Message-ID: <alpine.LFD.2.01.0908150957060.3162@localhost.localdomain> Date: Sat, 15 Aug 2009 10:29:33 -0700 (PDT) From: Linus Torvalds <torvalds@...ux-foundation.org> To: Christoph Thielecke <christoph.thielecke@....de> cc: Eric Paris <eparis@...hat.com>, Andrew Morton <akpm@...ux-foundation.org>, Al Viro <viro@...IV.linux.org.uk>, Linux Kernel Mailing List <linux-kernel@...r.kernel.org>, "Rafael J. Wysocki" <rjw@...k.pl> Subject: Re: kernel bugs 2.6.31-rc6 Christoph, please don't send kernel bug reports just to my personal email address. There are kernel mailing lists, and there are maintainers, and they all want to know about them - not just one person who has a lot to do anyway. Sending them just to me means that unless it's one of "my" areas, not a lot will be done, but also that 'google' etc won't see it and index it. Eric - looks exactly like that bug Mikko reported but couldn't reproduce, bugzilla entry 13729: http://bugzilla.kernel.org/show_bug.cgi?id=13729 it got closed because Mikko says he can't repro it since -rc3, but clearly it should be re-opened. Looks like something 'event' is either incorrectly 'put' twice (so that you end up trying to free it before it's all done), or some corruption of the '&event->private_data_list'. Either way, it's likely a locking error, although an outright refcounting bug is possible. For example, fsnotify_remove_priv_from_event() will remove the private data event from the list, but what if there are _multiple_ entries with the same 'group' entry? If so, it will remove just the first one. So it looks like the bug could trigger if somebody just adds event private data for the same group to the same event twice. Can that happen?
