ba9d308ccd nvme-apple: drop invalid put of admin queue reference count
Commit 03b3bcd319 ("nvme: fix admin request_queue lifetime") moved the
admin queue reference ->put call into nvme_free_ctrl() - a controller
device release callback performed for every nvme driver doing
nvme_init_ctrl().

nvme-apple sets refcount of the admin queue to 1 at allocation during the
probe function and then puts it twice now:

nvme_free_ctrl()
  blk_put_queue(ctrl->admin_q) // #1
  ->free_ctrl()
    apple_nvme_free_ctrl()
      blk_put_queue(anv->ctrl.admin_q) // #2

Note that there is a commit 941f7298c7 ("nvme-apple: remove an extra
queue reference") which intended to drop taking an extra admin queue
reference.  Looks like at that moment it accidentally fixed a refcount
leak, which existed since the driver's introduction.  There were two ->get
calls at driver's probe function and a single ->put inside
apple_nvme_free_ctrl().

However now after commit 03b3bcd319 ("nvme: fix admin request_queue
lifetime") the refcount is imbalanced again.  Fix it by removing extra
->put call from apple_nvme_free_ctrl().  anv->dev and ctrl->dev point to
the same device, so use ctrl->dev directly for simplification.  Compile
tested only.

e80e39f255 nvme-core: fix parameter name in comment
In the declaration of the structure "core_quirks[]", in the comment
referred to the devices "Kioxia CD6-V Series / HPE PE8030", the
parameter "default_ps_max_latency_us" is reported in a wrong way:

nvme_core.default_ps_max_latency=0

The correct form is, instead:

nvme_core.default_ps_max_latency_us=0

aade8abd8b nvmet: avoid recursive nvmet-wq flush in nvmet_ctrl_free
nvmet_tcp_release_queue_work() runs on nvmet-wq and can drop the
final controller reference through nvmet_cq_put(). If that triggers
nvmet_ctrl_free(), the teardown path flushes ctrl->async_event_work on
the same nvmet-wq.

Call chain:

 nvmet_tcp_schedule_release_queue()
   kref_put(&queue->kref, nvmet_tcp_release_queue)
     nvmet_tcp_release_queue()
       queue_work(nvmet_wq, &queue->release_work) <--- nvmet_wq
         process_one_work()
           nvmet_tcp_release_queue_work()
             nvmet_cq_put(&queue->nvme_cq)
               nvmet_cq_destroy()
                 nvmet_ctrl_put(cq->ctrl)
                   nvmet_ctrl_free()
                     flush_work(&ctrl->async_event_work) <--- nvmet_wq

                      Previously Scheduled by :-
		        nvmet_add_async_event
		          queue_work(nvmet_wq, &ctrl->async_event_work);

This trips lockdep with a possible recursive locking warning.

There is also no need to flush async_event_work from controller
teardown. The admin queue teardown already fails outstanding AER
requests before the final controller put :-

 nvmet_sq_destroy(admin sq)
    nvmet_async_events_failall(ctrl)

The controller has already been removed from the subsystem list before
nvmet_ctrl_free() quiesces outstanding work.

Replace flush_work() with cancel_work_sync() so a pending
async_event_work item is canceled and a running instance is waited on
without recursing into the same workqueue.

extract-cert: Wrap key_pass with '#ifdef USE_PKCS11_ENGINE'
A recent strengthening of -Wunused-but-set-variable (enabled with -Wall)
in clang under a new subwarning, -Wunused-but-set-global, points out an
unused static global variable in certs/extract-cert.c:

  certs/extract-cert.c:46:20: error: variable 'key_pass' set but not used [-Werror,-Wunused-but-set-global]
     46 | static const char *key_pass;
        |                    ^

After commit 558bdc45df ("sign-file,extract-cert: use pkcs11 provider
for OPENSSL MAJOR >= 3"), key_pass is only used with the OpenSSL engine
API, not the new provider API. Wrap key_pass's declaration and
assignment with '#ifdef USE_PKCS11_ENGINE' so that it is only included
with its use to clear up the warning. While this is a little uglier than
just marking key_pass with the unused attribute, this will make it
easier to clean up all code associated with the use of the engine API if
it were ever removed in the future. While in the area, use a tab for
the key_pass assignment line to match the rest of the file.

df410ad40c selftests: Fix runner.sh for non-bash shells
Commit 2964f6b816 ("selftests: Use ktap helpers for runner.sh") added a
number of bashisms and updated the interpreter specified for the script to
be /bin/bash to reflect this. Unfortunately this does not actually achieve
anything in production since the main way runner.sh is invoked is from the
top level run_kselftest.sh which sources it rather than running it as a
separate script and specifies the shell as /bin/sh. This means that on
systems where /bin/sh is not bash (such as Debian where /bin/sh defaults to
being dash) we see failures:

./run_kselftest.sh: 195: ./kselftest/runner.sh: Syntax error: "(" unexpected (expecting "}")

These bashisms come from this part of the change:

  4. In runner.sh run_one(), get the return value and use ktap helpers for
     all pass/fail reporting. This allows counting pass/fail numbers in the
     main process.

which uses a bash array to track all the subtests being run. Convert this
to use a simple flat variable instead.

93edbf1782 selftests: Fix runner.sh busybox support
Commit 2964f6b816 ("selftests: Use ktap helpers for runner.sh") added an
import of ktap_helper.sh to runner.sh in order to standardise on these for
output formatting. Rather than build on the existing requirement for the
user to supply BASE_DIR to find the helpers it uses some magic which
features a use of "readlink -e". Unfortunately the -e option is a GNU
extension and is not available in at least busybox, meaning that runner.sh
starts failing:

./run_kselftest.sh: 5: ./kselftest/runner.sh: Bad substitution
./run_kselftest.sh: 5: .: cannot open ./ktap_helpers.sh: No such file

Fix this by using the already required BASE_DIR to locate the helper
library.

cad6f32665 selftests: Deescalate error reporting
Commit 7e47389142 ("selftests: Preserve subtarget failures in
all/install") updated the propagation of errors from indivdual kselftest
targets to be similar to that seen with FORCE_TARGETS.  While it would
be really nice to be in a position to do this currently it is premature
to do this as the default behaviour.

At present we default to trying to build all selftests but a combination
of code quality issues and build dependencies mean that it is almost
certain that at least one of them will fail to build (for example,
several depend on clang so don't work in a GCC container) and a top
level failure in the kselftest build reported.  Further, the resulting
failures mean that the install target does not run at all so any build
problem is escallated to a complete failure to produce a kselftest
tarball so CI systems that run into issues loose all selftests coverage.
This has been causing disruption to a range of CI systems including
KernelCI, mine and Arm's internal one.

Revert the commit, users who need this behaviour should be able to use
FORCE_TARGETS for the time being.  At present users that do this (such
as linux-next) are most likely building a subset of targets known to
succeed in their environments.

35aff528f7 drm/xe/eustall: Fix drm_dev_put called before stream disable in close
In xe_eu_stall_stream_close(), drm_dev_put() is called before the
stream is disabled and its resources are freed. If this drops the
last reference, the device structures could be freed while the
subsequent cleanup code still accesses them, leading to a
use-after-free.

Fix this by moving drm_dev_put() after all device accesses are
complete. This matches the ordering in xe_oa_release().

4096fd0e8e clockevents: Add missing resets of the next_event_forced flag
The prevention mechanism against timer interrupt starvation missed to reset
the next_event_forced flag in a couple of places:

    - When the clock event state changes. That can cause the flag to be
      stale over a shutdown/startup sequence

    - When a non-forced event is armed, which then prevents rearming before
      that event. If that event is far out in the future this will cause
      missed timer interrupts.

    - In the suspend wakeup handler.

That led to stalls which have been reported by several people.

Add the missing resets, which fixes the problems for the reporters.

88f059f6f6 drm/gpuvm: Do not prepare NULL objects
Statis analysis issue:

drm_gpuvm_prepare_range issues an exec_object_prepare call to all
drm_gem_objects mapped between addr and addr + range.  However, it is
possible (albeit very unlikely) that the objects found through
drm_gpuvm_for_each_va_range (as connected to va->gem) are NULL, as seen
in other functions such as drm_gpuva_link and drm_gpuva_unlink_defer.

Do not prepare NULL objects.

1d2c535315 sched_ext: scx_qmap: replace FIFO queue maps with arena-backed lists
Arena simplifies verification and allows more natural programming.
Convert scx_qmap to arena as preparation for further sub-sched work.

Replace the five BPF_MAP_TYPE_QUEUE maps with doubly-linked lists in
arena, threaded through task_ctx. Each queue is a struct qmap_fifo with
head/tail pointers and its own per-queue bpf_res_spin_lock.

qmap_dequeue() now properly removes tasks from the queue instead of
leaving stale entries for dispatch to skip.

v2:
- Remove duplicate QMAP_TOUCH_ARENA() in qmap_dump_task (Andrea).
- Update file-level description for arena-backed lists (Andrea).

a6628db4f6 sched_ext: scx_qmap: move task_ctx into a BPF arena slab
Arena simplifies verification and allows more natural programming.
Convert scx_qmap to arena as preparation for further sub-sched work.

Allocate per-task context from an arena slab instead of storing it
directly in task_storage. task_ctx_stor now holds an arena pointer to
the task's slab entry. Free entries form a singly-linked list protected
by bpf_res_spin_lock; slab exhaustion triggers scx_bpf_error().

The slab size is configurable via the new -N option (default 16384).

Also add bpf_res_spin_lock/unlock declarations to common.bpf.h.

Scheduling logic unchanged.

v2: Add task_ctx_t typedef for struct task_ctx __arena (Emil).

Move scheduler state from BSS globals and a percpu array map

71096693e8 drm/i915/reset: Disable execlist per-engine reset for display reset tests
The display reset only happens from the full reset path. We must
therefore force execlist submission to always take the full reset
path and not the per-engine reset path. Currently the display
reset tests are in fact not testing display resets at all on
platforms using execlist submission. Ring submission and GuC
submission always take the full path anyway.

Also disable the engine reset inside __intel_gt_set_wedged() so
that we simulate the intel_gt_gpu_reset_clobbers_display() behavior
as closely as possible also when taking the full wedge path.

The slight race between the separate intel_display_reset_test()
calls in the overall reset path is harmless. kms_busy will keep
the modparam fixed during the test, and even if someone were to
fiddle with the modparam manually nothing bad should happen if
the calls return different values.

Only i915 uses the pending_fb_pin counter to potentially whack
the GPU harder if the display gets nuked during a GPU reset.
Move the atomic counter into the i915 specific bits of code, so
that we don't need to worry about on the display side.

For some reason the overlay code kept the pending_fb_pin counter
elevated for longer than just for the pin, but from now on it'll
just cover the actual pinning part.

    deprecation. (Jori Koolstra)
 
  - Improve selftest compiler compatibility by avoiding initializer
    on variable-length array. (Manish Honap)
 
  - Define new uAPI for drivers supporting migration to advise user-
    space of new initial data for reducing target startup latency.
    Implemented for mlx5 vfio-pci variant driver. (Yishai Hadas)
 
  - Enable vfio selftests on aarch64, not just cross-compiles reporting
    arm64. (Ted Logan)
 
  - Update vfio selftest driver support to include additional DSA
    devices. (Yi Lai)

    avoiding a build failure seen in hisi_acc variant driver without
    debugfs otherwise. (Arnd Bergmann)
 
  - Add support for the s390 ISM (Internal Shared Memory) device via
    a new variant driver.  The device is unique in the size of its BAR
    space (256TiB) and lack of mmap support. (Julian Ruess)
 
  - Enforce that vfio-pci drivers implement a name in their ops
    structure for use in sequestering SR-IOV VFs. (Alex Williamson)
 
  - Prune leftover group notifier code. (Paolo Bonzini)
