[dependabot]

Bumps bgpkit-parser from 0.16.0 to 0.17.0.

Release notes

Sourced from bgpkit-parser's releases.

v0.17.0

New features

• Minimal route-level parser: Added BgpRouteElem and into_route_iter() / into_fallible_route_iter() for fast scans when only prefix, AS path, peer metadata, and timestamp are needed (thanks @​ties for the contribution).

  • BgpRouteElem struct with Option<Arc<AsPath>> — shares the same parsed AS path across all announced prefixes from a single BGP UPDATE via Arc
  • RouteIterator and FallibleRouteIterator for MRT records (BGP4MP, TableDump v1/v2, IPv4/IPv6, add-path)
  • Filter support shared via RouteFilterView trait: origin_asn, prefix, peer_ip, peer_asn, type, ts_start/ts_end, as_path, ip_version all match identically to BgpElem
  • Community filters fail-closed (return no match) since communities are not parsed at the route level
  • Trait parity with BgpElem: Display (PSV-style), Eq, PartialOrd, Ord all implemented
  • Performance: ~10-15% faster on updates files, ~50-70% faster on RIB dumps
  • Added examples/route_level_parsing.rs demonstrating performance comparison

• RFC 3107/8277 MPLS Labeled NLRI support: Added parsing and encoding for BGP MPLS Labeled NLRI (SAFI 4). Note: RFC 8277 obsoletes RFC 3107; both are supported for compatibility:

  • New MplsLabel type with label value, TC, S-bit, and TTL
  • LabeledNetworkPrefix combining prefix with label stack (SmallVec<[MplsLabel; 2]>)
  • LabeledNlriConfig for configurable parsing modes; default is MultiLabel (handles both single and stacked labels)
  • Safi::MplsLabel = 4 added to SAFI enum
  • Nlri struct (inner type of MpReachNlri/MpUnreachNlri) updated with labeled_prefixes field for MPLS announcements
  • Error variants for labeled NLRI parsing failures

Performance improvements

• Route-level parsing: Selective attribute parsing skips communities, MED, next-hop, local-pref, and other attributes not needed for route identity. Combined with Arc<AsPath> sharing across prefixes from the same message, this yields ~10-15% faster updates parsing and ~50-70% faster RIB dump parsing.

• AS Path memory optimization: Reduced allocations for common cases using smallvec (thanks @​ties for the contribution):

  • AsPath::segments: Uses SmallVec<[AsPathSegment; 1]> — 99.99% of routes have exactly 1 segment (zero-allocation coverage)
  • AsPathSegment variants: Uses SmallVec<[Asn; 6]> — 90.85% of segments have ≤6 ASNs (zero-allocation coverage)
  • Based on RIB analysis of 200K records from route-views2 (3.29M segments analyzed)

Breaking changes

• Nlri struct: Added labeled_prefixes: Option<Vec<LabeledNetworkPrefix>> field. This field is None for all non-MPLS routes (SAFI ≠ 4) and is populated only when safi == Safi::MplsLabel. If you pattern-match or destructure Nlri, add .. or handle the new field. No behavior change for existing IPv4/IPv6 unicast parsing.

Fixed

• RFC 4760 mandatory attribute validation: Fixed validation to properly handle multiprotocol BGP (MP-BGP) conditional mandatory attributes (thanks @​ties for the contribution):
  • Pure withdrawals (no announcements): no mandatory attributes required
  • MP_REACH_NLRI only: ORIGIN and AS_PATH required, NEXT_HOP not required (embedded in MP_REACH_NLRI)
  • IPv4 NLRI: ORIGIN, AS_PATH, and NEXT_HOP all required
  • Mixed (IPv4 NLRI + MP_REACH_NLRI): ORIGIN, AS_PATH required; NEXT_HOP required because IPv4 NLRI is present

Added

• AttributeValidationState: Extracted reusable validation struct from parse_attributes() so that both full attribute parsing and route-level parsing share identical RFC 7606 / RFC 4271 validation logic.

• RouteFilterView trait: New internal trait that enables sharing filter matching logic between BgpElem and BgpRouteElem. Community filters return false for route elements since communities are not parsed.
