* Changes in Quagga 0.99.2
+- [bgpd] 4-byte AS support added
+- [bgpd] MRT format changes to version 2. Those relying on
+ bgpd MRT table dumps may need to update their tools.
+
+* Changes in Quagga 0.99.2
+
- [bgpd] Work queues added to bgpd to split up update processing,
particularly beneficial when a peer session goes down. AS_PATH
parsing rewritten to be clearer, more robust and ready for 4-byte.

+
+ * 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>
+
+ * (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
