	* ospf_vty.c: (show_ip_ospf_interface_sub) Display interface MTU and
	  bandwidth; this is useful for debugging problems.  Also, the function
	  should be static.

2005-03-27 Hasso Tepper <hasso at quagga.net>

	* ospf_snmp.c: Don't crash in snmp query if ospf instance doesn't
	  exist at all.

2005-03-25 Hasso Tepper <hasso at quagga.net>

2005-03-13 Andrew J. Schorr <ajschorr@alumni.princeton.edu>

	* ospf_lsa.c: (ospf_lsa_refresh_walker) If the system clock jumps
	  backward, then current time may be less than
	  ospf->lsa_refresher_started.  This was causing invalid values
	  for ospf->lsa_refresh_queue.index resulting in infinite loops.
	  Problem fixed by casting the expression to unsigned before taking

	  pass it to ospf_recv_packet for use in receiving the packet
	  (instead of allocating a new stream for each packet received).
	  Eliminate all calls to stream_free(ibuf).
	  (ospf_recv_packet) The struct stream *ibuf is now passed in as
	  an argument.  No need to use recvfrom to peek at the packet
	  header (to see how big it is), just use ospf->ibuf which is
	  always large enough (this eliminates a system call to recvfrom).
	  Therefore, no need to allocate a stream just for this packet,
	  and no need to free it when done.

2005-02-23 Vincenzo Eramo <eramo at infocom.ing.uniroma1.it>

	  to make sure we continue to get incoming messages.

2005-02-15 Paul Jakma <paul.jakma@sun.com>

	  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

	  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_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.

	* ospf_vty.c: Bugfix to show really number of AS external LSAs, not
	  number of all LSAs with AS scope, this includes opaque as LSAs as
	  well, show this number separately. Show numbers and sums of
	  checksums for each type of LSAs.

	  to a function.
	  (ospf_write) remove iovp and fix up call to previous.
	  (ospf_ls_upd_packet_new) cast size to long int - unfortunately

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

	  packet is encountered.
	* ospf_zebra.c: (ospf_distribute_list_update_timer) Ugly misuse of

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

	* ospf_network.c: (ospf_sock_init) call neutral setsock_ifindex()
          function.

	  stream anyway.
	* ospf_dump.h: update declaration of ospf_ip_header_dump.
	* ospf_packet.c: (ospf_write) correct call to

	  (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.

	  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_packet.c: Fix bugzilla #107
 	  (ospf_packet_max) get rid of the magic 88 constant
	  (ospf_swab_iph_ton) new function. set ip header to network order,
	  taking BSDisms into account.  
	  (ospf_swab_iph_toh) the inverse.

	  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,

	  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
