You appear to be quoting[1], but you left off a bit.  To edit it a bit:

  "Use a security module, either by using something like SELinux (...),
  or write your own little security module that does it."

I have done the latter.

I don't need to integrate this into grsecurity because grsecurity already
has these protections.  It is Openwall and grsecurity that I'm using as the
starting point for this attempt at upstreaming the protections.
