The driver was added in 2003 and there's no evidence that it has any recent user, all changes seem to be tree-wide, subsystem-wide, or the result of static code analysis.

Convert all platform drivers below drivers/watchdog/ to use .remove(), with the eventual goal to drop struct platform_driver::remove_new(). As .remove() and .remove_new() have the same prototypes, conversion is done by just changing the structure member name in the driver initializer.

In this case, the watchdog device need to be powered on in struct watchdog_ops::restart API. This can be done though pm_runtime_resume_and_get() API if the watchdog PM domain and watchdog device are marked as IRQ safe. We mark the watchdog PM domain as IRQ safe with GENPD_FLAG_IRQ_SAFE when the watchdog PM domain is registered and the watchdog device though pm_runtime_irq_safe(). Before commit e4cf89596c1f ("watchdog: rzg2l_wdt: Fix 'BUG: Invalid wait context'") pm_runtime_get_sync() was used in watchdog restart handler (which is similar to pm_runtime_resume_and_get() except the later one handles the runtime resume errors). Commit e4cf89596c1f ("watchdog: rzg2l_wdt: Fix 'BUG: Invalid wait context'") dropped the pm_runtime_get_sync() and replaced it with clk_prepare_enable() to avoid invalid wait context due to genpd_lock() in genpd_runtime_resume() being called from atomic context. But clk_prepare_enable() doesn't fit for this either (as reported by Ulf Hansson) as clk_prepare() can also sleep (it just not throw invalid wait context warning as it is not written for this). Because the watchdog device is marked now as IRQ safe (though this patch) the irq_safe_dev_in_sleep_domain() call from genpd_runtime_resume() returns 1 for devices not registering an IRQ safe PM domain for watchdog (as the watchdog device is IRQ safe, PM domain is not and watchdog PM domain is always-on), this being the case for RZ/G3S with old device trees and the rest of the SoCs that use this driver, we can now drop also the clk_prepare_enable() calls in restart handler and rely on pm_runtime_resume_and_get(). Thus, drop clk_prepare_enable() and use pm_runtime_resume_and_get() in watchdog restart handler.

Proposed advantage of this would be readability but one concern Christian raised was that there could be many fences, that they are typically mostly sorted, and so the kernel's heap sort would be much worse by the proposed algorithm.

N Before After 0 1 2-3 100% 0% (Ie. all resolved to a single fence) 4-5 6-9 10+ In the case of vkcube all invocations in the 2-3 bucket were actually just two input fences. From these numbers it looks like the heap sort should not be a disadvantage, given how the dominant case is <= 2 input fences which heap sort solves with just one compare and swap. (And for the case of one input fence we have a fast path in the previous patch.) A complementary possibility is to implement a different sorting algorithm under the same API as the kernel's sort() and so keep the simplicity, potentially moving the new sort under lib/ if it would be found more widely useful. v2: * Hold on to fence references and reduce commentary. (Christian) * Record and use latest signaled timestamp in the 2nd loop too. * Consolidate zero or one fences fast paths. v3: * Reverse the seqno sort order for a simpler squashing pass.

charset=UTF-8 Content-Transfer-Encoding: 8bit After commit 0edb555a65d1 ("platform: Make platform_driver::remove() return void") .remove() is (again) the right callback to implement for platform drivers. Convert all platform drivers below drivers/ufs to use .remove(), with the eventual goal to drop struct platform_driver::remove_new(). As .remove() and .remove_new() have the same prototypes, conversion is done by just changing the structure member name in the driver initializer.

The current UFS BSG code calls ufshcd_send_uic_cmd() directly, with which the second interrupt, i.e., UIC Power Mode interrupt, shall be treated as unhandled interrupt. In addition, after the UIC command is completed, user layer application has to poll UniPro and/or M-PHY state machine to confirm the power mode change is finished. Add a new wrapper function ufshcd_send_bsg_uic_cmd() and call it from ufs_bsg_request() so that if a UIC SET command is targeting the PA_PWRMODE attribute it can be redirected to ufshcd_uic_pwr_ctrl().

The current sb write validation implementation returns -EFSCORRUPTED for unknown compat features, preventing filesystem write operations and contradicting the feature's definition. Additionally, if the mounted image is unclean, the log recovery may need to write to the superblock. Returning an error for unknown compat features during sb write validation can cause mount failures. Although XFS currently does not use compat feature flags, this issue affects current kernels' ability to mount images that may use compat feature flags in the future. Since superblock read validation already warns about unknown compat features, it's unnecessary to repeat this warning during write validation. Therefore, the relevant code in write validation is being removed.

Unfortunately, when setting the max_agbno limit for the inode chunk allocation, we do not take this into account. This means we can allocate a sparse inode chunk that overlaps beyond the end of an AG. When we go to allocate an inode from that sparse chunk, the irec fails validation because the agbno of the start of the irec is beyond valid limits for the runt AG. Prevent this from happening by taking into account the size of the runt AG when allocating inode chunks.

Hence when the quota report runs, we have 300 blocks of delalloc data on an inode, with a soft limit of 200 blocks. XFS dquots account delalloc reservations as used space, hence the dquot is over the soft limit. However, we don't update the soft limit timers until we do a transactional update of the dquot. That is, the dquot sits over the soft limit without a softlimit timer being started until writeback occurs and the allocation modifies the dquot and we call xfs_qm_adjust_dqtimers() from xfs_trans_apply_dquot_deltas() in xfs_trans_commit() context. This isn't really a problem, except for this debug code in xfs_qm_scall_getquota_fill_qc(): if (xfs_dquot_is_enforced(dqp) && dqp->q_id != 0) { if ((dst->d_space > dst->d_spc_softlimit) && (dst->d_spc_softlimit > 0)) { ASSERT(dst->d_spc_timer != 0); } .... It asserts taht if the used block count is over the soft limit, it *must* have a soft limit timer running. This is clearly not the case, because we haven't committed the delalloc space to disk yet. Hence the soft limit is only exceeded temporarily in memory (which isn't an issue) and we start the timer the moment we exceed the soft limit in journalled metadata. This debug was introduced in: commit 0d5ad8383061fbc0a9804fbb98218750000fe032 Author: Supriya Wickrematillake Date: Wed May 15 22:44:44 1996 +0000 initial checkin quotactl syscall functions. The very first quota support commit back in 1996. This is zero-day debug for Irix and, as it turns out, a zero-day bug in the debug code because the delalloc code on Irix didn't update the softlimit timers, either. IOWs, this issue has been in the code for 28 years. We obviously don't care if soft limit timers are a bit rubbery when we have delalloc reservations in memory. Production systems running quota reports have been exposed to this situation for 28 years and nobody has noticed it, so the debug code is essentially worthless at this point in time. We also have the on-disk dquot verifiers checking that the soft limit timer is running whenever the dquot is over the soft limit before we write it to disk and after we read it from disk. These aren't firing, so it is clear the issue is purely a temporary in-memory incoherency that I never would have noticed had the test not silently failed to unmount the filesystem. Hence I'm simply going to trash this runtime debug because it isn't useful in the slightest for catching quota bugs. Signed-off-by: Dave Chinner Reviewed-by: Darrick J.

It is waiting for the CIL to flush as part of the log force. The CIL flush is blocked doing shutdown processing of all it's objects, trying to unpin a buffer item. That requires taking the buffer lock.... For the CIL to be doing shutdown processing, the log must be marked with XLOG_IO_ERROR, but that doesn't happen until after the log force is issued. Hence for xfs_do_force_shutdown() to be forcing the log on a shut down log, we must have had a racing xlog_force_shutdown and xfs_force_shutdown like so: p0 p1 CIL push xlog_force_shutdown xfs_log_force test_and_set_bit(XLOG_IO_ERROR) xlog_state_release_iclog() sees XLOG_IO_ERROR xlog_state_shutdown_callbacks .... xfs_buf_item_unpin xfs_buf_lock xfs_force_shutdown xfs_set_shutdown(mp) wins xlog_force_shutdown xfs_log_force xfs_set_shutdown(mp) fails The deadlock can be mitigated by avoiding the log force on the second pass through xlog_force_shutdown. Do this by adding another atomic state bit (XLOG_OP_PENDING_SHUTDOWN) that is set on entry to xlog_force_shutdown() but doesn't mark the log as shutdown.

This made the handler for the interrupt-parent property redundant. In fact, creating device links based solely on interrupt-parent is problematic, because it can create spurious cycles. A node may have this property without itself being an interrupt controller or consumer. For example, this property is often present in the root node or a /soc bus node to set the default interrupt parent for child nodes. However, it is incorrect for the bus to depend on the interrupt controller, as some of the bus's children may not be interrupt consumers at all or may have a different interrupt parent. Resolving these spurious dependency cycles can cause an incorrect probe order for interrupt controller drivers. This was observed on a RISC-V system with both an APLIC and IMSIC under /soc, where interrupt-parent in /soc points to the APLIC, and the APLIC msi-parent points to the IMSIC. fw_devlink found three dependency cycles and attempted to probe the APLIC before the IMSIC. After applying this patch, there were no dependency cycles and the probe order was correct.

Fix is simple as changing the type from int to u32, however, when compared to XSKMAP case, one more thing needs to be addressed. When map is released from system via dev_map_free(), we iterate through all of the entries and an iterator variable is also an int, which implies OOB accesses. Again, change it to be u32.

However, the pool also keeps the copies of DMA-related information that are initialized in the same way in xp_init_dma_info(), but cleared by xp_dma_unmap() only for the last remaining pool, this causes the problems below. The first one is that the commit adbf5a42341f ("ice: remove af_xdp_zc_qps bitmap") relies on pool->dev to determine the presence of a ZC pool on a given queue, avoiding internal bookkeeping. This works perfectly fine if the UMEM is not shared, but reliably fails otherwise as stated in the linked report. The second one is pool->dma_pages which is dynamically allocated and only freed in xp_dma_unmap(), this leads to a small memory leak. kmemleak does not catch it, but by printing the allocation results after terminating the userspace program it is possible to see that all addresses except the one belonging to the last detached pool are still accessible through the kmemleak dump functionality. Always clear the DMA mapping information from the pool and free pool->dma_pages when unmapping the pool, so that the only difference between results of the last remaining user's call and the ones before would be the destruction of the DMA mapping.

It was found that USB stack of Zephyr RTOS overwrites USB EP addresses, if they have different last 4 bytes in absence of other endpoints. For example in case of gs_usb candlelight firmware EP-IN is 0x81 and EP-OUT 0x02. If there are no additional USB endpoints, Zephyr RTOS will overwrite EP-OUT to 0x01. More information can be found in the discussion with Zephyr RTOS USB stack maintainer here: https://github.com/zephyrproject-rtos/zephyr/issues/67812 There are already two different gs_usb FW driver implementations based on Zephyr RTOS: 1. https://github.com/CANnectivity/cannectivity (by: https://github.com/henrikbrixandersen) 2. https://github.com/zephyrproject-rtos/zephyr/compare/main...KozhinovAlexander:zephyr:gs_usb (by: https://github.com/KozhinovAlexander) At the moment both Zephyr RTOS implementations use dummy USB endpoint, to overcome described USB stack behavior from Zephyr itself. Since Zephyr RTOS is intended to be used on microcontrollers with very constrained amount of resources (ROM, RAM) and additional endpoint requires memory, it is more convenient to update the gs_usb driver in the Linux kernel. To fix this problem, update the gs_usb driver from using hard coded endpoint numbers to evaluate the endpoint descriptors and use the endpoints provided there.

Commit b8e0ddd36ce9 ("can: mcp251xfd: tef: prepare to workaround broken TEF FIFO tail index erratum") introduced mcp251xfd_get_tef_len() to get the number of unhandled transmit events from the Transmit Event FIFO (TEF). As the TEF has no head index, the driver uses the TX-FIFO's tail index instead, assuming that send frames are completed. When calculating the number of unhandled TEF events, that commit didn't take mcp2518fd erratum DS80000789E 6. into account. According to that erratum, the FIFOCI bits of a FIFOSTA register, here the TX-FIFO tail index might be corrupted. However here it seems the bit indicating that the TX-FIFO is empty (MCP251XFD_REG_FIFOSTA_TFERFFIF) is not correct while the TX-FIFO tail index is. Assume that the TX-FIFO is indeed empty if: - Chip's head and tail index are equal (len == 0). - The TX-FIFO is less than half full. (The TX-FIFO empty case has already been checked at the beginning of this function.) - No free buffers in the TX ring. If the TX-FIFO is assumed to be empty, assume that the TEF is full and return the number of elements in the TX-FIFO (which equals the number of TEF elements). If these assumptions are false, the driver might read to many objects from the TEF. mcp251xfd_handle_tefif_one() checks the sequence numbers and will refuse to process old events.

In this specific case, the current behaviour is to zero out the entire specifier so that the translation could be carried on as an offset from zero. This includes address specifier that has flags (e.g. PCI ranges). Once the flags portion has been zeroed, the translation chain is broken since the mapping functions will check the upcoming address specifier against mismatching flags, always failing the 1:1 mapping and its entire purpose of always succeeding.

This made at least one Weida device (2575:0910 in an ASUS Vivobook S14) very unhappy, as the bus probe despite being successful somehow lead to the following power command failing so hard that the device never lets go of the bus. This means that even retries of the power command would fail on a timeout as the bus remains busy. Remove the bus probe on resume and instead reintroduce retry of the power command for wake-up purposes while respecting the newly established wake-up retry timings.

This same issue has been reported by the Intel kernel test robot previously. Digging deeper into both LLVM and the kernel code reveals this to be a undefined behavior problem. ip_vs_protocol_init() uses a on-stack buffer of 64 chars to store the registered protocol names and leaves it uninitialized after definition. The function calls strnlen() when concatenating protocol names into the buffer. With CONFIG_FORTIFY_SOURCE strnlen() performs an extra step to check whether the last byte of the input char buffer is a null character (commit 3009f891bb9f ("fortify: Allow strlen() and strnlen() to pass compile-time known lengths")). This, together with possibly other configurations, cause the following IR to be generated: define hidden i32 @ip_vs_protocol_init() local_unnamed_addr #5 section ".init.text" align 16 !kcfi_type !29 { %1 = alloca [64 x i8], align 16 ... 14: ; preds = %11 %15 = getelementptr inbounds i8, ptr %1, i64 63 %16 = load i8, ptr %15, align 1 %17 = tail call i1 @llvm.is.constant.i8(i8 %16) %18 = icmp eq i8 %16, 0 %19 = select i1 %17, i1 %18, i1 false br i1 %19, label %20, label %23 20: ; preds = %14 %21 = call i64 @strlen(ptr noundef nonnull dereferenceable(1) %1) #23 ... 23: ; preds = %14, %11, %20 %24 = call i64 @strnlen(ptr noundef nonnull dereferenceable(1) %1, i64 noundef 64) #24 ... } The above code calculates the address of the last char in the buffer (value %15) and then loads from it (value %16). Because the buffer is never initialized, the LLVM GVN pass marks value %16 as undefined: %13 = getelementptr inbounds i8, ptr %1, i64 63 br i1 undef, label %14, label %17 This gives later passes (SCCP, in particular) more DCE opportunities by propagating the undef value further, and eventually removes everything after the load on the uninitialized stack location: define hidden i32 @ip_vs_protocol_init() local_unnamed_addr #0 section ".init.text" align 16 !kcfi_type !11 { %1 = alloca [64 x i8], align 16 ... 12: ; preds = %11 %13 = getelementptr inbounds i8, ptr %1, i64 63 unreachable } In this way, the generated native code will just fall through to the next function, as LLVM does not generate any code for the unreachable IR instruction and leaves the function without a terminator. Zero the on-stack buffer to avoid this possible UB.

Commit 4ff47df40447 ("btrfs: move priv off stack in btrfs_encoded_read_regular_fill_pages()") moved 'struct btrfs_encoded_read_private' off the stack. Before that commit one can see a corruption of the private data when analyzing the vmcore after a crash: *(struct btrfs_encoded_read_private *)0xffff88815626eec8 = { .wait = (wait_queue_head_t){ .lock = (spinlock_t){ .rlock = (struct raw_spinlock){ .raw_lock = (arch_spinlock_t){ .val = (atomic_t){ .counter = (int)-2005885696, }, .locked = (u8)0, .pending = (u8)157, .locked_pending = (u16)40192, .tail = (u16)34928, }, .magic = (unsigned int)536325682, .owner_cpu = (unsigned int)29, .owner = (void *)__SCT__tp_func_btrfs_transaction_commit+0x0 = 0x0, .dep_map = (struct lockdep_map){ .key = (struct lock_class_key *)0xffff8881575a3b6c, .class_cache = (struct lock_class *[2]){ 0xffff8882a71985c0, 0xffffea00066f5d40 }, .name = (const char *)0xffff88815626f100 = "", .wait_type_outer = (u8)37, .wait_type_inner = (u8)178, .lock_type = (u8)154, }, }, .__padding = (u8 [24]){ 0, 157, 112, 136, 50, 174, 247, 31, 29 }, .dep_map = (struct lockdep_map){ .key = (struct lock_class_key *)0xffff8881575a3b6c, .class_cache = (struct lock_class *[2]){ 0xffff8882a71985c0, 0xffffea00066f5d40 }, .name = (const char *)0xffff88815626f100 = "", .wait_type_outer = (u8)37, .wait_type_inner = (u8)178, .lock_type = (u8)154, }, }, .head = (struct list_head){ .next = (struct list_head *)0x112cca, .prev = (struct list_head *)0x47, }, }, .pending = (atomic_t){ .counter = (int)-1491499288, }, .status = (blk_status_t)130, } Here we can see several indicators of in-memory data corruption, e.g. the large negative atomic values of ->pending or ->wait->lock->rlock->raw_lock->val, as well as the bogus spinlock magic 0x1ff7ae32 (decimal 536325682 above) instead of 0xdead4ead or the bogus pointer values for ->wait->head. To fix this, change atomic_dec_return() to atomic_dec_and_test() to fix the corruption, as atomic_dec_return() is defined as two instructions on x86_64, whereas atomic_dec_and_test() is defined as a single atomic operation. This can lead to a situation where counter value is already decremented but the if statement in btrfs_encoded_read_endio() is not completely processed, i.e. the 0 test has not completed. If another thread continues executing btrfs_encoded_read_regular_fill_pages() the atomic_dec_return() there can see an already updated ->pending counter and continues by freeing the private data. Continuing in the endio handler the test for 0 succeeds and the wait_queue is woken up, resulting in a use-after-free.

And while it's waiting for the transaction to complete, it's holding an extent range locked in the same inode that task B is operating, which causes a deadlock between these 3 tasks. The extent range for the inode was locked at the start of the fiemap operation, early at extent_fiemap(). In short these tasks deadlock because: 1) Task A is waiting for task B to release its transaction handle; 2) Task B is waiting to lock an extent range for an inode while holding a transaction handle open; 3) Task C is waiting for the current transaction to complete (for task A to finish the transaction commit) while holding the extent range for the inode locked, so task B can't progress and release its transaction handle. This results in an ABBA deadlock involving transaction commits and extent locks. Extent locks are higher level locks, like inode VFS locks, and should always be acquired before joining or starting a transaction, but recently commit 2206265f41e9 ("btrfs: remove code duplication in ordered extent finishing") accidentally changed btrfs_finish_one_ordered() to do the transaction join before locking the extent range. Fix this by making sure that btrfs_finish_one_ordered() always locks the extent before joining a transaction and add an explicit comment about the need for this order.

The difference is, however, that no packet will be handled any longer after all queued packets are handled but no enough data is fed. In the case of implicit feedback mode, the capture-side packet handling triggers the re-queuing, and this checks the XRUN. OTOH, in the low-latency mode, it just stops without XRUN notification unless any new action is taken from user-space via ack callback. For example, when you stop the stream in aplay, no XRUN is reported. This patch adds the XRUN check at the packet complete callback in the case all pending URBs are exhausted. Strictly speaking, this state doesn't match really with XRUN; in theory the application may queue immediately after this happens. But such behavior is only for 1-period configuration, which the USB-audio driver doesn't support. So we may conclude that this situation leads certainly to XRUN. A caveat is that the XRUN should be triggered only for the PCM RUNNING state, and not during DRAINING. This additional state check is put in notify_xrun(), too.

Meanwhile, some of its code are written as if the buffer is on iomem and use the special helpers for the iomem (e.g. copy_from_iter_toio() or memset_io()). Those are rather useless and the standard helpers should be used. Similarly, the PCM mmap callback is set to a special one with snd_pcm_lib_mmap_iomem, but this is also nonsense, because SH architecture doesn't support this function, hence it leads just to NULL -- the fallback to the standard helper. This patch replaces those special setups with the standard ones.

Here, a bootstrap build is a build host variant of a target. E.g., assume that you're performing a bpftool cross-build on x86 to riscv, a bootstrap build would then be an x86 variant of bpftool. The typical way to perform the host build variant, is to pass "ARCH=" in a sub-make. However, if a variable has been set with a command argument, then ordinary assignments in the makefile are ignored. This side-effect results in that ARCH, and variables depending on ARCH are not set. Workaround by overriding ARCH to the host arch, if ARCH is empty.

Whenever this function is used to enqueue SKBs, the backlog statistic of the tbf is not increased correctly. This can lead to underflows of the 'backlog' byte-statistic value when these packets are dequeued from tbf. Reproduce the bug: Ensure that the sender machine has GSO enabled. Configured the tbf on the outgoing interface of the machine as follows (burstsize = 1 MTU): $ tc qdisc add dev root handle 1: tbf rate 50Mbit burst 1514 latency 50ms Send bulk TCP traffic out via this interface, e.g., by running an iPerf3 client on this machine. Check the qdisc statistics: $ tc -s qdisc show dev The 'backlog' byte-statistic has incorrect values while traffic is transferred, e.g., high values due to u32 underflows. When the transfer is stopped, the value is != 0, which should never happen. This patch fixes this bug by updating the statistics correctly, even if single SKBs of a GSO SKB cannot be enqueued.

Just get rid of the 'remove_new' member function, which is just an alias for the plain 'remove', and had a comment to that effect: /* * .remove_new() is a relic from a prototype conversion of .remove(). * New drivers are supposed to implement .remove(). Once all drivers are * converted to not use .remove_new any more, it will be dropped. */ This was just a tree-wide 'sed' script that replaced '.remove_new' with '.remove', with some care taken to turn a subsequent tab into two tabs to make things line up. I did do some minimal manual whitespace adjustment for places that used spaces to line things up. Then I just removed the old (sic) .remove_new member function, and this is the end result. No more unnecessary conversion noise.

Since do_softirq_post_smp_call_flush() is called with preempt disabled, raising a SOFTIRQ during flush_smp_call_function_queue() can lead to longer preempt disabled sections. Since commit b2a02fc43a1f ("smp: Optimize send_call_function_single_ipi()") IPIs to an idle CPU in TIF_POLLING_NRFLAG mode can be optimized out by instead setting TIF_NEED_RESCHED bit in idle task's thread_info and relying on the flush_smp_call_function_queue() in the idle-exit path to run the SMP-call-function. To trigger an idle load balancing, the scheduler queues nohz_csd_function() responsible for triggering an idle load balancing on a target nohz idle CPU and sends an IPI. Only now, this IPI is optimized out and the SMP-call-function is executed from flush_smp_call_function_queue() in do_idle() which can raise a SCHED_SOFTIRQ to trigger the balancing. So far, this went undetected since, the need_resched() check in nohz_csd_function() would make it bail out of idle load balancing early as the idle thread does not clear TIF_POLLING_NRFLAG before calling flush_smp_call_function_queue(). The need_resched() check was added with the intent to catch a new task wakeup, however, it has recently discovered to be unnecessary and will be removed in the subsequent commit after which nohz_csd_function() can raise a SCHED_SOFTIRQ from flush_smp_call_function_queue() to trigger an idle load balance on an idle target in TIF_POLLING_NRFLAG mode. nohz_csd_function() bails out early if "idle_cpu()" check for the target CPU, and does not lock the target CPU's rq until the very end, once it has found tasks to run on the CPU and will not inhibit the wakeup of, or running of a newly woken up higher priority task. Account for this and prevent a WARN_ON_ONCE() when SCHED_SOFTIRQ is raised from flush_smp_call_function_queue().

To justify this removal, consider all the following case where an idle load balancing could race with a task wakeup: o Since commit f3dd3f674555b ("sched: Remove the limitation of WF_ON_CPU on wakelist if wakee cpu is idle") a target perceived to be idle (target_rq->nr_running == 0) will return true for ttwu_queue_cond(target) which will offload the task wakeup to the idle target via an IPI. In all such cases target_rq->ttwu_pending will be set to 1 before queuing the wake function. If an idle load balance races here, following scenarios are possible: - The CPU is not in TIF_POLLING_NRFLAG mode in which case an actual IPI is sent to the CPU to wake it out of idle. If the nohz_csd_func() queues before sched_ttwu_pending(), the idle load balance will bail out since idle_cpu(target) returns 0 since target_rq->ttwu_pending is 1. If the nohz_csd_func() is queued after sched_ttwu_pending() it should see rq->nr_running to be non-zero and bail out of idle load balancing. - The CPU is in TIF_POLLING_NRFLAG mode and instead of an actual IPI, the sender will simply set TIF_NEED_RESCHED for the target to put it out of idle and flush_smp_call_function_queue() in do_idle() will execute the call function. Depending on the ordering of the queuing of nohz_csd_func() and sched_ttwu_pending(), the idle_cpu() check in nohz_csd_func() should either see target_rq->ttwu_pending = 1 or target_rq->nr_running to be non-zero if there is a genuine task wakeup racing with the idle load balance kick. o The waker CPU perceives the target CPU to be busy (targer_rq->nr_running != 0) but the CPU is in fact going idle and due to a series of unfortunate events, the system reaches a case where the waker CPU decides to perform the wakeup by itself in ttwu_queue() on the target CPU but target is concurrently selected for idle load balance (XXX: Can this happen? I'm not sure, but we'll consider the mother of all coincidences to estimate the worst case scenario). ttwu_do_activate() calls enqueue_task() which would increment "rq->nr_running" post which it calls wakeup_preempt() which is responsible for setting TIF_NEED_RESCHED (via a resched IPI or by setting TIF_NEED_RESCHED on a TIF_POLLING_NRFLAG idle CPU) The key thing to note in this case is that rq->nr_running is already non-zero in case of a wakeup before TIF_NEED_RESCHED is set which would lead to idle_cpu() check returning false. In all cases, it seems that need_resched() check is unnecessary when checking for idle_cpu() first since an impending wakeup racing with idle load balancer will either set the "rq->ttwu_pending" or indicate a newly woken task via "rq->nr_running". Chasing the reason why this check might have existed in the first place, I came across Peter's suggestion on the fist iteration of Suresh's patch from 2011 [1] where the condition to raise the SCHED_SOFTIRQ was: sched_ttwu_do_pending(list); if (unlikely((rq->idle == current) && rq->nohz_balance_kick && !need_resched())) raise_softirq_irqoff(SCHED_SOFTIRQ); Since the condition to raise the SCHED_SOFIRQ was preceded by sched_ttwu_do_pending() (which is equivalent of sched_ttwu_pending()) in the current upstream kernel, the need_resched() check was necessary to catch a newly queued task. Peter suggested modifying it to: if (idle_cpu() && rq->nohz_balance_kick && !need_resched()) raise_softirq_irqoff(SCHED_SOFTIRQ); where idle_cpu() seems to have replaced "rq->idle == current" check. Even back then, the idle_cpu() check would have been sufficient to catch a new task being enqueued. Since commit b2a02fc43a1f ("smp: Optimize send_call_function_single_ipi()") overloads the interpretation of TIF_NEED_RESCHED for TIF_POLLING_NRFLAG idling, remove the need_resched() check in nohz_csd_func() to raise SCHED_SOFTIRQ based on Peter's suggestion.

A softirq raised by the call-function is handled shortly after in do_softirq_post_smp_call_flush() but the TIF_NEED_RESCHED flag remains set and is only cleared later when schedule_idle() calls __schedule(). need_resched() check in _nohz_idle_balance() exists to bail out of load balancing if another task has woken up on the CPU currently in-charge of idle load balancing which is being processed in SCHED_SOFTIRQ context. Since the optimization mentioned above overloads the interpretation of TIF_NEED_RESCHED, check for idle_cpu() before going with the existing need_resched() check which can catch a genuine task wakeup on an idle CPU processing SCHED_SOFTIRQ from do_softirq_post_smp_call_flush(), as well as the case where ksoftirqd needs to be preempted as a result of new task wakeup or slice expiry. In case of PREEMPT_RT or threadirqs, although the idle load balancing may be inhibited in some cases on the ilb CPU, the fact that ksoftirqd is the only fair task going back to sleep will trigger a newidle balance on the CPU which will alleviate some imbalance if it exists if idle balance fails to do so.

I was able to easily repoduce this with PREEMPT_RT and managed to isolate down that through various call stacks we were actually calling wake_up_q() twice on the same wake_q. I found that in the problematic commit, I had added the wake_up_q() call in task_blocks_on_rt_mutex() around __ww_mutex_add_waiter(), following a similar pattern in __mutex_lock_common(). However, its just wrong. We haven't dropped the lock->wait_lock, so its contrary to the point of the original patch. And it didn't match the __mutex_lock_common() logic of re-initializing the wake_q after calling it midway in the stack. Looking at it now, the wake_up_q() call is incorrect and should just be removed. So drop the erronious logic I had added.

More precisely, beyond the point when the mmc_bus->shutdown() has been called, to gracefully power off the card, we need to prevent card detect. Otherwise the mmc_rescan work may poll for the card with a CMD13, to see if it's still alive, which then will fail and hang as the card has already been powered off. To fix this problem, let's disable mmc_rescan prior to power off the card during shutdown.

This device-tree root empty node does not have the #address-cells and the #size-cells properties This leads to the use of the default address cells and size cells values which are defined in the code to 1 for the address cells value and 1 for the size cells value. According to the devicetree specification and the OpenFirmware standard (IEEE 1275-1994) the default value for #address-cells should be 2. Also, according to the devicetree specification, the #address-cells and the #size-cells are required properties in the root node. The device tree compiler already uses 2 as default value for address cells and 1 for size cells. The powerpc PROM code also uses 2 as default value for address cells and 1 for size cells. Modern implementation should have the #address-cells and the #size-cells properties set and should not rely on default values. On x86, this root empty node is used and the code default values are used. In preparation of the support for device-tree overlay on PCI devices feature on x86 (i.e. the creation of the PCI root bus device-tree node), the default value for #address-cells needs to be updated. Indeed, on x86_64, addresses are on 64bits and the upper part of an address is needed for correct address translations. On x86_32 having the default value updated does not lead to issues while the upper part of a 64-bit value is zero. Changing the default value for all architectures may break device-tree compatibility. Indeed, existing dts file without the #address-cells property set in the root node will not be compatible with this modification. Instead of updating default values, add both required #address-cells and #size-cells properties in the device-tree empty node. Use 2 for both properties value in order to fully support 64-bit addresses and sizes on systems using this empty root node.

Even though the controller supported only a single master the dw_dma_acpi_filter() method hard-coded two master interfaces with IDs 0 and 1. As a result the sanity check implemented in the commit b336268dde75 ("dmaengine: dw: Add peripheral bus width verification") got incorrect interface data width and thus prevented the client drivers from configuring the DMA-channel with the EINVAL error returned. E.g., the next error was printed for the PXA2xx SPI controller driver trying to configure the requested channels: > [ 164.525604] pxa2xx_spi_pci 0000:00:07.1: DMA slave config failed > [ 164.536105] pxa2xx_spi_pci 0000:00:07.1: failed to get DMA TX descriptor > [ 164.543213] spidev spi-SPT0001:00: SPI transfer failed: -16 The problem would have been spotted much earlier if the iDMA 32-bit controller supported more than one master interfaces. But since it supports just a single master and the iDMA 32-bit specific code just ignores the master IDs in the CTLLO preparation method, the issue has been gone unnoticed so far. Fix the problem by specifying the default master ID for both memory and peripheral devices in the driver data. Thus the issue noticed for the iDMA 32-bit controllers will be eliminated and the ACPI-probed DW DMA controllers will be configured with the correct master ID by default.

As other identify implemenations uses kzalloc for allocating a zero filled buffer, we decided use kzalloc for allocating a zero filled buffer in nvme_execute_identify_ns_nvm function and then use this buffer for copying all zeros to SG list buffers. So esentially, we now avoid using ZERO_PAGE.

It turns out that there versions of these old Intel SSDs that have DSM support disabled in the firmware, which will now lead to errors everytime a Write Zeroes command is issued. Fix this by checking for DSM support before applying the quirk.

The write_buildid() writes the fixed length event first and then variable length filename. But a recent change made it write more data in the padding area accidentally. So readers of the event see zero-filled data for the next entry and treat it incorrectly. This resulted in wrong kernel symbols because the kernel DSO loaded a random vmlinux image in the path as it didn't have a valid build-id.

This means that if XSAVE writes XSTATE_BV[PKRU]=0 then XRSTOR will ignore the value that update_pkru_in_sigframe() writes to the XSAVE buffer. XSTATE_BV[PKRU] only gets written as 0 if PKRU is in its init state. On Intel CPUs, basically never happens because the kernel usually overwrites the init value (aside: this is why we didn't notice this bug until now). But on AMD, the init tracker is more aggressive and will track PKRU as being in its init state upon any wrpkru(0x0). Unfortunately, sig_prepare_pkru() does just that: wrpkru(0x0). This writes XSTATE_BV[PKRU]=0 which makes XRSTOR ignore the PKRU value in the sigframe. To fix this, always overwrite the sigframe XSTATE_BV with a value that has XSTATE_BV[PKRU]==1. This ensures that XRSTOR will not ignore what update_pkru_in_sigframe() wrote. The problematic sequence of events is something like this: Userspace does: * wrpkru(0xffff0000) (or whatever) * Hardware sets: XINUSE[PKRU]=1 Signal happens, kernel is entered: * sig_prepare_pkru() => wrpkru(0x00000000) * Hardware sets: XINUSE[PKRU]=0 (aggressive AMD init tracker) * XSAVE writes most of XSAVE buffer, including XSTATE_BV[PKRU]=XINUSE[PKRU]=0 * update_pkru_in_sigframe() overwrites PKRU in XSAVE buffer ... signal handling * XRSTOR sees XSTATE_BV[PKRU]==0, ignores just-written value from update_pkru_in_sigframe() Fixes: 70044df250d0 ("x86/pkeys: Update PKRU to enable all pkeys before XSAVE") Suggested-by: Rudi Horn Signed-off-by: Aruna Ramakrishna Signed-off-by: Dave Hansen Acked-by: Dave Hansen Link: https://lore.kernel.org/all/20241119174520.3987538-3-aruna.ramakrishna%40oracle.com --- arch/x86/kernel/fpu/xstate.h | 16 ++++++++++++++-- 1 file changed, 14 insertions(+), 2 deletions(-) diff --git a/arch/x86/kernel/fpu/xstate.h b/arch/x86/kernel/fpu/xstate.h index 6b2924fbe5b8d..aa16f1a1bbcf1 100644 --- a/arch/x86/kernel/fpu/xstate.h +++ b/arch/x86/kernel/fpu/xstate.h @@ -72,10 +72,22 @@ static inline u64 xfeatures_mask_independent(void) /* * Update the value of PKRU register that was already pushed onto the signal frame. */ -static inline int update_pkru_in_sigframe(struct xregs_state __user *buf, u32 pkru) +static inline int update_pkru_in_sigframe(struct xregs_state __user *buf, u64 mask, u32 pkru) { + u64 xstate_bv; + int err; + if (unlikely(!cpu_feature_enabled(X86_FEATURE_OSPKE))) return 0; + + /* Mark PKRU as in-use so that it is restored correctly. */ + xstate_bv = (mask & xfeatures_in_use()) | XFEATURE_MASK_PKRU; + + err = __put_user(xstate_bv, &buf->header.xfeatures); + if (err) + return err; + + /* Update PKRU value in the userspace xsave buffer. */ return __put_user(pkru, (unsigned int __user *)get_xsave_addr_user(buf, XFEATURE_PKRU)); } @@ -292,7 +304,7 @@ static inline int xsave_to_user_sigframe(struct xregs_state __user *buf, u32 pkr clac(); if (!err) - err = update_pkru_in_sigframe(buf, pkru); + err = update_pkru_in_sigframe(buf, mask, pkru); return err; } From 0f15cbc203712ccad363611eded31a2c700f3974 Mon Sep 17 00:00:00 2001 From: Mario Limonciello Date: Wed, 27 Nov 2024 21:25:00 -0600 Subject: [PATCH 0200/1256] drm/amd: Sanity check the ACPI EDID An HP Pavilion Aero Laptop 13-be0xxx/8916 has an ACPI EDID, but using it is causing corruption.

The mask bits vary across SMU versions. Move all handling of smu->workload_mask in to the backends and simplify the code. Store the user's preference in smu->power_profile_mode which will be reflected in sysfs. For internal driver profile switches for KFD or VCN, just update the workload mask so that the user's preference is retained. Remove all of the extra now unused workload related elements in the smu structure. v2: use refcounts for workload profiles v3: rework based on feedback from Lijo v4: fix the refcount on failure, drop backend mask v5: rework custom handling v6: handle failure cleanup with custom profile v7: Update documentation Reviewed-by: Lijo Lazar Signed-off-by: Alex Deucher Cc: Kenneth Feng Cc: Lijo Lazar Cc: stable@vger.kernel.org # 6.11.x --- drivers/gpu/drm/amd/pm/amdgpu_pm.c | 6 +- drivers/gpu/drm/amd/pm/swsmu/amdgpu_smu.c | 150 ++++++++++------ drivers/gpu/drm/amd/pm/swsmu/inc/amdgpu_smu.h | 15 +- .../gpu/drm/amd/pm/swsmu/smu11/arcturus_ppt.c | 166 +++++++++-------- .../gpu/drm/amd/pm/swsmu/smu11/navi10_ppt.c | 167 ++++++++++------- .../amd/pm/swsmu/smu11/sienna_cichlid_ppt.c | 168 +++++++++++------- .../gpu/drm/amd/pm/swsmu/smu11/vangogh_ppt.c | 41 ++--- .../gpu/drm/amd/pm/swsmu/smu12/renoir_ppt.c | 43 ++--- .../drm/amd/pm/swsmu/smu13/smu_v13_0_0_ppt.c | 167 +++++++++-------- .../drm/amd/pm/swsmu/smu13/smu_v13_0_7_ppt.c | 138 ++++++++------ .../drm/amd/pm/swsmu/smu14/smu_v14_0_2_ppt.c | 168 +++++++++++------- drivers/gpu/drm/amd/pm/swsmu/smu_cmn.c | 25 +++ drivers/gpu/drm/amd/pm/swsmu/smu_cmn.h | 4 + 13 files changed, 741 insertions(+), 517 deletions(-) diff --git a/drivers/gpu/drm/amd/pm/amdgpu_pm.c b/drivers/gpu/drm/amd/pm/amdgpu_pm.c index 136e8193867c3..e8ae7681bf0a3 100644 --- a/drivers/gpu/drm/amd/pm/amdgpu_pm.c +++ b/drivers/gpu/drm/amd/pm/amdgpu_pm.c @@ -1361,7 +1361,11 @@ static ssize_t amdgpu_set_pp_mclk_od(struct device *dev, * create a custom set of heuristics, write a string of numbers to the file * starting with the number of the custom profile along with a setting * for each heuristic parameter.

The offending commit results in errors like cpu cpu0: _opp_config_clk_single: failed to set clock rate: -22 spamming the logs on the Lenovo ThinkPad X13s and other Qualcomm machines when cpufreq tries to update the CPUFreq HW Engine clocks. As mentioned in commit 4370232c727b ("cpufreq: qcom-hw: Add CPU clock provider support"): [T]he frequency supplied by the driver is the actual frequency that comes out of the EPSS/OSM block after the DCVS operation. This frequency is not same as what the CPUFreq framework has set but it is the one that gets supplied to the CPUs after throttling by LMh. which seems to suggest that the driver relies on the previous behaviour of clk_set_rate(). Since this affects many Qualcomm machines, let's revert for now.

Instead of enforcing this in the caller of process_iter_arg, move the check into it instead so that all callers will gain the check by default. This is similar to process_dynptr_func. An existing selftest in verifier_bits_iter.c fails due to this change, but it's because it was passing a NULL pointer into iter_next helper and getting an error further down the checks, but probably meant to pass an uninitialized iterator on the stack (as is done in the subsequent test below it). We will gain coverage for non-PTR_TO_STACK arguments in later patches hence just change the declaration to zero-ed stack object.

Due to a hardware limitation, the PHY cannot reliably update link status after parallel detection when the link partner does not support auto-negotiation. To mitigate this, add a PHY reset in `lan88xx_link_change_notify()` when `phydev->state` is `PHY_NOLINK`, ensuring the PHY starts in a clean state and reports accurate fixed link parallel detection results.

There are several conditions that must be fulfilled for the leak to occur: * an ICMPv6 packet indicating a change of the MTU for the path is received, resulting in an exception dst being created * a TCP connection that uses the exception dst for routing packets must start timing out so that TCP begins retransmissions * after the exception dst expires, the FIB6 garbage collector must not run before TCP executes ip6_negative_advice() for the expired exception dst When TCP executes ip6_negative_advice() for an exception dst that has expired and if no other socket holds a reference to the exception dst, the refcount of the exception dst is 2, which corresponds to the increment made by dst_init() and the increment made by the TCP socket for which the connection is timing out. The refcount made by the socket is never released. The refcount of the dst is decremented in sk_dst_reset() but that decrement is counteracted by a dst_hold() intentionally placed just before the sk_dst_reset() in ip6_negative_advice(). After ip6_negative_advice() has finished, there is no other object tied to the dst. The socket lost its reference stored in sk_dst_cache and the dst is no longer in the exception table. The exception dst becomes a leaked object. As a result of this dst leak, an unbalanced refcount is reported for the loopback device of a net namespace being destroyed under kernels that do not contain e5f80fcf869a ("ipv6: give an IPv6 dev to blackhole_netdev"): unregister_netdevice: waiting for lo to become free. Usage count = 2 Fix the dst leak by removing the dst_hold() in ip6_negative_advice(). The patch that introduced the dst_hold() in ip6_negative_advice() was 92f1655aa2b22 ("net: fix __dst_negative_advice() race"). But 92f1655aa2b22 merely refactored the code with regards to the dst refcount so the issue was present even before 92f1655aa2b22. The bug was introduced in 54c1a859efd9f ("ipv6: Don't drop cache route entry unless timer actually expired.") where the expired cached route is deleted and the sk_dst_cache member of the socket is set to NULL by calling dst_negative_advice() but the refcount belonging to the socket is left unbalanced. The IPv4 version - ipv4_negative_advice() - is not affected by this bug. When the TCP connection times out ipv4_negative_advice() merely resets the sk_dst_cache of the socket while decrementing the refcount of the exception dst. Fixes: 92f1655aa2b22 ("net: fix __dst_negative_advice() race") Fixes: 54c1a859efd9f ("ipv6: Don't drop cache route entry unless timer actually expired.")

This causes boot regressions on the ARMv4, ARMv5, ARMv6 and ARMv7 i.MX SoCs. Fix it by selecting CONFIG_PINCTRL as before. This defeats the purpose of 7d210018914 ("ARM: imx: Allow user to disable pinctrl"), but it is the less invasive fix for the boot regressions. The attempt to build Layerscape without pinctrl can still be explored later as suggested by Arnd: "Overall, my best advice here is still to not change the way i.MX pinctrl works at all, but just fix Layerscape to not depend on i.MX. The reason for the 'select' here is clearly that the i.MX machines would fail to boot without pinctrl, and changing that because of Layerscape seems backwards."

This led to blocked queues that prevented any activity (even disconnection wouldn't reset the queue state and the only way to recover would be to reload the kernel module.

This looks safer, however, it leads to a classic Time-of-Check to Time-of-Use (TOCTOU) bug since IFLA_NET_NS_PID is very dynamic. And because of the lack of checking error pointer of the second call, it also leads to a kernel crash as reported by syzbot. Fix this by getting rid of the second call, which already becomes redudant after Kuniyuki's work. We have to propagate the result of the first rtnl_link_get_net_ifla() down to each ->newlink().

Commit 122c234ef4e1 ("arm64: mm: keep low RAM dma zone") further fixed this to ensure ZONE_DMA remains below U32_MAX if RAM starts below 4GB, especially on platforms that do not have IORT or DT description of the device DMA ranges. While zone boundaries calculation was fixed by the latter commit, zone_dma_limit, used to determine the GFP_DMA flag in the core code, was not updated. This results in excessive use of GFP_DMA and unnecessary ZONE_DMA allocations on some platforms. Update zone_dma_limit to match the actual upper bound of ZONE_DMA.

Indeed, some goto calls are done from a loop without setting the ret value explicitly before the goto call and so the ret value can be set to 0 due to operation done in previous loop iteration. For instance match can be set to 0 in the previous loop iteration (leading to a new iteration) but ret can also be set to 0 it the of_property_read_u32() call succeed. In that case if no match are found or if an error is detected the new iteration, the return value can be wrongly 0. Avoid those cases setting the ret value explicitly before the goto calls.

Before that commit, the arithmetic performed by page_to_phys() would give the expected physical address, though it is somewhat dubious to use vmemmap addresses before the vmemmap has been initialized. Aside from kernel image addresses, all executable code should be allocated from execmem (where all allocations will fall within the vmalloc area), and so there's no need for the fallback case when CONFIG_EXECMEM=n. Simplify patch_map() accordingly, directly converting kernel image addresses and removing the redundant fallback case.

When a frag is too large for a single data descriptor, it will be split across multiple data descriptors. This means the frag will span multiple buffers in the buffer ring in order to keep the descriptor and buffer ring indexes aligned. The buffer entries in the ring are technically empty and no cleaning actions need to be performed. These empty buffers can precede other frags associated with the same packet. I.e. a single packet on the buffer ring can look like: buf[0]=skb0.frag0 buf[1]=skb0.frag1 buf[2]=empty buf[3]=skb0.frag2 The cleaning routine iterates through these buffers based on a matching completion tag. If the completion tag is not set for buf2, the loop will end prematurely. Frag2 will be left uncleaned and next_to_clean will be left pointing to the end of packet, which will break the cleaning logic for subsequent cleans. This consequently leads to tx timeouts. Assign the empty bufs the same completion tag for the packet to ensure the cleaning routine iterates over all of the buffers associated with the packet.

This commit mistakenly enabled IPSEC offload for API v1.5. No implementation of the v1.5 API has support for IPSEC offload. This offload is only supported by the Linux PF as mailbox API v1.4. In fact, the v1.5 API is not implemented in any Linux PF. Attempting to enable IPSEC offload on a PF which supports v1.5 API will not work. Only the Linux upstream ixgbe and ixgbevf support IPSEC offload, and only as part of the v1.4 API. Fix the ixgbevf Linux driver to stop attempting IPSEC offload when the mailbox API does not support it. The existing API design choice makes it difficult to support future API versions, as other non-Linux hosts do not implement IPSEC offload. If we add support for v1.5 to the Linux PF, then we lose support for IPSEC offload. A full solution likely requires a new mailbox API with a proper negotiation to check that IPSEC is actually supported by the host.

The Linux PF only supports API v1.4, and does not currently have support for the v1.5 API. The logged message can confuse users, as the v1.5 API is valid, but just happens to not currently be supported by the Linux PF. Downgrade the info message to a debug message, and fix the language to use 'unsupported' instead of 'invalid' to improve message clarity. Long term, we should investigate whether the improvements in the v1.5 API make sense for the Linux PF, and if so implement them properly. This may require yet another API version to resolve issues with negotiating IPSEC offload support.

The queue limit no longer exists as every user of it has been converted to use the write zeroes operation instead. The quirk now means to use a discard command as an alias to a write zeroes request. Two of the devices previously using the quirk support the write zeroes command directly, so these don't need or want to use discard when the desired operation is to write zeroes.

[CAUSE] During the btrfs mount, to support mounting different subvolumes with different RO/RW flags, we need to detect that and retry if needed: Retry with matching RO flags if the initial mount fail with -EBUSY. The problem is, during that retry we do not hold any super block lock (s_umount), this means there can be a remount process changing the RO flags of the original fs super block. If so, we can have an EBUSY error during retry. And this time we treat any failure as an error, without any retry and cause the above EBUSY mount failure. [FIX] The current retry behavior is racy because we do not have a super block thus no way to hold s_umount to prevent the race with remount. Solve the root problem by allowing fc->sb_flags to mismatch from the sb->s_flags at btrfs_get_tree_super(). Then at the re-entry point btrfs_get_tree_subvol(), manually check the fc->s_flags against sb->s_flags, if it's a RO->RW mismatch, then reconfigure with s_umount lock hold.

This was in conflict with a different page in the Documentration that state that the BUS runs at 300MHz (600MHz source with divisor set to 2) and the actual watchdog that tick at half the BUS clock (150MHz). This was verified with the watchdog by timing the seconds that the system takes to reboot (due too watchdog) and by operating on different values of the BUS divisor. The correct values for source of BUS clock are 600MHz and 540MHz. This was also confirmed by Airoha.

This could lead to missed invalidations if the guest was lead to assume that the HW had 8 bit ASIDs while they really are 16 bit wide. In order to avoid any potential disaster that would be hard to debug, prenent the migration between a host with 8 bit ASIDs to one with wider ASIDs (the converse was obviously always forbidden). This is also consistent with what we already do for VMIDs. If it becomes absolutely mandatory to support such a migration path in the future, we will have to trap and emulate all TLBIs, something that nobody should look forward to.

Then we pass the result to uverbs_request_next_ptr() which also could potentially wrap. The "cmd.sge_count * sizeof(struct ib_uverbs_sge)" multiplication can also overflow on 32bit systems although it's fine on 64bit systems. This patch does two things. First, I've re-arranged the condition in uverbs_request_next_ptr() so that the use controlled variable "len" is on one side of the comparison by itself without any math. Then I've modified all the callers to use size_mul() for the multiplications.

The uart_suspend_port() calls 3 times the struct uart_port::ops::tx_empty() before shutting down the port. According to the documentation, the struct uart_port::ops::tx_empty() API tests whether the transmitter FIFO and shifter for the port is empty. The Renesas RZ/G3S SCIFA IP reports the number of data units stored in the transmit FIFO through the FDR (FIFO Data Count Register). The data units in the FIFOs are written in the shift register and transmitted from there. The TEND bit in the Serial Status Register reports if the data was transmitted from the shift register. In the previous code, in the tx_empty() API implemented by the sh-sci driver, it is considered that the TX is empty if the hardware reports the TEND bit set and the number of data units in the FIFO is zero. According to the HW manual, the TEND bit has the following meaning: 0: Transmission is in the waiting state or in progress. 1: Transmission is completed. It has been noticed that when opening the serial device w/o using it and then switch to a power saving mode, the tx_empty() call in the uart_port_suspend() function fails, leading to the "Unable to drain transmitter" message being printed on the console. This is because the TEND=0 if nothing has been transmitted and the FIFOs are empty. As the TEND=0 has double meaning (waiting state, in progress) we can't determined the scenario described above. Add a software workaround for this. This sets a variable if any data has been sent on the serial console (when using PIO) or if the DMA callback has been called (meaning something has been transmitted). In the tx_empty() API the status of the DMA transaction is also checked and if it is completed or in progress the code falls back in checking the hardware registers instead of relying on the software variable.

However, in such a scenario, it rejects all partial stack overwrites as long as the targeted stack slot is a spilled register, because it does not check if the stack slot is a spilled pointer. Incomplete checks will result in the rejection of valid programs, which spill narrower scalar values onto scalar slots, as shown below. 0: R1=ctx() R10=fp0 ; asm volatile ( @ repro.bpf.c:679 0: (7a) *(u64 *)(r10 -8) = 1 ; R10=fp0 fp-8_w=1 1: (62) *(u32 *)(r10 -8) = 1 attempt to corrupt spilled pointer on stack processed 2 insns (limit 1000000) max_states_per_insn 0 total_states 0 peak_states 0 mark_read 0.

Since we do not want to include linux/capability.h, we only defined the four main capabilities BPF subsystem deals with in bpf_misc.h for use in tests. If the user passes a CAP_SYS_NICE or anything else that's not defined in the header, capability parsing code will return a warning. Also reject strtol returning 0.

However, some NVMe/TCP and NVMe/FC arrays from major vendors have buggy firmware that reports MAXCMD as zero in the Identify Controller data structure. Currently, the implementation closes the connection in such cases, completely preventing the host from connecting to the target. Fix the issue by printing a clear error message about the firmware bug and allowing the connection to proceed. It assumes that the target supports a MAXCMD value of SQSIZE + 1. If any issues arise, the user can manually adjust SQSIZE to mitigate them.

The kref_put() call may decrement the reference count of sfp to zero, triggering its cleanup through sg_remove_sfp(). This cleanup includes scheduling deferred work via sg_remove_sfp_usercontext(), which ultimately frees sfp. After kref_put(), sg_release() continues to unlock open_rel_lock and may reference sfp or sdp. If sfp has already been freed, this results in a slab-use-after-free error. Move the kref_put(&sfp->f_ref, sg_remove_sfp) call after unlocking the open_rel_lock mutex. This ensures: - No references to sfp or sdp occur after the reference count is decremented. - Cleanup functions such as sg_remove_sfp() and sg_remove_sfp_usercontext() can safely execute without impacting the mutex handling in sg_release(). The fix has been tested and validated by syzbot. This patch closes the bug reported at the following syzkaller link and ensures proper sequencing of resource cleanup and mutex operations, eliminating the risk of use-after-free errors in sg_release().

I considered that checking for errors when calling rhashtable_walk_next() was sufficient to detect the resizing. However, rhashtable_walk_next() returns -EAGAIN only at the end of the iteration, which is too late, because a gc work containing duplicated elements could have been already scheduled for removal to the worker. Add a u32 gc worker sequence number per set, bump it on every workqueue run. Annotate gc worker sequence number on the expired element. Use it to skip those already seen in this gc workqueue run. Note that this new field is never reset in case gc transaction fails, so next gc worker run on the expired element overrides it. Wraparound of gc worker sequence number should not be an issue with stale gc worker sequence number in the element, that would just postpone the element removal in one gc run. Note that it is not possible to use flags to annotate that element is pending gc run to detect duplicates, given that gc transaction can be invalidated in case of update from the control plane, therefore, not allowing to clear such flag. On x86_64, pahole reports no changes in the size of nft_rhash_elem.

This can lead to out-of-bounds access and undefined behavior if the buffer does not have sufficient space. To address this, a check was added in acpi_nfit_ctl() to ensure that buf is not NULL and that buf_len is less than sizeof(*call_pkg) before accessing it. This ensures safe access to the members of call_pkg, including the nd_reserved2 array.

Such a case is not currently matched by the ipmr_can_free_table() helper. New namespaces are zeroed on allocation and inserted into net ns list only after successful creation; when deleting an ipmr table, the list next pointer can be NULL only on netns initialization failure. Update the ipmr_can_free_table() checks leveraging such condition.

This works correctly for compact format but when verbose format is parsed, ethnl_update_bitset32_verbose() only sets the bits present in the request bitset but does not clear the rest. The commit 6699170376ab ("ethtool: fix application of verbose no_mask bitset") fixes this issue by clearing the whole target bitmap before we start iterating. The solution proposed brought an issue with the behavior of the mod variable. As the bitset is always cleared the old value will always differ to the new value. Fix it by adding a new function to compare bitmaps and a temporary variable which save the state of the old bitmap.

This works because the driver is only using a single field from this key block which is located in the same offset in the equivalent Spectrum-4 key block. The issue was discovered when the firmware started rejecting the use of the unsupported key block. The change has been reverted to avoid breaking users that only update their firmware. Nonetheless, fix the issue by using the correct key block.

Prior to this change, frags used in the TPA ring rx_tpa were allocated from system memory e.g. napi_alloc_frag() meaning their lifetimes were not associated with a page pool. They can be returned at any time and so the queue API did not alloc or free rx_tpa. But now frags come from a separate head_pool which may be different to page_pool. Without allocating and freeing rx_tpa, frags allocated from the old head_pool may be returned to a different new head_pool which causes a mismatch between the pp hold/release count. Fix this problem by properly freeing and allocating rx_tpa in the queue API implementation.

In the cited commit, where this support was added, the channel_param logic was mistakenly kept unchanged, so it always used the primary PF which is found at priv->mdev. In this patch we fix this by moving the logic to be per-channel, and passing the correct mdev instance. This bug happened to be usually harmless, as the resulting cparam structures would be the same for all channels, due to identical FW logic and decisions. However, in some use cases, like fwreset, this gets broken. This could lead to different symptoms.

It is triggered when offload a rule with tunnel encapsulation, and forwarding to another table, but not matching on the internal port in firmware steering mode. The original workaround skips internal tunnel port logic, which is not correct as not all cases are considered. As an example, if vlan is configured on the uplink port, traffic can't pass because vlan header is not added with this workaround. Besides, there is no such issue for software steering. So, this patch removes that, and returns error directly if trying to offload such rule for firmware steering.

This double assertion causes incorrect read and write operations. The issue occurs because when nfc->ncs <= 2, nfc->spare_cs is always initialized to 0 due to static initialization. Consequently, when the second chip-select (GPIO-based) is selected in anfc_assert_cs(), it is detected by anfc_is_gpio_cs(), and nfc->native_cs is assigned the value 0. This results in both the GPIO-based chip-select being asserted and the NAND controller register receiving 0, erroneously selecting the native chip-select. This patch resolves the issue, as confirmed by oscilloscope testing with configurations involving two or more chip-selects in the device tree.

SO_RCVLOWAT requires an int parameter. However, instead of int, the test uses unsigned long in one place and size_t in another. Both are 8 bytes long on 64-bit machines. The kernel, having received the 8 bytes, doesn't test for the exact size of the parameter, it only cares that it's >= sizeof(int), and casts the 4 lower-addressed bytes to an int, which, on a big-endian machine, contains 0. 0 doesn't trigger an error, SO_RCVLOWAT returns with success and the socket stays with the default SO_RCVLOWAT = 1, which results in vsock_test failures, while vsock_perf doesn't even notice that it's failed to change it.

On an 8-bit ASID CPU, this is RES0 and ignored, otherwise 16-bit ASIDs are enabled. However, if running in a VM and the hypervisor reports 8-bit ASIDs (ID_AA64MMFR0_EL1.ASIDBits == 0) on a 16-bit ASIDs CPU, Linux uses bits 8 to 63 as a generation number for tracking old process ASIDs. The bottom 8 bits of this generation end up being written to TTBR1_EL1 and also used for the ASID-based TLBI operations as the upper 8 bits of the ASID. Following an ASID roll-over event we can have threads of the same application with the same 8-bit ASID but different generation numbers running on separate CPUs. Both TLB caching and the TLBI operations will end up using different actual 16-bit ASIDs for the same process. A similar scenario can happen in a big.LITTLE configuration if the boot CPU only uses 8-bit ASIDs while secondary CPUs have 16-bit ASIDs. Ensure that the ASID generation is only tracked by bits 16 and up, leaving bits 15:8 as 0 if the kernel uses 8-bit ASIDs. Note that clearing TCR_EL1.AS is not sufficient since the architecture requires that the top 8 bits of the ASID passed to TLBI instructions are 0 rather than ignored in such configuration.

However, users of the kernel_ident_mapping_init() code do not give it an 8KiB allocation for its PGD. Both swsusp_arch_resume() and acpi_mp_setup_reset() allocate only a single 4KiB page. The kexec code on x86_64 currently gets away with it purely by chance, because it allocates 8KiB for its "control code page" and then actually uses the first half for the PGD, then copies the actual trampoline code into the second half only after the identmap code has finished scribbling over it. Fix this by defining a _PAGE_NOPTISHADOW bit (which can use the same bit as _PAGE_SAVED_DIRTY since one is only for the PGD/P4D root and the other is exclusively for leaf PTEs.). This instructs __pti_set_user_pgtbl() not to write to the userspace 'shadow' PGD. Strictly, the _PAGE_NOPTISHADOW bit doesn't need to be written out to the actual page tables; since __pti_set_user_pgtbl() returns the value to be written to the kernel page table, it could be filtered out. But there seems to be no benefit to actually doing so.

The race is possible since the reader/parser doesn't hold any lock while accessing the reception state. This in turn can lead to a memory corruption in the reader/parser as described by commit bd2fccac61b4 ("drm/dp_mst: Fix MST sideband message body length check"). Fix the above by resetting the message reception state if needed before reading/parsing a message. Another solution would be to hold the drm_dp_mst_topology_mgr::lock for the whole duration of the message reception/parsing in drm_dp_mst_handle_down_rep() and drm_dp_mst_handle_up_req(), however this would require a bigger change. Since the fix is also needed for stable, opting for the simpler solution in this patch.

There are some cases that would call a tracepoint when RCU was not "watching". This was usually in the idle path where RCU has "shutdown". For the few locations that had tracepoints without RCU watching, there was an trace_*_rcuidle() variant that could be used. This used SRCU for protection. There are tracepoints that trace when interrupts and preemption are enabled and disabled. In some architectures, these tracepoints are called in a path where RCU is not watching. When x86 and arm64 removed these locations, it was incorrectly assumed that it would be safe to remove the trace_*_rcuidle() variant and also remove the SRCU logic, as it made the code more complex and harder to implement new tracepoint features (like faultable tracepoints and tracepoints in rust). Instead of bringing back the trace_*_rcuidle(), as it will not be trivial to do as new code has already been added depending on its removal, add a workaround to the one file that still requires it (trace_preemptirq.c). If the architecture does not define CONFIG_ARCH_WANTS_NO_INSTR, then check if the code is in the idle path, and if so, call ct_irq_enter/exit() which will enable RCU around the tracepoint.

It turns out that the calculated maximal idle time, which limits idle sleeps to prevent clocksource wrap arounds, is close to the point where the negative motion detection triggers. max_idle_ns: 597268854 ns negative motion tripping point: 671088640 ns If the idle wakeup is delayed beyond that point, the clocksource advances far enough to trigger the negative motion detection. This prevents the clock to advance and in the worst case the system stalls completely if the consecutive sleeps based on the stale clock are delayed as well. Cure this by calculating a more robust cut-off value for negative motion, which covers 87.5% of the actual clocksource counter width. Compare the delta against this value to catch negative motion. This is specifically for clock sources with a small counter width as their wrap around time is close to the half counter width. For clock sources with wide counters this is not a problem because the maximum idle time is far from the half counter width due to the math overflow protection constraints. For the case at hand this results in a tripping point of 1174405120ns. Note, that this cannot prevent issues when the delay exceeds the 87.5% margin, but that's not different from the previous unchecked version which allowed arbitrary time jumps. Systems with small counter width are prone to invalid results, but this problem is unlikely to be seen on real hardware. If such a system completely stalls for more than half a second, then there are other more urgent problems than the counter wrapping around.

Previously, the check was performed on the first element of the response message, which was accessed using a 32-bit pointer. This caused the bitwise operation to reference incorrect data, as the response should be inspected at the byte level. Fixed this by casting the response to a u8 * pointer, ensuring the check correctly inspects the appropriate byte of the response message. Additionally, rename "UL_Auto Update" to "UL_IAP" to match the PolarFire Family System Services User Guide.

And the motivation is to drain inflight IOs before suspending. block layer's queue freeze looks very handy, but it is also easy to cause deadlock, such as, any attempt to call into bio_queue_enter() may run into deadlock if the queue is frozen in current context. There are all kinds of ->suspend() called in suspend context, so keeping queue frozen in the whole suspend context isn't one good idea. And Marek reported lockdep warning[1] caused by virtio-blk's freeze queue in virtblk_freeze(). [1] https://lore.kernel.org/linux-block/ca16370e-d646-4eee-b9cc-87277c89c43c@samsung.com/ Given the motivation is to drain in-flight IOs, it can be done by calling freeze & unfreeze, meantime restore to previous behavior by keeping queue quiesced during suspend.

As a result, their values accumulate until they overflow. The expected behavior is for performance counters to reset to zero at the start of a job. When the job finishes and the perfmon is stopped, the counters should accurately reflect the values for that specific job. To ensure this behavior, the performance counters are now enabled before being cleared. This allows the CLR register to function as intended, zeroing the counter values when the job begins.

This adjustment resolves a mismatch on systems where PAGE_SIZE is 64K, but the firmware only supports a maximum message size of 4K. Now that we rely on the device's capability for max_message_size, we must account for potential future increases in its value. Key considerations include: - Supporting message sizes that exceed a single system page (e.g., an 8K message on a 4K system). - Ensuring the RQ size is adjusted to accommodate at least 4 WQEs/messages, in line with the device specification. The above has been addressed as part of the patch.

For the high workload, the performance is the same between 3D fullscreen mode and bootup mode. v2: set the default workload in ASIC specific file Signed-off-by: Kenneth Feng Reviewed-by: Yang Wang Signed-off-by: Alex Deucher Cc: stable@vger.kernel.org # 6.11.x --- drivers/gpu/drm/amd/pm/swsmu/smu13/smu_v13_0_7_ppt.c | 1 + 1 file changed, 1 insertion(+) diff --git a/drivers/gpu/drm/amd/pm/swsmu/smu13/smu_v13_0_7_ppt.c b/drivers/gpu/drm/amd/pm/swsmu/smu13/smu_v13_0_7_ppt.c index f4ac403b8b360..aabb947960056 100644 --- a/drivers/gpu/drm/amd/pm/swsmu/smu13/smu_v13_0_7_ppt.c +++ b/drivers/gpu/drm/amd/pm/swsmu/smu13/smu_v13_0_7_ppt.c @@ -2810,4 +2810,5 @@ void smu_v13_0_7_set_ppt_funcs(struct smu_context *smu) smu->workload_map = smu_v13_0_7_workload_map; smu->smc_driver_if_version = SMU13_0_7_DRIVER_IF_VERSION; smu_v13_0_set_smu_mailbox_registers(smu); + smu->power_profile_mode = PP_SMC_POWER_PROFILE_BOOTUP_DEFAULT; } From 5c3de6b02d38eb9386edf50490e050bb44398e40 Mon Sep 17 00:00:00 2001 From: Prike Liang Date: Tue, 5 Nov 2024 09:57:42 +0800 Subject: [PATCH 0444/1256] drm/amdkfd: Correct the migration DMA map direction The SVM DMA device map direction should be set the same as the DMA unmap setting, otherwise the DMA core will report the following warning. Before finialize this solution, there're some discussion on the DMA mapping type(stream-based or coherent) in this KFD migration case, followed by https://lore.kernel.org/all/04d4ab32 -45a1-4b88-86ee-fb0f35a0ca40@amd.com/T/. As there's no dma_sync_single_for_*() in the DMA buffer accessed that because this migration operation should be sync properly and automatically. Give that there's might not be a performance problem in various cache sync policy of DMA sync. Therefore, in order to simplify the DMA direction setting alignment, let's set the DMA map direction as BIDIRECTIONAL.

This is because nilfs_last_byte(), which is called by nilfs_find_entry() and others to calculate the number of valid bytes of directory data in a page from i_size and the page index, loses the upper 32 bits of the 64-bit size information due to an inappropriate type of local variable to which the i_size value is assigned. This caused a large byte offset value due to underflow in the end address calculation in the calling nilfs_find_entry(), resulting in memory access that exceeds the folio/page size. Fix this issue by changing the type of the local variable causing the bit loss from "unsigned int" to "u64". The return value of nilfs_last_byte() is also of type "unsigned int", but it is truncated so as not to exceed PAGE_SIZE and no bit loss occurs, so no change is required.

Anders and Philippe have reported that recent kernels occasionally hang when used with NFS in readahead code. The problem has been bisected to 7c877586da3 ("readahead: properly shorten readahead when falling back to do_page_cache_ra()"). The cause of the problem is that ra->size can be shrunk by read_pages() call and subsequently we end up calling do_page_cache_ra() with negative (read huge positive) number of pages. Let's revert 7c877586da3 for now until we can find a proper way how the logic in read_pages() and page_cache_ra_order() can coexist. This can lead to reduced readahead throughput due to readahead window confusion but that's better than outright hangs.

It does this by effectively looking up a region that is of size, request_size + PMD_SIZE, and aligning up the start to a PMD boundary. Commit 4ef9ad19e176 ("mm: huge_memory: don't force huge page alignment on 32 bit") opted out of this for 32bit due to regressions in mmap base randomization. Commit d4148aeab412 ("mm, mmap: limit THP alignment of anonymous mappings to PMD-aligned sizes") restricted this to only mmap sizes that are multiples of the PMD_SIZE due to reported regressions in some performance benchmarks -- which seemed mostly due to the reduced spatial locality of related mappings due to the forced PMD-alignment. Another unintended side effect has emerged: When a user specifies an mmap hint address, the THP alignment logic modifies the behavior, potentially ignoring the hint even if a sufficiently large gap exists at the requested hint location. Example Scenario: Consider the following simplified virtual address (VA) space: ... 0x200000-0x400000 --- VMA A 0x400000-0x600000 --- Hole 0x600000-0x800000 --- VMA B ... A call to mmap() with hint=0x400000 and len=0x200000 behaves differently: - Before THP alignment: The requested region (size 0x200000) fits into the gap at 0x400000, so the hint is respected. - After alignment: The logic searches for a region of size 0x400000 (len + PMD_SIZE) starting at 0x400000. This search fails due to the mapping at 0x600000 (VMA B), and the hint is ignored, falling back to arch_get_unmapped_area[_topdown](). In general the hint is effectively ignored, if there is any existing mapping in the below range: [mmap_hint + mmap_size, mmap_hint + mmap_size + PMD_SIZE) This changes the semantics of mmap hint; from ""Respect the hint if a sufficiently large gap exists at the requested location" to "Respect the hint only if an additional PMD-sized gap exists beyond the requested size". This has performance implications for allocators that allocate their heap using mmap but try to keep it "as contiguous as possible" by using the end of the exisiting heap as the address hint. With the new behavior it's more likely to get a much less contiguous heap, adding extra fragmentation and performance overhead. To restore the expected behavior; don't use thp_get_unmapped_area_vmflags() when the user provided a hint address, for anonymous mappings. Note: As Yang Shi pointed out: the issue still remains for filesystems which are using thp_get_unmapped_area() for their get_unmapped_area() op. It is unclear what worklaods will regress for if we ignore THP alignment when the hint address is provided for such file backed mappings -- so this fix will be handled separately.

This makes const_folio_flags VM_BUG_ON_PGFLAGS() when stumbling over the tail page. Could this result in other issues? Doesn't look like it. False positives and false negatives don't really matter, because this folio would get skipped either way when detecting that they have been reallocated in the meantime. Fix it by performing the folio_test_locked() checked after grabbing a reference. If this ever becomes a real problem, we could add a special helper that racily checks if the bit is set even on tail pages ... but let's hope that's not required so we can just handle it cleaner: work on the folio after we hold a reference. Do we really need the folio_test_locked() check if we are going to trylock briefly after? Well, we can at least avoid a xas_reload(). It's a bit unclear which exact change introduced that issue. Likely, ever since we made PG_locked obey to the PF_NO_TAIL policy it could have been triggered in some way.

When two or more cores observe that vma->numab_state is NULL at the same time, vma->numab_state will be overwritten. Although current code ensures that only one thread scans the VMAs in a single 'numa_scan_period', there might be a chance for another thread to enter in the next 'numa_scan_period' while we have not gotten till numab_state allocation [1]. Note that the command `/opt/ltp/testcases/bin/hackbench 50 process 1000` cannot the reproduce the issue. It is verified with 200+ test runs. [Solution] Use the cmpxchg atomic operation to ensure that only one thread executes the vma->numab_state assignment.

The input clamp value h[] is of type s32. The BIT() is of type unsigned long integer due to its define in include/vdso/bits.h. The lower limit -BIT(13) is recognized as -8192 but expressed as an unsigned long integer. The size of an unsigned long integer differs between 32-bit and 64-bit architectures. Converting this to type s32 may lead to undesired behavior. Additionally, in the calculation lines h[0], h[1] and h[2] the unsigned long integer divisor BIT(13) causes an unsigned division, shifting the left-hand side of the equation back and forth, possibly ending up in large positive values instead of negative values on 32-bit architectures. To solve those two issues, declare a signed integer with a value of BIT(13). There is another omission in the clamp line: clamp_val() returns a value and it's going nowhere here.

Commit 6539cffa9495 ("cacheinfo: Add arch specific early level initializer") lets secondary CPUs correct (and reallocate memory) cacheinfo data if needed. If the early build functionality is not used and cacheinfo does not need correction, memory for cacheinfo is never allocated. x86 does not use the early build functionality. Consequently, during the cacheinfo CPU hotplug callback, last_level_cache_is_valid() attempts to dereference a NULL pointer: BUG: kernel NULL pointer dereference, address: 0000000000000100 #PF: supervisor read access in kernel mode #PF: error_code(0x0000) - not present page PGD 0 P4D 0 Oops: 0000 [#1] PREEPMT SMP NOPTI CPU: 0 PID 19 Comm: cpuhp/0 Not tainted 6.4.0-rc2 #1 RIP: 0010: last_level_cache_is_valid+0x95/0xe0a Allocate memory for cacheinfo during the cacheinfo CPU hotplug callback if not done earlier. Moreover, before determining the validity of the last-level cache info, ensure that it has been allocated. Simply checking for non-zero cache_leaves() is not sufficient, as some architectures (e.g., Intel processors) have non-zero cache_leaves() before allocation. Dereferencing NULL cacheinfo can occur in update_per_cpu_data_slice_size(). This function iterates over all online CPUs. However, a CPU may have come online recently, but its cacheinfo may not have been allocated yet. While here, remove an unnecessary indentation in allocate_cache_info().

Delete the global "num_cache_leaves" and initialize num_leaves on each CPU. init_cache_level() no longer needs to set num_leaves. Also, it never had to set num_levels as it is unnecessary in x86.

However commit e820dbeb6ad1 ("btrfs: convert btrfs_buffered_write() to use folios") changed to use FGP_STABLE to do the writeback wait, but FGP_STABLE is calling folio_wait_stable(), which only calls folio_wait_writeback() if the address space has AS_STABLE_WRITES, which is not set for btrfs inodes. This means we will not wait for the folio writeback at all. [CAUSE] The cause is FGP_STABLE is not waiting for writeback unconditionally, but only for address spaces with AS_STABLE_WRITES, normally such flag is set when the super block has SB_I_STABLE_WRITES flag. Such super block flag is set when the block device has hardware digest support or has internal checksum requirement. I'd argue btrfs should set such super block due to its default data checksum behavior, but it is not set yet, so this means FGP_STABLE flag will have no effect at all. (For NODATASUM inodes, we can skip the waiting in theory but that should be an optimization in the future.) This can lead to data checksum mismatch, as we can modify the folio while it's still under writeback, this will make the contents differ from the contents at submission and checksum calculation. [FIX] Instead of fully relying on FGP_STABLE, manually do the folio writeback waiting, until we set the address space or super flag.

EFI zboot is not a compression library museum, and so the options can be limited to what is likely to be useful in practice: - GZIP is tried and tested, and is still one of the fastest at decompression time, although the compression ratio is not very high; moreover, Fedora is already shipping EFI zboot kernels for arm64 that use GZIP, and QEMU implements direct support for it when booting a kernel without firmware loaded; - ZSTD has a very high compression ratio (although not the highest), and is almost as fast as GZIP at decompression time. Reducing the number of options makes it less of a hassle for other consumers of the EFI zboot format (such as QEMU today, and kexec in the future) to support it transparently without having to carry 7 different decompression libraries.

Fix the warning by moving blk-mq's cpuhp callback registering out of q->sysfs_lock. Add one dedicated global lock for covering registering & unregistering hctx's cpuhp, and it is safe to do so because hctx is guaranteed to be live if our request_queue is live.

The program invokes trie_delete_elem(), which then acquires trie->lock. However, it is possible that another process is invoking trie_update_elem(). trie_update_elem() will acquire trie->lock first, then invoke kmalloc_node(). kmalloc_node() may invoke get_partial_node() and try to acquire &n->list_lock (not necessarily the same lock object). Therefore, lockdep warns about the circular locking dependency. Invoking kmalloc() before acquiring trie->lock could fix the warning. However, since BPF programs call be invoked from any context (e.g., through kprobe/tracepoint/fentry), there may still be lock ordering problems for internal locks in kmalloc() or trie->lock itself. To eliminate these potential lock ordering problems with kmalloc()'s internal locks, replacing kmalloc()/kfree()/kfree_rcu() with equivalent BPF memory allocator APIs that can be invoked in any context. The lock ordering problems with trie->lock (e.g., reentrance) will be handled separately. Three aspects of this change require explanation: 1. Intermediate and leaf nodes are allocated from the same allocator. Since the value size of LPM trie is usually small, using a single alocator reduces the memory overhead of the BPF memory allocator. 2. Leaf nodes are allocated before disabling IRQs. This handles cases where leaf_size is large (e.g., > 4KB - 8) and updates require intermediate node allocation. If leaf nodes were allocated in IRQ-disabled region, the free objects in BPF memory allocator would not be refilled timely and the intermediate node allocation may fail. 3. Paired migrate_{disable|enable}() calls for node alloc and free. The BPF memory allocator uses per-CPU struct internally, these paired calls are necessary to guarantee correctness.

This won't work on 5750X chips that may be using modified RSS profiles. This commit from 2018 has updated the driver to not use RSS profile for HW GRO packets on newer chips: 50f011b63d8c ("bnxt_en: Update RSS setup and GRO-HW logic according to the latest spec.") However, a recent commit to add support for the newest 5760X chip broke the logic. If the GRO packet needs to be re-segmented by the stack, the wrong GSO type will cause the packet to be dropped. Fix it to only use RSS profile to determine GSO type on the oldest 5730X/5740X chips which cannot use the new method and is safe to use the RSS profiles. Also fix the L3/L4 hash type for RX packets by not using the RSS profile for the same reason. Use the ITYPE field in the RX completion to determine L3/L4 hash types correctly.

But net structure might be freed before all the dst callbacks are called. So when dst_destroy() calls later : if (dst->ops->destroy) dst->ops->destroy(dst); dst->ops points to the old net->xfrm.xfrm[46]_dst_ops, which has been freed. See a relevant issue fixed in : ac888d58869b ("net: do not delay dst_entries_add() in dst_release()") A fix is to queue the 'struct net' to be freed after one another cleanup_net() round (and existing

headers/cleanup.h: Remove the if_not_guard() facility Linus noticed that the new if_not_guard() definition is fragile: "This macro generates actively wrong code if it happens to be inside an if-statement or a loop without a block. IOW, code like this: for (iterate-over-something) if_not_guard(a) return -BUSY; looks like will build fine, but will generate completely incorrect code." The reason is that the __if_not_guard() macro is multi-statement, so while most kernel developers expect macros to be simple or at least compound statements - but for __if_not_guard() it is not so: #define __if_not_guard(_name, _id, args...) \ BUILD_BUG_ON(!__is_cond_ptr(_name)); \ CLASS(_name, _id)(args); \ if (!__guard_ptr(_name)(&_id)) To add insult to injury, the placement of the BUILD_BUG_ON() line makes the macro appear to compile fine, but it will generate incorrect code as Linus reported, for example if used within iteration or conditional statements that will use the first statement of a macro as a loop body or conditional statement body. [ I'd also like to note that the original submission by David Lechner did not contain the BUILD_BUG_ON() line, so it was safer than what we ended up committing. Mea culpa. ] It doesn't appear to be possible to turn this macro into a robust single or compound statement that could be used in single statements, due to the necessity to define an auto scope variable with an open scope and the necessity of it having to expand to a partial 'if' statement with no body. Instead of trying to work around this fragility, just remove the construct before it gets used.

The buf (dma cookie) and len stored in this structure are passed to dma_unmap_single() by stmmac_tx_clean(). The DMA API requires that the dma cookie passed to dma_unmap_single() is the same as the value returned from dma_map_single(). However, by moving the assignment later, this is not the case when priv->dma_cap.addr64 > 32 as "des" is offset by proto_hdr_len. This causes problems such as: dwc-eth-dwmac 2490000.ethernet eth0: Tx DMA map failed and with DMA_API_DEBUG enabled: DMA-API: dwc-eth-dwmac 2490000.ethernet: device driver tries to +free DMA memory it has not allocated [device address=0x000000ffffcf65c0] [size=66 bytes] Fix this by maintaining "des" as the original DMA cookie, and use tso_des to pass the offset DMA cookie to stmmac_tso_allocator().

This may happen because there is congestion on the DSA conduit, the switch CPU port or even user port (Qdiscs like taprio may delay packets indefinitely by design). The technical problem is that the kernel, i.e. ocelot_port_add_txtstamp_skb(), runs out of timestamp IDs eventually, because it never detects that packets are lost, and keeps the IDs of the lost packets on hold indefinitely. The manifestation of the issue once the entire timestamp ID range becomes busy looks like this in dmesg: mscc_felix 0000:00:00.5: port 0 delivering skb without TX timestamp mscc_felix 0000:00:00.5: port 1 delivering skb without TX timestamp At the surface level, we need a timeout timer so that the kernel knows a timestamp ID is available again. But there is a deeper problem with the implementation, which is the monotonically increasing ocelot_port->ts_id. In the presence of packet loss, it will be impossible to detect that and reuse one of the holes created in the range of free timestamp IDs. What we actually need is a bitmap of 63 timestamp IDs tracking which one is available. That is able to use up holes caused by packet loss, but also gives us a unique opportunity to not implement an actual timer_list for the timeout timer (very complicated in terms of locking). We could only declare a timestamp ID stale on demand (lazily), aka when there's no other timestamp ID available. There are pros and cons to this approach: the implementation is much more simple than per-packet timers would be, but most of the stale packets would be quasi-leaked - not really leaked, but blocked in driver memory, since this algorithm sees no reason to free them. An improved technique would be to check for stale timestamp IDs every time we allocate a new one. Assuming a constant flux of PTP packets, this avoids stale packets being blocked in memory, but of course, packets lost at the end of the flux are still blocked until the flux resumes (nobody left to kick them out). Since implementing per-packet timers is way too complicated, this should be good enough.

Notice that in this new usage pattern, a non-congested port should basically use timestamp ID 0 all the time, progressing to higher numbers only if there are unacknowledged timestamps in flight. Compare this to the old usage, where the timestamp ID used to monotonically increase modulo OCELOT_MAX_PTP_ID. In terms of implementation, this simplifies the bookkeeping of the ocelot_port :: ts_id and ptp_skbs_in_flight. Since we need to traverse the list of two-step timestampable skbs for each new packet anyway, the information can already be computed and does not need to be stored. Also, ocelot_port->tx_skbs is always accessed under the switch-wide ocelot->ts_id_lock IRQ-unsafe spinlock, so we don't need the skb queue's lock and can use the unlocked primitives safely. This problem was actually detected using the tc-taprio offload, and is causing trouble in TSN scenarios, which Felix (NXP LS1028A / VSC9959) supports but Ocelot (VSC7514) does not. Thus, I've selected the commit to blame as the one adding initial timestamping support for the Felix switch.

Based on some quick experiments on TGL you have to write the register at least ~5 times for the indexed write command to come out ahead. If you write the register less times than that the MMIO write is faster. So it seems my automagic indexed write logic was a bit misguided. Go back to the original approach only use indexed writes for the cases we know will benefit from it (indexed LUT register updates). Currently we shouldn't have any cases where this truly matters (just some rare double writes to the precision LUT index registers), but we will need to switch the legacy LUT updates to write each LUT register twice (to avoid some palette anti-collision logic troubles). This would be close to the worst case for using indexed writes (two writes per register, and 256 separate registers). Using the MMIO write command should shave off around 30% of the execution time compared to using the indexed write command.

The safe time window for performing the LUT update is thus between the undelayed vblank and frame start. Turns out that with low enough CDCLK frequency (DSB execution speed depends on CDCLK) we can exceed that. As we are currently using non-posted writes for the legacy LUT updates, in which case we can hit the far more severe failure mode. The problem is exacerbated by the fact that non-posted writes are much slower than posted writes (~4x it seems). To mititage the problem let's switch to using posted DSB writes for legacy LUT updates (which will involve using the double write approach to avoid other problems with DSB vs. legacy LUT writes). Despite writing each register twice this will in fact make the legacy LUT update faster when compared to the non-posted write approach, making the problem less likely to appear. The failure mode is also less severe. This isn't the 100% solution we need though. That will involve estimating how long the LUT update will take, and pushing frame start and/or delayed vblank forward to guarantee that the update will have finished by the time the pipe prefill starts...

Currently, the FDMA handler is run in a threaded context. For some reason, this kills performance. Admittedly, I did not do a thorough investigation to see exactly what causes the issue, however, I noticed that in the other driver utilizing the same FDMA engine, we run the FDMA handler in hard IRQ context. Fix this performance issue, by running the FDMA handler in hard IRQ context, not deferring any work to a thread. Prior to this change, the RX UDP performance was: Interval Transfer Bitrate Jitter 0.00-10.20 sec 44.6 MBytes 36.7 Mbits/sec 0.027 ms After this change, the rx UDP performance is: Interval Transfer Bitrate Jitter 0.00-9.12 sec 1.01 GBytes 953 Mbits/sec 0.020 ms Fixes: 10615907e9b5 ("net: sparx5: switchdev: adding frame DMA functionality") Signed-off-by: Daniel Machon Signed-off-by: David S.

And commit 43a43faf5376 ("futex: improve user space accesses") messed that up. It went undetected elsewhere, but caused ppc32 to fail early during boot, because the user access had been started with user_read_access_begin(), but then finished off with just a plain "user_access_end()". Note that the address-masking user access helpers don't even have that read-vs-write distinction, so if powerpc ever wants to do address masking tricks, we'll have to do some extra work for it.

Fix the issue by saving the Hyper-V clock counter just before the suspend, and using it to correct the hv_sched_clock_offset in resume. This makes hv tsc page based sched_clock continuous and ensures that post resume, it starts from where it left off during suspend. Override x86_platform.save_sched_clock_state and x86_platform.restore_sched_clock_state routines to correct this as soon as possible. Note: if Invariant TSC is available, the issue doesn't happen because 1) we don't register read_hv_sched_clock_tsc() for sched clock: See commit e5313f1c5404 ("clocksource/drivers/hyper-v: Rework clocksource and sched clock setup"); 2) the common x86 code adjusts TSC similarly: see __restore_processor_state() -> tsc_verify_tsc_adjust(true) and x86_platform.restore_sched_clock_state().

To reproduce the panic consistently, we can add a "ssleep(10)" for KVP in __vmbus_open(), just before the first hv_ringbuffer_init(), and then we unload and reload the driver hv_utils, and run the daemon manually within the 10 seconds. Fix the panic by reordering the steps in util_probe() so the char dev entry used by the KVP or VSS daemon is not created until after vmbus_open() has completed. This reordering prevents the race condition from happening.

This isn't convenient if we want to check the CS timing configuration somewhere else in the code. Wrap the verification of all the chip select's timing configuration into a single function to ease its exportation in upcoming patches. Remove the validity check from aemif_calc_rate(). Also remove the no longer used 'max' input and change the return type to u32. Remove the check of the aemif_calc_rate()'s return value during device-tree parsing as aemif_calc_rate() can't fail anymore.

For instance, currently, in their master branch [1], the latest ones are: Nightly => { vectorcall_abi: #124485, ptr_metadata: #81513, layout_for_ptr: #69835, }, Stable_1_77(77) => { offset_of: #106655 }, Stable_1_73(73) => { thiscall_abi: #42202 }, Stable_1_71(71) => { c_unwind_abi: #106075 }, Stable_1_68(68) => { abi_efiapi: #105795 }, By default, the highest stable release in their list is used, and users are expected to set one if they need to support older Rust versions (e.g. see [2]). Thus, over time, new Rust features are used by default, and at some point, it is likely that `bindgen` will emit Rust code that requires a Rust version higher than our minimum (or perhaps enabling an unstable feature). Currently, there is no problem because the maximum they have, as seen above, is Rust 1.77.0, and our current minimum is Rust 1.78.0. Therefore, set a Rust target explicitly now to prevent going forward in time too much and thus getting potential build failures at some point. Since we also support a minimum `bindgen` version, and since `bindgen` does not support passing unknown Rust target versions, we need to use the list of our minimum `bindgen` version, rather than the latest. So, since `bindgen` 0.65.1 had this list [3], we need to use Rust 1.68.0: /// Rust stable 1.64 /// * `core_ffi_c` ([Tracking issue](https://github.com/rust-lang/rust/issues/94501)) => Stable_1_64 => 1.64; /// Rust stable 1.68 /// * `abi_efiapi` calling convention ([Tracking issue](https://github.com/rust-lang/rust/issues/65815)) => Stable_1_68 => 1.68; /// Nightly rust /// * `thiscall` calling convention ([Tracking issue](https://github.com/rust-lang/rust/issues/42202)) /// * `vectorcall` calling convention (no tracking issue) /// * `c_unwind` calling convention ([Tracking issue](https://github.com/rust-lang/rust/issues/74990)) => Nightly => nightly; ... /// Latest stable release of Rust pub const LATEST_STABLE_RUST: RustTarget = RustTarget::Stable_1_68; Thus add the `--rust-target 1.68` parameter. Add a comment as well explaining this. An alternative would be to use the currently running (i.e. actual) `rustc` and `bindgen` versions to pick a "better" Rust target version. However, that would introduce more moving parts depending on the user setup and is also more complex to implement. Starting with `bindgen` 0.71.0 [4], we will be able to set any future Rust version instead, i.e. we will be able to set here our minimum supported Rust version. Christian implemented it [5] after seeing this patch. Thanks!

Commit b96ed2c97c79 ("virtio_net: move netdev_tx_reset_queue() call before RX napi enable") was not sufficient to eliminate all BQL crash cases for virtio-net. This issue can be reproduced with the latest net-next master by running: `while :; do ip l set DEV down; ip l set DEV up; done` under heavy network TX load from inside the machine. netdev_tx_reset_queue() can actually be dropped from virtnet_open path; the device is not stopped in any case. For BQL core part, it's just like traffic nearly ceases to exist for some period. For stall detector added to BQL, even if virtnet_close could somehow lead to some TX completions delayed for long, followed by virtnet_open, we can just take it as stall as mentioned in commit 6025b9135f7a ("net: dqs: add NIC stall detector based on BQL"). Note also that users can still reset stall_max via sysfs. So, drop netdev_tx_reset_queue() from virtnet_enable_queue_pair(). This eliminates the BQL crashes. As a result, netdev_tx_reset_queue() is now explicitly required in freeze/restore path. This patch adds it to immediately after free_unused_bufs(), following the rule of thumb: netdev_tx_reset_queue() should follow any SKB freeing not followed by netdev_tx_completed_queue(). This seems the most consistent and streamlined approach, and now netdev_tx_reset_queue() runs whenever free_unused_bufs() is done.

Currently, the exception table resides in the regular .text section. Previously, it was placed at the head by relying on the linker receiving arch/openrisc/kernel/head.o as the first object. However, this behavior has changed because sections like .text.{asan,unknown,unlikely,hot} now precede the regular .text section. The .head.text section is intended for entry points requiring special placement. However, in OpenRISC, this section has been misused: instead of the entry points, it contains boot code meant to be discarded after booting. This feature is typically handled by the .init.text section. This commit addresses the issue by replacing the current __HEAD marker with __INIT and re-annotating the entry points with __HEAD. Additionally, it adds __REF to entry.S to suppress the following modpost warning: WARNING: modpost: vmlinux: section mismatch in reference: _tng_kernel_start+0x70 (section: .text) -> _start (section: .init.text) Fixes: 0043ecea2399 ("vmlinux.lds.h: Adjust symbol ordering in text output section") Reported-by: Guenter Roeck Closes: https://lore.kernel.org/all/5e032233-5b65-4ad5-ac50-d2eb6c00171c@roeck-us.net/#t Signed-off-by: Masahiro Yamada Tested-by: Guenter Roeck Reviewed-by: Rong Xu Signed-off-by: Stafford Horne --- arch/openrisc/kernel/entry.S | 2 ++ arch/openrisc/kernel/head.S | 6 ++++-- arch/openrisc/kernel/vmlinux.lds.S | 3 +-- scripts/head-object-list.txt | 1 - 4 files changed, 7 insertions(+), 5 deletions(-) diff --git a/arch/openrisc/kernel/entry.S b/arch/openrisc/kernel/entry.S index 440711d7bf40e..ce6f2b08a35ed 100644 --- a/arch/openrisc/kernel/entry.S +++ b/arch/openrisc/kernel/entry.S @@ -239,6 +239,8 @@ handler: ;\ /* =====================================================[ exceptions] === */ + __REF + /* ---[ 0x100: RESET exception ]----------------------------------------- */ EXCEPTION_ENTRY(_tng_kernel_start) diff --git a/arch/openrisc/kernel/head.S b/arch/openrisc/kernel/head.S index 439e00f81e5dd..ec6d2a7d5b928 100644 --- a/arch/openrisc/kernel/head.S +++ b/arch/openrisc/kernel/head.S @@ -357,6 +357,8 @@ /* =====================================================[ exceptions] === */ + __HEAD + /* ---[ 0x100: RESET exception ]----------------------------------------- */ .org 0x100 /* Jump to .init code at _start which lives in the .head section @@ -506,10 +508,10 @@ _dispatch_do_ipage_fault: /* .text*/ -/* This early stuff belongs in HEAD, but some of the functions below definitely +/* This early stuff belongs in the .init.text section, but some of the functions below definitely * don't... */ - __HEAD + __INIT .global _start _start: /* Init r0 to zero as per spec */ diff --git a/arch/openrisc/kernel/vmlinux.lds.S b/arch/openrisc/kernel/vmlinux.lds.S index bc13060478373..049bff45f6126 100644 --- a/arch/openrisc/kernel/vmlinux.lds.S +++ b/arch/openrisc/kernel/vmlinux.lds.S @@ -50,6 +50,7 @@ SECTIONS .text : AT(ADDR(.text) - LOAD_OFFSET) { _stext = .; + HEAD_TEXT TEXT_TEXT SCHED_TEXT LOCK_TEXT @@ -83,8 +84,6 @@ SECTIONS . = ALIGN(PAGE_SIZE); __init_begin = .; - HEAD_TEXT_SECTION - /* Page aligned */ INIT_TEXT_SECTION(PAGE_SIZE) diff --git a/scripts/head-object-list.txt b/scripts/head-object-list.txt index f12b4a7b8406b..7274dfc65af60 100644 --- a/scripts/head-object-list.txt +++ b/scripts/head-object-list.txt @@ -24,7 +24,6 @@ arch/m68k/kernel/head.o arch/m68k/kernel/sun3-head.o arch/microblaze/kernel/head.o arch/nios2/kernel/head.o -arch/openrisc/kernel/head.o arch/parisc/kernel/head.o arch/powerpc/kernel/head_44x.o arch/powerpc/kernel/head_64.o From c8f8d4344d50d72181207ee73175bba567c25f58 Mon Sep 17 00:00:00 2001 From: Geert Uytterhoeven Date: Thu, 5 Dec 2024 14:04:26 +0100 Subject: [PATCH 0610/1256] openrisc: Fix misalignments in head.S Align all line continuations and (sub)section headers in a consistent way.

Before the commit 5913320eb0b3 ("platform/x86: p2sb: Allow p2sb_bar() calls during PCI device probe"), p2sb_bar() obtained the resources and then called pci_stop_and_remove_bus_device() for clean up. Then the P2SB device disappeared. The commit 5913320eb0b3 introduced the P2SB device resource cache feature in the boot process. During the resource cache, pci_stop_and_remove_bus_device() is called for the P2SB device, then the P2SB device disappears regardless of whether p2sb_bar() is called or not. Such P2SB device disappearance caused a confusion [1]. To avoid the confusion, avoid the pci_stop_and_remove_bus_device() call when the BIOS does not hide the P2SB device. For that purpose, cache the P2SB device resources only if the BIOS hides the P2SB device. Call p2sb_scan_and_cache() only if p2sb_hidden_by_bios is true. This allows removing two branches from p2sb_scan_and_cache(). When p2sb_bar() is called, get the resources from the cache if the P2SB device is hidden. Otherwise, read the resources from the unhidden P2SB device.

However, if this BIO specifies REQ_NOWAIT, the allocation of a request for its execution in blk_mq_submit_bio() may fail after blk_zone_plug_bio() completed, marking the target zone of the BIO as plugged. When this BIO is retried later on, it will be blocked as the zone write plug of the target zone is in a plugged state without any on-going write operation (completion of write operations trigger unplugging of the next write BIOs for a zone). This leads to a BIO that is stuck in a zone write plug and never completes, which results in various issues such as hung tasks. Avoid this problem by always executing REQ_NOWAIT write BIOs using the BIO work of a zone write plug. This ensure that we never block the BIO issuer and can thus safely ignore the REQ_NOWAIT flag when executing the BIO from the zone write plug BIO work. Since such BIO may be the first write BIO issued to a zone with no on-going write, modify disk_zone_wplug_add_bio() to schedule the zone write plug BIO work if the write plug is not already marked with the BLK_ZONE_WPLUG_PLUGGED flag. This scheduling is otherwise not necessary as the completion of the on-going write for the zone will schedule the execution of the next plugged BIOs. blk_zone_wplug_handle_write() is also fixed to better handle zone write plug allocation failures for REQ_NOWAIT BIOs by failing a write BIO using bio_wouldblock_error() instead of bio_io_error().

The first call to blkdev_issue_zeroout() will try to use hardware offload using a REQ_OP_WRITE_ZEROES operation if the device reports a non-zero max_write_zeroes_sectors queue limit. If this operation fails because of the lack of hardware support, blkdev_issue_zeroout() falls back to using a regular write operation with the zero-page as buffer. Currently, such REQ_OP_WRITE_ZEROES failure is automatically handled by the block layer zone write plugging code which will execute a report zones operation to ensure that the write pointer of the target zone of the failed operation has not changed and to "rewind" the zone write pointer offset of the target zone as it was advanced when the write zero operation was submitted. So the REQ_OP_WRITE_ZEROES failure does not cause any issue and blkdev_issue_zeroout() works as expected. However, since the automatic recovery of zone write pointers by the zone write plugging code can potentially cause deadlocks with queue freeze operations, a different recovery must be implemented in preparation for the removal of zone write plugging report zones based recovery. Do this by introducing the new function blk_zone_issue_zeroout(). This function first calls blkdev_issue_zeroout() with the flag BLKDEV_ZERO_NOFALLBACK to intercept failures on the first execution which attempt to use the device hardware offload with the REQ_OP_WRITE_ZEROES operation. If this attempt fails, a report zone operation is issued to restore the zone write pointer offset of the target zone to the correct position and blkdev_issue_zeroout() is called again without the BLKDEV_ZERO_NOFALLBACK flag. The report zones operation performing this recovery is implemented using the helper function disk_zone_sync_wp_offset() which calls the gendisk report_zones file operation with the callback disk_report_zones_cb(). This callback updates the target write pointer offset of the target zone using the new function disk_zone_wplug_sync_wp_offset(). dmz_reclaim_align_wp() is modified to change its call to blkdev_issue_zeroout() to a call to blk_zone_issue_zeroout() without any other change needed as the two functions are functionnally equivalent.

The intent of this is to ensure that the tracking of a zone write pointer is always correct to ensure that the alignment to a zone write pointer of write BIOs can be checked on submission and that we can always correctly emulate zone append operations using regular write BIOs. However, this error recovery scheme introduces a potential deadlock if a device queue freeze is initiated while BIOs are still plugged in a zone write plug and one of these write operation fails. In such case, the disk zone write plug error recovery work is scheduled and executes a report zone. This in turn can result in a request allocation in the underlying driver to issue the report zones command to the device. But with the device queue freeze already started, this allocation will block, preventing the report zone execution and the continuation of the processing of the plugged BIOs. As plugged BIOs hold a queue usage reference, the queue freeze itself will never complete, resulting in a deadlock. Avoid this problem by completely removing from the zone write plugging code the use of report zones operations after a failed write operation, instead relying on the device user to either execute a report zones, reset the zone, finish the zone, or give up writing to the device (which is a fairly common pattern for file systems which degrade to read-only after write failures). This is not an unreasonnable requirement as all well-behaved applications, FSes and device mapper already use report zones to recover from write errors whenever possible by comparing the current position of a zone write pointer with what their assumption about the position is. The changes to remove the automatic error recovery are as follows: - Completely remove the error recovery work and its associated resources (zone write plug list head, disk error list, and disk zone_wplugs_work work struct). This also removes the functions disk_zone_wplug_set_error() and disk_zone_wplug_clear_error(). - Change the BLK_ZONE_WPLUG_ERROR zone write plug flag into BLK_ZONE_WPLUG_NEED_WP_UPDATE. This new flag is set for a zone write plug whenever a write opration targetting the zone of the zone write plug fails. This flag indicates that the zone write pointer offset is not reliable and that it must be updated when the next report zone, reset zone, finish zone or disk revalidation is executed. - Modify blk_zone_write_plug_bio_endio() to set the BLK_ZONE_WPLUG_NEED_WP_UPDATE flag for the target zone of a failed write BIO. - Modify the function disk_zone_wplug_set_wp_offset() to clear this new flag, thus implementing recovery of a correct write pointer offset with the reset (all) zone and finish zone operations. - Modify blkdev_report_zones() to always use the disk_report_zones_cb() callback so that disk_zone_wplug_sync_wp_offset() can be called for any zone marked with the BLK_ZONE_WPLUG_NEED_WP_UPDATE flag. This implements recovery of a correct write pointer offset for zone write plugs marked with BLK_ZONE_WPLUG_NEED_WP_UPDATE and within the range of the report zones operation executed by the user. - Modify blk_revalidate_seq_zone() to call disk_zone_wplug_sync_wp_offset() for all sequential write required zones when a zoned block device is revalidated, thus always resolving any inconsistency between the write pointer offset of zone write plugs and the actual write pointer position of sequential zones.

For example, consider the following program: __attribute__((__noinline__)) long skb_pull_data(struct __sk_buff *sk, __u32 len) { return bpf_skb_pull_data(sk, len); } SEC("tc") int test_invalidate_checks(struct __sk_buff *sk) { int *p = (void *)(long)sk->data; if ((void *)(p + 1) > (void *)(long)sk->data_end) return TCX_DROP; skb_pull_data(sk, 0); *p = 42; return TCX_PASS; } After a call to bpf_skb_pull_data() the pointer 'p' can't be used safely. See function filter.c:bpf_helper_changes_pkt_data() for a list of such helpers. At the moment verifier invalidates packet pointers when processing helper function calls, and does not traverse global sub-programs when processing calls to global sub-programs. This means that calls to helpers done from global sub-programs do not invalidate pointers in the caller state. E.g. the program above is unsafe, but is not rejected by verifier. This commit fixes the omission by computing field bpf_subprog_info->changes_pkt_data for each sub-program before main verification pass. changes_pkt_data should be set if: - subprogram calls helper for which bpf_helper_changes_pkt_data returns true; - subprogram calls a global function, for which bpf_subprog_info->changes_pkt_data should be set. The verifier.c:check_cfg() pass is modified to compute this information. The commit relies on depth first instruction traversal done by check_cfg() and absence of recursive function calls: - check_cfg() would eventually visit every call to subprogram S in a state when S is fully explored; - when S is fully explored: - every direct helper call within S is explored (and thus changes_pkt_data is set if needed); - every call to subprogram S1 called by S was visited with S1 fully explored (and thus S inherits changes_pkt_data from S1). The downside of such approach is that dead code elimination is not taken into account: if a helper call inside global function is dead because of current configuration, verifier would conservatively assume that the call occurs for the purpose of the changes_pkt_data computation.

Hence, conservatively assume that each tail call invalidates packet pointers. Making the change in bpf_helper_changes_pkt_data() automatically makes use of check_cfg() logic that computes 'changes_pkt_data' effect for global sub-programs, such that the following program could be rejected: int tail_call(struct __sk_buff *sk) { bpf_tail_call_static(sk, &jmp_table, 0); return 0; } SEC("tc") int not_safe(struct __sk_buff *sk) { int *p = (void *)(long)sk->data; ... make p valid ... tail_call(sk); *p = 42; /* this is unsafe */ ... } The tc_bpf2bpf.c:subprog_tc() needs change: mark it as a function that can invalidate packet pointers. Otherwise, it can't be freplaced with tailcall_freplace.c:entry_freplace() that does a tail call.

Later, bpf_prog_run_array_uprobe() starts a RCU-trace read-side critical section, but this is too late. It then uses rcu_dereference_check(), but this use of rcu_dereference_check() does not actually dereference anything. Fix it by aligning the semantics to bpf_prog_run_array(): Let the caller provide rcu_read_lock_trace() protection and then load call->prog_array with rcu_dereference_check(). This issue seems to be theoretical: I don't know of any way to reach this code without having handle_swbp() further up the stack, which is already holding a rcu_read_lock_trace() lock, so where we take rcu_read_lock_trace() in __uprobe_perf_func()/bpf_prog_run_array_uprobe() doesn't actually have any effect.

For example, FUSE fetches entries from a daemon using 4KB buffer and stops fetching if entries exceed the buffer. And then an actor of caller, KSMBD, is used to fill the entries from the buffer. Thus, pattern searching on FUSE, files located after the 4KB could not be found and STATUS_NO_SUCH_FILE was returned.

However, the aggregation ID fields in the completion structures on P7 have been redefined from 16 bits to 12 bits. The freed up 4 bits are redefined for part of the metadata such as the VLAN ID. The aggregation ID mask was not modified when adding support for P7 chips. Including the extra 4 bits for the aggregation ID can potentially cause the driver to store or fetch the packet header of GRO/LRO packets in the wrong TPA buffer. It may hit the BUG() condition in __skb_pull() because the SKB contains no valid packet header: kernel BUG at include/linux/skbuff.h:2766!

This can cause problems with Windows-based filesystems as the file's name still exists after deletion until the file is closed, preventing the parent directory from being removed and causing spurious test failures in xfstests due to inability to remove a directory. The symptom looks something like this in the test output: rm: cannot remove '/mnt/scratch/test/p0/d3': Directory not empty rm: cannot remove '/mnt/scratch/test/p1/dc/dae': Directory not empty Fix this by waiting in unlink and rename for any outstanding I/O requests to be completed on the target file before removing that file. Note that this doesn't prevent Linux from trying to start new requests after deletion if it still has the file open locally - something that's perfectly acceptable on a UNIX system. Note also that whilst I've marked this as fixing the commit to make cifs use netfslib, I don't know that it won't occur before that.

The first descriptor could be already marked as completed when processing of next descriptors for the same frame is still in progress. Although only the last descriptor is configured to generate interrupt, completion of the first descriptor could be noticed by the driver when handling interrupt for the previous frame. Currently, driver stores skb in the entry that corresponds to the first descriptor. This results into skb could be unmapped and freed when hardware did not complete the send yet.

It can happen that when rswitch_stop() executes the masking of interrupts from the queues of the port being closed, napi poll for that port is already scheduled or running on a different CPU. When execution of this napi poll completes, it will unmask the interrupts. And unmasked interrupt can fire after rswitch_stop() returns from napi_disable() call. Then, the handler won't mask it, because napi_schedule_prep() will return false, and interrupt storm will happen. This can't be fixed by making rswitch_stop() call napi_disable() before masking interrupts. In this case, the interrupt storm will happen if interrupt fires between napi_disable() and masking. Fix this by checking for priv->opened_ports bit when unmasking interrupts after napi poll. For that to be consistent, move priv->opened_ports changes into spinlock-protected areas, and reorder other operations in rswitch_open() and rswitch_stop() accordingly.

After first calibration, they are freshed to TASDEVICE_REG(0x00, 0x1a, 0x20), TASDEVICE_REG(0x00, 0x16, 0x58)(PLT_FLAG_REG), TASDEVICE_REG(0x00, 0x14, 0x44)(SINEGAIN_REG), and TASDEVICE_REG(0x00, 0x16, 0x64)(SINEGAIN2_REG) via "Calibration Start" kcontrol. In second calibration, the p[j].reg ~ p[j+3].reg have already become tas2781_cali_start_reg. However, p[j+2].reg, TASDEVICE_REG(0x00, 0x14, 0x44)(SINEGAIN_REG), will be freshed to TASDEVICE_REG(0x00, 0x16, 0x64), which is the third register in the input params of the kcontrol. This is why only first calibration can work, the second-time, third-time or more-time calibration always failed without reboot. Of course, if no p[j].reg is in the list of tas2781_cali_start_reg, this stress test can work well.

This is because regex in the perl script for those markers fails to match the new signatures: - EXPORT_SYMBOL_NS(symbol, "ns"); - EXPORT_SYMBOL_NS_GPL(symbol, "ns"); Update the regex so that it matches quoted string.

Remove bt_copy_from_sockptr() and adapt callers to use copy_safe_from_sockptr(). For sco_sock_setsockopt() (case BT_CODEC) use copy_struct_from_sockptr() to scrub parts of uninitialized buffer.

But with "ENDBR64" instruction on x86, offset 4 is treated as function entry. So, X can't be 4 as well. Thus, 8 was used as offset for the test case. On 64-bit powerpc though, any offset <= 16 can be considered function entry depending on build configuration (see arch_kprobe_on_func_entry() for implementation details). So, use `vfs_read+20` to accommodate that scenario too.

Extended type events can only be opened on CPUs that match the type. Before (working): $ perf record --cpu 1 -- true [ perf record: Woken up 1 times to write data ] [ perf record: Captured and wrote 2.385 MB perf.data (7 samples) ] After (not working): $ perf record -C 1 -- true WARNING: A requested CPU in '1' is not supported by PMU 'cpu_atom' (CPUs 16-27) for event 'cycles:P' Error: The sys_perf_event_open() syscall returned with 22 (Invalid argument) for event (cpu_atom/cycles:P/). /bin/dmesg | grep -i perf may provide additional information. (Ignore the warning message, that's expected and not particularly relevant to this issue). This is because perf_cpu_map__intersect() of the user specified CPU (1) and one of the PMU's CPUs (16-27) correctly results in an empty (NULL) CPU map. However for the purposes of opening an event, libperf converts empty CPU maps into an any CPU (-1) which the kernel rejects. Fix it by deleting evsels with empty CPU maps in the specific case where user requested CPU maps are evaluated.

However, the pmd allocation is not using the generic mechanism used by the VMA code (e.g. pmd_alloc()), or the RISC-V specific create_pgd_mapping()/alloc_pmd_late(). Instead, the vmemmap page table code allocates a page, and calls vmemmap_set_pmd(). This results in that the pmd ctor is *not* called, nor would it make sense to do so. Now, when tearing down a vmemmap page table pmd, the cleanup code would unconditionally, and incorrectly call the pmd dtor, which results in a crash (best case).

It turns out that we can't do this, because while the old behavior of ignoring ignorable code points was most definitely wrong, we have case-folding filesystems with on-disk hash values with that wrong behavior. So now you can't look up those names, because they hash to something different. Of course, it's also entirely possible that in the meantime people have created *new* files with the new ("more correct") case folding logic, and reverting will just make other things break. The correct solution is to not do case folding in filesystems, but sadly, people seem to never really understand that. People still see it as a feature, not a bug.

Stabilize rpath.sh On some systems, neighbor discoveries from ns1 for fec0:42::1 (i.e., the martian trap address) would happen at the wrong time and cause false-negative test result.

Also add a few lockdep asserts to make this more explicit. Calling synchronize_rcu() isn't ideal, but fixing this without is hard and way more intrusive.

One way would be to allocate nft_trans_rule objects + one nft_trans_chain object, deactivate the rules + the chain and then defer the freeing to the nft destroy workqueue.

Further experimentation revealed corruption only happens when the last PRP data element aligns to the end of the page boundary. The device appears to treat this as a PRP chain to a new list instead of the data element that it actually is. This implementation is in violation of the spec. Encountering this errata with the Linux driver requires the host request a 128k transfer and coincidently be handed the last small pool dma buffer within a page. The QD1 quirk effectly works around this because the last data PRP always was at a 248 byte offset from the page start, so it never appeared at the end of the page, but comes at the expense of throttling IO and wasting the remainder of the PRP page beyond 256 bytes. Also to note, the MDTS on these devices is small enough that the "large" prp pool can hold enough PRP elements to never reach the end, so that pool is not a problem either. Introduce a new quirk to ensure the small pool is always aligned such that the last PRP element can't appear a the end of the page. This comes at the expense of wasting 256 bytes per small pool page allocated.

And there's nothing special about the Pdelay_Resp packets - they're just regular 68 byte packets. But with this taprio configuration, the switch would refuse to send even the ETH_ZLEN minimum packet size. This should have definitely not been the case. When applying the taprio config, the driver prints: mscc_felix 0000:00:00.5: port 0 tc 0 min gate length 1250 ns not enough for max frame size 1526 at 1000 Mbps, dropping frames over 132 octets including FCS mscc_felix 0000:00:00.5: port 0 tc 1 min gate length 1250 ns not enough for max frame size 1526 at 1000 Mbps, dropping frames over 132 octets including FCS mscc_felix 0000:00:00.5: port 0 tc 2 min gate length 1250 ns not enough for max frame size 1526 at 1000 Mbps, dropping frames over 132 octets including FCS mscc_felix 0000:00:00.5: port 0 tc 3 min gate length 1250 ns not enough for max frame size 1526 at 1000 Mbps, dropping frames over 132 octets including FCS mscc_felix 0000:00:00.5: port 0 tc 4 min gate length 1250 ns not enough for max frame size 1526 at 1000 Mbps, dropping frames over 132 octets including FCS mscc_felix 0000:00:00.5: port 0 tc 5 min gate length 1250 ns not enough for max frame size 1526 at 1000 Mbps, dropping frames over 132 octets including FCS mscc_felix 0000:00:00.5: port 0 tc 6 min gate length 1250 ns not enough for max frame size 1526 at 1000 Mbps, dropping frames over 132 octets including FCS mscc_felix 0000:00:00.5: port 0 tc 7 min gate length 1250 ns not enough for max frame size 1526 at 1000 Mbps, dropping frames over 132 octets including FCS and thus, everything under 132 bytes - ETH_FCS_LEN should have been sent without problems. Yet it's not. For the forwarding path, the configuration is fine, yet packets injected from Linux get stuck with this schedule no matter what. The first hint that the static guard bands are the cause of the problem is that reverting Michael Walle's commit 297c4de6f780 ("net: dsa: felix: re-enable TAS guard band mode") made things work. It must be that the guard bands are calculated incorrectly. I remembered that there is a magic constant in the driver, set to 33 ns for no logical reason other than experimentation, which says "never let the static guard bands get so large as to leave less than this amount of remaining space in the time slot, because the queue system will refuse to schedule packets otherwise, and they will get stuck". I had a hunch that my previous experimentally-determined value was only good for packets coming from the forwarding path, and that the CPU injection path needed more. I came to the new value of 35 ns through binary search, after seeing that with 544 ns (the bit time required to send the Pdelay_Resp packet at gigabit) it works. Again, this is purely experimental, there's no logic and the manual doesn't say anything. The new driver prints for this schedule look like this: mscc_felix 0000:00:00.5: port 0 tc 0 min gate length 1250 ns not enough for max frame size 1526 at 1000 Mbps, dropping frames over 131 octets including FCS mscc_felix 0000:00:00.5: port 0 tc 1 min gate length 1250 ns not enough for max frame size 1526 at 1000 Mbps, dropping frames over 131 octets including FCS mscc_felix 0000:00:00.5: port 0 tc 2 min gate length 1250 ns not enough for max frame size 1526 at 1000 Mbps, dropping frames over 131 octets including FCS mscc_felix 0000:00:00.5: port 0 tc 3 min gate length 1250 ns not enough for max frame size 1526 at 1000 Mbps, dropping frames over 131 octets including FCS mscc_felix 0000:00:00.5: port 0 tc 4 min gate length 1250 ns not enough for max frame size 1526 at 1000 Mbps, dropping frames over 131 octets including FCS mscc_felix 0000:00:00.5: port 0 tc 5 min gate length 1250 ns not enough for max frame size 1526 at 1000 Mbps, dropping frames over 131 octets including FCS mscc_felix 0000:00:00.5: port 0 tc 6 min gate length 1250 ns not enough for max frame size 1526 at 1000 Mbps, dropping frames over 131 octets including FCS mscc_felix 0000:00:00.5: port 0 tc 7 min gate length 1250 ns not enough for max frame size 1526 at 1000 Mbps, dropping frames over 131 octets including FCS So yes, the maximum MTU is now even smaller by 1 byte than before. This is maybe counter-intuitive, but makes more sense with a diagram of one time slot. Before: Gate open Gate close | | v 1250 ns total time slot duration v <----------------------------------------------------> <----><----------------------------------------------> 33 ns 1217 ns static guard band useful Gate open Gate close | | v 1250 ns total time slot duration v <----------------------------------------------------> <-----><---------------------------------------------> 35 ns 1215 ns static guard band useful The static guard band implemented by this switch hardware directly determines the maximum allowable MTU for that traffic class. The larger it is, the earlier the switch will stop scheduling frames for transmission, because otherwise they might overrun the gate close time (and avoiding that is the entire purpose of Michael's patch). So, we now have guard bands smaller by 2 ns, thus, in this particular case, we lose a byte of the maximum MTU.

This function updates 'qlen' and the backlog statistics of netem, but netem does not account for changes made by a child qdisc. 'qlen' then indicates the wrong number of packets in the tfifo. If a child qdisc creates new SKBs during enqueue and informs its parent about this, netem's 'qlen' value is increased. When netem dequeues the newly created SKBs from the child, the 'qlen' in netem is not updated. If 'qlen' reaches the configured sch->limit, the enqueue function stops working, even though the tfifo is not full. Reproduce the bug: Ensure that the sender machine has GSO enabled. Configure netem as root qdisc and tbf as its child on the outgoing interface of the machine as follows: $ tc qdisc add dev root handle 1: netem delay 100ms limit 100 $ tc qdisc add dev parent 1:0 tbf rate 50Mbit burst 1542 latency 50ms Send bulk TCP traffic out via this interface, e.g., by running an iPerf3 client on the machine. Check the qdisc statistics: $ tc -s qdisc show dev Statistics after 10s of iPerf3 TCP test before the fix (note that netem's backlog > limit, netem stopped accepting packets): qdisc netem 1: root refcnt 2 limit 1000 delay 100ms Sent 2767766 bytes 1848 pkt (dropped 652, overlimits 0 requeues 0) backlog 4294528236b 1155p requeues 0 qdisc tbf 10: parent 1:1 rate 50Mbit burst 1537b lat 50ms Sent 2767766 bytes 1848 pkt (dropped 327, overlimits 7601 requeues 0) backlog 0b 0p requeues 0 Statistics after the fix: qdisc netem 1: root refcnt 2 limit 1000 delay 100ms Sent 37766372 bytes 24974 pkt (dropped 9, overlimits 0 requeues 0) backlog 0b 0p requeues 0 qdisc tbf 10: parent 1:1 rate 50Mbit burst 1537b lat 50ms Sent 37766372 bytes 24974 pkt (dropped 327, overlimits 96017 requeues 0) backlog 0b 0p requeues 0 tbf segments the GSO SKBs (tbf_segment) and updates the netem's 'qlen'. The interface fully stops transferring packets and "locks". In this case, the child qdisc and tfifo are empty, but 'qlen' indicates the tfifo is at its limit and no more packets are accepted. This patch adds a counter for the entries in the tfifo. Netem's 'qlen' is only decreased when a packet is returned by its dequeue function, and not during enqueuing into the child qdisc. External updates to 'qlen' are thus accounted for and only the behavior of the backlog statistics changes. As in other qdiscs, 'qlen' then keeps track of how many packets are held in netem and all of its children. As before, sch->limit remains as the maximum number of packets in the tfifo. The same applies to netem's backlog statistics.

E.g. Biju reported a measured bus speed of 450 kHz instead of the expected maximum of 400 kHz on RZ/G2L. The initial calculation of the bus period uses DIV_ROUND_UP(), to make sure the actual bus speed never becomes faster than the requested bus speed. However, the subsequent division-by-two steps do not use round-up, which may lead to a too-small period, hence a too-fast and possible out-of-spec bus speed. E.g. on RZ/Five, requesting a bus speed of 100 resp. 400 kHz will yield too-fast target bus speeds of 100806 resp. 403226 Hz instead of 97656 resp. 390625 Hz. Fix this by using DIV_ROUND_UP() in the subsequent divisions, too. Tested on RZ/A1H, RZ/A2M, and RZ/Five.

The PCM part of the voice setting is used for offload mode through PCM chipset port. This commits add support for mSBC 16 bits offloading, i.e. audio data not transported over HCI. The BCM4349B1 supports 16 bits transparent data on its I2S port. If BT_VOICE_TRANSPARENT is used when accepting a SCO connection, this gives only garbage audio while using BT_VOICE_TRANSPARENT_16BIT gives correct audio.

The commit provided code to apply "Module 6: Certain PHY registers must be written as pairs instead of singly" errata for KSZ9477 as this chip for certain PHY registers (0xN120 to 0xN13F, N=1,2,3,4,5) must be accessed as 32 bit words instead of 16 or 8 bit access. Otherwise, adjacent registers (no matter if reserved or not) are overwritten with 0x0. Without this patch some registers (e.g. 0x113c or 0x1134) required for 32 bit access are out of valid regmap ranges. As a result, following error is observed and KSZ9896 is not properly configured: ksz-switch spi1.0: can't rmw 32bit reg 0x113c: -EIO ksz-switch spi1.0: can't rmw 32bit reg 0x1134: -EIO ksz-switch spi1.0 lan1 (uninitialized): failed to connect to PHY: -EIO ksz-switch spi1.0 lan1 (uninitialized): error -5 setting up PHY for tree 0, switch 0, port 0 The solution is to modify regmap_reg_range to allow accesses with 4 bytes boundaries.

This happens because the stacktrace code encounters an exception boundary where the LR was not live at the time of the exception, but the LR happens to contain return_to_handler(); either because the task recently returned there, or due to unfortunate usage of the LR at a scratch register. In such cases attempts to recover the return address via ftrace_graph_ret_addr() may fail, triggering the WARN_ON_ONCE() above and aborting the unwind (hence the stacktrace terminating after reporting the PC at the time of the exception). Handling unreliable LR values in these cases is likely to require some larger rework, so for the moment avoid this problem by restoring the old behaviour of skipping the LR at exception boundaries, which the stacktrace code did prior to commit: c2c6b27b5aa14fa2 ("arm64: stacktrace: unwind exception boundaries") This commit is effectively a partial revert, keeping the structures and logic to explicitly identify exception boundaries while still skipping reporting of the LR. The logic to explicitly identify exception boundaries is still useful for general robustness and as a building block for future support for RELIABLE_STACKTRACE.

The conditions shouldn't be triggered when unwinding the current task, but it is possible to trigger these when unwinding another task which is not blocked, as the stack of that task is concurrently modified. Kent reports that these warnings can be triggered while running filesystem tests on bcachefs, which calls the stacktrace code directly. To produce a meaningful stacktrace of another task, the task in question should be blocked, but the stacktrace code is expected to be robust to cases where it is not blocked. Note that this is purely about not unuduly scaring the user and/or crashing the kernel; stacktraces in such cases are meaningless and may leak kernel secrets from the stack of the task being unwound. Ideally we'd pin the task in a blocked state during the unwind, as we do for /proc/${PID}/wchan since commit: 42a20f86dc19f928 ("sched: Add wrapper for get_wchan() to keep task blocked") ... but a bunch of places don't do that, notably /proc/${PID}/stack, where we don't pin the task in a blocked state, but do restrict the output to privileged users since commit: f8a00cef17206ecd ("proc: restrict kernel stack dumps to root") ... and so it's possible to trigger these warnings accidentally, e.g. by reading /proc/*/stack (as root): | for n in $(seq 1 10); do | while true; do cat /proc/*/stack > /dev/null 2>&1; done & | done | ------------[ cut here ]------------ | WARNING: CPU: 3 PID: 166 at arch/arm64/kernel/stacktrace.c:207 arch_stack_walk+0x1c8/0x370 | Modules linked in: | CPU: 3 UID: 0 PID: 166 Comm: cat Not tainted 6.13.0-rc2-00003-g3dafa7a7925d #2 | Hardware name: linux,dummy-virt (DT) | pstate: 81400005 (Nzcv daif +PAN -UAO -TCO +DIT -SSBS BTYPE=--) | pc : arch_stack_walk+0x1c8/0x370 | lr : arch_stack_walk+0x1b0/0x370 | sp : ffff800080773890 | x29: ffff800080773930 x28: fff0000005c44500 x27: fff00000058fa038 | x26: 000000007ffff000 x25: 0000000000000000 x24: 0000000000000000 | x23: ffffa35a8d9600ec x22: 0000000000000000 x21: fff00000043a33c0 | x20: ffff800080773970 x19: ffffa35a8d960168 x18: 0000000000000000 | x17: 0000000000000000 x16: 0000000000000000 x15: 0000000000000000 | x14: 0000000000000000 x13: 0000000000000000 x12: 0000000000000000 | x11: 0000000000000000 x10: 0000000000000000 x9 : 0000000000000000 | x8 : ffff8000807738e0 x7 : ffff8000806e3800 x6 : ffff8000806e3818 | x5 : ffff800080773920 x4 : ffff8000806e4000 x3 : ffff8000807738e0 | x2 : 0000000000000018 x1 : ffff8000806e3800 x0 : 0000000000000000 | Call trace: | arch_stack_walk+0x1c8/0x370 (P) | stack_trace_save_tsk+0x8c/0x108 | proc_pid_stack+0xb0/0x134 | proc_single_show+0x60/0x120 | seq_read_iter+0x104/0x438 | seq_read+0xf8/0x140 | vfs_read+0xc4/0x31c | ksys_read+0x70/0x108 | __arm64_sys_read+0x1c/0x28 | invoke_syscall+0x48/0x104 | el0_svc_common.constprop.0+0x40/0xe0 | do_el0_svc+0x1c/0x28 | el0_svc+0x30/0xcc | el0t_64_sync_handler+0x10c/0x138 | el0t_64_sync+0x198/0x19c | ---[ end trace 0000000000000000 ]--- Fix this by only warning when unwinding the current task.

The code falls back to btf_ctx_access to ensure correctness and obtaining the types of pointers. Ensure that the size of the access is correctly checked to be 8 bytes, otherwise the verifier thinks the narrow load obtained a trusted BTF pointer and will permit loads/stores as it sees fit. Perform the check on size after we've verified that the load is for a pointer field, as for scalar values narrow loads are fine. Access to structs passed as arguments to a BPF program are also treated as scalars, therefore no adjustment is needed in their case. Existing verifier selftests are broken by this change, but because they were incorrect. Verifier tests for d_path were performing narrow load into context to obtain path pointer, had this program actually run it would cause a crash. The same holds for verifier_btf_ctx_access tests.

Wong" Date: Mon, 2 Dec 2024 10:57:24 -0800 Subject: [PATCH 0763/1256] xfs: fix off-by-one error in fsmap's end_daddr usage In commit ca6448aed4f10a, we created an "end_daddr" variable to fix fsmap reporting when the end of the range requested falls in the middle of an unknown (aka free on the rmapbt) region. Unfortunately, I didn't notice that the the code sets end_daddr to the last sector of the device but then uses that quantity to compute the length of the synthesized mapping. Zizhi Wo later observed that when end_daddr isn't set, we still don't report the last fsblock on a device because in that case (aka when info->last is true), the info->high mapping that we pass to xfs_getfsmap_group_helper has a startblock that points to the last fsblock. This is also wrong because the code uses startblock to compute the length of the synthesized mapping. Fix the second problem by setting end_daddr unconditionally, and fix the first problem by setting start_daddr to one past the end of the range to query.

Even with a 64k fsblock size, that maps out to a bmbt containing more than 2^32 blocks. Therefore, this predicate must return a u64 count to avoid an integer wraparound that will cause scrub to do the wrong thing. It's unlikely that any such filesystem currently exists, because the incore bmbt would consume more than 64GB of kernel memory on its own, and so far nobody except me has driven a filesystem that far, judging from the lack of complaints.

Wong" Date: Mon, 2 Dec 2024 10:57:27 -0800 Subject: [PATCH 0767/1256] xfs: don't drop errno values when we fail to ficlone the entire range Way back when we first implemented FICLONE for XFS, life was simple -- either the the entire remapping completed, or something happened and we had to return an errno explaining what happened. Neither of those ioctls support returning partial results, so it's all or nothing. Then things got complicated when copy_file_range came along, because it actually can return the number of bytes copied, so commit 3f68c1f562f1e4 tried to make it so that we could return a partial result if the REMAP_FILE_CAN_SHORTEN flag is set. This is also how FIDEDUPERANGE can indicate that the kernel performed a partial deduplication. Unfortunately, the logic is wrong if an error stops the remapping and CAN_SHORTEN is not set. Because those callers cannot return partial results, it is an error for ->remap_file_range to return a positive quantity that is less than the @len passed in. Implementations really should be returning a negative errno in this case, because that's what btrfs (which introduced FICLONE{,RANGE}) did. Therefore, ->remap_range implementations cannot silently drop an errno that they might have when the number of bytes remapped is less than the number of bytes requested and CAN_SHORTEN is not set. Found by running generic/562 on a 64k fsblock filesystem and wondering why it reported corrupt files.

Wong" Date: Mon, 2 Dec 2024 10:57:27 -0800 Subject: [PATCH 0768/1256] xfs: separate healthy clearing mask during repair In commit d9041681dd2f53 we introduced some XFS_SICK_*ZAPPED flags so that the inode record repair code could clean up a damaged inode record enough to iget the inode but still be able to remember that the higher level repair code needs to be called. As part of that, we introduced a xchk_mark_healthy_if_clean helper that is supposed to cause the ZAPPED state to be removed if that higher level metadata actually checks out. This was done by setting additional bits in sick_mask hoping that xchk_update_health will clear all those bits after a healthy scrub. Unfortunately, that's not quite what sick_mask means -- bits in that mask are indeed cleared if the metadata is healthy, but they're set if the metadata is NOT healthy. fsck is only intended to set the ZAPPED bits explicitly. If something else sets the CORRUPT/XCORRUPT state after the xchk_mark_healthy_if_clean call, we end up marking the metadata zapped. This can happen if the following sequence happens: 1. Scrub runs, discovers that the metadata is fine but could be optimized and calls xchk_mark_healthy_if_clean on a ZAPPED flag. That causes the ZAPPED flag to be set in sick_mask because the metadata is not CORRUPT or XCORRUPT. 2. Repair runs to optimize the metadata. 3. Some other metadata used for cross-referencing in (1) becomes corrupt. 4. Post-repair scrub runs, but this time it sets CORRUPT or XCORRUPT due to the events in (3). 5. Now the xchk_health_update sets the ZAPPED flag on the metadata we just repaired. This is not the correct state.

I observed the following sequence of events: 1. Initiate a repair of the parent pointers for the /quota/user file. This is the secret file containing user quota data. 2. The pptr repair thread creates a temporary file and begins staging parent pointers in the ondisk metadata in preparation for an exchange-range to commit the new pptr data. 3. At the same time, initiate a repair of the /quota directory itself. 4. The dir repair thread finds the temporary file from (2), scans it for parent pointers, and stages a dirent in its own temporary dir in preparation to commit the fixed directory. 5. The parent pointer repair completes and frees the temporary file. 6. The dir repair commits the new directory and scans it again. It finds the dirent that points to the old temporary file in (2) and marks the directory corrupt. Oops! Repair code must never scan the temporary files that other repair functions create to stage new metadata. They're not supposed to do that, but the predicate function xrep_is_tempfile is incorrect because it assumes that any XFS_DIFLAG2_METADATA file cannot ever be a temporary file, but xrep_tempfile_adjust_directory_tree creates exactly that. Fix this by setting the IRECOVERY flag on temporary metadata directory inodes and using that to correct the predicate. Repair code is supposed to erase all the data in temporary files before releasing them, so it's ok if a thread scans the temporary file after we drop IRECOVERY.

If the allocation request is for a file range that's adjacent to an existing mapping, it will then change bno_hint to the blkno hint in the bmalloca structure. In other words, bno_hint is either a rt block number, or it's all 1s. Unfortunately, commit ec12f97f1b8a8f didn't take the NULLRTBLOCK state into account, which means that it tries to translate that into a realtime extent number. We then end up with an obnoxiously high rtx number and pointlessly feed that to the near allocator. This often fails and falls back to the by-size allocator. Seeing as we had no locality hint anyway, this is a waste of time. Fix the code to detect a lack of bno_hint correctly. This was detected by running xfs/009 with metadir enabled and a 28k rt extent size. Cc: # v6.12 Fixes: ec12f97f1b8a8f ("xfs: make the rtalloc start hint a xfs_rtblock_t") Signed-off-by: "Darrick J.

The solution was to detect this situation and update the in-core key value that we pass up to the caller so that the caller will (eventually) add the new block to the parent level of the tree with the correct key. However, I missed a subtlety about the way inode-rooted btrees work. If the full block was a maximally sized inode root block, we'll solve that fullness by moving the root block's records to a new block, resizing the root block, and updating the root to point to the new block. We don't pass a pointer to the new block to the caller because that work has already been done. The new record will /always/ land in the new block, so in this case we need to use xfs_btree_update_keys to update the keys. This bug can theoretically manifest itself in the very rare case that we split a bmbt root block and the new record lands in the very first slot of the new block, though I've never managed to trigger it in practice. However, it is very easy to reproduce by running generic/522 with the realtime rmapbt patchset if rtinherit=1.

Unfortunately, after the finish_noroll loop we forgot to run precommits on txC. That was fixed by adding the second precommit call. Unfortunately, none of us remembered that xfs_defer_finish_noroll calls __xfs_trans_commit a second time to commit tx0 before finishing work A in txA and committing that.

However, it doesn't make sense to run precommits twice. Fix this situation by only running precommits after finish_noroll.

In other words, there's a nested function call (albeit with slightly different arguments) that has caused minor amounts of confusion in the past. There's no reason to keep this around, since there's only one place where we actually want the xfs_defer_finish_noroll, and that is in the top level xfs_trans_commit call. This also reduces stack usage a little bit. Signed-off-by: "Darrick J.

What's happening here is that the XFS AIL is trying to write a disk quota update back into the filesystem, but for that it needs to read the ondisk buffer for the dquot. The buffer is not in memory anymore, probably because it was evicted. Regardless, the buffer cache tries to allocate a new buffer, but those allocations are NOFAIL. The AIL thread has marked itself PF_MEMALLOC (aka noreclaim) since commit 43ff2122e6492b ("xfs: on-stack delayed write buffer lists") presumably because reclaim can push on XFS to push on the AIL. An easy way to fix this probably would have been to drop the NOFAIL flag from the xfs_buf allocation and open code a retry loop, but then there's still the problem that for bs>ps filesystems, the buffer itself could require up to 64k worth of pages. Inode items had similar behavior (multi-page cluster buffers that we don't want to allocate in the AIL) which we solved by making transaction precommit attach the inode cluster buffers to the dirty log item. Let's solve the dquot problem in the same way. So: Make a real precommit handler to read the dquot buffer and attach it to the log item; pass it to dqflush in the push method; and have the iodone function detach the buffer once we've flushed everything. Add a state flag to the log item to track when a thread has entered the precommit -> push mechanism to skip the detaching if it turns out that the dquot is very busy, as we don't hold the dquot lock between log item commit and AIL push). Reading and attaching the dquot buffer in the precommit hook is inspired by the work done for inode cluster buffers some time ago.

Wong" Date: Mon, 2 Dec 2024 10:57:39 -0800 Subject: [PATCH 0784/1256] xfs: fix sb_spino_align checks for large fsblock sizes For a sparse inodes filesystem, mkfs.xfs computes the values of sb_spino_align and sb_inoalignmt with the following code: int cluster_size = XFS_INODE_BIG_CLUSTER_SIZE; if (cfg->sb_feat.crcs_enabled) cluster_size *= cfg->inodesize / XFS_DINODE_MIN_SIZE; sbp->sb_spino_align = cluster_size >> cfg->blocklog; sbp->sb_inoalignmt = XFS_INODES_PER_CHUNK * cfg->inodesize >> cfg->blocklog; On a V5 filesystem with 64k fsblocks and 512 byte inodes, this results in cluster_size = 8192 * (512 / 256) = 16384. As a result, sb_spino_align and sb_inoalignmt are both set to zero. Unfortunately, this trips the new sb_spino_align check that was just added to xfs_validate_sb_common, and the mkfs fails: # mkfs.xfs -f -b size=64k, /dev/sda meta-data=/dev/sda isize=512 agcount=4, agsize=81136 blks = sectsz=512 attr=2, projid32bit=1 = crc=1 finobt=1, sparse=1, rmapbt=1 = reflink=1 bigtime=1 inobtcount=1 nrext64=1 = exchange=0 metadir=0 data = bsize=65536 blocks=324544, imaxpct=25 = sunit=0 swidth=0 blks naming =version 2 bsize=65536 ascii-ci=0, ftype=1, parent=0 log =internal log bsize=65536 blocks=5006, version=2 = sectsz=512 sunit=0 blks, lazy-count=1 realtime =none extsz=65536 blocks=0, rtextents=0 = rgcount=0 rgsize=0 extents Discarding blocks...Sparse inode alignment (0) is invalid.

Don't move the repair tempfile to the metadir namespace if this is not true; this will cause the inode verifiers to trip. xrep_tempfile_adjust_directory_tree opportunistically moves sc->tempip from the regular directory tree to the metadata directory tree if sc->ip is part of the metadata directory tree. However, the scrub setup functions grab sc->ip and create sc->tempip before we actually get around to checking if the file mode is the right type for the scrubber. IOWs, you can invoke the symlink scrubber with the file handle of a subdirectory in the metadir. xrep_setup_symlink will create a temporary symlink file, xrep_tempfile_adjust_directory_tree will foolishly try to set the METADATA flag on the temp symlink, which trips the inode verifier in the inode item precommit, which shuts down the filesystem when expensive checks are turned on. If they're /not/ turned on, then xchk_symlink will return ENOENT when it sees that it's been passed a symlink, but the invalid inode could still get flushed to disk. We don't want that.

The dlserver throttling and replenish logic gets confused and can lead to double enqueue of dlserver. Double enqueue of dlserver could happend due to couple of reasons: Case 1 ------ Delayed dequeue feature[1] can cause dlserver being stopped during a pick initiated by dlserver: __pick_next_task pick_task_dl -> server_pick_task pick_task_fair pick_next_entity (if (sched_delayed)) dequeue_entities dl_server_stop server_pick_task goes ahead with update_curr_dl_se without knowing that dlserver is dequeued and this confuses the logic and may lead to unintended enqueue while the server is stopped. Case 2 ------ A race condition between a task dequeue on one cpu and same task's enqueue on this cpu by a remote cpu while the lock is released causing dlserver double enqueue. One cpu would be in the schedule() and releasing RQ-lock: current->state = TASK_INTERRUPTIBLE(); schedule(); deactivate_task() dl_stop_server(); pick_next_task() pick_next_task_fair() sched_balance_newidle() rq_unlock(this_rq) at which point another CPU can take our RQ-lock and do: try_to_wake_up() ttwu_queue() rq_lock() ... activate_task() dl_server_start() --> first enqueue wakeup_preempt() := check_preempt_wakeup_fair() update_curr() update_curr_task() if (current->dl_server) dl_server_update() enqueue_dl_entity() --> second enqueue This bug was not apparent as the enqueue in dl_server_start doesn't usually happen because of the defer logic. But as a side effect of the first case(dequeue during dlserver pick), dl_throttled and dl_yield will be set and this causes the time accounting of dlserver to messup and then leading to a enqueue in dl_server_start. Have an explicit flag representing the status of dlserver to avoid the confusion. This is set in dl_server_start and reset in dlserver_stop.

This is unfortunate as it is too late to deliver a SIGSEGV: if that SIGSEGV is handled, the subsequent sigreturn will end up returning to the original handler, which is not the intention (since we failed to deliver that signal). Make sure this does not happen by calling gcs_signal_entry() at the very beginning of setup_return(), and add a comment just after to discourage error cases being introduced from that point onwards. While at it, also take care of copy_siginfo_to_user(): since it may fail, we shouldn't be calling it after setup_return() either. Call it before setup_return() instead, and move the setting of X1/X2 inside setup_return() where it belongs (after the "point of no failure"). Background: the first part of setup_rt_frame(), including setup_sigframe(), has no impact on the execution of the interrupted thread. The signal frame is written to the stack, but the stack pointer remains unchanged. Failure at this stage can be recovered by a SIGSEGV handler, and sigreturn will restore the original context, at the point where the original signal occurred. On the other hand, once setup_return() has updated registers including SP, the thread's control flow has been modified and we must deliver the original signal.

This can occur when an exception happens and the process terminates before the device driver stops DMA and calls the iommu driver to unbind the PASID. There's no need to drain the PRQ in the mm release path. Instead, the PRQ will be drained in the SVA unbind path. Unfortunately, commit c43e1ccdebf2 ("iommu/vt-d: Drain PRQs when domain removed from RID") changed this behavior by unconditionally draining the PRQ in intel_pasid_tear_down_entry(). This can lead to a potential sleeping-in-atomic-context issue. Smatch static checker warning: drivers/iommu/intel/prq.c:95 intel_iommu_drain_pasid_prq() warn: sleeping in atomic context To avoid this issue, prevent draining the PRQ in the SVA mm release path and restore the previous behavior.

This has some pretty bad effects on the way priorities are handled, and results in a dead machine if booting with pseudo-NMI enabled (irqchip.gicv3_pseudo_nmi=1) if the kernel contains 18fdb6348c480 ("arm64: irqchip/gic-v3: Select priorities at boot time"), which relies on the priorities being programmed using the NS view. Let's restore some sanity by going one step further and disable security altogether in this case. This is not any worse, and puts us in a mode where priorities actually make some sense.

The offset, size, and metadata for CPUID.0xD.[1..n] sub-leaves does not depend on XCR0 or XSS values, i.e. is constant for a given CPU, and thus can be cached during module load. On Intel's Emerald Rapids, CPUID is *wildly* expensive, to the point where recomputing XSAVE offsets and sizes results in a 4x increase in latency of nested VM-Enter and VM-Exit (nested transitions can trigger xstate_required_size() multiple times per transition), relative to using cached values. The issue is easily visible by running `perf top` while triggering nested transitions: kvm_update_cpuid_runtime() shows up at a whopping 50%. As measured via RDTSC from L2 (using KVM-Unit-Test's CPUID VM-Exit test and a slightly modified L1 KVM to handle CPUID in the fastpath), a nested roundtrip to emulate CPUID on Skylake (SKX), Icelake (ICX), and Emerald Rapids (EMR) takes: SKX 11650 ICX 22350 EMR 28850 Using cached values, the latency drops to: SKX 6850 ICX 9000 EMR 7900 The underlying issue is that CPUID itself is slow on ICX, and comically slow on EMR. The problem is exacerbated on CPUs which support XSAVES and/or XSAVEC, as KVM invokes xstate_required_size() twice on each runtime CPUID update, and because there are more supported XSAVE features (CPUID for supported XSAVE feature sub-leafs is significantly slower). SKX: CPUID.0xD.2 = 348 cycles CPUID.0xD.3 = 400 cycles CPUID.0xD.4 = 276 cycles CPUID.0xD.5 = 236 cycles EMR: CPUID.0xD.2 = 1138 cycles CPUID.0xD.3 = 1362 cycles CPUID.0xD.4 = 1068 cycles CPUID.0xD.5 = 910 cycles CPUID.0xD.6 = 914 cycles CPUID.0xD.7 = 1350 cycles CPUID.0xD.8 = 734 cycles CPUID.0xD.9 = 766 cycles CPUID.0xD.10 = 732 cycles CPUID.0xD.11 = 718 cycles CPUID.0xD.12 = 734 cycles CPUID.0xD.13 = 1700 cycles CPUID.0xD.14 = 1126 cycles CPUID.0xD.15 = 898 cycles CPUID.0xD.16 = 716 cycles CPUID.0xD.17 = 748 cycles CPUID.0xD.18 = 776 cycles Note, updating runtime CPUID information multiple times per nested transition is itself a flaw, especially since CPUID is a mandotory intercept on both Intel and AMD. E.g. KVM doesn't need to ensure emulated CPUID state is up-to-date while running L2. That flaw will be fixed in a future patch, as deferring runtime CPUID updates is more subtle than it appears at first glance, the benefits aren't super critical to have once the XSAVE issue is resolved, and caching CPUID output is desirable even if KVM's updates are deferred.

The patch was well-intended and meant to be as a stop-gap fixing branch prediction when the pointer may actually be NULL at runtime. Eventually, it was supposed to be replaced by an automated script or compiler pass detecting possibly NULL arguments and marking them accordingly. However, it caused two main issues observed for production programs and failed to preserve backwards compatibility. First, programs relied on the verifier not exploring == NULL branch when pointer is not NULL, thus they started failing with a 'dereference of scalar' error. Next, allowing raw_tp arguments to be modified surfaced the warning in the verifier that warns against reg->off when PTR_MAYBE_NULL is set. More information, context, and discusson on both problems is available in [0]. Overall, this approach had several shortcomings, and the fixes would further complicate the verifier's logic, and the entire masking scheme would have to be removed eventually anyway. Hence, revert the patch in preparation of a better fix avoiding these issues to replace this commit.

However, in certain cases, a raw tracepoint argument may end up being NULL. More context about this issue is available in [0]. Thus, there is a discrepancy between the reality, that raw_tp arguments can actually be NULL, and the verifier's knowledge, that they are never NULL, causing explicit NULL check branch to be dead code eliminated. A previous attempt [1], i.e. the second fixed commit, was made to simulate symbolic execution as if in most accesses, the argument is a non-NULL raw_tp, except for conditional jumps. This tried to suppress branch prediction while preserving compatibility, but surfaced issues with production programs that were difficult to solve without increasing verifier complexity. A more complete discussion of issues and fixes is available at [2]. Fix this by maintaining an explicit list of tracepoints where the arguments are known to be NULL, and mark the positional arguments as PTR_MAYBE_NULL. Additionally, capture the tracepoints where arguments are known to be ERR_PTR, and mark these arguments as scalar values to prevent potential dereference. Each hex digit is used to encode NULL-ness (0x1) or ERR_PTR-ness (0x2), shifted by the zero-indexed argument number x 4. This can be represented as follows: 1st arg: 0x1 2nd arg: 0x10 3rd arg: 0x100 ... and so on (likewise for ERR_PTR case). In the future, an automated pass will be used to produce such a list, or insert __nullable annotations automatically for tracepoints. Each compilation unit will be analyzed and results will be collated to find whether a tracepoint pointer is definitely not null, maybe null, or an unknown state where verifier conservatively marks it PTR_MAYBE_NULL. A proof of concept of this tool from Eduard is available at [3]. Note that in case we don't find a specification in the raw_tp_null_args array and the tracepoint belongs to a kernel module, we will conservatively mark the arguments as PTR_MAYBE_NULL. This is because unlike for in-tree modules, out-of-tree module tracepoints may pass NULL freely to the tracepoint. We don't protect against such tracepoints passing ERR_PTR (which is uncommon anyway), lest we mark all such arguments as SCALAR_VALUE. While we are it, let's adjust the test raw_tp_null to not perform dereference of the skb->mark, as that won't be allowed anymore, and make it more robust by using inline assembly to test the dead code elimination behavior, which should still stay the same.

The problem is that reaching the limit causes ksmbd to close the socket, and the client has no indication that it should have slowed down. This behaviour can be reproduced by setting "smb2 max credits = 128" (or lower), and transferring a large file (25GB). smbclient fails as below: $ smbclient //192.168.1.254/testshare -U user%pass smb: \> put file.bin cli_push returned NT_STATUS_USER_SESSION_DELETED putting file file.bin as \file.bin smb2cli_req_compound_submit: Insufficient credits. 0 available, 1 needed NT_STATUS_INTERNAL_ERROR closing remote file \file.bin smb: \> smb2cli_req_compound_submit: Insufficient credits. 0 available, 1 needed Windows clients fail with 0x8007003b (with smaller files even). Fix this by delaying reading from the socket until there's room to allocate a request. This effectively applies backpressure on the client, so the transfer completes, albeit at a slower rate.

However, the host router must be powered on for this to work. Aaron reported that there are a couple of cases where this will not work with the current code: - Booting with USB-C monitor plugged in. - Plugging in USB-C monitor when the host router is in sleep state (runtime suspended). - Plugging in USB-C device while the system is in system sleep state. In all these cases once the host router is runtime suspended the picture on the connected USB-C display disappears too. This is certainly not what the user expected. For this reason improve the redrive mode handling to keep the host router from runtime suspending when detect that any of the above cases is happening.

The warning triggers from the legacy fallback stub. That warning is bogus as the PCI/MSI layer knows whether a PCI/MSI parent domain is associated with the device or not. There is a check for MSI-X, which has a legacy assumption. But that legacy fallback assumption is only valid when legacy support is enabled, but otherwise the check should simply return -ENOTSUPP. Loongarch tripped over the same problem and blindly enabled legacy support without implementing the legacy fallbacks. There are weak implementations which return an error, so the problem was papered over. Correct pci_msi_domain_supports() to evaluate the legacy mode and add the missing supported check into the MSI enable path to complete it.

To fix this, the idle task shadow stack initialization was moved to using the CPU hotplug callbacks. But it removed the initialization when the function graph was enabled. The problem here is that the hotplug callbacks are called when the CPUs come online, but the idle shadow stack initialization only happens if function graph is currently active. This caused the online CPUs to not get their shadow stack initialized. The idle shadow stack initialization still needs to be done when the function graph is registered, as they will not be allocated if function graph is not registered.

To fix this, ftrace_get_true_parent_ip() was introduced that returns the "true" parent ip instead of the trampoline. To do this, the ftrace_regs_get_stack_pointer() is used, which uses kernel_stack_pointer(). The problem is that microblaze does not implement kerenl_stack_pointer() so when function graph tracing is enabled, the build fails. But microblaze also does not enabled HAVE_DYNAMIC_FTRACE_WITH_ARGS. That option has to be enabled by the architecture to reliably get the values from the fregs parameter passed in. When that config is not set, the architecture can also pass in NULL, which is not tested for in that function and could cause the kernel to crash.

One place this is regularly seen is with warnings associated with bounds-checking, e.g. -Wstringop-overflow, -Wstringop-overread, -Warray-bounds, etc. In order to keep the signal-to-noise ratio high, warnings aren't emitted when a value range spans the entire value range representable by a given variable. For example: unsigned int len; char dst[8]; ... memcpy(dst, src, len); If len's value is unknown, it has the full "unsigned int" range of [0, UINT_MAX], and GCC's compile-time bounds checks against memcpy() will be ignored. However, when a code path has been able to narrow the range: if (len > 16) return; memcpy(dst, src, len); Then the range will be updated for the execution path. Above, len is now [0, 16] when reading memcpy(), so depending on other optimizations, we might see a -Wstringop-overflow warning like: error: '__builtin_memcpy' writing between 9 and 16 bytes into region of size 8 [-Werror=stringop-overflow] When building with CONFIG_FORTIFY_SOURCE, the fortified run-time bounds checking can appear to narrow value ranges of lengths for memcpy(), depending on how the compiler constructs the execution paths during optimization passes, due to the checks against the field sizes. For example: if (p_size_field != SIZE_MAX && p_size != p_size_field && p_size_field < size) As intentionally designed, these checks only affect the kernel warnings emitted at run-time and do not block the potentially overflowing memcpy(), so GCC thinks it needs to produce a warning about the resulting value range that might be reaching the memcpy(). We have seen this manifest a few times now, with the most recent being with cpumasks: In function ‘bitmap_copy’, inlined from ‘cpumask_copy’ at ./include/linux/cpumask.h:839:2, inlined from ‘__padata_set_cpumasks’ at kernel/padata.c:730:2: ./include/linux/fortify-string.h:114:33: error: ‘__builtin_memcpy’ reading between 257 and 536870904 bytes from a region of size 256 [-Werror=stringop-overread] 114 | #define __underlying_memcpy __builtin_memcpy | ^ ./include/linux/fortify-string.h:633:9: note: in expansion of macro ‘__underlying_memcpy’ 633 | __underlying_##op(p, q, __fortify_size); \ | ^~~~~~~~~~~~~ ./include/linux/fortify-string.h:678:26: note: in expansion of macro ‘__fortify_memcpy_chk’ 678 | #define memcpy(p, q, s) __fortify_memcpy_chk(p, q, s, \ | ^~~~~~~~~~~~~~~~~~~~ ./include/linux/bitmap.h:259:17: note: in expansion of macro ‘memcpy’ 259 | memcpy(dst, src, len); | ^~~~~~ kernel/padata.c: In function ‘__padata_set_cpumasks’: kernel/padata.c:713:48: note: source object ‘pcpumask’ of size [0, 256] 713 | cpumask_var_t pcpumask, | ~~~~~~~~~~~~~~^~~~~~~~ This warning is _not_ emitted when CONFIG_FORTIFY_SOURCE is disabled, and with the recent -fdiagnostics-details we can confirm the origin of the warning is due to FORTIFY's bounds checking: ../include/linux/bitmap.h:259:17: note: in expansion of macro 'memcpy' 259 | memcpy(dst, src, len); | ^~~~~~ '__padata_set_cpumasks': events 1-2 ../include/linux/fortify-string.h:613:36: 612 | if (p_size_field != SIZE_MAX && | ~~~~~~~~~~~~~~~~~~~~~~~~~~~ 613 | p_size != p_size_field && p_size_field < size) | ~~~~~~~~~~~~~~~~~~~~~~~^~~~~~~~~~~~~~~~~~~~~~ | | | (1) when the condition is evaluated to false | (2) when the condition is evaluated to true '__padata_set_cpumasks': event 3 114 | #define __underlying_memcpy __builtin_memcpy | ^ | | | (3) out of array bounds here Note that the cpumask warning started appearing since bitmap functions were recently marked __always_inline in commit ed8cd2b3bd9f ("bitmap: Switch from inline to __always_inline"), which allowed GCC to gain visibility into the variables as they passed through the FORTIFY implementation. In order to silence these false positives but keep otherwise deterministic compile-time warnings intact, hide the length variable from GCC with OPTIMIZE_HIDE_VAR() before calling the builtin memcpy. Additionally add a comment about why all the macro args have copies with const storage.

The intention is that if the device is already open and the queues are already created then we don't create them a second time. However, the bug is that if we have an error in the create_txqs() then the pointer doesn't get set back to NULL. The NULL check at the start of the function will say that it's already open when it's not and the device can't be used. Set ->txqs back to NULL on cleanup on error.

Depending on the guest type and the processor vendor different functions need to be used due to the to be used instruction for entering the hypervisor: - PV guests need to use syscall - HVM/PVH guests on Intel need to use vmcall - HVM/PVH guests on AMD and Hygon need to use vmmcall As PVH guests need to issue hypercalls very early during boot, there is a 4th hypercall function needed for HVM/PVH which can be used on Intel and AMD processors. It will check the vendor type and then set the Intel or AMD specific function to use via static_call(). This is part of XSA-466 / CVE-2024-53241.

This race could result in an active busyness value that is greater than the actual context runtime value by a small amount. This leads to a negative delta and throws off busyness calculations for the user.

SPI thread prepares the tx data chunks from the tx skb pointed by the ongoing_tx_skb pointer. When the tx skb pointed by the ongoing_tx_skb is processed, the tx skb pointed by the waiting_tx_skb is assigned to ongoing_tx_skb and the waiting_tx_skb pointer is assigned with NULL. Whenever there is a new tx skb from n/w stack, it will be assigned to waiting_tx_skb pointer if it is NULL. Enqueuing and processing of a tx skb handled in two different threads. Consider a scenario where the SPI thread processed an ongoing_tx_skb and it moves next tx skb from waiting_tx_skb pointer to ongoing_tx_skb pointer without doing any NULL check. At this time, if the waiting_tx_skb pointer is NULL then ongoing_tx_skb pointer is also assigned with NULL.

We observed the problem while experimenting with a touchscreen driver which used MCP23017 IO expander (I2C). The regmap in the pinctrl-mcp23s08 driver uses a mutex for protection from concurrent accesses, which is the default for regmaps without .fast_io, .disable_locking, etc. mcp23s08_irq_set_type() calls regmap_update_bits_base(), and the latter locks the mutex. However, __setup_irq() locks desc->lock spinlock before calling these functions. As a result, the system tries to lock the mutex whole holding the spinlock. It seems, the internal regmap locks are not needed in this driver at all. mcp->lock seems to protect the regmap from concurrent accesses already, except, probably, in mcp_pinconf_get/set. mcp23s08_irq_set_type() and mcp23s08_irq_mask/unmask() are called under chip_bus_lock(), which calls mcp23s08_irq_bus_lock(). The latter takes mcp->lock and enables regmap caching, so that the potentially slow I2C accesses are deferred until chip_bus_unlock(). The accesses to the regmap from mcp23s08_probe_one() do not need additional locking. In all remaining places where the regmap is accessed, except mcp_pinconf_get/set(), the driver already takes mcp->lock. This patch adds locking in mcp_pinconf_get/set() and disables internal locking in the regmap config. Among other things, it fixes the sleeping in atomic context described above.

The function needs to accurately go from one print format argument to the next. It handles quotes and parenthesis that may be included in an argument. When it finds the start of the next argument, it uses a simple "c = strstr(fmt + i, ',')" to find the end of that argument! In order to include "%s" dereferencing, it needs to process the entire content of the print format argument and not just the content of the first ',' it finds. As there may be content like: ({ const char *saved_ptr = trace_seq_buffer_ptr(p); static const char *access_str[] = { "---", "--x", "w--", "w-x", "-u-", "-ux", "wu-", "wux" }; union kvm_mmu_page_role role; role.word = REC->role; trace_seq_printf(p, "sp gen %u gfn %llx l%u %u-byte q%u%s %s%s" " %snxe %sad root %u %s%c", REC->mmu_valid_gen, REC->gfn, role.level, role.has_4_byte_gpte ? 4 : 8, role.quadrant, role.direct ? " direct" : "", access_str[role.access], role.invalid ? " invalid" : "", role.efer_nx ? "" : "!", role.ad_disabled ? "!" : "", REC->root_count, REC->unsync ? "unsync" : "sync", 0); saved_ptr; }) Which is an example of a full argument of an existing event. As the code already handles finding the next print format argument, process the argument at the end of it and not the start of it. This way it has both the start of the argument as well as the end of it. Add a helper function "process_pointer()" that will do the processing during the loop as well as at the end. It also makes the code cleaner and easier to read.

This makes it safe to dereference as the dereference will then point into the event on the ring buffer where the content of the data stays with the event itself. A few helper functions were missing. Those were: __get_rel_dynamic_array() __get_dynamic_array_len() __get_rel_dynamic_array_len() __get_rel_sockaddr() Also add a helper function find_print_string() to not need to use a middle man variable to test if the string exists.

But currently it does not handle "%s", as there's cases where the string pointer saved in the ring buffer points to a static string in the kernel that will never be freed. As that is a valid case, the pointer needs to be checked at runtime. Currently the runtime check is done via trace_check_vprintf(), but to not have to replicate everything in vsnprintf() it does some logic with the va_list that may not be reliable across architectures. In order to get rid of that logic, more work in the test_event_printk() needs to be done. Some of the strings can be validated at this time when it is obvious the string is valid because the string will be saved in the ring buffer content. Do all the validation of strings in the ring buffer at boot in test_event_printk(), and make sure that the field of the strings that point into the kernel are accessible. This will allow adding checks at runtime that will validate the fields themselves and not rely on paring the TP_printk() format at runtime.

This can happen seconds, minutes, hours, days, months, years possibly later since the event was recorded. If the print format contains a dereference to a string via "%s", and that string was allocated, there's a chance that string could be freed before it is read by the trace file. To protect against such bugs, there are two functions that verify the event. The first one is test_event_printk(), which is called when the event is created. It reads the TP_printk() format as well as its arguments to make sure nothing may be dereferencing a pointer that was not copied into the ring buffer along with the event. If it is, it will trigger a WARN_ON(). For strings that use "%s", it is not so easy. The string may not reside in the ring buffer but may still be valid. Strings that are static and part of the kernel proper which will not be freed for the life of the running system, are safe to dereference. But to know if it is a pointer to a static string or to something on the heap can not be determined until the event is triggered. This brings us to the second function that tests for the bad dereferencing of strings, trace_check_vprintf(). It would walk through the printf format looking for "%s", and when it finds it, it would validate that the pointer is safe to read. If not, it would produces a WARN_ON() as well and write into the ring buffer "[UNSAFE-MEMORY]". The problem with this is how it used va_list to have vsnprintf() handle all the cases that it didn't need to check. Instead of re-implementing vsnprintf(), it would make a copy of the format up to the %s part, and call vsnprintf() with the current va_list ap variable, where the ap would then be ready to point at the string in question. For architectures that passed va_list by reference this was possible. For architectures that passed it by copy it was not. A test_can_verify() function was used to differentiate between the two, and if it wasn't possible, it would disable it. Even for architectures where this was feasible, it was a stretch to rely on such a method that is undocumented, and could cause issues later on with new optimizations of the compiler. Instead, the first function test_event_printk() was updated to look at "%s" as well. If the "%s" argument is a pointer outside the event in the ring buffer, it would find the field type of the event that is the problem and mark the structure with a new flag called "needs_test". The event itself will be marked by TRACE_EVENT_FL_TEST_STR to let it be known that this event has a field that needs to be verified before the event can be printed using the printf format. When the event fields are created from the field type structure, the fields would copy the field type's "needs_test" value. Finally, before being printed, a new function ignore_event() is called which will check if the event has the TEST_STR flag set (if not, it returns false). If the flag is set, it then iterates through the events fields looking for the ones that have the "needs_test" flag set. Then it uses the offset field from the field structure to find the pointer in the ring buffer event. It runs the tests to make sure that pointer is safe to print and if not, it triggers the WARN_ON() and also adds to the trace output that the event in question has an unsafe memory access. The ignore_event() makes the trace_check_vprintf() obsolete so it is removed.

It looks like I missed a few spots where we drop the wait_lock and potentially call into schedule without waking up the tasks on the wake_q structure. Since the tasks being woken are ww_mutex tasks they need to be able to run to release the mutex and unblock the task that currently is planning to wake them. Thus we can deadlock.

This is because for normal subvolumes this is set to 0, and for snapshots it's set to the creation generation. The idea being that if the generation of the node is less than or equal to our creation generation then we don't need to visit that node, because it doesn't belong to us, we can simply drop our reference and move on. However reloc roots don't have their generation stored in root->root_key.offset, instead that is the objectid of their corresponding fs root. This means we can incorrectly not walk into nodes that need to be dropped when deleting a reloc root. There are a variety of consequences to making the wrong choice in two distinct areas. visit_node_for_delete() 1. False positive. We think we are newer than the block when we really aren't. We don't visit the node and drop our reference to the node and carry on. This would result in leaked space. 2. False negative. We do decide to walk down into a block that we should have just dropped our reference to. However this means that the child node will have refs > 1, so we will switch to UPDATE_BACKREF, and then the subsequent walk_down_proc() will notice that btrfs_header_owner(node) != root->root_key.objectid and it'll break out of the loop, and then walk_up_proc() will drop our reference, so this appears to be ok. do_walk_down() 1. False positive. We are in UPDATE_BACKREF and incorrectly decide that we are done and don't need to update the backref for our lower nodes. This is another case that simply won't happen with relocation, as we only have to do UPDATE_BACKREF if the node below us was shared and didn't have FULL_BACKREF set, and since we don't own that node because we're a reloc root we actually won't end up in this case. 2. False negative. Again this is tricky because as described above, we simply wouldn't be here from relocation, because we don't own any of the nodes because we never set btrfs_header_owner() to the reloc root objectid, and we always use FULL_BACKREF, we never actually need to set FULL_BACKREF on any children. Having spent a lot of time stressing relocation/snapshot delete recently I've not seen this pop in practice. But this is objectively incorrect, so fix this to get the correct starting generation based on the root we're dropping to keep me from thinking there's a problem here.

This causes NFSD to avoid the use of background copy even though the actual background copy workload might no longer be running.

For example, we are in wb_on_itr mode and a Tx completion is generated by HW, ready to be written back, as we are re-enabling interrupts: HW SW | | | | idpf_tx_splitq_clean_all | | napi_complete_done | | | tx_completion_wb | idpf_vport_intr_update_itr_ena_irq That tx_completion_wb happens before the vector is fully re-enabled. Continuing with this example, it is a UDP stream and the tx_completion_wb is the last one in the flow (there are no rx packets). Because the HW generated the completion before the interrupt is fully enabled, the HW will not fire the interrupt once the timer expires and the write back will not happen. NAPI poll won't be called. We have indicated we're back in interrupt mode but nothing else will trigger the interrupt. Therefore, the completion goes unprocessed, triggering a Tx timeout. To mitigate this, fire a SW triggered interrupt upon exiting wb_on_itr. This interrupt will catch the rogue completion and avoid the timeout. Add logic to set the appropriate bits in the vector's dyn_ctl register.

Consider the following sequence of events: - IR register is read, interrupt X is set - A new interrupt Y is triggered in the m_can controller - IR register is written to acknowledge interrupt X. Y remains set in IR As at no point in this sequence no interrupt flag is set in IR, the m_can interrupt line will never become deasserted, and no edge will ever be observed to trigger another run of the ISR. This was observed to result in the TX queue of the EHL m_can to get stuck under high load, because frames were queued to the hardware in m_can_start_xmit(), but m_can_finish_tx() was never run to account for their successful transmission. On an Elkhart Lake based board with the two CAN interfaces connected to each other, the following script can reproduce the issue: ip link set can0 up type can bitrate 1000000 ip link set can1 up type can bitrate 1000000 cangen can0 -g 2 -I 000 -L 8 & cangen can0 -g 2 -I 001 -L 8 & cangen can0 -g 2 -I 002 -L 8 & cangen can0 -g 2 -I 003 -L 8 & cangen can0 -g 2 -I 004 -L 8 & cangen can0 -g 2 -I 005 -L 8 & cangen can0 -g 2 -I 006 -L 8 & cangen can0 -g 2 -I 007 -L 8 & cangen can1 -g 2 -I 100 -L 8 & cangen can1 -g 2 -I 101 -L 8 & cangen can1 -g 2 -I 102 -L 8 & cangen can1 -g 2 -I 103 -L 8 & cangen can1 -g 2 -I 104 -L 8 & cangen can1 -g 2 -I 105 -L 8 & cangen can1 -g 2 -I 106 -L 8 & cangen can1 -g 2 -I 107 -L 8 & stress-ng --matrix 0 & To fix the issue, repeatedly read and acknowledge interrupts at the start of the ISR until no interrupt flags are set, so the next incoming interrupt will also result in an edge on the interrupt line. While we have received a report that even with this patch, the TX queue can become stuck under certain (currently unknown) circumstances on the Elkhart Lake, this patch completely fixes the issue with the above reproducer, and it is unclear whether the remaining issue has a similar cause at all.

The boundaries are not correctly checked and computed as it happens only when the temperature is increasing or decreasing. The problem arises because the routine to detect when we cross a threshold is correlated with the computation of the boundaries. We assume we have to recompute the boundaries when a threshold is crossed but actually we should do that even if the it is not the case. Mixing the boundaries computation and the threshold detection for the sake of optimizing the routine is much more complex as it appears intuitively and prone to errors. This fix separates the boundaries computation and the threshold crossing detection into different routines. The result is a code much more simple to understand, thus easier to maintain. The drawback is we browse the thresholds list several time but we can consider that as neglictible because that happens when the temperature is updated. There are certainly some aeras to improve in the temperature update routine but it would be not adequate as this change aims to fix the thresholds for v6.13.

This commit fixes an issue when a CS would fail validation and would be rejected after job->num_ibs is incremented. In this case, amdgpu_ib_free(ring->adev, ...) will be called, which would crash the machine because the ring value is bogus. To fix this, pass a NULL pointer to amdgpu_ib_free(): we can do this because the device is actually not used in this function. The next commit will remove the ring argument completely.

It may include pointers to strings and such. A boot mapped buffer may contain data from a previous kernel where the strings addresses are different. One solution is to copy the event content and update the pointers by the recorded delta, but a simpler solution (for now) is to just use the print_fields() function to print these events. The print_fields() function just iterates the fields and prints them according to what type they are, and ignores the TP_printk() format from the event itself. To understand the difference, when printing via TP_printk() the output looks like this: 4582.696626: kmem_cache_alloc: call_site=getname_flags+0x47/0x1f0 ptr=00000000e70e10e0 bytes_req=4096 bytes_alloc=4096 gfp_flags=GFP_KERNEL node=-1 accounted=false 4582.696629: kmem_cache_alloc: call_site=alloc_empty_file+0x6b/0x110 ptr=0000000095808002 bytes_req=360 bytes_alloc=384 gfp_flags=GFP_KERNEL node=-1 accounted=false 4582.696630: kmem_cache_alloc: call_site=security_file_alloc+0x24/0x100 ptr=00000000576339c3 bytes_req=16 bytes_alloc=16 gfp_flags=GFP_KERNEL|__GFP_ZERO node=-1 accounted=false 4582.696653: kmem_cache_free: call_site=do_sys_openat2+0xa7/0xd0 ptr=00000000e70e10e0 name=names_cache But when printing via print_fields() (echo 1 > /sys/kernel/tracing/options/fields) the same event output looks like this: 4582.696626: kmem_cache_alloc: call_site=0xffffffff92d10d97 (-1831793257) ptr=0xffff9e0e8571e000 (-107689771147264) bytes_req=0x1000 (4096) bytes_alloc=0x1000 (4096) gfp_flags=0xcc0 (3264) node=0xffffffff (-1) accounted=(0) 4582.696629: kmem_cache_alloc: call_site=0xffffffff92d0250b (-1831852789) ptr=0xffff9e0e8577f800 (-107689770747904) bytes_req=0x168 (360) bytes_alloc=0x180 (384) gfp_flags=0xcc0 (3264) node=0xffffffff (-1) accounted=(0) 4582.696630: kmem_cache_alloc: call_site=0xffffffff92efca74 (-1829778828) ptr=0xffff9e0e8d35d3b0 (-107689640864848) bytes_req=0x10 (16) bytes_alloc=0x10 (16) gfp_flags=0xdc0 (3520) node=0xffffffff (-1) accounted=(0) 4582.696653: kmem_cache_free: call_site=0xffffffff92cfbea7 (-1831879001) ptr=0xffff9e0e8571e000 (-107689771147264) name=names_cache Cc: stable@vger.kernel.org Cc: Masami Hiramatsu Cc: Mathieu Desnoyers Cc: Linus Torvalds Link: https://lore.kernel.org/20241218141507.28389a1d@gandalf.local.home Fixes: 07714b4bb3f98 ("tracing: Handle old buffer mappings for event strings and functions") Signed-off-by: Steven Rostedt (Google) --- kernel/trace/trace.c | 9 +++++++++ 1 file changed, 9 insertions(+) diff --git a/kernel/trace/trace.c b/kernel/trace/trace.c index be62f0ea1814d..6581cb2bc67f9 100644 --- a/kernel/trace/trace.c +++ b/kernel/trace/trace.c @@ -4353,6 +4353,15 @@ static enum print_line_t print_trace_fmt(struct trace_iterator *iter) if (event) { if (tr->trace_flags & TRACE_ITER_FIELDS) return print_event_fields(iter, event); + /* + * For TRACE_EVENT() events, the print_fmt is not + * safe to use if the array has delta offsets + * Force printing via the fields. + */ + if ((tr->text_delta || tr->data_delta) && + event->type > __TRACE_LAST_TYPE) + return print_event_fields(iter, event); + return event->funcs->trace(iter, sym_flags, event); } From 0674188f2f4d38d74aa863f17373d76256f2ed09 Mon Sep 17 00:00:00 2001 From: Huacai Chen Date: Tue, 17 Dec 2024 15:37:04 +0800 Subject: [PATCH 0949/1256] ACPI: EC: Enable EC support on LoongArch by default Commit a6021aa24f6417416d933 ("ACPI: EC: make EC support compile-time conditional") only enable ACPI_EC on X86 by default, but the embedded controller is also widely used on LoongArch laptops so we also enable ACPI_EC for LoongArch.

This means: A process going through execve while having registered rings will leak references to the rings' `struct file`. Fix it by zapping registered rings on execve(). This is implemented by moving the io_uring_unreg_ringfd() from io_uring_files_cancel() into its callee __io_uring_cancel(), which is called from io_uring_task_cancel() on execve. This could probably be exploited *on 32-bit kernels* by leaking 2^32 references to the same ring, because the file refcount is stored in a pointer-sized field and get_file() doesn't have protection against refcount overflow, just a WARN_ONCE(); but on 64-bit it should have no impact beyond a memory leak.

While we have a number of disparate comments scattered around the place, we seem to be reaching a level of complexity that justifies a serious effort at clearly documenting how locks are expected to be used when it comes to interacting with mm_struct and vm_area_struct objects. This is especially pertinent as regards the efforts to find sensible abstractions for these fundamental objects in kernel rust code whose compiler strictly requires some means of expressing these rules (and through this expression, self-document these requirements as well as enforce them). The document limits scope to mmap and VMA locks and those that are immediately adjacent and relevant to them - so additionally covers page table locking as this is so very closely tied to VMA operations (and relies upon us handling these correctly). The document tries to cover some of the nastier and more confusing edge cases and concerns especially around lock ordering and page table teardown. The document is split between generally useful information for users of mm interfaces, and separately a section intended for mm kernel developers providing a discussion around internal implementation details.

Offsets into these pages are provided +by the virtual address itself. + +In Linux these are divided into five levels - PGD, P4D, PUD, PMD and PTE. Huge +pages might eliminate one or two of these levels, but when this is the case we +typically refer to the leaf level as the PTE level regardless. + +.. note:: In instances where the architecture supports fewer page tables than + five the kernel cleverly 'folds' page table levels, that is stubbing + out functions related to the skipped levels. This allows us to + conceptually act as if there were always five levels, even if the + compiler might, in practice, eliminate any code relating to missing + ones. + +There are four key operations typically performed on page tables: + +1. **Traversing** page tables - Simply reading page tables in order to traverse + them. This only requires that the VMA is kept stable, so a lock which + establishes this suffices for traversal (there are also lockless variants + which eliminate even this requirement, such as :c:func:`!gup_fast`). +2. **Installing** page table mappings - Whether creating a new mapping or + modifying an existing one in such a way as to change its identity. This + requires that the VMA is kept stable via an mmap or VMA lock (explicitly not + rmap locks). +3. **Zapping/unmapping** page table entries - This is what the kernel calls + clearing page table mappings at the leaf level only, whilst leaving all page + tables in place. This is a very common operation in the kernel performed on + file truncation, the :c:macro:`!MADV_DONTNEED` operation via + :c:func:`!madvise`, and others. This is performed by a number of functions + including :c:func:`!unmap_mapping_range` and :c:func:`!unmap_mapping_pages`. + The VMA need only be kept stable for this operation. +4. **Freeing** page tables - When finally the kernel removes page tables from a + userland process (typically via :c:func:`!free_pgtables`) extreme care must + be taken to ensure this is done safely, as this logic finally frees all page + tables in the specified range, ignoring existing leaf entries (it assumes the + caller has both zapped the range and prevented any further faults or + modifications within it). + +.. note:: Modifying mappings for reclaim or migration is performed under rmap + lock as it, like zapping, does not fundamentally modify the identity + of what is being mapped. + +**Traversing** and **zapping** ranges can be performed holding any one of the +locks described in the terminology section above - that is the mmap lock, the +VMA lock or either of the reverse mapping locks. + +That is - as long as you keep the relevant VMA **stable** - you are good to go +ahead and perform these operations on page tables (though internally, kernel +operations that perform writes also acquire internal page table locks to +serialise - see the page table implementation detail section for more details). + +When **installing** page table entries, the mmap or VMA lock must be held to +keep the VMA stable. We explore why this is in the page table locking details +section below. + +.. warning:: Page tables are normally only traversed in regions covered by VMAs. + If you want to traverse page tables in areas that might not be + covered by VMAs, heavier locking is required. + See :c:func:`!walk_page_range_novma` for details. + +**Freeing** page tables is an entirely internal memory management operation and +has special requirements (see the page freeing section below for more details). + +.. warning:: When **freeing** page tables, it must not be possible for VMAs + containing the ranges those page tables map to be accessible via + the reverse mapping. + + The :c:func:`!free_pgtables` function removes the relevant VMAs + from the reverse mappings, but no other VMAs can be permitted to be + accessible and span the specified range. + +Lock ordering +------------- + +As we have multiple locks across the kernel which may or may not be taken at the +same time as explicit mm or VMA locks, we have to be wary of lock inversion, and +the **order** in which locks are acquired and released becomes very important. + +.. note:: Lock inversion occurs when two threads need to acquire multiple locks, + but in doing so inadvertently cause a mutual deadlock. + + For example, consider thread 1 which holds lock A and tries to acquire lock B, + while thread 2 holds lock B and tries to acquire lock A. + + Both threads are now deadlocked on each other. However, had they attempted to + acquire locks in the same order, one would have waited for the other to + complete its work and no deadlock would have occurred. + +The opening comment in :c:macro:`!mm/rmap.c` describes in detail the required +ordering of locks within memory management code: + +.. code-block:: + + inode->i_rwsem (while writing or truncating, not reading or faulting) + mm->mmap_lock + mapping->invalidate_lock (in filemap_fault) + folio_lock + hugetlbfs_i_mmap_rwsem_key (in huge_pmd_share, see hugetlbfs below) + vma_start_write + mapping->i_mmap_rwsem + anon_vma->rwsem + mm->page_table_lock or pte_lock + swap_lock (in swap_duplicate, swap_info_get) + mmlist_lock (in mmput, drain_mmlist and others) + mapping->private_lock (in block_dirty_folio) + i_pages lock (widely used) + lruvec->lru_lock (in folio_lruvec_lock_irq) + inode->i_lock (in set_page_dirty's __mark_inode_dirty) + bdi.wb->list_lock (in set_page_dirty's __mark_inode_dirty) + sb_lock (within inode_lock in fs/fs-writeback.c) + i_pages lock (widely used, in set_page_dirty, + in arch-dependent flush_dcache_mmap_lock, + within bdi.wb->list_lock in __sync_single_inode) + +There is also a file-system specific lock ordering comment located at the top of +:c:macro:`!mm/filemap.c`: + +.. code-block:: + + ->i_mmap_rwsem (truncate_pagecache) + ->private_lock (__free_pte->block_dirty_folio) + ->swap_lock (exclusive_swap_page, others) + ->i_pages lock + + ->i_rwsem + ->invalidate_lock (acquired by fs in truncate path) + ->i_mmap_rwsem (truncate->unmap_mapping_range) + + ->mmap_lock + ->i_mmap_rwsem + ->page_table_lock or pte_lock (various, mainly in memory.c) + ->i_pages lock (arch-dependent flush_dcache_mmap_lock) + + ->mmap_lock + ->invalidate_lock (filemap_fault) + ->lock_page (filemap_fault, access_process_vm) + + ->i_rwsem (generic_perform_write) + ->mmap_lock (fault_in_readable->do_page_fault) + + bdi->wb.list_lock + sb_lock (fs/fs-writeback.c) + ->i_pages lock (__sync_single_inode) + + ->i_mmap_rwsem + ->anon_vma.lock (vma_merge) + + ->anon_vma.lock + ->page_table_lock or pte_lock (anon_vma_prepare and various) + + ->page_table_lock or pte_lock + ->swap_lock (try_to_unmap_one) + ->private_lock (try_to_unmap_one) + ->i_pages lock (try_to_unmap_one) + ->lruvec->lru_lock (follow_page_mask->mark_page_accessed) + ->lruvec->lru_lock (check_pte_range->folio_isolate_lru) + ->private_lock (folio_remove_rmap_pte->set_page_dirty) + ->i_pages lock (folio_remove_rmap_pte->set_page_dirty) + bdi.wb->list_lock (folio_remove_rmap_pte->set_page_dirty) + ->inode->i_lock (folio_remove_rmap_pte->set_page_dirty) + bdi.wb->list_lock (zap_pte_range->set_page_dirty) + ->inode->i_lock (zap_pte_range->set_page_dirty) + ->private_lock (zap_pte_range->block_dirty_folio) + +Please check the current state of these comments which may have changed since +the time of writing of this document. + +------------------------------ +Locking Implementation Details +------------------------------ + +.. warning:: Locking rules for PTE-level page tables are very different from + locking rules for page tables at other levels. + +Page table locking details +-------------------------- + +In addition to the locks described in the terminology section above, we have +additional locks dedicated to page tables: + +* **Higher level page table locks** - Higher level page tables, that is PGD, P4D + and PUD each make use of the process address space granularity + :c:member:`!mm->page_table_lock` lock when modified. + +* **Fine-grained page table locks** - PMDs and PTEs each have fine-grained locks + either kept within the folios describing the page tables or allocated + separated and pointed at by the folios if :c:macro:`!ALLOC_SPLIT_PTLOCKS` is + set. The PMD spin lock is obtained via :c:func:`!pmd_lock`, however PTEs are + mapped into higher memory (if a 32-bit system) and carefully locked via + :c:func:`!pte_offset_map_lock`. + +These locks represent the minimum required to interact with each page table +level, but there are further requirements. + +Importantly, note that on a **traversal** of page tables, sometimes no such +locks are taken. However, at the PTE level, at least concurrent page table +deletion must be prevented (using RCU) and the page table must be mapped into +high memory, see below. + +Whether care is taken on reading the page table entries depends on the +architecture, see the section on atomicity below. + +Locking rules +^^^^^^^^^^^^^ + +We establish basic locking rules when interacting with page tables: + +* When changing a page table entry the page table lock for that page table + **must** be held, except if you can safely assume nobody can access the page + tables concurrently (such as on invocation of :c:func:`!free_pgtables`). +* Reads from and writes to page table entries must be *appropriately* + atomic. See the section on atomicity below for details. +* Populating previously empty entries requires that the mmap or VMA locks are + held (read or write), doing so with only rmap locks would be dangerous (see + the warning below). +* As mentioned previously, zapping can be performed while simply keeping the VMA + stable, that is holding any one of the mmap, VMA or rmap locks. + +.. warning:: Populating previously empty entries is dangerous as, when unmapping + VMAs, :c:func:`!vms_clear_ptes` has a window of time between + zapping (via :c:func:`!unmap_vmas`) and freeing page tables (via + :c:func:`!free_pgtables`), where the VMA is still visible in the + rmap tree. :c:func:`!free_pgtables` assumes that the zap has + already been performed and removes PTEs unconditionally (along with + all other page tables in the freed range), so installing new PTE + entries could leak memory and also cause other unexpected and + dangerous behaviour. + +There are additional rules applicable when moving page tables, which we discuss +in the section on this topic below. + +PTE-level page tables are different from page tables at other levels, and there +are extra requirements for accessing them: + +* On 32-bit architectures, they may be in high memory (meaning they need to be + mapped into kernel memory to be accessible). +* When empty, they can be unlinked and RCU-freed while holding an mmap lock or + rmap lock for reading in combination with the PTE and PMD page table locks. + In particular, this happens in :c:func:`!retract_page_tables` when handling + :c:macro:`!MADV_COLLAPSE`. + So accessing PTE-level page tables requires at least holding an RCU read lock; + but that only suffices for readers that can tolerate racing with concurrent + page table updates such that an empty PTE is observed (in a page table that + has actually already been detached and marked for RCU freeing) while another + new page table has been installed in the same location and filled with + entries. Writers normally need to take the PTE lock and revalidate that the + PMD entry still refers to the same PTE-level page table. + +To access PTE-level page tables, a helper like :c:func:`!pte_offset_map_lock` or +:c:func:`!pte_offset_map` can be used depending on stability requirements. +These map the page table into kernel memory if required, take the RCU lock, and +depending on variant, may also look up or acquire the PTE lock. +See the comment on :c:func:`!__pte_offset_map_lock`. + +Atomicity +^^^^^^^^^ + +Regardless of page table locks, the MMU hardware concurrently updates accessed +and dirty bits (perhaps more, depending on architecture). Additionally, page +table traversal operations in parallel (though holding the VMA stable) and +functionality like GUP-fast locklessly traverses (that is reads) page tables, +without even keeping the VMA stable at all. + +When performing a page table traversal and keeping the VMA stable, whether a +read must be performed once and only once or not depends on the architecture +(for instance x86-64 does not require any special precautions). + +If a write is being performed, or if a read informs whether a write takes place +(on an installation of a page table entry say, for instance in +:c:func:`!__pud_install`), special care must always be taken. In these cases we +can never assume that page table locks give us entirely exclusive access, and +must retrieve page table entries once and only once. + +If we are reading page table entries, then we need only ensure that the compiler +does not rearrange our loads. This is achieved via :c:func:`!pXXp_get` +functions - :c:func:`!pgdp_get`, :c:func:`!p4dp_get`, :c:func:`!pudp_get`, +:c:func:`!pmdp_get`, and :c:func:`!ptep_get`. + +Each of these uses :c:func:`!READ_ONCE` to guarantee that the compiler reads +the page table entry only once. + +However, if we wish to manipulate an existing page table entry and care about +the previously stored data, we must go further and use an hardware atomic +operation as, for example, in :c:func:`!ptep_get_and_clear`. + +Equally, operations that do not rely on the VMA being held stable, such as +GUP-fast (see :c:func:`!gup_fast` and its various page table level handlers like +:c:func:`!gup_fast_pte_range`), must very carefully interact with page table +entries, using functions such as :c:func:`!ptep_get_lockless` and equivalent for +higher level page table levels. + +Writes to page table entries must also be appropriately atomic, as established +by :c:func:`!set_pXX` functions - :c:func:`!set_pgd`, :c:func:`!set_p4d`, +:c:func:`!set_pud`, :c:func:`!set_pmd`, and :c:func:`!set_pte`. + +Equally functions which clear page table entries must be appropriately atomic, +as in :c:func:`!pXX_clear` functions - :c:func:`!pgd_clear`, +:c:func:`!p4d_clear`, :c:func:`!pud_clear`, :c:func:`!pmd_clear`, and +:c:func:`!pte_clear`. + +Page table installation +^^^^^^^^^^^^^^^^^^^^^^^ + +Page table installation is performed with the VMA held stable explicitly by an +mmap or VMA lock in read or write mode (see the warning in the locking rules +section for details as to why). + +When allocating a P4D, PUD or PMD and setting the relevant entry in the above +PGD, P4D or PUD, the :c:member:`!mm->page_table_lock` must be held. This is +acquired in :c:func:`!__p4d_alloc`, :c:func:`!__pud_alloc` and +:c:func:`!__pmd_alloc` respectively. + +.. note:: :c:func:`!__pmd_alloc` actually invokes :c:func:`!pud_lock` and + :c:func:`!pud_lockptr` in turn, however at the time of writing it ultimately + references the :c:member:`!mm->page_table_lock`. + +Allocating a PTE will either use the :c:member:`!mm->page_table_lock` or, if +:c:macro:`!USE_SPLIT_PMD_PTLOCKS` is defined, a lock embedded in the PMD +physical page metadata in the form of a :c:struct:`!struct ptdesc`, acquired by +:c:func:`!pmd_ptdesc` called from :c:func:`!pmd_lock` and ultimately +:c:func:`!__pte_alloc`. + +Finally, modifying the contents of the PTE requires special treatment, as the +PTE page table lock must be acquired whenever we want stable and exclusive +access to entries contained within a PTE, especially when we wish to modify +them. + +This is performed via :c:func:`!pte_offset_map_lock` which carefully checks to +ensure that the PTE hasn't changed from under us, ultimately invoking +:c:func:`!pte_lockptr` to obtain a spin lock at PTE granularity contained within +the :c:struct:`!struct ptdesc` associated with the physical PTE page. The lock +must be released via :c:func:`!pte_unmap_unlock`. + +.. note:: There are some variants on this, such as + :c:func:`!pte_offset_map_rw_nolock` when we know we hold the PTE stable but + for brevity we do not explore this. See the comment for + :c:func:`!__pte_offset_map_lock` for more details. + +When modifying data in ranges we typically only wish to allocate higher page +tables as necessary, using these locks to avoid races or overwriting anything, +and set/clear data at the PTE level as required (for instance when page faulting +or zapping). + +A typical pattern taken when traversing page table entries to install a new +mapping is to optimistically determine whether the page table entry in the table +above is empty, if so, only then acquiring the page table lock and checking +again to see if it was allocated underneath us. + +This allows for a traversal with page table locks only being taken when +required. An example of this is :c:func:`!__pud_alloc`. + +At the leaf page table, that is the PTE, we can't entirely rely on this pattern +as we have separate PMD and PTE locks and a THP collapse for instance might have +eliminated the PMD entry as well as the PTE from under us. + +This is why :c:func:`!__pte_offset_map_lock` locklessly retrieves the PMD entry +for the PTE, carefully checking it is as expected, before acquiring the +PTE-specific lock, and then *again* checking that the PMD entry is as expected. + +If a THP collapse (or similar) were to occur then the lock on both pages would +be acquired, so we can ensure this is prevented while the PTE lock is held. + +Installing entries this way ensures mutual exclusion on write. + +Page table freeing +^^^^^^^^^^^^^^^^^^ + +Tearing down page tables themselves is something that requires significant +care. There must be no way that page tables designated for removal can be +traversed or referenced by concurrent tasks. + +It is insufficient to simply hold an mmap write lock and VMA lock (which will +prevent racing faults, and rmap operations), as a file-backed mapping can be +truncated under the :c:struct:`!struct address_space->i_mmap_rwsem` alone. + +As a result, no VMA which can be accessed via the reverse mapping (either +through the :c:struct:`!struct anon_vma->rb_root` or the :c:member:`!struct +address_space->i_mmap` interval trees) can have its page tables torn down. + +The operation is typically performed via :c:func:`!free_pgtables`, which assumes +either the mmap write lock has been taken (as specified by its +:c:member:`!mm_wr_locked` parameter), or that the VMA is already unreachable. + +It carefully removes the VMA from all reverse mappings, however it's important +that no new ones overlap these or any route remain to permit access to addresses +within the range whose page tables are being torn down. + +Additionally, it assumes that a zap has already been performed and steps have +been taken to ensure that no further page table entries can be installed between +the zap and the invocation of :c:func:`!free_pgtables`. + +Since it is assumed that all such steps have been taken, page table entries are +cleared without page table locks (in the :c:func:`!pgd_clear`, :c:func:`!p4d_clear`, +:c:func:`!pud_clear`, and :c:func:`!pmd_clear` functions. + +.. note:: It is possible for leaf page tables to be torn down independent of + the page tables above it as is done by + :c:func:`!retract_page_tables`, which is performed under the i_mmap + read lock, PMD, and PTE page table locks, without this level of care. + +Page table moving +^^^^^^^^^^^^^^^^^ + +Some functions manipulate page table levels above PMD (that is PUD, P4D and PGD +page tables). Most notable of these is :c:func:`!mremap`, which is capable of +moving higher level page tables. + +In these instances, it is required that **all** locks are taken, that is +the mmap lock, the VMA lock and the relevant rmap locks. + +You can observe this in the :c:func:`!mremap` implementation in the functions +:c:func:`!take_rmap_locks` and :c:func:`!drop_rmap_locks` which perform the rmap +side of lock acquisition, invoked ultimately by :c:func:`!move_page_tables`. + +VMA lock internals +------------------ + +Overview +^^^^^^^^ + +VMA read locking is entirely optimistic - if the lock is contended or a competing +write has started, then we do not obtain a read lock. + +A VMA **read** lock is obtained by :c:func:`!lock_vma_under_rcu`, which first +calls :c:func:`!rcu_read_lock` to ensure that the VMA is looked up in an RCU +critical section, then attempts to VMA lock it via :c:func:`!vma_start_read`, +before releasing the RCU lock via :c:func:`!rcu_read_unlock`. + +VMA read locks hold the read lock on the :c:member:`!vma->vm_lock` semaphore for +their duration and the caller of :c:func:`!lock_vma_under_rcu` must release it +via :c:func:`!vma_end_read`. + +VMA **write** locks are acquired via :c:func:`!vma_start_write` in instances where a +VMA is about to be modified, unlike :c:func:`!vma_start_read` the lock is always +acquired. An mmap write lock **must** be held for the duration of the VMA write +lock, releasing or downgrading the mmap write lock also releases the VMA write +lock so there is no :c:func:`!vma_end_write` function. + +Note that a semaphore write lock is not held across a VMA lock. Rather, a +sequence number is used for serialisation, and the write semaphore is only +acquired at the point of write lock to update this. + +This ensures the semantics we require - VMA write locks provide exclusive write +access to the VMA. + +Implementation details +^^^^^^^^^^^^^^^^^^^^^^ + +The VMA lock mechanism is designed to be a lightweight means of avoiding the use +of the heavily contended mmap lock. It is implemented using a combination of a +read/write semaphore and sequence numbers belonging to the containing +:c:struct:`!struct mm_struct` and the VMA. + +Read locks are acquired via :c:func:`!vma_start_read`, which is an optimistic +operation, i.e. it tries to acquire a read lock but returns false if it is +unable to do so. At the end of the read operation, :c:func:`!vma_end_read` is +called to release the VMA read lock. + +Invoking :c:func:`!vma_start_read` requires that :c:func:`!rcu_read_lock` has +been called first, establishing that we are in an RCU critical section upon VMA +read lock acquisition. Once acquired, the RCU lock can be released as it is only +required for lookup. This is abstracted by :c:func:`!lock_vma_under_rcu` which +is the interface a user should use. + +Writing requires the mmap to be write-locked and the VMA lock to be acquired via +:c:func:`!vma_start_write`, however the write lock is released by the termination or +downgrade of the mmap write lock so no :c:func:`!vma_end_write` is required. + +All this is achieved by the use of per-mm and per-VMA sequence counts, which are +used in order to reduce complexity, especially for operations which write-lock +multiple VMAs at once. + +If the mm sequence count, :c:member:`!mm->mm_lock_seq` is equal to the VMA +sequence count :c:member:`!vma->vm_lock_seq` then the VMA is write-locked. If +they differ, then it is not. + +Each time the mmap write lock is released in :c:func:`!mmap_write_unlock` or +:c:func:`!mmap_write_downgrade`, :c:func:`!vma_end_write_all` is invoked which +also increments :c:member:`!mm->mm_lock_seq` via +:c:func:`!mm_lock_seqcount_end`. + +This way, we ensure that, regardless of the VMA's sequence number, a write lock +is never incorrectly indicated and that when we release an mmap write lock we +efficiently release **all** VMA write locks contained within the mmap at the +same time. + +Since the mmap write lock is exclusive against others who hold it, the automatic +release of any VMA locks on its release makes sense, as you would never want to +keep VMAs locked across entirely separate write operations. It also maintains +correct lock ordering. + +Each time a VMA read lock is acquired, we acquire a read lock on the +:c:member:`!vma->vm_lock` read/write semaphore and hold it, while checking that +the sequence count of the VMA does not match that of the mm. + +If it does, the read lock fails. If it does not, we hold the lock, excluding +writers, but permitting other readers, who will also obtain this lock under RCU. + +Importantly, maple tree operations performed in :c:func:`!lock_vma_under_rcu` +are also RCU safe, so the whole read lock operation is guaranteed to function +correctly. + +On the write side, we acquire a write lock on the :c:member:`!vma->vm_lock` +read/write semaphore, before setting the VMA's sequence number under this lock, +also simultaneously holding the mmap write lock. + +This way, if any read locks are in effect, :c:func:`!vma_start_write` will sleep +until these are finished and mutual exclusion is achieved. + +After setting the VMA's sequence number, the lock is released, avoiding +complexity with a long-term held write lock. + +This clever combination of a read/write semaphore and sequence count allows for +fast RCU-based per-VMA lock acquisition (especially on page fault, though +utilised elsewhere) with minimal complexity around lock ordering. + +mmap write lock downgrading +--------------------------- + +When an mmap write lock is held one has exclusive access to resources within the +mmap (with the usual caveats about requiring VMA write locks to avoid races with +tasks holding VMA read locks). + +It is then possible to **downgrade** from a write lock to a read lock via +:c:func:`!mmap_write_downgrade` which, similar to :c:func:`!mmap_write_unlock`, +implicitly terminates all VMA write locks via :c:func:`!vma_end_write_all`, but +importantly does not relinquish the mmap lock while downgrading, therefore +keeping the locked virtual address space stable. + +An interesting consequence of this is that downgraded locks are exclusive +against any other task possessing a downgraded lock (since a racing task would +have to acquire a write lock first to downgrade it, and the downgraded lock +prevents a new write lock from being obtained until the original lock is +released). + +For clarity, we map read (R)/downgraded write (D)/write (W) locks against one +another showing which locks exclude the others: + +.. list-table:: Lock exclusivity + :widths: 5 5 5 5 + :header-rows: 1 + :stub-columns: 1 + + * - + - R + - D + - W + * - R + - N + - N + - Y + * - D + - N + - Y + - Y + * - W + - Y + - Y + - Y + +Here a Y indicates the locks in the matching row/column are mutually exclusive, +and N indicates that they are not. + +Stack expansion +--------------- + +Stack expansion throws up additional complexities in that we cannot permit there +to be racing page faults, as a result we invoke :c:func:`!vma_start_write` to +prevent this in :c:func:`!expand_downwards` or :c:func:`!expand_upwards`.

If the kernel the test runs on does not support PID namespaces, the first sysctl test will fail when attempting to spawn a new thread in a new PID namespace, abort the test, preventing the remaining tests from being run. This is not desirable, as not all kernels need PID namespaces, but can still use the other features provided by memfd. Therefore, only run the sysctl tests if the kernel supports PID namespaces. Otherwise, skip those tests and emit an informative message to let the user know why the sysctl tests are not being run.

SUSE QA team detected a mistake in my commit dfe6c5692fb5 ("ocfs2: fix the la space leak when unmounting an ocfs2 volume"). I am very sorry for my error. (If my eyes are correct) From the mailling list mails, this patch shouldn't be applied to 4.19 5.4 5.10 5.15 6.1 6.6, and these branches should perform a revert operation. Reason for revert: In commit dfe6c5692fb5, I mistakenly wrote: "This bug has existed since the initial OCFS2 code.". The statement is wrong. The correct introduction commit is 30dd3478c3cd. IOW, if the branch doesn't include 30dd3478c3cd, dfe6c5692fb5 should also not be included. This reverts commit dfe6c5692fb5 ("ocfs2: fix the la space leak when unmounting an ocfs2 volume"). In commit dfe6c5692fb5, the commit log "This bug has existed since the initial OCFS2 code." is wrong. The correct introduction commit is 30dd3478c3cd ("ocfs2: correctly use ocfs2_find_next_zero_bit()"). The influence of commit dfe6c5692fb5 is that it provides a correct fix for the latest kernel. however, it shouldn't be pushed to stable branches. Let's use this commit to revert all branches that include dfe6c5692fb5 and use a new fix method to fix commit 30dd3478c3cd.

So __GFP_ZERO using only clear_page() is not enough to zero user folios and clear_user_(high)page() must be used. Otherwise, user data will be corrupted. Fix it by always clearing user folios with clear_user_(high)page() when cpu_dcache_is_aliasing() is true or cpu_icache_is_aliasing() is true. Rename alloc_zeroed() to user_alloc_needs_zeroing() and invert the logic to clarify its intend.

This occurs because uprobe_write_opcode() invokes anon_vma_prepare() which in turn invokes find_mergeable_anon_vma() that uses a VMA iterator, invoking vma_iter_load() which uses the advanced maple tree API and thus is able to observe XA_ZERO_ENTRY entries added to dup_mmap() in commit d24062914837 ("fork: use __mt_dup() to duplicate maple tree in dup_mmap()"). This change was made on the assumption that only process tear-down code would actually observe (and make use of) these values. However this very unlikely but still possible edge case with uprobes exists and unfortunately does make these observable. The uprobe operation prevents races against the dup_mmap() operation via the dup_mmap_sem semaphore, which is acquired via uprobe_start_dup_mmap() and dropped via uprobe_end_dup_mmap(), and held across register_for_each_vma() prior to invoking build_map_info() which does the reverse mapping lookup. Currently these are acquired and dropped within dup_mmap(), which exposes the race window prior to error handling in the invoking dup_mm() which tears down the mm. We can avoid all this by just moving the invocation of uprobe_start_dup_mmap() and uprobe_end_dup_mmap() up a level to dup_mm() and only release this lock once the dup_mmap() operation succeeds or clean up is done. This means that the uprobe code can never observe an incompletely constructed mm and resolves the issue in this case.

Unfortunately, some pseudo-inodes in nilfs2 use empty_aops set by inode_init_always_gfp() as is, or explicitly set it to address_space_operations. Therefore, with this change, block_invalidatepage() is no longer called from folio_invalidate(), and as a result, the buffer_head structures attached to these pages/folios are no longer freed via try_to_free_buffers(). Thus, these buffer heads are now leaked by truncate_inode_pages(), which cleans up the page cache from inode evict(), etc. Three types of caches use empty_aops: gc inode caches and the DAT shadow inode used by GC, and b-tree node caches. Of these, b-tree node caches explicitly call invalidate_mapping_pages() during cleanup, which involves calling try_to_free_buffers(), so the leak was not visible during normal operation but worsened when GC was performed. Fix this issue by using address_space_operations with invalidate_folio set to block_invalidate_folio instead of empty_aops, which will ensure the same behavior as before.

He is describing the same symptoms as for commit 1f9fc48fd302 ("net: dsa: sja1105: fix reception from VLAN-unaware bridges"). For context, the set merged as "VLAN fixes for Ocelot driver": https://lore.kernel.org/netdev/20240815000707.2006121-1-vladimir.oltean@nxp.com/ was developed in a slightly different form earlier this year, in January. Initially, the switch was unconditionally configured to set OCELOT_ES0_TAG when using ocelot-8021q, regardless of port operating mode. This led to the situation where VLAN-unaware bridge ports would always push their PVID - see ocelot_vlan_unaware_pvid() - a negligible value anyway - into RX packets. To strip this in software, we would have needed DSA to know what private VID the switch chose for VLAN-unaware bridge ports, and pushed into the packets. This was implemented downstream, and a remnant of it remains in the form of a comment mentioning ds->ops->get_private_vid(), as something which would maybe need to be considered in the future. However, for upstream, it was deemed inappropriate, because it would mean introducing yet another behavior for stripping VLAN tags from VLAN-unaware bridge ports, when one already existed (ds->untag_bridge_pvid). The latter has been marked as obsolete along with an explanation why it is logically broken, but still, it would have been confusing. So, for upstream, felix_update_tag_8021q_rx_rule() was developed, which essentially changed the state of affairs from "Felix with ocelot-8021q delivers all packets as VLAN-tagged towards the CPU" into "Felix with ocelot-8021q delivers all packets from VLAN-aware bridge ports towards the CPU". This was done on the premise that in VLAN-unaware mode, there's nothing useful in the VLAN tags, and we can avoid introducing ds->ops->get_private_vid() in the DSA receive path if we configure the switch to not push those VLAN tags into packets in the first place. Unfortunately, and this is when the trainwreck started, the selftests developed initially and posted with the series were not re-ran. dsa_software_vlan_untag() was initially written given the assumption that users of this feature would send _all_ traffic as VLAN-tagged. It was only partially adapted to the new scheme, by removing ds->ops->get_private_vid(), which also used to be necessary in standalone ports mode. Where the trainwreck became even worse is that I had a second opportunity to think about this, when the dsa_software_vlan_untag() logic change initially broke sja1105, in commit 1f9fc48fd302 ("net: dsa: sja1105: fix reception from VLAN-unaware bridges"). I did not connect the dots that it also breaks ocelot-8021q, for pretty much the same reason that not all received packets will be VLAN-tagged. To be compatible with the optimized Felix control path which runs felix_update_tag_8021q_rx_rule() to only push VLAN tags when useful (in VLAN-aware mode), we need to restore the old dsa_software_vlan_untag() logic. The blamed commit introduced the assumption that dsa_software_vlan_untag() will see only VLAN-tagged packets, assumption which is false. What corrupts RX traffic is the fact that we call skb_vlan_untag() on packets which are not VLAN-tagged in the first place.

Instead, ensure that we're freeing the skb where the sock hasn't otherwise taken ownership of the skb by adding checks on the sock_queue_rcv_skb() to invoke a kfree on failure. In doing so, rather than using the 'rc' value to trigger the kfree_skb(), use the skb pointer itself, which is more explicit. Also, add a kunit test for the sock delivery failure cases.

On these two platforms, the maximum buffer size is given as 512 KiB. The MediaTek common code uses the same value for preallocations. This means that only the first two PCM substreams get preallocations, and then the whole space is exhausted, barring any other substreams from working. Since the substreams used are not always the first two, this means audio won't work correctly. This is observed on the MT8188 Geralt Chromebooks, on which the "mediatek,dai-link" property was dropped when it was upstreamed. That property causes the driver to only register the PCM substreams listed in the property, and in the order given. Instead of trying to compute an optimal value and figuring out which streams are used, simply disable preallocation. The PCM buffers are managed by the core and are allocated and released on the fly. There should be no impact to any of the other MediaTek platforms.

The reason the patch worked for that bug was because we now hold references to the netns (get_net_track() gets a ref internally) and they're properly released (internally, on __sk_destruct()), but only because sk->sk_net_refcnt was set. Problem: (this happens regardless of CONFIG_NET_NS_REFCNT_TRACKER and regardless if init_net or other) Setting sk->sk_net_refcnt=1 *manually* and *after* socket creation is not only out of cifs scope, but also technically wrong -- it's set conditionally based on user (=1) vs kernel (=0) sockets. And net/ implementations seem to base their user vs kernel space operations on it. e.g. upon TCP socket close, the TCP timers are not cleared because sk->sk_net_refcnt=1: (cf. commit 151c9c724d05 ("tcp: properly terminate timers for kernel sockets")) net/ipv4/tcp.c: void tcp_close(struct sock *sk, long timeout) { lock_sock(sk); __tcp_close(sk, timeout); release_sock(sk); if (!sk->sk_net_refcnt) inet_csk_clear_xmit_timers_sync(sk); sock_put(sk); } Which will throw a lockdep warning and then, as expected, deadlock on tcp_write_timer(). A way to reproduce this is by running the reproducer from ef7134c7fc48 and then 'rmmod cifs'. A few seconds later, the deadlock/lockdep warning shows up. Fix: We shouldn't mess with socket internals ourselves, so do not set sk_net_refcnt manually. Also change __sock_create() to sock_create_kern() for explicitness. As for non-init_net network namespaces, we deal with it the best way we can -- hold an extra netns reference for server->ssocket and drop it when it's released. This ensures that the netns still exists whenever we need to create/destroy server->ssocket, but is not directly tied to it.

This is correct when flushing, but when called from the cancel(_delayed)_work_sync() paths it is a false positive because work is either already running, or will not be running at all.

The Max Link Speed field in the Link Capabilities Register indicates the *maximum* of those speeds. pcie_get_supported_speeds() neglects to honor the Max Link Speed field and will thus incorrectly deem higher speeds as supported. Fix it. One user-visible issue addressed here is an incorrect value in the sysfs attribute "max_link_speed". But the main motivation is a boot hang reported by Niklas: Intel JHL7540 "Titan Ridge 2018" Thunderbolt controllers supports 2.5-8 GT/s speeds, but indicate 2.5 GT/s as maximum. Ilpo recalls seeing this on more devices. It can be explained by the controller's Downstream Ports supporting 8 GT/s if an Endpoint is attached, but limiting to 2.5 GT/s if the port interfaces to a PCIe Adapter, in accordance with USB4 v2 sec 11.2.1: "This section defines the functionality of an Internal PCIe Port that interfaces to a PCIe Adapter. [...] The Logical sub-block shall update the PCIe configuration registers with the following characteristics: [...] Max Link Speed field in the Link Capabilities Register set to 0001b (data rate of 2.5 GT/s only). Note: These settings do not represent actual throughput. Throughput is implementation specific and based on the USB4 Fabric performance." The present commit is not sufficient on its own to fix Niklas' boot hang, but it is a prerequisite: A subsequent commit will fix the boot hang by enabling bandwidth control only if more than one speed is supported. The GENMASK() macro used herein specifies 0 as lowest bit, even though the Supported Link Speeds Vector ends at bit 1. This is done on purpose to avoid a GENMASK(0, 1) macro if Max Link Speed is zero. That macro would be invalid as the lowest bit is greater than the highest bit. Ilpo has witnessed a zero Max Link Speed on Root Complex Integrated Endpoints in particular, so it does occur in practice. (The Link Capabilities Register is optional on RCiEPs per PCIe r6.2 sec 7.5.3.)

Not enabling it saves a small amount of memory and compute resources, but also fixes a boot hang reported by Niklas: It occurs when enabling bandwidth control on Downstream Ports of Intel JHL7540 "Titan Ridge 2018" Thunderbolt controllers. The ports only support 2.5 GT/s in accordance with USB4 v2 sec 11.2.1, so the present commit works around the issue. PCIe r6.2 sec 8.2.1 prescribes that: "A device must support 2.5 GT/s and is not permitted to skip support for any data rates between 2.5 GT/s and the highest supported rate." Consequently, bandwidth control is currently only disabled if a port doesn't support higher speeds than 2.5 GT/s. However the Implementation Note in PCIe r6.2 sec 7.5.3.18 cautions: "It is strongly encouraged that software primarily utilize the Supported Link Speeds Vector instead of the Max Link Speed field, so that software can determine the exact set of supported speeds on current and future hardware. This can avoid software being confused if a future specification defines Links that do not require support for all slower speeds." In other words, future revisions of the PCIe Base Spec may allow gaps in the Supported Link Speeds Vector. To be future-proof, don't just check whether speeds above 2.5 GT/s are supported, but rather check whether *more than one* speed is supported.

However, after closing the two FEC ports, the clk_enable_count of the enet1_ref and enet2_ref clocks is not 0. The root cause is that since the commit 985329462723 ("net: phy: micrel: use devm_clk_get_optional_enabled for the rmii-ref clock"), the external clock of KSZ PHY has been enabled when the PHY driver probes, and it can only be disabled when the PHY driver is removed. This causes the clock to continue working when the system is suspended or the network port is down. Although Heiko explained in the commit message that the patch was because some clock suppliers need to enable the clock to get the valid clock rate , it seems that the simple fix is to disable the clock after getting the clock rate to solve the current problem. This is indeed true, but we need to admit that Heiko's patch has been applied for more than a year, and we cannot guarantee whether there are platforms that only enable rmii-ref in the KSZ PHY driver during this period. If this is the case, disabling rmii-ref will cause RMII on these platforms to not work. Secondly, commit 99ac4cbcc2a5 ("net: phy: micrel: allow usage of generic ethernet-phy clock") just simply enables the generic clock permanently, which seems like the generic clock may only be enabled in the PHY driver. If we simply disable the generic clock, RMII may not work. If we keep it as it is, the platform using the generic clock will have the same problem as the i.MX6ULL platform. To solve this problem, the clock is enabled when phy_driver::resume() is called, and the clock is disabled when phy_driver::suspend() is called. Since phy_driver::resume() and phy_driver::suspend() are not called in pairs, an additional clk_enable flag is added. When phy_driver::suspend() is called, the clock is disabled only if clk_enable is true. Conversely, when phy_driver::resume() is called, the clock is enabled if clk_enable is false. The changes that introduced the problem were only a few lines, while the current fix is about a hundred lines, which seems out of proportion, but it is necessary because kszphy_probe() is used by multiple KSZ PHYs and we need to fix all of them.

If something else is going awry, e.g. due to a bug in mmu_notifiers, then treating read faults as spurious in this scenario could effectively mask the underlying problem. However, retrying the faulting access instead of overwriting an existing SPTE is functionally correct and desirable irrespective of the WARN, and fast GUP _can_ legitimately fail with a writable VMA, e.g. if the Accessed bit in primary MMU's PTE is toggled and causes a PTE value mismatch. The WARN was also recently added, specifically to track down scenarios where KVM is unnecessarily overwrites SPTEs, i.e. treating the fault as spurious doesn't regress KVM's bug-finding capabilities in any way. In short, letting the WARN linger because there's a tiny chance it's due to a bug elsewhere would be excessively paranoid.

Otherwise partially updated Audio InfoFrames could be sent out. Two cases where this rule were not followed are fixed: - In adv7511_hdmi_hw_params() make sure AUDIO_UPDATE bit is updated before/after setting ADV7511_REG_AUDIO_INFOFRAME. - In audio_startup() use the correct register for clearing AUDIO_UPDATE bit. The problem with corrupted audio infoframes were discovered by letting a HDMI logic analyser check the output of ADV7535. Note that this patchs replaces writing REG_GC(1) with REG_INFOFRAME_UPDATE. Bit 5 of REG_GC(1) is positioned within field GC_PP[3:0] and that field doesn't control audio infoframe and is read- only. My conclusion therefore was that the author if this code meant to clear bit 5 of REG_INFOFRAME_UPDATE from the very beginning.

As such, the NDO XDP XMIT callback should return early if either of these conditions are false. In the case of no loaded XDP program, priv->num_xdp_queues=0 which can cause a divide-by-zero error, and in the case of interface down, num_xdp_queues remains untouched to persist XDP queue count for the next interface up, but the TX pointer itself would be NULL. The XDP xmit callback also needs to synchronize with a device transitioning from open to close. This synchronization will happen via the GVE_PRIV_FLAGS_NAPI_ENABLED bit along with a synchronize_net() call, which waits for any RCU critical sections at call-time to complete.

In GVE, this NAPI ID will never correspond to a NAPI ID of one of the dedicated XDP TX queues registered with the umem because XDP TX is not set up to share a NAPI with a corresponding RX queue. This patch moves XSK TX descriptor processing from the TX NAPI to the RX NAPI, and the gve_xsk_wakeup callback is updated to use the RX NAPI instead of the TX NAPI, accordingly. The branch on if the wakeup is for TX is removed, as the NAPI poll should be invoked whether the wakeup is for TX or for RX.

As it stands, the number of allocated XDP queues changes in three different scenarios. 1) Adding an XDP program while the interface is up via gve_add_xdp_queues 2) Removing an XDP program while the interface is up via gve_remove_xdp_queues 3) After queues have been allocated and the old queue memory has been removed in gve_queues_start. However, the requirement for the interface to be up for gve_(add|remove)_xdp_queues to be called, in conjunction with the fact that the number of queues stored in priv isn't updated until _after_ XDP queues have been allocated in the normal queue allocation path means that if an XDP program is added while the interface is down, XDP queues won't be added until the _second_ if_up, not the first. Given the expectation that the number of XDP queues is equal to the number of RX queues, scenario (3) has another problematic implication. When changing the number of queues while an XDP program is loaded, the number of XDP queues must be updated as well, as there is logic in the driver (gve_xdp_tx_queue_id()) which relies on every RX queue having a corresponding XDP TX queue. However, the number of XDP queues stored in priv would not be updated until _after_ a close/open leading to a mismatch in the number of XDP queues reported vs the number of XDP queues which actually exist after the queue count update completes. This patch remedies these issues by doing the following: 1) The allocation config getter function is set up to retrieve the _expected_ number of XDP queues to allocate instead of relying on the value stored in `priv` which is only updated once the queues have been allocated. 2) When adjusting queues, XDP queues are adjusted to match the number of RX queues when XDP is enabled. This only works in the case when queues are live, so part (1) of the fix must still be available in the case that queues are adjusted when there is an XDP program and the interface is down.

As a result, except for the global memory limit, the rmem of sk_redir is nearly unlimited. Thus, add sk_rmem_alloc related logic to limit the recv buffer. Since the function sk_msg_recvmsg and __sk_psock_purge_ingress_msg are used in these two paths. We use "msg->skb" to test whether the sk_msg is skb backed up. If it's not, we shall do the memory accounting explicitly.

At the same time, __struct_group() relies on the latters, so when the @TAG argument is not empty, C++ code doesn't want to build (even under `extern "C"`): ../linux/include/uapi/linux/pkt_cls.h:25:24: error: 'struct tc_u32_sel::::tc_u32_sel_hdr,' invalid; an anonymous union may only have public non-static data members [-fpermissive] The safest way to fix this without trying to switch standards (which is impossible in UAPI anyway) etc., is to disable tag declaration for that language. This won't break anything since for now it's not buildable at all. Use a separate definition for __struct_group() when __cplusplus is defined to mitigate the error, including the version from tools/.

After fixing that one, I hit another: ld.lld: error: undefined symbol: push_gpib_event ld.lld: error: undefined symbol: gpib_match_device_path Where push_gpib_event() was also used outside of the file it was defined in, and that file too only was built as a module. Since the directory that nec7210.c is only traversed when CONFIG_GPIB_NEC7210 is set, and the directory with gpib_common.c is only traversed when CONFIG_GPIB_COMMON is set, use those configs as the option to build those modules. When it is an allyesconfig, then they will both be built in and their functions will be available to the other modules that are also built in.

Since the dynamic preemption has been enabled for PREEMPT_RT we have now CONFIG_PREEMPT and CONFIG_PREEMPT_RT set simultaneously. This affects the vermagic strings which comes now PREEMPT with PREEMPT_RT enabled. The PREEMPT_RT module usually can not be loaded on a PREEMPT kernel because some symbols are missing. However if the symbols are fine then it continues and it crashes later. The problem is that the struct module has a different layout and the num_exentries or init members are at a different position leading to a crash later on. This is not necessary caught by the size check in elf_validity_cache_index_mod() because the mem member has an alignment requirement of __module_memory_align which is big enough keep the total size unchanged. Therefore we should keep the string accurate instead of removing it. Move the PREEMPT_RT check before the PREEMPT so that it takes precedence if both symbols are enabled.

The Host Port is configured to dequeue traffic from these Hardware Queues on the basis of priority i.e. as long as traffic exists on a Hardware Queue of a higher priority, the traffic on Hardware Queues of lower priority isn't dequeued. An alternate operation is also supported wherein traffic can be dequeued by the Host Port in a Round-Robin manner. Until commit under Fixes, the am65-cpsw driver enabled a single TX DMA Channel, due to which, unless modified by user via "ethtool", all traffic from Linux is transmitted on DMA Channel 0. Therefore, configuring the Host Port for priority based dequeuing or Round-Robin operation is identical since there is a single DMA Channel. Since commit under Fixes, all 8 TX DMA Channels are enabled by default. Additionally, the default "tc mapping" doesn't take into account the possibility of different traffic profiles which various users might have. This results in traffic starvation at the Host Port due to the priority based dequeuing which has been enabled by default since the inception of the driver. The traffic starvation triggers NETDEV WATCHDOG timeout for all TX DMA Channels that haven't been serviced due to the presence of traffic on the higher priority TX DMA Channels. Fix this by defaulting to Round-Robin dequeuing at the Host Port, which shall ensure that traffic is dequeued from all TX DMA Channels irrespective of the traffic profile. This will address the NETDEV WATCHDOG timeouts. At the same time, users can still switch from Round-Robin to Priority based dequeuing at the Host Port with the help of the "p0-rx-ptype-rrobin" private flag of "ethtool". Users are expected to setup an appropriate "tc mapping" that suits their traffic profile when switching to priority based dequeuing at the Host Port.

The driver read the power status of all channels before toggling the bit of the desired one. Using the power status register as a base value introduced a problem, because only the bit corresponding to the concerned channel ID should be set in the write-only power enable register. This led to cases where disabling power for one channel also powered off other channels. This patch removes the power status read and ensures the value is limited to the bit matching the channel index of the PI.

This results in the CQ sharing the same Ethernet traffic channel n associated with the chosen vector. However, the value of n is often unpredictable, which can introduce complications for interrupt monitoring and verification tools. Moreover, SW steering uses polling rather than event-driven interrupts. Therefore, there is no need to select any MSIX vector other than the existing vector 0 for CQ creation. In light of these factors, and to enhance predictability, we modify the code to consistently select MSIX vector 0 for CQ creation.

This SA is selected through the encoding_sa link parameter. When there are 2 or more active TX SAs configured (encoding_sa=0): ip macsec add macsec0 tx sa 0 pn 1 on key 00 ip macsec add macsec0 tx sa 1 pn 1 on key 00 ... the traffic should be still sent via TX SA 0 as the encoding_sa was not changed. However, the driver ignores the encoding_sa and overrides it to SA 1 by installing the flow steering id of the newly created TX SA into the SCI -> flow steering id hash map. The future packet tx descriptors will point to the incorrect flow steering rule (SA 1). This patch fixes the issue by avoiding the creation of the flow steering rule for an active TX SA that is not the encoding_sa. The driver side tx_sa object and the FW side macsec object are still created. When the encoding_sa link parameter is changed to another active TX SA, only the new flow steering rule will be created in the mlx5e_macsec_upd_txsa() handler.

During profile change, the hardware resources allocated by the old profile will be cleaned up. However, the cleanup is relying on the related kernel modules. And they may need to flush themselves first, which is triggered by netdev events, for example, NETDEV_UNREGISTER. However, netdev is kept, or netdev_register is called after the cleanup, which may cause troubles because the resources are still referred by kernel modules. The same process applies to all the caes when uplink is leaving switchdev mode, including devlink eswitch mode set legacy, driver unload and devlink reload. For the first one, it can be blocked and returns failure to users, whenever possible. But it's hard for the others. Besides, the attachment to nic profile is unnecessary as the netdev will be unregistered anyway for such cases. So in this patch, the original behavior is kept only for devlink eswitch set mode legacy. For the others, moves netdev unregistration before the profile change.

This is because in some paths that call btrfs_cow_block(), such as btrfs_search_slot(), we are holding the last reference on the extent buffer @buf so btrfs_force_cow_block() drops the last reference on the @buf extent buffer when it calls free_extent_buffer_stale(buf), which schedules the release of the extent buffer with RCU. This means that if we are on a kernel with preemption, the current task may be preempted before calling trace_btrfs_cow_block() and the extent buffer already released by the time trace_btrfs_cow_block() is called, resulting in a use-after-free. Fix this by moving the trace_btrfs_cow_block() from btrfs_cow_block() to btrfs_force_cow_block() before the COWed extent buffer is freed. This also has a side effect of invoking the tracepoint in the tree defrag code, at defrag.c:btrfs_realloc_node(), since btrfs_force_cow_block() is called there, but this is fine and it was actually missing there.

In particular, if we are relocating concurrently with aborting a transaction, this can result in a crash like the following: BUG: kernel NULL pointer dereference, address: 0000000000000000 PGD 0 P4D 0 Oops: 0000 [#1] SMP CPU: 76 PID: 1411631 Comm: kworker/u322:5 Workqueue: events_unbound btrfs_reclaim_bgs_work RIP: 0010:set_page_extent_mapped+0x20/0xb0 RSP: 0018:ffffc900516a7be8 EFLAGS: 00010246 RAX: ffffea009e851d08 RBX: ffffea009e0b1880 RCX: 0000000000000000 RDX: 0000000000000000 RSI: ffffc900516a7b90 RDI: ffffea009e0b1880 RBP: 0000000003573000 R08: 0000000000000001 R09: ffff88c07fd2f3f0 R10: 0000000000000000 R11: 0000194754b575be R12: 0000000003572000 R13: 0000000003572fff R14: 0000000000100cca R15: 0000000005582fff FS: 0000000000000000(0000) GS:ffff88c07fd00000(0000) knlGS:0000000000000000 CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 CR2: 0000000000000000 CR3: 000000407d00f002 CR4: 00000000007706f0 DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000 DR3: 0000000000000000 DR6: 00000000fffe0ff0 DR7: 0000000000000400 PKRU: 55555554 Call Trace: ? __die+0x78/0xc0 ? page_fault_oops+0x2a8/0x3a0 ? __switch_to+0x133/0x530 ? wq_worker_running+0xa/0x40 ? exc_page_fault+0x63/0x130 ? asm_exc_page_fault+0x22/0x30 ? set_page_extent_mapped+0x20/0xb0 relocate_file_extent_cluster+0x1a7/0x940 relocate_data_extent+0xaf/0x120 relocate_block_group+0x20f/0x480 btrfs_relocate_block_group+0x152/0x320 btrfs_relocate_chunk+0x3d/0x120 btrfs_reclaim_bgs_work+0x2ae/0x4e0 process_scheduled_works+0x184/0x370 worker_thread+0xc6/0x3e0 ? blk_add_timer+0xb0/0xb0 kthread+0xae/0xe0 ? flush_tlb_kernel_range+0x90/0x90 ret_from_fork+0x2f/0x40 ? flush_tlb_kernel_range+0x90/0x90 ret_from_fork_asm+0x11/0x20 This occurs because cleanup_one_transaction() calls destroy_delalloc_inodes() which calls invalidate_inode_pages2() which takes the folio_lock before setting mapping to NULL.

We are called with the inode's VFS lock acquired, so we won't race with buffered and direct IO writes, however we can still race with memory mapped writes since they don't acquire the inode's VFS lock. The race window is between flushing all delalloc and locking the whole file's extent range, since memory mapped writes lock an extent range with the length of a page. Fix this by acquiring the inode's mmap lock before we flush delalloc.

That helper is meant to be quick because it's used in the NOCOW write path, when flushing delalloc and when doing a direct IO write, however it does return some false positives, meaning it may indicate that an extent is shared even if it's no longer the case. For the write path this is fine, we just do a unnecessary COW operation instead of doing a more rigorous check which would be too heavy (calling btrfs_is_data_extent_shared()). However when activating a swap file, the false positives simply result in a failure, which is confusing for users/applications. One particular case where this happens is when a data extent only has 1 reference but that reference is not inlined in the extent item located in the extent tree - this happens when we create more than 33 references for an extent and then delete those 33 references plus every other non-inline reference except one. The function check_committed_ref() assumes that if the size of an extent item doesn't match the size of struct btrfs_extent_item plus the size of an inline reference (plus an owner reference in case simple quotas are enabled), then the extent is shared - that is not the case however, we can have a single reference but it's not inlined - the reason we do this is to be fast and avoid inspecting non-inline references which may be located in another leaf of the extent tree, slowing down write paths. The following test script reproduces the bug: $ cat test.sh #!/bin/bash DEV=/dev/sdi MNT=/mnt/sdi NUM_CLONES=50 umount $DEV &> /dev/null run_test() { local sync_after_add_reflinks=$1 local sync_after_remove_reflinks=$2 mkfs.btrfs -f $DEV > /dev/null #mkfs.xfs -f $DEV > /dev/null mount $DEV $MNT touch $MNT/foo chmod 0600 $MNT/foo # On btrfs the file must be NOCOW. chattr +C $MNT/foo &> /dev/null xfs_io -s -c "pwrite -b 1M 0 1M" $MNT/foo mkswap $MNT/foo for ((i = 1; i <= $NUM_CLONES; i++)); do touch $MNT/foo_clone_$i chmod 0600 $MNT/foo_clone_$i # On btrfs the file must be NOCOW. chattr +C $MNT/foo_clone_$i &> /dev/null cp --reflink=always $MNT/foo $MNT/foo_clone_$i done if [ $sync_after_add_reflinks -ne 0 ]; then # Flush delayed refs and commit current transaction. sync -f $MNT fi # Remove the original file and all clones except the last. rm -f $MNT/foo for ((i = 1; i < $NUM_CLONES; i++)); do rm -f $MNT/foo_clone_$i done if [ $sync_after_remove_reflinks -ne 0 ]; then # Flush delayed refs and commit current transaction. sync -f $MNT fi # Now use the last clone as a swap file.

Since a file can have many thousands of extents, this can be a very slow operation and it's currently not interruptible. I had a bug during development of a previous patch that resulted in an infinite loop when iterating the extents, so a core was busy looping and I couldn't cancel the operation, which is very annoying and requires a reboot. So make the loop interruptible by checking for fatal signals at the end of each iteration and stopping immediately if there is one.

This means that if after that transaction commit we unmount the filesystem without starting and committing any other transaction, or we have a power failure, the next time we mount the filesystem we will find the flag BTRFS_QGROUP_STATUS_FLAG_SIMPLE_MODE set in the item with the key BTRFS_QGROUP_STATUS_KEY but we will not find the incompat bit BTRFS_FEATURE_INCOMPAT_SIMPLE_QUOTA set in the superblock, triggering an assertion failure at: btrfs_read_qgroup_config() -> qgroup_read_enable_gen() To fix this issue, set the BTRFS_FEATURE_INCOMPAT_SIMPLE_QUOTA flag immediately after setting the BTRFS_QGROUP_STATUS_FLAG_SIMPLE_MODE. This ensures that both flags are flushed to disk within the same transaction.

Besides, it's odd to have this particular exception path tested when there are no other tests that verify that the interface is working at all - e.g. the test would pass if dsp_local_on interface is completely broken and fails on any attempt.

Devices that require a valid stop condition, such as EEPROMs, fail to function correctly as a result. The issue only affects devices with the single-master property enabled. This commit resolves the issue by re-enabling I2C bus busy bit (IBB) polling for single-master mode when generating a stop condition. The fix further ensures that the i2c_imx->stopped flag is cleared at the start of each transfer, allowing the stop condition to be correctly generated in i2c_imx_stop(). According to the reference manual (IMX8MMRM, Rev. 2, 09/2019, page 5270), polling the IBB bit to determine if the bus is free is only necessary in multi-master mode. Consequently, the IBB bit is not polled for the start condition in single-master mode.

The user must reduce the clock speed to obtain the SCL low time to meet the 1.3us I2C minimum required. This behavior means the SoC is not compliant to the I2C spec at 400kHz.

The issue can be reproduced with this command: $ rtla timerlat hist -U -d 1s Index over: count: min: avg: max: Floating point exception (core dumped) (There are always no samples with -U unless the user workload is created.) Fix the bug by omitting max/min/avg when sample count is zero, displaying a dash instead, just like we already do for the individual CPUs. The logic is moved into a new function called format_summary_value, which is used for both the individual CPUs and for the overall summary.

As snap_rcv expects transport_header to point to SNAP header (OID:PID) after LLC processing advances offset over LLC header (llc_rcv & llc_fixup_skb), code doesn't find a match and packet is dropped. Between napi_complete_done and snap_rcv, transport_header is not used until __netif_receive_skb_core, where originally it was being reset. Commit fda55eca5a33 ("net: introduce skb_transport_header_was_set()") only does so if not set, on the assumption the value was set correctly by GRO (and also on assumption that "network stacks usually reset the transport header anyway"). Afterwards it is moved forward by llc_fixup_skb. Locally generated traffic shows up at __netif_receive_skb_core with no transport_header set and is processed without issue. On a setup with GRO but no DSA, transport_header and network_header are both set to point to skb->data which is also correct. As issue is LLC specific, to avoid impacting non-LLC traffic, and to follow up on original assumption made on previous code change, llc_fixup_skb to reset the offset after skb pull. llc_fixup_skb assumes the LLC header is at skb->data, and by definition SNAP header immediately follows.

It's a regression caused with commit 505363957fad ("nvmet: fix nvme status code when namespace is disabled"). The mutex ->su_mutex is used to find whether a disabled nsid exists in the config group or not. This is to differentiate between a nsid that is disabled vs non-existent. To mitigate the above issue, we've worked upon a fix[2] where we now insert nsid in subsys Xarray as soon as it's created under config group and later when that nsid is enabled, we add an Xarray mark on it and set ns->enabled to true. The Xarray mark is useful while we need to loop through all enabled namepsaces under a subsystem using xa_for_each_marked() API. If later a nsid is disabled then we clear Xarray mark from it and also set ns->enabled to false. It's only when nsid is deleted from the config group we delete it from the Xarray. So with this change, now we could easily differentiate a nsid is disabled (i.e. Xarray entry for ns exists but ns->enabled is set to false) vs non- existent (i.e.Xarray entry for ns doesn't exist).

Since binutils commit 1f1b5e506bf0 ("bfd/ELF: restrict file alignment for object files"), the byte offset to each section (sh_offset) in relocatable ELF is no longer guaranteed to be aligned. modpost parses MODULE_DEVICE_TABLE() data structures, which are usually located in the .rodata section. If it is not properly aligned, unaligned access errors may occur. To address the issue, this commit imports the get_unaligned() helper from include/linux/unaligned.h. The get_unaligned_native() helper caters to the endianness in addition to handling the unaligned access. I slightly refactored do_pcmcia_entry() and do_input() to avoid writing back to an unaligned address. (We would need the put_unaligned() helper to do that.) The addend_*_rel() functions need similar adjustments because the .text sections are not aligned either. It seems that the .symtab, .rel.* and .rela.* sections are still aligned. Keep normal pointer access for these sections to avoid unnecessary performance costs.

However, after rewriting the core freezer logic, the frozen task stat is reported as 'R'. This is confusing, especially when a task with stat of 'S' is frozen. This bug can be reproduced with these steps: $ cd /sys/fs/cgroup/freezer/ $ mkdir test $ sleep 1000 & [1] 739 // task whose stat is 'S' $ echo 739 > test/cgroup.procs $ echo FROZEN > test/freezer.state $ ps -aux | grep 739 root 739 0.1 0.0 8376 1812 pts/0 R 10:56 0:00 sleep 1000 As shown above, a task whose stat is 'S' was changed to 'R' when it was frozen. To solve this regression, simply maintain the same reported state as before the rewrite.

When the decoder finds an inappropriate instruction while WFE is set ENDBR, the CPU raises a #CP fault. For the "kernel IBT no ENDBR" selftest where #CPs are deliberately triggered, the WFE state of the interrupted context needs to be cleared to let execution continue. Otherwise when the CPU resumes from the instruction that just caused the previous #CP, another missing-ENDBRANCH #CP is raised and the CPU enters a dead loop. This is not a problem with IDT because it doesn't preserve WFE and IRET doesn't set WFE. But FRED provides space on the entry stack (in an expanded CS area) to save and restore the WFE state, thus the WFE state is no longer clobbered, so software must clear it. Clear WFE to avoid dead looping in ibt_clear_fred_wfe() and the !ibt_fatal code path when execution is allowed to continue. Clobbering WFE in any other circumstance is a security-relevant bug.

For instance, SilverBench (https://silver.urih.com/) results improved from ~56,000 to ~69,000, as a result of higher power draws (and thus core frequencies) whilst under load: Package Power: - Before the patch: ~65W (dropping to about 55W under sustained load). - After the patch: ~115W (dropping to about 105W under sustained load).

Although it's fine to filter the invalid UMP groups at the first probe time, this will become a problem when UMP groups are updated and (re-)activated. Then there is no way to re-add the substreams properly for the legacy rawmidi, and the new active groups will be still invisible. So let's revert the change. This will move back to showing the full 16 groups, but it's better than forever lost.

This is necessary because the TX NAPI only processes TX completions, meaning that a TX wakeup would not actually trigger XSK descriptor processing. Also, the branch on XDP_WAKEUP_TX was supposed to have been removed, as the NAPI should be scheduled whether the wakeup is for RX or TX.

The root cause is a buggy MPTCP option len computation in some circumstances: the ADD_ADDR option should be mutually exclusive with DSS since the blamed commit. Still, mptcp_established_options_add_addr() tries to set the relevant info in mptcp_out_options, if the remaining space is large enough even when DSS is present. Since the ADD_ADDR infos and the DSS share the same union fields, adding first corrupts the latter. In the worst-case scenario, such corruption increases the DSS binary layout, exceeding the computed length and possibly overwriting the skb shared info. Address the issue by enforcing mutual exclusion in mptcp_established_options_add_addr(), too.

In commit 158978945f31 ("mm: perform the mapping_map_writable() check after call_mmap()") (and preceding changes in the same series) it became possible to mmap() F_SEAL_WRITE sealed memfd mappings read-only. Commit 5de195060b2e ("mm: resolve faulty mmap_region() error path behaviour") unintentionally undid this logic by moving the mapping_map_writable() check before the shmem_mmap() hook is invoked, thereby regressing this change. This series reworks how we both permit write-sealed mappings being mapped read-only and disallow mprotect() from undoing the write-seal, fixing this regression. We also add a regression test to ensure that we do not accidentally regress this in future. Thanks to Julian Orth for reporting this regression. This patch (of 2): In commit 158978945f31 ("mm: perform the mapping_map_writable() check after call_mmap()") (and preceding changes in the same series) it became possible to mmap() F_SEAL_WRITE sealed memfd mappings read-only. This was previously unnecessarily disallowed, despite the man page documentation indicating that it would be, thereby limiting the usefulness of F_SEAL_WRITE logic. We fixed this by adapting logic that existed for the F_SEAL_FUTURE_WRITE seal (one which disallows future writes to the memfd) to also be used for F_SEAL_WRITE. For background - the F_SEAL_FUTURE_WRITE seal clears VM_MAYWRITE for a read-only mapping to disallow mprotect() from overriding the seal - an operation performed by seal_check_write(), invoked from shmem_mmap(), the f_op->mmap() hook used by shmem mappings. By extending this to F_SEAL_WRITE and critically - checking mapping_map_writable() to determine if we may map the memfd AFTER we invoke shmem_mmap() - the desired logic becomes possible. This is because mapping_map_writable() explicitly checks for VM_MAYWRITE, which we will have cleared. Commit 5de195060b2e ("mm: resolve faulty mmap_region() error path behaviour") unintentionally undid this logic by moving the mapping_map_writable() check before the shmem_mmap() hook is invoked, thereby regressing this change. We reinstate this functionality by moving the check out of shmem_mmap() and instead performing it in do_mmap() at the point at which VMA flags are being determined, which seems in any case to be a more appropriate place in which to make this determination. In order to achieve this we rework memfd seal logic to allow us access to this information using existing logic and eliminate the clearing of VM_MAYWRITE from seal_check_write() which we are performing in do_mmap() instead.

Additionally, since this system lacks swap, the calculation of inactive/ active anonymous pages is skipped. crash> p nr_swap_pages nr_swap_pages = $1937 = { counter = 0 } As a result, ZONE_DMA32 is deemed unreclaimable and skipped, moving on to the processing of the next zone, ZONE_NORMAL, despite ZONE_DMA32 having free pages significantly exceeding the high watermark. The problem is that the pgdat->kswapd_failures hasn't been incremented. crash> px ((struct pglist_data *) 0xffff00817fffe540)->kswapd_failures $1935 = 0x0 This is because the node deemed balanced. The node balancing logic in balance_pgdat() evaluates all zones collectively. If one or more zones (e.g., ZONE_DMA32) have enough free pages to meet their watermarks, the entire node is deemed balanced. This causes balance_pgdat() to exit early before incrementing the kswapd_failures, as it considers the overall memory state acceptable, even though some zones (like ZONE_NORMAL) remain under significant pressure. The patch ensures that zone_reclaimable_pages() includes free pages (NR_FREE_PAGES) in its calculation when no other reclaimable pages are available (e.g., file-backed or anonymous pages). This change prevents zones like ZONE_DMA32, which have sufficient free pages, from being mistakenly deemed unreclaimable. By doing so, the patch ensures proper node balancing, avoids masking pressure on other zones like ZONE_NORMAL, and prevents infinite loops in throttle_direct_reclaim() caused by allow_direct_reclaim(pgdat) repeatedly returning false. The kernel hangs due to a task stuck in throttle_direct_reclaim(), caused by a node being incorrectly deemed balanced despite pressure in certain zones, such as ZONE_NORMAL. This issue arises from zone_reclaimable_pages() returning 0 for zones without reclaimable file- backed or anonymous pages, causing zones like ZONE_DMA32 with sufficient free pages to be skipped. The lack of swap or reclaimable pages results in ZONE_DMA32 being ignored during reclaim, masking pressure in other zones. Consequently, pgdat->kswapd_failures remains 0 in balance_pgdat(), preventing fallback mechanisms in allow_direct_reclaim() from being triggered, leading to an infinite loop in throttle_direct_reclaim(). This patch modifies zone_reclaimable_pages() to account for free pages (NR_FREE_PAGES) when no other reclaimable pages exist. This ensures zones with sufficient free pages are not skipped, enabling proper balancing and reclaim behavior.

This leads to us always trying THP alignment even for file_operations which have a NULL ->get_unmapped_area() callback. Since commit efa7df3e3bb5 ("mm: align larger anonymous mappings on THP boundaries") we only want to enable THP alignment for anonymous mappings, so add a !file check to avoid attempting THP alignment for file mappings. Found issue by code inspection. THP alignment is used for easy or more pmd mappings, from vma side. This may cause unnecessary VMA fragmentation and potentially worse performance on filesystems that do not actually support THPs and thus cannot benefit from the alignment.

After a thorough analysis, I identified it was caused by the `/sys/block/*/queue/read_ahead_kb` setting. On our test servers, this parameter is set to 128KB. After I tune it to 2MB, the large folio can work as expected. However, I believe the large folio behavior should not be dependent on the value of read_ahead_kb. It would be more robust if the kernel can automatically adopt to it. With /sys/block/*/queue/read_ahead_kb set to 128KB and performing a sequential read on a 1GB file using MADV_HUGEPAGE, the differences in /proc/meminfo are as follows: - before this patch FileHugePages: 18432 kB FilePmdMapped: 4096 kB - after this patch FileHugePages: 1067008 kB FilePmdMapped: 1048576 kB This shows that after applying the patch, the entire 1GB file is mapped to huge pages. The stable list is CCed, as without this patch, large folios don't function optimally in the readahead path. It's worth noting that if read_ahead_kb is set to a larger value that isn't aligned with huge page sizes (e.g., 4MB + 128KB), it may still fail to map to hugepages.

Additionally, %pK requires a privilege check CAP_SYSLOG enforced through the LSM, which can trigger a "sleeping function called from invalid context" warning under RT_PREEMPT kernels when the check occurs in an atomic context. This issue may also affect other LSMs. This change avoids the unnecessary privilege check and resolves the sleeping function warning without any loss of information.

Specifically, sb_dqinfo(sb, type)->dqi_priv is the dangling pointer. During the remounting process, the pointer dqi_priv is freed but is never set as null leaving it to be accessed. Additionally, the read-only option for remounting sets the DQUOT_SUSPENDED flag instead of setting the DQUOT_USAGE_ENABLED flags. Moreover, later in the process of getting the next quota, the function ocfs2_get_next_id is called and only checks the quota usage flags and not the quota suspended flags. To fix this, I set dqi_priv to null when it is freed after remounting with read-only and put a check for DQUOT_SUSPENDED in ocfs2_get_next_id.

However, since neither preemption nor migration are disabled, it is possible that the operation continues on a different CPU. If the original CPU is hotunplugged while the acomp_ctx is still in use, we run into a UAF bug as the resources attached to the acomp_ctx are freed during hotunplug in zswap_cpu_comp_dead(). The problem was introduced in commit 1ec3b5fe6eec ("mm/zswap: move to use crypto_acomp API for hardware acceleration") when the switch to the crypto_acomp API was made. Prior to that, the per-CPU crypto_comp was retrieved using get_cpu_ptr() which disables preemption and makes sure the CPU cannot go away from under us. Preemption cannot be disabled with the crypto_acomp API as a sleepable context is needed. Commit 8ba2f844f050 ("mm/zswap: change per-cpu mutex and buffer to per-acomp_ctx") increased the UAF surface area by making the per-CPU buffers dynamic, adding yet another resource that can be freed from under zswap compression/decompression by CPU hotunplug. There are a few ways to fix this: (a) Add a refcount for acomp_ctx. (b) Disable migration while using the per-CPU acomp_ctx. (c) Disable CPU hotunplug while using the per-CPU acomp_ctx by holding the CPUs read lock. Implement (c) since it's simpler than (a), and (b) involves using migrate_disable() which is apparently undesired (see huge comment in include/linux/preempt.h).

This will make item counter uncharging happen in the parent while the item is still being held by the child. As a result, the parent's counter value may become negative. This is acceptable because re-parenting will sum up the children's counter values, and the parent's counter will be fixed. Later commit fb56fdf8b9a2 ("mm/list_lru: split the lock to per-cgroup scope") reworked the re-parenting process, and removed the redirect. So it added the sanity check back, assuming that as long as items are still in the children's list_lru, parent's counter will not be uncharged. But that assumption is incorrect. The xas_store in memcg_reparent_list_lrus will set children's list_lru to NULL before re-parenting the items, it redirects list_lru helpers to use parent's list_lru just like before. But still, it's not a problem as re-parenting will fix the counter. Therefore, remove this sanity check, but add a new check to ensure that the counter won't go negative in a different way: the child's list_lru being re-parented should never have a negative counter, since re-parenting should occur in order and fixes counters.

Due to two bugs in damon_commit_targets() and damon_commit_schemes(), which are called from damon_commit_ctx(), some user inputs can be ignored, and some mmeory objects can be leaked. Fix those. Note that only DAMON sysfs interface users are affected. Other DAMON core API user modules that more focused more on simple and dedicated production usages, including DAMON_RECLAIM and DAMON_LRU_SORT are not using the buggy function in the way, so not affected. This patch (of 2): When new DAMON targets are added via damon_commit_targets(), the newly created targets are not deallocated when updating the internal data (damon_commit_target()) is failed. Worse yet, even if the setup is successfully done, the new target is not linked to the context. Hence, the new targets are always leaked regardless of the internal data setup failure. Fix the leaks.

For workingset shadow nodes (which are xa_node), users are converted to use the new infrastructure by commit 9bbdc0f32409 ("xarray: use kmem_cache_alloc_lru to allocate xa_node"). The xas->xa_lru will be set correctly for filemap users. However, there is a missing case: xa_node allocations caused by madvise(..., MADV_COLLAPSE). madvise(..., MADV_COLLAPSE) will also read in the absent parts of file map, and there will be xa_nodes allocated for the caller's memcg (assuming it's not rootcg). However, these allocations won't trigger memcg list_lru allocation because the proper xas info was not set. If nothing else has allocated other xa_nodes for that memcg to trigger list_lru creation, and memory pressure starts to evict file pages, workingset_update_node will try to add these xa_nodes to their corresponding memcg list_lru, and it does not exist (NULL). So they will be added to rootcg's list_lru instead. This shouldn't be a significant issue in practice, but it is indeed unexpected behavior, and these xa_nodes will not be reclaimed effectively. And may lead to incorrect counting of the list_lru->nr_items counter. This problem wasn't exposed until recent commit 28e98022b31ef ("mm/list_lru: simplify reparenting and initial allocation") added a sanity check: only dying memcg could have a NULL list_lru when list_lru_{add,del} is called. This problem triggered this WARNING. So make madvise(..., MADV_COLLAPSE) also call xas_set_lru() to pass the list_lru which we may want to insert xa_node into later. And move mapping_set_update to mm/internal.h, and turn into a macro to avoid including extra headers in mm/internal.h.

This can lead to undefined behavior and incorrect sorting results, potentially causing memory corruption in glibc implementations [1]. Symmetry: If x < y, then y > x.

Each commit message is retained for reference. 1) Allow a GGTT mapped batch to be submitted to user exec queue For a OA use case, one of the HW registers needs to be modified by submitting an MI_LOAD_REGISTER_IMM command to the users exec queue, so that the register is modified in the user's hardware context. In order to do this a batch that is mapped in GGTT, needs to be submitted to the user exec queue. Since all user submissions use q->vm and hence PPGTT, add some plumbing to enable submission of batches mapped in GGTT. v2: ggtt is zero-initialized, so no need to set it false (Matt Brost) 2) xe/oa: Use MI_LOAD_REGISTER_IMMEDIATE to enable OAR/OAC To enable OAR/OAC, a bit in RING_CONTEXT_CONTROL needs to be set. Setting this bit cause the context image size to change and if not done correct, can cause undesired hangs. Current code uses a separate exec_queue to modify this bit and is error-prone. As per HW recommendation, submit MI_LOAD_REGISTER_IMM to the target hardware context to modify the relevant bit. In v2 version, an attempt to submit everything to the user-queue was made, but it failed the unprivileged-single-ctx-counters test. It appears that the OACTXCONTROL must be modified from a remote context. In v3 version, all context specific register configurations were moved to use LOAD_REGISTER_IMMEDIATE and that seems to work well. This is a cleaner way, since we can now submit all configuration to user exec_queue and the fence handling is simplified. v2: (Matt) - set job->ggtt to true if create job is successful - unlock vm on job error (Ashutosh) - don't wait on job submission - use kernel exec queue where possible v3: (Ashutosh) - Fix checkpatch issues - Remove extra spaces/new-lines - Add Fixes: and Cc: tags - Reset context control bit when OA stream is closed - Submit all config via MI_LOAD_REGISTER_IMMEDIATE (Umesh) - Update commit message for v3 experiment - Squash patches for easier port to stable v4: (Ashutosh) - No need to pass q to xe_oa_submit_bb - Do not support exec queues with width > 1 - Fix disabling of CTX_CTRL_OAC_CONTEXT_ENABLE v5: (Ashutosh) - Drop reg_lri related comments - Use XE_OA_SUBMIT_NO_DEPS in xe_oa_load_with_lri Fixes: 8135f1c09dd2 ("drm/xe/oa: Don't reset OAC_CONTEXT_ENABLE on OA stream close") Signed-off-by: Umesh Nerlige Ramappa Reviewed-by: Matthew Brost # commit 1 Reviewed-by: Ashutosh Dixit Cc: stable@vger.kernel.org Reviewed-by: Jonathan Cavitt Signed-off-by: Ashutosh Dixit Link: https://patchwork.freedesktop.org/patch/msgid/20241220171919.571528-2-umesh.nerlige.ramappa@intel.com (cherry picked from commit 55039832f98c7e05f1cf9e0d8c12b2490abd0f16) Signed-off-by: Thomas Hellström --- drivers/gpu/drm/xe/xe_oa.c | 134 ++++++++---------------- drivers/gpu/drm/xe/xe_ring_ops.c | 5 +- drivers/gpu/drm/xe/xe_sched_job_types.h | 2 + 3 files changed, 51 insertions(+), 90 deletions(-) diff --git a/drivers/gpu/drm/xe/xe_oa.c b/drivers/gpu/drm/xe/xe_oa.c index 8dd55798ab312..5cc0f6f9bc113 100644 --- a/drivers/gpu/drm/xe/xe_oa.c +++ b/drivers/gpu/drm/xe/xe_oa.c @@ -74,12 +74,6 @@ struct xe_oa_config { struct rcu_head rcu;

The loop checks if an element is a fgraph_stub to prevent using a fgraph_stub afterward. However, if the compiler reloads fgraph_array[] after this check, it might race with an update to fgraph_array[] that introduces a fgraph_stub. This could result in the stub being processed, but the stub contains a null "func_hash" field, leading to a NULL pointer dereference. To ensure that the gops compared against the fgraph_stub matches the gops processed later, add a READ_ONCE().

While tracers are instantiated, the function profiler is not. Therefore, it should use the global set_ftrace_filter for consistency. This patch modifies the function profiler to use the global filter, fixing the filtering functionality.

Timesync related operations are ran in PRU0 cores for both ICSSG SLICE0 and SLICE1. Currently whenever any ICSSG interface comes up we load the respective firmwares to PRU cores and whenever interface goes down, we stop the resective cores. Due to this, when SLICE0 goes down while SLICE1 is still active, PRU0 firmwares are unloaded and PRU0 core is stopped. This results in clock jump for SLICE1 interface as the timesync related operations are no longer running. As there are interdependencies between SLICE0 and SLICE1 firmwares, fix this by running both PRU0 and PRU1 firmwares as long as at least 1 ICSSG interface is up. Add new flag in prueth struct to check if all firmwares are running and remove the old flag (fw_running). Use emacs_initialized as reference count to load the firmwares for the first and last interface up/down. Moving init_emac_mode and fw_offload_mode API outside of icssg_config to icssg_common_start API as they need to be called only once per firmware boot. Change prueth_emac_restart() to return error code and add error prints inside the caller of this functions in case of any failures. Move prueth_emac_stop() from common to sr1 driver. sr1 and sr2 drivers have different logic handling for stopping the firmwares. While sr1 driver is dependent on emac structure to stop the corresponding pru cores for that slice, for sr2 all the pru cores of both the slices are stopped and is not dependent on emac. So the prueth_emac_stop() function is no longer common and can be moved to sr1 driver.

Hence it is expected that the IEP_CMP_CFG register needs to be flushed during iep_init() to ensure that the existing residual configuration doesn't cause any unusual behavior. If the register is not cleared, existing IEP_CMP_CFG set for CMP1 will result in SYNC0_OUT signal based on the SYNC_OUT register values. After bringing the interface up, calling PPS enable doesn't work as the driver believes PPS is already enabled, (iep->pps_enabled is not cleared during interface bring down) and driver will just return true even though there is no signal. Fix this by disabling pps and perout. Fixes: c1e0230eeaab ("net: ti: icss-iep: Add IEP driver") Signed-off-by: Meghana Malladi Reviewed-by: Roger Quadros Signed-off-by: David S.

This is fine, but io_ring_buffer_select() will return the address of the buffer after having committed it. For incrementally consumed buffers, this is incorrect as it will modify the buffer address. Store the pre-committed value and return that. If that isn't done, then the initial part of the buffer is not used and the application will correctly assume the content arrived at the start of the userspace buffer, but the kernel will have put it later in the buffer. Or it can cause a spurious -EFAULT returned in the CQE, depending on the buffer size. As bounds are suitably checked for doing the actual IO, no adverse side effects are possible - it's just a data misplacement within the existing buffer.

Transfers must be observed at a frequency which fits both (so in practice, the lowest maximum). Actually, this second point mixes two information and already takes the lowest frequency among: - what the spi device is capable of (what is written in the component datasheet) - what the wiring allows (electromagnetic sensibility, crossovers, terminations, antenna effect, etc). This logic works until spi devices are no longer capable of sustaining their highest frequency regardless of the operation. Spi memories are typically subject to such variation. Some devices are capable of spitting their internally stored data (essentially in read mode) at a very fast rate, typically up to 166MHz on Winbond SPI-NAND chips, using "fast" commands. However, some of the low-end operations, such as regular page read-from-cache commands, are more limited and can only be executed at 54MHz at most. This is currently a problem in the SPI-NAND subsystem. Another situation, even if not yet supported, will be with DTR commands, when the data is latched on both edges of the clock. The same chips as mentioned previously are in this case limited to 80MHz. Yet another example might be continuous reads, which, under certain circumstances, can also run at most at 104 or 120MHz. As a matter of fact, the "one frequency per chip" policy is outdated and more fine grain configuration is needed: we need to allow per-operation frequency limitations. So far, all datasheets I encountered advertise a maximum default frequency, which need to be lowered for certain specific operations. So based on the current infrastructure, we can still expect firmware (device trees in general) to continued advertising the same maximum speed which is a mix between the PCB limitations and the chip maximum capability, and expect per-operation lower frequencies when this is relevant. Add a `struct spi_mem_op` member to carry this information. Not providing this field explicitly from upper layers means that there is no further constraint and the default spi device maximum speed will be carried instead. The SPI_MEM_OP() macro is also expanded with an optional frequency argument, because virtually all operations can be subject to such a limitation, and this will allow for a smooth and discrete transition. For controller drivers which do not implement the spi-mem interface, the per-transfer speed is also set acordingly to a lower (than the maximum default) speed when relevant.

We probably do not want to afford running at the lowest supported frequency all the time, so if we want to get the most of our hardware, we need to allow per-operation frequency limitations. Among all the SPI memory controllers, I believe all are capable of changing the spi frequency on the fly. Some of the drivers do not make any frequency setup though. And some others will derive a per chip prescaler value which will be used forever. Actually changing the frequency on the fly is something new in Linux, so we need to carefully flag the drivers which do and do not support it. A controller capability is created for that, and the presence for this capability will always be checked before accepting such pattern.

This kind of logic only works if all operations run at the same frequency, but as soon as we introduce per operation max frequencies it is not longer as obvious which operation will be faster, especially since it also depends on the PCB/controller frequency limitation. One way to make this choice more clever is to go over all the variants and for each of them derive an indicator which will help derive the theoretical best. In this case, we derive a theoretical duration for the entire operation and we take the smallest one. Add a helper that parses the spi-mem operation and returns this value.

In practice, without frequency change on the bus, this was likely without effect, besides perhaps allowing another variant of the same command, that could run at the default highest speed. If we want to support this fully, we need to add a frequency parameter to the slowest command. But before we do that, let's drop the "fast" boolean from the macro and duplicate it, this will further help supporting having different frequencies allowed for each variant. The change is also of course propagated to all users. It has the nice effect to have all macros aligned on the same pattern.

There is one drawback though, the slowest READ_FROM_CACHE command cannot run above 54MHz. Because of that, we need to set a limit for these chips on the basic READ_FROM_CACHE variant. Duplicating this list is not a problem because these chips have DTR support, and the list of supported variants will diverge from all the other chips when adding support for it.
