The agilent_82357a driver uses the USB device serial string for device
matching but does not verify that the string exists before passing it
to strcmp().
Verify that the device has a serial number before accessing it to avoid
triggering a NULL-pointer dereference with devices that don't provide
a serial number (iSerialNumber = 0).
Similar to commit aa79f996eb ("i2c: cp2615: fix serial string
NULL-deref at probe").

The applicom driver supports PCI Profibus cards from Applicom, later
acquired by Molex. It has severe coding style issues and has attracted
a number of bug and security fixes over the years, despite the fact
that no one appears to be using it. It was broken from at least the
beginning of Git history (Linux 2.6.12-rc2 in April 2005) until October
2008, when a fatal bug was fixed in commit bc20589bf1 ("applicom.c:
fix apparently-broken code in do_ac_read()"). In the commit message,
the author commented that no one they knew was able to test the change.
Since then, there have been no commits that indicate the driver is
being used. Later PCI and PCI-Express Applicom Profibus cards only
officially support Windows [1], and even the PCI-Express cards have
been discontinued [2]. Given all these factors, remove the driver to
reduce future maintenance workload.

The dtlk driver supports the RC Systems DoubleTalk PC ISA speech
synthesizer card. It has severe coding style issues and has only
received tree-wide fixes and drive-by cleanups in the entire Git
history (since Linux 2.6.12-rc2). The same hardware is supported by
drivers/accessibility/speakup for screen reader use, but that
implementation does not share any code with this driver. Given all of
these factors, it is likely the driver is entirely unused. Remove it to
reduce future maintenance workload.

acrn_irqfd_deassign() and the eventfd EPOLLHUP wakeup can race and free
the same struct hsm_irqfd:
CPU0 CPU1
---- ----
eventfd_release()
wake_up_poll(EPOLLHUP)
hsm_irqfd_wakeup()
queue_work(&irqfd->shutdown)
acrn_irqfd_deassign()
hsm_irqfd_shutdown()
list_del_init()
eventfd_ctx_remove_wait_queue()
eventfd_ctx_put()
kfree(irqfd)
hsm_irqfd_shutdown_work()
container_of(work, ..., shutdown)
irqfd->vm <-- use-after-free
The deassign path freed the irqfd while a shutdown work item was
already queued by EPOLLHUP (or vice versa), so the work item could
resurrect a dangling pointer through container_of().
Switch to the lifetime model used by KVM irqfds:
- Deassign/deinit only deactivate the irqfd: remove it from vm->irqfds
under irqfds_lock and queue the cleanup work.
- hsm_irqfd_shutdown_work() becomes the sole owner that unhooks the
eventfd waitqueue entry, drops the eventfd reference and frees the
irqfd.
- A new HSM_IRQFD_FLAG_SHUTDOWN bit guarded by test_and_set_bit()
ensures the cleanup work is queued at most once, no matter how many
of {EPOLLHUP, deassign, deinit} fire concurrently. This is safe to
call from the waitqueue callback, which runs with wqh->lock held and
IRQs disabled and therefore cannot take irqfds_lock.
- acrn_irqfd_deassign() flushes vm->irqfd_wq before returning so the
eventfd is fully detached on return. acrn_irqfd_deinit() deactivates
every irqfd, flushes the workqueue and only then destroys it, so no
path can queue_work() onto a torn-down workqueue.
- acrn_irqfd_assign() now installs the eventfd waitqueue entry and
publishes the irqfd to vm->irqfds under irqfds_lock, so the irqfd is
never visible to deassign/deinit before its waitqueue entry is in
place, and any EPOLLHUP that fires in the assign window queues
cleanup work that blocks on irqfds_lock until publication is done.

The global nvram_mutex in drivers/char/nvram.c is redundant and unused,
and this triggers compiler warnings on some configurations.
All platform-specific nvram operations already provide their own internal
synchronization, meaning the wrapper-level mutex does not provide any
additional safety.
Remove the nvram_mutex definition along with all remaining lock/unlock
users across PPC32, x86, and m68k code paths, and rely entirely on the
per-architecture nvram implementations for locking.

pci_device_id more idiomatic and compact.
Also drop trailing zeros in the list initializer that the compiler takes
care of then. The driver doesn't use neither .class, .class_mask nor

This patch improves the module cleanup process in the tlclk driver to
prevent potential use-after-free and race conditions.
Currently, the file_operations structure does not specify the .owner
field, which could allow the module to be unloaded while user-space
processes are still interacting with the device. Additionally, the
tlclk_cleanup() function frees the alarm_events memory before ensuring
that blocked processes in the waitqueue are fully awakened and that the
switchover_timer has completed.
To address these cases, this patch:
- Sets '.owner = THIS_MODULE' in tlclk_fops to safely defer module
unloading while the device is in use.
- Updates tlclk_cleanup() to explicitly wake up all blocked readers
(wake_up_all), properly release hardware I/O regions, and safely
delete the timer (timer_delete_sync) prior to freeing memory.

The NI USB adapter sets the END bit in the status word when an error
occurs such as a read being interrupted by the setting of ATN. This
happens for example when a device clear is received from the
controller in charge during a read.
The common driver changes the error return to 0 whenever the END bit
is set in order to avoid errors such as timeout or interrupt to be
reported after the full message has actually been read. The behaviour
of the NI USB adapter in setting the END bit on errors was causing
actual errors (-EINTR, -ETIMEDOUT) not to be reported.
We avoid setting the END bit in the ni_usb_gpib driver when an error
is reported in error_code of the status from the adaptor.

The .driver_data member of the various struct pci_device_id arrays were
initialized by list expressions. This isn't easily readable if you're
not into PCI. Using named initializers is more explicit and thus easier
to parse. Also skip explicit assignments of 0 (which the compiler takes
care of).
The secret plan is to make struct pci_device_id::driver_data an
anonymous union (similar to
https://lore.kernel.org/all/cover.1776579304.git.u.kleine-koenig@baylibre.com/)
and that requires named initializers. But it's also a nice cleanup on
its own.
This change doesn't introduce changes to the compiled pci_device_id
arrays. Tested on x86 and arm64.

The DATA-packet handler in rxrpc_input_call_event() and the RESPONSE
handler in rxrpc_verify_response() copy the skb to a linear one before
calling into the security ops only when skb_cloned() is true. An skb
that is not cloned but still carries externally-owned paged fragments
(e.g. SKBFL_SHARED_FRAG set by splice() into a UDP socket via
__ip_append_data, or a chained skb_has_frag_list()) falls through to
the in-place decryption path, which binds the frag pages directly into
the AEAD/skcipher SGL via skb_to_sgvec().
Extend the gate to also unshare when skb_has_frag_list() or
skb_has_shared_frag() is true. This catches the splice-loopback vector
and other externally-shared frag sources while preserving the
zero-copy fast path for skbs whose frags are kernel-private (e.g. NIC
page_pool RX, GRO). The OOM/trace handling already in place is reused.

- Fix spurious failures in rseq self-tests (Mark Brown)
- Fix rseq rseq::cpu_id_start ABI regression due to
TCMalloc's creative use of the supposedly read-only field.
The fix is to introduce a new ABI variant based on
a new (larger) rseq area registration size, to keep
the TCMalloc use of rseq backwards compatible on new kernels.
(Thomas Gleixner)
- Fix wakeup_preempt_fair() for not waking up task (Vincent Guittot)
- Fix s64 mult overflow in vruntime_eligible() (Zhan Xusheng)
