-
-	* ospf_network.c: (ospf_adjust_sndbuflen) Don't complain
-	  about getting more buffer space, than requested.
-	* ospfd.[ch]: (ospf_new) Abandon OSPF_SNDBUFLEN_DEFAULT
-	  and consider OS's initial buffer size instead.
-	* ospf_interface.c: (ospf_if_up) Fix missing argument.
-
-2007-08-21 Denis Ovsienko
-
-	* ospfd.h: Extend struct ospf with maxsndbuflen field and
-	  define its default value.
-	* ospfd.c: (ospf_new) init maxsndbuflen
-	* ospf_interface.c: (ospf_if_up) Call ospf_adjust_sndbuflen()
-	  for each regular interface being brought up.
-	* ospf_network.[ch]: (ospf_adjust_sndbuflen) New function
-	  makes sure ospf socket sending buffer is large enough
-	  to cover the biggest interface MTU we have seen ever.
-	* ospf_packet.c: (ospf_write) Use maxsndbuflen to decide on
-	  the biggest amount of data we are going to send at once.

-2007-08-07 Paul Jakma <paul.jakma@sun.com>
-
-	* ospf_spf.c: (ospf_spf_next) Finish off the explanatory
-	  comment made in previous commit
-
-2007-08-07 Atis Elsts <atis@mikrotik.com>
-
-	* ospf_spf.c: (ospf_spf_next) Sort heap in correct direction
-	  after vertex cost is changed, thus fixing incorrect SPF
-	  calculation on certain topologies.
-
-2007-08-06 Paul Jakma <paul.jakma@sun.com>
-
-	* ospf_lsa.c: (router_lsa_flags) Bug #331, NSSA regression caused
-	  caused ASBRs to not advertise E-bit into NSSA areas.
-
-2007-05-09 Milan Kocian <milon@wq.cz>
-
-	* ospf_vty.c: Fix commands: 'ip ospf authentication A.B.C.D',
-	  'no ip ospf authentication A.B.C.D', 'no ip ospf
-	  authentication-key A.B.C.D'. Simply fix argv's indexes and
-          argc check in DEFUN functions.
-
-2007-05-07 Paul Jakma <paul.jakma@sun.com>
-
-	* ospf_spf.c: (ospf_vertex_new) Dont init vertices to infinity,
-	  just let 0 be a special case.
-	  (ospf_spf_add_parent) 0 distance candidate vertex is special,
-	  cost still to be initialised - asserting that new distance
-	  is <= existing only makes sense where w already has a cost.
-	  (ospf_spf_next) Infinite cost links should not be followed,
-	  bar those of the root.
-
-2007-04-30 Andrew J. Schorr <ajschorr@alumni.princeton.edu>
-
-	* ospfd.c: (ospf_network_match_iface) Comment out
-	  COMPATIBILITY_MODE.  Going forward, the ospf "network" command
-	  will use a simple test: does the network command prefix
-	  contain the connected (destination) prefix of the interface?
-
-2007-04-21 Andrew J. Schorr <ajschorr@alumni.princeton.edu>
-
-	* ospf_interface.c: (ospf_if_set_multicast) Fix bug: was testing
-	  interface passive status improperly in light of the recent
-	  'passive-interface default' patch.  Now need to test
-	  OSPF_IF_PASSIVE_STATUS(oi) instead of
-	  OSPF_IF_PARAM(oi, passive_interface).
-
-2007-03-23 Paul Jakma <paul.jakma@sun.com>
-
-	* ospf_spf.c: (various) Add more debug statements.
-	  (ospf_nexthop_calculation) Fix silly regression causing ospfd
-	  to fail to calculate paths past networks not attached to root
-	  vertex, introduced with bug #330 fixes.
-
-2007-03-14 Andrew J. Schorr <ajschorr@alumni.princeton.edu>
-
-	* ospf_snmp.c: (ospf_snmp_neighbor_state) New function to
-	  map internal quagga neighbor states to SNMP standard values.
-	  (ospfNbrEntry) Call new ospf_snmp_neighbor_state function.
-
-2007-03-14 Andrew J. Schorr <ajschorr@alumni.princeton.edu>
-
-	* ospf_zebra.c: (ospf_zebra_add, ospf_zebra_delete) Fix bug
-	  where inet_ntoa was used twice in the same debug message,
-	  which doesn't work because there's a single shared buffer
-	  for the returned string.  The fix is to use inet_ntop.
-
-2007-02-27 Andrew J. Schorr <ajschorr@alumni.princeton.edu>
-
-	* ospfd.c: (ospf_terminate) Exit immediately if ospf is not
-	  actually running (e.g. the config file was empty).  Fixes
-	  bug where SIGTERM would not kill ospfd.
-
-2007-02-26 Paul Jakma <paul.jakma@sun.com>
-
-	* ospf_spf.c: Fix regression introduced with bug #330 fix: The
-	  cost update added to ospf_spf_add_parent only handled PtP
-	  case, differing from same functionality in higher-level
-	  ospf_spf_next. Regression diagnosed by Anders Pedersen,
-	  mailnews+router-quagga-dev@news.cohaesio.com.
-	  (ospf_vertex_new) Initialise vertices to max-cost.
-	  (ospf_spf_init) Root vertex always creates with 0 cost.
-	  (ospf_spf_add_parent) Remove the buggy V->W cost calculating
-	  code, instead take the new distance as a parameter.
-	  (ospf_nexthop_calculation) Take distance as parameter, so it
-	  can be passed down to add_parent.
-	  (ospf_spf_next) Dont initialise candiate vertex distance,
-	  vertex_new does so already. Pass distance down to
-	  nexthop_calculation (see above).
-
-2007-01-24 Paul Jakma <paul.jakma@sun.com>
-
-	* ospf_spf.c: Bug #330: Nexthop calculation sometimes may fail,
-	  and it needs to indicate this result to SPF.
-	  (ospf_spf_add_parent) Flush of parent list needs to be done here,
-	  for simplicity.
-	  (ospf_nexthop_calculation) Caller needs to know whether
-	  nexthop calculation succeeded. Every return statement must
-	  correctly indicate such.
-	  (ospf_spf_next) Queueing/prioritisation of vertices in SPF
-	  must take into account whether nexthop_calculation succeeded,
-	  or SPF may fail to find best paths.
-
-2006-12-12 Andrew J. Schorr <ajschorr@alumni.princeton.edu>
-
-	* ospf_interface.c: (ospf_if_is_configured, ospf_if_lookup_by_prefix,
-	  ospf_if_lookup_recv_if) Simplify logic using new CONNECTED_PREFIX
-	  macro.
-	* ospf_lsa.c: (lsa_link_ptop_set) Using the new CONNECTED_PREFIX
-	  macro, both options collapse into the same code.
-	* ospf_snmp.c: (ospf_snmp_if_update) Simplify logic using new
-	  CONNECTED_ID macro.
-	  (ospf_snmp_is_if_have_addr) Simplify logic using new CONNECTED_PREFIX
-	  macro.
-	* ospf_vty.c: (show_ip_ospf_interface_sub) Use new CONNECTED_PEER macro
-	  instead of testing the IFF_POINTOPOINT flag.
-	* ospfd.c: (ospf_network_match_iface) Use new CONNECTED_PEER macro
-	  instead of testing with if_is_pointopoint.  And add commented-out
-	  code to implement alternative (in my opinion) more elegant behavior
-	  that has no special-case treatment for PtP addresses.
-	  (ospf_network_run) Use new CONNECTED_ID macro to simplify logic.
-
-2006-12-04 Andrew J. Schorr <ajschorr@alumni.princeton.edu>
-
-	* ospfd.c: (ospf_network_run) Remove an offending 'break' statement.
-	  Previously, after creating a single ospf_interface on a given
-	  network interface, the code would skip to the next interface
-	  without considering other connected addresses on the interface.
-	  After removing the 'break', we now consider all connected addresses.
-
-2006-11-30 Andrew J. Schorr <ajschorr@alumni.princeton.edu>
-
-	* ospf_zebra.c: (ospf_router_id_update_zebra,
-	  ospf_interface_address_add, ospf_interface_address_delete)
-	  If (IS_DEBUG_OSPF (zebra, ZEBRA_INTERFACE)) is enabled, then
-	  add a debug message about what Zebra is telling us.
-	  (ospf_zebra_add_discard) Add a debug message matching the one
-	  already in ospf_zebra_delete_discard.
-
-2006-11-28 Andrew J. Schorr <ajschorr@alumni.princeton.edu>
-
-	* ospf_vty.c: (ospf_passive_interface_default) Take additional
-	  'newval' arg so we can update ospf->passive_interface_default inside
-	  this function.  More importantly, we now call ospf_if_set_multicast
-	  on all ospf_interfaces.
-	  (ospf_passive_interface, no_ospf_passive_interface) Fix bug:
-	  for 'default' case, argv[0] is undefined, so we must test for
-	  (argc == 0) before using argv[0].  And since
-	  ospf_passive_interface_default now calls ospf_if_set_multicast as
-	  needed, we can just return after calling
-	  ospf_passive_interface_default.
-
-2006-10-24 Andrew J. Schorr <ajschorr@alumni.princeton.edu>
-
-	* ospf_zebra.c: (ospf_redistribute_default_set) Fix bug where
-	  a new value for ospf->default_originate was being ignored
-	  if a previous 'default-information originate' command
-	  had already been processed.
-
-2006-10-22 Yar Tikhiy <yar@comp.chem.msu.su>
-
-	* (general) Add support for passive-interface default (with
-	  minor edits by Paul Jakma).
-	* ospf_interface.h: Add OSPF_IF_PASSIVE_STATUS macro, looking
-	  at configured value, or the global 'default' value, as
-	  required.
-	* ospf_interface.c: (ospf_if_new_hook) Leave passive
-	  unconfigured per default, allowing global 'default' to
-	  take effect for unconfigured interfaces.
-	* ospf_packet.c: (various) use OSPF_IF_PASSIVE_STATUS
-	* ospf_vty.c: (ospf_passive_interface_default) new function,
-	  unset passive from all interfaces if default is enabled, as
-	  the per-iface settings become redundant.
-	  (ospf_passive_interface_update) new func, update passive
-	  setting taking global default into account.
-	  ({no,}ospf_passive_interface_addr_cmd) Add support for
-	  'default' variant of command.
-	  (show_ip_ospf_interface_sub) Update to take global
-	  default into account when printing passive status.
-	  (ospf_config_write) ditto.
-	* ospfd.c: (ospf_new) set global passive-interface default.
-	* ospfd.h: (struct ospf) Add field for global
-          passive-interface.
-

-	  Fix zlog_warn messages to eliminate compiler warnings.
-	  (ospf_hello) Improve warning messages to show why we
-	  are complaining.
-
-2006-08-28 Andy Gay <andy@andynet.net>
-
-	* ospf_packet.c: (ospf_make_db_desc) Assert added with More-bit
-	  fixes does not hold up with addition of Ogier DB-Exchange
-	  optimisation, which can empty the db-summary list in between
-	  sent DD packets. Remove assert, update More-bit always when
-	  in Exchange.
-
-2006-08-27 J.J. Krabbendam <jkrabbendam@aimsys.nl>
-
-	* ospfd.c: (ospf_finish_final) default redistribute should be
-	  unset too, fixes bug where reconfiguring ospfd completely
-	  can no longer enable default redistribution.
-
-2006-08-25 Paul Jakma <paul.jakma@sun.com>
-
-	* (general) Bug #134. Be more robust to backward time changes,
-	  use the newly added libzebra time functions.
-	  In most cases: recent_time -> recent_relative_time()
-	  gettimeofday -> quagga_gettime (QUAGGA_CLK_MONOTONIC, ..)
-	  time -> quagga_time.
-	  (ospf_make_md5_digest) time() call deliberately not changed.
-	  (ospf_external_lsa_refresh) remove useless gettimeofday, LSA
-	  tv_orig time was already set in ospf_lsa_new, called via
-	  ospf_external_lsa_new.
-
-2006-08-04 Paul Jakma <paul.jakma@sun.com>
-
-	* ospf_lsdb.c: (ospf_lsdb_delete_entry) new function, consolidate

-	  (ospf_lsdb_delete_all) ditto.
-
-2006-08-03 Paul Jakma <paul.jakma@sun.com>
-
-	* ospf_packet.c: (ospf_make_db_desc) Unset the DD More bit
-	  after constructing the packet, if appropriate. 
-	  (ospf_db_desc_proc) Speed up Exchange, slave should raise
-	  ExchangeDone earlier, as RFC mandates, by forming its reply
-	  before deciding whether both sides are done, avoids a
-	  needless round of empty DD packet exchanges at the end of
-	  Exchange, hence speeding up ExchangeDone.
-	  Implement draft-ogier-ospf-dbex-opt DB-exchange optimisation.
-	  (ospf_db_desc) use UNSET_FLAG macro.
-
-2006-07-27 Andrew J. Schorr <ajschorr@alumni.princeton.edu>
-
-	* ospfd.c: (ospf_router_id_update) Fix and document the algorithm for
-	  selecting the router ID: if there is not a statically configured ID,
-	  then stick to the most recent value to avoid disruptive changes.
-	  This should fix bug #288.
-
-2006-07-26 Paul Jakma <paul.jakma@sun.com>
-
-	* ospf_lsa.{c,h}: (ospf_lsa_unlock) Change to take a double pointer
-	  to the LSA to be 'unlocked', so that, if the LSA is freed, the
-	  callers pointer to the LSA can be NULLed out, allowing any further
-	  use of that pointer to provoke a crash sooner rather than later.
-	* ospf_*.c: (general) Adjust callers of ospf_lsa_unlock to match
-	  previous. Try annotate 'locking' somewhat to show which 'locks'
-	  are protecting what LSA reference, if not obvious.
-	* ospf_opaque.c: (ospf_opaque_lsa_install) Trivial: remove useless
-	  goto, replace with return.
-	* ospf_packet.c: (ospf_make_ls_ack) Trivial: merge two list loops,
-	  the dual-loop predated the delete-safe list-loop macro.
-
-2006-07-25 Paul Jakma <paul.jakma@sun.com>
-
-	* ospf_neigbor.h: (struct ospf_neighbor) Add some additional
-	  neighbour state statistics fields, timestamps for progressive
-	  and regressive state changes, and pointer to event string
-	  for the latter state change.
-	* ospf_nsm.c: (nsm_notice_state_change) Update new state changs
-	  history as required.
-	* ospf_vty.c: (show_ip_ospf_neighbor_detail_sub) Print out above
-	  new per-neighbour state change stats.
-
-2006-07-10 Paul Jakma <paul.jakma@sun.com>
-
-	* ospf_nsm.c: (nsm_change_state) call nsm_clear_adj for all
-	  adjacency losses, hence removing need for nsm_reset_nbr.
-	  (nsm_reset_nbr) kill it, clear_adj in previous does fine.
-	  (nsm_kill_nbr,nsm_start) remove nsm_reset_nbr call.
-	  (ospf_nsm_event) Allow NSM function to be NULL, this along with
-	  removal of nsm_reset_nbr, allows a bunch of now useless functiosn
-	  to be removed.
-	  Remove some useless variables.
-	  (nsm_ignore) now useless, remove.
-	  (nsm_bad_ls_req) ditto
-	  (nsm_seq_number_mismatch)   "
-	  (nsm_oneway_received)       "
-	  (nsm_inactivity_timer)      "
-	  (nsm_ll_down)               "
-	  (NSM) replace removed action functions with NULL.
-	  (nsm_notice_state_changes) Move state change logging code to new
-	  func to declutter nsm_change_state and ospf_nsm_event.
-	  Log event with AdjChange, it's useful to know.
-	  (nsm_change_state) move adjchange and snmp logging to previous.
-	  (ospf_nsm_event) call nsm_notice_state_changes from here.
-	  Move the debug message to entry of function, so it gets out
-	  even if something goes wrong.
-	  Record state change timestamp and event in nbr struct.
-	* ospf_neighbor.h: (struct ospf_neighbor) Add fields to record
-	  timestamp of last NSM change and event.
-	* ospf_vty.c: (show_ip_ospf_neighbor_detail_sub) Print 
-	  last state change timestamp and event, if available.
-
-2006-07-10 Andrew J. Schorr <ajschorr@alumni.princeton.edu>
-
-	* ospf_packet.c: (ospf_hello) Improve NetworkMask mismatch warning
-	  message to include interface name and conflicting prefix lengths.
-
-2006-07-07 Paul Jakma <paul.jakma@sun.com>
-
-	* ospf_nsm.h: Add a NSM_Deleted neighbour state, to act as dummy
-	  state indicating the neighbour is to be deleted.
-	* ospf_nsm.c: (general) Use the NSM_Deleted state to delete
-	  neighbours, thus allowing code to be slightly more obvious
-	  in its flow.
-	  (nsm_timer_set) Add NSM_Deleted. Add another timer the code
-	  missed.
-	  (nsm_kill_nbr) No need for special case call to nsm_change_state
-	  anymore.
-	  Make the assert and error-handling for same case more readable
-	  (Andrew Schorr)
-	  Remove the call to ospf_nbr_delete, nsm_change_state can do
-	  this generally now via NSM_Deleted.
-	  (struct ... NSM) Add the dummy NSM_Deleted state, the 3 events
-	  that can lead to nsm_kill_nbr all now transition the NBR to
-	  NSM_Deleted and the general change_state function can be left
-	  to do the work.
-	  (ospf_nsm_event) Special casing of events and early-return can
-	  be removed now.
-	  On transition into Deleted, delete the nbr.
-	* ospf_dump.c: (ospf_nsm_state_msg) Add Deleted.
-
-2006-07-06 Paul Jakma <paul.jakma@sun.com>
-
-	* ospf_nsm.c: (ospf_nsm_event) LLDown event also results in nbr
-	  being deleted, requires early-return too. Likely explains
-	  some crash reports after interface events.
-
-2006-07-04 Paul Jakma <paul.jakma@sun.com>
-
-	* ospf_nsm.c: (general) Various small cleanups from Andrew's
-	  review of last set of patches.
-	  (nsm_timer_set) Loading, Full and default can share
-	  same code too.
-	  (nsm_should_adj) Can just be one big OR.
-	  (nsm_twoway_received) Collapse into return statement.
-
-2006-07-02 Paul Jakma <paul.jakma@sun.com>
-
-	* ospf_nsm.c: (nsm_should_adj) New function, just consolidate the
-	  10.4 adjacency check from nsm_twoway_received/nsm_adj_ok.
-	  (nsm_twoway_received/nsm_adj_ok) Use former.
-	  (nsm_clear_adj) clear adjacency related state for a
-	  neighbour, needed for some state changes from > ExStart down
-	  to ExStart or less, which need not go through nsm_reset_nbr.
-	  (nsm_reset_nbr) move code to former. Should be static.
-	  (ospf_nsm_event) Don't allow action functions to change
-	  next_state if the NSM tables do not indicate next_state is
-	  conditional, log warning if one tries - existing code
-	  appears fine though.
-	  Remove long dead code.
-	  Use nsm_clear_adj for state changes that take down
-	  adjacencies to TwoWay/ExStart.
-	  (nsm_timer_set) ls_req timer should be OFF in early states.
-	  Compact several identical sections.
-	  Set inactivity timer to OFF for Down, for documentary
-	  purposes.
-	  (nsm_kill_nbr) Oops, action function shouldn't try return
-	  1 for error.
-	* ospf_lsa.c: (ospf_translated_nssa_refresh) CID #13.
-
-2006-06-30 Andrew J. Schorr <ajschorr@alumni.princeton.edu>
-
-	* ospf_vty.c: (show_ip_ospf_neighbor_id) Should show all instances
-	  of that neighbor (since it may appear on multiple interfaces)
-	  instead of bailing out after showing the first match.
-
-2006-06-29 Andrew J. Schorr <ajschorr@alumni.princeton.edu>
-
-	* ospf_nsm.c: (nsm_twoway_received) When deciding whether to
-	  change from state Init to ExStart, the test for whether the
-	  neighboring router is DR or BDR should be against the
-	  local router's notion of DR/BDR, not the neighbor's view.
-
-2006-06-28 Erik Muller <erikm@internap.com>
-
-	* ospfd.h: Define 2 new struct ospf config flags:
-	  OSPF_LOG_ADJACENCY_CHANGES and OSPF_LOG_ADJACENCY_DETAIL
-	* ospf_nsm.c (nsm_change_state): Log adjacency changes if
-	  requested.
-	* ospf_vty.c (ospf_log_adjacency_changes): New command function
-	  to implement ospf subcommand "log-adjacency-changes [detail]".

-	  no_ospf_log_adjacency_changes.
-
-2006-06-26 Paul Jakma <paul.jakma@sun.com>
-
-	* ospf_abr.c: (general) NSSA translate-candidate ABRs need to
-	  be ASBRs, or other routers may rightfully refuse to install
-	  translated type-5s LSAs. reported by dendroot@gmail.com.
-	  (ospf_abr_nssa_check_status) Detect change in translator
-	  state when ABR, and inc/dec redistribute count as when we
-	  leave/enter the disabled state - so that translate-enabled
-	  ABR properly sets ASBR bit on non-NSSA areas.
-	  Run the resulting function through indent to clean it up.
-	* ospf_lsa.c: (router_lsa_flags) For purposes of ASBR bit,
-	  NSSA area is same as stub area.
-	  
-2006-06-24 Andrew J. Schorr <ajschorr@alumni.princeton.edu>
-
-	* ospf_snmp.c: (ospfTrapNbrStateChange, ospfTrapIfStateChange) Improve
-	  info log message to indicate why the trap is being sent.
-
-2006-06-24 Andrew J. Schorr <ajschorr@alumni.princeton.edu>
-
-	* ospf_dump.c: (config_write_debug) Fix typo to show debug ospf nsm
-	  status properly (not ism status).
-
-2006-06-17 Andrew J. Schorr <ajschorr@alumni.princeton.edu>
-
-	* ospf_vty.c: ({no_,}ospf_passive_interface) Replace if_lookup_by_name
-	  with a call to if_get_by_name -- if the interface does not exist
-	  already, it should be created.  And remove the obsolete warning
-	  message.
-
-2006-06-15 Paul Jakma <paul.jakma@sun.com>
-
-	* 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.
-	  
-2006-05-31 Paul Jakma <paul.jakma@sun.com>

-2006-05-13 Paul Jakma <paul.jakma@sun.com>
-
-	* ospf_lsa.c: (ospf_translated_nssa_refresh) fix the sanity
-	  check to match the assert, small error in CID #13 fix.
-
-2006-05-12 Paul Jakma <paul.jakma@sun.com>
-
-	* ospf_lsa.c: (ospf_lsa_action) Get rid of the ospf_lookup
-	  call, which is not checked for NULL return, by stripping out
-	  functionality which is never used, hence fixing Coverity CID
-	  #29.
-	  (struct lsa_action) remove unused member.
-	  (ospf_translated_nssa_refresh) Add non-assert sanity check,
-	  in case DEBUG isn't defined.
-	  Debug message when no type7 exists should print the ID from
-	  the type5, not the type7, fixes CID #13.
- 	* ospf_interface.c: (ospf_if_exists) Fix missing NULL return
-	  check on ospf_lookup, CID #27.
-	* ospf_asbr.c: (ospf_redistribute_withdraw) remove ospf_lookup
-	  call by taking the struct ospf * as argument, which the
-	  caller has, fixing CID #28.
-	* ospf_asbr.h: (ospf_redistribute_withdraw) update declaration
-	* ospf_zebra.c: (ospf_redistribute_unset) update call to
-	  ospf_redistribute_withdraw to match.
-	* ospf_ia.c: (ospf_update_router_route) ospf->backbone could be
-	  NULL when passed to ospf_find_asbr_route_through_area,
-	  check for NULL first, CID #14.
-	* ospf_ism.c: (ism_change_state) NULL check on oi->area is
-	  useless, it's always valid. Only possibility where it
- 	  couldn't be is if there is a race between abr_task and
-	  cleaning up oi's, in which case a NULL check here isn't going
-	  to do anything. Fixes CID #15.
-
-2006-05-11 Paul Jakma <paul.jakma@sun.com>

-	* ospf_route.c: (ospf_route_delete_same_ext) Fix deref before
-	  NULL check by moving into check-protected block, fix CID #49.
-	* ospf_abr.c: (ospf_area_range_cost_set) Shouldn't create a new
-	  range, should just lookup to see if one exists, the new range
-	  is just leaked. Fixes CID #46.
-	* ospf_lsa.c: (ospf_default_originate_timer) Let the thread
-	  take (struct ospf *) as thread argument, rather than (struct
-	  ospf *)->default_originate, thus avoiding having to call
-	  ospf_lookup.
-	* ospf_zebra.c: (ospf_redistribute_default_set) change setup
-	  of ospf_default_originate_timer thread to match.
-	* ospfd.c: (ospf_router_id_update) ditto.

-	  backbone, don't bother checking.
-	* ospf_spf.c: (static struct list vertex_list) Record vertices
-	  that will need to be freed.
-	  (cmp) Order network before router vertices, as required,
-	  wasn't implemented.
-	  (vertex_nexthop_free) Mild additional robustness check.
-	  (vertex_parent_free) Take void argument, as this function
-	  is passed as list deconstructor for vertex parent list.
-	  (ospf_vertex_new) More debug. Set deconstructor for parent
-	  list. Track allocated vertices on the vertex_list.
-	  (ospf_vertex_free) Get rid of the tricky recursive cleanup of

-	  vertex_list nodes and letting ospf_vertex_free as deconstructor
-	  work per-node.
-	  (ospf_spf_calculate_timer) Trivial optimisation, leave
-	  backbone SPF calculation till last to reduce SPF churn on
-	  VLink updates.
-	* ospf_vty.c: (ospf_find_vl_data) update call to ospf_vl_lookup
-	  (no_ospf_area_vlink_cmd) ditto.

-	  pinpoint the issue.
-	* ospf_interface.c: (ospf_vl_new) Add nbr_self for Vlink.
-	* ospf_neighbor.c: (ospf_nbr_key) new static function, helper
-	  to create key in nbrs table for a given nbr.

-2006-03-25 Paul Jakma <paul.jakma@sun.com>
-
-	* ospf_interface.c: (ospf_if_lookup_recv_if) Ignore loopbacks,
-	  we can never ever receive packets on those. Should fix
-	  case where CARP is run with address in same subnet as real
-	  interface. Problem report and diagnosis thanks to:
-	  Landon Fuller <landonf@opendarwin.org>.
-	  However, ospf_read() still can't deal deterministically with
-	  multiple interfaces in same subnet.
-
-2006-03-23 Steve Lawson <steve.lawson@aheadcomusa.com>
-
-	* ospf_lsa.c: (ospf_lsa_install) Fix incorrect byte-order

-           Remove stray semi-colons which cause empty-statement
-           warnings.
-
-2006-01-18 Juergen Kammer <j.kammer@eurodata.de>
-
-	* ospf_lsa.c: (ospf_router_lsa_new) dont take reference to the

-
-	* ospfd.c: (ospf_new) stub-shutdown should just default to
-	  unconfigured, too strange otherwise.
-	  (ospf_finish_final) t_opaque_lsa_self TIMER_OFF should be
-	  preprocessor conditional on HAVE_OPAQUE_LSA.
-	* ospfd.h: (struct ospf) remove the SHUTDOWN_DEFAULT define.

-
-	* ospf_{dump,spf,vty}.c: Oops, use the internal tv_sub

-	* ospf_dump.h: export ospf_timeval_dump.
-	* ospf_flood.c: (ospf_flood) remove gettimeofday, use
-	  the libzebra exported recent_time instead, as it's not
-	  terribly critical to have time exactly right - the dropped
-	  LSA will be retransmited to us if we don't ACK it.
-	* ospf_packet.c: (ospf_ls_upd_timer) Ditto, but here we're
-	  not transmitting, just putting LSA back on update transmit list.

-	  now, update with gettimeofday.
-	  (ospf_spf_calculate_schedule) Change SPF timers to millisecond
-	  resolution.
-	  Make the holdtime be adaptive, with a linear increase in
-	  holdtime ever consecutive SPF run which occurs within holdtime
-	  of previous SPF, bounded by spf_max_holdtime.
-	* ospf_vty.c: Update spf timers commands.
-	  (ospf_timers_spf_set) trivial helper. 
-	  (ospf_timers_throttle_spf_cmd) new command to set SPF delay,
-	  initial hold and max hold times with millisecond resolution.

-
-	* (general) OSPF fast, sub-second hello and 1s dead-interval
-	  support.
-	* ospf_dump.c: (ospf_timer_dump) Print out milliseconds too.

-	  millisecs unless they specify the additional length.
-	* ospf_interface.h: (struct ospf_interface) new interface param, 
-	  fast_hello.
-	* ospf_interface.c: (ospf_if_table_lookup) add brackets,
-	  gcc warning fix.

-	  (OSPF_HELLO_TIMER_ON) new macro to set hello timer according

-	  former is used when hello is to be sent immediately.
-	* ospf_nsm.c: ditto
-	* ospf_packet.c: (ospf_hello) hello-interval is not checked
-	  for mismatch if fast_hello is set.
-	  (ospf_read) Annoying nit, fix "no ospf_interface" to be debug
-	  rather than a warning, as it can be perfectly normal to
-	  receive packets when logical subnets are used.
-	  (ospf_make_hello) Set hello-interval to 0 if fast-hellos are
-	  configured.
-	* ospf_vty.c: (ospf_auto_cost_reference_bandwidth) annoying
-	  nit, don't vty_out if this command is given, it gets tired
-	  quick.
-	  (show_ip_ospf_interface_sub) Print the hello-interval 
-	  according to whether fast-hello is set or not.
-	  Print the extra 5 millisec characters from (ospf_timer_dump)
-	  if fast-hello is configured.
-	  (ospf_vty_dead_interval_set) new function, common to all
-	  forms of dead-interval command, to set dead-interval and
-	  fast-hello correctly. If a dead-interval is given, unset
-	  fast-hello, else if a hello-multiplier is set, set
-          dead-interval to 1 and fast-hello to given multiplier.
-	  (ip_ospf_dead_interval_addr_cmd) use
-	  ospf_vty_dead_interval_set().

-	  (no_ip_ospf_dead_interval) Unset fast-hello.
-	  (no_ip_ospf_hello_interval) Bug-fix, unset of hello-interval
-	  should set it to OSPF_HELLO_INTERVAL_DEFAULT, not
-	  OSPF_ROUTER_DEAD_INTERVAL_DEFAULT.
-	  (config_write_interface) Write out fast-hello.
-	  (ospf_config_write) Write a comment about 
-	  "auto-cost reference-bandwidth" having to be equal on all
-	  routers. Hopefully just as noticeable as old practice of
-	  writing to vty, but less annoying.
-	  (ospf_vty_if_init) install the two new dead-interval
-	  commands.
-	* ospfd.h: Add defines for OSPF_ROUTER_DEAD_INTERVAL_MINIMAL
-	  and OSPF_FAST_HELLO_DEFAULT.

-2005-10-18 Paul Jakma <paul.jakma@sun.com>
-
-	* (general) SPF memory management cleanup and fix for rare
-	  double-free bug.
-	* ospf_spf.h: (struct vertex_parent) New struct to hold parent
-	  specific data, eg the backlink and the parent vertex pointer,
-	  and point to the appropriate general struct vertex_nexthop.
-	  (struct vertex_nexthop) remove parent vertex pointer, so
-	  this struct can be shared across vertices.
-	  (struct vertex) rename list child to list children. Remove
-	  list of nexthops, replace with list of vertex_parents.
-	* ospf_spf.c: (update_stat) trivial, remove cast from void *.
-	  (vertex_nexthop_new) remove init of parent - field is gone
-          from struct vertex_nexthop.
-          (ospf_canonical_nexthops_free) Remove the canonical
-          vertex_nexthop memory objects. These are the vertex_nexthops
-          attached to the first level of router vertices from the root.
-          (vertex_parent_new) new function, create a vertex_parent.
-          (vertex_parent_free) ditto, but free it.
-          (ospf_vertex_new) Update to match changes to struct vertex.
-          (ospf_vertex_free) Recursively free a struct vertex and its
-          children. The parent list is used as a reference count.
-          vertex_nexthops must be free seperately, if required.
-          (ospf_vertex_dump) update to match struct vertex changes.
-          Print out backlink of parents too.
-          (ospf_vertex_add_parent) ditto.
-          (ospf_lsa_has_link) update comment.
-          (ospf_nexthop_add_unique) removed, not needed anymore.
-          (ospf_nexthop_merge) ditto.
-          (ospf_spf_consider_nexthop) renamed to ospf_spf_add_parent.
-          Simplified to just create vertex_parent and add it.
-          (ospf_spf_flush_parents) new function, flush out the parent
-	  list.
-	  (ospf_nexthop_calculation) Take the relevant route_lsa_link
-	  as an argument, which simplifies things and removes the need
-	  for the hack in ospf_nexthop_add_unique - ospf_spf_next
-	  already knew exactly which link the cost calculated was for.
-	  Update to match struct vertex changes too.
-	  (ospf_spf_next) Don't create a vertex for W unnecessarily, if
-          it's there's a vertex already created for W, use it, and
-          hence there's no need to free it either.
-          Update some manipulation/comparisons of distance to match.
-          Flush the parent list if a lower cost path is found.
-          (ospf_spf_route_free) unused, removed.
-          (ospf_spf_dump) match the struct vertex changes, and dump the
-          ifname if possible.
-          (ospf_spf_calculate) At end of SPF, free the canonical nexthops
-          and call ospf_vertex_free on the root vertex to free the
-	  entire tree.
-	* ospf_interface.c: (ospf_vl_set_params) match struct vertex
-          changes.
-        * ospf_route.c: (ospf_intra_route_add) ditto
-          (ospf_route_copy_nexthops_from_vertex) ditto
-

-
-	* ospf_dump.c: Remove local hard-coded table ospf_redistributed_proto.
-	  (ospf_redist_string) New function implemented using new library
-	  function zebra_route_string().  Note that there are a few differences
-	  in the output that will result: the new function returns strings
-	  that are lower-case, whereas the old table was mixed case.  Also,
-	  the old table mapped ZEBRA_ROUTE_OSPF6 to "OSPFv3", whereas the
-	  new function returns "ospf6".
-	* ospfd.h: Remove extern struct message ospf_redistributed_proto[],
-	  and add extern const char *ospf_redist_string(u_int route_type)
-	  instead.
-	* ospf_asbr.c: (ospf_external_info_add) In two messages, use
-	  ospf_redist_string instead of LOOKUP(ospf_redistributed_proto).
-	* ospf_vty.c: Remove local hard-coded table distribute_str.
-	  (config_write_ospf_redistribute,config_write_ospf_distribute): Use
-	  new library function zebra_route_string() instead of distribute_str[].
-	* ospf_zebra.c: (ospf_redistribute_set,ospf_redistribute_unset,
-	  ospf_redistribute_default_set,ospf_redistribute_check)
-	  In debug messages, use ospf_redist_string() instead of
-	  LOOKUP(ospf_redistributed_proto).

-2005-07-26 Paul Jakma <paul.jakma@sun.com>
-
-	* ospf_abr.c: (ospf_abr_announce_network_to_area) SET_FLAG

-	  had been fixed long ago by Sowmini.
-
-2005-05-19 Paul Jakma <paul.jakma@sun.com>
-
-	* ospf_interface.c: (ospf_if_table_lookup) Fix a serious bug
-	  a less serious one. 
-	  1: this function is supposed to lookup
-	  entries in the oifs ospf_interface route_table and return either
-	  an existing oi or NULL to indicate not found, its caller depends
-	  on this, yet this function uses route_node_get which /always/
-	  returns a route_node - one is created if none exists. Use
-	  route_node_lookup instead. This should fix root cause of the
-	  reports of the (ospf_add_to_if) assert being hit.
-	  2: oi's are inserted into this table with prefixlength set to
-	  /32 (indeed, it should be a hash table, not a route_table),
-	  however prefixlength to lookup was not changed, if no valid entry
-	  can be inserted other than /32, then nothng but /32 should be
-	  looked up. This possibly only worked by fluke..
-	  Fix confirmed by 2 reporters (one list, one IRC), definitely a
-	  backport candidate once it has been incubated in HEAD for a while.
-	  Thanks to Patrick Friedel and Ivan Warren for testing.
-

-	* ospf_lsa.c: (ospf_discard_from_db) dont call
-	  ospf_ase_unregister_external_lsa for opaque-lsa's, opaques are
-	  never registered with ase in the first place.

-          tendency to try gather up things into temporary lists.
-          (ospf_ls_upd) remove the temporary lists opaque uses, call
-          opaque functions inline, just like all other types.
-          (ospf_ls_ack) ditto.
-          (ospf_recv_packet) fixup sign warning.
-        * ospf_opaque.c: (general) fix the unneeded use of lists, and
-          untwist some of the logic.
-          (ospf_opaque_self_originated_lsa_received) take a single LSA
-          as argument, not a list of them. Remove the list loop. Logic 
-          otherwise unchanged.
-          (ospf_opaque_ls_ack_received) Mostly ditto. But untwist the logic,
-          move the actions up into the switch block, remove the goto's and
-          sanitise the logic near the end a bit.
-        * ospf_opaque.h: Adjust definitions of aforementioned functions
-          in ospf_opaque.c to match.
-         
-2005-05-07 Yar Tikhiy <yar@comp.chem.msu.su>

-	  events.
-
-2005-05-06 Paul Jakma <paul.jakma@sun.com>
-
-        * (general) extern and static qualifiers added. 
-          unspecified arguments in definitions fixed, typically they should
-          be 'void'.
-          function casts added for callbacks.
-          Guards added to headers which lacked them.
-          Proper headers included rather than relying on incomplete
-          definitions.
-          gcc noreturn function attribute where appropriate.
-        * ospf_opaque.c: remove the private definition of ospf_lsa's 
-          ospf_lsa_refresh_delay.
-        * ospf_lsa.h: export ospf_lsa_refresh_delay
-        * ospf_packet.c: (ospf_make_md5_digest) make *auth_key const, 
-          correct thing to do - removes need for the casts later.
-        * ospf_vty.c: Use vty.h's VTY_GET_INTEGER rather than ospf_vty's
-          home-brewed versions, shuts up several warnings.
-        * ospf_vty.h: remove VTY_GET_UINT32. VTY_GET_IPV4_ADDRESS and
-          VTY_GET_IPV4_PREFIX moved to lib/vty.h.
-        * ospf_zebra.c: (ospf_distribute_list_update_timer) hacky
-          overloading of the THREAD_ARG pointer should at least use
-          uintptr_t.
-
-2005-04-15 Zhipeng Gong <zpgong@cdc.3upsystems.com>
-
-	* ospf_abr.c: (ospf_abr_announce_network_to_area) dont forget

-	  interface changes, print a debug message and call ospf_if_reset()
-	  to simulate down/up on the interface.
-	* ospf_interface.h: Declare new function ospf_if_reset().
-	* ospf_interface.c: (ospf_if_reset) New function to call ospf_if_down
-	  and ospf_if_up for all ospf interfaces attached to an interface.
-
-2005-03-29 Andrew J. Schorr <ajschorr@alumni.princeton.edu>
-
-	* ospf_packet.c: (ospf_write_frags) Enhance error message to
-	  show MTU.  Also make function static.
-	  (ospf_write) Enhance error message to show interface name and MTU.
-	  Also make function static.
-
-2005-03-29 Andrew J. Schorr <ajschorr@alumni.princeton.edu>
-
-	* 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

-2005-03-25 Hasso Tepper <hasso at quagga.net>
-
-	* ospfd.h: Include log.h, fixes compile with gcc-4.0.
-
-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
-	  the modulus.
-
-2005-02-23 Andrew J. Schorr <ajschorr@alumni.princeton.edu>
-
-	* ospfd.h: Add new field struct stream *ibuf to struct ospf.
-	* ospfd.c: (ospf_new) Check return code from ospf_sock_init.
-	  Allocate ibuf using stream_new(OSPF_MAX_PACKET_SIZE+1).
-	  (ospf_finish) Call stream_free(ospf->ibuf.
-	* ospf_packet.c: (ospf_read) Call stream_reset(ospf->ibuf) and then
-	  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>

-	  ospf_install_candidate() and ospf_spf_register() functions not needed
-	  any more. Update ospf_vertex_new(), ospf_spf_next() and

-
-	* ospf_packet.c: (ospf_read) Always look up the interface if

-	  (ospf_ls_upd_send_queue_event) minor tweaks and remove
-	  TODO comment.
-	  
-2004-08-31  David Wiggins  <dwiggins@bbn.com>
