    Flood pinging is a policy issue. We don't want just anybody flood ping so
    it checks that the ruid is 0. May I ask exactly what went wrong with

    Your patch doesn't handle notes of different types if I'm reading it
    correctly and it must be first note . I'll look into how the elf stuff
    works closer and what kinds of information and sanity checks we can do so
    that the kmalloc isn't a DoS problem. I'll relook into both versions of
    the elfcap note finder stuff. It's definately 2.3ish though.

    Any caps I mention are *derived* from a withdrawn draft posix document.
