When unregistering a remote port the lpfc driver would eventually wait
for the remoteport_unreg done callback. But the driver never completed
the io aborts that would allow the connections to terminate thus the
unreg done callback was never issued. Turns out the coding style of the
driver allowed for the wait to occur on the same cpu that the deferred
isr is called on. The blocking for the wait, blocked the isr, and as the
isr didn't run, the io aborts wouldn't finish.
Turns out there was never a good reason to block waiting for the unreg
done in the first place. The driver can continue execution and the ref
counting within the driver will do the right thing.
Resolve by removing the wait and patching up a few cases where the ref
counting didn't look right - mainly cases where the remote port comes
back before the aborts had completed and the unreg done had been
called. Additionally, a few places which used pointer values to guide
driver actions weren't protected by lock, so correct those.

In the lpfc discovery engine, when as a nvme target, where the driver
was performing mailbox io with the adapter for port login when a NVME
PRLI is received from the host. Rather than queue and eventually get
back to sending a response after the mailbox traffic, the driver
rejected the io with an error response.
Turns out this particular initiator didn't like the rejection values
(unable to process command/command in progress) so it never attempted a
retry of the PRLI. Thus the host never established nvme connectivity
with the lpfc target.
By changing the rejection values (to Logical Busy/nothing more), the
initiator accepted the response and would retry the PRLI, resulting in
nvme connectivity.

When enabled for both SCSI and NVME support, and connected pt2pt to a
SCSI only target, the driver nodelist entry for the remote port is left
in PRLI_ISSUE state and no SCSI LUNs are discovered. Works fine if only
configured for SCSI support.
Error was due to some of the prli points still reflecting the need to
send only 1 PRLI. On a lot of fabric configs, targets were NVME only,
which meant the fabric-reported protocol attributes were only telling
the driver one protocol or the other. Thus things worked fine. With
pt2pt, the driver must send a PRLI for both protocols as there are no
hints on what the target supports. Thus pt2pt targets were hitting the
multiple PRLI issues.
Complete the dual PRLI support. Track explicitly whether scsi (fcp) or
nvme prli's have been sent. Accurately track protocol support detected
on each node as reported by the fabric or probed by PRLI traffic.

Handling a rcv'ed PRLI incorrectly can cause the ndlp to end up in the
wrong state or the driver to ACC and PRLI when it should send LS_RJT.
The cause was due to the driver not properly looking at the PRLI type
and taking the multiple protocol support into consideration.
Resolved by adding checks in the various PRLI receive points to validate
PRLI type and reject if not valid for the enabled protocols and mode
(host vs target).

The driver is all set to handle the defer_rcv api for the nvmet_fc
transport, yet didn't properly recognize the return status when the
defer_rcv occurred. The driver treated it simply as an error and aborted
the io. Several residual issues occurred at that point.
Finish the defer_rcv support: recognize the return status when the io
request is being handled in a deferred style. This stops the rogue
aborts; Replenish the async cmd rcv buffer in the deferred receive if
needed.

NVME targets appear to randomly disconnect from the initiator when
running heavy IO.
The error is due to the host aggregate (across all controllers) io load
was beyond the maximum exchange count for nvme on the adapter. The
driver was properly returning a resource busy status, but the io load
was so great heartbeat commands would be bounced and not have a
successful retry within the fuzz amount for the nvme heartbeat (yes, a
very high io load!). Thus the target was terminating the controller due
to a keep alive failure.
Resolve by reserving a few exchanges (by counters) which can be used
when the adapter is out of normal exchanges and the command is a NVME
heartbeat command. As counters are used, while the reserved command is
outstanding, as soon as any other exchange completes, the counters are
adjusted and the reserved count is replenished. The heartbeat completes
execution in a normal fashion.

For v3 hw SAS, it supports configuring power state from D0 to D3 for entering
Low Power status and power state from D3 to D0 for quit Low Power status.
When power state from D0 to D3, HW will send FLR to clear the registers of
ECAM and BAR space, and when power state from D3 to D0, it will clear the
registers of ECAM space only.
So when suspend, need to do like controller reset (including disable
interrupts/DQ/PHY/BUS), and also release slots after FLR. When resume,
re-config the registers of BAR space.

This patch fix SAS_QUEUE_FULL problem. The test situation is close port while
running IO.
In sas_eh_handle_sas_errors(), SCSI EH will free sas_task of the device if
lldd_I_T_nexus_reset() return TMF_RESP_FUNC_COMPLETE or -ENODEV. But in our
SAS driver, we only free slots of the device when the return value is
TMF_RESP_FUNC_COMPLETE. So if the return value is -ENODEV, the slot resource
will not free any more.
As an solution, we should also free slots of the device in
lldd_I_T_nexus_reset() if the return value is -ENODEV.

We should do internal abort dev before TMF_ABORT_TASK_SET and TMF_LU_RESET.
Because we may only have done internal abort for single IO in the earlier part
of SCSI EH process. Even the internal abort to the single IO, we also don't
know whether it is successful.
Besides, we should release slots of the device in hisi_sas_abort_task_set() if
the abort is successful.

Normally, hardware should ensure that internal abort timeout will never
happen. If happen, it would be an SoC failure. What's more, HW will not
process any other commands if an internal abort hasn't return CQ, and they
will time out also.
So, we should judge the result of internal abort in SCSI EH, if it is failed,
we should give up to do TMF/softreset and return failure to the upper layer
directly.
This patch do following things to achieve this:
1. When internal abort timeout happened, we set return value to -EIO in
hisi_sas_internal_task_abort().
2. If prep_abort() is not support, let hisi_sas_internal_task_abort() return
TMF_RESP_FUNC_FAILED.
3. If hisi_sas_internal_task_abort() return an negative number, it can be
thought that it not executed properly or internal abort timeout. Then we
won't do behind TMF or softreset, and return failure directly.

We should do link reset of PHY when identify timeout or STP link timeout. They
are internal events of SOC and are notified to driver through interrupts of
CHL_INT2.
Besides, we should add an delay work to do link reset as it needs sleep. So,
this patch add an new PHY event HISI_PHYE_LINK_RESET for this.
Notes: v2 HW doesn't report the event of STP link timeout. So, we only need
to handle event of identify timeout for v2 HW.

Sometimes it is required to know when the controller reset has completed and
also if it has completed successfully. For such places, we call
hisi_sas_controller_reset() directly before. That may lead to multiple calls
to this function.
This patch create a per-reset structure which contains a completion structure
and status flag to know when the reset completes and also the status. It is
also in hisi_hba.wq to do reset work.
As all host reset works are done in hisi_hba.wq, we don't worry multiple calls

This patch do following optimizations to host controller reset:
1. Unblock scsi requests before rescanning topology, as SCSI command need be
used if new device is found during rescanning topology.
2. Remove drain_workqueue(hisi_hba->wq) and drain_workqueue(shost->work_q), as
there is no need to ensure that all PHYs event are done before exiting host
reset.
3. Improve message print level of host reset. Host reset is an important and
very few occurrence event. We should know its progress even when not

Currently refreshing the PHY port id after reset is done in the rescan
topology function, which is quite late in the reset process. It could be moved
earlier in the process, as the port id can be refreshed once the PHYs become
ready.
In addition to this, we should set the hisi_sas_dev port id to 0xff (invalid
port id) if all PHYs of this port remain down for the same device.

In certain scenarios we may just want to clear the ITCT for a device, and not
free other resources like the SATA bitmap using in v2 hw.
To facilitate this, this patch relocates the code of clearing ITCT from
free_device() to a new hw interface clear_itct(). Then for some hw, we should
not realise free_device() if there's nothing left to do for it.

Firstly, secs is unsigned so the check is always going to be false.
Secondly, if secs was signed the proceeding calculation of secs is never

In most cases, this can be addressed by correctly calling strlcpy and
strlcat instead of strncpy/strncat, with the size of the destination
buffer as the last argument.
For consistency, I'm changing the other callers of strncpy() in this
driver the same way.

Although it is important to be able to trigger the code in the SCSI core
for SCSI_MLQUEUE_HOST_BUSY handling, currently it is nontrivial to
trigger that code. Hence this patch that adds a new error injection
option to the scsi_debug driver for making the .queue_rq()
implementation of this driver return SCSI_MLQUEUE_HOST_BUSY.

Commit 56f3d383f37b ("scsi: scsi_devinfo: Add TRY_VPD_PAGES to HITACHI
OPEN-V blacklist entry") modified some Hitachi entries:
HITACHI is always supporting VPD pages, even though it's claiming to
support SCSI Revision 3 only.
The same should have been done also for HP-rebranded.

Commit 627511e3e675 ("[SCSI] scsi_devinfo: update Hitachi entries (v2)")
modified some Hitachi entries:
Four models, OPEN-/DF400/DF500/DISK-SUBSYSTEM, can handle
REPORT_LUN, and the BLIST_REPORTLUN2 flag needs to be set. And DF600
doesn't require any flags because it returns ANSI 03h (SPC).
The same should have been done also for HP counterparts.

When driver is loaded in Target/Dual mode, it creates QPair to support
MQ and allocates resources for each QPair. This Qpair initialization is
delayed until the FW personality is changed to Dual/Target mode by
issuing chip reset. At the time of chip reset firmware is re-initilized
in correct personality all the QPairs are initialized by sending
MBC_INITIALIZE_MULTIQ (001Fh).
This patch fixes memory leak by adding check to issue
MBC_INITIALIZE_MULTIQ command only while deleting rsp/req queue when the
flag is set for initiator mode, and clean up QPair resources correctly
during the driver unload. This MBX does not need to be issued for
Target/Dual mode because chip reset will reset ISP.
