[ Upstream commit 79efebae4afc2221fa814c3cae001bede66ab259 ]
In the spirit of [1], avoid creating multiple slab caches with the same
name. Instead, add the dev_name into the mix.

[ Upstream commit a41b3828ec056a631ad22413d4560017fed5c3bd ]
This test was added because of a bug in verifier.c:sync_linked_regs(),
upon range propagation it destroyed subreg_def marks for registers.
The test is written in a way to return an upper half of a register
that is affected by range propagation and must have it's subreg_def
preserved. This gives a return value of 0 and leads to undefined
return value if subreg_def mark is not preserved.

From: Nilay Shroff <nilay@linux.ibm.com>
[ Upstream commit e38dad438fc08162e20c600ae899e9e60688f72e ]
When nvme passthru is configured using loop target, the clear_ids
attribute is, by default, set to true. This attribute would ensure that
EUID/NGUID/UUID is cleared for the loop passthru target.
The newer NVMe disk supporting the NVMe spec 1.3 or higher, typically,
implements the support for "Namespace Identification Descriptor list"
command. This command when issued from host returns EUID/NGUID/UUID
assigned to the inquired namespace. Not clearing these values, while
using nvme passthru using loop target, would result in NVMe host driver
rejecting the namespace. This check was implemented in the commit
2079f41ec6ff ("nvme: check that EUI/GUID/UUID are globally unique").
The fix implemented in this commit ensure that when host issues ns-id
descriptor list command, the EUID/NGUID/UUID are cleared by passthru
target. In fact, the function nvmet_passthru_override_id_descs() which
clears those unique ids already exits, so we just need to ensure that
ns-id descriptor list command falls through the corretc code path. And
while we're at it, we also combines the three passthru admin command
cases together which shares the same code.

[ Upstream commit 9e9c4666abb5bb444dac37e2d7eb5250c8d52a45 ]
Controllers, supported by this driver, have two sets of registers:
* (main) interrupt registers control peripheral interrupt sources.
* device interrupt registers configure per-device (network interface)
interrupts and act as an extra stage before the main interrupt
registers.
In the driver unmask code, device trigger registers are used in the mask
calculation of the main interrupt sticky register, mixing two kinds of
registers.
Use the main interrupt trigger register instead.

The WARN is observed when the blktests test case nvme/014 is repeated
with tcp transport. It is rare, and 200 times repeat is required to
recreate in some test environments.
To avoid the WARN, check the NVME_TCP_Q_LIVE flag before locking
queue->queue_lock. The flag is cleared long time before the lock gets
destroyed.

[ Upstream commit b402328a24ee7193a8ab84277c0c90ae16768126 ]
elevator_get_default() and elv_support_iosched() both check for whether
or not q->tag_set is non-NULL, however it's not possible for them to be
NULL. This messes up some static checkers, as the checking of tag_set
isn't consistent.
Remove the checks, which both simplifies the logic and avoids checker
errors.

By default the track point does not work on the Asus Expertbook B2402FVA.
From libinput record i got the ID of the track point device:
evdev:
# Name: ASUE1201:00 04F3:32AE
# ID: bus 0x18 vendor 0x4f3 product 0x32ae version 0x100
I found that the track point is functional, when i set the
MT_CLS_WIN_8_FORCE_MULTI_INPUT_NSMU class for the reported device.

[ Upstream commit 7a5ab8071114344f62a8b1e64ed3452a77257d76 ]
The behavior of HONOR MagicBook Art 14 touchpad is not consistent
after reboots, as sometimes it reports itself as a touchpad, and
sometimes as a mouse.
Similarly to GLO-GXXX it is possible to call MT_QUIRK_FORCE_GET_FEATURE as a
workaround to force set feature in mt_set_input_mode() for such special touchpad
device.

CPRE workarounds are implicated in at least 5 MMU-500 errata, some of
which remain unfixed. The comment and warning message have proven to be
unhelpfully misleading about this scope, so reword them to get the point
across with less risk of going out of date or confusing users.

[ Upstream commit 434247637c66e1be2bc71a9987d4c3f0d8672387 ]
The kzmalloc call in bpf_check can fail when memory is very fragmented,
which in turn can lead to an OOM kill.
Use kvzmalloc to fall back to vmalloc when memory is too fragmented to
allocate an order 3 sized bpf verifier environment.
Admittedly this is not a very common case, and only happens on systems
where memory has already been squeezed close to the limit, but this does
not seem like much of a hot path, and it's a simple enough fix.

[ Upstream commit b81e286ba154a4e0f01a94d99179a97f4ba3e396 ]
As algorithm testing is carried out without holding the main crypto
lock, it is always possible for the algorithm to go away during the
test.
So before crypto_alg_tested updates the status of the tested alg,
it checks whether it's still on the list of all algorithms. This
is inaccurate because it may be off the main list but still on the
list of algorithms to be removed.
Updating the algorithm status is safe per se as the larval still
holds a reference to it. However, killing spawns of other algorithms
that are of lower priority is clearly a deficiency as it adds
unnecessary churn.
Fix the test by checking whether the algorithm is dead.

From: Harald Freudenberger <freude@linux.ibm.com>
[ Upstream commit 78f636e82b2288462498e235dc5a886426ce5dd7 ]
A crypto card comes in 3 flavors: accelerator, CCA co-processor or
EP11 co-processor. Within a protected execution environment only the
accelerator and EP11 co-processor is supported. However, it is
possible to set up a KVM guest with a CCA card and run it as a
protected execution guest. There is nothing at the host side which
prevents this. Within such a guest, a CCA card is shown as "illicit"
and you can't do anything with such a crypto card.
Regardless of the unsupported CCA card within a protected execution
guest there are a couple of user space applications which
unconditional try to run crypto requests to the zcrypt device
driver. There was a bug within the AP bus code which allowed such a
request to be forwarded to a CCA card where it is finally
rejected and the driver reacts with -ENODEV but also triggers an AP
bus scan. Together with a retry loop this caused some kind of "hang"
of the KVM guest. On startup it caused timeouts and finally led the
KVM guest startup fail. Fix that by closing the gap and make sure a
CCA card is not usable within a protected execution environment.
Another behavior within an protected execution environment with CCA
cards was that the se_bind and se_associate AP queue sysfs attributes
where shown. The implementation unconditional always added these
attributes. Fix that by checking if the card mode is supported within
a protected execution environment and only if valid, add the attribute
group.

When building for the UM arch and neither INDIRECT_IOMEM=y, nor
HAS_IOMEM=y is selected, it will fall back to the implementations from
asm-generic/io.h for IO memcpy. But these fall-back functions just do a
memcpy. So, instead of depending on UML, add dependency on 'HAS_IOMEM ||
INDIRECT_IOMEM'.

[ Upstream commit b836cbdf3b81a4a22b3452186efa2e5105a77e10 ]
Add assertions in `bpf_link_info.uprobe_multi` test to verify that
`count` and `path_size` fields are correctly populated when the fields
are unset.
This tests a previous bug where the `path_size` field was not populated
when `path` and `path_size` were unset.

[ Upstream commit 4e1e3dd88a4cedd5ccc1a3fc3d71e03b70a7a791 ]
While running ISER over SIW, the initiator machine encounters a warning
from skb_splice_from_iter() indicating that a slab page is being used in
send_page. To address this, it is better to add a sendpage_ok() check
within the driver itself, and if it returns 0, then MSG_SPLICE_PAGES flag
should be disabled before entering the network stack.
A similar issue has been discussed for NVMe in this thread:

From: Will Deacon <will@kernel.org>
[ Upstream commit 7aed6a2c51ffc97a126e0ea0c270fab7af97ae18 ]
Syzbot reports a KASAN failure early during boot on arm64 when building
with GCC 12.2.0 and using the Software Tag-Based KASAN mode:
| BUG: KASAN: invalid-access in smp_build_mpidr_hash arch/arm64/kernel/setup.c:133 [inline]
| BUG: KASAN: invalid-access in setup_arch+0x984/0xd60 arch/arm64/kernel/setup.c:356
| Write of size 4 at addr 03ff800086867e00 by task swapper/0
| Pointer tag: [03], memory tag: [fe]
Initial triage indicates that the report is a false positive and a
thorough investigation of the crash by Mark Rutland revealed the root
cause to be a bug in GCC:
> When GCC is passed `-fsanitize=hwaddress` or
> `-fsanitize=kernel-hwaddress` it ignores
> `__attribute__((no_sanitize_address))`, and instruments functions
> we require are not instrumented.
>
> [...]
>
> All versions [of GCC] I tried were broken, from 11.3.0 to 14.2.0
> inclusive.
>
> I think we have to disable KASAN_SW_TAGS with GCC until this is
> fixed
Disable Software Tag-Based KASAN when building with GCC by making
CC_HAS_KASAN_SW_TAGS depend on !CC_IS_GCC.

[ Upstream commit 1f021341eef41e77a633186e9be5223de2ce5d48 ]
We need to suppress the partition scan from occuring within the
controller's scan_work context. If a path error occurs here, the IO will
wait until a path becomes available or all paths are torn down, but that
action also occurs within scan_work, so it would deadlock. Defer the
partion scan to a different context that does not block scan_work.

Process device data pdd->vram_usage is read by rocm-smi via sysfs, this
is currently missing the svm_bo usage accounting, so "rocm-smi
--showpids" per process VRAM usage report is incorrect.
Add pdd->vram_usage accounting when svm_bo allocation and release,
change to atomic64_t type because it is updated outside process mutex
now.

In opal_event_init() if request_irq() fails name is not freed, leading
to a memory leak. The code only runs at boot time, there's no way for a
user to trigger it, so there's no security impact.
Fix the leak by freeing name in the error path.

[ Upstream commit 477d665e9b6a1369968383f50c688d56b692a155 ]
Starting with Xe2 the timestamp is a full 64 bit counter, contrary to
the 36 bit that was available before. Although 36 should be sufficient
for any reasonable delta calculation (for Xe2, of about 30min), it's
surprising to userspace to get something truncated. Also if the
timestamp being compared to is coming from the GPU and the application
is not careful enough to apply the width there, a delta calculation
would be wrong.
Extend it to full 64-bits starting with Xe2.
v2: Expand width=64 to media gt, as it's just a wrong tagging in the
spec - empirical tests show it goes beyond 36 bits and match the engines
for the main gt
Bspec: 60411

[ Upstream commit c199fac88fe7c749f88a0653e9f621b9f5a71cf1 ]
While shutting down loop controller, we first quiesce the admin/IO queue,
delete the admin/IO tag-set and then at last destroy the admin/IO queue.
However it's quite possible that during the window between quiescing and
destroying of the admin/IO queue, some admin/IO request might sneak in
and if that happens then we could potentially encounter a hung task
because shutdown operation can't forward progress until any pending I/O
is flushed off.
This commit helps ensure that before destroying the admin/IO queue, we
unquiesce the admin/IO queue so that any outstanding requests, which are
added after the admin/IO queue is quiesced, are now flushed to its
completion.

[ Upstream commit d06923670b5a5f609603d4a9fee4dec02d38de9c ]
The nvme keep-alive operation, which executes at a periodic interval,
could potentially sneak in while shutting down a fabric controller.
This may lead to a race between the fabric controller admin queue
destroy code path (invoked while shutting down controller) and hw/hctx
queue dispatcher called from the nvme keep-alive async request queuing
operation. This race could lead to the kernel crash shown below:
Call Trace:
autoremove_wake_function+0x0/0xbc (unreliable)
__blk_mq_sched_dispatch_requests+0x114/0x24c
blk_mq_sched_dispatch_requests+0x44/0x84
blk_mq_run_hw_queue+0x140/0x220
nvme_keep_alive_work+0xc8/0x19c [nvme_core]
process_one_work+0x200/0x4e0
worker_thread+0x340/0x504
kthread+0x138/0x140
start_kernel_thread+0x14/0x18
While shutting down fabric controller, if nvme keep-alive request sneaks
in then it would be flushed off. The nvme_keep_alive_end_io function is
then invoked to handle the end of the keep-alive operation which
decrements the admin->q_usage_counter and assuming this is the last/only
request in the admin queue then the admin->q_usage_counter becomes zero.
If that happens then blk-mq destroy queue operation (blk_mq_destroy_
queue()) which could be potentially running simultaneously on another
cpu (as this is the controller shutdown code path) would forward
progress and deletes the admin queue. So, now from this point onward
we are not supposed to access the admin queue resources. However the
issue here's that the nvme keep-alive thread running hw/hctx queue
dispatch operation hasn't yet finished its work and so it could still
potentially access the admin queue resource while the admin queue had
been already deleted and that causes the above crash.
This fix helps avoid the observed crash by implementing keep-alive as a
synchronous operation so that we decrement admin->q_usage_counter only
after keep-alive command finished its execution and returns the command
status back up to its caller (blk_execute_rq()). This would ensure that
fabric shutdown code path doesn't destroy the fabric admin queue until
keep-alive request finished execution and also keep-alive thread is not
running hw/hctx queue dispatch operation.
