4b29cb6197 scsi: ibmvfc: Avoid link down on FS9100 canister reboot
When a canister on a FS9100, or similar storage, running in NPIV mode, is
rebooted, its WWPNs will fail over to another canister. When this occurs,
we see a WWPN going away from the fabric at one N-Port ID, and, a short
time later, the same WWPN appears at a different N-Port ID.  When the
canister is fully operational again, the WWPNs fail back to the original
canister. If there is any I/O outstanding to the target when this occurs,
it will result in the implicit logout the ibmvfc driver issues before
removing the rport to fail. When the WWPN then shows up at a different
N-Port ID, and we issue a PLOGI to it, the VIOS will see that it still has
a login for this WWPN at the old N-Port ID, which results in the VIOS
simulating a link down / link up sequence to the client, in order to get
the VIOS and client LPAR in sync.

The patch below improves the way we handle this scenario so as to avoid the
link bounce, which affects all targets under the virtual host adapter. The
change is to utilize the Move Login MAD, which will work even when I/O is
outstanding to the target. The change only alters the target state machine
for the case where the implicit logout fails prior to deleting the rport.
If this implicit logout fails, we defer deleting the ibmvfc_target object
after calling fc_remote_port_delete. This enables us to later retry the
implicit logout after terminate_rport_io occurs, or to issue the Move Login
request if a WWPN shows up at a new N-Port ID prior to this occurring.

This has been tested by IBM's storage interoperability team on a FS9100,
forcing the failover to occur. With debug tracing enabled in the ibmvfc
driver, we confirmed the move login was sent in this scenario and confirmed
the link bounce no longer occurred.

782e2efb74 scsi: ufs: Fix NOP OUT timeout value
Boot occasionally fails with some Samsung low-power UFS devices. The reason
is that these devices have a little bit higher latency for NOP OUT
responses. This causes boot to fail because the NOP OUT command is issued
during initialization to check whether the device transport protocol is
ready or not. Increase NOP_OUT_TIMEOUT value from 30 to 50ms.

6c5dee1875 scsi: sd: sd_zbc: Fix ZBC disk initialization
Make sure to call sd_zbc_init_disk() when the sdkp->zoned field is known,
that is, once sd_read_block_characteristics() is executed in
sd_revalidate_disk(), so that host-aware disks also get initialized.  To do
so, move sd_zbc_init_disk() call in sd_zbc_revalidate_zones() and make sure
to execute it for all zoned disks, including for host-aware disks used as
regular disks as these disk zoned model may be changed back to BLK_ZONED_HA
when partitions are deleted.

27ba3e8ff3 scsi: sd: sd_zbc: Fix handling of host-aware ZBC disks
When CONFIG_BLK_DEV_ZONED is disabled, allow using host-aware ZBC disks as
regular disks. In this case, ensure that command completion is correctly
executed by changing sd_zbc_complete() to return good_bytes instead of 0
and causing a hang during device probe (endless retries).

When CONFIG_BLK_DEV_ZONED is enabled and a host-aware disk is detected to
have partitions, it will be used as a regular disk. In this case, make sure
to not do anything in sd_zbc_revalidate_zones() as that triggers warnings.

Since all these different cases result in subtle settings of the disk queue
zoned model, introduce the block layer helper function
blk_queue_set_zoned() to generically implement setting up the effective
zoned model according to the disk type, the presence of partitions on the
disk and CONFIG_BLK_DEV_ZONED configuration.

7f04839ec4 scsi: lpfc: Fix initial FLOGI failure due to BBSCN not supported
Initial FLOGIs are failing with the following message:

 lpfc 0000:13:00.1: 1:(0):0820 FLOGI Failed (x300). BBCredit Not Supported

In a prior patch, the READ_SPARAM command was re-ordered to post after
CONFIG_LINK as the driver is expected to update the driver's copy of the
service parameters for the FLOGI payload. If the bb-credit recovery feature
is enabled, this is fine. But on adapters were bb-credit recovery isn't
enabled, it would cause the FLOGI to fail.

Fix by restoring the original command order (READ_SPARAM before
CONFIG_LINK), and after issuing CONFIG_LINK, detect bb-credit recovery
support and reissuing READ_SPARAM to obtain the updated service parameters
(effectively adding in the fix command order).

31a3271ff1 scsi: qla2xxx: Handle incorrect entry_type entries
It was observed on an ISP8324 16Gb HBA with fw=8.08.203 (d0d5) in a
PowerPC64 machine that pkt->entry_type was MBX_IOCB_TYPE/0x39 with an
sp->type SRB_SCSI_CMD which is invalid and should not be possible.

Reading the entry_type from the crash dump shows the expected value of
STATUS_TYPE/0x03 but the call trace shows that qla24xx_mbx_iocb_entry() is
used.

Add a check to verify for consistency and reset the HBA if an invalid state
is reached. Obviously, this is only a workaround until the real problem is
solved.

c0014f9421 scsi: qla2xxx: Warn if done() or free() are called on an already freed srb
Emit a warning when ->done or ->free are called on an already freed
srb. There is a hidden use-after-free bug in the driver which corrupts
the srb memory pool which originates from the cleanup callbacks.

An extensive search didn't bring any lights on the real problem. The
initial fix was to set both pointers to NULL and try to catch invalid
accesses. But instead the memory corruption was gone and the driver
didn't crash. Since not all calling places check for NULL pointer, add
explicitly default handlers. With this we workaround the memory
corruption and add a debug help.

In sas_notify_lldd_dev_found(), if we can't allocate the necessary
resources, then it seems like the wrong thing to mark the device as found
and to increment the reference count.  None of the callers ever drop the
reference in that situation.
