	* 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>
	* 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. | 
|  | 2006-05-31 Paul Jakma <paul.jakma@sun.com>
	* ospf_lsdb.c: (ospf_lsdb_delete) robustify against NULL arguments,
	  print warning.
	* ospf_lsa.c: (ospf_discard_from_db) ditto.
	  (ospf_maxage_lsa_remover) Check lsa->lsdb for validity, possible
	  mitigation (but not solution) for bug #269. | 
|  | 2006-05-30 Paul Jakma <paul.jakma@sun.com>
	* ospf_packet.c: (ospf_read) Debug message about packets
	  received on unenabled interfaces should be conditional on
	  debug being set. | 
|  | 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_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. | 
|  | 2006-05-12 Paul Jakma <paul.jakma@sun.com>
	* 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. | 
|  | 2006-05-12 Paul Jakma <paul.jakma@sun.com>
	* 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. | 
|  | 2006-05-12 Paul Jakma <paul.jakma@sun.com>
	* 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. | 
|  | 2006-05-12 Paul Jakma <paul.jakma@sun.com>
	* ospf_interface.c: (ospf_if_exists) Fix missing NULL return
	  check on ospf_lookup, CID #27. | 
|  | 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. | 
|  | 2006-05-11 Paul Jakma <paul.jakma@sun.com>
	* 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. | 
|  | 2006-05-11 Paul Jakma <paul.jakma@sun.com>
	* 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. | 
|  | 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. | 
|  | 2006-05-11 Paul Jakma <paul.jakma@sun.com>
	* ospf_vty.c: (no_ospf_area_filter_list) Check NULL result from
	  ospf_area_lookup_by_area_id, fixes Coverity CID #69 | 
|  | 2006-05-11 Paul Jakma <paul.jakma@sun.com>
	* ospf_vty.c: (general) Audit ospf_lookup calls in commands,
	  ensure check for NULL result, make vty messages consistent.
	  (show_ip_ospf_interface) Missing NULL check on ospf_lookup
	  result, fixes Coverity CID #70. | 
|  | 2006-04-24 Paul Jakma <paul.jakma@sun.com>
	* (general) More Virtual-link fixes, again with much help in
	  testing / debug from Juergen Kammer. Primarily in SPF.
	* ospf_spf.h: Add guard. ospf_interface.h will include this
	  header.
	* ospf_interface.h: Modify ospf_vl_lookup definition to take
	  struct ospf as argument, so as to allow for NULL area
	  argument.
	  (struct ospf_vl_data) Remove out_oi, instead add a struct
	  vertex_nexthop, to use as initial nexthop for backbone paths
	  through a vlink.
	* ospf_interface.c: (ospf_vl_lookup) Modified to allow
	  NULL area to be passed to indicate "any" (first) area.
	  Add extra debug.
	  (ospf_vl_set_params) vl_oi -> nexthop. Add extra debug.
	  (ospf_vl_up_check) Fix debug, inet_ntoa returns a static
	  buffer..
	* ospf_route.c: (ospf_intra_add_router) Vlinks dont go through
	  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
	  vertices. Now frees only the given vertex.
	  (ospf_vertex_add_parent) Fix assert.
	  (ospf_nexthop_calculation) Fix calculation of nexthop for
	  VLink vertices, lookup the vl_data and use its previously
	  recorded nexthop information.
	  (ospf_spf_calculate) Vertices are freed simply by deleting
	  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.
	  (show_ip_ospf_interface_sub) For Vlinks, the peer address is
	  more interesting than the output interface. | 
|  | 2006-04-03 Paul Jakma <paul.jakma@sun.com>
	* (general) Fix issues with handling of Vlinks and entries
	  in the nbrs route-table which were highlighted by the
	  nsm/nbr_self fixes from bug #234. Many thanks to Juergen
	  Kammer for his help and efforts in testing out debug patches to
	  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.
	  (ospf_nbr_delete) Use ospf_nbr_key. Add an assert() to
	  document an expected state.
	  (ospf_nbr_add_self) Ditto.
	  (ospf_nbr_lookup_by_addr) Add an assert.
	* ospf_nsm.c: (nsm_kill_nbr) Can never kill the nbr_self

	* ospf_lsa.c: (ospf_lsa_checksum) Add an explicit cast to avoid
	  the ambiguities of ANSI and C99 C with respect to type
	  conversion. Detailed problem report and test case with
	  example data supplied by Dmitry Ivanov <dimss@telecentrs.lv>. | 
|  | 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
	  conversion of OSPF_MAX_SEQUENCE_NUMBER | 
|  | 2006-01-19 Paul Jakma <paul.jakma@sun.com>
        * (general) various miscellaneous compiler warning fixes.
          Remove redundant break statements from switch clauses
          which return.
          return from main, not exit, cause it annoys SOS.
          Remove stray semi-colons which cause empty-statement
          warnings.
	* zebra/main.c: (sighup) remove private declaration of external
	  function. | 
|  | 2006-01-18 Juergen Kammer <j.kammer@eurodata.de>

|  | 2006-01-10 Len Sorensen <lennartsorensen@ruggedcom.com>
	* (general) Bug #234, see also [quagga-dev 3902].
	  Fix problem with nbr_self not being properly reinitialised
	  when an interface comes up, after having been down.
	  Some re-arrangement done by Paul Jakma, any bugs introduced
	  on top of Len's suggested changes are his.
	* ospf_neighbor.c: (ospf_nbr_add_self) centralise
	  initialisation of nbr_self parameters here.
	* ospf_interface.c: (ospf_if_new) deleting initialisation of

	  redundant strings. | 
|  | 2006-01-10 Paul Jakma <paul.jakma@sun.com>
	* ospfd.c: (ospf_network_run) checking to see if router-id
	  is set should be on ospf->router_id, not router_id_static.
	  This was causing ospfd to not start if router-id had not
	  been configured statically.
	  (ospf_if_update) ditto. | 
|  | 2005-11-26 Paul Jakma <paul.jakma@sun.com>
	* (general) s/graceful/deferred/ in all files, the former term
	   is confusing wrt OSPF Graceful-Restart.
	* ospfd.c: (ospf_deferred_shutdown_check) dont return
	  a function which returns void. SOS complains about this.
	  (ospf_finish) |

          (ospf_summary_lsa_new) Check ID is valid.
          (ospf_summary_lsa_originate) ditto, and check returned LSA from
           previous function is !NULL.
          (ospf_summary_lsa_refresh) check ospf_summary_lsa_new return
           is !NULL.

          (ospf_network_run) router-id update timer gone.
          call ospf_router_id_update directly if ID not configured.
          In the per-iface loop, don't ospf_if_up interfaces if
          ID is still not configured. The update function will call
          ospf_if_update anyway.
          (ospf_if_update) ID update timer is gone. Just return if no
          ID is set.
        * ospf_vty.c: (ospf_router_id) call ospf_router_id_update, no
          timer needed.
        * ospf_zebra.c: (ospf_router_id_update_zebra) call

	* ospf_ism.h: (OSPF_ISM_TIMER_OFF) Improve macro syntax by enclosing
	  in 'do {...} while(0)'. | 
|  | 2005-11-14 Paul Jakma <paul.jakma@sun.com>

	  (struct ospf)
	  Add stub_router_{startup,shutdown_}time, configuration of startup
	  and shutdown time for stub-router.
	  Add t_graceful_shutdown struct thread, timer for graceful
	  shutdown, if needed.
	  (struct ospf_area) Add stub_router_state - run time state of

|  | * (general) SPF millisecond resolution timer with adaptive,
	  linear back-off holdtime. Prettification of ospf_timer_dump.
	* ospf_dump.c: (ospf_timeval_dump) new function. The guts of

	  (ospf_timer_dump) guts moved to ospf_timeval_dump.
	* 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.

	  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.
	  (ospf_timers_spf_cmd) Deprecated. Accept the old values,
	  convert to msec, truncate to new limits.
	  (no_ospf_timers_throttle_spf_cmd) set timers to defaults.

	  (ospf_vty_init) install the new SPF throttle timer commands. | 
|  | * (general) OSPF fast, sub-second hello and 1s dead-interval
	  support. A warning fix. Millisec support for ospf_timer_dump.
	  Change auto-cost ref-bandwidth to add a comment to write out
	  of config, rather than printing annoying messages to vty on
	  startup.
	* ospf_dump.c: (ospf_timer_dump) Print out milliseconds too.
	  Callers typically specify a length of 9, so most see
	  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_new_if_params) Initialise fast_hello param.
	  (ospf_free_if_params) Check whether fast_hello is configured.
	  (ospf_if_new_hook) set fast_hello to default.
	* ospf_ism.h: Wrap OSPF_ISM_TIMER_ON inside do {} while (0) to
	  prevent funny side-effects from its if statement when this
	  macro is used conditionally by other macros.
	  (OSPF_ISM_TIMER_MSEC_ON) new macro, set in milliseconds.
	  (OSPF_HELLO_TIMER_ON) new macro to set hello timer according
	  to whether fast_hello is set.
	* ospf_ism.c: Update all setting of the hello timer to use
	  either OSPF_ISM_TIMER_MSEC_ON or OSPF_HELLO_TIMER_ON. The
	  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().
	  (ip_ospf_dead_interval_minimal_addr_cmd) ditto.
	  (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. | 
|  | * (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
	* memtypes.c: (memory_list_ospf) Add MTYPE_OSPF_VERTEX_PARENT. | 
|  | * ospf_api.c: sign warnings.
	* ospf_apiserver.c: sign warning and convert all the struct
	  in_addr initialisations so as not to make assumptions about
	  how this struct is organised, initialise the s_addr member
	  explicitely.
	* ospf_packet.c: Add const qualifier to auth_key. | 
|  | * ospf_snmp.c: Avoid mixing interface and ospf_interface objects
          which now allows snmpwalk to work with ospfIfTable and
          also with ospfIfMetricTable | 
|  | * zebra.h: Declare new functions zebra_route_string() and
	  zebra_route_char().
	* log.c: (zroute_lookup,zebra_route_string,zebra_route_char) New
	  functions to map zebra route numbers to strings.
	* zebra_vty.c: (route_type_str) Remove obsolete function: use new
	  library function zebra_route_string() instead.  Note that there
	  are a few differences: for IPv6 routes, we now get "ripng" and
	  "ospf6" instead of the old behavior ("rip" and "ospf").
	  (route_type_char) Remove obsolete function: ues new library function
	  zebra_route_char() instead.  Note that there is one difference:
	  the old function returned 'S' for a ZEBRA_ROUTE_SYSTEM route,
	  whereas the new one returns 'X'.
	  (vty_show_ip_route_detail,vty_show_ipv6_route_detail) Replace
	  route_type_str() with zebra_route_string().
	  (vty_show_ip_route,vty_show_ipv6_route) Replace route_type_char()
	  with zebra_route_char().
	* bgp_vty.c: (bgp_config_write_redistribute) Use new library function
	  zebra_route_string instead of a local hard-coded table.
	* ospf6_asbr.c: Remove local hard-coded tables zroute_name and
	  zroute_abname. Change the ZROUTE_NAME macro to use new library
	  function zebra_route_string().  Remove the ZROUTE_ABNAME macro.
	  (ospf6_asbr_external_route_show): Replace ZROUTE_ABNAME() with
	  a call to zebra_route_char(), and be sure to fix the format string,
	  since we now have a char instead of a char *.
	* ospf6_zebra.c: Remove local hard-coded tables zebra_route_name and
	  zebra_route_abname.  Note that the zebra_route_name[] table
	  contained mixed-case strings, whereas the zebra_route_string()
	  function returns lower-case strings.
	  (ospf6_zebra_read_ipv6): Change debug message to use new library
	  function zebra_route_string() instead of zebra_route_name[].
	  (show_zebra): Use new library function zebra_route_string() instead
	  of zebra_route_name[].
	* 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).
	* rip_zebra.c: (config_write_rip_redistribute): Remove local hard-coded
	  table str[]. Replace str[] with calls to new library function
	  zebra_route_string().
	* ripd.c: Remove local hard-coded table route_info[].
	  (show_ip_rip) Replace uses of str[] with calls to new library
	  functions zebra_route_char and zebra_route_string.
	* ripng_zebra.c: (ripng_redistribute_write) Remove local hard-coded
	  table str[].  Replace str[i] with new library function
	  zebra_route_string(i).
	* ripngd.c: Remove local hard-coded table route_info[].
	  (show_ipv6_ripng) Use new library function zebra_route_char() instead
	  of table route_info[]. |
