8156d378c4 scsi: lpfc: Revise interrupt coalescing for missing scenarios
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.

ea85a20cd5 scsi: lpfc: Remove lock contention target write path
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.

91a52b617c scsi: lpfc: Fix hardlockup in lpfc_abort_handler
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.

324e1c4020 scsi: lpfc: Fix bad ndlp ptr in xri aborted handling
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.

feff8b3d84 scsi: lpfc: Fix SLI3 hba in loop mode not discovering devices
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.

0a5ce73197 scsi: lpfc: Fix reporting of read-only fw error errors
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.

8f8fed0cdb scsi: core: save/restore command resid for error handling
When a non-passthrough command is terminated with CHECK CONDITION, request
sense is executed by hijacking the command descriptor. Since
scsi_eh_prep_cmnd() and scsi_eh_restore_cmnd() do not save/restore the
original command resid, the value returned on failure of the original
command is lost and replaced with the value set by the execution of the
request sense command. This value may in many instances be unaligned to the
device sector size, causing sd_done() to print a warning message about the
incorrect unaligned resid before the command is retried.

Fix this problem by saving the original command residual in struct
scsi_eh_save using scsi_eh_prep_cmnd() and restoring it in
scsi_eh_restore_cmnd(). In addition, to make sure that the request sense
command is executed with a correctly initialized command structure, also
reset the residual to 0 in scsi_eh_prep_cmnd() after saving the original
command value in struct scsi_eh_save.

Commit 88263208dd ("scsi: qla2xxx: Complain if sp->done() is not called
from the completion path") introduced the WARN_ON_ONCE in
qla2x00_status_cont_entry(). The assumption was that there is only one
status continuations element. According to the firmware documentation it is
possible that multiple status continuations are emitted by the firmware.

I've got a report about a UAS drive enclosure reporting back Sense: Logical
unit access not authorized if the drive it holds is password protected.
While the drive is obviously unusable in that state as a mass storage
device, it still exists as a sd device and when the system is asked to
perform a suspend of the drive, it will be sent a SYNCHRONIZE CACHE. If
that fails due to password protection, the error must be ignored.

Since 'commit fc8d0590d9 ("libcxgbi: Add ipv6 api to driver")' was
introduced, there is no call to csk_print_port() and csk_print_ip() is
made.

Hence kernel build with clang complains below message:
   drivers/scsi/cxgbi/libcxgbi.c:2287:19: warning: unused function 'csk_print_port' [-Wunused-function]
   static inline int csk_print_port(struct cxgbi_sock *csk, char *buf)

   static inline int csk_print_ip(struct cxgbi_sock *csk, char *buf)
                        ^

Remove csk_print_port() and csk_print_ip() to stop warning.
