Fix referencing sense data when it is invalid. When the length of the data
segment is 0, there is no valid information in the rsp field, so
ufshpb_rsp_upiu() is returned without additional operation.

In commit d72d827f2f26, I used 'cpumask_t' incorrectly:
void iscsit_thread_get_cpumask(struct iscsi_conn *conn)
{
int ord, cpu;
cpumask_t conn_allowed_cpumask;
......
}
static ssize_t lio_target_wwn_cpus_allowed_list_store(
struct config_item *item, const char *page, size_t count)
{
int ret;
char *orig;
cpumask_t new_allowed_cpumask;
......
}
The correct pattern should be as follows:
cpumask_var_t mask;
if (!zalloc_cpumask_var(&mask, GFP_KERNEL))
return -ENOMEM;
... use 'mask' here ...
free_cpumask_var(mask);

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.

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.

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.

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.

sr_ioctl.c uses this pattern:
result = sr_do_ioctl(cd, &cgc);
to-user = buffer[];
kfree(buffer);
return result;
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);
return result;
Additionally, initialize the buffer to zero.
This problem can be seen in the 2.4.0 kernel.

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.

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 23d6fefbb3f6 ("scsi: iscsi: Fix in-kernel conn failure handling")
and:
Commit 0ab710458da1 ("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.

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 0ab710458da1 ("scsi: iscsi: Perform connection failure entirely in
kernel space")
added the late stop_conn call bug originally, and the patch:
Commit 23d6fefbb3f6 ("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.

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 23d6fefbb3f6 ("scsi: iscsi: Fix in-kernel conn failure handling")
where we added a in kernel ep_disconnect call to fix a bug in:
Commit 0ab710458da1 ("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.

We can't release the endpoint ID until all references to the endpoint have
been dropped or it could be allocated while in use. This has us use an idr
instead of looping over all conns to find a free ID and then free the ID
when all references have been dropped instead of when the device is only
deleted.

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.

MSGU_ODMR_CLR_U(0x3C) to unmask the interrupts. In these registers bit 0-31
represents interrupt vectors 32-63.

This driver doesn't use SCp.ptr to save a SCSI command data pointer which
means "scsi pointer" is a complete misnomer here. Only a few members of
struct scsi_pointer are needed so move those to private command data.

Expanded testing of DM's bio polling support (using more fio threads
to dm-linear ontop of null_blk) exposed the possibility for polled
bios to hang (repeatedly polling in io_uring) when null_blk responds
with BLK_STS_AGAIN (due to lack of resources):
1) io_complete_rw_iopoll() is called from blkdev_bio_end_io_async() to
notify kiocb is done, that is the completion interface between block
layer and io_uring
2) io_complete_rw_iopoll() is called from io_do_iopoll()
3) dm returns BLK_STS_AGAIN for one bio (on behalf of underlying
driver), then io_complete_rw_iopoll is called, but io_do_iopoll()
doesn't handle -EAGAIN at all (due to logic in io_rw_should_reissue)
4) reason for dm's BLK_STS_AGAIN is underlying null_blk driver ran out
of requests (easier to reproduce by setting low hw_queue_depth).
5) dm should handle BLK_STS_AGAIN for POLLED underlying IO, and may
retry in dm layer.
This fix adds REQ_POLLED specific BLK_STS_AGAIN handling to
dm_io_complete() that clears REQ_POLLED and requeues the bio to DM
using queue_io().

Early alpha processors cannot write a single byte or short; they read 8
bytes, modify the value in registers and write back 8 bytes.
This could cause race condition in the structure dm_io - if the fields
flags and io_count are modified simultaneously.

compiling for a processor that doesn't have the byte-word-extension.

Commit f6f72f32c22c ("dm integrity: don't replay journal data past the
end of the device") skips journal replay if the target sector points
beyond the end of the device. Unfortunatelly, it doesn't set the
journal entry unused, which resulted in this BUG being triggered:
BUG_ON(!journal_entry_is_unused(je))
Fix this by calling journal_entry_set_unused() for this case.

This reverts commit 37ef4c19b4c659926ce65a7ac709ceaefb211c40.
The touchpad present in the Dell Precision 7550 and 7750 laptops
reports a HID_DG_BUTTONTYPE of type MT_BUTTONTYPE_CLICKPAD. However,
the device is not a clickpad, it is a touchpad with physical buttons.
In order to fix this issue, a quirk for the device was introduced in
libinput [1] [2] to disable the INPUT_PROP_BUTTONPAD property:
[Precision 7x50 Touchpad]
MatchBus=i2c
MatchUdevType=touchpad
MatchDMIModalias=dmi:*svnDellInc.:pnPrecision7?50*
AttrInputPropDisable=INPUT_PROP_BUTTONPAD
However, because of the change introduced in 37ef4c19b4 ("Input: clear
BTN_RIGHT/MIDDLE on buttonpads") the BTN_RIGHT key bit is not mapped
anymore breaking the device right click button and making impossible to
workaround it in user space.
In order to avoid breakage on other present or future devices, revert
the patch causing the issue.
