Hmm, if anything then not the connectivity but rather the MLME i.e. it won't do roaming properly maybe. Maybe we should then have a way to say that somebody only wants to receive messages from privileged users, that way the MLME process wouldn't be affected. > I'm not sure, it would probably also have to be called when userspace > unsubscribes from a group, no? No actually having that hook means I can do without multicast groups by just publishing that "send configuration requests to pid N" where N is either 0 (in-kernel MLME) or something else (userspace MLME); I just didn't know the hook existed. Not that we shouldn't fix the multicast issues anyway though the one from this particular thread wouldn't be too interesting right now until somebody needs userspace to multicast; the other three patches still should be done now before there are more generic netlink multicast users. johannes
