* target: Add TMR_ABORT_TASK task management supportNicholas Bellinger2012-02-253-7/+79
| | | | | | | | | | | | | | | | | | | | This patch adds initial support for TMR_ABORT_TASK ops for se_cmd descriptors using se_sess->sess_cmd_list and se_cmd->cmd_kref counting. It will perform an explict abort for all outstanding se_cmd ops based upon tmr->ref_task_tag that have not been set CMD_T_COMPLETE. It will cancel se_cmd->work and wait for backing I/O to complete before attempting to send SAM_STAT_TASK_ABORTED and perform target_put_sess_cmd() to release the referenced descriptor. It also adds a CMD_T_ABORTED check into transport_complete_task() to catch the completion from backend I/O that has been aborted, and updates transport_wait_for_tasks() to allow CMD_T_ABORTED usage with core_tmr_abort_task() context.

* target: Make target_release_cmd_kref release on empty listNicholas Bellinger2012-02-251-1/+1
| | | | | | | | | | | This patch changes target_release_cmd_kref() to make TFO->release_cmd() call when list_empty(&se_cmd->se_cmd_list) is TRUE. This is required for TMR_ABORT_TASK operation where the referenced tag descriptor may have already been pulled of the session command list.

| | | | | | | | | | | When TARGET_SCF_ACK_KREF is in use with target_submit_cmd() for setting the extra acknowledgement reference to se_cmd->cmd_kref, go ahead and set SCF_ACK_KREF in order to be used later by abort task.

* target: Export transport_generic_request_failure symbolNicholas Bellinger2012-02-252-2/+3
| | | | | | | | | | | | | | transport_generic_request_failure() is a wrapper around calling transport_send_check_condition_and_sense() that is required once an se_cmd->cmd_kref has been obtained via target_submit_cmd() -> target_get_sess_cmd(). tcm_qla2xxx currently requires this, and since it's necessary for other callers using target_submit_cmd() make it exportable now.

* target: Cleanup transport_kunmap_data_sg()Andy Grover2012-02-251-2/+4
| | | | | | | | | | | | This code isn't broken per se, but it's scary to look at! It looks like in the t_data_nents==1 case we're doing both a kunmap and a vunmap, what's saving us is that t_data_vmap in this case is 0, so vunmap doesn't do anything. Return after kunmap, so the handling of the three cases does not overlap. Signed-off-by: Andy Grover <agrover@redhat.com> Signed-off-by: Nicholas Bellinger <nab@linux-iscsi.org>

* target: increase iblock task sizesChristoph Hellwig2012-02-252-17/+37
| | | | | | | | | | | | | | | | There is no real limit for task sizes in the iblock driver given that we can chain bios. Increase the maximum size to UINT_MAX, and change the code to submit bios in a smaller batch size to avoid deadlocks when having more bios in flight than the pool supports. Also increase the pool size to always allow multiple tasks to be in flight. I also had to change the task refcounting to include one reference for the submission task, which is a standard practice in this kind of code in Linux (e.g. XFS I/O submission).

| | | | | | | | | | | | | | Replace various atomic_ts used as flags in struct se_cmd with a single transport_state bitmap that requires t_state_lock to be held for modifications. In the target core that assumption generally is true, but some recently added code in the SRP target had to grow new lock calls. I can't say I like the way how it messes with the command state directly, but let's leave that for later. (Re-add missing ib_srpt.c changes that nab dropped..)
