Revision 47b1584c1c95f0bb4d646c47de1c0455bb5cef54 authored by Alex Leung on 04 April 2014, 04:38:19 UTC, committed by Nicholas Bellinger on 11 April 2014, 22:27:15 UTC
This patch addresses an issue that occurs when an ABTS is received for an se_cmd that completes just before the sess_cmd_list is searched in core_tmr_abort_task(). When the sess_cmd_list is searched, since the ABTS and the FCP_CMND being aborted (that just completed) both have the same OXID, TFO->get_task_tag(TMR) returns a value that matches tmr->ref_task_tag (from TFO->get_task_tag(FCP_CMND)), and the Abort Task tries to abort itself. When this occurs, transport_wait_for_tasks() hangs forever since the TMR is waiting for itself to finish. This patch adds a check to core_tmr_abort_task() to make sure the TMR does not attempt to abort itself.
