iscsi-target: Add iscsit_transport API template Add basic struct iscsit_transport API template to allow iscsi-target for running with external transport modules using existing iscsi_target_core.h code. For all external modules, this calls try_module_get() and module_put() to obtain + release an external iscsit_transport module reference count. Also include the iscsi-target symbols necessary in iscsi_transport.h to allow external transport modules to function. v3 changes: - Add iscsit_build_reject export for ISTATE_SEND_REJECT usage v2 changes: - Drop unnecessary export of iscsit_get_transport + iscsit_put_transport (roland) - Add ->iscsit_queue_data_in() to remove extra context switch on RDMA_WRITE - Add ->iscsit_queue_status() to remove extra context switch on IB_SEND status - Add ->iscsit_get_dataout() to remove extra context switch on RDMA_READ - Drop ->iscsit_free_cmd() - Drop ->iscsit_unmap_cmd() - Rename iscsit_create_transport() -> iscsit_register_transport() (andy) - Rename iscsit_destroy_transport() -> iscsit_unregister_transport() (andy) Signed-off-by: Nicholas Bellinger <nab@linux-iscsi.org>

iscsi/iser-target: Convert to command priv_size usage This command converts iscsi/isert-target to use allocations based on iscsit_transport->priv_size within iscsit_allocate_cmd(), instead of using an embedded isert_cmd->iscsi_cmd. This includes removing iscsit_transport->alloc_cmd() usage, along with updating isert-target code to use iscsit_priv_cmd(). Also, remove left-over iscsit_transport->release_cmd() usage for direct calls to iscsit_release_cmd(), and drop the now unused lio_cmd_cache and isert_cmd_cache.

iscsi/iser-target: Fix isert_conn->state hung shutdown issues This patch addresses a couple of different hug shutdown issues related to wait_event() + isert_conn->state. First, it changes isert_conn->conn_wait + isert_conn->conn_wait_comp_err from waitqueues to completions, and sets ISER_CONN_TERMINATING from within isert_disconnect_work(). Second, it splits isert_free_conn() into isert_wait_conn() that is called earlier in iscsit_close_connection() to ensure that all outstanding commands have completed before continuing. Finally, it breaks isert_cq_comp_err() into seperate TX / RX related code, and adds logic in isert_cq_rx_comp_err() to wait for outstanding commands to complete before setting ISER_CONN_DOWN and calling complete(&isert_conn->conn_wait_comp_err).

target: Add TFO->abort_task for aborted task resources release Now that TASK_ABORTED status is not generated for all cases by TMR ABORT_TASK + LUN_RESET, a new TFO->abort_task() caller is necessary in order to give fabric drivers a chance to unmap hardware / software resources before the se_cmd descriptor is released via the normal TFO->release_cmd() codepath. This patch adds TFO->aborted_task() in core_tmr_abort_task() in place of the original transport_send_task_abort(), and also updates all fabric drivers to implement this caller. The fabric drivers that include changes to perform cleanup via ->aborted_task() are: - iscsi-target - iser-target - srpt - tcm_qla2xxx The fabric drivers that currently set ->aborted_task() to NOPs are: - loopback - tcm_fc - usb-gadget - sbp-target - vhost-scsi For the latter five, there appears to be no additional cleanup required before invoking TFO->release_cmd() to release the se_cmd descriptor. v2 changes: - Move ->aborted_task() call into transport_cmd_finish_abort (Alex) Cc: Alex Leung <amleung21@yahoo.com> Cc: Mark Rustad <mark.d.rustad@intel.com> Cc: Roland Dreier <roland@kernel.org> Cc: Vu Pham <vu@mellanox.com> Cc: Chris Boot <bootc@bootc.net> Cc: Sebastian Andrzej Siewior <bigeasy@linutronix.de> Cc: Michael S.

iser-target: Fix session reset bug with RDMA_CM_EVENT_DISCONNECTED This patch addresses a bug where RDMA_CM_EVENT_DISCONNECTED may occur before the connection shutdown has been completed by rx/tx threads, that causes isert_free_conn() to wait indefinately on ->conn_wait. This patch allows isert_disconnect_work code to invoke rdma_disconnect when isert_disconnect_work() process context is started by client session reset before isert_free_conn() code has been reached.
