Tor dev meeting =============== * Many anti-censorship team members attended Tor's developer meeting. Here are the meeting notes of all censorship-related sessions: <https://trac.torproject.org/projects/tor/wiki/org/teams/AntiCensorshipTeam#Tormeetingnotes> * We talked to OONI and asked if they could measure the availability of STUN servers for us. This would help with learning where snowflake is blocked: <https://github.com/ooni/probe/issues/875> * Started working on a "censorship table" that encodes what's necessary to get Tor to work in a given country (or autonomous system). Ultimately, Tor Browser should to use this table to help its users connect to the network while minimising user interaction: <https://bugs.torproject.org/28531> * Created a ticket for an easy-to-use Tor bridge meta Debian package: <https://bugs.torproject.org/31153> We hope to be done with this before our "set up new bridges" outreach campaign. Snowflake ========= * Deployed a proxy-go instance that uses the pion WebRTC library: <https://bugs.torproject.org/28942> We're evaluating if pion could replace libwebrtc for us. * Started working on the web extension "infinite loop bug" that currently affects Firefox: <https://bugs.torproject.org/31100> * Google's "Safe" Browsing system blocked snowflake's infrastructure domains *.bamsoftware.com. This is a false positive that was apparently caused by an educational article: <https://www.bamsoftware.com/hacks/zipbomb/> We migrated to a new domain: <https://bugs.torproject.org/31250#comment:13> * Fixed <https://bugs.torproject.org/27385> (<https://snowflake.torproject.org/embed> is confusing). * Started adding localisation to user-facing snowflake components: <https://bugs.torproject.org/30310> * Progress on easier-to-see snowflake icons in Firefox's dark mode: <https://bugs.torproject.org/31170> * Revised snowflake's project page: <https://snowflake.torproject.org> Bridge operators ================ * Worked with bridge operators who had troubles getting obfs4 to work. Pluggable transports ==================== * Started fixing a number of issues in our PT 1.0 spec. Here is our canonical list of issues: <https://bugs.torproject.org/29285#comment:5> Hopefully, there will be a way to merge these fixes with the PT 2.0 spec. Here's the in-progress feature branch: <https://dip.torproject.org/phw/torspec/tree/feature/29285> * Added in-progress wiki page on retiring pluggable transports: <https://trac.torproject.org/projects/tor/wiki/doc/PluggableTransports/GuidelinesForRetiringPTs> BridgeDB ======== * Deployed in-progress BridgeDB metrics feature branch which will give us insight into how BridgeDB is used: <https://bugs.torproject.org/9316> Found and fixed numerous bugs and eventually published first insights into BridgeDB metrics: <https://lists.torproject.org/pipermail/tor-dev/2019-July/013953.html> * Resurrected an old ticket to expose BridgeDB's assignments file again. This would allow bridge operators to see what bucket their bridge is in: <https://bugs.torproject.org/29480> Miscellaneous ============= * Reviewed a Tor Research Safety Board submission. * Wrote a summary of the NDSS'17 paper "Dissecting Tor Bridges": <https://lists.torproject.org/pipermail/anti-censorship-team/2019-July/000023.html> * Filed ticket to have a single Tor instance support, say, more than one obfs4 instance: <https://bugs.torproject.org/31228> * Summarised the MASQUE circumvention protocol: <https://lists.torproject.org/pipermail/anti-censorship-team/2019-July/000027.html> * Cecylia attended the Citizen Lab's Summer Institute 2019 and PETS 2019. * Philipp will attend the OTF summit in Taiwan, and probably also potential pre and post events.
