I don't want to speak for Blaise (or James for that matter), but my
understanding is that Hornet is focused on ensuring BPF program
integrity at load time; similar to KP's signature scheme which has
recently found its way into Linus tree.  Where KP's and Blaise's
scheme differ is in how they perform the integrity checks.
