PORT UPDATE asynchronous event is generated on the host that issues PLOGI
ELS (in the case of higher WWPN). In that case, the event shouldn't be
handled as it sets unwanted DPC flags (i.e. LOOP_RESYNC_NEEDED) that
trigger link flap.
Ignore the event if the host has higher WWPN, but handle otherwise.

qla2x00_configure_local_loop sets RELOGIN_NEEDED bit and calls

up of DPC later after a successful login.
The deferred call is not needed if login succeeds, and it's set in
qla24xx_fcport_handle_login in case of errors, hence it should be safe to
drop.

Target makes implicit LOGO on session teardown. LOGO ELS is not send on the

it. Initiator keeps sending I/O requests, target responds with BA_RJT, they
time out and then initiator sends ABORT TASK (ABTS-LS).
Current behaviour incurs unneeded I/O timeout and can be fixed for some
initiators by making explicit LOGO on session deletion.

[ Upstream commit 863fbae929 ]
In nvme-fc: it's possible to have connected active controllers
and as no references are taken on the LLDD, the LLDD can be
unloaded. The controller would enter a reconnect state and as
long as the LLDD resumed within the reconnect timeout, the
controller would resume. But if a namespace on the controller
is the root device, allowing the driver to unload can be problematic.
To reload the driver, it may require new io to the boot device,
and as it's no longer connected we get into a catch-22 that
eventually fails, and the system locks up.
Fix this issue by taking a module reference for every connected
controller (which is what the core layer did to the transport
module). Reference is cleared when the controller is removed.

The crash can be triggered by ACL deletion when there's active I/O.
During ACL deletion, qla2xxx performs implicit LOGO that's invisible for
the initiator. Only the driver and firmware are aware of the logout.
Therefore the initiator continues to send SCSI commands and the target
always responds with SAM STATUS BUSY as it can't find the session.
The command times out after a while and initiator invokes ABORT TASK TMF
for the command. The TMF is mapped to ABTS-LS in FCP. The target can't find
session for S_ID originating ABTS-LS so it never allocates mcmd. And since
N_Port handle was deleted after LOGO, it is no longer valid and ABTS
Response IOCB is returned from firmware with status 31. Then free_mcmd is
invoked on NULL pointer and the kernel crashes.

Abort will tell FW to release the command from FW possesion. The original

This causes lockups (on powerpc) when firmware config space access calls
