[ Upstream commit 4ddf01f2f1504fa08b766e8cfeec558e9f8eef6c ]
There are cases after NPIV deletion where the fabric switch still believes
the NPIV is logged into the fabric. This occurs when a vport is
unregistered before the Remove All DA_ID CT and LOGO ELS are sent to the
fabric.
Currently fc_remove_host(), which calls dev_loss_tmo for all D_IDs including
the fabric D_ID, removes the last ndlp reference and frees the ndlp rport
object. This sometimes causes the race condition where the final DA_ID and
LOGO are skipped from being sent to the fabric switch.
Fix by moving the fc_remove_host() and scsi_remove_host() calls after DA_ID
and LOGO are sent.

[ Upstream commit 4623713e7ade46bfc63a3eade836f566ccbcd771 ]
IRQF_ONESHOT is found to mask HBA generated interrupts when thread_fn is
running. As a result, some EQEs/CQEs miss timely processing resulting in
SCSI layer attempts to abort commands due to io_timeout. Abort CQEs are
also not processed leading to the observations of hangs and spam of "0748
abort handler timed out waiting for aborting I/O" log messages.
Remove the IRQF_ONESHOT flag. The cmpxchg and xchg atomic operations on
lpfc_queue->queue_claimed already protect potential parallel access to an
EQ/CQ should the thread_fn get interrupted by the primary irq handler.

[ Upstream commit bb011631435c705cdeddca68d5c85fd40a4320f9 ]
Typically when an out of resource CQE status is detected, the
lpfc_ramp_down_queue_handler() logic is called to help reduce I/O load by
reducing an sdev's queue_depth.
However, the current lpfc_rampdown_queue_depth() logic does not help reduce
queue_depth. num_cmd_success is never updated and is always zero, which
means new_queue_depth will always be set to sdev->queue_depth. So,
new_queue_depth = sdev->queue_depth - new_queue_depth always sets
new_queue_depth to zero. And, scsi_change_queue_depth(sdev, 0) is
essentially a no-op.
Change the lpfc_ramp_down_queue_handler() logic to set new_queue_depth
equal to sdev->queue_depth subtracted from number of times num_rsrc_err was
incremented. If num_rsrc_err is >= sdev->queue_depth, then set
new_queue_depth equal to 1. Eventually, the frequency of Good_Status
frames will signal SCSI upper layer to auto increase the queue_depth back
to the driver default of 64 via scsi_handle_queue_ramp_up().

hbalock. Thus, lpfc_worker_wake_up() should not be called while holding the
hbalock to avoid potential deadlock.

[ Upstream commit f733a76ea0a9a84aee4ac41b81fad4d610ecbd8e ]
To reduce usage of and contention for hbalock, a separate dedicated lock is
used to protect ras_fwlog state.

[ Upstream commit 429846b4b6ce9853e0d803a2357bb2e55083adf0 ]
When the "storcli2 show" command is executed for eHBA-9600, mpi3mr driver
prints this WARNING message:
memcpy: detected field-spanning write (size 128) of single field "bsg_reply_buf->reply_buf" at drivers/scsi/mpi3mr/mpi3mr_app.c:1658 (size 1)
WARNING: CPU: 0 PID: 12760 at drivers/scsi/mpi3mr/mpi3mr_app.c:1658 mpi3mr_bsg_request+0x6b12/0x7f10 [mpi3mr]
The cause of the WARN is 128 bytes memcpy to the 1 byte size array "__u8
replay_buf[1]" in the struct mpi3mr_bsg_in_reply_buf. The array is intended
to be a flexible length array, so the WARN is a false positive.
To suppress the WARN, remove the constant number '1' from the array
declaration and clarify that it has flexible length. Also, adjust the
memory allocation size to match the change.

[ Upstream commit c214ed2a4dda35b308b0b28eed804d7ae66401f9 ]
The session resources are used by FW and driver when session is offloaded,
once session is uploaded these resources are not used. The lock is not
required as these fields won't be used any longer. The offload and upload
calls are sequential, hence lock is not required.
This will suppress following BUG_ON():
