[ospfd] Fix multicast membership drop bug
2006-06-15 Paul Jakma <paul.jakma@sun.com> * Reported by Milan Koci * ospf_interface.h: (struct ospf_if_info) Add reference counts for multicast group memberships. Add various macros to help manipulate/check membership state. * ospf_interface.c: (ospf_if_set_multicast) Maintain the ospf_if_info reference counts, and only actually drop memberships if it hits 0, to avoid losing membership when OSPF is disabled on an interface with multiple active OSPF interfaces. * ospf_packet.c: (ospf_{hello,read}) Use the new macros to check/set multicast membership. * ospf_vty.c: (show_ip_ospf_interface_sub) ditto.
