When lpfc is handling a solicited and unsolicited PLOGI with another
initiator, the remote initiator is never recovered. The node for the
initiator is erroneouosly removed and all resources released.
In lpfc_cmpl_els_plogi(), when lpfc_els_retry() returns a failure code, the
driver is calling the state machine with a device remove event because the
remote port is not currently registered with the SCSI or NVMe
transports. The issue is that on a PLOGI "collision" the driver correctly
aborts the solicited PLOGI and allows the unsolicited PLOGI to complete the
process, but this process is interrupted with a device_rm event.
Introduce logic in the PLOGI completion to capture the PLOGI collision
event and jump out of the routine. This will avoid removal of the node.
If there is no collision, the normal node removal will occur.

The driver is crashing due to a bad pointer during driver load due in an
adisc acc receive routine. The driver is missing node get/put in the
mbx_resume_rpi paths.
Fix by adding the proper gets and puts into the resume_rpi path.

An 'unexpected timeout' message may be seen in a point-2-point topology.
The message occurs when a PLOGI is received before the driver is notified
of FLOGI completion. The FLOGI completion failure causes discovery to be
triggered for a second time. The discovery timer is restarted but no new
discovery activity is initiated, thus the timeout message eventually
appears.
In point-2-point, when discovery has progressed before the FLOGI completion
is processed, it is not a failure. Add code to FLOGI completion to detect
that discovery has progressed and exit the FLOGI handling (noop'ing it).

When processing an NVMe ERSP IU which didn't match the optimized CQE-only
path, the status was being left to the WQE status. WQE status is non-zero
as it is indicating a non-optimized completion that needs to be handled by
the driver.
Fix by clearing the status field when falling into the non-optimized
case. Log message added to track optimized vs non-optimized debug.

While testing NPIV and watching logins and used RPI levels, it was seen the
used RPI count was much higher than the number of remote ports discovered.
Code inspection showed that remote port removals on any NPIV instance are
releasing the RPI, but not performing an UNREG_RPI with the adapter thus
the reference counting never fully drops and the RPI is never fully
released. This was happening on NPIV nodes due to a log of fabric ELS's to
fabric addresses. This lack of UNREG_RPI was introduced by a prior node
rework patch that performed the UNREG_RPI as part of node cleanup.
To resolve the issue, do the following:
- Restore the RPI release code, but move the location to so that it is in
line with the new node cleanup design.
- NPIV ports now release the RPI and drop the node when the caller sets
the NLP_RELEASE_RPI flag.
- Set the NLP_RELEASE_RPI flag in node cleanup which will trigger a
release of RPI to free pool.
- Ensure there's an UNREG_RPI at LOGO completion so that RPI release is
completed.
- Stop offline_prep from skipping nodes that are UNUSED. The RPI may
not have been released.
- Stop the default RPI handling in lpfc_cmpl_els_rsp() for SLI4.
- Fixed up debugfs RPI displays for better debugging.

The dump command for reading a region passes a requested read length
specified in words (4-byte units). The response overwrites the same field
with the actual number of bytes read.
The mailbox handler for DUMP which reads VPD data (region 23) is treating
the response field as if it were still a word_cnt, thus multiplying it by 4
to set the read's "length". Given the read value was calculated based on
the size of the read buffer, the longer response length runs off the end of
the buffer.
Fix by reworking the code to use the response field as a byte count.

In devloss timer handler and in backend calls to terminate remote port I/O,
there is logic to walk through all active IOCBs and validate them to
potentially trigger an abort request. This logic is causing illegal memory
accesses which leads to a crash. Abort IOCBs, which may be on the list, do
not have an associated lpfc_io_buf struct. The driver is trying to map an
lpfc_io_buf struct on the IOCB and which results in a bogus address thus
the issue.
Fix by skipping over ABORT IOCBs (CLOSE IOCBs are ABORTS that don't send
ABTS) in the IOCB scan logic.

The lpfc_hdw_queue attribute is to set the number of hardware queues to be
created on the adapter. Normally, the value is set to a default, which
allows the hw queue count to be sized dynamically based on adapter
capabilities, CPU/platform architecture, or CPU type. Currently, when
lpfc_hdw_queue is set to a specific value, is has no effect and the dynamic
sizing occurs.
The routine checking whether parameters are default or not ignores the
lpfc_hdw_queue setting and invokes the dynamic logic.
Fix the routine to additionally check the lpfc_hdw_queue attribute value
before using dynamic scaling. Additionally, SLI-3 supports only a small
number of queues with dedicated functions, thus it needs to be exempted
from the variable scaling and set to the expected values.

FDMI registration needs to be performed after every login with the FC Mgmt
service. The flag the driver is using to track registration is cleared on
link up, but never on Mgmt service logout/re-login.
Fix by clearing the flag whenever a new login is completed with the FC Mgmt
service.
While perusing the flag use, logging was performed as if FDMI registration
occurred on vports. However, it is limited to the physical port only.
Revise the logging to reflect physical port based.

During target port swap, the swap logic ignores the DROPPED flag in the
nodes. As a node then moves into the UNUSED state, the reference count will
be dropped. If a node is later reused and moved out of the UNUSED state, an
access can result in a use-after-free assert.
Fix by having the port swap logic propagate the DROPPED flag when switching
nodes. This will avoid reference from being dropped.

In SLI-4, when performing a mailbox command with MBX_POLL, the driver uses
the BMBX register to send the command rather than the MQ. A flag is set
indicating the BMBX register is active and saves the mailbox job struct
(mboxq) in the mbox_active element of the adapter. The routine then waits
for completion or timeout. The mailbox job struct is not freed by the
routine. In cases of timeout, the adapter will be reset. The
lpfc_sli_mbox_sys_flush() routine will clean up the mbox in preparation for
the reset. It clears the BMBX active flag and marks the job structure as
MBX_NOT_FINISHED. But, it never frees the mboxq job structure. Expectation
in both normal completion and timeout cases is that the issuer of the mbx
command will free the structure. Unfortunately, not all calling paths are
freeing the memory in cases of error.
All calling paths were looked at and updated, if missing, to free the mboxq
memory regardless of completion status.

During target port-swap testing with link flips, the initiator could
encounter PRLI errors. If the target node disappears permanently, the ndlp
is found stuck in UNUSED state with ref count of 1. The rmmod of the driver
will hang waiting for this node to be freed.
While handling a link error in PRLI completion path, the code intends to
skip triggering the discovery state machine. However this is causing the
final reference release path to be skipped. This causes the node to be
stuck with ref count of 1
Fix by ensuring the code path triggers the device removal event on the node
state machine.

Call traces are being seen that result from a nodelist structure ref
counting error. They are typically seen after transmission of an LS_RJT ELS
response.
Aged code in lpfc_cmpl_els_rsp() calls lpfc_nlp_not_used() which, if the
ndlp reference count is exactly 1, will decrement the reference count.
Previously lpfc_nlp_put() was within lpfc_els_free_iocb(), and the 'put'
within the free would only be invoked if cmdiocb->context1 was not NULL.
Since the nodelist structure reference count is decremented when exiting
lpfc_cmpl_els_rsp() the lpfc_nlp_not_used() calls are no longer required.
Calling them is causing the reference count issue.
Fix by removing the lpfc_nlp_not_used() calls.

Fix a crash caused by a double put on the node when the driver completed an
ACC for an unsolicted abort on the same node. The second put was executed
by lpfc_nlp_not_used() and is wrong because the completion routine executes
the nlp_put when the iocbq was released. Additionally, the driver is
issuing a LOGO then immediately calls lpfc_nlp_set_state to put the node
into NPR. This call does nothing.
Remove the lpfc_nlp_not_used call and additional set_state in the
completion routine. Remove the lpfc_nlp_set_state post issue_logo. Isn't
necessary.

Rmmod on SLI-4 adapters is sometimes hitting a bad ptr dereference in
lpfc_els_free_iocb().
A prior patch refactored the lpfc_sli_abort_iocb() routine. One of the
changes was to convert from building/sending an abort within the routine to
using a common routine. The reworked routine passes, without modification,
the pring ptr to the new common routine. The older routine had logic to
check SLI-3 vs SLI-4 and adapt the pring ptr if necessary as callers were
passing SLI-3 pointers even when not on an SLI-4 adapter. The new routine
is missing this check and adapt, so the SLI-3 ring pointers are being used
in SLI-4 paths.
Fix by cleaning up the calling routines. In review, there is no need to
pass the ring ptr argument to abort_iocb at all. The routine can look at
the adapter type itself and reference the proper ring.

On a setup with a dual port HBA and both ports direct connected, an rmmod
hangs momentarily when we log an Illegal State Transition. Once it resumes,
a nodelist not empty logic is hit, which forces rmmod to cleanup and exit.
We're missing a state transition case in the discovery engine.
Fix by adding a case for a DEVICE_RM event while in the unmapped state to
avoid illegal state transition log message.

The debugfs nodeinfo output gets jumbled when no rpri or a defer entry is
displayed. The misalignment makes it difficult to read.
Change the format to consistently print out a 4 character rpi, and turn
defer into a suffix.

While testing target port swap test with ADISC enabled, several nodes
remain in UNUSED state. These nodes are never freed and rmmod hangs for
long time before finising with "0233 Nodelist not empty" error.
During PLOGI completion lpfc_plogi_confirm_nport() looks for existing nodes
with same WWPN. If found, the existing node is used to continue discovery.
The node on which plogi was performed is freed. When ADISC is enabled, an
ADISC els request is triggered in response to an RSCN. It's possible that
the ADISC may be rejected by the remote port causing the ADISC completion
handler to clear the port and node name in the node. If this occurs, if a
PLOGI is received it causes a node lookup based on wwpn to now fail,
causing the port swap logic to kick in which allocates a new node and swaps
to it. This effectively orphans the original node structure.
Fix the situation by detecting when the lookup fails and forgo the node
swap and node allocation by using the node on which the PLOGI was issued.

The driver is seeing a scenario where PLOGI response was issued and traffic
is arriving while the adapter is still setting up the login context. This
is resulting in errors handling the traffic.
Change the driver so that PLOGI response is sent after the login context
has been setup to avoid the situation.

When connected in pt2pt mode, there is a scenario where the remote port
significantly delays sending a response to our FLOGI, but acts on the FLOGI
it sent us and proceeds to PLOGI/PRLI. The FLOGI ends up timing out and
kicks off recovery logic. End result is a lot of unnecessary state changes
and lots of discovery messages being logged.
Fix by terminating the FLOGI and noop'ing its completion if we have already
accepted the remote ports FLOGI and are now processing PLOGI.
