Tom, this is just a wolf in sheep's clothing. It's still a cache controllable by external entities. It still therefore has the DoS'ability aspects. You can keep reframing this thing you want out there, either by explicitly filling the cache in the kernel or doing it via userspace responding the netlink events, but it's still the same exact thing with the same set of problems. I'm sorry, but I can't apply this series. Nor any series that adds a DoS'able facility of forwarding/switching/route objects to the kernel. Thanks.
