Pull VFIO fixes from Alex Williamson:
- Convert vfio-pci BAR resource requests and iomaps initialization
from a lazy, on-demand model to an eager pre-allocation model to
avoid races while preserving legacy error behavior. Fix unchecked
barmap access in dma-buf export path (Matt Evans)
- Introduce an implicit unsigned cast in converting vfio-pci device
offsets to region indexes, closing a potential out-of-bounds
access through the vfio_pci_ioeventfd() interface (Matt Evans)
- Fix a dma-buf kref underflow and stuck wait_for_completion() when
closing a previously revoked dma-buf (Alex Williamson)

After commit 03f920936977 ("PCI: controller: Validate max-link-speed"),
pcie->gen stopped being assigned and as a result the established PCIe link
would stop supporting Gen3 speeds on 2712 since pcie->gen is used to
populate LnkCntl2 and LnkCap in brcm_pcie_set_gen().
If the 'max-link-speed' property is not specified, or it exceeds Gen3,
resort to the HW defaults.

For two reasons:
1) An opcode cannot block inside io_uring_enter() doing submissions, as
it'll stall the submission side pipeline.
2) Ending up in sb_start_write() -> __sb_start_write() ->
percpu_down_read_freezable() introduces a new lockdep edge, which it
correctly complains about.
Check if the socket type is AF_UNIX and has a non-empty pathname. If it
does, mark it REQ_F_FORCE_ASYNC to punt the submission to io-wq rather
than attempt to do it inline.

UTS_RELEASE evaluates to a static string and changes quite easily (e.g.
uncommitted changes in the source tree or new commits). So when checking
if a patch introduces changes to the resulting binary each usage of
UTS_RELEASE is source of annoyance.
Instead of using UTS_RELEASE directly use init_utsname()->release which
evaluates to the same string but with that a change of UTS_RELEASE
doesn't affect msm_disp_snapshot_util.o or msm_gpu.o.

When vfs_mkdir() fails, the error code is not extracted from the
returned error pointer. This causes mkdir_error to be reached with
ret=0, which leads to returning ERR_PTR(0) (NULL) instead of a
proper error pointer.
Fix this by extracting the error code from the error pointer when
vfs_mkdir() fails.

Commit 778031e1658d ("ALSA: hda/ca0132: Set HP/Speaker
auto-detect default from headphone pin verb") enables HP/Speaker
auto-detect by default when the headphone pin supports presence detect.
With auto-detect enabled, ca0132_select_out() and ca0132_alt_select_out()
choose the output from jack presence instead of the manual HP/Speaker
selection. This means selecting speaker output while headphones are
plugged in updates the control state, but audio still routes to the
headphones.
Treat an explicit manual output selection as a request to leave
auto-detect mode. Clear the HP/Speaker auto-detect switch before applying
the manual selection, and notify userspace so the auto-detect control
state is updated in mixers. Do this for both the normal HP/Speaker
Playback Switch and the alternate Output Select control used by desktop
cards.
This keeps auto-detect enabled by default for devices with jack presence
detection, while preserving the expected behavior that a manual output
choice takes effect immediately.

waits for any running timer callback to complete (like timer_delete_sync())
and permanently disarms the timer so it cannot be re-armed afterwards,
making re-arming prevention unconditional and self-documenting.
The re-arming property is also required because otherwise:
1. context 0 (batadv_tp_recv_ack()) checks in
batadv_tp_reset_sender_timer() if sending is still 1 -> it is
2. context 1 changes in batadv_tp_sender_shutdown() sending to 0 and in
this process forces the kthread to stop timer in
batadv_tp_sender_cleanup()
3. context 0 continues in batadv_tp_reset_sender_timer() and rearms the
timer -> but the reference for it is already gone

batadv_frag_skb_buffer() is called by batadv_batman_skb_recv() when a
BATADV_UNICAST_FRAG packet is received. Once all fragments are collected
and the packet is reassembled, batadv_recv_frag_packet() calls
batadv_batman_skb_recv() again to process the defragmented payload.
A malicious sender can craft a BATADV_UNICAST_FRAG packet whose reassembled
payload is itself a BATADV_UNICAST_FRAG packet (matryoshka-style nesting).
Each nesting level recurses through batadv_batman_skb_recv() without bound,
growing the kernel stack until it is exhausted.
Since refragmentation or fragments in fragments are not actually allowed,
discard all packets which are still BATADV_UNICAST_FRAG packets after the
defragmentation process.

Add a SND_PCI_QUIRK entry for the HP Pavilion Laptop 16-ag0xxx

ALC245_FIXUP_HP_X360_MUTE_LEDS fixup is already used by the
neighbouring HP Pavilion Aero Laptop 13-bg0xxx (0x103c:0x8cbd);
it chains the master-mute COEF handler with the GPIO mic-mute

snd_hda_ctl_add() dereferences kctl->id.subdevice without checking
whether kctl is NULL. Multiple callers in sound/hda/codecs/ca0132.c
pass the return value of snd_ctl_new1() directly to snd_hda_ctl_add()
without a NULL check:
return snd_hda_ctl_add(codec, nid, snd_ctl_new1(&knew, codec));
snd_ctl_new1() returns NULL when the underlying snd_ctl_new() fails
on memory allocation (kzalloc_flex),which can occur under memory
pressure or via fault injection.
Add a NULL check at the entry of snd_hda_ctl_add(), matching the
pattern already used by snd_ctl_add_replace() at the same call
path (sound/core/control.c:515). Return -EINVAL to let callers
handle the error gracefully.

uaudio_transfer_buffer_setup() calls dma_get_sgtable() and then passes
the sg_table to uaudio_iommu_map_xfer_buf() without checking whether sg
table construction succeeded. If dma_get_sgtable() fails, the sg_table
contents are not valid.
uaudio_iommu_map_pa() also ignores iommu_map() failures for the event and
transfer rings and still returns the allocated IOVA to the QMI response.
That can expose an unmapped IOVA to the audio DSP. For transfer rings,
the failed mapping also leaves the IOVA allocator state marked in use.
Check both operations. Free the coherent transfer buffer when sg table
construction fails, free the sg table when transfer-buffer IOMMU mapping
fails, and release the transfer-ring IOVA if iommu_map() fails. Also
return the existing event-ring IOVA when the event ring is already mapped,
matching the pre-split helper behavior.

lsdc_pci_probe() initializes KMS polling before setting up vblank support,
requesting the IRQ and registering the DRM device. If any of those later
steps fails, probe returns without finalizing polling. The driver also
never finalizes polling on regular removal.
Use drmm_kms_helper_poll_init() so polling is tied to the DRM device
lifetime and automatically finalized on probe failure and device removal.
This issue was identified during our ongoing static-analysis research while
reviewing kernel code.

SSID is 17aa:3811. The latter is now also used by the Legion S7 15IMH05
quirk, which is matched before codec SSID fallback and incorrectly
routes Legion 7 16ITHG6 machines to ALC287_FIXUP_LEGION_15IMHG05_SPEAKERS.
That fixup does not bind the CLSA0101 CS35L41 companion amplifiers,
making the built-in speakers silent even though playback appears to be
active.

Sashiko noticed a mismatch of units in this math: num_leaves is
actually the number of leaf *entries* (so a 16-item contiguous leaf
is one num_leaves), while index is in items. The mismatch in maths
causes __map_range_leaf() to exit early instead of efficiently
filling a larger range of contiguous PTEs.
The early exit is caught by the functions above and then
__map_range_leaf() is re-invoked, so there is no functional issue.
Correct the misuse of units by adjusting num_leaves with the leaf
size and avoid the performance cost of looping externally.
There are also some mismatched types for num_leaves; simplify
things to remove the duplicated calculations.

Sashiko noticed a latent bug where the map error flow called iommu_unmap()
which calls iommu_debug_unmap_begin()/iommu_debug_unmap_end() however
since this is an error path the map flow never actually established the
original iommu_debug_map() it will malfunction.
Lift the unmap error handling into iommu_map_nosync() and reorder it so
the trace_map()/iommu_debug_map() records the partial mapping and then
immediately unmaps it. This avoid creating the unbalanced tracking and
provides saner tracing instead of a unmap unmatched to any map.

Sashiko noticed a few issues in this path, and a few more were
found on review. Tidy them up further. These are intertwined
because the debug code depends on some of the WARN_ONs to function
right:
Lift into iommu_map_nosync():
- The might_sleep_if()
- 0 pgsize_bitmap WARN_ON
- Promote the illegal domain->type to a WARN_ON
- WARN_ON for illegal gfp flags
Then remove the return 0 since it is now safe to call
iommu_debug_map().
Lift into __iommu_unmap():
- 0 pgsize_bitmap WARN_ON
- Promote the illegal domain->type to a WARN_ON
- iommu_debug_unmap_begin()
This now pairs with the unconditional iommu_debug_map() on the
mapping side. Thus iommu debugging now works for iommupt along
with some of the other debugging features.

A typo, likely from a rebase, inverted the condition and caused
errors to be lost. Fix it to be "if (ret)".
This was breaking iommu_create_device_direct_mappings() on drivers
that don't use iommupt and don't fully set up their domain in
alloc_pages() (i.e., SMMUv2). In this case the first call of
iommu_create_device_direct_mappings() should fail due to the
incompletely initialized domain. Since it wrongly returns success,
the second call to iommu_create_device_direct_mappings() doesn't
happen and IOMMU_RESV_DIRECT is never set up.

The TCM_LOOP LUN creation process calls device_register() to create the

the TCM_LOOP bus to create and register the scsi_host. However, if the
scsi_host memory allocation fails or scsi_add_host() fails, the
device_register() process still returns success. Subsequently, when the
user binds the LUN to a specific backend device, it accesses the NULL or
freed scsi_host.

The ISCI completion tasklet is initialized in isci_host_alloc()
(drivers/scsi/isci/init.c:496) and scheduled from both MSI-X and legacy
interrupt handlers (drivers/scsi/isci/host.c:223,613).
isci_host_deinit() stops the controller and waits for stop completion,
but it never kills completion_tasklet before teardown continues. A
top-of-function tasklet_kill() is not sufficient here: interrupts are
only disabled when isci_host_stop_complete() runs, so until
wait_for_stop() returns the IRQ handlers can still requeue the
tasklet. The tasklet callback also re-enables interrupts after draining
completions, so killing the tasklet before the source is quiesced leaves
the same race open.
Once wait_for_stop() returns, no further IRQ-driven scheduling can
occur. Kill completion_tasklet there so teardown cannot race a queued
tasklet running on a dead ihost. On remove or unload, the stale callback
can otherwise dereference ihost and touch ihost->smu_registers after the
host lifetime ends.
A UML + KASAN analogue reproduced the failure class both with no
tasklet_kill() and with tasklet_kill() placed before source quiesce, and
stayed clean once the kill happened after quiescing the scheduling
source.
This mirrors commit f6ab594672d4 ("scsi: aic94xx: fix use-after-free in
device removal path"), but ISCI needs the kill after wait_for_stop().
