* ospf_interface.h: Improve passive_interface comment. Add new multicast_memberships bitmask to struct ospf_interface to track active multicast subscriptions. Declare new function ospf_if_set_multicast. * ospf_interface.c: (ospf_if_set_multicast) New function to configure multicast memberships properly based on the current multicast_memberships status and the current values of the ospf_interface state, type, and passive_interface status. (ospf_if_up) Remove call to ospf_if_add_allspfrouters (this is now handled by ism_change_state's call to ospf_if_set_multicast). (ospf_if_down) Remove call to ospf_if_drop_allspfrouters (now handled by ism_change_state). * ospf_ism.c: (ospf_dr_election) Remove logic to join or leave the DRouters multicast group (now handled by ism_change_state's call to ospf_if_set_multicast). (ism_change_state) Add call to ospf_if_set_multicast to change multicast memberships as necessary to reflect the new interface state. * ospf_packet.c: (ospf_hello) When a Hello packet is received on a passive interface: 1. Increase the severity of the error message from LOG_INFO to LOG_WARNING; 2. Add more information to the error message (packet destination address and interface address); and 3. If the packet was sent to ospf-all-routers, then try to fix the multicast group memberships. (ospf_read) When a packet is received on an interface whose state is ISM_Down, enhance the warning message to show the packet destination address, and try to update/fix the multicast group memberships if the packet was sent to a multicast address. When a packet is received for ospf-designated-routers, but the current interface state is not DR or BDR, then increase the severity level of the error message from LOG_INFO to LOG_WARNING, and try to fix the multicast group memberships. * ospf_vty.c: (ospf_passive_interface) Call ospf_if_set_multicast for any ospf interface that may have changed from active to passive. (no_ospf_passive_interface) Call ospf_if_set_multicast for any ospf interface that may have changed from passive to active. (show_ip_ospf_interface_sub) Show multicast group memberships.
