Pull SCSI updates from James Bottomley: "Updates to the usual drivers (ufs, lpfc, hisi_sas, st).

scsi: lpfc: Change lpfc_nodelist nlp_flag member into a bitmask

2024-11-03T01:45:24+00:00

In attempt to reduce the amount of unnecessary ndlp->lock acquisitions in the lpfc driver, change nlpa_flag into an unsigned long bitmask and use clear_bit/test_bit bitwise atomic APIs instead of reliance on ndlp->lock for synchronization.

scsi: lpfc: Remove NLP_RELEASE_RPI flag from nodelist structure

2024-11-03T01:45:24+00:00

An RPI is tightly bound to an NDLP structure and is freed only upon release of an NDLP object. As such, there should be no logic that frees an RPI outside of the lpfc_nlp_release() routine. In order to reinforce the original design usage of RPIs, remove the NLP_RELEASE_RPI flag and related logic.

scsi: lpfc: Prevent NDLP reference count underflow in dev_loss_tmo callback

2024-11-03T01:45:24+00:00

Current dev_loss_tmo handling checks whether there has been a previous call to unregister with SCSI transport. If so, the NDLP kref count is decremented a second time in dev_loss_tmo as the final kref release. However, this can sometimes result in a reference count underflow if there is also a race to unregister with NVMe transport as well. Add a check for NVMe transport registration before decrementing the final kref. If NVMe transport is still registered, then the NVMe transport unregistration is designated as the final kref decrement.

scsi: lpfc: Add cleanup of nvmels_wq after HBA reset

2024-11-03T01:45:24+00:00

An HBA reset request that is executed when there are outstanding NVME-LS commands can cause delays for the reset process to complete. Fix by introducing a new routine called lpfc_nvmels_flush_cmd() that walks the phba->nvmels_wq list and cancels outstanding submitted NVME-LS requests speeding up the HBA reset process.

scsi: lpfc: Check SLI_ACTIVE flag in FDMI cmpl before submitting follow up FDMI

2024-11-03T01:45:24+00:00

The lpfc_cmpl_ct_disc_fdmi() routine has incorrect logic that treats an FDMI completion with error LOCAL_REJECT/SLI_ABORTED as a success status. Under the erroneous assumption of successful completion, the routine proceeds to issue follow up FDMI commands, which may never complete if the HBA is in an errata state as indicated by the errored completion status. Fix by freeing FDMI cmd resources and early return when the LPFC_SLI_ACTIVE flag is not set and a LOCAL_REJECT/SLI_ABORTED or SLI_DOWN status is received.
