Some UVC 1.1 cameras running in fast isochronous mode tend to spam the
USB host with a lot of empty packets. These packets contain clock
information and are added to the clock buffer but do not add any
accuracy to the calculation. In fact, it is quite the opposite, in our
calculations, only the first and the last timestamp is used, and we only
have 32 slots.
Ignore the samples that will produce less than MIN_HW_TIMESTAMP_DIFF
data.

In some situations, even with a full clock buffer, it does not contain
250msec of data. This results in the driver jumping back from software
to hardware timestapsing creating a nasty artifact in the video.
If the clock buffer is full, use it to calculate the timestamp instead
of defaulting to software stamps, the reduced accuracy is less visible
than jumping from one timestamping mechanism to the other.

Avoid this by tracking the state of the metadata buffer and making sure

Now that we are at it, make sure that we skip buffers of size 1 or 0.
They are not allowed by the spec... but it is a simple check to add and

uvc_ctrl_status_event()
uvc_ctrl_clear_handle()
uvc_pm_put()
uvc_status_put()
uvc_status_stop()
cancel_work_sync()
This will cause a deadlock, since cancel_work_sync will wait for
uvc_ctrl_status_event_work to complete before returning.
Fix this by returning early from uvc_status_stop if we are currently in

When submitting a bio to blk-mq, if the task should sleep after peeking
a cached request, but before it pops it, the plug flushes and calls
blk_mq_free_plug_rqs, freeing the cached_rqs. This creates a
use-after-free bug. Fix this by popping the cached request before any
possible blocking calls if it is suitable for use.
Popping this request first holds a queue reference, so avoid any
serialization races with queue freezes and can safely proceed with
dispatching that request to the driver. This potentially increases a
timing window from when a driver wants to freeze its queue to when
requests stop being dispatched. That scenario is off the fast path
though, and drivers need to appropriately handle requests during a
freeze request anyway.
The downside is the popped element needs to be individually freed when
we performed a bio plug merge. The cached request would have had to be
freed later anyway, but this patch does it inline with building the plug
list instead of after flushing it.

including aggregate NoCs, a high-speed configuration NoC (HSCNOC), a
multimedia NoC, four NSP data NoCs for AI/ML workloads, PCIe inbound and
outbound NoCs, a system NoC, and virtual clock/MC nodes. Bandwidth requests
are communicated to the RPMh hardware through Bus Clock Manager (BCM)
resources via the Resource State Coordinator (RSC).

matches_log_fs() and other audit_match_record() callers intermittently
return -EAGAIN under heavy debug configs (KASAN, lockdep). The audit
record delivery pipeline is asynchronous: landlock_log_denial() queues
the record to audit_queue, and kauditd_thread dequeues and delivers via
netlink. Under debug configs, kauditd scheduling between
audit_log_end() and netlink_unicast() can exceed a syscall round trip
(more than 1 usec), which was the value of the socket timeout used for
the recvfrom() calls.
The observed failure [1] is an EAGAIN error code (-11) which means that
the access record had not arrived within the 1 usec timeout of
recvfrom(). The expected record does arrive, but only after
matches_log_fs() has already returned. It is then consumed by a later
audit_count_records() call, making records.access == 1 instead of 0.
Switch the default socket timeout to the slow value (1 second) so all
audit_match_record() callers wait long enough for kauditd delivery, and
lower it to the fast value (1 usec) only on the two paths that expect no
record: audit_count_records() and the expected_domain_id == 0 probe in
matches_log_domain_deallocated(). audit_init() drains stale records
with the fast timeout (terminating on -EAGAIN once the backlog is empty)
and switches to the patient default before returning. 1 second gives
~10x margin over the observed maximum (~100 ms, while the happy path is
~23 us).
Rename the timeval constants to reflect their new roles:
- audit_tv_dom_drop (1 second) -> audit_tv_default: default socket
timeout, patient enough for asynchronous kauditd delivery.
- audit_tv_default (1 usec) -> audit_tv_fast: fast timeout for paths
that expect no record (drain, audit_count_records(), probes).
Invert the conditional in matches_log_domain_deallocated(). Check
setsockopt returns on both the lower and restore paths; preserve the
first error via !err when the restore fails after a prior error so the
actionable return code is not masked by a bookkeeping failure.

audit_count_records() counts both AUDIT_LANDLOCK_DOMAIN allocation and
deallocation records in records.domain . Domain deallocation is tied to
asynchronous credential freeing via kworker threads
(landlock_put_ruleset_deferred), so the dealloc record can arrive after
the drain in audit_init() and after the preceding audit_match_record()
call. This causes flaky failures in tests that assert an exact
records.domain count: a stale dealloc record from a previous test's
domain inflates the count by one.
Observed on x86_64 under build configurations that delay the kworker
firing the dealloc callback (e.g. coverage instrumentation): the
audit_layout1 tests in fs_test.c intermittently saw records.domain == 2
where 1 was expected. The fix is in the shared helper, so those
existing checks become robust without needing a fs_test.c edit.
Filter audit_count_records() with a regex to skip records containing
deallocation status. The remaining domain records (allocation, emitted
synchronously during landlock_log_denial()) are deterministic.
Deallocation records are already tested explicitly via
matches_log_domain_deallocated() in audit_test.c, which uses its own
domain-ID-based filtering and longer timeout.
With this filter in place, re-add the records.domain == 0 checks that
were removed in commit 3647a4977f ("selftests/landlock: Drain stale
audit records on init") as a workaround for this race.

This fixes an inconsistency where io_nop() called req_set_fail()
based on ret, but passed just nop->result to userspace.
Originally, ret is a even copy of nop->result, but is set to an error
when such happens subsequently. Now that's also passed to userspace.

rocket_ioctl_create_bo() inserts a GEM handle into the file's IDR via
drm_gem_handle_create() early on, then performs several operations that
can fail (sgt allocation, drm_mm insert, iommu_map). If any fail after
the handle is live, the error path calls drm_gem_shmem_object_free()
which kfree's the object without removing the handle from the IDR.
This leaves a dangling handle pointing to freed slab memory. Any
subsequent ioctl using that handle (PREP_BO, FINI_BO, SUBMIT) calls
drm_gem_object_lookup() and dereferences freed memory (UAF).
Fix by moving drm_gem_handle_create() to after all fallible operations
succeed, matching the pattern used by panfrost, lima, and etnaviv.
Also fix drm_mm_insert_node_generic() whose return value was silently
overwritten by iommu_map_sgtable() on the next line. Add the missing
error check.

When the kernel is booted with a kunit filter (e.g.,
kunit.filter="speed!=slow"), the kunit executor dynamically allocates
copies of the filtered test suites using kmalloc/kmemdup.
During the initial boot execution, kunit_debugfs_create_suite() creates
debugfs files (such as /sys/kernel/debug/kunit/<suite>/run) and
permanently stores a pointer to the dynamically allocated suite in the
inode's i_private field.
Previously, the executor freed this dynamically allocated suite_set
immediately after executing the boot-time tests. Because the debugfs
nodes were not destroyed, any subsequent interaction with the debugfs
`run` file from userspace triggered a use-after-free (UAF). On systems
with architectural capabilities, like CHERI RISC-V, this resulted in
an immediate fatal hardware exception due to the invalidation of the
capability tags on the reclaimed memory. On other architectures, it
resulted in silent memory corruption.
Fix this UAF by properly coupling the lifetime of the filtered suite
memory allocation to the lifetime of the kunit subsystem and its
associated VFS nodes. Ownership of the boot-time suite_set is now
transferred to a global tracker ('kunit_boot_suites'), and the memory
is cleanly released in kunit_exit() during module teardown.

SCMI transport drivers are initialized first and then the control is passed
to the SCMI core stack: some of these transports are dependent also on some
external subsytem which will have to be initialized upfront, before the
transport driver itself can be deemed operational.
Transport drivers like virtio or optee need a way to defer the core SCMI
probing till they are fully initialized and operational and also a way to
pass back the device reference to be used as a supplier while building the
devlink relations.
SCMI transport drivers can be probed multiple times when used in a multiple
instance configuration but the capability to carry-on with multiple probes
depends on the support provided by the underlying transport driver.
This change will also allow for the removal of the frowned-upon trick of
registering a platform driver only after the end of the transport drivers
porbe to avoid explicit probe deferrals.

ops_dequeue() can race with finish_dispatch() and spuriously trigger the
"queued task must be in BPF scheduler's custody" warning.
ops_dequeue() snapshots p->scx.ops_state via atomic_long_read_acquire()
and then, in the SCX_OPSS_QUEUED arm, asserts that SCX_TASK_IN_CUSTODY
is set. The two reads are not atomic w.r.t. a concurrent
finish_dispatch() running on another CPU:
CPU 1 CPU 2
===== =====
dequeue_task_scx()
ops_dequeue()
opss = read_acquire(ops_state)
= SCX_OPSS_QUEUED
finish_dispatch()
cmpxchg ops_state:
SCX_OPSS_QUEUED -> SCX_OPSS_DISPATCHING [succeeds]
dispatch_enqueue(SCX_DSQ_GLOBAL,
SCX_ENQ_CLEAR_OPSS)
call_task_dequeue()
p->scx.flags &= ~SCX_TASK_IN_CUSTODY
WARN_ON_ONCE(!(p->scx.flags &
SCX_TASK_IN_CUSTODY))
/* opss is stale: QUEUED,
* but task already claimed */
set_release(ops_state, SCX_OPSS_NONE)
The race has been observed via two distinct call chains: the most common
goes through sched_setaffinity(), a rarer variant through
sched_change_begin().
For SCX_DSQ_GLOBAL / SCX_DSQ_BYPASS, dispatch_enqueue() clears
SCX_TASK_IN_CUSTODY before clearing ops_state to SCX_OPSS_NONE
(intentional, to avoid concurrent non-atomic RMW of p->scx.flags against
ops_dequeue()). The window between those two writes is exactly what
ops_dequeue() observes as "QUEUED without custody".
The observed state is not actually inconsistent, it just means CPU 1 has
already claimed the task and the QUEUED value held by CPU 2 is stale.
Re-read ops_state in that case; the next read is guaranteed to return
SCX_OPSS_DISPATCHING or SCX_OPSS_NONE, both of which exit the switch
cleanly. The retry is bounded: once IN_CUSTODY is cleared, ops_state has
already advanced past QUEUED for this dispatch cycle, and a fresh QUEUED
would require re-enqueue under p's rq lock, which CPU 2 holds.
Changes in v2:
- Use READ_ONCE() for p->scx.flags to ensure fresh reads and prevent
compiler reordering in the lockless path
- Add cpu_relax() to reduce power consumption and improve performance
during the spin-wait
- Use unlikely() to optimize branch prediction for the common case
- Expand the in-code comment to document the race condition and
bounded retry guarantee
