commit 3369046e54ca8f82e0cb17740643da2d80d3cfa8 upstream.
The SCSI debugfs code supports showing information about pending commands,
including translating SCSI command flags from numeric into text format.
Also convert the SCMD_LAST flag from numeric into text form.

[ Upstream commit 7dd2e2a923173d637c272e483966be8e96a72b64 ]
Extraneous teardown routines are present in the firmware dump path causing
altered states in firmware captures.
When a firmware dump is requested via sysfs, trigger the dump immediately
without tearing down structures and changing adapter state.
The driver shall rely on pre-existing firmware error state clean up
handlers to restore the adapter.

commit 142c779d05d1fef75134c3cb63f52ccbc96d9e1f upstream.
The PVSCSI implementation in the VMware hypervisor under specific
configuration ("SCSI Bus Sharing" set to "Physical") returns zero dataLen
in the completion descriptor for READ CAPACITY(16). As a result, the kernel
can not detect proper disk geometry. This can be recognized by the kernel
message:
[ 0.776588] sd 1:0:0:0: [sdb] Sector size 0 reported, assuming 512.
The PVSCSI implementation in QEMU does not set dataLen at all, keeping it
zeroed. This leads to a boot hang as was reported by Shmulik Ladkani.
It is likely that the controller returns the garbage at the end of the
buffer. Residual length should be set by the driver in that case. The SCSI
layer will erase corresponding data. See commit bdb2b8cab439 ("[SCSI] erase
invalid data returned by device") for details.
Commit e662502b3a78 ("scsi: vmw_pvscsi: Set correct residual data length")
introduced the issue by setting residual length unconditionally, causing
the SCSI layer to erase the useful payload beyond dataLen when this value
is returned as 0.
As a result, considering existing issues in implementations of PVSCSI
controllers, we do not want to call scsi_set_resid() when dataLen ==
0. Calling scsi_set_resid() has no effect if dataLen equals buffer length.

[ Upstream commit a0c2f8b6709a9a4af175497ca65f93804f57b248 ]
We can race where iscsi_session_recovery_timedout() has woken up the error
handler thread and it's now setting the devices to offline, and
session_recovery_timedout()'s call to scsi_target_unblock() is also trying
to set the device's state to transport-offline. We can then get a mix of
states.
For the case where we can't relogin we want the devices to be in
transport-offline so when we have repaired the connection
__iscsi_unblock_session() can set the state back to running.
Set the device state then call into libiscsi to wake up the error handler.

While looping over shost's sdev list it is possible that one
of the drives is getting removed and its sas_target object is
freed but its sdev object remains intact.
Consequently, a kernel panic can occur while the driver is trying to access
the sas_address field of sas_target object without also checking the
sas_target object for NULL.

[ Upstream commit 4edd8cd4e86dd3047e5294bbefcc0a08f66a430f ]
This fixes a regression added with:
commit f0f82e2476f6 ("scsi: core: Fix capacity set to zero after
offlinining device")
The problem is that after iSCSI recovery, iscsid will call into the kernel
to set the dev's state to running, and with that patch we now call
scsi_rescan_device() with the state_mutex held. If the SCSI error handler
thread is just starting to test the device in scsi_send_eh_cmnd() then it's
going to try to grab the state_mutex.
We are then stuck, because when scsi_rescan_device() tries to send its I/O
scsi_queue_rq() calls -> scsi_host_queue_ready() -> scsi_host_in_recovery()
which will return true (the host state is still in recovery) and I/O will
just be requeued. scsi_send_eh_cmnd() will then never be able to grab the
state_mutex to finish error handling.
To prevent the deadlock move the rescan-related code to after we drop the
state_mutex.
This also adds a check for if we are already in the running state. This
prevents extra scans and helps the iscsid case where if the transport class
has already onlined the device during its recovery process then we don't
need userspace to do it again plus possibly block that daemon.

[ Upstream commit 99154581b05c8fb22607afb7c3d66c1bace6aa5d ]
When parsing the txq list in lpfc_drain_txq(), the driver attempts to pass
the requests to the adapter. If such an attempt fails, a local "fail_msg"
string is set and a log message output. The job is then added to a
completions list for cancellation.
Processing of any further jobs from the txq list continues, but since
"fail_msg" remains set, jobs are added to the completions list regardless
of whether a wqe was passed to the adapter. If successfully added to
txcmplq, jobs are added to both lists resulting in list corruption.
Fix by clearing the fail_msg string after adding a job to the completions
list. This stops the subsequent jobs from being added to the completions
list unless they had an appropriate failure.

commit eeb1b55b6e25c5f7265ff45cd050f3bc2cc423a4 upstream.
When non-fatal error like line-reset happens, ufshcd_err_handler() starts
to abort tasks by ufshcd_try_to_abort_task(). When it tries to issue a task
management request, we hit two warnings:
WARNING: CPU: 7 PID: 7 at block/blk-core.c:630 blk_get_request+0x68/0x70
WARNING: CPU: 4 PID: 157 at block/blk-mq-tag.c:82 blk_mq_get_tag+0x438/0x46c
After fixing the above warnings we hit another tm_cmd timeout which may be
caused by unstable controller state:
__ufshcd_issue_tm_cmd: task management cmd 0x80 timed-out
Then, ufshcd_err_handler() enters full reset, and kernel gets stuck. It
turned out ufshcd_print_trs() printed too many messages on console which
requires CPU locks. Likewise hba->silence_err_logs, we need to avoid too
verbose messages. This is actually not an error case.

[ Upstream commit 4a8f71014b4d56c4fb287607e844c0a9f68f46d9 ]
The sgl is freed in the target stack in target_release_cmd_kref() before
calling qlt_free_cmd() but there is an unmap of sgl in qlt_free_cmd() that
causes a panic if sgl is not yet DMA unmapped:

The sgl may be left unmapped in error cases of response sending. For
instance, qlt_rdy_to_xfer() maps sgl and exits when session is being
deleted keeping the sgl mapped.
This patch removes use-after-free of the sgl and ensures that the sgl is
unmapped for any command that was not sent to firmware.

commit f2b85040acec9a928b4eb1b57a989324e8e38d3f upstream.
SCSI host release is triggered when SCSI device is freed. We have to make
sure that the low-level device driver module won't be unloaded before SCSI
host instance is released because shost->hostt is required in the release
handler.
Make sure to put LLD module refcnt after SCSI device is released.
Fixes a kernel panic of 'BUG: unable to handle page fault for address'
reported by Changhui and Yi.

commit 50b6cb3516365cb69753b006be2b61c966b70588 upstream.
After commit ea2f0f77538c ("scsi: core: Cap scsi_host cmd_per_lun at
can_queue"), a 416-CPU VM running on Hyper-V hangs during boot because the
hv_storvsc driver sets scsi_driver.can_queue to an integer value that
exceeds SHRT_MAX, and hence scsi_add_host_with_dma() sets
shost->cmd_per_lun to a negative "short" value.
Use min_t(int, ...) to work around the issue.

[ Upstream commit 79a7482249a7353bc86aff8127954d5febf02472 ]
Both cxgb4 and csiostor drivers run on their own independent Physical
Function. But when cxgb4 and csiostor are both being loaded in parallel via
modprobe, there is a race when firmware upgrade is attempted by both the
drivers.
When the cxgb4 driver initiates the firmware upgrade, it halts the firmware
and the chip until upgrade is complete. When the csiostor driver is coming
up in parallel, the firmware mailbox communication fails with timeouts and
the csiostor driver probe fails.
Add a module soft dependency on cxgb4 driver to ensure loading csiostor
triggers cxgb4 to load first when available to avoid the firmware upgrade
race.

commit c8fadf019964d0eb1da410ba8b629494d3339db9 upstream.
The first invocation of function find_first_zero_bit will return 0 and
queue_id gets set to 0.
An index of queue_pair_map also gets set to 0.
qpair_id = find_first_zero_bit(ha->qpair_qid_map, ha->max_qpairs);
set_bit(qpair_id, ha->qpair_qid_map);
ha->queue_pair_map[qpair_id] = qpair;
In the alloc_queue callback driver checks the map, if queue is already
allocated:
ha->queue_pair_map[qidx]
This works fine as long as max_qpairs is greater than nvme_max_hw_queues(8)
since the size of the queue_pair_map is equal to max_qpair. In case nr_cpus
is less than 8, max_qpairs is less than 8. This creates wrong value
returned as qpair.

commit 44d01fc86d952f5a8b8b32bdb4841504d5833d95 upstream.
Update BusLogic driver's messaging system to use pr_cont() for continuation
lines, bringing messy output:

Also diagnostic output such as with the BusLogic=TraceConfiguration
parameter is affected and becomes vertical and therefore hard to read.
This has now been corrected, e.g.:
