Deferring decisions to userspace?

Deferring decisions to userspace?

Parent article: Deferring seccomp decisions to user space

The article is titled "Deferring seccomp decisions to user space". As far as I can tell, the referenced patchset doesn't actually defer the whole decision; it allows userspace to synchronously handle the syscall and provide a return value, but userspace can't decide to just let the syscall through, it can only emulate it.

That is a good point, something I didn't mention properly in the article. It behaves a lot like SECCOMP_RET_ERRNO. I have added a little text to try to fill that in, thanks.
