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

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.

Add a SND_PCI_QUIRK entry for the HP Pavilion Laptop 16-ag0xxx
(subsystem 0x103c:0x8cbc, Realtek ALC245). The
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
LED handler, which is what this machine needs.
Tested on the affected hardware: both the mute and mic-mute key
LEDs respond correctly to the keyboard hotkeys after this change.

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.

First of all, it has to be 'default n' (small letter n), otherwise
it looks for CONFIG_N which is absent and in case of appearance
will enable something unrelated. Second and most important is that
'n' *is* the default 'default' already. Hence just drop malformed

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.

The Lenovo Legion 7 16ITHG6 uses codec SSID 17aa:3855, but its PCI
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.
Add a codec SSID quirk for 17aa:3855 before the conflicting PCI SSID
quirk so that the Legion 7 16ITHG6 uses ALC287_FIXUP_LEGION_16ITHG6.
This restores CS35L41 firmware loading and binds both speaker
amplifiers.

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 pointed out that the driver could drop PAGE_SIZE from the
pgsize_bitmap. That is technically allowed but nothing does it, and
such an iommu_domain would not be used with the DMA API today.
Still, it is against the design and it is trivial to fix up. Lift
the PT_WARN_ON to the if branch and just skip the fast path.

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 hwmon sysfs naming convention uses
temp[1-*]_input for temperature channels.
Documentation/hwmon/sy7636a-hwmon.rst currently documents
temp0_input, while the driver uses the standard hwmon
temperature channel interface.
Update the documentation to use temp1_input.

Previously BAR resource requests and the corresponding pci_iomap()
were performed on-demand and without synchronisation, which was racy.
Rather than add synchronisation, it's simplest to address this by
doing both activities from vfio_pci_core_enable().
The resource allocation and/or pci_iomap() can still fail; their
status is tracked and existing calls to vfio_pci_core_setup_barmap()
will fail in a similar way to before. This keeps the point of failure
as observed by userspace the same, i.e. failures to request/map unused
BARs are benign.

With the support of nested lazy mmu sections it can happen that
arch_enter_lazy_mmu_mode() is being called twice without a call of
arch_leave_lazy_mmu_mode() in between, as the lazy_mmu_*() helpers
are not disabling preemption when checking for nested lazy mmu
sections.
This is a problem when running as a Xen PV guest, as
xen_enter_lazy_mmu() and xen_leave_lazy_mmu() don't tolerate this
case.
Fix that in xen_enter_lazy_mmu() and xen_leave_lazy_mmu() in order
not to hurt all other lazy mmu mode users.

SMB2 READ response validation in cifs_readv_receive() and
handle_read_data() checks data_offset + data_len against the received
buffer length. Both values are attacker-controlled fields from the
server response and are stored as unsigned int, so the addition can
wrap before the bounds check:
fs/smb/client/transport.c:1259
if (!use_rdma_mr && (data_offset + data_len > buflen))
fs/smb/client/smb2ops.c:4839
else if (buf_len >= data_offset + data_len)
A malicious SMB server can use this to bypass validation. In the
non-encrypted receive path the client attempts an oversized socket
read and stalls for the SMB response timeout (180 seconds) before
reconnecting. In the SMB3 encrypted path, runtime testing shows the
malformed length can reach copy_to_iter() in handle_read_data() with
attacker-controlled size, where usercopy hardening stops the oversized
copy before bytes reach userspace.
Guard both call sites with check_add_overflow(), which is already
used elsewhere in this subsystem (smb2pdu.c). On overflow, treat the
response as malformed and reject with -EIO.
