Currently, we hold off unregistering with NVMe transport layer until GID_FT
or ADISC completes upon receipt of RSCN. In the ADISC discovery routine,
for nodes not found in the GID_FT response, the nodes are unregistered from
the SCSI transport but not UNREG_RPI'd. Meaning outstanding WQEs continue
to be outstanding and were not failed back to the OS. If an NVMe device,
this mean there wasn't initial termination of the I/Os so they could be
issued on a different NVMe path.
Fix by unregistering the RPI so that I/O is cancelled.

Commit 1f02beff22 ("scsi: pm80xx: Remove global lock from outbound queue
processing") introduced a lock per outbound queue. Prior to that change the
driver was using a global lock for all outbound queues.
While processing the I/O responses and events the driver takes the outbound
queue spinlock and is supposed to release it in pm8001_ccb_task_free_done()
before calling command done(). Since the older code was using a global
lock, pm8001_ccb_task_free_done() was releasing the global spin lock. The
change that split the lock per outbound queue did not consider this and
pm8001_ccb_task_free_done() was still releasing the global lock.

Up until commit ea7e586bdd ("iio: st_sensors: move regulator retrieveal

disable. After that commit, the regulator handling was moved into the
common st_sensors logic.
In all instances of this regulator handling, the regulators were disabled
before unregistering the IIO device.
This can cause issues where the device would be powered down and still be
available to userspace, allowing it to send invalid/garbage data.
This change moves the st_sensors_power_disable() after the common probe
functions. These common probe functions also handle unregistering the IIO
device.

[ Upstream commit 6b278c0cb3 ]
If we get CRQ_INIT, we set errno to -EIO and first call complete() to
notify the waiter. Then we try to schedule a FAILOVER reset. If this
occurs while adapter is in PROBING state, ibmvnic_reset() changes the
error code to EAGAIN and returns without scheduling the FAILOVER. The
purpose of setting error code to EAGAIN is to ask the waiter to retry.
But due to the earlier complete() call, the waiter may already have seen
the -EIO response and decided not to retry. This can cause intermittent
failures when bringing up ibmvnic adapters during boot, specially in
in kexec/kdump kernels.
Defer the complete() call until after scheduling the reset.
Also streamline the error code to EAGAIN. Don't see why we need EIO
sometimes. All 3 callers of ibmvnic_reset_init() can handle EAGAIN.

If adapter's resetting bit is on, discard the packet but don't stop the
transmit queue - instead leave that to the reset code. With this change,
it is possible that we may get several calls to ibmvnic_xmit() that simply
discard packets and return.
But if we stop the queue here, we might end up doing so just after
__ibmvnic_open() started the queues (during a hard/soft reset) and before
the ->resetting bit was cleared. If that happens, there will be no one to
restart queue and transmissions will be blocked indefinitely.
This can cause a TIMEOUT reset and with auto priority failover enabled,
an unnecessary FAILOVER reset to less favored backing device and then a
FAILOVER back to the most favored backing device. If we hit the window
repeatedly, we can get stuck in a loop of TIMEOUT, FAILOVER, FAILOVER
resets leaving the adapter unusable for extended periods of time.

These three events can race when pcrypt is used multiple times in a
template ("pcrypt(pcrypt(...))"):
1. [taskA] The caller makes the crypto request via crypto_aead_encrypt()
2. [kworkerB] padata serializes the inner pcrypt request
3. [kworkerC] padata serializes the outer pcrypt request
3 might finish before the call to crypto_aead_encrypt() returns in 1,
resulting in two possible issues.
First, a use-after-free of the crypto request's memory when, for
example, taskA writes to the outer pcrypt request's padata->info in
pcrypt_aead_enc() after kworkerC completes the request.
Second, the outer pcrypt request overwrites the inner pcrypt request's
return code with -EINPROGRESS, making a successful request appear to
fail. For instance, kworkerB writes the outer pcrypt request's
padata->info in pcrypt_aead_done() and then taskA overwrites it
in pcrypt_aead_enc().
Avoid both situations by delaying the write of padata->info until after
the inner crypto request's return code is checked. This prevents the
use-after-free by not touching the crypto request's memory after the
next-inner crypto request is made, and stops padata->info from being
overwritten.

Currently when PLPMTUD enters Error state, transport pathmtu will be set
to MIN_PLPMTU(512) while probe is continuing with BASE_PLPMTU(1200). It
will cause pathmtu to stay in a very small value, even if the real pmtu
is some value like 1000.
RFC8899 doesn't clearly say how to set the value in Error state. But one
possibility could be keep using BASE_PLPMTU for the real pmtu, but allow
to do IP fragmentation when it's in Error state.
As it says in rfc8899#section-5.4:
Some paths could be unable to sustain packets of the BASE_PLPMTU
size. The Error State could be implemented to provide robustness to
such paths. This allows fallback to a smaller than desired PLPMTU
rather than suffer connectivity failure. This could utilize methods
such as endpoint IP fragmentation to enable the PL sender to
communicate using packets smaller than the BASE_PLPMTU.
This patch is to set pmtu to BASE_PLPMTU instead of MIN_PLPMTU for Error
state in sctp_transport_pl_send/toobig(), and set packet ipfragok for
non-probe packets when it's in Error state.

[ Upstream commit c3fc706e94 ]
Similar to the fix in commit:
e31eec77e4 ("bpf: selftests: Fix fd cleanup in get_branch_snapshot")
We use designated initializer to set fds to -1 without breaking on
future changes to MAX_SERVER constant denoting the array size.
The particular close(0) occurs on non-reuseport tests, so it can be seen
with -n 115/{2,3} but not 115/4. This can cause problems with future
tests if they depend on BTF fd never being acquired as fd 0, breaking
internal libbpf assumptions.

[ Upstream commit a5c5d8d50e ]
amdgpu_fence_driver_sw_fini() should be executed before
amdgpu_device_ip_fini(), otherwise fence driver resource
won't be properly freed as adev->rings have been tore down.

[ Upstream commit d707f812bb ]
The channel scan list must be updated before triggering a hardware scan
so that firmware takes into account the regulatory info for each single
channel such as active/passive config, power, DFS, etc... Without this
the firmware uses its own internal default channel configuration, which
is not aligned with mac80211 regulatory rules, and misses several
channels (e.g. 144).
