Until now ack'ing of a new PLOGI has only been delayed if there was an existing session for the same WWN. Ack was released when the session deletion completed. If there was another WWN session with the same fc_id/loop_id pair (aka "conflicting session"), PLOGI was still ack'ed immediately. This potentially caused a problem when old session deletion logged fc_id/loop_id out of FW after new session has been established. Two work-arounds were attempted before: 1. Dropping PLOGIs until conflicting session goes away. 2. Detecting initiator being logged out of FW and issuing LOGO to force re-login. This patch introduces proper solution to the problem where PLOGI is held until either existing session with same WWN or any conflicting session goes away. Mechanism supports one session holding two PLOGI acks as well as one PLOGI ack being held by many sessions.

RSCN processing in qla2xxx driver can run in parallel with ELS/IO processing. As such the decision to remove disappeared fc port's session could be stale, because a new login sequence has occurred since and created a brand new session. Previous mechanism of dealing with this by delaying deletion request was prone to erroneous deletions if the event that was supposed to cancel the deletion never arrived or has been delayed in processing. New mechanism relies on a time-like generation counter to serialize RSCN updates relative to ELS/IO updates.

When deletion process completes this iocb will be acked. Only the most recent PLOGI iocb is stored. The older ones will be terminated when replaced. - new PRLI will initiate deletion of the following sessions (unless deletion is already IN_PROGRESS): - different port_name, different port_id, but the same loop_id (without logout) Cc: <stable@vger.kernel.org> # v3.18+ Signed-off-by: NAlexei Potashnik <alexei@purestorage.com> Acked-by: NQuinn Tran <quinn.tran@qlogic.com> Signed-off-by: NHimanshu Madhani <himanshu.madhani@qlogic.com> Signed-off-by: NNicholas Bellinger <nab@linux-iscsi.org>

Since cmds go into qla_tgt_wq and TMRs don't, it's possible that TMR like TASK_ABORT can be queued over the cmd for which it was meant. To avoid this race, use a per-port list to keep track of cmds that are enqueued to qla_tgt_wq but not yet processed. When a TMR arrives, iterate through this list and remove any cmds that match the TMR. This patch supports TASK_ABORT and LUN_RESET.

To fix some issues talking to ESX, this patch modifies the qla2xxx driver so that it never logs into remote ports. This has the side effect of getting rid of the "rports" entirely, which means we never log out of initiators and never tear down sessions when an initiator goes away. This is mostly OK, except that we can run into trouble if we have initiator A assigned FC address X:Y:Z by the fabric talking to us, and then initiator A goes away. Some time (could be a long time) later, initiator B comes along and also gets FC address X:Y:Z (which is available again, because initiator A is gone). If initiator B starts talking to us, then we'll still have the session for initiator A, and since we look up incoming IO based on the FC address X:Y:Z, initiator B will end up using ACLs for initiator A. Fix this by: 1. Handling RSCN events somewhat differently; instead of completely skipping the processing of fcports, we look through the list, and if an fcport disappears, we tell the target code the tear down the session and tell the HBA FW to release the N_Port handle. 2. Handling "port down" events by flushing all of our sessions. The firmware was already releasing the N_Port handle but we want the target code to drop all the sessions too.

Through the qla target code, the qlt_send_term_exchange() routine is used in various different places to cleanup an exchange. For the case of IOCB request queue is full, the exchange is left unhandled/ dangling. Existing code does not have re-try logic to cleanup the exchange. This patch add retry logic to cleanup the exchange before letting new commands through. For the case of FW running out of exchanges, driver need to reply SAM_STAT_BUSY to the initiators. This patch add a pending queue for the busy reply in case IOCB queue is unable to handle the cmd.
