commit 2f4a784f40f8d337d6590e2e93f46429052e15ac upstream.
Move ufshcd_set_variant call in ufs_hisi_init_common to common error
section at end of the function, and then jump to this from the error
checking statements for both devm_reset_control_get and
ufs_hisi_get_resource. This fixes the original commit (63a06181d7ce)
which was reverted due to the University of Minnesota problems.

commit 4d427b408c4c2ff1676966c72119a3a559f8e39b upstream.
This reverts commit 63a06181d7ce169d09843645c50fea1901bc9f0a.
Because of recent interactions with developers from @umn.edu, all
commits from them have been recently re-reviewed to ensure if they were
correct or not.
Upon review, this commit was found to be incorrect for the reasons
below, so it must be reverted. It will be fixed up "correctly" in a
later kernel change.
The original commit is incorrect, it does not properly clean up on the
error path, so I'll keep the revert and fix it up properly with a
follow-on patch.

[ Upstream commit 15cfef8623a449d40d16541687afd58e78033be3 ]
This fixes an issue hitting the BUG_ON() in ibmvfc_do_work(). When going
through a host action of IBMVFC_HOST_ACTION_RESET, we change the action to
IBMVFC_HOST_ACTION_TGT_DEL, then drop the host lock, and reset the CRQ,
which changes the host state to IBMVFC_NO_CRQ. If, prior to setting the
host state to IBMVFC_NO_CRQ, ibmvfc_init_host() is called, it can then end
up changing the host action to IBMVFC_HOST_ACTION_INIT. If we then change
the host state to IBMVFC_NO_CRQ, we will then hit the BUG_ON().
Make a couple of changes to avoid this. Leave the host action to be
IBMVFC_HOST_ACTION_RESET or IBMVFC_HOST_ACTION_REENABLE until after we drop
the host lock and reset or reenable the CRQ. Also harden the host state
machine to ensure we cannot leave the reset / reenable state until we've
finished processing the reset or reenable.

[ Upstream commit fffd18ec6579c2d9c72b212169259062fe747888 ]
Fix a crash caused by a double put on the node when the driver completed an
ACC for an unsolicted abort on the same node. The second put was executed
by lpfc_nlp_not_used() and is wrong because the completion routine executes
the nlp_put when the iocbq was released. Additionally, the driver is
issuing a LOGO then immediately calls lpfc_nlp_set_state to put the node
into NPR. This call does nothing.
Remove the lpfc_nlp_not_used call and additional set_state in the
completion routine. Remove the lpfc_nlp_set_state post issue_logo. Isn't
necessary.

commit 176ddd89171ddcf661862d90c5d257877f7326d6 upstream.
When the cache_type for the SCSI device is changed, the SCSI layer issues a
MODE_SELECT command. The caching mode details are communicated via a
request buffer associated with the SCSI command with data direction set as
DMA_TO_DEVICE (scsi_mode_select()). When this command reaches the libata
layer, as a part of generic initial setup, libata layer sets up the
scatterlist for the command using the SCSI command (ata_scsi_qc_new()).
This command is then translated by the libata layer into
ATA_CMD_SET_FEATURES (ata_scsi_mode_select_xlat()). The libata layer treats
this as a non-data command (ata_mselect_caching()), since it only needs an
ATA taskfile to pass the caching on/off information to the device. It does
not need the scatterlist that has been setup, so it does not perform
dma_map_sg() on the scatterlist (ata_qc_issue()). Unfortunately, when this
command reaches the libsas layer (sas_ata_qc_issue()), libsas layer sees it
as a non-data command with a scatterlist. It cannot extract the correct DMA
length since the scatterlist has not been mapped with dma_map_sg() for a
DMA operation. When this partially constructed SAS task reaches pm80xx
LLDD, it results in the following warning:
"pm80xx_chip_sata_req 6058: The sg list address
start_addr=0x0000000000000000 data_len=0x0end_addr_high=0xffffffff
end_addr_low=0xffffffff has crossed 4G boundary"
Update libsas to handle ATA non-data commands separately so num_scatter and
total_xfer_len remain 0.

commit fef912bf860e8e7e48a2bfb978a356bba743a8b7 upstream.
Update device_add_disk() to take an 'groups' argument so that
individual drivers can register a device with additional sysfs
attributes.
This avoids race condition the driver would otherwise have if these
groups were to be created with sysfs_add_groups().

commit f9dbdf97a5bd92b1a49cee3d591b55b11fd7a6d5 upstream.
Open-iSCSI sends passthrough PDUs over netlink, but the kernel should be
verifying that the provided PDU header and data lengths fall within the
netlink message to prevent accessing beyond that in memory.

As the iSCSI parameters are exported back through sysfs, it should be
enforcing that they never are more than PAGE_SIZE (which should be more
than enough) before accepting updates through netlink.
Change all iSCSI sysfs attributes to use sysfs_emit().

Protect the iSCSI transport handle, available in sysfs, by requiring
CAP_SYS_ADMIN to read it. Also protect the netlink socket by restricting
reception of messages to ones sent with CAP_SYS_ADMIN. This disables
normal users from being able to end arbitrary iSCSI sessions.

[ Upstream commit 764907293edc1af7ac857389af9dc858944f53dc ]
While testing live partition mobility, we have observed occasional crashes
of the Linux partition. What we've seen is that during the live migration,
for specific configurations with large amounts of memory, slow network
links, and workloads that are changing memory a lot, the partition can end
up being suspended for 30 seconds or longer. This resulted in the following
scenario:
CPU 0 CPU 1
------------------------------- ----------------------------------
scsi_queue_rq migration_store
-> blk_mq_start_request -> rtas_ibm_suspend_me
-> blk_add_timer -> on_each_cpu(rtas_percpu_suspend_me
_______________________________________V
|
V
-> IPI from CPU 1
-> rtas_percpu_suspend_me
-> __rtas_suspend_last_cpu
-- Linux partition suspended for > 30 seconds --
-> for_each_online_cpu(cpu)
plpar_hcall_norets(H_PROD
-> scsi_dispatch_cmd
-> scsi_times_out
-> scsi_abort_command
-> queue_delayed_work
-> ibmvfc_queuecommand_lck
-> ibmvfc_send_event
-> ibmvfc_send_crq
- returns H_CLOSED
<- returns SCSI_MLQUEUE_HOST_BUSY
-> __blk_mq_requeue_request
-> scmd_eh_abort_handler
-> scsi_try_to_abort_cmd
- returns SUCCESS
-> scsi_queue_insert
Normally, the SCMD_STATE_COMPLETE bit would protect against the command
completion and the timeout, but that doesn't work here, since we don't
check that at all in the SCSI_MLQUEUE_HOST_BUSY path.
In this case we end up calling scsi_queue_insert on a request that has
already been queued, or possibly even freed, and we crash.
The patch below simply increases the default I/O timeout to avoid this race
condition. This is also the timeout value that nearly all IBM SAN storage
recommends setting as the default value.

[ Upstream commit b112036535eda34460677ea883eaecc3a45a435d ]
Phil Oester reported that a fix for a possible buffer overrun that I sent
caused a regression that manifests in this output:
Event Message: A PCI parity error was detected on a component at bus 0 device 5 function 0.
Severity: Critical
Message ID: PCI1308
The original code tried to handle the sense data pointer differently when
using 32-bit 64-bit DMA addressing, which would lead to a 32-bit dma_addr_t
value of 0x11223344 to get stored
32-bit kernel: 44 33 22 11 ?? ?? ?? ??
64-bit LE kernel: 44 33 22 11 00 00 00 00
64-bit BE kernel: 00 00 00 00 44 33 22 11
or a 64-bit dma_addr_t value of 0x1122334455667788 to get stored as
32-bit kernel: 88 77 66 55 ?? ?? ?? ??
64-bit kernel: 88 77 66 55 44 33 22 11
In my patch, I tried to ensure that the same value is used on both 32-bit
and 64-bit kernels, and picked what seemed to be the most sensible
combination, storing 32-bit addresses in the first four bytes (as 32-bit
kernels already did), and 64-bit addresses in eight consecutive bytes (as
64-bit kernels already did), but evidently this was incorrect.
Always storing the dma_addr_t pointer as 64-bit little-endian,
i.e. initializing the second four bytes to zero in case of 32-bit
addressing, apparently solved the problem for Phil, and is consistent with
what all 64-bit little-endian machines did before.
I also checked in the history that in previous versions of the code, the
pointer was always in the first four bytes without padding, and that
previous attempts to fix 64-bit user space, big-endian architectures and
64-bit DMA were clearly flawed and seem to have introduced made this worse.

Users can initiate resets to specific SCSI device/target/host through
IOCTL. When this happens, the SCSI cmd passed to eh_device/target/host
_reset_handler() callbacks is initialized with a request whose tag is -1.
In this case it is not right for eh_device_reset_handler() callback to
count on the LUN get from hba->lrb[-1]. Fix it by getting LUN from the SCSI
device associated with the SCSI cmd.
