Hello! I've fixed this bug. MulticastGroupInterface (both ipv4 and ipv6) has link field for hash table, but has been inserted in two different tables: in MulticastFilter and sMulticastState. So when ~MulticastFilter was called, it was trying to free group interfaces from other tables.

The "Global" naming looks weird. Otherwise OK.

comment:5 by waddlesplash, 8 years ago

What else should it be called?

comment:6 by Carzil, 8 years ago

Hmm. fLinkForGlobalMulticastState should be better? Or too long?

comment:7 by korli, 8 years ago

Do fMulticastGroupsLink and MulticastGroupsHashLink() fit?

Replying to korli:

Do fMulticastGroupsLink and MulticastGroupsHashLink() fit?

Yes. That's good.
