Hi everyone, Here's what the anti-censorship team has been up to in October: Snowflake ========= * Continued work on a sequencing and reliability layer for snowflake: <https://bugs.torproject.org/29206> * Localised the snowflake.torproject.org website and implemented a language switcher: <https://bugs.torproject.org/31384> * Added an automatic packaging script for the snowflake web extension: <https://bugs.torproject.org/31253> * Fixed a bug in the web extension hat was keeping open UDP sockets: <https://bugs.torproject.org/31285> * Continued to investigate and monitor snowflake network health. * Snowflake web extension localisation updates. * Refactored the web extension code to allow for multiplexing of multiple clients through a single browser proxy: <https://bugs.torproject.org/31310> * Reduced unnecessary error messages in snowflake logs. BridgeDB ======== * Finished updating BridgeDB's requirements and created a process for keeping requirements up-to-date in the future: <https://bugs.torproject.org/29484> <https://gitweb.torproject.org/bridgedb.git/tree/doc/HACKING.md#n36> * Finished BridgeDB's language switcher: <https://bugs.torproject.org/26543> You can find it in the top right corner over at <https://bridges.torproject.org> * Accidentally fixed another UI issue while implementing the language switcher: <https://bugs.torproject.org/19839> * Debugged and fixed BridgeDB's email autoresponder. It broke after the underlying operating system was updated to the latest Debian stable: <https://bugs.torproject.org/32105> * Finished specification of BridgeDB's metrics format: <https://bugs.torproject.org/31780> * Started ripping out PGP support in BridgeDB's email autoresponder: <https://bugs.torproject.org/17548> BridgeDB's PGP keys have expired many years ago and the feature does not seem popular enough to warrant the (likely non-trivial) effort of resurrecting it. * Implemented a parser for BridgeDB metrics and used it to create a bunch of visualisations: <https://bugs.torproject.org/32135> * Fixed a bug that resulted in BridgeDB not logging vanilla bridges in its metrics: <https://bugs.torproject.org/32203> * Took a look at BridgeDB's broken email localisation: <https://bugs.torproject.org/15404> This is another broken feature that may not be worth the effort it takes to fix it. * Requested and installed new translations. Thanks to all volunteers who helped translate BridgeDB! GetTor ====== * Moved to a new VM. * More work towards bringing the Twitter responder back to life. Miscellaneous ============= * Implemented a prototype of bridgestrap, a service that takes as input a bridge line and tells you if it can bootstrap a tor connection over the given bridge: <https://bugs.torproject.org/31874> * Filed a ticket to discuss the future of website mirrors: <https://bugs.torproject.org/31990> * Wrapped up our "set up new obfs4 bridges" campaign: <https://bugs.torproject.org/30777> Our volunteers helped set up approximately 100 new bridges! * Started distributing some of our new high-capacity private obfs4 bridges. Also created a YAML file to coordinate who got what bridges. Obfs4 ===== * Made good progress on improving our obfs4 bridge Docker image: <https://bugs.torproject.org/31834> * Finished a prototype of sharknado, a backwards-compatible obfs4 improvement: <https://bugs.torproject.org/30716#comment:16> * Created a wiki page that documents the process for supplying an NGO with private obfs4 bridges: <https://trac.torproject.org/projects/tor/wiki/org/teams/AntiCensorshipTeam/NGOBridgeSupport> * Conducted a probe test of a subset of our newly created obfs4 bridges from the bridge campaign in September. Found that all of the new bridges we tested seem to be blocked already in China: <https://trac.torproject.org/projects/tor/attachment/ticket/31701/obfs4-reachability-2019-10-03.pdf> Tor Browser =========== * Upgraded goptlib to v1.1.0, fixing an error condition that would arise when using a pluggable transport with a non-working proxy: <https://bugs.torproject.org/32076> <https://bugs.torproject.org/32056>
