cc28fac16a scsi: lpfc: Fix split code for FLOGI on FCoE
The refactoring code converted context information from SLI-3 to SLI-4.
The conversion for the SLI-4 bit field tried to use the old (hacky) SLI3
high/low bit settings.  Needless to say, it was incorrect.

Explicitly set the context field to type FCFI and set it in the wqe.
SLI-4 is now a proper bit field so no need for the shifting/anding.

26f9ce5381 scsi: qla2xxx: Fix missed DMA unmap for aborted commands
Aborting commands that have already been sent to the firmware can
cause BUG in qlt_free_cmd(): BUG_ON(cmd->sg_mapped)

For instance:

 - Command passes rdx_to_xfer state, maps sgl, sends to the firmware

 - Reset occurs, qla2xxx performs ISP error recovery, aborts the command

 - Target stack calls qlt_abort_cmd() and then qlt_free_cmd()

 - BUG_ON(cmd->sg_mapped) in qlt_free_cmd() occurs because sgl was not
   unmapped

Thus, unmap sgl in qlt_abort_cmd() for commands with the aborted flag set.

6056a92ceb scsi: scsi_dh_alua: Properly handle the ALUA transitioning state
The handling of the ALUA transitioning state is currently broken. When a
target goes into this state, it is expected that the target is allowed to
stay in this state for the implicit transition timeout without a path
failure. The handler has this logic, but it gets skipped currently.

When the target transitions, there is in-flight I/O from the initiator. The
first of these responses from the target will be a unit attention letting
the initiator know that the ALUA state has changed.  The remaining
in-flight I/Os, before the initiator finds out that the portal state has
changed, will return not ready, ALUA state is transitioning. The portal
state will change to SCSI_ACCESS_STATE_TRANSITIONING. This will lead to all
new I/O immediately failing the path unexpectedly. The path failure happens
in less than a second instead of the expected successes until the
transition timer is exceeded.

Allow I/Os to continue while the path is in the ALUA transitioning
state. The handler already takes care of a target that stays in the
transitioning state for too long by changing the state to ALUA state
standby once the transition timeout is exceeded at which point the path
will fail.

8be70a842f scsi: target: pscsi: Set SCF_TREAT_READ_AS_NORMAL flag only if there is valid data
With tape devices, the SCF_TREAT_READ_AS_NORMAL flag is used by the target
subsystem to mark commands which have both data to return as well as sense
data. But with pscsi, SCF_TREAT_READ_AS_NORMAL can be set even if there is
no data to return. The SCF_TREAT_READ_AS_NORMAL flag causes the target core
to call iscsit data-in callbacks even if there is no data, which iscsit
does not support. This results in iscsit going into an error state
requiring recovery and being unable to complete the command to the
initiator.

This issue can be resolved by fixing pscsi to only set
SCF_TREAT_READ_AS_NORMAL if there is valid data to return alongside the
sense data.

faad6cebde scsi: sr: Do not leak information in ioctl
sr_ioctl.c uses this pattern:

  result = sr_do_ioctl(cd, &cgc);

Use of a buffer without checking leaks information. Check result and jump
over the use of buffer if there is an error.

  result = sr_do_ioctl(cd, &cgc);
  if (result)
    goto err;
  to-user = buffer[];
err:
  kfree(buffer);

Additionally, initialize the buffer to zero.

This problem can be seen in the 2.4.0 kernel.

857b06527f scsi: qedi: Fix failed disconnect handling
We set the qedi_ep state to EP_STATE_OFLDCONN_START when the ep is
created. Then in qedi_set_path we kick off the offload work. If userspace
times out the connection and calls ep_disconnect, qedi will only flush the
offload work if the qedi_ep state has transitioned away from
EP_STATE_OFLDCONN_START. If we can't connect we will not have transitioned
state and will leave the offload work running, and we will free the qedi_ep
from under it.

This patch just has us init the work when we create the ep, then always
flush it.

03690d8197 scsi: iscsi: Fix unbound endpoint error handling
If a driver raises a connection error before the connection is bound, we
can leave a cleanup_work queued that can later run and disconnect/stop a
connection that is logged in. The problem is that drivers can call
iscsi_conn_error_event for endpoints that are connected but not yet bound
when something like the network port they are using is brought down.
iscsi_cleanup_conn_work_fn will check for this and exit early, but if the
cleanup_work is stuck behind other works, it might not get run until after
userspace has done ep_disconnect. Because the endpoint is not yet bound
there was no way for ep_disconnect to flush the work.

The bug of leaving stop_conns queued was added in:

Commit 23d6fefbb3 ("scsi: iscsi: Fix in-kernel conn failure handling")

and:

Commit 0ab710458d ("scsi: iscsi: Perform connection failure entirely in
kernel space")

was supposed to fix it, but left this case.

This patch moves the conn state check to before we even queue the work so
we can avoid queueing.

7c6e99c181 scsi: iscsi: Fix conn cleanup and stop race during iscsid restart
If iscsid is doing a stop_conn at the same time the kernel is starting
error recovery we can hit a race that allows the cleanup work to run on a
valid connection. In the race, iscsi_if_stop_conn sees the cleanup bit set,
but it calls flush_work on the clean_work before iscsi_conn_error_event has
queued it. The flush then returns before the queueing and so the
cleanup_work can run later and disconnect/stop a conn while it's in a
connected state.

The patch:

Commit 0ab710458d ("scsi: iscsi: Perform connection failure entirely in
kernel space")

added the late stop_conn call bug originally, and the patch:

Commit 23d6fefbb3 ("scsi: iscsi: Fix in-kernel conn failure handling")

attempted to fix it but only fixed the normal EH case and left the above
race for the iscsid restart case. For the normal EH case we don't hit the
race because we only signal userspace to start recovery after we have done
the queueing, so the flush will always catch the queued work or see it
completed.

For iscsid restart cases like boot, we can hit the race because iscsid will
call down to the kernel before the kernel has signaled any error, so both
code paths can be running at the same time. This adds a lock around the
setting of the cleanup bit and queueing so they happen together.

0aadafb5c3 scsi: iscsi: Fix endpoint reuse regression
This patch fixes a bug where when using iSCSI offload we can free an
endpoint while userspace still thinks it's active. That then causes the
endpoint ID to be reused for a new connection's endpoint while userspace
still thinks the ID is for the original connection. Userspace will then end
up disconnecting a running connection's endpoint or trying to bind to
another connection's endpoint.

This bug is a regression added in:

Commit 23d6fefbb3 ("scsi: iscsi: Fix in-kernel conn failure handling")

where we added a in kernel ep_disconnect call to fix a bug in:

Commit 0ab710458d ("scsi: iscsi: Perform connection failure entirely in
kernel space")

where we would call stop_conn without having done ep_disconnect. This early
ep_disconnect call will then free the endpoint and it's ID while userspace
still thinks the ID is valid.

Fix the early release of the ID by having the in kernel recovery code keep
a reference to the endpoint until userspace has called into the kernel to
finish cleaning up the endpoint/connection. It requires the previous commit
"scsi: iscsi: Release endpoint ID when its freed" which moved the freeing
of the ID until when the endpoint is released.

cbd2283aaf scsi: iscsi: Fix offload conn cleanup when iscsid restarts
When userspace restarts during boot or upgrades it won't know about the
offload driver's endpoint and connection mappings. iscsid will start by
cleaning up the old session by doing a stop_conn call. Later, if we are
able to create a new connection, we clean up the old endpoint during the
binding stage. The problem is that if we do stop_conn before doing the
ep_disconnect call offload, drivers can still be executing I/O. We then
might free tasks from the under the card/driver.

This moves the ep_disconnect call to before we do the stop_conn call for
this case. It will then work and look like a normal recovery/cleanup
procedure from the driver's point of view.

- Make the prctl() for enabling dynamic XSTATE components correct so it
     adds the newly requested feature to the permission bitmap instead of
     overwriting it. Add a selftest which validates that.
 
   - Unroll string MMIO for encrypted SEV guests as the hypervisor cannot
     emulate it.
 
   - Handle supervisor states correctly in the FPU/XSTATE code so it takes
     the feature set of the fpstate buffer into account. The feature sets
     can differ between host and guest buffers. Guest buffers do not contain
     supervisor states. So far this was not an issue, but with enabling
     PASID it needs to be handled in the buffer offset calculation and in
     the permission bitmaps.
 
   - Avoid a gazillion of repeated CPUID invocations in by caching the values

theme is that orphan clks are having rates set on them when that isn't
expected. Let's revert it out for now so that -rc1 boots.

1cd927ad6f tracing: mark user_events as BROKEN
After being merged, user_events become more visible to a wider audience
that have concerns with the current API.

It is too late to fix this for this release, but instead of a full
revert, just mark it as BROKEN (which prevents it from being selected in
make config).  Then we can work finding a better API.  If that fails,
then it will need to be completely reverted.

To not have the code silently bitrot, still allow building it with
COMPILE_TEST.

And to prevent the uapi header from being installed, then later changed,
and then have an old distro user space see the old version, move the
header file out of the uapi directory.

Surround the include with CONFIG_COMPILE_TEST to the current location,
but when the BROKEN tag is taken off, it will use the uapi directory,
and fail to compile.  This is a good way to remind us to move the header
back.

5cfff569ca tracing: Move user_events.h temporarily out of include/uapi
While user_events API is under development and has been marked for broken
to not let the API become fixed, move the header file out of the uapi
directory. This is to prevent it from being installed, then later changed,
and then have an old distro user space update with a new kernel, where
applications see the user_events being available, but the old header is in
place, and then they get compiled incorrectly.

Also, surround the include with CONFIG_COMPILE_TEST to the current
location, but when the BROKEN tag is taken off, it will use the uapi
directory, and fail to compile. This is a good way to remind us to move
the header back.
