3cbfbbf62f iscsi: do not caculate the CRC in multiple times
Since a PDU can be sentout in many times, so this
function is called multiple times, so move the
caculation function in spdk_iscsi_conn_write_pdu

855633a597 iscsi: Get LUN ID from task instead of Data-Out PDU to fix SCSI compliance test failure
A major SCSI compliance test expects that the LUN field is reserved
(not to be checked) in the SCSI Data-Out PDU.

In that test, the LUN field in the first SCSI Command PDU is 0 and
the LUN field in the SCSI Data-Out PDU sent in response to the R2T
is 0xFFFFFFFFFFFFFFFF. The TTT field in the SCSI Data-Out PDU is 0xF that
is copied from the R2T. 0xF is valid as TTT.

Hence spdk_iscsi_op_data() returns Check Condition because LUN is
not found.

This patch changes to get LUN ID from not the LUN field in the SCSI
Data-Out PDU but the saved task.

The following is excerpts from iSCSI specification (RFC7143). The
behavior of the SCSI compliance test looks against the specification
but changing SPDK will be safer.

11.7.4.  Target Transfer Tag and LUN

   On outgoing data, the Target Transfer Tag is provided to the target
   if the transfer is honoring an R2T.  In this case, the Target
   Transfer Tag field is a replica of the Target Transfer Tag provided
   with the R2T.

   On incoming data, the Target Transfer Tag and LUN MUST be provided by
   the target if the A bit is set to 1; otherwise, they are reserved.
   The Target Transfer Tag and LUN are copied by the initiator into the
   SNACK of type DataACK that it issues as a result of receiving a SCSI
   Data-In PDU with the A bit set to 1.

   The Target Transfer Tag values are not specified by this protocol,
   except that the value 0xffffffff is reserved and means that the
   Target Transfer Tag is not supplied.  If the Target Transfer Tag is
   provided, then the LUN field MUST hold a valid value and be
   consistent with whatever was specified with the command; otherwise,
   the LUN field is reserved.

b6ab3116fc iscsi: Load CHAP secrets from file once at boot and use them in memory
For secure iSCSI targets, dynamic reconfiguration of CHAP secrets is
must to have.

Currently CHAP secrets are loaded for every CHAP authentication
operation. The current implementation will not work correctly
when CHAP secrets in the file are changed dynamically.

If SPDK loads CHAP secrets from the file only at boot and they can be
configured by RPCs, user can change CHAP secrets safely during run time.

Even if there are any users who expect dynamic reconfiguration of
CHAP secrets based on the current implementation, if we provide
this better alternative based on RPCs, they will be able to continue to
satisfy their requirement.

This patch change the current implementation so that SPDK loads
CHAP secrets from the file once at boot and uses them in memory
hereafter.

Besides, use fixed size buffers to hold CHAP secrets.
Previously dynamically allocated buffers by strdup() had been used,
but it required many nomem checks and should be avoided.
Other iSCSI targets/initiators have used fixed size buffers and SPDK
follows others.

Set the size of buffers for both user names and secrets to 256 (the
last byte is for NULL termination). 256 is sufficiently large
compared with others.

CHANGELOG will be updated in the separate patch because new RPCs will
be added instead.

d393983d74 lib/iscsi: export FirstBurstLength as user configurable parameter
According to https://tools.ietf.org/html/rfc3720, the
default value for the FirstBurstLength is 65536 bytes
while SPDK iSCSI target picks the smaller 8192 as the
default setting. This value is the communication for
the iSCSI initiator to send the unsolicited data and
instead of having a fixed setting here, expose it as a
user configurable parameter to fit the real use case,
especially for the data out iSCSI write.

Example of usage as following in the iSCSI.conf:

FirstBurstLength 8192

This patch changes variable names for CHAP in discovery session

and discovery_auth_group to disable_chap, require_chap, mutual_chap,
and chap_group, respectively.

By this patch, the term "discovery" is removed but this will not
cause any confusion because the code of the use case of them is
clear and an new RPC set_iscsi_discovery_auth will be added in the
subsequent patches.

c8fd001075 iscsi: fix the primary iscsi task free in queued_datain_tasks
Reason: If the task is queued in scsi layer to handle, we
should free the task after calling the spdk_iscsi_task_cpl.
Otherwise, if only this task is executed (without subread tasks),
the task will be freed by the loop early, which will cause
the segment fault in spdk_iscsi_task_cpl function.

cefab5d647 iscsi: Support hot removal of LUN based on LUN open/close
When hot removal of a LUN is started, callback is called for each
iSCSI connection which accesses the LUN. Callback checks all transfer
tasks complete and then close the LUN.

If the connection clears all transfer tasks before getting all responses
to them from the initiator, the initiator continues to retry data write.
Hence the connection have to wait until all transfer tasks complete.

a02ab95ebb iscsi: Bug fix for residual count when length of data transfer from SCSI was 0
This bug was caused by the following two changes:

iscsi: Remove duplication of the variable for write completion to bdev
https://review.gerrithub.io/#/c/393582/

iscsi: restore data_transferred accumulation for read
https://review.gerrithub.io/#/c/393713/

For write, bytes_completed is always equal to data_transferred. However,
for read, bytes_completed is based on expected data transfer length and
data_transferred is actual read size. Hence bytes_completed cannot be
used to calculate residual counts.

One of the reason why this bug cannot be found was that there was not any
test case when task->scsi.data_transferred is 0 and task->scsi.length is
not 0. Hence UT code is also added.

Same bug will occur for read sense data. Hence UT code for read sense data
is added in the next patch.

60f1d52605 iscsi: restore data_transferred accumulation for read
In the patch 393582, by analyzing the code,
accumulation of write completion to bdev was duplicated by
data_transferred and bytes_completed.

Hence accumulation of data_transferred for write was intended
to be removed.

However by mistake accumulation of data_transferred for read
was removed.

In this patch restore accumulation of data_transferred for
read and remove accumlation of data_transferred for write.

Test code to catch this degradation will be added by another
patch soon.

8bb603da82 iscsi: Remove duplication of the variable for write completion to bdev
This patch will follow the change 393212 by Daniel.

For read command:
- primary's scsi.bytes_completed is for read completion from bdev.
- primary's scsi.data_transferred si for send completion to initiator.

Two variables have its own meaning, respectively.

However for write command:
- both primary's scsi.bytes_completed and scsi.data_transferred are
  for write completion to bdev.

Hence for write we should use only either one and it looks that
bytes_completed will be appropriate.

However current implementation handles a minor PDU error as Drop
