    ICYMI RAP bypass for root -> kernel exploits on grsec. I did find the angry grsec/PaX replies entertaining too. Remember when grsec had to pay out a quarter mil because he couldn't handle critique? H/T

    Just read/skimmed your thesis on Linux CFI. Wow. This is great. Many new techniques that have opened up my eyes to the possibilities.

    "Control-Flow Integrity for the Linux kernel: A Security Evaluation" is the work I've done for my Masters thesis where I analyze how the PaX Team's (public) RAP holds up to stop ROP when applied to the Linux kernel. You may want to check out chapter 3.
