We have released OpenBGPD 8.5, which will be arriving in the OpenBGPD directory of your local OpenBSD mirror soon.
This release includes the following changes to the previous release: * 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. OpenBGPD-portable is known to compile and run on FreeBSD and the Linux distributions Alpine, Debian, Fedora, RHEL/CentOS and Ubuntu. It is our hope that packagers take interest and help adapt OpenBGPD-portable to more distributions. We welcome feedback and improvements from the broader community. Thanks to all of the contributors who helped make this release possible.
