For starters, the upstream developer claims [1, 2] to engage in the
morally reprehensible practice of selling 0-day exploits he finds in
competing products to blackhats. This also casts doubt on the
trustworthiness of his *own* code, since any undiscovered (read: not
publicly disclosed) vulnerabilities/holes/etc in Grsecurity are a
potential revenue stream for him. Not that my opinion carries much
weight, but I personally feel that this massive conflict of interest
means that Grsecurity should never be supported by Debian in any way

their own code? If so, how much would RedHat pay for information on an
information leaking vulnerability in SELinux for a physical, local
user? I've sold all my Exec-Shield exploits (that still work!),
otherwise I'd offer those as well ;\"
