Blue DeviL // SCTA very detailed tutorial from "Joaquin Pinillos"
Walk x86-64 page tables by hand in qemu and gdb. Decompose a virtual address, follow cr3 through all levels of physical memory, and extract a flag from raw bytes.
@netbsd thanks for explainint. then why does a simple "gcc foo.c -o foo" have different security features enabled on NetBSD, FreeBSD, Linux? (no pkgsrc, Makefile or mk/* involved)
I guess having one big switch somewhere in gcc for all of NetBSD's platform would be challenging. Is this kept on the least common denominator on purpose?
