OpenBGPD 8.5 💾

OpenBGPD is a free implementation of the Border Gateway Protocol (BGP), Version 4. It allows ordinary machines to be used as routers exchanging routes with other systems speaking the BGP protocol. The portable version (e.g. for Linux) does not have the means to influence kernel routing tables. It is only suitable for route servers/collectors.

major bugfix: Include OpenBSD 7.5 errata 004: Repair a withdraw desyncronization problem in bgpd(8). Affected are OpenBGPD 8.2, 8.3 and 8.4. Fix Linux TCP MD5 autoconf detection and improve the code to work in all cases. Double peer description length to 64 characters. Improve handling of bgpd AFI IPv4 sessions over IPv6 only links. Sessions over IPv6 link-local addresses are now always considered to be connected. Allow operators to enforce the presence of certain capabilities. Improve capability negotiation and remove 'announce capabilities'. The 'announce capabilities yes no ' neighbor config option needs to be removed from configuration files. Instead individual capabilities need to be disabled. Improve negotiation of the multi-protocol capability and the fallback to IPv4 only mode. Mark RTR and IPv6 BGP packets with DSCP CS6 (network control). Increase RTR PDU limit to 48k and limit number of SPAS to 10'000. Convert the remaining session engine parsers to the new ibuf API. Various changes to autoconf and portable headers for NetBSD support.

rpki-client 9.1

The OpenBSD rpki-client is a free, easy-to-use implementation of the Resource Public Key Infrastructure (RPKI) for Relying Parties (RP) to facilitate validation of the Route Origin of a BGP announcement. The program queries the RPKI repository system, downloads and validates Route Origin Authorisations (ROAs) and finally outputs Validated ROA Payloads (VRPs) in the configuration format of OpenBGPD, BIRD, and also as CSV or JSON objects for consumption by other routing stacks.
