Yes, nice. :) I don't see any ordering dependencies here. The only thing I see is a potential for more "work done by kernel before bailing" in the sense that the arg copying will be performed before we check the kernel_read() result. I struggle to see how that might be a problem, and this get us to fewer exec.c exports. Yay! Reviewed-by: Kees Cook <keesc...@chromium.org> -- Kees Cook
