[snip] Self-NAK, my torture tests uncovered (a rather obvious) locking issue with the dump code. The src groups will have to be traversed with RCU, and thus RCU-friendly since the mdb dump code doesn't acquire multicast_lock and we don't want to block IGMP processing. I'll wait with v2 to see if there are any other comments. Thanks, Nik
