[PATCH 2/6] drm/buddy: fix range bias

by Matthew Auld

There is a corner case here where start/end is after/before the block range we are currently checking. If so we need to be sure that splitting the block will eventually give use the block size we need. To do that we should adjust the block range to account for the start/end, and only continue with the split if the size/alignment will fit the requested size. Not doing so can result in leaving split blocks unmerged when it eventually fails.

[PATCH 5.10.y] bpf: Convert BPF_DISPATCHER to use static_call() (not ftrace)

by kovalev＠altlinux.org

From: Peter Zijlstra <peterz(a)infradead.org> [ Upstream commit c86df29d11dfba27c0a1f5039cd6fe387fbf4239 ] The dispatcher function is currently abusing the ftrace __fentry__ call location for its own purposes -- this obviously gives trouble when the dispatcher and ftrace are both in use. A previous solution tried using __attribute__((patchable_function_entry())) which works, except it is GCC-8+ only, breaking the build on the earlier still supported compilers. Instead use static_call() -- which has its own annotations and does not conflict with ftrace -- to rewrite the dispatch function. By using: return static_call()(ctx, insni, bpf_func) you get a perfect forwarding tail call as function body (iow a single jmp instruction).

[PATCH 5.15.y] bpf: Convert BPF_DISPATCHER to use static_call() (not ftrace)

by kovalev＠altlinux.org

From: Peter Zijlstra <peterz(a)infradead.org> [ Upstream commit c86df29d11dfba27c0a1f5039cd6fe387fbf4239 ] The dispatcher function is currently abusing the ftrace __fentry__ call location for its own purposes -- this obviously gives trouble when the dispatcher and ftrace are both in use. A previous solution tried using __attribute__((patchable_function_entry())) which works, except it is GCC-8+ only, breaking the build on the earlier still supported compilers. Instead use static_call() -- which has its own annotations and does not conflict with ftrace -- to rewrite the dispatch function. By using: return static_call()(ctx, insni, bpf_func) you get a perfect forwarding tail call as function body (iow a single jmp instruction). By having the default static_call() target be bpf_dispatcher_nop_func() it retains the default behaviour (an indirect call to the argument function). Only once a dispatcher program is attached is the target rewritten to directly call the JIT'ed image.

[PATCH net 1/3] can: j1939: prevent deadlock by changing j1939_socks_lock to rwlock

by Marc Kleine-Budde

From: Ziqi Zhao <astrajoan(a)yahoo.com> The following 3 locks would race against each other, causing the deadlock situation in the Syzbot bug report: - j1939_socks_lock - active_session_list_lock - sk_session_queue_lock A reasonable fix is to change j1939_socks_lock to an rwlock, since in the rare situations where a write lock is required for the linked list that j1939_socks_lock is protecting, the code does not attempt to acquire any more locks. This would break the circular lock dependency, where, for example, the current thread already locks j1939_socks_lock and attempts to acquire sk_session_queue_lock, and at the same time, another thread attempts to acquire j1939_socks_lock while holding sk_session_queue_lock. NOTE: This patch along does not fix the unregister_netdevice bug reported by Syzbot; instead, it solves a deadlock situation to prepare for one or more further patches to actually fix the Syzbot bug, which appears to be a reference counting problem within the j1939 codebase.

[PATCH 4.19 5.4 5.10 5.15 6.1 6.6 6.7] nilfs2: fix data corruption in dsync block recovery for small block sizes

by Ryusuke Konishi

commit 67b8bcbaed4777871bb0dcc888fb02a614a98ab1 upstream. The helper function nilfs_recovery_copy_block() of nilfs_recovery_dsync_blocks(), which recovers data from logs created by data sync writes during a mount after an unclean shutdown, incorrectly calculates the on-page offset when copying repair data to the file's page cache. In environments where the block size is smaller than the page size, this flaw can cause data corruption and leak uninitialized memory bytes during the recovery process. Fix these issues by correcting this byte offset calculation on the page.

[PATCH v3] soc: qcom: rpmh-rsc: Enhance check for VRM in-flight request

by Maulik Shah

Each RPMh VRM accelerator resource has 3 or 4 contiguous 4-byte aligned addresses associated with it. These control voltage, enable state, mode, and in legacy targets, voltage headroom. The current in-flight request checking logic looks for exact address matches. Requests for different addresses of the same RPMh resource as thus not detected as in-flight. Add new cmd-db API cmd_db_match_resource_addr() to enhance the in-flight request check for VRM requests by ignoring the address offset. This ensures that only one request is allowed to be in-flight for a given VRM resource. This is needed to avoid scenarios where request commands are carried out by RPMh hardware out-of-order leading to LDO regulator over-current protection triggering.

[PATCH] scsi: core: Consult supported VPD page list prior to fetching page

by Martin K. Petersen

Commit c92a6b5d6335 ("scsi: core: Query VPD size before getting full page") removed the logic which checks whether a VPD page is present on the supported pages list before asking for the page itself. That was done because SPC helpfully states "The Supported VPD Pages VPD page list may or may not include all the VPD pages that are able to be returned by the device server". Testing had revealed a few devices that supported some of the 0xBn pages but didn't actually list them in page 0. Julian Sikorski bisected a problem with his drive resetting during discovery to the commit above. As it turns out, this particular drive firmware will crash if we attempt to fetch page 0xB9. Various approaches were attempted to work around this. In the end, reinstating the logic that consults VPD page 0 before fetching any other page was the path of least resistance.

[PATCH] wifi: nl80211: reject iftype change with mesh ID change

by Johannes Berg

From: Johannes Berg <johannes.berg(a)intel.com> It's currently possible to change the mesh ID when the interface isn't yet in mesh mode, at the same time as changing it into mesh mode. This leads to an overwrite of data in the wdev->u union for the interface type it currently has, causing cfg80211_change_iface() to do wrong things when switching. We could probably allow setting an interface to mesh while setting the mesh ID at the same time by doing a different order of operations here, but realistically there's no userspace that's going to do this, so just disallow changes in iftype when setting mesh ID.

From: Wayne Lin <wayne.lin(a)amd.com> [Why] Observe error message "Can't retrieve aconnector in hpd_rx_irq_offload_work" when boot up with a mst tbt4 dock connected.

[PATCH 3/3] btrfs: dev-replace: properly validate device names

There's a syzbot report that device name buffers passed to device replace are not properly checked for string termination which could lead to a read out of bounds in getname_kernel(). Add a helper that validates both source and target device name buffers. For devid as the source initialize the buffer to empty string in case something tries to read it later. This was originally analyzed and fixed in a different way by Edward Adam Davis (see links).

[PATCH 4.19 5.4 5.10 5.15 6.1] nilfs2: fix hang in nilfs_lookup_dirty_data_buffers()

by Ryusuke Konishi

commit 38296afe3c6ee07319e01bb249aa4bb47c07b534 upstream. Syzbot reported a hang issue in migrate_pages_batch() called by mbind() and nilfs_lookup_dirty_data_buffers() called in the log writer of nilfs2. While migrate_pages_batch() locks a folio and waits for the writeback to complete, the log writer thread that should bring the writeback to completion picks up the folio being written back in nilfs_lookup_dirty_data_buffers() that it calls for subsequent log creation and was trying to lock the folio. Thus causing a deadlock. In the first place, it is unexpected that folios/pages in the middle of writeback will be updated and become dirty. Nilfs2 adds a checksum to verify the validity of the log being written and uses it for recovery at mount, so data changes during writeback are suppressed. Since this is broken, an unclean shutdown could potentially cause recovery to fail. Investigation revealed that the root cause is that the wait for writeback completion in nilfs_page_mkwrite() is conditional, and if the backing device does not require stable writes, data may be modified without waiting. Fix these issues by making nilfs_page_mkwrite() wait for writeback to finish regardless of the stable write requirement of the backing device.

[REGRESSION] Acp5x probing regression introduced between kernel 6.7.2 -> 6.7.4

by Ted Chang

Hi kernel maintainers, I noticed 6.7.4 has introduced a regression for the steam deck. The LCD steam deck can no longer probe the acp5x audio chipset anymore. This regression does not affect the 6.8.x series. I did not test kernel 6.7.3 because Opensuse tumbleweed skipped the update on my machine. Steps to reproduce the problem 1. Obtain a steam deck 2. Install kernel 6.7.4 3. Boot the device and you will see dummy output in gnome shell Observed kernel logs.

[PATCH v2 1/2] drm/buddy: Fix alloc_range() error handling code

by Arunpravin Paneer Selvam

Few users have observed display corruption when they boot the machine to KDE Plasma or playing games. We have root caused the problem that whenever alloc_range() couldn't find the required memory blocks the function was returning SUCCESS in some of the corner cases. The right approach would be if the total allocated size is less than the required size, the function should return -ENOSPC.

[PATCH] scsi: sd: usb_storage: uas: Access media prior to querying device properties

by Martin K. Petersen

It has been observed that some USB/UAS devices return generic properties hardcoded in firmware for mode pages and vital product data for a period of time after a device has been discovered. The reported properties are either garbage or they do not accurately reflect the properties of the physical storage device attached in the case of a bridge. Prior to commit 1e029397d12f ("scsi: sd: Reorganize DIF/DIX code to avoid calling revalidate twice") we would call revalidate several times during device discovery. As a result, incorrect values would eventually get replaced with ones accurately describing the attached storage. When we did away with the redundant revalidate pass, several cases were reported where devices reported nonsensical values or would end up in write-protected state. An initial attempt at addressing this issue involved introducing a delayed second revalidate invocation. However, this approach still left some devices reporting incorrect characteristics. Tasos Sahanidis debugged the problem further and identified that introducing a READ operation prior to MODE SENSE fixed the problem and that it wasn't a timing issue. Issuing a READ appears to cause the devices to update their SCSI pages to reflect the actual properties of the storage media. Device properties like vendor, model, and storage capacity appear to be correctly reported from the get-go. It is unclear why these device defer populating the remaining characteristics. Match the behavior of a well known commercial operating system and trigger a READ operation prior to querying device characteristics to force the device to populate mode pages and VPDs. The additional READ is triggered by a flag set in the USB storage and UAS drivers. We avoid issuing the READ for other transport classes since some storage devices identify Linux through our particular discovery command sequence.

[PATCH 5.15 0/1] ext4, jbd2: add an optimized bmap for the journal inode

by Nikolay Kuratov

It's already into 6.6 and fixes the Syzkaller issue Link: https://syzkaller.appspot.com/bug?id=e4aaa78795e490421c79f76ec3679006c8ff4c… Theoretically the issue boils down to commit 51ae846cff56 ("ext4: fix warning in ext4_iomap_begin as race between bmap and write") so it should be in 5.10, 5.15 and 6.1 kernels. But we at Linux Verification Center can reproduce it with 5.15 and 6.1 only so I'm asking to apply the fix for those two.

[PATCH] comedi: comedi_test: Prevent timers rescheduling during deletion

by Ian Abbott

The comedi_test devices have a couple of timers (ai_timer and ao_timer) that can be started to simulate hardware interrupts. Their expiry functions normally reschedule the timer. The driver code calls either del_timer_sync() or del_timer() to delete the timers from the queue, but does not currently prevent the timers from rescheduling themselves so synchronized deletion may be ineffective. Add a couple of boolean members (one for each timer: ai_timer_enable and ao_timer_enable) to the device private data structure to indicate whether the timers are allowed to reschedule themselves. Set the member to true when adding the timer to the queue, and to false when deleting the timer from the queue in the waveform_ai_cancel() and waveform_ao_cancel() functions. The del_timer_sync() function is also called from the waveform_detach() function, but the timer enable members will already be set to false when that function is called, so no change is needed there.

[PATCH -fixes v3 2/2] riscv: Save/restore envcfg CSR during CPU suspend

by Samuel Holland

The value of the [ms]envcfg CSR is lost when entering a nonretentive idle state, so the CSR must be rewritten when resuming the CPU. The [ms]envcfg CSR was added in version 1.12 of the privileged ISA, and is used by extensions other than Zicboz. However, the kernel currenly has no way to determine the privileged ISA version. Since Zicboz is the only in-kernel user of this CSR so far, use it as a proxy for determining if the CSR is implemented.

[PATCH 1/2] drm/buddy: Fix alloc_range() error handling code

by Arunpravin Paneer Selvam

Few users have observed display corruption when they boot the machine to KDE Plasma or playing games. We have root caused the problem that whenever alloc_range() couldn't find the required memory blocks the function was returning SUCCESS in some of the corner cases. The right approach would be if the total allocated size is less than the required size, the function should return -ENOSPC.

[PATCH] media: mxl5xx: Move xpt structures off stack

by Nathan Chancellor

When building for LoongArch with clang 18.0.0, the stack usage of probe() is larger than the allowed 2048 bytes: drivers/media/dvb-frontends/mxl5xx.c:1698:12: warning: stack frame size (2368) exceeds limit (2048) in 'probe' [-Wframe-larger-than] 1698 | static int probe(struct mxl *state, struct mxl5xx_cfg *cfg) | ^ 1 warning generated. This is the result of the linked LLVM commit, which changes how the arrays of structures in config_ts() get handled with CONFIG_INIT_STACK_ZERO and CONFIG_INIT_STACK_PATTERN, which causes the above warning in combination with inlining, as config_ts() gets inlined into probe(). This warning can be easily fixed by moving the array of structures off of the stackvia 'static const', which is a better location for these variables anyways because they are static data that is only ever read from, never modified, so allocating the stack space is wasteful. This drops the stack usage from 2368 bytes to 256 bytes with the same compiler and configuration.

[PATCH 6.1.y] dlm: Treat dlm_local_addr[0] as sockaddr_storage *

by Jordan Rife

Backport e11dea8 ("dlm: use kernel_connect() and kernel_bind()") to Linux stable 6.1 caused a regression. The original patch expected dlm_local_addrs[0] to be of type sockaddr_storage, because c51c9cd ("fs: dlm: don't put dlm_local_addrs on heap") changed its type from sockaddr_storage* to sockaddr_storage in Linux 6.5+ while in older Linux versions this is still the original sockaddr_storage*.

[PATCH] Bluetooth: qca: fix device-address endianness

by Johan Hovold

The WCN6855 firmware on the Lenovo ThinkPad X13s expects the Bluetooth device address in MSB order when setting it using the EDL_WRITE_BD_ADDR_OPCODE command. Presumably, this is the case for all non-ROME devices which all use the EDL_WRITE_BD_ADDR_OPCODE command for this (unlike the ROME devices which use a different command and expect the address in LSB order). Reverse the little-endian address before setting it to make sure that the address can be configured using tools like btmgmt or using the 'local-bd-address' devicetree property. Note that this can potentially break systems with boot firmware which has started relying on the broken behaviour and is incorrectly passing the address via devicetree in MSB order.

Both the cs_nsec and the wd_nsec value indicate that the readout interval was circa 14.5 seconds. The observed behaviour is that watchdog checks failed for large readout intervals on 8 NUMA node machines. This indicates that the size of the skew was directly proportinal to the length of the readout interval on those machines. The measured clocksource skew, 668 microseconds, was evaluated against a threshold (the md variable) that is suited for readout intervals of roughly WATCHDOG_INTERVAL, i.e. HZ >> 1, which is 0.5 second. The intention of 2e27e793e280 ("clocksource: Reduce clocksource-skew threshold") was to tighten the threshold for evaluating skew and set the lower bound for the uncertainty_margin of clocksources to twice WATCHDOG_MAX_SKEW. Later in c37e85c135ce ("clocksource: Loosen clocksource watchdog constraints"), the WATCHDOG_MAX_SKEW constant was increased to 125 microseconds to fit the limit of NTP, which is able to use a clocksource that suffers from up to 500 microseconds of skew per second. Both the TSC and the HPET use default uncertainty_margin. When the readout interval gets stretched the default uncertainty_margin is no longer a suitable lower bound for evaluating skew - it imposes a limit that is far stricter than the skew with which NTP can deal. The root causes of the skew being directly proportinal to the length of the readout interval are: * the inaccuracy of the shift/mult pairs of clocksources and the watchdog * the conversion to nanoseconds is imprecise for large readout intervals Prevent this by skipping the current watchdog check if the readout interval exceeds 2 * WATCHDOG_INTERVAL. Considering the maximum readout interval of 2 * WATCHDOG_INTERVAL, the current default uncertainty margin (of the TSC and HPET) corresponds to a limit on clocksource skew of 250 ppm (microseconds of skew per second). To keep the limit imposed by NTP (500 microseconds of skew per second) for all possible readout intervals, the margins would have to be scaled so that the threshold value is proportional to the length of the actual readout interval. As for why the readout interval may get stretched: Since the watchdog is executed in softirq context the expiration of the watchdog timer can get severely delayed on account of a ksoftirqd thread not getting to run in a timely manner. Surely, a system with such belated softirq execution is not working well and the scheduling issue should be looked into but the clocksource watchdog should be able to deal with it accordingly.

On a x86_64 arch the same problem doesn't occur.

If MSG_WAITALL is also set and we get a short receive, then we may hit the retry path which decrements sr->len and increments the buffer for a retry.

[PATCH 6.1] f2fs: add helper to check compression level

by Chao Yu

From: Sheng Yong <shengyong(a)oppo.com> commit c571fbb5b59a3741e48014faa92c2f14bc59fe50 upstream. This patch adds a helper function to check if compression level is valid. Meanwhile, this patch fixes a reported issue [1]: The issue is easily reproducible by: 1. dd if=/dev/zero of=test.img count=100 bs=1M 2. mkfs.f2fs -f -O compression,extra_attr ./test.img 3. mount -t f2fs -o compress_algorithm=zstd:6,compress_chksum,atgc,gc_merge,lazytime ./test.img /mnt resulting in [ 60.789982] F2FS-fs (loop0): invalid zstd compress level: 6 A bugzilla report has been submitted in https://bugzilla.kernel.org/show_bug.cgi?id=218471 [1] https://lore.kernel.org/lkml/ZcWDOjKEnPDxZ0Or@google.com/T/ The root cause is commit 00e120b5e4b5 ("f2fs: assign default compression level") tries to check low boundary of compress level w/ zstd_min_clevel(), however, since commit e0c1b49f5b67 ("lib: zstd: Upgrade to latest upstream zstd version 1.4.10"), zstd supports negative compress level, it cast type for negative value returned from zstd_min_clevel() to unsigned int in below check condition, result in repored issue. if (level < zstd_min_clevel() || ...

Yet the driver makes such assumption and releases the TD, allowing the remaining TRBs to be freed or overwritten by new TDs. The xHC should also report completion of the final TRB due to its IOC flag being set by us, regardless of prior errors. This event cannot be recognized if the TD has already been freed earlier, resulting in "Transfer event TRB DMA ptr not part of current TD" error message. Fix this by reusing the logic for processing isoc Transaction Errors. This also handles hosts which fail to report the final completion. Fix transfer length reporting on Babble errors. They may be caused by device malfunction, no guarantee that the buffer has been filled.

[PATCH 1/2] drm/buddy: Fix alloc_range() error handling code

by Arunpravin Paneer Selvam

Few users have observed display corruption when they boot the machine to KDE Plasma or playing games. We have root caused the problem that whenever alloc_range() couldn't find the required memory blocks the function was returning SUCCESS in some of the corner cases. The right approach would be if the total allocated size is less than the required size, the function should return -ENOSPC.

If MSG_WAITALL is also set and we get a short receive, then we may hit the retry path which decrements sr->len and increments the buffer for a retry.

Regression, i.MX7 boot failure, Linux v6.1.77

by Francesco Dolcini

Hello Sasha, kernel v6.1.77 introduces a regression, with a boot failure, on i.MX7, with commit db30f469ae8b ("ARM: dts: imx7s: Fix nand-controller #size-cells"). The issue is known [1][2], changing `#size-cells = <0>` is formally correct, but do not play well with the firmware that are deployed on those embedded devices, leading to a boot failure. A mitigation was implemented in the Linux kernel, commit 84549c816dc3 ("mtd: parsers: ofpart: add workaround for #size-cells 0") that was merged into v6.3, the firmware was also fixed, however existing device using old firmware will not boot anymore if updating to a newer kernel. I would ask you to drop such a patch from any stable patches queue and not backport it to any older kernel. To fix v6.1.y I see two options: - backport 84549c816dc3 - revert db30f469ae8b What do you prefer? Should I send myself a patch?

[PATCH 1/2] HID: wacom: generic: Avoid reporting a serial of '0' to userspace

by Tobita, Tatsunosuke

From: Tatsunosuke Tobita <tatsunosuke.tobita(a)wacom.com> The xf86-input-wacom driver does not treat '0' as a valid serial number and will drop any input report which contains an MSC_SERIAL = 0 event. The kernel driver already takes care to avoid sending any MSC_SERIAL event if the value of serial[0] == 0 (which is the case for devices that don't actually report a serial number), but this is not quite sufficient. Only the lower 32 bits of the serial get reported to userspace, so if this portion of the serial is zero then there can still be problems. This commit allows the driver to report either the lower 32 bits if they are non-zero or the upper 32 bits otherwise.

[PATCH 2/3] irqchip/gic-v3-its: Restore quirk probing for ACPI-based systems

by Marc Zyngier

While refactoring the way the ITSs are probed, the handling of quirks applicable to ACPI-based platforms was lost. As a result, systems such as HIP07 lose their GICv4 functionnality, and some other may even fail to boot, unless they are configured to boot with DT. Move the enabling of quirks into its_probe_one(), making it common to all firmware implementations.

[PATCH 3/3] irqchip/gic-v3-its: Fix GICv4.1 VPE affinity update

by Marc Zyngier

When updating the affinity of a VPE, we currently skip the VMOVP command if the two CPUs are part of the same VPE affinity. But this is wrong, as the doorbell corresponding to this VPE is still delivered on the 'old' CPU, which screws up the balancing. Furthermore, offlining that 'old' CPU results in doorbell interrupts generated for this VPE being discarded. The harsh reality is that we cannot easily elide VMOVP when a set_affinity request occurs. It needs to be obeyed, and if an optimisation is to be made, it is at the point where the affinity change request is made (such as in KVM). Drop the VMOVP elision altogether, and only use the vpe_table_mask to try and stay within the same ITS affinity group if at all possible.

[PATCH 5.10/5.15 v2 0/1 RFC] mm/truncate: fix WARNING in ext4_set_page_dirty()

by Roman Smirnov

Syzkaller reports warning in ext4_set_page_dirty() in 5.10 and 5.15 stable releases. It happens because invalidate_inode_page() frees pages that are needed for the system. To fix this we need to add additional checks to the function. page_mapped() checks if a page exists in the page tables, but this is not enough. The page can be used in other places: https://elixir.bootlin.com/linux/v6.8-rc1/source/include/linux/page_ref.h#L… Kernel outputs an error line related to direct I/O: https://syzkaller.appspot.com/text?tag=CrashLog&x=14ab52dac80000 The problem can be fixed in 5.10 and 5.15 stable releases by the following patch. The patch replaces page_mapped() call with check that finds additional references to the page excluding page cache and filesystem private data. If additional references exist, the page cannot be freed. This version does not include the first patch from the first version. The problem can be fixed without it.

[PATCH] xen/events: close evtchn after mapping cleanup

by Maximilian Heyne

shutdown_pirq and startup_pirq are not taking the irq_mapping_update_lock because they can't due to lock inversion. Both are called with the irq_desc->lock being taking. The lock order, however, is first irq_mapping_update_lock and then irq_desc->lock. This opens multiple races: - shutdown_pirq can be interrupted by a function that allocates an event channel: CPU0 CPU1 shutdown_pirq { xen_evtchn_close(e) __startup_pirq { EVTCHNOP_bind_pirq -> returns just freed evtchn e set_evtchn_to_irq(e, irq) } xen_irq_info_cleanup() { set_evtchn_to_irq(e, -1) } } Assume here event channel e refers here to the same event channel number. After this race the evtchn_to_irq mapping for e is invalid (-1). - __startup_pirq races with __unbind_from_irq in a similar way. Because __startup_pirq doesn't take irq_mapping_update_lock it can grab the evtchn that __unbind_from_irq is currently freeing and cleaning up. In this case even though the event channel is allocated, its mapping can be unset in evtchn_to_irq. The fix is to first cleanup the mappings and then close the event channel. In this way, when an event channel gets allocated it's potential previous evtchn_to_irq mappings are guaranteed to be unset already. This is also the reverse order of the allocation where first the event channel is allocated and then the mappings are setup. On a 5.10 kernel prior to commit 3fcdaf3d7634 ("xen/events: modify internal [un]bind interfaces"), we hit a BUG like the following during probing of NVMe devices. The issue is that during nvme_setup_io_queues, pci_free_irq is called for every device which results in a call to shutdown_pirq. With many nvme devices it's therefore likely to hit this race during boot because there will be multiple calls to shutdown_pirq and startup_pirq are running potentially in parallel. ------------[ cut here ]------------ blkfront: xvda: barrier or flush: disabled; persistent grants: enabled; indirect descriptors: enabled; bounce buffer: enabled kernel BUG at drivers/xen/events/events_base.c:499! invalid opcode: 0000 [#1] SMP PTI CPU: 44 PID: 375 Comm: kworker/u257:23 Not tainted 5.10.201-191.748.amzn2.x86_64 #1 Hardware name: Xen HVM domU, BIOS 4.11.amazon 08/24/2006 Workqueue: nvme-reset-wq nvme_reset_work RIP: 0010:bind_evtchn_to_cpu+0xdf/0xf0 Code: 5d 41 5e c3 cc cc cc cc 44 89 f7 e8 2b 55 ad ff 49 89 c5 48 85 c0 0f 84 64 ff ff ff 4c 8b 68 30 41 83 fe ff 0f 85 60 ff ff ff <0f> 0b 66 66 2e 0f 1f 84 00 00 00 00 00 0f 1f 40 00 0f 1f 44 00 00 RSP: 0000:ffffc9000d533b08 EFLAGS: 00010046 RAX: 0000000000000000 RBX: 0000000000000000 RCX: 0000000000000006 RDX: 0000000000000028 RSI: 00000000ffffffff RDI: 00000000ffffffff RBP: ffff888107419680 R08: 0000000000000000 R09: ffffffff82d72b00 R10: 0000000000000000 R11: 0000000000000000 R12: 00000000000001ed R13: 0000000000000000 R14: 00000000ffffffff R15: 0000000000000002 FS: 0000000000000000(0000) GS:ffff88bc8b500000(0000) knlGS:0000000000000000 CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 CR2: 0000000000000000 CR3: 0000000002610001 CR4: 00000000001706e0 DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000 DR3: 0000000000000000 DR6: 00000000fffe0ff0 DR7: 0000000000000400 Call Trace: ? show_trace_log_lvl+0x1c1/0x2d9 ? show_trace_log_lvl+0x1c1/0x2d9 ? set_affinity_irq+0xdc/0x1c0 ? __die_body.cold+0x8/0xd ? die+0x2b/0x50 ? do_trap+0x90/0x110 ? bind_evtchn_to_cpu+0xdf/0xf0 ? do_error_trap+0x65/0x80 ? bind_evtchn_to_cpu+0xdf/0xf0 ? exc_invalid_op+0x4e/0x70 ? bind_evtchn_to_cpu+0xdf/0xf0 ? asm_exc_invalid_op+0x12/0x20 ? bind_evtchn_to_cpu+0xdf/0xf0 ? bind_evtchn_to_cpu+0xc5/0xf0 set_affinity_irq+0xdc/0x1c0 irq_do_set_affinity+0x1d7/0x1f0 irq_setup_affinity+0xd6/0x1a0 irq_startup+0x8a/0xf0 __setup_irq+0x639/0x6d0 ? nvme_suspend+0x150/0x150 request_threaded_irq+0x10c/0x180 ? nvme_suspend+0x150/0x150 pci_request_irq+0xa8/0xf0 ? __blk_mq_free_request+0x74/0xa0 queue_request_irq+0x6f/0x80 nvme_create_queue+0x1af/0x200 nvme_create_io_queues+0xbd/0xf0 nvme_setup_io_queues+0x246/0x320 ? nvme_irq_check+0x30/0x30 nvme_reset_work+0x1c8/0x400 process_one_work+0x1b0/0x350 worker_thread+0x49/0x310 ? process_one_work+0x350/0x350 kthread+0x11b/0x140 ? __kthread_bind_mask+0x60/0x60 ret_from_fork+0x22/0x30 Modules linked in: ---[ end trace a11715de1eee1873 ]--- Fixes: d46a78b05c0e ("xen: implement pirq type event channels") Cc: stable(a)vger.kernel.org Co-debugged-by: Andrew Panyakin <apanyaki(a)amazon.com> Signed-off-by: Maximilian Heyne <mheyne(a)amazon.de> --- drivers/xen/events/events_base.c | 8 ++++++-- 1 file changed, 6 insertions(+), 2 deletions(-) diff --git a/drivers/xen/events/events_base.c b/drivers/xen/events/events_base.c index b8cfea7812d6..3b9f080109d7 100644 --- a/drivers/xen/events/events_base.c +++ b/drivers/xen/events/events_base.c @@ -923,8 +923,8 @@ static void shutdown_pirq(struct irq_data *data) return; do_mask(info, EVT_MASK_REASON_EXPLICIT); - xen_evtchn_close(evtchn); xen_irq_info_cleanup(info); + xen_evtchn_close(evtchn); } static void enable_pirq(struct irq_data *data) @@ -956,6 +956,7 @@ EXPORT_SYMBOL_GPL(xen_irq_from_gsi); static void __unbind_from_irq(struct irq_info *info, unsigned int irq) { evtchn_port_t evtchn; + bool close_evtchn = false; if (!info) { xen_irq_free_desc(irq); @@ -975,7 +976,7 @@ static void __unbind_from_irq(struct irq_info *info, unsigned int irq) struct xenbus_device *dev; if (!info->is_static) - xen_evtchn_close(evtchn); + close_evtchn = true; switch (info->type) { case IRQT_VIRQ: @@ -995,6 +996,9 @@ static void __unbind_from_irq(struct irq_info *info, unsigned int irq) } xen_irq_info_cleanup(info); + + if (close_evtchn) + xen_evtchn_close(evtchn); } xen_free_irq(info); -- 2.40.1 Amazon Development Center Germany GmbH Krausenstr. 38 10117 Berlin Geschaeftsfuehrung: Christian Schlaeger, Jonathan Weiss Eingetragen am Amtsgericht Charlottenburg unter HRB 149173 B Sitz: Berlin Ust-ID: DE 289 237 879

[tip: irq/urgent] irqchip/irq-brcmstb-l2: Add write memory barrier before exit

The following commit has been merged into the irq/urgent branch of tip: Commit-ID: b0344d6854d25a8b3b901c778b1728885dd99007 Gitweb: https://git.kernel.org/tip/b0344d6854d25a8b3b901c778b1728885dd99007 Author: Doug Berger <opendmb(a)gmail.com> AuthorDate: Fri, 09 Feb 2024 17:24:49 -08:00 Committer: Thomas Gleixner <tglx(a)linutronix.de> CommitterDate: Tue, 13 Feb 2024 09:33:31 +01:00 irqchip/irq-brcmstb-l2: Add write memory barrier before exit It was observed on Broadcom devices that use GIC v3 architecture L1 interrupt controllers as the parent of brcmstb-l2 interrupt controllers that the deactivation of the parent interrupt could happen before the brcmstb-l2 deasserted its output. This would lead the GIC to reactivate the interrupt only to find that no L2 interrupt was pending. The result was a spurious interrupt invoking handle_bad_irq() with its associated messaging. While this did not create a functional problem it is a waste of cycles. The hazard exists because the memory mapped bus writes to the brcmstb-l2 registers are buffered and the GIC v3 architecture uses a very efficient system register write to deactivate the interrupt. Add a write memory barrier prior to invoking chained_irq_exit() to introduce a dsb(st) on those systems to ensure the system register write cannot be executed until the memory mapped writes are visible to the system.

[PATCH] tracing: Fix wasted memory in saved_cmdlines logic

by Steven Rostedt

From: "Steven Rostedt (Google)" <rostedt(a)goodmis.org> While looking at improving the saved_cmdlines cache I found a huge amount of wasted memory that should be used for the cmdlines. The tracing data saves pids during the trace. At sched switch, if a trace occurred, it will save the comm of the task that did the trace. This is saved in a "cache" that maps pids to comms and exposed to user space via the /sys/kernel/tracing/saved_cmdlines file. Currently it only caches by default 128 comms. The structure that uses this creates an array to store the pids using PID_MAX_DEFAULT (which is usually set to 32768). This causes the structure to be of the size of 131104 bytes on 64 bit machines. In hex: 131104 = 0x20020, and since the kernel allocates generic memory in powers of two, the kernel would allocate 0x40000 or 262144 bytes to store this structure. That leaves 131040 bytes of wasted space. Worse, the structure points to an allocated array to store the comm names, which is 16 bytes times the amount of names to save (currently 128), which is 2048 bytes. Instead of allocating a separate array, make the structure end with a variable length string and use the extra space for that. This is similar to a recommendation that Linus had made about eventfs_inode names: https://lore.kernel.org/all/20240130190355.11486-5-torvalds@linux-foundatio… Instead of allocating a separate string array to hold the saved comms, have the structure end with: char saved_cmdlines[]; and round up to the next power of two over sizeof(struct saved_cmdline_buffers) + num_cmdlines * TASK_COMM_LEN It will use this extra space for the saved_cmdline portion. Now, instead of saving only 128 comms by default, by using this wasted space at the end of the structure it can save over 8000 comms and even saves space by removing the need for allocating the other array.

[tip: x86/urgent] x86/mm/ident_map: Use gbpages only where full GB page should be mapped.

by tip-bot2 for Steve Wahl

The following commit has been merged into the x86/urgent branch of tip: Commit-ID: d794734c9bbfe22f86686dc2909c25f5ffe1a572 Gitweb: https://git.kernel.org/tip/d794734c9bbfe22f86686dc2909c25f5ffe1a572 Author: Steve Wahl <steve.wahl(a)hpe.com> AuthorDate: Fri, 26 Jan 2024 10:48:41 -06:00 Committer: Dave Hansen <dave.hansen(a)linux.intel.com> CommitterDate: Mon, 12 Feb 2024 14:53:42 -08:00 x86/mm/ident_map: Use gbpages only where full GB page should be mapped. When ident_pud_init() uses only gbpages to create identity maps, large ranges of addresses not actually requested can be included in the resulting table; a 4K request will map a full GB. On UV systems, this ends up including regions that will cause hardware to halt the system if accessed (these are marked "reserved" by BIOS). Even processor speculation into these regions is enough to trigger the system halt. Only use gbpages when map creation requests include the full GB page of space. Fall back to using smaller 2M pages when only portions of a GB page are included in the request. No attempt is made to coalesce mapping requests. If a request requires a map entry at the 2M (pmd) level, subsequent mapping requests within the same 1G region will also be at the pmd level, even if adjacent or overlapping such requests could have been combined to map a full gbpage. Existing usage starts with larger regions and then adds smaller regions, so this should not have any great consequence.

[PATCH 6.1.y] fs: dlm: don't put dlm_local_addrs on heap

by Jordan Rife

From: Alexander Aring <aahringo(a)redhat.com> commit c51c9cd8addcfbdc097dbefd59f022402183644b upstream This patch removes to allocate the dlm_local_addr[] pointers on the heap. Instead we directly store the type of "struct sockaddr_storage". This removes function deinit_local() because it was freeing memory only. Backport e11dea8 ("dlm: use kernel_connect() and kernel_bind()") to Linux stable 6.1 caused a regression. The original patch expected dlm_local_addrs[0] to be of type sockaddr_storage, because c51c9cd ("fs: dlm: don't put dlm_local_addrs on heap") changed its type from sockaddr_storage* to sockaddr_storage in Linux 6.5+ while in older Linux versions this is still the original sockaddr_storage*.

[PATCH 05/10] arm64: dts: qcom: sc8280xp-x13s: limit pcie4 link speed

by Johan Hovold

Limit the WiFi PCIe link speed to Gen2 speed (500 GB/s), which is the speed that the boot firmware has brought up the link at (and that Windows uses). This is specifically needed to avoid a large amount of link errors when restarting the link during boot (but which are currently not reported). This may potentially also help with intermittent failures to download the ath11k firmware during boot which can be seen when there is a longer delay between restarting the link and loading the WiFi driver (e.g. when using full disk encryption).

[PATCH 0/2] Bluetooth: SCO: possible deadlock in sco_conn_del

by oficerovas＠altlinux.org

From: Alexander Ofitserov <oficerovas(a)altlinux.org> Syzkaller hit 'possible deadlock in sco_conn_del' bug. This bug is not a vulnerability and is reproduced only when running with root privileges for stable 6.1 kernel. This series of patches is fix for this particular bug. Both of these patches were taken from upstream and applied clearly without any conflicts. First one is the fix for the problem and another one is for fix first patch.

[PATCH v3] fs, USB gadget: Remove libaio I/O cancellation support

by Bart Van Assche

Originally io_cancel() only supported cancelling USB reads and writes. If I/O was cancelled successfully, information about the cancelled I/O operation was copied to the data structure the io_cancel() 'result' argument points at. Commit 63b05203af57 ("[PATCH] AIO: retry infrastructure fixes and enhancements") changed the io_cancel() behavior from reporting status information via the 'result' argument into reporting status information on the completion ring. Commit 41003a7bcfed ("aio: remove retry-based AIO") accidentally changed the behavior into not reporting a completion event on the completion ring for cancelled requests. This is a bug because successful cancellation leads to an iocb leak in user space. Since this bug was introduced more than ten years ago and since nobody has complained since then, remove support for I/O cancellation. Keep support for cancellation of IOCB_CMD_POLL requests. Calling kiocb_set_cancel_fn() without knowing whether the caller submitted a struct kiocb or a struct aio_kiocb is unsafe. The following call trace illustrates that without this patch an out-of-bounds write happens if I/O is submitted by io_uring (from a phone with an ARM CPU and kernel 6.1): WARNING: CPU: 3 PID: 368 at fs/aio.c:598 kiocb_set_cancel_fn+0x9c/0xa8 Call trace: kiocb_set_cancel_fn+0x9c/0xa8 ffs_epfile_read_iter+0x144/0x1d0 io_read+0x19c/0x498 io_issue_sqe+0x118/0x27c io_submit_sqes+0x25c/0x5fc __arm64_sys_io_uring_enter+0x104/0xab0 invoke_syscall+0x58/0x11c el0_svc_common+0xb4/0xf4 do_el0_svc+0x2c/0xb0 el0_svc+0x2c/0xa4 el0t_64_sync_handler+0x68/0xb4 el0t_64_sync+0x1a4/0x1a8 Cc: Christoph Hellwig <hch(a)lst.de> Cc: Avi Kivity <avi(a)scylladb.com> Cc: Sandeep Dhavale <dhavale(a)google.com> Cc: Jens Axboe <axboe(a)kernel.dk> Cc: Greg Kroah-Hartman <gregkh(a)linuxfoundation.org> Fixes: 63b05203af57 ("[PATCH] AIO: retry infrastructure fixes and enhancements") Cc: <stable(a)vger.kernel.org> Signed-off-by: Bart Van Assche <bvanassche(a)acm.org> --- drivers/usb/gadget/function/f_fs.c | 25 ------------------- drivers/usb/gadget/legacy/inode.c | 20 --------------- fs/aio.c | 39 +++++------------------------- include/linux/aio.h | 9 ------- 4 files changed, 6 insertions(+), 87 deletions(-) diff --git a/drivers/usb/gadget/function/f_fs.c b/drivers/usb/gadget/function/f_fs.c index 6bff6cb93789..59789292f4f7 100644 --- a/drivers/usb/gadget/function/f_fs.c +++ b/drivers/usb/gadget/function/f_fs.c @@ -1157,25 +1157,6 @@ ffs_epfile_open(struct inode *inode, struct file *file) return stream_open(inode, file); } -static int ffs_aio_cancel(struct kiocb *kiocb) -{ - struct ffs_io_data *io_data = kiocb->private; - struct ffs_epfile *epfile = kiocb->ki_filp->private_data; - unsigned long flags; - int value; - - spin_lock_irqsave(&epfile->ffs->eps_lock, flags); - - if (io_data && io_data->ep && io_data->req) - value = usb_ep_dequeue(io_data->ep, io_data->req); - else - value = -EINVAL; - - spin_unlock_irqrestore(&epfile->ffs->eps_lock, flags); - - return value; -} - static ssize_t ffs_epfile_write_iter(struct kiocb *kiocb, struct iov_iter *from) { struct ffs_io_data io_data, *p = &io_data; @@ -1198,9 +1179,6 @@ static ssize_t ffs_epfile_write_iter(struct kiocb *kiocb, struct iov_iter *from) kiocb->private = p; - if (p->aio) - kiocb_set_cancel_fn(kiocb, ffs_aio_cancel); - res = ffs_epfile_io(kiocb->ki_filp, p); if (res == -EIOCBQUEUED) return res; @@ -1242,9 +1220,6 @@ static ssize_t ffs_epfile_read_iter(struct kiocb *kiocb, struct iov_iter *to) kiocb->private = p; - if (p->aio) - kiocb_set_cancel_fn(kiocb, ffs_aio_cancel); - res = ffs_epfile_io(kiocb->ki_filp, p); if (res == -EIOCBQUEUED) return res; diff --git a/drivers/usb/gadget/legacy/inode.c b/drivers/usb/gadget/legacy/inode.c index 03179b1880fd..99b7366d77af 100644 --- a/drivers/usb/gadget/legacy/inode.c +++ b/drivers/usb/gadget/legacy/inode.c @@ -446,25 +446,6 @@ struct kiocb_priv { unsigned actual; }; -static int ep_aio_cancel(struct kiocb *iocb) -{ - struct kiocb_priv *priv = iocb->private; - struct ep_data *epdata; - int value; - - local_irq_disable(); - epdata = priv->epdata; - // spin_lock(&epdata->dev->lock); - if (likely(epdata && epdata->ep && priv->req)) - value = usb_ep_dequeue (epdata->ep, priv->req); - else - value = -EINVAL; - // spin_unlock(&epdata->dev->lock); - local_irq_enable(); - - return value; -} - static void ep_user_copy_worker(struct work_struct *work) { struct kiocb_priv *priv = container_of(work, struct kiocb_priv, work); @@ -537,7 +518,6 @@ static ssize_t ep_aio(struct kiocb *iocb, iocb->private = priv; priv->iocb = iocb; - kiocb_set_cancel_fn(iocb, ep_aio_cancel); get_ep(epdata); priv->epdata = epdata; priv->actual = 0; diff --git a/fs/aio.c b/fs/aio.c index bb2ff48991f3..c20946d5fcf3 100644 --- a/fs/aio.c +++ b/fs/aio.c @@ -203,7 +203,7 @@ struct aio_kiocb { }; struct kioctx *ki_ctx; - kiocb_cancel_fn *ki_cancel; + int (*ki_cancel)(struct kiocb *); struct io_event ki_res; @@ -587,22 +587,6 @@ static int aio_setup_ring(struct kioctx *ctx, unsigned int nr_events) #define AIO_EVENTS_FIRST_PAGE ((PAGE_SIZE - sizeof(struct aio_ring)) / sizeof(struct io_event)) #define AIO_EVENTS_OFFSET (AIO_EVENTS_PER_PAGE - AIO_EVENTS_FIRST_PAGE) -void kiocb_set_cancel_fn(struct kiocb *iocb, kiocb_cancel_fn *cancel) -{ - struct aio_kiocb *req = container_of(iocb, struct aio_kiocb, rw); - struct kioctx *ctx = req->ki_ctx; - unsigned long flags; - - if (WARN_ON_ONCE(!list_empty(&req->ki_list))) - return; - - spin_lock_irqsave(&ctx->ctx_lock, flags); - list_add_tail(&req->ki_list, &ctx->active_reqs); - req->ki_cancel = cancel; - spin_unlock_irqrestore(&ctx->ctx_lock, flags); -} -EXPORT_SYMBOL(kiocb_set_cancel_fn); - /* * free_ioctx() should be RCU delayed to synchronize against the RCU * protected lookup_ioctx() and also needs process context to call @@ -2158,13 +2142,11 @@ COMPAT_SYSCALL_DEFINE3(io_submit, compat_aio_context_t, ctx_id, #endif /* sys_io_cancel: - * Attempts to cancel an iocb previously passed to io_submit.

[PATCH net 0/7] mptcp: locking cleanup & misc. fixes

by Matthieu Baerts (NGI0)

Patches 1-4 are fixes for issues found by Paolo while working on adding TCP_NOTSENT_LOWAT support. The latter will need to track more states under the msk data lock. Since the locking msk locking schema is already quite complex, do a long awaited clean-up step by moving several confusing lockless initialization under the relevant locks. Note that it is unlikely a real race could happen even prior to such patches as the MPTCP-level state machine implicitly ensures proper serialization of the write accesses, even lacking explicit lock. But still, simplification is welcome and this will help for the maintenance. This can be backported up to v5.6. Patch 5 is a fix for the userspace PM, not to add new local address entries if the address is already in the list. This behaviour can be seen since v5.19. Patch 6 fixes an issue when Fastopen is used. The issue can happen since v6.2. A previous fix has already been applied, but not taking care of all cases according to syzbot. Patch 7 updates Geliang's email address in the MAINTAINERS file.

[PATCH] comedi: comedi_8255: Correct error in subdevice initialization

by Frej Drejhammar

The refactoring done in commit 5c57b1ccecc7 ("comedi: comedi_8255: Rework subdevice initialization functions") to the initialization of the io field of struct subdev_8255_private broke all cards using the drivers/comedi/drivers/comedi_8255.c module. Prior to 5c57b1ccecc7, __subdev_8255_init() initialized the io field in the newly allocated struct subdev_8255_private to the non-NULL callback given to the function, otherwise it used a flag parameter to select between subdev_8255_mmio and subdev_8255_io. The refactoring removed that logic and the flag, as subdev_8255_mm_init() and subdev_8255_io_init() now explicitly pass subdev_8255_mmio and subdev_8255_io respectively to __subdev_8255_init(), only __subdev_8255_init() never sets spriv->io to the supplied callback.

[PATCH] scsi: elx: efct: adjust error handling inside efct_hw_setup_io

by Fedor Pchelkin

IO and WQE buffers are allocated once per HW and can be reused later. If WQE buffers allocation fails then the whole allocation is marked as failed but already created IO array internal objects are not freed. hw->io is freed but not nullified in that specific case - it may become a problem later as efct_hw_setup_io() is supposed to be reusable for the same HW. While at it, use kcalloc instead of kmalloc_array/memset-zero combination and get rid of some needless NULL assignments: nullifying hw->io[i] elements just before freeing hw->io is not really useful.

[PATCH stable 5.4 v2] net: bcmgenet: Fix EEE implementation

[PATCH v2] Revert "usb: typec: tcpm: fix cc role at port reset"

by Badhri Jagan Sridharan

This reverts commit 1e35f074399dece73d5df11847d4a0d7a6f49434. Given that ERROR_RECOVERY calls into PORT_RESET for Hi-Zing the CC pins, setting CC pins to default state during PORT_RESET breaks error recovery. 4.5.2.2.2.1 ErrorRecovery State Requirements The port shall not drive VBUS or VCONN, and shall present a high-impedance to ground (above zOPEN) on its CC1 and CC2 pins. Hi-Zing the CC pins is the inteded behavior for PORT_RESET.

[REGRESSION] 6.7.0: ASoC: SOF: refactoring breaks sof-rt5682 audio on chromebook; successfully bisected

by Mole Shang

I'm relatively new here, first time reporting a regression, so apologies in advance if I'm doing something wrong. I'm using Arch Linux (linux-mainline kernel) on my chromebook Acer Spin 713-2W (Voxel), and after upgrading linux-mainline from 6.7-rc4 to 6.7-rc5 the audio setup isn't working anymore. Firstly I suspected its some changes in the sof- firmware, yet got no luck in upgrading sof-firmware (2023.09.2 -> 2023.12). On certain chromebooks, audio setup needs custom ALSA ucm confs [1], but after contacting the chromebook-linux-audio developer [2], I think it's not a conf problem, but rather a kernel regression. After hours of bisecting, the first bad commit 31ed8da (ASoC: SOF: sof-audio: Modify logic for enabling/disabling topology cores) ensures the regression. demsg log pasted below: // before 31ed8da, working [ 61.572587] sof-audio-pci-intel-tgl 0000:00:1f.3: ipc tx error for 0x60010000 (msg/reply size: 108/20): -22 [ 61.572593] sof-audio-pci-intel-tgl 0000:00:1f.3: HW params ipc failed for stream 1 [ 61.572594] sof-audio-pci-intel-tgl 0000:00:1f.3: ASoC: error at snd_soc_pcm_component_hw_params on 0000:00:1f.3: -22 [ 61.573247] sof-audio-pci-intel-tgl 0000:00:1f.3: ipc tx error for 0x60010000 (msg/reply size: 108/20): -22 [ 61.573250] sof-audio-pci-intel-tgl 0000:00:1f.3: HW params ipc failed for stream 1 [ 61.573251] sof-audio-pci-intel-tgl 0000:00:1f.3: ASoC: error at snd_soc_pcm_component_hw_params on 0000:00:1f.3: -22 [ 61.573888] sof-audio-pci-intel-tgl 0000:00:1f.3: ipc tx error for 0x60010000 (msg/reply size: 108/20): -22 [ 61.573892] sof-audio-pci-intel-tgl 0000:00:1f.3: HW params ipc failed for stream 1 [ 61.573893] sof-audio-pci-intel-tgl 0000:00:1f.3: ASoC: error at snd_soc_pcm_component_hw_params on 0000:00:1f.3: -22 [ 61.574570] sof-audio-pci-intel-tgl 0000:00:1f.3: ipc tx error for 0x60010000 (msg/reply size: 108/20): -22 [ 61.574572] sof-audio-pci-intel-tgl 0000:00:1f.3: HW params ipc failed for stream 1 [ 61.574573] sof-audio-pci-intel-tgl 0000:00:1f.3: ASoC: error at snd_soc_pcm_component_hw_params on 0000:00:1f.3: -22 // after 31ed8da, broken [ 48.930740] sof-audio-pci-intel-tgl 0000:00:1f.3: ipc tx error for 0x30020000 (msg/reply size: 12/0): -13 [ 48.930762] sof-audio-pci-intel-tgl 0000:00:1f.3: failed to free widget DMIC0.IN [ 57.235697] sof-audio-pci-intel-tgl 0000:00:1f.3: ipc tx error for 0x30030000 (msg/reply size: 16/0): -22 [ 57.235701] sof-audio-pci-intel-tgl 0000:00:1f.3: sof_ipc3_route_setup: route DMIC0.IN -> BUF4.0 failed [ 57.235703] sof-audio-pci-intel-tgl 0000:00:1f.3: sof_ipc3_set_up_all_pipelines: route set up failed [ 57.235704] sof-audio-pci-intel-tgl 0000:00:1f.3: Failed to restore pipeline after resume -22 [ 57.235706] sof-audio-pci-intel-tgl 0000:00:1f.3: ASoC: error at snd_soc_pcm_component_pm_runtime_get on 0000:00:1f.3: -22 [ 57.235926] sof-audio-pci-intel-tgl 0000:00:1f.3: ASoC: error at snd_soc_pcm_component_pm_runtime_get on 0000:00:1f.3: -22 [ 57.235966] sof-audio-pci-intel-tgl 0000:00:1f.3: ASoC: error at snd_soc_pcm_component_pm_runtime_get on 0000:00:1f.3: -22 [ 57.236006] sof-audio-pci-intel-tgl 0000:00:1f.3: ASoC: error at snd_soc_pcm_component_pm_runtime_get on 0000:00:1f.3: -22 [ 57.236041] sof-audio-pci-intel-tgl 0000:00:1f.3: ASoC: error at snd_soc_pcm_component_pm_runtime_get on 0000:00:1f.3: -22 [ 57.236074] sof-audio-pci-intel-tgl 0000:00:1f.3: ASoC: error at snd_soc_pcm_component_pm_runtime_get on 0000:00:1f.3: -22 [ 57.236107] sof-audio-pci-intel-tgl 0000:00:1f.3: ASoC: error at snd_soc_pcm_component_pm_runtime_get on 0000:00:1f.3: -22 [ 57.236141] sof-audio-pci-intel-tgl 0000:00:1f.3: ASoC: error at snd_soc_pcm_component_pm_runtime_get on 0000:00:1f.3: -22 [ 57.236173] sof-audio-pci-intel-tgl 0000:00:1f.3: ASoC: error at snd_soc_pcm_component_pm_runtime_get on 0000:00:1f.3: -22 [ 57.236205] sof-audio-pci-intel-tgl 0000:00:1f.3: ASoC: error at snd_soc_pcm_component_pm_runtime_get on 0000:00:1f.3: -22 [ 57.236239] sof-audio-pci-intel-tgl 0000:00:1f.3: ASoC: error at snd_soc_pcm_component_pm_runtime_get on 0000:00:1f.3: -22 Steps to reproduce: - Run chromebook-linux-audio script [2] (this would install custom sof-rt5682 ucm confs [1] into /usr/share/alsa/ucm2/conf.d/sof-rt5682 and write a line `options snd-intel-dspcfg dsp_driver=3` to /etc/modprobe.d/snd-sof.conf) - Reboot, gets audio working on kernels before 31ed8da - Install latest stable kernel (6.7.3), audio broken - Install latest git kernel (6.8-rc2), audio broken - Revert 31ed8da, build upon latest linux-git (6.8-rc2), audio working Apologies for my busyiness that I should have reported it long before the regression enters stable and lts, but sadly linux-lts (6.6.13) seems to be affected too [3].

[PATCH] drm/buddy: Fix alloc_range() error handling code

by Arunpravin Paneer Selvam

Few users have observed display corruption when they boot the machine to KDE Plasma or playing games. We have root caused the problem that whenever alloc_range() couldn't find the required memory blocks the function was returning SUCCESS in some of the corner cases. The right approach would be if the total allocated size is less than the required size, the function should return -ENOSPC.

[PATCH v2] arm64/signal: Don't assume that TIF_SVE means we saved SVE state

by Mark Brown

When we are in a syscall we will only save the FPSIMD subset even though the task still has access to the full register set, and on context switch we will only remove TIF_SVE when loading the register state. This means that the signal handling code should not assume that TIF_SVE means that the register state is stored in SVE format, it should instead check the format that was recorded during save.

Thanks for your report. So we have a 6.1.76 specific regression for the backport of e9cdebbe23f1 ("dlm: use kernel_connect() and kernel_bind()") . Let's loop in the upstream regression list for tracking and people involved for the subsystem to see if the issue can be identified. As it is working for 6.6.15 which includes the commit backport as well it might be very well that a prerequisite is missing. # annotate regression with 6.1.y specific commit #regzbot ^introduced e11dea8f503341507018b60906c4a9e7332f3663 #regzbot link: https://bugs.debian.org/1063338 Any ideas?

[PATCH] drm/buddy: Fix alloc_range() error handling code

by Arunpravin Paneer Selvam

Few users have observed display corruption when they boot the machine to KDE Plasma or playing games. We have root caused the problem that whenever alloc_range() couldn't find the required memory blocks the function was returning SUCCESS in some of the corner cases. The right approach would be if the total allocated size is less than the required size, the function should return -ENOSPC.

[for-linus][PATCH 2/2] tracing: Fix wasted memory in saved_cmdlines logic

by Steven Rostedt

From: "Steven Rostedt (Google)" <rostedt(a)goodmis.org> While looking at improving the saved_cmdlines cache I found a huge amount of wasted memory that should be used for the cmdlines. The tracing data saves pids during the trace. At sched switch, if a trace occurred, it will save the comm of the task that did the trace. This is saved in a "cache" that maps pids to comms and exposed to user space via the /sys/kernel/tracing/saved_cmdlines file. Currently it only caches by default 128 comms. The structure that uses this creates an array to store the pids using PID_MAX_DEFAULT (which is usually set to 32768). This causes the structure to be of the size of 131104 bytes on 64 bit machines. In hex: 131104 = 0x20020, and since the kernel allocates generic memory in powers of two, the kernel would allocate 0x40000 or 262144 bytes to store this structure. That leaves 131040 bytes of wasted space. Worse, the structure points to an allocated array to store the comm names, which is 16 bytes times the amount of names to save (currently 128), which is 2048 bytes. Instead of allocating a separate array, make the structure end with a variable length string and use the extra space for that. This is similar to a recommendation that Linus had made about eventfs_inode names: https://lore.kernel.org/all/20240130190355.11486-5-torvalds@linux-foundatio… Instead of allocating a separate string array to hold the saved comms, have the structure end with: char saved_cmdlines[]; and round up to the next power of two over sizeof(struct saved_cmdline_buffers) + num_cmdlines * TASK_COMM_LEN It will use this extra space for the saved_cmdline portion. Now, instead of saving only 128 comms by default, by using this wasted space at the end of the structure it can save over 8000 comms and even saves space by removing the need for allocating the other array.

[PATCH 1/3] driver core: bus: introduce can_remove()

by Hamza Mahfooz

Currently, drivers have no mechanism to block requests to unbind devices. However, this can cause resource leaks and leave the device in an inconsistent state, such that rebinding the device may cause a hang or otherwise prevent the device from being rebound. So, introduce the can_remove() callback to allow drivers to indicate if it isn't appropriate to remove a device at the given time.

[for-linus][PATCH 1/2] ftrace: Fix DIRECT_CALLS to use SAVE_REGS by default

by Steven Rostedt

From: "Masami Hiramatsu (Google)" <mhiramat(a)kernel.org> The commit 60c8971899f3 ("ftrace: Make DIRECT_CALLS work WITH_ARGS and !WITH_REGS") changed DIRECT_CALLS to use SAVE_ARGS when there are multiple ftrace_ops at the same function, but since the x86 only support to jump to direct_call from ftrace_regs_caller, when we set the function tracer on the same target function on x86, ftrace-direct does not work as below (this actually works on arm64.) At first, insmod ftrace-direct.ko to put a direct_call on 'wake_up_process()'. # insmod kernel/samples/ftrace/ftrace-direct.ko # less trace ... <idle>-0 [006] ..s1. 564.686958: my_direct_func: waking up rcu_preempt-17 <idle>-0 [007] ..s1. 564.687836: my_direct_func: waking up kcompactd0-63 <idle>-0 [006] ..s1. 564.690926: my_direct_func: waking up rcu_preempt-17 <idle>-0 [006] ..s1. 564.696872: my_direct_func: waking up rcu_preempt-17 <idle>-0 [007] ..s1. 565.191982: my_direct_func: waking up kcompactd0-63 Setup a function filter to the 'wake_up_process' too, and enable it. # cd /sys/kernel/tracing/ # echo wake_up_process > set_ftrace_filter # echo function > current_tracer # less trace ... <idle>-0 [006] ..s3. 686.180972: wake_up_process <-call_timer_fn <idle>-0 [006] ..s3. 686.186919: wake_up_process <-call_timer_fn <idle>-0 [002] ..s3. 686.264049: wake_up_process <-call_timer_fn <idle>-0 [002] d.h6. 686.515216: wake_up_process <-kick_pool <idle>-0 [002] d.h6. 686.691386: wake_up_process <-kick_pool Then, only function tracer is shown on x86.

[PATCH v4] mm/zswap: invalidate old entry when store fail or !zswap_enabled

by chengming.zhou＠linux.dev

From: Chengming Zhou <zhouchengming(a)bytedance.com> We may encounter duplicate entry in the zswap_store(): 1. swap slot that freed to per-cpu swap cache, doesn't invalidate the zswap entry, then got reused. This has been fixed. 2. !exclusive load mode, swapin folio will leave its zswap entry on the tree, then swapout again. This has been removed. 3. one folio can be dirtied again after zswap_store(), so need to zswap_store() again. This should be handled correctly. So we must invalidate the old duplicate entry before insert the new one, which actually doesn't have to be done at the beginning of zswap_store(). And this is a normal situation, we shouldn't WARN_ON(1) in this case, so delete it. (The WARN_ON(1) seems want to detect swap entry UAF problem? But not very necessary here.) The good point is that we don't need to lock tree twice in the store success path. Note we still need to invalidate the old duplicate entry in the store failure path, otherwise the new data in swapfile could be overwrite by the old data in zswap pool when lru writeback. We have to do this even when !zswap_enabled since zswap can be disabled anytime. If the folio store success before, then got dirtied again but zswap disabled, we won't invalidate the old duplicate entry in the zswap_store(). So later lru writeback may overwrite the new data in swapfile.

Apply e08ff622c91a to 6.6.y

by Miguel Ojeda

Hi Greg, Sasha, Please consider applying commit e08ff622c91a to 6.6.y. It requires the following chain: 828176d037e2 ("rust: arc: add explicit `drop()` around `Box::from_raw()`") ae6df65dabc3 ("rust: upgrade to Rust 1.72.1") c61bcc278b19 ("rust: task: remove redundant explicit link") a53d8cdd5a0a ("rust: print: use explicit link in documentation") e08ff622c91a ("rust: upgrade to Rust 1.73.0") which applies cleanly to 6.6.y. This upgrades the Rust compiler version from 1.71.1 to 1.73.0 (2 version upgrades + 3 prerequisites for the upgrades), fixing a couple issues with the Rust compiler version currently used in 6.6.y. In particular: - A build error with `CONFIG_RUST_DEBUG_ASSERTIONS` enabled (`.eh_frame` section unexpected generation). This is solved applying up to ae6df65dabc3. - A developer-only Make target error (building `.rsi` single-target files, i.e. the equivalent to requesting a preprocessed file in C). This is solved applying all of them. Thanks! Cheers, Miguel

[PATCH 1/8] docs: kernel_feat.py: fix build error for missing files

by Vegard Nossum

If the directory passed to the '.. kernel-feat::' directive does not exist or the get_feat.pl script does not find any files to extract features from, Sphinx will report the following error: Sphinx parallel build error: UnboundLocalError: local variable 'fname' referenced before assignment make[2]: *** [Documentation/Makefile:102: htmldocs] Error 2 This is due to how I changed the script in c48a7c44a1d0 ("docs: kernel_feat.py: fix potential command injection"). Before that, the filename passed along to self.nestedParse() in this case was weirdly just the whole get_feat.pl invocation.

Commit d5e01266e7f5 ("leds: trigger: netdev: add additional specific link speed mode") in the various changes, reworked the way to set the LINKUP mode in commit cee4bd16c319 ("leds: trigger: netdev: Recheck NETDEV_LED_MODE_LINKUP on dev rename") and moved it to a generic function. This changed the logic where, in the previous implementation the dev from the trigger event was used to check if the carrier was ok, but in the new implementation with the generic function, the dev in trigger_data is used instead. This is problematic and cause a possible kernel panic due to the fact that the dev in the trigger_data still reference the old one as the new one (passed from the trigger event) still has to be hold and saved in the trigger_data struct (done in the NETDEV_REGISTER case). On calling of get_device_state(), an invalid net_dev is used and this cause a kernel panic. To handle this correctly, move the call to get_device_state() after the new net_dev is correctly set in trigger_data (in the NETDEV_REGISTER case) and correctly parse the new dev.

[PATCH] fs: relax mount_setattr() permission checks

by Christian Brauner

When we added mount_setattr() I added additional checks compared to the legacy do_reconfigure_mnt() and do_change_type() helpers used by regular mount(2). If that mount had a parent then verify that the caller and the mount namespace the mount is attached to match and if not make sure that it's an anonymous mount. The real rootfs falls into neither category. It is neither an anoymous mount because it is obviously attached to the initial mount namespace but it also obviously doesn't have a parent mount. So that means legacy mount(2) allows changing mount properties on the real rootfs but mount_setattr(2) blocks this. I never thought much about this but of course someone on this planet of earth changes properties on the real rootfs as can be seen in [1]. Since util-linux finally switched to the new mount api in 2.39 not so long ago it also relies on mount_setattr() and that surfaced this issue when Fedora 39 finally switched to it. Fix this.

[PATCH net] s390/qeth: Fix potential loss of L3-IP@ in case of network issues

by Alexandra Winter

Symptom: In case of a bad cable connection (e.g. dirty optics) a fast sequence of network DOWN-UP-DOWN-UP could happen. UP triggers recovery of the qeth interface. In case of a second DOWN while recovery is still ongoing, it can happen that the IP@ of a Layer3 qeth interface is lost and will not be recovered by the second UP. Problem: When registration of IP addresses with Layer 3 qeth devices fails, (e.g. because of bad address format) the respective IP address is deleted from its hash-table in the driver. If registration fails because of a ENETDOWN condition, the address should stay in the hashtable, so a subsequent recovery can restore it. 3caa4af834df ("qeth: keep ip-address after LAN_OFFLINE failure") fixes this for registration failures during normal operation, but not during recovery. Solution: Keep L3-IP address in case of ENETDOWN in qeth_l3_recover_ip(). For consistency with qeth_l3_add_ip() we also keep it in case of EADDRINUSE, i.e. for some reason the card already/still has this address registered.

[PATCH 0/6] tools: Fix rtla and rv problems (found) with clang

by Daniel Bristot de Oliveira

RHEL people reported some errors when compiling rtla and rv with clang. The command line used to compile the tools is: $ make HOSTCC=clang CC=clang LLVM_IAS=1 The first problem is two unsupported flags passed to the compiler: -ffat-lto-objects and -Wno-maybe-uninitialized. They will be removed if the compile is clang. Also, the clang linker does not automatically recognize the -flto=auto option used at compilation time, so it is explicitly set. With the compiler working, it starts pointing to some warnings and errors about uninitialized variables, variable size, and an unused function. These problems are also fixed.

[PATCH 0/2] ARM: prctl: Reject PR_SET_MDWE where not supported

by Zev Weiss

Hello, I noticed after a recent kernel update that my ARM926 system started segfaulting on any execve() after calling prctl(PR_SET_MDWE). After some investigation it appears that ARMv5 is incapable of providing the appropriate protections for MDWE, since any readable memory is also implicitly executable. (Note that I'm not an expert in either ARM arch details or the mm subsystem, so please bear with me if I've botched something in the above analysis.) The prctl_set_mdwe() function already had some special-case logic added disabling it on PARISC (commit 793838138c15, "prctl: Disable prctl(PR_SET_MDWE) on parisc"); this patch series (1) generalizes that check to use an arch_*() function, and (2) adds a corresponding override for ARM to disable MDWE on pre-ARMv6 CPUs. With the series applied, prctl(PR_SET_MDWE) is rejected on ARMv5 and subsequent execve() calls (as well as mmap(PROT_READ|PROT_WRITE)) can succeed instead of unconditionally failing; on ARMv6 the prctl works as it did previously. Since this was effectively a userspace-breaking change in v6.3 (with newer MDWE-aware userspace on older pre-MDWE kernels the prctl would simply fail safely) I've CCed -stable for v6.3+, though since the patches depend on the PARISC one above it will only apply cleanly on the linux-6.6.y and linux-6.7.y branches, since at least at time of writing the 6.3 through 6.5 branches don't have that patch backported (due to further missing dependencies [0]).

Nilfs2 itself does not use end_buffer_async_write(). But, the async_write flag is now used as a marker by commit 7f42ec394156 ("nilfs2: fix issue with race condition of competition between segments for dirty blocks") as a means of resolving double list insertion of dirty blocks in nilfs_lookup_dirty_data_buffers() and nilfs_lookup_node_buffers() and the resulting crash. This modification is safe as long as it is used for file data and b-tree node blocks where the page caches are independent. However, it was irrelevant and redundant to also introduce async_write for segment summary and super root blocks that share buffers with the backing device. This led to the possibility that the BUG_ON check in end_buffer_async_write would fail as described above, if independent writebacks of the backing device occurred in parallel. The use of async_write for segment summary buffers has already been removed in a previous change. Fix this issue by removing the manipulation of the async_write flag for the remaining super root block buffer.

[merged mm-hotfixes-stable] nilfs2-fix-hang-in-nilfs_lookup_dirty_data_buffers.patch removed from -mm tree

by Andrew Morton

The quilt patch titled Subject: nilfs2: fix hang in nilfs_lookup_dirty_data_buffers() has been removed from the -mm tree. Its filename was nilfs2-fix-hang-in-nilfs_lookup_dirty_data_buffers.patch This patch was dropped because it was merged into the mm-hotfixes-stable branch of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm ------------------------------------------------------ From: Ryusuke Konishi <konishi.ryusuke(a)gmail.com> Subject: nilfs2: fix hang in nilfs_lookup_dirty_data_buffers() Date: Wed, 31 Jan 2024 23:56:57 +0900 Syzbot reported a hang issue in migrate_pages_batch() called by mbind() and nilfs_lookup_dirty_data_buffers() called in the log writer of nilfs2. While migrate_pages_batch() locks a folio and waits for the writeback to complete, the log writer thread that should bring the writeback to completion picks up the folio being written back in nilfs_lookup_dirty_data_buffers() that it calls for subsequent log creation and was trying to lock the folio. Thus causing a deadlock. In the first place, it is unexpected that folios/pages in the middle of writeback will be updated and become dirty. Nilfs2 adds a checksum to verify the validity of the log being written and uses it for recovery at mount, so data changes during writeback are suppressed. Since this is broken, an unclean shutdown could potentially cause recovery to fail. Investigation revealed that the root cause is that the wait for writeback completion in nilfs_page_mkwrite() is conditional, and if the backing device does not require stable writes, data may be modified without waiting. Fix these issues by making nilfs_page_mkwrite() wait for writeback to finish regardless of the stable write requirement of the backing device.

E.g: Taking the following steps: fd = fsopen("hugetlbfs", FSOPEN_CLOEXEC); fsconfig(fd, FSCONFIG_SET_STRING, "pagesize", "1024", 0); fsconfig(fd, FSCONFIG_CMD_CREATE, NULL, NULL, 0); Given that the requested "pagesize" is invalid, ctxt->hstate will be replaced with NULL, losing its previous value, and we will print an error: ... ... case Opt_pagesize: ps = memparse(param->string, &rest); ctx->hstate = h; if (!ctx->hstate) { pr_err("Unsupported page size %lu MB\n", ps / SZ_1M); return -EINVAL; } return 0; ... ... This is a problem because later on, we will dereference ctxt->hstate in hugetlbfs_fill_super() ... ... sb->s_blocksize = huge_page_size(ctx->hstate); ... ... Causing below Oops.

Its filename was nilfs2-fix-data-corruption-in-dsync-block-recovery-for-small-block-sizes.patch This patch was dropped because it was merged into the mm-hotfixes-stable branch of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm ------------------------------------------------------ From: Ryusuke Konishi <konishi.ryusuke(a)gmail.com> Subject: nilfs2: fix data corruption in dsync block recovery for small block sizes Date: Wed, 24 Jan 2024 21:19:36 +0900 The helper function nilfs_recovery_copy_block() of nilfs_recovery_dsync_blocks(), which recovers data from logs created by data sync writes during a mount after an unclean shutdown, incorrectly calculates the on-page offset when copying repair data to the file's page cache.

If NR_CPUS threads call lock_task_sighand() at the same time and the process has NR_THREADS, spin_lock_irq will spin with irqs disabled O(NR_CPUS * NR_THREADS) time. This patch (of 3): thread_group_cputime() does its own locking, we can safely shift thread_group_cputime_adjusted() which does another for_each_thread loop outside of ->siglock protected section. Not only this removes for_each_thread() from the critical section with irqs disabled, this removes another case when stats_lock is taken with siglock held. We want to remove this dependency, then we can change the users of stats_lock to not disable irqs.

[PATCH v2] clocksource: timer-riscv: Clear timer interrupt on timer initialization

[PATCH 5.15 0/1] cifs: Fix stack-out-of-bounds in smb2_set_next_command()

by ZhaoLong Wang

Hello, I am sending this patch for inclusion in the stable tree, as it fixes a critical stack-out-of-bounds bug in the cifs module related to the `smb2_set_next_command()` function. Problem Summary: A problem was observed in the `statfs` system call for cifs, where it failed with a "Resource temporarily unavailable" message. Further investigation with KASAN revealed a stack-out-of-bounds error. The root cause was a miscalculation of the size of the `smb2_query_info_req` structure in the `SMB2_query_info_init()` function. This situation arose due to a dependency on a prior commit (`eb3e28c1e89b`) that replaced a 1-element array with a flexible array member in the `smb2_query_info_req` structure. This commit was not backported to the 5.10.y and 5.15.y stable branch, leading to an incorrect size calculation after the backport of commit `33eae65c6f49`. Fix Details: The patch corrects the size calculation to ensure the correct length is used when initializing the `smb2_query_info_req` structure. It has been tested and confirmed to resolve the issue without introducing any regressions. Maybe the prior commit eb3e28c1e89b ("smb3: Replace smb2pdu 1-element arrays with flex-arrays") should be backported to solve this problem directly. The patch does not seem to conflict. Best regards, ZhaoLong Wang ZhaoLong Wang (1): cifs: Fix stack-out-of-bounds in smb2_set_next_command() fs/cifs/smb2pdu.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) -- 2.39.2

[PATCH v3] mm/zswap: invalidate old entry when store fail or !zswap_enabled

by chengming.zhou＠linux.dev

From: Chengming Zhou <zhouchengming(a)bytedance.com> We may encounter duplicate entry in the zswap_store(): 1. swap slot that freed to per-cpu swap cache, doesn't invalidate the zswap entry, then got reused. This has been fixed. 2. !exclusive load mode, swapin folio will leave its zswap entry on the tree, then swapout again. This has been removed. 3. one folio can be dirtied again after zswap_store(), so need to zswap_store() again. This should be handled correctly. So we must invalidate the old duplicate entry before insert the new one, which actually doesn't have to be done at the beginning of zswap_store(). And this is a normal situation, we shouldn't WARN_ON(1) in this case, so delete it. (The WARN_ON(1) seems want to detect swap entry UAF problem? But not very necessary here.) The good point is that we don't need to lock tree twice in the store success path. Note we still need to invalidate the old duplicate entry in the store failure path, otherwise the new data in swapfile could be overwrite by the old data in zswap pool when lru writeback. We have to do this even when !zswap_enabled since zswap can be disabled anytime.

[PATCH 1/1] netfilter: ipset: Missing gc cancellations fixed

by Jozsef Kadlecsik

The patch fdb8e12cc2cc ("netfilter: ipset: fix performance regression in swap operation") missed to add the calls to gc cancellations at the error path of create operations and at module unload. Also, because the half of the destroy operations now executed by a function registered by call_rcu(), neither NFNL_SUBSYS_IPSET mutex or rcu read lock is held and therefore the checking of them results false warnings.

[PATCH] btrfs: always scan a single device when mounted

by David Sterba

There are reports that since version 6.7 update-grub fails to find the device of the root on systems without initrd and on a single device. This looks like the device name changed in the output of /proc/self/mountinfo: 6.5-rc5 working 18 1 0:16 / / rw,noatime - btrfs /dev/sda8 ... 6.7 not working: 17 1 0:15 / / rw,noatime - btrfs /dev/root ... and "update-grub" shows this error: /usr/sbin/grub-probe: error: cannot find a device for / (is /dev mounted?) This looks like it's related to the device name, but grub-probe recognizes the "/dev/root" path and tries to find the underlying device. However there's a special case for some filesystems, for btrfs in particular. The generic root device detection heuristic is not done and it all relies on reading the device infos by a btrfs specific ioctl. This ioctl returns the device name as it was saved at the time of device scan (in this case it's /dev/root). The change in 6.7 for temp_fsid to allow several single device filesystem to exist with the same fsid (and transparently generate a new UUID at mount time) was to skip caching/registering such devices. This also skipped mounted device. One step of scanning is to check if the device name hasn't changed, and if yes then update the cached value. This broke the grub-probe as it always read the device /dev/root and couldn't find it in the system. A temporary workaround is to create a symlink but this does not survive reboot. The right fix is to allow updating the device path of a mounted filesystem even if this is a single device one. This does not affect the temp_fsid feature, the UUID of the mounted filesystem remains the same and the matching is based on device major:minor which is unique per mounted filesystem. As the main part of device scanning and list update is done in device_list_add() that handles all corner cases and locking, it is extended to take a parameter that tells it to do everything as before, except adding a new device entry. This covers the path when the device (that exists for all mounted devices) name changes, updating /dev/root to /dev/sdx. Any other single device with filesystem is skipped. Note that if a system is booted and initial mount is done on the /dev/root device, this will be the cached name of the device. Only after the command "btrfs device rescan" it will change as it triggers the rename. The fix was verified by users whose systems were affected.

[PATCH v2] mm/zswap: invalidate old entry when store fail or !zswap_enabled

by chengming.zhou＠linux.dev

From: Chengming Zhou <zhouchengming(a)bytedance.com> We may encounter duplicate entry in the zswap_store(): 1. swap slot that freed to per-cpu swap cache, doesn't invalidate the zswap entry, then got reused. This has been fixed. 2. !exclusive load mode, swapin folio will leave its zswap entry on the tree, then swapout again. This has been removed. 3. one folio can be dirtied again after zswap_store(), so need to zswap_store() again. This should be handled correctly. So we must invalidate the old duplicate entry before insert the new one, which actually doesn't have to be done at the beginning of zswap_store(). And this is a normal situation, we shouldn't WARN_ON(1) in this case, so delete it. (The WARN_ON(1) seems want to detect swap entry UAF problem? But not very necessary here.) The good point is that we don't need to lock tree twice in the store success path. Note we still need to invalidate the old duplicate entry in the store failure path, otherwise the new data in swapfile could be overwrite by the old data in zswap pool when lru writeback. We have to do this even when !zswap_enabled since zswap can be disabled anytime. If the folio store success before, then got dirtied again but zswap disabled, we won't invalidate the old duplicate entry in the zswap_store(). So later lru writeback may overwrite the new data in swapfile.

Requesting 3 patches for Apple Magic Keyboard 2021 to be merged to LTS kernels

by Aseda Aboagye

Dear stable kernel maintainers, I am writing to request that 3 related patches be merged to various LTS kernels. I'm not sure if it would have been preferable for me to send 3 separate emails, so please forgive me if I chose wrongly. (This is my first foray into interacting with the kernel community) :) The patches are as follows: 1. 0cd3be51733f (HID: apple: Add support for the 2021 Magic Keyboard, 2021-10-08) 2. 346338ef00d3 (HID: apple: Swap the Fn and Left Control keys on Apple keyboards, 2020-05-15) 3. 531cb56972f2 (HID: apple: Add 2021 magic keyboard FN key mapping, 2021-11-08) These patches have all been merged to mainline, but I believe when they were submitted, backporting may not have been considered. The Apple Magic Keyboard 2021 (Model # A2450) seems to be a popular keyboard, and without these patches, for users on certain LTS kernels that use this keyboard, the function keys do not behave as expected. e.g. Pressing the brightness down or brightness up key didn't work, and bizarrely pressing the globe/Fn key alone caused the brightness to decrease. None of the top row keys worked as expected. I checked to see where the patches were missing and figured that it would be good to have those patches in those kernels. I would ask that patches 1 & 3 be merged to v4.19, v5.4, v5.10, and v5.15. I would ask that patch 2 be merged to: v5.4 and v4.19. For patch 3 to apply cleanly, it needed patch 2 to be present in the tree. Thanks, -- Aseda Aboagye

[PATCH] perf/x86: Fix out of range data

by Namhyung Kim

On x86 each cpu_hw_events maintains a table for counter assignment but it missed to update one for the deleted event in x86_pmu_del(). This can make perf_clear_dirty_counters() reset used counter if it's called before event scheduling or enabling. Then it would return out of range data which doesn't make sense. The following code can reproduce the problem. $ cat repro.c #include <pthread.h> #include <stdio.h> #include <stdlib.h> #include <unistd.h> #include <linux/perf_event.h> #include <sys/ioctl.h> #include <sys/mman.h> #include <sys/syscall.h> struct perf_event_attr attr = { .type = PERF_TYPE_HARDWARE, .config = PERF_COUNT_HW_CPU_CYCLES, .disabled = 1, }; void *worker(void *arg) { int cpu = (long)arg; int fd1 = syscall(SYS_perf_event_open, &attr, -1, cpu, -1, 0); int fd2 = syscall(SYS_perf_event_open, &attr, -1, cpu, -1, 0); void *p; do { ioctl(fd1, PERF_EVENT_IOC_ENABLE, 0); p = mmap(NULL, 4096, PROT_READ, MAP_SHARED, fd1, 0); ioctl(fd2, PERF_EVENT_IOC_ENABLE, 0); ioctl(fd2, PERF_EVENT_IOC_DISABLE, 0); munmap(p, 4096); ioctl(fd1, PERF_EVENT_IOC_DISABLE, 0); } while (1); return NULL; } int main(void) { int i; int n = sysconf(_SC_NPROCESSORS_ONLN); pthread_t *th = calloc(n, sizeof(*th)); for (i = 0; i < n; i++) pthread_create(&th[i], NULL, worker, (void *)(long)i); for (i = 0; i < n; i++) pthread_join(th[i], NULL); free(th); return 0; } And you can see the out of range data using perf stat like this. Probably it'd be easier to see on a large machine. $ gcc -o repro repro.c -pthread $ ./repro & $ sudo perf stat -A -I 1000 2>&1 | awk '{ if (length($3) > 15) print }' 1.001028462 CPU6 196,719,295,683,763 cycles # 194290.996 GHz (71.54%) 1.001028462 CPU3 396,077,485,787,730 branch-misses # 15804359784.80% of all branches (71.07%) 1.001028462 CPU17 197,608,350,727,877 branch-misses # 14594186554.56% of all branches (71.22%) 2.020064073 CPU4 198,372,472,612,140 cycles # 194681.113 GHz (70.95%) 2.020064073 CPU6 199,419,277,896,696 cycles # 195720.007 GHz (70.57%) 2.020064073 CPU20 198,147,174,025,639 cycles # 194474.654 GHz (71.03%) 2.020064073 CPU20 198,421,240,580,145 stalled-cycles-frontend # 100.14% frontend cycles idle (70.93%) 3.037443155 CPU4 197,382,689,923,416 cycles # 194043.065 GHz (71.30%) 3.037443155 CPU20 196,324,797,879,414 cycles # 193003.773 GHz (71.69%) 3.037443155 CPU5 197,679,956,608,205 stalled-cycles-backend # 1315606428.66% backend cycles idle (71.19%) 3.037443155 CPU5 198,571,860,474,851 instructions # 13215422.58 insn per cycle It should move the contents in the cpuc->assign as well.

[PATCH v3 8/8] m68k: Move signal frame following exception on 68020/030

by Michael Schmitz

From: Finn Thain <fthain(a)linux-m68k.org> commit b845b574f86dcb6a70dfa698aa87a237b0878d2a upstream. On 68030/020, an instruction such as, moveml %a2-%a3/%a5,%sp@- may cause a stack page fault during instruction execution (i.e. not at an instruction boundary) and produce a format 0xB exception frame. In this situation, the value of USP will be unreliable. If a signal is to be delivered following the exception, this USP value is used to calculate the location for a signal frame. This can result in a corrupted user stack. The corruption was detected in dash (actually in glibc) where it showed up as an intermittent "stack smashing detected" message and crash following signal delivery for SIGCHLD. It was hard to reproduce that failure because delivery of the signal raced with the page fault and because the kernel places an unpredictable gap of up to 7 bytes between the USP and the signal frame. A format 0xB exception frame can be produced by a bus error or an address error. The 68030 Users Manual says that address errors occur immediately upon detection during instruction prefetch. The instruction pipeline allows prefetch to overlap with other instructions, which means an address error can arise during the execution of a different instruction. So it seems likely that this patch may help in the address error case also.

[PATCH v3 1/8] m68k/mm: Adjust VM area to be unmapped by gap size for __iounmap()

by Michael Schmitz

commit 3f90f9ef2dda316d64e420d5d51ba369587ccc55 upstream. If 020/030 support is enabled, get_io_area() leaves an IO_SIZE gap between mappings which is added to the vm_struct representing the mapping. __ioremap() uses the actual requested size (after alignment), while __iounmap() is passed the size from the vm_struct. On 020/030, early termination descriptors are used to set up mappings of extent 'size', which are validated on unmapping. The unmapped gap of size IO_SIZE defeats the sanity check of the pmd tables, causing __iounmap() to loop forever on 030. On 040/060, unmapping of page table entries does not check for a valid mapping, so the umapping loop always completes there. Adjust size to be unmapped by the gap that had been added in the vm_struct prior. This fixes the hang in atari_platform_init() reported a long time ago, and a similar one reported by Finn recently (addressed by removing ioremap() use from the SWIM driver. Tested on my Falcon in 030 mode - untested but should work the same on 040/060 (the extra page tables cleared there would never have been set up anyway).

[PATCH] blk-wbt: Fix detection of dirty-throttled tasks

by Jan Kara

The detection of dirty-throttled tasks in blk-wbt has been subtly broken since its beginning in 2016. Namely if we are doing cgroup writeback and the throttled task is not in the root cgroup, balance_dirty_pages() will set dirty_sleep for the non-root bdi_writeback structure. However blk-wbt checks dirty_sleep only in the root cgroup bdi_writeback structure. Thus detection of recently throttled tasks is not working in this case (we noticed this when we switched to cgroup v2 and suddently writeback was slow). Since blk-wbt has no easy way to get to proper bdi_writeback and furthermore its intention has always been to work on the whole device rather than on individual cgroups, just move the dirty_sleep timestamp from bdi_writeback to backing_dev_info. That fixes the checking for recently throttled task and saves memory for everybody as a bonus.

[PATCH v6 0/4] Regather scattered PCI-Code

by Philipp Stanner

@Stable-Kernel: You receive this patch series because its first patch fixes a leak in PCI. @Bjorn: I decided that it's now actually possible to just embed the docu updates to the respective patches, instead of a separate patch. Also dropped the ioport_unmap() for now. Changes in v6: - Remove the addition of ioport_unmap() from patch #1, since this is not really a bug, as explained by the comment above pci_iounmap. (Bjorn) - Drop the patch unifying the two versions of pci_iounmap(). (Bjorn) - Make patch #4's style congruent with PCI style. - Drop (in any case empty) ioport_unmap() again from pci_iounmap() - Add forgotten updates to Documentation/ when moving files from lib/ to drivers/pci/ Changes in v5: - Add forgotten update to MAINTAINERS file. Changes in v4: - Apply Arnd's Reviewed-by's - Add ifdef CONFIG_HAS_IOPORT_MAP guard in drivers/pci/iomap.c (build error on openrisc) - Fix typo in patch no.5 Changes in v3: - Create a separate patch for the leaks in lib/iomap.c. Make it the series' first patch. (Arnd) - Turns out the aforementioned bug wasn't just accidentally removing iounmap() with the ifdef, it was also missing ioport_unmap() to begin with. Add it. - Move the ARCH_WANTS_GENERIC_IOMEM_IS_IOPORT-mechanism from asm-generic/io.h to asm-generic/ioport.h. (Arnd) - Adjust the implementation of iomem_is_ioport() in asm-generic/io.h so that it matches exactly what pci_iounmap() previously did in lib/pci_iomap.c. (Arnd) - Move the CONFIG_HAS_IOPORT guard in asm-generic/io.h so that iomem_is_ioport() will always be compiled and just returns false if there are no ports. - Add TODOs to several places informing about the generic iomem_is_ioport() in lib/iomap.c not being generic. - Add TODO about the followup work to make drivers/pci/iomap.c's pci_iounmap() actually generic. Changes in v2: - Replace patch 4, previously extending the comment about pci_iounmap() in lib/iomap.c, with a patch that moves pci_iounmap() from that file to drivers/pci/iomap.c, creating a unified version there. (Arnd) - Implement iomem_is_ioport() as a new helper in asm-generic/io.h and lib/iomap.c. (Arnd) - Move the build rule in drivers/pci/Makefile for iomap.o under the guard of #if PCI. This had to be done because when just checking for GENERIC_PCI_IOMAP being defined, the functions don't disappear, which was the case previously in lib/pci_iomap.c, where the entire file was made empty if PCI was not set by the guard #ifdef PCI. (Intel's Bots) - Rephares all patches' commit messages a little bit. Sooooooooo. I reworked v1. Please review this carefully, the IO-Ranges are obviously a bit tricky, as is the build-system / ifdef-ery. Arnd has suggested that architectures defining a custom inb() need their own iomem_is_ioport(), as well. I've grepped for inb() and found the following list of archs that define their own: - alpha - arm - m68k <-- - parisc - powerpc - sh - sparc - x86 <-- All of those have their own definitons of pci_iounmap(). Therefore, they don't need our generic version in the first place and, thus, also need no iomem_is_ioport(). The two exceptions are x86 and m68k. The former uses lib/iomap.c through CONFIG_GENERIC_IOMAP, as Arnd pointed out in the previous discussion (thus, CONFIG_GENERIC_IOMAP is not really generic in this regard). So as I see it, only m68k WOULD need its own custom definition of iomem_is_ioport(). But as I understand it it doesn't because it uses the one from asm-generic/pci_iomap.h ?? I wasn't entirely sure how to deal with the address ranges for the generic implementation in asm-generic/io.h. It's marked with a TODO. Input appreciated. I removed the guard around define pci_iounmap in asm-generic/io.h. An alternative would be to have it be guarded by CONFIG_GENERIC_IOMAP and CONFIG_GENERIC_PCI_IOMAP, both. Without such a guard, there is no collision however, because generic pci_iounmap() from drivers/pci/iomap.c will only get pulled in when CONFIG_GENERIC_PCI_IOMAP is actually set. I cross-built this for a variety of architectures, including the usual suspects (s390, m68k). So far successfully. But let's see what Intel's robots say :O P. Original cover letter: Hi! So it seems that since ca. 2007 the PCI code has been scattered a bit. PCI's devres code, which is only ever used by users of the entire PCI-subsystem anyways, resides in lib/devres.c and is guarded by an ifdef PCI, just as the content of lib/pci_iomap.c is. It, thus, seems reasonable to move all of that. As I were at it, I moved as much of the devres-specific code from pci.c to devres.c, too. The only exceptions are four functions that are currently difficult to move. More information about that can be read here [1]. I noticed these scattered files while working on (new) PCI-specific devres functions. If we can get this here merged, I'll soon send another patch series that addresses some API-inconsistencies and could move the devres-part of the four remaining functions. I don't want to do that in this series as this here is only about moving code, whereas the next series would have to actually change API behavior. I successfully (cross-)built this for x86, x86_64, AARCH64 and ARM (allyesconfig). I booted a kernel with it on x86_64, with a Fedora desktop environment as payload. The OS came up fine I hope this is OK. If we can get it in, we'd soon have a very consistent PCI API again. Regards, P.

[PATCH] HID: wacom: Do not register input devices until after hid_hw_start

by Gerecke, Jason

From: Jason Gerecke <killertofu(a)gmail.com> If a input device is opened before hid_hw_start is called, events may not be received from the hardware. In the case of USB-backed devices, for example, the hid_hw_start function is responsible for filling in the URB which is submitted when the input device is opened. If a device is opened prematurely, polling will never start because the device will not have been in the correct state to send the URB. Because the wacom driver registers its input devices before calling hid_hw_start, there is a window of time where a device can be opened and end up in an inoperable state. Some ARM-based Chromebooks in particular reliably trigger this bug. This commit splits the wacom_register_inputs function into two pieces. One which is responsible for setting up the allocated inputs (and runs prior to hid_hw_start so that devices are ready for any input events they may end up receiving) and another which only registers the devices (and runs after hid_hw_start to ensure devices can be immediately opened without issue). Note that the functions to initialize the LEDs and remotes are also moved after hid_hw_start to maintain their own dependency chains.

Without the sanitizers enabled, there are no warnings. This was the catalyst for commit 6740ec97bcdb ("drm/amd/display: Increase frame warning limit with KASAN or KCSAN in dml2") and that same change was made to dml in commit 5b750b22530f ("drm/amd/display: Increase frame warning limit with KASAN or KCSAN in dml") but the frame_warn_flag variable was not applied to all files. Do so now to clear up the warnings and make all these files consistent.

[tip: timers/urgent] hrtimer: Report offline hrtimer enqueue

The following commit has been merged into the timers/urgent branch of tip: Commit-ID: dad6a09f3148257ac1773cd90934d721d68ab595 Gitweb: https://git.kernel.org/tip/dad6a09f3148257ac1773cd90934d721d68ab595 Author: Frederic Weisbecker <frederic(a)kernel.org> AuthorDate: Mon, 29 Jan 2024 15:56:36 -08:00 Committer: Thomas Gleixner <tglx(a)linutronix.de> CommitterDate: Tue, 06 Feb 2024 10:56:35 +01:00 hrtimer: Report offline hrtimer enqueue The hrtimers migration on CPU-down hotplug process has been moved earlier, before the CPU actually goes to die. This leaves a small window of opportunity to queue an hrtimer in a blind spot, leaving it ignored. For example a practical case has been reported with RCU waking up a SCHED_FIFO task right before the CPUHP_AP_IDLE_DEAD stage, queuing that way a sched/rt timer to the local offline CPU. Make sure such situations never go unnoticed and warn when that happens. Fixes: 5c0930ccaad5 ("hrtimers: Push pending hrtimers away from outgoing CPU earlier") Reported-by: Paul E.

[PATCH net] s390/qeth: Fix potential loss of L3-IP@ in case of network issues

by Alexandra Winter

Symptom: In case of a bad cable connection (e.g. dirty optics) a fast sequence of network DOWN-UP-DOWN-UP could happen. UP triggers recovery of the qeth interface. In case of a second DOWN while recovery is still ongoing, it can happen that the IP@ of a Layer3 qeth interface is lost and will not be recovered by the second UP. Problem: When registration of IP addresses with Layer 3 qeth devices fails, (e.g. because of bad address format) the respective IP address is deleted from its hash-table in the driver. If registration fails because of a ENETDOWN condition, the address should stay in the hashtable, so a subsequent recovery can restore it. 3caa4af834df ("qeth: keep ip-address after LAN_OFFLINE failure") fixes this for registration failures during normal operation, but not during recovery. Solution: Keep L3-IP address in case of ENETDOWN in qeth_l3_recover_ip(). For consistency with qeth_l3_add_ip() we also keep it in case of EADDRINUSE, i.e. for some reason the card already/still has this address registered.

However, the following schemes applying function, damon_do_apply_schemes() iterates all schemes without the apply interval check. As a result, the shortest apply interval is applied to all schemes. Fix the problem by checking the apply interval in damon_do_apply_schemes().

[PATCH RESEND] mm/damon/core: check apply interval in damon_do_apply_schemes()

by SeongJae Park

kdamond_apply_schemes() checks apply intervals of schemes and avoid further applying any schemes if no scheme passed its apply interval. However, the following schemes applying function, damon_do_apply_schemes() iterates all schemes without the apply interval check. As a result, the shortest apply interval is applied to all schemes.

[PATCH net 0/3] nfp: a few simple driver fixes

by Louis Peens

This is combining a few unrelated one-liner fixes which have been floating around internally into a single series. I'm not sure what is the least amount of overhead for reviewers, this or a separate submission per-patch? I guess it probably depends on personal preference, but please let me know if there is a strong preference to rather split these in the future. Summary: Patch1: Fixes an old issue which was hidden because 0 just so happens to be the correct value. Patch2: Fixes a corner case for flower offloading with bond ports Patch3: Re-enables the 'NETDEV_XDP_ACT_REDIRECT', which was accidentally disabled after a previous refactor. Daniel Basilio (1): nfp: use correct macro for LengthSelect in BAR config Daniel de Villiers (1): nfp: flower: prevent re-adding mac index for bonded port James Hershaw (1): nfp: enable NETDEV_XDP_ACT_REDIRECT feature flag drivers/net/ethernet/netronome/nfp/flower/tunnel_conf.c | 2 +- drivers/net/ethernet/netronome/nfp/nfp_net_common.c | 1 + drivers/net/ethernet/netronome/nfp/nfpcore/nfp6000_pcie.c | 6 ++++-- 3 files changed, 6 insertions(+), 3 deletions(-) -- 2.34.1

[PATCH] ASoC: tas2781: add module parameter to tascodec_init()

by Gergo Koteles

The tascodec_init() of the snd-soc-tas2781-comlib module is called from snd-soc-tas2781-i2c and snd-hda-scodec-tas2781-i2c modules. It calls request_firmware_nowait() with parameter THIS_MODULE and a cont/callback from the latter modules. The latter modules can be removed while their callbacks are running, resulting in a general protection failure. Add module parameter to tascodec_init() so request_firmware_nowait() can be called with the module of the callback.

[PATCH v2] mtd: rawnand: marvell: fix layouts

by Elad Nachman

From: Elad Nachman <enachman(a)marvell.com> The check in nand_base.c, nand_scan_tail() : has the following code: (ecc->steps * ecc->size != mtd->writesize) which fails for some NAND chips. Remove ECC entries in this driver which are not integral multiplications, and adjust the number of chunks for entries which fails the above calculation so it will calculate correctly (this was previously done automatically before the check and was removed in a later commit).

[git:media_stage/master] media: nxp: imx8-isi: Mark all crossbar sink pads as MUST_CONNECT

by Hans Verkuil

[git:media_stage/master] media: mc: Add local pad to pipeline regardless of the link state

by Hans Verkuil

This is an automatic generated email to let you know that the following patch were queued: Subject: media: mc: Add local pad to pipeline regardless of the link state Author: Laurent Pinchart <laurent.pinchart(a)ideasonboard.com> Date: Sun Jan 14 15:55:40 2024 +0200 When building pipelines by following links, the media_pipeline_explore_next_link() function only traverses enabled links. The remote pad of a disabled link is not added to the pipeline, and neither is the local pad. While the former is correct as disabled links should not be followed, not adding the local pad breaks processing of the MEDIA_PAD_FL_MUST_CONNECT flag. The MEDIA_PAD_FL_MUST_CONNECT flag is checked in the __media_pipeline_start() function that iterates over all pads after populating the pipeline. If the pad is not present, the check gets skipped, rendering it useless. Fix this by adding the local pad of all links regardless of their state, only skipping the remote pad for disabled links.

[git:media_stage/master] media: mc: Fix flags handling when creating pad links

by Hans Verkuil

This is an automatic generated email to let you know that the following patch were queued: Subject: media: mc: Fix flags handling when creating pad links Author: Laurent Pinchart <laurent.pinchart(a)ideasonboard.com> Date: Mon Jan 15 00:24:12 2024 +0200 The media_create_pad_link() function doesn't correctly clear reject link type flags, nor does it set the DATA_LINK flag. It only works because the MEDIA_LNK_FL_DATA_LINK flag's value is 0. Fix it by returning an error if any link type flag is set. This doesn't introduce any regression, as nobody calls the media_create_pad_link() function with link type flags (easily checked by grepping for the flag in the source code, there are very few hits). Set the MEDIA_LNK_FL_DATA_LINK explicitly, which is a no-op that the compiler will optimize out, but is still useful to make the code more explicit and easier to understand.

[git:media_stage/master] media: nxp: imx8-isi: Check whether crossbar pad is non-NULL before access

This is an automatic generated email to let you know that the following patch were queued: Subject: media: nxp: imx8-isi: Check whether crossbar pad is non-NULL before access Author: Marek Vasut <marex(a)denx.de> Date: Fri Dec 1 16:06:04 2023 +0100 When translating source to sink streams in the crossbar subdev, the driver tries to locate the remote subdev connected to the sink pad. The remote pad may be NULL, if userspace tries to enable a stream that ends at an unconnected crossbar sink. When that occurs, the driver dereferences the NULL pad, leading to a crash.

[git:media_stage/master] media: mc: Expand MUST_CONNECT flag to always require an enabled link

by Hans Verkuil

This is an automatic generated email to let you know that the following patch were queued: Subject: media: mc: Expand MUST_CONNECT flag to always require an enabled link Author: Laurent Pinchart <laurent.pinchart(a)ideasonboard.com> Date: Mon Jan 15 01:04:52 2024 +0200 The MEDIA_PAD_FL_MUST_CONNECT flag indicates that the pad requires an enabled link to stream, but only if it has any link at all. This makes little sense, as if a pad is part of a pipeline, there are very few use cases for an active link to be mandatory only if links exist at all. A review of in-tree drivers confirms they all need an enabled link for pads marked with the MEDIA_PAD_FL_MUST_CONNECT flag. Expand the scope of the flag by rejecting pads that have no links at all. This requires modifying the pipeline build code to add those pads to the pipeline.

[v6.7][PATCH 00/23] eventfs: Linus's updates for 6.7

by Steven Rostedt

This is a backport of all the work that lead up to the work that Linus made on eventfs. I trust Linus's version more so than the versions in 6.6 and 6.7. There may be plenty of hidden issues due to the design. This is the update for 6.7. It includes Linus's updates as well as all the patches leading up to them. I ran these through my full test suite that I use before sending anyting to Linus, althouh I did not run my "bisect" test that walks through the patches. The tests were just run on the end result. I'm currently running my 6.6 version through my tests. Erick Archer (1): eventfs: Use kcalloc() instead of kzalloc() Linus Torvalds (7): tracefs: remove stale 'update_gid' code eventfs: Initialize the tracefs inode properly tracefs: Avoid using the ei->dentry pointer unnecessarily tracefs: dentry lookup crapectomy eventfs: Remove unused d_parent pointer field eventfs: Clean up dentry ops and add revalidate function eventfs: Get rid of dentry pointers without refcounts Steven Rostedt (Google) (15): eventfs: Remove "lookup" parameter from create_dir/file_dentry() eventfs: Stop using dcache_readdir() for getdents() tracefs/eventfs: Use root and instance inodes as default ownership eventfs: Have eventfs_iterate() stop immediately if ei->is_freed is set eventfs: Do ctx->pos update for all iterations in eventfs_iterate() eventfs: Read ei->entries before ei->children in eventfs_iterate() eventfs: Shortcut eventfs_iterate() by skipping entries already read eventfs: Have the inodes all for files and directories all be the same eventfs: Do not create dentries nor inodes in iterate_shared eventfs: Save directory inodes in the eventfs_inode structure tracefs: Zero out the tracefs_inode when allocating it eventfs: Warn if an eventfs_inode is freed without is_freed being set eventfs: Restructure eventfs_inode structure to be more condensed eventfs: Remove fsnotify*() functions from lookup() eventfs: Keep all directory links at 1 ---- fs/tracefs/event_inode.c | 905 ++++++++++++++++------------------------------- fs/tracefs/inode.c | 286 +++++++-------- fs/tracefs/internal.h | 48 ++- 3 files changed, 451 insertions(+), 788 deletions(-)

[PATCH v2] mtd: rawnand: marvell: fix layouts

by Elad Nachman

From: Elad Nachman <enachman(a)marvell.com> The check in nand_base.c, nand_scan_tail() : has the following code: (ecc->steps * ecc->size != mtd->writesize) which fails for some NAND chips. Remove ECC entries in this driver which are not integral multiplications, and adjust the number of chunks for entries which fails the above calculation so it will calculate correctly (this was previously done automatically before the check and was removed in a later commit).

[git:media_stage/master] media: xc4000: Fix atomicity violation in xc4000_get_frequency

by Hans Verkuil

This is an automatic generated email to let you know that the following patch were queued: Subject: media: xc4000: Fix atomicity violation in xc4000_get_frequency Author: Gui-Dong Han <2045gemini(a)gmail.com> Date: Fri Dec 22 13:50:30 2023 +0800 In xc4000_get_frequency(): *freq = priv->freq_hz + priv->freq_offset; The code accesses priv->freq_hz and priv->freq_offset without holding any lock. In xc4000_set_params(): // Code that updates priv->freq_hz and priv->freq_offset ... xc4000_get_frequency() and xc4000_set_params() may execute concurrently, risking inconsistent reads of priv->freq_hz and priv->freq_offset. Since these related data may update during reading, it can result in incorrect frequency calculation, leading to atomicity violations. This possible bug is found by an experimental static analysis tool developed by our team, BassCheck[1]. This tool analyzes the locking APIs to extract function pairs that can be concurrently executed, and then analyzes the instructions in the paired functions to identify possible concurrency bugs including data races and atomicity violations. The above possible bug is reported when our tool analyzes the source code of Linux 6.2. To address this issue, it is proposed to add a mutex lock pair in xc4000_get_frequency() to ensure atomicity. With this patch applied, our tool no longer reports the possible bug, with the kernel configuration allyesconfig for x86_64. Due to the lack of associated hardware, we cannot test the patch in runtime testing, and just verify it according to the code logic.

[PATCH] ARM: ep93xx: Add terminator to gpiod_lookup_table
