Subject: [PATCH v4 0/3] net: unix: fix use-after-free
Date: Fri, 9 Oct 2015 00:15:59 -0400 [thread overview]
Message-ID: <cover.1444363559.git.jbaron@akamai.com> (raw)
Hi,
These patches are against mainline, I can re-base to net-next, please
let me know.
They have been tested against: https://lkml.org/lkml/2015/9/13/195,
which causes the use-after-free quite quickly and here:
https://lkml.org/lkml/2015/10/2/693.
Thanks,
-Jason
