiB free in one contiguous piece. This amount of bytes will be put in devices_info[ndevs - 1].max_avail Next we recalculate the stripe_size (which is actually the device extent length), based on the actual maximum amount of available raw disk space: stripe_size = div_u64(devices_info[ndevs - 1].max_avail, dev_stripes); stripe_size is now 789MiB Next we do... data_stripes = num_stripes / ncopies ...where data_stripes ends up as 1, because num_stripes is 2 (the amount of device extents we're going to have), and DUP has ncopies 2. Next there's a check... if (stripe_size * data_stripes > max_chunk_size) ...which matches because 789MiB * 1 > 788MiB. We go into the if code, and next is... stripe_size = div_u64(max_chunk_size, data_stripes); ...which resets stripe_size to max_chunk_size: 788MiB Next is a fun one... /* bump the answer up to a 16MB boundary */ stripe_size = round_up(stripe_size, SZ_16M); ...which changes stripe_size from 788MiB to 800MiB. We're not done changing stripe_size yet... /* But don't go higher than the limits we found while searching * for free extents */ stripe_size = min(devices_info[ndevs - 1].max_avail, stripe_size); This is bad. max_avail is twice the stripe_size (we need to fit 2 device extents on the same device for DUP). The result here is that 800MiB < 1578MiB, so it's unchanged. However, the resulting DUP chunk will need 1600MiB disk space, which isn't there, and the second dev_extent might extend into the next thing (next dev_extent? end of device?) for 22MiB. The last shown line of code relies on a situation where there's twice the value of stripe_size present as value for the variable stripe_size when it's DUP. This was actually the case before commit 92e222df7b "btrfs: alloc_chunk: fix DUP stripe size handling", from which I quote: "[...] in the meantime there's a check to see if the stripe_size does not exceed max_chunk_size. Since during this check stripe_size is twice the amount as intended, the check will reduce the stripe_size to max_chunk_size if the actual correct to be used stripe_size is more than half the amount of max_chunk_size." In the previous version of the code, the 16MiB alignment (why is this done, by the way?) would result in a 50% chance that it would actually do an 8MiB alignment for the individual dev_extents, since it was operating on double the size. Does this matter? Does it matter that stripe_size can be set to anything which is not 16MiB aligned because of the amount of remaining available disk space which is just taken? What is the main purpose of this round_up? The most straightforward thing to do seems something like... stripe_size = min( div_u64(devices_info[ndevs - 1].max_avail, dev_stripes), stripe_size ) ..just putting half of the max_avail into stripe_size."

This will fix an issue that we have with the Intel USB role switch driver on systems that don't have USB Type-C connectors: Intel USB role switch driver depends on the USB role switch class as it should, but since there was no way for the user to enable the USB role switch class, there was also no way to select that driver. USB Type-C drivers select the USB role switch class which makes the Intel USB role switch driver available and therefore hides the problem.

The application doesn't know how big the response it beforehand so it always needs to maintain a 4K buffer and read the max (4K). In case if the user of the TSS library doesn't provide big enough buffer the TCTI spec says that the library should set the required size and return TSS2_TCTI_RC_INSUFFICIENT_BUFFER error code so that the application could allocate a bigger buffer and call receive again. To make it possible in the TSS library, this requires being able to do partial reads from the driver. The library would read the 10 bytes header first to get the actual size of the response from the header, and then read the rest of the response. This patch adds support for partial reads, i.e. the user can read the response in one or multiple reads, until the whole response is consumed. The user can also read only part of the response and ignore the rest by issuing a new write to send a new command.

The current code is a bit messy and primarily that's because it prepares to support running BKOPS in an asynchronous mode. However, that mode has never been fully implemented/enabled. Instead BKOPS is always executed in synchronously, when the card has reported an urgent BKOPS level. For these reasons, let's make the code more readable by dropping the unused parts. Let's also rename mmc_start_bkops() to mmc_run_bkops(), as to make it more descriptive.

A small failure band may be present in the tuning range which may be missed by the current algorithm. Furthermore, the failure bands vary with temperature leading to different optimum tuning values for different temperatures. As suggested in the related Application Report (SPRACA9B - October 2017 - Revised July 2018 [2]), tuning should be done in two stages. In stage 1, assign the optimum ratio in the maximum pass window for the current temperature. In stage 2, if the chosen value is close to the small failure band, move away from it in the appropriate direction.

Hence it's necessary to add runtime PM support for the memstick host. To keep memstick host stays suspended when it's not in use, convert the card detection function from kthread to delayed_work, which can be scheduled when the host is resumed and can be canceled when the host is suspended. Put the device to suspend when there's no card and the power mode is MEMSTICK_POWER_OFF.

Although, the logic can't detect when a card is removed. This makes things a bit tricky, which is why the current method is simply to turn on MMC_CAP_NEEDS_POLL during probe. Using MMC_CAP_NEEDS_POLL means lots of energy being wasted, as the mmc host becomes runtime resumed frequently by the mmc core, while it polls for new cards being inserted. To address this problem, let's start relying on that the rtsx USB driver runtime resumes its child device, which is the rtsx_usb_sdmmc device, when it detects that a new card being inserted. This means dropping MMC_CAP_NEEDS_POLL from being set during probe. Instead let's implement a ->runtime_resume() callback to schedule a detect work and to set MMC_CAP_NEEDS_POLL. In this way, polling is enabled as long as there is card inserted, thus we can rely on the mmc core to detect also when the card becomes removed. Furthermore, to avoid polling forever after a card has been removed, let's implement a ->runtime_suspend() callback and make it clear MMC_CAP_NEEDS_POLL.

This really doesn't makes sense, as it's a USB driven host device, which needs it rtsx USB device (parent device) to be runtime resumed to provide power to the card. In practise, using the autosuspend or any async runtime PM suspend method, means unnecessary delaying the host device and thus the parent, to be runtime suspended when a card is removed/powered off. For this reasons, let's simply drop the support for runtime PM autosuspend and tell the mmc core to use synced runtime PM suspend methods, via setting MMC_CAP_SYNC_RUNTIME_PM during probe. Moreover, as the mmc core nowadays deploys runtime PM reference counting of the mmc host device, convert ->set_ios() to use the more lightweight pm_runtime_get_noresume() and pm_runtime_put_noidle() APIs.

[ 16.461094] jz4740-mmc 13450000.mmc: [jz4740_mmc_prepare_dma_data] invalid cookie: data->host_cookie 567 host->next_data.cookie 568 [ 16.473120] jz4740-mmc 13450000.mmc: [jz4740_mmc_prepare_dma_data] invalid cookie: data->host_cookie 568 host->next_data.cookie 569 [ 16.485144] jz4740-mmc 13450000.mmc: [jz4740_mmc_prepare_dma_data] invalid cookie: data->host_cookie 569 host->next_data.cookie 570 [ 16.497170] jz4740-mmc 13450000.mmc: [jz4740_mmc_prepare_dma_data] invalid cookie: data->host_cookie 570 host->next_data.cookie 571 The problem seems to be related to how pre_req/post_req is implemented. Currently, it seems the driver expects jz4740_mmc_prepare_dma_data() to be called with monotonically increasing host_cookie values, which is wrong. Moreover, the implementation is overly complicated, keeping track of unneeded "next cookie" state. So, instead of attempting to fix the current pre_req/post_req implementation, this commit refactors the driver, dropping the state, following other drivers such as dw_mmc and sdhci.

The existing kvmppc_hv_emulate_mmio function can be used here. The main challenge is that for a load the result must be stored into the L2 gpr, not an L1 gpr as would normally be the case after going out to qemu to complete the operation. This presents a challenge as at this point the L2 gpr state has been written back into L1 memory. To work around this we store the address in L1 memory of the L2 gpr where the result of the load is to be stored and use the new io_gpr value KVM_MMIO_REG_NESTED_GPR to indicate that this is a nested load for which completion must be done when returning back into the kernel. Then in kvmppc_complete_mmio_load() the resultant value is written into L1 memory at the location of the indicated L2 gpr. Note that we don't currently let an L1 guest emulate a device for an L2 guest which is then passed through to an L3 guest.

They do so by translating through the process table to obtain a guest real address and then using kvm_read_guest or kvm_write_guest to make the access with the guest real address. This method of access however only works for L1 guests and will give the incorrect results for a nested guest. We can however use the store_to_eaddr and load_from_eaddr kvmppc_ops to perform the access for a nested guesti (and a L1 guest). So attempt this method first and fall back to the old method if this fails and we aren't running a nested guest. At this stage there is no fall back method to perform the access for a nested guest and this is left as a future improvement. For now we will return to the nested guest and rely on the fact that a translation should be faulted in before retrying the access.

The quadrant number is the two high bits of the effective address and determines the fully qualified address to be used for the translation. The fully qualified address consists of the effective lpid, the effective pid and the effective address. This gives then 4 possible quadrants 0, 1, 2, and 3. When accessing these quadrants the fully qualified address is obtained as follows: Quadrant | Hypervisor | Guest -------------------------------------------------------------------------- | EA[0:1] = 0b00 | EA[0:1] = 0b00 0 | effLPID = 0 | effLPID = LPIDR | effPID = PIDR | effPID = PIDR -------------------------------------------------------------------------- | EA[0:1] = 0b01 | 1 | effLPID = LPIDR | Invalid Access | effPID = PIDR | -------------------------------------------------------------------------- | EA[0:1] = 0b10 | 2 | effLPID = LPIDR | Invalid Access | effPID = 0 | -------------------------------------------------------------------------- | EA[0:1] = 0b11 | EA[0:1] = 0b11 3 | effLPID = 0 | effLPID = LPIDR | effPID = 0 | effPID = 0 -------------------------------------------------------------------------- In the Guest; Quadrant 3 is normally used to address the operating system since this uses effPID=0 and effLPID=LPIDR, meaning the PID register doesn't need to be switched. Quadrant 0 is normally used to address user space since the effLPID and effPID are taken from the corresponding registers. In the Host; Quadrant 0 and 3 are used as above, however the effLPID is always 0 to address the host. Quadrants 1 and 2 can be used by the host to address guest memory using a guest effective address. Since the effLPID comes from the LPID register, the host loads the LPID of the guest it would like to access (and the PID of the process) and can perform accesses to a guest effective address. This means quadrant 1 can be used to address the guest user space and quadrant 2 can be used to address the guest operating system from the hypervisor, using a guest effective address. Access to the quadrants can cause a Hypervisor Data Storage Interrupt (HDSI) due to being unable to perform partition scoped translation. Previously this could only be generated from a guest and so the code path expects us to take the KVM trampoline in the interrupt handler. This is no longer the case so we modify the handler to call bad_page_fault() to check if we were expecting this fault so we can handle it gracefully and just return with an error code. In the hash mmu case we still raise an unknown exception since quadrants aren't defined for the hash mmu.

Only the guest real addresses covered by the memslot are flushed. The reason for this is to get rid of any 2M PTEs in the partition-scoped page tables that correspond to host transparent huge pages, so that page dirtiness is tracked at a system page (4k or 64k) granularity rather than a 2M granularity. The page tables are also flushed when turning dirty tracking off so that the memslot's address space can be repopulated with THPs if possible. To do this, we add a new function kvmppc_radix_flush_memslot(). Since this does what's needed for kvmppc_core_flush_memslot_hv() on a radix guest, we now make kvmppc_core_flush_memslot_hv() call the new kvmppc_radix_flush_memslot() rather than calling kvm_unmap_radix() for each page in the memslot. This has the effect of fixing a bug in that kvmppc_core_flush_memslot_hv() was previously calling kvm_unmap_radix() without holding the kvm->mmu_lock spinlock, which is required to be held.

Miller Date: Sun Dec 16 15:20:35 2018 -0800 Merge branch 'mlxsw-spectrum_acl-Add-Bloom-filter-support' Ido Schimmel says: ==================== mlxsw: spectrum_acl: Add Bloom filter support Nir says: Spectrum-2 uses Bloom filter to reduce the number of lookups in the algorithmic TCAM (A-TCAM). HW performs multiple exact match lookups in a given region using a key composed of { packet & mask, mask ID, region ID }. The masks which are used in a region are called rule patterns or RP. When such multiple masks are used, the A-TCAM region uses an eRP (extended RP) table that describes which rule patterns are in use and defines the order of the lookup. When eRP table is used in a region, one way to reduce the number of the lookups is to consult a Bloom filter before doing the lookup. A Bloom filter is a space-efficient probabilistic data structure, on which a query returns either "possibly in set" or "definitely not in set". HW can skip a lookup if a query on the Bloom filter results a "definitely not set" response. The mlxsw driver implements a "counting filter" and when either a new entry is marked or the last entry is removed it will update the HW. Update of this counting filter occurs when rule is configured or deleted from a region. Patch #1 adds PEABFE register which is used for setting Bloom filter entries. Patch #2 adds Bloom filter resources. Patch #3 and patch #4 provide Bloom filter handling within mlxsw, by adding initialization and logic for updating the Bloom bit vector in HW. Patch #5 and patch #6 add required calls for Bloom filter update as part of rule configuration flow. Patch #7 handles transitions to and from eRP table. It uses a list to keep A-TCAM rules in order to update rules in Bloom filter, in cases of transitions from master mask based A-TCAM region to an eRP table based region and vice versa. Patch #8 removes a trick done on master RP index to a remaining RP, since Bloom filter is updated on eRP transitions. Finally, patch #9 activates Bloom filter mechanism in HW, by cancelling the bypass that was configured before and the remaining three patches are selftests that exercise the new code. ==================== Signed-off-by: David S.

In order to do so also add crc-16 computation based on the specific Spectrum-2 polynomial and a function for encoding the crc-16 input in the manner dictated by HW implementation.

So this patch adds the PM runtime support in order to gain more power control than system suspend and resume use case. For PM runtime, there are a few related changes happening: 1) Added a new pm_dev device pointer for all the PM runtime callbacks. This is because hwmon core registers a child device for each hwmon driver and passes it back to each driver. So there might be a mismatch between two device pointers in the driver if mixing using them. 2) Added a check in ina3221_is_enabled() to make sure that the chip is resumed. 3) Bypassed the unchanged status in ina3221_write_enable() in order to keep the PM runtime refcount being matched. 4) Removed the reset routine in the probe() by calling the resume() via pm_runtime_get_sync() instead, as they're similar. It's also necessary to do so to match initial PM refcount with the number of enabled channels.

The CVRF bit is to indicate that data conversion is finished, so polling the CVRF bit before data reading could ensure the result being valid. An alternative way could be to wait for expected time between the channel enabling and the data reading. And this could avoid extra I2C communications. However, INA3221 seemly takes longer time than what's stated in the datasheet. Test results show that sometimes it couldn't finish data conversion in time. So this patch plays safe by adding a CVRF polling to make sure the data register is updated with the new data.

This is required when polling CVRF bit of the MASK/ENABLE register because this bit is cleared on a read of this MASK/ENABLE register or a write to CONFIG register, which means that this bit might be accidentally cleared by reading other fields like alert flags. So this patch adds a mutex lock to protect the write() and read() callbacks. The read_string() callback won't need the lock since it just returns the label without touching any hardware register.

But reading the MASK_ENABLE register would clear the CVRF bit according to the datasheet. So it'd be safer to fence for disabled channels in order to add pm runtime feature.

The OCC can provide the raw sensor data as well as perform thermal and power management on the system. This driver provides a hwmon interface to the OCC from a service processor (e.g. a BMC). The driver supports both POWER8 and POWER9 OCCs. Communications with the POWER8 OCC are established over standard I2C bus. The driver communicates with the POWER9 OCC through the FSI-based OCC driver, which handles the lower-level communication details. This patch lays out the structure of the OCC hwmon driver. There are two platform drivers, one each for P8 and P9 OCCs. These are probed through the I2C tree and the FSI-based OCC driver, respectively. The patch also defines the first common structures and methods between the two OCC versions.

This caused segfaults in DCCP lookups because DCCP did not initialize the (addr,port) hashtable. This patch adds said initialization. The only non-trivial issue here is the size of the new hashtable. It seemed reasonable to make it match the size of the port-only hashtable (= INET_LHTABLE_SIZE) that was used previously. Other parameters to inet_hashinfo2_init() match those used in TCP. Tested: syzcaller issues fixed; the second patch in the patchset tests that DCCP lookups work correctly.

Fireface 800 voluntarily maintains resources for tx isochronous communication. It performs reservation of isochronous channel and allocation/update of bandwidth in some cases below: - at a first request to allocation after bus resets - at requests to allocation when further bandwidth is required When request is grant and the unit is prepared, read data from 0x0000801c0008 represents isochronous channel for tx stream, then the unit can handle requests to start communication. If driver send the request without checking the register, the unit takes panic to continue bus resets. The unit starts transmission of tx packets after receiving several rx packets from driver. I note that the unit can process tx/rx packets and generate/record sound regardless of HOST LED.

In case when "nopcomp" pppd option is not enabled, PFC (pcomp) can be negotiated during LCP handshake, and L2TP driver in kernel will receive PPP packets with compressed Protocol field, which in turn leads to next error: Protocol Rejected (unsupported protocol 0x2145) because instead of Protocol=0x0021 in PPP packet there will be Protocol=0x21.

We can partially address that when the function pointer refers to a builtin symbol resorting to a list of tests vs well-known builtin function and direct calls. Experimental results show that replacing a single indirect call via retpoline with several branches and a direct call gives performance gains even when multiple branches are added - 5 or more, as reported in [2]. This may lead to some uglification around the indirect calls. In netconf 2018 Eric Dumazet described a technique to hide the most relevant part of the needed boilerplate with some macro help. This series is a [re-]implementation of such idea, exposing the introduced helpers in a new header file. They are later leveraged to avoid the indirect call overhead in the GRO path, when possible. Overall this gives > 10% performance improvement for UDP GRO benchmark and smaller but measurable for TCP syn flood. The added infra can be used in follow-up patches to cope with retpoline overhead in other points of the networking stack (e.g. at the qdisc layer) and possibly even in other subsystems. v2 -> v3: - fix build error with CONFIG_IPV6=m v1 -> v2: - list explicitly the builtin function names in INDIRECT_CALL_*(), as suggested by Ed Cree - expand the recipients list rfc -> v1: - use branch prediction hints, as suggested by Eric [1] http://vger.kernel.org/netconf2018_files/PaoloAbeni_netconf2018.pdf [2] https://linuxplumbersconf.org/event/2/contributions/99/attachments/98/117/lpc18_paper_af_xdp_perf-v2.pdf ==================== Signed-off-by: David S.

"netsec 522d0000.ethernet eth0: netsec_netdev_start_xmit: TxQFull!" appears on dmesg but the interface never recovers. It requires an ifconfig down/up to make the interface usable again. The reason that triggers this, is a race condition between .ndo_start_xmit and the napi completion. The available budget is calculated first and indicates the queue is full. Due to a costly netif_err() the queue is not stopped in time while the napi completion runs, clears the irq and frees up descriptors, thus the queue never wakes up again. Fix this by moving the print after stopping the queue, make the print ratelimited, add barriers and check for cleaned descriptors.. Signed-off-by: Ilias Apalodimas Signed-off-by: David S.

While the logic is fine, the value of 'timeout_ms' is given by the core and actually correspond to the maximum time the NAND chip will take to complete the operation. Assuming there is no overhead in the propagation of the interrupt signal to the the NAND controller (through the Ready/Busy line), this delay does not take into account the latency of the operating system. For instance, for a page write, the delay given by the core is rounded up to 1ms. Hence, when the machine is over loaded, there is chances that this timeout will be reached. There are two ways to solve this issue that are not incompatible: 1/ Enlarge the timeout value (if so, how much?). 2/ Check after the waiting method if we did not miss any interrupt because of the OS latency (an interrupt is still pending). In this case, we assume the operation exited successfully. We choose the second approach that is a must in all cases, with the possibility to also modify the timeout value to be, e.g. at least 1 second in all cases.

Since Kconfig has no terminator for a config block, detecting the end of config_stmt is not easy. For example, there are two ways for handling the error in the following code: 1 config FOO 2 = [A] Print "unknown option" error, assuming the line 2 is a part of config_option_list [B] Print "invalid statement", assuming the line 1 is reduced into a config_stmt by itself Bison actually chooses [A] because it performs the shift rather than the reduction where both are possible. However, there is no reason to choose one over the other. Let's remove the option_error, and let it fall back to [B].

The location of this error recovery is ambiguous. For example, there are two ways to interpret the following code: 1 config FOO 2 bool "foo" [A] Both lines are reduced together into a config_stmt. [B] The only line 1 is reduced into a config_stmt, and the line 2 matches to "option_name error T_EOL" Of course, we expect [A], but [B] could be grammatically possible. Kconfig has no terminator for a config block. So, we cannot detect its end until we see a non-property keyword. People often insert a blank line between two config blocks, but it is just a coding convention. Blank lines are actually allowed anywhere in Kconfig files. The real error is when a property keyword appears right after "endif", "endchoice", "endmenu", "source", "comment", or variable assignment. Instead of fixing the grammatical ambiguity, I chose to simply remove this error recovery. The difference is unexpected option "bool" ... is turned into a more generic message: invalid statement Signed-off-by: Masahiro Yamada commit 723679339d087d79e36c0af67f4be84d866fee20 Author: Masahiro Yamada Date: Tue Dec 11 20:00:51 2018 +0900 kconfig: warn no new line at end of file It would be nice to warn if a new line is missing at end of file.

I know there are some false negative cases. For example, no warning is displayed when the last line contains some whitespaces/comments, but no new line. Yet, this commit works well for most cases.

It fits well for the internal BTF verbose log purpose which is focusing on type. For example, offset == 0 => "(anon)" => anonymous type/name. Returning non-NULL for the bad offset case is needed during the BTF verification process because the BTF verifier may complain about another field first before discovering the name_off is invalid. However, it may not be ideal for the newer use case which does not necessary mean type name. For example, when logging line_info in the BPF verifier in the next patch, it is better to log an empty src line instead of logging "(anon)". The existing bpf_name_by_offset() is renamed to __bpf_name_by_offset() and static to btf.c. A new bpf_name_by_offset() is added for generic context usage. It returns "\0" for name_off == 0 (note that btf->strings[0] is "\0") and NULL for invalid offset. It allows the caller to decide what is the best output in its context. The new btf_name_by_offset() is overlapped with btf_name_offset_valid(). Hence, btf_name_offset_valid() is removed from btf.h to keep the btf.h API minimal. The existing btf_name_offset_valid() usage in btf.c could also be replaced later.

Duplication is not required if the source is the bond device, since in this case it is assumed that the bond and the uplink netdevs share the same TC block, and thus duplication will occur naturally by the stack.

Currently, the route lookup code on the encapsulation offload path assumes that same switchdev id for the source and dest devices means that the dest is also mlx5 HW netdev. This doesn't hold anymore when we align the switchdev Id of the uplinks to be same, which in turn causes the bond/team to return that id to the caller. As such, enhance the relevant check to take into account the uplink lag case.

With upcoming support for uplink LAG, we have two HW rules per one logical SW (TC) rule. Although the HW supports attaching one counter to multiple rules, we are allocating counter per HW rule. We need this separation for two reasons: 1. "flow eswitch" counter affinity HW require the counter to be allocated on the device where the eswitch rule is set. 2. for some use-cases (multi-path routing) each HW flow relates to different neighbour, hence our neigh update logic must have a per-rule HW accountant in order to provide the proper feedback to the kernel.

To cope with the fact that the SW model might use logical SW port (e.g uplink team or bond) but we have two HW ports with e-switch on each, there are cases where in order to offload a SW TC rule we need to duplicate it to two HW flows. Since each HW rule has its own counter we also aggregate the counter of both rules when a flow stats query is executed from user-space. Introduce the changes for the different elements (add/delete/stats), currently nothing is duplicated.

To solve this, add a way for archs to fixup the reading of these module kallsyms values, and use that to clear the lowest bit for function symbols on Thumb-2.

Unfortunately, the field is quite large, (e.g., 4352 bytes on my current setup). This bloats the kvm_vcpu_arch struct for x86 into an order 3 memory allocation, which can become a problem on overcommitted machines. Thus, this patch moves the fpu state outside of the kvm_vcpu_arch struct. With this patch applied, the kvm_vcpu_arch struct is reduced to 15168 bytes for vmx on my setup when building the kernel with kvmconfig.

However, this is redundant to the 'struct fpu' field, called fpu, embedded in the task struct, via the thread field. Thus, this patch removes the user_fpu field from the kvm_vcpu_arch struct and replaces it with the task struct's fpu field. This change is significant because the fpu struct is actually quite large. For example, on the system used to develop this patch, this change reduces the size of the vcpu_vmx struct from 23680 bytes down to 19520 bytes, when building the kernel with kvmconfig. This reduction in the size of the vcpu_vmx struct moves us closer to being able to allocate the struct at order 2, rather than order 3.

With direct mode we notify the guest by asserting APIC irq instead of sending a SynIC message. The implementation uses existing vec_bitmap for letting lapic code know that we're interested in the particular IRQ's EOI request. We assume that the same APIC irq won't be used by the guest for both direct mode stimer and as sint source (especially with AutoEOI semantics). It is unclear how things should be handled if that's not true. Direct mode is also somewhat less expensive; in my testing stimer_send_msg() takes not less than 1500 cpu cycles and stimer_notify_direct() can usually be done in 300-400.

However, this is unnecessary and even undesirable for messages generated by SynIC timers in periodic mode: if the period is short enough compared to the time the guest spends in the timer interrupt handler, so the timer ticks start piling up, the excessive interactions due to this notification and retried message delivery only makes the things worse. [This was observed, in particular, with Windows L2 guests setting (temporarily) the periodic timer to 2 kHz, and spending hundreds of microseconds in the timer interrupt handler due to several L2->L1 exits; under some load in L0 this could exceed 500 us so the timer ticks started to pile up and the guest livelocked.] Relieve the situation somewhat by not retrying message delivery for periodic SynIC timers. This appears to remain within the "lazy" lost ticks policy for SynIC timers as implemented in KVM. Note that it doesn't solve the fundamental problem of livelocking the guest with a periodic timer whose period is smaller than the time needed to process a tick, but it makes it a bit less likely to be triggered.

The correct order would be to first set .msg_pending, then atomically replace .message_type if it was zero, and then clear .msg_pending if the previous step was successful. But this all is done in vcpu context so the whole update looks atomic to the guest (it's assumed to only access the message page from this cpu), and therefore can be done in whatever order is most convenient (and is also the reason why the incorrect order didn't trigger any bugs so far). While at this, also switch to kvm_vcpu_{read,write}_guest_page, and drop the no longer needed synic_clear_sint_msg_pending.

This issue was mainly ignored so far because either the regulator was a static regulator that would be providing power anyway, or the bank was used for a feature unsupported so far (CSI). For the odd cases, enabling it in the bootloader was the preferred option. However, now that we are starting to support those features, and that we can't really rely on the bootloader for this, we need to model those regulators as such in the DT. This is slightly more complicated than what it looks like, since some regulators will be tied to the PMIC, and in order to have access to the PMIC bus, you need to mux its pins, which will need the pinctrl driver, that needs the regulator driver to be registered. And this is how you get a circular dependency. In practice however, the hardware cannot fall into this case since it would result in a completely unusable bus. In order to avoid that circular dependency, we can thus get and enable the regulators at pin_request time. We'll then need to account for the references of all the pins of a particular branch to know when to put the reference, but it works pretty nicely once implemented.

Note that LSbit toggling only alternates between two registers during the IO, it is not the same as address auto-increment.

This is incorrect at there are chips with 16 GPIOs which require the auto-increment bit. The PCA9575, according to NXP datasheet rev. 4.2 from 16 April 2015, section 7.3 Command Register, the bit 7 in command register is the auto-increment bit, which allows programming multiple registers sequentially. Set this bit both in pca953x_gpio_set_multiple(), where it fixes the multi register programming, and in pca957x_write_regs_16(), where is simplifies the function.

First, and less important, it can take kvm->mmu_lock for an extended period of time. Second, its user can actually see many false positives in some cases. The latter is due to a benign race like this: 1. KVM_GET_DIRTY_LOG returns a set of dirty pages and write protects them. 2. The guest modifies the pages, causing them to be marked ditry. 3. Userspace actually copies the pages. 4. KVM_GET_DIRTY_LOG returns those pages as dirty again, even though they were not written to since (3). This is especially a problem for large guests, where the time between (1) and (3) can be substantial. This patch introduces a new capability which, when enabled, makes KVM_GET_DIRTY_LOG not write-protect the pages it returns. Instead, userspace has to explicitly clear the dirty log bits just before using the content of the page. The new KVM_CLEAR_DIRTY_LOG ioctl can also operate on a 64-page granularity rather than requiring to sync a full memslot; this way, the mmu_lock is taken for small amounts of time, and only a small amount of time will pass between write protection of pages and the sending of their content.

Some data is now available even for HT/VHT frames, so the info type in the metadata was changed. This change isn't backwards compatible, but 1) the firmware with the old API was never released; 2) the only overlap in the info type field is from the old type of TB to the new of HT, so this basically just means that with older FW and newer driver the data will be considered missing. While at it, remove the extra code to set the LTF syms corresponding to the streams and use the data from the device instead - we don't really need this in any case other than when we have it from the device.

This commit extends that to also handle the performance state requirement(s) put on the master genpd by its sub-domains. There is a separate value required for each master that the genpd has and so a new field is added to the struct gpd_link (link->performance_state), which represents the link between a genpd and its master. The struct gpd_link also got another field prev_performance_state, which is used by genpd core as a temporary variable during transitions. On a call to dev_pm_genpd_set_performance_state(), the genpd core first updates the performance state of the masters of the device's genpd and then updates the performance state of the genpd. The masters do the same and propagate performance state updates to their masters before updating their own. The performance state transition from genpd to its master is done with the help of dev_pm_opp_xlate_performance_state(), which looks at the OPP tables of both the domains to translate the state.

Since 0 is a valid performance state (representing off), it would be better if this routine returns negative values on error. That will also make it behave similar to dev_pm_opp_xlate_performance_state(), which also returns performance states and returns negative values on error. Change the return type of the function to "int" in order to return negative values. This doesn't have any users for now and so no other part of the kernel will be impacted with this change.

Introduce a new helper dev_pm_opp_xlate_performance_state() which will be used to translate from performance state of a device (or genpd sub-domain) to another device (or master genpd). Normally the src_table (of genpd sub-domain) will have the "required_opps" property set to point to one of the OPPs in the dst_table (of master genpd), but in some cases the genpd and its master have one to one mapping of performance states and so none of them have the "required-opps" property set. Return the performance state of the src_table as it is in such cases.

The assumptions creates an unnecessary limitation at this point, for both consumers and providers, but more importantly it also makes the code more complicated. Therefore, let's simplify the code to allow setting a performance state, by invoking the ->set_performance_state() callback, no matter whether the PM domain is powered on or off. Do note, this change means genpd providers needs to restore the performance state themselves during power on, via the ->power_on() callback. Moreover, they may also need to check that the PM domain is powered on, from their ->set_performance_state() callback, before deciding to update the state.

The symptom is a NULL pointer dereference in __find_linux_pte() called from kvm_unmap_radix() with kvm->arch.pgtable == NULL. Looking at kvmppc_switch_mmu_to_hpt(), it does indeed clear kvm->arch.pgtable (via kvmppc_free_radix()) before setting kvm->arch.radix to NULL, and there is nothing to prevent kvm_unmap_hva_range_hv() or the other MMU callback functions from being called concurrently with kvmppc_switch_mmu_to_hpt() or kvmppc_switch_mmu_to_radix(). This patch therefore adds calls to spin_lock/unlock on the kvm->mmu_lock around the assignments to kvm->arch.radix, and makes sure that the partition-scoped radix tree or HPT is only freed after changing kvm->arch.radix. This also takes the kvm->mmu_lock in kvmppc_rmap_reset() to make sure that the clearing of each rmap array (one per memslot) doesn't happen concurrently with use of the array in the kvm_unmap_hva_range_hv() or the other MMU callbacks.

Miller Date: Thu Dec 13 18:41:39 2018 -0800 Merge branch 'Introduce-NETDEV_PRE_CHANGEADDR' Petr Machata says: ==================== Introduce NETDEV_PRE_CHANGEADDR Spectrum devices have a limitation that all router interfaces need to have the same address prefix. In Spectrum-1, the requirement is for the initial 38 bits of all RIFs to be the same, in Spectrum-2 the limit is 36 bits. Currently violations of this requirement are not diagnosed. At the same time, if the condition is not upheld, the mismatched MAC address ends up overwriting the common prefix, and all RIF MAC addresses silently change to the new prefix. It is therefore desirable to be able at least to diagnose the issue, and better to reject attempts to change MAC addresses in ways that is incompatible with the device. Currently MAC address changes are notified through emission of NETDEV_CHANGEADDR, which is done after the change. Extending this message to allow vetoing is certainly possible, but several other notification types have instead adopted a simple two-stage approach: first a "pre" notification is sent to make sure all interested parties are OK with the change that's about to be done. Then the change is done, and afterwards a "post" notification is sent. This dual approach is easier to use: when the change is vetoed, nothing has changed yet, and it's therefore unnecessary to roll anything back. Therefore this patchset introduces it for NETDEV_CHANGEADDR as well. One prominent path to emitting NETDEV_CHANGEADDR is through dev_set_mac_address(). Therefore in patch #1, give this function an extack argument, so that a textual reason for rejection (or a warning) can be communicated back to the user. In patch #2, add the new notification type. In patch #3, have dev.c emit the notification for instances of dev_addr change, or addition of an address to dev_addrs list. In patches #4 and #5, extend the bridge driver to handle and emit the new notifier. In patch #6, change IPVLAN to emit the new notifier. Likewise for bonding driver in patches #7 and #8. Note that the team driver doesn't need this treatment, as it goes through dev_set_mac_address(). In patches #9, #10 and #11 adapt mlxsw to veto MAC addresses on router interfaces, if they violate the requirement that all RIF MAC addresses have the same prefix. Finally in patches #12 and #13, add a test for vetoing of a direct change of a port device MAC, and indirect change of a bridge MAC. ==================== Signed-off-by: David S.

Extending this message to allow vetoing is certainly possible, but several other notification types have instead adopted a simple two-stage approach: first a "pre" notification is sent to make sure all interested parties are OK with a change that's about to be done. Then the change is done, and afterwards a "post" notification is sent. This dual approach is easier to use: when the change is vetoed, nothing has changed yet, and it's therefore unnecessary to roll anything back. Therefore adopt it for NETDEV_CHANGEADDR as well. To that end, add NETDEV_PRE_CHANGEADDR and an info structure to go along with it. Signed-off-by: Petr Machata Acked-by: Jiri Pirko Reviewed-by: Ido Schimmel Signed-off-by: David S.

The logic uses KSFT_KHDR_INSTALL and top_srcdir as controls to initialize variables and include files to run headers_install from the top level Makefile. There are a few problems with this logic. 1. Exposes top_srcdir to all tests 2. Common logic impacts all tests 3. Uses KSFT_KHDR_INSTALL, top_srcdir, and khdr in an adhoc way. Tests add "khdr" dependency in their Makefiles to TEST_PROGS_EXTENDED in some cases, and STATIC_LIBS in other cases. This makes this framework confusing to use. The common logic that runs for all tests even when KSFT_KHDR_INSTALL isn't defined by the test. top_srcdir is initialized to a default value when test doesn't initialize it. It works for all tests without a sub-dir structure and tests with sub-dir structure fail to build. e.g: make -C sparc64/drivers/ or make -C drivers/dma-buf ../../lib.mk:20: ../../../../scripts/subarch.include: No such file or directory make: *** No rule to make target '../../../../scripts/subarch.include'. Stop. There is no reason to require all tests to define top_srcdir and there is no need to require tests to add khdr dependency using adhoc changes to TEST_* and other variables. Fix it with a consistent use of KSFT_KHDR_INSTALL and top_srcdir from tests that have the dependency on headers_install. Change common logic to include khdr target define and "all" target with dependency on khdr when KSFT_KHDR_INSTALL is defined. Only tests that have dependency on headers_install have to define just the KSFT_KHDR_INSTALL, and top_srcdir variables and there is no need to specify khdr dependency in the test Makefiles.

Factor these out into general dma-mapping code so that they can be referenced from other common code paths. In the process, we can prune all the optional callbacks which just do the same thing as the default behaviour, and fill in .map_resource for completeness.

We have to change the value of __NR_Linux_syscalls, if we add or delete a system call. One of the patch in this patch series has a script which will generate a uapi header based on syscall.tbl file. The syscall.tbl file contains the total number of system calls information. So we have two option to update __NR- _Linux_syscalls value. 1. Update __NR_Linux_syscalls in asm/unistd.h manually by counting the no.of system calls. No need to update __NR_Linux_syscalls until we either add a new system call or delete existing system call. 2. We can keep this feature it above mentioned script, that will count the number of syscalls and keep it in a generated file. In this case we don't need to expli- citly update __NR_Linux_syscalls in asm/unistd.h file. The 2nd option will be the recommended one. For that, I added the __NR_syscalls macro in uapi/asm/unistd.h along with __NR_Linux_syscalls. The macro __NR_syscalls also added for making the name convention same across all architecture. While __NR_syscalls isn't strictly part of the uapi, having it as part of the generated header to simplifies the implementation. We also need to enclose this macro with #ifdef __KERNEL__ to avoid side effects.

In cases where legacy hardware and software support within the guest is not needed, Qemu should be able to boot directly into the uncompressed Linux kernel binary without the need to run firmware. There already exists an ABI to allow this for Xen PVH guests and the ABI is supported by Linux and FreeBSD: https://xenbits.xen.org/docs/unstable/misc/pvh.html This patch enables Qemu to use that same entry point for booting KVM guests.

The original design for PVH entry in Xen guests relies on being able to obtain the memory map from the hypervisor using a hypercall. When we extend the PVH entry ABI to support other hypervisors like Qemu/KVM, a new mechanism will be added that allows the guest to get the memory map without needing to use hypercalls. For Xen guests, the hypercall approach will still be supported. In preparation for adding support for other hypervisors, we can move the code that uses hypercalls into the Xen specific file. This will allow us to compile kernels in the future without CONFIG_XEN that are still capable of being booted as a Qemu/KVM guest via the PVH entry point.

We already handle the case where we have a single interrupt in the mask register and a separate type configuration register. Add a new switch to regmap_irq_chip which tells the framework to use the mask_base address for configuring the edge of the interrupts that define type_falling/rising_mask values. For such interrupts we never update the type_base bits. For interrupts that don't define type masks or their regmap irq chip doesn't set the type_in_mask to true everything stays the same.

This patch has the kernel strip the PAC from user stackframes when the in-kernel unwinder is used. This only affects the LR value, and not the FP. This only affects the in-kernel unwinder.

The number and position of these bits depends on the configured TCR_ELx.TxSZ and whether tagging is enabled. ARMv8.3 allows tagging to differ for instruction and data pointers. For userspace debuggers to unwind the stack and/or to follow pointer chains, they need to be able to remove the PAC bits before attempting to use a pointer. This patch adds a new structure with masks describing the location of the PAC bits in userspace instruction and data pointers (i.e. those addressable via TTBR0), which userspace can query via PTRACE_GETREGSET. By clearing these bits from pointers (and replacing them with the value of bit 55), userspace can acquire the PAC-less versions. This new regset is exposed when the kernel is built with (user) pointer authentication support, and the address authentication feature is enabled. Otherwise, the regset is hidden.

For VHE kernels host EL0 (TGE && E2H) is unaffected by these settings, and it doesn't matter how we configure HCR_EL2.{API,APK}, so we don't bother setting them.

Any value larger than CUTOFF_WRITEBACK will be fixed up to 40. Now cutof writeback limit is a dynamic value bch_cutoff_writeback, so the range of writeback_percent can be a more flexible range as [0, bch_cutoff_writeback]. The flexibility is, it can be expended to a larger or smaller range than [0, 40], depends on how value bch_cutoff_writeback is specified. The default value is still strongly recommended to most of users for most of workloads. But for people who want to do research on bcache writeback perforamnce tuning, they may have chance to specify more flexible writeback_percent in range [0, 70].

Most of time these they work fine, but when people want to do research on bcache writeback mode performance tuning, there is no chance to modify the soft and hard cutoff writeback values. This patch introduces two module parameters bch_cutoff_writeback_sync and bch_cutoff_writeback which permit people to tune the values when loading bcache.ko. If they are not specified by module loading, current values CUTOFF_WRITEBACK_SYNC and CUTOFF_WRITEBACK will be used as default and nothing changes. When people want to tune this two values, - cutoff_writeback can be set in range [1, 70] - cutoff_writeback_sync can be set in range [1, 90] - cutoff_writeback always <= cutoff_writeback_sync The default values are strongly recommended to most of users for most of workloads. Anyway, if people wants to take their own risk to do research on new writeback cutoff tuning for their own workload, now they can make it.

This results in high latency responses from the Memory Read TLP and potential Completion Timeout (CTO). Add support for MRPC DMA mode, including related macro definitions and data structures and code to: * Retrieve MRPC DMA mode version from adapter firmware * Allocate DMA buffer, register ISR, and enable DMA during init * Check MRPC execution status and get execution results from DMA buffer * Release DMA buffer and disable DMA function when unloading module MRPC DMA mode is a new feature of firmware, and the driver will fall back to MRPC normal mode if there is no support in the legacy firmware. Add a module parameter, "use_dma_mrpc", to select between MRPC DMA mode and MRPC normal mode. Since the driver automatically detects DMA support in the firmware, this parameter is just for debugging and testing. Include so that readq/writeq is replaced by two readl/writel on systems that do not support it.

However the credit number may be changed that is based on packet pool length and will send BRCMF_E_FIFO_CREDIT_MAP event to notify host driver updates the credit numbers during interface up. The purpose of this patch is making host driver has ability of updating the credit numbers when receiving the BRCMF_E_FIFO_CREDIT_MAP event.

At least, they give reasonable results when I parse them this way. So this patch adds support for RX_BITRATE to our station info dump. Along the way, I add legacy bitrate parsing into the same function, using the debugfs code (mwifiex_histogram_read() and mwifiex_adjust_data_rate()) as reference. Additionally, to satisfy the requirements of NL80211_STA_INFO_RX_BITRATE, I skip logging the bitrate of multicast packets. This shouldn't add a lot of overhead to the RX path, as there are already several similar 802.3 header checks in this same codepath. We can also bias the branch behavior to favor unicast, as that's the common performance-sensitive case. I'd consider this support somewhat experimental, as I have zero documentation from Marvell. But the existing driver code gives me good reason to think this is correct. I've tested this on a few different 802.11{a,b,g,n,ac} networks, and the reported bitrates look good to me.

It currently assumes it's dealing only with TX bitrate, but the RX bitrate looks to be the same, so refactor this function to be reusable.

Placing the msb at bit 28 in the toddr driver just filters out the parity, user, channel status and validity bits.

Thus only the first recvmsg() returns data, and it may only include a subset of the crypto algorithms even if the user buffer passed to recvmsg() is large enough to hold all of them. Fix this by using one of the arguments in the netlink_callback structure to keep track of the current position in the algorithm list. Then userspace can do multiple recvmsg() on the socket after sending the dump request. This is the way netlink dumps work elsewhere in the kernel; it's unclear why this was different (probably just an oversight). Also fix an integer overflow when calculating the dump buffer size hint.

The ap_scan_bus() function is large, so this patch splits the code by introducing a new new function _ap_scan_bus_adapter() which deals with just one adapter and thus reduces the scan function code complexity. Now the AP bus scan can handle a type change of an crypto adapter on the fly (e.g. from CEX5 to CEX6). This may be the case with newer versions of zVM where the card may be pure virtual and a type change is just one click. However a type or function change requires to unregister all queue devices and the card device and re-register them. Comments around the AP bus scan code have been added and/or improved to provide some hopefully useful hints about what the code is actually doing.

Driving a card or queue offline and online again does only toggle the 'software' online state. The only way to trigger a (hardware) reset is by running hot-unplug/hot-plug for example on the HMC. This patch makes the queue reset attribute in sysfs writable. Writing into this attribute triggers a reset on the AP queue's state machine. So the AP queue is flushed and state machine runs through the initial states which cause a reset (PQAP(RAPQ)) and a re-registration to interrupts (PQAP(AQIC)) if available. The reset sysfs attribute is writable by root only. So only an administrator is allowed to initiate a reset of AP queues. Please note that the queue's counter values are left untouched by the reset.

Thomas Gleixner suggested a solution based on a bitfield where we set a bit for every offset associated with an interrupt that should be fired and then iterate over all set bits in the interrupt handler. This is a slightly modified solution using a bitmap so that we don't impose a limit on the number of interrupts one can allocate with irq_sim.

Later, two other helpers have been added to handle IRQ domains on top of MSI domains: platform_msi_domain_alloc() platform_msi_domain_free() Seen from the outside, the logic is pretty close with the former helpers and people used it with the same logic as before: a platform_msi_domain_alloc() call should be balanced with a platform_msi_domain_free() call. While this is probably what was intended to do, the platform_msi_domain_free() does not remove/free the IRQ descriptor(s) created/inserted in platform_msi_domain_alloc(). One effect of such situation is that removing a module that requested an IRQ will let one orphaned IRQ descriptor (with an allocated MSI entry) in the device descriptors list. Next time the module will be inserted back, one will observe that the allocation will happen twice in the MSI domain, one time for the remaining descriptor, one time for the new one. It also has the side effect to quickly overshoot the maximum number of allocated MSI and then prevent any module requesting an interrupt in the same domain to be inserted anymore. This situation has been met with loops of insertion/removal of the mvpp2.ko module (requesting 15 MSIs each time).

Laptops such as the Matebook X have non functioning hotkeys. Whereas newer laptops such as the Matebook X Pro come with working hotkeys out of the box. Old laptops, such as the Matebook X, report hotkey events through ACPI device "\WMI0". However, new laptops, such as the Matebook X Pro, does not have this WMI device. All the hotkeys on the Matebook X Pro work fine without this patch except (micmute, wlan, and huawei key). These keys and the brightness keys report events to "\AMW0" ACPI device. One problem is that brightness keys on the Matebook X Pro work without this patch. This results in reporting two brightness key press events one is captured by ACPI and another by this driver. A solution would be to check if such event came from the "\AMW0" WMI driver then skip reporting event. Another solution would be to leave this to user-space to handle. Which can be achieved by using "hwdb" tables and remap those keys to "unknown". This solution seems more natural to me because it leaves the decision to user-space.

For example, it may be used as a bootloader needing to kexec a target kernel or it may need to kexec a crashdump kernel. In such cases, it may want to verify the signature of the next kernel image. It is further possible that the kernel image is signed with third party keys which are stored as platform or firmware keys in the 'db' variable. The kernel, however, can not directly verify these platform keys, and an administrator may therefore not want to trust them for arbitrary usage. In order to differentiate platform keys from other keys and provide the necessary separation of trust, the kernel needs an additional keyring to store platform keys. This patch creates the new keyring called ".platform" to isolate keys provided by platform from keys by kernel. These keys are used to facilitate signature verification during kexec. Since the scope of this keyring is only the platform/firmware keys, it cannot be updated from userspace. This keyring can be enabled by setting CONFIG_INTEGRITY_PLATFORM_KEYRING.

Miller Date: Wed Dec 12 16:34:22 2018 -0800 Merge branch 'Pass-extack-to-SWITCHDEV_PORT_OBJ_ADD' Petr Machata says: ==================== Pass extack to SWITCHDEV_PORT_OBJ_ADD Drivers may need to do validation as a result of port object addition. An example is mlxsw, which needs to check the configuration of a VXLAN device attached to an offloaded bridge. Without a mapped VLAN, the invalidity of the device is not important, but as soon as a pvid, untagged VLAN is configured for the device, it has to be validated and offloaded. Should the validation fail, there's currently no way to communicate details of the failure to the user, beyond an error number. Because currently, extack is not available at all in that area of code, this patch starts down at the RTNL level and progresses up towards the driver(s). In patch #1, ndo_bridge_setlink is updated to include extack, and callbacks of all clients are updated as well (ignoring the argument). In patch #2, the bridge driver is updated to propagate the extack through to the switchdev border, br_switchdev_port_vlan_add(). Patches #3, #4 and #5 then gradually extend switchdev to pass the extack argument through to the switchdev blocking notifier chain. Patches #6 and #7 then update mlxsw to pass the extack argument from VXLAN events resp. port events on to mlxsw_sp_bridge_8021q_vxlan_join(). Finally in patches #8 and #9, the code paths from the previous two patches are verified to yield an error message. v2: - Patch #1: - In ndo_bridge_setlink(), keep the whole extack declaration on the same line. ==================== Signed-off-by: David S.

This code path is used when a VLAN is added to a port netdevice if there already is an unoffloadable VXLAN device with that VLAN mapped. mlxsw_sp_bridge_8021d_port_join() is updated to obey the new interfaces changed by the abovementioned code, propagating extack ultimately from NETDEV_CHANGEUPPER events.

It's a bit of a rough first pass that'll get improved in future releases as a finish figuring out some of the other HW changes, but it's good enough as it stands for modesetting and suspend/resume etc. Acceleration bring-up is incomplete due to NVIDIA not yet having provided FW images for me to use, though command submission and copy engines are functional already.

That changed when we forked out support for the latter into the export.h file. This means we should be able to reduce the usage of module.h in code that is obj-y Makefile or bool Kconfig. The advantage in removing such instances is that module.h itself sources about 15 other headers; adding significantly to what we feed cpp, and it can obscure what headers we are effectively using. Since module.h might have been the implicit source for init.h (for __init) and for export.h (for EXPORT_SYMBOL) we consider each instance for the presence of either and replace as needed.

In this case, that file is "encrypted.c" and it already has the MODULE_LICENSE that we are removing here. Since the file does EXPORT_SYMBOL, we add export.h - and build tests show that module.h (which includes everything) was hiding an implicit use of string.h - so that is added as well.

This is a firmware limitation. Delayed MemRd completions are a problem for systems with a low Completion Timeout (CTO). The current driver checks the MRPC status immediately after submitting an MRPC command, which results in a delayed MemRd completion that may cause a Completion Timeout. Remove the immediate status check and rely on the check after receiving an interrupt or timing out. This is only a software workaround to the READ issue and a proper fix of this should be done in firmware.

If we return an error we end up with acpi_default_enumeration() still creating a platform- device for the device and we end up with the device still being used but without the special LPSS related handling which is not useful. Specicifically ignoring the error fixes the touchscreen no longer working after a suspend/resume on a Prowise PT301 tablet. This tablet has a broken _PS0 method on the touchscreen's I2C controller, causing acpi_device_fix_up_power() to fail, causing fallback to standard platform-dev handling and specifically causing acpi_lpss_save/restore_ctx to not run. The I2C controllers _PS0 method does actually turn on the device, but then does some more nonsense which fails when run during early boot trying to use I2C opregion handling on another not-yet registered I2C controller.

This caused the SMBus PCI device to stay in D0 with /sys/devices/.../power/runtime_status showing "error" when the runtime PM framework attempted to autosuspend the device. This is due to PCI bus runtime PM, which checks for driver runtime PM callbacks and returns -ENOSYS if they are not set. Since i2c-i801.c doesn't need to do anything device-specific for runtime PM, Jean Delvare proposed this be fixed in the PCI core rather than adding dummy runtime PM callback functions in the PCI drivers. Change pci_pm_runtime_suspend()/pci_pm_runtime_resume() so they allow changing the PCI device power state during runtime PM transitions even if the driver supplies no runtime PM callbacks. This fixes the runtime PM regression on i2c-i801.c. It is not obvious why the code previously required the runtime PM callbacks. The test has been there since the code was introduced by 6cbf82148ff2 ("PCI PM: Run-time callbacks for PCI bus type"). On the other hand, a similar change was done to generic runtime PM callbacks in 05aa55dddb9e ("PM / Runtime: Lenient generic runtime pm callbacks").

On SMP kernels, this is impossible since the stack canary value is obtained via a global symbol reference, which means a) all running tasks on all CPUs must use the same value b) we can only modify the value when no kernel stack frames are live on any CPU, which is effectively never. So instead, use a GCC plugin to add a RTL pass that replaces each reference to the address of the __stack_chk_guard symbol with an expression that produces the address of the 'stack_canary' field that is added to struct thread_info. This way, each task will use its own randomized value.

A high volume of cursor updates through this slow code path can cause subsequent page-flips to skip vblank intervals since each individual update is slow. This problem is particularly noticeable for the compton compositor. [How] A fast path for cursor plane updates is added by using DRM asynchronous commit support provided by async_check and async_update. These don't do a full state/flip_done dependency stall and they don't block other commit work. However, DC still expects itself to be single-threaded for anything that can issue register writes. Screen corruption or hangs can occur if write sequences overlap. Every call that potentially perform register writes needs to be guarded for asynchronous updates to work. The dc_lock mutex was added for this.

However, bus resets can be rather slow and a global mutex here is undesirable. Evaluating the potential locking granularity, a per-device mutex provides the best resolution but with multiple devices on a bus all released concurrently, they'll race to acquire each other's mutex, likely resulting in no reset at all if we use trylock. We therefore lock at the granularity of the bus/slot reset as we're only attempting a single reset for this group of devices anyway. This allows much greater scaling as we're bounded in the number of devices protected by a single reflck object.

However, the summary array is stored in row-major order (i.e., like an array in C), so all of these entries are not adjacent, but rather spread across the entire summary file. In the worst case (a full bitmap block), xfs_rtany_summary() has to check every level. This means that on a moderately-used realtime device, an allocation will waste a lot of time finding, reading, and releasing buffers for the realtime summary. In particular, one of our storage services (which runs on servers with 8 very slow CPUs and 15 8 TB XFS realtime filesystems) spends almost 5% of its CPU cycles in xfs_rtbuf_get() and xfs_trans_brelse() called from xfs_rtany_summary(). One solution would be to also store the summary with the dimensions swapped. However, this would require a disk format change to a very old component of XFS. Instead, we can cache the minimum size which contains any extents. We do so lazily; rather than guaranteeing that the cache contains the precise minimum, it always contains a loose lower bound which we tighten when we read or update a summary block. This only uses a few kilobytes of memory and is already serialized via the realtime bitmap and summary inode locks, so the cost is minimal. With this change, the same workload only spends 0.2% of its CPU cycles in the realtime allocator. Signed-off-by: Omar Sandoval Reviewed-by: Darrick J. Wong Signed-off-by: Darrick J.

It was caused by a shutdown during a combined fstress+fsmark workload. The underlying problem is the issue in xfs_inactive_symlink(): the inode is unlocked between the symlink inactivation/truncation and the inode being freed. This opens a window for the inode to be written to disk before it xfs_ifree() removes it from the unlinked list, marks it free in the inobt and zeros the mode. For shortform inodes, the fix is simple. xfs_ifree() clears the data fork state, so there's no need to do it in xfs_inactive_symlink(). This means the shortform fork verifier will not see a zero length data fork as it mirrors the inode size through to xfs_ifree()), and hence if the inode gets written back and the fork verifiers are run they will still see a fork that matches the on-disk inode size. For extent form (remote) symlinks, it is a little more tricky. Here we explicitly set the inode size to zero, so the above race can lead to zero length symlinks on disk. Because the inode is unlinked at this point (i.e. on the unlinked list) and unreferenced, it can never be seen again by a user. Hence when we set the inode size to zeor, also change the type to S_IFREG. xfs_ifree() expects S_IFREG inodes to be of zero length, and so this avoids all the problems of zero length symlinks ever hitting the disk. It also avoids the problem of needing to handle zero length symlink inodes in log recovery to replay the extent free intents and the remaining deferops to free the extents the symlink used. Also add a couple of asserts to warn us if zero length symlinks end up in either the symlink create or inactivation paths. Signed-off-by: Dave Chinner Reviewed-by: Darrick J.

Wong Date: Wed Dec 12 08:46:19 2018 -0800 xfs: split up the xfs_reflink_end_cow work into smaller transactions In xfs_reflink_end_cow, we allocate a single transaction for the entire end_cow operation and then loop the CoW fork mappings to move them to the data fork. This design fails on a heavily fragmented filesystem where an inode's data fork has exactly one more extent than would fit in an extents-format fork, because the unmap can collapse the data fork into extents format (freeing the bmbt block) but the remap can expand the data fork back into a (newly allocated) bmbt block. If the number of extents we end up remapping is large, we can overflow the block reservation because we reserved blocks assuming that we were adding mappings into an already-cleared area of the data fork. Let's say we have 8 extents in the data fork, 8 extents in the CoW fork, and the data fork can hold at most 7 extents before needing to convert to btree format; and that blocks A-P are discontiguous single-block extents: 0......7 D: ABCDEFGH C: IJKLMNOP When a write to file blocks 0-7 completes, we must remap I-P into the data fork. We start by removing H from the btree-format data fork. Now we have 7 extents, so we convert the fork to extents format, freeing the bmbt block. We then move P into the data fork and it now has 8 extents again. We must convert the data fork back to btree format, requiring a block allocation. If we repeat this sequence for blocks 6-5-4-3-2-1-0, we'll need a total of 8 block allocations to remap all 8 blocks. We reserved only enough blocks to handle one btree split (5 blocks on a 4k block filesystem), which means we overflow the block reservation. To fix this issue, create a separate helper function to remap a single extent, and change _reflink_end_cow to call it in a tight loop over the entire range we're completing. As a side effect this also removes the size restrictions on how many extents we can end_cow at a time, though nobody ever hit that. It is not reasonable to reserve N blocks to remap N blocks. Note that this can be reproduced after ~320 million fsx ops while running generic/938 (long soak directio fsx exerciser): XFS: Assertion failed: tp->t_blk_res >= tp->t_blk_res_used, file: fs/xfs/xfs_trans.c, line: 116 Call Trace: xfs_trans_dup+0x211/0x250 [xfs] xfs_trans_roll+0x6d/0x180 [xfs] xfs_defer_trans_roll+0x10c/0x3b0 [xfs] xfs_defer_finish_noroll+0xdf/0x740 [xfs] xfs_defer_finish+0x13/0x70 [xfs] xfs_reflink_end_cow+0x2c6/0x680 [xfs] xfs_dio_write_end_io+0x115/0x220 [xfs] iomap_dio_complete+0x3f/0x130 iomap_dio_rw+0x3c3/0x420 xfs_file_dio_aio_write+0x132/0x3c0 [xfs] xfs_file_write_iter+0x8b/0xc0 [xfs] __vfs_write+0x193/0x1f0 vfs_write+0xba/0x1c0 ksys_write+0x52/0xc0 do_syscall_64+0x50/0x160 entry_SYSCALL_64_after_hwframe+0x49/0xbe Signed-off-by: Darrick J.

A certain amount of grammatical ambiguity comes from how to reduce excessive T_EOL tokens. Let's take a look at the example code below: 1 config A 2 bool "a" 3 4 depends on B 5 6 config B 7 def_bool y The line 3 is melt into "config_option_list", but the line 5 can be either a part of "config_option_list" or "common_stmt" by itself. Currently, the lexer converts '\n' to T_EOL verbatim. In Kconfig, a new line works as a statement terminator, but new lines in empty lines are not critical since empty lines (or lines that contain only whitespaces/comments) are just no-op. If the lexer simply discards no-op lines, the parser will not be bothered by excessive T_EOL tokens. Of course, this means we are shifting the complexity from the parser to the lexer, but it is much easier than tackling on shift/reduce conflicts. I introduced the second stage lexer to tweak the behavior. Discard T_EOL if the previous token is T_EOL or T_HELPTEXT. Two T_EOL tokens in a row is meaningless. T_HELPTEXT is a special token that is reduced without T_EOL.

Since memory hotplug is fairly tightly coupled to sparsemem, we tweak pfn_valid() to also cross-check the presence of a section in the manner of the generic implementation, before falling back to memblock to check for no-map regions within a present section as before. By having arch_add_memory(() create the linear mapping first, this then makes everything work in the way that __add_section() expects. We expect hotplug to be ACPI-driven, so the swapper_pg_dir updates should be safe from races by virtue of the global device hotplug lock.

Unfortunately, when patching in the LSE sequence for a value-returning pcpu atomic, the argument registers are the wrong way round. The implementation of this_cpu_add_return() therefore ends up adding uninitialised stack to the percpu variable and returning garbage. As it turns out, there aren't very many users of the value-returning percpu atomics in mainline and we only spotted this due to a failure in the kprobes selftests. In this case, when attempting to single-step over the out-of-line instruction slot, the debug monitors would not be enabled because calling this_cpu_inc_return() on the kernel debug monitor refcount would fail to detect the transition from 0. We would consequently execute past the slot and take an undefined instruction exception from the kernel, resulting in a BUG: | kernel BUG at arch/arm64/kernel/traps.c:421! | PREEMPT SMP | pc : do_undefinstr+0x268/0x278 | lr : do_undefinstr+0x124/0x278 | Process swapper/0 (pid: 1, stack limit = 0x(____ptrval____)) | Call trace: | do_undefinstr+0x268/0x278 | el1_undef+0x10/0x78 | 0xffff00000803c004 | init_kprobes+0x150/0x180 | do_one_initcall+0x74/0x178 | kernel_init_freeable+0x188/0x224 | kernel_init+0x10/0x100 | ret_from_fork+0x10/0x1c Fix the argument order to get the value-returning pcpu atomics working correctly when implemented using the LSE instructions.

Consequently, the VA_BITS definition cannot be used blindly, since it reflects only the size of kernel virtual addresses. This patch introduces MAX_USER_VA_BITS which is either VA_BITS or 52 depending on whether 52-bit virtual addressing has been configured at build time, removing a few places where the 52 is open-coded based on explicit CONFIG_ guards.

This allows to keep the PWM running if it was enabled in bootloader. It is very similar to the GPIO behavior. GPIO pin set as output in bootloader keep the same setting in Linux unless it is reconfigured. If we find the PWM block enabled we need to prepare and enable its source clock otherwise the clock will be disabled late in the boot as unused. That will leave the PWM in enabled state but with disabled clock. That has a side effect that the PWM output is left at its current level at which the clock was disabled. It is totally non-deterministic and it may be LOW or HIGH.

In case of the "remote event" infrastructure, my solution seemed significantly better, so I'm proposing this as a change on top. The problem with using either semaphores or completions here is that it's an overly complex way of waking up a thread, and it looks like the 'count' of the semaphore can easily get out of sync, even though I found it hard to come up with a specific example. Changing it to a 'wait_queue_head_t' instead of a completion simplifies this by letting us wait directly on the 'event->fired' variable that is set by the videocore. Another simplification is passing the wait queue directly into the helper functions instead of going through the fragile logic of recording the offset inside of a structure as part of a shared memory variable. This also avoids one uncached memory read and should be faster. Note that I'm changing it back to 'killable' after the previous patch changed 'killable' to 'interruptible', apparently based on a misunderstanding of the subtle down_interruptible() macro override in vchiq_killable.h.

This patch also changes these functions to only allocate as much memory as is necessary for each comedi_insn, rather than allocating a fixed-sized scratch space. In testing some user-space code for the new INSN_DEVICE_CONFIG_GET_ROUTES facility with some newer hardware, I discovered that do_insn_ioctl and do_insnlist_ioctl limited the amount of data that can be passed into the kernel for insn's to a length of 256. For some newer hardware, the number of routes can be greater than 1000. Working around the old limits (256) would complicate the user-space/kernel interaction. The new upper limit is reasonable with current memory available and does not otherwise impact the memory footprint for any current or otherwise typical configuration. Signed-off-by: Spencer E.

In Spectrum-2 this is no longer the case and the driver must interact directly with the policy engine in order to program multicast routes. Every route is written as an ACL rule, its priority set according to route type (*,G) or (S,G) and its action is an appropriate multicast routing action. Multicast routes are written to a specific ACL group which is bound to the appropriate IP protocol IPv4/IPv6. Patch #1 adds PEMRBT register needed to declare which ACL group is dedicated for each IP protocol multicast routing function. Patch #2 Changes initialization order and puts ACL before router as multicast router now uses ACL module. Patch #3 adds Spectrum-2 ACL keys needed for multicast route matching. Patch #4 adds another ACL profile - in addition to existing flower profile - which allows the multicast routing module to program rules directly into the ACL block. Patch #5 adds the ability to update ACL rules' action, since multicast routes actions may be updated after being configured. Patch #6 separates rule creation operation and rule action creation operation as in multicast router the action is created before the route is inserted. Patch #7 sharpens priority handling in Spectrum-2, to ensure incorrect values are not set to rule's priority. Patch #8 adds the implementation of multicast routing for IPv4 and IPv6 over existing ACL rule programming Finally, patch #9 adds a test for IPv4/IPv6 multicast routing. ==================== Signed-off-by: David S.

While it works for most, simple, PHYs supported so far, some more advanced PHYs need some configuration depending on runtime parameters. These PHYs have been supported by a number of means already, often by using ad-hoc drivers in their consumer drivers. That doesn't work too well however, when a consumer device needs to deal with multiple PHYs, or when multiple consumers need to deal with the same PHY (a DSI driver and a CSI driver for example). So we'll add a new interface, through two funtions, phy_validate and phy_configure. The first one will allow to check that a current configuration, for a given mode, is applicable. It will also allow the PHY driver to tune the settings given as parameters as it sees fit. phy_configure will actually apply that configuration in the phy itself.

The interface mode is selected by configuring the MII mode selection register(s) (GMII_SEL) in the System Control Module chapter (SCM). GMII_SEL register(s) and bit fields placement in SCM are different between SoCs while fields meaning is the same. Historically CPSW external Port's interface mode selection configuration was introduced using custom API and driver cpsw-phy-sel.c. This leads to unnecessary driver, DT binding and custom API support effort. This patch introduces CPSW Port's PHY Interface Mode selection Driver (phy-gmii-sel) which implements standard Linux PHY interface and used as a replacement for TI's specific driver cpsw-phy-sel.c and corresponding custom API.

This is because of the shared GPIO pins between mdm6600 USB port and n_gsm port. We have not enabled runtime PM for the phy driver until after we've booted up mdm6600 properly to the USB mode. Otherwise phy_create() would have called pm_runtime_enable() and pm_runtime_no_callbacks() automatically on init. Let's fix this by registering the phy a bit later after we've powered up the mdm6600 USB port. And as the PM runtime support is only needed for the n_gsm mode and not for USB, we can allow the device to idle between phy_mdm6600_power_on() and phy_mdm6600_power_off(). Note that for suspend, runtime_pm is already disabled for the phy so we need to check for pm_runtime_enabled().

The PHY has multiple lanes, which can be configured into groups, and a generic PHY device is created for each group. There are two resets controlling the overall PHY block, one to enable the APB interface for programming registers, and another to enable the PHY itself. Additionally there are resets for each PHY lane. The PHY can be configured in hardware to read register settings from ROM, or they can be written by the driver. The sequence of operation on startup is to enable the APB bus, write the PHY registers (if required) for each lane group, and then enable the PHY. Each group of lanes can then be individually controlled using the power_on()/ power_off() function for that generic PHY Signed-off-by: Alan Douglas Signed-off-by: Kishon Vijay Abraham I commit cb96a690724e105f149b27a88d66669c53b01625 Author: Alan Douglas Date: Mon Nov 12 16:42:01 2018 +0000 dt-bindings: phy: Document cadence Sierra PHY bindings Add DT binding documentation for Sierra PHY. The PHY supports a number of different protocols, including PCIe and USB. The PHY lanes may be configured as single or multi-lane links. Each link is treated as a separate sub-node. For example, if there are 4 lanes in total the first 2 might be configured as a multi-lane PCIe link while the other two are single lane USB links, and in this case there would be 3 sub-nodes. There are two resets for the PHY block (one for APB register access, one for the PHY link) and separate resets for each link. For multi-lane links, the reset corresponds to the reset line on the master lane, the resets on other lanes have no effect.

Both approaches are ineffective and would lead to fast bloating of enum phy_mode or struct phy_ops in the process of adding more PHYs for different subsystems which will make them unmaintainable. As discussed in [1] the solution could be to introduce dual level PHYs mode configuration - PHY mode and PHY submode. The PHY mode will define generic PHY type (subsystem - PCIE/ETHERNET/USB_) while the PHY submode - subsystem specific interface mode. The last is usually already defined in corresponding subsystem headers (phy_interface_t for Ethernet, enum usb_device_speed for USB). This patch is cumulative change which refactors PHY framework code to support dual level PHYs mode configuration - PHY mode and PHY submode. It extends .set_mode() callback to support additional parameter "int submode" and converts all corresponding PHY drivers to support new .set_mode() callback declaration. The new extended PHY API int phy_set_mode_ext(struct phy *phy, enum phy_mode mode, int submode) is introduced to support dual level PHYs mode configuration and existing phy_set_mode() API is converted to macros, so PHY framework consumers do not need to be changed (~21 matches).

The motivation for this is primarily for use with containers. For example, if a container does an init_module(), we obviously don't want to load this untrusted code, which may be compiled for the wrong version of the kernel anyway. Instead, we could parse the module image, figure out which module the container is trying to load and load it on the host. As another example, containers cannot mount() in general since various filesystems assume a trusted image. However, if an orchestrator knows that e.g. a particular block device has not been exposed to a container for writing, it want to allow the container to mount that block device (that is, handle the mount for it). This patch adds functionality that is already possible via at least two other means that I know about, both of which involve ptrace(): first, one could ptrace attach, and then iterate through syscalls via PTRACE_SYSCALL. Unfortunately this is slow, so a faster version would be to install a filter that does SECCOMP_RET_TRACE, which triggers a PTRACE_EVENT_SECCOMP. Since ptrace allows only one tracer, if the container runtime is that tracer, users inside the container (or outside) trying to debug it will not be able to use ptrace, which is annoying. It also means that older distributions based on Upstart cannot boot inside containers using ptrace, since upstart itself uses ptrace to monitor services while starting. The actual implementation of this is fairly small, although getting the synchronization right was/is slightly complex. Finally, it's worth noting that the classic seccomp TOCTOU of reading memory data from the task still applies here, but can be avoided with careful design of the userspace handler: if the userspace handler reads all of the task memory that is necessary before applying its security policy, the tracee's subsequent memory edits will not be read by the tracer.

Care needs to be taken when creating an ERR_PTR() from this value because a subsequent check using IS_ERR() expects the error to be within the MAX_ERRNO range. Using an invalid domain id as an ERR_PTR() does work at this time since this is currently always -1. Using this undocumented assumption is fragile since future users of rdt_find_domain() may not be aware of thus assumption. Two related issues are addressed: - Ensure that rdt_find_domain() always returns a valid error value by forcing the error to be -ENODEV when a negative domain id is provided. - In a few instances the return value of rdt_find_domain() is just checked for NULL - fix these to include a check of ERR_PTR.

This could be for one of two reasons: 1. If resolving supplies was happening before the call to set_machine_constraints() we needed to predict if set_machine_constraints() was going to turn the regulator on and we needed to preemptively turn the supply on. 2. Maybe set_machine_constraints() happened before we could resolve supplies (because we failed the first time to resolve) and thus we might need to propagate an enable that already happened up to our supply. Historically regulator_resolve_supply() used _regulator_is_enabled() to decide whether to turn on the supply. Let's change things a little bit. Specifically: 1. Let's try to enable the supply and the regulator in the same place, both in set_machine_constraints(). This means that we have exactly the same logic for enabling the supply and the regulator. 2. Let's properly set use_count when we enable always-on or boot-on regulators even for those that don't have supplies. The previous commit 1fc12b05895e ("regulator: core: Avoid propagating to supplies when possible") only did this right for regulators with supplies. 3. Let's make it clear that the only time we need to enable the supply in regulator_resolve_supply() is if the main regulator is currently in use. By using use_count (like the rest of the code) to decide if we're going to enable our supply we keep everything consistent. Overall the new scheme should be cleaner and easier to reason about. In addition to fixing regulator_summary to be more correct (because of the more correct use_count), this change also has the effect of no longer using _regulator_is_enabled() in this code path. _regulator_is_enabled() could return an error code for some regulators at bootup (like RPMh) that can't read their initial state. While one can argue that the design of those regulators is sub-optimal, the new logic sidesteps this brokenness. This fix in particular fixes observed problems on Qualcomm sdm845 boards which use the above-mentioned RPMh regulator. Those problems were made worse by commit 1fc12b05895e ("regulator: core: Avoid propagating to supplies when possible") because now we'd think at bootup that the SD regulators were already enabled and we'd never try them again.

Forcing RMX_ASPECT as default uses the preferred/native mode's timings for any mode the user selects and scales the image. This provides a a consistently nicer result in the case where the selected mode's refresh rate matches the native mode's refresh but this isn't always the case. For example, if the monitor is 1080p@144Hz and the preferred mode is 60Hz then even if the user selects 1080p@144Hz as their selected mode they'll get 1080p@60Hz.

Whilst the asm-offsets definition of TSK_TI_PREEMPT was updated to point to this new field, the assembly usage was left untouched meaning that a 32-bit load from TSK_TI_PREEMPT on a big-endian machine actually returns the reschedule flag instead of the count. Whilst we could fix this by pointing TSK_TI_PREEMPT at the count field, we're actually better off reworking the two assembly users so that they operate on the whole 64-bit value in favour of inspecting the thread flags separately in order to determine whether a reschedule is needed.

My assumption is that this does not happen during manual mode since the controller is stopping its work the moment it sets NA/ND bit in status register. This is not the case in Automatic/Sequentional mode where it is still working to send STOP condition and the actual status we get depends on the time when the ISR is run. This patch changes the order of checking status bits in ISR - error conditions are checked first and only if none of them occurred, the transfer may be considered successful.

This patch fix that issue by ensuring that pblk_dma_meta_size() always returns space equal to sizeof(struct pblk_sec_meta) and thus ppa list and meta list points to different memory address. Even that in that case drive does not really care about meta_list pointer, this is the easiest way to fix that issue without introducing changes in many places in the code just for 0 sized metadata case. The same approach needs to be also done for pblk_get_sec_meta() since we also cannot point to the same memory address in meta buffer when we are using it for pblk recovery process Reported-by: Hans Holmberg Tested-by: Hans Holmberg Signed-off-by: Igor Konopko Signed-off-by: Matias Bjørling Signed-off-by: Jens Axboe commit 55d8ec35398e7ab001989473cf6ed6f40b5ef4a6 Author: Igor Konopko Date: Tue Dec 11 20:16:26 2018 +0100 lightnvm: pblk: support packed metadata pblk performs recovery of open lines by storing the LBA in the per LBA metadata field. Recovery therefore only works for drives that has this field. This patch adds support for packed metadata, which store l2p mapping for open lines in last sector of every write unit and enables drives without per IO metadata to recover open lines. After this patch, drives with OOB size <16B will use packed metadata and metadata size larger than16B will continue to use the device per IO metadata.

The contents of each entry allocated from the DMA pool consists of a PPA list (8bytes * 64), leaving 56bytes * 64 space for metadata. Since the metadata field can be bigger, such as 128 bytes, the static size does not cover this use-case.

That allows us to just toggle the encoder's vblank interrupts on vblank_enable. So why is this important? Previously the driver was using the legacy pointers to assign/clear the crtc. Legacy pointers are cleared _after_ disabling the hardware, so the legacy pointer was valid during vblank_disable, but that's not something we should rely on. Instead of relying on the core ordering the legacy pointer assignments just so, we'll assign the crtc in dpu_crtc enable/disable. This is the only place that mapping can change, so we're covered there. We're also taking advantage of drm_crtc_vblank_on/off. By using this, we ensure that vblank_enable/disable can never be called while the crtc is off (which means the assigned crtc will always be valid). As such, we don't need to use modeset locks or the crtc_lock in the vblank_enable/disable routine to be sure state is consistent. ...I think.

It looks like the msm code adds all nodes to its list of components even if they are disabled. I believe this doesn't work because all registered components need to come up before we finish probing. Let's do like other DRM code and only add available components.

This is certainly not desirable and does not scale well with large captures. This patch encodes the buffer only once in the read path.

It is important to note that msm_gem_unpin_iova replaces msm_gem_put_iova because the new implicit behavior that an assigned iova in a given vma is now valid for the life of the buffer and what we are really focusing on is the use of that iova. For now the unmappings are lazy; once the reference counts go to zero they *COULD* be unmapped dynamically but that will require an outside force such as a shrinker or mm_notifiers.

The selection of an energy-efficient CPU for a task is achieved by estimating the impact on system-level active energy resulting from the placement of the task on the CPU with the highest spare capacity in each performance domain. This strategy spreads tasks in a performance domain and avoids overly aggressive task packing. The best CPU energy-wise is then selected if it saves a large enough amount of energy with respect to prev_cpu. Although it has already shown significant benefits on some existing targets, this approach cannot scale to platforms with numerous CPUs. This is an attempt to do something useful as writing a fast heuristic that performs reasonably well on a broad spectrum of architectures isn't an easy task. As such, the scope of usability of the energy-aware wake-up path is restricted to systems with the SD_ASYM_CPUCAPACITY flag set, and where the EM isn't too complex.

That is, there are spare cycles available to shift tasks around based on their actual utilization to get a more energy-efficient task distribution without depriving any tasks. When above the tipping point task placement is done the traditional way based on load_avg, spreading the tasks across as many cpus as possible based on priority scaled load to preserve smp_nice. Below the tipping point we want to use util_avg instead. We need to define a criteria for when we make the switch. The util_avg for each cpu converges towards 100% regardless of how many additional tasks we may put on it. If we define over-utilized as: sum_{cpus}(rq.cfs.avg.util_avg) + margin > sum_{cpus}(rq.capacity) some individual cpus may be over-utilized running multiple tasks even when the above condition is false. That should be okay as long as we try to spread the tasks out to avoid per-cpu over-utilization as much as possible and if all tasks have the _same_ priority. If the latter isn't true, we have to consider priority to preserve smp_nice. For example, we could have n_cpus nice=-10 util_avg=55% tasks and n_cpus/2 nice=0 util_avg=60% tasks. Balancing based on util_avg we are likely to end up with nice=-10 tasks sharing cpus and nice=0 tasks getting their own as we 1.5*n_cpus tasks in total and 55%+55% is less over-utilized than 55%+60% for those cpus that have to be shared. The system utilization is only 85% of the system capacity, but we are breaking smp_nice. To be sure not to break smp_nice, we have defined over-utilization conservatively as when any cpu in the system is fully utilized at its highest frequency instead: cpu_rq(any).cfs.avg.util_avg + margin > cpu_rq(any).capacity IOW, as soon as one cpu is (nearly) 100% utilized, we switch to load_avg to factor in priority to preserve smp_nice. With this definition, we can skip periodic load-balance as no cpu has an always-running task when the system is not over-utilized. All tasks will be periodic and we can balance them at wake-up. This conservative condition does however mean that some scenarios that could benefit from energy-aware decisions even if one cpu is fully utilized would not get those benefits. For systems where some cpus might have reduced capacity on some cpus (RT-pressure and/or big.LITTLE), we want periodic load-balance checks as soon a just a single cpu is fully utilized as it might one of those with reduced capacity and in that case we want to migrate it.

When using a CPUFreq governor other than schedutil, the chances of this assumption being true are small, if any. When schedutil is being used, EAS' predictions are at least consistent with the frequency requests. Although those requests have no guarantees to be honored by the hardware, they should at least guide DVFS in the right direction and provide some hope in regards to the EAS model being accurate. To make sure EAS is only used in a sane configuration, create a strong dependency on schedutil being used. Since having sugov compiled-in does not provide that guarantee, make CPUFreq call a scheduler function on governor changes hence letting it rebuild the scheduling domains, check the governors of the online CPUs, and enable/disable EAS accordingly.

This is particularly true since the Energy Model only includes the active power costs of CPUs, hence not providing enough data to compare packing-vs-spreading strategies. As such, disable EAS on root domains where the SD_ASYM_CPUCAPACITY flag is not set. While at it, disable EAS on systems where the complexity of the Energy Model is too high since that could lead to unacceptable scheduling overhead. All in all, EAS can be used on a root domain if and only if: 1. an Energy Model is available; 2. the root domain has an asymmetric CPU capacity topology; 3. the complexity of the root domain's EM is low enough to keep scheduling overheads low.

This one, sd_asym_cpucapacity, points to the lowest level at which the SD_ASYM_CPUCAPACITY flag is set. While at it, rename the sd_asym shortcut to sd_asym_packing to avoid confusions. Generally speaking, the largest opportunity to save energy via scheduling comes from a smarter exploitation of heterogeneous platforms (i.e. big.LITTLE). Consequently, the sd_asym_cpucapacity shortcut will be used at first as the lowest domain where Energy-Aware Scheduling (EAS) should be applied. For example, it is possible to apply EAS within a socket on a multi-socket system, as long as each socket has an asymmetric topology. Energy-aware cross-sockets wake-up balancing will only happen when the system is over-utilized, or this_cpu and prev_cpu are in different sockets.

However, Energy Aware Scheduling (EAS) requires more knowledge about the platform, and specifically needs to know about the span of Performance Domains (PD), which do not always align with caches. To address this issue, use the Energy Model (EM) of the system to extend the scheduler topology code with a representation of the PDs, alongside the scheduling domains. More specifically, a linked list of PDs is attached to each root domain. When multiple root domains are in use, each list contains only the PDs covering the CPUs of its root domain. If a PD spans over CPUs of multiple different root domains, it will be duplicated in all lists. The lists are fully maintained by the scheduler from partition_sched_domains() in order to cope with hotplug and cpuset changes. As for scheduling domains, the list are protected by RCU to ensure safe concurrent updates.

Yet, this information can come from different sources (DT or firmware for example), in different formats, hence making it hard to exploit without a standard API. As an attempt to address this, introduce a centralized Energy Model (EM) management framework which aggregates the power values provided by drivers into a table for each performance domain in the system. The power cost tables are made available to interested clients (e.g. task scheduler or thermal) via platform-agnostic APIs. The overall design is represented by the diagram below (focused on Arm-related drivers as an example, but applicable to any architecture): +---------------+ +-----------------+ +-------------+ | Thermal (IPA) | | Scheduler (EAS) | | Other | +---------------+ +-----------------+ +-------------+ | | em_pd_energy() | | | em_cpu_get() | +-----------+ | +--------+ | | | v v v +---------------------+ | | | Energy Model | | | | Framework | | | +---------------------+ ^ ^ ^ | | | em_register_perf_domain() +----------+ | +---------+ | | | +---------------+ +---------------+ +--------------+ | cpufreq-dt | | arm_scmi | | Other | +---------------+ +---------------+ +--------------+ ^ ^ ^ | | | +--------------+ +---------------+ +--------------+ | Device Tree | | Firmware | | ? | +--------------+ +---------------+ +--------------+ Drivers (typically, but not limited to, CPUFreq drivers) can register data in the EM framework using the em_register_perf_domain() API. The calling driver must provide a callback function with a standardized signature that will be used by the EM framework to build the power cost tables of the performance domain. This design should offer a lot of flexibility to calling drivers which are free of reading information from any location and to use any technique to compute power costs. Moreover, the capacity states registered by drivers in the EM framework are not required to match real performance states of the target. This is particularly important on targets where the performance states are not known by the OS. The power cost coefficients managed by the EM framework are specified in milli-watts. Although the two potential users of those coefficients (IPA and EAS) only need relative correctness, IPA specifically needs to compare the power of CPUs with the power of other components (GPUs, for example), which are still expressed in absolute terms in their respective subsystems. Hence, specifying the power of CPUs in milli-watts should help transitioning IPA to using the EM framework without introducing new problems by keeping units comparable across sub-systems. On the longer term, the EM of other devices than CPUs could also be managed by the EM framework, which would enable to remove the absolute unit. However, this is not absolutely required as a first step, so this extension of the EM framework is left for later. On the client side, the EM framework offers APIs to access the power cost tables of a CPU (em_cpu_get()), and to estimate the energy consumed by the CPUs of a performance domain (em_pd_energy()). Clients such as the task scheduler can then use these APIs to access the shared data structures holding the Energy Model of CPUs.

Since Energy Aware Scheduling (EAS) needs to be able to predict the frequency requests, it needs to forecast the decisions made by the governor. In order to prepare the introduction of EAS, introduce schedutil_freq_util() to centralize the aforementioned signal aggregation and make it available to both schedutil and EAS. Since frequency selection and energy estimation still need to deal with RT and DL signals slightly differently, schedutil_freq_util() is called with a different 'type' parameter in those two contexts, and returns an aggregated utilization signal accordingly. While at it, introduce the map_util_freq() function which is designed to make schedutil's 25% margin usable easily for both sugov and EAS. As EAS will be able to predict schedutil's frequency requests more accurately than any other governor by design, it'd be sensible to make sure EAS cannot be used without schedutil. This will be done later, once EAS has actually been introduced.

This line disappeared in final version but the comment has stayed." So remove the comment. Vincent also points out that the full ordering associated to the atomic_fetch_andnot() primitive could be relaxed, but this patch insists on the current more conservative/fully ordered solution: "Performance" isn't a concern, stay away from "correctness"/subtle relaxed (re)ordering if possible..., just make sure not to confuse the next reader with misleading/out-of-date comments.

In that regard, the current behaviour of creating them one-by-one leads to a lot of unwarranted function call overhead and memory wasted on alignment padding. Now that we don't have to worry about freeing anything via dma_debug_resize_entries(), we can optimise the allocation behaviour by grabbing whole pages at once, which will save considerably on the aforementioned overheads, and probably offer a little more cache/TLB locality benefit for traversing the lists under normal operation. This should also give even less reason for an architecture-level override of the preallocation size, so make the definition unconditional - if there is still any desire to change the compile-time value for some platforms it would be better off as a Kconfig option anyway. Since freeing a whole page of entries at once becomes enough of a challenge that it's not really worth complicating dma_debug_init(), we may as well tweak the preallocation behaviour such that as long as we manage to allocate *some* pages, we can leave debugging enabled on a best-effort basis rather than otherwise wasting them.

This does lose it the ability to save a couple of megabytes of RAM by reducing the pool size below its default, but it seems unlikely that that is a realistic concern these days (or indeed that anyone is actively debugging AGP drivers' DMA usage any more). Getting rid of dma_debug_resize_entries() will make room for further streamlining in the dma-debug code itself. Removing the call reveals quite a lot of cruft which has been useless for nearly a decade since commit 19c1a6f5764d ("x86 gart: reimplement IOMMU_LEAK feature by using DMA_API_DEBUG"), including the entire 'iommu=leak' parameter, which controlled nothing except whether dma_debug_resize_entries() was called or not.

To that end, let's inform the user each time the pool has grown to a multiple of its initial size, which should make it apparent that they either have a leak or might want to increase the preallocation size.

Developers trying to debug some other driver on such a system may not be immediately aware of this, and at worst it can hide bugs if they fail to realise that dma-debug has already disabled itself unexpectedly by the time their code of interest gets to run. Even once they do realise, it can be a bit of a pain to emprirically determine a suitable number of preallocated entries to configure, short of massively over-allocating. There's really no need for such a static limit, though, since we can quite easily expand the pool at runtime in those rare cases that the preallocated entries are insufficient, which is arguably the least surprising and most useful behaviour. To that end, refactor the prealloc_memory() logic a little bit to generalise it for runtime reallocations as well.

We have two issues in the queue count calculations: 1) We don't separate the poll queues from the read/write queues. This is important, since the former doesn't need interrupts. 2) The adjust logic is broken. Adjust the poll queue count before doing nvme_calc_io_queues(). The poll queue count is only limited by the IO queue count we were able to get from the controller, not failures in the IRQ allocation loop. This leaves nvme_calc_io_queues() just adjusting the read/write queue map.

Neither of these methods verify the kexec'ed kernel image signature being loaded via the kexec_load syscall. Secure boot enabled systems require kexec images to be signed. Therefore, this patch loads an IMA KEXEC_KERNEL_CHECK policy rule on secure boot enabled systems not configured with CONFIG_KEXEC_VERIFY_SIG enabled. When IMA_APPRAISE_BOOTPARAM is configured, different IMA appraise modes (eg. fix, log) can be specified on the boot command line, allowing unsigned or invalidly signed kernel images to be kexec'ed.

There is a need for yet another type of policy, an architecture specific policy, which is derived at runtime during kernel boot, based on the runtime secure boot flags.

That happens when the OPP core isn't managing the regulators for the device and the device's OPP do have microvolt property. It happens because the opp_table->regulator_count remains set to 0 and the debugfs routines don't add any supply directory in such a case. This commit fixes that by setting opp_table->regulator_count to 1 in that particular case. But to make everything work nicely and not break other parts of the core, regulator_count is defined as "int" now instead of "unsigned int" and it can have different special values now. It is set to -1 initially to mark it "uninitialized" and later only we set it to 0 or positive values after checking how many supplies are there. This also helps in finding the bugs where only few of the OPPs have the "opp-microvolt" property set and not all.

The motivation for this change is to have a policy for page allocation consistent with direct DMA mapping, which attempts to allocate pages local to the device, as mentioned in [1].

This patch is a big surgery for addressing the complexity and the possible unbalance. Basically the patch changes the display PM in the following ways: - Both HD-audio controller and codec drivers call a single helper, snd_hdac_display_power(). (Formerly, the display power control from a codec was done indirectly via link_power bus ops.) - snd_hdac_display_power() receives the codec address index. For turning on/off from the controller, pass HDA_CODEC_IDX_CONTROLLER. - snd_hdac_display_power() doesn't manage refcounts any longer, but keeps the power status in bitmap. If any of controller or codecs is turned on, the function updates the DRM power state via get_power() or put_power(). Also this refactor allows us more cleanup: - The link_power bus ops is dropped, so there is no longer indirect management, as mentioned in the above. - hdac_device link_power_control flag is moved to hda_codec display_power_control flag, as it's only for HDA legacy.

This fix is relevant for the same new systems MQMB7, MSN37, MSN34, which are about to be released to the customers. At the moment, none of them is at customers sites. The customers will not suffer from this change. This fix is necessary, because register used before for tachometer 7 has been than reserved for the second PWM for newer systems, which are not supported yet in mlx-platform driver. So registers of tachometers 7-12 have been shifted by one.

If the property is missing polarity isn't changed and so the polarity is kept as setup by the bootloader. Reset default is active high, so active low can only be used with help by the bootloader. On i.MX7 it is similar, but there disabling of over current detection has a similar inconsistency. This patch introduces a new property that allows to explicitly configure for active low over current detection and consistently sets this up. In the absence of an explicit configuration the bit is kept as is. On i.MX7 over current detection is used unless disabled in the device tree.

Fix the md_in_flight() check to sum all counters before returning a false positive, potentially. While at it, remove the inflight read for IO completion. We don't need it, just wake anyone that's waiting for the IO count to drop to zero. The caller needs to re-check that value anyway when woken, which it does.

The original intention is to keep the field names the same as those in structure bpf_attr, so it will be clear that the "count" returned to user space will be the same as the one passed to the kernel during prog load. Unfortunately, the field names *_info_cnt are not consistent with other existing fields in bpf_prog_info.

This leaves us 2 options: 1/ set the SPI_NOR_SKIP_SFDP flag and completely ignore SFDP parsing 2/ fix things at runtime While #1 should always work, it might imply extra work if most of the SFDP is correct. #2 has the benefit of keeping the generic SFDP parsing logic almost untouched while allowing SPI NOR manufacturer drivers to fix the broken bits. Add a spi_nor_fixups struct where we'll put all our fixup hooks, each of them being called at a different point in the scan process. We start a hook called just after the BFPT parsing to allow fixing up info extracted from the BFPT section. More hooks will be added if other sections need to be fixed.

The hardware setup looks something like this: _ refclk-o---PLL---o----DIV1-----| \ | | |M |----OUT1 o-----------------------|_/ | | _ | o----DIV2-----| \ | | |M |----OUT2 o-----------------------|_/ | | _ | `----DIV3-----| \ | |M |----OUT3 `-----------------------|_/ The bypass bit not only bypasses the PLL, but also the attached post-dividers. This would be reasonbly straight forward to model with a single output, or with different bypass bits for each output, but sadly the HW guys decided that it would be good to actuate all 3 muxes with a single bit. So the need to have the PLL bypassed for one of the outputs always affects 2 other (in our model) independent branches of the clock tree. This means the decision to bypass this PLL is a system wide design choice and should not be changed on-the-fly, so we can treat any bapass configuration as static. As such we can just register the post-dividiers with a ratio that reflects the bypass status, which allows us to bypass the PLL without breaking our abstraction model and with it DT stability.

This is in line with how drivers of the later CCM driver revisions on newer i.MX SoCs handle this.

To exploit this one has to be running with a 64KB page size and be running on hardware that supports this. For an arm64 kernel supporting a 48 bit VA with a 64KB page size, some changes are needed to support a 52-bit userspace: * TCR_EL1.T0SZ needs to be 12 instead of 16, * TASK_SIZE needs to reflect the new size. This patch implements the above when the support for 52-bit VAs is detected at early boot time. On arm64 userspace addresses translation is controlled by TTBR0_EL1. As well as userspace, TTBR0_EL1 controls: * The identity mapping, * EFI runtime code. It is possible to run a kernel with an identity mapping that has a larger VA size than userspace (and for this case __cpu_set_tcr_t0sz() would set TCR_EL1.T0SZ as appropriate). However, when the conditions for 52-bit userspace are met; it is possible to keep TCR_EL1.T0SZ fixed at 12. Thus in this patch, the TCR_EL1.T0SZ size changing logic is disabled.

This patch adds code to the secondary startup path. If the boot CPU has enabled 52-bit VAs then ID_AA64MMFR2_EL1 is checked to see if the secondary can also enable 52-bit support. If not, the secondary is prevented from booting and an error message is displayed indicating why. Technically this patch could be implemented using the cpufeature code when considering 52-bit userspace support. However, we employ low level checks here as the cpufeature code won't be able to run if we have mismatched 52-bit kernel va support.

This quantity, PTRS_PER_PGD is used as follows to compute which PGD entry corresponds to a given virtual address, addr: pgd_index(addr) -> (addr >> PGDIR_SHIFT) & (PTRS_PER_PGD - 1) Userspace addresses are prefixed by 0's, so for a 48-bit userspace address, uva, the following is true: (uva >> PGDIR_SHIFT) & (1024 - 1) == (uva >> PGDIR_SHIFT) & (64 - 1) In other words, a 48-bit userspace address will have the same pgd_index when using PTRS_PER_PGD = 64 and 1024. Kernel addresses are prefixed by 1's so, given a 48-bit kernel address, kva, we have the following inequality: (kva >> PGDIR_SHIFT) & (1024 - 1) != (kva >> PGDIR_SHIFT) & (64 - 1) In other words a 48-bit kernel virtual address will have a different pgd_index when using PTRS_PER_PGD = 64 and 1024. If, however, we note that: kva = 0xFFFF << 48 + lower (where lower[63:48] == 0b) and, PGDIR_SHIFT = 42 (as we are dealing with 64KB PAGE_SIZE) We can consider: (kva >> PGDIR_SHIFT) & (1024 - 1) - (kva >> PGDIR_SHIFT) & (64 - 1) = (0xFFFF << 6) & 0x3FF - (0xFFFF << 6) & 0x3F // "lower" cancels out = 0x3C0 In other words, one can switch PTRS_PER_PGD to the 52-bit value globally provided that they increment ttbr1_el1 by 0x3C0 * 8 = 0x1E00 bytes when running with 48-bit kernel VAs (TCR_EL1.T1SZ = 16). For kernel configuration where 52-bit userspace VAs are possible, this patch offsets ttbr1_el1 and sets PTRS_PER_PGD corresponding to the 52-bit value.

In order to achieve this, on 52-bit VA systems, we make mmap behave as if it were running on a 48-bit VA system (unless userspace explicitly requests a VA where addr[51:48] != 0). On a system running a 52-bit userspace we need TASK_SIZE to represent the 52-bit limit as it is used in various places to distinguish between kernelspace and userspace addresses. Thus we need a new limit for mmap, stack, ELF loader and EFI (which uses TTBR0) to represent the non-extended VA space.

As a result, it can trigger a stack overrun quite often with 32k stack size compiled using GCC 8. For example, this reproducer https://github.com/linux-test-project/ltp/blob/master/testcases/kernel/syscalls/madvise/madvise06.c can trigger a "corrupted stack end detected inside scheduler" very reliably with CONFIG_SCHED_STACK_END_CHECK enabled.

This is too conservative that some valid cases will be rejected. Especially, this may turn a constant scalar value into unknown value that could break some assumptions of verifier. For example, test_l4lb_noinline.c has the following C code: struct real_definition *dst 1: if (!get_packet_dst(&dst, &pckt, vip_info, is_ipv6)) 2: return TC_ACT_SHOT; 3: 4: if (dst->flags & F_IPV6) { get_packet_dst is responsible for initializing "dst" into valid pointer and return true (1), otherwise return false (0). The compiled instruction sequence using alu32 will be: 412: (54) (u32) r7 &= (u32) 1 413: (bc) (u32) r0 = (u32) r7 414: (95) exit insn 413, a BPF_MOV | BPF_ALU, however will turn r0 into unknown value even r7 contains SCALAR_VALUE 1. This causes trouble when verifier is walking the code path that hasn't initialized "dst" inside get_packet_dst, for which case 0 is returned and we would then expect verifier concluding line 1 in the above C code pass the "if" check, therefore would skip fall through path starting at line 4. Now, because r0 returned from callee has became unknown value, so verifier won't skip analyzing path starting at line 4 and "dst->flags" requires dereferencing the pointer "dst" which actually hasn't be initialized for this path. This patch relaxed the code marking sub-register move destination. For a SCALAR_VALUE, it is safe to just copy the value from source then truncate it into 32-bit. A unit test also included to demonstrate this issue. This test will fail before this patch. This relaxation could let verifier skipping more paths for conditional comparison against immediate. It also let verifier recording a more accurate/strict value for one register at one state, if this state end up with going through exit without rejection and it is used for state comparison later, then it is possible an inaccurate/permissive value is better. So the real impact on verifier processed insn number is complex. But in all, without this fix, valid program could be rejected. >From real benchmarking on kernel selftests and Cilium bpf tests, there is no impact on processed instruction number when tests ares compiled with default compilation options. There is slightly improvements when they are compiled with -mattr=+alu32 after this patch. Also, test_xdp_noinline/-mattr=+alu32 now passed verification. It is rejected before this fix. Insn processed before/after this patch: default -mattr=+alu32 Kernel selftest === test_xdp.o 371/371 369/369 test_l4lb.o 6345/6345 5623/5623 test_xdp_noinline.o 2971/2971 rejected/2727 test_tcp_estates.o 429/429 430/430 Cilium bpf === bpf_lb-DLB_L3.o: 2085/2085 1685/1687 bpf_lb-DLB_L4.o: 2287/2287 1986/1982 bpf_lb-DUNKNOWN.o: 690/690 622/622 bpf_lxc.o: 95033/95033 N/A bpf_netdev.o: 7245/7245 N/A bpf_overlay.o: 2898/2898 3085/2947 NOTE: - bpf_lxc.o and bpf_netdev.o compiled by -mattr=+alu32 are rejected by verifier due to another issue inside verifier on supporting alu32 binary. - Each cilium bpf program could generate several processed insn number, above number is sum of them. v1->v2: - Restrict the change on SCALAR_VALUE. - Update benchmark numbers on Cilium bpf tests.

This is because all the debug options enabled causes the loop in ftrace_replace_code() (which loops over all the functions being enabled where there can be 10s of thousands), is too slow, and never schedules out. To solve this, setting FTRACE_MAY_SLEEP to the command passed into ftrace_replace_code() will make it call cond_resched() in the loop, which prevents the soft lockup warning from triggering.

If the I/Os take less than a jiffy, the value is as exact as the previously calculated value. If the I/Os take more than a jiffy, io_ticks can drift behind the previously calculated value.

As a result, we end up with some undefined symbols in cache.o: $ nm arch/arm64/mm/cache.o ... U civac ... U cvac U cvap U cvau This is due to the fact that the comparisons used to select the operation type in the dcache_by_line_op macro are comparing symbols not strings, and even though it seems that GAS is doing the right thing here (undefined symbols by the same name are equal to each other), it seems unwise to rely on this. Second, when patching in a DC CVAP instruction on CPUs that support it, the fallback path consists of a DC CVAU instruction which may be affected by CPU errata that require ARM64_WORKAROUND_CLEAN_CACHE. Solve these issues by unrolling the various maintenance routines and using the conditional directives that are documented as operating on strings. To avoid the complexity of nested alternatives, we move the DC CVAP patching to __clean_dcache_area_pop, falling back to a branch to __clean_dcache_area_poc if DCPOP is not supported by the CPU.

The device_link feature helps to track such functional dependencies, so that the iommu gets powered when the master device enables itself using pm_runtime. So by adapting the smmu driver for runtime pm, above said dependency can be addressed. This patch adds the pm runtime/sleep callbacks to the driver and the corresponding bulk clock handling for all the clocks needed by smmu. Also, while we enable the runtime pm, add a pm sleep suspend callback that pushes devices to low power state by turning the clocks off in a system sleep. Add corresponding clock enable path in resume callback as well.

A memory barrier is required here so that all reads targetting the queue entry have completed before the consumer pointer is updated. The implementation of queue_inc_cons() relies on a writel() to complete the previous reads, but this is incorrect because writel() is only guaranteed to complete prior writes. This patch replaces the call to writel() with an mb(); writel_relaxed() sequence, which gives us the read->write ordering which we require.

However, when delivering MSIs to memory, as we do in the SMMUv3 driver for signalling the completion of a SYNC command, the extended payload will corrupt the 4 bytes adjacent to the "sync_count" member in struct arm_smmu_device. Fortunately, the current layout allocates these bytes to padding, but this is fragile and we should make this explicit.

Thus on big-endian systems, the SMMU will receive and write back a byteswapped version of sync_nr, which would be perfect if it were targeting a similarly-little-endian ITS, but since it's actually writing back to memory being polled by the CPUs, they're going to end up seeing the wrong thing. Since the SMMU doesn't care what the MSIData actually contains, the minimal-overhead solution is to simply add an extra byteswap initially, such that it then writes back the big-endian format directly.

To make it easy by keeping a script and which will generate the uapi header and syscall table file. This change will also help to unify the implemen- tation across all architectures. The system call table generation script is added in kernel/syscalls directory which contain the scripts to generate both uapi header file and system call table files. The syscall.tbl will be input for the scripts. syscall.tbl contains the list of available system calls along with system call number and corresponding entry point. Add a new system call in this architecture will be possible by adding new entry in the syscall.tbl file. Adding a new table entry consisting of: - System call number. - ABI. - System call name. - Entry point name. - Compat entry name, if required. syscallhdr.sh and syscalltbl.sh will generate uapi header unistd_32/64.h and syscall_table_32/64/c32.h files respect- ively. Both .sh files will parse the content syscall.tbl to generate the header and table files. unistd_32/64.h will be included by uapi/asm/unistd.h and syscall_table_32/64/- c32.h is included by kernel/syscall.S - the real system call table. ARM, s390 and x86 architecuture does have similar support. I leverage their implementation to come up with a generic solution.

We have to change the value of __NR_Linux_syscalls, if we add or delete a system call. One of the patch in this patch series has a script which will generate a uapi header based on syscall.tbl file. The syscall.tbl file contains the total number of system calls information. So we have two option to update __NR- _Linux_syscalls value. 1. Update __NR_Linux_syscalls in asm/unistd.h manually by counting the no.of system calls. No need to update __NR- _Linux_syscalls until we either add a new system call or delete existing system call. 2. We can keep this feature it above mentioned script, that will count the number of syscalls and keep it in a generated file. In this case we don't need to expli- citly update __NR_Linux_syscalls in asm/unistd.h file. The 2nd option will be the recommended one. For that, I added the __NR_syscalls macro in uapi/asm/unistd.h along with __NR_Linux_syscalls asm/unistd.h. The macro __NR_sys- calls also added for making the name convention same across all architecture. While __NR_syscalls isn't strictly part of the uapi, having it as part of the generated header to simplifies the implementation. We also need to enclose this macro with #ifdef __KERNEL__ to avoid side effects.

It is correct to keep __IGNORE* entry in non uapi header asm/unistd.h while uapi/asm/unistd.h must hold information only useful for user space applications. One of the patch in this patch series will generate uapi header file. The information which directly used by the user space application must be present in uapi file.

This fixes a problem on various Amlogic Meson SoCs where USB devices are only recognized when plugged in before booting Linux. A hot-plugged USB device was not detected even though the device got power (my USB thumb drive for example has an LED which lit up). A similar fix was implemented for Rockchip SoCs in commit c216765d3a1def ("usb: dwc2: disable power_down on rockchip devices"). That commit suggests that a change in the dwc2 driver is the cause because the default value for the "hibernate" parameter (which then got renamed to "power_down" to support other modes) was changed in the v4.17 merge window with: commit 6d23ee9caa6790 ("Merge tag 'usb-for-v4.17' of git://git.kernel.org/pub/scm/linux/kernel/git/balbi/usb into usb-testing").

Miller Date: Sun Dec 9 21:27:48 2018 -0800 Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net Several conflicts, seemingly all over the place. I used Stephen Rothwell's sample resolutions for many of these, if not just to double check my own work, so definitely the credit largely goes to him. The NFP conflict consisted of a bug fix (moving operations past the rhashtable operation) while chaning the initial argument in the function call in the moved code. The net/dsa/master.c conflict had to do with a bug fix intermixing of making dsa_master_set_mtu() static with the fixing of the tagging attribute location. cls_flower had a conflict because the dup reject fix from Or overlapped with the addition of port range classifiction. __set_phy_supported()'s conflict was relatively easy to resolve because Andrew fixed it in both trees, so it was just a matter of taking the net-next copy. Or at least I think it was :-) Joe Stringer's fix to the handling of netns id 0 in bpf_sk_lookup() intermixed with changes on how the sdif and caller_net are calculated in these code paths in net-next. The remaining BPF conflicts were largely about the addition of the __bpf_md_ptr stuff in 'net' overlapping with adjustments and additions to the relevant data structure where the MD pointer macros are used.

The EVK enables HDMI output for simple out-of-the-box to bring up but allows reconfiguration for MIPI displays. The EVK is designed as a System-On-Module(SOM) board that connects to an associated baseboard. The SOM provides 1 GB LPDDR3, 8 MB Quad SPI flash, Micro SD 3.0 card socket, WiFi/ Bluetooth capability, USB 2.0 OTG with Type C connector and an NXP PF1550 power management IC (PMIC). The baseboard provides additional capabilities including a full SD/MMC 3.0 card socket, audio codec, multiple sensors, an HDMI connector, and an alternate MIPI display connector. Additionally, the EVK facilitates software development with the ultimate goal of faster time to market through the support of both Linux OS and AndroidTM rich operating systems, as well as FreeRTOS.

Dong Date: Sat Nov 10 15:13:04 2018 +0000 ARM: imx: add initial support for imx7ulp The i.MX 7ULP family of processors features NXP's advanced implementation of the Arm Cortex-A7 core, the Arm Cortex-M4 core, as well as a 3D and 2D Graphics Processing Units (GPUs). This patch aims to add an initial support for imx7ulp. Note that we need configure power mode to Partial Stop mode 3 with system/bus clock enabled first as the default enabled STOP mode will gate off system/bus clock when execute WFI in MX7ULP SoC. And there's still no MXC_CPU_IMX7ULP IDs read from register as ULP has no anatop as before. So we encode one with 0xff in reverse order in case new ones will be in the future.

What this essentially says is that the sbitmap swap_lock was used inconsistently in IRQ enabled and disabled context, and that is usually indicative of a bug that will cause a deadlock. For this case, it's a false positive. The swap_lock is used from process context only, when we swap the bits in the word and cleared mask. We also end up doing that when we are getting a driver tag, from the blk_mq_mark_tag_wait(), and from there we hold the waitqueue lock with IRQs disabled. However, this isn't from an actual IRQ, it's still process context. In lieu of a better way to fix this, simply always disable interrupts when grabbing the swap_lock if lockdep is enabled.

If the main prog *_info relocation fails, it will ignore the remaining subprog line_info and continue. If the subprog *_info relocation fails, it will bail out. 3) BPF_PROG_LOAD a prog with line_info Signed-off-by: Martin KaFai Lau Acked-by: Yonghong Song Signed-off-by: Alexei Starovoitov commit f0187f0b17fad7439f510eff4d65606c9ea1190f Author: Martin KaFai Lau Date: Fri Dec 7 16:42:29 2018 -0800 bpf: libbpf: Refactor and bug fix on the bpf_func_info loading logic This patch refactor and fix a bug in the libbpf's bpf_func_info loading logic. The bug fix and refactoring are targeting the same commit 2993e0515bb4 ("tools/bpf: add support to read .BTF.ext sections") which is in the bpf-next branch. 1) In bpf_load_program_xattr(), it should retry when errno == E2BIG regardless of log_buf and log_buf_sz. This patch fixes it. 2) btf_ext__reloc_init() and btf_ext__reloc() are essentially the same except btf_ext__reloc_init() always has insns_cnt == 0. Hence, btf_ext__reloc_init() is removed. btf_ext__reloc() is also renamed to btf_ext__reloc_func_info() to get ready for the line_info support in the next patch. 3) Consolidate func_info section logic from "btf_ext_parse_hdr()", "btf_ext_validate_func_info()" and "btf_ext__new()" to a new function "btf_ext_copy_func_info()" such that similar logic can be reused by the later libbpf's line_info patch. 4) The next line_info patch will store line_info_cnt instead of line_info_len in the bpf_program because the kernel is taking line_info_cnt also. It will save a few "len" to "cnt" conversions and will also save some function args. Hence, this patch also makes bpf_program to store func_info_cnt instead of func_info_len. 5) btf_ext depends on btf. e.g. the func_info's type_id in ".BTF.ext" is not useful when ".BTF" is absent. This patch only init the obj->btf_ext pointer after it has successfully init the obj->btf pointer. This can avoid always checking "obj->btf && obj->btf_ext" together for accessing ".BTF.ext". Checking "obj->btf_ext" alone will do. 6) Move "struct btf_sec_func_info" from btf.h to btf.c. There is no external usage outside btf.c.

It is replaced with a direct syscall(__NR_bpf, BPF_PROG_LOAD,...). 2) The test_func_type() is renamed to test_info_raw() to prepare for the new line_info test in the next patch. 3) The bpf_obj_get_info_by_fd() testing for func_info is refactored to test_get_finfo(). A new test_get_linfo() will be added in the next patch for testing line_info purpose. 4) The test->func_info_cnt is checked instead of a static value "2". 5) Remove unnecessary "\n" in error message. 6) Adding back info_raw_test_num to the cmd arg such that a specific test case can be tested, like all other existing tests. 7) Fix a bug in handling expected_prog_load_failure. A test could pass even if prog_fd != -1 while expected_prog_load_failure is true. 8) The min rec_size check should be < 8 instead of < 4.

It accepts an array of bpf_line_info objects during BPF_PROG_LOAD. The "line_info", "line_info_cnt" and "line_info_rec_size" are added to the "union bpf_attr". The "line_info_rec_size" makes bpf_line_info extensible in the future. The new "check_btf_line()" ensures the userspace line_info is valid for the kernel to use. When the verifier is translating/patching the bpf_prog (through "bpf_patch_insn_single()"), the line_infos' insn_off is also adjusted by the newly added "bpf_adj_linfo()". If the bpf_prog is jited, this patch also provides the jited addrs (in aux->jited_linfo) for the corresponding line_info.insn_off. "bpf_prog_fill_jited_linfo()" is added to fill the aux->jited_linfo. It is currently called by the x86 jit. Other jits can also use "bpf_prog_fill_jited_linfo()" and it will be done in the followup patches. In the future, if it deemed necessary, a particular jit could also provide its own "bpf_prog_fill_jited_linfo()" implementation. A few "*line_info*" fields are added to the bpf_prog_info such that the user can get the xlated line_info back (i.e. the line_info with its insn_off reflecting the translated prog). The jited_line_info is available if the prog is jited. It is an array of __u64. If the prog is not jited, jited_line_info_cnt is 0. The verifier's verbose log with line_info will be done in a follow up patch.

When device tree is being used, the bus is not scanned for devices, only those devices which are in device tree are probed. Without device tree, by default, all addresses on the bus are scanned. This may then find a device which is not a PHY, e.g. a switch. And the switch may have registers containing values which look like a PHY. So during the scan, a PHY device is wrongly created. After the bus has been registered, a search is made for mdio_board_info structures which indicates devices on the bus, and the driver which should be used for them. This is typically used to instantiate Ethernet switches from platform drivers. However, if the scanning of the bus has created a PHY device at the same location as indicated into the board info for a switch, the switch device is not created, since the address is already busy. This can be avoided by setting the phy_mask of the mdio bus. This mask prevents addresses on the bus being scanned. v2 Reviewed-by: Florian Fainelli Signed-off-by: David S.

In that case, if we keep the synth_event_mutex locked while registering/unregistering synthetic events, its dependency will be inversed. To avoid this issue, current synthetic event is using a 2 phase process to create/delete events. For example, it searches existing events under synth_event_mutex to check for event-name conflicts, and unlocks synth_event_mutex, then registers a new event under event_mutex locked. Finally, it locks synth_event_mutex and tries to add the new event to the list. But it can introduce complexity and a chance for name conflicts. To solve this simpler, this introduces trace_add_event_call_nolock() and trace_remove_event_call_nolock() which don't acquire event_mutex inside. synthetic event can lock event_mutex before synth_event_mutex to solve the lock dependency issue simpler.

"From reviewing the code, it seems possible for stack_trace_max.nr_entries to be set to .max_entries and in that case we would be reading one element beyond the end of the stack_dump_trace[] array. If it's not set to .max_entries then the bug doesn't affect runtime." Although it looks to be the case, it is not. Because we have: static unsigned long stack_dump_trace[STACK_TRACE_ENTRIES+1] = { [0 ... (STACK_TRACE_ENTRIES)] = ULONG_MAX }; struct stack_trace stack_trace_max = { .max_entries = STACK_TRACE_ENTRIES - 1, .entries = &stack_dump_trace[0], }; And: stack_trace_max.nr_entries = x; for (; x < i; x++) stack_dump_trace[x] = ULONG_MAX; Even if nr_entries equals max_entries, indexing with it into the stack_dump_trace[] array will not overflow the array. But if it is the case, the second part of the conditional that tests stack_dump_trace[nr_entries] to ULONG_MAX will always be true. By applying Dan's patch, it removes the subtle aspect of it and makes the if conditional slightly more efficient.

This is similar to the way function hooks are enabled (it passes in ftrace_ops). Instead of passing in the functions to use, a single structure is passed in to the registering function. The unregister function is now passed in the fgraph_ops handle. When we allow more than one callback to the function graph hooks, this will let the system know which one to remove.

When the dac resolution was lower than the register size (ex. 12 bits out of 16 bits) the readback value was not shifted with the difference in bits and the value was higher. Also a mask is applied on the read value in order to get the value relative to the actual bit size.

The device has a built-in 2.5V reference which is enabled by default. Another important difference is that the SPI write command operation is 16 bits long. The first four bits represent the command, while the remaining 12 bits are for data. In the control reg, DB9 and DB10 are used for power-down modes, while DB8 is the REF bit. In order to accommodate this change, a new regmap type was defined and checked accordingly. Because AD5310R does not have a readback register, the read_raw operation will return "Operation is not supported".

In such states, an immediate command requeue is expected to fail. The driver may exceed its max retry count, which permanently ends the command in failure when the same command would succeed after waiting for the controller to be ready. NVMe ratified TP 4033 provides a delay hint in the completion status code for failed commands. Implement the retry delay based on the command completion status and the controller's requested delay. Note that requeued commands are handled per request_queue, not per individual request. If multiple commands fail, the controller should consistently report the desired delay time for retryable commands in all CQEs, otherwise the requeue list may be kicked too soon.

And only blk_mq_map_queues() may rebuild the mapping talbe. One case is that we limit .nr_hw_queues as 1 in case of kdump kernel. However, drivers often builds queue mapping before allocating tagset via pci_alloc_irq_vectors_affinity(), but set->nr_hw_queues can be set as 1 in case of kdump kernel, so wrong queue mapping is used, and kernel panic[1] is observed during booting. This patch fixes the kernel panic triggerd on nvme by rebulding the mapping table via blk_mq_map_queues().

The first part returns a blkcg where a reference is owned by the bio meaning it does not need to be rcu protected. However, the third case, the last line, is problematic: return css_to_blkcg(task_css(current, io_cgrp_id)); This can race against task migration and the cgroup dying. It is also semantically different as it must be called rcu protected and is susceptible to failure when trying to get a reference to it. This patch adds association ahead of calling bio_blkcg() rather than after. This makes association a required and explicit step along the code paths for calling bio_blkcg(). In blk-iolatency, association is moved above the bio_blkcg() call to ensure it will not return %NULL. BFQ uses the old bio_blkcg() function, but I do not want to address it in this series due to the complexity. I have created a private version documenting the inconsistency and noting not to use it.

As termination on the chip is not immediate, the chip may issue a dma request to the now unmapped dma buffer, resulting in a iommu fault. Change the driver to receive a confirmation that logging ahs been terminated. As the driver always issues an SLI reset with the device as part of shutdown, and as part of that is receiving confirmation that the reset is complete - the driver was modified to perform the write to disable fw logging prior to the SLI reset and only free the fw log buffer after the SLI reset is complete.

When point to point, an FLOGI is to be exchanged by the two ports, with the port with the most significant WWN then proceeding with PLOGI. The implementation in the driver was keyed to closely with "what have I sent", not with what has happened between the two endpoints. Thus, it blatantly would ACC an FLOGI, but reject PLOGI's until it had its FLOGI ACC'd. The problem is - the sending of FLOGI may be delayed for some reason, or the response to FLOGI held off by the other side. In the failing situation the other side sent an FLOGI, which was ACC'd, then sent PLOGIs which were then rjt'd until the retry count for the PLOGIs were exceeded and the port gave up. The FLOGI may have been very late in transmit, or the response held off until the PLOGIs failed. Given the other port had the higher WWN, no PLOGIs would occur and communication stopped. Correct the situation by changing the FLOGI handling. Defer any response to an FLOGI until the driver has sent its FLOGI as well. Then, upon either completion of the sent FLOGI, or upon sending an ACC to a received FLOGI (which may be received before or just after FLOGI was sent). the driver will act on who has the higher WWN. if the other port does, the driver will noop any handling of an FLOGI response (if outstanding) and wait for PLOGI. If the local port does, the driver will transition to sending PLOGI and will noop any action on responding to an FLOGI (if not yet received). Fortunately, to implement this, it only took another state flag and deferring any FLOGI response if the FLOGI has yet to be transmit. All subsequent actions were already in place.

The driver, when it sees a 2nd FLOGI without an intervening link bounce, automatically performs a link bounce. In this, the link bounce causes the situate to repeat and in a nasty loop of link bounces. Resolve the issue by validating the FLOGI payload. The erroneous FLOGI will contain VVL signatures that are not normal. When the driver sees these, it will simply reject the flogi rather than bouncing the link. The reject is consumed within the firmware. Signed-off-by: Dick Kennedy Signed-off-by: James Smart Signed-off-by: Martin K.

Two initiator ports were cable swapped and after swap both went down. The driver internally swaps the nlp nodes based on matching node wwn's but not the same nport id as before. After detecting a change in the nodes RPI, the driver sends an UNREG_RPI command and clears the NLP_RPI_REGISTERED flag, then swaps the node information with the other node. But the other node's NLP_RPI_REGISTERED flag is also cleared, but it is done so without an UNREG_RPI being sent, which causes the later REG_RPI for that other node to fail as the hardware believes its still registered. Additionally, if the node swap occurred while the two nodes had PLOGI's in flight, the fc4_types weren't properly getting swapped such that when the PLOGIs commpleted and PRLI's were then sent, the PRLI's acted on bad protocol types so the PRLI was for the wrong protocol. NVME devices saw SCSI FCP PRLIs and vice versa. Clean up the node swap so that the NLP_RPI_REGISTERED flag is handled properly.

Each of those RSCN's ends up generating UNREG_RPI and REG_PRI mailbox commands. The discovery engine within the driver doesn't wait for the mailbox command completions. Instead it sets state flags and moves forward. At some point, there's a massive backlog of mailbox commands which take time for the adapter to process. Additionally, it appears there were duplicate events from the switch so the driver generated duplicate mailbox commands for the same remote port. During this window, failures on PLOGI and PRLI ELS's are see as the adapter is rejecting them as they are for remote ports that still have pending mailbox commands. Streamline the discovery engine so that PLOGI log checks for outstanding UNREG_RPIs and defer the processing until the commands complete. This better synchronizes the ELS transmission vs the RPI registrations. Filter out multiple UNREG_RPIs being queued up for the same remote port. Beef up log messages in this area.

This time window can be seconds long due to FSF_PROT_HOST_CONNECTION_INITIALIZING causing by design looping with exponential increase sleeps in the function performing exchange config data during recovery [zfcp_erp_adapter_strat_fsf_xconf()]. Recovery triggered by local link up. Suppose an event occurs for which the FCP channel would send an unsolicited notification to zfcp by means of a previously posted SRB. We saw it with local cable pull (link down) in multi-initiator zoning with multiple NPIV-enabled subchannels of the same shared FCP channel. As soon as zfcp_erp_adapter_strategy_open_fsf() starts posting the initial status read buffers from within the adapter's ERP thread, the channel does send an unsolicited notification. Since v2.6.27 commit d26ab06ede83 ("[SCSI] zfcp: receiving an unsolicted status can lead to I/O stall"), zfcp_fsf_status_read_handler() schedules adapter->stat_work to re-fill the just consumed SRB from a work item. Now the ERP thread and the work item post SRBs in parallel. Both contexts call the helper function zfcp_status_read_refill(). The tracking of missing (to be posted / re-filled) SRBs is not thread-safe due to separate atomic_read() and atomic_dec(), in order to depend on posting success. Hence, both contexts can see atomic_read(&adapter->stat_miss) == 1. One of the two contexts posts one too many SRB. Zfcp gets QDIO_ERROR_SLSB_STATE on the output queue (trace tag "qdireq1") leading to zfcp_erp_adapter_shutdown() in zfcp_qdio_handler_error(). An obvious and seemingly clean fix would be to schedule stat_work from the ERP thread and wait for it to finish. This would serialize all SRB re-fills. However, we already have another work item wait on the ERP thread: adapter->scan_work runs zfcp_fc_scan_ports() which calls zfcp_fc_eval_gpn_ft(). The latter calls zfcp_erp_wait() to wait for all the open port recoveries during zfcp auto port scan, but in fact it waits for any pending recovery including an adapter recovery. This approach leads to a deadlock. [see also v3.19 commit 18f87a67e6d6 ("zfcp: auto port scan resiliency"); v2.6.37 commit d3e1088d6873 ("[SCSI] zfcp: No ERP escalation on gpn_ft eval"); v2.6.28 commit fca55b6fb587 ("[SCSI] zfcp: fix deadlock between wq triggered port scan and ERP") fixing v2.6.27 commit c57a39a45a76 ("[SCSI] zfcp: wait until adapter is finished with ERP during auto-port"); v2.6.27 commit cc8c282963bd ("[SCSI] zfcp: Automatically attach remote ports")] Instead make the accounting of missing SRBs atomic for parallel execution in both the ERP thread and adapter->stat_work.

Things work by chance currently as under normal circumstances its the first CPU of each cluster which is used by the operating systems to probe the cooling devices. But as soon as this CPU ordering changes and any other CPU is used to bring up the cooling device, we will start seeing failures. Also the DT is rather incomplete when we list only one CPU in the cooling maps, as the hardware doesn't have any such limitations.

This approach has the advantage that the task management code becomes much easier to read and to verify since the number of potential race conditions against the command processing flow is strongly reduced. This patch has been tested by running the following two shell commands concurrently for about ten minutes for both the iSCSI and the SRP target drivers ($dev is an initiator device node connected with storage provided by the target driver under test): * fio with data verification enabled on a filesystem mounted on top of $dev. * while true; do sg_reset -d $dev; echo -n .; sleep .1; done Cc: Nicholas Bellinger Cc: Mike Christie Cc: Christoph Hellwig Cc: David Disseldorp Cc: Hannes Reinecke Signed-off-by: Bart Van Assche Signed-off-by: Martin K.

TAS handling is spread over the target core and the iSCSI target driver. If a LUN RESET is received, the target core will send the TASK_ABORTED response for all commands for which such a response has to be sent. If an ABORT TASK is received, only the iSCSI target driver will send the TASK_ABORTED response for the commands for which that response has to be sent. That is a bug since all target drivers have to honor the TAS bit. Fix this by moving the code that handles TAS from the iSCSI target driver into the target core. Additionally, if a command has been aborted, instead of sending the TASK_ABORTED status from the context that processes the SCSI command send it from the context of the ABORT TMF. The core_tmr_abort_task() change in this patch causes the CMD_T_TAS flag to be set if a TASK_ABORTED status has to be sent back to the initiator that submitted the command. If that flag has been set transport_cmd_finish_abort() will send the TASK_ABORTED response.

The SCSI architecture model does not require in-order delivery of such task management requests or processing by the task manager in the order received. To guarantee the processing order of task management requests referencing sent to a specific logical unit, an application client should not have more than one such task management request pending to that logical unit." This means that it is safe to use the system workqueues instead of tmr_wq for processing TMFs. An intended side effect of this patch is that it enables concurrent processing of TMFs.

For example, CONFIG_FOO=y exists in include/config/auto.conf but it is missing from the currently parsed Kconfig files, sym_lookup() allocates a new symbol, and sets its type to S_OTHER. Strangely, it will be set to S_STRING by conf_set_sym_val() a few lines below while it is obviously bool or tristate type. On the other hand, when CONFIG_BAR="bar" is being dropped from include/config/auto.conf, its type remains S_OTHER. Because for_all_symbols() omits S_OTHER symbols, conf_touch_deps() misses to touch include/config/bar.h This behavior has been a pretty mystery for me, and digging the git histroy did not help. At least, touching depfiles is broken for string type symbols. I removed S_OTHER entirely, and reimplemented it more simply. If CONFIG_FOO was visible in the previous syncconfig, but is missing now, what we want to do is quite simple; just call conf_touch_dep() to touch include/config/foo.h instead of allocating a new symbol data.

The gc algorithm will not evict PERMANENT entries as those entries are managed by userspace, yet the existing algorithm walks the entire hash table which means it always considers PERMANENT entries when looking for entries to evict. In some use cases (e.g., EVPN) there can be tens of thousands of PERMANENT entries leading to wasted CPU cycles when gc kicks in. As an example, with 32k permanent entries, neigh_alloc has been observed taking more than 4 msec per invocation. 2. Currently, when the number of neighbor entries hits gc_thresh2 and the last flush for the table was more than 5 seconds ago gc kicks in walks the entire hash table evicting *all* entries not in PERMANENT or REACHABLE state and not marked as externally learned. There is no discriminator on when the neigh entry was created or if it just moved from REACHABLE to another NUD_VALID state (e.g., NUD_STALE). It is possible for entries to be created or for established neighbor entries to be moved to STALE (e.g., an external node sends an ARP request) right before the 5 second window lapses: -----|---------x|----------|----- t-5 t t+5 If that happens those entries are evicted during gc causing unnecessary thrashing on neighbor entries and userspace caches trying to track them. Further, this contradicts the description of gc_thresh2 which says "Entries older than 5 seconds will be cleared". One workaround is to make gc_thresh2 == gc_thresh3 but that negates the whole point of having separate thresholds. 3. Clearing *all* neigh non-PERMANENT/REACHABLE/externally learned entries when gc_thresh2 is exceeded is over kill and contributes to trashing especially during startup. This patch addresses these problems as follows: 1. Use of a separate list_head to track entries that can be garbage collected along with a separate counter. PERMANENT entries are not added to this list. The gc_thresh parameters are only compared to the new counter, not the total entries in the table. The forced_gc function is updated to only walk this new gc_list looking for entries to evict. 2. Entries are added to the list head at the tail and removed from the front. 3. Entries are only evicted if they were last updated more than 5 seconds ago, adhering to the original intent of gc_thresh2. 4. Forced gc is stopped once the number of gc_entries drops below gc_thresh2. 5. Since gc checks do not apply to PERMANENT entries, gc levels are skipped when allocating a new neighbor for a PERMANENT entry. By extension this means there are no explicit limits on the number of PERMANENT entries that can be created, but this is no different than FIB entries or FDB entries.

These MSIX reported hardware errors are handled using common misc. interrupt handler. Hardware error related registers cannot be cleared in context to the interrupt received as they require *heavy* access to hardware using IMP(Integrated Mangement Processor) commands. Hence, we defer the clearing of such error events till later time. Since, we have defered exact identification of errors we will have to defer the level of receovery/reset which might be required. Hence, a new reset type UNKNOWN reset has been introduced which effectively defers the assertion of the reset till we get hold of kind of errors at later time.

At the same time the 'macirq' (eth0) IRQ would stop being triggered at all and as consequence the GMAC IRQs never ACKed. After a painful investigation the problem seemed to be due to a wrong defined IRQ type for the GMAC IRQ that should be LEVEL_HIGH instead of EDGE_RISING. The change in the macirq IRQ type also solved another long standing issue affecting this SoC/PHY where EEE was causing the network connection to die after stressing it with iperf3 (even though much sooner). It's now possible to remove the 'eee-broken-1000t' quirk as well.

In fact, most other system call handlers do the same thing these days, so let's follow the trend here and merge all of futex_compat.c into futex.c. In the process, a few minor changes have to be done to make sure everything still makes sense: handle_futex_death() and futex_cmpxchg_enabled() become local symbol, and the compat version of the fetch_robust_entry() function gets renamed to compat_fetch_robust_entry() to avoid a symbol clash. This is intended as a purely cosmetic patch, no behavior should change.

Similarly when an offloaded VXLAN device ceases being interesting (it is downed, or detached, or a front-panel port netdevice is detached from the bridge that the VXLAN device is attached to), any offloaded FDB entries need to be unoffloaded and unmarked. This attach / detach processing is implemented in this patchset. In patch #1, a code pattern is extracted into a named function for easier reuse. In patch #2, vxlan_fdb_replay() is added to send SWITCHDEV_VXLAN_FDB_ADD_TO_DEVICE for each FDB entry with a given VNI. The intention is that the offloading driver will interpret these events like any other and thus offload the FDB entries that existed prior to VXLAN attach. In patches #3 and #4, the functions vxlan_fdb_clear_offload() resp. br_fdb_clear_offload() are added. These clear the offloaded flag at matching FDB entries. In patches #5-#9, we introduce FID-type-specific and NVE-type-specific ops necessary to properly abstract invocations of the replay/clear functions. Finally patch #10 implements the FDB management. In patch #11, the mlxsw-specific test case is extended to check that the management of offload marks under the newly-supported situations is correct. Patch #12, from Ido, exercises the new code paths in actual functional test. v2: - Patch #1: - Modify vxlan_fdb_switchdev_notifier_info() to initialize the structure through a passed-in pointer argument, instead of returning it as a value. - Patch #2: - Adapt to API change in vxlan_fdb_switchdev_notifier_info() ==================== Signed-off-by: David S.

Similarly when VXLAN device is downed, the FDB entries are unoffloaded, and the marks thus need to be cleared. Similarly when a front-panel port device is attached to a bridge with a VXLAN device, or when VLAN flags are tweaked on a VXLAN port attached to a VLAN-aware bridge.

However, for cmpxchg() operations on types smaller than 64 bits, this constraint can result in an invalid instruction which is correctly rejected by GAS, such as EOR W1, W1, #0xffffffff. Whilst we could special-case the constraint based on the cmpxchg size, it's far easier to change the constraint to "K" and put up with using a register for large 64-bit immediates.

Probing the reset line with a 'scope while repeatedly attempting to bind the driver in a shell loop revealed that the KSZ8851 RSTN pin is constantly held at zero, meaning the device is held in reset, and does not respond on the SPI bus. Experimentation with the startup delay on the regulator set to 50ms shows that the reset is positively released after 20ms. Schematics for this board are not available, and the traces are buried in the inner layers of the board which makes tracing where the RSTN pin extremely difficult. We can only guess that the RSTN pin is wired to a reset generator chip driven off the ethernet supply, which fits the observed behaviour. Include this delay in the regulator startup delay - effectively treating the reset as a "supply stable" indicator. This can not be modelled as a delay in the KSZ8851 driver since the reset generation is board specific - if the RSTN pin had been wired to a GPIO, reset could be released earlier via the already provided support in the KSZ8851 driver. This also got confirmed by Peter Ujfalusi based on Blaze schematics that should be very close to SDP4430: TPS22902YFPR is used as the regulator switch (gpio48 controlled): Convert arm boot_lock to raw The VOUT is routed to TPS3808G01DBV. (SCH Note: Threshold set at 90%. Vsense: 0.405V). According to the TPS3808 data sheet the RESET delay time when Ct is open (this is the case in the schema): MIN/TYP/MAX: 12/20/28 ms.

Believed to be unused GPIO pin "hookflash1", apparently set high regardless of the corresponding bit of "latch2" port attempted to be set low during .init_machine(), has been identified as the reason. According to Amstrad E3 wiki, the purpose of the pin hasn't been clearly identified. Original Amstrad software used to produce a high pulse on it when the phone was taken off hook or recall was pressed. With the current finding, we can assume the pin provides a kind of audio mute function. Proper resolution of the issue should be done in two steps: - resolution of an issue with the pin state not reflecting the value the corresponding bit of the port was attempted to be initialized with, - extension of on-board audio driver with a new control. For now, rename the pin to "audio_mute" to reflect its function and, as a quick fix, hogg it as output low so on-board audio can produce audible sound again.

This leads to __video_register_device() falling back to the parent device of associated v4l2_device struct, which often does not match the physical device the subdevice is registered for. Due to the problem above, the links between real devices and v4l-subdev nodes cannot be obtained from sysfs, which might be confusing for the userspace trying to identify the hardware. Fix this by initializing the dev_parent field of the video_device struct with the value of dev field of the v4l2_subdev struct. In case of subdevices without a parent struct device, the field will be NULL and the old behavior will be preserved by the semantics of __video_register_device().

High-resolution scroll wheels are supposed to use a fraction of 120 to signal smaller scroll steps. This is implemented by the Resolution Multiplier in the device itself. If the multiplier is present in the report descriptor, set it to the logical max and then use the resolution multiplier to calculate the high-resolution events. This is the recommendation by Microsoft, see http://msdn.microsoft.com/en-us/windows/hardware/gg487477.aspx Note that all mice encountered so far have a logical min/max of 0/1, so it's a binary "yes or no" to high-res scrolling anyway. To make userspace simpler, always enable the REL_WHEEL_HI_RES bit. Where the device doesn't support high-resolution scrolling, the value for the high-res data will simply be a multiple of 120 every time. For userspace, if REL_WHEEL_HI_RES is available that is the one to be used. Potential side-effect: a device with a Resolution Multiplier applying to other Input items will have those items set to the logical max as well. This cannot easily be worked around but it is doubtful such devices exist.

If the multiplier is set to anything but 1, the hardware reports (value * multiplier) for the same amount of physical movement, i.e. the value we receive in the kernel is pre-multiplied. The hardware may either send a single (value * multiplier), or by sending multiplier as many reports with the same value, or a combination of these two options. For example, when the Microsoft Sculpt Ergonomic mouse Resolution Multiplier is set to 12, the Wheel sends out 12 for every detent but AC Pan sends out a value of 3 at 4 times the frequency. The effective multiplier is based on the physical min/max of the multiplier field, a logical min/max of [0,1] with a physical min/max of [1,8] means the multiplier is either 1 or 8. The Resolution Multiplier was introduced for high-resolution scrolling in Windows Vista and is commonly used on Microsoft mice. The recommendation for the Resolution Multiplier is to default to 1 for backwards compatibility. This patch adds an arbitrary upper limit at 255. The only known use case for the Resolution Multiplier is for scroll wheels where the multiplier has to be a fraction of 120 to work with Windows.

The value 120 is one detent (wheel click) of movement. Mice with higher-resolution scrolling can send fractions of 120 which must be accumulated in userspace. Userspace can either wait for a full 120 to accumulate or scroll by fractions of one logical scroll movement as the events come in. 120 was picked as magic number because it has a high number of integer fractions that can be used by high-resolution wheels.

But worth mentioning that checking for port link resume state is now behind a additional port power check. This is fine as ports can't be in resume state if port power bit is not set. xhci spec section 4.19.1.1.6 figure 34 shows that port power bit must be set for all 'Enable' substates, including U0,U1,U2,U3 (suspended), Resume, and RExit states.

Actually, what this does is to initialize the first element of the struct to zero. According to C99 Standard 6.7.8.21: "If there are fewer initializers in a brace-enclosed list than there are elements or members of an aggregate, or fewer characters in a string literal used to initialize an array of known size than there are elements in the array, the remainder of the aggregate shall be initialized implicitly the same as objects that have static storage duration." So, in practice, it could zero the entire struct, but, if the first element is not an integer, it will produce warnings: drivers/staging/media/sunxi/cedrus/cedrus.c:drivers/staging/media/sunxi/cedrus/cedrus.c:78:49: warning: Using plain integer as NULL pointer drivers/staging/media/sunxi/cedrus/cedrus_dec.c:drivers/staging/media/sunxi/cedrus/cedrus_dec.c:29:35: warning: Using plain integer as NULL pointer As the right initialization would be, instead: struct foo f = { NULL }; Another way to initialize it with gcc is to use: struct foo f = {}; That seems to be a gcc extension, but clang also does the right thing, and that's a clean way for doing it. Anyway, I decided to check upstream what's the most commonly pattern. The "= {}" pattern has about 2000 entries: $ git grep -E "=\s*\{\s*\}"|wc -l 1951 The standard-C compliant pattern has about 2500 entries: $ git grep -E "=\s*\{\s*NULL\s*\}"|wc -l 137 $ git grep -E "=\s*\{\s*0\s*\}"|wc -l 2323 Meaning that developers have split options on that. So, let's opt to the simpler form.

The V4L2 M2M API ensures that only one decoding job runs at a time, so the interrupt signaling the end of decoding will not occur while the next picture is being configured. Spurious interrupts are taken care of in the handler, by checking that we have a valid M2M context and a decoding status available before marking the buffers as done. In addition, holding a spin lock could be problematic if non-atomic operations are required in the setup process for future codec support. As a result, remove the global IRQ spin lock.

This can cause the thundering-herd problem. To reduce the problem, we make use of the (new) fact that a pending request can itself have a list of blocked requests. When we find a conflict, we look through the existing blocked requests. If any one of them blocks the new request, the new request is attached below that request, otherwise it is added to the list of blocked requests, which are now known to be mutually non-conflicting. This way, when the lock is released, only a set of non-conflicting locks will be woken, the rest can stay asleep. If the lock request cannot be granted and the request needs to be requeued, all the other requests it blocks will then be woken To make this more concrete: If you have a many-core machine, and have many threads all wanting to briefly lock a give file (udev is known to do this), you can get quite poor performance. When one thread releases a lock, it wakes up all other threads that are waiting (classic thundering-herd) - one will get the lock and the others go to sleep. When you have few cores, this is not very noticeable: by the time the 4th or 5th thread gets enough CPU time to try to claim the lock, the earlier threads have claimed it, done what was needed, and released. So with few cores, many of the threads don't end up contending. With 50+ cores, lost of threads can get the CPU at the same time, and the contention can easily be measured. This patchset creates a tree of pending lock requests in which siblings don't conflict and each lock request does conflict with its parent. When a lock is released, only requests which don't conflict with each other a woken. Testing shows that lock-acquisitions-per-second is now fairly stable even as the number of contending process goes to 1000. Without this patch, locks-per-second drops off steeply after a few 10s of processes. There is a small cost to this extra complexity. At 20 processes running a particular test on 72 cores, the lock acquisitions per second drops from 1.8 million to 1.4 million with this patch. For 100 processes, this patch still provides 1.4 million while without this patch there are about 700,000. Reported-and-tested-by: Martin Wilck Signed-off-by: NeilBrown Reviewed-by: J.

Now that requests can block other requests, we need to be careful to always clean up those blocked requests. Any time that we wait for a request, we might have other requests attached, and when we stop waiting, we must clean them up. If the lock was granted, the requests might have been moved to the new lock, though when merged with a pre-exiting lock, this might not happen. In all cases we don't want blocked locks to remain attached, so we remove them to be safe. Signed-off-by: NeilBrown Reviewed-by: J.

The reason for the quirk is that there are two settings which produces same divider value for the SDn clock. On the effected boards the one currently selected results in HS400 not working. This change uses the same method as the Gen2 CPG driver and simply ignores the first clock setting as this is the offending one when selecting the settings.

This can be problematic for two reasons. 1. If the clock driver can't figure out the state of the clock, registration of the clock fails, and setting of a known state by a clock user is not possible. 2. The state of the clock depends on if and how the bootloader configured it. The driver only checks that the rate is known, not if the clock is stopped or not for example. Fix this by setting a known state and making sure the clock is stopped.

Now snd_hda_jack_add_kctl() receives two more arguments: the jack type and the jack keymaps. Both are optional, and when zero are passed, the function behaves just like before. For reporting button state changes, you'd need to update jack->button_state bits accordingly, typically in the jack callback. Then the value OR'ed with button_state and the jack plug state is passed to snd_jack_report(). Note that currently the code assumes only the one-shot button events, i.e. it tries to send the button release soon after sending the button event. If a driver really supports the button release handling by itself, we may need to introduce some flag to control this behavior in future.

The new interrupt controller driver allows to configure and capture edge or level interrupts on 8 arbitrary selectedinput GPIO pins, and lift the signals to be reported as NVIC rising edge interrupts. Configuration of a particular GPIO pin to serve as interrupt and its mapping to an interrupt on NVIC is done by SCU pin controller, for more details see description of 'nxp,gpio-pin-interrupt' device tree property of a GPIO pin [1]. From LPC18xx and LPC43xx User Manuals the GPIO controller consists of the following blocks: * GPIO pin interrupt block at 0x40087000, this change adds its support, * GPIO GROUP0 interrupt block at 0x40088000, * GPIO GROUP1 interrupt block at 0x40089000, * GPIO port block at 0x400F4000, it is supported by the original driver.

Likely support of two GPIO group interrupt blocks won't be added in short term, because the mechanism to mask several interrupt sources is not well defined.

This is done by sending NAND_CMD_RESET. The Denali IP provides another way to do the equivalent thing; if a bit is set in the DEVICE_RESET register, the controller sends the RESET command to the corresponding device. denali_reset_banks() uses it to reset all devices beforehand. This redundant reset sequence was needed to know the actual number of chips before calling nand_scan_ident(); if DEVICE_RESET fails, there is no chip in that chip select. Then, denali_reset_banks() sets denali->max_banks to the number of detected chips. As commit f486287d2372 ("mtd: nand: denali: fix bank reset function to detect the number of chips") explained, nand_scan_ident() issued Set Features (0xEF) command to all CS lines, some of which may not be connected with a chip. Then, the driver would wait for R/B# response, which never happens. This problem was solved by commit 107b7d6a7ad4 ("mtd: rawnand: avoid setting again the timings to mode 0 after a reset"). In the current code, nand_setup_data_interface() is called from nand_scan_tail(), which is invoked after the chip detection. Now, we can really remove the redundant denali_nand_banks() by simply passing the maximum number of chip selects supported by this IP (typically 4 or 8) to nand_scan(). Let's leave all the chip detection process to nand_scan_ident().

Instead, denali_dev_ready() checks if the R/B# transition has already happened. (The INTR__INT_ACT interrupt is asserted at the rising edge of the R/B# pin.) It is not a correct way to implement the ->dev_ready() hook. In fact, it has a drawback; in the nand_scan_ident phase, the chip detection iterates over maxchips until it fails to find a homogeneous chip. For the last loop, nand_reset() fails if no chip is there. If ->dev_ready hook exists, nand_command(_lp) calls nand_wait_ready() after NAND_CMD_RESET. However, we know denali_dev_ready() never returns 1 unless there exists a chip that toggles R/B# in that chip select. Then, nand_wait_ready() just ends up with wasting 400 msec, in the end, shows the "timeout while waiting for chip to become ready" warning. Let's remove the mis-implemented dev_ready hook, and fallback to sending the NAND_CMD_STATUS and nand_wait_status_ready(), which bails out more quickly.

This causes issues when the actual PHY driver attempts to claim the same GPIO descriptors. For example, tusb1210 now fails to probe with: tusb1210: probe of dwc3.0.auto.ulpi failed with error -16 (EBUSY) dwc3-pci needs to turn on the PHY once before dwc3 is loaded, but usually the PHY driver will then hold the GPIOs to turn off the PHY when requested (e.g. during suspend). To fix the problem, this reverts the commit to restore the old behavior to put the GPIOs immediately after usage.

This ERROR field will remain until the next time when DC8051 transitions from Offline to Polling. Subsequently, when the host requests DC8051 to change its physical state to Polling again, it may receive a DC8051 interrupt with the stale ERROR field still in DC8051_DBG_ERR_INFO_SET_BY_8051. If the host link state has been changed to Polling, this stale ERROR will force the host to transition to Offline state, resulting in a vicious cycle of Polling ->Offline->Polling->Offline. On the other hand, if the host link state is still Offline when the stale ERROR is received, the stale ERROR will be ignored, and the link will come up correctly. This patch implements the correct behavior by changing host link state to Polling only after DC8051 changes its physical state to Polling.

Miller Date: Thu Dec 6 13:26:07 2018 -0800 Merge branch 'Pass-extack-to-NETDEV_PRE_UP' Petr Machata says: ==================== Pass extack to NETDEV_PRE_UP Drivers may need to validate configuration of a device that's about to be upped. An example is mlxsw, which needs to check the configuration of a VXLAN device attached to an offloaded bridge. Should the validation fail, there's currently no way to communicate details of the failure to the user, beyond an error number. Therefore this patch set extends the NETDEV_PRE_UP event to include extack, if available. There are three vectors through which NETDEV_PRE_UP invocation can be reached. The two major ones are dev_open() and dev_change_flags(), the last is then __dev_change_flags(). In patch #1, the first access vector, dev_open() is addressed. An extack parameter is added and all users converted to use it. Before addressing the second vector, two preparatory patches propagate extack argument to the proximity of the dev_change_flags() call in VRF and IPVLAN drivers. That happens in patches #2 and #3. Then in patch #4, dev_change_flags() is treated similarly to dev_open(). Likewise in patch #5, __dev_change_flags() is extended. Then in patches #6 and #7, the extack is finally propagated all the way to the point where the notification is emitted. This change allows particularly mlxsw (which already has code to leverage extack if available) to communicate to the user error messages regarding VXLAN configuration. In patch #8, add a test case that exercises this code and checks that an error message is propagated. For example: local 192.0.2.17 remote 192.0.2.18 \ dstport 4789 nolearning noudpcsum tos inherit ttl 100 local 192.0.2.17 remote 192.0.2.18 \ dstport 4789 nolearning noudpcsum tos inherit ttl 100 Error: mlxsw_spectrum: Conflicting NVE tunnels configuration. v2: - Add David Ahern's tags. ==================== Signed-off-by: David S.

Currently this is handled in the driver's probe() routine, and set up for every domain present, even if it will not be controlled directly by SYSC (CPU domains are powered through the APMU on R-Car Gen2 and later). On R-Car Gen3, PSCI powers down the SoC during system suspend, thus losing any configured interrupt state. Hence after system resume, power domains not controlled through the APMU (e.g. A3IR, A3VC, A3VP) fail to power up. Fix this by replacing the global interrupt setup in the probe() routine by a domain-specific interrupt setup in rcar_sysc_power(), where the domain's power is actually controlled. This brings the code more in line with the flowchart in the Hardware User's Manual.

As they are just one-line wrappers around rcar_sysc_power(), it makes sense to just remove them. This also avoids a bool/helper/bool conversion in rcar_sysc_power_cpu(), where a bool is checked to call one of two helper functions, which just call rcar_sysc_power() with hardcoded boolean values again.

This can be seen for example on Jetson TX2. Under certain circumstances the generic power domain code will cause the SOR to be reset. However, if the power domain is never powered off (this can happen if the HDA controller is enabled, which is part of the same power domain as the SOR), then the SOR will end up not getting reset and fail to properly set a mode. To work around this, try to get the reset control and assert/deassert it, irrespective of whether or not a generic power domain is attached to the SOR. On platforms where the kernel implements generic power domains (up to Tegra210) this will fail, because the power domain will already have acquired an exclusive reference to the reset control. But on recent platforms there the BPMP provides an ABI to control power domains, it's possible to acquire the reset control from SOR and use it to put the SOR into a known good state at probe time. The proper solution for this is to make the SOR driver capable of dealing with hardware that's already up and running (by first grace- fully shutting it down, or perhaps by seamlessly transitioning to the kernel driver and taking over the running display configuration). That is fairly involved, though, so we'll go with this quickfix for now.

Overall there have been some minor differences. This patch covers the following: - average clock rate of the internal RC oscillator + presence of fixed and adjustable prescaler for this clock - availability of an external (to the SoC) clock output One major difference regarding the H6 is the 24 MHz crystal is now routed through the RTC, as a digitally compensated oscillator (DCXO). This is not covered in this patch and will be supported later. Other differences are either unrelated to RTC or clock functionality, such as boot or crypto related registers, or the driver simply doesn't use the feature in question. One example of the latter is the calibration function for the RC oscillator. We consider this clock to be very bad and avoid using it.

These include a lack of an external clock output (A31), different internal oscillator frequencies (H3/H5/A64/V3/V3s), different regulator voltage settings (H5/H6), and the presence of miscellaneous registers unrelated to the RTC (A64/R40/H5/H6). The datasheet also describes different number of registers for non-volatile storage, though based on actual experiments the actual number is the same across the board. This patch adds a list of all pre-H6 variants, grouped by the internal oscillator's clock rate, regulator settings, and the presence of the external clock output. Combinations are introduced for the variants that have miscellaneous registers. The RTC block in the H6 also handles the 24 MHz DCXO. This will require more device tree binding changes and will be done later.

This is necessary on some hardware such as the D-Link DIR-685 where all flash pins are patched in/out at the same time, but some of the flash pins are in practice unused by the flash and have anyway been reused as GPIO. This concerns specifically CE1 on the Gemini. There is only one flash chip, so only CE0 is used, and the line for CE1 has been reused as chip select for the emulated SPI port connected to the display. If we try to use the same lines for flash and GPIO at the same time, one of them will loose: the GPIO line will disappear because it gets disconnected from the pin when the flash group is muxed out. Fix this by introducing two pin control states named simply "enabled" and "disabled" and only enable the flash lines when absolutely necessary (during read/write/copy). This way, they are available for GPIO at all other times and the display works. Collect all the state variables in a struct named struct gemini_flash and allocate this struct at probe time.

We iterate over each of these tables for various operations (e.g, detection, verification etc.). We do not have a way to map a system "capability" to its entry, (i.e, cap -> struct arm64_cpu_capabilities) which is needed for this_cpu_has_cap(). So we iterate over the table one by one to find the entry and then do the operation. Also, this prevents us from optimizing the way we "enable" the capabilities on the CPUs, where we now issue a stop_machine() for each available capability. One solution is to merge the two tables into a single table, sorted by the capability. But this is has the following disadvantages: - We loose the "classification" of an errata vs. feature - It is quite easy to make a mistake when adding an entry, unless we sort the table at runtime. So we maintain a list of pointers to the capability entry, sorted by the "cap number" in a separate array, initialized at boot time. The only restriction is that we can have one "entry" per capability. While at it, remove the duplicate declaration of arm64_errata table.

The idea behind this is that the async_synchronize_full call will only guarantee that any existing async operations are flushed. This doesn't do anything to guarantee that a hotplug event that may occur while we are doing the release of the driver will not be asynchronously scheduled. By moving this into the driver_detach path we can avoid potential deadlocks as we aren't holding the device lock at this point and we should not have the driver we want to flush loaded so the flush will take care of any asynchronous events the driver we are detaching might have scheduled.

This is rather unusual and many callers have to convert it to errno value. The callers are highly inconsistent with error codes ranging from -ENOMEM over -EIO, -EINVAL and -EFAULT ranging to -EAGAIN. Return -ENOMEM which seems to be what the largest number of callers convert it to, and which also matches the typical error case where we are out of resources.

That means we require an additional indirect call to figure out if a dma mapping call returned an error, and a lot of boilerplate code to implement these semantics. Instead return the maximum addressable value as the error. As long as we don't allow mapping single-byte ranges with single-byte alignment this value can never be a valid return. Additionaly if drivers do not check the return value from the dma_map* routines this values means they will generally not be pointed to actual memory. Once the default value is added here we can start removing the various mapping_error methods and just rely on this generic check.

Pass struct device of the parent to snd_pcm_lib_preallocate_pages() so dma_alloc_coherent() can use correct dma_ops. Otherwise, it will use default dma_ops which is nommu_dma_ops on x86_64 even when IOMMU is enabled and set to non passthrough mode. Though platform device inherits some dma related fields during its creation in mfd_add_device(), we can't simply pass its struct device to snd_pcm_lib_preallocate_pages() because dma_ops is not among the inherited fields. Even it were, drivers/iommu/amd_iommu.c would ignore it because get_device_id() doesn't handle platform device.

But when calculated, the old node timer interval only updated if current setting value (tolerance/4) less than old ones regardless of number of links as well as links' lowest tolerance value. This caused to two cases missing if tolerance changed as following: Case 1: 1.1/ There is one link (L1) available in the system 1.2/ Set L1's tolerance from 1500ms => lower (i.e 500ms) 1.3/ Then, fallback to default (1500ms) or higher (i.e 2000ms) Expected: node timer interval is 1500/4=375ms after 1.3 Result: node timer interval will not being updated after changing tolerance at 1.3 since its value 1500/4=375ms is not less than 500/4=125ms at 1.2. Case 2: 2.1/ There are two links (L1, L2) available in the system 2.2/ L1 and L2 tolerance value are 2000ms as initial 2.3/ Set L2's tolerance from 2000ms => lower 1500ms 2.4/ Disable link L2 (bring down its bearer) Expected: node timer interval is 2000ms/4=500ms after 2.4 Result: node timer interval will not being updated after disabling L2 since its value 2000ms/4=500ms is still not less than 1500/4=375ms at 2.3 although L2 is already not available in the system. To fix this, we start the node interval calculation by initializing it to a value larger than any conceivable calculated value. This way, the link with the lowest tolerance will always determine the calculated value. Acked-by: Jon Maloy Signed-off-by: Hoang Le Signed-off-by: David S.

It is different from the behavior in jited_func_lens/nr_jited_func_lens, jited_ksyms/nr_jited_ksyms...etc. This patch fixes it. (i.e. set func_info to 0 instead of func_info_cnt to 0 when bpf_dump_raw_ok() == false). 2) When the userspace passed in info.func_info_cnt == 0, the kernel will set the expected func_info size back to the info.func_info_rec_size. It is a way for the userspace to learn the kernel expected func_info_rec_size introduced in commit 838e96904ff3 ("bpf: Introduce bpf_func_info"). An exception is the kernel expected size is not set when func_info is not available for a bpf_prog. This makes the returned info.func_info_rec_size has different values depending on the returned value of info.func_info_cnt. This patch sets the kernel expected size to info.func_info_rec_size independent of the info.func_info_cnt. 3) The current logic only rejects invalid func_info_rec_size if func_info_cnt is non zero. This patch also rejects invalid nonzero info.func_info_rec_size and not equal to the kernel expected size. 4) Set info.btf_id as long as prog->aux->btf != NULL. That will setup the later copy_to_user() codes look the same as others which then easier to understand and maintain. prog->aux->btf is not NULL only if prog->aux->func_info_cnt > 0. Breaking up info.btf_id from prog->aux->func_info_cnt is needed for the later line info patch anyway. A similar change is made to bpf_get_prog_name().

Patch 01 converts it to use the generic kernel rhashtable which simplifies the code a lot and removes duplicated functionality. The convert also makes hash_elasticity obsolete as the generic rhashtable already has such checks and has a fixed elasticity of RHT_ELASTICITY (16 currently) so we emit a warning whenever elasticity is set and return RHT_ELASTICITY when read (patch 03). Patch 02 converts the multicast code to use non-bh RCU flavor as it was mixing bh and non-bh. Since now we have the generic rhashtable which autoshrinks we can be more liberal with the default hash maximum so patch 04 increases it to 4096 and moves it to a define in br_private.h. v3: add non-rcu br_mdb_get variant and use it where we have multicast_lock, drop special hash_max handling and just set it where needed and use non-bh RCU consistently (patch 02, new) v2: send the latest version of the set which handles when IGMP snooping is not defined, changes are in patch 01 ==================== Signed-off-by: David S.

Miller commit 19e3a9c90c53479fecaa02307bf2db5ab8b3ffe3 Author: Nikolay Aleksandrov Date: Wed Dec 5 15:14:24 2018 +0200 net: bridge: convert multicast to generic rhashtable The bridge multicast code currently uses a custom resizable hashtable which predates the generic rhashtable interface. It has many shortcomings compared and duplicates functionality that is presently available via the generic rhashtable, so this patch removes the custom rhashtable implementation in favor of the kernel's generic rhashtable. The hash maximum is kept and the rhashtable's size is used to do a loose check if it's reached in which case we revert to the old behaviour and disable further bridge multicast processing. Also now we can support any hash maximum, doesn't need to be a power of 2. v3: add non-rcu br_mdb_get variant and use it where multicast_lock is held to avoid RCU splat, drop hash_max function and just set it directly v2: handle when IGMP snooping is undefined, add br_mdb_init/uninit placeholders Signed-off-by: Nikolay Aleksandrov Signed-off-by: David S.

Signed-off-by: Baolin Wang Signed-off-by: Sebastian Reichel commit ff4dd232ec45a0e45ea69f28f069f2ab22b4908a Author: Paul Burton Date: Tue Dec 4 23:44:12 2018 +0000 MIPS: Expand MIPS32 ASIDs to 64 bits ASIDs have always been stored as unsigned longs, ie. 32 bits on MIPS32 kernels. This is problematic because it is feasible for the ASID version to overflow & wrap around to zero. We currently attempt to handle this overflow by simply setting the ASID version to 1, using asid_first_version(), but we make no attempt to account for the fact that there may be mm_structs with stale ASIDs that have versions which we now reuse due to the overflow & wrap around. Encountering this requires that: 1) A struct mm_struct X is active on CPU A using ASID (V,n). 2) That mm is not used on CPU A for the length of time that it takes for CPU A's asid_cache to overflow & wrap around to the same version V that the mm had in step 1. During this time tasks using the mm could either be sleeping or only scheduled on other CPUs. 3) Some other mm Y becomes active on CPU A and is allocated the same ASID (V,n). 4) mm X now becomes active on CPU A again, and now incorrectly has the same ASID as mm Y. Where struct mm_struct ASIDs are represented above in the format (version, EntryHi.ASID), and on a typical MIPS32 system version will be 24 bits wide & EntryHi.ASID will be 8 bits wide. The length of time required in step 2 is highly dependent upon the CPU & workload, but for a hypothetical 2GHz CPU running a workload which generates a new ASID every 10000 cycles this period is around 248 days. Due to this long period of time & the fact that tasks need to be scheduled in just the right (or wrong, depending upon your inclination) way, this is obviously a difficult bug to encounter but it's entirely possible as evidenced by reports. In order to fix this, simply extend ASIDs to 64 bits even on MIPS32 builds. This will extend the period of time required for the hypothetical system above to encounter the problem from 28 days to around 3 trillion years, which feels safely outside of the realms of possibility. The cost of this is slightly more generated code in some commonly executed paths, but this is pretty minimal: | Code Size Gain | Percentage -----------------------|----------------|------------- decstation_defconfig | +270 | +0.00% 32r2el_defconfig | +652 | +0.01% 32r6el_defconfig | +1000 | +0.01% I have been unable to measure any change in performance of the LMbench lat_ctx or lat_proc tests resulting from the 64b ASIDs on either 32r2el_defconfig+interAptiv or 32r6el_defconfig+I6500 systems.

Such failures are usually propagated into userspace, which has no way of distignuishing them from actual allocation failures and thus doesn't handle them gracefully. Such situation can be triggered e.g. by the following reproducer: while true; do load_policy; echo -n .; sleep 0.1; done & for (( i = 0; i < 1024; i++ )); do runcon -l s0:c$i echo -n x || break # or: # chcon -l s0:c$i || break done This patch overhauls the sidtab so it doesn't need to be frozen during policy reload, thus solving the above problem. The new SID table leverages the fact that SIDs are allocated sequentially and are never invalidated and stores them in linear buckets indexed by a tree structure. This brings several advantages: 1. Fast SID -> context lookup - this lookup can now be done in logarithmic time complexity (usually in less than 4 array lookups) and can still be done safely without locking. 2. No need to re-search the whole table on reverse lookup miss - after acquiring the spinlock only the newly added entries need to be searched, which means that reverse lookups that end up inserting a new entry are now about twice as fast. 3. No need to freeze sidtab during policy reload - it is now possible to handle insertion of new entries even during sidtab conversion. The tree structure of the new sidtab is able to grow automatically to up to about 2^31 entries (at which point it should not have more than about 4 tree levels). The old sidtab had a theoretical capacity of almost 2^32 entries, but half of that is still more than enough since by that point the reverse table lookups would become unusably slow anyway... The number of entries per tree node is selected automatically so that each node fits into a single page, which should be the easiest size for kmalloc() to handle. Note that the cache for reverse lookup is preserved with equivalent logic. The only difference is that instead of storing pointers to the hash table nodes it stores just the indices of the cached entries. The new cache ensures that the indices are loaded/stored atomically, but it still has the drawback that concurrent cache updates may mess up the contents of the cache. Such situation however only reduces its effectivity, not the correctness of lookups. Tested by selinux-testsuite and thoroughly tortured by this simple stress test: ``` function rand_cat() { echo $(( $RANDOM % 1024 )) } function do_work() { while true; do echo -n "system_u:system_r:kernel_t:s0:c$(rand_cat),c$(rand_cat)" \ >/sys/fs/selinux/context 2>/dev/null || true done } do_work >/dev/null & do_work >/dev/null & do_work >/dev/null & while load_policy; do echo -n .; sleep 0.1; done kill %1 kill %2 kill %3 ``` Link: https://github.com/SELinuxProject/selinux-kernel/issues/38 Reported-by: Orion Poplawski Reported-by: Li Kun Signed-off-by: Ondrej Mosnacek Reviewed-by: Stephen Smalley [PM: most of sidtab.c merged by hand due to conflicts] [PM: checkpatch fixes in mls.c, services.c, sidtab.c] Signed-off-by: Paul Moore commit 037602705109ec2ab96340bea93ad87daa3ac046 Author: Max Filippov Date: Wed Dec 5 12:48:19 2018 -0800 xtensa: don't use l32r opcode directly xtensa assembler is capable of representing register loads with either movi + addmi, l32r or const16, depending on the core configuration.

Also, module_alloc() is in charge of allocating KASAN shadow memory when running with KASAN enabled. This means that the way BPF reuses module_alloc()/module_memfree() is undesirable on arm64 (and potentially other architectures as well), and so this series refactors BPF's use of those functions to permit architectures to change this behavior. Patch #1 breaks out the module_alloc() and module_memfree() calls into __weak functions so they can be overridden. Patch #2 implements the new alloc/free overrides for arm64 Changes since v3: - drop 'const' modifier for free() hook void* argument - move the dedicated BPF region to before the module region, putting it within 4GB of the module and kernel regions on non-KASLR kernels Changes since v2: - properly build time and runtime tested this time (log after the diffstat) - create a dedicated 128 MB region at the top of the vmalloc space for BPF programs, ensuring that the programs will be in branching range of each other (which we currently rely upon) but at an arbitrary distance from the kernel and modules (which we don't care about) Changes since v1: - Drop misguided attempt to 'fix' and refactor the free path.

So using the same region for programs that do not have this restriction is wasteful, and preferably avoided. Now that the core BPF JIT code permits the alloc/free routines to be overridden, implement them by vmalloc()/vfree() calls from a dedicated 128 MB region set aside for BPF programs. This ensures that BPF programs are still in branching range of each other, which is something the JIT currently depends upon (and is not guaranteed when using module_alloc() on KASLR kernels like we do currently). It also ensures that placement of BPF programs does not correlate with the placement of the core kernel or modules, making it less likely that leaking the former will reveal the latter. This also solves an issue under KASAN, where shadow memory is needlessly allocated for all BPF programs (which don't require KASAN shadow pages since they are not KASAN instrumented) Signed-off-by: Ard Biesheuvel Acked-by: Will Deacon Signed-off-by: Daniel Borkmann commit dc002bb62f10c5905420f8b8a7d5ec0da567fc82 Author: Ard Biesheuvel Date: Fri Nov 23 23:18:03 2018 +0100 bpf: add __weak hook for allocating executable memory By default, BPF uses module_alloc() to allocate executable memory, but this is not necessary on all arches and potentially undesirable on some of them.

When pressing it, the Embedded Controller send hid report via I2C and switch the airplane mode indicator LED based on the status. However, it's not working because it fails to be identified as a hidinput device. It fails in hidinput_connect() due to the macro IS_INPUT_APPLICATION doesn't have HID_GD_WIRELESS_RADIO_CTLS as a legit application code. It's easy to add the HID I2C vendor and product id to the quirk list and apply HID_QUIRK_HIDINPUT_FORCE to make it work. But it makes more sense to support it as a generic input application.

Another advantage of that is that ieee80211_wake_txqs might call the wake_tx_queue() callback and then the driver may call mac80211 which will call it back in the same context. The bug I saw is that when we send a deauth frame as a station we do: flush(drop=1) tx deauth flush(drop=0) While we flush we stop the queues and wake them up immediately after we finished flushing. The problem here is that the tasklet that de-facto enables the queue may not have run until we send the deauth. Then the deauth frame is sent to the driver (which is surprising by itself), but the driver won't get anything useful from ieee80211_tx_dequeue because the queue is stopped (or more precisely because vif->txqs_stopped[0] is true). Then the deauth is not sent. Later on, the tasklet will run, but that'll be too late. We'll already have removed all the vif etc... Fix this by calling ieee80211_wake_txqs synchronously if we are not waking up the queues from the driver (we check the reason to determine that). This makes the code really convoluted because we may call ieee80211_wake_txqs from __ieee80211_wake_queue. The latter assumes that queue_stop_reason_lock has been taken by the caller and ieee80211_wake_txqs may release the lock to send the frames.

If necessary, it can also be set up one step removed from an existing network device, such as through a vlan/80211Q or macvlan connection to not disrupt the existing network interface. To use it to wrap a bare ethernet connection: ip link add link eth0 name wlan0 type virt_wifi You may have to rename or otherwise hide the eth0 from your connection manager, as the original network link will become unusuable and only the wireless wrapper will be functional. This can also be combined with vlan or macvlan links on top of eth0 to share the network between distinct links, but that requires support outside the machine for accepting vlan-tagged packets or packets from multiple MAC addresses. This is being used for Google's Remote Android Virtual Device project, which runs Android devices in virtual machines. The standard network interfaces provided inside the virtual machines are all ethernet. However, Android is not interested in ethernet devices and would rather connect to a wireless interface. This patch allows the virtual machine guest to treat one of its network connections as wireless rather than ethernet, satisfying Android's network connection requirements. We believe this is a generally useful driver for simulating wireless network connections in other environments where a wireless connection is desired by some userspace process but is not available. This is distinct from other testing efforts such as mac80211_hwsim by being a cfg80211 device instead of mac80211 device, allowing straight pass-through on the data plane instead of forcing packaging of ethernet data into mac80211 frames.

Clearing the GPIO_EN bit means that if the pin was an output it is now effectively floating. The datasheet is not clear what happens to pull ups / downs in this case, but from testing it looks like these are disabled too, also floating input pins. One example where this is causing issues is the soc_button_array input driver, this parses ACPI tables to create 2 platform devices for the gpio_keys input driver. The list of GPIOs is passed through struct gpio_keys_platform_data which uses gpio numbers rather then gpio_desc pointers. The buttons handled by this drivers short the pin to ground when pressed and the volume buttons rely on the SoC's internal pull-up to pull the pin high when the button is not pressed. To get the gpio number, the soc_button_array code calls gpiod_get_index followed by a desc_to_gpio call and then gpiod_put on the gpio_desc. This last call causes chv_gpio_disable_free to clear the GPIO_EN bit. When the gpio_keys driver then loads next it gets the gpio_desc again causing the GPIO_EN bit to be set again and immediately reads the GPIO value which for the volume buttons reads 0 at this time, causing a spurious press of the volume buttons to get reported. Putting a small delay between the gpio_desc request and the read fixes this, I assume that this is caused by the pull-up being temporarily disabled while the GPIO_EN bit is cleared as the powerbutton which also has its GPIO_EN bit cleared does not have this problem. The soc_button_array code is not the only code temporarily requesting GPIOs the DWC3 PCI code also does this, to set the enable and reset GPIOs for the external phy, so that the code instantiating the ULPI phy can read the vendor and product ID registers from the phy. These GPIOs are released after this so that the PHY driver can claim and use them when it loads. Another example of temporary GPIO usage would be a user-space set_gpio utility using the userspace ioctls to set a GPIO as output value 0 or 1, having the GPIO revert to floating as soon as this utility exits would certainly be unexpected behavior. One argument in favor of clearing the GPIO_EN bit is if the GPIO is going to be muxed to another function after being released, but in that case chv_pinmux_set_mux() already clears it. TL;DR: Clearing the GPIO_EN bit from is a bad idea, this commit therefor removes the clearing from chv_gpio_disable_free(), replacing it with code to clear the interrupt-trigger condition so that the GPIO stops generating interrupts when released, as pinctrl-baytrail.c does. Note this commit adds a !chv_pad_locked() condition to the trigger clearing call, which the original GPIO_EN clearing code was missing.

In this case, 640x480 and 1024x768 are actually fixed by this change. Indeed, the sensor was sending data at, for example, 27.33fps instead of 30fps. This is -9%, which is roughly what we're seeing in the array. Testing these modes with the new clock setup actually fix that error, and data are now sent at around 30fps. 2592x1944, on the other hand, is probably due to the fact that this mode can only be used using MIPI-CSI2, in a two lane mode, and never really tested with a DVP bus.

This is troublesome, since we cannot adjust it at runtime based on other parameters (such as the number of bytes per pixel), and we can't support either framerates that have not been used by the various vendors, since we don't have the needed initialization sequence. We can however understand how the clock tree works, and then implement some functions to derive the various parameters from a given rate. And now that those parameters are calculated at runtime, we can remove them from the initialization sequence. The modes also gained a new parameter which is the clock that they are running at, from the register writes they were doing, so for now the switch to the new algorithm should be transparent.

By that reason, when writer finally releases write end of the semaphore __ldsem_wake_readers() does adjust sem->count with wrong value: sem->wait_readers * (LDSEM_ACTIVE_BIAS - LDSEM_WAIT_BIAS) I.e, if update comes with 1 missed wait_readers decrement, sem->count will be 0x100000001 which means that there is active reader and it'll make any further writer to fail in acquiring the semaphore. It looks like, this is a dead-code, because ldsem_down_read() is never called with timeout different than MAX_SCHEDULE_TIMEOUT, so it might be worth to delete timeout parameter and error path fall-back..

The codec however supports up to 192 kHz for playback. This patch drops the oversampling rate from 512 to 128, so that 192 kHz audio can be played back directly without downsampling. Ideally we should be using different oversampling rates for different sampling rates, but that's not possible without a platform-specific machine driver.

The clock rate for the module clocks is governed by their upstream audio PLL. The module clocks themselves only have a gate, and sometimes a divider or mux. Thus any rate changes need to be propagated upstream. Set the CLK_SET_RATE_PARENT flag for all audio module clocks to achieve this.

Until now we were using the closest clock rate possible with integer N-M factors. This resulted in audio playback being slightly slower than it should be. The vendor kernel gets around this (for newer SoCs) by using sigma-delta modulation to generate a fractional-N factor. As the PLL hardware is identical in most chips, we can back port the settings from the newer SoC, in this case the H3, onto the A33.

For this purpose, a dummy syscon node was introduced to let the driver access the register freely. Recently, the EMAC driver was tuned to get access to the register when the SRAM driver is registered (as used on the A64). As a result, it is no longer necessary to have a dummy syscon node for that purpose. Now that we have a proper system-control node for both the H3 and H5, we can get rid of that dummy syscon node and have the EMAC driver use the node corresponding to the proper SRAM driver (by switching the syscon label over to each dtsi). This way, we no longer have two separate nodes for the same register space.

A previous commit added a 1ms retry delay after multiple consecutive NAKed transactions using jiffies. On systems with a low timer interrupt frequency, this delay may be significantly longer than specified, resulting in misbehavior with some USB devices. This scenario was reached on a Raspberry Pi 3B with a Macally FDD-USB floppy drive (identified as 0424:0fdc Standard Microsystems Corp. Floppy, based on the USB97CFDC USB FDC). With the relay delay, the drive would be unable to mount a disk, replying with NAKs until the device was reset. Using ktime, the delta between starting the timer (in dwc2_hcd_qh_add) and the callback function can be determined. With the original delay implementation, this value was consistently approximately 12ms.

In practice this means that Thunderbolt connected devices are placed behind an IOMMU during the whole time it is connected (including during boot) making Thunderbolt security levels redundant. This is called Kernel DMA protection [1] by Microsoft. Some of these systems still have Thunderbolt security level set to "user" in order to support OS downgrade (the older version of the OS might not support IOMMU based DMA protection so connecting a device still relies on user approval). Export this information to userspace by introducing a new sysfs attribute (iommu_dma_protection). Based on it userspace tools can make more accurate decision whether or not authorize the connected device. In addition update Thunderbolt documentation regarding IOMMU based DMA protection.

ATS is used to accelerate DMA access as the device can cache translations locally so there is no need to do full translation on IOMMU side. However, as pointed out in [1] ATS can be used to bypass IOMMU based security completely by simply sending PCIe read/write transaction with AT (Address Translation) field set to "translated". To mitigate this modify the Intel IOMMU code so that it does not enable ATS for any device that is marked as being untrusted. In case this turns out to cause performance issues we may selectively allow ATS based on user decision but currently use big hammer and disable it completely to be on the safe side.

This means that during OS boot, before it enables IOMMU none of the connected devices can bypass DMA protection for instance by overwriting the data structures used by the IOMMU. The OS also treats this as a hint that the IOMMU should be enabled to prevent DMA attacks from possible malicious devices. A use of this flag is Kernel DMA protection for Thunderbolt [2] which in practice means that IOMMU should be enabled for PCIe devices connected to the Thunderbolt ports. With IOMMU enabled for these devices, all DMA operations are limited in the range reserved for it, thus the DMA attacks are prevented. All these devices are enumerated in the PCI/PCIe module and marked with an untrusted flag. This forces IOMMU to be enabled if DMA_CTRL_PLATFORM_OPT_IN_FLAG is set in DMAR ACPI table and there are PCIe devices marked as untrusted in the system. This can be turned off by adding "intel_iommu=off" in the kernel command line, if any problems are found.

An external Thunderbolt port is a convenient point to attach such a device. The OS may use IOMMU to defend against DMA attacks. Some BIOSes mark these externally facing root ports with this ACPI _DSD [1]: Name (_DSD, Package () { ToUUID ("efcc06cc-73ac-4bc3-bff0-76143807c389"), Package () { Package () {"ExternalFacingPort", 1}, Package () {"UID", 0 } } }) If we find such a root port, mark it and all its children as untrusted. The rest of the OS may use this information to enable DMA protection against malicious devices. For instance the device may be put behind an IOMMU to keep it from accessing memory outside of what the driver has allocated for it. While at it, add a comment on top of prp_guids array explaining the possible caveat resulting when these GUIDs are treated equivalent.

The layout of blob data is simply an array of "struct drm_mode_rect". Unlike plane src coordinates, damage clips are not in 16.16 fixed point. As plane src in framebuffer cannot be negative so are damage clips. In damage clip, x1/y1 are inclusive and x2/y2 are exclusive. This patch also exports the kernel internal drm_rect to userspace as drm_mode_rect. This is because "struct drm_clip_rect" is not sufficient to represent damage for current plane size. Driver which are interested in enabling FB_DAMAGE_CLIPS property for a plane should enable this property using drm_plane_enable_damage_clips. v2: - Input validation on damage clips against framebuffer size. - Doc update, other minor changes.

In the present code, __dwc3_prepare_one_trb() is called with a TRB which needs to be prepared for transfer. This __dwc3_prepare_one_trb() calls dwc3_calc_trbs_left() to determine total available TRBs and set IOC bit if the total available TRBs are zero. Since the present working TRB (which is passed as an argument to __dwc3_prepare_one_trb() ) doesn't yet have the HWO bit set before calling dwc3_calc_trbs_left(), there are chances that dwc3_calc_trbs_left() wrongly calculates this present working TRB as free(since the HWO bit is not yet set) and returns the total available TRBs as greater than zero (including the present working TRB). This could be a problem. This patch corrects the above mentioned problem in __dwc3_prepare_one_trb() by increementing the dep->trb_enqueue at the last (after preparing the TRB) instead of increementing at the start and setting the IOC bit only if the total available TRBs returned by dwc3_calc_trbs_left() is 1 . Since we are increementing the dep->trb_enqueue at the last, the present working TRB is also considered as available by dwc3_calc_trbs_left() and non zero value is returned . So, according to the modified logic, when the total available TRBs is equal to 1 that means the total available TRBs in the pool are 0.

The inclusion of a variable length packet header in URB packets mean that we must memcpy the frame data out to our destination 'manually'. This can result in data rates of up to 2 gigabits per second being processed.

Although not critical, we are currently missing a call to destroy the mutex on clean up paths, and we are due to extend the objects complexity in the near future. Facilitate easy management of a stream object by creating a pair of functions to handle creating and destroying the allocation. The new uvc_stream_delete() function also performs the missing mutex_destroy() operation. Previously a failed streaming object allocation would cause uvc_parse_streaming() to return -EINVAL, which is inappropriate. If the constructor failes, we will instead return -ENOMEM.

This included stripping the .altinstructions and .altinstr_replacement sections. Eventually, the stripping process reverted to "objdump -S" and no longer removed the aforementioned sections, but the comment remained. Keeping the .alt* sections at the end of the PT_LOAD segment is no longer necessary, but there's no harm in doing so and it's a helpful reminder that they don't need to be included in the final vDSO image, i.e. someone may want to take another stab at zapping/stripping the unneeded sections.

Part of that stripping process involved building a fake section table so as not to break userspace processes that parse the section table. Memory for the fake section table was reserved in the .rodata section so that vdso2c could simply copy the entire PT_LOAD segment into the userspace image after building the fake table. Eventually, the entire fake section table approach was dropped in favor of stripping the vdso "the old fashioned way", i.e. via objdump -S. But, the reservation in .rodata for the fake table was left behind. Remove the reserveration along with a few other related defines and section entries. Removing the fake section table placeholder zaps a whopping 0x340 bytes from the 64-bit vDSO image, which drops the current image's size to under 4k, i.e. reduces the effective size of the userspace vDSO mapping by a full page.

It works reasonably well, but the following happens : Once the limit is reached, TCP stack generates an [E]POLLOUT event for every incoming ACK packet. This causes a high number of context switches. This patch implements the strategy David Miller added in sock_def_write_space() : - If TCP socket has a notsent_lowat constraint of X bytes, allow sendmsg() to fill up to X bytes, but send [E]POLLOUT only if number of notsent bytes is below X/2 This considerably reduces TCP_NOTSENT_LOWAT overhead, while allowing to keep the pipe full.

However, the expired cache_head may be waiting for a reply from a previously submitted request. Such a cache_head has an increased refcounter and therefore it won't be freed after cache_put(freeme). Because the cache_head was removed from the hash it cannot be found during cache_clean() and can be leaked forever, together with stalled cache_request and other taken resources. In our case we noticed it because an entry in the export cache was holding a reference on a filesystem.

The first patch updates mlx5 ifc file. Next 3 patches enable modifying and querying verbs objects via the DEVX interface. To achieve that the core layer introduced the 'UVERBS_IDR_ANY_OBJECT' type to match any IDR object. Once it's used by some driver's method, the infrastructure skips checking for the IDR type and it becomes the driver handler responsibility. The DEVX methods of modify and query were changed to get any object type via the 'UVERBS_IDR_ANY_OBJECT' mechanism. The type checking is done per object as part of the driver code. The next 3 patches introduce more robust mechanism for controlling privileged DEVX commands. The responsibility to block/allow per command was moved to be done in the firmware based on the UID credentials that the driver reports upon user context creation. This enables more granularity per command based on the device security model and the user credentials. In addition, by introducing a valid range for 'general commands' we prevent the need to touch the driver's code any time that a new future command will be added. The last patch fixes the XRC verbs flow once a DEVX context is used. This is needed as XRCD is some shared kernel resource and as such a kernel UID (=0) should be used in its related resources. Thanks Yishai Hadas ----------------------------------- The top 6 patches are the mlx5-devx series, the remainder are from the mlx5-next tree as the mlx5-devx series depended on the mlx5-next mlx5_ifc file update. * mlx5-devx: (42 commits) IB/mlx5: Allow XRC usage via verbs in DEVX context IB/mlx5: Update the supported DEVX commands IB/mlx5: Enforce DEVX privilege by firmware IB/mlx5: Enable modify and query verbs objects via DEVX IB/core: Enable getting an object type from a given uobject IB/core: Introduce UVERBS_IDR_ANY_OBJECT net/mlx5: Update mlx5_ifc with DEVX UCTX capabilities bits RDMA/mlx5: Unfold modify RMP function RDMA/mlx5: Unfold create RMP function RDMA/mlx5: Initialize SRQ tables on mlx5_ib RDMA/mlx5: Update SRQ functions signatures to mlx5_ib format RDMA/mlx5: Use stages for callback to setup and release DEVX RDMA/mlx5: Remove SRQ signature global flag net/mlx5: Move SRQ functions to RDMA part net/mlx5: Remove references to local mlx5_core functions net/mlx5: Remove not-used lib/eq.h header file net/mlx5: Remove dead transobj code net/mlx5: Align SRQ licenses and copyright information net/mlx5: Debug print for forwarded async events net/mlx5: Forward SRQ resource events ...

This includes "get security state", "set passphrase", "unlock unit", "freeze lock", "secure erase", "overwrite", "overwrite query", "master passphrase enable/disable", and "master erase", . Since this adds several Intel definitions, move the relevant bits to their own header. These commands mutate physical data, but that manipulation is not cache coherent. The requirement to flush and invalidate caches makes these commands unsuitable to be called from userspace, so extra logic is added to detect and block these commands from being submitted via the ioctl command submission path. Lastly, the commands may contain sensitive key material that should not be dumped in a standard debug session. Update the nvdimm-command payload-dump facility to move security command payloads behind a default-off compile time switch.

Commit de92436ac40f ("dmaengine: bcm2835-dma: Use vchan_terminate_vdesc() instead of desc_free") amended the BCM2835 DMA driver with an implementation of ->device_synchronize(), which is a prerequisite for dmaengine_terminate_sync(). Thus, clients of the DMA driver (such as the BCM2835 SPI driver) may now be converted to the new API. It is generally desirable to use the _sync() variant except in atomic context. There is only a single occurrence where the BCM2835 SPI driver calls dmaengine_terminate_all() in atomic context and that is in bcm2835_spi_dma_done() (the RX DMA channel's callback) to terminate the TX DMA channel. The TX DMA channel doesn't have a callback (yet), hence it is safe to use the _async() variant there.

The CS register provides hints on their fill level: "Bit 19 RXR - RX FIFO needs Reading ([¾] full) 0 = RX FIFO is less than [¾] full (or not active TA = 0). 1 = RX FIFO is [¾] or more full. Cleared by reading sufficient data from the RX FIFO or setting TA to 0." "Bit 16 DONE - Transfer Done 0 = Transfer is in progress (or not active TA = 0). 1 = Transfer is complete. Cleared by writing more data to the TX FIFO or setting TA to 0." "If DONE is set [...], write up to 16 [dwords] to SPI_FIFO. [...] If RXR is set read 12 [dwords] data from SPI_FIFO." [Source: Pages 153, 154 and 158 of https://www.raspberrypi.org/app/uploads/2012/02/BCM2835-ARM-Peripherals.pdf Note: The spec is missing the "¾" character, presumably due to copy-pasting from a different charset. It also incorrectly refers to 16 and 12 "bytes" instead of 32-bit dwords.] In short, the RXR bit indicates that 48 bytes can be read and the DONE bit indicates 64 bytes can be written. Leverage this knowledge to read or write bytes blindly to the FIFO, without polling whether data can be read or free space is available to write. Moreover, when a transfer is starting, the TX FIFO is known to be empty, likewise allowing a blind write of 64 bytes. This cuts the number of bus accesses in half if the fill level is known. Also, the (posted) write accesses can be pipelined on the AXI bus since they are no longer interleaved with (non-posted) reads. bcm2835_spi_transfer_one_poll() switches to interrupt mode when a time limit is exceeded by calling bcm2835_spi_transfer_one_irq(). The TX FIFO may contain data in this case, but is known to be empty when the function is called from bcm2835_spi_transfer_one(). Hence only blindly fill the TX FIFO in the latter case but not the former.

This allowed the kernel to route the packet and also potentially generate an ICMP redirect. There are scenarios (e.g., "one-armed router") where packets are intentionally routed this way and are therefore not deemed as exceptions. In such scenarios the current method of trapping packets to the CPU is problematic, as it results in major packet loss. This patchset solves the problem by having the ASIC forward the packet, but also send a copy to the CPU, which gives the kernel the opportunity to generate required exceptions. To prevent the kernel from forwarding such packets again, the driver marks them with 'offload_l3_fwd_mark', which causes the kernel to consume them in ip{,6}_forward_finish(). Patch #1 renames 'offload_mr_fwd_mark' to 'offload_l3_fwd_mark'. When set, the field indicates that a packet was already forwarded in L3 (unicast / multicast) by a capable device. Patch #2 teaches the kernel to consume unicast packets that have 'offload_l3_fwd_mark' set. Patch #3 changes mlxsw to mirror loopbacked (iRIF == eRIF) packets, instead of trapping them. Patch #4 adds a test case for above mentioned scenario. ==================== Signed-off-by: David S.

Thus far, this trap was configured to send a sole copy of the packet to the CPU so that ICMP redirect packets could be potentially generated by the kernel. This is problematic as the CPU cannot forward packets at 3.2Tb/s and there are scenarios (e.g., "one-armed router") where iRIF == eRIF is not an exception. Solve this by changing the trap to send a copy of the packet to the CPU. To prevent the kernel from forwarding the packet again, it is marked with 'offload_l3_fwd_mark'. The trap is configured in a trap group of its own with a dedicated policer in order not to prevent packets trapped by other traps from reaching the CPU.

The field is used to prevent the kernel from forwarding a packet through a netdev through which the device has already forwarded the packet. Currently, no unicast packet is routed by both the device and the kernel, but this is about to change by subsequent patches and we need to be able to mark such packets, so that they will no be forwarded twice. Instead of adding yet another field to 'struct sk_buff', we can just rename 'offload_mr_fwd_mark' to 'offload_l3_fwd_mark', as a packet either has a multicast or a unicast destination IP.

As we then do not care about its contents, we can use one page for all, reducing our allocations and avoid complications by not assuming per-engine isolation. For later use, it simplifies engine initialisation (by removing the allocation that required struct_mutex!) and means that we can always rely on there being a scratch page. v2: Check that we allocated a large enough scratch for I830 w/a Fixes: 06e562e7f515 ("drm/i915/ringbuffer: Delay after EMIT_INVALIDATE for gen4/gen5") # v4.18.20 Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=108850 Signed-off-by: Chris Wilson Cc: Tvrtko Ursulin Cc: Mika Kuoppala Reviewed-by: Mika Kuoppala Link: https://patchwork.freedesktop.org/patch/msgid/20181204141522.13640-1-chris@chris-wilson.co.uk Cc: Joonas Lahtinen Cc: # v4.18.20+ commit 538a4ffea3f719ed8f853f78826e360aee5fe9d7 Author: Kuninori Morimoto Date: Tue Dec 4 08:02:43 2018 +0000 ASoC: rsnd: add missing TDM Split mode support for simple-card commit f69f452243e4e1 ("ASoC: rsnd: add TDM Split mode support") added TDM Split mode support for rsnd driver.

Also, it seems that our use of '-pie -shared' is contradictory, and thus ambiguous. In general, the way KASLR is wired up at the moment is highly tailored to how ld.bfd happens to implement (and conflate) PIE executables and shared libraries, so given the current effort to support other toolchains, let's fix some of these issues as well. - Drop the -pie linker argument and just leave -shared. In ld.bfd, the differences between them are unclear (except for the ELF type of the produced image [0]) but lld chokes on seeing both at the same time. - Rename the .rela output section to .rela.dyn, as is customary for shared libraries and PIE executables, so that it is not misidentified by readelf as a static relocation section (producing the warnings above). - Pass the -z notext and -z norelro options to explicitly instruct the linker to permit text relocations, and to omit the RELRO program header (which requires a certain section layout that we don't adhere to in the kernel). These are the defaults for current versions of ld.bfd. - Discard .eh_frame and .gnu.hash sections to avoid them from being emitted between .head.text and .text, screwing up the section layout. These changes only affect the ELF image, and produce the same binary image. [0] b9dce7f1ba01 ("arm64: kernel: force ET_DYN ELF type for ...")

This losing of applied workarounds has obvious negative effects and can even lead to hard system hangs (see the linked Bugzilla). Rather than just restoring this re-application, because we have also observed that it is not safe to just re-write all GT workarounds after engine resets (GPU might be live and weird hardware states can happen), we introduce a new class of per-engine workarounds and move only the affected GT workarounds over. Using the framework introduced in the previous patch, we therefore after engine reset, re-apply only the workarounds living in the affected MMIO address ranges. v2: * Move Wa_1406609255:icl to engine workarounds as well. * Rename API. (Chris Wilson) * Drop redundant IS_KABYLAKE. (Chris Wilson) * Re-order engine wa/ init so latest platforms are first.

The added data structure is a simple array of register, mask and value items, which is allocated on demand as workarounds are added to the list. This is a temporary implementation which later in the series gets fused with the existing per context workaround list handling. It is separated at this stage since the following patch fixes a bug which needs to be as easy to backport as possible. Also, since in the following patch we will be adding a new class of workarounds (per engine) which can be applied from interrupt context, we straight away make the provision for safe read-modify-write cycle. v2: * Change dev_priv to i915 along the init path. (Chris Wilson) * API rename. (Chris Wilson) v3: * Remove explicit list size tracking in favour of growing the allocation in power of two chunks. (Chris Wilson) v4: Chris Wilson: * Change wa_list_finish to early return. * Copy workarounds using the compiler for static checking. * Do not bother zeroing unused entries. * Re-order struct i915_wa_list. v5: * kmalloc_array. * Whitespace cleanup.

So it could invoke kernel_fpu_begin() right away. The 32bit version of arch_efi_call_virt_setup() and arch_efi_call_virt_teardown() does this already. The comment above *kernel_fpu*() claims that before invoking __kernel_fpu_begin() preemption should be disabled and that KVM is a good example of doing it. Well, KVM doesn't do that since commit f775b13eedee2 ("x86,kvm: move qemu/guest FPU switching out to vcpu_run") so it is not an example anymore. With EFI gone as the last user of __kernel_fpu_{begin|end}(), both can be made static and not exported anymore.

The system call table generation script is added in kernel/syscalls directory which contain the scripts to generate both uapi header file and system call table files. The syscall.tbl will be input for the scripts. syscall.tbl contains the list of available system calls along with system call number and corresponding entry point. Add a new system call in this architecture will be possible by adding new entry in the syscall.tbl file. Adding a new table entry consisting of: - System call number. - ABI. - System call name. - Entry point name. syscallhdr.sh and syscalltbl.sh will generate uapi header unistd_32.h and syscall_table.h files respectively. Both .sh files will parse the content syscall.tbl to generate the header and table files. unistd_32.h will be included by uapi/asm/unistd.h and syscall_table.h is included by kernel/syscall_table.S - the real system call table. ARM, s390 and x86 architecuture does have similar support. I leverage their implementation to come up with a generic solution.

We have to change the value of NR_syscalls, if we add or delete a system call. One of the patch in this patch series has a script which will generate a uapi header based on syscall- .tbl file. The syscall.tbl file contains the total number of system calls information. So we have two option to update NR_syscalls value. 1. Update NR_syscalls in asm/unistd.h manually by counting the no.of system calls. No need to up- date NR_syscalls until we either add a new sys- tem call or delete existing system call. 2. We can keep this feature it above mentioned sc- ript, that will count the number of syscalls and keep it in a generated file. In this case we don't need to explicitly update NR_syscalls in asm/unistd.h file. The 2nd option will be the recommended one. For that, I added the __NR_syscalls macro in uapi/asm/unistd.h along with NR_syscalls asm/unistd.h. The macro __NR- _syscalls also added for making the name convention same across all architecture. While __NR_syscalls isn't strictly part of the uapi, having it as part of the generated header to simplifies the implement- ation. We also need to enclose this macro with #ifdef __KERNEL__ to avoid side effects.

The 8xx offers hardware assistance which allows significant size reduction of the TLB handlers, hence also reduces the time spent in the handlers. However, using this HW assistance implies some constraints on the page table structure: - Regardless of the main page size used (4k or 16k), the level 1 table (PGD) contains 1024 entries and each PGD entry covers a 4Mbytes area which is managed by a level 2 table (PTE) containing also 1024 entries each describing a 4k page. - 16k pages require 4 identifical entries in the L2 table - 512k pages PTE have to be spread every 128 bytes in the L2 table - 8M pages PTE are at the address pointed by the L1 entry and each 8M page require 2 identical entries in the PGD. This patch modifies the TLB handlers to use HW assistance for 4K PAGES. Before that patch, the mean time spent in TLB miss handlers is: - ITLB miss: 80 ticks - DTLB miss: 62 ticks After that patch, the mean time spent in TLB miss handlers is: - ITLB miss: 72 ticks - DTLB miss: 54 ticks So the improvement is 10% for ITLB and 13% for DTLB misses Signed-off-by: Christophe Leroy Signed-off-by: Michael Ellerman commit 5af543be14cdad5d515631c5fe6984813fe0db70 Author: Christophe Leroy Date: Thu Nov 29 14:07:13 2018 +0000 powerpc/8xx: Temporarily disable 16k pages and hugepages In preparation of making use of hardware assistance in TLB handlers, this patch temporarily disables 16K pages and hugepages. The reason is that when using HW assistance in 4K pages mode, the linux model fit with the HW model for 4K pages and 8M pages. However for 16K pages and 512K mode some additional work is needed to get linux model fit with HW model. For the 8M pages, they will naturaly come back when we switch to HW assistance, without any additional handling. In order to keep the following patch smaller, the removal of the current special handling for 8M pages gets removed here as well. Therefore the 4K pages mode will be implemented first and without support for 512k hugepages. Then the 512k hugepages will be brought back. And the 16K pages will be implemented in the following step.

Preemption should be disabled because the per CPU variable may make no sense if there is a preemption (and a CPU switch) after it reads the per CPU data and when it is used. In this device driver specifically, it is not a problem, because this code just needs to have access to one lppaca struct, and it does not matter if it is the current per CPU lppaca struct or not (i.e. when there is a preemption and a CPU migration). That said, the most appropriate fix seems to be related to avoiding the debug_smp_processor_id() call at get_paca(), instead of calling preempt_disable() before get_paca().

If there is a crash while devtree_lock is being held, then xmon tries to get the lock but spins forever and never get into the interactive debugger, as in the following case: int *ptr = NULL; raw_spin_lock_irqsave(&devtree_lock, flags); *ptr = 0xdeadbeef; This patch avoids calling rtas_token(), thus trying to get the same lock, at crash time. This new mechanism proposes getting the token at initialization time (xmon_init()) and just consuming it at crash time. This would allow xmon to be possible invoked independent of devtree_lock being held or not.

The handling of revoke tables as well as cleaning of t_reserved_list, and checkpoint lists does not need j_state_lock for anything. It is only needed to prevent new handles from joining the transaction. Generally T_LOCKED transaction state prevents new handles from joining the transaction - except for reserved handles which have to allowed to join while we wait for other handles to complete. To prevent reserved handles from joining the transaction while cleaning up lists, add new transaction state T_SWITCH and watch for it when starting reserved handles.

While this appears to work, it is does not seem like the right thing to do and could lead to future bugs so lets avoid that. It also prevents misleading prints in the logs which claim the buffer is valid. I got something like: found existing buffer, size 0, start 0 When I was expecting: no valid data in buffer (sig = ...) This bails out early (and reports with pr_debug()), since it's an acceptable state.

So lets remove it from the argument list. (2) remove max argument from ramoops_get_next_prz() Looking at the code flow, the 'max' checks are already being done on the prz passed to ramoops_get_next_prz(). Lets remove it to simplify this function and reduce its arguments. (3) further reduce ramoops_get_next_prz() arguments by passing record Both the id and type fields of a pstore_record are set by ramoops_get_next_prz(). So we can just pass a pointer to the pstore_record instead of passing individual elements. This results in cleaner more readable code and fewer lines. In addition lets also remove the 'update' argument since we can detect that. Changes are squashed into a single patch to reduce fixup conflicts.

This saves the type in the PRZ which will be useful in later patches. Instead of having an explicit PSTORE_TYPE_UNKNOWN, just use ..._MAX. This includes removing the now redundant filename templates which can use a single format string. Also, there's no reason to limit the "is it still compressed?" test to only PSTORE_TYPE_DMESG when building the pstorefs filename. Records are zero-initialized, so a backend would need to have explicitly set compressed=1.

Release of its last reference triggers a completion notification. The TCP stack in tcp_sendmsg_locked holds an extra ref independent of the skbs, because it can build, send and free skbs within its loop, possibly reaching refcount zero and freeing the ubuf_info too soon. The UDP stack currently also takes this extra ref, but does not need it as all skbs are sent after return from __ip(6)_append_data. Avoid the extra refcount_inc and refcount_dec_and_test, and generally the sock_zerocopy_put in the common path, by passing the initial reference to the first skb. This approach is taken instead of initializing the refcount to 0, as that would generate error "refcount_t: increment on 0" on the next skb_zcopy_set.

To support these, we store a unique NULLS_MARKER at the end of each chain, and when a search fails to find a match, we check if the NULLS marker found was the expected one. If not, the search may not have examined all objects in the target bucket, so it is repeated. The unique NULLS_MARKER is derived from the address of the head of the chain. As this cannot be derived at load-time the static rhnull in rht_bucket_nested() needs to be initialised at run time. Any caller of a lookup function must still be prepared for the possibility that the object returned is in a different table - it might have been there for some time. Note that this does NOT provide support for other uses of NULLS_MARKERs such as allocating with SLAB_TYPESAFE_BY_RCU or changing the key of an object and re-inserting it in the same table. These could only be done safely if new objects were inserted at the *start* of a hash chain, and that is not currently the case. Signed-off-by: NeilBrown Acked-by: Herbert Xu Signed-off-by: David S.

Therefore network drivers have to do this in some kind of glue code. I think this can be avoided. Getting EEE parameters: When not advertising any EEE mode, we can't consider EEE to be enabled. Therefore interpret "EEE enabled" as "we advertise at least one EEE mode". It's similar with "EEE active": interpret it as "EEE modes advertised by both link partner have at least one mode in common". Setting EEE parameters: If eee_enabled isn't set, don't advertise any EEE mode and restart aneg if needed to switch off EEE. If eee_enabled is set and data->advertised is empty (e.g. because EEE was disabled), advertise everything we support as default. This way EEE can easily switched on/off by doing ethtool --set-eee eee on/off, w/o any additional parameters. The changes to both functions shouldn't break any existing user. Once the changes have been applied, at least some users can be simplified. Signed-off-by: Heiner Kallweit Signed-off-by: David S.

The workaround is to enable *udp_l3mdev_accept* sysctl, but this breaks isolation between overlay and underlay: packets sent from blue or red by e.g. a guest VM will be accepted by the socket, allowing injection of VXLAN packets from the overlay. This patch series fixes the issues describe above by allowing VXLAN socket to be bound to a specific VRF device therefore looking up in the correct table. ==================== Signed-off-by: David S.

This patch binds the underlying UDP tunnel socket to the l3mdev of the lower device of the VXLAN device. This will listen in the proper VRF and output traffic from said l3mdev, matching l3mdev routing rules and looking up the correct routing table. When the VXLAN device does not have a lower device, or the lower device is in the default VRF, the socket will not be bound to any interface, keeping the previous behaviour. The underlay l3mdev is deduced from the VXLAN lower device (IFLA_VXLAN_LINK). +----------+ +---------+ | | | | | vrf-blue | | vrf-red | | | | | +----+-----+ +----+----+ | | | | +----+-----+ +----+----+ | | | | | br-blue | | br-red | | | | | +----+-----+ +---+-+---+ | | | | +-----+ +-----+ | | | +----+-----+ +------+----+ +----+----+ | | lower device | | | | | eth0 | <- - - - - - - | vxlan-red | | tap-red | (... more taps) | | | | | | +----------+ +-----------+ +---------+ Signed-off-by: Alexis Bauvin Reviewed-by: Amine Kherbouche Reviewed-by: David Ahern Tested-by: Amine Kherbouche Signed-off-by: David S.

Currently this option is not controlled by the user and the driver decides from where to load the firmware image. 'fw_load_policy' gives the ability to control this option which allows the user to choose between different loading policies supported by the driver. This parameter can be useful while testing and/or debugging the device. For example, testing a firmware bug fix.

That makes lspci & co. produce gibberish. To fix that let's try to implement actual runtime pm hooks and inform the pci core that the device always goes to D3cold. That will cause the pci core to resume the device before attempting config space access. This introduces another annoyance though. We get the following error every time we try to resume the device: intel_atomisp2_pm 0000:00:03.0: Refused to change power state, currently in D3 The reason being that the pci core tries to put the device back into D0 via the standard PCI PM mechanism before calling the driver resume hook. To fix this properly we'd need to infiltrate the platform pm hooks (could turn ugly real fast), or use pm domains (which don't seem to exist on x86), or some extra early resume hook for the driver (which doesn't exist either). So maybe we just choose to live with the error?

Except for a few clock sources shared between two domains, such as the System Oscillator clock, the Slow IRC (SIRC), and and the Fast IRC clock (FIRCLK), clock sources and clock management are separated and contained within each domain. M4 clock management consists of SCG0, PCC0, PCC1, and CMC0 modules. A7 clock management consists of SCG1, PCC2, PCC3, and CMC1 modules. This driver only adds clock support in A7 domain. Note that most clocks required to be operated when gated, e.g. pll, pfd, pcc. And more special cases that scs/ddr/nic mux selecting different clock source requires that clock to be enabled first, then we need set CLK_OPS_PARENT_ENABLE flag for them properly.

This can be used to support frac dividers like below: Divider output clock = Divider input clock x [(frac +1) / (div +1)] where frac/div in register is: 000b - Divide by 1. 001b - Divide by 2. 010b - Divide by 3.

Dong Date: Wed Nov 14 13:01:35 2018 +0000 clk: imx: add gatable clock divider support For dividers with zero indicating clock is disabled, instead of giving a warning each time like "clkx: Zero divisor and CLK_DIVIDER_ALLOW_ZERO not set" in exist code, we'd like to introduce enable/disable function for it. e.g. 000b - Clock disabled 001b - Divide by 1 010b - Divide by 2 ... Set rate when the clk is disabled will cache the rate request and only when the clk is enabled will the driver actually program the hardware to have the requested divider value. Similarly, when the clk is disabled we'll write a 0 there, but when the clk is enabled we'll restore whatever rate (divider) was chosen last. It does mean that recalc rate will be sort of odd, because when the clk is off it will return 0, and when the clk is on it will return the right rate. So to make things work, we'll need to return the cached rate in recalc rate when the clk is off and read the hardware when the clk is on. NOTE for the default off divider, the recalc rate will still return 0 as there's still no proper preset rate. Enable such divider will give user a reminder error message.

[0] This is because of the order in which things are torn down. If there are no streams active during a USB disconnect: - uvc_disconnect() is invoked via device_del() through the bus notifier mechanism. - this calls uvc_unregister_video(). - uvc_unregister_video() unregisters the video device for each stream, - because there are no streams open, it calls uvc_delete() - uvc_delete() calls uvc_status_cleanup(), which cleans up the status input device. - uvc_delete() calls media_device_unregister(), which cleans up the media device - uvc_delete(), uvc_unregister_video() and uvc_disconnect() all return, and we end up back in device_del(). - device_del() then cleans up the sysfs folder for the camera with dpm_sysfs_remove(). Because uvc_status_cleanup() and media_device_unregister() have already been called, this all works nicely. If, on the other hand, there *are* streams active during a USB disconnect: - uvc_disconnect() is invoked - this calls uvc_unregister_video() - uvc_unregister_video() unregisters the video device for each stream, - uvc_unregister_video() and uvc_disconnect() return, and we end up back in device_del(). - device_del() then cleans up the sysfs folder for the camera with dpm_sysfs_remove(). Because the status input device and the media device are children of the USB device, this also deletes their sysfs folders. - Sometime later, the final stream is closed, invoking uvc_release(). - uvc_release() calls uvc_delete() - uvc_delete() calls uvc_status_cleanup(), which cleans up the status input device. Because the sysfs directory has already been removed, this causes a WARNing. - uvc_delete() calls media_device_unregister(), which cleans up the media device. Because the sysfs directory has already been removed, this causes another WARNing. To fix this, we need to make sure the devices are always unregistered before the end of uvc_disconnect(). To this, move the unregistration into the disconnect path: - split uvc_status_cleanup() into two parts, one on disconnect that unregisters and one on delete that frees. - move v4l2_device_unregister() and media_device_unregister() into the disconnect path.

It accesses the "xstate_comp_offsets" variable for the actual offset and it was introduced in commit 7496d6458fe32 ("Define kernel API to get address of each state in xsave area") Based on the code (back then and now): - xstate_offsets holds the standard offset. - if compacted mode is not supported then xstate_comp_offsets gets the xstate_offsets copied. - if compacted mode is supported then xstate_comp_offsets will hold the offset for the compacted buffer. Based on that the function works for compacted buffers as long as the CPU supports it and this what we care about. Remove the "Note:" which is not accurate.

Along the way this consolidates all the copy_to/from_user into a small set of safe buffer accessor functions tailored to the usage here. These accessors use the new dispatcher-controlled calling convention for ucore data, and support a placement of the response that does not rely on the cmd.response value. Overall this brings in in strong bounds checking to all the write() handlers and consistent enforcement of the zero-fill/zero-check methodology for buffer extension. The end result is a significant complexity reduction for all of the handlers and creates a high degree of uniformity between the write, write_ex, and ioctl handlers and dispatch flow.

Note that we cannot simply keep the DDI clock gated when the port will be only used in DSI mode: it must be gated/ungated at a specific spot in the DSI enable/disable sequence. Ensure the above for all ports of a DSI encoder, also adding a sanity check that we haven't registered another encoder using the same port (VBT should never allow this to happen).

This allows removal of a bunch of boilerplate code from the functions. Additionally, the ICL DSI encoder needs to do the clock gating and ungating slightly differently, and this allows its own handling in a clean fashion.

That changed when we forked out support for the latter into the export.h file. This means we should be able to reduce the usage of module.h in code that is obj-y Makefile or bool Kconfig. The advantage in removing such instances is that module.h itself sources about 15 other headers; adding significantly to what we feed cpp, and it can obscure what headers we are effectively using. Since module.h might have been the implicit source for init.h (for __init) and for export.h (for EXPORT_SYMBOL) we consider each instance for the presence of either and replace as needed.

The final video clocks are: - cts_enct - cts_encl - cts_encp - cts_enci - cts_vdac0 - hdmi_tx_pixel - hdmi_sys Add multiple clocks in between which are needed to implement these clocks: - Opposed to GXBB there is no pre-multiplier for the PLL input. The assumption here is that the multiplier is required to achieve the HDMI 2.0 clock rates (which are up to twice the rate of the HDMI 1.4 rates). - The main PLL is called "HDMI PLL" or "HPLL" in the datasheet. Rename our existing "vid_pll_dco" to "hdmi_pll_dco". The actual VID_PLL clock also exists further down the tree. - Rename the existing "vid_pll" clock (which is the OD divider at HHI_VID_PLL_CNTL[17:16]) to "hdmi_pll_lvds_out" to match the naming from the datasheet. - Add the second OD divider called "hdmi_pll_hdmi_out" at HHI_VID_PLL_CNTL[19:18]. - Add the "vid_pll_in_sel" which can choose between "hdmi_pll_dco" and another parent. However, the second parent is not use on Amlogic's 3.10 kernel for HDMI or CVBS output so just leave a TODO in the code. - Add the "vid_pll_in_en" which is located after "vid_pll_in_sel" according to the datasheet. - Add "vid_pll_pre_div" which is used for divide-by-5 and divide-by-6 in Amlogic's 3.10 kernel sources. - Add "vid_pll_post_div" which divides the output of "vid_pll_pre_div" further down. The Amlogic 3.10 kernel configures this as divide-by-2 with "vid_pll_pre_div" being configured as divide-by-5 to achieve a total divider of 10. - Add the real "vid_pll" clock which selects between "vid_pll_pre_div", "vid_pll_post_div" and a third "vid_pll_pre_div_mult7_div2" (which is "vid_pll_pre_div" divided by 3.5). The latter is not supported yet because it's not used in Amlogic's 3.10 kernel. The "vid_pll" clock rate can also be measured by clkmsr to check whether this implementation is correct. - Add "vid_pll_final_div" which is a post-divider for "vid_pll" and it's used as input for "vclk" and "vclk2" - Add the two symmetric "vclk" and "vclk" clock trees, each with a divide-by-1, divide-by-2, divide-by-4, divide-by-6 and divide-by-12 clock and a divider for each clock. - Add the "cts_enct", "cts_encp" and "hdmi_tx_pixel" clocks which each have their own gate and can select between any of the five "vclk" dividers. - Add the "cts_encl" and "cts_vdac0" clocks which each have their own gate and can select between any of the five "vclk2" dividers. The "hdmi_sys" clock is a different than these video clocks. It takes "xtal" as input (there are three more but unknown parents). Add this clock as well as it's used by the HDMI controller. Amlogic's 3.10 kernel always configures this as "xtal divided by 1", so we can ignore the other parents for now. This was tested on Meson8b and Meson8m2 boards by comparing the common clock framework output with the clock measurer output. The following video modes were first set in u-boot (by running "video dev open $mode") before booting Linux: 4K2K30HZ (only supported by Meson8m2, not tested on Meson8b): - vid_pll: 297000000Hz - cts_encp: 297000000Hz - hdmi_tx_pixel: 297000000Hz 1080P: - vid_pll: 148500000Hz - cts_encp: 148500000Hz - hdmi_tx_pixel: 148500000Hz 720P: - vid_pll: 148500000Hz - cts_encp: 148500000Hz - hdmi_tx_pixel: 74250000Hz 480P: - vid_pll: 216000000Hz - cts_encp: 54000000Hz - hdmi_tx_pixel: 27000000Hz Signed-off-by: Martin Blumenstingl Signed-off-by: Neil Armstrong Link: https://lkml.kernel.org/r/20181202214220.7715-4-martin.blumenstingl@googlemail.com commit 007f3da7d38ac7eb71fb092e43354dbf2e7b5109 Author: Martin Blumenstingl Date: Sun Dec 2 22:42:19 2018 +0100 clk: meson: meson8b: add the fractional divider for vid_pll_dco This "vid_pll_dco" (which should be named HDMI_PLL or - as the datasheet calls it - HPLL) has a 12-bit wide fractional parameter at HHI_VID_PLL_CNTL2[11:0].

This results in an incorrect calculation of the rate of this PLL because the value seen by the kernel is double the actual N (divider) value.

To make it easy by keeping a script and which will generate the uapi header and syscall table file. This change will also help to unify the implemen- tation across all architectures. The system call table generation script is added in kernel/syscalls directory which contain the scripts to generate both uapi header file and system call table files. The syscall.tbl will be input for the scripts. syscall.tbl contains the list of available system calls along with system call number and corresponding entry point. Add a new system call in this architecture will be possible by adding new entry in the syscall.tbl file. Adding a new table entry consisting of: - System call number. - ABI. - System call name. - Entry point name. syscallhdr.sh and syscalltbl.sh will generate uapi header unistd_32.h and syscall_table.h files respectively. Both .sh files will parse the content syscall.tbl to generate the header and table files. unistd_32.h will be included by uapi/asm/unistd.h and syscall_table.h is included by kernel/syscall.c - the real system call table. ARM, s390 and x86 architecuture does have similar support. I leverage their implementation to come up with a generic solution.

We have to change the value of __NR_syscall_count, if we add or delete a system call. One of the patch in this patch series has a script which will generate a uapi header based on syscall.tbl file. The syscall.tbl file contains the total number of system calls information. So we have two option to update __NR- _syscall_count value. 1. Update __NR_syscall_count in asm/unistd.h manually by counting the no.of system calls. No need to update __NR- _syscall_count until we either add a new system call or delete existing system call. 2. We can keep this feature it above mentioned script, that will count the number of syscalls and keep it in a generated file. In this case we don't need to expli- citly update __NR_syscall_count in asm/unistd.h file. The 2nd option will be the recommended one. For that, I added the __NR_syscalls macro in uapi/asm/unistd.h. The macro __NR_syscalls also added for making the name convention same across all architecture. While __NR_syscalls isn't strictly part of the uapi, having it as part of the generated header to simplifies the implementation. We also need to enclose this macro with #ifdef __KERNEL__ to avoid side effects.

A hardware designer might say "the 1.5V rail is connected to the VCCP pin" leaving the software designer none the wiser as to which of the sysfs entries should be associated with the label "1.5V". Try to bridge the gap by documenting the mapping of sysfs entries to the corresponding pins. This should allow someone to create a configuration file or other mapping without needing to dive into the code and ADT datasheets.

When GPIOR3 is high, it consumes battery and impacts the battery life. So it is left for user space to toggle the GPIO when trying to read the voltage.

The defined limit is 0.83Mhz instead of 2Mhz, which is the chip's max frequency as specified in the datasheet, because, as also specified in the datasheet, a 600ns delay is expected between the application of a logic LO to CS and the application of SCLK. Since the delay is not implemented in the spi code, to satisfy it, SCLK's period should be at most 2 * 600ns, so the max frequency should be 1 / (2 * 6e-7), which gives roughly 830000Hz.

'endef' directive is useful to confine a series of shell commands into a single macro: define foo [action1] [action2] [action3] endif Each action is executed in a separate subshell. However, rule_cc_o_c and rule_as_o_S in scripts/Makefile.build are written as follows (with a trailing semicolon in each cmd_*): define rule_cc_o_c [action1] ; \ [action2] ; \ [action3] ; endef All shell commands are concatenated with '; \' so that it looks like a single command from the Makefile point of view. This does not exploit the benefits of 'define' ... 'endef' form because a single shell command can be more simply written, like this: rule_cc_o_c = \ [action1] ; \ [action2] ; \ [action3] ; I guess the intention for the command concatenation was to let the '@set -e' in if_changed_rule cover all the commands. We can improve the readability by moving '@set -e' to the 'cmd' macro. The combo of $(call echo-cmd,*) $(cmd_*) in rule_cc_o_c and rule_as_o_S have been replaced with $(call cmd,*). The trailing back-slashes have been removed. Here is a note about the performance: the commands in rule_cc_o_c and rule_as_o_S were previously executed all together in a single subshell, but now each line in a separate subshell. This means Make will spawn extra subshells [1]. I measured the build performance for x86_64_defconfig + CONFIG_MODVERSIONS + CONFIG_TRIM_UNUSED_KSYMS and I saw slight performance regression, but I believe code readability and maintainability wins. [1] Precisely, GNU Make may optimize this by executing the command directly instead of forking a subshell, if no shell special characters are found in the command line and omitting the subshell will not change the behavior.

Currently, CONFIG_TRIM_UNUSED_KSYMS works with a tricky gimmick; possibly exported symbols are detected by letting $(CPP) replace EXPORT_SYMBOL* with a special string '=== __KSYM_*===', which is post-processed by sed, and passed to fixdep. The extra preprocessing is costly, and hacking cmd_and_fixdep is ugly. I came up with a new way to find exported symbols; insert a dummy symbol __ksym_marker_* to each potentially exported symbol. Those dummy symbols are picked up by $(NM), post-processed by sed, then appended to .*.cmd files. I collected the post-process part to a new shell script scripts/gen_ksymdeps.sh for readability. The dummy symbols are put into the .discard.* section so that the linker script rips them off the final vmlinux or modules. A nice side-effect is building with CONFIG_TRIM_UNUSED_KSYMS will be much faster.

This is a very safe way to avoid corrupted .*.cmd files. The if_changed_dep has carried this safety mechanism since it was added in 2002. If fixdep fails for some reasons or a user terminates the build while fixdep is running, the incomplete output from the fixdep could be troublesome. This is my insight about some bad scenarios: [1] If the compiler succeeds to generate *.o file, but fixdep fails to write necessary dependencies to .*.cmd file, Make will miss to rebuild the object when headers or CONFIG options are changed. In this case, fixdep should not generate .*.cmd file at all so that 'arg-check' will surely trigger the rebuild of the object. [2] A partially constructed .*.cmd file may not be a syntactically correct makefile. The next time Make runs, it would include it, then fail to parse it. Once this happens, 'make clean' is be the only way to fix it. In fact, [1] is no longer a problem since commit 9c2af1c7377a ("kbuild: add .DELETE_ON_ERROR special target"). Make deletes a target file on any failure in its recipe. Because fixdep is a part of the recipe of *.o target, if it fails, the *.o is deleted anyway. However, I am a bit worried about the slight possibility of [2]. So, here is a solution.

The serial driver code idiom triggering the warning is standard Linux serial driver practice that has a specific whitelist inclusion in modpost.c. I'm neither a modpost nor an ELF expert, but naively, it doesn't seem useful for modpost to report section mismatch warnings caused by ELF local symbols by default. Local symbols have compiler-generated names, and thus bypass modpost's whitelisting algorithm, which relies on the presence of a non-autogenerated symbol name. This increases the likelihood that false positive warnings will be generated (as in the above case). Thus, disable section mismatch reporting on ELF local symbols. The rationale here is similar to that of commit 2e3a10a1551d ("ARM: avoid ARM binutils leaking ELF local symbols") and of similar code already present in modpost.c: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/scripts/mod/modpost.c?h=v4.19-rc4&id=7876320f88802b22d4e2daf7eb027dd14175a0f8#n1256 This third version of the patch implements a suggestion from Masahiro Yamada to restructure the code as an additional pattern matching step inside secref_whitelist(), and further improves the patch description.

When we have parallel attempt to connect to same address:port pair, its likely that both cores end up computing the same "available" port, as both use same starting port, and newly used ports won't become visible to other cores until the conntrack gets confirmed later. One of the cores then has to drop the packet at insertion time because the chosen new tuple turns out to be in use after all. Lets simplify this: remove port rover and use a pseudo-random starting point. Note that this doesn't make netfilter default to 'fully random' mode; the 'rover' was only used if NAT could not reuse source port as-is.

Perhaps we can eventually try to (carefully) modify each test case which has this problem to not use unaligned accesses but: 1) That is delicate work. 2) The changes might not fully respect the original intention of the testcase. 3) In some cases, such a transformation might not even be feasible at all. So add an "any alignment" flag to tell the verifier to forcefully disable it's alignment checks completely. test_verifier.c is then annotated to use this flag when necessary. The presence of the flag in each test case is good documentation to anyone who wants to actually tackle the job of eliminating the unaligned memory accesses in the test cases. I've also seen several weird things in test cases, like trying to access __skb->mark in a packet buffer. This gets rid of 104 test_verifier.c failures on sparc64. Changes since v1: 1) Explain the new BPF_PROG_LOAD flag in easier to understand terms. Suggested by Alexei. 2) Make bpf_verify_program() just take a __u32 prog_flags instead of just accumulating boolean arguments over and over. Also suggested by Alexei. Changes since RFC: 1) Only the admin can allow the relaxation of alignment restrictions on inefficient unaligned access architectures. 2) Use F_NEEDS_EFFICIENT_UNALIGNED_ACCESS instead of making a new flag. 3) Annotate in the output, when we have a test case that the verifier accepted but we did not try to execute because we are on an inefficient unaligned access platform. Maybe with some arch machinery we can avoid this in the future. Signed-off-by: David S.

On inefficient unaligned access architectures do not try to run such programs, instead mark the test case as passing but annotate the result similarly to how it is done now in the presence of this flag.

Often we want to write tests cases that check things like bad context offset accesses. And one way to do this is to use an odd offset on, for example, a 32-bit load. This unfortunately triggers the alignment checks first on platforms that do not set CONFIG_EFFICIENT_UNALIGNED_ACCESS. So the test case see the alignment failure rather than what it was testing for. It is often not completely possible to respect the original intention of the test, or even test the same exact thing, while solving the alignment issue. Another option could have been to check the alignment after the context and other validations are performed by the verifier, but that is a non-trivial change to the verifier. Signed-off-by: David S.

This patch extends mlxsw to also support VLAN-aware bridges. The patch is similar in nature to mentioned commit, but there is one major difference. With VLAN-aware bridges, the VxLAN device's VNI is mapped to the VLAN that is configured as PVID and egress untagged on the bridge port. Therefore, the driver is extended to listen to VLAN configuration on VxLAN devices of interest and enable / disable NVE encapsulation on the corresponding 802.1Q FIDs. To prevent ambiguity, the driver makes sure that a given VLAN is not configured as PVID and egress untagged on multiple VxLAN devices.

Currently, the FID is simply resolved according to the ifindex of the bridge device to which the VxLAN device is enslaved. This works because only VLAN-unaware bridges are supported. With VLAN-aware bridges the FID would need to be resolved based on the VLAN to which the VNI is mapped to. Add the VLAN ID to the argument list of the function.

The function needs to resolve the FID that corresponds to the VxLAN device and disable NVE encapsulation on it. Instead of looking up the FID differently for VLAN-aware and VLAN-unaware bridges, we can always use the VxLAN's device VNI.

We do this for every IO, so the cost adds up. Shift a bit of the cost to the slow path, when we actually have waiters. Wrap prepare_to_wait_exclusive() and finish_wait(), so we can maintain an internal count of how many are currently active. Then we can simply check this count in sbq_wake_ptr() and not have to loop if we don't have any sleepers. Convert the two users of sbitmap with waiting, blk-mq-tag and iSCSI.

Even though we spread the bits out and maintain a hint cache, one particular bit allocated will end up being cleared in the exact same spot. This introduces batched clearing of bits. Instead of clearing a given bit, the same bit is set in a cleared/free mask instead. If we fail allocating a bit from a given word, then we check the free mask, and batch move those cleared bits at that time. This trades 64 atomic bitops for 2 cmpxchg(). In a threaded poll test case, half the overhead of getting and clearing tags is removed with this change. On another poll test case with a single thread, performance is unchanged.

When fill level reaches maximum, the device stops accepting all doorbells from that PF until a recovery procedure has taken place. Doorbell Overflow Recovery The recovery procedure basically means resending the last doorbell for every doorbelling entity. A doorbelling entity is anything which may send doorbells: L2 tx ring, rdma sq/rq/cq, light l2, vf l2 tx ring, spq, etc. This relies on the design assumption that all doorbells are aggregative, so last doorbell carries the information of all previous doorbells. APIs All doorbelling entities need to register with the mechanism before sending doorbells. The registration entails providing the doorbell address the entity would be using, and a virtual address where last doorbell data can be found. Typically fastpath structures already have this construct. Executing the recovery procedure Handling the attentions, iterating over all the registered entities and resending their doorbells, is all handled within qed core module. Relevance All doorbelling entities in all protocols need to register with the mechanism, via the new APIs. Technically this is quite simple (just call the API). Some protocol fastpath implementation may not have the doorbell data stored anywhere (compute it from scratch every time) and will have to add such a place. This is rare and is also better practice (save some cycles on the fastpath). Performance Penalty No performance penalty should incur as a result of this feature. If anything performance can improve by avoiding recalcualtion of doorbell data everytime doorbell is sent (in some flows). Add the database used to register doorbelling entities, and APIs for adding and deleting entries, and logic for traversing the database and doorbelling once on behalf of all entities. ==================== Signed-off-by: David S.

First patch refactors away a somewhat surprising if (1) code block. Reindentation will most likely cause cherry-pick problems but OTOH rtnl_newlink() doesn't seem to be changed often, so perhaps we can risk it in the name of cleaner code? Second patch fixes the warning in simplest possible way.

Fix the warning by allocating attributes with kmalloc() in a wrapper and passing it down to rtnl_newlink(), avoiding complexities on error paths. Alternatively we could kmalloc() some structure within rtnl_newlink(), slave attributes look like a good candidate. In practice it adds to already rather high complexity and length of the function.

Fourth patch is attempting coalescing when a new packet must be added to the backlog queue. Cooking bigger skbs helps to keep backlog list smaller and speeds its handling when user thread finally releases the socket lock. v3: Neal/Yuchung feedback addressed : Do not aggregate if any skb has URG bit set. Do not aggregate if the skbs have different ECE/CWR bits v2: added feedback from Neal : tcp: take care of compressed acks in tcp_add_reno_sack() added : tcp: hint compiler about sack flows added : tcp: make tcp_space() aware of socket backlog ==================== Signed-off-by: David S.

This patch balances work done from user thread and softirq, to give more chances to __release_sock() to complete its work before new packets are added the the backlog. This also helps if we receive many ACK packets, since GRO does not aggregate them. This patch brings ~60% throughput increase on a receiver without GRO, but the spectacular gain is really on 1000x release_sock() latency reduction I have measured.

This patch adds the corresponding exit trace events that will bound the reception such that all events occurring between the entry and the exit can be considered as part of the reception context. This greatly helps for dependency and root cause analyses. Without this, it is not possible with tracepoint instrumentation to determine whether a sched_wakeup event following a netif_receive_skb event is the result of the packet reception or a simple coincidence after further processing by the thread. It is possible using other mechanisms like kretprobes, but considering the "entry" points are already present, it would be good to add the matching exit events. In addition to linking packets with wakeups, the entry/exit event pair can also be used to perform network stack latency analyses.

For now we only run the queue 1 job deep, and don't have any hang recovery (though I don't think we should need it, with TFU).

The aux transaction was failing because the busy bit for the given gpio pin was always set. The busy bit was alway set because the programming sequence to read, modify and write busy bit was not atomic. Due to which when multiple threads are trying to modify the busy bits for their gpio pins in the same integer variable sometimes the busy bits integer variable is written with old data causing failure. [how] Instead of using individual bits to track gpio pins and grouping them to integers, one byte will be allcoated for each gpio pin. Now whenever a gpio pin needs to be set to mark being used, only writing a value of one to that byte is sufficient, other bytes are not impacted. Also no need to have atomicity with bytes unlike with bits.

Currently, a lock can block pending requests, but all pending requests are equal. If lots of pending requests are mutually exclusive, this means they will all be woken up and all but one will fail. This can hurt performance. So we will allow pending requests to block other requests. Only the first request will be woken, and it will wake the others. This patch doesn't implement this fully, but prepares the way. - It acknowledges that a request might be blocking other requests, and when the request is converted to a lock, those blocked requests are moved across. - When a request is requeued or discarded, all blocked requests are woken. - When deadlock-detection looks for the lock which blocks a given request, we follow the chain of ->fl_blocker all the way to the top.

For the async IO O_DIRECT case, we can't use the simple DIO variants, so we use __blkdev_direct_IO(). It always grabs an extra reference to the bio after allocation, which means we then enter the slower path of actually having to do atomic_inc/dec on the count. We don't need to do that for the async case, unless we end up going multi-bio, in which case we're already doing huge amounts of IO. For the smaller IO case (< BIO_MAX_PAGES), we can do without the extra ref. Based on an earlier patch (and commit log) from Jens Axboe.

This is necessary so that the core ftrace code can identify the specific instrumentation site. Since the instrumented function will be a BL, the address of the instrumented function is LR - 4 at entry to the ftrace code. This fixup is applied in the mcount_get_pc and mcount_get_pc0 helpers, which acquire the PC of the instrumented function. The mcount_get_lr helper is used to acquire the LR of the instrumented function, whose value does not require this adjustment, and cannot be adjusted to anything meaningful. No adjustment of this value is made on other architectures, including arm. However, arm64 adjusts this value by 4.

This breaks things like client idle polling, which relies on the tx ack status of a transmitted nullfunc frame. This patch adds code to report skb-attached tx status if requested by mac80211 or the rate control module. Since tx status is polled from a simple FIFO register, the code needs to account for the possibility of tx status events getting lost. The code keeps a list of skbs for which tx status is required and passes them to mac80211 once tx status has been filled in and the DMA queue is done with it. If a tx status event is not received after one second, the status rates are cleared, and a succesful ACK is indicated to avoid spurious disassoc during assoc or client polling.

Since the linked list entries themselves need to persist across subsequent kexec reboots, every reservation created this way results in two memblock_reserve() calls at the next boot. On arm64 systems with 100s of CPUs, this may result in a excessive number of memblock reservations, and needless fragmentation. So instead, make use of the newly updated struct linux_efi_memreserve layout to put multiple reservations into a single linked list entry. This should get rid of the numerous tiny memblock reservations, and effectively cut the total number of reservations in half on arm64 systems with many CPUs.

So, it's important to unmap these regions. Hence, introduce efi_unmap_pages() to unmap these regions from efi_pgd.

But, it's noticed that this is not so true in many x86 platforms. Hence, during boot, kernel reserves EFI boot services code/data regions [1] and maps [2] them to efi_pgd so that call to set_virtual_address_map() doesn't fail. After returning from set_virtual_address_map(), kernel frees the reserved regions [3] but they still remain mapped. Hence, introduce kernel_unmap_pages_in_pgd() which will later be used to unmap EFI boot services code/data regions. While at it modify kernel_map_pages_in_pgd() by: 1. Adding __init modifier because it's always used *only* during boot. 2.

Several functions in the efivars API assume __efivars is set, i.e., that they will be accessed only after efivars_register() has been called. However, the following NULL pointer access was reported calling efivar_entry_size() from the brcmfmac device driver: Unable to handle kernel NULL pointer dereference at virtual address 00000008 pgd = 60bfa5f1 [00000008] *pgd=00000000 Internal error: Oops: 5 [#1] SMP ARM ...

Heiko Carstens [1] said he would prefer s390 to use the common bust_spinlocks() as well: I did some code archaeology and this function is unchanged since ~17 years. When it was introduced it was close to identical to the x86 variant. All other architectures use the common code variant in the meantime. So if we change this I'd prefer that we switch s390 to the common code variant as well. Right now I can't see a reason for not doing that This patch removes s390 bust_spinlocks() and drops the weak attribute from the common bust_spinlocks() version.

This flag tells the firmware layer to do some pre- and maybe postprocessing. However, it may happen that this special flag is enabled but the firmware is unable to deal with this kind of message and thus returns with reply code 0x41. For example older firmware may not know the newest messages triggered by the zcrypt device driver and thus react with reject and the named reply code. Unfortunately this reply code is not known to the zcrypt error routines and thus default behavior is to switch the ap queue offline. This patch now makes the ap error routine aware of the reply code and so userspace is informed about the bad processing result but the queue is not switched to offline state any more.

One variable was for input only, the other for output. Looks like newer versions of the gcc don't like this. Anyway it is a better coding to use one variable (which may have a union data type) on one register for input and output. So this patch introduces unions and uses only one variable now for input and output for GR1 for the PQAP(QACT) and PQAP(QIC) invocation.

By using the trace_recursion mask, we can use a bit in the current task_struct to implement the notrace code, and move the logic out of fgraph.c and into trace_functions_graph.c and keeps it affecting only the tracer and not all call graph callbacks.

This muxed output is called "SYS 32K" in the module clock diagram, but otherwise referred to as the LOSC throughout the CCU documentation. The RC oscillator is not very accurate, even though it has an undocumented calibration function. We really want a precise clock at 32768 Hz, instead of something at around 32 KHz. This patch forces the SYS 32K clock to use the RTC output as its parent, and doesn't bother registering the internal oscillator nor a clock mux.

In this patch we allow forwarding port change event to mlx5 core interfaces (mlx5e/mlx5_ib) as it was received from FW. Once mlx5e and mlx5_ib start using this event we can safely remove the redundant software version of it and its translation logic.

ULP invokes ib_dma_map_sg() 2. ULP invokes ib_map_mr_sg() 3. ULP posts an IB_WR_REG_MR on the Send queue Step 2 generates an iova. It is permissible for ULPs to change this iova (with certain restrictions) between steps 2 and 3. rxe_map_mr_sg captures the MR's iova but later when rxe processes the REG_MR WR, it ignores the MR's iova field. If a ULP alters the MR's iova after step 2 but before step 3, rxe never captures that change. When the remote sends an RDMA Read targeting that MR, rxe looks up the R_key, but the altered iova does not match the iova stored in the MR, causing the RDMA Read request to fail.

If a great many filesystems are mounted, this can cause a noticable slow-down in, for example, system shutdown. The sequence: mkdir -p /tmp/Mtest/{0..5000} time for i in /tmp/Mtest/*; do mount -t tmpfs tmpfs $i ; done time umount /tmp/Mtest/* on a 4-cpu VM can report 8 seconds to mount the tmpfs filesystems, and 100 seconds to unmount them. Boot the same VM with 1 CPU and it takes 18 seconds to mount the tmpfs filesystems, but only 36 to unmount. If we change the synchronize_rcu() to synchronize_rcu_expedited() the umount time on a 4-cpu VM drop to 0.6 seconds I think this 200-fold speed up is worth the slightly high system impact of using synchronize_rcu_expedited().

Things work by chance currently as under normal circumstances its the first CPU of each cluster which is used by the operating systems to probe the cooling devices. But as soon as this CPU ordering changes and any other CPU is used to bring up the cooling device, we will start seeing failures. Also the DT is rather incomplete when we list only one CPU in the cooling maps, as the hardware doesn't have any such limitations. Update cooling maps to include all devices affected by individual trip points.

This means that even when we change the function of the pad from GPIO to anything else, the bias previously set still applies. As we have seen with the eMMC, depending on the bias type and the function, it may trigger problems. The underlying issue is that we inherit whatever was left by previous user of the pad (pinconf, u-boot or the ROM code). As a consequence, the actual setup we will get is undefined. There is nothing mentioned in the documentation about pad bias and pinmux function, however leaving it undefined is not an option. This change consistently disable the pad bias for every pinmux functions. It seems to work well, we can only assume that the necessary bias (if any) is already provided by the pin function itself.

This allows a list of requests to be issued, with nvme only writing the SQ update when it's necessary. This is more efficient if we have lists of requests to issue, particularly on virtualized hardware, where writing the SQ doorbell is more expensive than on real hardware. For those cases, performance increases of 2-3x have been observed. The use case for this is plugged IO, where blk-mq flushes a batch of requests at the time.

The point is that hardware can defer costly doorbell type writes to the last request. But if we run into errors issuing a sequence of requests, we may never send the request with bd->last == true set. For that case, we need a hook that tells the hardware that nothing else is coming right now. For failures returned by the drivers ->queue_rq() hook, the driver is responsible for flushing pending requests, if it uses bd->last to optimize that part. This works like before, no changes there.

It's complicated by the state clear that occurs on deadlock. ATM, there's no way to inject code in the deadlock path with the helpers, so it's unfit for conversion.

This patch makes full use of the generic fbdev emulation by using its drm_client callbacks. This means that drm_mode_config_funcs->output_poll_changed and drm_driver->lastclose are now handled by the emulation code. Additionally fbdev unregister happens automatically on drm_dev_unregister(). The drm_fbdev_generic_setup() call is put after drm_dev_register() in the driver. This is done to highlight the fact that fbdev emulation is an internal client that makes use of the driver, it is not part of the driver as such. If fbdev setup fails, an error is printed, but the driver succeeds probing. drm_fbdev_generic_setup() handles mode_config.num_connector being zero. In that case it retries fbdev setup on the next .output_poll_changed.

There is a second bug because the error handling calls blk_mq_free_tag_set(&unit[i].tag_set); regardless of whether "disk->queue" is NULL or non-NULL. So if blk_mq_init_sq_queue() fails, then that means unit[i].tag_set->tags is NULL and it leads to an Oops. It's easiest to call put_disk() before the goto to clean up the partial iteration. Then the earlier unit[] elements are fully allocated so we can remove the checks whether "disk->queue" is NULL and the code is simpler.

These properties mean that respective signal is active HIGH since the SDHCI specification stipulates that this kind of signals should be treated as active LOW. If the twocell GPIO flag is also specified as active low, well that's nice and we will silently ignore the tautological specification. If however the GPIO line is specified as active low in the GPIO flasg cell and "cd-inverted" or "wp-inverted" is also specified, the latter takes precedence and we print a warning. The current effect on the MMC slot-gpio core are as follows: For CD GPIOs: no effect. The current code in mmc/core/host.c calls mmc_gpiod_request_cd() with the "override_active_level" argument set to true, which means that whatever the GPIO descriptor thinks about active low/high will be ignored, the core will use the MMC_CAP2_CD_ACTIVE_HIGH to keep track of this and reads the raw value from the GPIO descriptor, totally bypassing gpiolibs inversion semantics. I plan to clean this up at a later point passing the handling of inversion semantics over to gpiolib, so this patch prepares the ground for that. Fow WP GPIOs: this is probably fixing a bug, because the code in mmc/core/host.c calls mmc_gpiod_request_ro() with the "override_active_level" argument set to false, which means it will respect the inversion semantics of the gpiolib and ignore the MMC_CAP2_RO_ACTIVE_HIGH flag for everyone using this through device tree. However the code in host.c confusingly goes to great lengths setting up the MMC_CAP2_RO_ACTIVE_HIGH flag from the GPIO descriptor and by reading the "wp-inverted" property of the node. As far as I can tell this is all in vain and the inversion is broken: device trees that use "wp-inverted" do not work as intended, instead the only way to actually get inversion on a line is by setting the second cell flag to GPIO_ACTIVE_HIGH (which will be the default) or GPIO_ACTIVE_LOW if they want the proper MMC semantics. Presumably all device trees do this right but we need to parse and handle this properly.

Take get_ksymbol() for instance - are we looking for an exported symbol or a kallsyms symbol here? Or symname() and kernel_symbol_name() - which function handles an exported symbol and which one an Elf symbol?

It uses ymm registers only to avoid the massive core throttling on Skylake-X platforms. Nontheless does it bring a ~30% speed improvement compared to the AVX2 variant for random encryption lengths. The AVX2 version uses "rep movsb" for partial block XORing via the stack. With AVX-512, the new "vmovdqu8" can do this much more efficiently. The associated "kmov" instructions to work with dynamic masks is not part of the AVX-512VL instruction set, hence we depend on AVX-512BW as well. Given that the major AVX-512VL architectures provide AVX-512BW and this extension does not affect core clocking, this seems to be no problem at least for now.

This could happen if ->cbm_validate() is NULL which could leave cbm_val uninitialized. However, there is no case where ->cbm_validate() can be NULL as it is initialized based on a vendor check. So it is either an Intel or an AMD version it points to. And in both the cases it is initialized properly. Thus, remove the first check. Verified the fix running Smatch.

This doesn't even remotely describe the actual Versatile Express hardware. Exploit the SiI9022 bridge by connecting the PL111 pads to it, making it use EDID or fallback values to drive the monitor. The also has to use the reserved memory through the CMA pool rather than by open coding a memory region and remapping it explicitly in the driver. To achieve this, a reserved-memory node must exist in the root of the device tree, so we need to pull that out of the motherboard .dtsi include files, and push it into each top-level device tree instead. We do the same manouver for all the Versatile Express boards, taking into account the different location of the video RAM depending on which chip select is used on each platform. This plays nicely with the new PL111 DRM driver and follows the standard ways of assigning bridges and memory pools for graphics.

The first patch is by Colin Ian King and fixes the spelling in the ucan driver. The next three patches target the xilinx driver. YueHaibing's patch fixes the return type of ndo_start_xmit function. Two patches by Shubhrajyoti Datta add support for the CAN FD 2.0 controllers. Flavio Suligoi's patch for the sja1000 driver add support for the ASEM CAN raw hardware. Wolfram Sang's and Kuninori Morimoto's patches switch the rcar driver to use SPDX license identifiers. The remaining 111 patches improve the flexcan driver. Pankaj Bansal's patch enables the driver in Kconfig on all architectures with IOMEM support. The next four patches by me fix indention, add missing parentheses and comments. Aisheng Dong's patches add self wake support and document it in the DT bindings. The remaining patches by Pankaj Bansal first fix the loopback support and prepare the driver for the CAN-FD support needed for the LX2160A SoC. The actual CAN-FD support will be added in a later patch series. ==================== Signed-off-by: David S.

Same driver is used across tegra platforms and it is necessary to distinguish between platforms to use platform specific settings from userspace. One such example is, hdmi port on different platforms use different alsa pcm device ID. For hdmi playback to work it should open correct pcm device depending on the platform. This patch applies shortname from first compatible string provided in root node of device tree. Userspace then can use this card name to apply specific settings.

This means that even when we change the function of the pad from GPIO to anything else, the bias previously set still applies. As we have seen with the eMMC, depending on the bias type and the function, it may trigger problems. The underlying issue is that we inherit whatever was left by previous user of the pad (pinconf, u-boot or the ROM code). As a consequence, the actual setup we will get is undefined. There is nothing mentioned in the documentation about pad bias and pinmux function, however leaving it undefined is not an option. This change consistently disable the pad bias for every pinmux functions. It seems to work well, we can only assume that the necessary bias (if any) is already provided by the pin function itself.

For the mic-mute LED trigger, a common fixup function, snd_hda_gen_fixup_micmute_led(), is provided to be called for the corresponding quirk entries. This sets up the capture sync hook with ledtrig_audio_set() call appropriately. For the mute LED trigger, which is done currently only for thinkpad_acpi, the call is replaced with ledtrig_audio_set() as well. Overall, the beauty of the new implementation is that the whole ugly bindings with request_symbol() are dropped, and also that it provides more flexibility to users. One potential behavior change by this patch is that the mute LED enum may be created on machines that actually have no LED device. In the former code, we did test-call and abort binding if the test failed. But with the LED-trigger binding, this test isn't possible, and the actual check is done in the LED class device side. So it's the downside of simpleness. Also, note that the HD-audio codec driver doesn't select CONFIG_LEDS and co by itself. It's supposed to be selected by the platform drivers instead.

This patch is the last piece of preparation: adding the audio mute / mic-mute LED class devices to thinkpad_acpi driver. Two devices, platform::mute and platform::micmute, will be added for controlling the mute LED and mic-mute LED, respectively. The new prefix "platform" is the suggestion by upstream for indicating the generic laptop attribute. Also this selects CONFIG_LEDS_TRIGGERS and CONFIG_LEDS_TRIGGERS_AUDIO unconditionally. Strictly speaking, these aren't 100% mandatory, but leaving these manual selections would lead to a functional regression easily once after converting from the dynamic symbol binding to the LEDs trigger in a later patch.

As of this patch, the LED device isn't tied with the audio driver, and can be changed via user-space at "platform::micmute" sysfs entry. (This new prefix "platform" is the agreement among people for indicating the generic laptop / system-wide attribute.) The binding with HD-audio is still done via the existing exported dell_micmute_led_set(). It will be replaced with the LED trigger binding in later patches. Also this selects CONFIG_LEDS_TRIGGERS and CONFIG_LEDS_TRIGGERS_AUDIO unconditionally. Strictly speaking, these aren't 100% mandatory, but leaving these manual selections would lead to a functional regression easily once after converting from the dynamic symbol binding to the LEDs trigger in a later patch.

The notify_freesync and set_freesync_property functions are dropped from amdgpu_display_funcs. The drm vrr_capable property is now attached to any DP/HDMI connector. Its value is updated accordingly to the connector's FreeSync capabiltiy. The freesync_enable logic and ioctl control has has been dropped in favor of utilizing the vrr_enabled on the drm CRTC. This allows for more fine grained atomic control over which CRTCs should support variable refresh rate. To handle state changes for vrr_enabled it was easiest to drop the forced modeset on freesync_enabled change. This patch now performs the required stream updates when planes are flipped. This is done for a few reasons: (1) VRR stream updates can be done in the fast update path (2) amdgpu_dm_atomic_check would need to be hacked apart to check desired variable refresh state and capability before the CRTC disable pass. (3) Performing VRR stream updates on-flip is needed for enabling BTR support. VRR packets and timing adjustments are now tracked and compared to previous values sent to the hardware.

This results in a vpos being returned from amdgpu_display_get_crtc_scanoutpos that's a positive value. The positive value indicates to the caller that the display is currently in scanout when the display is actually still in vblank. This is because the vfront porch duration is unknown with variable refresh active and will end when either a page flip occurs or the timeout specified by the driver/display is reached. The behavior of the amdgpu_display_get_crtc_scanoutpos remains the same when the position is below vtotal. When the position is above vtotal the function will return a value that is effectively -vbl_end, the size of the vback porch. The only caller affected by this change is the DRM helper for calculating vblank timestamps. This change corrects behavior for calculating the page flip timestamp from being the previous timestamp to the calculation to the next timestamp when position >= vtotal.

Capability for variable refresh rate support should be determined by querying the vrr_capable drm connector property.

If the first commit modifies streams or planes those will be missing from the dc->current_state for the second atomic check. This result in many stream and plane errors in atomic commit tail. [How] The driver still needs to track old to new state to determine if the commit in its current implementation. Updating the dc_state in atomic tail is wrong since the dc_state swap should be happening as part of drm_atomic_helper_swap_state *before* the worker queue kicks its work off. The simplest replacement for the subclassing (which doesn't properly manage the old to new atomic state swap) is to use the drm private object helpers. While some of the dc_state members could be merged into dm_crtc_state or dm_plane_state and copied over that way it is easier for now to just treat the whole dc_state structure as a single private object. This allows amdgpu_dm to drop the dc->current_state copy from within atomic check. It's replaced by a copy from the current atomic state which is propagated correctly for the sequence described above. Since access to the dm_state private object is now locked this should also fix issues that could arise if submitting non-blocking commits from different threads.

With NV12 the plane state would be coming from the master (UV) plane whereas the plane we're programming is the slave (Y) plane. For that reason we need to explicitly pass around the slave plane (or we'd have to otherwise deduce it by checking whether we were called via .update_plane() or .update_slave()). In the case of icl_program_input_csc_coeff() it's actually OK to assume that we are always the master plane because the input CSC only exists on HDR planes which can never be a slave plane. But for consistency let's pass in the plane explicitly anyway. While at it drop the "_coeff" from the function name since it's kinda redundant, and this makes the name a bit shorter :) Cc: Uma Shankar Cc: Maarten Lankhorst Signed-off-by: Ville Syrjälä Link: https://patchwork.freedesktop.org/patch/msgid/20181114210729.16185-14-ville.syrjala@linux.intel.com Reviewed-by: Uma Shankar Reviewed-by: Maarten Lankhorst Reviewed-by: Matt Roper commit 45bee430b8438a26e0da7c664605ceea97823ec8 Author: Ville Syrjälä Date: Wed Nov 14 23:07:28 2018 +0200 drm/i915: Rename the confusing 'plane_id' to 'color_plane' A variable whose name is 'plane_id' is expected to be of the enum plane_id type.

Not 100% sure but we can try to keep them near to the surface register as well - chv pipe b csc register are double buffered but self arming so moving them down a bit - the rest should be mostly armed by the surface register so we can safely write them first, and to just for some consistency let's try to follow keep them in order based on the register offset None of this will have any effect of course unless the vblank evasion fails (which it still does sometimes).

Miller commit 7e273a8ebdd3b83f94eb8b49fc8ee61464f47cc2 Author: Ioana Ciocoi Radulescu Date: Mon Nov 26 16:27:29 2018 +0000 dpaa2-eth: Add basic XDP support We keep one XDP program reference per channel. The only actions supported for now are XDP_DROP and XDP_PASS. Until now we didn't enforce a maximum size for Rx frames based on MTU value. Change that, since for XDP mode we must ensure no scatter-gather frames can be received. Signed-off-by: Ioana Radulescu Acked-by: Camelia Groza Reviewed-by: David Ahern Signed-off-by: David S.

This rule is not fulfilled if a transfer consists of multiple sglist entries, one per page, and the first entry starts in the middle of a page with an offset not a multiple of 4. The driver currently falls back to programmed I/O for such transfers, incurring a significant performance penalty. Overcome this hardware limitation by transferring the first few bytes of a transfer without DMA such that the remainder of the first sglist entry becomes a multiple of 4. Specifics are provided in kerneldoc comments. An alternative approach would have been to split transfers in the ->prepare_message hook, but this may necessitate two transfers per page, defeating the goal of clustering multiple pages together in a single transfer for efficiency. E.g. if the first TX sglist entry's length is 23 and the first RX's is 40, the first transfer would send and receive 23 bytes, the second 40 - 23 = 17 bytes, the third 4096 - 17 = 4079 bytes, the fourth 4096 - 4079 = 17 bytes and so on. In other words, O(n) transfers are necessary (n = number of sglist entries), whereas the algorithm implemented herein only requires O(1) additional work.

However, in upcoming SOC LX2160A the message buffers can have payload size 64 bytes. This results in less than 32 MBs per partition and some empty area is left at the end of each partition.This empty area should not be accessed.

Afterwards it decides whether the transfer is finished by checking if the TX FIFO is empty. If very few bytes were written to the TX FIFO, they may already have been transmitted by the time the FIFO's emptiness is checked. As a result, the transfer will be declared finished and the chip will be reset without reading the corresponding received bytes from the RX FIFO. The odds of this happening increase with a high clock frequency (such that the TX FIFO drains quickly) and either passing "threadirqs" on the command line or enabling CONFIG_PREEMPT_RT_BASE (such that the IRQ handler may be preempted between filling the TX FIFO and checking its emptiness). Fix by instead checking whether rx_len has reached zero, which means that the transfer has been received in full. This is also more efficient as it avoids one bus read access per interrupt. Note that bcm2835_spi_transfer_one_poll() likewise uses rx_len to determine whether the transfer has finished.

Thus an early reset driver was created. This early reset driver is only for the SoCFPGA 32-bit platform. The Stratix10 platform does not need any of the timers that in reset to boot, thus we don't need to early reset driver.

For DMICs, this can result in the clock being turned off very quickly, which may not compatible with internal state machine transition requirements. This patch add a mode-switch delay which will prevent the clock from being turned off without complying with manufacturer timing specifications. While the DMIC clock may be controlled at a lower level, be it with hardware or firmware, applying the delay during the STOP_TRIGGER phase ensures that there is no race condition, e.g. with the hardware/firmware turning off the clock earlier Signed-off-by: Sathyanarayana Nujella Signed-off-by: Jairaj Arava Signed-off-by: Harsha Priya Signed-off-by: Jenny TC Signed-off-by: Mark Brown commit 22cc062c4dfb16330fe18e8d7e155d733fd59e61 Author: Peter Ujfalusi Date: Wed Nov 14 14:46:30 2018 +0200 dt-bindings: sound: omap-mcpdm: Update documentation for pdmclk McPDM module receives it's functional clock from external source.

Even though it's not directly used, muxes will end up traversing the entire clk tree on calls to determine_rate if it doesn't exist. This is because the 32k clk is listed as a possible parent on some clks. Since the clk doesn't know about the 32k clk (it was never registered), it triggers a global search for it. This can happen about 40 times per second, which isn't great for power.

OTOH, commit e894efef9ac7 ("ASoC: core: add support to card rebind") allows to rebind sound card without rebinding all drivers. Because of above patch and dvc.c flags, it can't re-register kctrl if only sound card was rebinded, because dvc is keeping old flags. (Of course it will be no problem if rsnd driver also be rebinded, but it is not purpose of above patch). This patch checks current card registered kctrl when registering. In MIXer case, it can avoid duplicate register if card already has same kctrl. In rebind case, it can re-register kctrl because card registered kctl had been removed when unbinding.

In the case of internal reload (e.g., mtu change), there could be a race between link-up notification from mfw and the driver unload processing. In such case kernel assumes the link is up and starts using the queues which leads to the server crash. Send link notification to the kernel only when driver has already requested MFW for the link.

The values represented by qede->flags is being used in mixed ways: 1. As 'value' at some places e.g., QEDE_FLAGS_IS_VF usage 2. As bit-mask(value) at some places e.g., QEDE_FLAGS_PTP_TX_IN_PRORGESS usage. This implementation pose problems in future when we want to add more flag values e.g., overlap of the values, overflow of 64-bit storage. Updated the implementation to go with approach (2) for qede->flags. Signed-off-by: Sudarsana Reddy Kalluru Signed-off-by: Ariel Elior Signed-off-by: Michal Kalderon Signed-off-by: David S.

The driver has similar structure with other ASIX MAC drivers (AX88179), but with a number of important differences: - Driver supports both direct Phy and custom firmware interface for Phy programming. This is due to different firmware modules available with this product. - Driver handles new 2.5G/5G link speed configuration and reporting. - Device support all speeds from 100M up to 5G. - Device supports MTU up to 16K. Device supports various standard networking features, like checksum offloads, vlan tagging/filtering, TSO. The code of this driver is based on original ASIX sources and was extended by Aquantia for 5G multigig support. Patchset v2 includes following changes: - Function variables declarions fixed to reverse xmass tree - Improve patch layout structure - Remove unnecessary curly braces in switch/case statements - Use 'packed' attribute for HW structures only - Use eth_mac_addr function in set_mac_addr callback - Remove unnecessary 'memset' calls. - Read MAC address from EEPROM function has now better name - Use driver_priv field to store context. It avoids ugly cast. - Set max_mtu field. Remove check for MTU size - Rewrite read/write functions. Add helpers for read/write 16/32 bit values - Use mask and shifts instead of bitfields to support BE platforms. - Use stack allocated buffer for configuring mcast filters - Use AUTONEG_ENABLE when go to suspend state - Pad out wol_cfg field from context structure. Use stack allocated instead - Remove driver version - Check field 'duplex' in set_link_ksetting callback as well - Use already created defines in usb matching macro - Rename phy_ops struct to phy_cfg - Use ether_addr_copy for copying mac address - Add fall-through comment in switch/case for avoid checkpatch warning - Remove match for CDC ether device - Add ASIX's HW id-s to match this driver - Add all HW id-s with which driver can work to blacklist of cdc_ether driver Patchset v3 includes following changes: - Use linkmode_copy instead of bitmap_copy - Remove Direct PHY access code since production HW will not have this mode anymore - Fix line over 80 symbols and alignments in cdc_ether patch - Add match for ECM configuration On start our HW reports both ECM and vendor configs. Linux prefers to use ECM driver and chooses active configuration which is for ecm driver (not for vendor specific). We need to match this configuration and forcibly switch configuration to vendor specific. Patchset v4 includes following changes: - Set gso_max_size. - Optimize accessing to descriptors - Use SKB_TRUESIZE macro. ==================== Signed-off-by: David S.

However, the device cannot assign a VNI to such FIDs, which prevents the driver from supporting the enslavement of VxLAN devices to the VLAN-aware bridge. This patchset works around this limitation by emulating 802.1Q FIDs using 802.1D FIDs, which can be assigned a VNI and so far have only been used in conjunction with VLAN-unaware bridges. The downside of this approach is that multiple {Port,VID}->FID entries are required, whereas a single VID->FID entry is required with "true" 802.1Q FIDs. First four patches introduce the new FID family of emulated 802.1Q FIDs and the associated type of router interfaces (RIFs). Last patch flips the driver to use this new FID family. The diff is relatively small because the internal implementation of each FID family is contained and hidden in spectrum_fid.c. Different internal users (e.g., bridge, router) are aware of the different FID types, but do not care about their internal implementation. This makes it trivial to swap the current implementation of 802.1Q FIDs with the new one, using 802.1D FIDs. ==================== Signed-off-by: David S.

If the new no_linklocal_learn option is enabled then the bridge will stop learning from link-local packets. In order to save space for future boolean options, patch 01 adds a new bool option API that uses a bitmask to control boolean options. The bridge is by far the largest netlink attr user and we keep adding simple boolean options which waste nl attr ids and space. We're not directly mapping these to the in-kernel bridge flags because some might require more complex configuration changes (e.g. if we were to add the per port vlan stats now, it'd require multiple checks before changing value). Any new bool option needs to be handled by both br_boolopt_toggle and get in order to be able to retrieve its state later. All such options are automatically exported via netlink. The behaviour of setting such options is consistent with netlink option handling when a missing option is being set (silently ignored), e.g. when a newer iproute2 is used on older kernel. All supported options are exported via bm's optmask when dumping the new attribute. v2: address Andrew Lunn's comments, squash a minor change into patch 01, export all supported options via optmask when dumping, add patch 03, pass down extack so options can return meaningful errors, add WARN_ON on unsupported options (should not happen) ==================== Signed-off-by: David S.

Miller commit a428afe82f98d2ffb31c981671630df1fa25906f Author: Nikolay Aleksandrov Date: Sat Nov 24 04:34:20 2018 +0200 net: bridge: add support for user-controlled bool options We have been adding many new bridge options, a big number of which are boolean but still take up netlink attribute ids and waste space in the skb. Recently we discussed learning from link-local packets[1] and decided yet another new boolean option will be needed, thus introducing this API to save some bridge nl space. The API supports changing the value of multiple boolean options at once via the br_boolopt_multi struct which has an optmask (which options to set, bit per opt) and optval (options' new values). Future boolean options will only be added to the br_boolopt_id enum and then will have to be handled in br_boolopt_toggle/get. The API will automatically add the ability to change and export them via netlink, sysfs can use the single boolopt function versions to do the same. The behaviour with failing/succeeding is the same as with normal netlink option changing. If an option requires mapping to internal kernel flag or needs special configuration to be enabled then it should be handled in br_boolopt_toggle. It should also be able to retrieve an option's current state via br_boolopt_get. v2: WARN_ON() on unsupported option as that shouldn't be possible and also will help catch people who add new options without handling them for both set and get. Pass down extack so if an option desires it could set it on error and be more user-friendly.

A few occurrences exist where rdt_last_cmd_printf() is used to print a simple string. Doing so does not result in incorrect result or incorrect behavior, but rdt_last_cmd_puts() is the function intended to be used in these cases, as it is faster and it doesn't need to do the vsnprintf() formatting. Fix these occurrences to use rdt_last_cmd_puts() instead. While doing so, fix two typos that were recently introduced into two of these simple strings.

Whilst this does the job of avoiding lock-ups, we can actually be a bit smarter by defining this as PTRS_PER_PTE. Due to the structure of our page tables, using PTRS_PER_PTE means that an outer loop calling flush_tlb_range() for entire table entries will end up performing just a single TLBI operation for each entry. As an example, mremap()ing a 1GB range mapped using 4k pages now requires only 512 TLBI operations when moving the page tables as opposed to 262144 operations (512*512) when using the current threshold of 1024.

This is problematic because this function accesses and updates the srcu_data structure's ->srcu_cblist, which is protected by that lock. Failing to hold this lock can result in corruption of the SRCU callback lists, which in turn can result in arbitrarily bad results. This commit therefore makes srcu_gp_start() acquire the srcu_data structure's ->lock across the calls to rcu_segcblist_advance() and rcu_segcblist_accelerate(), thus preventing this corruption.

Unfortunately, on arm64 where the underlying delay loop is implemented as a read of the architected counter, the CPU does not guarantee ordering from the readl() to the delay loop and therefore the delay loop could in theory be speculated and not provide the desired interval between the two writes. Fix this in a similar manner to PowerPC by introducing a dummy control dependency on the output of readX() which, combined with the ISB in the read of the architected counter, guarantees that a subsequent delay loop can not be executed until the readX() has returned its result.

This can lead to issues as all of gpio-, regulator- and pwm-state are used to determine the initial state and the bootloader or kernel can leave them in an inconsistent state at boot. In my case on rk3399-kevin, the pwm backlight is build as module and the kernel disables the supply regulator as unused while keeping the pwm running thus pwm_bl calling pwm_backlight_power_off() during probe and creating an unmatched regulator-disable call, as it never got enabled from the pwm-bl before.

Originally, both notifications were done from scheduled work context and all that kernfs_notify() did was schedule the work. This patch simply moves the poll notification from the scheduled work handler to kernfs_notify(). The fsnotify notification still needs to be done from scheduled work context because it can sleep (it needs to lock a mutex). If the poll notification is time critical (the notified thread needs to wake as quickly as possible), it's better to do it from kernfs_notify() directly. One example is calling sysfs_notify_dirent() from a hardware interrupt handler to wake up a thread and handle the interrupt in user space.

The function will be called as many times as necessary until all the elements are copied". Now, this approach already forces the function to loop around elements and felt convoluted, so it was changed to a more straightforward "Copy all the elements into memory as long as they fit". The resulting function is shorter and simpler.

In practice, this means that the alpha component cannot be preserved when going through the frontend. Since the information is lost, ARGB is not properly supported. As a result, expose the matching format supported by the frontend (both for input and output) as XRGB instead of ARGB. Since ARGB was the selected format for connecting the frontend to the backend, change it to XRGB to reflect this as well. The A31 and A80 SoCs apparently have a bit to enable proper alpha, but this is not supported at this point (see the comment already in the code).

But in get_more_blocks(), @create has been overwritten by below code. So the function f2fs_map_blocks() will not allocate new block address but directly go out. Meanwile,there are several functions calling f2fs_map_blocks() directly and @map.m_may_create not initialized. CODE: create = dio->op == REQ_OP_WRITE; if (dio->flags & DIO_SKIP_HOLES) { if (fs_startblk <= ((i_size_read(dio->inode) - 1) >> i_blkbits)) create = 0; } This patch fixes it.

Add simple verification that all global symbols exported with LIBBPF_API are versioned in libbpf.map version script. The idea is to check that number of global symbols in libbpf-in.o, that is the input to the linker, matches with number of unique versioned symbols in libbpf.so, that is the output of the linker. If these numbers don't match, it may mean some symbol was not versioned and make will fail. "Unique" means that if a symbol is present in more than one version of ABI due to ABI changes, it'll be counted once. Another option to calculate number of global symbols in the "input" could be to count number of LIBBPF_ABI entries in C headers but it seems to be fragile. Example of output when a symbol is missing in version script: ... LD libbpf-in.o LINK libbpf.a LINK libbpf.so Warning: Num of global symbols in libbpf-in.o (115) does NOT match with num of versioned symbols in libbpf.so (114).

Usual way to do ABI versioning is version script for the linker. Add such a script for libbpf. All global symbols currently exported via LIBBPF_API macro are added to the version script libbpf.map. The version name LIBBPF_0.0.1 is constructed from the name of the library + version specified by $(LIBBPF_VERSION) in Makefile. Version script does not duplicate the work done by LIBBPF_API macro, it rather complements it. The macro is used at compile time and can be used by compiler to do optimization that can't be done at link time, it is purely about global symbol visibility. The version script, in turn, is used at link time and takes care of ABI versioning. Both techniques are described in details in [1]. Whenever ABI is changed in the future, version script should be changed appropriately.

So, to reduce impact of GC on large size section, this patch supports subsectional GC, in one cycle of GC, it only migrate partial segment{s} in victim section. Currently, by default, we use sbi->segs_per_sec as migration granularity.

These mounts are done automatically by the kernel either as part of mounting some parent mount (e.g. debugfs always mounts tracefs under "tracing" for compatibility) or they are mounted automatically as needed on subdirectory accesses (e.g. NFS crossmnt mounts). Since such automounts are either an implicit consequence of the parent mount (which is already checked) or they can happen during regular accesses (where it doesn't make sense to check against the current task's context), the mount permission check should be skipped for them. Without this patch, attempts to access contents of an automounted directory can cause unexpected SELinux denials. In the current kernel tree, the MS_SUBMOUNT flag is set only via vfs_submount(), which is called only from the following places: - AFS, when automounting special "symlinks" referencing other cells - CIFS, when automounting "referrals" - NFS, when automounting subtrees - debugfs, when automounting tracefs In all cases the submounts are meant to be transparent to the user and it makes sense that if mounting the master is allowed, then so should be the automounts. Note that CAP_SYS_ADMIN capability checking is already skipped for (SB_KERNMOUNT|SB_SUBMOUNT) in: - sget_userns() in fs/super.c: if (!(flags & (SB_KERNMOUNT|SB_SUBMOUNT)) && !(type->fs_flags & FS_USERNS_MOUNT) && !capable(CAP_SYS_ADMIN)) return ERR_PTR(-EPERM); - sget() in fs/super.c: /* Ensure the requestor has permissions over the target filesystem */ if (!(flags & (SB_KERNMOUNT|SB_SUBMOUNT)) && !ns_capable(user_ns, CAP_SYS_ADMIN)) return ERR_PTR(-EPERM); Verified internally on patched RHEL 7.6 with a reproducer using NFS+httpd and selinux-tesuite.

Simply provide register/unregister notifiers API and call the notifier chain on firmware async events. Example: to subscribe to a FW event: struct mlx5_nb port_event; MLX5_NB_INIT(&port_event, port_event_handler, PORT_CHANGE); mlx5_eq_notifier_register(mdev, &port_event); where: - port_event_handler is the notifier block callback. - PORT_EVENT is the suffix of MLX5_EVENT_TYPE_PORT_CHANGE. The above will guarantee that port_event_handler will receive all FW events of the type MLX5_EVENT_TYPE_PORT_CHANGE. To receive all FW/HW events one can subscribe to MLX5_EVENT_TYPE_NOTIFY_ANY. The next few patches will start moving all mlx5 core components to use this new API and cleanup mlx5_eq_async_int misx handler from component explicit calls and specific logic.

ABM will adjust in response to the pixel luminance of the displayed content. ABM is made available as a drm property on eDP monitors called "abm level", which ranges from 0 to 4. When this property is set to 0, ABM is off. Levels 1 to 4 represent different ranges of backlight reduction. At higher levels both the backlight reduction and pixel adjustment will be greater. ABM requires DMCU firmware, which is currently available for Raven ASICs only. If the feature does not work, please ensure your firmware is up to date. v2: Fix commit message, only attach property if DMCU loaded v3: Store ABM level in crtc state to accommodate dc v4: Fix ABM saving on dpms cycle Signed-off-by: David Francis Reviewed-by: Harry Wentland Signed-off-by: Alex Deucher commit bbf854dc3570eb0a2b9d851f21e363e1570c717e Author: David Francis Date: Mon Nov 26 11:38:33 2018 -0500 drm/amd/display: Load DMCU IRAM DMCU IRAM must be loaded by the driver before DMCU can function.

Wysocki commit 59abd83672f70cac4b6bf9b237506c5bc6837606 Author: Heikki Krogerus Date: Fri Nov 9 17:21:36 2018 +0300 drivers: base: Introducing software nodes to the firmware node framework Software node is a new struct fwnode_handle type that can be used to describe devices in kernel (software). It is meant to complement fwnodes representing real firmware nodes when they are incomplete (for example missing device properties) and to supply the primary fwnode when the firmware lacks hardware description for a device completely. The software node type is really meant to replace the currently used "property_set" struct fwnode_handle type. The handling of struct property_set is glued to the generic device property handling code, and it is not possible to create a struct property_set independently from the device that it is bind to. struct property_set is only created when device properties are added to already initialized struct device, and control of it is only possible from the generic property handling code. Software nodes are instead designed to be created independently from the device entries (struct device). It makes them much more flexible, as then the device meant to be bind to the node can be created at a later time, and from another location. It is also possible to bind multiple devices to a single software node if needed. The software node implementation also includes support for node hierarchy, which was the main motivation for this commit. The node hierarchy was something that was requested for the struct property_set, but it did not seem reasonable to try to extend the property_set support for that purpose. struct property_set was really meant only for device property handling like the name suggests. Support for struct property_set is not yet removed in this commit, but it will be in the following one.

For now a single "platform_notify" callback function was used to notify the underlying base system which is in charge of the hardware description when a new device entry was added to the system, but that callback is available to only a single base system at the time. This will add a function device_platform_notify() and replace all direct platform_notify() calls with it. device_platform_notify() will first simply call the platform_notify() callback, so this commit has no functional affect, however, the idea is that individual base systems will put their direct notification calls there instead of using the platform_notify function pointer.

After that commit we only updated the total load when enabling / disabling a regulator where a consumer specified a load or when changing the consumer load on an enabled regulator. The problem with the new scheme is that if there is a system load specified for a regulator but no consumers specify a load then we never account for it. Let's account for the system load in set_machine_constraints(). NOTE: with the new scheme we end up with a bit of a quandry. What if someone specifies _both_ an initial mode and a system load? If we take the system load into account right at init time then it will effectively clobber the initial mode. We'll resolve this by saying that if both are specified then the initial mode will win. The system load will then only take effect if/when a consumer specifies a load. If no consumers ever specify a load then the initial mode will persist and the system load will have no effect.

Whilst this opens up a race with page reclaim, where a PTE in active use via a stale, young TLB entry does not update the underlying descriptor, the worst thing that happens is that the page is reclaimed and then immediately faulted back in. Given that we have a DSB in our context-switch path, the window for a spurious reclaim is fairly limited and eliding the barrier claims to boost NVMe/SSD accesses by over 10% on some platforms. A similar optimisation was made for x86 in commit b13b1d2d8692 ("x86/mm: In the PTE swapout page reclaim case clear the accessed bit instead of flushing the TLB").

It makes the assumption that the bootloader properly initialized the regulator, and just in case enables the regulator anyway. Some constraints however currently get missed, such as the soft-start and ramp-delay. This causes the regulator to be enabled, without the soft-start and ramp-delay being applied, which in turn can cause high-currents or other start-up problems. By moving the always-enabled constraints later in the constraints check, we can at least ensure all constraints for the regulator are followed.

Things work by chance currently as under normal circumstances its the first CPU of each cluster which is used by the operating systems to probe the cooling devices. But as soon as this CPU ordering changes and any other CPU is used to bring up the cooling device, we will start seeing failures. Also the DT is rather incomplete when we list only one CPU in the cooling maps, as the hardware doesn't have any such limitations. Update cooling maps to include all devices affected by individual trip points.

The driver uses this number to schedule the isochronous transfer and passes it to the START TRANSFER command. Because this number is invalid, the command may fail. If BIT[15:14] matches the internal 16-bit microframe, the START TRANSFER command will pass and the transfer will start at the scheduled time, if it is off by 1, the command will still pass, but the transfer will start 2 seconds in the future. For all other conditions, the START TRANSFER command will fail with bus-expiry. In order to workaround this issue, we can test for the correct combination of BIT[15:14] by sending START TRANSFER commands with different values of BIT[15:14]: 'b00, 'b01, 'b10, and 'b11. Each combination is 2^14 uframe apart (or 2 seconds). 4 seconds into the future will result in a bus-expiry status. As the result, within the 4 possible combinations for BIT[15:14], there will be 2 successful and 2 failure START COMMAND status. One of the 2 successful command status will result in a 2-second delay start. The smaller BIT[15:14] value is the correct combination. Since there are only 4 outcomes and the results are ordered, we can simply test 2 START TRANSFER commands with BIT[15:14] combinations 'b00 and 'b01 to deduce the smaller successful combination. Let test0 = test status for combination 'b00 and test1 = test status for 'b01 of BIT[15:14]. The correct combination is as follow: if test0 fails and test1 passes, BIT[15:14] is 'b01 if test0 fails and test1 fails, BIT[15:14] is 'b10 if test0 passes and test1 fails, BIT[15:14] is 'b11 if test0 passes and test1 passes, BIT[15:14] is 'b00 Synopsys STAR 9001202023: Wrong microframe number for isochronous IN endpoints.

Since it's an old interface, changing would require changing many call sites. So instead we create our own ext4_sb_bread(), which also allows us to set the REQ_META flag. Also fixed a problem in the xattr code where a NULL return in a function could also mean that the xattr was not found, which could lead to the wrong error getting returned to userspace.

Miller commit 40b1c813ba8e0aac9ee36b57f2835777506084c6 Author: Colin Ian King Date: Sun Nov 25 16:08:51 2018 +0000 net: bridge: remove redundant checks for null p->dev and p->br A recent change added a null check on p->dev after p->dev was being dereferenced by the ns_capable check on p->dev. It turns out that neither the p->dev and p->br null checks are necessary, and can be removed, which cleans up a static analyis warning. As Nikolay Aleksandrov noted, these checks can be removed because: "My reasoning of why it shouldn't be possible: - On port add new_nbp() sets both p->dev and p->br before creating kobj/sysfs - On port del (trickier) del_nbp() calls kobject_del() before call_rcu() to destroy the port which in turn calls sysfs_remove_dir() which uses kernfs_remove() which deactivates (shouldn't be able to open new files) and calls kernfs_drain() to drain current open/mmaped files in the respective dir before continuing, thus making it impossible to open a bridge port sysfs file with p->dev and p->br equal to NULL. So I think it's safe to remove those checks altogether. It'd be nice to get a second look over my reasoning as I might be missing something in sysfs/kernfs call path." Thanks to Nikolay Aleksandrov's suggestion to remove the check and David Miller for sanity checking this.

With such name, the directory creation (silently) fails and the debugfs entry ends up being created at the debugfs root. With this change, the new clock names are: - c1108680.adc#adc_div - c1108680.adc#adc_en This matches the clock naming scheme used in the PWM, Ethernet and MMC drivers. It also fixes the problem with debugfs. The idea is shamelessly taken from commit b96e9eb62841c5 ("pwm: meson: Fix mux clock names").

If the register allocated by the compiler happens to be zero (r0), it might cause an invalid memory address access, since load and store operations consider the content of 0x0 address if the base register is r0, instead of the content of the r0 register. For example: r1 := 0xdeadbeef r0 := 0xdeadbeef ld r2, 0(1) /* will load into r2 the content of r1 address */ ld r2, 0(0) /* will load into r2 the content of 0x0 */ In order to avoid this possible problem, the inline assembly constraint should be aware that these registers will be used as a base register, thus, r0 should not be allocated. Other than that, this patch removes inline assembly operands that are not used by the tests.

Before commit 5cd8d46ea156 ("packet: copy user buffers before orphan or clone") ring slots could be released prematurely, possibly allowing a process to overwrite data still in flight. This test opens two packet sockets, one to send and one to read. The sender has a tx ring of one slot. It sends two packets with different payload, then reads both and verifies their payload. Before the above commit, both receive calls return the same data as the send calls use the same buffer. From the commit, the clone needed for looping onto a packet socket triggers an skb_copy_ubufs to create a private copy. The separate sends each arrive correctly.

Miller Date: Fri Nov 23 18:02:24 2018 -0800 Merge branch 'switchdev-blocking-notifiers' Petr Machata says: ==================== switchdev: Convert switchdev_port_obj_{add,del}() to notifiers An offloading driver may need to have access to switchdev events on ports that aren't directly under its control. An example is a VXLAN port attached to a bridge offloaded by a driver. The driver needs to know about VLANs configured on the VXLAN device. However the VXLAN device isn't stashed between the bridge and a front-panel-port device (such as is the case e.g. for LAG devices), so the usual switchdev ops don't reach the driver. VXLAN is likely not the only device type like this: in theory any L2 tunnel device that needs offloading will prompt requirement of this sort. A way to fix this is to give up the notion of port object addition / deletion as a switchdev operation, which assumes somewhat tight coupling between the message producer and consumer. And instead send the message over a notifier chain. The series starts with a clean-up patch #1, where SWITCHDEV_OBJ_PORT_{VLAN, MDB}() are fixed up to lift the constraint that the passed-in argument be a simple variable named "obj". switchdev_port_obj_add and _del are invoked in a context that permits blocking. Not only that, at least for the VLAN notification, being able to signal failure is actually important. Therefore introduce a new blocking notifier chain that the new events will be sent on. That's done in patch #2. Retain the current (atomic) notifier chain for the preexisting notifications. In patch #3, introduce two new switchdev notifier types, SWITCHDEV_PORT_OBJ_ADD and SWITCHDEV_PORT_OBJ_DEL. These notifier types communicate the same event as the corresponding switchdev op, except in a form of a notification. struct switchdev_notifier_port_obj_info was added to carry the fields that correspond to the switchdev op arguments. An additional field, handled, will be used to communicate back to switchdev that the event has reached an interested party, which will be important for the two-phase commit. In patches #4, #5, and #7, rocker, DSA resp. ethsw are updated to subscribe to the switchdev blocking notifier chain, and handle the new notifier types. #6 introduces a helper to determine whether a netdevice corresponds to a front panel port. What these three drivers have in common is that their ports don't support any uppers besides bridge. That makes it possible to ignore any notifiers that don't reference a front-panel port device, because they are certainly out of scope. Unlike the previous three, mlxsw and ocelot drivers admit stacked devices as uppers. While the current switchdev code recursively descends through layers of lower devices, eventually calling the op on a front-panel port device, the notifier would reference a stacking device that's one of front-panel ports uppers. The filtering is thus more complex. For ocelot, such iteration is currently pretty much required, because there's no bookkeeping of LAG devices. mlxsw does keep the list of LAGs, however it iterates the lower devices anyway when deciding whether an event on a tunnel device pertains to the driver or not. Therefore this patch set instead introduces, in patch #8, a helper to iterate through lowers, much like the current switchdev code does, looking for devices that match a given predicate. Then in patches #9 and #10, first mlxsw and then ocelot are updated to dispatch the newly-added notifier types to the preexisting port_obj_add/_del handlers. The dispatch is done via the new helper, to recursively descend through lower devices. Finally in patch #11, the actual switch is made, retiring the current SDO-based code in favor of a notifier. Now that the event is distributed through a notifier, the explicit netdevice check in rocker, DSA and ethsw doesn't let through any events except those done on a front-panel port itself. It is therefore unnecessary to check in VLAN-handling code whether a VLAN was added to the bridge itself: such events will simply be ignored much sooner. Therefore remove it in patch #12. ==================== Signed-off-by: David S.

The logic to do so is fairly repetitive: each driver is looking for its own devices among the lowers of the notified device. For those that it finds, it calls a handler. To indicate that the event was handled, struct switchdev_notifier_port_obj_info.handled is set. The differences lie only in what constitutes an "own" device and what handler to call. Therefore abstract this logic into two helpers, switchdev_handle_port_obj_add() and switchdev_handle_port_obj_del(). If a driver only supports physical ports under a bridge device, it will simply avoid this layer of indirection. One area where this helper diverges from the current switchdev behavior is the case of mixed lowers, some of which are switchdev ports and some of which are not. Previously, such scenario would fail with -EOPNOTSUPP. The helper could do that for lowers for which the passed-in predicate doesn't hold. That would however break the case that switchdev ports from several different drivers are stashed under one master, a scenario that switchdev currently happily supports. Therefore tolerate any and all unknown netdevices, whether they are backed by a switchdev driver or not. Signed-off-by: Petr Machata Reviewed-by: Ido Schimmel Signed-off-by: David S.

Additionally, instead of passing "OBJ" to container_of() verbatim, parenthesize it, so that a comma in the passed-in expression doesn't pollute the container_of() invocation.

Lee Date: Fri Nov 23 07:14:32 2018 +0900 samples: bpf: fix: error handling regarding kprobe_events Currently, kprobe_events failure won't be handled properly. Due to calling system() indirectly to write to kprobe_events, it can't be identified whether an error is derived from kprobe or system. // buf = "echo '%c:%s %s' >> /s/k/d/t/kprobe_events" err = system(buf); if (err < 0) { printf("failed to create kprobe .."); return -1; } For example, running ./tracex7 sample in ext4 partition, "echo p:open_ctree open_ctree >> /s/k/d/t/kprobe_events" gets 256 error code system() failure. => The error comes from kprobe, but it's not handled correctly. According to man of system(3), it's return value just passes the termination status of the child shell rather than treating the error as -1. (don't care success) Which means, currently it's not working as desired. (According to the upper code snippet) ex) running ./tracex7 with ext4 env. # Current Output sh: echo: I/O error failed to open event open_ctree # Desired Output failed to create kprobe 'open_ctree' error 'No such file or directory' The problem is, error can't be verified whether from child ps or system. But using write() directly can verify the command failure, and it will treat all error as -1. So I suggest using write() directly to 'kprobe_events' rather than calling system().

Demultiplexing of the states from the packets is done in software interrupt context regardless of any process context. In a view of userspace applications, it needs to have notification mechanism to catch change of the states. This commit implements a queue to store events for the notification. The image of states includes fluctuating data such as level of gain/volume for physical input/output and position of knobs. Therefore the events are queued corresponding to some control features only. Furthermore, the queued events are planned to be consumed by userspace applications via ALSA hwdep interface. This commit suppresses event queueing when no applications open the hwdep interface. However, the queue is maintained in an optimistic scenario, thus without any care against overrrun. This is reasonable because target events are useless just to handle PCM frames. It starts queueing when an usespace application opens hwdep interface, thus it's expected to read the queued events steadily.

The public S805 datasheet states that this should be set to 1 to disable the clock, the default value is 0. There is also a hint that these are "just in case" bits which only exist in case the corresponding mux implementation does not allow glitch-free parent changes (the muxes are designed in a way that the clock can stay enabled when changing the mux). It's still good practise to describe this clock even if we're not supposed to modify it. Thus this uses the read-only gate ops.

Examples are the ABP, PERIPH, AXI and L2 DRAM clocks on Meson8b. The datasheet suggests that these bits are not touched. The full explanation is: "Set to 1 to manually disable the [...] clock when changing the mux selection. Typically this bit is set to 0 since the clock muxes can switch without glitches.". This adds new read-only ops for gate clocks so we can describe these clocks in our clock controller drivers while ensuring that we can't accidentally modify the registers.

This is achieved by using M = 66, N = 1 (24MHz * 66 / 1). At boot the CPU clock is running off sys_pll divided by 2 which results in 792MHz. Thus M = 66 is considered to be a "safe" value for Meson8b. To achieve 1608MHz (one of the CPU OPPs on Meson8 and Meson8m2) we need M = 67, N = 1. I ran "stress --cpu 4" while infinitely cycling through all available frequencies on my Meson8m2 board and could not spot any issues with this setting (after ~12 hours of running this). On Meson8, Meson8b and Meson8m2 we also want to be able to use 408MHz and 816MHz CPU frequencies. These can be achieved by dividing sys_pll by 4 (for 408MHz) or 2 (for 816MHz). That means that sys_pll has to run at 1632MHz which can be generated using M = 68, N = 1. Similarily we also want to be able to use 1008MHz as CPU frequency. This means that sys_pll has to run either at 1008MHz or 2016MHz. The former would result in an M value of 42, which is lower than the smallest value used by the 3.10 GPL kernel sources from Amlogic (50 is the lower limit there). Thus we need to run sys_pll at 2016MHz which can ge generated using M = 84, N = 1. I tested M = 68 and M = 84 on my Meson8b Odroid-C1 and my Meson8m2 board by running "stress --cpu 4" while infinitely cycling thorugh all available frequencies. I could not spot any issues after ~12 hours of running this. Amlogic's 3.10 GPL kernel sources have more M/N combinations. I did not add them yet because M = 74 (to achieve close to 1800MHz on Meson8) and M = 82 (to achieve close to 1992MHz on Meson8 as well) caused my Meson8m2 board to hang randomly. It's not clear why this is (for example because the board's voltage regulator design is bad, some missing bits for these values in our clk-pll driver, etc.). Thus the following M values from the Amlogic 3.10 GPL kernel sources are skipped as of now: 69, 70, 71, 72, 73, 74, 76, 78, 80, 82, 84, 86, 88, 90, 92, 94, 96, 98 Signed-off-by: Martin Blumenstingl Acked-by: Jerome Brunet Signed-off-by: Neil Armstrong Link: https://lkml.kernel.org/r/20181115224048.13511-5-martin.blumenstingl@googlemail.com commit 0dad1ec65bc30a549aba38d34a727309bbf41bc8 Author: Martin Blumenstingl Date: Thu Nov 15 23:40:45 2018 +0100 clk: meson: meson8b: mark the CPU clock as CLK_IS_CRITICAL We don't want the common clock framework to disable the "cpu_clk" if it's not used by any device. The cpufreq-dt driver does not enable the CPU clocks. However, even if it would we would still want the CPU clock to be enabled at all times because the CPU clock is also required even if we disable CPU frequency scaling on a specific board. The reason why we want the CPU clock to be enabled is a clock further up in the tree: Since commit 6f888e7bc7bd58 ("clk: meson: clk-pll: add enable bit") the sys_pll can be disabled. However, since the CPU clock is derived from sys_pll we don't want sys_pll to get disabled. The common clock framework takes care of that for us by enabling all parent clocks of our CPU clock when we mark the CPU clock with CLK_IS_CRITICAL. Until now this is not a problem yet because all clocks in the CPU clock's tree (including sys_pll) are read-only. However, once we allow modifications to the clocks in that tree we will need this.

Currently meson_clk_pll_enable unconditionally resets the PLL, enables it, takes it out of reset and waits until it is locked. This works fine for our current clock trees. However, there will be a problem once we allow modifications to sys_pll on Meson8, Meson8b and Meson8m2 (which will be required for CPU frequency scaling): the CPU clock is derived from the sys_pll clock. Once clk_enable is called on the CPU clock this will be propagated by the common clock framework up until the sys_pll clock. If we reset the PLL unconditionally in meson_clk_pll_enable the CPU will be stopped (on Meson8, Meson8b and Meson8m2). To prevent this we simply check if the PLL is already enabled and do reset the PLL if it's already enabled and locked. Now that we have a utility function to check whether the PLL is enabled we can also pass that to our clk_ops to let the common clock framework know about the status of the hardware clock. For now this is of limited use since the only common clock framework's internal "disabled unused clocks" mechanism checks for this. Everything else still uses the ref-counting (internal to the common clock framework) when clk_enable is called.

This matches the code in Amlogic's 3.10 GPL kernel sources: N = (aml_read_reg32(P_HHI_SYS_CPU_CLK_CNTL1) >> 20) & 0x3FF; This means that the divider register is 10 bit wide instead of 9 bits. So far this is not a problem since all u-boot versions I have seen are not using the cpu_scale_div clock at all (instead they are configuring the CPU clock to run off cpu_in_sel directly). The fixes tag points to the latest rework of the CPU clocks. However, even before the rework it was wrong. Commit 7a29a869434e8b ("clk: meson: Add support for Meson clock controller") defines MESON_N_WIDTH as 9 (in drivers/clk/meson/clk-cpu.c).

Unfortunately it does not mention how to use the register contents. The Amlogic 3.10 GPL kernel sources are using the following code to calculate the CPU clock based on that register (taken from arch/arm/mach-meson8/clock.c in the 3.10 Amlogic kernel, shortened to make it easier to read): N = (aml_read_reg32(P_HHI_SYS_CPU_CLK_CNTL1) >> 20) & 0x3FF; if (sel == 3) /* use cpu_scale_div */ div = 2 * N; else div = ... /* not relevant for this example */ cpu_clk = parent_clk / div; This suggests that the formula is: parent_rate / 2 * register_value However, running perf (which can measure the CPU clock rate thanks to the ARM PMU) shows that this formula is not correct. This can be reproduced with the following steps: 1. boot into u-boot 2. let the CPU clock run off the XTAL clock: mw.l 0xC110419C 0x30 1 3. set the cpu_scale_div register: to value 0x1: mw.l 0xC110415C 0x801016A2 1 to value 0x2: mw.l 0xC110415C 0x802016A2 1 to value 0x5: mw.l 0xC110415C 0x805016A2 1 4. let the CPU clock run off cpu_scale_div: mw.l 0xC110419C 0xbd 1 5. boot Linux 6. run: perf stat -aB stress --cpu 4 --timeout 10 7. check the "cycles" value I get the following results depending on the cpu_scale_div value: - (cpu_in_sel - this is the input clock for cpu_scale_div - runs at 1.2GHz) - 0x1 = 300MHz - 0x2 = 200MHz - 0x5 = 100MHz This means that the actual formula to calculate the output of the cpu_scale_div clock is: parent_rate / 2 * (register value + 1). The register value 0x0 is reserved. When letting the CPU clock run off the cpu_scale_div while the value is 0x0 the whole board hangs (even in u-boot). I also verified this with the TWD timer: when adding this to the .dts without specifying it's clock it will auto-detect the PERIPH (which is the input clock of the TWD) clock rate (and the result is shown in the kernel log). On Meson8, Meson8b and Meson8m2 the PERIPH clock is CPUCLK divided by 4. This also matched for all three test-cases from above (in all cases the TWD timer clock rate was approx. one fourth of the CPU clock rate). A small note regarding the "fixes" tag: the original issue seems to exist virtually since forever. Even commit 28b9fcd016126e ("clk: meson8b: Add support for Meson8b clocks") seems to handle this wrong. I still decided to use commit 251b6fd38bcb9c ("clk: meson: rework meson8b cpu clock") because this is the first commit which gets the CPU hiearchy correct and thus it's the first commit where the cpu_scale_div register is used correctly (apart from the bug in the cpu_scale_table).

We do try to window the string and only capture the portion that is being read, but that means that we must always convert up to the window to find the start. For a very large error state bordering on EXEC_OBJECT_CAPTURE abuse, this is noticeable as it degrades to O(N^2)!

This will become somewhat easy to hit on SKL+ once we start to add all the planes for the crtc to every modeset commit for the purposes of forcing a watermark register programming [1]. To make the race a little less pronounced let's complete fake_commit->flip_done after drm_atomic_helper_wait_for_flip_done(). For the single crtc case this should make the race quite theoretical, assuming drm_atomic_helper_wait_for_flip_done() actually has to wait for the real commit flip_done. In case the real commit flip_done gets completed singificantly before drm_atomic_helper_wait_for_flip_done(), or we are dealing with multiple crtcs whose vblanks don't line up nicely the race still exists.

This is different behavior than for other memory types and prevents us from deallocating buffers in following two cases: 1) There are outstanding mmap()ed views on the buffer. However even if we put the buffer in reqbufs(0), there will be remaining references, due to vma .open/close() adjusting vb2 buffer refcount appropriately. This means that the buffer will be in fact freed only when the last mmap()ed view is unmapped. 2) Buffer has been exported as a DMABUF. Refcount of the vb2 buffer is managed properly by VB2 DMABUF ops, i.e. incremented on DMABUF get and decremented on DMABUF release. This means that the buffer will be alive until all importers release it. Considering both cases above, there does not seem to be any need to prevent reqbufs(0) operation, because buffer lifetime is already properly managed by both mmap() and DMABUF code paths. Let's remove it and allow userspace freeing the queue (and potentially allocating a new one) even though old buffers might be still in processing. To let userspace know that the kernel now supports orphaning buffers that are still in use, add a new V4L2_BUF_CAP_SUPPORTS_ORPHANED_BUFS to be set by reqbufs and create_bufs.

This happened both with 'real' hardware and with the vivid CEC emulation, suggesting that this was an issue in the core code that claims a logical address. What 'cec-ctl --playback' does is to first clear all existing logical addresses, and immediately after that configure the new desired device type. The core code will poll the logical addresses trying to find a free address. When found it will issue a few standard messages as per the CEC spec and return. Those messages are queued up and will be transmitted asynchronously. What happens is that if you run two 'cec-ctl --playback' commands in quick succession, there is still a message of the first cec-ctl command being transmitted when you reconfigure the adapter again in the second cec-ctl command. When the logical addresses are cleared, then all information about outstanding transmits inside the CEC core is also cleared, and the core is no longer aware that there is still a transmit in flight. When the hardware finishes the transmit it calls transmit_done and the CEC core thinks it is actually in response of a POLL messages that is trying to find a free logical address. The result of all this is that the core thinks that the logical address for Playback Device 1 is in use, when it is really an earlier transmit that ended. The main transmit thread looks at adap->transmitting to check if a transmit is in progress, but that is set to NULL when the adapter is unconfigured. adap->transmitting represents the view of userspace, not that of the hardware. So when unconfiguring the adapter the message is marked aborted from the point of view of userspace, but seen from the PoV of the hardware it is still ongoing. So introduce a new bool transmit_in_progress that represents the hardware state and use that instead of adap->transmitting. Now the CEC core waits until the hardware finishes the transmit before starting a new transmit.

This means that the buffer is way oversized for the average stream to the extend that it will hold a few hundred frames when the video data is compressing well. The current strategy of queueing as much bitstream data as possible leads to large delays when draining the decoder. In order to keep the drain latency to a reasonable bound, try to only queue a full reorder window of buffers. We can't always hit this low target for very well compressible video data, as we might end up with less than the minimum amount of data that needs to be available to the bitstream prefetcher, so we must take this into account and allow more buffers to be queued in this case.

For the decoder to see data up to a desired position in the next run, the bitstream has to be filled for 2 256 byte blocks past that position aligned up to the next 256 byte boundary. This should make sure we never run into a buffer underrun condition if userspace does not supply new input buffers fast enough.

The removed FIXME was asking to manually train the link but we don't need to do that as by spec sink should do a short pulse when it is out of sync with source, we just need to make sure it is awaken and the SDP header with PSR inactive set it will trigger the short pulse with a error set in the link status. v3: added workarround to fix scheduled work starvation cause by to frequent PSR error interruption v4: only setting irq_aux_error as we don't care in clear it and not using dev_priv->irq_lock as consequence. v5: rebased: using edp_psr_shift() Cc: Dhinakaran Pandiyan Reviewed-by: Rodrigo Vivi Signed-off-by: José Roberto de Souza Link: https://patchwork.freedesktop.org/patch/msgid/20181121225441.18785-4-jose.souza@intel.com commit 50a12d8fc9a0d687d9ef4ac9cc16d177a2529937 Author: José Roberto de Souza Date: Wed Nov 21 14:54:38 2018 -0800 drm/i915: Do not enable PSR in the next modeset after a error When we detect a error and disable PSR, it is kept disabled until the next modeset but as the sink already show signs that it do not properly work with PSR lets disabled it for good to avoid any additional flickering.

So in the short pulse handling it was returning earlier and doing a full detection and attempting to retrain but it fails as PSR HW is in change of the main-link. Just call intel_psr_short_pulse() before intel_dp_needs_link_retrain() is not the right fix as intel_dp_needs_link_retrain() would return true and trigger a full detection while PSR HW is still in change of main-link.

But intel_dp_short_pulse() compares the old count with the read one if there is a mistmatch a full port detection will be executed, what was happening in the first short pulse interruption of eDP panels that sets sink count. Instead of just skip the compasison for eDP panels, lets not read the sink count at all for eDP. v2: the previous version of this patch it was caching the sink count in intel_edp_init_dpcd() but I was pointed out by Ville a patch that handled a case of a eDP panel that do not set sink count and as sink count is not used to eDP certification was choosed to just not read it at all.

Kernel core device reference count is not sufficient, as this only keeps the structure valid, and doesn't guarantee the driver is still loaded. Similar race can occur with device renaming and device removal, where device_rename() tries to rename a unregistered device. While this is fine for devices of a class which are not net namespace aware, but it is incorrect for net namespace aware class coming in subsequent series. If a class is net namespace aware, then the below [1] call trace is observed in above situation. Therefore, to avoid the race, keep a reference count and let device unregistration wait until all netlink users drop the reference.

Separate those functions and add those as vendor specific functions. The major difference is in MBA feature: - AMD uses CPUID leaf 0x80000020 to initialize the MBA features. - AMD uses direct bandwidth value instead of delay based on bandwidth values. - MSR register base addresses are different for MBA. - AMD allows non-contiguous L3 cache bit masks.

The command path is reworked to use uapi instead of its internal structures. The command mask is moved from a runtime check to a registration time check in the uapi. Since the write interface does not have the object ID as part of the command, the radix bins are converted into linear lists to support the lookup.

Remove it from the uverbs_uapi in this case. This also disables methods of other objects that have mandatory object handle inputs - ie REG_DM_MR is now automatically removed if DM objects cannot be created. Typically drivers not supporting an interface will mark all of the supporting functions as NULL, including destroy. This is intended to automatically eliminate entire corner cases in the API that are difficult to test.

It is best to reflect this directly into the struct uverbs_api when it is built so that everything is simply blocked off, and future introspection can report a proper supported list. This is done by adding some additional helpers to the definition list language that disable objects based on a 'supported' call back, and a helper that disables based on a NULL struct ib_device function pointer. Disablement is global. For instance, if a driver disables an object then everything connected to that object is removed, including core methods.

The new radix tree based compiler can handle a more complex input language that does not require the compiler to perfectly group everything into a neat tree structure. Instead use a simple list to describe to input, where the list elements can be of various different 'opcodes' instructing the radix compiler what to do. Start out with opcodes chaining to other definition lists and chaining to the existing 'tree' definition. Replace the very top level of the 'object tree' with this list type and get rid of struct uverbs_object_tree_def and DECLARE_UVERBS_OBJECT_TREE.

However there is an implicit assumption in the code that domain's adjusted guest address width (agaw) would always be greater than IOMMU's agaw. The IOMMU capabilities in an upcoming platform cause the domain's agaw to be lower than IOMMU's agaw. The issue is seen when the IOMMU supports both 4-level and 5-level paging. The domain builds a 4-level page table based on agaw of 2. However the IOMMU's agaw is set as 3 (5-level). In this case the code incorrectly tries to skip page page table levels. This causes the IOMMU driver to avoid programming the context entry. The fix handles this case and programs the context entry accordingly.

This is a bit of a waste of time. A child regulator already refcounts its own enables so it should avoid passing on to its parent unless the refcount transitioned between 0 and 1. Historically this hasn't been a huge problem since we skipped dealing with enable for always-on regulators. In a previous patch, however, we removed the always-on optimization. On one system, the debugfs regulator_summary was now showing a "use_count" of 33 for a top-level regulator. Let's implement this optimization. This turns out to be fairly trivial with the recent reorganization of the regulator core. NOTE: as part of this patch I'll make "always-on" regulators start with a use count of 1. This keeps the counts clean when recursively resolving regulators. ALSO NOTE: this commit also contains somewhat of a bug fix to regulator_force_disable(). It was incorrectly looping over "rdev->open_count" when it should have been looping over use_count. We have to touch that code anyway (since we should no longer loop at all), so we'll fix it together in one patch. Also: since this comes after commit f8702f9e4aa7 ("regulator: core: Use ww_mutex for regulators locking") we can now move to use _regulator_disable() for our supply and keep it in the lock.

Up to this point the regulator framework has continued to count a consumer's load request for disabled regulators. This has led to code patterns that look like this: enable_my_thing(): regular_set_load(reg, load_uA) regulator_enable(reg) disable_my_thing(): regulator_disable(reg) regulator_set_load(reg, 0) Sometimes disable_my_thing() sets a nominal (<= 100 uA) load instead of setting a 0 uA load. I will make the assertion that nearly all (if not all) places where we set a nominal load of 100 uA or less we end up with a result that is the same as if we had set a load of 0 uA. Specifically: - The whole point of setting the load is to help set the operating mode of the regulator. Higher loads may need less efficient operating modes. - The only time this matters at all is if there is another consumer of the regulator that wants the regulator on. If there are no other consumers of the regulator then the regulator will turn off and we don't care about the operating mode. - If there's another consumer that actually wants the regulator on then presumably it is requesting a load that makes our nominal <= 100 uA load insignificant.

Therefore, some of serial consoles drivers are re-entrant. E.g. 8250: serial8250_console_write() { if (port->sysrq) locked = 0; else if (oops_in_progress) locked = spin_trylock_irqsave(&port->lock, flags); else spin_lock_irqsave(&port->lock, flags); ... } panic() does set oops_in_progress via bust_spinlocks(1), so in theory we should be able to re-enter serial console driver from panic(): CPU0 uart_console_write() serial8250_console_write() // if (oops_in_progress) // spin_trylock_irqsave() call_console_drivers() console_unlock() console_flush_on_panic() bust_spinlocks(1) // oops_in_progress++ panic() spin_lock_irqsave(&port->lock, flags) // spin_lock_irqsave() serial8250_console_write() call_console_drivers() console_unlock() printk() ... However, this does not happen and we deadlock in serial console on port->lock spinlock. And the problem is that console_flush_on_panic() called after bust_spinlocks(0): void panic(const char *fmt, ...) { bust_spinlocks(1); ... bust_spinlocks(0); console_flush_on_panic(); ... } bust_spinlocks(0) decrements oops_in_progress, so oops_in_progress can go back to zero. Thus even re-entrant console drivers will simply spin on port->lock spinlock. Given that port->lock may already be locked either by a stopped CPU, or by the very same CPU we execute panic() on (for instance, NMI panic() on printing CPU) the system deadlocks and does not reboot. Fix this by removing bust_spinlocks(0), so oops_in_progress is always set in panic() now and, thus, re-entrant console drivers will trylock the port->lock instead of spinning on it forever, when we call them from console_flush_on_panic().

When the nds32 FPU finds the result of the instruction is a denormlized number, the nds32 FPU considers it to be an underflow condition and rounds the result to an appropriate number. It may causes some loss of precision. This commit proposes a solution to re-execute the instruction by the FPU emulator to enhance the precision. To transfer calculations from user space to kernel space, this feature will enable the underflow exception trap by default. Enabling this feature may cause some side effects: 1. Performance loss due to extra FPU exception 2. Need another scheme to control real underflow trap A new parameter, UDF_trap, which is belong to FPU context is used to control underflow trap. User can configure this feature via CONFIG_SUPPORT_DENORMAL_ARITHMETIC Signed-off-by: Vincent Chen Acked-by: Greentime Hu Signed-off-by: Greentime Hu commit 1ac832509f2ea1b566f0c06f98f308f58b03d098 Author: Vincent Chen Date: Thu Nov 22 11:14:35 2018 +0800 nds32: Support FP emulation The Andes FPU coprocessor does not support denormalized number handling. According to the specification, FPU generates a denorm input exception that requires the kernel to deal with this instrution operation when it encounters denormalized operands. Hence an nds32 FPU ISA emulator in the kernel is required to meet requirement.

This is especially true with the kernel image when it is compiled this way, which is the arm64 default since the patcheset "Enable deadcode elimination at link time". Perf organize maps using a rbtree. Whenever perf finds a new symbols, it first searches this rbtree for the map it belongs to, by strcmp()'aring section names. When it finds the map with the right name, it uses it to add the symbol. With a usual image there aren't so many maps but when using -ffunction-section there's basically one map per function. With the kernel image that's north of 40,000 maps. For most symbols perf has to parses the entire rbtree to eventually create a new map and add it. Consequently perf spends most of the time browsing a rbtree that keeps getting larger. This performance fix introduces a secondary rbtree that indexes maps based on the section name.

Mark cmlr code in jvmti/libjvmti.c with HAVE_JVMTI_CMLR, so we can compile it on system without cmlr support. This change makes the jvmti compile with java-1.8.0-ibm package.

Because the Cascadelake server and the Skylake server have the same CPU model number, which are used by the perf tools to find the event list. The stepping for Skylake server is up to 4. The stepping for Cascadelake server starts from 5. The stepping can be used to distinguish between them. The stepping is added in get_cpuid_str(). The stepping information for Skylake server is updated in mapfile.csv. A x86 specific strcmp_cpuid_cmp() function is added to handle two CPUID formats in mapfile.csv, "vendor-family-model-stepping" and "vendor-family-model": - If a cpuid-regular-expression from the mapfile.csv using the new stepping format, a cpuid-string generated on the machine must include stepping. Otherwise, it is a mismatch. - If the cpuid-regular-expression using the old non-stepping format, the stepping in the cpuid-string will be ignored. The script, using environment string "PERF_CPUID" without stepping on Skylake server, will be broken. If so, users must fix their scripts.

Miller Date: Wed Nov 21 17:10:32 2018 -0800 Merge branch 'mlxsw-Add-VxLAN-learning-support' Ido Schimmel says: ==================== mlxsw: Add VxLAN learning support This patchset adds VxLAN learning support in the mlxsw driver. The first five patches from Petr add the required switchdev APIs which allow device drivers to notify the VxLAN driver about learned / aged-out FDB entries. First in patch #1, an unnecessary argument is dropped from __vxlan_fdb_delete(). In patches #2-#4, the VxLAN FDB handling code is extended to make sending the switchdev events configurable; to mark user-added entries as such; and to make sure HW-learned FDB entries do not take over user-added ones. Finally in patch #5, the necessary switchdev notifications are added and handled by VxLAN, similarly to how this is handled in the bridge driver. Patch #6 allows changing of the VxLAN's device ageing time since it is useful for the selftest in the last patch. Patch #7 adds support for querying bridge port flags of a given netdevice, as a new entry should not be learned and notified to the bridge driver in case learning is disabled on the bridge port. Next patches gradually add learning support in mlxsw. The last patch adds a new test case for VxLAN learning. ==================== Signed-off-by: David S.

One of the Intel drivers was already fixed (ixgbe). Upon looking at the Intel drivers as a whole, we are handling our polling and NAPI exit in a few different ways based on whether we have multiqueue and whether we have Tx cleanup included. Several drivers had the bug of exiting NAPI with return 0, which appears to mess up the accounting in the stack. Consolidate all the NAPI routines to do best known way of exiting and to just mostly look like each other. 1) check return code of napi_complete_done to control interrupt enable 2) return the actual amount of work done. 3) return budget immediately if need NAPI poll again Tested the changes on e1000e with a high interrupt rate set, and it shows about an 8% reduction in the CPU utilization when busy polling because we aren't re-enabling interrupts when we're about to be polled.

Commit 6147b1cf19651 ("scripts/setlocalversion: git: Make -dirty check more robust") tried to fix this by switching to git-status, but it overlooked the fact that git-status also writes to the .git directory of the source tree, which is definitely not kosher for an out-of-tree (O=) build. That is getting reverted. Fortunately, git-status now supports avoiding writing to the index via the --no-optional-locks flag, as of git 2.14. It still calculates an up-to-date index, but it avoids writing it out to the .git directory. So, let's retry the solution from commit 6147b1cf19651 using this new flag first, and if it fails, we assume this is an older version of git and just use the old git-diff-index method. It's hairy to get the 'grep -vq' (inverted matching) correct by stashing the output of git-status (you have to be careful about the difference betwen "empty stdin" and "blank line on stdin"), so just pipe the output directly to grep and use a regex that's good enough for both the git-status and git-diff-index version.

This patch fixes the issue by the following approach: 1) introduce 'struct blk_mq_ctxs' for holding .mq_kobj and managing all ctxs 2) free all allocated ctxs and the 'blk_mq_ctxs' instance in release handler of .mq_kobj 3) grab one ref of .mq_kobj before initializing each ctx->kobj, so that .mq_kobj is always released after all ctxs are freed. This patch fixes kernel panic issue during booting when DEBUG_KOBJECT_RELEASE is enabled.

To avoid this let's program something sensible into the LUT when we do the plane update. In the future I plan to add proper plane gamma enable readout so this is just a temporary measure.

This QXLCursorCmd command points to a QXLCursor instance (stored in vram too). However, while the QXLCursorCmd memory is pinned, the QXLCursor memory is not. When booting a recent Fedora to its login screen while monitoring the QXLCursorCmd QEMU holds, it's possible to see the QXLCursor memory becoming invalid shortly after boot. Pinning that memory ensures that that QXLCursor memory is not going to be moved by the guest kernel. Moving the pin/unpin to qxl_release_list_add()/qxl_release_free_list() would be a more generic fix. However, doing this quickly exhausts QXL video memory, so more fixing would be needed before this is workable.

With MSA, where vector registers are aliased with scalar FP data registers, those registers are 128 bits wide. Thus a new mechanism is required for userland to access those registers via ptrace. This patch introduces an NT_MIPS_MSA regset which provides, in this order: - The full 128 bits value of each vector register, in native endianness saved as though elements are doubles. That is, the format of each vector register is as would be obtained by saving it to memory using an st.d instruction. - The 32 bit scalar FP implementation register (FIR). - The 32 bit scalar FP control & status register (FCSR). - The 32 bit MSA implementation register (MSAIR). - The 32 bit MSA control & status register (MSACSR). The provision of the FIR & FCSR registers in addition to the MSA equivalents allows scalar FP context to be retrieved as a subset of the context available via this regset.

Since the largest PAGE_SIZE supported by MIPS kernels is 64KB, increase the alignment calculated by calc_vmlinuz_load_addr to 64KB.

Akeem updates the driver to determine whether or not to do auto-negotiation based on the VSI state. Bruce cleans up the control queue code to remove duplicate code. Take advantage of some compiler optimizations by making some structures constant, and also note that they cannot be modified. Cleaned up formatting issues and code comment that needed clarification. Fixed a potential NULL pointer dereference by adding a check. Jaroslaw adds a check to verify if memory was allocated or not. Yashaswini Raghuram fixes the driver to ensure we are not enabling the LAN_EN flag if the MAC in the MAC-VLAN is a unicast MAC, so that the unicast packets are not forwarded to the wire. Dave fixes the return value of ice_napi_poll() to be more useful in returning the work that was done and should only return 0 when no work was done.

There are several steps to accomplish this achievement. First is to rename some function names with a prefix to indicate chip specific function. Second is to move common code into header that can be shared. Last is to modify tag_ksz.c so that it can handle many tail tag formats used by different KSZ switch drivers. ksz_common.c will contain the common code used by all KSZ switch drivers. ksz9477.c will contain KSZ9477 code from the original ksz_common.c. ksz9477_spi.c is renamed from ksz_spi.c. ksz9477_reg.h is renamed from ksz_9477_reg.h. ksz_common.h is added to provide common code access to KSZ switch drivers. ksz_spi.h is added to provide common SPI access functions to KSZ SPI drivers. v4 - Patches were removed to concentrate on changing driver structure without adding new code. v3 - The phy_device structure is used to hold port link information - A structure is passed in ksz_xmit and ksz_rcv instead of function pointer - Switch offload forwarding is supported v2 - Initialize reg_mutex before use - The alu_mutex is only used inside chip specific functions v1 - Each patch in the set is self-contained - Use ksz9477 prefix to indicate KSZ9477 specific code ==================== Signed-off-by: David S.

The func_info_rec_size is introduced in the UAPI to specify struct bpf_func_info size passed from user space. This intends to make bpf_func_info structure growable in the future. If the kernel gets a different bpf_func_info size from userspace, it will try to handle user request with part of bpf_func_info it can understand. In this patch, kernel can understand struct bpf_func_info { __u32 insn_offset; __u32 type_id; }; If user passed a bpf func_info record size of 16 bytes, the kernel can still handle part of records with the above definition. If verifier agrees with function range provided by the user, the bpf_prog ksym for each function will use the func name provided in the type_id, which is supposed to provide better encoding as it is not limited by 16 bytes program name limitation and this is better for bpf program which contains multiple subprograms. The bpf_prog_info interface is also extended to return btf_id, func_info, func_info_rec_size and func_info_cnt to userspace, so userspace can print out the function prototype for each xlated function. The insn_offset in the returned func_info corresponds to the insn offset for xlated functions. With other jit related fields in bpf_prog_info, userspace can also print out function prototypes for each jited function.

Thermal zone algorithm operates with the numerical states for PWM setting. Each state is the index, defined in range from 0 to 10 and it's mapped to the relevant duty cycle value, which is written to PWM controller. With the current definition fan speed is set to 0% for state 0, 10% for state 1, and so on up to 100% for the maximum state 10. Some systems have limitation for the PWM speed minimum. For such systems PWM setting speed to 0% will just disable the ability to increase speed anymore and such device will be stall on zero speed. Cooling levels allow to configure state vector according to the particular system requirements. For example, if PWM speed is not allowed to be below 30%, cooling levels could be configured as 30%, 30%, 30%, 30%, 40%, 50% and so on.

Normally VIDIOC_G_CROP will return the CROP rectangle of a CAPTURE stream and the COMPOSE rectangle of an OUTPUT stream. The Samsung drivers do the opposite. Note that these drivers predate the selection API. If this 'QUIRK' flag is set, then the v4l2-ioctl core will swap the CROP and COMPOSE targets as well. That way backwards compatibility is ensured and we can convert the Samsung drivers to the selection API.

Consumer will have to perform the opposite costly operation. AFAIK nothing in tcp stack requests the dst after skb was stored in the backlog.

As the helper doesn't have the skip logic, when the first task to visit is a non-leader thread, it doesn't get skipped correctly as shown in the following example. # ps -L 2030 PID LWP TTY STAT TIME COMMAND 2030 2030 pts/0 Sl+ 0:00 ./test-thread 2030 2031 pts/0 Sl+ 0:00 ./test-thread # mkdir -p /sys/fs/cgroup/x/a/b # echo threaded > /sys/fs/cgroup/x/a/cgroup.type # echo threaded > /sys/fs/cgroup/x/a/b/cgroup.type # echo 2030 > /sys/fs/cgroup/x/a/cgroup.procs # cat /sys/fs/cgroup/x/a/cgroup.threads 2030 2031 # cat /sys/fs/cgroup/x/cgroup.procs 2030 # echo 2030 > /sys/fs/cgroup/x/a/b/cgroup.threads # cat /sys/fs/cgroup/x/cgroup.procs 2031 2030 The last read of cgroup.procs is incorrectly showing non-leader 2031 in cgroup.procs output. This can be fixed by updating css_task_iter_advance() to handle the first advance and css_task_iters_tart() to call css_task_iter_advance() instead of the inner helper. After the fix, the same commands result in the following (correct) result: # ps -L 2062 PID LWP TTY STAT TIME COMMAND 2062 2062 pts/0 Sl+ 0:00 ./test-thread 2062 2063 pts/0 Sl+ 0:00 ./test-thread # mkdir -p /sys/fs/cgroup/x/a/b # echo threaded > /sys/fs/cgroup/x/a/cgroup.type # echo threaded > /sys/fs/cgroup/x/a/b/cgroup.type # echo 2062 > /sys/fs/cgroup/x/a/cgroup.procs # cat /sys/fs/cgroup/x/a/cgroup.threads 2062 2063 # cat /sys/fs/cgroup/x/cgroup.procs 2062 # echo 2062 > /sys/fs/cgroup/x/a/b/cgroup.threads # cat /sys/fs/cgroup/x/cgroup.procs 2062 Signed-off-by: Tejun Heo Reported-by: "Michael Kerrisk (man-pages)" Fixes: 8cfd8147df67 ("cgroup: implement cgroup v2 thread support") Cc: stable@vger.kernel.org # v4.14+ commit a929a42a3e7e8f8bebde51ead6742884782f6fcc Author: Federico Vaga Date: Fri Nov 9 00:24:17 2018 +0100 doc:it_IT:doc-guide: fix reference to foobar Replicate the following patch into italian translation 1bb37a35671c doc-guide:kernel-doc.rst: Reference to foobar Signed-off-by: Federico Vaga Signed-off-by: Jonathan Corbet commit 34523ec2f437eca4050862bfaead5b1fe3677f94 Author: Federico Vaga Date: Fri Nov 9 00:24:16 2018 +0100 doc:it_IT: fix locking.rst section title This title was still in English.

The mod->arch.{core,init}.plt pointers were problematic for livepatch because they pointed within temporary section headers (provided by the module loader via info->sechdrs) that would be freed after module load. Since livepatch modules may need to apply relocations post-module-load (for example, to patch a module that is loaded later), using section indices to offset into the section headers (instead of accessing them through a saved pointer) allows livepatch modules on arm64 to pass in their own copy of the section headers to apply_relocate_add() to apply delayed relocations.

However, this means that the entire region is mapped using read/write permissions, which we cannot modify at page granularity without having to take intrusive measures to prevent TLB conflicts. This means the linear aliases of pages belonging to read-only mappings (executable or otherwise) in the vmalloc region are also mapped read/write, and could potentially be abused to modify things like module code, bpf JIT code or other read-only data. So let's fix this, by extending the set_memory_ro/rw routines to take the linear alias into account. The consequence of enabling this is that we can no longer use block mappings or contiguous hints, so in cases where the TLB footprint of the linear region is a bottleneck, performance may be affected. Therefore, allow this feature to be runtime en/disabled, by setting rodata=full (or 'on' to disable just this enhancement, or 'off' to disable read-only mappings for code and r/o data entirely) on the kernel command line. Also, allow the default value to be set via a Kconfig option.

The normal code path for a page fault on a kernel address sanitizes the bit, but the paths for vsyscall emulation and SIGBUS do not. Both are harmless, but for subtle reasons. SIGBUS is never sent for a kernel address, and vsyscall emulation will never fault on a kernel address per se because it will fail an access_ok() check instead. Make the code more robust by adding a helper that sets the relevant fields and sanitizing the error code in the helper. This also cleans up the code -- we had three copies of roughly the same thing.

This can cause somewhat erratic behavior. The straightforward cases where the CPL agrees with the hardware USER bit are all correct, but the other cases are confusing. - A user instruction accessing a kernel address with supervisor privilege (e.g. a descriptor table access failed). The USER bit will be clear, and we OOPS. This is correct, because it indicates a kernel bug, not a user error. - A user instruction accessing a user address with supervisor privilege (e.g. a descriptor table was incorrectly pointing at user memory). __bad_area_nosemaphore() will be passed a modified error code with the user bit set, and we will send a signal. Sending the signal will work (because the regs and the entry frame genuinely come from user mode), but we really ought to OOPS, as this event indicates a severe kernel bug. - A kernel instruction with user privilege (i.e. WRUSS). This should OOPS or get fixed up. The current code would instead try send a signal and malfunction. Change the logic: a signal should be sent if the faulting context is user mode *and* the access has user privilege. Otherwise it's either a kernel mode fault or a failed implicit access, either of which should end up in no_context(). Note to -stable maintainers: don't backport this unless you backport CET. The bug it fixes is unobservable in current kernels unless something is extremely wrong.

This is incorrect -- the error has nothing to do with SMAP. Fix the condition so that only accesses with the hardware USER bit set are diagnosed as SMAP violations. With the logic fixed, an implicit supervisor access to a user address will hit the code lower in the function that is intended to handle it even if SMAP is enabled. That logic is still a bit buggy, and later patches will clean it up. I *think* this code is still correct for WRUSS, and I've added a comment to that effect.

Adiantum was designed by Paul Crowley and is specified by our paper: Adiantum: length-preserving encryption for entry-level processors (https://eprint.iacr.org/2018/720.pdf) See our paper for full details; this patch only provides an overview. Adiantum is a tweakable, length-preserving encryption mode designed for fast and secure disk encryption, especially on CPUs without dedicated crypto instructions. Adiantum encrypts each sector using the XChaCha12 stream cipher, two passes of an ε-almost-∆-universal (εA∆U) hash function, and an invocation of the AES-256 block cipher on a single 16-byte block. On CPUs without AES instructions, Adiantum is much faster than AES-XTS; for example, on ARM Cortex-A7, on 4096-byte sectors Adiantum encryption is about 4 times faster than AES-256-XTS encryption, and decryption about 5 times faster. Adiantum is a specialization of the more general HBSH construction. Our earlier proposal, HPolyC, was also a HBSH specialization, but it used a different εA∆U hash function, one based on Poly1305 only. Adiantum's εA∆U hash function, which is based primarily on the "NH" hash function like that used in UMAC (RFC4418), is about twice as fast as HPolyC's; consequently, Adiantum is about 20% faster than HPolyC. This speed comes with no loss of security: Adiantum is provably just as secure as HPolyC, in fact slightly *more* secure. Like HPolyC, Adiantum's security is reducible to that of XChaCha12 and AES-256, subject to a security bound. XChaCha12 itself has a security reduction to ChaCha12. Therefore, one need not "trust" Adiantum; one need only trust ChaCha12 and AES-256. Note that the εA∆U hash function is only used for its proven combinatorical properties so cannot be "broken". Adiantum is also a true wide-block encryption mode, so flipping any plaintext bit in the sector scrambles the entire ciphertext, and vice versa. No other such mode is available in the kernel currently; doing the same with XTS scrambles only 16 bytes. Adiantum also supports arbitrary-length tweaks and naturally supports any length input >= 16 bytes without needing "ciphertext stealing". For the stream cipher, Adiantum uses XChaCha12 rather than XChaCha20 in order to make encryption feasible on the widest range of devices. Although the 20-round variant is quite popular, the best known attacks on ChaCha are on only 7 rounds, so ChaCha12 still has a substantial security margin; in fact, larger than AES-256's. 12-round Salsa20 is also the eSTREAM recommendation. For the block cipher, Adiantum uses AES-256, despite it having a lower security margin than XChaCha12 and needing table lookups, due to AES's extensive adoption and analysis making it the obvious first choice. Nevertheless, for flexibility this patch also permits the "adiantum" template to be instantiated with XChaCha20 and/or with an alternate block cipher. We need Adiantum support in the kernel for use in dm-crypt and fscrypt, where currently the only other suitable options are block cipher modes such as AES-XTS. A big problem with this is that many low-end mobile devices (e.g. Android Go phones sold primarily in developing countries, as well as some smartwatches) still have CPUs that lack AES instructions, e.g. ARM Cortex-A7. Sadly, AES-XTS encryption is much too slow to be viable on these devices. We did find that some "lightweight" block ciphers are fast enough, but these suffer from problems such as not having much cryptanalysis or being too controversial. The ChaCha stream cipher has excellent performance but is insecure to use directly for disk encryption, since each sector's IV is reused each time it is overwritten. Even restricting the threat model to offline attacks only isn't enough, since modern flash storage devices don't guarantee that "overwrites" are really overwrites, due to wear-leveling. Adiantum avoids this problem by constructing a "tweakable super-pseudorandom permutation"; this is the strongest possible security model for length-preserving encryption. Of course, storing random nonces along with the ciphertext would be the ideal solution. But doing that with existing hardware and filesystems runs into major practical problems; in most cases it would require data journaling (like dm-integrity) which severely degrades performance. Thus, for now length-preserving encryption is still needed.

This is needed for Adiantum hashing, which builds an εA∆U hash function from NH and a polynomial evaluation in GF(2^{130}-5); this polynomial evaluation is identical to the one the Poly1305 MAC does. However, the crypto_shash Poly1305 API isn't very appropriate for this because its calling convention assumes it is used as a MAC, with a 32-byte "one-time key" provided for every digest. But by design, in Adiantum hashing the performance of the polynomial evaluation isn't nearly as critical as NH. So it suffices to just have some C helper functions. Thus, this patch adds such functions.

In more detail, the problem is that Adiantum is still much slower than we're happy with, and encryption still has a quite noticeable effect on the feel of low-end devices. Users and vendors push back hard against encryption that degrades the user experience, which always risks encryption being disabled entirely. So we need to choose the fastest option that gives us a solid margin of security, and here that's XChaCha12. The best known attack on ChaCha breaks only 7 rounds and has 2^235 time complexity, so ChaCha12's security margin is still better than AES-256's. Much has been learned about cryptanalysis of ARX ciphers since Salsa20 was originally designed in 2005, and it now seems we can be comfortable with a smaller number of rounds. The eSTREAM project also suggests the 12-round version of Salsa20 as providing the best balance among the different variants: combining very good performance with a "comfortable margin of security". Note that it would be trivial to add vanilla ChaCha12 in addition to XChaCha12. However, it's unneeded for now and therefore is omitted. As discussed in the patch that introduced XChaCha20 support, I considered splitting the code into separate chacha-common, chacha20, xchacha20, and xchacha12 modules, so that these algorithms could be enabled/disabled independently. However, since nearly all the code is shared anyway, I ultimately decided there would have been little benefit to the added complexity.

The justification for needing XChaCha12 support is explained in more detail in the patch "crypto: chacha - add XChaCha12 support". The only difference between ChaCha{8,12,20} are the number of rounds itself; all other parts of the algorithm are the same. Therefore, remove the "20" from all definitions, structures, functions, files, etc. that will be shared by all ChaCha versions. Also make ->setkey() store the round count in the chacha_ctx (previously chacha20_ctx). The generic code then passes the round count through to chacha_block(). There will be a ->setkey() function for each explicitly allowed round count; the encrypt/decrypt functions will be the same. I decided not to do it the opposite way (same ->setkey() function for all round counts, with different encrypt/decrypt functions) because that would have required more boilerplate code in architecture-specific implementations of ChaCha and XChaCha.

XChaCha20 is the application of the XSalsa20 construction (https://cr.yp.to/snuffle/xsalsa-20081128.pdf) to ChaCha20 rather than to Salsa20. XChaCha20 extends ChaCha20's nonce length from 64 bits (or 96 bits, depending on convention) to 192 bits, while provably retaining ChaCha20's security. XChaCha20 uses the ChaCha20 permutation to map the key and first 128 nonce bits to a 256-bit subkey. Then, it does the ChaCha20 stream cipher with the subkey and remaining 64 bits of nonce. We need XChaCha support in order to add support for the Adiantum encryption mode. Note that to meet our performance requirements, we actually plan to primarily use the variant XChaCha12. But we believe it's wise to first add XChaCha20 as a baseline with a higher security margin, in case there are any situations where it can be used. Supporting both variants is straightforward. Since XChaCha20's subkey differs for each request, XChaCha20 can't be a template that wraps ChaCha20; that would require re-keying the underlying ChaCha20 for every request, which wouldn't be thread-safe. Instead, we make XChaCha20 its own top-level algorithm which calls the ChaCha20 streaming implementation internally. Similar to the existing ChaCha20 implementation, we define the IV to be the nonce and stream position concatenated together. This allows users to seek to any position in the stream. I considered splitting the code into separate chacha20-common, chacha20, and xchacha20 modules, so that chacha20 and xchacha20 could be enabled/disabled independently. However, since nearly all the code is shared anyway, I ultimately decided there would have been little benefit to the added complexity of separate modules.

So far we have only supported the RED Qdisc offload, but we need a way to differentiate traffic types e.g. based on DSCP marking. It may seem like PRIO+RED is a good match for this job, however, (a) we don't need strict priority behaviour of PRIO, and (b) PRIO uses the legacy way of mapping ToS fields to bands, which is quite awkward and limitting. The less commonly used GRED Qdisc is a better much for the scenario, it allows multiple sets of RED parameters and queue lengths to be maintained with a single FIFO queue. This is exactly how nfp offload behaves. We use a trivial u32 classifier to assign packets to virtual queues. There is also the minor advantage that GRED can't have its child changed, therefore limitting ways in which the configuration of SW path can diverge from HW offload. Last patch of the series adds support for (G)RED in non-ECN mode, where packets are dropped instead of marked. ==================== Signed-off-by: David S.

First patch #1 fixes a bug in propagating SKB already-forwarded marks over veth to bridges, where they are irrelevant. This bug causes the vxlan_bridge_1d test suite from this patchset to fail as the packets aren't forwarded by br2. In patches #2 and #3, lib.sh is extended to support network namespaces. The use of namespaces is necessitated by VXLAN, which allows only one VXLAN device with a given VNI per namespace. Thus to host full topology on a single box for selftests, the "remote" endpoints need to be in namespaces. In patches #4-#6, lib.sh is extended in other ways to facilitate the following patches. In patches #7-#15, first the skeleton, and later the generic tests themselves are added. Patch #16 then adds another test that serves as a wrapper around the previous one, and runs it with a non-default port number. Patches #17 and #18 add mlxsw-specific tests. About those, Ido writes: The first test creates various configurations with regards to the VxLAN and bridge devices and makes sure the driver correctly forbids unsupported configuration and permits supported ones.

However then one can't use functions defined in lib.sh or a test suite. One option is to do "ip netns exec ns bash -c command", provided that all functions that one wishes to use (and their dependencies) are published using "export -f". That may not be practical. Therefore, introduce a helper in_ns(), which wraps a given command in a boilerplate of "ip netns exec" and "source lib.sh", thus making all library functions available. (Custom functions that a script wishes to run within a namespace still need to be exported.) Because quotes in "$@" aren't recognized in heredoc, hand-expand the array in an explicit for loop, leveraging printf %q to handle proper quoting.

There, since it ingresses the bridge over veth, which doesn't have offload_fwd_mark, it triggers a warning in nbp_switchdev_frame_mark(). Then nbp_switchdev_allowed_egress() decides not to allow egress from this bridge through another veth, because the SKB is already marked, and the mark (of 0) of course matches. Thus the packet is incorrectly blocked. Solve by resetting offload_fwd_mark() in skb_scrub_packet(). That function is called from tunnels and also from veth, and thus catches the cases where traffic is forwarded between bridges and transformed in a way that invalidates the marking.

This patchset adds logic for cleaning up of NPA, NIX and NPC block resources being used by PF. - Mailbox communication between AF and it's VFs. Unlike VFs of PF1-PFn, AF which is PF0 can communicate with it's VFs directly. Added support for the same. - AF's VFs IO configuration These VFs are mapped to use internal HW loopback channels instead of CGX LMACs. Each pair of VFs work as two of ends of hardwired interfaces. VF0's TX is VF1's Rx & viceversa. NPC block: - MCAM entry management Alloc/Free of contiguous/non-contiguous and lower/higher priority MCAM entry allocation and programming support. - MCAM counters management and map/unmap with MCAM entries - Default KEY extract profile - HW errata workarounds NIX block: - Minimum and maximum allowed packet length config - HW errata workarounds Few more changes like shift to use mutex instead of spinlock etc are done in this patchset. Changes from v2: 1 Fixed commit message of patch 'Relax resource lock into mutex' to a more unambiguous one. - Suggested by David Miller. Changes from v1: 1 Converted all mailbox message handler API names to small letters from mixed small and capital letters. - Suggested by David Miller. 2 Fixed endian issues in patch 'Add support for stripping STAG/CTAG' - Suggested by Arnd Bergmann 3 Elaborated commit message of patch 'Add FLR interrupt handler' to make it a bit more easy to understand. - Suggested by Arnd Bergmann Will fix the padding and alignment in mailbox message structure in a follow-up patch. ==================== Signed-off-by: David S.

This option takes the following structure, which specifies the association, the event type (using the same value found in the event type field), and an on/off boolean. struct sctp_event { sctp_assoc_t se_assoc_id; uint16_t se_type; uint8_t se_on; }; The user fills in the se_type field with the same value found in the strreset_type field, i.e., SCTP_STREAM_RESET_EVENT. The user will also fill in the se_assoc_id field with either the association to set this event on (this field is ignored for one-to-one style sockets) or one of the reserved constant values defined in [RFC6458]. Finally, the se_on field is set with a 1 to enable the event or a 0 to disable the event."

That way we'll have the same read/write/poll behavior as 4.20, and users that want to test/use polling are required to do manual configuration of the number of poll queues.

Normally, it's not a big issue as DPCD or EDID reads won't (hopefully) exceed that value. The real issue here is the revocation list read during the HDCP authentication process. (problematic use case: https://chromium.googlesource.com/chromiumos/third_party/kernel/+/chromeos-4.4/drivers/gpu/drm/rockchip/cdn-dp-reg.c#1152) The list can reach 127*5+4 bytes (num devs * 5 bytes per ID/Bksv + 4 bytes of an additional info).

We have to change the value of NR- _syscalls, if we add or delete a system call. One of the patch in this patch series has a script which will generate a uapi header based on syscall.tbl file. The syscall.tbl file contains the total number of system calls information. So we have two option to update NR_sy- scalls value. 1. Update NR_syscalls in asm/unistd.h manually by count- ing the no.of system calls. No need to update NR_sys- calls until we either add a new system call or delete existing system call. 2. We can keep this feature it above mentioned script, that will count the number of syscalls and keep it in a generated file. In this case we don't need to expli- citly update NR_syscalls in asm/unistd.h file. The 2nd option will be the recommended one. For that, I added the __NR_syscalls macro in uapi/asm/unistd.h along with NR_syscalls asm/unistd.h. The macro __NR_syscalls also added for making the name convention same across all architecture. While __NR_syscalls isn't strictly part of the uapi, having it as part of the generated header to simplifies the implementation. We also need to enclose this macro with #ifdef __KERNEL__ to avoid side effects. Signed-off-by: Firoz Khan Signed-off-by: David S.

Depending on the board layout and requirements we may want to re-configure the PHY to output the interrupt signal there. The mode of pin 21 can be configured in the "Digital I/O Specific Control Register" (register 29), bit 2: - 0 = RXER function - 1 = INTR(32) function Depending on the devicetree configuration we will now: - change the mode to either ther RXER or INTR32 function - keep the SEL_INTR32 value set by the bootloader (default) if no configuration is provided (to ensure that we're not breaking existing boards) - error out if conflicting configuration is given (RXER and INTR32 mode are enabled at the same time) Signed-off-by: Martin Blumenstingl Signed-off-by: David S.

Implement the .did_interrupt callback to let the PHY core know whether the interrupt was for this specific PHY. This is useful for debugging interrupt problems with 32-pin IP101GR PHYs where the interrupt line is shared with the RX_ERR (receive error status) signal. The default values are: - RX_ERR is enabled by default (LOW means that there is no receive error) - the PHY's interrupt line is configured "active low" by default Without any additional changes there is a flood of interrupts if the RX_ERR/INTR32 signal is configured in RX_ERR mode (which is the default). Having a did_interrupt ensures that the PHY core returns IRQ_NONE instead of endlessly triggering the PHY state machine.

IP101A/G PHYs The IP101A and IP101G series both have various models. Depending on the board implementation we need a special property for the IP101GR (32-pin LQFP package) PHY: pin 21 ("RXER/INTR_32") outputs the "receive error" signal by default (LOW means "normal operation", HIGH means that there's either a decoding error of the received signal or that the PHY is receiving LPI). This pin can also be switched to INTR32 mode, where the interrupt signal is routed to this pin. The other PHYs don't need this special handling because they have more pins available so the interrupt function gets a dedicated pin. This adds two properties to either select the "receive error" or "interrupt" function of pin 21. Not specifying any function means that the default set by the bootloader is used. This is required because the IP101GR cannot be differentiated between other IP101 PHYs as the PHY identification registers on all of these is 0x02430c54. The IP101G (sold as die only, without package) may suffer from the same issue depending on how it's integrated into a multi chip package by another manufacturer. If only the RXER/INTR_32 pin is routed then the users of the die-only variant may also have to explicitly configure the mode of hte RXER/INTR_32 pin. This is the reason why no "is-ip101gr" property was added. I have no evidence though which would confirm this theory - so the binding itself is independent of that.

Sparc was complicated by having a path_component_name in addition to full_name and name. By switching full_name to just the local node name, path_component_name becomes redundant and can be removed. The rest of the series converts the sparc code to use printf specifiers and helper functions to access node name and device_type instead of directly accessing device_node full_name, name and type pointers. I've tested this series under qemu. v2: - Add patch using of_node_name_eq for openpromfs - Add patch converting some resource names to full_name - Also drop full path on !Sparc PDT node name construction - Add a few missed %pOFn conversions ==================== Signed-off-by: David S.

Since the RFC series this includes a few extra changes to fix areas in the driver that either made this harder or were roadblocks due to deviations from the NCSI specification. Patches 1 & 2 fix two issues where the driver made assumptions about the capabilities of the NCSI topology. Patches 3 & 4 change some internal semantics slightly to make multi-mode easier. Patch 5 introduces a cleaner way of reconfiguring the NCSI configuration and keeping track of channel states. Patch 6 implements the main multi-package/multi-channel configuration, configured via the Netlink interface. Readers who have an interesting NCSI setup - especially multi-package with HWA - please test! I think I've covered all permutations but I don't have infinite hardware to test on. Changes in v2: - Updated use of the channel lock in ncsi_reset_dev(), making the channel invisible and leaving the monitor check to ncsi_stop_channel_monitor(). - Fixed ncsi_channel_is_tx() to consider the state of channels in other packages. Changes in v3: - Fixed bisectability bug in patch 1 - Consider channels on all packages in a few places when multi-package is enabled. - Avoid doubling up reset operations, and check the current driver state before reset to let any running operations complete. - Reorganise the LSC handler slightly to avoid enabling Tx twice. Changes in v4: - Fix failover in the single-channel case - Better handle ncsi_reset_dev() entry during a current config/suspend operation. ==================== Signed-off-by: David S.

NCSI_CMD_SET_PACKAGE mask and NCSI_CMD_SET_CHANNEL_MASK set a whitelist of packages or channels allowed to be configured with the NCSI_ATTR_PACKAGE_MASK and NCSI_ATTR_CHANNEL_MASK attributes respectively. If one of these whitelists is set only packages or channels matching the whitelist are considered for the channel queue in ncsi_choose_active_channel(). These commands may also use the NCSI_ATTR_MULTI_FLAG to signal that multiple packages or channels may be configured simultaneously. NCSI hardware arbitration (HWA) must be available in order to enable multi-package mode. Multi-channel mode is always available. If the NCSI_ATTR_CHANNEL_ID attribute is present in the NCSI_CMD_SET_CHANNEL_MASK command the it sets the preferred channel as with the NCSI_CMD_SET_INTERFACE command. The combination of preferred channel and channel whitelist defines a primary channel and the allowed failover channels. If the NCSI_ATTR_MULTI_FLAG attribute is also present then the preferred channel is configured for Tx/Rx and the other channels are enabled only for Rx.

However the channels are still configured and active from the perspective of the network controller. We should suspend each active channel but in the context of ncsi_stop_dev() the transmit queue has been or is about to be stopped so we won't have time to do so. Instead when ncsi_start_dev() is called if the NCSI topology has already been probed then call ncsi_reset_dev() to suspend any channels that were previously active. This resets the network controller to a known state, provides an up to date view of channel link state, and makes sure that mode flags such as NCSI_MODE_TX_ENABLE are properly reset. In addition to ncsi_start_dev() use ncsi_reset_dev() in ncsi-netlink.c to update the channel configuration more cleanly. Signed-off-by: Samuel Mendoza-Jonas Signed-off-by: David S.

Tweak this slightly so that NCSI_CHANNEL_ACTIVE represents a channel that has been configured and enabled, and NCSI_CHANNEL_INACTIVE represents a de-configured channel. This distinction is important because a channel can be 'active' but have its link down; in this case the channel may still need to be configured so that it may receive AEN link-state-change packets.

If the NCSI driver recognises that HWA is available it unconditionally enables all packages and channels; but that is a configuration decision rather than something required by HWA. Additionally the current implementation will not failover on link events which can cause connectivity to be lost unless the interface is manually bounced. Retain basic HWA support but remove the separate configuration path to enable all channels, leaving this to be handled by a later implementation.

The Qdisc matches nfp offload very well, but before we can offload it there are a number of improvements to make. First few patches add extack messages to the Qdisc and pass extack to netlink validation. Next a new netlink attribute group is added, to allow GRED to be extended more easily. Currently GRED passes C structures as attributes, and even an array of C structs for virtual queue configuration. User space has hard coded the expected length of that array, so adding new fields is not possible. New two-level attribute group is added: [TCA_GRED_VQ_LIST] [TCA_GRED_VQ_ENTRY] [TCA_GRED_VQ_DP] [TCA_GRED_VQ_FLAGS] [TCA_GRED_VQ_STAT_*] [TCA_GRED_VQ_ENTRY] [TCA_GRED_VQ_DP] [TCA_GRED_VQ_FLAGS] [TCA_GRED_VQ_STAT_*] [TCA_GRED_VQ_ENTRY] ... Statistics are dump only. Patch 4 switches the byte counts to be 64 bit, and patch 5 introduces the new stats attributes for dump. Patch 6 switches RED flags to be per-virtual queue, and patch 7 allows them to be dumped and set at virtual queue granularity. ==================== Signed-off-by: David S.

Validation of attributes is split from changes to make sure we won't have to undo previous operations when we find out configuration is invalid. The objective is to allow changing per-Qdisc parameters without overwriting the per-vq configured flags. Old user space will not pass the TCA_GRED_VQ_FLAGS attribute and per-Qdisc flags will always get propagated to the virtual queues. New user space which wants to make use of per-vq flags should set per-Qdisc flags to 0 and then configure per-vq flags as it sees fit. Once per-vq flags are set per-Qdisc flags can't be changed to non-zero. Vice versa - if the per-Qdisc flags are non-zero the TCA_GRED_VQ_FLAGS attribute has to either be omitted or set to the same value as per-Qdisc flags.

When this happens, the watchdog will be configured with a time in the past, fire straight way and the packet will finally be dropped once the dequeue() function of the qdisc is called again. We can save quite a few cycles and improve the overall behavior of the qdisc if we drop all expired packets if the next packet is expired. This should allow ETF to recover faster from bad situations. But packet drops are still a very serious warning that the requirements imposed on the system aren't reasonable.

The default hardware setup offers one queue of each type, as well as one DPCON channel, for each core available in the system. There are however cases where the number of queues is greater than the number of cores or channels. Until now, we configured and used all the frame queues associated with a DPNI, even if it meant assigning multiple queues of one type to the same channel. Update the driver to only use a number of queues equal to the number of channels, ensuring each channel will contain exactly one Rx and one Tx confirmation queue. >From the user viewpoint, this change is completely transparent. Performance wise there is no impact in most scenarios. In case the number of queues is larger than and not a multiple of the number of channels, Rx hash distribution offers now better load balancing between cores, which can have a positive impact on overall system performance.

At the same time __inet6_lookup expects dport to be in host byte order and correspondingly name the argument hnum. sk_lookup works correctly with __inet_lookup, __udp4_lib_lookup and __inet6_lookup with regard to dport. But in __udp6_lib_lookup case it uses host instead of expected network byte order. It makes result returned by bpf_sk_lookup_udp for IPv6 incorrect. The patch fixes byte order of dport passed to __udp6_lib_lookup. Originally sk_lookup properly handled UDPv6, but not TCPv6. 5ef0ae84f02a fixes TCPv6 but breaks UDPv6.

The PHY supports a number of different protocols, including PCIe and USB. The PHY lanes may be configured as single or multi-lane links. Each link is treated as a separate sub-node. For example, if there are 4 lanes in total the first 2 might be configured as a multi-lane PCIe link while the other two are single lane USB links, and in this case there would be 3 sub-nodes. There are two resets for the PHY block (one for APB register access, one for the PHY link) and separate resets for each link. For multi-lane links, the reset corresponds to the reset line on the master lane, the resets on other lanes have no effect.

It is caused by a circular dependency between the gpio and pinctrl frameworks. If the gpio-ranges property is present in device tree, then the gpio framework will handle the gpio pin registration and eliminate the circular dependency. See Christian Lamparter's commit a86caa9ba5d7 ("pinctrl: msm: fix gpio-hog related boot issues") for a detailed commit message that explains the issue in much more detail. The code comment in this commit came from Christian's commit. I did not test this change against any hardware supported by this particular driver, however I was able to validate this same fix works for pinctrl-spmi-gpio.c using a LG Nexus 5 (hammerhead) phone.

If I nudge the latency value written to the WM3 register just by one in either direction the problem disappears. That to me suggests that the punit will not enter the corrsponding powersave mode (MPLL shutdown IIRC) unless the latency value in the register matches exactly what we read from SSKPD. Ie. it's not really a latency value but rather just a cookie by which the punit can identify the desired power saving state. On HSW/BDW this was changed such that we actually just write the WM level number into those bits, which makes much more sense given the observed behaviour. We could try to handle this by disallowing LP3 watermarks only when vblank interrupts are enabled but we'd first have to prove that only vblank interrupts are affected, which seems unlikely. Also we can't grab the wm mutex from the vblank enable/disable hooks because those are called with various spinlocks held. Thus we'd have to redesigne the watermark locking. So to play it safe and keep the code simple we simply disable LP3 watermarks on all SNB machines. To do that we simply zero out the latency values for watermark level 3, and we adjust the watermark computation to check for that. The behaviour now matches that of the g4x/vlv/skl wm code in the presence of a zeroed latency value. v2: s/USHRT_MAX/U32_MAX/ for consistency with the types (Chris) Cc: stable@vger.kernel.org Cc: Chris Wilson Acked-by: Chris Wilson Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=101269 Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=103713 Signed-off-by: Ville Syrjälä Link: https://patchwork.freedesktop.org/patch/msgid/20181114173440.6730-1-ville.syrjala@linux.intel.com commit fa1c071c1efb28baef2409e28c186d40c76d7839 Author: Qiuxu Zhuo Date: Fri Nov 16 15:35:05 2018 +0800 EDAC, skx: Let EDAC core show the decoded result for debugfs Current debugfs shows the decoded result in its own print format which is inconvenient for analysis/statistics.

So the initially configured state should be retained. For the free case the PWM consumer is responsible for disabling the PWM before calling pwm_put() and there are three subcases to consider: a) The PWM is already off. Then there is no gain in disabling the PWM once more. b) The PWM is still running and there is a good reason for that. (Not sure this is a valid case, I cannot imagine such a good reason.) Then it is counterproductive to disable the PWM. c) The PWM is still running because the consumer failed to disable the PWM. Then the consumer needs fixing and there is little incentive to paper over the problem in the backend driver. This aligns the lpc18xx-sct driver to the other PWM drivers that also don't reconfigure the hardware in .request and .free.

To make it easy by keeping a script and which will generate the uapi header and syscall table file. This change will also help to unify the implemen- tation across all architectures. The system call table generation script is added in kernel/syscalls directory which contain the scripts to generate both uapi header file and system call table files. The syscall.tbl will be input for the scripts. syscall.tbl contains the list of available system calls along with system call number and corresponding entry point. Add a new system call in this architecture will be possible by adding new entry in the syscall.tbl file. Adding a new table entry consisting of: - System call number. - ABI. - System call name. - Entry point name. syscallhdr.sh and syscalltbl.sh will generate uapi header unistd_32.h and syscall_table.h files respectively. Both .sh files will parse the content syscall.tbl to generate the header and table files. unistd_32.h will be included by uapi/asm/unistd.h and syscall_table.h is included by kernel/syscall_table.S - the real system call table. ARM, s390 and x86 architecuture does have similar support. I leverage their implementation to come up with a generic solution.

We have to change the value of __NR_syscalls, if we add or delete a system call. One of the patch in this patch series has a script which will generate a uapi header based on syscall.tbl file. The syscall.tbl file contains the total number of system calls information. So we have two option to update __NR- _syscalls value. 1. Update __NR_syscalls in asm/unistd.h manually by count- ing the no.of system calls. No need to update NR_sys- calls until we either add a new system call or delete existing system call. 2. We can keep this feature it above mentioned script, that will count the number of syscalls and keep it in a generated file. In this case we don't need to expli- citly update __NR_syscalls in asm/unistd.h file. The 2nd option will be the recommended one. For that, I moved the __NR_syscalls macro from asm/unistd.h to uapi- /asm/unistd.h. While __NR_syscalls isn't strictly part of the uapi, having it as part of the generated header to simplifies the implementation. We also need to enclose this macro with #ifdef __KERNEL__ to avoid side effects.

The shuffling has a rather high latency, so the arithmetic units are not optimally used. Given that we have plenty of registers in AVX, this version parallelizes the 2-block variant to do four blocks. While the first two blocks are shuffling, the CPU can do the XORing on the second two blocks and vice-versa, which makes this version much faster than the SSSE3 variant for four blocks. The latter is now mostly for systems that do not have AVX2, but there it is the work-horse, so we keep it in place. The partial XORing function trailer is very similar to the AVX2 2-block variant. While it could be shared, that code segment is rather short; profiling is also easier with the trailer integrated, so we keep it per function.

Given that the setup code is rather cheap, the function does not process more than one block; this allows us to keep the block function selection in the C glue code. The required branching does not negatively affect performance for full block sizes. The partial XORing uses simple "rep movsb" to copy the data before and after doing XOR in SSE. This is rather efficient on modern processors; movsw can be slightly faster, but the additional complexity is probably not worth it.

In order to accommodate more masks than number of ERPs, the hardware supports to insert rules with delta bits. By that, the rules with masks that differ in up-to 8 consecutive bits can share the same ERP. Patches 1 and 2 fix couple of issues that would appear in existing selftests after adding delta support Patch 3 introduces a generic object aggregation library. Now it is static, but it will get extended for recalculation of aggregations in the future in order to reach more optimal aggregation. Patch 4 just simply converts existing ERP code to use the objagg library instead of a rhashtable. Patches 5-9 do more or less small changes to prepare ground for the last patch. Patch 10 fills-up delta callbacks of objagg library and utilizes the delta bits for rule insertion.

Benefit from the newly introduced objagg library and use it to track ERPs. At this point, there is no nesting of objects done, as the delta_create callback always returns -EOPNOTSUPP. On the way, add "mask" into ERP mask get and set functions and struct names. Signed-off-by: Jiri Pirko Signed-off-by: Ido Schimmel Signed-off-by: David S.

We can re-use this method in zfcp_fsf_req_complete(). Introduce a helper function to make the check for req->qtcb less magic. SRBs always are FSF_QTCB_UNSOLICITED_STATUS, so we can hard-code this for the two trace functions dealing with SRBs. All other FSF request types have a QTCB and we can get the fsf_command from there. zfcp_dbf_hba_fsf_response() and thus zfcp_dbf_hba_fsf_res() are only called for non-SRB requests so it's safe to dereference the QTCB [zfcp_fsf_req_complete() returns early on SRB, else calls zfcp_fsf_protstatus_eval() which calls zfcp_dbf_hba_fsf_response()]. In zfcp_scsi_forget_cmnd() we guard the QTCB dereference with a preceding NULL check and rely on boolean shortcut evaluation. As a side effect, this causes an alignment hole which we can close in a later patch after having cleaned up all fields of struct zfcp_fsf_req.

This regulator supports passing platform data, but enable/sleep regulators are looked up from the device tree exclusively, so we can need not touch other files. Tested on Odroid XU3 (with s2mps11 although not using any GPIOs for regulators, so at least default paths are not broken).

So it can be dropped. However, after reviewing some logs in libsas, it is noticed that debug level is too low in many instances. So this change drops SAS_DPRINTK() and revises some logs to a more appropriate level. However many stay at debug level, although some are significantly promoted. We add -DDEBUG for compilation so that we keep the debug messages by default, as before. All the pre-existing checkpatch errors for spanning messages across multiple lines are also fixed. Finally, all other references to printk() [apart from special formatting in sas_ata.c] are removed and replaced with appropriate pr_xxx().

These suffer from the same problem, the Marvell OUI, but no model number. As a result, these SERDES interfaces were getting the same PHY ID as the mv88e6390, even though they are not PHYs, and the Marvell PHY driver was trying to drive them.

Brett cleans up debug print messages by removing useless or duplicate messages, and make sure we assign the hardware head pointer to head instead of the software head pointer. Resolved an issue when disabling SRIOV we were trying to stop queues multiple times, so make sure we disable SRIOV before stopping transmit and receive queues for VF. Tony fixes a potential NULL pointer dereference during a VF reset. Anirudh resolves an issue where we were releasing the VSI before removing the VSI scheduler node, which was resulting in an error "Failed to set LAN Tx queue context, error: -1". Also fixed the guaranteed number of VSIs available and used by discovering the device capabilities to determine the 'guar_num_vsi' per function, rather than always using the theoretical max number of VSIs every time. Dave avoids a deadlock by nesting RTNL locking, so added a boolean to determine if the RTNL lock is already held. Lev fixes bad mask values which would break compilation. Piotr increases the receive queue disable timeout since it can take additional time to finish all pending queue requests. Usha resolves an issue of VLAN priority tagged traffic not appearing on all traffic classes, which was causing ETS bandwidth shaping to not work as expected. Henry fixes the reset path to cleanup the old scheduler tree before rebuilding it. Md Fahad removes a unnecessary check which was causing a driver load error on platforms with more than 128 cores. ==================== Signed-off-by: David S.

Rozycki Date: Tue Nov 13 22:42:44 2018 +0000 MIPS: SiByte: Enable swiotlb for SWARM, LittleSur and BigSur The Broadcom SiByte BCM1250, BCM1125, and BCM1125H SOCs have an onchip DRAM controller that supports memory amounts of up to 16GiB, and due to how the address decoder has been wired in the SOC any memory beyond 1GiB is actually mapped starting from 4GiB physical up, that is beyond the 32-bit addressable limit[1]. Consequently if the maximum amount of memory has been installed, then it will span up to 19GiB. Many of the evaluation boards we support that are based on one of these SOCs have their memory soldered and the amount present fits in the 32-bit address range. The BCM91250A SWARM board however has actual DIMM slots and accepts, depending on the peripherals revision of the SOC, up to 4GiB or 8GiB of memory in commercially available JEDEC modules[2]. I believe this is also the case with the BCM91250C2 LittleSur board. This means that up to either 3GiB or 7GiB of memory requires 64-bit addressing to access. I believe the BCM91480B BigSur board, which has the BCM1480 SOC instead, accepts at least as much memory, although I have no documentation or actual hardware available to verify that. Both systems have PCI slots installed for use by any PCI option boards, including ones that only support 32-bit addressing (additionally the 32-bit PCI host bridge of the BCM1250, BCM1125, and BCM1125H SOCs limits addressing to 32-bits), and there is no IOMMU available. Therefore for PCI DMA to work in the presence of memory beyond enable swiotlb for the affected systems. All the other SOC onchip DMA devices use 40-bit addressing and therefore can address the whole memory, so only enable swiotlb if PCI support and support for DMA beyond 4GiB have been both enabled in the configuration of the kernel. This shows up as follows: Broadcom SiByte BCM1250 B2 @ 800 MHz (SB1 rev 2) Board type: SiByte BCM91250A (SWARM) Determined physical RAM map: memory: 000000000fe7fe00 @ 0000000000000000 (usable) memory: 000000001ffffe00 @ 0000000080000000 (usable) memory: 000000000ffffe00 @ 00000000c0000000 (usable) memory: 0000000087fffe00 @ 0000000100000000 (usable) software IO TLB: mapped [mem 0xcbffc000-0xcfffc000] (64MB) in the bootstrap log and removes failures like these: defxx 0000:02:00.0: dma_direct_map_page: overflow 0x0000000185bc6080+4608 of device mask ffffffff bus mask 0 fddi0: Receive buffer allocation failed fddi0: Adapter open failed!

Rozycki Date: Tue Nov 13 22:42:30 2018 +0000 MIPS: SiByte: Set 32-bit bus mask for BCM1250 PCI The Broadcom SiByte BCM1250, BCM1125H and BCM1125 SOCs have an onchip 32-bit PCI host bridge, and the two former SOCs also have an onchip HT host bridge. The HT host bridge, where present, appears in the PCI configuration space as if it was a device on the 32-bit PCI bus behind the PCI host bridge, however at the hardware level its signals are routed separately, so these two devices are actually peer host bridges. As documented[1] and observed in reality the 32-bit PCI host bridge does not support 64-bit addressing as it does not support the Dual Address Cycle (DAC) PCI command, and naturally, being 32-bit only, it has no means to carry the high 32 address bits otherwise. However the DRAM controller also included in the SOC supports memory amounts of up to 16GiB, and due to how the address decoder has been wired in the SOC any memory beyond 1GiB is actually mapped starting from 4GiB physical up, that is beyond the 32-bit addressable limit. Consequently if the maximum amount of memory has been installed, then it will span up to 19GiB. Contrariwise, the HT host bridge does support full 40-bit addressing defined by the HyperTransport (formerly LDT) specification the bridge adheres to, depending on the peripherals revision of the SOC[2] either revision 0.17[3] or revision 1.03[4]. This allows addressing any and all memory installed, and well beyond. Set the bus mask then to limit DMA addressing to 32 bits for all the devices down the 32-bit PCI host bridge, excluding however any devices that are down the HT host bridge.

When not providing an appropriate delay after the STOP condition the i2c bus would get stuck. Also, any other traffic on the bus while talking to the monitor may cause the transaction to fail or even cause issues with the i2c bus as well. I2c-gates seemed to reach consent as a possible way to address these issues, and as such this patch is implementing a solution based on that. Since others are clearly relying on the current implementation of the driver, this patch won't require any DT changes. Since we don't want any interference during the DDC Bus Request/Grant procedure and while talking to the monitor, we have to use the adapter locking primitives rather than the i2c-mux locking primitives.

With this approach we will get different .config files depending on the order of the config fragment files. So doing something like: $ ./merge/kconfig/merge_config.sh selftest.config drm.config Where selftest.config defines DRM=y and drm.config defines DRM=m, the result will be "DRM=m". Rework to add a switch to get builtin '=y' precedence over modules '=m', this will result in "DRM=y".

We need to augment the bindings for proper DRM integration: the timings are expressed by the hardware, not put into the device tree. I.e. this hardware is self-describing and can report the resolutions and timings needed. It should not be described in the device tree. Further the device was incorrectly modeled with GPIO lines instead of an SPI child, even though the device was using SPI. No known deployments of the device using device tree exist, so it should be fine to augment the bindings.

We held and array of marking thresholds and statistics sized to the number of PF queues. This was sufficient since the only configuration we supported was single layer of RED Qdiscs (on top of MQ or not, but MQ isn't really about queuing). As we move to add more Qdiscs it's time to actually try to track the full Qdisc hierarchy. This allows us to make sure our offloaded configuration reflects the SW path better. We add graft notifications to MQ and RED (PRIO already sends them) to allow drivers offloading those to learn how Qdiscs are linked. MQ graft gives us the obvious advantage of being able to track when Qdiscs are shared or moved. It seems unlikely HW would offload RED's child Qdiscs but since the behaviour would change based on linked child we should stop offloading REDs with modified child. RED will also handle the child differently during reconfig when limit parameter is set - so we have to inform the drivers about the limit, and have them reset the child state when appropriate. The NFP driver will now allocate a structure to track each Qdisc and link it to its children. We will also maintain a shadow copy of threshold settings - to save device writes and make it easier to apply defaults when config is re-evaluated. ==================== Signed-off-by: David S.

The third BCD value is typically set to 0, but it looks that handling of it is broken in the hardware. It sometimes defaults to a random (even non-BCD) value. This is not an issue for handling RTCYEAR register, because bcd2bin() properly handles only 8bit values (2 BCD characters, the third one is skipped). The problem is however with ALMYEAR register and proper RTC alarm operation. When YEAREN bit is set for the configured alarm, RTC hardware triggers alarm only when ALMYEAR and RTCYEAR matches. This usually doesn't happen because of the random noise on the third BCD character. Fix this by simply skipping setting ALMYEAR register in alarm configuration. This workaround fixes broken alarm operation on Exynos built-in rtc device. My tests revealed that the issue happens on the following Exynos series: 3250, 4210, 4412, 5250 and 5410.

Most of the time, they are benign sensor readings. In any case, the top-level cros_ec device doesn't know enough to determine that they should wake the system, and so it should not report the event. This would be the job of the cros_ec_sensors driver to parse. This patch adds checks to cros_ec_get_next_event() such that it doesn't signal 'wakeup' for events of type EC_MKBP_EVENT_SENSOR_FIFO. This patch is particularly relevant on devices like Scarlet (Rockchip RK3399 tablet, known as Acer Chromebook Tab 10), where the EC firmware reports sensor events much more frequently. This was causing /sys/power/wakeup_count to increase very frequently, often needlessly interrupting our ability to suspend the system.

It currently returns negative for some errors, and non-negative (number of bytes received) for success (including some "no data available" responses as zero). This mostly works out OK, because the callers were more or less ignoring the documentation, and only treating positive values as success (and indepdently checking the modification of 'wakeup'). Let's button this up by avoiding pretending to handle event/wakeup distinctions when no event info was retrieved (i.e., returned 0 bytes). And fix the documentation of cros_ec_get_host_event() and cros_ec_get_next_event() to accurately describe their behavior.

But cpts rx/tx timestamp enable flags are used to allow ts retrieve only for one user. This limitation causes data path redundancy and setting overlap if cpsw module is in dual-mac mode for instance. If rx ts is enabled only for one port - the second interface must expect every incoming packet to be PTP packet w/o absolutely any reason, and if it's PTP - do unneeded stuff, as rx filter for second port is not set and cpts fifo is not supposed to contain appropriate ts event. That's not correct. So, to fix control overlap and avoid redundant CPU cycles, the patch splits rx/tx ts enable flags between network devices. After the patch, PTP timestamping still should be used for only one port (or PTP id counter has to be different for both ports as cpts IP is common).

However the code for setting USB path worked only for USB host mode (when ID pin is set to ground). When standard USB cable (USB device mode) is connected, path registers are not touched. This means that once the non-USB accessory is connected to MAX8997-operated micro USB port, the path is no longer set to USB and USB device mode doesn't work.

Sigh. The OLPC 1.75 boot firmware leaves two bytes in the TXFIFO. Those are basically throwaway bytes used in response to the messages from the EC. The OLPC kernel copes with this by power-cycling the hardware. Perhaps the firmware should do this instead. Other than that, there's not much we can do other than complain loudly until the garbage gets drained and discard the actual data... For the OLPC EC this will work just fine and pushing more data to TXFIFO would break further transactions.

Flags that may have been included within the event mask, but have not been explicitly requested by the user will not be present in the returned value. As an example, given the situation where a user requests events of type FAN_OPEN. Traditionally, the event mask returned within an event that occurred on a filesystem object that has been marked for monitoring and is opened, will only ever have the FAN_OPEN bit set. With the introduction of the new flags like FAN_OPEN_EXEC, and perhaps any other future event flags, there is a possibility of the returned event mask containing more than a single bit set, despite having only requested the single event type. Prior to these modifications performed to fanotify_should_send_event(), a user would have received a bundled event mask containing flags FAN_OPEN and FAN_OPEN_EXEC in the instance that a file was opened for execution via execve(), for example. This means that a user would receive event types in the returned event mask that have not been requested. This runs the possibility of breaking existing systems and causing other unforeseen issues. To mitigate this possibility, fanotify_should_send_event() has been modified to return the event mask containing ONLY event types explicitly requested by the user. This means that we will NOT report events that the user did no set a mask for, and we will NOT report events that the user has set an ignore mask for. The function name fanotify_should_send_event() has also been updated so that it's more relevant to what it has been designed to do.

This is incorrect and could have unintended consequences. To fix this use the valid_function's 8-bit bitmap returned from discovering device capabilities to determine the guar_num_vsi per function. guar_num_vsi value is then passed on to pf->num_alloc_vsi.

If not, the node is left in the scheduler tree and, on subsequent load, the scheduler tree contains the node so it does not set it in vsi_ctx. This, later, causes the node to not be found in ice_sched_get_free_qparent which leads to a "Failed to set LAN Tx queue context, error: -1". To remove the scheduler node, this patch introduces ice_rm_vsi_lan_cfg and related helpers.

To make it easy by keeping a script and which will generate the uapi header and syscall table file. This change will also help to unify the implemen- tation across all architectures. The system call table generation script is added in kernel/syscalls directory which contain the scripts to generate both uapi header file and system call table files. The syscall.tbl will be input for the scripts. syscall.tbl contains the list of available system calls along with system call number and corresponding entry point. Add a new system call in this architecture will be possible by adding new entry in the syscall.tbl file. Adding a new table entry consisting of: - System call number. - ABI. - System call name. - Entry point name. syscallhdr.sh and syscalltbl.sh will generate uapi header unistd_64.h and syscall_table.h files respectively. Both .sh files will parse the content syscall.tbl to generate the header and table files. unistd_64.h will be included by uapi/asm/unistd.h and syscall_table.h is included by kernel/entry.S - the real system call table. ARM, s390 and x86 architecuture does have similar support. I leverage their implementation to come up with a generic solution.

But most of the other architecute starts with 0. In order to come up with a common implementation to generate uapi header we need to add an offset - __NR_Linux with a value 1024. One of the patch in this patch series does have a script to generate uapi header which uses syscall.tbl file. In syscall- .tbl contain system call number. With the use of __NR_Linux, we can start the number from 0 instead of 1024.

We have to change the value of NR- _syscalls, if we add or delete a system call. One of the patch in this patch series has a script which will generate a uapi header based on syscall.tbl file. The syscall.tbl file contains the total number of system calls information. So we have two option to update NR_sy- scalls value. 1. Update NR_syscalls in asm/unistd.h manually by count- ing the no.of system calls. No need to update NR_sys- calls until we either add a new system call or delete existing system call. 2. We can keep this feature it above mentioned script, that will count the number of syscalls and keep it in a generated file. In this case we don't need to expli- citly update NR_syscalls in asm/unistd.h file. The 2nd option will be the recommended one. For that, I added the __NR_syscalls macro in uapi/asm/unistd.h along with NR_syscalls asm/unistd.h. The macro __NR_syscalls also added for making the name convention same across all architecture. While __NR_syscalls isn't strictly part of the uapi, having it as part of the generated header to simplifies the implementation. We also need to enclose this macro with #ifdef __KERNEL__ to avoid side effects.

The first is in the MIPI config block, but that apparenly usually (maybe always?) indicates 0 degrees despite the actual panel orientation. The second way to indicate this is in the general features block, which can just indicate whether 180 degress rotation is used. The third might be a separate rotation data block, but that is not at all documented so who knows what it may contain. Let's try the first two. We first try the DSI specicic VBT information, and it it doesn't look trustworthy (ie. indicates 0 degrees) we fall back to the 180 degree thing. Just to avoid too many changes in one go we shall also keep the hardware readout path for now. If this works for more than just my VLV FFRD the question becomes how many of the panel orientation quirks are now redundant? v2: Move the code into intel_dsi.c (Jani) Cc: Hans de Goede Reviewed-by: Jani Nikula Signed-off-by: Ville Syrjälä Link: https://patchwork.freedesktop.org/patch/msgid/20181022142015.4026-1-ville.syrjala@linux.intel.com Tested-by: Hans de Goede commit 86ef615fa11b57ac44ee895136f05712ea905a39 Author: Ville Syrjälä Date: Mon Oct 22 17:19:53 2018 +0300 drm/i915: Fix the VLV/CHV DSI panel orientation hw readout Let's make sure the DSI port is actually on before we go poking at the plane register to determine which way it's rotated.

In this case, the GXBB & GXL cannot work on more than 2000x2000 buffer, thus needing the OSD layer to be kept at 1920x1080 and upscaled to 3840x2160 in hardware.

The z-order is fixed and always behind the primary plane and cannot be changed.

The latter only works if a platform has an cpu-feature-overrides.h header which defines cpu_has_mips* macros, which are not generally needed. There are many cases where we know that the target ISA for a kernel build is MIPS32r1 or later & thus includes the CLZ instruction, without requiring any overrides from the platform. Using Kconfig allows us to take those into account, and more naturally make a decision about instruction support using information about the target ISA.

Since each QP can have up to two concurrent unrelated page-faults, one for requester and one for responder, page-fault handling can be done in parallel. Achieve this by changing the workqueue to be multi-threaded. The number of threads is the same as the number of command interface channels to avoid command interface bottlenecks. In addition to multi-threads, change the workqueue flags to give it high priority. Stress benchmark shows that before this change 85% of page faults were waiting in queue 8 seconds or more while after the change 98% of page faults were waiting in queue 64 milliseconds or less. The number of threads was chosen as the number of channels to the command interface.

The below is when 5 sockets are listening on 172.16.254.254:6400 on a server, 26 sockets on a client connect to 172.16.254.254:6400 and each may be processed by a different socket on the server which is selected by hash(lport, pport, paddr) in reuseport_select_sock(): # ss --sctp -nn State Recv-Q Send-Q Local Address:Port Peer Address:Port LISTEN 0 10 172.16.254.254:6400 *:* `- ESTAB 0 0 172.16.254.254%eth1:6400 172.16.2.1:1234 `- ESTAB 0 0 172.16.254.254%eth1:6400 172.16.2.4:1234 `- ESTAB 0 0 172.16.254.254%eth1:6400 172.16.3.3:1234 `- ESTAB 0 0 172.16.254.254%eth1:6400 172.16.3.4:1234 `- ESTAB 0 0 172.16.254.254%eth1:6400 172.16.5.2:1234 `- ESTAB 0 0 172.16.254.254%eth1:6400 172.16.5.3:1234 LISTEN 0 10 172.16.254.254:6400 *:* `- ESTAB 0 0 172.16.254.254%eth1:6400 172.16.1.3:1234 `- ESTAB 0 0 172.16.254.254%eth1:6400 172.16.1.4:1234 `- ESTAB 0 0 172.16.254.254%eth1:6400 172.16.3.2:1234 `- ESTAB 0 0 172.16.254.254%eth1:6400 172.16.4.1:1234 `- ESTAB 0 0 172.16.254.254%eth1:6400 172.16.4.2:1234 `- ESTAB 0 0 172.16.254.254%eth1:6400 172.16.4.3:1234 `- ESTAB 0 0 172.16.254.254%eth1:6400 172.16.4.4:1234 LISTEN 0 10 172.16.254.254:6400 *:* `- ESTAB 0 0 172.16.254.254%eth1:6400 172.16.1.2:1234 `- ESTAB 0 0 172.16.254.254%eth1:6400 172.16.3.5:1234 `- ESTAB 0 0 172.16.254.254%eth1:6400 172.16.4.5:1234 `- ESTAB 0 0 172.16.254.254%eth1:6400 172.16.253.253:1234 LISTEN 0 10 172.16.254.254:6400 *:* `- ESTAB 0 0 172.16.254.254%eth1:6400 172.16.2.2:1234 `- ESTAB 0 0 172.16.254.254%eth1:6400 172.16.2.3:1234 `- ESTAB 0 0 172.16.254.254%eth1:6400 172.16.5.4:1234 `- ESTAB 0 0 172.16.254.254%eth1:6400 172.16.5.5:1234 LISTEN 0 10 172.16.254.254:6400 *:* `- ESTAB 0 0 172.16.254.254%eth1:6400 172.16.1.1:1234 `- ESTAB 0 0 172.16.254.254%eth1:6400 172.16.1.5:1234 `- ESTAB 0 0 172.16.254.254%eth1:6400 172.16.2.5:1234 `- ESTAB 0 0 172.16.254.254%eth1:6400 172.16.3.1:1234 `- ESTAB 0 0 172.16.254.254%eth1:6400 172.16.5.1:1234 ==================== Signed-off-by: David S.

Therefore, kernel build arguments notwithstanding, it would be good to future-proof the code. This commit therefore substitutes INT_MAX for INT_MIN in order to avoid undefined behavior. While in the neighborhood, this commit also creates some meaningful names for INT_MAX and friends in order to improve readability, as suggested by Joel Fernandes.

McKenney Date: Tue Oct 16 04:12:58 2018 -0700 rcu: Speed up expedited GPs when interrupting RCU reader In PREEMPT kernels, an expedited grace period might send an IPI to a CPU that is executing an RCU read-side critical section. In that case, it would be nice if the rcu_read_unlock() directly interacted with the RCU core code to immediately report the quiescent state. And this does happen in the case where the reader has been preempted. But it would also be a nice performance optimization if immediate reporting also happened in the preemption-free case. This commit therefore adds an ->exp_hint field to the task_struct structure's ->rcu_read_unlock_special field. The IPI handler sets this hint when it has interrupted an RCU read-side critical section, and this causes the outermost rcu_read_unlock() call to invoke rcu_read_unlock_special(), which, if preemption is enabled, reports the quiescent state immediately. If preemption is disabled, then the report is required to be deferred until preemption (or bottom halves or interrupts or whatever) is re-enabled. Because this is a hint, it does nothing for more complicated cases. For example, if the IPI interrupts an RCU reader, but interrupts are disabled across the rcu_read_unlock(), but another rcu_read_lock() is executed before interrupts are re-enabled, the hint will already have been cleared. If you do crazy things like this, reporting will be deferred until some later RCU_SOFTIRQ handler, context switch, cond_resched(), or similar. Reported-by: Joel Fernandes Signed-off-by: Paul E.

This might make intuitive sense, but it also makes for confusing event-trace output because the "end" trace displays not the old but instead the new grace-period number. This commit therefore traces the end of an old grace period just before that grace period officially ends. Reported-by: Aravinda Prasad Signed-off-by: Paul E.

This is currently done for RCU CPU stall warnings by rcu_check_gp_start_stall(), which checks to see if the start of a requested grace period has been delayed by an RCU CPU stall warning period. Because rcutorture will need to check for the time consumed by an RCU forward-progress delay, this commit promotes gpssdelay from a local variable to a formal parameter. It is not necessary to export rcu_check_gp_start_stall() because rcutorture will access it via a wrapper function. Signed-off-by: Paul E.

There was therefore some hope that this would allow dropping the restriction against holding scheduler spinlocks across an rcu_read_unlock() without disabling interrupts across the entire corresponding RCU read-side critical section. Unfortunately, the need to quickly provide a quiescent state to expedited grace periods sometimes requires a call to raise_softirq() during rcu_read_unlock() execution. Because raise_softirq() can sometimes acquire the scheduler spinlocks, the restriction must remain in effect. This commit therefore updates the RCU requirements documentation accordingly.

It is tricky to make this dereference reliable for hash table lookups only under RCU as mark can get detached from the connector and connector gets freed independently of the running lookup. Thus there is a possible use after free / NULL ptr dereference issue: CPU1 CPU2 untag_chunk() ... audit_tree_lookup() list_for_each_entry_rcu(p, list, hash) { list_del_rcu(&chunk->hash); fsnotify_destroy_mark(entry); fsnotify_put_mark(entry) chunk_to_key(p) if (!chunk->mark.connector) ... hlist_del_init_rcu(&mark->obj_list); if (hlist_empty(&conn->list)) { inode = fsnotify_detach_connector_from_object(conn); mark->connector = NULL; ... frees connector from workqueue chunk->mark.connector->obj This race is probably impossible to hit in practice as the race window on CPU1 is very narrow and CPU2 has a lot of code to execute. Still it's better to have this fixed. Since the inode the chunk is attached to is constant during chunk's lifetime it is easy to cache the key in the chunk itself and thus avoid these issues.

Thus fsnotify_find_mark() in tag_chunk() may find a mark that belongs to a chunk that is no longer valid one and will soon be destroyed. Tags added to such chunk will be simply lost. Fix the problem by making sure old mark is marked as going away (through fsnotify_detach_mark()) before dropping mark_mutex and thus in an atomic way wrt tag_chunk(). Note that this does not fix the problem completely as if tag_chunk() finds a mark that is going away, it fails with -ENOENT. But at least the failure is not silent and currently there's no way to search for another fsnotify mark attached to the inode. We'll fix this problem in later patch.

In most places it however also uses mark->group->mark_mutex (as we need to atomically replace attached marks) and this provides protection against mark detaching as well. So just remove protection with mark->lock from audit tree code and replace it with mark->group->mark_mutex protection in all the places. It simplifies the code and gets rid of some ugly catches like calling fsnotify_add_mark_locked() with mark->lock held (which cannot sleep only because we hold a reference to another mark attached to the same inode).

This means that the read/write is not atomic even when performed to a 16-bit-aligned address. This leads to problems with vhost: vhost uses __getuser() to read the vring's 16-bit avail.index field, and if it happens to observe a partial update of the index, wrong descriptors will be used which will lead to a breakdown of the virtio communication. A similar problem exists for __putuser() which is used to write to the vring's used.index field. The reason these functions use strb[t]/ldrb[t] is because strht/ldrht instructions did not exist until ARMv6T2/ARMv7. So we should be easily able to fix this on ARMv7. Also, since all ARMv6 processors also don't actually use the unprivileged instructions anymore for uaccess (since CONFIG_CPU_USE_DOMAINS is not used) we can easily fix them too.

Any access beyond the 64k+ limit will cause a segmentation fault. The gcc -fstack-check option generates code to probe the stack for large stack allocation to see if the stack is accessible. The newer gcc does that while updating the %rsp simultaneously. Older gcc's like gcc4 doesn't do that. As a result, an application compiled with an old gcc and the -fstack-check option may fail to start at all: $ cat test.c int main() { char tmp[1024*128]; printf("### ok\n"); return 0; } $ gcc -fstack-check -g -o test test.c $ ./test Segmentation fault The old binary was working in older kernels where expand_stack() was somehow called before the check. But it is not working in newer kernels. Besides, the 64k+ limit check is kind of crude and will not catch a lot of mistakes that userspace applications may be misbehaving anyway. I think the kernel isn't the right place for this kind of tests. We should leave it to userspace instrumentation tools to perform them. The 64k+ limit check is now removed to just let expand_stack() decide if a segmentation fault should happen, when the RLIMIT_STACK limit is exceeded, for example.

This infrastructure adds basic I3C support. Advanced features will be added afterwards. There are a few design choices that are worth mentioning because they impact the way I3C device drivers can interact with their devices: - all functions used to send I3C/I2C frames must be called in non-atomic context. Mainly done this way to ease implementation, but this is not set in stone, and if anyone needs async support, new functions can be added later on. - the bus element is a separate object, but it's tightly coupled with the master object. We thus have a 1:1 relationship between i3c_bus and i3c_master_controller objects, and if 2 master controllers are connected to the same bus and both exposed to the same Linux instance they will appear as two distinct busses, and devices on this bus will be exposed twice. - I2C backward compatibility has been designed to be transparent to I2C drivers and the I2C subsystem. The I3C master just registers an I2C adapter which creates a new I2C bus. I'd say that, from a representation PoV it's not ideal because what should appear as a single I3C bus exposing I3C and I2C devices here appears as 2 different buses connected to each other through the parenting (the I3C master is the parent of the I2C and I3C busses). On the other hand, I don't see a better solution if we want something that is not invasive. Missing features: - I3C HDR modes are not supported - no support for multi-master and the associated concepts (mastership handover, support for secondary masters, ...) - I2C devices can only be described using DT because this is the only use case I have. However, the framework can easily be extended with ACPI and board info support - I3C slave framework. This has been completely omitted, but shouldn't have a huge impact on the I3C framework because I3C slaves don't see the whole bus, it's only about handling master requests and generating IBIs. Some of the struct, constant and enum definitions could be shared, but most of the I3C slave framework logic will be different Signed-off-by: Boris Brezillon Reviewed-by: Arnd Bergmann Acked-by: Greg Kroah-Hartman commit 58fc419be2313f8831ec75ad95263f050b69f476 Author: Andreas Jaggi Date: Thu Nov 1 06:50:33 2018 +0100 netfilter: ctnetlink: always honor CTA_MARK_MASK Useful to only set a particular range of the conntrack mark while leaving existing parts of the value alone, e.g. when updating conntrack marks via netlink from userspace.

This patch makes these checks static for CONFIG_PCI=n case so that the compiler optimizes out. The access to flags are replaced with macros that are replaced with a static value for CONFIG_PCI=n. The macros look slightly ugly for avoiding compiler warnings wrt unused variables, and some additional default-case handlings for another compiler warnings, but the rest are very straightforward changes.

In other cases the pattern above is used to update local, and/or not concurrently accessed, variables.

In both cases we ensure the UTIL_AVG_UNCHANGED flag is set to keep consistency between enqueue and dequeue time while still being transparent to update_load_avg calls which will eventually reset the flag. Let's move the flag forcing within _task_util_est() itself so that we can simplify calling code by hiding that estimated utilization implementation detail into one of its internal functions. This will affect also the "public" API task_util_est() but we know that the flag will (eventually) impact just on the LSB of the estimated utilization, thus it's certainly acceptable.

McKenney Date: Tue Sep 11 08:57:48 2018 -0700 rcu: Stop expedited grace periods from relying on stop-machine The CPU-selection code in sync_rcu_exp_select_cpus() disables preemption to prevent the cpu_online_mask from changing. However, this relies on the stop-machine mechanism in the CPU-hotplug offline code, which is not desirable (it would be good to someday remove the stop-machine mechanism). This commit therefore instead uses the relevant leaf rcu_node structure's ->ffmask, which has a bit set for all CPUs that are fully functional. A given CPU's bit is cleared very early during offline processing by rcutree_offline_cpu() and set very late during online processing by rcutree_online_cpu(). Therefore, if a CPU's bit is set in this mask, and preemption is disabled, we have to be before the synchronize_sched() in the CPU-hotplug offline code, which means that the CPU is guaranteed to be workqueue-ready throughout the duration of the enclosing preempt_disable() region of code. This also has the side-effect of using WORK_CPU_UNBOUND if all the CPUs for this leaf rcu_node structure are offline, which is an acceptable difference in behavior.

However, when unused, these SERDES interfaces can be used by some of the lower ports for 1000Base-X. The tricky bit here is ordering. The SERDES have to become free from ports 9 or 10 before they can be used with lower ports. Normally, this would happen only when these ports would be configured up, which is too late. So at probe time, defaulting ports 9 and 10 to 1000BaseX frees them for use with lower ports. If they are actually needed, they will be taken back when port 9 and 10 goes up. ==================== Signed-off-by: David S.

This allows ports 9 and 10 to support up to 10Gbps using 4 SERDES interfaces. However, when lower speeds are used, which need fewer SERDES interfaces, the unused SERDES interfaces can be used by ports 2-8. The hardware defaults to ports 9 and 10 having all 4 SERDES interfaces assigned to them. This only gets changed when the interface is configured after what the SFP supports has been determined, or the 10G PHY completes auto-neg. For hardware designs which limit ports 9 and 10 to one or two SERDES interfaces, and place SFPs on the lower interfaces, this is too late. Those ports with SFP should not wait until ports 9/10 are up in order to get access to the SERDES interface. So change the default configuration when the driver is initialised. Configure ports 9 and 10 to 1000BaseX, so they use a single SERDES interface, freeing up the others. They can steal them back if they need them. Signed-off-by: Andrew Lunn Signed-off-by: David S.

This helps to restrict retransmission of individual broadcast packets to max once per 10 milliseconds, even though all other criteria for retransmission are met. We now move this time stamp to the control block of each individual packet, and remove other limiting criteria. This simplifies the retransmission algorithm, and eliminates any risk of logical errors in selecting which packets can be retransmitted.

Drivers can track new netdevs or register to existing ones to receive information on such events. Based on this, they may register for block offload rules using already existing functions. The patchset also implements this new indirect block registration in the NFP driver to allow the offloading of tunnel rules. The use of egdev offload (which is currently only used for tunnel offload) is subsequently removed. RFC v2 -> PATCH - removed embedded tracking function from indir block register (now up to driver to clean up after itself) - refactored NFP code due to recent submissions - removed priv list clean function in NFP (list should be cleared by indirect block unregisters) RFC v1->v2: - free allocated owner struct in block_owner_clean function - add geneve type helper function - move test stub in NFP (v1 patch 2) to full tunnel offload implementation via indirect blocks (v2 patches 3-8) ==================== Signed-off-by: David S.

This meant that the driver had no access to the ingress netdev and so could not verify it was the same tunnel type that the rule implied. Register tunnel devices for indirect TC block offloads in NFP, giving access to new rules based on the ingress device rather than egress. Use this to verify the netdev type of VXLAN and Geneve based rules and offload the rules to HW if applicable. Tunnel registration is done via a netdev notifier. On notifier registration, this is triggered for already existing netdevs. This means that NFP can register for offloads from devices that exist before it is loaded (filter rules will be replayed from the TC core). Similarly, on notifier unregister, a call is triggered for each currently active netdev. This allows the driver to unregister any indirect block callbacks that may still be active.

Introduce indirect block devs which allows drivers to register callbacks for block binds on other devices. The callback is triggered when the device is bound to a block, allowing the driver to register for rules applied to that block using already available functions. Freeing an indirect block callback will trigger an unbind event (if necessary) to direct the driver to remove any offloaded rules and unreg any block rule callbacks. It is the responsibility of the implementing driver to clean any registered indirect block callbacks before exiting, if the block it still active at such a time. Allow registering an indirect block dev callback for a device that is already bound to a block. In this case (if it is an ingress block), register and also trigger the callback meaning that any already installed rules can be replayed to the calling driver.

To get usable results from the temperature sensor we need to read the corresponding calibration data from the eFuse and pass it to the SAR ADC registers. If the temperature sensor is not calibrated (the eFuse data contains a bit for this) then the driver will only register the iio_chan_spec's for voltage measurements. This only enables the temperature sensor for the Meson8 SoC. Meson8b and Meson8m2 SoCs can be supported in the future as well but we first need a way to pass the fifth TSC (temperature sensor coefficient) bit to the HHI register area (apart from that the infrastructure as already implemented for Meson8 can be used). On the 64-bit SoCs (GXBB, GXL and GXM) the temperature sensor inside SAR ADC is firmware-controlled (by BL30, we can simply use the SCPI hwmon driver to get the chip temperature). To keep the devicetree interface backwards compatible we simply skip the temperature sensor initialization if no eFuse nvmem cell is passed via devicetree. The public documentation for the SAR ADC IP block does not explain how to use the registers to read the temperature. The logic from this patch is based on reading and understanding Amlogic's GPL kernel sources.

The first PERST is expected and indicates the device on coming resume flow. The second PERST causes FW restart FW restart. In order to avoid this issue, the FW set the persistence bit on. Once this bit is set, the FW ignores reset attempts. The problem is when the FW gets assert during D3 and then the persistence bit is set and causes the FW to ignore reset. To handle this issue, the FW opens the preg bit which allows access to the persistence bit, so that the driver clear the persistence bit and reset the NIC. The flow is as follows: the driver checks if the persistence bit is set. If the bit is set, the driver checks if he can clear the bit. If the driver can not clear the bit then there is no point to continue configuring the NIC since it will fail. The fix was added is in start HW flow instead of the resume flow since in general, if the persistence bit is set, the driver can not start the FW. So it is good to check it when we start configuring the NIC. The driver does not need to close the preg bit since the FW close it during the start flow.

E.g. if there is a __u32 field then only the following loads are permitted: * off=0, size=1 (narrow); * off=0, size=2 (narrow); * off=0, size=4 (full). On the other hand LLVM can generate a load with offset different than zero that make sense from program logic point of view, but verifier doesn't accept it. E.g. tools/testing/selftests/bpf/sendmsg4_prog.c has code: #define DST_IP4 0xC0A801FEU /* 192.168.1.254 */ ... if ((ctx->user_ip4 >> 24) == (bpf_htonl(DST_IP4) >> 24) && where ctx is struct bpf_sock_addr. Some versions of LLVM can produce the following byte code for it: 8: 71 12 07 00 00 00 00 00 r2 = *(u8 *)(r1 + 7) 9: 67 02 00 00 18 00 00 00 r2 <<= 24 10: 18 03 00 00 00 00 00 fe 00 00 00 00 00 00 00 00 r3 = 4261412864 ll 12: 5d 32 07 00 00 00 00 00 if r2 != r3 goto +7 where `*(u8 *)(r1 + 7)` means narrow load for ctx->user_ip4 with size=1 and offset=3 (7 - sizeof(ctx->user_family) = 3). This load is currently rejected by verifier. Verifier code that rejects such loads is in bpf_ctx_narrow_access_ok() what means any is_valid_access implementation, that uses the function, works this way, e.g. bpf_skb_is_valid_access() for __sk_buff or sock_addr_is_valid_access() for bpf_sock_addr. The patch makes such loads supported. Offset can be in [0; size_default) but has to be multiple of load size. E.g. for __u32 field the following loads are supported now: * off=0, size=1 (narrow); * off=1, size=1 (narrow); * off=2, size=1 (narrow); * off=3, size=1 (narrow); * off=0, size=2 (narrow); * off=2, size=2 (narrow); * off=0, size=4 (full).

Miller commit 4a5a553ddef76cbeb346414ddfd91aef8de07532 Author: David S. Miller Date: Sat Aug 11 21:14:34 2018 -0700 brcmfmac: Use standard SKB list accessors in brcmf_sdiod_sglist_rw. Instead of direct SKB list pointer accesses. The loops in this function had to be rewritten to accommodate this more easily. The first loop iterates now over the target list in the outer loop, and triggers an mmc data operation when the per-operation limits are hit. Then after the loops, if we have any residue, we trigger the last and final operation. For the page aligned workaround, where we have to copy the read data back into the original list of SKBs, we use a two-tiered loop. The outer loop stays the same and iterates over pktlist, and then we have an inner loop which uses skb_peek_next(). The break logic has been simplified because we know that the aggregate length of the SKBs in the source and destination lists are the same. This change also ends up fixing a bug, having to do with the maintainance of the seg_sz variable and how it drove the outermost loop. It begins as: seg_sz = target_list->qlen; ie. the number of packets in the target_list queue. The loop structure was then: while (seq_sz) { ... while (not at end of target_list) { ... sg_cnt++ ... } ... seg_sz -= sg_cnt; The assumption built into that last statement is that sg_cnt counts how many packets from target_list have been fully processed by the inner loop. But this not true. If we hit one of the limits, such as the max segment size or the max request size, we will break and copy a partial packet then contine back up to the top of the outermost loop. With the new loops we don't have this problem as we don't guard the loop exit with a packet count, but instead use the progression of the pkt_next SKB through the list to the end. The general structure is: sg_cnt = 0; skb_queue_walk(target_list, pkt_next) { pkt_offset = 0; ... sg_cnt++; ... while (pkt_offset < pkt_next->len) { pkt_offset += sg_data_size; if (queued up max per request) mmc_submit_one(); } } if (sg_cnt) mmc_submit_one(); The variables that maintain where we are in the MMC command state such as req_sz, sg_cnt, and sgl are reset when we emit one of these full sized requests.

Example: bpftool prog load tools/testing/selftests/bpf/bpf_flow.o \ /sys/fs/bpf/flow type flow_dissector \ pinmaps /sys/fs/bpf/flow bpftool map update pinned /sys/fs/bpf/flow/jmp_table \ key 0 0 0 0 \ value pinned /sys/fs/bpf/flow/IP bpftool map update pinned /sys/fs/bpf/flow/jmp_table \ key 1 0 0 0 \ value pinned /sys/fs/bpf/flow/IPV6 bpftool map update pinned /sys/fs/bpf/flow/jmp_table \ key 2 0 0 0 \ value pinned /sys/fs/bpf/flow/IPV6OP bpftool map update pinned /sys/fs/bpf/flow/jmp_table \ key 3 0 0 0 \ value pinned /sys/fs/bpf/flow/IPV6FR bpftool map update pinned /sys/fs/bpf/flow/jmp_table \ key 4 0 0 0 \ value pinned /sys/fs/bpf/flow/MPLS bpftool map update pinned /sys/fs/bpf/flow/jmp_table \ key 5 0 0 0 \ value pinned /sys/fs/bpf/flow/VLAN bpftool prog attach pinned /sys/fs/bpf/flow/flow_dissector flow_dissector Tested by using the above lines to load the prog in the test_flow_dissector.sh selftest.

The first two patches are minor cleanup/bug fixes. The third patch adds an extended version of the PTP_SYS_OFFSET ioctl, which returns three timestamps for each measurement. The idea is to shorten the interval between the system timestamps to contain just the reading of the lowest register of the PHC in order to reduce the error in the measured offset and get a smaller upper bound on the maximum error. The fourth patch deprecates the original gettime function. The remaining patches update the gettime function in order to support the new ioctl in the e1000e, igb, ixgbe, and tg3 drivers. Tests with few different NICs in different machines show that: - with an I219 (e1000e) the measured delay was reduced from 2500 to 1300 ns and the error in the measured offset, when compared to the cross timestamping supported by the driver, was reduced by a factor of 5 - with an I210 (igb) the delay was reduced from 5100 to 1700 ns - with an I350 (igb) the delay was reduced from 2300 to 750 ns - with an X550 (ixgbe) the delay was reduced from 1950 to 650 ns - with a BCM5720 (tg3) the delay was reduced from 2400 to 1200 ns ==================== Acked-by: Richard Cochran Signed-off-by: David S.

This typically involves reading of multiple PCI registers (sometimes in multiple iterations) and the register that contains the lowest bits of the timestamp is not read in the middle between the two readings of the system clock. This asymmetry causes the measured offset to have a significant error. Introduce a new ioctl, driver function, and helper functions, which allow the reading of the lowest register to be isolated from the other readings in order to reduce the asymmetry. The ioctl returns three timestamps for each measurement: - system time right before reading the lowest bits of the PHC timestamp - PHC time - system time immediately after reading the lowest bits of the PHC timestamp Cc: Richard Cochran Cc: Jacob Keller Cc: Marcelo Tosatti Signed-off-by: Miroslav Lichvar Signed-off-by: David S.

Unfortunately for unknown reasons this doesn't work well with some MIPS CPUs such as the P6600, particularly when using an I/O Coherence Unit (IOCU) to provide cache-coherent DMA. In these systems it is common for DMA data to be lost, resulting in broken access to EG20T devices such as the MMC or SATA controllers. Support for a DT property to configure the prefetching was added a while back by commit 549ce8f134bd ("misc: pch_phub: Read prefetch value from device tree if passed") but we never added the DT snippet to make use of it. Add that now in order to disable the prefetching & fix DMA on the affected systems.

VF reset: triggered by sending cmd to IMP(Integrated Management Processor). Only reset specific VF function and do not affect other PF or VF. 2. PF reset: triggered by sending cmd to IMP. Only reset specific PF and it's VF. 3. PF FLR: triggered by PCIe subsystem. Only reset specific PF and it's VF. 4. VF FLR: triggered by PCIe subsystem. Only reset specific VF function and do not affect other PF or VF. 5. Core reset: triggered by writing to register. Reset most hardware unit, such as SSU, which affects all the PF and VF. 6. Global reset: triggered by writing to register. Reset all hardware unit, which affects all the PF and VF. 7. IMP reset: triggered by IMU(Intelligent Management Unit) when IMP is not longer feeding IMU's watchdog. IMU will reload the IMP firmware and IMP will perform global reset after firmware reloading, which affects all the PF and VF. Current driver only support PF/VF reset, incomplete core and global reset(lacking the vf reset handling). So this patchset adds complete reset support in hns3 driver.

This patch implements the missing IMP reset handling in the driver. 1. The driver sets the HCLGE_STATE_CMD_DISABLE to stop sending command after receiving the IMP reset interrupt. 2. The driver needs to notify the hardware to reload the IMP firmware. 3. The IMP firmware reloading makes the reset time of hardware longer, so it is necessary to extend the driver's waiting time to wait for the hardware reset to complete. 4. In hclge_check_event_cause, IMP reset event should have higher priority than other events. Also, after clearing HCLGE_STATE_CMD_DISABLE in the hclge_cmd_init(), it needs to check whether there is a pending reset, if so, just set the HCLGE_STATE_CMD_DISABLE back and return.

Add member reset_pending to struct hclgevf_dev, which indicates that there is reset event need to be processed by the VF's reset task, and the VF's reset task chooses the highest-level one and clears other low-level one when it processes reset_pending. hclge_inform_reset_assert_to_vf function is unused now, but it will be used to support the PF reset with VF working, so declare it in the header file.

For example: .set push .set mips32r2 .set pop 2) Using .set mips0 to restore the ISA originally specified on the command line. For example: .set mips32r2 .set mips0 Unfortunately method 2 does not work with nanoMIPS toolchains, where the assembler rejects the .set mips0 directive like so: Error: cannot change ISA from nanoMIPS to mips0 In preparation for supporting nanoMIPS builds, switch all instances of method 2 in generic non-platform-specific code to use push & pop as in method 1 instead. The .set push & .set pop is arguably cleaner anyway, and if nothing else it's good to consistently use one method.

This results in a couple of inconsistencies: - ptrace will return the default initial state of FP registers rather than the values actually stored in struct thread_struct, hiding state that has been updated by emulated floating point instructions. - If a task migrates to a CPU with an FPU after having emulated floating point instructions then its floating point register state will be reset to the default ~0 bit pattern, losing state from the emulated instructions. Fix this by calling init_fp_ctx() from fpu_emulator_cop1Handler() to consistently initialize FP state if it was previously uninitialized, setting the PF_USED_MATH flag in the process. All callers of fpu_emulator_cop1Handler() either call lose_fpu(1) before it in order to save any live FPU registers to struct thread_struct, or in the case of do_cpu() already know that the task does not own an FPU so lose_fpu(1) would be a no-op. Since we know that saving FP context will be unnecessary in the case where FP context was just initialized we move this call into fpu_emulator_cop1Handler() too, providing consistency & avoiding needless duplication. Calls to own_fpu(1) are common after return from fpu_emulator_cop1Handler() too, but this would not be a no-op in the do_cpu() case so these are left as-is. A potential future improvement could be to have fpu_emulator_cop1Handler() restore FPU state automatically only if it saved it, though this may not be optimal if some callers are better off without their current calls to own_fpu(1). One potential example of this could be mipsr2_decoder() which as-is could end up saving & restoring FP context repeatedly & unnecessarily if emulating multiple FP instructions.

The _init_fpu() path has 2 separate implementations - one for r2k/r3k style systems & one for r4k style systems. The _init_fpu() path also requires that we be careful to clear & restore the value of the Config5.FRE bit on modern systems in order to avoid inadvertently triggering floating point exceptions. None of this code is in a performance critical hot path - it runs only the first time a task uses floating point. As such it doesn't seem to warrant the complications of maintaining the _init_fpu() path. Remove _init_fpu() & fpu_emulator_init_fpu(), instead using init_fp_ctx() consistently to initialize floating point register state in struct thread_info. Upon a task's first use of floating point this will typically mean that we initialize state in memory & then load it into FPU registers using _restore_fp() just as we would on a context switch. For other paths such as __compute_return_epc_for_insn() or mipsr2_decoder() this results in a significant simplification of the work to be done.

This means that they've already grabbed their port->lock spinlock. This can end up getting in the way if we've go to do serial stuff (especially kgdb) in response to the sysrq. Serial drivers have various hacks in them to handle this. Looking at '8250_port.c' you can see that the console_write() skips locking if we're in the sysrq handler. Looking at 'msm_serial.c' you can see that the port lock is dropped around uart_handle_sysrq_char(). It turns out that these hacks aren't exactly perfect. If you have lockdep turned on and use something like the 8250_port hack you'll get a splat that looks like: WARNING: possible circular locking dependency detected [...] is trying to acquire lock: ...

It seems like we could defer processing the sysrq until the end of the interrupt handler right after we've unlocked the port. With this scheme if a whole batch of sysrq characters comes in one irq then we won't handle them all, but that seems like it should be a fine compromise.

Let's make it useful by adding that define using the same formula found in other serial drivers. In order to prevent deadlock, we'll take a page from the 'msm_serial.c' where the spinlock is released around uart_handle_sysrq_char(). This seemed better than copying from '8250_port.c' where we skip locking in the console_write function since the '8250_port.c' method can cause lockdep warnings when dropping into kgdb.

We implement the workaround during encoder disable, but looks like some BIOSen leave transcoder B selected even when the port wasn't actually enabled by the BIOS. That will trip up our asserts that attempt to make sure we never forget this w/a. Sanitize the transcoder select to A for all disabled PCH DP/HDMI/SDVO ports. We assume that the port was never enabled by the BIOS on transcoder B, because if it had we'd actually have to toggle the port on and back off to properly switch it back to transcoder A. That would cause some display flicker if transcoder A is already enabled on some other port, so it's better not to do it unless absolutely necessary. Since we have no indication that the transcoder select is misbehaving on the affected machines we can assume the port was never actually enabled by the BIOS.

Previously we would only handle such pins via ->hpd_pulse(), but now we queue up the hotplug work for the HDMI encoder directly. Worse yet, we now count each hpd twice and this increment the hpd storm count twice as fast. This can lead to spurious storms being detected. Go back to the old way of doing things, ie. delegate to ->hpd_pulse() for any pin which has an encoder with that hook implemented. I don't really like the idea of adding irq_port[] back so let's loop through the encoders first to check if we have an encoder with ->hpd_pulse() for the pin, and then go through all the pins and decided on the correct course of action based on the earlier findings. I have occasionally toyed with the idea of unifying the pre-DDI HDMI and DP encoders into a single encoder as well. Besides the hotplug processing it would have the other benefit of preventing userspace from trying to enable both encoders at the same time. That is simply illegal as they share the same clock/data pins. We have some testcases that will attempt that and thus fail on many older machines. But for now let's stick to fixing just the hotplug code.

Also we should not sanitize the mapping for MST encoders, as it's always their primary encoder (which could be even in SST mode) whose active state determines if we need the clock being enabled for the corresponding physical port. Fix this too. This fixes at least an existing breakage where we incorrectly disabled the clock for an active DP encoder when sanitizing its MST virtual encoders. Not sure if there are BIOSes that enable an output in MST mode, but our HW readout is mostly missing for it anyway, so just warn for that case.

Inexact policies now end up in one of the following four search classes: 1. "Any:Any" list, containing policies where both saddr and daddr are wildcards or have very coarse prefixes, e.g. 10.0.0.0/8 and the like. 2. "saddr:any" list, containing policies with a fixed saddr/prefixlen, but without destination restrictions. These lists are stored in rbtree nodes; each node contains those policies matching saddr/prefixlen. 3. "Any:daddr" list. Similar to 2), except for policies where only the destinations are specified. 4. "saddr:daddr" lists, containing only those policies that match the given source/destination network. The root of the saddr/daddr nodes gets stored in the nodes of the 'daddr' tree. This diagram illustrates the list classes, and their placement in the lookup hierarchy: xfrm_pol_inexact_bin = hash(dir,type,family,if_id); | +---- root_d: sorted by daddr:prefix | | | xfrm_pol_inexact_node | | | +- root: sorted by saddr/prefix | | | | | xfrm_pol_inexact_node | | | | | + root: unused | | | | | + hhead: saddr:daddr policies | | | +- coarse policies and all any:daddr policies | +---- root_s: sorted by saddr:prefix | | | xfrm_pol_inexact_node | | | + root: unused | | | + hhead: saddr:any policies | +---- coarse policies and all any:any policies lookup for an inexact policy returns pointers to the four relevant list classes, after which each of the lists needs to be searched for the policy with the higher priority.

In this initial version, we now no longer need to search policies with non-matching address family and type. Next patch will add the if_id as well so lookups from the xfrm interface driver only need to search inexact policies for that device. Future patches will augment the hlist in each rhash bucket with a tree and pre-sort policies according to daddr/prefix. A single rhashtable is used. In order to avoid a full rhashtable walk on netns exit, the bins get placed on a pernet list, i.e. we add almost no cost for network namespaces that had no xfrm policies. The inexact lists are kept in place, and policies are added to both the per-rhash-inexact list and a pernet one. The latter is needed for the control plane to handle migrate -- these requests do not consider the if_id, so if we'd remove the inexact_list now we would have to search all hash buckets and then figure out which matching policy candidate is the most recent one -- this appears a bit harder than just keeping the 'old' inexact list for this purpose.

Searching this inexact list is slow, so it might be better to pre-sort inexact lists into a tree or another data structure for faster searching. However, due to 'any' policies, that need to be searched in any case, doing so will require that 'inexact' policies need to be handled specially to decide the best search strategy. So change hash_bysel() and return NULL if the policy can't be handled via the policy hash table. Right now, we simply use the inexact list when this happens, but future patch can then implement a different strategy. Signed-off-by: Florian Westphal Acked-by: David S.

Seeing as how apparently no one can get this right with the current approach, change all the reporting functions to: - Start by memsetting the report structure to 0. This guarantees it's always initialized, regardless of what happens later. - Initialize all strings using strscpy(). This is safe after the memset, ensures null termination of long strings, avoids unnecessary work, and avoids the -Wstringop-truncation warnings from gcc. - Use sizeof(var) instead of sizeof(type). This is more robust against copy+paste errors. For simplicity, also reuse the -EMSGSIZE return value from nla_put().

The meta data of the DMA pool, including the pool used for the allocation 'ndev->ctx_pool' and the base address of the DMA pool used by the device 'dma', are then stored to the beginning of the pool. These meta data are eventually used in crypto_free_context() to free the DMA pool through dma_pool_free(). However, given that the DMA pool can also be accessed by the device, a malicious device can modify these meta data, especially when the device is controlled to deploy an attack. This can cause an unexpected DMA pool free failure. To avoid the above issue, this patch introduces a new structure crypto_ctx_hdr and a new field chdr in the structure nitrox_crypto_ctx hold the meta data information of the DMA pool after the allocation. Note that the original structure ctx_hdr is not changed to ensure the compatibility.

This is feasible because due to ARM's "free" rotations, the main tables are only 1024 bytes instead of the usual 4096 used by most AES implementations. On ARM Cortex-A7, the speed loss is only about 5%. The resulting code is still over twice as fast as aes_ti.c. Responsiveness is potentially a concern, but interrupts are only disabled for a single AES block. Note that even after these changes, the implementation still isn't necessarily guaranteed to be constant-time; see https://cr.yp.to/antiforgery/cachetiming-20050414.pdf for a discussion of the many difficulties involved in writing truly constant-time AES software. But it's valuable to make such attacks more difficult. Much of this patch is based on patches suggested by Ard Biesheuvel.

Previously it was possible for the CPU to be interrupted while the S-box was loaded into L1 cache, potentially evicting the cachelines and causing later table lookups to be time-variant.

Our main use case for this is the following: We would like to monitor some subset of TCP sockets in user-space, (the monitoring application would define 4-tuples it wants to monitor) using TCP_INFO stats to analyze reported problems. The idea is to use those stats to see where the bottlenecks are likely to be ("is it application-limited?" or "is there evidence of BufferBloat in the path?" etc). Today we can do this by periodically polling for tcp_info, but this could be made more efficient if the kernel would asynchronously notify the application via tcp_info when some "interesting" thresholds (e.g., "RTT variance > X", or "total_retrans > Y" etc) are reached. And to make this effective, it is better if we could apply the threshold check *before* constructing the tcp_info netlink notification, so that we don't waste resources constructing notifications that will be discarded by the filter. This work solves the problem by adding perf event based notification support for sock_ops. The eBPF program can thus be designed to apply any desired filters to the bpf_sock_ops and trigger a perf event notification based on the evaluation from the filter. The user space component can use these perf event notifications to either read any state managed by the eBPF program, or issue a TCP_INFO netlink call if desired.

The node passed to __of_attach_node() when the add node changeset entry is processed does not contain any properties. The node's properties are located in add property changeset entries that will be processed after the add node changeset is applied. Set the node's fields in the node contained in the add node changeset entry and do not set them to incorrect values in add_changeset_node(). A visible symptom that is fixed by this patch is the names of nodes added by overlays that have an entry in /sys/bus/platform/drivers/*/ will contain the unit-address but the node-name will be , for example, "fc4ab000.". After applying the patch the name, in this example, for node restart@fc4ab000 is "fc4ab000.restart".

The decision of whether to use 'update property' was based on whether the property already exists in the subtree where the node is being spliced into. At the top level of creating a changeset describing the overlay, the target node is in the live devicetree, so checking whether the property exists in the target node returns the correct result. As soon as the changeset creation algorithm recurses into a new node, the target is no longer in the live devicetree, but is instead in the detached overlay tree, thus all properties are incorrectly found to already exist in the target. This fix will expose another devicetree bug that will be fixed in the following patch in the series.

This allows __call_srcu() to use SRCU read-side critical sections to prevent a new SRCU grace period from ending before the call to either srcu_funnel_gp_start() or srcu_funnel_exp_start completes, thus preventing SRCU grace-period counter overflow during that time. Note that this does not permit removal of the counter-wrap checks in srcu_gp_end(). These check are necessary to handle the case where a given CPU does not interact at all with SRCU for an extended time period. This commit therefore adds an SRCU read-side critical section to __call_srcu() in order to prevent grace period counter wrap during the funnel-locking process. Signed-off-by: Paul E.

McKenney Date: Thu Aug 23 10:48:18 2018 -0700 rcutorture: Add initrd support for systems lacking dracut The support for creating initrd directories using dracut is a great improvement over having to always hand-create them, it is a bit annoying to have to install some otherwise irrelevant package just to be able to run rcutorture. This commit therefore adds support for creating initrd directories on systems innocent of dracut. You do need gcc, but then again you need that to build the kernel (or to build llvm) in any case. The idea is to create an initrd directory containing nothing but a statically linked binary having a for-loop over a long-term sleep(). The result is a Linux kernel with almost no userspace: even the time-honored /dev, /lib, /tmp, and /usr directories are gone. In fact, the only directory present is "/", but only because I don't know how to get rid of it, at least short of not having an initrd in the first place. Although statically linked binaries are much maligned, and rightly so, their disadvantages seem to be irrelevant for this particular use case. From https://www.akkadia.org/drepper/no_static_linking.html: 1. Fixes are difficult to apply to hordes of widely scattered statically linked binaries. But in this case, there is only one binary, but there would otherwise be no fewer than four libraries. 2. Security measures like local address randomization cannot be used. Prudence prevents me from asserting that it is impossible to base a remote attack on a networking-free rcutorture instance. Nevertheless, bonus points to the first person who comes up with such an attack! 3. More efficient use of physical memory. Not in this case, given that libc is 1.8MB and the statically linked binary "only" 800K. 4. Features such as locales, name service switch (NSS), internationalized domain names (IDN) tool, and so on require dynamic linking. Bonus points to the first person coming up with a valid rcutorture use case requiring these features in its initrd. 5. Accidental violations of (L)GPL. Actually, this change actually helps -avoid- such violations by reducing the temptation to pass around tarballs of rcutorture-ready initrd directories. After all, the rcutorture scripts automatically create an initrd directory for you, so why bother with the tarballs? 6. Tools and hacks like ltrace, LD_PRELOAD, LD_PROFILE, and LD_AUDIT don't work. Again, bonus points to the first person coming up with a valid rcutorture use case requiring these features in its initrd. Nevertheless, the script will use dracut if available, and will create the statically linked binary only when dracut are missing. Those preferring the smaller initrd directory resulting from the statically linked binary (like me) are free to hand-edit mkinitrd.sh to remove the code using dracut. ;-) Signed-off-by: Paul E.

McKenney Date: Wed Jul 11 14:36:49 2018 -0700 rcu: Eliminate synchronize_rcu_mult() Now that synchronize_rcu() waits for both RCU read-side critical sections and preempt-disabled regions of code, the sole caller of synchronize_rcu_mult() can be replaced by synchronize_rcu(). This patch makes this change and removes synchronize_rcu_mult(). Note that _wait_rcu_gp() still supports synchronize_rcu_mult(), and thus might be simplified in the future to take only take a single call_rcu() function rather than the current list of them.

Next two patches allow early access to TLV-based capabilities during probe, previously the capabilities were parsed just before netdevs were registered, but its cleaner to do some basic validation earlier and avoid cleanup work. Next three patches improve RED's parameter validation. First we provide a more precise message about why offload failed (and move the parameter validation to a helper). Next we make sure we don't set the top bit in the 32 bit max RED threshold value. Because FW is treating the value as signed it reportedly causes slow downs (unnecessary queuing and marking) when top bit is set with recent firmwares. Last (and perhaps least importantly) we offload the harddrop parameter of the Qdisc.

But it doesn't include cases when an address of real device or vlan was reused by other vlans or vlan/macval devices. For handaling events when address was reused/unreused the patch adds new auxiliary routine - __hw_addr_ref_sync_dev().

But in some configurations, the READ MAC command for a Layer2 OSD device actually returns a pre-provisioned, virtual MAC address. So enable the READ MAC code to detect this situation, and let the L2 subdriver call READ MAC for OSD devices.

We can't easily use a lookup function as we did for VXLAN and GENEVE, as protocol error handlers, which would be in turn called by implementations of this new operation, handle the errors themselves, together with the tunnel lookup. Without a socket, we can't be sure which encapsulation error handler is the appropriate one: encapsulation handlers (the ones for FoU and GUE introduced in the next patch, e.g.) will need to check the new error codes returned by protocol handlers to figure out if errors match the given encapsulation, and, in turn, report this error back, so that we can try all of them in __udp{4,6}_lib_err_encap_no_sk() until we have a match. v2: - Name all arguments in err_handler prototypes (David Miller) Signed-off-by: Stefano Brivio Reviewed-by: Sabrina Dubroca Signed-off-by: David S.

Look up a socket with the original source and destination ports as found in the UDP packet inside the ICMP payload, this will work for tunnels that force the same destination port for both endpoints, i.e. VXLAN and GENEVE. Actually, lwtunnels could break this assumption if they are configured by an external control plane to have different destination ports on the endpoints: in this case, we won't be able to trace ICMP messages back to them. For IPv6 redirect messages, call ip6_redirect() directly with the output interface argument set to the interface we received the packet from (as it's the very interface we should build the exception on), otherwise the new nexthop will be rejected. There's no such need for IPv4. Tunnels can now export an encap_err_lookup() operation that indicates a match.

We have a few Qdiscs which can be fully offloaded today to the forwarding plane of switching devices. First patch adds a helper for handing statistic dumps, the code seems to be copy pasted between PRIO and RED. Second patch removes unnecessary parameter from RED offload function. Third patch makes the MQ offload use the dump helper which helps it behave much like PRIO and RED when it comes to the TCQ_F_OFFLOADED flag. Patch 4 adds a graft helper, similar to the dump helper. Patch 5 is unrelated to offloads, qdisc_graft() code seemed ripe for a small refactor - no functional changes there. Last two patches move the qdisc_put() call outside of the sch_tree_lock section for RED and PRIO. The child Qdiscs will get removed from the hierarchy under the lock, but having the put (and potentially destroy) called outside of the lock helps offload which may choose to sleep, and it should generally lower the Qdisc change impact. ==================== Signed-off-by: David S.

However, subparts_cpus will not be used at all in most use cases. So adding a new cpuset file that clutters the cgroup directory may not be desirable. This is now being done by using the hidden "cgroup_debug" kernel command line option to expose a new "cpuset.cpus.subpartitions" file. That option was originally used by the debug controller to expose itself when configured into the kernel. This is now extended to set an internal flag used by cgroup_addrm_files().

That can be a problem if a parent is a partition root with children partition roots. Changes to a parent's effective_cpus list due to changes in a child partition root may not be properly reflected in a child cpuset that use parent's effective_cpus because the cpu_exclusive rule of a partition root will not guard against that. In order to avoid the mismatch, two new tracking variables are added to the cpuset structure to track if a cpuset uses parent's effective_cpus and the number of children cpusets that use its effective_cpus. So whenever cpumask changes are made to a parent, it will also check to see if it has other children cpusets that use its effective_cpus and call update_cpumasks_hier() if that is the case.

That will then call update_parent_subparts_cpumask() if partitions are impacted. Currently, these events may cause update_parent_subparts_cpumask() to return error if none of the requested cpus are available or it will consume all the cpus in the parent partition root. Handling these errors is problematic as the states may become inconsistent. Instead of letting update_parent_subparts_cpumask() return error, a new error state (-1) is added to the partition_root_state flag to designate the fact that the partition is no longer valid. IOW, it is no longer a real partition root, but the CS_CPU_EXCLUSIVE flag will still be set as it can be changed back to a real one if favorable change happens later on. This new error state is set internally and user cannot write this new value to "cpuset.sched.partition".

This new flag, if set, indicates that the cgroup is the root of a new scheduling domain or partition that includes itself and all its descendants except those that are scheduling domain roots themselves and their descendants. With this new flag, one can directly create as many partitions as necessary without ever using the v1 trick of turning off load balancing in specific cpusets to create partitions as a side effect. This new flag is owned by the parent and will cause the CPUs in the cpuset to be removed from the effective CPUs of its parent. This is implemented internally by adding a new subparts_cpus mask that holds the CPUs belonging to child partitions so that: subparts_cpus | effective_cpus = cpus_allowed subparts_cpus & effective_cpus = 0 This new flag can only be turned on in a cpuset if its parent is a partition root itself. The state of this flag cannot be changed if the cpuset has children. Once turned on, further changes to "cpuset.cpus" is allowed as long as there is at least one CPU left that can be granted from the parent and a child partition root cannot use up all the CPUs in the parent's effective_cpus.

In the legacy hierarchy, scheduling partitions are supported indirectly via the right use of the load balancing and the exclusive CPUs flag which is not intuitive and can be hard to use. To fully support the concept of scheduling partitions in the default hierarchy, we need to add some new field into the cpuset structure as well as a new tmpmasks structure that is used to pre-allocate cpumasks at the top level cpuset functions to avoid memory allocation in inner functions as memory allocation failure in those inner functions may cause a cpuset to have inconsistent states.

The cpuset controller had experienced feature creep since its introduction more than a decade ago. Besides the core cpus and mems control files to limit cpus and memory nodes, there are a bunch of additional features that can be controlled from the userspace. Some of the features are of doubtful usefulness and may not be actively used. This patch enables cpuset controller in the default hierarchy with a minimal set of features, namely just the cpus and mems and their effective_* counterparts. We can certainly add more features to the default hierarchy in the future if there is a real user need for them later on. Alternatively, with the unified hiearachy, it may make more sense to move some of those additional cpuset features, if desired, to memory controller or may be to the cpu controller instead of staying with cpuset.

This is similar to min-spread between voltages of regulators, the difference is that the spread value isn't fixed. This means that extra carefulness is required for regulator "A" to drop its voltage without violating the requirement, hence its voltage should be changed in steps so that its couple "B" could follow (there is also max-spread requirement). Add new "max_uV_step" constraint that breaks voltage change into several steps, each step is limited by the max_uV_step value.

Since ioctl() request on loop devices is not frequent operation, we don't need fine grained locking. Let's use global lock in order to allow safe traversal at loop_validate_file(). Note that syzbot is also reporting circular locking dependency between bdev->bd_mutex and lo->lo_ctl_mutex [2] which is caused by calling blkdev_reread_part() with lock held.

If one of these devices temporarily requires higher voltage, there might occur a situation that the spread between two devices' voltages is so high, that there is a risk of changing 'high' and 'low' states on the interconnection between devices powered by those regulators. Introduce new function regulator_balance_voltage(), which keeps max_spread constraint fulfilled between a group of coupled regulators. It should be called if a regulator changes its voltage or after disabling or enabling. Disabled regulators should follow changes of the enabled ones, but their consumers' demands shouldn't be taken into account while calculating voltage of other coupled regulators. Find voltages, which are closest to suiting all the consumers' demands, while fulfilling max_spread constraint, keeping the following rules: - if one regulator is about to rise its voltage, rise others voltages in order to keep the max_spread - if a regulator, which has caused rising other regulators, is lowered, lower other regulators if possible - if one regulator is about to lower its voltage, but it hasn't caused rising other regulators, change its voltage so that it doesn't break the max_spread Change regulators' voltages step by step, keeping max_spread constraint fulfilled all the time. Function regulator_get_optimal_voltage() should find the best possible change for the regulator, which doesn't break max_spread constraint. In function regulator_balance_voltage() optimize number of steps by finding highest voltage difference on each iteration. If a regulator, which is about to change its voltage, is not coupled, method regulator_get_optimal_voltage() should simply return the lowest voltage fulfilling consumers' demands. Coupling should be checked only if the system is in PM_SUSPEND_ON state.

Make this a bit nicer for userspace by interpolating the position using the CPU clock. The overhead is small -- an extra ktime_get() every time a GPU message is sent -- and another call and a few calculations whenever the delay is sought from userland. At 48,000 frames per second, i.e. approximately 20 microseconds per frame, it would take a clock inaccuracy of 20 microseconds in 10 milliseconds -- 2,000 parts per million -- to result in an inaccurate estimate, whereas crystal- or resonator-based clocks typically have an inaccuracy of 10s to 100s of parts per million.

That resulted in commit 9a40ac86152c ("ARM: 6164/1: Add kto and kfrom to input operands list."). Yet that commit has problems of its own by having assembly operand constraints completely wrong. If the generated code has been OK since then, it is due to luck rather than correctness. So this patch also provides proper assembly operand constraints, and removes two instances of redundant register usages in the implementation while at it. Inspection of the generated code with this patch doesn't show any obvious quality degradation either, so not relying on __naked at all will make the code less fragile, and avoid some issues with clang. The only remaining __naked instances (excluding the kprobes test cases) are exynos_pm_power_up_setup(), tc2_pm_power_up_setup() and cci_enable_port_for_self(. But in the first two cases, only the function address is used by the compiler with no chance of inlining it by mistake, and the third case is called from assembly code only. And the fact that no stack is available when the corresponding code is executed does warrant the __naked usage in those cases.

If we let VLANs have the same tunnel offload capabilities as their lower device, throughput can improve significantly when CPU is limited on the transmitter side. - set NETIF_F_GSO_ENCAP_ALL bits in the VLAN 'hw_features', to ensure that 'features' will have those bits zeroed only when the lower device has no hardware support for tunnel encapsulation. - for the same reason, copy GSO-related bits of 'hw_enc_features' from lower device to VLAN, and ensure to update that value when the lower device changes its features. - set NETIF_F_HW_CSUM bit in the VLAN 'hw_enc_features' if 'real_dev' is able to compute checksums at least for a kind of packets, like done with commit 8403debeead8 ("vlan: Keep NETIF_F_HW_CSUM similar to other software devices").

Historically these had 16 bit offsets, but microMIPS & MIPS32/MIPS64r6 onwards reduced the width of the offset field. GCC 4.9 & higher supports a ZC constraint which matches the offset requirements of the LL & SC instructions. Where supported we can use the ZC constraint regardless of ISA, and it will handle the requirements of the ISA correctly. As such we require 3 cases: - GCC 4.9 & higher can use ZC. - GCC older than 4.9 must use the older R constraint, which does not take into account microMIPS or MIPSr6. - microMIPS builds therefore require GCC 4.9 or higher. MIPSr6 support was only introduced in newer compilers anyway so it can be ignored here. The current code complicates this a little by specifically having MIPSr6 bypass the GCC version check, and using the R constraint for pre-MIPSr6 builds even if the compiler supports ZC which would be equivalent. Simplify this such that the code straightforwardly implements the 3 cases outlined above. For non-GCC compilers we presume that ZC is safe to use. In practice the only non-GCC compiler of interest is clang and it has supported the ZC constraint since version 3.7.0. It seems safe enough to presume that nobody will expect to built a working kernel using a clang version older than that, and if they do then they'll have bigger problems. As such we don't check the clang version number & just presume ZC is usable when the compiler is not GCC.

The core functionality is implemented by the second patch, introducing a new sockopt to enable UDP_GRO, while patch 3 implements support for passing the segment size to the user space via a new cmsg. UDP GRO performs a socket lookup for each ingress packets and aggregate datagram directed to UDP GRO enabled sockets with constant l4 tuple. UDP GRO packets can land on non GRO-enabled sockets, e.g. due to iptables NAT rules, and that could potentially confuse existing applications. The solution adopted here is to de-segment the GRO packet before enqueuing as needed. Since we must cope with packet reinsertion after de-segmentation, the relevant code is factored-out in ipv4 and ipv6 specific helpers and exposed to UDP usage. While the current code can probably be improved, this safeguard ,implemented in the patches 4-7, allows future enachements to enable UDP GSO offload on more virtual devices eventually even on forwarded packets. The last 4 for patches implement some performance and functional self-tests, re-using the existing udpgso infrastructure. The problematic scenario described above is explicitly tested.

One cannot have multiple service instances running in the default and other VRFs for services that are not VRF-aware and listen on an unbound socket. This is because there is no easy way of isolating packets received in the default VRF from those arriving in other VRFs. This series provides this isolation for stream sockets subject to the existing kernel parameter net.ipv4.tcp_l3mdev_accept not being set, given that this is documented as allowing a single service instance to work across all VRF domains. Similarly, net.ipv4.udp_l3mdev_accept is checked for datagram sockets, and net.ipv4.raw_l3mdev_accept is introduced for raw sockets. The functionality applies to UDP & TCP services as well as those using raw sockets, and is for IPv4 and IPv6.

This results in the packet being delivered over both sockets, instead of only the raw socket bound to the VRF. The bound device checks in __raw_v4_lookup() are replaced with a call to raw_sk_bound_dev_eq() which correctly handles whether the packet should be delivered over the unbound socket in such cases. In __raw_v6_lookup() the match on the device binding of the socket is similarly updated to use raw_sk_bound_dev_eq() which matches the handling in __raw_v4_lookup(). Importantly raw_sk_bound_dev_eq() takes the raw_l3mdev_accept sysctl into account.

This allows e.g. older ping implementations to be run with specifying the device but without executing it in the VRF. If the option is disabled, packets received in a VRF context are only handled by a raw socket bound to the VRF, and correspondingly packets in the default VRF are only handled by a socket not bound to any VRF.

The check for a device match in compute_score() for UDP must be performed when there is no device match. For this, a failure is returned when there is no device match. This ensures that bound sockets are never selected, even if there is no unbound socket. Allow IPv6 packets to be sent over a datagram skt bound to a VRF. These packets are currently blocked, as flowi6_oif was set to that of the master vrf device, and the ipi6_ifindex is that of the slave device. Allow these packets to be sent by checking the device with ipi6_ifindex has the same L3 scope as that of the bound device of the skt, which is the master vrf device. Note that this check always succeeds if the skt is unbound. Even though the right datagram skt is now selected by compute_score(), a different skt is being returned that is bound to the wrong vrf. The difference between these and stream sockets is the handling of the skt option for SO_REUSEPORT. While the handling when adding a skt for reuse correctly checks that the bound device of the skt is a match, the skts in the hashslot are already incorrect. So for the same hash, a skt for the wrong vrf may be selected for the required port. The root cause is that the skt is immediately placed into a slot when it is created, but when the skt is then bound using SO_BINDTODEVICE, it remains in the same slot. The solution is to move the skt to the correct slot by forcing a rehash. Signed-off-by: Mike Manning Reviewed-by: David Ahern Tested-by: David Ahern Signed-off-by: David S.

Unfortunately, we copy the entire struct dlm_lksb to the result struct, which is then copied to userspace at the end of the function, leaking the contents of sb_lvbptr, which is a valid kernel pointer in some cases (indeed, later in the same function the data it points to is copied to userspace). It is an error to leak kernel pointers to userspace, as it undermines KASLR protections (see e.g. 65eea8edc31 ("floppy: Do not copy a kernel pointer to user memory in FDGETPRM ioctl") for another example of this).

It also allowed building a driver that didn't actually work for a system that has non-volatile DIMMs. Arnd Bergmann pointed out that the right fix is to make EDAC_SKX "depend on ACPI".

This can be an issue when creating large BPF maps and/or loading many programs. A workaround is to raise this limit for the current process before trying to create a new BPF map. Changing the hard limit requires the CAP_SYS_RESOURCE and can usually only be done by root user (for non-root users, a call to setrlimit fails (and sets errno) and the program simply goes on with its rlimit unchanged). There is no API to get the current amount of memory locked for a user, therefore we cannot raise the limit only when required. One solution, used by bcc, is to try to create the map, and on getting a EPERM error, raising the limit to infinity before giving another try. Another approach, used in iproute2, is to raise the limit in all cases, before trying to create the map. Here we do the same as in iproute2: the rlimit is raised to infinity before trying to load programs or to create maps with bpftool.

For the test_l4lb_noinline, uncomment related tests from test_libbpf.c and remove the associated "TODO". For tracex3_kern.o, instead of loading a program from samples/bpf/ that might not have been compiled at this stage, try loading a program from BPF selftests. Since this test case is about loading a program compiled without the "-target bpf" flag, change the Makefile to compile one program accordingly (instead of passing the flag for compiling all programs). Regarding test_xdp_noinline.o: in its current shape the program fails to load because it provides no version section, but the loader needs one. The test was added to make sure that libbpf could load XDP programs even if they do not provide a version number in a dedicated section. But libbpf is already capable of doing that: in our case loading fails because the loader does not know that this is an XDP program (it does not need to, since it does not attach the program). So trying to load test_xdp_noinline.o does not bring much here: just delete this subtest. For the record, the error message obtained with tracex3_kern.o was fixed by commit e3d91b0ca523 ("tools/libbpf: handle issues with bpf ELF objects containing .eh_frames") I have not been abled to reproduce the "libbpf: incorrect bpf_call opcode" error for test_l4lb_noinline.o, even with the version of libbpf present at the time when test_libbpf.sh and test_libbpf_open.c were created. RFC -> v1: - Compile test_xdp without the "-target bpf" flag, and try to load it instead of ../../samples/bpf/tracex3_kern.o. - Delete test_xdp_noinline.o subtest.

It's much easier to flood the queue with writes and reduce the read servicing. Implement two queue maps, one for reads and one for writes. The write queue count is configurable through the 'write_queues' parameter. By default, we retain the previous behavior of having a single queue set, shared between reads and writes. Setting 'write_queues' to a non-zero value will create two queue sets, one for reads and one for writes, the latter using the configurable number of queues (hardware queue counts permitting).

Within the last couple of days, I got a bug report from one of our customers who had been having issues with their machine suddenly booting up very slowly after having updated. The amount of time it took to boot went from around 30 seconds, to over 6 minutes consistently. After some investigation, I discovered that i915 was reporting massive amounts of short HPD IRQ spam on this system from the DisplayPort port, despite there not being anything actually connected.

So, workaround this impressively broken hardware by changing the default HPD storm threshold from 5 to 50. Then, make long IRQs count for 10, and short IRQs count for 1. This makes it so that 5 long IRQs will trigger an HPD storm, and on systems with short HPD storm detection 50 short IRQs will trigger an HPD storm. 50 short IRQs amounts to 100ms of constant pulsing, which seems like a good middleground between being too sensitive and not being sensitive enough (which would cause visible stutters in userspace every time a storm occurs). And just to be extra safe: we don't enable this by default on systems with MST support. There's too high of a chance of MST support triggering storm detection, and systems that are new enough to support MST are a lot less likely to have issues with IRQ storms anyway. As a note: this patch was tested using a ThinkPad T450s and a Chamelium to simulate the short IRQ storms. Changes since v1: - Don't use two separate thresholds, just make long IRQs count for 10 each and short IRQs count for 1.

This results in us only enabling storm detection when we go +2 above the threshold, e.g. an HPD threshold of 5 would not trigger a storm until we reach a total of 7 hotplugs. So: rework the code a bit so we reset the HPD count when HPD_STORM_DETECT_DELAY has passed, then increment the count afterwards. Also, clean things up a bit to make it easier to undertand.

For example, an higher-level reset event occurs, memory allocation failure, hardware reset timeout, etc. Therefore, it is necessary to add corresponding error handling for these situations. 1. A high-level reset is required due to a high-level reset failure. 2. For memory allocation failure, a high-level reset is initiated by the timer to recover. The reason for using the timer is to prevent this new high-level reset to interrupt the reset process of other pf/vf; 3. For the case of hardware reset timeout, reschedule the reset task to wait for the hardware to complete the reset. For memory allocation failure and reset timeouts, in order to prevent an infinite number of scheduled reset tasks, the number of error recovery needs to be limited. This patch also add some reset related debug log printing. Signed-off-by: Huazhong Tan Signed-off-by: David S.

This causes an underflow in the timecounter and the PHC time jumps hours ahead. This was observed on 82574, I217 and I219. The fastest way to reproduce it is to run a program that continuously calls the PTP_SYS_OFFSET ioctl on the PHC. Modify e1000e_phc_gettime() to use timecounter_cyc2time() instead of timecounter_read() in order to allow non-monotonic SYSTIM readings and prevent the PHC from jumping.

After some experiments with adding pipecontrols (a lot of pipecontrols (32) as gen4/5 do not have a bit to wait on earlier pipe controls or even the current on), it was discovered that we merely needed to delay the EMIT_INVALIDATE by several flushes. It is important to note that it is the EMIT_INVALIDATE as opposed to the EMIT_FLUSH that needs the delay as opposed to what one might first expect -- that the delay is required for the TLB invalidation to take effect (one presumes to purge any CS buffers) as opposed to a delay after flushing to ensure the writes have landed before triggering invalidation.

The behavior of this key on Windows, with the ATKACPI driver from Asus installed, is turning off the backlight of all connected displays with a fading effect, and any cursor input or key press turning the backlight back on. The key press or cursor input that wakes up the display is also passed through to the application under the cursor or under focus. The key that matches this behavior the closest is KEY_SCREENLOCK.

These are currently mapped to KEY_DISPLAYTOGGLE and KEY_DISPLAY_OFF, respectively. Most recently the EC on Asus most machines lost ability to toggle the LCD backlight directly, but unless the OS informs the firmware it is going to handle the display toggle hotkey events, the firmware still tries change the brightness through the EC, to no effect. The end result is a long list (at Endless we counted 11) of Asus laptop models where the display toggle hotkey does not perform any action. Our firmware engineers contacts at Asus were surprised that there were still machines out there with the old behavior. Calling WMNB(ASUS_WMI_DEVID_BACKLIGHT==0x00050011, 2) on the _WDG device tells the firmware that it should let the OS handle the display toggle event, in which case it will simply notify the OS of a key press with 0x35, as shown by the DSDT excerpts bellow.

Some commands returning port information are updated to additionally provide trunking information. And new ACQEs are generated to report physical link events relative to the trunk. This patch contains the following modifications: - Added link speed settings of 128GB and 256GB. - Added handling of trunk-related ACQEs, mainly logging and trapping of physical link statuses. - Added additional bsg interface to query trunk state by applications. - Augment link_state sysfs attribtute to display trunk link status Signed-off-by: Dick Kennedy Signed-off-by: James Smart Reviewed-by: Hannes Reinecke Signed-off-by: Martin K.

While reviewing the LOGO handling a few other issues were seen and were addressed: - Better lock synchronization around ndlp data types - When the ABTS times out, unregister the RPI before sending the LOGO so that all local exchange contexts are cleared and nothing received while awaiting LOGO/PLOGI handling will be accepted. - LOGO handling optimized to: Wait only R_A_TOV for a response. It doesn't need to be retried on timeout. If there wasn't a response, a PLOGI will be sent, thus an implicit logout applies as well when the other port sees it. If there is a response, any kind of response is considered "good" and the XRI quarantined for a exchange qualifier window. - PLOGI is issued as soon a LOGO state is resolved.

And if there are no IOs running, since we only check the FW state as part of ISR code, fault goes undetected by driver and OCR will not be triggered.

On large systems with multiple devices of the same class (e.g. NVMe disks, using managed interrupts), the kernel can affinitize these interrupts to a small subset of CPUs instead of spreading them out evenly. irq_matrix_alloc_managed() tries to select the CPU in the supplied cpumask of possible target CPUs which has the lowest number of interrupt vectors allocated. This is done by searching the CPU with the highest number of available vectors. While this is correct for non-managed CPUs it can select the wrong CPU for managed interrupts. Under certain constellations this results in affinitizing the managed interrupts of several devices to a single CPU in a set. The book keeping of available vectors works the following way: 1) Non-managed interrupts: available is decremented when the interrupt is actually requested by the device driver and a vector is assigned. It's incremented when the interrupt and the vector are freed. 2) Managed interrupts: Managed interrupts guarantee vector reservation when the MSI/MSI-X functionality of a device is enabled, which is achieved by reserving vectors in the bitmaps of the possible target CPUs. This reservation decrements the available count on each possible target CPU. When the interrupt is requested by the device driver then a vector is allocated from the reserved region. The operation is reversed when the interrupt is freed by the device driver. Neither of these operations affect the available count. The reservation persist up to the point where the MSI/MSI-X functionality is disabled and only this operation increments the available count again. For non-managed interrupts the available count is the correct selection criterion because the guaranteed reservations need to be taken into account. Using the allocated counter could lead to a failing allocation in the following situation (total vector space of 10 assumed): CPU0 CPU1 available: 2 0 allocated: 5 3 <--- CPU1 is selected, but available space = 0 managed reserved: 3 7 while available yields the correct result. For managed interrupts the available count is not the appropriate selection criterion because as explained above the available count is not affected by the actual vector allocation. The following example illustrates that. Total vector space of 10 assumed. The starting point is: CPU0 CPU1 available: 5 4 allocated: 2 3 managed reserved: 3 3 Allocating vectors for three non-managed interrupts will result in affinitizing the first two to CPU0 and the third one to CPU1 because the available count is adjusted with each allocation: CPU0 CPU1 available: 5 4 <- Select CPU0 for 1st allocation --> allocated: 3 3 available: 4 4 <- Select CPU0 for 2nd allocation --> allocated: 4 3 available: 3 4 <- Select CPU1 for 3rd allocation --> allocated: 4 4 But the allocation of three managed interrupts starting from the same point will affinitize all of them to CPU0 because the available count is not affected by the allocation (see above). So the end result is: CPU0 CPU1 available: 5 4 allocated: 5 3 Introduce a "managed_allocated" field in struct cpumap to track the vector allocation for managed interrupts separately. Use this information to select the target CPU when a vector is allocated for a managed interrupt, which results in more evenly distributed vector assignments. The above example results in the following allocations: CPU0 CPU1 managed_allocated: 0 0 <- Select CPU0 for 1st allocation --> allocated: 3 3 managed_allocated: 1 0 <- Select CPU1 for 2nd allocation --> allocated: 3 4 managed_allocated: 1 1 <- Select CPU0 for 3rd allocation --> allocated: 4 4 The allocation of non-managed interrupts is not affected by this change and is still evaluating the available count. The overall distribution of interrupt vectors for both types of interrupts might still not be perfectly even depending on the number of non-managed and managed interrupts in a system, but due to the reservation guarantee for managed interrupts this cannot be avoided. Expose the new field in debugfs as well.

Currently the information is passed using pdata specific to each plaform driver. This prevents other drivers, such as SOF, from reusing machine drivers directly. Add a new structure which contains the required fields. This proposal requires a bit more work on the platform side but this generic interface helps reuse code directly.

That's not really a problem, all userspace gets is a slightly dysfunctional lease with the current code. But this might change, and gcc might decide to reload a few too many times, and then boom. So better safe than sorry. v2: Remove the now unused lessor_priv argument from validate_lease() (Keith). v3: Actually add everything ... silly me.

I had tried to fix the problem of having both coexist earlier, but my patch only prevented them from being built-in. This is because of a special Kconfig feature that lets a symbol have a dependency on another one being disabled, but still allow both to be loadable modules. Changing the dependency to =n avoids that problem, now we can only build the new driver if the old one is completely disabled. If we could figure out a way to let rename one of the reset functions and have each driver link to exactly the old or the compat code, that would also work, but I could not find if that's possible.

I've tested the different known "worldwide" ccode-s used in various nvram sources with the latest firmwares from linux-firmware for various brcmfmac models, here is a simplified (*) table with what each setting results in: ALL: 12-14 disab, U-NII-1, U-NII-2 no-IR/radar, U-NII-3 XV: 12-14 no-IR, disables all 5G channels XY: 12-13 enab, 14 disab, U-NII-1 enab, U-NII-2 no-IR/radar, U-NII-3 disab X2: 12-13 no-IR, 14 dis, U-NII-1 no-IR, U-NII-2 no-IR/radar, U-NII-3 no-IR Where 12,13,14 are 2.4G channels 12-14 and U-NII-1/2/3 are the 3 different 5G channel groups. no-IR is no-Initiate-Radiation, we will never send on these channels without first having received valid wifi traffic there. This immediately shows that both ALL and XV are not as worldwide as we want them to be. ALL causes channels 12 and 13 to not be available and XV causes all 5GHz channels to not be available. Also ALL unconditionally enables the U-NII-1 and U-NII-3 5G groups, while we really should be using no-IR for these. This commit replace XV and ALL with X2, which allows usage of chan 12-13 and 5G channels, but only after receiving valid wifi traffic there first.

Round these ranges down to the nearest volt, and provide a 0.05V margin. The regulator should provide its own supported ranges, which will helpfully intersect with these ranges.

It turns out that there isn't really much driver-specific business involved there, so now that the default implementation is mandatory let's just improve that - the main thing we're after is to use larger pages wherever possible, and as long as domain->pgsize_bitmap reflects reality, iommu_map() can already do that in a generic way. All we need to do is detect physically-contiguous segments and batch them into a single map operation, since whatever we do here is transparent to our caller and not bound by any segment-length restrictions on the list itself. Speaking of efficiency, there's really very little point in duplicating the checks that iommu_map() is going to do anyway, so those get cleared up in the process.

The provided samples use small values for XOFFSET, XPULSE, YOFFSET and YPULSE, where the error doesn't occur.

Usage: perf stat -e rXYZ ./app X: the index of performance counter. YZ: the index(convert to hexdecimal) of events Example: 'perf stat -e r101 ./app' means the counter 1 will count the instruction event. The index of counter and events can be found in "Andes System Privilege Architecture Version 3 Manual". Or you can perform the 'perf list' to find the symbolic name of raw events. 2.Perf mmap2: Fix unexpected perf mmap2() page fault When the mmap2() called by perf application, you will encounter such condition:"failed to write." With return value -EFAULT This is due to the page fault caused by "reading" buffer from the mapped legal address region to write to the descriptor. The page_fault handler will get a VM_FAULT_SIGBUS return value, which should not happens here.(Due to this is a read request.) You can refer to kernel/events/core.c:perf_mmap_fault(...) If "(vmf->pgoff && (vmf->flags & FAULT_FLAG_WRITE))" is evaluated as true, you will get VM_FAULT_SIGBUS as return value. However, this is not an write request. The flags which indicated why the page fault happens is wrong. Furthermore, NDS32 SPAv3 is not able to detect it is read or write. It only know either it is instruction fetch or data access. Therefore, by removing the wrong flag assignment(actually, the hardware is not able to show the reason), we can fix this bug. 3.Perf multiple events map to same counter. When there are multiple events map to the same counter, the counter counts inaccurately. This is because each counter only counts one event in the same time. So when there are multiple events map to same counter, they have to take turns in each context. There are two solution: 1. Print the error message when multiple events map to the same counter. But print the error message would let the program hang in loop. The ltp (linux test program) would be failed when the program hang in loop. 2. Don't print the error message, the ltp would pass. But the user need to have the knowledge that don't count the events which map to the same counter, or the user will get the inaccurate results.

Also, the gpio-addr-flash driver is unused since the removal of the blackfin arch in v4.17, so we can safely remove the old driver without risking breaking existing boards.

Eventually, the last consumer of the function was removed[2], but the function itself was kept, perhaps even intentionally as a form of documentation. Remove get_scattered_cpuid_leaf() as it is currently not used by KVM. Furthermore, simply rebuilding the "real" leaf does not resolve all of KVM's woes when it comes to exposing a scattered CPUID feature, i.e. keeping the function as documentation may be counter-productive in some scenarios, e.g. when KVM needs to do more than simply expose the leaf.

That means ilk_wm_merge() & co. will keep considering the any pipe that is getting disabled as still enabled. Thus we either get no LP1+ watermakrs (ilk-ivb), or we get suboptimal ones (hsw-bdw). This seems to have been broken by commit b6b178a77210 ("drm/i915: Calculate ironlake intermediate watermarks correctly, v2."). Before that we apparently had some difference between the intermediate and optimal watermarks and so we would program the optiomal ones. Now intermediate and optimal are identical for disabled pipes and so we don't program either. Fix this by programming the intermediate watermarks even for disabled pipes. We were already doing that for skl+. We'll leave out gmch platforms for now since those do the merging in a different manner and should work as is. We'll want to unify this eventually, but play it safe for now and just put in a FIXME.

Fix is not easy though: 1. allowing will not work because IGAM is before ICSC so RGB gamma would be applied on YUV pixels. 2. Moving OS gamma to DGAM or RGAM resulted in weird artifacts. Ultimately the root cause for these artifacts was due to handling end points and the fact that YUV->RGB conversion will frequently "overshoot" FP 1.0 value. DCE has a single end point and slope, so we would take max. In nightlight mode, blue channel is reduced, sometimes to flat 0 line, but red is virtually unchanged. Any "overshot" in blue will be clipped to 1 (max R,G,B) instead of max blue value. [How] Fortunately, this can be fixed on DCN where we have end point and slope for all three color channels. We cannot fix this problem on DCE. Other things fixed: - switch (back) to using RGAM for OS gamma instead of IGAM - add coeffs for 709 YUV->RGB (we used RGB->YUV for both conversions) - switch color temperature method to scaled bradford - otherwise we would have clipping problems that caused us to switch to IGAM for OS gamma in the first place. - comments and some minor improvements - there are some more issues but they will be addressed in separate commits.

Tiling requires a bilinear interpolator reset at each tile start, which causes the image to be slightly shifted if the starting pixel should not have been sampled from an integer pixel position in the source image according to the full image resizing ratio. To work around this hardware limitation, calculate per-tile resizing coefficients that make sure that the correct input pixels are sampled at the tile end.

This involves setting ctx->aborting to true unconditionally so that no new job runs can be queued during unprepare, and holding the ctx->aborting flag until the context is freed. Note that the "normal" ipu_image_convert_abort() case (e.g. not during context unprepare) should clear the ctx->aborting flag after aborting any active run and clearing the context's pending queue. This is because it should be possible to continue to use the conversion context and queue more runs after an abort.

This was changed after following commits for previous and current LPSS platforms: c78b0830667a ("ACPI / LPSS: custom power domain for LPSS") 41a3da2b8e16 ("mfd: intel-lpss: Save register context on suspend") However there is one caveat: There is no LPSS private register context save/restore for the Intel Lynxpoint in the Linux kernel code. I did some debugging on one Lynxpoint based device I have and on it the LPSS register context is not lost over suspend/resume cycle (s2idle). Which happens for instance on Intel Braswell. I'm speculating but I guess either firmware does it or the LPSS is kept always on Lynxpoint. Given that we haven't needed to implement Lynxpoint LPSS I2C or UART private register context save/restore over four years time I think we are safe to remove this LPSS private register restoring during resume here.

However, there is no check to see if the spi clock was actually set that high and no way to dynamically lower the spi clock rate again. So it seems any potiential users of this functionality are better off just setting the spi clock rate at init using the assigned-clock-rates devicetree property. Removing this dynamic spi clock rate raising allows us let the spi framework handle min/max speeds for us.

We can not trick the system by using the DRR2/DXR2 register offset and use 32bit element size since these (and other McBSP) registers are 16bit ones. We would need support for port_window in cyclic mode from the sDMA driver, but it is not straight forward as we would need to have the sDMA frame to cover the 32bit (DRR2+DRR1/DXR2+DXR1), but the frames must cover the ALSA period to be able to receive periodic interrupts. Since the 32bit samples are not working (DMA timeout), just remove it in case we have McBSP with reg_size of 2.

The reason is, that the spreading code starts from node 0 and continues up to the number of interrupts requested for allocation. This leaves the nodes past the last interrupt unused. This results in interrupt concentration on the first nodes which violates the assumption of the block layer that all nodes are covered evenly. As a consequence the NUMA nodes above the number of interrupts are all assigned to hardware queue 0 and therefore NUMA node 0, which results in bad performance and has CPU hotplug implications, because queue 0 gets shut down when the last CPU of node 0 is offlined. Go over all NUMA nodes and assign them round-robin to all requested interrupts to solve this.

The HL2.0 firmware sends only one channel info event per channel which is scanned without the COMPLETE flag set. After sending the chan_info_event for all the channels, the HL2.0 firmware sends a chan_info_event with COMPLETE flag set to indicate the completion of the channel info event. The firmware does not indicate this behavior with any service bitmap and hence a new firmware feature flag is used to handle the modified parsing of the channel info events, in the host driver, for the firmware which sends single channel info event per scanned channel.

Spinlocks become sleeping locks with CONFIG_PREEMPT_RT_FULL=y, therefore invocation of one of the callbacks in atomic context may cause a hard lockup if at least two GPIO pins in the same bank are used as interrupts. The issue doesn't occur with just a single interrupt pin per bank because the lock is never contended. I'm experiencing such lockups with GPIO 8 and 28 used as level-triggered interrupts, i.e. with ->irq_disable being invoked on reception of every IRQ. The critical section protected by the spinlock is very small (one bitop and one RMW of an MMIO register), hence converting to a raw spinlock seems a better trade-off than converting the driver to threaded IRQ handling (which would increase latency to handle an interrupt).

This results in random freezes during boot when cpufreq is enabled, probably due to wrong voltages. This patch (more or less copy/paste from 06139c) does the following things on this board: - enable r_i2c - add sy8106a to the r_i2c bus - have the sy8106a regulate VDD of cpu Since the Orange Pi Plus has the same PMU setup as the Orange Pi PC, I simply took min/max/fixed/ramp from the latter DTS. In that file the origin of the values are described by the following comment: "The datasheet uses 1.1V as the minimum value of VDD-CPUX, however both the Armbian DVFS table and the official one have operating points with voltage under 1.1V, and both DVFS table are known to work properly at the lowest operating point. Use 1.0V as the minimum voltage instead." I have tested this on patch two Orange Pi Plus boards, by running a kernel with this patch and do intermettent runs of cpuburn while monitoring voltage, frequency and temperature. The board runs stable across its operatiing points while showing a reasonable (< 40C) temperature. My Orange Pi PC, when put to the same test, yields similar stable results.

A new internal routine _set_required_opps() takes care of updating performance state for all the required OPPs. With this the performance state updates are supported even when the end device needs to configure regulators as well, that wasn't the case earlier. The pstates were earlier stored in the end device's OPP structures, that also changes now as those values are stored in the genpd's OPP structures. And so we switch over to using pm_genpd_opp_to_performance_state() instead of of_genpd_opp_to_performance_state() to get performance state for the genpd OPPs. The routine _generic_set_opp_domain() is not required anymore and is removed. On errors we don't try to recover by reverting to old settings as things are really complex now and the calls here should never really fail unless there is a bug. There is no point increasing the complexity, for code which will never be executed. Reviewed-by: Ulf Hansson Signed-off-by: Viresh Kumar commit 4f018bc0e1cfdec2e25072db9fecc1f363ba79ea Author: Viresh Kumar Date: Tue Jun 26 16:29:34 2018 +0530 OPP: Add dev_pm_opp_{set|put}_genpd_virt_dev() helper Multiple generic power domains for a consumer device are supported with the help of virtual devices, which are created for each consumer device - genpd pair. These are the device structures which are attached to the power domain and are required by the OPP core to set the performance state of the genpd. The helpers added by this commit are required to be called once for each of these virtual devices. These are required only if multiple domains are available for a device, otherwise the actual device structure will be used instead by the OPP core. The new helpers also support the complex cases where the consumer device wouldn't always require all the domains. For example, a camera may require only one power domain during normal operations but two during high resolution operations. The consumer driver can call dev_pm_opp_put_genpd_virt_dev(high_resolution_genpd_virt_dev) if it is currently operating in the normal mode and doesn't have any performance requirements from the genpd which manages high resolution power requirements. The consumer driver can later call dev_pm_opp_set_genpd_virt_dev(high_resolution_genpd_virt_dev) once it switches back to the high resolution mode. The new helpers differ from other OPP set/put helpers as the new ones can be called with OPPs initialized for the table as we may need to call them on the fly because of the complex case explained above. For this reason it is possible that the genpd virt_dev structure may be used in parallel while the new helpers are running and a new mutex is added to protect against that. We didn't use the existing opp_table->lock mutex as that is widely used in the OPP core and we will need this lock in the dev_pm_opp_set_rate() helper while changing OPP and we need to make sure there is not much contention while doing that as that's the hotpath.

The third one is the virtual device structures created by the genpd core to represent the consumer device for multiple power domain case, currently named as genpd_dev.

In rt.c, the code at 1) is in the _pick_next_task_rt() and the code at 2) is in the pick_next_task_rt(). If we put two operations in one function, maybe better. So, we introduce a new function set_next_task(), which is responsible for doing the above. By introducing the function we can get rid of calling the dequeue_pushable(_dl)_task() directly(We can call set_next_task()) in pick_next_task() and have better code readability and reuse. In set_curr_task_rt(), we also can call set_next_task(). Do this things such that we end up with: static struct task_struct *pick_next_task(struct rq *rq, struct task_struct *prev, struct rq_flags *rf) { /* do something else ... */ put_prev_task(rq, prev); /* pick next task p */ set_next_task(rq, p); /* do something else ... */ } put_prev_task() can match set_next_task(), which can make the code more readable.

However, idle_balance() pays no attention to sd->balance_interval, yet it will still lead to an increase in balance_interval in case of pinned tasks. If we're going through several newidle balances (e.g. we have a periodic task), this can lead to a huge increase of the balance_interval in a very small amount of time. To prevent that, don't increase the balance interval when going through a newidle balance. This is a similar approach to what is done in commit 58b26c4c0257 ("sched: Increment cache_nice_tries only on periodic lb"), where we disregard newidle balance and rely on periodic balance for more stable results.

What's implemented here is to add three new members to drm_format_info that could describe such formats: - char_per_block[3] - block_w[3] - block_h[3] char_per_block will be put in a union alongside cpp, for transparent compatibility with the existing format descriptions. Regarding, block_w and block_h they are intended to be used through their equivalent getters drm_format_info_block_width / drm_format_info_block_height, the reason of the getters is to abstract the fact that for normal formats block_w and block_h will be unset/0, but the methods will be returning 1. Additionally, convenience function drm_format_info_min_pitch had been added that computes the minimum required pitch for a given pixel format and buffer width. Using that the following drm core functions had been updated to generically handle both block and non-block formats: - drm_fb_cma_get_gem_addr: for block formats it will just return the beginning of the block. - framebuffer_check: Use the newly added drm_format_info_min_pitch. - drm_gem_fb_create_with_funcs: Use the newly added drm_format_info_min_pitch. - In places where is not expecting to handle block formats, like fbdev helpers I just added some warnings in case the block width/height are greater than 1. Changes since v3: - Add helper function for computing the minimum required pitch. - Improve/cleanup documentation Changes since v8: - Fixed build on 32bits arm architectures, with: - return DIV_ROUND_UP((u64)buffer_width * info->char_per_block[plane], + return DIV_ROUND_UP_ULL((u64)buffer_width * info->char_per_block[plane], Reviewed-by: Brian Starkey Reviewed-by: Daniel Vetter Signed-off-by: Alexandru Gheorghe Link: https://patchwork.freedesktop.org/patch/msgid/20181101170055.5433-1-alexandru-cosmin.gheorghe@arm.com commit fcec4163afa5f32a4aa31245a699c743fa33e2e7 Author: Linus Walleij Date: Fri Oct 26 13:13:34 2018 +0200 drm/panel: Add simple panel mode for the ARM RTSM Having failed any attempts at a more generic solution, I fall back to the very specific solution: define a simple panel for the ARM RTSM emulated platforms.

However, the palette registers are only used in one function, i9xx_load_luts_internal(), and only for GMCH platforms, wasting device info. Replace palette_offsets with _PICK() in palette register definition. While the use of _PICK() does not check for pipe C existence, neither does the current offset array usage, and leads to bogus address when pipe C is passed to PALETTE() on non-CHV. Using _PICK() at least leads to a sensible register offset, just non-existing on non-CHV. Either way, this shouldn't happen anyway. Remove unused old palette macros while at it.

When the panel-driver is build as a module it currently fails hard as the panel cannot be probed directly: dw_mipi_dsi_bind() __dw_mipi_dsi_probe() creates dsi bus creates panel device triggers panel module load panel not probed (module not loaded or panel probe slow) drm_bridge_attach fails with -EINVAL due to empty panel_bridge Additionally the panel probing can run concurrently with dsi bringup making it possible that the panel can already be found but dsi-attach hasn't finished running. To solve that cleanly we may want to only create the component after the panel has finished probing, by calling component_add from the host-attach dsi callback. As that is specific to glue drivers, add a new struct for host_ops so that glue drivers can tell the bridge to call specific functions after the common host-attach and before the common host-detach run.

Drivers using the component framework may instead want to call dw_mipi_dsi_probe separately in their probe function to setup resources early.

With i915 as the supplier and HDA as the consumer the PM framework will guarantee the HDA->i915 suspend (and shutdown) and i915->HDA resume order. Atm, the lack of this ordering is not a problem, since all the i915 suspend/resume steps that need to be ordered wrt. the HDA driver's suspend/resume steps are separated out to the i915 suspend_late/resume_early hooks. That will change in a follow-up patchset where we'll need this ordering guarantee for steps that are in the i915 suspend/resume hooks (and which can't be moved to suspend_late/resume_early for other reasons). So this patch is a preparation for that follow-up patchset. The change also allows us to move towards removing the i915 suspend_late/resume_early hooks alltogether. Since we only need to ensure the ordering during suspend/resume and not during driver probing create the link with DL_FLAG_STATELESS. Since the probe time ordering has to be optional we use the component framework for that. Similarly for runtime PM we depend on the audio driver getting/putting an i915 runtime PM reference whenever it needs it (along with the proper i915 display power domain) via the audio component ops get_power / put_power hooks. So we create the device link without DL_FLAG_PM_RUNTIME. v2: (Ville) - Add a note to the commit message about not using the device link runtime PM ordering. - Handle the error return from device_link_add().

Few core devices still need to be detected to set legacy quirks. We also add support for booting am335x, am437x and dra7 SoCs with L4 devices defined in device tree instead of legacy platform data. And finally we simplify suspend with just SET_NOIRQ_SYSTEM_SLEEP_PM_OPS and dropping the custom functions that were attempting to work around issues that really turned out to be child device driver related issues. Apologies for a late pull request, debugging the suspend issues took a while and I did not want to send these changes until that got sorted out. commit b3378de0266989bc3215c8c714c8231d5ab27a9f Merge: a35f408eba76b 5284521a290ef Author: Tony Lindgren Date: Thu Oct 18 10:02:45 2018 -0700 Merge remote-tracking branch 'gpio/ib-omap' into omap-for-v4.21/dt-ti-sysc commit a35f408eba76ba82139254e0a2df46291e68885a Merge: 4f1985af21c70 ce32d59ee2cd0 Author: Tony Lindgren Date: Thu Oct 18 09:55:46 2018 -0700 Merge commit 'ce32d59ee2cd036f6e8a6ed17a06a0b0bec5c67c' into omap-for-v4.21/dt-ti-sysc commit 4f1985af21c709eaa6e08580b759f8a4ecb0f5df Merge: 5f681f41fe171 d6e7bbc148f9f Author: Tony Lindgren Date: Thu Oct 18 09:47:50 2018 -0700 Merge commit 'd6e7bbc148f9fbec8a0117b0d0f420c9710e6d81' into omap-for-v4.21/dt-ti-sysc commit 73f522bad1794f7144caff1f46f1ffb31966a386 Author: Ville Syrjälä Date: Tue Oct 16 18:04:13 2018 +0300 drm/i915: Use i915_gem_object_get_dma_address() to populate rotated vmas Replace the kvmalloc_array() with i915_gem_object_get_dma_address() when populating rotated vmas. One random access mechanism ought to be enough for everyone? To calculate the size of the radix tree I think we can do something like this (assuming 64bit pointers): num_pages = obj_size / 4096 tree_height = ceil(log64(num_pages)) num_nodes = sum(64^n, n, 0, tree_height-1) tree_size = num_nodes * 576 If we compare that with the object size we should get a relative overhead of around .2% to 1% for reasonable sized objects, which framebuffers tend to be.

Such timeline syncobjs support the following operations: * CPU query - A host operation that allows querying the payload of the timeline syncobj. * CPU wait - A host operation that allows a blocking wait for a timeline syncobj to reach a specified value. * Device wait - A device operation that allows waiting for a timeline syncobj to reach a specified value. * Device signal - A device operation that allows advancing the timeline syncobj to a specified value. v1: Since it's a timeline, that means the front time point(PT) always is signaled before the late PT. a. signal PT design: Signal PT fence N depends on PT[N-1] fence and signal opertion fence, when PT[N] fence is signaled, the timeline will increase to value of PT[N]. b. wait PT design: Wait PT fence is signaled by reaching timeline point value, when timeline is increasing, will compare wait PTs value with new timeline value, if PT value is lower than timeline value, then wait PT will be signaled, otherwise keep in list. syncobj wait operation can wait on any point of timeline, so need a RB tree to order them. And wait PT could ahead of signal PT, we need a sumission fence to perform that. v2: 1. remove unused DRM_SYNCOBJ_CREATE_TYPE_NORMAL. (Christian) 2. move unexposed denitions to .c file.

This can leave users who expect it to be more like a WARN_ON, just without a warning in non-debug builds, in complete ignorance. Another gotcha with it is that it cannot be used as a statement. Which is again different from a standard kernel WARN_ON. This patch fixes both problems by making it behave as one would expect. It can now be used both as an expression and as statement, and also the condition evaluates properly in all builds - code under the conditional will therefore not unexpectedly disappear. To satisfy call sites which really want the code under the conditional to completely disappear, we add GEM_DEBUG_WARN_ON and convert some of the callers to it. This one can also be used as both expression and statement. >From the above it follows GEM_DEBUG_WARN_ON should be used in situations where we are certain the condition will be hit during development, but at a place in code where error can be handled to the benefit of not crashing the machine. GEM_WARN_ON on the other hand should be used where condition may happen in production and we just want to distinguish the level of debugging output emitted between the production and debug build. v2: * Dropped BUG_ON hunk.

So in order to fix this, while still being careful that we don't break modesets that a driver may perform before being registered with userspace, we replace connector->registered with a tristate member, connector->registration_state. This allows us to keep track of whether or not a connector is still initializing and hasn't been exposed to userspace, is currently registered and exposed to userspace, or has been legitimately removed from the system after having once been present. Using this info, we can prevent userspace from performing new modesets on unregistered connectors while still allowing the driver to perform modesets on unregistered connectors before the driver has finished being registered. Changes since v1: - Fix WARN_ON() in drm_connector_cleanup() that CI caught with this patchset in igt@drv_module_reload@basic-reload-inject and igt@drv_module_reload@basic-reload by checking if the connector is registered instead of unregistered, as calling drm_connector_cleanup() on a connector that hasn't been registered with userspace yet should stay valid. - Remove unregistered_connector_check(), and just go back to what we were doing before in commit 4d80273976bf ("drm/atomic_helper: Disallow new modesets on unregistered connectors") except replacing READ_ONCE(connector->registered) with drm_connector_is_unregistered(). This gets rid of the behavior of allowing DPMS On<->Off, but that should be fine as it's more consistent with the UAPI we had before - danvet - s/drm_connector_unregistered/drm_connector_is_unregistered/ - danvet - Update documentation, fix some typos.

V2: rebase V3: Addressed review comments from Ville - add enum crtc_output_format instead of bool ycbcr420 - use crtc_output_format=4:4:4 for modeset of LSPCON 4:2:0 output cases in this way we will have YCBCR 4:4:4 framework ready (except the ABI part) V4: Added r-b from Maarten (for v3) Addressed review comments from Ville: - Do not add a non-atomic state variable to determine lspcon output.

V5: Addressed review comments from Ville: - Change the state bool name from external scaling to something more relavent. - Keep the info and adjusted_mode structures const. - use crtc_state instead of pipe_config. - Push all the config change into lspcon_ycbcr420_config function.

It is missing the fact that the indexed format is not supported with Yf tiling. It is worth noticing that skl_plane_format_mod_supported() correctly handles for the C8/Yf combination, but this function runs during modeset time, so we only reject the combination later. Ville recently proposed a new IGT test that only uses addfb to assert supported formats, so that IGT was failing. Add the check so we get green squares right from the start after Ville merges his test. Also drive-by fix the missing /* fall through */ in the chunk we modified by just turning it into a "break;" since IMHO breaks are easier to read than fall-throughs.

Since this happens before the driver's registered with userspace, it's connectors are also unregistered and thus-states which would turn on DPMS on a connector end up getting rejected since the connector isn't registered. These bugs managed to get past Intel's CI partially due to the fact it never ran a full test on my patches for some reason, but also because all of the tests unload the GPU once before running. Since this bug is only really triggered when the drivers tries to perform a modeset before it's been fully registered with userspace when coming from whatever display configuration the firmware left us with, it likely would never have been picked up by CI in the first place. After some discussion with vsyrjala, we decided the best course of action would be to just move the unregistered connector checks out of update_connector_routing() and into drm_atomic_set_crtc_for_connector(). The reason for this being that legacy modesetting isn't going to be expecting failures anywhere (at least this is the case with X), so ideally we want to ensure that any DPMS changes will still work even on unregistered connectors. Instead, we now only reject new modesets which would change the current CRTC assigned to an unregistered connector unless no new CRTC is being assigned to replace the connector's previous one.

In case of some panels they advertise higher link rate/lane count than whats required for supporting the panel's native mode. But we always link train at highest link rate/lane count for eDP and if that fails we can still fallback to lower link rate/lane count as long as the fallback link BW still fits the native mode to avoid pruning the panel's native mode yet retraining at fallback values to recover from a blank screen. v3: * Add const for fixed_mode (Ville) v2: * Send uevent if link failure on eDP unconditionally Fixes: c0cfb10d9e1d ("drm/i915/edp: Do not do link training fallback or prune modes on EDP") Cc: Clinton Taylor Cc: Jani Nikula Cc: Ville Syrjala Cc: Daniel Vetter Cc: Lucas De Marchi Cc: # v4.17+ Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=107489 Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=105338 Signed-off-by: Manasi Navare Tested-by: Alexander Wilson Reviewed-by: Ville Syrjälä Link: https://patchwork.freedesktop.org/patch/msgid/20181009212804.702-1-manasi.d.navare@intel.com commit d4b26e4f438f0b070fbcd1e765fb53db9ac59112 Author: Jani Nikula Date: Tue Oct 9 17:11:03 2018 +0300 drm/i915: add a common connector type independent destroy hook Almost all of the connector destroy functions do the same thing.

Currently this is impossible when the port has disappeared, since the VCPI slot searching we try to do in intel_dp_mst_compute_config() will fail with -EINVAL. Since the only commits we want to allow on no-longer-present MST ports are ones that shut off display hardware, we already know that no VCPI allocations are needed. So, hardcode the VCPI slot count to 0 when intel_dp_mst_compute_config() is called on an MST port that's gone.

That is not entirely great as it means the sprite enable may actually happen one frame after we've already signalled flip completion. At the very least crc checks may fail due to the sprite not yet being visible when we expect it. We already have code to deal with big FIFO mode when it comes to the sprite scaling on IVB (WaCxSRDisabledForSpriteScaling:ivb). Let's extend that workaround to kick in whenever the sprite is in the process of being enabled. Also ILK/SNB bspec has some notes to indicate that we should most likely also do the sprite scaling w/a on all three platforms, so let's do that as well. Pretty easy to reproduce on SNB/IVB.

However we are passing around the crtc we think that the plane is supposed to be using rather than the crtc it is currently using. That doesn't work all that well because we may have to do vblank waits etc. and the other pipe might not even be enabled here. So let's pass the plane's current crtc to intel_plane_disable_noatomic() so that it can its job correctly. To do that semi-cleanly we also have to change the plane readout to record the plane's visibility into the bitmasks of the crtc where the plane is currently enabled rather than to the crtc we want to use for the plane. One caveat here is that our active_planes bitmask will get confused if both planes are enabled on the same pipe.

Add plane alpha blending support with the different blend modes. This has been tested on a icl to show the correct results, on earlier platforms small rounding errors cause issues. But this already happens case with fully transparant or fully opaque RGB8888 fb's. The recommended HW workaround is to disable alpha blending when the plane alpha is 0 (transparant, hide plane) or 0xff (opaque, disable blending). This is easy to implement on any platform, so just do that. The tests for userspace are also available, and pass on gen11.

These flows are likely to correspond with short, interactive tasks and so be more latency sensitive than the longer free running queues. As soon as the client has more than one request in the queue, further requests are not boosted and it settles down into ordinary steady state behaviour. Such small kicks dramatically help combat the starvation issue, by allowing each client the opportunity to run even when the system is under heavy throughput load (within the constraints of the user selected priority). v2: Mark the preempted request as the start of a new flow, to prevent a single client being continually gazumped by its peers.

With eDP 1.4 rate select method and DSC features, this is decreasingly the case. There's a need to optimize the link parameters. Moreover, already eDP 1.3 states fast link with fewer lanes is preferred over the wide and slow. (Wide and slow should still be more reliable for longer cable lengths.) Additionally, there have been reports of panels failing on arbitrary link configurations, although arguably all configurations they claim to support should work. Optimize eDP 1.4+ link config fast and narrow. Side note: The implementation has a near duplicate of the link config function, with just the two inner for loops turned inside out. Perhaps there'd be a way to make this, say, more table driven to reduce the duplication, but seems like that would lead to duplication in the table generation. We'll also have to see how the link config optimization for DSC turns out.

And let's do it in a nicer form than what we had before and do it for all plane types (easy now that we have the ->max_stride() plane vfunc).

This will only disable planes we actually had marked as visible in crtc_state->visible_planes and cleans up intel_crtc_disable_plane() slightly.

We need to assume the plane has been visible before, even if no CRTC is assigned to the plane. This is because when enabling a nv12 plane on gen11, we will have to enable an extra plane and make it visible by marking it in crtc_state->active_planes for intel_update_planes_on_crtc(). Additionally, clear visible flag in intel_plane_atomic_check, in case we ever hit a bug with visibility. Our code implicitly assumes that plane_state->visible is only true when crtc and fb are set, so we will either null deref in intel_fbc_choose_crtc() or do something bad during the actual commit which cares even more. Changes since v1: - Unconditionally clear crtc_state->active_planes as well. - Reword commit message, since this is now a preparation patch for NV12 Y / UV plane linking.
