The aim of this is to implement pledge on linux using seccomp rules.

seccomp supports filtering syscalls in a way that isn't vulnerable to race conditions (as ptrace is).


The design and structure of the code is complete (parses the pledge string correctly, builds up a a bitmask using flags, adds rules for each flag), all that's left is filling in each of the promise sections with all the syscalls that are needed, and testing them.
