bgpd/ChangeLog

2008-03-13 Paul Jakma <paul.jakma@sun.com>

	* (various) Remove 0 entries from struct message's, unneeded due to
	  recent improvements in mes_lookup/LOOKUP.

2008-01-29 Jorge Boncompte <jorge@dti2.net>

	* bgp_network.c: (bgp_socket) IPv4-only version crashes if -l is not
	  used as address will be null.

2007-12-22 Paul Jakma <paul.jakma@sun.com>

	* Fix series of vulnerabilities reported by "Mu Security
	  Research Team", where bgpd can be made to crash by sending
	  malformed packets - requires that bgpd be configured with a
	  session to the peer.
	* bgp_attr.c: (bgp_attr_as4_path) aspath_parse may fail, only
	  set the attribute flag indicating AS4_PATH if we actually managed
	  to parse one.
	  (bgp_attr_munge_as4_attrs) Assert was too general, it is possible
	  to receive AS4_AGGREGATOR before AGGREGATOR.
	  (bgp_attr_parse) Check that we have actually received the extra
	  byte of header for Extended-Length attributes.
	* bgp_attr.h: Fix BGP_ATTR_MIN_LEN to account for the length byte.
	* bgp_open.c: (cap_minsizes) Fix size of CAPABILITY_CODE_RESTART,
	  incorrect -2 left in place from a development version of as4-path
	  patch.
	* bgp_packet.c: (bgp_route_refresh_receive) ORF length parameter
	  needs to be properly sanity checked.
 
2007-12-18 Denis Ovsienko

	* bgp_routemap.c: (no_set_aspath_prepend) This command cancelled
	  existing "set" command regardless if "no set" matched it or not.
	  Fixed.

2007-11-13 Paul Jakma <paul.jakma@sun.com>

	* bgp_main.c: Small fix, format string parameters should never
	  be NULL - it's not strictly valid and some libc's don't let
	  you away with.

2007-10-30 Nick Hilliard <nick@inex.ie>

	* bgp_main.c: Add 'listenon' argument, to pass address to bind
	  to.
	* bgp_network.c: (bgp_socket) Extend to take bind address.
	* bgpd.c: (bgp_init) Pass stored address.
	* bgpd.h: (struct bgp_master) storage for bind address

2007-09-27 Paul Jakma <paul.jakma@sun.com>

	* bgp_aspath.c: (assegment_normalise) remove duplicates from
	  from sets.
	  (aspath_reconcile_as4) disregard a broken part of the RFC around
	  error handling in path reconciliation.

2007-09-25 Paul Jakma <paul.jakma@sun.com>

	* bgp_open.c: (peek_for_as4_capability) Fix to work.
	* bgp_packet.c: (bgp_open_receive) Fix sanity check of as4.
	
2007-09-18 Paul Jakma <paul.jakma@sun.com>

	* bgp_open.c: (bgp_capability_as4) debug printf inline with others.
	  (peek_for_as4_capability) There's no need to signal failure, as
	  failure is better dealt with through full capability parser -
	  just return the AS4, simpler.
	* bgp_packet.c: (bgp_open_receive) Update to match
	  peek_for_as4_capability change.
	  Allow use of BGP_AS_TRANS by 2b speakers.
	  Use NOTIFY_OPEN_ERR rather than CEASE for OPEN parsing errors.
	  (bgp_capability_msg_parse) missing argument to debug print
	  (bgp_capability_receive) missing return values.
	  
	  
2007-07-25 Paul Jakma <paul.jakma@sun.com>

	* Remove 2-byte size macros, just make existing macros take
	  argument to indicate which size to use.
	  Adjust all users - typically they want '1'.
	* bgp_aspath.c: (aspath_has_as4) New, return 1 if there are any
	  as4's in a path.
	  (aspath_put) Return the number of bytes actually written, to
	  fix the bug Juergen noted: Splitting of segments will change
	  the number of bytes written from that already written to the
	  AS_PATH header.
	  (aspath_snmp_pathseg) Pass 2-byte flag to aspath_put. SNMP
	  is still defined as 2b.
	  (aspath_aggregate) fix latent bug.
	  (aspath_reconcile_as4) AS_PATH+NEW_AS_PATH reconciliation
	  function.
	  (aspath_key_make) Hash the AS_PATH string, rather than
	  just taking the addition of assegment ASes as the hash value,
	  hopefully sligthly more collision resistant.
	  (bgp_attr_munge_as4_attrs) Collide the NEW_ attributes
	  together with the OLD 2-byte forms, code Juergen
	  had in bgp_attr_parse but re-organised a bit.
	  (bgp_attr_parse) Bunch of code from Juergen moves
	  to previous function.
	  (bgp_packet_attribute) Compact significantly by
	  just /always/ using extended-length attr header.
	  Fix bug Juergen noted, by using aspath_put's
	  (new) returned size value for the attr header rather
	  than the (guesstimate) of aspath_size() - the two could
	  differ when aspath_put had to split large segments, unlikely
	  this bug was ever hit in the 'wild'.
	  (bgp_dump_routes_attr) Always use extended-len and
	  use aspath_put return for header length. Output 4b ASN
	  for AS_PATH and AGGREGATOR.
	* bgp_ecommunity.c: (ecommunity_{hash_make,cmp}) fix
	  hash callback declarations to match prototypes.
	  (ecommunity_gettoken) Updated for ECOMMUNITY_ENCODE_AS4, 
	  complete rewrite of Juergen's changes (no asdot support)
	* bgp_open.c: (bgp_capability_as4) New, does what it says
	  on the tin.
	  (peek_for_as4_capability) Rewritten to use streams and
	  bgp_capability_as4.
	* bgp_packet.c: (bgp_open_send) minor edit
	  checked (in the abstract at least) with Juergen.
	  Changes are to be more accepting, e.g, allow AS_TRANS on
	  a 2-byte session.
	* (general) Update all commands to use CMD_AS_RANGE.
	* bgp_vty.c: (bgp_clear) Fix return vals to use CMD_..
	  Remove stuff replicated by VTY_GET_LONG
	  (bgp_clear_vty) Return bgp_clear directly to vty.
	  
	
2007-07-25 Juergen Kammer <j.kammer@eurodata.de>

	* bgpd.h: as_t changes to 4-bytes.
	* bgp_aspath.h: Add BGP_AS4_MAX and BGP_AS_TRANS defines.
	* bgp_aspath.c: AS_VALUE_SIZE becomes 4-byte, AS16_VALUE_SIZE
	  added for 2-byte.
	  Add AS16 versions of length calc macros.
	  (aspath_count_numas) New, count number of ASes.
	  (aspath_has_as4) New, return 1 if there are any as4's in a
	  path.
	  (assegments_parse) Interpret assegment as 4 or 2 byte,
	  according to how the caller instructs us, with a new
	  argument.
	  (aspath_parse) Add use32bit argument to pass to
	  assegments_parse. Adjust all its callers to pass 1, unless
	  otherwise noted.
	  (assegment_data_put) Adjust to be able to write 2 or 4 byte
	  AS, according to new use32bit argument.
	  (aspath_put) Adjust to write 2 or 4. 
	  (aspath_gettoken) Use a long for passed in asno.
	* bgp_attr.c: (attr_str) Add BGP_ATTR_AS4_PATH and
	  BGP_ATTR_AS4_AGGREGATOR.
	  (bgp_attr_aspath) Call aspath_parse with right 2/4 arg, as
	  determined by received-capability flag.
	  (bgp_attr_aspath_check) New, code previously in attr_aspath
	  but moved to new func so it can be run after NEW_AS_PATH
	  reconciliation.
	  (bgp_attr_as4_path) New, handle NEW_AS_PATH.
	  (bgp_attr_aggregator) Adjust to cope with 2/4 byte ASes.
	  (bgp_attr_as4_aggregator) New, read NEW_AGGREGATOR.
	  (bgp_attr_parse) Add handoffs to previous parsers for the two
	  new AS4 NEW_ attributes.
	  Various checks added for NEW/OLD reconciliation.
	  (bgp_packet_attribute) Support 2/4 for AS_PATH and
	  AGGREGATOR, detect when NEW_ attrs need to be sent.
	* bgp_debug.{c,h}: Add 'debug bgp as4'.
	* bgp_dump.c: MRTv2 support, unconditionally enabled, which
	  supports AS4. Based on patches from Erik (RIPE?).
	* bgp_ecommunity.c: (ecommunity_ecom2str) ECOMMUNITY_ENCODE_AS4
	  support.
	* bgp_open.c: (peek_for_as4_capability) New, peek for AS4
	  capability prior to full capability parsing, so we know which
	  ASN to use for struct peer lookup.
	  (bgp_open_capability) Always send AS4 capability.
	* bgp_packet.c: (bgp_open_send) AS4 handling for AS field
	  (bgp_open_receive) Peek for AS4 capability first, and figure
	  out which AS to believe.
	* bgp_vty.c: (bgp_show_peer) Print AS4 cap

2007-09-17 Paul Jakma <paul.jakma@sun.com>

	* bgp_open.c: (bgp_capability_mp) We were setting
	  afc_nego[safi][safi] rather than afc_nego[afi][safi], thus
	  failling to announce any non-IPv4 prefixes. Remove the extra,
	  typo-ed character.

2007-09-07 Paul Jakma <paul.jakma@sun.com>

	* (general) bgpd can be made crash by remote peers if debug
	  bgp updates is set, due to NULL pointer dereference.
	  Reported by "Mu Security Research Team",
	  <security@musecurity.com>.
	* bgp_attr.c: (bgp_attr_community) If community length is 0,
	  don't set the community-present attribute bit, just return
	  early.
	* bgp_debug.c: (community_str,community_com2str) Check com
	  pointer before dereferencing.

2007-08-27 Paul Jakma <paul.jakma@sun.com>

	* bgp_route.c: (bgp_announce_check) Fix bug #398, slight
	  modification of Vladimir Ivanov's suggested fix - to keep
	  memory alloc conditional.
	  (bgp_process_announce_selected) Don't take struct attr as
	  argument, none of the callers need it and it needlessly
	  distances allocation from use.
	  Free the extended attr, the attr itself is on the stack. 
	  Fix bad indentation.
	* bgp_attr.c: (bgp_packet_attribute) Remove incorrect assert,
	  and adjust conditional to test attr->extra, diagnosis by
	  Vladimir Ivanov in bug #398.

2007-08-27 Vladimir Ivanov <wawa@yandex-team.ru>

	* bgp_route.c: (bgp_announce_check_rsclient) copy of
	  ri->attr is no longer deep enough, due to addition of
	  attr->extra. It should use bgp_attr_dup, as
	  bgp_announce_check() does.

2007-08-23 Paul Jakma <paul.jakma@sun.com>

	* bgp_regex.c: (bgp_regcomp) Pass NOSUB flag to regcomp to
	  prevent parsing of substitutions, which can have profound
	  performance effects on bgpd and are of no use to the CLI
	  anyway. How much it helps depends on the regex
	  implementation.

2007-07-31 Paul Jakma <paul.jakma@sun.com>

	* (general) Support for draft-ietf-idr-as-pathlimit-03.
	* bgp_attr.h: (struct attr) Add pathlimit struct
          bgp_attr.c: (attr_str) Add BGP_ATTR_AS_PATHLIMIT string.
          (attrhash_key_make) tally pathlimit too
          (attrhash_cmp) cmp pathlimit attr
          (bgp_attr_aspathlimit) New, parse AS_PATHLIMIT attr.
          (bgp_attr_parse) ditto
          (bgp_packet_attribute) Write out AS_PATHLIMIT when set
          (bgp_dump_routes_attr) ditto
         * bgp_route.h: (struct bgp_static) Add TTL field
         * bgp_route.c: (bgp_announce_check) Drop paths that are over
           their hop-count TTL before sending via EBGP.
           Mangle ASN in pathlimit for confeds/private as best we can.
           (bgp_static_update_{rsclient,main}) Add any configure pathlimit
           information.
           (bgp_pathlimit_update_parents) New, update atomic-aggr setting for
           parents of an aspathlimit'ed static.
           (bgp_static_set) Add TTL argument, for all the 'bgp network'
           commands.
           Call previous for TTL changed statics.
           (bgp_static_unset) Call pathlimit_update_parents.
           (various bgp network commands) Add 'pathlimit <0-255>' qualifier
           to all the various forms, bar route-map - which can set ttl
           itself.
         * bgp_routemap.c: (general) Add support for 'set pathlimit ttl' and
           'match pathlimit as'.
           
2007-07-26 Paul Jakma <paul.jakma@sun.com>

	* (general) Clean up and compact capability parsing slightly.
	  Consolidate validation of length and logging of generic TLV, and
	  memcpy of capability data, thus removing such from cap specifc
	  code (not always present or correct).
	* bgp_open.h: Add structures for the generic capability TLV header
	  and for the data formats of the various specific capabilities we
	  support.  Hence remove the badly named, or else misdefined, struct
	  capability.
	* bgp_open.c: (bgp_capability_vty_out) Use struct capability_mp_data.
	  Do the length checks *before* memcpy()'ing based on that length
	  (stored capability - should have been validated anyway on input,
	  but..).
	  (bgp_afi_safi_valid_indices) new function to validate (afi,safi)
	  which is about to be used as index into arrays, consolidates
	  several instances of same, at least one of which appeared to be
	  incomplete..
	  (bgp_capability_mp) Much condensed.
	  (bgp_capability_orf_entry) New, process one ORF entry
	  (bgp_capability_orf) Condensed. Fixed to process all ORF entries.
	  (bgp_capability_restart) Condensed, and fixed to use a
	  cap-specific type, rather than abusing capability_mp.
	  (struct message capcode_str) added to aid generic logging.
	  (size_t cap_minsizes[]) added to aid generic validation of
	  capability length field.
	  (bgp_capability_parse) Generic logging and validation of TLV
	  consolidated here. Code compacted as much as possible.
	* bgp_packet.c: (bgp_open_receive) Capability parsers now use
	  streams, so no more need here to manually fudge the input stream
	  getp.
	  (bgp_capability_msg_parse) use struct capability_mp_data. Validate
	  lengths /before/ memcpy. Use bgp_afi_safi_valid_indices.
	  (bgp_capability_receive) Exported for use by test harness.	  
	* bgp_vty.c: (bgp_show_summary) fix conversion warning
	  (bgp_show_peer) ditto
	* bgp_debug.h: Fix storage 'extern' after type 'const'.

2007-07-31 Lorenzo Colitti <lorenzo@colitti.com>

	* bgp_dump.c: (general) Add comments to code.
	  (bgp_dump_interval_add) remove some redundant lines.
	  (bgp_dump_set) Use enum for type argument.
	  Avoid scheduling dump twice if exact same command
	  is given twice..

2007-06-22 Paul Jakma <paul.jakma@sun.com>

	* bgp_fsm.c: (struct FSM) Bug #368. TCP Errors during OpenSent
	  should cycle to Active, not to Idle or else peer bringup can
	  race and cycle Idle<->Active. Reported and fix tested by
	  Mukesh Agrawal.

2007-05-25 Paul Jakma <paul.jakma@sun.com>

	* bgp_route.c: (bgp_default_originate) Sanity check added
	  previously was broken and always failed, thus this function
	  never could run, bug #370.

2007-05-03 Paul Jakma <paul.jakma@sun.com>

	* bgp_route.h: (struct info) Move less frequently used
	  fields to a lazily allocated struct info_extra.
	  Export bgp_info_extra_get
	* bgp_route.c: (bgp_info_extra_new) allocate extra
	  (bgp_info_extra_free) Free damp info and the info_extra.
	  (bgp_info_extra_get) Retrieve the info_extra of a struct
	  info, allocating as required.
	  (generally) adjust to use info->extra
	* bgp_damp.c: (generally) use bgp_info_extra_get to access
	  dampinfo
	* bgp_attr.h: Move rarely allocated attributes from struct attr
	  to a struct attr_extra, for a substantial saving in size of
	  struct attr.
	* bgp_attr.c: (bgp_attr_extra_{new,free}), new, self-explanatory.
	  (bgp_attr_extra_get) Get the attr_extra for a given struct
	  attr, allocating it if needs be.
	  (bgp_attr_dup) Shallow copy the struct attr and its attr_extra.
	  (generally) adjust to know about attr->extra.
	* bgp_debug.c: (bgp_dump_attr) ditto
	* bgp_vty.c: (show_bgp_memory) print attr and info extra sizes.
	* bgp_nexthop.c: (generally) adjust to know about attr->extra
	  and info->extra.
	* bgp_{packet,routemap,snmp,zebra}.c: ditto

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
	   warnings.

2006-01-17 Paul Jakma <paul.jakma@sun.com>

	* bgp_nexthop.c: (zlookup_read*) convert to new Zserv format.
	  (zlookup_query_ipv6) ditto.
	  (bgp_import_check) ditto.
	  
2006-01-16 Paul Jakma <paul.jakma@sun.com>

	* bgp_aspath.c: (assegment_append_asns) XREALLOC can return
	  NULL theoretically, take care not to lose the allocated data.
	  (aspath_hash_alloc) aspath_dup already set the aspath
	  string - fix leak.
	  (aspath_parse) aspath_hash_alloc dupes the entire aspath,
	  including segments, but we forgot to free the temporary
	  assegment.
	  (aspath_snmp_pathseg) move the static stream pointer out to
	  file scope, so it can be freed.
	  (aspath_finish) new function, free aspath resources.
	* bgp_aspath.h: (aspath_finish) export.

2006-01-10 Juris Kalnins <juris@mt.lv>

	* bgpd.h: (bgp_router_id_unset) ex-function, remove.
	
2005-11-23 Paul Jakma <paul.jakma@sun.com>

	* bgp_aspath.c: (assegments_parse) should be static

2005-11-23 Juergen Kammer <j.kammer@eurodata.de>

	* bgp_aspath.c: (aspath_cmp_left_confed) fix SEGV for case
	  where one or both paths are empty.

2005-11-14 Paul Jakma <paul.jakma@sun.com>

	* bgp_route.c: (bgp_process_rsclient) convert to new workqueue
          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.
          (bgp_clear_node_queue_del) ditto.

2005-11-03 Paul Jakma <paul.jakma@sun.com>

	* bgp_damp.c: (bgp_reuse_timer) struct bgp can be retrieved via
	  the struct bgp_damp_info, no need to guess by using
	  bgp_get_default().

2005-10-01 Andrew J. Schorr <ajschorr@alumni.princeton.edu>

	* bgp_vty.c: (bgp_config_write_redistribute) Use new library function
	  zebra_route_string instead of a local hard-coded table.

2005-09-30 Vincent Jardin <vincent.jardin@6wind.com>

	* bgp_packet.c: fix compilation when DEBUG is used.

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

	* Makefile.am: bgpd shouldn't list libgp's sources as its own.
	  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.
	  (assegment_data_{new,free}) convenience functions for
	  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
	  to segment.
 	  (assegment_append_asns) Append a list (array) of ASNs to
	  segment.
	  (int_cmp) convenience function for the aspath hash.
	  (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.
	  (aspath_as_add) Just use assegment_append_asns.
	  (aspath_segment_add) updated to use assegments.
	  (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.
	  (bgp_packet_attribute) empty aspath is now denoted by NULL

2004-11-04 Andrew J. Schorr <ajschorr@alumni.princeton.edu>

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

	* (global) more const'ification and fixups of types to clean up code.
	* bgp_mplsvpn.{c,h}: (str2tag) fix abuse. Still not perfect,
          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.
	
2004-10-03 James R. Leu <jleu at mindspring.com>
