Whether htonl() or __constant_htonl() is used, if the argument is a constant the conversion happens at compile time. Hence leave out the __constant_ prefix for this and other endianness conversion functions. This improves source code readability.

2015-07-24qla2xxx: added sess generations to detect RSCN update racesAlexei Potashnik1-1/+1
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.

2015-07-24qla2xxx: delay plogi/prli ack until existing sessions are deletedAlexei Potashnik1-3/+3
- keep qla_tgt_sess object on the session list until it's freed - modify use of sess->deleted flag to differentiate delayed session deletion that can be cancelled from irreversible one: QLA_SESS_DELETION_PENDING vs QLA_SESS_DELETION_IN_PROGRESS - during IN_PROGRESS deletion all newly arrived commands and TMRs will be rejected, existing commands and TMRs will be terminated when given by the core to the fabric or simply dropped if session logout has already happened (logout terminates all existing exchanges) - new PLOGI will initiate deletion of the following sessions (unless deletion is already IN_PROGRESS): - with the same port_name (with logout) - different port_name, different loop_id but the same port_id (with logout) - different port_name, different port_id, but the same loop_id (without logout) - additionally each new PLOGI will store imm notify iocb in the same port_name session being deleted. 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: Alexei Potashnik <alexei@purestorage.com> Acked-by: Quinn Tran <quinn.tran@qlogic.com> Signed-off-by: Himanshu Madhani <himanshu.madhani@qlogic.com> Signed-off-by: Nicholas Bellinger <nab@linux-iscsi.org>
2015-07-24qla2xxx: cleanup cmd in qla workqueue before processing TMRSwapnil Nagle1-1/+1
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.

2015-07-24qla2xxx: kill sessions/log out initiator on RSCN and port down eventsRoland Dreier1-1/+1
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.

2014-09-25qla2xxx: Add support for QFull throttling and Term Exchange retryQuinn Tran1-2/+2
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.
