When debugging a recent discovery customer problem it was very hard to tell what was happening with the existing discovery log messages. To fully debug the issue additional log messages were necessary. Add or extend log messages so that sufficient information is present for debugging.

In the past, the lpe32000 models, based their main support being for 32G, and as FC-AL is not supported in the FC standards past 8G, did not support FC-AL operation. This patch adds private-loop FC-AL support for the LPE32000 adapters when a link is 8G or below. To avoid conditions where link rate may change, which would cause non-connectivity to the AL device, FC-AL mode must become a persistent setting and the link kept at a speed supporting FC-AL. The patch: - Adds a pls attribute indicating whether the adapter properly supports FC-AL. - Adds support for the adapter to indicate that topology should be fixed and the topology types to be configured. - Adds a pt attribute to report the persistent topology if present.

Currently, the FW logging facility is a load/boot time parameter which requires the driver to be unloaded/reloaded or the system rebooted in order to change its configuration. Convert the logging facility to allow dynamic enablement and configuration. Specifically: - Convert the feature so that it can be enabled dynamically via an attribute. Additionally, the size of the buffer can be configured dynamically. - Add locks around states that now may be changing. - Tie the feature into debugfs so that the logs can be read at any time.

The existing "auto eq delay" mechanism was sometimes skipping over an EQ, not ramping the coalescing down under light load fast enough, and in other cases never kicked in as cpu sharing by multiple vectors didn't quite add up right. Tweak the interrupt mechanism such that: - Add a flag to the EQ to force checking for colaescing values when being serviced in the interrupt handler. The flag will be set by any CQ bound to the EQ whenever the number of CQ elements process in a single scan meets or exceeds the hardware queue notify level. E.g. there's a significant number of completions happening. - In the heartbeat work item that checks coalescing: - Replace the structure that was counting the number of EQs that interrupted on a single cpu with a new structure that looks at the EQ to see whether EQ currently has a coalescing value (thus it should be re-evaluate) or was marked by the new flag indicating heavy completions. - When a cpu, which may be servicing multiple vectors, had at least 1 EQ that should be checked, a new coalescing delay is calculated based on the number of interrupts that occurred on the cpu. - The new coalescing value is then applied to the EQs that had interrupted on the cpu.

Lower IOps performance with write operations. Perf tool shows lock contention in dma_pool_alloc and dma_pool_free related to the txrdy_payload_pool. The allocations are for dma buffers for XFER_RDY's, which actually are not needed for the FCP_TRECEIVE command as the command contents are used by the adapter to generate the IU. Remove the allocations and the associated buffer pool. Rather than leaving NULLs in buffer pointer locations, set command and sgl to indicate skipped SGLE indexes.

In lpfc_abort_handler, the lock acquire order is hbalock (irqsave), buf_lock (irq) and ring_lock (irq). The issue is that in two places the locks are released out of order - the buf_lock and the hbalock - resulting in the cpu preemption/lock flags getting restored out of order and deadlocking the cpu. Fix the unlock order by fully releasing the hbalocks as well. CC: Zhangguanghui <zhang.guanghui@h3c.com> Link: https://lore.kernel.org/r/20191018211832.7917-7-jsmart2021@gmail.comSigned-off-by:

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:

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:
