^^^(See Facilitator Queue at tail)
Weekly meetings, every Thursday at 16:00 UTC, in #tor-meeting at OFTC
(channel is logged while meetings are in progress)
This week's Facilitator: onyinyang
== Goal of this meeting ==
Weekly check-in about the status of anti-censorship work at Tor.
Coordinate collaboration between people/teams on anti-censorship at the Tor Project and Tor community.
== Links to Useful documents ==
* Our anti-censorship roadmap:
* Roadmap:Development · Boards · Anti-censorship · GitLab
* The anti-censorship team's wiki page:
* Home · Wiki · The Tor Project / Anti-censorship / Team · GitLab
* Past meeting notes can be found at:
* The tor-project Archives
* Tickets that need reviews: from projects, we are working on:
* All needs review tickets:
* Merge requests · Anti-censorship · GitLab
* Project 158 <-- meskio working on it
* Issues · Anti-censorship · GitLab
== Announcements ==
== Discussion ==
\* Creating container mirror for anti\-cenosorship projects to deal with docker hub restriction
\* https://gitlab.torproject.org/tpo/tpa/team/-/issues/41914#note_3138851
\* https://gitlab.torproject.org/tpo/anti-censorship/pluggable-transports/snowflake/-/issues/40393#note_3138149
\* we'll create a repo in gitlab that mirrors the needed images by it's CI
\* WIP MR: Add covert\-dtls to proxy and client
\* https://gitlab.torproject.org/tpo/anti-censorship/pluggable-transports/snowflake/-/merge_requests/448
\* is a big change, shelikhoo did review it but more eyes are needed
\* cohosh will look into it
\* Reasonable PollInterval for Orbot? https://github.com/tladesignz/IPtProxy/pull/58
\* standalone proxy does 5seconds poll interval
\* orbot was doing the same but being mobile it might be better to be slower
\* 120sec sounds like a good number seeing that there are already a lot of proxies
== Actions ==
== Interesting links ==
\* call out for webtunnel bridges for Russia:
\* https://blog.torproject.org/call-for-webtunnel-bridges/
\* Deprecation BridgeDB blogpost:
\* https://blog.torproject.org/making-connections-from-bridgedb-to-rdsys/
== Reading group ==
\* We will discuss "" on
\*
\* Questions to ask and goals to have:
\* What aspects of the paper are questionable?
\* Are there immediate actions we can take based on this work?
\* Are there long\-term actions we can take based on this work?
\* Is there future work that we want to call out in hopes that others will pick it up?

onyinyang: 2024-12-05
Last week(s):
- working on refactor of Lox (library) protocols to improve issuing efficiency as described in: https://eprint.iacr.org/2024/1552.pdf
- finished aside from check-blockage and trust promotion protocols which may not be convertable
- Released lox-library and lox-utils 0.2.0 for browser integration
- stablized some dependencies for integration into firefox with XPCOM
- created bridgeauth feature to separate client/server lox functionality
- Improved pipeline for lox workspace
- Added lox-context db cleanup
Next week:
- Fix up Troll-patrol MR
- Deploy test distributor
- update lox protocols to return duplicate responses for an already seen request
- Continue work on implementing issuer efficiency for check-blockage and trust-promotion protocols
- Work on outstanding milestone issues:
in particular: Increase the acceptable time for bridgeline failure (#69) · Issues · The Tor Project / Anti-censorship / lox · GitLab
- key rotation automation
Later:
pending decision on abandoning lox wasm in favour of some kind of FFI? https://gitlab.torproject.org/tpo/applications/tor-browser/-/issues/43096):
\- add pref to handle timing for pubkey checks in Tor browser
\- add trusted invitation logic to tor browser integration:
- improve metrics collection/think about how to show Lox is working/valuable
- sketch out Lox blog post/usage notes for forum
\(long term things were discussed at the meeting\!\):
\- brainstorming grouping strategies for Lox buckets \(of bridges\) and gathering context on how types of bridges are distributed/use in practice
Question: What makes a bridge usable for a given user, and how can we encode that to best ensure we're getting the most appropriate resources to people?
1\. Are there some obvious grouping strategies that we can already consider?
e\.g\., by PT, by bandwidth \(lower bandwidth bridges sacrificed to open\-invitation buckets?\), by locale \(to be matched with a requesting user's geoip or something?\)
2\. Does it make sense to group 3 bridges/bucket, so trusted users have access to 3 bridges \(and untrusted users have access to 1\)? More? Less?
