Subject: [RFC PATCH 0/5] Add PAX_REFCOUNT overflow protection

These patches are in support of the kernel self-protection effort recently
proposed on kernel-hardening.

The Linux kernel can be better protected against use-after-free exploits.
This patch adds functionality originally found in the PaX project [1] to
protect the kernel against integer overflows affecting kernel reference
counters, a class of bugs that can lead to use-after-free exploits.

Problems arise when reference counters get overflowed.  The existence of a
kernel path in which a reference counter is incremented more than it is
decremented leads to an overflow bug.  This buggy path can be executed until
INT_MAX is reached, at which point further increments will cause the reference
counter to wrap around to 0.  At this point, the kernel will free the counted
object while it still has legitimate users, creating conditions for a
use-after-free exploit to occur.


Patch Details
----------------

These patches were taken from the PaX project's PAX_REFCOUNT feature.  It
applies cleanly to linux-stable/v4.2.6 [2].  I am in the process of rebasing
these patches to linux-next, but wanted to submit them now for general
comments, bikeshedding, etc.

Most of the changes involve users of atomic_t opting out of overflow protection:
many atomic_t users use the type not as a reference counter, but as some type
of statistical counter (packet counters, etc.).


Issues
---------

* The patch is currently based on linux-stable/v4.2.6.  I am in the process of
rebasing it to linux-next and will submit a follow-up patchset soon.

* PAX_REFCOUNT naming: I picked this naming scheme by default.  It will likely
need to change before going upstream.

* When an overflow is detected, SIGKILL is sent to the offending process.
This may be too drastic for an initial upstream submission.  WARN_ON may be
more appropriate until distros have some time to absorb it and report any
unaddressed overflows.

* 0003-pax-opt-out-of-PAX_REFCOUNT-protection.patch is very large.  I
have another patchset in which these patches are split more or less according
to maintainer (except for drivers/) [3].
