Subject: [PATCH 0/2] IPC DoS fix

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!


Mathias Krause (2):
  ipc, msg: fix message length check for negative values
  ipc, msg: forbid negative values for "msgmax"
