The driver retries certain register reads 3 times if the returned value is
0. This was done because the controller could return 0 for certain
registers if other registers were being accessed concurrently by the BMC.
In certain systems with increased BMC interactions, the register values
returned can be 0 for longer than 3 retries. Change the retry count from 3
to 30 for the affected registers to prevent problems with out-of-band
management.

sgreset is issued with a SCSI command pointer. The device reset code
assumes that it was issued on a hardware queue, and calls block multiqueue
layer. However, the assumption is broken, and there is no hardware queue
associated with the sgreset, and this leads to a crash due to a null
pointer exception.
Fix the code to use the max_tag_id as a tag which does not overlap with the
other tags issued by mid layer.
Tested by running FC traffic for a few minutes, and by issuing sgreset on
the device in parallel. Without the fix, the crash is observed right away.
With this fix, no crash is observed.

Testing of virtual Fibre Channel devices under Hyper-V has shown additional
SRB status values being returned for various error cases. Because these
SRB status values are not recognized by storvsc, the I/O operations are not
flagged as an error. Requests are treated as if they completed normally but
with zero data transferred, which can cause a flood of retries.
Add definitions for these SRB status values and handle them like other
error statuses from the Hyper-V host.

These patches are based on Martin Petersen's 6.6/scsi-queue tree
https://git.kernel.org/pub/scm/linux/kernel/git/mkp/scsi.git
6.6/scsi-queue
The biggest functional change to smartpqi is the addition of an abort
handler. Some customers were complaining about I/O stalls to all
devices when only one device is reset. Adding an abort handler helps
to prevent I/O stalls to all devices.
All of the reset of the patches are small changes to logging messages,
MACRO and variable name changes, and one minor change for LUN
assignments.
This set of changes consists of:
* smartpqi-add-abort-handler
When a device reset occurs, the SML pauses I/O to all devices presented
by a controller instance causing some performance issues.
To only affect device with a problematic request, we added an abort handler.
The abort handler is implemented by using a device reset, but I/O to the
other devices is no longer affected.
* smartpqi-refactor-rename-MACRO-to-clarify-purpose
The MACRO SOP_RC_INCORRECT_LOGICAL_UNIT was used to check for a condition
where a TMF was sent an incorrect LUN. We renamed this MACRO to
SOP_TMF_INCORRECT_LOGICAL_UNIT for clarity.
* smartpqi-refactor-rename-pciinfo-to-pci_info
Change the pciinfo variable to pci_info to make more readable code.
No functional changes.
* smartpqi-simplify-lun_number-assignment
We simplified the conditional expression used to populate LUN numbers
for requests.
* smartpqi-enhance-shutdown-notification
Clarify controller cache flush errors. We added in more precise information
to the cache flush informational message.
No functional changes.
* smartpqi-enhance-controller-offline-notification
The driver can offline a controller for multiple reasons. We added
a description of why these rare offline actions are taken. And a function
to provide the specific details of the shutdown.
* smartpqi-enhance-error-messages
We added host🚌target:lun to messages emitted in our reset/abort handlers.
No functional changes.
* smartpqi-change-driver-version-to-2.1.24-046

Commit 41320b18a0 ("scsi: snic: Fix possible memory leak if device_add()

failed. However, it did not consider that 'tgt' has already been released
when put_device(&tgt->dev) is called. Remove kfree(tgt) in the error path
to avoid double free of 'tgt' and move put_device(&tgt->dev) after the
removed kfree(tgt) to avoid a use-after-free.

Many tape devices will automatically rewind following a poweron/reset.
This can result in data loss as other operations in the driver can write to
the tape when the position is unknown. E.g. MTEOM can write a filemark at
the beginning of the tape. This patch adds code to detect poweron/reset
unit attentions and prevents the driver from writing to the tape when the
position could be unknown.
Customer reported problem description:
We have experienced an issue with the SCSI tape driver (st) which has led
to data loss for us on two separate occasions in production, as well as in
a third case in which we were able to reproduce the failure in our test
environment.
The tape device involved is an Amazon Tape Gateway, a virtual tape library
(VTL) appliance which presents as a series of iSCSI targets (multiple tape
drives and a changer) and is backed by storage in Amazon S3. The problem is
a general one and not limited to any particular SCSI transport or tape
device, though the nature of both iSCSI and the VTL make data loss somewhat
more likely with this combination than with a physical tape drive.
The observed behavior occurs when an error causes the VTL tape gateway
process (on the appliance) to crash and restart. This interrupts the iSCSI
TCP connections and, when it occurs during a write, causes the write to
fail with EIO. However, we then find that the virtual tape in question is
now completely blank. We raised this issue with AWS support, thinking this
must be a bug in the VTL appliance, but that turns out not to be the case.
Per AWS support, when the gateway crashes in this manner, its notion of the
current tape position is reset to the beginning of the tape. It also sets a
unit attention condition, such that the next request results in a CHECK
CONDITION status with sense key UNIT ATTENTION and asc/ascq indicating a
device reset. According to their logs the next command being sent is WRITE
FILEMARK, which results in writing an FM at the beginning of the tape,
effectively discarding its contents.
In fact, once the write fails with EIO, our software attempts to recover by
rewinding and repositioning the tape, then resuming operation. If this
fails, it attempts to rewind and reposition again, write a marker at the
end of the tape, and then unmount. It does not under any circumstances
write either data or filemarks without having successfully positioned the
tape to a known point.
What actually happens is that, since the last operation was a write, the
kernel executes an implied MTWEOF operation (which translate to a Write
Filemarks command) before the rewind that was actually requested. This
seems not entirely unreasonable, provided the tape position is known.
However, once this request fails (due to the unit attention condition), our
next rewind attempt also triggers an implied MTWEOF, which does _not_ fail
(the unit attention condition persists only until the initiator has been
notified); this is the command that unexpectedly erases the tape.
Our analysis is that the st driver is in fact completely ignoring the UNIT
ATTENTION and associated reset notification from the device. This is not a
condition that can be detected in the transport or mid-layer, as it occurs
entirely within the target and is reported only via the UNIT ATTENTION
sense key. The upper driver (i.e. st) needs to detect this indication and
reset its internal model of the device to an unknown state.

For Command Duration Limits policy 0xD (command completes without an
error) libata needs FIS in order to detect the ATA_SENSE bit and read
the Sense Data for Successful NCQ Commands log (0Fh). pm80xx HBAs do
not return FIS on success by default, hence, the driver is updated to
set the RETFIS bit (Return FIS on good completion) when requested by
libsas.
