Hi Will, That's very different approach to the system call interposition problem. I find you solution very interesting. It gives far more capabilities than my syscalls cgroup that you commented on some time ago. It's ready now but I haven't tried filtering yet. I think that if your solution make it to the mainline (and I guess that's really possible at current stage :)), there will be no place for mine solution but that's ok. There's one thing that I'm curious about - have you measured overhead in any way? That was one of the biggest issues in all previous attempts to limit syscalls. I'd love to compare the numbers with mine solution. I'll examine your patch later on and put some comments if I bump into something.
