  • OpenBSD: viable ROP-free roadmap for i386/armv8/riscv64/alpha

    From Oliver Kennedy@21:1/5 to All on Fri Sep 29 01:13:43 2023
    RETGUARD provides up to 4096 cookies per DSO, per-function, but limited to
    avoid excessive bloat. It is difficult to do on architectures with very few
    registers. Code was only written for clang, there is no gcc codebase doing
    it. clang code for some architectures was never written (riscv64).
