bgpd/ChangeLog

2007-04-22 Sebastien Tandel <sebastien@tandel.be>

	* bgp_advertise.c : (baa_hash_alloc, baa_hash_key, baa_hash_cmp)
	  conforms to quagga hash API. Defines _hash_[alloc|key|cmp] with
	  void * arguments as defined by the API.
	* bgp_aspath.c,h : (aspath_key_make) conforms to quagga hash API.
	  Defines _hash_[alloc|key|cmp] with void * arguments as defined by
	  the API.
	* bgp_attr.c,h : (cluster_hash_alloc, cluster_hash_key_make,
	  cluster_hash_cmp, transit_hash_alloc, transit_hash_key_make,
	  transit_hash_cmp, attrhash_key_make, attrhash_cmp,
	  bgp_attr_hash_alloc) conforms to quagga hash API. Defines
	  _hash_[alloc|key|cmp] with void * arguments as defined by the API.
	* bgp_attr.h : Definition of BGP_ATTR_DEFAULT_WEIGHT.
	* bgp_attr.c : (bgp_attr_default_intern) now uses 
	  bgp_attr_default_set instead of duplicating the same code.
	  (general) Use of BGP_ATTR_DEFAULT_WEIGHT. Replace two 16 by
	  IPV6_MAX_BYTELEN.

2007-04-15 Sebastien Tandel <sebastien@tandel.be>

	* bgp_aspath.c: (aspath_as_add, aspath_segment_add) Minor performance
	  optimization: while loop should test one pointer instead of two.

2007-04-08 Paul Jakma <paul.jakma@sun.com>

	* bgp_route.c: (general) Same bug as fixed on 2006-11-28 by ajs for
	  bgp static routes, but for main BGP RIB: Quick 'flap' of routes
	  can cause bgpd to mistake a new route for a duplicate route,
	  due to presence of removed, but not yet processed BGP RIB entry.
	  (bgp_update_rsclient) Ignore REMOVED bgp_info for duplicate,
	  restore route instead.
	  (bgp_update_main) Ditto.
	* bgp_attr.c: (general) Bug #354: parsing of MP_REACH_NLRI and
	  MP_UNREACH_NLRI does not take sufficient care to ensure reads
	  from stream buffer stay in-bounds. Hence bgpd may attempt to read
	  beyond end of stream, if given a crafted packet. As it uses the
	  stream access methods to do so, this will typically result in
	  assert() being hit in stream.c. Where code is compiled without
	  assert() enabled, result is unknown.
	  (struct message attr_str) should be static.
	  (bgp_mp_reach_parse) Carefully check length remaining in stream
	  against amount desired to read from stream, prior to each read,
	  particularly where lengths are conditional on data obtained from
	  stream - using STREAM_READABLE.
	  Remove code to parse SNPA-number, it's a defunct field and changed
	  to a fixed size in latest BGP MP update RFC - log warning if
	  SNPA-number is not 0.
	  (bgp_mp_unreach_parse) Check withdraw_length carefully against
	  STREAM_READABLE.
	  (bgp_attr_parse) If attribute-parser function returns error, log
	  warning.
	  Log attribute type on mismatch.

2007-04-07 Paul Jakma <paul.jakma@sun.com>

	* bgpd.c: (general) Fix bug #352
	  (bgp_config_write_family_header) write ipv6/multicast
	  address family header.
	  (bgp_config_write) write out ipv6 multicast AF config.

2007-02-22 Paul Jakma <paul.jakma@sun.com>

	* bgp_fsm.c: (bgp_fsm_change_status) Handle state change into
	  clearing or greater here. Simpler.
	  (bgp_event) Clearing state change work moved to previous
	* bgp_route.c: (bgp_clear_route_node) Clearing adj-in here
	  is too late, as it leaves a race between a peer being deleted
	  and an identical peer being configured before clearing
	  completes, leading to a crash.
	  Simplest fix is to clean peers Adj-in up-front, rather than
	  queueing such work.
	  (bgp_clear_route_table) Clear peer's Adj-In and Adj-Out
	  up-front here, rather than queueing such work.
	  Extensive comment added on the various bits of indexed data
	  that exist and how they need to be dealt with.
	  (bgp_clear_route) Update comment.

2006-12-12 Andrew J. Schorr <ajschorr@alumni.princeton.edu>
	
	* bgp_nexthop.c: (bgp_connected_add, bgp_connected_delete)
	  Simplify logic by using new CONNECTED_PREFIX macro.

2006-12-07 Paul Jakma <paul.jakma@sun.com>

	* bgp_fsm.c: Bug #302 fix, diagnosis, suggestions and testing
	  by Juergen Kammer <j.kammer@eurodata.de>. Fix follows from
	  his suggested fix, just made in a slightly different way.
	  (bgp_event) Transitions into Clearing always must call
	  bgp_clear_route_all().
	  (bgp_stop) No need to clear routes here, BGP FSM should do
	  it.
 
2006-11-30 Andrew J. Schorr <ajschorr@alumni.princeton.edu>

	* bgp_debug.h: Declare new bgp_debug_zebra conf and term flags,
	  and define BGP_DEBUG_ZEBRA.
	* bgp_debug.c: Declare conf_bgp_debug_zebra and term_bgp_debug_zebra.
	  (debug_bgp_zebra, no_debug_bgp_zebra, undebug_bgp_zebra) New
	  functions to enable/disable bgp zebra debugging.
	  (no_debug_bgp_all) Turn off zebra debugging.
	  (show_debugging_bgp) Show whether zebra debugging is on.
	  (bgp_config_write_debug) Add 'debug bgp zebra' if configured.
	  (bgp_debug_init) Add new zebra debugging commands.
	* bgp_zebra.c: (bgp_router_id_update, bgp_interface_add,
	  bgp_interface_delete, bgp_interface_up, bgp_interface_down,
	  bgp_interface_address_add, bgp_interface_address_delete,
	  zebra_read_ipv4, zebra_read_ipv6, bgp_zebra_announce,
	  bgp_zebra_withdraw, bgp_redistribute_set, bgp_redistribute_unset)
	  If zebra debugging is enabled, log an appropriate debug message.

2006-11-28 Andrew J. Schorr <ajschorr@alumni.princeton.edu>

	* bgp_route.c: (bgp_info_restore) New function that undoes
	  the effects of a previous call to bgp_info_delete.  This is
	  used when a route is deleted and quickly re-added before the
	  deletion has been processed.
	  (bgp_static_update_rsclient, bgp_static_update_main,
	  bgp_redistribute_add) Check whether a pre-existing route
	  has the BGP_INFO_REMOVED set, and, if so, we need to call
	  bgp_info_restore to resurrect it.

2006-10-27 Paul Jakma <paul.jakma@sun.com>

	* bgp_route.c: (bgp_table_stats) oops, u_intXX_t should be
	  uintXX_t

2006-10-19 Paul Jakma <paul.jakma@sun.com>

	* bgpd.c: (peer_new) bgp element of peer absolutely must be
	  filled in, make peer_new() require it as argument and update
	  all callers. Fixes a crash reported by Jan 'yanek' Bortl and
	  Andrew Schorr where bgpd would crash in bgp_pcount_adjust
	  trying to dereference the bgp member of bgp->peer_self,
	  triggered through redistribution.
	* bgp_route.c: (bgp_pcount_adjust) assert sanity of arguments.

2006-10-15 Paul Jakma <paul.jakma@sun.com>

	* bgp_route.c: (bgp_table_stats_walker) NULL deref if table is
	  empty, bgp_table_top may return NULL, Coverity CID#73.
	* bgp_packet.c: (bgp_update_packet) adv->rn can not be NULL,
	  check is bogus - changed to assert(), CID#64.
	  binfo is checked for NULL, but then dereferenced
	  unconditionally, fix, CID #63.
	  (bgp_withdraw_packet) Assert adv->rn is valid, as with
	  bgp_update_packet().

2006-10-14 Paul Jakma <paul.jakma@sun.com>

	* bgp_fsm.h: Remove BGP_EVENT_FLUSH_ADD, dangerous and not
	  needed.
	* bgp_fsm.c: (bgp_stop) Move BGP_EVENT_FLUSH to the top of the
	  of the function, otherwise it could flush a ClearingCompleted
          event, bug #302.
	* bgp_packet.c: Replace all BGP_EVENT_FLUSH_ADD with
	  BGP_EVENT_ADD, fixing bug #302.

2006-09-19 Andrew J. Schorr <ajschorr@alumni.princeton.edu>

	* bgpd.c: (peer_uptime) Fix printf format/arg mismatch in
	  zlog_warn message (%ld/size_t -> %lu/u_long).

2006-09-14 Paul Jakma <paul.jakma@sun.com>

	* bgp_route.c: (bgp_table_stats_walker) Address space announced
	  should only count top-level unaggregateable prefixes, to
	  avoid falling afoul of anti-dodgy-accounting regulations
	  in various jurisdictions.. ;)
	  (bgp_process_queue_init) process queue hold time too high,
	  adds extra memory load. Change to be much lower, until such
	  time as it's made configurable.

2006-09-14 Paul Jakma <paul.jakma@sun.com>

	* (general) fix the peer refcount issue exposed by previous, by
	  just removing refcounting of peer threads, which is mostly
	  senseless as they're references leading from struct peer,
	  which peer_free cancels anyway. No need to muck around..
	* bgp_fsm.h: Just remove the refcounting from the various
	  TIMER/READ/WRITE/EVENT ON/OFF/ADD macros.
	* bgp_fsm.c: (bgp_stop) use BGP_EVENT_FLUSH, no refcounts attached
	  to events anymore.
	  (bgp_event) remove peer_unlock, events not refcounted.
	* bgpd.c: (peer_free) flush events before free.

2006-09-14 Paul Jakma <paul.jakma@sun.com>

	* (general) Fix some niggly issues around 'shutdown' and clearing
	  by adding a Clearing FSM wait-state and a hidden 'Deleted'
	  FSM state, to allow deleted peers to 'cool off' and hit 0
	  references. This introduces a slow memory leak of struct peer,
	  however that's more a testament to the fragility of the
	  reference counting than a bug in this patch, cleanup of
	  reference counting to fix this is to follow.
	* bgpd.h: Add Clearing, Deleted states and Clearing_Completed
	  and event.
	* bgp_debug.c: (bgp_status_msg[]) Add strings for Clearing and
	  Deleted.
	* bgp_fsm.h: Don't allow timer/event threads to set anything
	  for Deleted peers.
	* bgp_fsm.c: (bgp_timer_set) Add Clearing and Deleted. Deleted
	  needs to stop everything.
	  (bgp_stop) Remove explicit fsm_change_status call, the
	  general framework handles the transition.
	  (bgp_start) Log a warning if a start is attempted on a peer
	  that should stay down, trying to start a peer.
	  (struct .. FSM) Add Clearing_Completed
	  events, has little influence except when in state
	  Clearing to signal wait-state can end.
	  Add Clearing and Deleted states, former is a wait-state,
	  latter is a placeholder state to allow peers to disappear
	  quietly once refcounts settle.
	  (bgp_event) Try reduce verbosity of FSM state-change debug, 
	  changes to same state are not interesting (Established->Established)
	  Allow NULL action functions in FSM.
	* bgp_packet.c: (bgp_write) Use FSM events, rather than trying
	  to twiddle directly with FSM state behind the back of FSM.
	  (bgp_write_notify) ditto.
	  (bgp_read) Remove the vague ACCEPT_PEER peer_unlock, or else
	  this patch crashes, now it leaks instead.
	* bgp_route.c: (bgp_clear_node_complete) Clearing_Completed
	  event, to end clearing.
	  (bgp_clear_route) See extensive comments.
	* bgpd.c: (peer_free) should only be called while in Deleted,
	  peer refcounting controls when peer_free is called.
	  bgp_sync_delete should be here, not in peer_delete.
	  (peer_delete) Initiate delete. 
	  Transition to Deleted state manually.
	  When removing peer from indices that provide visibility of it,
	  take great care to be idempotent wrt the reference counting
	  of struct peer through those indices.
	  Use bgp_timer_set, rather than replicating.
	  Call to bgp_sync_delete isn't appropriate here, sync can be
	  referenced while shutting down and finishing deletion.
	  (peer_group_bind) Take care to be idempotent wrt list references
	  indexing peers.

2006-09-13 Paul Jakma <paul.jakma@sun.com>

	* bgp_aspath.c: (aspath_highest) new, return highest ASN in an
	  aspath.
	* bgp_route.c: (bgp_peer_count_walker) new, do the walk done
	  in bgp_peer_counts as a thread.
	  (bgp_peer_counts) move walk to previous and call it via
	  thread_execute so this RIB walk shows up in thread stats.
	  (bgp_table_stats) New, gather some statistics for a given
	  RIB.
	  (bgp_table_stats_walker) New, RIB walker thread for former.
	  (bgp_table_stats_vty) Parsing front-end for 'show bgp ...',
	  useful model for future rationalisation of 'show ... bgp'.
	  (bgp_route_init) Add new RIB stats commands.
	
2006-09-06 Paul Jakma <paul.jakma@sun.com>

	* (general) Squash any and all prefix-count issues by
	  abstracting route flag changes, and maintaining count as and
	  when flags are modified (rather than relying on explicit
	  modifications of count being sprinkled in just the right
	  places throughout the code).
	* bgp_route.c: (bgp_pcount_{dec,inc}rement) removed.
	  (bgp_pcount_adjust) new, update prefix count as
	  needed for a given route.
	  (bgp_info_{uns,s}et_flag) set/unset a BGP_INFO route status
	  flag, calling previous function when appropriate.
	  (general) Update all set/unsets of flags to use previous.
	  Remove pcount_{dec,inc}rement calls.
	  No need to unset BGP_INFO_VALID in places where
	  bgp_info_delete is called, it does that anyway.
	* bgp_{damp,nexthop}.c: Update to use bgp_info_{un,}set_flag.
	* bgp_route.h: Export bgp_info_{un,}set_flag.
	  Add a 'meta' BGP_INFO flag, BGP_INFO_UNUSEABLE.
	  Move BGP_INFO_HOLDDOWN macro to here from bgpd.h

2006-09-03 Paul Jakma <paul.jakma@sun.com>

	* bgp_route.c: Add 'show ... bgp ... <neighbour> prefix-count'
	  commands, to provide detailed counts of prefixes for a peer.
	  Informative, and should help pin down to pfxcnt drift
	  problems.

2006-08-27 Paul Jakma <paul.jakma@sun.com>

	* bgp_advertise.c: (bgp_sync_delete) fix mtype in XFREE.
	  NULL out peer->hash after free, to be sure.

2006-08-06 Paul Jakma <paul.jakma@sun.com>

	* bgp_aspath.c: (aspath_loop_check) Fix the typo-bug which
	  essentially had disabled this check. Problem reported by
	  Bartek Kania <mrbk@gnarf.org> in [quagga-users 7388].

2006-07-27 Paul Jakma <paul.jakma@sun.com>

	* bgpd.c: (peer_delete) Ensure freed buffers can not be
	  accidently reused. A potential fix for bug #287.

2006-07-02 Paul Jakma <paul.jakma@sun.com>

	* bgp_fsm.c: (bgp_{stop,start}) Move clear/free of certain
	  bits of state from stop to start, as they may be used via
	  peer references on clearing queues..

2006-05-23 Paul Jakma <paul.jakma@sun.com>

	* bgp_vty.c: (neighbor_update_source_cmd) Expand tab completion
	  to make it clear it takes both address and ifname.

2006-05-12 Paul Jakma <paul.jakma@sun.com>

	* bgp_attr.c: (bgp_packet_attribute) Remove dead code, Coverity
	  CID #1
	* bgp_aspath.{c,h}: (aspath_print_vty) take a format string,
	  so as to reduce burden on callers, all in bgp_route.c
	* bgp_route.c: (bgp_static_update_main) Remove useless NULL
	  check, code already assumes bgp_static can not be NULL, 
	  fixes CID #7.
	  (bgp_static_update_rsclient) ditto, CID #6
	  (route_vty_out{,tmp}) Update to match aspath_print_vty,
	  simplifying checks needed to get spacing right. CID #4,#5.
	  ({damp,flap}_route_vty_out) Ditto, CID #9, #10

2006-05-08 Paul Jakma <paul.jakma@sun.com>

	* bgp_community.c: (community_str2com) Coverity CID#62, fix
	  double-free, use-after-free.
	* bgp_route.c: (bgp_afi_node_get) given table should never be
	  NULL, check/assert this.
	  (bgp_static_update) Bug #240. Rsclients should only be passed
	  the static update if they are configured for the afi,safi.

2006-05-04 Paul Jakma <paul.jakma@sun.com>

	* (general) VPNv4 fixes. Certain VPNv4 code was not enabled.
	  See bug #210.
	* bgp_attr.{c,h}: (bgp_packet_{withdraw,attribute}) Tag should be
	  u_char really.
	* bgp_packet.c: (bgp_{update,withdraw}_packet) Enable some
	  VPNv4 code which inexplicably was ifdef'd out. comments from
	  a tester on IRC suggest this fixes bug #210.
	* bgp_route.c: (general) Fix logical bug in clearing, noted
	  by Chris Caputo in [quagga-users 6728] - clearing depended on
	  at least one route being added to workqueue, in order for
	  workqueue completion function to restart FSM. However, if no
	  routes are cleared, then the completion function never is
	  called, it needs to be called manually if the workqueue
	  didn't get scheduled. 
	  Finally, clearing is per-peer-session, not per AFI/SAFI, so
	  the FSM synchronisation should be in bgp_clear_route_table.
	  (bgp_clear_route_table) Wrong place for FSM/clearing
	  synchronisation, move to..
	  (bgp_clear_route) FSM/clearing synchronisation should be
	  here.
	  If no routes were cleared, no workqueue scheduled, call
	  the completion func to ensure FSM kicks off again.

2006-03-30 Paul Jakma <paul.jakma@sun.com>

	* bgp_community.c: (community_gettoken) Unknown token should
	  return NULL, to give a strong indication to callers that
	  the token no longer can be parsed, otherwise callers looping
	  on this function may have a hard time ending their loop.
	  (community_str2com) While loop around community_gettoken appears
	  to have been coded thinking that break statement would break
	  from the while{}, hence it could never exit for unknown token
	  case. Fix it to do..while, so it can use the NULL result from
	  community_gettoken easily.

2006-03-22 Paul Jakma <paul.jakma@sun.com>

	* bgpd.c: (peer_free) release the per-peer workqueue when
	  freeing the peer.

2006-03-19 Paul Jakma <paul.jakma@sun.com>

	* bgpd/bgp_vty.c: Add includes to get several structs we want
	  to provide usage statistics on.
	  (show_bgp_memory_cmd) Show memory usage stats for various
	  notable fixed size objects. Using mtype_stats_alloc and
	  mtype_memstr recently added to memory.c.
	  (bgp_show_summary) Report some additional stats specific to
	  the given BGP instance and/or AFI/SAFI such as table counts,
	  peers, rsclients and peer-groups.
	  (bgp_vty_init) Install show_bgp_memory_cmd.
	* bgp_nexthop.h: Include if.h as a dependent header, for struct
	  connected.
	* bgp_advertise.c: Use a distinct memory type for struct
	  bgp_synchronize.

2006-03-12 Paul Jakma <paul.jakma@sun.com>

	* bgp_attr.h: (struct attr) rearrange fields to avoid
	  wasted padding between them as much as possible.
	  (attr_count,attr_unknown_count) export new functions to
	  return number of counts of cached attributes.
	* bgp_attr.c: (attr_count,attr_unknown_count) new functions to
	  return number of counts of cached attributes.
	* bgp_route.h: (struct bgp_info) rearrange fields to avoid
	  wasted padding.
	* bgp_table.h: (struct bgp_table) Add a count field, of number
	  of nodes in the table.
	  (struct bgp_node)  rearrange fields to avoid
	  wasted padding between them, though I don't think there
	  was any in this case. 
	* bgp_table.c: (bgp_node_{delete,get}) Maintain the table node count.
	  (bgp_table_count) new function to access the table count.

2006-03-03 Paul Jakma <paul.jakma@sun.com>

	* bgp_route.c: (bgp_clear_node_complete) Doh. When clearing
	  is complete we need to kick off FSM again.

2006-02-21 Paul Jakma <paul.jakma@sun.com>

	* bgpd.h: move the clear_node_queue to be peer specific.
	  Add a new peer status flag, PEER_STATUS_CLEARING.
	* bgp_table.h: (struct bgp_table) Add fields to record afi,
          safi of the table.
          (bgp_table_init) Take afi and safi to create table for.
        * bgp_table.c: (bgp_table_init) record the afi and safi.
        * bgp_nexthop.c: Update all calls to bgp_table_init.
        * bgp_vty.c: ditto.
        * bgpd.c: ditto.
        * bgp_fsm.c: (bgp_timer_set) dont bring up a session which is
	  clearing.
        * bgp_route.c: (general) Update all bgp_table_init calls.
          (bgp_process_{rsclient,main}) clear_node is serialised
          via PEER_STATUS_CLEARING and fsm now.
          (struct bgp_clear_node_queue) can be removed. struct bgp_node
          can be the queue item data directly, as struct peer can be
          kept in the new wq global user data and afi/safi can be
          retrieved via bgp_node -> bgp_table.
          (bgp_clear_route_node) fix to get peer via wq->spec.data,
          afi/safi via bgp_node->bgp_table.
          (bgp_clear_node_queue_del) no more item data to delete, only
          unlock the bgp_node.
          (bgp_clear_node_complete) only need to unset CLEARING flag
          and unlock struct peer.
          (bgp_clear_node_queue_init) queue attaches to struct peer
          now. record peer name as queue name.
          (bgp_clear_route_table) If queue transitions to active,
          serialise clearing by setting PEER_STATUS_CLEARING rather
          than plugging process queue, and lock peer while queue
          active.
          Update to pass only bgp_node as per-queue-item specific data.
	* bgp_vty.c: (bgp_show_summary) Add a 'Clrng' sub-description
	  to state of peer while it's suppressed due to clearing.

2006-02-18 Paul Jakma <paul.jakma@sun.com>

	* bgp_routemap.c: (route_set_community) Quick, very hacky, fix
	  for the set-community leak, bug #89. True fix will be to
	  detangle the web of *_intern caching and provide saner object
	  caching for Quagga, future work.
	* bgp_route.c: (bgp_announce_check) trivial, move declaration
	  of two local variables into the only block where they are
	  used, to aid the reader.

2006-02-05 Paul Jakma <paul.jakma@sun.com>

	* bgp_route.h: Add BGP_INFO_COUNTED to track whether
	  prefix has been counted or not.
	* bgp_route.c: (bgp_pcount_{inc,dec}rement) new helpers, to
	  centralise inc/dec of prefix-count, 
	  (bgp_rib_remove) Remove pcount decrement, use helper.
	  (bgp_rib_withdraw) ditto, additionally use previous function
	  too.
	  (bgp_update_main) Use pcount helpers.
	  (bgp_clear_route_node) ditto, aslo REMOVED routes don't need
	  clearing.
	* bgp_aspath.c: (aspath_gettoken) fix gcc warning about
	  possible uninitialised usage.
 
2006-02-02 Paul Jakma <paul.jakma@sun.com>

	* bgp_route.c: (bgp_{clear_node,process}_queue_init) delay
	  field is removed from workqueue spec.

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

	  (aspath_hash_alloc) aspath_dup already set the aspath
	  string - fix leak.
	  (aspath_parse) aspath_hash_alloc dupes the entire aspath,

          specs and shut up gcc, which complains about cast from void
          via function parameters, for some dumb reason. Do the cast
          inside the function instead.
          (bgp_process_main,bgp_processq_del) ditto.
          (bgp_clear_route_node) ditto.

	  Use LDADD.
	* bgp_aspath.h:	
	  (struct assegment) New struct, abstract representation of a
	  list of AS_PATH segments and the contained ASNs.	  
	  (struct aspath) Remove the raw-data related
	  fields, reference the abstract struct assegment instead. 
	  Remove several other computed fields, it's just a
	  headache to maintain them and they're cheap to compute from
	  struct assegment.
	  (aspath_parse) parse a stream, not a pointer to raw data.
	  (aspath_count_{hops,confeds,size}) helpers to access
	  information formerly directly contained in struct aspath.
	  (aspath_snmp_pathseg) Helper for SNMP, BGP MIB wants
	  to be able to output hex representation of raw data.
	* bgp_aspath.c: (general) partial-rewrite. Store aspath data
	  as an abstract singly-linked list of abstract segments,
          rather than storing the raw data, and parsing it each and
	  every time. Remove several count/size fields which are cheap
	  to compute from the abstract segment structure.
	  (global) Include stream.h, needed for aspath_parse, and
	  others. Couple of helper macros added.
	  (struct assegment_header) Just the header, and only the
	  header.

	  AS_SEG_DATA allocation, the dynamic, per-segment array of
	  ASNs.
	  (assegment_{new,free,free_all,dup,dup_all}) convenience
	  functions for creating struct assegments. The _all forms will
	  follow the entire chain of segments from the given segment.
	  (assegment_prepend_asns) new function, prepend an ASN N times

	  (assegment_normalise) new function. Normalise the given
	  segment chain to meet expectations of Quagga, and to
	  eliminate differing raw representations of the same paths.
	  Merge 'runs' of SEQUENCEs into one segment as our internal
	  segment is not limited by the protocol AS_PATH segment
	  length. Sort ASNs in SETs. 
	  (aspath_new) Take void argument to quell warnings. Use the
	  assegment convenience functions.
	  (assegment_count_{asns,confeds,hops}) new functions to
	  compute at runtime values previously held in struct aspath.
	  (aspath_size) ditto.
	  (aspath_make_str_count) rewritten to stringify new
	  representation, and to be slightly easier to understand
	  hopefully.
	  (aspath_str_update) convenience function, update the aspath
	  str. Should investigate removing maintained string from
	  struct aspath, just run-time compute it, as per other fields.
	  It's just a maintenance headache, would save noticeable
	  amount of RAM with possibly not much extra run-time cost.
	  (aspath_dup) use the assegment dup functions.
	  (aspath_hash_alloc) Take void * argument to satisfy gcc. Use
	  the proper helper functions to dup data.
	  (assegments_parse) new function. parse raw AS_PATH data into
	  struct assegments. Normalise and return the head of the list.
	  (aspath_parse) Parse a stream, not pointer to raw data and
	  use assegments_parse to do it.
	  (assegment_data_put) Write out a single segment data in protocol
	  form to stream.
	  (assegment_header_put) ditto but for segment header.
	  (aspath_put) new function. As per previous but for an entire
	  struct aspath.
	  (aspath_snmp_pathseg) wrapper around aspath_put for
	  bgp_snmp.c. Uses a static buffer sadly.
	  (aspath_aggregate_as_set_add) rewritten to use assegments.
	  (aspath_aggregate) ditto
	  (aspath_{firstas,loop,private_as}_check) ditto
	  (aspath_{merge,prepend,add_one_as}) ditto
	  (aspath_cmp_left{_confed}) ditto
	  (aspath_delete_confed_seq) ditto, plus fixed to properly
	  delete all leading confed segments.

	  (enum as_token) Add values for confeds
	  (aspath_gettoken) Add support for confeds
	  (aspath_str2aspath) ditto
	  (aspath_key_make) updated to use as_segments. Also, add
	  segment type into the hash value as appropriate.
	  (aspath_cmp) updated to use as_segments.
	  (aspath_print) don't segfault on NULL argument.
	* bgp_attr.c: (bgp_attr_aspath) aspath_parse wants the stream
	  now. No need for manual forwarding of stream.

	  segment field, length is gone.
	  Use aspath_size() to determine size.
	  (bgp_attr_init) Fix declaration, explicitely specify void
	  arg.
	  (bgp_dump_routes_attr) Use aspath_size() to determine size.
	* bgp_route.c: (bgp_info_cmp) use the aspath_count_* functions.
	  (bgp_rib_withdraw) remove unused variable. Use
	  aspath_count_hops.
	* bgp_snmp.c: (bgp4PathAttrTable) raw data is gone, use 
	  aspath_snmp_pathseg to get the representation.

2005-09-10 Paul Jakma <paul.jakma@sun.com>

	* bgp_vty.c: (bgp_vty_init) gcc 4 compile fix. static

	  route which should generally be ignored.
	* bgp_route.c: (bgp_info_delete) Just set the REMOVE flag, rather 
	  than doing actual work, so that bgp_process (called directly,
	  or indirectly via the scanner) can catch withdrawn routes.
	  (bgp_info_reap) Actually remove the route, what bgp_info_delete
	  used to do, only for use by bgp_process.
	  (bgp_best_selection) reap any REMOVED routes, other than the old
	  selected route.
	  (bgp_process_rsclient) reap the old-selected route, if appropriate
	  (bgp_process_main) ditto
	  (bgp_rib_withdraw, bgp_rib_remove) make them more consistent with
	  each other. Don't play games with the VALID flag, bgp_process
	  is async now, so it didn't make a difference anyway.
	  Remove the 'force' argument from bgp_rib_withdraw, withdraw+force
	  is equivalent to bgp_rib_remove. Update all its callers.
	  (bgp_update_rsclient) bgp_rib_withdraw and force set is same as
	  bgp_rib_remove.
	  (route_vty_short_status_out) new helper to print the leading

	* bgp_route.c: Remove all code related to VTY_CONTINUE; this feature
	  is deprecated because the output did not represent a single point

	   flap_route_vty_out) Remove code to count number of lines of output,
	   since this was only useful for VTY_CONTINUE behavior.

	  (bgp_show_table) Remove hooks for VTY_CONTINUE callback support.
	  As a result, there's a new output_arg argument to this function.
	  Make function static.
	  (bgp_show) Make function static and add a new output_arg argument.
	  Change all functions that call bgp_show or bgp_show_table to
	  pass the new output_arg argument (that used to be passed inside
	  vty->output_arg).
	* bgp_mplsvpn.c: Remove declarations of functions defined in
	  bgp_route.c; these declarations belong in bgp_route.h.
	* bgp_route.h: Declare 3 global functions used in both bgp_route.c
	  and in bgp_mplsvpn.c.

          should use something like the VTY_GET_INTEGER macro, but without
          the vty_out bits..
        * bgp_routemap.c: (set_aggregator_as) use VTY_GET_INTEGER_RANGE
          (no_set_aggregator_as) ditto.
        * bgpd.c: (peer_uptime) fix unlikely bug, where no buffer is 
          returned, add comments about troublesome return value.
