+
+ * (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.
