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.

Authentication application may be running and in the past tried to probe
driver (app_start) but was unsuccessful. This could be due to the bsg layer
not being ready to service the request. On a successful link up, driver
will use the netlink Link Up event to notify the app to retry the app_start

In another case, app does not poll for new NPIV host. This link up event

Commit 1f02beff224e ("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 ea7e586bdd331 ("iio: st_sensors: move regulator retrieveal
to core") only the ST pressure driver seems to have had any regulator
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.

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.

Function br_get_link_af_size_filtered() calls br_cfm_{,peer}_mep_count()
that return a count. When BRIDGE_CFM is not enabled these functions
simply return -EOPNOTSUPP but do not modify count parameter and
calling function then works with uninitialized variables.
Modify these inline functions to return zero in count parameter.

mvneta does not support asymetric pause modes, and it flags this by the
lack of AsymPause in the supported field. When setting pause modes, we
check that pause->rx_pause == pause->tx_pause, but only when pause
autoneg is enabled. When pause autoneg is disabled, we still allow
pause->rx_pause != pause->tx_pause, which is incorrect when the MAC
does not support asymetric pause, and causes mvneta to issue a warning.
Fix this by removing the test for pause->autoneg, so we always check
that pause->rx_pause == pause->tx_pause for network devices that do not
support AsymPause.

Packetization Layer itself header, namely sctphdr, whereas sctphdr
is counted by __sctp_mtu_payload().
The incorrect calculation caused the link pathmtu to be set larger

is to fix it by subtracting sctphdr len in sctp_transport_pl_hlen().

[ Upstream commit 40171248bb8934537fec8fbaf718e57c8add187c ]
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.

We use designated initializer to set fds to -1 without breaking on

The particular close(0) occurs on non-reuseport tests, so it can be seen

The firmware is offering features such as ARP offload, for which
firmware crafts its own (QoS)packets without waking up the host.
Point is that the sequence numbers generated by the firmware are
not in sync with the host mac80211 layer and can cause packets
such as firmware ARP reponses to be dropped by the AP (too old SN).
To fix this we need to let the firmware manages the sequence
numbers by its own (except for QoS null frames). There is a SN
counter for each QoS queue and one global/baseline counter for
Non-QoS.

This is essentially exactly following the dma_wmb()/dma_rmb() usage
instructions in Documentation/memory-barriers.txt.
The theoretical races here are:
1. DXE (the DMA Transfer Engine in the Wi-Fi subsystem) seeing the
dxe->ctrl & WCN36xx_DXE_CTRL_VLD write before the dxe->dst_addr_l
write, thus performing DMA into the wrong address.
2. CPU reading dxe->dst_addr_l before DXE unsets dxe->ctrl &
WCN36xx_DXE_CTRL_VLD. This should generally be harmless since DXE
doesn't write dxe->dst_addr_l (no risk of freeing the wrong skb).
