RFO for RIPE NCC RPKI outage 16 February 2022
by Ties de Kock 17 Feb '22

17 Feb '22

Dear colleagues, This afternoon, between 13:00 UTC and 14:10 UTC rrdp.ripe.net was unavailable. During this period, a significant fraction of relying party instances attempting to fall back to rsync://rpki.ripe.net could not retrieve objects due to capacity constraints. At approximately 13:00 UTC, the RPKI team attempted to move the DNS records for rrdp.ripe.net from out of the ripe.net zone file into a separate include file. We did this change to prepare for implementing an automated failover between the CDNs. This resulted in an outage in the RRDP service, which was caused by an issue in the ripe.net zone file in the DNS zone. The file contains several $ORIGIN directives, but they are not reset properly when a block ends. The consequence is that later relative names in the zone file accidentally get the incorrect origin applied to them, and it is easy to miss this if the $ORIGIN directive appears much earlier in the file. To prevent such DNS issues in the future, all the blocks will be moved out of the main zone file into separate include files, because $ORIGIN directives in them do not persist beyond the end of the file. Also, earlier today, we hit an issue that our monitoring was broken due to a change in the prometheus configuration file. This reduced our visibility into the outage and meant no alerts were sent until this recovered. A third contributing factor was that a secondary monitoring system monitoring the RPKI prometheus infrastructure did not alert due to the web interface returning an HTTP 200 despite the broken configuration. A final factor was that the capacity of rsync://rpki.ripe.net is limited. Only part of the relying party instances that attempted to fall back could update from rsync. This prevented relying party instances from retrieving new objects. Full timeline: * 07:04 UTC: broken alert configuration committed * 08:46 UTC: broken alert configuration applied, breaking monitoring. * 13:02 UTC: DNS change (effectively removing rrdp.ripe.net from zone) applied * 13:44 UTC: alert configuration reverted * 14:10 UTC: DNS configuration recovered * 14:25 UTC: rsync connection rate back at baseline level During the period where rrdp.ripe.net was not available, many relying party instances started falling back to rsync. On partial data available, we observed a median rsync connection duration of 300 seconds, and 99th percentile of 1660 seconds, with ~55% of rsync connections disconnecting with an error code. Based on this preliminary data we conclude that this is indicative of underlying IO limitation in our NFS setup. We will further investigate this. During the period of outage, our rsync servers returned 5043 “max connection reached” errors to 2307 unique IP addresses. We have applied one mitigation (linting of alert configuration). We are also working on improving our external monitoring without a dependency on on-premise infrastructure. Kind regards, Ties

I hope other validators take inspiration from this, similar to how we (OpenBSD) took inspiration from the Dragon Labs implementation. Your work lives on and on, hat tip to you Rob! :-) RRDP doesn't convey things like file modification dates that rsync > needs to perform an efficient incremental transfer, so the first rsync > pass is still going to be expensive. > > Not obvious to me that there's any good way to optimize this. YMMV. > Ties once pointed me at the GPL rsync “-c” (checksum) option, which makes transfers more focussed on content rather than filesystem attributes. From my (openrsync) this is still work to be done. I see a path :-) Kind regards, Job

rsync://rpki.ripe.net rsyncd limits set too low?
by Job Snijders 17 Feb '22

17 Feb '22

Hi all, I noticed the RIPE NCC RRDP service (https://rrdp.ripe.net/) became unreachable at 2022-02-16 13:34:10 UTC+0 (and still is down). This RRDP outage event should not pose an issue for most RPKI validators, because most RPKI cache implementations (which follow best practises) will attempt to try to synchronize via RSYNC, in case RRDP is unavailable. However, it seems RIPE NCC adjusted the default rsyncd settings and lowered the concurrent connection count from 200 (which already is too low for RPKI Repository Servers) to 150? $ rsync --no-motd -rt rsync://rpki.ripe.net/repository/ @ERROR: max connections (150) reached -- try again later rsync error: error starting client-server protocol (code 5) at main.c(1666) [Receiver=3.1.2] I'm not familiar with the RIPE RPKI RSYNC service architecture, so the above error could be misleading: perhaps there is a loadbalancer distributing TCP sessions across multiple backends, each backend configured to serve up to 150 clients? Or perhaps there is a single rsyncd instance (in which case 150 definitely is too low). Is the RIPE NCC RPKI RSYNC service underprovisioned? If yes, why? Kind regards, Job

Open-sourcing of the RIPE NCC’s RPKI core software
by Bart Bakker 17 Feb '22

17 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 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
