- incorrect represented Capture input selector in alsamixer

- wrong control selected as Capture Master
The "Server interfaces" count in /proc/fs/cifs/DebugData increases
as the interfaces are requeried, rather than being reset to the new
value. This could cause a problem if the server disabled

SELinux: Context system_u:object_r:pssp_rsyslog_log_t:s0:c0 is
not valid (left unmapped).
It was found that within a critical section of spin_lock_irqsave in
sidtab_context_to_sid(), convert_context() (hooked by
sidtab_convert_params.func) might cause the process to sleep via
allocating memory with GFP_KERNEL, which is problematic.
As Ondrej pointed out [1], convert_context()/sidtab_convert_params.func
has another caller sidtab_convert_tree(), which is okay with GFP_KERNEL.
Therefore, fix this problem by adding a gfp_t argument for
convert_context()/sidtab_convert_params.func and pass GFP_KERNEL/_ATOMIC
properly in individual callers.

Currently qdisc ingress handling (sch_handle_ingress()) doesn't
set a return value and it is left to the old return value of
the caller (__netif_receive_skb_core()) which is RX drop, so if
the packet is consumed, caller will stop and return this value
as if the packet was dropped.
This causes a problem in the kernel tcp stack when having a
egress tc rule forwarding to a ingress tc rule.
The tcp stack sending packets on the device having the egress rule
will see the packets as not successfully transmitted (although they
actually were), will not advance it's internal state of sent data,
and packets returning on such tcp stream will be dropped by the tcp
stack with reason ack-of-unsent-data. See reproduction in [0] below.
Fix that by setting the return value to RX success if
the packet was handled successfully.

The "convert-xxx" properties only have an effect for DPCM DAI links.
A DAI link is only created as DPCM if the device tree requires it;
part of this involves checking for the use of "convert-xxx" properties.
When the convert-sample-format property was added, the checks got out
of sync. A DAI link that specified only convert-sample-format but did
not pass any of the other DPCM checks would not go into DPCM mode and
the convert-sample-format property would be silently ignored.
Fix this by adding a function to do the "convert-xxx" property checks,
instead of open-coding it in simple-card and audio-graph-card. And add
"convert-sample-format" to the check function so that DAI links using
it will be initialized correctly.

Recent commit 52fde2c07d ("nvme: set dma alignment to dword") has
caused a regression on our platform.
It turned out that the nvme_get_log() method invocation caused the
nvme_hwmon_data structure instance corruption. In particular the
nvme_hwmon_data.ctrl pointer was overwritten either with zeros or with
garbage. After some research we discovered that the problem happened
even before the actual NVME DMA execution, but during the buffer mapping.
Since our platform is DMA-noncoherent, the mapping implied the cache-line
invalidations or write-backs depending on the DMA-direction parameter.
In case of the NVME SMART log getting the DMA was performed
from-device-to-memory, thus the cache-invalidation was activated during
the buffer mapping. Since the log-buffer isn't cache-line aligned, the
cache-invalidation caused the neighbour data to be discarded. The
neighbouring data turned to be the data surrounding the buffer in the
framework of the nvme_hwmon_data structure.
In order to fix that we need to make sure that the whole log-buffer is
defined within the cache-line-aligned memory region so the
cache-invalidation procedure wouldn't involve the adjacent data. One of
the option to guarantee that is to kmalloc the DMA-buffer [1]. Seeing the
rest of the NVME core driver prefer that method it has been chosen to fix
this problem too.
Note after a deeper researches we found out that the denoted commit wasn't
a root cause of the problem. It just revealed the invalidity by activating
the DMA-based NVME SMART log getting performed in the framework of the
NVME hwmon driver. The problem was here since the initial commit of the
driver.

Otherwise EINVAL is bogusly reported to userspace when deleting a set
element. NFTA_SET_ELEM_KEY_END does not need to be set in case of:
- insertion: if not present, start key is used as end key.
- deletion: only start key needs to be specified, end key is ignored.
Hence, relax the sanity check.

Currently netfilter's rpfilter and fib modules implicitely initialise
->flowic_uid with 0. This is normally the root UID. However, this isn't
the case in user namespaces, where user ID 0 is mapped to a different
kernel UID. By initialising ->flowic_uid with sock_net_uid(), we get
the root UID of the user namespace, thus keeping the same behaviour
whether or not we're running in a user namepspace.
Note, this is similar to commit 8bcfd0925e ("ipv4: add missing
initialization for flowi4_uid"), which fixed the rp_filter sysctl.
Fixes: 622ec2c9d5 ("net: core: add UID to flows, rules, and routes")

It's possible that the driver will dereference a qcq that doesn't exist
when calling ionic_reconfigure_queues(), which causes a page fault BUG.
If a reduction in the number of queues is followed by a different
reconfig such as changing the ring size, the driver can hit a NULL
pointer when trying to clean up non-existent queues.
Fix this by checking to make sure both the qcqs array and qcq entry
exists bofore trying to use and free the entry.

[Why]
If mes is not dequeued during fini, mes will be in an uncleaned state
during reload, then mes couldn't receive some commands which leads to
reload failure.
[How]
Perform MES dequeue via MMIO after all the unmap jobs are done by mes
and before kiq fini.
v2: Move the dequeue operation inside kiq_hw_fini.

When booting a kernel compiled with CONFIG_CFI_CLANG on a machine with
an RX 6700 XT, there is a CFI failure in kfd_destroy_mqd_cp():
[ 12.894543] CFI failure at kfd_destroy_mqd_cp+0x2a/0x40 [amdgpu] (target: hqd_destroy_v10_3+0x0/0x260 [amdgpu]; expected type: 0x8594d794)
Clang's kernel Control Flow Integrity (kCFI) makes sure that all
indirect call targets have a type that exactly matches the function
pointer prototype. In this case, hqd_destroy()'s third parameter,
reset_type, should have a type of 'uint32_t' but every implementation of
this callback has a third parameter type of 'enum kfd_preempt_type'.
Update the function pointer prototype to match reality so that there is
no more CFI violation.

Building 32-bit images may fail with the following error.
drivers/gpu/drm/amd/amdgpu/../display/dc/dml/dcn32/display_mode_vba_util_32.c:
In function ‘dml32_UseMinimumDCFCLK’:
drivers/gpu/drm/amd/amdgpu/../display/dc/dml/dcn32/display_mode_vba_util_32.c:3142:1:
error: the frame size of 1096 bytes is larger than 1024 bytes
This is seen when building i386:allmodconfig with any of the following
compilers.
gcc (Debian 12.2.0-3) 12.2.0
gcc (Ubuntu 9.4.0-1ubuntu1~20.04.1) 9.4.0
The problem is not seen if the compiler supports GCC_PLUGIN_LATENT_ENTROPY
because in that case CONFIG_FRAME_WARN is already set to 2048 even for
32-bit builds.
dml32_UseMinimumDCFCLK() was introduced with commit dda4fb85e4
("drm/amd/display: DML changes for DCN32/321"). It declares a large
number of local variables. Increase the frame size for the affected
file to 2048, similar to other files in the same directory, to enable
32-bit build tests with affected compilers.
