ac9b57d4e1 nvme-pci: disable write zeroes on various Kingston SSD
Kingston SSDs do support NVMe Write_Zeroes cmd but take long time to
process.  The firmware version is locked by these SSDs, we can not expect
firmware improvement, so disable Write_Zeroes cmd.

4739824e2d nvme: fix error pointer dereference in error handling
There is typo here so it releases the wrong variable.  "ctrl->admin_q"
was intended instead of "ctrl->fabrics_q".

96df8360db netfilter: nf_tables: relax NFTA_SET_ELEM_KEY_END set flags requirements
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.

1fcc064b30 netfilter: rpfilter/fib: Set ->flowic_uid correctly for user namespaces.
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.

aa1d7e1267 ionic: catch NULL pointer issue on reconfig
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.

syzbot got a crash [1] in skb_clone(), caused by a bug

e688ba3e27 drm/amdkfd: Fix type of reset_type parameter in hqd_destroy() callback
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.

8a70b2d89e drm/amd/display: Increase frame size limit for display_mode_vba_util_32.o
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

32-bit build tests with affected compilers.

afd41fff9c dm verity: enable WQ_HIGHPRI on verify_wq
WQ_HIGHPRI increases throughput and decreases disk latency when using
dm-verity. This is important in Android for camera startup speed.

The following tests were run by doing 60 seconds of random reads using
a dm-verity device backed by two ramdisks.

Without WQ_HIGHPRI
lat (usec): min=13, max=3947, avg=69.53, stdev=50.55
READ: bw=51.1MiB/s (53.6MB/s), 51.1MiB/s-51.1MiB/s (53.6MB/s-53.6MB/s)

With WQ_HIGHPRI:
lat (usec): min=13, max=7854, avg=31.15, stdev=30.42
READ: bw=116MiB/s (121MB/s), 116MiB/s-116MiB/s (121MB/s-121MB/s)

Further testing was done by measuring how long it takes to open a
camera on an Android device.

Without WQ_HIGHPRI
Total verity work queue wait times (ms):
880.960, 789.517, 898.852

With WQ_HIGHPRI:
Total verity work queue wait times (ms):
528.824, 439.191, 433.300

The average time to open the camera is reduced by 350ms (or 40-50%).

67bf649344 x86/resctrl: Fix min_cbm_bits for AMD
AMD systems support zero CBM (capacity bit mask) for cache allocation.
That is reflected in rdt_init_res_defs_amd() by:

  r->cache.arch_has_empty_bitmaps = true;

However given the unified code in cbm_validate(), checking for:

  val == 0 && !arch_has_empty_bitmaps

is not enough because of another check in cbm_validate():

  if ((zero_bit - first_bit) < r->cache.min_cbm_bits)

The default value of r->cache.min_cbm_bits = 1.

Leading to:

  $ cd /sys/fs/resctrl
  $ mkdir foo
  $ cd foo
  $ echo L3:0=0 > schemata
    -bash: echo: write error: Invalid argument
  $ cat /sys/fs/resctrl/info/last_cmd_status
    Need at least 1 bits in the mask

Initialize the min_cbm_bits to 0 for AMD. Also, remove the default
setting of min_cbm_bits and initialize it separately.

After the fix:

  $ cd /sys/fs/resctrl
  $ mkdir foo
  $ cd foo
  $ echo L3:0=0 > schemata
  $ cat /sys/fs/resctrl/info/last_cmd_status
    ok

141b3523e9 dm bufio: use the acquire memory barrier when testing for B_READING
The function test_bit doesn't provide any memory barrier. It may be
possible that the read requests that follow test_bit(B_READING, &b->state)
are reordered before the test, reading invalid data that existed before
B_READING was cleared.

Fix this bug by changing test_bit to test_bit_acquire. This is
particularly important on arches with weak(er) memory ordering
(e.g. arm64).
