Initialise the t10_wwn vendor, model and revision defaults when a device is
allocated instead of when it's enabled. This ensures that custom vendor or
model strings set prior to enablement are not later overwritten with
default values.
The TRANSPORT_FLAG_PASSTHROUGH conditional can be dropped for the following
reasons:
- target_core_pscsi overwrites the defaults in the
pscsi_configure_device() callback.
+ the contents is then only used for ConfigFS via
$pscsi_dev/statistics/scsi_lu/vend, etc.
- target_core_user doesn't touch the defaults, nor are they used for
anything outside of ConfigFS.

In preparation for supporting user provided vendor strings, add an extra
byte to the vendor, model and revision arrays in struct t10_wwn. This
ensures that the full INQUIRY data can be carried in the arrays along with
a null-terminator.
Change a number of array readers and writers so that they account for
explicit null-termination:
- The pscsi_set_inquiry_info() and emulate_model_alias_store() codepaths
don't currently explicitly null-terminate; fix this.
- Existing t10_wwn field dumps use for-loops which step over
null-terminators for right-padding.
+ Use printf with width specifiers instead.

4.3.1 ASCII data field requirements
ASCII data fields shall contain only ASCII printable characters (i.e.,
code values 20h to 7Eh) and may be terminated with one or more ASCII null
(00h) characters. ASCII data fields described as being left-aligned
shall have any unused bytes at the end of the field (i.e., highest

(20h).
LIO currently space-pads the T10 VENDOR IDENTIFICATION and PRODUCT
IDENTIFICATION fields in the standard INQUIRY data. However, the PRODUCT
REVISION LEVEL field in the standard INQUIRY data as well as the T10 VENDOR
IDENTIFICATION field in the INQUIRY Device Identification VPD Page are
zero-terminated/zero-padded.
Fix this inconsistency by using space-padding for all of the above fields.

Introduce separate zfcp module parameters to individually select support

or DIX+DIF which can cause trouble (zfcp.dix, new, disabled).
If DIX is enabled, we warn on zfcp driver initialization. As before, this
also reduces the maximum I/O request size to half, to support the worst
case of merged single sector requests with one protection data scatter
gather element per sector. This can impact the maximum throughput.
In DIF-only mode (zfcp.dif=1 zfcp.dix=0), we can use the full maximum I/O

Due to the "make ABORT and LUN RESET handling synchronous" patch, cmd->work

the regular command execution code is sequential per command, no locking is

Instead of invoking target driver callback functions from the context that
handles an abort or LUN RESET task management function, only set the abort
flag from that context and perform the actual abort handling from the
context of the regular command processing flow. This approach has the
advantage that the task management code becomes much easier to read and to
verify since the number of potential race conditions against the command
processing flow is strongly reduced.
This patch has been tested by running the following two shell commands
concurrently for about ten minutes for both the iSCSI and the SRP target
drivers ($dev is an initiator device node connected with storage provided
by the target driver under test):
* fio with data verification enabled on a filesystem mounted on top of
$dev.
* while true; do sg_reset -d $dev; echo -n .; sleep .1; done

The TASK ABORTED STATUS (TAS) bit is defined as follows in SAM:
"TASK_ABORTED: this status shall be returned if a command is aborted by a
command or task management function on another I_T nexus and the control
mode page TAS bit is set to one". TAS handling is spread over the target
core and the iSCSI target driver. If a LUN RESET is received, the target
core will send the TASK_ABORTED response for all commands for which such a
response has to be sent. If an ABORT TASK is received, only the iSCSI
target driver will send the TASK_ABORTED response for the commands for
which that response has to be sent. That is a bug since all target drivers
have to honor the TAS bit. Fix this by moving the code that handles TAS
from the iSCSI target driver into the target core. Additionally, if a
command has been aborted, instead of sending the TASK_ABORTED status from
the context that processes the SCSI command send it from the context of the
ABORT TMF. The core_tmr_abort_task() change in this patch causes the
CMD_T_TAS flag to be set if a TASK_ABORTED status has to be sent back to
the initiator that submitted the command. If that flag has been set
transport_cmd_finish_abort() will send the TASK_ABORTED response.

A quote from SAM-5: "The order in which task management requests are
processed is not specified by the SCSI architecture model. The SCSI
architecture model does not require in-order delivery of such task
management requests or processing by the task manager in the order
received. To guarantee the processing order of task management requests
referencing sent to a specific logical unit, an application client should
not have more than one such task management request pending to that logical
unit." This means that it is safe to use the system workqueues instead of
tmr_wq for processing TMFs. An intended side effect of this patch is that
it enables concurrent processing of TMFs.
