scsi: target: core: De-RCU of se_lun and se_lun acl

2022-08-01T23:36:02+00:00

se_lun and se_lun_acl are immutable pointers of struct se_dev_entry.
Remove RCU usage for access to those pointers.

scsi: target: Add callout to configure UNMAP settings

2022-07-07T20:53:52+00:00

Add a callout to configure a backend's UNMAP settings. This will be used to
allow userspace to configure UNMAP after the initial device setup, similar
to how we can set up the other attributes post device configuration.

scsi: target: iscsi: Control authentication per ACL

2022-06-08T01:55:11+00:00

Add acls/{ACL}/attrib/authentication attribute that controls authentication
for particular ACL. By default, this attribute inherits a value of the
authentication attribute of the target port group to keep backward
compatibility.

Authentication attribute has 3 states:

 "0" - authentication is turned off for this ACL

 "1" - authentication is required for this ACL

 "-1" - authentication is inherited from TPG

scsi: target: iscsi: Add upcast helpers

2022-06-08T01:55:11+00:00

iSCSI target is cluttered with open-coded container_of() conversions from
se_nacl to iscsi_node_acl. The code could be cleaned by introducing a
helper - to_iscsi_nacl() (similar to other helpers in target core).

While at it, make another iSCSI conversion helper consistent and rename
iscsi_tpg() helper to to_iscsi_tpg().

Pull SCSI updates from James Bottomley:
 "This consists of a small set of driver updates (lpfc, ufs, mpt3sas
  mpi3mr, iscsi target). Apart from that this is mostly small fixes with
  very few core changes (the biggest one being VPD caching)"

scsi: target: Add iscsi/cpus_allowed_list in configfs

2022-03-15T03:40:36+00:00

The RX/TX threads for iSCSI connection can be scheduled to any online CPUs,
and will not be rescheduled.

When binding other heavy load threads along with iSCSI connection RX/TX
thread to the same CPU, the iSCSI performance will be worse.

Add iscsi/cpus_allowed_list in configfs. The available CPU set of iSCSI
connection RX/TX threads is allowed_cpus & online_cpus. If it is modified,
all RX/TX threads will be rescheduled.
