Commit f3ddac1918fe963bcbf8d407a3a3c0881b47248b ("[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.

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)
- Use 64-bit LUNs tree-wide (hannes)
- Drop left-over TARGET_MAX_LUNS_PER_TRANSPORT limit (hannes)"

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.

The only instance of ->put_session is in qla2xxx, and was added by commit
aaf68b ("tcm_qla2xxx: Convert to TFO->put_session() usage") with the following
description:
This patch converts tcm_qla2xxx code to use an internal kref_put() for
se_session->sess_kref in order to ensure that qla_hw_data->hardware_lock
can be held while calling qlt_unreg_sess() for the final put.
But these day we're already holding the hardware lock over qlt_unreg_sess in
the ->close_session callback, so we're fine without this method.

There is just one configfs subsystem in the target code, so we might as
well add two helpers to reference / unreference it from the core code
instead of passing pointers to it around.
This fixes a regression introduced for v4.1-rc1 with commit 9ac8928e6,
where configfs_depend_item() callers using se_tpg_tfo->tf_subsys would
fail, because the assignment from the original target_core_subsystem[]
is no longer happening at target_register_template() time.

FA-WWPN port.
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,

This patch updates qla2xxx target to add a new fabric_prot_type TPG
attribute, used for controlling LLD level protection into LIO when
the backend device does not support T10-PI.
This is required for qla_target.c to enable WRITE_STRIP + READ_INSERT
hardware offloads.
It's disabled by default and controls which se_sesion->sess_prot_type
are set at tcm_qla2xxx_check_initiator_node_acl() session registration
time.

This patch adds the missing TARGET_PROT_ALL when initializing a new
session and declaring the capable se_sess->sup_prot_ops for T10-PI.
This is required in order to function with existing qla_target.c
DIF protection offload support.

This patch fixes the incorrect use of __transport_register_session()
in tcm_qla2xxx_check_initiator_node_acl() code, that does not perform
explicit se_tpg->session_lock when accessing se_tpg->tpg_sess_list
to add new se_sess nodes.
Given that tcm_qla2xxx_check_initiator_node_acl() is not called with
qla_hw->hardware_lock held for all accesses of ->tpg_sess_list, the
code should be using transport_register_session() instead.

This patch exposes a new ../qla2xxx*/$WWPN/$TPGT/dynamic_sessions
attribute to dump the currently active sessions by FC initiator WWPN
that have been created with dynamically generated se_node_acls.
This information is useful so that user-space can optionally perform
dynamic -> explicit NodeACL conversion based on $INITIATOR_WWPN.

logic, and signal VERSION_1 support (MST + Viro + nab)
- Fix iscsi/iser-target to remove problematic active_ts_set usage
(Gavin Guo)
- Update iscsi/iser-target to support multi-sequence sendtargets
(Sagi)
- Fix original PR_APTPL_BUF_LEN 8k size limitation (Martin Svec)
- Add missing WRITE_SAME end-of-device sanity check (Bart)
- Check for LBA + sectors wrap-around in sbc_parse_cdb() (nab)
- Other various minor SPC/SBC compliance fixes based upon Ronnie
Sahlberg test suite (nab)"

Using seq_putc to print a single character saves at least a strlen()
call and a memory access, and may also give a small .text reduction.

Using seq_printf to print a simple string is a lot more expensive than
it needs to be, since seq_puts exists. Replace seq_printf with
seq_puts when possible.
