26c82ec5ad wifi: rtw89: wow: add reason codes for disassociation in WoWLAN mode
[ Upstream commit 2fd8f953f2 ]

Some APs disconnect clients by sending a Disassociation frame
rather than a Deauthentication frame. Since these frames use
different reason codes in WoWLAN mode, this commit adds support
for handling Disassociation to prevent missed disconnection events.

faac634c27 wifi: rtw89: mac: correct page number for CSI response
[ Upstream commit aa2a44d0d2 ]

For beamforming procedure, hardware reserve memory page for CSI response.
The unit of register is (value - 1), so add one accordingly as expected.

715c263119 iommu/amd: move wait_on_sem() out of spinlock
[ Upstream commit d2a0cac105 ]

With iommu.strict=1, the existing completion wait path can cause soft
lockups under stressed environment, as wait_on_sem() busy-waits under the
spinlock with interrupts disabled.

Move the completion wait in iommu_completion_wait() out of the spinlock.
wait_on_sem() only polls the hardware-updated cmd_sem and does not require
iommu->lock, so holding the lock during the busy wait unnecessarily
increases contention and extends the time with interrupts disabled.

b820735643 wifi: libertas: fix WARNING in usb_tx_block
[ Upstream commit d66676e6ca ]

The function usb_tx_block() submits cardp->tx_urb without ensuring that
any previous transmission on this URB has completed. If a second call
occurs while the URB is still active (e.g. during rapid firmware loading),
usb_submit_urb() detects the active state and triggers a warning:
'URB submitted while active'.

Fix this by enforcing serialization: call usb_kill_urb() before
submitting the new request. This ensures the URB is idle and safe to reuse.

65bc40fea4 iommu/arm-smmu-v3: Improve CMDQ lock fairness and efficiency
[ Upstream commit df180b1a4c ]

The SMMU CMDQ lock is highly contentious when there are multiple CPUs
issuing commands and the queue is nearly full.

The lock has the following states:
 - 0:		Unlocked
 - >0:		Shared lock held with count
 - INT_MIN+N:	Exclusive lock held, where N is the # of shared waiters
 - INT_MIN:	Exclusive lock held, no shared waiters

When multiple CPUs are polling for space in the queue, they attempt to
grab the exclusive lock to update the cons pointer from the hardware. If
they fail to get the lock, they will spin until either the cons pointer
is updated by another CPU.

The current code allows the possibility of shared lock starvation
if there is a constant stream of CPUs trying to grab the exclusive lock.
This leads to severe latency issues and soft lockups.

Consider the following scenario where CPU1's attempt to acquire the
shared lock is starved by CPU2 and CPU0 contending for the exclusive
lock.

CPU0 (exclusive)  | CPU1 (shared)     | CPU2 (exclusive)    | `cmdq->lock`
--------------------------------------------------------------------------
trylock() //takes |                   |                     | 0
                  | shared_lock()     |                     | INT_MIN
                  | fetch_inc()       |                     | INT_MIN
                  | no return         |                     | INT_MIN + 1
                  | spins // VAL >= 0 |                     | INT_MIN + 1
unlock()          | spins...          |                     | INT_MIN + 1
set_release(0)    | spins...          |                     | 0 see[NOTE]
(done)            | (sees 0)          | trylock() // takes  | 0
                  | *exits loop*      | cmpxchg(0, INT_MIN) | 0
                  |                   | *cuts in*           | INT_MIN
                  | cmpxchg(0, 1)     |                     | INT_MIN
                  | fails // != 0     |                     | INT_MIN
                  | spins // VAL >= 0 |                     | INT_MIN
                  | *starved*         |                     | INT_MIN

[NOTE] The current code resets the exclusive lock to 0 regardless of the
state of the lock. This causes two problems:
1. It opens the possibility of back-to-back exclusive locks and the
   downstream effect of starving shared lock.
2. The count of shared lock waiters are lost.

To mitigate this, we release the exclusive lock by only clearing the sign
bit while retaining the shared lock waiter count as a way to avoid
starving the shared lock waiters.

Also deleted cmpxchg loop while trying to acquire the shared lock as it
is not needed. The waiters can see the positive lock count and proceed
immediately after the exclusive lock is released.

Exclusive lock is not starved in that submitters will try exclusive lock
first when new spaces become available.

cf2d06c9fd dm: remove fake timeout to avoid leak request
[ Upstream commit f3a9c95a15 ]

Since commit 15f73f5b3e ("blk-mq: move failure injection out of
blk_mq_complete_request"), drivers are responsible for calling
blk_should_fake_timeout() at appropriate code paths and opportunities.

However, the dm driver does not implement its own timeout handler and
relies on the timeout handling of its slave devices.

If an io-timeout-fail error is injected to a dm device, the request
will be leaked and never completed, causing tasks to hang indefinitely.

Reproduce:
1. prepare dm which has iscsi slave device
2. inject io-timeout-fail to dm
   echo 1 >/sys/class/block/dm-0/io-timeout-fail
   echo 100 >/sys/kernel/debug/fail_io_timeout/probability
   echo 10 >/sys/kernel/debug/fail_io_timeout/times
3. read/write dm
4. iscsiadm -m node -u

Result: hang task like below

209149bd75 dm: replace -EEXIST with -EBUSY
[ Upstream commit b13ef361d4 ]

The -EEXIST error code is reserved by the module loading infrastructure
to indicate that a module is already loaded. When a module's init
function returns -EEXIST, userspace tools like kmod interpret this as
"module already loaded" and treat the operation as successful, returning
0 to the user even though the module initialization actually failed.

This follows the precedent set by commit 54416fd767 ("netfilter:
conntrack: helper: Replace -EEXIST by -EBUSY") which fixed the same
issue in nf_conntrack_helper_register().

Affected modules:
  * dm_cache dm_clone dm_integrity dm_mirror dm_multipath dm_pcache
  * dm_vdo dm-ps-round-robin dm_historical_service_time dm_io_affinity
  * dm_queue_length dm_service_time dm_snapshot

b4d46b4fb2 wifi: rtw88: Fix inadvertent sharing of struct ieee80211_supported_band data
[ Upstream commit fcac0f23d4 ]

Internally wiphy writes to individual channels in this structure,
so we must not share one static definition of channel list between
multiple device instances, because that causes hard to debug
breakage.

For example, with two rtw88 driven devices in the system, channel
information may get incoherent, preventing channel use.

[ Upstream commit 41be33d3ef ]

I have some rtl8922ae devices with no permanent mac stored in efuse.

It could be properly saved and/or configured from user tools like
NetworkManager, but it would be desirable to be able to initialize it
somehow to get the device working by default.

So, in the same way as with other devices, if the mac address read from
efuse contains zeros, a random mac address is assigned to at least allow
operation, and the user is warned about this in case any action needs to
be considered.

400ca64e87 wifi: rtw88: fix DTIM period handling when conf->dtim_period is zero
[ Upstream commit 9f68fdcdc9 ]

The function rtw_set_dtim_period() accepted an 'int' dtim_period parameter,
while mac80211 provides dtim_period as 'u8' in struct ieee80211_bss_conf.
In IBSS (ad-hoc) mode mac80211 may set dtim_period to 0.

The driver unconditionally wrote (dtim_period - 1) to
REG_DTIM_COUNTER_ROOT, which resulted in 0xFF when dtim_period was 0. This
caused delays in broadcast/multicast traffic processing and issues with
ad-hoc operation.

Convert the function parameter to u8 to match ieee80211_bss_conf and avoid
the underflow by writing 0 when dtim_period is 0.

5d77c36cd4 jfs: nlink overflow in jfs_rename
[ Upstream commit 9218dc26fd ]

If nlink is maximal for a directory (-1) and inside that directory you
perform a rename for some child directory (not moving from the parent),
then the nlink of the first directory is first incremented and later
decremented. Normally this is fine, but when nlink = -1 this causes a
wrap around to 0, and then drop_nlink issues a warning.

The jfsIOWait() thread calls try_to_freeze() but lacks set_freezable(),

ae583f113d ALSA: mixer: oss: Add card disconnect checkpoints
[ Upstream commit 084d5d4441 ]

ALSA OSS mixer layer calls the kcontrol ops rather individually, and
pending calls might be not always caught at disconnecting the device.

For avoiding the potential UAF scenarios, add sanity checks of the
card disconnection at each entry point of OSS mixer accesses.  The
rwsem is taken just before that check, hence the rest context should
be covered by that properly.

bfefacf199 ASoC: fsl: imx-rpmsg: use snd_soc_find_dai_with_mutex() in probe
[ Upstream commit 84faa91585 ]

imx_rpmsg_probe() calls snd_soc_find_dai() without holding client_mutex.
However, snd_soc_find_dai() has lockdep_assert_held(&client_mutex)
indicating callers must hold this lock, as the function iterates over the
global component list.

All other callers of snd_soc_find_dai() either hold client_mutex via the

Use snd_soc_find_dai_with_mutex() instead to fix the missing lock

21207c0037 spi: geni-qcom: Fix abort sequence execution for serial engine errors
[ Upstream commit 96e041647b ]

The driver currently skips the abort sequence for target mode when serial
engine errors occur. This leads to improper error recovery as the serial
engine may remain in an undefined state without proper cleanup, potentially
causing subsequent operations to fail or behave unpredictably.

Fix this by ensuring the abort sequence and DMA reset always execute during
error recovery, as both are required for proper serial engine error
handling.

5a22d4560c drm/amd/display: avoid dig reg access timeout on usb4 link training fail
[ Upstream commit 15b1d7b77e ]

[Why]
When usb4 link training fails, the dpia sym clock will be disabled and SYMCLK
source should be changed back to phy clock. In enable_streams, it is
assumed that link training succeeded and will switch from refclk to
phy clock. But phy clk here might not be on. Dig reg access timeout
will occur.

[How]
When enable_stream is hit, check if link training failed for usb4.
If it did, fall back to the ref clock to avoid reg access timeout.

f1c5fcf80d spi: spi-mem: Protect dirmap_create() with spi_mem_access_start/end
[ Upstream commit 53f826ff5e ]

spi_mem_dirmap_create() may reconfigure controller-wide settings,
which can interfere with concurrent transfers to other devices
sharing the same SPI controller but using different chip selects.

Wrap the ->dirmap_create() callback with spi_mem_access_start() and
spi_mem_access_end() to serialize access and prevent cross-CS
interference during dirmap creation.

This patch has been verified on a setup where a SPI TPM is connected
to CS0 of a SPI controller, while a SPI NOR flash is connected to CS1
of the same controller. Without this patch, spi_mem_dirmap_create()
for the SPI NOR flash interferes with ongoing SPI TPM data transfers,
resulting in failure to create the TPM device. This was tested on an
ASPEED AST2700 EVB.

The rkisp1_flt_config() function performs an initial direct write to
RKISP1_CIF_ISP_FILT_MODE without including the RKISP1_CIF_ISP_FLT_ENA

The subsequent read/modify/write sequence then reads back the register
with the enable bit already cleared and cannot restore it, resulting in
the filter being inadvertently disabled.

Remove the redundant direct write. The read/modify/write sequence alone
correctly preserves the existing enable bit state while updating the
DNR mode and filter configuration bits.

a205740a72 drm/atmel-hlcdc: fix use-after-free of drm_crtc_commit after release
[ Upstream commit bc84778723 ]

The atmel_hlcdc_plane_atomic_duplicate_state() callback was copying
the atmel_hlcdc_plane state structure without properly duplicating the
drm_plane_state. In particular, state->commit remained set to the old
state commit, which can lead to a use-after-free in the next
drm_atomic_commit() call.

Fix this by calling
__drm_atomic_helper_duplicate_plane_state(), which correctly clones
the base drm_plane_state (including the ->commit pointer).

It has been seen when closing and re-opening the device node while
another DRM client (e.g. fbdev) is still attached:

cc18db0860 drm/atmel-hlcdc: don't reject the commit if the src rect has fractional parts
[ Upstream commit 06682206e2 ]

Don’t reject the commit when the source rectangle has fractional parts.
This can occur due to scaling: drm_atomic_helper_check_plane_state() calls
drm_rect_clip_scaled(), which may introduce fractional parts while
computing the clipped source rectangle. This does not imply the commit is
invalid, so we should accept it instead of discarding it.

fe3cf809c1 drm/amd/display: Disable FEC when powering down encoders
[ Upstream commit 8cee62904c ]

[why & how]
VBIOS DMCUB FW can enable FEC for capable eDPs, but S/W DC state is
only updated for link0 when transitioning into OS with driver loaded.
This causes issues when the eDP is immediately hidden and DIG0 is
assigned to another link that does not support FEC. Driver will
attempt to disable FEC but FEC enablement occurs based on the link
state, which does not have fec_state updated since it is a different
link. Thus, FEC disablement on DIG0 will get skipped and cause no
light up.

8e1664b9ee drm: Account property blob allocations to memcg
[ Upstream commit 26b4309a3a ]

DRM_IOCTL_MODE_CREATEPROPBLOB allows userspace to allocate arbitrary-sized
property blobs backed by kernel memory.

Currently, the blob data allocation is not accounted to the allocating
process's memory cgroup, allowing unprivileged users to trigger unbounded
kernel memory consumption and potentially cause system-wide OOM.

Mark the property blob data allocation with GFP_KERNEL_ACCOUNT so that the memory
is properly charged to the caller's memcg. This ensures existing cgroup
memory limits apply and prevents uncontrolled kernel memory growth without
introducing additional policy or per-file limits.
