2012-03-10target: Bump core version to v4.1.0-rc2-ml + fabric versionsNicholas Bellinger

2012-03-10tcm_fc: Fix fc_exch memory leak in ft_send_resp_statusNicholas Bellinger
This patch fixes a bug in tcm_fc where fc_exch memory from fc_exch_mgr->ep_pool is currently being leaked by ft_send_resp_status() usage. Following current code in ft_queue_status() response path, using lport->tt.seq_send() needs to be followed by a lport->tt.exch_done() in order to release fc_exch memory back into libfc_em kmem_cache. ft_send_resp_status() code is currently used in pre submit se_cmd ft_send_work() error exceptions, TM request setup exceptions, and main TM response callback path in ft_queue_tm_resp(). This bugfix addresses the leak in these cases.

2012-03-10target: Drop unused legacy target_core_fabric_ops API callersNicholas Bellinger
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.

2012-03-10iscsi-target: Convert to use target_put_session + sess_krefNicholas Bellinger
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. (v2: Make iscsit_handle_time2retain_timeout() use target_put_session) Cc: Andy Grover <agrover@redhat.com> Cc: Christoph Hellwig <hch@lst.de> Signed-off-by: Nicholas Bellinger <nab@linux-iscsi.org>
2012-03-10target: Convert se_node_acl->acl_group removal to use ->acl_krefNicholas Bellinger
This patch converts core_tpg_del_initiator_node_acl() shutdown from configfs context to use se_node_acl->acl_kref and ->acl_free_comp in order to wait for outstanding fabric callbacks to complete via transport_deregister_session() callbacks before waking ->acl_free_comp from the last ->acl_kref put. It also changes core_tpg_del_initiator_node_acl() to setup a local sess_list with target_get_session() + acl->acl_stop = 1 for active sessions that will be shutdown, and changes transport_deregister_session_configfs() to check for ->acl_stop usage.

2012-03-10target: Add se_node_acl->acl_kref for ->acl_free_comp usageNicholas Bellinger
This patch adds se_node_acl->acl_kref for use with ->acl_free_comp during explict se_node_acl release. It adds kref_init() during se_node_acl setup, kref_get() during __transport_register_session() -> target_put_nacl() with existing transport_deregister_session() fabric callback usage. It also moves transport_free_session() to release *se_sess memory after target_put_nacl() execution in transport_deregister_session() Cc: Roland Dreier <roland@purestorage.com> Cc: Christoph Hellwig <hch@lst.de> Cc: Joern Engel <joern@logfs.org> Cc: Andy Grover <agrover@redhat.com> Signed-off-by: Nicholas Bellinger <nab@linux-iscsi.org>
2012-03-10target: Add se_node_acl->acl_free_comp for NodeACL release pathNicholas Bellinger
Add se_node_acl->acl_free_comp for NodeACL release path to wait for outstanding fabric session shutdown to complete in transport_deregister_session() before finishing NodeACL release from configfs process context. Also make transport_deregister_session() clear the comp_nacl bit to skip se_node_acl->acl_free_comp completion for dynamically generated NodeACL during fabric session shutdown.

2012-03-10target: Add se_sess->sess_kref + get/put helpersNicholas Bellinger
This patch adds basic se_session->sess_kref and get/put helpers for fabric session reference counting. It sets the initial kref in transport_init_session() and adds a target_release_session() callback to invoke TFO->close_session() for final session shutdown.

2012-03-10target: Convert session_lock to irqsaveNicholas Bellinger
This patch converts the remaining struct se_portal_group->session_lock usage to use irqsave+irqrestore to address the following warnings for hardware target mode interrupt context usage. This change generate other warnings for current iscsi-target mode still using ->session_lock with spin_lock_bh, which will need to be converted in a seperate patch.
