[PATCH v3 0/4] arch/arm: support seccomp

From: Kees Cook
Date: Thu Nov 01 2012 - 20:16:15 EST


This adds support for seccomp BPF to ARM. When built with the seccomp
improvement patch waiting in linux-next ("seccomp: Make syscall skipping
and nr changes more consistent"), this passes the seccomp regression
test suite: https://github.com/redpig/seccomp

Thanks,

-Kees

v3:
- updates suggested by Russell King:
- reduced scope of expansion
- leveraged TIF_SYSCALL_WORK bit mask
- fixed syscall==-1 short-circuit logic

v2:
- expanded ptrace_syscall_trace() into both callers and do
secure_computing() hookup there, as requested by Al Viro.
