In cases where I/O may be aborted, such as driver unload or link bounces, the system will crash based on a bad ndlp pointer. Example: RIP: 0010:lpfc_sli4_abts_err_handler+0x15/0x140 [lpfc] ... lpfc_sli4_io_xri_aborted+0x20d/0x270 [lpfc] lpfc_sli4_sp_handle_abort_xri_wcqe.isra.54+0x84/0x170 [lpfc] lpfc_sli4_fp_handle_cqe+0xc2/0x480 [lpfc] __lpfc_sli4_process_cq+0xc6/0x230 [lpfc] __lpfc_sli4_hba_process_cq+0x29/0xc0 [lpfc] process_one_work+0x14c/0x390 Crash was caused by a bad ndlp address passed to I/O indicated by the XRI aborted CQE. The address was not NULL so the routine deferenced the ndlp ptr. The bad ndlp also caused the lpfc_sli4_io_xri_aborted to call an erroneous io handler. Root cause for the bad ndlp was an lpfc_ncmd that was aborted, put on the abort_io list, completed, taken off the abort_io list, sent to lpfc_release_nvme_buf where it was put back on the abort_io list because the lpfc_ncmd->flags setting LPFC_SBUF_XBUSY was not cleared on the final completion. Rework the exchange busy handling to ensure the flags are properly set for both scsi and nvme.

When operating in private loop mode, PLOGI exchanges are racing and the driver tries to abort it's PLOGI. But the PLOGI abort ends up terminating the login with the other end causing the other end to abort its PLOGI as well. Discovery never fully completes. Fix by disabling the PLOGI abort when private loop and letting the state machine play out. Link: https://lore.kernel.org/r/20191018211832.7917-5-jsmart2021@gmail.comSigned-off-by:

Fix lockdep error in __lpfc_sli_ringtx_put(): The hbalock is valid for sli3, but not for sli4. Change lockdep to look at ring lock if sli4. Also update comment in __lpfc_sli_issue_iocb_s4() to reflect proper lock. Note: lockdep check is already correct.

When the adapter FW is administratively set to RO mode, a FW update triggered by the driver's sysfs attribute will fail. Currently, the driver's logging mechanism does not properly parse the adapter return codes and print a meaningful message. This oversight prevents quick diagnosis in the field. Parse the adapter return codes for Write_Object and write an appropriate message to the system console.

Currently, lpfc_nvmet_mrq is always scaled back to the min(lpfc_nvmet_mrq, lpfc_irq_chann). There's no reason to reduce it to the number of interrupt vectors. Rather, it should be scaled down based on the number of hardware queues for the system (if lower than max of 16). Change scaling to use hardware queue count rather than interrupt vector count.

RFC 2307 states: For CHAP [RFC1994], in the first step, the initiator MUST send: CHAP_A=<A1,A2...> Where A1,A2... are proposed algorithms, in order of preference. ... For the Algorithm, as stated in [RFC1994], one value is required to be implemented: 5 (CHAP with MD5) LIO currently checks for this value by only comparing a single byte in the tokenized Algorithm string, which means that any value starting with a '5' (e.g. "55") is interpreted as "CHAP with MD5". Fix this by comparing the entire tokenized string. Reviewed-by:Lee Duncan <lduncan@suse.com> Reviewed-by:

The problem is the driver detects FastResponse bit set and saves it to Fib's flags to not check IO response status, but it never clears it for next IO. Hence the next IO will pick up FastResponse bit to not check the IO response status and fail to report any type IO error to kernel Link: https://lore.kernel.org/r/1571120524-6037-3-git-send-email-balsundar.p@microsemi.comSigned-off-by:
