target: add a new add_wwn_groups fabrics method

2016-03-31T03:06:44Z

We need to have the WWN fully initialized before addig default groups to it, so add a new method to add these groups after the WWN has been initialized. Also remove the default groups in the core while we're at it. Signed-off-by: Christoph Hellwig Signed-off-by: Nicholas Bellinger

target: Fix target_release_cmd_kref shutdown comp leak

2016-03-22T07:23:08Z

This patch fixes an active I/O shutdown bug for fabric drivers using target_wait_for_sess_cmds(), where se_cmd descriptor shutdown would result in hung tasks waiting indefinitely for se_cmd->cmd_wait_comp to complete(). To address this bug, drop the incorrect list_del_init() usage in target_wait_for_sess_cmds() and always complete() during se_cmd target_release_cmd_kref() put, in order to let caller invoke the final fabric release callback into se_cmd->se_tfo->release_cmd() code.

target: Avoid DataIN transfers for non-GOOD SAM status

2016-03-11T06:36:12Z

This patch modifies existing transport_complete_*() code to avoid invoking target_core_fabric_ops->queue_data_in() driver callbacks for I/O READs with non-GOOD SAM status. Some initiators expect GOOD status when a DATA-IN payload transfer is involved, so to be safe go ahead and always invoke target_core_fabric_ops->queue_status() to generate fabric responses instead. Note this is a prerequisite for IBLOCK supporting retriable status, so SAM_STAT_BUSY + SAM_STAT_TASK_SET_FULL always generates fabric driver responses instead of initiating DataIN payload transfer when non-GOOD status is present Reviewed-by: Christoph Hellwig Cc: Hannes Reinecke Cc: Sagi Grimberg Cc: Andy Grover Cc: Mike Christie Signed-off-by: Nicholas Bellinger
