How BGP routes can get 'stuck' in the Default-Free Zone
by Job Snijders 21 Apr '21

21 Apr '21

Dear group, I'd like to draw your attention to an excellent article on an intricate interaction between BGP and TCP which can result in 'zombie routes' in the BGP Default-Free Zone. https://blog.benjojo.co.uk/post/bgp-stuck-routes-tcp-zero-window My current running theory on the root cause of some mishaps in the global routing system is that certain BGP implementations can end up in a broken state where such systems will still generate and send out KEEPALIVE messages, but are unable to process other BGP messages (and such a system instructs all its peers to not send new data by signalling a zero TCP receive window). This is "Problem #1". "Problem #2" is that almost all BGP implementations are unable to robustly deal with systems suffering from Problem #1. Allmost all BGP implementations assume that when KEEPALIVE messages don't make it across the wire, the remote system will initiate the session tear down. But of course, if the remote system is in such a broken state that it can't issue session tear downs ... the combined system state is perpetually broken. The Security Section of https://datatracker.ietf.org/doc/html/draft-spaghetti-idr-bgp-sendholdtimer elaborates on three detrimental facets of the above situation. It is quite rare for systems to end up in the "Problem #1" state, but when it happens, all systems connected to the broken node probably are better off disconnecting from such a system than perpetually forwarding (and potentially blackholing) Internet traffic into the broken system. Kind regards, Job

Issue affecting rsync RPKI repository fetching
by Nathalie Trenaman 15 Apr '21

15 Apr '21

Dear colleagues, We have been made aware of an issue that may affect some users who use RPKI relying party (RP) software that uses rsync. Please note that by default, only rpki-client reads from rsync; the rest of the RPs prefer the RPKI Repository Delta Protocol (RRDP). The issue appears to create some inconsistency between the RPKI repository and rsync clients. In more detail, an RRDP client reads a complete state for a specific “serial” from the repository. In contrast, an rsync client syncs the state in multiple steps. First, a list of files is copied, followed by updates for files that have been copied. In an affected scenario, a certificate is added and one of the other files (the manifest) is modified after the file list has been sent. By reading the new manifest, but not copying the new file (it is not on the rsync file list), the repository copied by the rsync client contains an invalid manifest (a file is missing) and the RP software rejects it. We are planning on changing our publication infrastructure and using the same "revisions" RRDP uses for the content of the rsync repository. Rsync is an officially supported distribution protocol for RPKI repository data, and it is one of our highest priorities that the data published is atomic and consistent. We plan to release the new publication infrastructure in Q2/Q3 2021. Part of this work will mitigate these non-repeatable-reads for clients using rsync. We will update you on our progress during RIPE 82, taking place online from 17-21 May 2021. Kind regards, Nathalie Trenaman RIPE NCC

RPKI: how to migrate an entire industry from RSYNC to RRDP?
by Job Snijders 13 Apr '21

13 Apr '21

Hi all, Some might be wondering what the deal is with RSYNC and RRDP? Why it is critical to continue to support RSYNC in the mid-term? What's the industry's plan to migrate from RSYNC to RRDP? TL;DR - All RIRs need to support both RSYNC and RRDP until at least 2024. - All RRDP-capable validators need to make sure they are fully backwards compatible with RSYNC, until RIRs no longer observe RSYNC traffic. Some background: ---------------- The development of the RPKI technology stack began more than a decade ago in the IETF. From the start, RSYNC was the preferred synchronisation protocol between RPKI publication servers (such as 'rpki.ripe.net') and Relying Parties (the likes of Telia, NTT, Amazon, me, and you). RSYNC was picked for a number of reasons: it was available & easy. A core concept of the RPKI technology stack is that RPKI objects can be transported via any means: carrier pigeon (RFC 2549 ;-), USB stick, FTP, RSYNC, ... anything! This is possible because RPKI exclusively relies on 'object security', the RPKI objects themselves contain all information that is required to perform X.509-based validation. As time went by, a second approach was developed to synchronize RPs to fresh data generated by CAs. It was recognized that where RSYNC servers need to calculate the 'difference' between the client has and what the server has (right after the RSYNC client connects), such data could also be generated a-priori and stored in static files. Pre-generating such a 'journal' of all changes in a repository is considered to be far efficient than calculating it on the fly. The RRDP protocol has many appealing properties! In 2017 the RRDP protocol was published as IETF RFC as 'nice to have' synchronization protocol for the RPKI. Since then, more and more Publication Servers operators and RP software implementers worked to support the new RRDP protocol alongside the old RSYNC protocol. With two options available, how to migrate? ------------------------------------------- This Gordian Knot has two aspects: all deployed RPKI repository operators have to support RRDP, and all deployed Relying Party have to support RRDP. This means that for a succesful transition, for a moment in time, all stakeholders have to support both RSYNC and RRDP. The industry has not yet reached that point. I expect this to happen somewhere in 2023. At this moment of writing, not all Relying Party software, and not all RPKI Repository Operators support RRDP. Based on various communications in the IETF it is clear everyone is working towards implementing RRDP support. However producing a safe implementation of RRDP is not a trivial task, it takes time. As RSYNC existed first and RRDP came later, everyone should be allowed ample time to make the transition. While everyone waits for everyone to deploy RRDP capable software, the trick is to PREFER synchronizing via RRDP (and if it fails try RSYNC). Relevant Internet-Draft: https://datatracker.ietf.org/doc/draft-ietf-sidrops-prefer-rrdp/ The concept this is somewhat analogous to 'Happy Eyeballs': for a period of time many considered it advantageous for global IPv6 deployment to give IPv6 just a little bit of a head start compared to IPv4. People knew that purposefully degrading IPv4 would not motivate people to embrace IPv6. Also, preferring RRDP (and only using RSYNC in case of RRDP failure), makes life easier for RPKI Repository operators: it should be possible for them to temporarily disable the RRDP webserver and expect clients to use RSYNC instead. Knowing that clients will gracefully fall back to RSYNC lowers the barrier to deploy RRDP. Once all RP implementations have embraced the 'prefer RRDP' strategy, and those implemenations have trickled down into the hands of network operators and deployed in the field, Repository Operators will observe less and less clients connecting to the RSYNC service and more and more syncing via RRDP, to the point where it becomes self-evident publication via RSYNC can maybe even be decommissioned all together. TL;DR - general availability of software which prefers RRDP over RSYNC, combined with patience, should be sufficient of a plan to migrate! :) Current status -------------- Current versions of OpenBSD rpki-client supports RSYNC. The team is actively working to also support RRDP. The hope is to release a stable version later this year. OpenBSD supports releases for one year, thus any deprecation of RSYNC services should be post-poned at least until Spring 2023 to avoid disenfranchising existing deployments in the field. The RIPE NCC Validator RRDP implementation is broken. It is trivial for any RRDP Repository Operator to remotely crash the entire RIPE NCC validator process. Luckily the software is almost End-Of-Life and soon won't be relevant anymore. Current versions of Routinator are unable to fall back to RSYNC. However in November 2020, the team indicated they would fix this in the next release (which has yet to happen). Perhaps somewhat counterintuitive, an inability to fallback to RSYNC, makes migrating towards RRDP harder for the industry. For a peer-reviewed scientific publication on this phenomena see: https://dl.acm.org/doi/10.1145/3419394.3423622 I've not inspected how other validators behave, and we should keep in mind proprietary rsync-only validator implementations might exist this community is not aware of! How to move forward in the short term? -------------------------------------- RIPE NCC must support RSYNC as a first-class service. The RPKI via RSYNC is a LIVE production system. The global Internet routing system relies on the Trust Anchors to publish correctly. The suggestion it might take six months (from report to resolution) is too long of a waiting period for this type of issue. There are known negative interactions between inconsistent RPKI publications & BGP routing in the Default-Free Zone. This affects all Internet users. It is not possible to get hundreds of operators to migrate to RRDP overnight, but it is possible for RIPE NCC to improve RSYNC publication (while the world very slowly moves to RRDP).

RPKI Route Origin Validation on RIPE NCC Network
by Nathalie Trenaman 13 Apr '21

13 Apr '21

Dear colleagues, (My colleagues are drafting a reply on the rsync issue) Following up on my previous email and the discussion we had in this mailing last about enabling Route Origin Validation (ROV) invalid == reject on the RIPE NCC’s network, AS3333, I am happy to inform you that we will be going ahead on Monday, 19 April. I have written a RIPE Labs article with more information, which you can find at: https://labs.ripe.net/author/nathalie_nathalie/rpki-and-as3333-or-how-we-ea… Thank you very much for your contributions, discussion and support. Kind Regards, Nathalie Trenaman Routing Security Programme Manager RIPE NCC

RIPE Database requirements progress
by ripedenis＠yahoo.co.uk 08 Apr '21

08 Apr '21

Colleagues For the benefit of those who don't often check the mail archives of the RIPE Database Task Force there have been 4 meetings in February and March and the TF has just published the minutes of their most recent meeting on their mail archive which can be found here:https://www.ripe.net/ripe/mail/archives/ripe-db-requirements-tf/ Their latest draft requirements document can be found here:https://www.ripe.net/participate/ripe/tf/rdb-requirements-tf/the-ripe-… There are quite a number of recommendations made regarding the IRR and routing data in the RIPE Database. It would be helpful if more people would read this document and comment or discuss publicly on this WG mailing list any issues regarding the TF draft document before they publish their final version of the requirements. They also plan to hold a BOF sometime in May where you can make comments. cheersdenisco-chair DB-WG
