Subject: apparmor: double lock
Date: Sat, 04 Sep 2010 13:57:13 +0200 [thread overview]
Message-ID: <4C823419.6050906@gmail.com> (raw)
Hi,
stanse found that you possibly double lock ns->lock:
aa_remove_profiles
-> write_lock(&ns->lock)
-> __remove_namespace(ns)
-> destroy_namespace(ns)
-> write_lock(&ns->lock)
Could you fix that if that may happen at all?
regards,
