5af42000c1 lib/iscsi: Make max outstanding R2Ts per connection configurable
By the recent refactoring, we have no static size array for outstanding
R2Ts per connection. It looks that we do not have any critical reason
to prohibit us from making max outstanding R2Ts per connection configurable.

There are some use cases to use large write I/O intensively (e.g. 128KB).
Let such use cases change the value of max R2Ts per connection by their
responsibility to do performance tuning.

Maximum outstanding R2Ts per task are defined both for iSCSI target
and NVMe-TCP target but maximum outstanding R2Ts per connection is
unique for iSCSI target.

The next patch will add the corresponding iSCSI option.

fb229e1eb2 lib/iscsi: Count R2T and Data Out PDUs into PDU pool size
It is likely that the raw number 8 in the macro NUM_PDU_PER_CONNECTION
means 2 * DEFAULT_MAXR2T and the raw number 2 means R2T and Data Out, but
is not certain.

On the other hand, the next patch will make the max number of outstanding
R2Ts per connection configurable.

As a preparation to the next patch, add 2 * DEFAULT_MAXR2T explicitly
to the macro NUM_PDU_PER_CONNECTION.

The next patch will replace DEFAULT_MAXR2T by an new variable.

5b2c76f062 lib/iscsi: Make the max number of read subtasks for large read I/O configurable
For some use case that there is heavy large read I/O, the performance
bottleneck due to MAX_LARGE_DATAIN_PER_CONNECTION was reported.

The following assumes that all I/Os are large read.

Large read primary task whose I/O size is more than
SPDK_BDEV_LARGE_BUF_MAX_SIZE (=64KB) is split into multiple
read subtasks.

spdk_iscsi_globals::MaxQueueDepth limits maximum number of outstanding
read primary tasks, and MAX_LARGE_DATAIN_PER_CONNECTION (=64)
limits maximum number of outstanding read subtasks.

MAX_LARGE_DATAIN_PER_CONNECTION is also used to calculate PDU pool.

To remove the performance bottleneck, change the macro constant
MAX_LARGE_DATAIN_PER_CONNECTION to a global variable
spdk_iscsi_globals::MaxLargeDataInPerConnection.

We don't see any negative side effect if we set
spdk_iscsi_globals::MaxLargeDataInPerConnection to 64.

The use case that reported the performance issue will change the
value of spdk_iscsi_globals::MaxLargeDataInPerConnection by its own
responsibility.

The next patch will add the value of
spdk_iscsi_globals::MaxLargeDataInPerConnection to iSCSI options,
and make it configurable by JSON RPC.

e97fd6c936 lib/iscsi: Add iscsi_target_node_request_logout RPC
For the login redirection feature, the current implementation works
only if a portal is redirected from an initial portal to a redirect
portal. However, the login redirection feature should work even if a
portal is redirected from one redirect portal to another redirect
portal.

A public portal group knows only a redirect portal and does not know
the portal group of the redirect portal.

Moreover, it is very likely that an initial portal and a redirect portal
exist in different SPDK iSCSI target applications.

To cover all these concerns, add an new iscsi_target_node_request_logout
RPC to request connections whose portal group tag match for the target
node.

To cover potential use cases, make the second parameter portal group
tag optional.

8cf5581fa9 lib/iscsi: Remove async logout request from iscsi_target_node_redirect()
As written in doc/iscsi.md, typically the login redirection feature
will be used in scale out iSCSI target system, which runs multiple
SPDK iSCSI target applications.

In scale out iSCSI target system, the initial portal, the current
redirect portal, and the next redirect portal are likely to be in
different SPDK iSCSI target applications.

In this case, asynchronous logout request should be sent independently
from the iSCSI target application which has the current redirect portal.

However, we had added asynchronous logout request into the iSCSI target
application which has the next redirect portal. This idea works only
for the case that login is redirected from the initial portal to a
redirect portal.

We remove asynchronous logout request from iscsi_target_node_redirect()
in this patch, and update the corresponding help documents.

The next patch will add an new RPC to send asynchronous logout
request to all connections to the specified portal group and the
specified target.

If the portal group map of the target has a redirect portal,
iscsi_tgt_node_is_moved() fills the buffer by the redirected address
and returns true.

iscsi_op_login_check_target() calls iscsi_tgt_node_is_redirected() before
calling iscsi_tgt_node_access() because login redirection can be
checked before any or after all security check.

If iscsi_tgt_node_is_redirected() returns true, notify login redirection
to the corresponding initiator.

2c8309e00e lib/iscsi: Update redirect portal of public portal group
iscsi_tgt_node_redirect() updates redirect portal of the initial
portal iin a primary portal group for the target node.

Check if the specified portal group is a public portal group and is
mapped to the target node first.

Then if the passed IP address-port pair is NULL, clear the current
redirect setting. Public portal group and private portal group are
clearly separated and redirect portal must be chosen from a private
portal group. Hence this clear method is intuitive and simple.

If the passed IP address-port pair is not NULL, check if they are
valid, and are not in the specified portal group. Then update a
redirect portal of the portal group map.

Finally, send asynchronous logout request to all corresponding
initiators.

Besides, change allocating pg_map from malloc to calloc to initialize
redirect portal.

10d6218444 lib/iscsi: Create portal group as public or private portal group
In SPDK iSCSI target, portal group works almost as identifier of
portal.

To support iSCSI login redirection, we need to have two types of
portal groups, public and private portal groups.

We need portals of public portal groups to redirect to a portal in
a private portal groups at login via temporary login redirection
funciton, and we need to make SendTargets return only portals in
public portal groups.

To do these simply, we mark primary or secondary portal group expicitly
at its creation by this patch.

We have no particular requirement to keep both conn->outstanding_r2t_tasks

To improve readability and maintaineability, unify two into the latter,
conn->outstanding_r2t_tasks list. Update unit test accordingly.

d5f3f48b60 lib/iscsi: Fix iscsi_del_transfer_task deletes from both array and tailq
Previously iscsi_del_transfer_task() dequeued the task only from
the array conn->outstanding_r2t_tasks[].

process_non_read_task_completion() had dequeued the task from
the tailq conn->active_r2t_tasks then.

However abort_transfer_task_in_task_mgmt_resp had not dequeued the
task from the tailq conn->active_r2t_tasks then.

This was an apparent bug, and is fixed here. Update unit tests
accordingly.

41f59559e1 lib/iscsi: Return if conn->state is already exited when adding conn to poll group
Previously, we fixed a similar bug that iSCSI target got seg. fault
if connection is being exited between spdk_iscsi_conn_write_pdu()
and its callback iscsi_conn_login_pdu_success_complete() are executed.

This fix was not sufficient and we still saw similar error.

Not only socket write but also SPDK message is asynchronous and
connection may start exiting between iscsi_conn_schedule() and
iscsi_conn_full_feature_migrate().

This patch fix this new issue.

89ae0e3c62 lib/iscsi: Manage free connections not by array but by TAILQ
Previously free connections had been managed by g_conns_array,
and allocate_conn() gets the lowest free connection. This had worked
almost as LIFO, and the just freed connection had been reused
immediately to the new connection.

Using TAILQ makes management of free connections FIFO, and this will
be more intuitive and simpler, and avoid potential issues due to the
fact that we do not know the state INVALID is the current connection
or the current connection is exited and the new connection is allocated.

This patch includes following updates.

Remove the test condition that the connection ID should be zero.
Connection ID is used as Target Transfer Tag (TTT) and TTT is opaque
number. Hence requiring connection ID to be zero is not meaningful.

iscsi_conn_free() calls free_conn() while holding g_conns_mutex, but
iscsi_conn_construct() does not call free_conn() without holding
g_conns_mutex. Hence add g_conns_mutex to the latter.

d421876f98 lib/iscsi: Fix conn->state not go back to EXITING by using spdk_thread_send_msg
Updating conn->state had not been guarded by any mutex. When SPDK
iSCSI target has multiple SPDK threads, iscsi_drop_conns() may update
conn->state by a thread different from the thread of conn->pg.

This patch ensures conn->state is updated by the thread of conn->pg
by sending a message to the thread.

This fix is not perfect but connection reschedule is done only once
per connection when moving to the full feature phase. So this fix
will be simple and enough for now.

The following patch will remove the "spdk_" prefix from iSCSI
internal APIs. The iSCSI global data g_spdk_iscsi is also local in
SPDK iSCSI library. Hence rename it by g_iscsi for consistency.

de5f1ea0ba lib/iscsi: Create and terminate poll group threads explicitly
Login acceptor still runs on one of the default reactor threads,
but we move iSCSI poll group from the default reactor threads to
dedicated threads created at startup.

At startup, use reference count to detect completion and
move to the next step. By returning completion message to the init
thread, we can avoid using any atomic operation.

At shutdown, we can use spdk_for_each_channel() conveniently. Put
voluntary spdk_thread_exit() calls into the callback to
spdk_put_io_channel().

Moving login acceptor to a dedicated thread is another task.

To maintain the original behavior, number of threads created is
the number of cores that SPDK app uses.

to listen/connect, e.g., posix, or uring. With this patch, we can
designate the specified sock implementation if impl_name is not NULL
and valid. Otherwise, spdk_sock_listen/connect will try to use the sock
implementations in the list by order if impl_name is NULL.

Without this patch, the app will always use the same type of sock implementation
if the order is fixed. For example, if we have posix and uring together,
the first one will always be uring.

83bcd693b0 lib/iscsi: Assert if PDU ref count goes negative
Error log had been collected if PDU ref count went negative. However,
error log is not easy to notice.  SPDK iSCSI target is more stable
than before and SPDK iSCSI task has such assert.  Hence replace
error log by assert for PDU.

3c7890d24f lib/iscsi: Move iscsi_conn_handle_queued_datain_tasks() from iscsi.c to conn.c
Operations to queue iSCSI tasks are in iscsi.c and conn.c and cross
references due to this separation makes us difficult to create unit
tests.

This and subsequent patches will try to disentangle cross references
by moving some functions from iscsi.c to conn.c.

This patch moves spdk_iscsi_conn_handle_queued_datain_tasks() from
iscsi.c to conn.c.  For unit tests, we don't add anything new in
this patch and just create necessary simple stubs.  After code
movement, new unit tests will be added.

19eb63fcad lib/iscsi: Stop splitting immediately when aborting SCSI read I/O
We changed read I/O submission to stop splitting when detecting LUN
hotplug very recently. We can do the same refinement for read I/O
abortion.

In _iscsi_conn_abort_queued_datain_task(), set all remaining length
to the new task and complete it immediately. We keep the code to
process the case that queued_datain_task completed but is still in
queue, but we can change its if condition to assert.

Simplify the corresponding unit tests accordingly, and set
task->scsi.transfer_len in abort_queued_datain_tasks_test() to
exercise the changed paths.

In iscsi_pdu_payload_po_scsi_read(), if task->scsi.transfer_len is not
larger than SPDK_BDEV_LARGE_BUF_MAX_SIZE, no minimum calculation is
necessary and we can substitute task->scsi.transfer_len to
task->scsi.length simply.  This change is too small to be an independent
patch and is done together.
