When a port sends PLOGI, discovery state should be changed to login
pending, otherwise RELOGIN_NEEDED bit is set in
qla24xx_handle_plogi_done_event(). RELOGIN_NEEDED triggers another PLOGI,
and it never goes out of the loop until login timer expires.

The crash can be triggered by ACL deletion when there's active I/O.
During ACL deletion, qla2xxx performs implicit LOGO that's invisible for
the initiator. Only the driver and firmware are aware of the logout.
Therefore the initiator continues to send SCSI commands and the target
always responds with SAM STATUS BUSY as it can't find the session.
The command times out after a while and initiator invokes ABORT TASK TMF
for the command. The TMF is mapped to ABTS-LS in FCP. The target can't find
session for S_ID originating ABTS-LS so it never allocates mcmd. And since
N_Port handle was deleted after LOGO, it is no longer valid and ABTS
Response IOCB is returned from firmware with status 31. Then free_mcmd is
invoked on NULL pointer and the kernel crashes.

commit f45bca8c5052e8c59bab64ee90c44441678b9a52 upstream.
Current code assumes abort will remove the original command from the active
list where scsi_done will not be called. Instead, the eh_abort thread will
do the scsi_done. That is not the case. Instead, we have a double
scsi_done calls triggering use after free.
Abort will tell FW to release the command from FW possesion. The original
command will return to ULP with error in its normal fashion via scsi_done.
eh_abort path would wait for the original command completion before
returning. eh_abort path will not perform the scsi_done call.

commit 324e1c402069e8d277d2a2b18ce40bde1265b96a upstream.
In cases where I/O may be aborted, such as driver unload or link bounces,
the system will crash based on a bad ndlp pointer.
Example:
RIP: 0010:lpfc_sli4_abts_err_handler+0x15/0x140 [lpfc]
...
lpfc_sli4_io_xri_aborted+0x20d/0x270 [lpfc]

lpfc_sli4_fp_handle_cqe+0xc2/0x480 [lpfc]
__lpfc_sli4_process_cq+0xc6/0x230 [lpfc]
__lpfc_sli4_hba_process_cq+0x29/0xc0 [lpfc]
process_one_work+0x14c/0x390
Crash was caused by a bad ndlp address passed to I/O indicated by the XRI
aborted CQE. The address was not NULL so the routine deferenced the ndlp
ptr. The bad ndlp also caused the lpfc_sli4_io_xri_aborted to call an
erroneous io handler. Root cause for the bad ndlp was an lpfc_ncmd that
was aborted, put on the abort_io list, completed, taken off the abort_io
list, sent to lpfc_release_nvme_buf where it was put back on the abort_io
list because the lpfc_ncmd->flags setting LPFC_SBUF_XBUSY was not cleared
on the final completion.
Rework the exchange busy handling to ensure the flags are properly set for
both scsi and nvme.

In scsi_mq_setup_tags(), cmd_size is calculated based on zero size for the
scatter-gather list in case the low level driver uses SG_NONE in its host
template.
cmd_size is passed on to the block layer for calculation of the request
size, and we've seen NULL pointer dereference errors from the block layer
in drivers where SG_NONE is used and a mq IO scheduler is active,
apparently as a consequence of this (see commit 68ab2d76e4 ("scsi:
cxlflash: Set sg_tablesize to 1 instead of SG_NONE"), and a recent patch by
Finn Thain converting the three m68k NFR5380 drivers to avoid setting
SG_NONE).
Try to avoid these errors by accounting for at least one sg list entry when
calculating cmd_size, regardless of whether the low level driver set a zero
sg_tablesize.
Tested on 030 m68k with the atari_scsi driver - setting sg_tablesize to
SG_NONE no longer results in a crash when loading this driver.

Variable dif in function sd_setup_read_write_cmnd() is the return value of
function scsi_host_dif_capable() which returns dif capability of disks. If
define it as bool, even for the disks which support DIF3, the function
still return dif=1, which causes IO error. So define variable dif as
unsigned int instead of bool.

The scsi async probe process is calling blk_pm_runtime_init for each lun,
and then those request queues are monitored by the block layer pm
engine (blk-pm.c). This is however, not the case for scsi-passthrough
queues, created by bsg_setup_queue().
So the ufs-bsg driver might send various commands, disregarding the pm
status of the device. This is wrong, regardless if its request queue is
pm-aware or not.

When a non-passthrough command is terminated with CHECK CONDITION, request
sense is executed by hijacking the command descriptor. Since
scsi_eh_prep_cmnd() and scsi_eh_restore_cmnd() do not save/restore the
original command resid, the value returned on failure of the original
command is lost and replaced with the value set by the execution of the
request sense command. This value may in many instances be unaligned to the
device sector size, causing sd_done() to print a warning message about the
incorrect unaligned resid before the command is retried.
Fix this problem by saving the original command residual in struct
scsi_eh_save using scsi_eh_prep_cmnd() and restoring it in
scsi_eh_restore_cmnd(). In addition, to make sure that the request sense
command is executed with a correctly initialized command structure, also
reset the residual to 0 in scsi_eh_prep_cmnd() after saving the original
command value in struct scsi_eh_save.

Commit 88263208dd ("scsi: qla2xxx: Complain if sp->done() is not called
from the completion path") introduced the WARN_ON_ONCE in
qla2x00_status_cont_entry(). The assumption was that there is only one
status continuations element. According to the firmware documentation it is
possible that multiple status continuations are emitted by the firmware.

I've got a report about a UAS drive enclosure reporting back Sense: Logical
unit access not authorized if the drive it holds is password protected.
While the drive is obviously unusable in that state as a mass storage
device, it still exists as a sd device and when the system is asked to
perform a suspend of the drive, it will be sent a SYNCHRONIZE CACHE. If
that fails due to password protection, the error must be ignored.

Merge tag 'for-5.4/post-2019-09-24' of git://git.kernel.dk/linux-block
Pull more block updates from Jens Axboe:
"Some later additions that weren't quite done for the first pull
request, and also a few fixes that have arrived since.
This contains:
- Kill silly pktcdvd warning on attempting to register a non-scsi
passthrough device (me)
- Use symbolic constants for the block t10 protection types, and
switch to handling it in core rather than in the drivers (Max)
- libahci platform missing node put fix (Nishka)
- Small series of fixes for BFQ (Paolo)
- Fix possible nbd crash (Xiubo)"
* tag 'for-5.4/post-2019-09-24' of git://git.kernel.dk/linux-block:
block: drop device references in bsg_queue_rq()
block: t10-pi: fix -Wswitch warning
pktcdvd: remove warning on attempting to register non-passthrough dev
ata: libahci_platform: Add of_node_put() before loop exit
nbd: fix possible page fault for nbd disk
nbd: rename the runtime flags as NBD_RT_ prefixed
block, bfq: push up injection only after setting service time
block, bfq: increase update frequency of inject limit
block, bfq: reduce upper bound for inject limit to max_rq_in_driver+1
block, bfq: update inject limit only after injection occurred
block: centralize PI remapping logic to the block layer
block: use symbolic constants for t10_pi type
For N2N, the NPort ID is assigned by driver in the PLOGI ELS. According to
FW Spec the byte order for SID is not the same as DID.

During link up/bounce, qla driver would do command flush as part of
cleanup. In this case, the flush can intefere with FW state. This patch
allows FW to be in control of link up.
