Pull SCSI target updates from Nicholas Bellinger:
 "This contains the usual set of updates and bugfixes to target-core +
  existing fabric module code, along with a handful of the patches
  destined for v3.3 stable.

  It also contains the necessary target-core infrastructure pieces
  required to run using tcm_qla2xxx.ko WWPNs with the new Qlogic Fibre
  Channel fabric module currently queued in target-pending/for-next-merge,
  and coming for round 2.

  The highlights for this series include:

   - Add target_submit_tmr() helper function for fabric task management
     (andy)
   - Convert tcm_fc to use target_submit_tmr() (andy)
   - Replace target core various cmd flags with a transport state (hch)
   - Convert loopback to use workqueue submission (hch)
   - Convert target core to use array_zalloc for tpg_lun_list (joern)
   - Convert target core to use array_zalloc for device_list (joern)
   - Add target core support for TMR_ABORT_TASK (nab)
   - Add target core se_sess->sess_kref + get/put helpers (nab)
   - Add target core se_node_acl->acl_kref for ->acl_free_comp usage
     (nab)
   - Convert iscsi-target to use target_put_session + sess_kref (nab)
   - Fix tcm_fc fc_exch memory leak in ft_send_resp_status (nab)
   - Fix ib_srpt srpt_handle_cmd send_ioctx->ioctx_kref leak on
     exception (nab)
   - Fix target core up handling of short INQUIRY buffers (roland)
   - Untangle target-core front-end and back-end meanings of max_sectors
     attribute (roland)
   - Set loopback residual field for SCSI commands (roland)
   - Fix target-core 16-bit target ports for SET TARGET PORT GROUPS
     emulation (roland)

  Thanks again to Andy, Christoph, Joern, Roland, and everyone who has
  contributed this round!"

Pull security subsystem updates for 3.4 from James Morris:
 "The main addition here is the new Yama security module from Kees Cook,
  which was discussed at the Linux Security Summit last year.  Its
  purpose is to collect miscellaneous DAC security enhancements in one
  place.  This also marks a departure in policy for LSM modules, which
  were previously limited to being standalone access control systems.
  Chromium OS is using Yama, and I believe there are plans for Ubuntu,
  at least.

  This patchset also includes maintenance updates for AppArmor, TOMOYO
  and others."

Fix trivial conflict in <net/sock.h> due to the jumo_label->static_key
rename.

Get rid of a bunch of write-only variables.  In a number of cases I
suspect actual bugs to be present, so I left all of those for a second
look.

This patch addresses a iscsi-target specific bug related to reservation conflict
handling in iscsit_handle_scsi_cmd() that has been causing reservation conflicts
to complete and not fail as expected due to incorrect errno checking.  The problem
occured with the change to return -EBUSY from transport_generic_cmd_sequencer() ->
transport_generic_allocate_tasks() failures, that broke iscsit_handle_scsi_cmd()
checking for -EINVAL in order to invoke a non GOOD status response.

This was manifesting itself as data corruption with legacy SPC-2 reservations,
but also effects iscsi-target LUNs with SPC-3 persistent reservations.

This bug was originally introduced in lio-core commit:

Bump core version to v4.1.0-rc2-ml, and for versions from the
following mainline fabric modules:

loopback: v2.1-rc2
tcm_fc: v0.4
iscsi-target: v4.1.0-rc2

This patch drops the following unused legacy API callers from target_core_fabric.h:

*) TFO->fall_back_to_erl0()
*) TFO->stop_session()
*) TFO->sess_logged_in()
*) TFO->is_state_remove()

This patch also removes the stub usage in loopback, tcm_fc, iscsi_target,
and ib_srpt fabric modules.

This patch converts iscsi-target session code to use se_sess->sess_kref
counting for iscsi session shutdown.  The following cases include:

*) last iscsit_close_connection() shutdown path to invoke close session
*) iscsit_logout_post_handler_closesession() for explict logout
*) iscsit_free_session() caller for explict shutdown

It also moves iscsit_stop_session() call from lio_tpg_close_session()
into lio_tpg_shutdown_session() TFO callbacks to invoke an explict
shutdown, and also changes iscsi_check_for_session_reinstatement()
login code to use se_sess->sess_kref.
