Bug#751417: (Linux kernel) Bug#751417: linux-image-3.2.0-4-5kc-malta: no SIGKILL after prctl(PR_SET_SECCOMP, 1, ...) on MIPS
-----BEGIN PGP SIGNED MESSAGE-----
> According to the manual page, after calling it with 1 as a second
> argument, any consecutive system calls other than read(), write(),
> _exit() and sigreturn() should result in the delivery of SIGKILL.
> However, under MIPS any consecutive system call behaves as if
> prctl(PR_SET_SECCOMP, 1, ...) was never called.
> I see no check for seccomp on the MIPS syscall 'fast path'. The
> seccomp check appears to be done on the 'slow path' which is used only
> if tracing or audit is also enabled for the task. If I run the above
> program under strace, it is killed as expected.
