scsi: lpfc: Add capability to register Platform Name ID to fabric

2025-11-08T18:18:01Z

FC-LS and FC-GS specifications outline fields for registering a platform name identifier (PNI) to the fabric. The PNI assists fabrics with identifying the physical server source of frames in the fabric. lpfc generates a PNI based partially on the uuid specific for the system. Initial attempts to extract a uuid are made from SMBIOS's System Information 08h uuid entry. If SMBIOS DMI does not exist, a PNI is not generated and PNI registration with the fabric is skipped. The PNI is submitted in FLOGI and FDISC frames. After successful fabric login, the RSPNI_PNI CT frame is submitted to the fabric to register the OS host name tying it to the PNI.

scsi: lpfc: Early return out of FDMI cmpl for locally rejected statuses

2025-06-23T17:10:33Z

If an FDMI request completes with local reject status and the request is not retryable, there's no need to parse an FDMI response payload. Insert an early return statement for such cases.

scsi: lpfc: Change lpfc_nodelist save_flags member into a bitmask

2025-01-02T20:01:22Z

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

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

2024-11-03T01:45:24Z

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.

scsi: lpfc: Revise TRACE_EVENT log flag severities from KERN_ERR to KERN_WARNING

2024-09-13T01:21:19Z

Revise certain log messages marked as KERN_ERR LOG_TRACE_EVENT to KERN_WARNING and use the lpfc_vlog_msg() macro to still log the event. The benefit is that events of interest are still logged and the entire trace buffer is not dumped with extraneous logging information when using default lpfc_log_verbose driver parameter settings. Also, delete the keyword "fail" from such log messages as they aren't really causes for concern. The log messages are more for warnings to a SAN admin about SAN activity.

scsi: lpfc: Ensure DA_ID handling completion before deleting an NPIV instance

2024-09-13T01:21:19Z

Deleting an NPIV instance requires all fabric ndlps to be released before an NPIV's resources can be torn down. Failure to release fabric ndlps beforehand opens kref imbalance race conditions. Fix by forcing the DA_ID to complete synchronously with usage of wait_queue.
