8cc7b0bc4d lib/iscsi: Set destructed at the start of target node destruction
Add the flag destructed to struct spdk_iscsi_tgt_node and
iscsi_op_login_check_target() refers it and returns
ISCSI_LOGIN_TARGET_REMOVED if it is true.

When destructing iSCSI target node, it will be nice if iSCSI library
can stop further connections are created but, connections are not
associated with any target node until processing login. Hence stop
creating sessions instead.

Additionally, when destructing iSCSI target node, if the flag destructed
is already set, return immediately, and the flag destructed does not
affect discovery session.

5a1dc44423 iscsi: Fix LUN ID in Ready to Transfer PDUs
LUN ID is not converted from integer to structure and integer is
set to R2T PDUs.

Popular iSCSI initiators don't check this value and work correctly.

This patch uses the public helper function of the SCSI library
to fix the issue.

Additionally, private helper function to convert structure to
integer for LUN ID is replaced to the public helper function
of the SCSI library.

893e02a54f iscsi: Remove the prefix spdk_ from names of private functions
iSCSI library had used the prefix spdk_ for most functions regardless
of private or public. Using the prefix spdk_ only for public functions
will be helpful to distinguish private and public functions, and
will be helpful to investigate issues or do further improvement.

Besides in iscsi.c static variable spdk_arc4random_initialized had
the prefix spdk_, and change it to g_arc4random_initialized according
to the SPDK's good practice.

iSCSI library still have some issues but is more stable than before
and now will be the good time to adjust the naming rule to other
libraries.

This patch doesn't change any behavior.

fa7dd957ee iscsi: Reduce required free iovecs from 5 to 1 to flush PDUs
Upcoming patches will support DIF insert and strip feature in
iSCSI target and the feature will be implemented by utilizing
iovecs.

Even when we support the DIF feature, we want to keep current
batched PDU flush, and current requirement that there must be
enough free iovecs to map all segments of a PDU is too strict.

This patch alleviates the requirement by passing remaining
number of iovecs to spdk_iscsi_build_iovs().

879386d759 iscsi: Unify build and fast-forward iovecs to flush PDUs
Building iovecs had been done in spdk_iscsi_build_iovs() and
fast-forwarding iovecs for the partially written first PDU had
been done in-line separately.

This patch unifies these two operations into spdk_iscsi_build_iovs().

Fast-forwarding iovecs is necessary only for the first PDU, but the
operation is applied to all PDUs after this patch.

Extra overhead will be negligible because usually at most two
iovecs are consumed, one is for the base header segment and another
is for the data segment.

a207f575fb iscsi: Abort queued datain tasks before submitting abort task set to SCSI layer
This patch is for ABORT TASK SET and LUN RESET.

iSCSI layer doesn't have pending queue and hence if the target task
is read task and is queued in queued_datain_tasks, it must be
aborted before submitting ABORT TASK to SCSI layer.

Aborting the target task may not complete by an iteration because
submitted read tasks are limited. Hence use poller to complete abortion
by repetition.

5124f87f4e iscsi: Abort queued datain task before submitting abort to SCSI layer
By up to the previous patch in the patch series, unexpected behavior
due to write tasks in task management commands have been fixed.

But unexpected behavior due to read tasks in task management commands
have been still observed.

Remaining patches in the patch series will fix the unexpected behavior
due to read tasks in task management commands.

This patch is for ABORT TASK.

ABORT TASK is not supported in SCSI layer yet. But the initiator
doesn't care about the failure is due to not-supported or failure.
It must be avoided that the task management command returns SCSI Good
but some tasks are not aborted and return SCSI Good later. On the other
hand, it is acceptable that the task management command returns
failure but some tasks are partially aborted.

Hence this patch adds operation without checking the support status
in SCSI layer.

iSCSI layer doesn't have pending queue and hence if the target task
is read task and is queued in queued_datain_tasks, it must be
aborted before submitting ABORT TASK to SCSI layer.

Aborting the target task may not complete by an iteration because
submitted read tasks are limited. Hence use poller to complete abortion
by repetition.

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.

3e66e72651 ut/iscsi: Add unit test for residual count of SCSI Request Sense
Current SPDK implements SCSI Request Sense command so that a SCSI
Data-In PDU and a SCSI Response PDU are returned and underflow are
set to both of them.

On the other hand, some implementation return only a SCSI Data-In
PDU and some implementation return only a SCSI Response PDU.

Adding test code will be helpful for every implementation.

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.

56d35c5d13 test: forbid use of CU_ASSERT_FATAL
Static analyzers don't see CU_ASSERT_FATAL as truly fatal,
and will complain that code later in the function may try
to dereference a NULL pointer.  So we added SPDK_CU_ASSERT_FATAL
which should be used instead.

This still trips people up sometimes though - the static analyzer
complains and then the developer will add other checks that
pointers are not NULL.

So instead, forbid use of CU_ASSERT_FATAL through check_format.sh
and explain why.  While here, fix up all of the existing CU_ASSERT_FATAL
usages to either CU_ASSERT or SPDK_CU_ASSERT_FATAL.

f587197d21 iscsi&iscsi/ut: Unify cpumask decode between iSCSI.conf and JSON-RPC
Currently cpumask cannot be specified for each portal when it is
created by JSON-RPC and portal group creation is not unified
between iSCSI.conf and JSON-RPC.

This patch does the following:
 - cpumask string is decoded in spdk_iscsi_portal_create() which
   is common between iSCSI.conf and JSON-RPC.
 - parsing configline of portal is difficult to understand and
   hence it is refactored.
 - UT code is added.

 JSON-RPC will be added by the next patch.

respectively:
- spdk_iscsi_tgt_node_allow_ipv6()
- spdk_iscsi_tgt_node_allow_ipv4()
- spdk_iscsi_tgt_node_allow_netmask()
- spdk_iscsi_tgt_node_access()

Using bool for this purpose will avoid our misunderstanding.
