Paul Jakma 0b2aa3a0a8 [bgpd] Merge AS4 support 
2007-10-14 Paul Jakma <paul.jakma@sun.com>

	* NEWS: Note that MRT dumps are now version 2
	* (general) Merge in Juergen Kammer's AS4 patch.

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.
	* aspath_test.c: Test dupe-weeding from sets.
	  Test that reconciliation merges AS_PATH and AS4_PATH where
	  former is shorter than latter.

2007-09-26 Paul Jakma <paul.jakma@sun.com>

	* aspath_test.c: Test AS4_PATH reconcilation where length
	  of AS_PATH and AS4_PATH is same.

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.
	* tests/bgp_capability_test.c: (general) Extend tests to validate
	  peek_for_as4_capability.
	  Add test of full OPEN Option block, with multiple capabilities,
	  both as a series of Option, and a single option.
	  Add some crap to beginning of stream, to prevent code depending
	  on getp == 0.

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.
	* tests/bgp_capability_test.c: (parse_test) update for changes to
	  peek_for_as4_capability

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.
	* tests/aspath_test.c: Exercise 32bit parsing. Test reconcile
	  function.
	* tests/ecommunity_test.c: New, test AS4 ecommunity changes,
	  positive test only at this time, error cases not tested yet.

2007-07-25 Juergen Kammer <j.kammer@eurodata.de>

	* (general) AS4 support.
	* 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
	* tests/aspath_test.c: Support asn32 changes, call aspath_parse
	  with 16 bit.
	* vtysh/extract.pl: AS4 compatibility for router bgp ASNUMBER
	* vtysh/extract.pl.in: AS4 compatibility for router bgp ASNUMBER
	* vtysh/vtysh.c: AS4 compatibility for router bgp ASNUMBER
