This patch provides an interface to do the following (using MBC 0x3B):
- Displays (in hex) the LED config words for all three LEDs.
- Programs the config words for one LED or for all three LEDs.
The sysfs node defined is named beacon_config.
First, to allow driver to gain LED control, do this:
# echo 1 > /sys/class/scsi_host/host#/beacon
Then, to display config words for all three LEDs do this:
# cat /sys/class/scsi_host/host#/beacon_config
To set config words for all three LEDs do this:
# echo 3 xxxx yyyy zzzz > /sys/class/scsi_host/host#/beacon_config
Or, to set config word for a specific single LED n do this:
# echo n xxxx > /sys/class/scsi_host/host#/beacon_config
where n is the LED number (0, 1, 2)
Finally, to restore LED control back to firmware, do this:
# echo 0 > /sys/class/scsi_host/host#/beacon

On certain cases when response length is less than 32, NVME response data
is supplied inline in IOCB. This is indicated by some combination of state
flags. There was an instance when a high, and incorrect, response length
was indicated causing driver to overrun buffers. Fix this by checking and
limiting the response payload length.

This patch does not change the behavior when using one of the vdisk handlers.
When using dev_disk to forward SCSI commands from one SCST node to another,
this patch causes RTPG and STPG commands to be processed on the source SCST
node (as it should) instead of on the destination SCST node.

Add the 'forward_dst' sysfs attribute next to the 'forwarding' attribute. The

This patch suppresses the following Coverity complaint:
CID 119689 (#1 of 1): Out-of-bounds access (OVERRUN)
overrun-buffer-arg: Overrunning struct type scst_event of 64 bytes by
passing it to a function which accesses it at byte offset 3135 using
argument 64UL + payload_len (which evaluates to 3136). [Note: The source
code implementation of the function has been overridden by a builtin model.]

Designated initializers are required for GCC to safely implement
RANDSTRUCT, a GCC plugin pulled from the Grsecurity patch set
upstream ~2017.
Fix the compile error caused by implementation of sys_alloc_fns
by rewriting the struct with designated members.
