Subject: [PATCH 0/2] IPC DoS fix
Date: Sat,  2 Nov 2013 22:26:37 +0100	[thread overview]
Message-ID: <1383427599-1980-1-git-send-email-minipli@googlemail.com> (raw)

Hi Linus,

this series fixes a bug in the IPC code that allows root to instantly crash
the system. The first patch fixes the bug, the second one prevents msgmax
from getting negative in the first place. As that *might* break existing
userspace (for good?!) it's a separate patch.

The cc list is quite randomly choosen as there seem to be no maintainer for
ipc/. :/

Please apply!
