Hm. I'm starting to dislike the dynamic registration the more I think about it. Now when a group is unregistered I'd have to unbind everybody who's currently using it... At least when I want to enforce root/non-root binds which is a further goal. > c) Use a global hash table to store all the genl_multicast_groups; > I think this (handwaving) should be searchable by i) name ii)ID and iii) > family. Also, it doesn't look like I'll ever be searching for a group unless we want to allow userspace to explicitly ask for a group ID, but I'd think it should just get the list of all IDs when asking for family information and then cache that. johannes
