2022-06-13scsi: iscsi: Exclude zero from the endpoint ID rangeSergey Gorenko
The kernel returns an endpoint ID as r.ep_connect_ret.handle in the iscsi_uevent. The iscsid validates a received endpoint ID and treats zero as an error. The commit referenced in the fixes line changed the endpoint ID range, and zero is always assigned to the first endpoint ID. So, the first attempt to create a new iSER connection always fails.

2022-06-10scsi: qla2xxx: edif: Fix slow session teardownQuinn Tran
User experience slow recovery when target device went through a stop/start of the authentication application (app_stop/app_start). Between the period of app_stop and app_start on the target device, target device choose to send ELS Reject for any receive AUTH ELS command. At this time, authentication application does not do ELS reject if it encounters error. Therefore, AUTH ELS reject signify authentication application is not running. If driver passes up the AUTH ELS Reject to the authentication application, then it would result in authentication application retrying/resending the same AUTH ELS command again + delay. As a work around, driver should trigger a session tear down where it tells the local authentication application to also tear down. At the next relogin, both sides are then synchronized.

Nevertheless, gcc complains because the whole Mpi2SasIOUnitPage1_t struct is 32 bytes in size and thus doesn't fit into those 20 bytes.

2022-06-07scsi: qla2xxx: edif: Add bsg interface to read doorbell eventsQuinn Tran
Add bsg interface for app to read doorbell events. This interface lets driver know how much app can read based on return buffer size. When the next event(s) occur, driver will return the bsg_job with the event(s) in the return buffer. If there is no event to read, driver will hold on to the bsg_job up to few seconds as a way to control the polling interval.

2022-06-07scsi: lpfc: Fix port stuck in bypassed state after LIP in PT2PT topologyJames Smart
After issuing a LIP, a specific target vendor does not ACC the FLOGI that lpfc sends. However, it does send its own FLOGI that lpfc ACCs. The target then establishes the port IDs by sending a PLOGI. lpfc PLOGI_ACCs and starts the RPI registration for DID 0x000001. The target then sends a LOGO to the fabric DID. lpfc is currently treating the LOGO from the fabric DID as a link down and cleans up all the ndlps. The ndlp for DID 0x000001 is put back into NPR and discovery stops, leaving the port in stuck in bypassed mode. Change lpfc behavior such that if a LOGO is received for the fabric DID in PT2PT topology skip the lpfc_linkdown_port() routine and just move the fabric DID back to NPR.

2022-06-07scsi: lpfc: Resolve NULL ptr dereference after an ELS LOGO is abortedJames Smart
A use-after-free crash can occur after an ELS LOGO is aborted. Specifically, a nodelist structure is freed and then ndlp->vport->cfg_log_verbose is dereferenced in lpfc_nlp_get() when the discovery state machine is mistakenly called a second time with NLP_EVT_DEVICE_RM argument. Rework lpfc_cmpl_els_logo() to prevent the duplicate calls to release a nodelist structure.

2022-06-07scsi: lpfc: Resolve some cleanup issues following abort path refactoringJames Smart
Refactoring and consolidation of abort paths: - lpfc_sli4_abort_fcp_cmpl() and lpfc_sli_abort_fcp_cmpl() are combined into a single generic lpfc_sli_abort_fcp_cmpl() routine. Thus, remove extraneous lpfc_sli4_abort_fcp_cmpl() prototype declaration. - lpfc_nvme_abort_fcreq_cmpl() abort completion routine is called with a mismatched argument type. This may result in misleading log message content. Update to the correct argument type of lpfc_iocbq instead of lpfc_wcqe_complete. The lpfc_wcqe_complete should be derived from the lpfc_iocbq structure.
