1f54682314 scsi: lpfc: NVMe remote port devloss_tmo from lldd
nvme-fc allows the driver to specify a default devloss_tmo value when
registering the remote port. The lpfc driver is currently not doing so,
although it is implementing a driver internal node loss value of 30s which
also is used on the SCSI FC remote port. As no devloss_tmo is set, the
nvme-fc transport defaults to 60s. So there are competing timers.

Additionally, due to the competing timers, it is possible the NVMe rport is
removed but the SCSI rport remains. It is possible that the SCSI FC rport,
which was registered for the NVMe port even if it doesn't utilize the SCSI
protocol, had been tuned to not match either the 60s (nvme-fc default) or
30s (lldd default), it gets out of whack. The lldd will defer to the SCSI
FC rport as long as the SCSI FC rport has not had its devloss_tmo expire.

Correct the situation by specifying a default devloss_tmo to the nvme-fc
transport when registering the rport.  Take the value from the SCSI FC
rport if it exists, otherwise use the driver default.

e721eb0616 scsi: scsi_transport_fc: Match HBA Attribute Length with HBAAPI V2.0 definitions
According to 'include/scsi/scsi_transport_fc.h':

 "Attributes are based on HBAAPI V2.0 definitions"

... so it seems sane to match the 'HBA Attribute Length' to them.

If we don't, the compiler complains that the copied data will be truncated.

30f67481a1 scsi: scsi_debug: Update documentation url and bump version
This driver maintains a version number which is cross-referenced in the
documentation (e.g. to indicate when features are added or changed) and
exposed through the responses to various SCSI commands. For example the
version number is use as the Product Revision number in standard SCSI
INQUIRY responses issued by this driver. The version date string is placed
in a vendor specific area in each standard SCSI INQUIRY response. This
patch bumps both.

Update the driver documentation URL that appears at the top of the driver
source file.

3a90a63d02 scsi: scsi_debug: every_nth triggered error injection
This patch simplifies, or at least makes more consistent, the way setting
the every_nth parameter injects errors. Here is a list of 'opts' flags and
in which cases they inject errors when abs(every_nth)%command_count == 0 is
reached:

  - OPT_RECOVERED_ERR: issued on READ(*)s, WRITE(*)s and
                       WRITE_SCATTEREDs
  - OPT_DIF_ERR:       issued on READ(*)s, WRITE(*)s and
                       WRITE_SCATTEREDs
  - OPT_DIX_ERR:       issued on READ(*)s, WRITE(*)s and
                       WRITE_SCATTEREDs
  - OPT_SHORT_TRANSFER: issued on READ(*)s
  - OPT_TRANSPORT_ERR: issued on all commands
  - OPT_CMD_ABORT:     issued on all commands

The other uses of every_nth were not modified.

Previously if, for example, OPT_SHORT_TRANSFER was armed then if
(abs(every_nth) % command_count == 0) occurred during a command that was
_not_ a READ, then no error injection occurred. This behaviour puzzled
several testers. Now a global "inject_pending" flag is set and the _next_
READ will get hit and that flag is cleared. OPT_RECOVERED_ERR, OPT_DIF_ERR
and OPT_DIX_ERR have similar behaviour. A downside of this is that there
might be a hang-over pending injection that gets triggered by a following
test.

Also expand the every_nth runtime parameter so that it can take hex value
(i.e. with a leading '0x') as well as a decimal value. Now both the 'opts'
and the 'every_nth' runtime parameters can take hexadecimal values.

c10fa55f5e scsi: scsi_debug: Support hostwide tags
Many SCSI HBAs support a hostwide tagset, whereby each command submitted to
the HW from all submission queues must have a unique tag identifier.

Normally this unique tag will be in the range [0, max queue], where "max
queue" is the depth of each of the submission queues.

Add support for this hostwide tag feature, via module parameter
"host_max_queue". A non-zero value means that the feature is enabled. In
this case, the submission queues are not exposed to upper layer, i.e. from
blk-mq prespective, the device has a single hw queue. There are 2 reasons
for this:

 a. It is assumed that the host can support nr_hw_queues * can_queue
    commands, but this is not true for hostwide tags

 b. For nr_hw_queues != 0, the request tag is not unique over all HW
    queues, and some HBA drivers want to use this tag for the hostwide tag

However, like many SCSI HBA drivers today - megaraid sas being an example -
the full set of HW submission queues are still used in the LLDD driver. So
instead of using a complicated "reply_map" to create a per-CPU submission
queue mapping like megaraid_sas (as it depends on a PCI device + MSIs) -
use a simple algorithm:

    hwq = cpu % queue count

If the host_max_queue param is set non-zero, then the max queue depth is
fixed at this value also.

If and when hostwide shared tags are supported in blk-mq/scsi mid-layer,
then the policy to set nr_hw_queues = 0 for hostwide tags can be revised.

Add inline encryption support to ufs-mediatek.

The standards-compliant parts, such as querying the crypto capabilities and
enabling crypto for individual UFS requests, are already handled by
ufshcd-crypto.c, which itself is wired into the blk-crypto framework.

However MediaTek UFS host requires a vendor-specific hce_enable operation
to allow crypto-related registers being accessed normally in kernel.  After
this step, MediaTek UFS host can work as standard-compliant host for
inline-encryption related functions.
