Pull SCSI updates from James Bottomley: "Updates to the usual drivers (target, ufs, smartpqi, lpfc). There are some core changes, mostly around reworking some of our user context assumptions in device put and moving some code around.

scsi: lpfc: Fix crash involving race between FLOGI timeout and devloss handler

2022-11-17T18:18:42Z

When a FLOGI completes with a sequence timeout error, a freed kref ptr dereference crash can occur due to a timing race involving ndlp referencing in lpfc_dev_loss_tmo_callbk. Fix by ensuring the driver accounts for an outstanding FLOGI when dev_loss is active. Also, don't remove the HBA_FLOGI_OUTSTANDING flag when the FLOGI is retried to allow the driver to handle the reference counts correctly in lpfc_dev_loss_tmo_handler.

scsi: lpfc: Fix MI capability display in cmf_info sysfs attribute

2022-11-17T18:18:42Z

The dynamic mi_ver value holds the currently configured MI setting. mi_ver was being displayed as part of the cmf_info sysfs attribute, when the output string meant to display MI capabilities instead. Add a mi_cap member in the lpfc_pc_sli4_params structure that will store MI capabilities during initialization so that cmf_info prints out capabilities instead of current configuration.

scsi: lpfc: Correct bandwidth logging during receipt of congestion sync WCQE

2022-11-17T18:18:42Z

The lpfc_cmf_timer adjusts phba->cmf_link_byte_count periodically and can artifically inflate bandwidth percent. During bandwidth calculation, correct for this by setting a cap of logging a maximum of 100%. Bandwidth calculation is only used for display under LOG_CGN_MGMT so there is no expectation of impacts on performance.

scsi: lpfc: Fix WQ|CQ|EQ resource check

2022-11-17T18:18:42Z

Adapter configurations with limited EQ resources may fail to initialize. Firmware resources are queried in lpfc_sli4_read_config(). The driver parameters cfg_irq_chann and cfg_hdw_queue are adjusted from defaults if constrained by firmware resources. The minimum resource check includes a special allocation for queues such as ELS, MBOX, NVME LS. However the additional reservation was also incorrectly applied to EQ resources. Reordered WQ|CQ|EQ resource checks to apply the special allocation adjustment to WQ and CQ resources only.
