rpki-client: Release Notes

rpki-client Release Notes rpki-client 9.9 (2026-08-22) txt, tar.gz rpki-client 9.9 has just been released and will be available in the rpki-client directory of any OpenBSD mirror soon. It is recommended that all users upgrade to this version for improved reliability. rpki-client is a FREE, easy-to-use implementation of the Resource Public Key Infrastructure (RPKI) for Relying Parties to facilitate validation of BGP announcements. The program queries the global RPKI repository system and validates untrusted network inputs. The program outputs validated ROA payloads, BGPsec Router keys, and ASPA payloads in configuration formats suitable for OpenBGPD and BIRD, and supports emitting CCR, CSV, and JSON for consumption by other routing stacks. See RFC 6480 and RFC 6811 for a description of how RPKI and BGP Prefix Origin Validation help secure the global Internet routing system. rpki-client was primarily developed by Kristaps Dzonsons, Claudio Jeker, Job Snijders, Theo Buehler, Theo de Raadt, and Sebastian Benoit as part of the OpenBSD project. This release includes the following changes to the previous release: - Introduce a backoff retry mechanism for non-functional CAs, eventually settling on retrying broken CAs only once per day. Backoff helps reduce load on both the RP itself and the publication points. It reduces log clutter and improves RP run duration. - Support for OpenSSL 4. - Add additional fail safe: only output config files on successful run. - In Rsync mode, include .gbr files in transfer for backwards compatibility. - Exclude hidden files and directories ('/.*') when synchronizing via Rsync. From a report by Ben Cartwright-Cox. - Limit the length of filenames as they appear in various ASN.1 fields to 255. - Improve readability by printing CCR ManifestState sorted by AKI. - Improve warnings related to malformed CCRs. Reliability fixes: - Limit the range of deltas added to the queue. Reported by Xin Wang. - Rework error handling in rrdp_handle_file. Reported by Xin Wang. - Ensure consistent states in persistent HTTP connections. Reported by Xin Wang. - Tighten well-formedness checks on AIA & SIA extensions in certs. Reported by Ties de Kock. - Clear last_modified after each response on a persistent HTTP connection. Reported by Ties de Kock. - ASPAs with too many providers are no longer included in CCR output. Reported by Ties de Kock. - Replace assert() with a graceful failure by aborting the http request. Reported by Frank Denis. - Fix an off-by-one error in the internal IP address overlap checker. Reported by Frank Denis. rpki-client works on all operating systems with a libcrypto library based on OpenSSL 1.1 or later, LibreSSL 3.6, a libtls library compatible with LibreSSL 3.6 or later, expat and zlib. rpki-client is known to compile and run on at least the following operating systems: Alpine, CentOS, Debian, Fedora, FreeBSD, Red Hat, Rocky, Ubuntu, macOS, and of course OpenBSD! It is our hope that packagers take interest and help adapt rpki-client-portable to more distributions. The mirrors where rpki-client is available can be found on https://www.rpki-client.org/portable.html Reporting Bugs: =============== General bugs may be reported to tech@openbsd.org Portable bugs may be filed at https://github.com/rpki-client/rpki-client-portable We welcome feedback and improvements from the broader community. Thanks to all of the contributors who helped make this release possible. Assistance to coordinate security issues is available via security@rpki-client.org. rpki-client 9.8 (2026-04-14) txt, tar.gz rpki-client 9.8 has just been released and will be available in the rpki-client directory of any OpenBSD mirror soon.

This release includes the following changes to the previous release: - Various refactoring for improved compatibility with various libcrypto implementations and in CA/BGPsec certificate handling. - Fixed an accounting issue in HTTP gzip compression detection. - Added a warning in extra verbose mode (-vv) about standards non-compliant Issuer and Subject ASN.1 string encodings. - Added a check for canonical encoding of ASPA eContent in alignment with draft-ietf-sidrops-aspa-profile-22. - Ensure that a repository timeout correctly stops repository processing. Thanks to Fedor Vompe from Deutsche Telekom for reporting. - Fixed a defect in Canonical Cache Representation ROAIPAddressFamily sort order. As a result, rpki-client 9.8 cannot parse rpki-client 9.7's .ccr files and vice versa. Thanks to Bart Bakker from RIPE NCC for reporting. - Fixed an issue in the parser for the locally configured constraints. Thanks to Daniel Anderson. - A malicious RRDP Publication Server can cause a NULL dereference. Thanks to Daniel Anderson for reporting. - A malicious RPKI Publication Server can cause an incorrect error exit. Thanks to Yuheng Zhang, Qi Wang, Jianjun Chen from Tsinghua University, and Teatime Lab for reporting. rpki-client works on all operating systems with a libcrypto library based on OpenSSL 1.1 or later, LibreSSL 3.6, a libtls library compatible with LibreSSL 3.6 or later, expat and zlib. rpki-client is known to compile and
