The built-in mic of ASUS VivoBook X513EA is broken recently by the
fix of the pin sort. The fixup ALC256_FIXUP_ASUS_MIC_NO_PRESENCE
is working for addressing the regression, too.

Pull powerpc fixes from Madhavan Srinivasan:
- a couple of fixes for out of bounds issues in memtrace and vas
Thanks to Ritesh Harjani (IBM), Haren Myneni, and Jonathan Greental
* tag 'powerpc-6.16-2' of git://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux:
powerpc/vas: Return -EINVAL if the offset is non-zero in mmap()
powerpc/powernv/memtrace: Fix out of bounds issue in memtrace mmap
|
|
The user space calls mmap() to map VAS window paste address
and the kernel returns the complete mapped page for each
window. So return -EINVAL if non-zero is passed for offset
parameter to mmap().
See Documentation/arch/powerpc/vas-api.rst for mmap()
restrictions.

The RTW_WCPU_11AC and RTW_WCPU_11N enums are used to identify two
types of microcontrollers used in Realtek chips, but these names are
misleading. The "11AC" type was also used in 11n devices (e.g.
RTL8733BU, not supported by rtw88), and the "11N" type was also used
in 11ac devices (RTL8821AU, RTL8812AU).
Rename RTW_WCPU_11AC to RTW_WCPU_3081 and RTW_WCPU_11N to RTW_WCPU_8051.
(8051 is well known. It's less clear what 3081 is, but the out of tree
drivers use this name.)

When a host is configured with a few LUNs and I/O is running, injecting
FC faults repeatedly leads to path recovery problems. The LUNs have 4
paths each and 3 of them come back active after say an FC fault which
makes 2 of the paths go down, instead of all 4. This happens after
several iterations of continuous FC faults.
Reason here is that we're returning an I/O error whenever we're
encountering sense code 06/04/0a (LOGICAL UNIT NOT ACCESSIBLE, ASYMMETRIC
ACCESS STATE TRANSITION) instead of retrying.

Currently storvsc_timeout is only used in storvsc_sdev_configure(), and
5s and 10s are used elsewhere. It turns out that rarely the 5s is not
enough on Azure, so let's use storvsc_timeout everywhere.
In case a timeout happens and storvsc_channel_init() returns an error,
close the VMBus channel so that any host-to-guest messages in the
channel's ringbuffer, which might come late, can be safely ignored.
Add a "const" to storvsc_timeout.

Previously, default chandef is configured if no chanctx is active, i.e. no
chanctx is assigned to some vif. For normal cases, it's fine. However, for
impending CSA support, need to consider that one chanctx may be added, or
called registered, ahead without being assigned immediately. Then, it will
keep inactive, and might be covered by the default one when re-calculating
chanctxs happens in certain sequences. So now, don't re-config the default
chandef unless no chanctx is registered.

The "link_id" value comes from the user via debugfs. If it's larger
than BITS_PER_LONG then that would result in shift wrapping and
potentially an out of bounds access later. In fact, we can limit it

Fortunately, only root can write to debugfs files so the security
impact is minimal.

SFQ has an assumption of always being able to queue at least one packet.
However, after the blamed commit, sch->q.len can be inflated by packets

based on where and when the kernel was built as the full path is
captured.
Since all of the files that this tool is run on is under the drivers

Calling this packet is necessary when we switch contexts because there
are various pieces of state used by userspace to synchronize between BR
and BV that are persistent across submits and we need to make sure that
they are in a "safe" state when switching contexts. Otherwise a
userspace submission in one context could cause another context to
function incorrectly and hang, effectively a denial of service (although
without leaking data). This was missed during initial a7xx bringup.

Improve the usability of the unit_add sysfs attribute by ensuring that
the associated FCP LUN scan processing is completed synchronously. This
enables configuration tooling to consistently determine the end of the
scan process to allow for serialization of follow-on actions.
While the scan process associated with unit_add typically completes
synchronously, it is deferred to an asynchronous background process if
unit_add is used before initial remote port scanning has completed. This
occurs when unit_add is used immediately after setting the associated FCP
device online.
To ensure synchronous unit_add processing, wait for remote port scanning
to complete before initiating the FCP LUN scan.

Correct the error handling goto labels used when host lookup fails in
various flashnode-related event handlers:
- iscsi_new_flashnode()
- iscsi_del_flashnode()
- iscsi_login_flashnode()
- iscsi_logout_flashnode()
- iscsi_logout_flashnode_sid()
scsi_host_put() is not required when shost is NULL, so jumping to the
correct label avoids unnecessary operations. These functions previously
jumped to the wrong goto label (put_host), which did not match the
intended cleanup logic.
Use the correct exit labels (exit_new_fnode, exit_del_fnode, etc.) to
ensure proper error handling. Also remove the unused put_host label
under iscsi_new_flashnode() as it is no longer needed.
No functional changes beyond accurate error path correction.

When things go wrong, the GPU is capable of quickly generating millions
of faulting translation requests per second. When that happens, in the
stall-on-fault model each access will stall until it wins the race to
signal the fault and then the RESUME register is written. This slows
processing page faults to a crawl as the GPU can generate faults much
faster than the CPU can acknowledge them. It also means that all
available resources in the SMMU are saturated waiting for the stalled
transactions, so that other transactions such as transactions generated
by the GMU, which shares translation resources with the GPU, cannot
proceed. This causes a GMU watchdog timeout, which leads to a failed
reset because GX cannot collapse when there is a transaction pending and
a permanently hung GPU.
On older platforms with qcom,smmu-v2, it seems that when one transaction
is stalled subsequent faulting transactions are terminated, which avoids
this problem, but the MMU-500 follows the spec here.
To work around these problems, disable stall-on-fault as soon as we get a
page fault until a cooldown period after pagefaults stop. This allows
the GMU some guaranteed time to continue working. We only use
stall-on-fault to halt the GPU while we collect a devcoredump and we
always terminate the transaction afterward, so it's fine to miss some
subsequent page faults. We also keep it disabled so long as the current
devcoredump hasn't been deleted, because in that case we likely won't
capture another one if there's a fault.
After this commit HFI messages still occasionally time out, because the
crashdump handler doesn't run fast enough to let the GMU resume, but the
driver seems to recover from it. This will probably go away after the
HFI timeout is increased.

called. Since drm_sched_job_cleanup() will NULL out the

-Wflex-array-member-not-at-end was introduced in GCC-14, and we are
getting ready to enable it, globally.
Use the `DEFINE_RAW_FLEX()` helper for on-stack definitions of
a flexible structure where the size of the flexible-array member
is known at compile-time, and refactor the rest of the code,
accordingly.
So, with these changes, fix the following warnings:
drivers/net/wireless/intel/iwlwifi/mvm/d3.c:124:52: warning: structure containing a flexible array member is not at the end of another structure [-Wflex-array-member-not-at-end]

Merge series from Félix Piédallu <felix.piedallu@non.se.com>:
These patches fix the behaviour of the SPI Chip Select of the OMAP2 MCSPI
driver used on TI SoCs.
The omap2-mcspi driver supports the use of multi mode (multichannel in TI
documentation). In this mode, the CS is asserted and deasserted by the
hardware.
The multi mode is disabled for messages when cs_change=0 for all transfers
(e.g when CS is kept asserted between transfers of a same message).
The multi mode also needs to be disabled for messages when cs_change=1 on the
last transfer (e.g when CS is kept asserted after the WHOLE message), and the
message right after.
Currently, that is not the case and it CS is deasserted by hardware when it
shouldn't.
This breaks peripheral drivers that send multiple messages with the CS asserted
in between.
Patch 1 ensures that multi mode is disabled when cs_change=1 on the last
transfer of the message.
Patch 2 ensures that multi mode is disable on a message following one with
cs_change=1 on the last transfer.
This is the case for the TPM TIS SPI driver that uses this logic for flow
control purposes.
Tested on an AM6442 platform with a TPM ST33HTPH2X32AHE4.

Commit bd7c00605ee0 ("net: move aRFS rmap management and CPU affinity
to core") allows the drivers to delegate the IRQ affinity to the NAPI
instance. However, the driver needs to use a persistent NAPI config
and explicitly set/unset the NAPI<->IRQ association.
Convert to the new IRQ affinity API.

The "ice" driver implementation uses the control VSI to handle
the flow director configuration for PFs and VFs.
Unfortunately, although a separate VSI type was created to handle flow
director queues, the Rx queue handler was shared between the flow
director and a standard NAPI Rx handler.
Such a design approach was not very flexible. First, it mixed hotpath
and slowpath code, blocking their further optimization. It also created
a huge overkill for the flow director command processing, which is
descriptor-based only, so there is no need to allocate Rx data buffers.
For the above reasons, implement a separate Rx handler for the control
VSI. Also, remove from the NAPI handler the code dedicated to
configuring the flow director rules on VFs.
Do not allocate Rx data buffers to the flow director queues because
their processing is descriptor-based only.
Finally, allow Rx data queues to be allocated only for VSIs that have
netdev assigned to them.
This handler splitting approach is the first step in converting the
driver to use the Page Pool (which can only be used for data queues).
Test hints:
1. Create a VF for any PF managed by the ice driver.
2. In a loop, add and delete flow director rules for the VF, e.g.:
for i in {1..128}; do
q=$(( i % 16 ))
ethtool -N ens802f0v0 flow-type tcp4 dst-port "$i" action "$q"
done
for i in {0..127}; do
ethtool -N ens802f0v0 delete "$i"
done
