Commit f3ddac1918 ("[SCSI] qla2xxx:
Disable adapter when we encounter a PCI disconnect.") has introduced a
code that disables the board, releasing some resources, when reading
0xffffffff.
In case this happens when there is an EEH, this read will trigger EEH
detection and set PCI channel offline. EEH will be able to recover the
card from this state by doing a reset, so it's a better option than
simply disabling the card.
Since eeh_check_failure will mark the channel as offline before
returning the read value, in case there really was an EEH, we can simply
check for pci_channel_offline, preventing the board_disable code from
running if it's true.
Without this patch, EEH code will try to access those same resources
that board_disable will try to free. This race can cause EEH recovery to
fail.

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.

- modify use of sess->deleted flag to differentiate delayed
session deletion that can be cancelled from irreversible one:
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
(unless deletion is already IN_PROGRESS):
- with the same port_name (with logout)
- 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.
- new PRLI will initiate deletion of the following sessions
(unless deletion is already IN_PROGRESS):
- different port_name, different port_id, but the same loop_id
(without logout)

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.

Pull SCSI target updates from Nicholas Bellinger:
"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)

This is the usual grab bag of driver updates (lpfc, hpsa,
megaraid_sas, cxgbi, be2iscsi) plus an assortment of minor updates.
There are also one new driver: the Cisco snic; the advansys driver has
been rewritten to get rid of the warning about converting it to the
DMA API, the tape statistics patch got in and finally, there's a
resuffle of SCSI header files to separate more cleanly initiator from
target mode (and better share the common definitions).

This patch drops unnecessary target_core_fabric_ops parameter usage
for core_tpg_register() during fabric driver TFO->fabric_make_tpg()
se_portal_group creation callback execution.
Instead, use the existing se_wwn->wwn_tf->tf_ops pointer to ensure
fabric driver is really using the same TFO provided at module_init
time.
Also go ahead and drop the forward TFO declarations tree-wide, and
handling the special case for iscsi-target discovery TPG.

iwlwifi/Kconfig and mac80211.h were both trivial overlapping
changes.
The drivers/net/phy/amd-xgbe-phy.c file got removed in 'net-next' and
the bug fix that happened on the 'net' side is already integrated
into the rest of the amd-xgbe driver.
