I believe (without reproducing it) that the problem was igmp_v3_cancel_link_timers() not cancelling the v3 link timer in all situations. The panic you saw was due to a v3 timer firing even though the timer should have been cancelled by reception of the v2 query from your university's LAN router. The RFC could be worded better about how the 'Older Querier' timer is heeded -- on re-reading it makes sense not to flap between IGMP versions -- the oldest version in use on the link persists for up to 260s with the default protocol timers, only switching version after the timer expires is best as it provides some built-in hysteresis. It sounds like the fix is OK. Obviously, let me know if you see problems again, I've checked the patch into HEAD now. thanks, BMSReceived on Mon Jun 01 2009 - 13:50:01 UTC
