2020-04-24scsi: qla2xxx: Delete all sessions before unregister local nvme portQuinn Tran
Delete all sessions before unregistering local nvme port. This allows nvme layer to decrement all active rport count down to zero. Once the count is down to zero, nvme would call qla to continue with the npiv port deletion.

2020-04-24scsi: qla2xxx: Fix hang when issuing nvme disconnect-all in NPIVArun Easi
In NPIV environment, a NPIV host may use a queue pair created by base host or other NPIVs, so the check for a queue pair created by this NPIV is not correct, and can cause an abort to fail, which in turn means the NVME command not returned. This leads to hang in nvme_fc layer in nvme_fc_delete_association() which waits for all I/Os to be returned, which is seen as hang in the application.

2020-04-21scsi: qla2xxx: check UNLOADING before posting async workMartin Wilck
qlt_free_session_done() tries to post async PRLO / LOGO, and waits for the completion of these async commands. If UNLOADING is set, this is doomed to timeout, because the async logout command will never complete. The only way to avoid waiting pointlessly is to fail posting these commands in the first place if the driver is in UNLOADING state. In general, posting any command should be avoided when the driver is UNLOADING. With this patch, "rmmod qla2xxx" completes without noticeable delay.

2020-04-21scsi: qla2xxx: set UNLOADING before waiting for session deletionMartin Wilck
The purpose of the UNLOADING flag is to avoid port login procedures to continue when a controller is in the process of shutting down. It makes sense to set this flag before starting session teardown. Furthermore, use atomic test_and_set_bit() to avoid the shutdown being run multiple times in parallel. In qla2x00_disable_board_on_pci_error(), the test for UNLOADING is postponed until after the check for an already disabled PCI board.

2020-04-04nvme-fc: Revert "add module to ops template to allow module references"James Smart
The original patch was to resolve the lldd being able to be unloaded while being used to talk to the boot device of the system. However, the end result of the original patch is that any driver unload while a nvme controller is live via the lldd is now being prohibited. Given the module reference, the module teardown routine can't be called, thus there's no way, other than manual actions to terminate the controllers.

2020-02-28scsi: qla2xxx: Update BPM enablement semantics.Andrew Vasquez
commit e4e3a2ce9556 ("scsi: qla2xxx: Add ability to autodetect SFP type") takes a heavy handed approach to BPM (Buffer Plus Management) enablement: 1) During hardware initialization, if an LR-capable transceiver is recognized, the driver schedules a disruptive post-initialization chip-reset (ISP-ABORT) to allow the BPM settings to be sent to the firmware. This chip-reset will result in (short-term) path-loss to all fc-rports and their attached SCSI devices. 2) LR-detection is triggered during any link-up event, resulting in a refresh and potential chip-reset Based on firmware-team guidance, upon LR-capable transceiver recognition, the driver's hardware initialization code will now re-execute firmware with the new BPM settings, then continue on with driver initialization. To address the second issue, the driver performs LR-capable detection upon the driver receiving a transceiver-insertion asynchronous event from firmware. No short-term path loss is needed with this new semantic.

2020-02-28scsi: qla2xxx: Suppress endianness complaints in qla2x00_configure_local_loop()Bart Van Assche
Instead of changing endianness in-place, write the data in CPU endian format in another buffer and copy that buffer back. This patch does not change any functionality but silences some sparse endianness warnings.

2020-02-28scsi: qla2xxx: Simplify the code for aborting SCSI commandsBart Van Assche
Since the SCSI core does not reuse the tag of the SCSI command that is being aborted by .eh_abort() before .eh_abort() has finished it is not necessary to check from inside that callback whether or not the SCSI command has already completed. Instead, rely on the firmware to return an error code when attempting to abort a command that has already completed. Additionally, rely on the firmware to return an error code when attempting to abort an already aborted command. In qla2x00_abort_srb(), use blk_mq_request_started() instead of sp->completed and sp->aborted.
