Open-sourcing of the RIPE NCC’s RPKI core software
by Bart Bakker 16 Feb '22

16 Feb '22

Dear colleagues, We are pleased to announce that we have published the source code used by the RIPE NCC for the RPKI back-end (the RPKI core) under the 3-Clause BSD licence on Github: https://github.com/RIPE-NCC/rpki-core <https://github.com/RIPE-NCC/rpki-core> The RPKI core is the RIPE NCC's software for creating and maintaining RPKI objects based on the registry's current status and publishing these in the repositories. The RIPE NCC hosts the authoritative repository internally. We use the repository on Github to publish the source code externally. The first commit is identical to the source code in the RIPE NCC's internal repository at the time of that commit. The changes between releases are squashed and published to this repository on deployment, and the `main` branch reflects the code used by the production CA. We encountered several challenges while preparing this project for an open-source release. The main challenges were that the system uses proprietary elements that were part of the revision history and cannot be made public. Furthermore, it was not possible to review all historic commits. We plan to present our challenges while open-sourcing this project at RIPE 84. If you have any questions about this change, please contact the RIPE NCC's RPKI team at rpki(a)ripe.net <mailto:rpki@ripe.net>. Kind Regards, Bart Bakker Senior Software Engineer RIPE NCC

I imagine it'll be educational for the community to > be able to follow the train of thought and storyline of future > developments. I think this would be good, unless you really need to for some reason, try to avoid squashing future commits. P.S. I just subscribed to the list so I can't easily reply normally, but imagine this is a reply to: "Open-sourcing of the RIPE NCC’s RPKI core software" https://www.ripe.net/ripe/mail/archives/routing-wg/2022-February/004510.html -Cynthia

Decommissioning public experimental rsync environment (rpki2.ripe.net)
by Ties de Kock 07 Feb '22

07 Feb '22

Dear colleagues, Over the last months, we ran a public experimental rsync environment on rsync://rpki2.ripe.net [0]. This environment uses an internal RRDP publication server as a source of truth and writes snapshots of that state to disk. Rsync then served files from the local filesystem instead of NFS. We observed improved performance and scalability compared to our NFS based rsync setup and will consider this setup when revisiting our rsync infrastructure. We have concluded this experiment and will decommission this environment. Kind regards, Ties de Kock [0]: https://www.ripe.net/ripe/mail/archives/routing-wg/2021-May/004345.html

Issues with RIPE NCC services affecting RPKI
by Ties de Kock 21 Jan '22

21 Jan '22

Dear colleagues, Friday 21 January, starting around 08:10 UTC, some of the RPKI services were unavailable due to network issues. The affected services include both the CA system, the RPKI dashboard on my.ripe.net, and rsync://rpki.ripe.net. One effect of these issues was limited internal connectivity. Due to this, we disabled the RPKI CA system. No objects were created or updated during this period. We re-enabled the CA system around 09:20 UTC when internal connectivity had recovered. We will keep monitoring the situation. Kind regards, Ties de Kock

Dear colleagues, We have now published our quarterly planning for Q1 2022 for RPKI: https://www.ripe.net/manage-ips-and-asns/resource-management/rpki/rpki-plan… <https://www.ripe.net/manage-ips-and-asns/resource-management/rpki/rpki-plan…> We’re still working on finishing some loose ends from Q4 2021, for example open sourcing the RPKI core code and finishing the final step for the HSM migration and we’ll announce here on the list when this has finished. Our goals are to make it clear what we are working on in the coming months, and also to get discussion around those plans so we can make developments based on community input. If you have comments or questions around this, we hope you'll discuss with us on the list or you can always contact the team directly at rpki(a)ripe.net <mailto:rpki@ripe.net>. Kind regards, Nathalie Trenaman Routing Security Programme Manager RIPE NCC

Penetration Test Report for RPKI
by Bart Bakker 27 Dec '21

27 Dec '21

Dear colleagues, We are continuing our efforts to strengthen the security, compliance, and transparency of the RPKI system. Following on from last year's work, we asked an external party, Radically Open Security (ROS), to carry out a penetration test of our RPKI software from a user perspective earlier this year. ROS has shared a penetration test report on their findings. This testing complements the source code audit report published on 3 December. You can now find the Penetration Test Report by Radically Open Security and our response to their findings on our website [0]. We hope you will find these reports useful, and we look forward to your feedback.

RPKI ROA MaxLength - feature or misfeature? (UX/security)
by Job Snijders 11 Dec '21

11 Dec '21

Hi all, I'm writing the working group to initiate some conversation about a long-standing point of confusion in the RPKI ecosystem: the ROA MaxLength field. What is the ROA MaxLength field? ================================ The data format profile of RPKI ROAs allows an operator to specify the following fields: * 1 (one) Origin AS * one or more IPv4 or IPv6 prefixes * for each IP prefix, a so-called 'MaxLength' value Operators are allowed to create multiple ROAs with different Origin ASNs covering the same prefix, folks can mix-and-match as needed. The "MaxLength" feature essentially is a macro function (a 'shortcut'): when you create a ROA with the following parameters: Prefix: 2001:67c:208c::/48 MaxLength: 50 Origin AS: 15562 The above Prefix + Maxlength has the exact same meaning as: Prefix: 2001:67c:208c::/48 or 2001:67c:208c::/49 or 2001:067c:208c:8000::/49 or 2001:67c:208c::/50 or 2001:67c:208c:4000::/50 or 2001:67c:208c:8000::/50 or 2001:67c:208c:c000::/50 Origin AS: 15562 The confusion & an UX experiment proposal ========================================= I suspect that many people think that "xxx/48 maxlength 50" means "the /48, AND the four individual /50s" (mentally skipping over the intermediate /49s). Going back as far as 2011 [1] - the concept of "MaxLength" appeared less than straight-forward, the quest for a good 'default setting' seems a challenge. My experience at NTT taught me that encouraging customers to create IRR "route:" or "route6:" objects that *exactly* match what people intend to announce in the BGP plane, greatly simpifies things. Just register what you want to announce, nothing more, nothing less. A proposal for UX experiment: would it be beneficial to HIDE the 'maxlength' field (for some period of time) in the RPKI ROA management system hosted by RIPE NCC? If the option isn't there, it can't confuse people. Wouldn't it be better to encourage people to create ROAs that align one-to-one with BGP announcements? (keep in mind: IRR route/route6 objects don't have the notion of maxlength). Or an enhancement: a button "also create ROAs for all /24s and /48s, but not the intermediate prefix lengths". This saves people a lot of clicking if they want to prepare for maximum de-aggregation. Is MaxLength used in the wild? ============================== Only 15% of Validated ROA Payloads (VRPs) under the RIPE NCC Trust Anchor have the MaxLength field set to something other than the aggregate Prefix Length. I'm not entirely convinced that accommodating the 15% is worth the hassle of explaining what the heck MaxLength is. Removing MaxLength from the UI does not in any way impact anyone's ability to create as many ROAs as they deem fit, it just forces people to be precise! :-) Thoughts?

Code Audit Report for RPKI
by Bart Bakker 10 Dec '21

10 Dec '21

Dear colleagues, Continuing from the work we started last year on strengthening our security compliance, we have asked an external party to carry out a security audit of our RPKI code. This was an important element in preparation for open sourcing the RPKI core code, which will be done in early January 2022. We are publishing the security report for the second year in an effort to increase transparency and trust in the RPKI system. On our website [0], you will now find the code audit report written by Radically Open Security 2021 and our response to their findings. We hope you will find these reports useful, and we look forward to your feedback.
