The newly introduced aborted_task TFO callback has to terminate
exchange with QLogic driver, since command is being deleted and
no status will be queued to the driver at a later point.
This patch also moves the burden of releasing one cmd refcount to
the aborted_task handler.
Changed iSCSI aborted_task logic to satisfy the above requirement.

If a new initiator (different WWN) shows up on the same fcport, old
initiator's session is scheduled for deletion. But there is a small
window between it being marked with QLA_SESS_DELETION_IN_PROGRESS
and qlt_unret_sess getting called when new session's commands will
keep finding old session in the fcport map.
This patch drops cmds/tmrs if they find session in the progress of
being deleted.

There are multiple reasons for disabling this:
1. It provides no functional benefit. We pretty much only get a few more
sysfs entries for each port, but all that information is already
available from /sys/kernel/debug/target/qla-session-X
2. It already only works in private-loop mode. By disabling we'll be
getting more uniform behavior with fabric mode.
3. It creates complications for the new PLOGI handling mechanism:
scsi_transport_fc port deletion timer could race with new session
from initiator and cause logout after successful login.

RSCN processing in qla2xxx driver can run in parallel with ELS/IO
processing. As such the decision to remove disappeared fc port's
session could be stale, because a new login sequence has occurred
since and created a brand new session.
Previous mechanism of dealing with this by delaying deletion request
was prone to erroneous deletions if the event that was supposed to
cancel the deletion never arrived or has been delayed in processing.
New mechanism relies on a time-like generation counter to serialize
RSCN updates relative to ELS/IO updates.

QLA_SESS_DELETION_PENDING vs QLA_SESS_DELETION_IN_PROGRESS
- during IN_PROGRESS deletion all newly arrived commands and TMRs will
be rejected, existing commands and TMRs will be terminated when
given by the core to the fabric or simply dropped if session logout
has already happened (logout terminates all existing exchanges)
- new PLOGI will initiate deletion of the following sessions

- different port_name, different loop_id but the same port_id
(with logout)
- different port_name, different port_id, but the same loop_id
(without logout)
- additionally each new PLOGI will store imm notify iocb in the
same port_name session being deleted. When deletion process
completes this iocb will be acked. Only the most recent PLOGI
iocb is stored. The older ones will be terminated when replaced.

Since cmds go into qla_tgt_wq and TMRs don't, it's possible that TMR
like TASK_ABORT can be queued over the cmd for which it was meant.
To avoid this race, use a per-port list to keep track of cmds that
are enqueued to qla_tgt_wq but not yet processed. When a TMR arrives,
iterate through this list and remove any cmds that match the TMR.
This patch supports TASK_ABORT and LUN_RESET.

To fix some issues talking to ESX, this patch modifies the qla2xxx driver
so that it never logs into remote ports. This has the side effect of
getting rid of the "rports" entirely, which means we never log out of
initiators and never tear down sessions when an initiator goes away.
This is mostly OK, except that we can run into trouble if we have
initiator A assigned FC address X:Y:Z by the fabric talking to us, and
then initiator A goes away. Some time (could be a long time) later,
initiator B comes along and also gets FC address X:Y:Z (which is
available again, because initiator A is gone). If initiator B starts
talking to us, then we'll still have the session for initiator A, and
since we look up incoming IO based on the FC address X:Y:Z, initiator B
will end up using ACLs for initiator A.
Fix this by:
1. Handling RSCN events somewhat differently; instead of completely
skipping the processing of fcports, we look through the list, and if
an fcport disappears, we tell the target code the tear down the
session and tell the HBA FW to release the N_Port handle.
2. Handling "port down" events by flushing all of our sessions. The
firmware was already releasing the N_Port handle but we want the
target code to drop all the sessions too.

"It's been a busy development cycle for target-core in a number of
different areas.
The fabric API usage for se_node_acl allocation is now within
target-core code, dropping the external API callers for all fabric
drivers tree-wide.
There is a new conversion to RCU hlists for se_node_acl and
se_portal_group LUN mappings, that turns fast-past LUN lookup into a
completely lockless code-path. It also removes the original
hard-coded limitation of 256 LUNs per fabric endpoint.
The configfs attributes for backends can now be shared between core
and driver code, allowing existing drivers to use common code while
still allowing flexibility for new backend provided attributes.
The highlights include:
- Merge sbc_verify_dif_* into common code (sagi)
- Remove iscsi-target support for obsolete IFMarker/OFMarker
(Christophe Vu-Brugier)
- Add bidi support in target/user backend (ilias + vangelis + agover)
- Move se_node_acl allocation into target-core code (hch)
- Add crc_t10dif_update common helper (akinobu + mkp)
- Handle target-core odd SGL mapping for data transfer memory
(akinobu)
- Move transport ID handling into target-core (hch)
- Move task tag into struct se_cmd + support 64-bit tags (bart)
- Convert se_node_acl->device_list[] to RCU hlist (nab + hch +
paulmck)
- Convert se_portal_group->tpg_lun_list[] to RCU hlist (nab + hch +
paulmck)
- Simplify target backend driver registration (hch)
- Consolidate + simplify target backend attribute implementations
(hch + nab)
- Subsume se_port + t10_alua_tg_pt_gp_member into se_lun (hch)
- Drop lun_sep_lock for se_lun->lun_se_dev RCU usage (hch + nab)
- Drop unnecessary core_tpg_register TFO parameter (nab)

the indirect of inclusion of vmalloc.h by, of all things,
"net/inet_hashtables.h"
None of this got caught during build testing, because on x86
there is an implicit vmalloc.h include via on of the arch asm/
headers.
This fixes all of these

Pull SCSI target updates from Nicholas Bellinger:
"Lots of activity in target land the last months.
The highlights include:
- Convert fabric drivers tree-wide to target_register_template() (hch
+ bart)
- iser-target hardening fixes + v1.0 improvements (sagi)
- Convert iscsi_thread_set usage to kthread.h + kill
iscsi_target_tq.c (sagi + nab)
- Add support for T10-PI WRITE_STRIP + READ_INSERT operation (mkp +
sagi + nab)
- DIF fixes for CONFIG_DEBUG_SG=y + UNMAP file emulation (akinobu +
sagi + mkp)
- Extended TCMU ABI v2 for future BIDI + DIF support (andy + ilias)
- Fix COMPARE_AND_WRITE handling for NO_ALLLOC drivers (hch + nab)
Thanks to everyone who contributed this round with new features,
bug-reports, fixes, cleanups and improvements.
Looking forward, it's currently shaping up to be a busy v4.2 as well"

ipr) plus an assortment of minor updates. There's also a major update to
aic1542 which moves the driver into this millenium.

Instead of calling target_fabric_configfs_init() +
target_fabric_configfs_register() / target_fabric_configfs_deregister()
target_fabric_configfs_free() from every target driver, rewrite the API
so that we have simple register/unregister functions that operate on
a const operations vector.
This patch also fixes a memory leak in several target drivers. Several
target drivers namely called target_fabric_configfs_deregister()
without calling target_fabric_configfs_free().
A large part of this patch is based on earlier changes from
Bart Van Assche <bart.vanassche@sandisk.com>.
(v2: Add a new TF_CIT_SETUP_DRV macro so that the core configfs code
can declare attributes as either core only or for drivers)

For FA-WWPN is enabled port, if NPIV created on that port and,
if port link is brought down, then WWPN was restored from flash for both
physical and NPIV port. This will result in NPIV port and physical port
sharing same WWPN. Any application refreshing ports information will
not be able to scan NPIV port because of this behavior. So while restoring WWPN,
only restore physical port WWPN.

On some vendor switches, when switch port is toggled (down /up),
then in some condition driver tries to configure virtual port,
before FW is actually in ready state to process any commands on wire.
At this time, configuring virtual port can fail. Add fix in driver
to make driver wait, for FW to be ready state before
