iscsi_target_mod is the only LIO fabric where fabric_ops.name differs from
the fabric_ops.fabric_name string. fabric_ops.name is used when matching
target/$fabric ConfigFS create paths, so rename it .fabric_alias and
fallback to target/$fabric vs .fabric_name comparison if .fabric_alias
isn't initialised. iscsi_target_mod is the only fabric module to set
.fabric_alias . All other fabric modules rely on .fabric_name matching and
can drop the duplicate string.Signed-off-by: David Disseldorp

All fabrics return a const string. In all cases *except* iSCSI the
get_fabric_name() string matches fabric_ops.name.Both fabric_ops.get_fabric_name() and fabric_ops.name are user-facing, with
the former being used for PR/ALUA state and the latter for ConfigFS
(config/target/$name), so we unfortunately need to keep both strings around
for now. Replace the useless .get_fabric_name() accessor function with a
const string fabric_name member variable.Signed-off-by: David Disseldorp

This converts drivers that were only calling transport_deregister_session
to use target_remove_session. The calling of
transport_deregister_session_configfs via target_remove_session for these
types of drivers is ok, because they were not exporting info from fields
like sess_acl_list, sess->se_tpg and sess->fabric_sess_ptr from configfs
accessible functions, so they will see no difference.Signed-off-by: Mike Christie

Rename target_alloc_session to target_setup_session to avoid confusion with
the other transport session allocation function that only allocates the
session and because the target_alloc_session does so much more. It
allocates the session, sets up the nacl and registers the session.The next patch will then add a remove function to match the setup in this
one, so it should make sense for all drivers, except iscsi, to just call
those 2 functions to setup and remove a session.iscsi will continue to be the odd driver.

Target drivers must guarantee that struct se_cmd and struct se_tmr_req
exist as long as target_tmr_work() is in progress. Since the last
access by the LIO core is a call to .check_stop_free() and since the
Xen scsiback .check_stop_free() drops a reference to the TMF, it is
already guaranteed that the struct se_cmd that corresponds to the TMF
exists as long as target_tmr_work() is in progress. Hence change the
second argument of transport_generic_free_cmd() from 1 into 0.Signed-off-by: Bart Van Assche

Turns out the template and thus many drivers got the return value wrong:
0 means the fabrics driver needs to put a session reference, which no
driver except for the iSCSI target drivers did. Fortunately none of these

When adding more than one LUN to a frontend a warning for a failed
assignment is issued in dom0 for each already existing LUN. Avoid this
warning by checking for a LUN already existing when existence is
allowed (scsiback_do_add_lun() called with try == 1).As the LUN existence check is needed now for a third time, factor it
out into a function. This in turn leads to a more or less complete
rewrite of scsiback_del_translation_entry() which will now return a
proper error code in case of failure.Signed-off-by: Juergen Gross

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

still allowing flexibility for new backend provided attributes.The highlights include:

This patch converts the fixed size se_portal_group->tpg_lun_list[]

number of se_lun ports per target endpoint.It includes dropping core_tpg_alloc_lun() from core_dev_add_lun(),

item callback to invoke kfree_rcu() to release memory during
se_lun->lun_group shutdown.Also now that se_node_acl->lun_entry_hlist is using RCU, convert
existing tpg_lun_lock to struct mutex so core_tpg_add_node_to_devs()
can perform RCU updater logic without releasing ->tpg_lun_mutex.Also, drop core_tpg_clear_object_luns() and it's single consumer
in iscsi-target, which is duplicating TPG LUN shutdown logic and
is current code results in a NOP.Finally, sbp-target and xen-scsiback fabric driver conversions are
