- keep qla_tgt_sess object on the session list until it's freed - modify use of sess->deleted flag to differentiate delayed session deletion that can be cancelled from irreversible one: QLA_SESS_DELETION_PENDING vs QLA_SESS_DELETION_IN_PROGRESS - during IN_PROGRESS deletion all newly arrived commands and TMRs will be rejected, existing commands and TMRs will be terminated when given by the core to the fabric or simply dropped if session logout has already happened (logout terminates all existing exchanges) - new PLOGI will initiate deletion of the following sessions (unless deletion is already IN_PROGRESS): - with the same port_name (with logout) - different port_name, different loop_id but the same port_id (with logout) - different port_name, different port_id, but the same loop_id (without logout) - additionally each new PLOGI will store imm notify iocb in the same port_name session being deleted. When deletion process completes this iocb will be acked. Only the most recent PLOGI iocb is stored. The older ones will be terminated when replaced. - new PRLI will initiate deletion of the following sessions (unless deletion is already IN_PROGRESS): - different port_name, different port_id, but the same loop_id (without logout) Cc: <stable@vger.kernel.org> # v3.18+ Signed-off-by: Alexei Potashnik <alexei@purestorage.com> Acked-by: Quinn Tran <quinn.tran@qlogic.com> Signed-off-by: Himanshu Madhani <himanshu.madhani@qlogic.com> Signed-off-by: Nicholas Bellinger <nab@linux-iscsi.org>

Since cmds go into qla_tgt_wq and TMRs don't, it's possible that TMR like TASK_ABORT can be queued over the cmd for which it was meant. To avoid this race, use a per-port list to keep track of cmds that are enqueued to qla_tgt_wq but not yet processed. When a TMR arrives, iterate through this list and remove any cmds that match the TMR. This patch supports TASK_ABORT and LUN_RESET.

To fix some issues talking to ESX, this patch modifies the qla2xxx driver so that it never logs into remote ports. This has the side effect of getting rid of the "rports" entirely, which means we never log out of initiators and never tear down sessions when an initiator goes away. This is mostly OK, except that we can run into trouble if we have initiator A assigned FC address X:Y:Z by the fabric talking to us, and then initiator A goes away. Some time (could be a long time) later, initiator B comes along and also gets FC address X:Y:Z (which is available again, because initiator A is gone). If initiator B starts talking to us, then we'll still have the session for initiator A, and since we look up incoming IO based on the FC address X:Y:Z, initiator B will end up using ACLs for initiator A. Fix this by: 1. Handling RSCN events somewhat differently; instead of completely skipping the processing of fcports, we look through the list, and if an fcport disappears, we tell the target code the tear down the session and tell the HBA FW to release the N_Port handle. 2. Handling "port down" events by flushing all of our sessions. The firmware was already releasing the N_Port handle but we want the target code to drop all the sessions too.

Commit 835a6a2f ("Bluetooth: Stop sabotaging list poisoning") thought that the code was sabotaging the list poisoning when NULL'ing out the list pointers and removed it. But what was going on was that the bluetooth code was using NULL pointers for the list as a way to mark it empty, and that commit just broke it (and replaced the test with NULL with a "list_empty()" test on a uninitialized list instead, breaking things even further). So fix it all up to use the regular and real list_empty() handling (which does not use NULL, but a pointer to itself), also making sure to initialize the list properly (the previous NULL case was initialized implicitly by the session being allocated with kzalloc()) This is a combination of patches by Marcel Holtmann and Tedd Ho-Jeong An.

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 drivers tree-wide. There is a new conversion to RCU hlists for se_node_acl and se_portal_group LUN mappings, that turns fast-past LUN lookup into a completely lockless code-path. It also removes the original hard-coded limitation of 256 LUNs per fabric endpoint. The configfs attributes for backends can now be shared between core and driver code, allowing existing drivers to use common code while still allowing flexibility for new backend provided attributes. The highlights include: - Merge sbc_verify_dif_* into common code (sagi) - Remove iscsi-target support for obsolete IFMarker/OFMarker (Christophe Vu-Brugier) - Add bidi support in target/user backend (ilias + vangelis + agover) - Move se_node_acl allocation into target-core code (hch) - Add crc_t10dif_update common helper (akinobu + mkp) - Handle target-core odd SGL mapping for data transfer memory (akinobu) - Move transport ID handling into target-core (hch) - Move task tag into struct se_cmd + support 64-bit tags (bart) - Convert se_node_acl->device_list[] to RCU hlist (nab + hch + paulmck) - Convert se_portal_group->tpg_lun_list[] to RCU hlist (nab + hch + paulmck) - Simplify target backend driver registration (hch) - Consolidate + simplify target backend attribute implementations (hch + nab) - Subsume se_port + t10_alua_tg_pt_gp_member into se_lun (hch) - Drop lun_sep_lock for se_lun->lun_se_dev RCU usage (hch + nab) - Drop unnecessary core_tpg_register TFO parameter (nab) - Use 64-bit LUNs tree-wide (hannes) - Drop left-over TARGET_MAX_LUNS_PER_TRANSPORT limit (hannes)" * 'for-next' of git://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending: (76 commits) target: Bump core version to v5.0 target: remove target_core_configfs.h target: remove unused TARGET_CORE_CONFIG_ROOT define target: consolidate version defines target: implement WRITE_SAME with UNMAP bit using ->execute_unmap target: simplify UNMAP handling target: replace se_cmd->execute_rw with a protocol_data field target/user: Fix inconsistent kmap_atomic/kunmap_atomic target: Send UA when changing LUN inventory target: Send UA upon LUN RESET tmr completion target: Send UA on ALUA target port group change target: Convert se_lun->lun_deve_lock to normal spinlock target: use 'se_dev_entry' when allocating UAs target: Remove 'ua_nacl' pointer from se_ua structure target_core_alua: Correct UA handling when switching states xen-scsiback: Fix compile warning for 64-bit LUN target: Remove TARGET_MAX_LUNS_PER_TRANSPORT target: use 64-bit LUNs target: Drop duplicate + unused se_dev_check_wce target: Drop unnecessary core_tpg_register TFO parameter ...
