Hey everyone! Here are our meeting logs: http://meetbot.debian.net/tor-meeting/2022/tor-meeting.2022-09-22-15.58.html And our meeting pad: Anti-censorship work meeting pad -------------------------------- Next meeting: Thursday Sept 29 16:00 UTC Weekly meetings, every Thursday at 16:00 UTC, in #tor-meeting at OFTC (channel is logged while meetings are in progress) == 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 Tor. == Links to Useful documents == * Our anti-censorship roadmap:* Roadmap: https://gitlab.torproject.org/groups/tpo/anti-censorship/-/boards
* The anti-censorship team's wiki page:* https://gitlab.torproject.org/tpo/anti-censorship/team/-/wikis/home
* Past meeting notes can be found at: * https://lists.torproject.org/pipermail/tor-project/ * Tickets that need reviews: from sponsors we are working on: * All needs review tickets:* https://gitlab.torproject.org/groups/tpo/anti-censorship/-/merge_requests?scope=all&utf8=%E2%9C%93&state=opened&assignee_id=None
* Sponsor 28* must-do tickets: https://gitlab.torproject.org/groups/tpo/-/milestones/10 * possible tickets: https://gitlab.torproject.org/groups/tpo/-/issues?scope=all&utf8=%E2%9C%93&state=opened&label_name%5b%5d=Sponsor%2028&milestone_title=None
* Sponsor 96 * https://gitlab.torproject.org/groups/tpo/-/milestones/24 == Announcements == * == Discussion == * snowflake-01 bridge running into resource limitations * need to increase number of tor instances at least* https://gitlab.torproject.org/tpo/anti-censorship/pluggable-transports/snowflake/-/issues/40173 * also running into other resource limitations: CPU cannot be increased much more, and snowflake-server is periodically restarting due to a lack of memory * the snowflake-01 bridge is one of the largest relays in the network. compare to https://metrics.torproject.org/rs.html#toprelays. snowflake-01 had 72 MB/s average throughout August 2022, so it is right up there with the top relays. * tried in the past to decrease resource requirements of snowflake-server, without much results https://gitlab.torproject.org/tpo/anti-censorship/pluggable-transports/snowflake/-/issues/40086 * will at least recompile snowflake-server with a recent golang compiler when redeploying this time * what about making snowflake the default recommendation in Iran? https://gitlab.torproject.org/tpo/anti-censorship/rdsys/-/issues/119 * possible, but there are still concerns about load at the bridge * how close are we to being able to start using the snowflake-02 bridge? https://gitlab.torproject.org/tpo/anti-censorship/pluggable-transports/snowflake/-/issues/28651 https://gitlab.torproject.org/tpo/anti-censorship/pluggable-transports/snowflake/-/issues/40129 * will be necessary soon, because snowflake-01 cannot scale forever * the limiting factor at this point is the number of proxies that multi-bridge aware
* only about 30% of available proxies are multi-bridge aware * is 30% sufficient for current client demand?* most proxies are browser add-ons, which should automatically update * shelikhoo will investigate why such a large fraction of proxies have not updated * does connection assist help with getting clients to use a second bridge, or does it require a new Tor Browser release? * connection assist likely does not help, since old clients will not know how to send the bridge fingerprint they want to the broker -- if they use the -02 fingerprint but do not tell the broker that, the broker will connect them with the -01 bridge, and the connection will fail
* Gettor Telegram Bot down. Fix deployed * increase in user result in hit Telegram API Limit * Fix deployed to restore it to working state * Community Team developed a guide for IR circumvention* https://forum.torproject.net/t/iran-circumventing-censorship-with-tor/4590
* currently awaiting translation == Actions == == Interesting links == == 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?

Itchy Onion: 2022-09-22 Last week:- several attempts (adjusting various timeout, trying the obfs approach of creating a smux session, and reserching other options) to fix the RACE unclosed TCP connection issue (https://gitlab.torproject.org/tpo/anti-censorship/pluggable-transports/snowflake/-/issues/40160).
This week:- update snowflake plugin API to RACE 2.3.x (https://gitlab.torproject.org/tpo/anti-censorship/team/-/issues/58) - I learned yesterday that there is a working build of snowflake 2.2.x from Eliana. I have requested the code and am still waiting for it. Will ask again in my 1-1 meeting with Eliana later today
