The VMID feature adds an extra application services header to each frame.
As such, the loopback test path is updated to accommodate the extra
application header.
Changes include filling in APPID and WQES bit fields for XMIT_SEQUENCE64
commands, a special loopback source APPID for verifying received loopback
data matches what is sent, and increasing ELS WQ size to accommodate the
APPID field in loopback test mode.

Revise certain log messages marked as KERN_ERR LOG_TRACE_EVENT to
KERN_WARNING and use the lpfc_vlog_msg() macro to still log the event. The
benefit is that events of interest are still logged and the entire trace
buffer is not dumped with extraneous logging information when using default
lpfc_log_verbose driver parameter settings.
Also, delete the keyword "fail" from such log messages as they aren't
really causes for concern. The log messages are more for warnings to a SAN
admin about SAN activity.

Deleting an NPIV instance requires all fabric ndlps to be released before
an NPIV's resources can be torn down. Failure to release fabric ndlps
beforehand opens kref imbalance race conditions. Fix by forcing the DA_ID
to complete synchronously with usage of wait_queue.

With a FLOGI outstanding and loss of physical link connection to the fabric
for the duration of dev_loss_tmo, there is a fabric ndlp kref imbalance
that decrements the kref and sets the NLP_IN_RECOV_POST_DEV_LOSS flag at
the same time.
The issue is that when the FLOGI completion routine executes, the fabric
ndlp could already be freed because of the final kref put from the
dev_loss_tmo handler. Fix by early returning before the ndlp kref put if
the ndlp is deemed a candidate for NLP_IN_RECOV_POST_DEV_LOSS in the FLOGI
completion routine.

It's possible for the driver to send a CMF_SYNC_WQE to nonresponsive
firmware during reset of the adapter. The phba link_state conditional
check is currently a strict == LPFC_LINK_DOWN, which does not cover
initialization states before reaching the LPFC_LINK_UP state.
Update the phba->link_state conditional to < LPFC_LINK_UP so that all
initialization states are covered before allowing sending CMF_SYNC_WQE.
Update taking of the hbalock to be during this link_state check as well.

During HBA stress testing, a spam of received PLOGIs exposes a resource
recovery bug causing leakage of lpfc_sqlq entries from the global
phba->sli4_hba.lpfc_els_sgl_list.
The issue is in lpfc_els_flush_cmd(), where the driver attempts to recover
outstanding ELS sgls when walking the txcmplq. Only CMD_ELS_REQUEST64_CRs
and CMD_GEN_REQUEST64_CRs are added to the abort and cancel lists. A check
for CMD_XMIT_ELS_RSP64_WQE is missing in order to recover LS_ACC usages of
the phba->sli4_hba.lpfc_els_sgl_list too.
Fix by adding CMD_XMIT_ELS_RSP64_WQE as part of the txcmplq walk when
adding WQEs to the abort and cancel list in lpfc_els_flush_cmd(). Also,
update naming convention from CRs to WQEs.

During controller transitioning to READY state, if the controller is found
in transient states ("becoming ready" or "reset requested"), driver waits
for 510 secs even if the controller transitions out of these states
early. This causes an unnecessary delay of 510 secs in the overall firmware
initialization sequence.
Poll the controller state periodically (every 100 milliseconds) while
waiting for the controller to come out of the mentioned transient
states. Once the controller transits out of the transient states, come out
of the wait loop.

command to the SCSI device that is being resumed. That command is not
retried in case of a unit attention and hence may fail. An example:

There are some scenarios that can occur, such as performing an upgrade of
the virtual I/O server, where the supported max transfer of the backing
device for an ibmvfc HBA can change. If the max transfer of the backing
device decreases, this can cause issues with previously discovered
LUNs. This patch accomplishes two things. First, it changes the default
ibmvfc max transfer value to 1MB. This is generally supported by all
backing devices, which should mitigate this issue out of the box. Secondly,
it adds a module parameter, enabling a user to increase the max transfer
value to values that are larger than 1MB, as long as they have configured
these larger values on the virtual I/O server as well.

A previous change was introduced to prevent data loss during a power-on
reset when a tape is present inside the drive. This commit set the
"pos_unknown" flag to true to avoid operations that could compromise data
by performing actions from an untracked position. The relevant change is
commit 9604eea5bd3a ("scsi: st: Add third party poweron reset handling")
As a consequence of this change, a new issue has surfaced: the driver now
returns an "Input/output error" even for empty drives when the drive, host,
or bus is reset. This issue stems from the "flush_buffer" function, which
first checks whether the "pos_unknown" flag is set. If the flag is set, the
user will encounter an "Input/output error" until the tape position is
known again. This behavior differs from the previous implementation, where
empty drives were not affected at system start up time, allowing tape
software to send commands to the driver to retrieve the drive's status and
other information.
The current behavior prioritizes the "pos_unknown" flag over the
"ST_NO_TAPE" status, leading to issues for software that detects drives
during system startup. This software will receive an "Input/output error"
until a tape is loaded and its position is known.
To resolve this, the "ST_NO_TAPE" status should take priority when the
drive is empty, allowing communication with the drive following a power-on
reset. At the same time, the change should continue to protect data by
maintaining the "pos_unknown" flag when the drive contains a tape and its
position is unknown.

Don Brace <don.brace@microchip.com> says:
These patches are based on Martin Petersen's 6.12/scsi-queue tree
https://git.kernel.org/pub/scm/linux/kernel/git/mkp/scsi.git
6.12/scsi-queue
There are two functional changes:
smartpqi-add-fw-log-to-kdump
smartpqi-add-counter-for-parity-write-stream-requests
There are three minor bug fixes:
smartpqi-fix-stream-detection
smartpqi-fix-rare-system-hang-during-LUN-reset
smartpqi-fix-volume-size-updates
The other two patches add PCI-IDs for new controllers and change the
driver version.
This set of changes consists of:
* smartpqi-add-fw-log-to-kdump
During a kdump, the driver tells the controller to copy its logging
information to some pre-allocated buffers that can be analyzed
later.
This is a "feature" driven capability and is backward compatible
with existing controller FW.
This patch renames some prefixes for OFA (Online-Firmware Activation
ofa_*) buffers to host_memory_*. So, not a lot of actual functional
changes to smartpqi_init.c, mainly determining the memory size
allocation.
We added a function to notify the controller to copy debug data into
host memory before continuing kdump.
Most of the functional changes are in smartpqi_sis.c where the
actual handshaking is done.
* smartpqi-fix-stream-detection
Correct some false write-stream detections. The data structure used
to check for write-streams was not initialized to all 0's causing
some false write stream detections. The driver sends down streamed
requests to the raid engine instead of using AIO bypass for some
extra performance. (Potential full-stripe write verses Read Modify
Write).
False detections have not caused any data corruption. Found by
internal testing. No known externally reported bugs.
* smartpqi-add-counter-for-parity-write-stream-requests
Adding some counters for raid_bypass and write streams. These two
counters are related because write stream detection is only checked
if an I/O request is eligible for bypass (AIO).
The bypass counter (raid_bypass_cnt) was moved into a common
structure (pqi_raid_io_stats) and changed to type __percpu. The
write stream counter is (write_stream_cnt) has been added to this
same structure.
These counters are __percpu counters for performance. We added a
sysfs entry to show the write stream count. The raid bypass counter
sysfs entry already exists.
Useful for checking streaming writes. The change in the sysfs entry
write_stream_cnt can be checked during AIO eligible write
operations.
* smartpqi-add-new-controller-PCI-IDs
Adding support for new controller HW. No functional changes.
* smartpqi-fix-rare-system-hang-during-LUN-reset
We found a rare race condition that can occur during a LUN reset. We
were not emptying our internal queue completely.
There have been some rare conditions where our internal request
queue has requests for multiple LUNs and a reset comes in for one of
the LUNs. The driver waits for this internal queue to empty. We were
only clearing out the requests for the LUN being reset so the
request queue was never empty causing a hang.
The Fix:
For all requests in our internal request queue:
Complete requests with DID_RESET for queued requests for the
device undergoing a reset.
Complete requests with DID_REQUEUE for all other queued requests.
Found by internal testing. No known externally reported bugs.
* smartpqi-fix-volume-size-updates
The current code only checks for a size change if there is also a
queue depth change. We are separating the check for queue depth and
the size changes.
Found by internal testing. No known bugs were filed.

Correct a rare case where in a LUN reset occurs on a device and I/O
requests for other devices persist in the driver's internal request queue.
Part of a LUN reset involves waiting for our internal request queue to
empty before proceeding. The internal request queue contains requests not
yet sent down to the controller.
We were clearing the requests queued for the LUN undergoing a reset, but
not all of the queued requests. Causing a hang.
For all requests in our internal request queue:
Complete requests with DID_RESET for queued requests for the device
undergoing a reset.
Complete requests with DID_REQUEUE for all other queued requests.

Add sysfs entry to check for write stream requests.
Move existing raid_bypass_cnt into a structure named pqi_raid_io_stats and
add member write_stream_cnt. These two counters are related because write
stream detection is only checked if an I/O request is eligible for bypass
(AIO).
Example usage:
lsscsi
[15:1:0:0] disk Adaptec LOGICAL VOLUME 0129 /dev/sdae
cat /sys/block/sdae/device/ssd_smart_path_enabled
1
^
|
+---- NOTE: here bypass has been enabled on device sdae
To read the counter for parity write stream requests:
cat /sys/block/sdae/device/write_stream_cnt
0x60cd507

Correct stream detection by initializing the structure
pqi_scsi_dev_raid_map_data to 0s.
When the OS issues SCSI READ commands, the driver erroneously considers
them as SCSI WRITES. If they are identified as sequential IOs, the driver
then submits those requests via the RAID path instead of the AIO path.
The 'is_write' flag might be set for SCSI READ commands also. The driver
may interpret SCSI READ commands as SCSI WRITE commands, resulting in IOs
being submitted through the RAID path.
Note: This does not cause data corruption.

Add controller logs to kdump.
Driver allocates DMA memory and communicates this address to FW. In the
event of system crash, host driver notifies the firmware about the crash
and firmware posts all the necessary logs in the pre-allocated host buffer
for firmware debugging.
Once firmware notifies the completion of the log uploading to the host
memory and host continues with the OS crash dump saving.
This is a "feature" driven capability and is backward compatible with
existing controller FW.
Rename some prefixes for OFA (Online-Firmware Activation ofa_*) buffers to
host_memory_*. So, not a lot of actual functional changes to
smartpqi_init.c, mainly determining the memory size allocation.
Added a function to notify the controller to copy debug data into host
memory before continuing kdump.
Most of the functional changes are in smartpqi_sis.c where the actual
handshaking is done.

The 'del_list_entry' field in "struct fc_port" is unused.
The field was introduced in commit 2d70c103fd2a ("[SCSI] qla2xxx: Add LLD
target-mode infrastructure for >= 24xx series") in 2012-05 and the last
user was removed in commit 726b85487067 ("qla2xxx: Add framework for async
fabric discovery") in 2017-02.
Remove this unused field.

Bart Van Assche <bvanassche@acm.org> says:
Hi Martin,
Multiple SCSI drivers use snprintf() to format a workqueue name before
invoking one of the create*_workqueue() macros. This patch series
simplifies such code by passing the format string and arguments to
alloc_workqueue(). Additionally, the structure members that are only
used as a temporary buffer for formatting workqueue names are
removed. Please consider this patch series for the next merge window.
Thanks,
Bart.

Let alloc_workqueue() format the workqueue name. Remove the
work_q_name[] member from struct Scsi_Host because it is no longer
used by any SCSI driver nor by the SCSI core.
