policy proposal: "Automatic Revocation of Persistently Non-functional Delegated RPKI CAs"
by Job Snijders 25 Apr '25

25 Apr '25

Dear all, I'd like to propose a mechanism to automatically prune dead branches in the RPKI directly subordinate to RIPE NCC. Below is the policy proposal text that I have in mind. In short: RIPE NCC should revoke a Delegated CA's certificate when absolutely no "sign of life" (valid Manifest) has been observed for over a 100 days. It probably is good to have some discussion around: * should perpetually broken Delegated CA setups be culled at some point? * is the continuous lack of a valid current manifest for a 100 day period of time a good indicator for "Delegated CA brokenness"? Your feedback is most welcome! Kind regards, Job ------------------- Policy Proposal Name: Automatic Revocation of Persistently Non-functional Delegated RPKI Certification Authorities Author: a. name: Job Snijders b. email: job(a)sobornost.net Proposal Version: (to be assigned by the RIPE NCC) Submission Date: February 25th, 2025 Suggested RIPE WG for discussion and publication: RIPE Routing Working Group Proposal Type: NEW Policy Term: Indefinite Summary of proposal: RIPE NCC offers users of its RPKI certification service two deployment models: "Hosted CA setup" and "Delegated CA setup". In the Hosted setup RIPE NCC is responsible for timely issuance and publication of new RPKI Manifests and CRLs, but in the Delegated setup users themselves manage their CA on their own infrastructure. It is possible for Delegated CA infrastructure to be offline for extended periods of time or for the contents of publication repositories to become stale or otherwise invalid. This proposal suggests to provide mandate to RIPE NCC to revoke resource certificates associated with longtime non-functional CAs to reduce Relying Party workload. This policy proposal targets only pathologically non-functional CAs. An example of a situation considered out-of-scope for this policy would be a publication repository service advertised to also be available via IPv6 and RRDP but in practise only reachable via IPv4 and Rsync: the associated CA would still be considered functional (provided a valid and current Manifest could somehow be retrieved and validated sometime in the previous one hundred days). In other words: this policy proposal isn't about CAs that didn't achieve 100% uptime, but about CAs that are down all the time. Policy text: If RIPE NCC is unable to discover and validate a Delegated RPKI Certification Authority's (CA's) current Manifest and CRL for one hundred consecutive days, that Delegated CA's resource certificate shall be revoked by the RIPE NCC. RIPE NCC shall make reasonable efforts to discover new Manifests, for example, by corroborating information from multiple vantage points. After revocation, the Resource Holder may either reinitialize the Delegated CA setup or choose the Hosted CA setup. Rationale: a. Arguments supporting the proposal Persistently Non-functional Delegated CAs (PNDCs, for short) have subtle effects within the RPKI ecosystem which may become more pronounced over time. * PNDCs offer nothing of value to RPs (because without a current valid Manifest any signed payloads are unavailable). * RP synchronisation becomes more economic with fewer purposeless caRepositories to traverse. * PNDCs besmirch Relying Party (RP) syslog message archives and waste RP CPU cycles and network traffic. * Automatic revocation is only a minor inconvenience for CAs (that already were non-functional to begin with), but a big deal for RPs - especially when taking into account many future synchronisation attempts over long periods of time. b. Arguments opposing the proposal * Resource holders might require more than one hundred days to complete the initial Delegated CA setup. (Counterpoints: initial setup procedures usually only takes a few minutes. Resource holders are free to simply retry the delegated CA setup procedure following automatic revocation.) Additional opposing arguments to be determined.

Survey on Segment Routing deployment
by Dekinder Florian 14 Mar '25

14 Mar '25

Hello RIPE community, I recently shared a survey (2 months ago) as part of a research project on segment routing (SR) deployment practices among network operators. The goal is to gain insights into how SR is currently deployed and managed across different ASes. If you are involved in SR management in your network and if you missed the first request, I would greatly appreciate your input. The survey takes no more than 5 minutes to complete. https://docs.google.com/forms/d/e/1FAIpQLSd9d77tMC_azhcfWWCMR_nHCBlfzu8VI-v… Thank you in advance for your time and contribution! Best regards, Florian Dekinder

Registry scoped members for RPSL set objects
by Sasha Romijn 21 Feb '25

21 Feb '25

Hello, We would like to share our draft "Registry scoped members for RPSL set objects" with the working group: https://datatracker.ietf.org/doc/draft-romijn-grow-rpsl-registry-scoped-mem… This draft addresses the ambiguity of references between sets in RPSL, where currently one set includes another by its RPSL primary key. As the same primary key may exist in multiple IRR registries, these references are ambiguous, while the referred objects sometimes have very different contents. There was some earlier discussion on the routing-wg list on this issue and how to resolve it, but it didn't lead to any practical solution. This new proposal adds a new attribute where references to other sets must be scoped to a specific IRR registry. Specific resolving and validation rules ensure that we keep backwards compatibility with older RPSL objects, authoritative servers, and resolvers. At the same time, it provides benefits even with partial deployment. We welcome your feedback and discussion, though preferably on the GROW mailing list: https://mailarchive.ietf.org/arch/msg/grow/mdoTvD2vQBZqsDO0VRWRo-ADD3c/ Sasha

RPKI's 2024 Year in Review
by Job Snijders 17 Jan '25

17 Jan '25

Dear all, Happy new year everyone! Having just closed the book on another orbit around the sun - let's look back at how RPKI did in 2024! In this memo I'll share some RPKI statistics, summarize highlights from the IETF Standards Development process, and reflect on emerging trends. Year to Year Growth of the distributed RPKI database =============================================================== A straightforward method to compare 2023 and 2024 is to look at the absolute numbers. The below table was constructed by comparing two December 31st RPKIviews.org snapshots based on the the ARIN, AFRINIC, APNIC, LACNIC, and RIPE NCC Trust Anchors. 2023-12-31 2024-12-31 Total cache size (KiB): 1,546,728 2,021,784 (+31%) Total number of files (objects): 309,802 415,384 (+34%) Wall time validation run (seconds): 163 228 (+40%) Publication servers (FQDNs): 63 53 (-16%) Certification authorities: 40,511 44,935 (+11%) Route origin authorizations: 188,345 280,692 (+49%) Uniq VRPs: 497,341 639,909 (+29%) Average ROAIPAddresses per ROA: 2.7 2.3 (-15%) IPv4 addresses covered: 2,502,293,068 2,726,513,768 (+ 9%) Uniq IPv4 addresses covered: 1,502,281,680 1,658,281,248 (+10%) IPv6 addresses covered: 17,263 * 10^30 17,392 * 10^30 (+ 1%) Uniq IPv6 addresses covered: 15,128 * 10^30 15,139 * 10^30 (+ 0%) Uniq origin ASNs in ROAs: 40,656 47,282 (+16%) Uniq ASPA Customer ASIDs: 56 87 (+55%) The number of IPv4 addresses covered by ROAs saw similar growth compared to 2023. It's not entirely clear to me what's going on with IPv6, but on the IPv6 side of the house growth seems to be stalling. The NIST RPKI Deployment Monitor seems to corroborate these observations: https://rpki-monitor.antd.nist.gov/ROV/20250103.00/All/All/6#div2 As predicted in last year's review, nowadays more than half of both the IPv4 and IPv6 routes in the global routing system are covered by RPKI ROAs (~ 54%). Kentik estimates that around 74% of IP traffic is destined towards ROA covered destinations. These numbers mean it will be worth your while to create and use ROAs for BGP Origin Validation. This year's report includes new metrics: "Uniq ASPA Customer ASIDs", this field provides a simple indicator for global ASPA deployment on the signer side. At the moment about 0.001% of Autonomous Systems in the Internet global routing system published an ASPA record, so it's still very early days for ASPA! Another new metric is "Wall time validation run (seconds)". To produce this metric the two snapshots are processed through the same (modern) RPKI cache implementation on the same hardware omitting any network operations. This metric suggests that as the RPKI grows in size and/or number of files, processing time also increases. Please note that the wall time metric is not comparable between successive annual reports (for example, next year I might have a different laptop, or use a different validator implementation) - but within a single annual report the metric comparison is apples to apples. To reproduce: $ rpki-client -V rpki-client 9.3 $ time rpki-client -P 1704066710 -n -d rpki-20231231T235150Z/data /tmp/ $ time rpki-client -P 1735689171 -n -d rpki-20241231T235251Z/data /tmp/ Onwards to the next metric, "Average ROAIPAddresses per ROA" this shows how many IP prefixes, on average, are contained within a single ROA object. The higher the number of ROAIPAddresses per ROA, the higher computational efficiency is. "Efficiency" in this context arises from validators spending the computational cost of validating a single EE certificate and yielding more than 1 ROAIPAddress. Under the RIPE NCC TAL one yields 6.5 prefixes per ROA, while in the ARIN region this is number is 1.1 prefixes per ROA. As stewards of this technology, we need to keep an eye on the overall efficiency of the RPKI to ensure things don't get out of hand. SIDROPS - Working Group developments =============================================================== Some quick updates from the IETF working group responsible for development and maintenance of the RPKI technology stack! ASPA - where we at? ------------------- While most of the ASPA specification documents are steadily moving towards completion, the RPKI-To-Router (RTR) specification unfortunately appears to be progressing with great difficulty. With so many people excited about the prospect of using ASPA to prevent route leaks, it's sad to see a select few individuals dragging their feet to dot the i's and cross the t's. As things stand, some parts of the draft RTR specification are unimplementable and other parts appear underspecified. Perhaps appointment of an extra document editor would help? In last year's report I was more optimistic about the delivery timeline than I am this year. I now expect publication of the ASPA specs as RFCs not to happen earlier than 2026. For an overview of open action items, see: https://mailarchive.ietf.org/arch/msg/sidrops/fwPjecfnlU5JYi_hU-Sh3o7WRHQ/ Finished work ------------- The good news is that 2024 turned out to be a productive year in terms of tidying up various aspects of the RPKI technology stack. "Tidying up" in this context means resolving potentially detrimental system behavior for some edge cases, resolving underspecification in older documents, and documenting optimizations. A quick overview of RFC publications in the last 12 months: * RFC 9582 - A Profile for Route Origin Authorizations (ROAs) https://www.rfc-editor.org/rfc/rfc9582.html The new ROA specification clarifies the requirements for IP address and AS identifier X.509 certificate extensions, its ASN.1 notation was revised with additional backwards compatible constraints, errata were incorporated, and a canonicalization procedure was specified for the content of ipAddrBlocks. * RFC 9589 - On the Use of the CMS Signing-Time Attribute in RPKI Signed Objects https://www.rfc-editor.org/rfc/rfc9589.html 9589 describes mechanism for a 'cross-layer optimization' which enables Relying Parties (RPs) - when switching from RRDP to RSYNC - to save on bandwidth consumption. All five RIRs and rpki-client support this mechanism. See the following deep-dive for more information: https://blog.apnic.net/2023/12/04/using-timestamps-inside-rpki-objects-to-o… * RFC 9674 - Same-Origin Policy for the RRDP https://www.rfc-editor.org/rfc/rfc9674.html A potential security issue was discovered in RRDP: from one RRDP server references could be made to resources hosted on another RRDP server, causing RPs to follow the reference and waste bandwidth. The solution turned out to be simple: RPs should not follow references to resources hosted on other origins. All actively-maintained RPs implementations adopted this approach. * RFC 9697 - Detecting RRDP Session Desynchronization https://www.rfc-editor.org/rfc/rfc9697.html For RRDP to work well, once Delta files are published, Deltas are not expected to change over time. Delta files are immutable. A mechanism was devised for RPs to detect occurrences of unexpected file mutations and how to recover. Most actively-maintained RP implementations adopted this approach. Final words =============================================================== RPKI has become the #1 tool in the toolbox to prevent routing incidents. Implementing RPKI allows operators to improve network reliability by strengthening the security and integrity of the global Internet routing system. I'm excited to see what the coming year will bring!

RSYNC vulnerabilities and RPKI
by Tim Bruijnzeels 16 Jan '25

16 Jan '25

Dear all, As you may have heard through other channels, six vulnerabilities have been identified in RSYNC: https://vulnerability.circl.lu/bundle/d938dc28-6877-40db-ad5f-25f3051288e6 We would like to note that two of the vulnerabilities affect rsync servers but the RIPE NCC RPKI RSYNC repository was not affected by these vulnerabilities. RIPE NCC RRDP and RSYNC repositories are operated independently, taking their data from a common internal source. Therefore issues with one protocol cannot affect the other protocol. As mentioned, the RIPE NCC RSYNC server was not affected, but even if it had been, any issues would not have affected the content of the RRDP repository. The other vulnerabilities affect rsync clients. RPKI validators have a preference for retrieving RPKI data using the RRDP (HTTPS based) protocol, but fall back to RSYNC if RRDP is unavailable. If you operate an RPKI validator, we recommend that you either: - Upgrade your rsync client to 3.4.1 (or higher when available); or - Upgrade your rsync client to a patched version provided by your OS vendor; or - Look into using openrsync Kind regards, Tim Bruijnzeels Principal Engineer RPKI RIPE NCC

Survey on Segment Routing Deployment
by Dekinder Florian 15 Jan '25

15 Jan '25

Hello RIPE community, I am conducting a survey as part of a research project on segment routing (SR) deployment practices among network operators. The goal is to better understand the current state of SR deployment and how its management varies across ASes. If you are involved in the management of SR in your network (or have information about it), I would greatly appreciate your input. The survey should take no more than 5 minutes to complete. Below is the link to the survey: https://docs.google.com/forms/d/e/1FAIpQLSd9d77tMC_azhcfWWCMR_nHCBlfzu8VI-v… Best regards, Florian Dekinder University of Liège, Belgium
