Synthetic Memory Protections - An update on ROP mitigations
https://www.openbsd.org/papers/csw2023.pdf [www.openbsd.org]

ROP methods have become increasingly sophisticated
But we can identify system behaviours which only ROP code requires
We can contrast this to what Regular Control Flow code needs
And then, find behaviours to block

Fuzzing the OpenBSD Kernel

Fuzzing the OpenBSD kernel using the syzkaller kernel fuzzer.
kcov(4)
A driver for tracking kernel code coverage.
Enabled on a per thread basis.
The kernel program counter is tracked during syscalls made by the same thread.
Not a strict requirement for syzkaller but improves its ability to generate interesting programs.
