commit a360f311f5 upstream.
This was attempted by using the dev_name in the slab cache name, but as
Omar Sandoval pointed out, that can be an arbitrary string, eg something
like "/dev/root". Which in turn trips verify_dirent_name(), which fails
if a filename contains a slash.
So just make it use a sequence counter, and make it an atomic_t to avoid
any possible races or locking issues.

commit 704573851b upstream.
This patch addresses an issue introduced by commit 1a83a716ec ("mm:
krealloc: consider spare memory for __GFP_ZERO") which causes MTE
(Memory Tagging Extension) to falsely report a slab-out-of-bounds error.
The problem occurs when zeroing out spare memory in __do_krealloc. The
original code only considered software-based KASAN and did not account
for MTE. It does not reset the KASAN tag before calling memset, leading
to a mismatch between the pointer tag and the memory tag, resulting
in a false positive.
Example of the error:

commit 0ce160c5bd upstream.
Syzbot has found an ODEBUG bug in ext4_fill_super
The del_timer_sync function cancels the s_err_report timer,
which reminds about filesystem errors daily. We should
guarantee the timer is no longer active before kfree(sbi).
When filesystem mounting fails, the flow goes to failed_mount3,
where an error occurs when ext4_stop_mmpd is called, causing
a read I/O failure. This triggers the ext4_handle_error function
that ultimately re-arms the timer,
leaving the s_err_report timer active before kfree(sbi) is called.
Fix the issue by canceling the s_err_report timer after calling ext4_stop_mmpd.

Move the logic of fetching temporary per-CPU uprobe buffer and storing

of this buffer, simplifying interfaces a bit, as now we only pass single

This logic was duplicated across uprobe_dispatcher and uretprobe_dispatcher,
and now will be centralized. All this is also in preparation to make

commit 73254a297c upstream.
The io_register_iowq_max_workers() function calls io_put_sq_data(),
which acquires the sqd->lock without releasing the uring_lock.
Similar to the commit 009ad9f0c6 ("io_uring: drop ctx->uring_lock
before acquiring sqd->lock"), this can lead to a potential deadlock
situation.
To resolve this issue, the uring_lock is released before calling
io_put_sq_data(), and then it is re-acquired after the function call.
This change ensures that the locks are acquired in the correct
order, preventing the possibility of a deadlock.

[ Upstream commit fb86c42a2a ]
In the bpf_out_neigh_v6 function, rcu_read_lock() is used to begin an RCU
read-side critical section. However, when unlocking, one branch
incorrectly uses a different RCU unlock flavour rcu_read_unlock_bh()
instead of rcu_read_unlock(). This mismatch in RCU locking flavours can
lead to unexpected behavior and potential concurrency issues.
This possible bug was identified using a static analysis tool developed
by myself, specifically designed to detect RCU-related issues.
This patch corrects the mismatched unlock flavour by replacing the
incorrect rcu_read_unlock_bh() with the appropriate rcu_read_unlock(),
ensuring that the RCU critical section is properly exited. This change
prevents potential synchronization issues and aligns with proper RCU
usage patterns.

[ Upstream commit d06923670b ]
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.

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.

commit f033c87fda upstream.
Starting with commit f6038de293 ("arm64: dts: imx8qm: Fix VPU core
alias name") the alias for VPU cores uses dashes instead of underscores.
Adjust the alias stem accordingly. Fixes the errors:
amphion-vpu-core 2d040000.vpu-core: can't get vpu core id
amphion-vpu-core 2d050000.vpu-core: can't get vpu core id

commit de156f3cf7 upstream.
Xiaomi Book Pro 14 2022 (MIA2210-AD) requires a quirk entry for its
internal microphone to be enabled.
This is likely due to similar reasons as seen previously on Redmi Book
14/15 Pro 2022 models (since they likely came with similar firmware):
- commit dcff8b7ca9 ("ASoC: amd: yc: Add Xiaomi Redmi Book Pro 15 2022
into DMI table")
- commit c1dd6bf619 ("ASoC: amd: yc: Add Xiaomi Redmi Book Pro 14 2022
into DMI table")
A quirk would likely be needed for Xiaomi Book Pro 15 2022 models, too.
However, I do not have such device on hand so I will leave it for now.

commit 464cb98f1c upstream.
Christoffer reports that on some implementations, writing to
GICR_ISACTIVER0 (and similar GICD registers) can race badly with a guest
issuing a deactivation of that interrupt via the system register interface.
There are multiple reasons to this:
- this uses an early write-acknoledgement memory type (nGnRE), meaning
that the write may only have made it as far as some interconnect
by the time the store is considered "done"
- the GIC itself is allowed to buffer the write until it decides to
take it into account (as long as it is in finite time)
The effects are that the activation may not have taken effect by the time
the kernel enters the guest, forcing an immediate exit, or that a guest
deactivation occurs before the interrupt is active, doing nothing.
In order to guarantee that the write to the ISACTIVER register has taken
effect, read back from it, forcing the interconnect to propagate the write,
and the GIC to process the write before returning the read.
