[PATCH 0/3] target: Fix two races leading to use-after-free

From: Joern Engel
Date: Mon May 13 2013 - 17:58:50 EST


In our testing we've encountered use-after-free bugs, usually in the
shape of double list_del, at a rate of 2-10 per week. Patches 2 and 3
fix two races that can both lead to use-after-free and after applying
both of those patches, we have been bug-free for some weeks now.

Patch 1 is an unrelated trivial cleanup. I just happened to spot it
while I was in the area.

Joern Engel (3):
target: removed unused transport_state flag
target: close target_put_sess_cmd() vs. core_tmr_abort_task() race v5
target: simplify target_wait_for_sess_cmds()
