Notes from TPA 2025 roadmap review meeting
by Gabriel Filion 13 Jan '25

13 Jan '25

Hello all, The TPA team had a meeting today where we prioritized our goals mostly for Q1 of 2025 and had discussions about how to go around furthering the merger with tails, especially on the Puppet side (e.g. so that both Tor and Tails infrastructures can become managed by only one tool) Here are the notes from the meeting: --- title: 2025 Q1 Roadmap meeting --- # Roll call: who's there and emergencies - anarcat - groente - lavamind - lelutin - zen # Dashboard review Normal per-user check-in: - <https://gitlab.torproject.org/groups/tpo/-/boards?scope=all&utf8=%E2%9C%93&…> - <https://gitlab.torproject.org/groups/tpo/-/boards?scope=all&utf8=%E2%9C%93&…> - <https://gitlab.torproject.org/groups/tpo/-/boards?scope=all&utf8=%E2%9C%93&…> - <https://gitlab.torproject.org/groups/tpo/-/boards?scope=all&utf8=%E2%9C%93&…> - <https://gitlab.torproject.org/groups/tpo/-/boards?scope=all&utf8=%E2%9C%93&…> General dashboards: - <https://gitlab.torproject.org/tpo/tpa/team/-/boards/117> - <https://gitlab.torproject.org/groups/tpo/web/-/boards> - <https://gitlab.torproject.org/groups/tpo/tpa/-/boards> # 2025Q1 Roadmap review Review priorities for January and the first quarter of 2025. Pick from the [2025 roadmap](https://gitlab.torproject.org/tpo/tpa/team/-/wikis/roadmap/2025). Possibilities for Q1: - [Puppet CI and improvements](https://gitlab.torproject.org/groups/tpo/tpa/-/milestones/8): GitLab MR workflow, etc - Prometheus - MinIO - web stuff: download page coordination and deployment - email stuff: eugeni retirement, puppet cleanup, lists server (endless stream of work?), re-examining open issues to see if we fixed anything - discussions about SVN? - tails merge: - password stores - security policy - rotations - Puppet: start to standardize and merge codebases, update TPA modules, standardize code layout, maybe switch to nftables on both sides? Hoping *not* for Q1: - rdsys containerization (but we need to discuss and confirm the roadmap with meskio) - network team test network (discussions about design maybe?) - upgrading to trixie # Discuss and adopt the long term Tails merge roadmap <https://gitlab.torproject.org/tpo/tpa/team/-/wikis/policy/tpa-rfc-73-tails-…> In [the last discussion about the tails merge roadmap](https://gitlab.torproject.org/tpo/tpa/team/-/wikis/meeting/2024-11…, we have: > postpone[d] the "what happens when" discussion. We also identified that most services above "low complexity" will require their own discussions (e.g. "how do we manage the Puppet control repo", "how do we merge weblate") that will happen later. So we try to schedule those items across the 5 years. And we can also discuss specific roadmap items to see if we can settle some ideas already. Or we postpone all of this to the 2026 roadmap. Results of the discussion: We won't have time to discuss all of these, so maybe we want to sort based on priority, and pick one or two to go more in depth. Output should be notes to add to tpa-rfc-73 and a reviewed 2025 roadmap, then we can call this done for the time being and come back closer to end of 2025. We will adopt TPA-RFC-73 as a general guide / rough plan and review as we go. Here are all the medium and high complexity items we might want to discuss: ## 2025 See also the milestone: %"TPA-RFC-73: Tails merge (2025)" - [Security Policy](#security-policy) (merge, discussion delegated to anarcat) - [Shifts](#shifts) (merge, brainstorm a plan) - Puppet merge (merge, brainstorm of a plan): - deploy dynamic environments (in progress) - we can't use environments to retire one of the two puppet servers, because of exported resources - Upgrade and converge Puppet modules - lots of default stuff get deployed by TPA when you hook up a server, we could try turning everything off by default, move the defaults to a profile - maybe prioritize things, prioritize A/B/C, example: - A: "noop TPA": Kill switch on both sides, merged ENC, g10k, review exported resources, have one codebase but 2 implementations, LDAP integration vs tails? - B: "priority merge start": one codebase, but different implementations. start merging services piecemeal, e.g. two backup systems, but single monitoring system? - C: lower priority services (e.g. backusp?) - D: etc - Implement commit signing - [EYAML](#eyaml) (2029, keep?) (migrate to trocla?) - A plan for [Authentication](#authentication) (postpone discussion to later in 2025) - [LimeSuvey](#limesurvey) (merge) (just migrate from tails to TPA?) - [Monitoring](#monitoring) (migrate, brainstorm a plan) We mostly talked about Puppet. groente and zen are going to start drafting up a plan for Puppet! ## 2026 - Basic system functionality: - [Backups](#backups) (migrate) (migrate to bacula or test borg on backup-storage-01?) - [Authentication](#authentication) (merge) (to be discussed in 2025) - [DNS](#dns) (migrate) (migrate to PowerDNS?) - [Firewall](#firewall) (migrate) (migrate to nftables) - [TLS](#tls) (migrate, brainstorm a plan) - [Web servers](#web-servers) (merge, no discussion required, part of the Puppet merge) - [Mailman](#mailman) (merge, just migrate to lists-01?) - [XMPP](#xmpp) / [XMPP bot](#xmpp-bot) (migrate, delegate to tails, postponed: does Tails have plans to ditch XMPP?) ## 2027 - [APT repository](#apt-repository) (keep, nothing to discuss?) - [APT snapshots](#apt-snapshots) (keep) - [MTA](#mta) (merge) (brainstorm a plan) - [Mirror pool](#mirror-pool) (migrate, brainstorm) - [GitLab](#gitlab) (merge) - close the tails/sysadmin gitlab project? - brainstorm of a plan for the rest? - [Gitolite](#gitolite) (migrate, retire Tails' Gitolite and puppetize TPA's?) ## 2028 - [Weblate](#weblate) (news from emmapeel?) ## 2029 - [Jenkins](#jenkins) (migrate, brainstorm a plan or date?) - [VPN](#vpn) # Metrics of the month - hosts in Puppet: 91, LDAP: 90, Prometheus exporters: 512 - number of Apache servers monitored: 33, hits per second: 618 - number of self-hosted nameservers: 6, mail servers: 11 - pending upgrades: 5, reboots: 90 - average load: 0.56, memory available: 3.11 TiB/4.99 TiB, running processes: 169 - disk free/total: 60.95 TiB/142.02 TiB - bytes sent: 434.13 MB/s, received: 282.53 MB/s - planned bookworm upgrades completion date: was completed in 2024-12! - [GitLab tickets][]: 257 tickets including... - open: 0 - icebox: 160 - roadmap::future: 48 - needs information: 2 - backlog: 21 - next: 6 - doing: 12 - needs review: 8 - (closed: 3867) [Gitlab tickets]: https://gitlab.torproject.org/tpo/tpa/team/-/boards Upgrade prediction graph lives at <https://gitlab.torproject.org/tpo/tpa/team/-/wikis/howto/upgrades/bookworm/> Now also available as the main Grafana dashboard.

cohosh's monthly status report, December 2024
by Cecylia Bocovich 07 Jan '25

07 Jan '25

Hi! This is my status report for contract work done in December 2024. # Snowflake Last month I updated our builtin and suggested Snowflake bridge lines to remove old, nonfunctional STUN servers and add new ones that would ideally present significant trade-offs for censors that would try to block them. https://gitlab.torproject.org/tpo/anti-censorship/pluggable-transports/snow… https://gitlab.torproject.org/tpo/anti-censorship/pluggable-transports/snow… https://gitlab.torproject.org/tpo/anti-censorship/rdsys-admin/-/merge_reque… https://gitlab.torproject.org/tpo/applications/tor-browser-build/-/merge_re… To help us get into a habit of doing this more often, I wrote an update script that can be run as a part of the newly documented Snowflake Release Process. https://gitlab.torproject.org/cohosh/stun-torrc-check https://gitlab.torproject.org/tpo/anti-censorship/pluggable-transports/snow… My main focus of work on Snowflake at the moment is to improve the metrics we collect at the Snowflake broker for the purpose of detecting and learning about issues or circumvention events. To this end I did some planning and opened several issues for specific improvements that I will work on this month. https://gitlab.torproject.org/tpo/anti-censorship/pluggable-transports/snow… https://gitlab.torproject.org/tpo/anti-censorship/pluggable-transports/snow… https://gitlab.torproject.org/tpo/anti-censorship/pluggable-transports/snow… Then there were the usual reviews and project maintenance tasks. # meek In anticipation of the Azure edge shutdown this month, we've now migrated all of our domain fronted services off of Microsoft Azure. We updated our builtin bridge line to use CDN77 https://gitlab.torproject.org/tpo/anti-censorship/team/-/issues/155 https://gitlab.torproject.org/tpo/applications/tor-browser-build/-/merge_re…

intrigeri's report, December 2024
by intrigeri 06 Jan '25

06 Jan '25

Hi, I was on vacation during the last 1.5 week of the year, hence this slim report. User-visible ============ I reviewed and supported the work of my team-mates on a number of high priority user-visible improvements. User-invisible ============== Apart of the usual amount of KTLO work: - Migrated our Upgrader's signature verification from GnuPG to Sequoia SOP - Fixed a few security vulnerabilities identified by an ongoing security audit. Team lead ========= I've kicked off the second year of our ongoing grant (Project 165). I've kept working, together with a number of other Tor folks from my team and other teams, on a large grant proposal. This was the opportunity for me to discover the workflows and tooling used by Tor in this area, and gain some familiarity with it. We've booked time in January, with our team & sajolida, to work on our priorities for 2025. We also booked time to do a team retrospective. Accounting ========== We've kept making slow but steady progress on transitioning away from the former Tails fiscal sponsorship arrangements into Tails' new nest, the Tor project. Cheers, -- intrigeri

Hi! Below is my December’24 report! In December, I resolved 1679 (↑110) tickets: * On Telegram (@TorProjectSupportBot) - 1459 (↑108); * On RT (frontdesk@tpo) - 219 (↑4); * On WhatsApp (+447421000612) - 1 (↓2); * and on Signal (+17787431312) - 0 (0). My main focus in December (and always)wasto provide support for Russian-speaking users in bypassing censorship. I help users to resolve any issues they are facing with Tor Browser and collect their feedback on what worked for them and what didn't. I also took part in Tor Forum moderation, took part in Relay OperatorsMeetup, and worked reviewing Google Play Store users reviews.

PieroV's Monthly Status Report, December 2024
by Pier Angelo Vendrame 02 Jan '25

02 Jan '25

Hi everyone! Here is my status report for December 2024. This month, I finally had time for some overdue tasks that took me a long time. I started with the review of our patch set, particularly the Android part. We had some residues from the Tor integration migration and the last ESR rebase [0]. Also, some patches grew too much over time, so I split them. The resulting changes [1] were not a lot, but they were enough for a merge request. We will have to come back to this in the future. Then, I could work on fingerprinting. I finalized the patch to switch from the font "whitelist" to custom font visibility rules, matching Firefox [2]. After that, I started uplifting some of our letterboxing patches. The first ones were merged two years ago, and we want to have them in Firefox by ESR140. Also, regarding fingerprinting, I checked whether a leak of system accent color was possible [3], and set a preference as a defense in depth. During the month, I also helped to formalize the process for the rebases across all the RR versions [4][5] and attended some meetings about planning and grant proposals. Best, Pier [0] https://gitlab.torproject.org/tpo/applications/tor-browser/-/issues/43024 [1] https://gitlab.torproject.org/tpo/applications/tor-browser/-/merge_requests… [2] https://gitlab.torproject.org/tpo/applications/tor-browser/-/issues/43322 [3] https://gitlab.torproject.org/tpo/applications/tor-browser/-/issues/43366 [4] https://gitlab.torproject.org/tpo/applications/tor-browser/-/issues/43298 [5] https://gitlab.torproject.org/tpo/applications/tor-browser/-/merge_requests…
