531643fcd9 SCSI fixes on 20241019
Fixes all in drivers. The largest is the mpi3mr which corrects a phy
 count limit that should only apply to the controller but was being
 incorrectly applied to expander phys.

b9e63d6c7c scsi: mpi3mr: Validate SAS port assignments
A sanity check on phy_mask was added in commit 3668651def ("scsi:
mpi3mr: Sanitise num_phys"). This causes warning messages when more than
64 phys are detected and devices connected to phys greater than 64 are
dropped.

The phy_mask bitmap is only needed for controller phys and not required
for expander phys. Controller phys can go up to a maximum of 64 and
therefore u64 is good enough to contain phy_mask bitmap.

To suppress those warnings and allow devices to be discovered as before
the offending commit, restrict the phy_mask setting and lowest phy
setting only to the controller phys.

Fixes: 3668651def ("scsi: mpi3mr: Sanitise num_phys")

9023ed8d91 scsi: wd33c93: Don't use stale scsi_pointer value
A regression was introduced with commit dbb2da557a ("scsi: wd33c93:
Move the SCSI pointer to private command data") which results in an oops
in wd33c93_intr(). That commit added the scsi_pointer variable and
initialized it from hostdata->connected. However, during selection,
hostdata->connected is not yet valid. Fix this by getting the current
scsi_pointer from hostdata->selecting.

f30e5f77d2 scsi: fnic: Move flush_work initialization out of if block
After commit 379a58caa1 ("scsi: fnic: Move fnic_fnic_flush_tx() to a
work queue"), it can happen that a work item is sent to an uninitialized
work queue.  This may has the effect that the item being queued is never
actually queued, and any further actions depending on it will not
proceed.

The following warning is observed while the fnic driver is loaded:

kernel: WARNING: CPU: 11 PID: 0 at ../kernel/workqueue.c:1524 __queue_work+0x373/0x410
kernel:  <IRQ>

kernel:  handle_edge_irq+0x7e/0x1a0
kernel:  __common_interrupt+0x3b/0xb0
kernel:  common_interrupt+0x58/0xa0
kernel:  </IRQ>

It has been observed that this may break the rediscovery of Fibre
Channel devices after a temporary fabric failure.

This patch fixes it by moving the work queue initialization out of
an if block in fnic_probe().

cb787f4ac0 [tree-wide] finally take no_llseek out
no_llseek had been defined to NULL two years ago, in commit 868941b144
("fs: remove no_llseek")

To quote that commit,

  At -rc1 we'll need do a mechanical removal of no_llseek -

  git grep -l -w no_llseek | grep -v porting.rst | while read i; do
	sed -i '/\<no_llseek\>/d' $i
  done

  would do it.

Unfortunately, that hadn't been done.  Linus, could you do that now, so
that we could finally put that thing to rest? All instances are of the
form
	.llseek = no_llseek,
so it's obviously safe.

benefit is that events of interest are still logged and the entire trace

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

d1a2ef63fc scsi: lpfc: Fix kref imbalance on fabric ndlps from dev_loss_tmo handler
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.

93bcc5f398 scsi: lpfc: Add ELS_RSP cmd to the list of WQEs to flush in lpfc_els_flush_cmd()
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

4708c9332d scsi: pmcraid: Convert comma to semicolon
Replace comma between expressions with semicolons.

Using a ',' in place of a ';' can have unintended side effects. Although
that is not the case here, it is seems best to use ';' unless ',' is
intended.

Found by inspection. No functional change intended. Compile tested only.

a8598aefae scsi: sd: Retry START STOP UNIT commands
During system resume, sd_start_stop_device() submits a START STOP UNIT
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:

[16575.983359] sd 0:0:0:3: [sdd] Starting disk
[16575.983693] sd 0:0:0:3: [sdd] Start/Stop Unit failed: Result: hostbyte=0x00 driverbyte=DRIVER_OK
[16575.983712] sd 0:0:0:3: [sdd] Sense Key : 0x6
[16575.983730] sd 0:0:0:3: [sdd] ASC=0x29 ASCQ=0x0
[16575.983738] sd 0:0:0:3: PM: dpm_run_callback(): scsi_bus_resume+0x0/0xa0 returns -5
[16575.983783] sd 0:0:0:3: PM: failed to resume async: error -5

Make the SCSI core retry the START STOP UNIT command if the device reports
that it has been powered on or that it has been reset.

24d7071d96 scsi: mpi3mr: A performance fix
Commit 0c52310f26 ("hrtimer: Ignore slack time for RT tasks in
schedule_hrtimeout_range()") effectivelly shortens a sleep in a polling
function in the driver.  That is causing a performance regression as the
new value of just 2us is too low, in certain tests the perf drop is ~30%.
Fix this by adjusting the sleep to 20us (close to the previous value).

e368400694 scsi: ibmvfc: Add max_sectors module parameter
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.

[mkp: fix checkpatch warnings]

3d882cca73 scsi: st: Fix input/output error on empty drive reset
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 9604eea5bd ("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.
