d999e6af7d iscsi: Move connection init right after iSCSI global params init
Pool of iSCSI connections and related variables are initialized in
initialize_iscsi_conns().

Currently initialize_iscsi_conns() is located after configuration of
target nodes by .INI config file.

Configuration of target nodes can be done by JSON-RPC but connection
initialization must be completed before starting JSON-RPC.

iSCSI connections don't belong to iSCSI global params directly and
hence move connection initialization right after initialization of
iSCSI global params.

The purpose of the patch series is
- to separate iSCSI subsystem initialization and iSCSI subsystem
  configuration, and
- to develop a new JSON-RPC by reusing the separated iSCSI subsystem
  initialization.

180af18cc7 iscsi: Move PDU, session, and task pool init into iSCSI global params init
iSCSI subsystem have a pool for PDU, session, and task, respectively.

They belong to the struct spdk_iscsi_globals and are initialized by
using the parameters of the struct spdk_iscsi_globals.

Hence their initialization should be located just behind the setup of
parameters of the struct spdk_iscsi_globals.

The purpose of the patch series is
- to separate iSCSI subsystem initialization and iSCSI subsystem
  configuration, and
- to develop a new JSON-RPC by reusing the separated iSCSI subsystem
  initialization.

ef02d13d3e iscsi: Move PG and IG configuration right before target nodes configuration

6ef949f276 iscsi: Extract TAILQ_INIT from IG, PG, and target nodes configuration
There are four configurable components, portal, portal group, target node,
and initiator group in iSCSI.

They have a TAILQ to manage their objects, respectively.
Currently each TAILQ initialization is done together with its object
creation by .INI config file.

This patch separates TAILQ initialization from object creation for four
configurable components in iSCSI.

The purpose of the patch series is
- to separate iSCSI subsystem initialization and iSCSI subsystem
  configuration, and
- to develop a new JSON-RPC by reusing the separated iSCSI subsystem
  initialization.

230833d8ce iscsi: Remove the variable ntargets from iscsi global params

Now iSCSI target node is managed by a linked list and ntargets

2ecab7bd6a net: remove ability to override default net_framework
In early days of SPDK, there was an experimental userspace
TCP stack called libuns.  The SPDK iSCSI target supported
using either the default POSIX/kernel TCP stack or this
libuns TCP stack.

libuns is no longer in use, but work has started on
supporting the FD.io VPP TCP userspace stack.  Abstractions
are being put in place to allow *both* the POSIX and VPP
stacks simultaneously.

So remove the concept of a "default" net_framework that is
defined with weak symbols that can be overridden by another
object file.  While here, also remove the "clear_socket_association"
concept which was specific to libuns.

2982a74df9 iscsi&rpc: Add new initiator information to an existing initiator group
Adding new initiator to an existing initiator group to allow login
will be usual. This patch support the following JSON-RPC commands:
- add_initiators_to_initiator_group
- delete_initiators_from_initiator_group

Both initiator's name and netmask are optional but already added
name or netmask cannot be added.

Test code is added too.

e3f2a3949d sock: add sock_group abstraction
For now, this provides common abstraction for Linux epoll
and FreeBSD kqueue.  It also provides the basis for future
changes where alternate userspace TCP stacks have their own
mechanism for polling a group of descriptors.

While here, remove old epoll/kqueue code in iscsi/conn.c that
was commented out when the iSCSI idle connection code was
recently removed - we now have a real implementation of it
in sock.c so the original code is no longer needed as a
reference.

This provides an abstraction layer around TCP

we don't want to be tied to integers for alternative

2ea005f0a9 iscsi: Unify the ordering of PG create_op between conf-file and JSON-RPC
Orderings of portal group create operation are diferrent between
config file and JSON-RPC. Unification is necessary for correct
concurrency control and the global accept poller like NVMf-tgt.
Hence unify the ordering of operations in this patch.

Common ordering of portal group create operation between configuration
file  and JSON-RPC after this patch is the following:
 - create a portal group
 - create portals
 - add the portals to the portal group
 - open the portals of the portal group
 - add the portal group to the global portal group list

After this patch, the gap between listening socket and accepting socket
will be increased a little when portals groups are creted by config file.
However this will cause no issue because of the TCP backlog and resend
mechanism.

Besides, necessary concurrency control is added and minor refactoring
is done.

About portal group delete operation, orderings of application shutdown
and JSON-RPC are already unified.

601bcbcf66 util: extend cpumask to hold more than 64 cpus
Fixes github issue #218.

This patch introduces spdk_cpuset object to store and manipulate
the set of individual CPUs. The main objective of this object is
to replace cpumask declared as uint64_t and extend the limitation
of supported CPUs (lcores) above 64 CPUs.

spdk_cpuset is always allocated dynamically and accessed by opaque
pointer, what makes it easier to extend in the future without
breaking API/ABI.

This patch also extends parsing function allowing to set cpumask
using a list of cpus e.g. "[0-4,10,12]" sets mask of 0,1,2,3,4,10,12
as well as hexadecimal string with and without "0x" prefix.

7bae25dfcd iscsi: remove flush timeout
This concept was added very early in the SPDK iSCSI target
development process when there was a high focus on maximizing
throughput on a single iSCSI connection with 512-byte reads.

Realistically, in multi-connection environments focused on
predominantly 4KB (or more) workloads, this concept loses its
effectiveness - it is relatively rare that PDUs from multiple
I/O would coalesce within the default 8us flush timeout period.

There were no users of flush timeout in the SPDK tree - it was
not even documented in the iSCSI configuration file example and
there was no way to modify it at run time.  So leave the change
out of the CHANGELOG.

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.

192.168.1.2/0 would allow hosts from any address, but this is

Netmask prefixes of the full address size (e.g. 32 for IPv4 and 128 for
IPv6) are still allowed, since this represents a valid configuration
that matches a single specific address.

This also allows the IPv4 netmask math to be done entirely in uint32_t
instead of promoting to unsigned long long to avoid undefined behavior
when bits == 0 (shift count would have been 32 in that case).

b65443be6e iscsi: Allow to set cpumask more than active cores for iSCSI connection
Currently the cpumask must be a subset of the reactor mask.

However, this is different from sched_setaffinity() function
and taskset command of FreeBSD and Linux.  The latter will
be familier for more people. Hence the later is adopted.

The following is quoted from the FreeBSD Man Page of taskset:

  The CPU affinity is represented as a bitmask, with the lowest
  order bit corresponding to the first logical CPU and the
  highest order bit corresponding to the last logical CPU.

  Not all CPUs may exist on a given system but a mask may specify
  more CPUs than are present.

  A retrieved mask will reflect only the bits that correspond to
  CPUs physically on the system.

  If an invalid mask is given (i.e., one that corresponds to no
  valid CPUs on the current system) an error is returned.

  The masks are typically given in hexadecimal.

855d8e032a iscsi: change master_lcore to first_core for idle connection management
Currently idle iSCSI connections are managed by the master lcore,
but the master lcore is like BSP of OS and for initialization.

To manage idle iSCSI connections it is important that the core is
consistent.

Hence the first core is better than the master lcore.

In this patch the following are changed together:
- Errors of kqueue() and epoll_create1() are not related with master
  lcore. "master lcore" is removed and errno is added into the log.
- In spdk_iscsi_conn_allocate_reactor(), when cpumask is 0, 0 is
  selected as core number. 0 is not safe and first_core is used instead.

In spdk_iscsi_conn_allocate_reactor(), when first_core is used instead
of master_lcore, we may observe some contradiction in the following
code. But few changes are done in this patch.

In the current implementation we can assume the first lcore is
equal to the master lcore and the following code will be removed
in the subsequent patch.

/*
 * DPDK returns WAIT for the master lcore instead of RUNNING.
 * So we always treat the reactor on master core as RUNNING.
 */
if (i == master_lcore) {
    state = RUNNING;
} else {
    state = rte_eal_get_lcore_state(i);
}

7767990829 iscsi: Unexpected usage of RTE EAL Launch in load balancing
Before removing the DPDK dependency from the iSCSI connection
load balancing, this should be done.

In spdk_iscsi_conn_allocate_reactor(cpumask)

- if any lcore[i]'s state is FINISHED, the caller calls
  rte_eal_wait_lcore(i). But the purpose of rte_eal_wait_lcore()
  is to check if the slave is in a WAIT state before calling
  rte_eal_remote_launch(). The meaning of this usage is not clear.

- If the state of lcore[i] is WAIT or FINISHED, the reactor does
  not run on the lcore[i]. iSCSI connections consist of not reactor
  but poller. Hence selecting lcore[i] with the state WAIT or
  FINISHED does not look correct.

b37d1b60f1 scsi&test/iscsi_tgt: SCSI device == iSCSI name
In the iSCSI specification, the SCSI device name is defined to be
the iSCSI name of the node.

However, when g_spdk_iscsi.nodebase is used, the SCSI device name
is made of the device specific string (the part of IQN after the
colon).

The size of the temporary buffer fullname[MAX_TMPBUF] in
spdk_iscsi_tgt_node_construct() is 1024 and the size of
spdk_scsi_dev.name is 255. The former is larger than the later.

However the max length of IQN, EUI, NAA are 223, 20, and 36,
respectively. All are less than 255.

Hence even if we use fullname as the SCSI device name, no overflow
will occur. Even if fullname is more than 255, strncpy() does not
write more than 255 in spdk_scsi_dev_construct().

Due to the PG-IG map tree, IG-map is added to PG-map.
When PG was deleted first, PG-map was not deleted but PG was
deleted because PG-map has IG-maps.

PG-IG map tree was designed such that when PG was deleted first,
delete all IG-maps belonging to the PG-map, the PG-map, and then

By this change stale pointer which will cause memory leak is

7bcb08c02b iscsi: Load balancing of iSCSI target is not working
When an iSCSI connection is closed, spdk_iscsi_conn_stop_poller()
is called in spdk_iscsi_conn_destruct() or
spdk_iscsi_conn_check_shutdown().

However, through both paths, g_num_connections[] is decremented
twice:
 (1) in spdk_iscsi_conn_stop_poller()
 (2) in spdk_iscsi_conn_free()
This behavior makes g_num_connections[] negative unexpectedly and
for some cases load balancing does not work and the same CPU is
always selected.

How to fix:
spdk_iscsi_conn_stop_poller() is called in the following functions:
- spdk_iscsi_conn_check_shutdown()
- spdk_iscsi_conn_destruct()
- spdk_iscsi_conn_handle_idle().

[Idea 1]
Remove the code to decrement g_num_connections[] from
spdk_iscsi_conn_free().

[Idea 2]
Remove the code to decrement g_num_connections[] from
spdk_iscsi_conn_stop_poller(). Add the code to decrement
g_num_connections[] to __add_idle_conn().

[Idea 1] is simple because just only one line is deleted.

[Idea 2] may be more symmetric than [Idea 1] but to find the right
place to add the code in __add_idle_conn() is not clear and
difficult.

Hence [Idea 1] is proposed.

[Idea 1] may not be the optimal one and more refactoring may be
done.

92a6988676 iscsi: delete global PG tag check from SendTargets
In the Appendix C. SendTargets Operation in the iSCSI Specification
(RFC7143), there is the following description:

  In a Discovery session, a target MUST return all path information
  (IP address-port pairs and Target Portal Group Tags) for the
  targets on the target Network Entity that the requesting
  initiator is authorized to access.

However no description such that Target Portal Group Tag is used
to check authorization of the requesting initiator.

Moreover, according to the iSCSI Specification (RFC7143),
Target Portal Group Tag is unique within an iSCSI Target Node.

  Tarrget Portal Group Tag identifies a portal group within an
  iSCSI node.

However, current SPDK uses Target Portal Group Tag to check
authorization of the requesting initiator by mistake. This
implementation does not have any compatibility with other storage.

Hence delete the code related with Target Portal Group Tag from
SendTargets function.

6bef902ca5 rpc: add default UNIX domain socket listen address
RPC is a default feature required for almost all usages,
so enable RPC by default, but with a UNIX domain socket
for security reasons.

-r can now be used from the command line to specify
an alternative RPC listen address from the default
/var/tmp/spdk.sock.

Remove the Enable parameter from the Rpc config section
but still allow specifying an alternative listen address
using the Listen parameter as an alternative to the
command line option.  This keeps backward compatibility
for this release for anyone using the configuration file
still.

Remove the Rpc sections from all configuration files
that were using them, except for those that specified
alternate TCP ports for multi-process test cases.  We
can fix these later to use an alternate UNIX domain
socket and to use the command line instead.

1e33a802b4 iscsi: fix layout of logout request reason field
The Logout Request reason field is the low 7 bits of byte byte 1; the
last bit of byte 1 is specified to be always 1, and we shouldn't
consider it to be part of the reason field.

The existing debug print code was parsing the reason field correctly (by
masking it against 0x7f), but it's simpler to just make the reason field
into a bitfield of the proper size; this fixes the real bug in the
reqh->reason != 0 check, which did not use the 0x7f mask.

Fixes GitHub issue #198.

40b74cd343 iscsi: optimization of large read process.
This patch move the spdk_iscsi_conn_handle_queued_tasks() to the main
loop of connection poller, make the logic more clear, it will also fix
one issue of hotplug:
for large read command, it has the potential risk:
one task will be split into N subtaks, when primary task return error and
try to send data in pdu, it will call spdk_iscsi_conn_handle_queued_tasks(),
the primary task is pending now, and all the subtasks will return error from
lun layer synchronous, this make the primary task return from the function
spdk_iscsi_transfer_in() after all the other subtaks, but when the N - 1 subtask
return from function spdk_iscsi_transfer_in(), it meet the condition:
primary->bytes_completed == primary->scsi.transfer_len
then it will send response pdu, after this, the primary task return from
spdk_iscsi_transfer_in(), it also meet the condition, so it will also try
to send response pdu, this will make the application run into error.

Rename the existing ahs_data array in the PDU to just "ahs" to minimize
the necessary changes.  We never actually dereference the ahs structure,
so its type is not important. (We can cast it later if we add support
for anything that requires an AHS.)

f66a0c9e34 scsi: pass management function as a parameter
Specify the function as a parameter to spdk_scsi_dev_queue_mgmt_task.
This makes the API clearer by making it explicit that the management
function is required for management tasks.

5343c22f8d iscsi: do not free io channel refs if login failed
When destroying a connection, we need to check if we got to
full feature phase before freeing any io channels.  This is because
the io channels are only allocated as part of a successful login.

The Calsoft iSCSI test suite has tests which will fail login.
Since the test system was just using a malloc backend with memcpy,
so even though a channel was NULL in some cases, it was never used
since the memcpy engine doesn't need it.

This prepares for some future patches which extend the use
of io channels in the bdev layer.

cce22074a7 iscsi: fix ISID interpretation in login requests
The ISID field is a 6-byte field in network (big-endian) byte order.

The previous code was casting the uint8_t isid[6] value into uint64_t,
which was actually casting the address of the first byte of isid (not
the contents of the array), and it was also not correctly converting
byte order.
