target: Add link_magic for fabric allow_link destination target_items

2013-01-21T19:45:24Z

commit 0ff8754981261a80f4b77db2536dfea92c2d4539 upstream. This patch adds [dev,lun]_link_magic value assignment + checks within generic target_fabric_port_link() and target_fabric_mappedlun_link() code to ensure destination config_item *target_item sent from configfs_symlink() -> config_item_operations->allow_link() is the underlying se_device->dev_group and se_lun->lun_group that we expect to symlink.

target: Add generation of LOGICAL BLOCK ADDRESS OUT OF RANGE

2012-08-09T15:31:26Z

commit e2397c704429025bc6b331a970f699e52f34283e upstream. Many SCSI commands are defined to return a CHECK CONDITION / ILLEGAL REQUEST with ASC set to LOGICAL BLOCK ADDRESS OUT OF RANGE if the initiator sends a command that accesses a too-big LBA. Add an enum value and case entries so that target code can return this status. Signed-off-by: Roland Dreier Signed-off-by: Nicholas Bellinger Signed-off-by: Greg Kroah-Hartman

target: Use array_zalloc for device_list

2012-03-16T02:15:51Z

Turns an order-8 allocation into slab-sized ones, thereby preventing allocation failures with memory fragmentation. This likely saves memory as well, as the slab allocator can pack objects more tightly than the buddy allocator.

target: Use array_zalloc for tpg_lun_list

2012-03-16T02:15:38Z

Turns an order-10 allocation into slab-sized ones, thereby preventing allocation failures with memory fragmentation. This likely saves memory as well, as the slab allocator can pack objects more tightly than the buddy allocator. Signed-off-by: Joern Engel Signed-off-by: Nicholas Bellinger

target: Bump core version to v4.1.0-rc2-ml + fabric versions

2012-03-10T22:55:17Z

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 Signed-off-by: Nicholas Bellinger

target: Drop unused legacy target_core_fabric_ops API callers

2012-03-10T22:42:55Z

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.

target: Convert se_node_acl->acl_group removal to use ->acl_kref

2012-03-10T22:42:19Z

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.

target: Add se_node_acl->acl_kref for ->acl_free_comp usage

2012-03-10T22:42:09Z

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 Cc: Christoph Hellwig Cc: Joern Engel Cc: Andy Grover Signed-off-by: Nicholas Bellinger

target: Add se_node_acl->acl_free_comp for NodeACL release path

2012-03-10T22:41:59Z

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.

target: Add se_sess->sess_kref + get/put helpers

2012-03-10T22:41:53Z

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.
