2019-11-26scsi: qla2xxx: Fix qla2x00_request_irqs() for MSIHuacai Chen1-3/+3
Commit 4fa183455988 ("scsi: qla2xxx: Utilize pci_alloc_irq_vectors/ pci_free_irq_vectors calls.") use pci_alloc_irq_vectors() to replace pci_enable_msi() but it didn't handle the return value correctly.

2019-11-26scsi: qla2xxx: unregister ports after GPN_FT failureMartin Wilck1-2/+14
When ports are lost due to unzoning them, and the initiator port is not part of any more zones, the GPN_FT command used for the fabric scan may fail. In this case, the current code simply gives up after a few retries. But if the zone is gone, all rports should actually be marked as lost. Fix this by jumping to the code that handles logout after GNN_FT after scan retries are exhausted.

2019-11-08scsi: qla2xxx: Fix double scsi_done for abort pathQuinn Tran4-59/+72
Current code assumes abort will remove the original command from the active list where scsi_done will not be called. Instead, the eh_abort thread will do the scsi_done. That is not the case. Instead, we have a double scsi_done calls triggering use after free. Abort will tell FW to release the command from FW possesion. The original command will return to ULP with error in its normal fashion via scsi_done. eh_abort path would wait for the original command completion before returning. eh_abort path will not perform the scsi_done call.

Commit 88263208dd23 ("scsi: qla2xxx: Complain if sp->done() is not called from the completion path") introduced the WARN_ON_ONCE in qla2x00_status_cont_entry(). The assumption was that there is only one status continuations element. According to the firmware documentation it is possible that multiple status continuations are emitted by the firmware.
