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: Fix leaked ndlp krefs when in point-to-point topology

2025-11-08T18:18:00Z

In point-to-point topology, the driver sometimes defers the unsolicited FLOGI LS_ACC until it sends its FLOGI to the remote port. When this happens, lpfc neglects to release the ndlp allocated for the unsolicited FLOGI. This patch adds code to release the ndlp for the deferred unsolicited FLOGI LS_ACC. An NLP_FLOGI_DFR_ACC flag is introduced to facilitate identifying an ndlp with an expected deferred FLOGI LS_ACC completion. When lpfc_cmpl_els_rsp() detects the correct qualifiers, it releases the initial reference on the ndlp object. And when lpfc_cmpl_els_rsp() exits, the remaining put for the deferred action is executed and the ndlp is released.

scsi: lpfc: Convert debugfs directory counts from atomic to unsigned int

2025-09-17T02:20:00Z

Atomicity is not necessary for debugfs directory accounting because vport deletion and creation is already serialized. Creation has always been serialized through sysfs. Deletion is serialized via walking the lpfc_create_vport_work_array and calling fc_vport_terminate one-by-one for each NPIV port.

scsi: lpfc: Clean up extraneous phba dentries

2025-09-17T02:20:00Z

Because debugfs_remove recursively removes debugfs entries, the lpfc_debugfs_terminate routine is updated to remove only the parent/root debugfs directories. As such, there no longer is a need to keep track of each individual debugfs entry so clean up the unused phba dentries.

scsi: lpfc: Convert timeouts to secs_to_jiffies()

2025-03-04T03:11:47Z

Commit b35108a51cf7 ("jiffies: Define secs_to_jiffies()") introduced secs_to_jiffies(). As the value here is a multiple of 1000, use secs_to_jiffies() instead of msecs_to_jiffies() to avoid the multiplication This is converted using scripts/coccinelle/misc/secs_to_jiffies.cocci with the following Coccinelle rules: @depends on patch@ expression E; @@ -msecs_to_jiffies(E * 1000) +secs_to_jiffies(E) -msecs_to_jiffies(E * MSEC_PER_SEC) +secs_to_jiffies(E) While here, convert some timeouts that are denominated in seconds manually.

scsi: lpfc: rework lpfc_next_{online,present}_cpu()

2025-02-24T21:37:23Z

lpfc_next_online_cpu() opencodes cpumask_next_and_wrap() by using a for-loop. Use it and make the lpfc_next_online_cpu() a plain one-liner. While there, rework lpfc_next_present_cpu() similarly. Notice that cpumask_next() followed by cpumask_first() in the worst case of an empty mask may traverse the mask twice. Cpumask_next_wrap() takes care of that correctly.

scsi: lpfc: Fix unsolicited FLOGI kref imbalance when in direct attached topology

2024-08-03T01:48:05Z

In direct attached topology, certain target vendors that are quick to issue FLOGI followed by a cable pull for more than dev_loss_tmo may result in a kref imbalance for the remote port ndlp object. Add an nlp_get when the defer_flogi_acc flag is set. This is expected to balance the nlp_put in the defer_flogi_acc clause in the lpfc_issue_els_flogi() routine. Because we need to retain the ndlp ptr, reorganize all of the defer_flogi_acc information into one lpfc_defer_flogi_acc struct.
