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.

cat smartpqi_6.6_cover_letter
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:bus:target:lun to messages emitted in our reset/abort handlers.
   No functional changes.
 * smartpqi-change-driver-version-to-2.1.24-046

Commit 41320b18 ("scsi: snic: Fix possible memory leak if device_add()
fails") fixed the memory leak caused by dev_set_name() when 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.

Most callers of scsi_rescan_device() have the scsi_device pointer readily
available. Pass a struct scsi_device pointer to scsi_rescan_device()
instead of a struct device pointer. This change prevents that a pointer to
another struct device would be passed accidentally to scsi_rescan_device().

Remove the scsi_rescan_device() declaration from the scsi_priv.h header
file since it duplicates the declaration in <scsi/scsi_host.h>.

enum sas_class prob would have been useful if function sas_show_class() was
ever implemented, which it wasn't.

enum sas_class is used as asd_sas_port.class and asd_sas_phy.class, which
are only ever set, so delete these members and the enum.

Since libsas was introduced in commit 2908d778

 ("[SCSI] aic94xx: new
driver"), sas_ha_struct.lldd_module has only ever been set, so remove it.

Struct scsi_host_template already has a reference to the LLD driver
module as to stop the driver being removed unexpectedly.

User accidently passed module parameter ql2xenabledif=1 which is
unsupported. However, driver still initialized which lead to guard tag
errors during device discovery.

Remove unsupported ql2xenabledif=1 option and validate the user input.
