Hello Tomo-san and all, I've received another report of a list corruption bug causing tgtd to segfault from a customer, and this time with a core file. Here's a screenshot of the debugging session: http://fedorapeople.org/~grover/tgtd-ddd-screenshot.png Some observations: 1) ptr to conn->session->cmd_list is in %rdx. Both the prev pointer and the next ptr (eventually) point to zeroed-out list entries, and leads to segfault. 2) The system's log showed abort_task_set()s and conn_close()s, but none within hours of the segfault. 3) Isn't this a *different* list than was seeing the corruption last time? iscsi_session.cmd_list instead of it_nexus->cmd_list? Strange. Anyway I went over the code again and still don't see a bug, but maybe someone else might see something, or this list corruption might be easier to root-cause than the other one.
