ioctl(fd, WHOAMI, *argp)#

There’s a syscall buried in every UNIX kernel that doesn’t play by the rules. No clean abstractions, no polite interfaces — just a raw channel straight into the guts of the machine. ioctl() is how you talk to device drivers when read() and write() aren’t enough. It’s the trapdoor into ring 0.

This site is a collection of walkthroughs, notes, and things I’ve learned along the way.
