	  multicast_memberships status and the current values of the
	  ospf_interface state, type, and passive_interface status.

	  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

	a warning message and ignore the packet.

2005-01-10  Greg Troxel  <gdt@fnord.ir.bbn.com>

	* ospf_packet.h: Remove commented out definition of
	OSPF_MAX_PACKET; neither it or the uncommented one are used any more.

	* ospf_packet.c (ospf_make_ls_upd): Leave room for authentication
	when deciding if an update will fit.
	(ospf_packet_authspace): Factor out calculation of size required
	for authentication.
	(ospf_make_db_desc): Use ospf_max_packet, not OSPF_MAX_PACKET.

	* ospf_packet.c: (ospf_db_desc) Reduce severity of "Negotiation done"
	  messages from LOG_WARNING to LOG_INFO, since this seems to be
	  normal.

2004-12-29 Andrew J. Schorr <ajschorr@alumni.princeton.edu>

	* ospf_packet.c: (ospf_read) Always look up the interface if
	  ospf_recv_packet returns NULL ifp, since some platforms such
	  as Solaris 8 appear to support ifindex retrieval but don't.

2004-12-22 Hasso Tepper <hasso at quagga.net>

	* ospf_dump.c: Show debug configuration in vtysh.

	  message and in comment.
	  (ospf_db_desc) Warning message that a packet is being discarded
	  should give the router id of the packet source.  Fix spelling
	  of packet in two warning messages.
	  (ospf_ls_req) Warning message that a link state request is being
	  discarded should give the router id of the neighbor that sent it.

2004-11-26 Andrew J. Schorr <ajschorr@alumni.princeton.edu>

	* ospf_main.c: Remove #include "debug.h" (was not being used, and

2004-11-12 Paul Jakma <paul@dishone.st>

	* ospf_ia.c: (process_summary_lsa) Only an ABR has any reason to
          ignore stub area summary default. Even so it seems a strange
          check, add a comment to that effect.

2004-11-04 Paul Jakma <paul@dishone.st>

	* ospfd.c: (ospf_network_match_iface) revert to previous network
          statement match behaviour.

2004-11-02 Paul Jakma <paul@dishone.st>

	* ospf_packet.c: (ospf_write_frags) remove iov arg, msg already points
	  to it. Add convenience pointer to msg->msg_iov[1], and use this,
	  fixing the unfortunate borkenness introduced in moving of this code
	  to a function.
	  (ospf_write) remove iovp and fix up call to previous.
	  (ospf_ls_upd_packet_new) cast size to long int - unfortunately
          glibc's size_t format modifier is not portable.

2004-10-31 Paul Jakma <paul@dishone.st>

	* ospf_packet.c: (ospf_write_frags) Add debug output
	  (ospf_write) set type early, so we can pass it to

	  (ospf_ls_upd_packet_new) print size in debug output when too large
	  packet is encountered.
	* ospf_zebra.c: (ospf_distribute_list_update_timer) Ugly misuse of
	  THREAD_ARG to store an integer, but it should at least use same
          same type to retrieve the value. Assert value is sane.

2004-10-22 Paul Jakma <paul@dishone.st>

	* ospf_network.c: (ospf_sock_init) call neutral setsock_ifindex()
          function.
        * ospf_packet.c: (ospf_read) manually look up ifindex
          if system could not have returned one, eg openbsd, thanks to Rivo
	  Nurges for highlighting problem and fix.
          Change setsockopt_pktinfo to setsockopt_ifindex.

2004-10-19 Andrew J. Schorr <aschorr@telemetry-investments.com>

2004-10-11 Paul Jakma <paul@dishone.st>

	* ospf_dump.c: (ospf_ip_header_dump) Assume header is in host order
	  remove ntohs that should have dissappeared. Take struct ip
	  as argument, caller has to know there's an IP header at start of
	  stream anyway.
	* ospf_dump.h: update declaration of ospf_ip_header_dump.
	* ospf_packet.c: (ospf_write) correct call to
	  sockopt_iphdrincl_swab_htosys which was munging the header.
	  (ospf_recv_packet) ip_len is needed for old OpenBSD fixup.
	  (ospf_read) sockopt_iphdrincl_swab_systoh ip header as soon as
	  we have it.
	* (global) Const char update and signed/unsigned fixes.
	* (various headers) size defines should be unsigned.
	* ospf_interface.h: remove duplicated defines, include the
	  authoritative header - though, these defines should probably
          be moved to a dedicated header, or ospfd.h.
	* ospf_lsa.h: (struct lsa) ls_seqnum should be unsigned.
	* ospf_packet.c: (ospf_write) cast result of shift to unsigned.

2004-10-08 Hasso Tepper <hasso at quagga.net>

	* *.[c|h]: Fix compiler warnings: make some strings const, signed ->
	  unsigned, remove unused variables etc.

2004-10-07  Greg Troxel  <gdt@claude.ir.bbn.com>

	* ospf_apiserver.c (ospf_apiserver_unregister_opaque_type): Don't
	use of variable names 'node' and 'nextnode' to avoid possible
	conflict with list macros.  Move variable declaration inside for
	loop after a statement to top of function.

2004-10-07 Paul Jakma <paul@dishone.st>

	* ospf_snmp.c: Missed list typedef update
	* ospf_dump.c: Include sockopt.h for header swab functions.

2004-10-05 Paul Jakma <paul@dishone.st>

	* ospf_zebra.c: Read router id related messages from zebra daemon.
	  Schedule router-id update thread if it's changed.
	* ospfd.c: Remove own router-id selection function. Use router id from
	  zebra daemon if it isn't manually overriden in configuration.

2004-09-27 Paul Jakma <paul@dishone.st>

	* ospf_dump.c: (ospf_ip_header_dump) Use HAVE_IP_HDRINCL_BSD_ORDER
	  Apply to offset too. Print ip_cksum, lets not worry about
	  possible 2.0.37 compile problems.
	* ospf_packet.c: (ospf_swap_iph_to{n,h}) Use
	  HAVE_IP_HDRINCL_BSD_ORDER.
	  (ospf_recv_packet) ditto.
	  (ospf_write) Fixup iov argument to ospf_write_frags.
          (struct msghdr).msg_name is caddr_t on most platforms.
	  (ospf_recv_packet) ditto. And msg_flags is not always there
          memset struct then set fields we care about rather than
          initialise all fields individually.

2004-09-26 Hasso Tepper <hasso at quagga.net>

	* ospf_abr.c, ospf_dump.c, ospf_lsa.c, ospf_packet.c, ospf_vty.c,
	  ospf_zebra.c: Fix compiler warnings.

          referenced node in loop.
 	  (ospf_apiserver_term) loops calling ospf_apiserver_free, which

        * ospf_interface.h: lists typedef removal cleanup.
        * ospf_opaque.{c,h}: lists typedef removal cleanup. update some list
          loops to LIST_LOOP. miscellaneous style and indent fixups.

	  taking BSDisms into account.
	  (ospf_swab_iph_toh) the inverse.
	  (ospf_write) Add support for IP fragmentation, will only work on
	  linux though, other kernels make it impossible. get rid of the
	  magic 4 constant.
	  (ospf_make_ls_upd) Bound check to end of stream, not to
	  interface mtu.
	  (ospf_ls_upd_packet_new) New function, allocate upd packet
	  taking oversized LSAs into account.
	  (ospf_ls_upd_queue_send) use ospf_ls_upd_packet_new to allocate,
	  rather than statically allocating mtu sized packet buffer, which
	  actually was wrong - it didnt take ip header into account, which
	  should not be included in packet buffer.
	  (ospf_ls_upd_send_queue_event) minor tweaks and remove
	  TODO comment.

2004-08-31  David Wiggins  <dwiggins@bbn.com>

2004-08-27  Hasso Tepper  <hasso at quagga.net>

	* ospf_vty.c: Don't print ospf network type under interface only
	  if interface is in broadcast mode and interface type really is
	  broadcast. Fixes Bugzilla #108.

2004-08-27  David Wiggins  <dwiggins@bbn.com>

	* ospf_spf.c (ospf_nexthop_calculation): Initialize address family
	  in on-stack struct prefix_ipv4.  Fixes point-to-multipoint SPF
	  calculation.

2004-08-26  Greg Troxel  <gdt@fnord.ir.bbn.com>

	* ospf_packet.c (ospf_recv_packet): adjust size declaration of
	  buffer used to get interface index so that it compiles on other
	  than Linux and includes the required alignment space.  Probably
	  this was only working on sparc/sparc64 because most of
	  sockaddr_dl was not being written.

2004-08-19 Paul Jakma <paul@dishone.st>

	* ospf_packet.c: update to match sockopt renames.

2004-08-04 Paul Jakma <paul@dishone.st>

        * ospf_packet.c: (ospf_ls_upd_send_queue_event) fix thinko from
          last fix for ospfd wedging due to oversize LSAs: dont list loop on
          ospf_ls_upd_queue_send() - guaranteed segfault.

2004-07-27 Paul Jakma <paul@dishone.st>

	* ospf_opaque.c: (ospf_opaque_lsa_flush_schedule) do not NULL out
	  the LSA as then free_opaque_info_per_id() can never unlock (and
	  free) the LSA. Reported by Gunnar Stigen.

2004-07-23 Paul Jakma <paul@dishone.st>

	* ospf_network.c: Replace PKTINFO/RECVIF with call to
	  setsockopt_pktinfo

	* ospf_packet.c: (ospf_ls_upd_send_queue_event) Partial fix for
	  problem reported by Peter Frost amongst others, where function
	  will spin indefinitely if update list contains LSAs greater than

          (ospf_make_ls_upd) add comment about large LSA problem,
	  indentation cleanup.

2004-07-01  Greg Troxel  <gdt@fnord.ir.bbn.com>

	  IPTOS_PREC_INTERNETCONTROL otherwise.
	* ospf_packet.c:  (ospf_associate_packet_vl) cleanup, move
	  some of the checks up to ospf_read, return either a
	  virtual link oi, or NULL.
	  (ospf_read) Cleanup, make it responsible for checks. Remove
	  the nbr lookup - moved to ospf_neighbor. Adjust all nbr
	  lookups to use new wrappers exported by ospf_neighbor.
