Pull SCSI updates from James Bottomley:
"Updates to the usual drivers (qla2xxx, lpfc, ufs, hisi_sas, mpi3mr,
mpt3sas, target). The biggest change (from my biased viewpoint) being
that the mpi3mr now attached to the SAS transport class, making it the
first fusion type device to do so.
Beyond the usual bug fixing and security class reworks, there aren't a
huge number of core changes"

DID_TARGET_FAILURE is internal to the SCSI layer. Drivers must not use it
because:
1. It's not propagated upwards, so SG IO/passthrough users will not see an
error and think a command was successful.
2. There is no handling for it in scsi_decide_disposition() so it
results in entering SCSI error handling.
This has qla2xxx use DID_NO_CONNECT because it looks like we hit this error
when we can't find a port. It will give us the same hard error behavior and
it seems to match the error where we can't find the endpoint.

Older tracing of driver messages was to:
- log only debug messages to kernel main trace buffer; and
- log only if extended logging bits corresponding to this message is
off
This has been modified and extended as follows:
- Tracing is now controlled via ql2xextended_error_logging_ktrace
module parameter. Bit usages same as ql2xextended_error_logging.
- Tracing uses "qla2xxx" trace instance, unless instance creation have
issues.
- Tracing is enabled (compile time tunable).
- All driver messages, include debug and log messages are now traced in
kernel trace buffer.
Trace messages can be viewed by looking at the qla2xxx instance at:
/sys/kernel/tracing/instances/qla2xxx/trace
Trace tunable that takes the same bit mask as ql2xextended_error_logging
is:
ql2xextended_error_logging_ktrace (default=1)

This message is helpful to troubleshoot missing LUNs/SAN boot errors. It'd
be nice to log it by default instead of only being enabled with debug.
This user had an accidental/forgotten file modprobe.d/qla2xxx.conf w/
option qlini_mode=disabled from experiments with FC target mode, and their
boot LUN didn't come up, as it skips SCSI scan, of course.
However, their boot log didn't provide any clues to help understand that.
The issue/message could be figured out w/ ql2xextended_error_logging, but
it would have been simpler (or even deflected/addressed by user) if it had
been there by default. And it also would help support/triage/deflection
tooling.

This partially reverts commit d2b292c3f6 ("scsi: qla2xxx: Enable ATIO
interrupt handshake for ISP27XX")
For some workloads where the host sends a batch of commands and then
pauses, ATIO interrupt coalesce can cause some incoming ATIO entries to be
ignored for extended periods of time, resulting in slow performance,
timeouts, and aborted commands.
Disable interrupt coalesce and re-enable the dedicated ATIO MSI-X
interrupt.

On some platforms, the current logic of relying on finding new packet
solely based on signature pattern can lead to driver reading stale
packets. Though this is a bug in those platforms, reduce such exposures by
limiting reading packets until the IN pointer.
Two module parameters are introduced:
ql2xrspq_follow_inptr:
When set, on newer adapters that has queue pointer shadowing, look for
response packets only until response queue in pointer.
When reset, response packets are read based on a signature pattern
logic (old way).
ql2xrspq_follow_inptr_legacy:
Like ql2xrspq_follow_inptr, but for those adapters where there is no
queue pointer shadowing.

User experience slow recovery when target device went through a stop/start
of the authentication application (app_stop/app_start).
Between the period of app_stop and app_start on the target device, target
device choose to send ELS Reject for any receive AUTH ELS command. At this
time, authentication application does not do ELS reject if it encounters
error.
Therefore, AUTH ELS reject signify authentication application is not
running. If driver passes up the AUTH ELS Reject to the authentication
application, then it would result in authentication application
retrying/resending the same AUTH ELS command again + delay.
As a work around, driver should trigger a session tear down where it tells
the local authentication application to also tear down. At the next
relogin, both sides are then synchronized.

The scenario is this: User loaded driver but has not started authentication
app. All sessions to secure device will exhaust all login attempts, fail,
and in stay in deleted state. Then some time later the app is started. The
driver will replenish the login retry count, trigger delete to prepare for
secure login. After deletion, relogin is triggered.
For the session that is already deleted, the delete trigger is a no-op. If
none of the sessions trigger a relogin, no progress is made.
Add a relogin trigger.
