[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.
