Ok, so we probably won't focus on b) as a priority right now, unless it happens as a side-effect. > I don't really have any concrete ideas about what a better > interface would look like. But I am more than happy to hash our ideas. Good! At the moment I'm looking at various netlink docs and figuring out how things generally work. I think netlink probably adds a lot of complexity over the previous sockopt interface, but I hope it's worth it. As for compatibility and extensibility, how is that best achieved with netlink? I've seen some examples copy whole C structs into netlink datagrams, but that is obviously what we don't want anymore. So the way to go seems to be to transfer each struct field as a separate netlink attribute, right?
