Tor dev meeting
* Many anti-censorship team members attended Tor's developer meeting.
Here are the meeting notes of all censorship-related sessions:
* 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
* 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:
* 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.
* 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:
We migrated to a new domain:
* Fixed <https://bugs.torproject.org/27385>
(<https://snowflake.torproject.org/embed> is confusing).
* Started adding localisation to user-facing snowflake components:
* Progress on easier-to-see snowflake icons in Firefox's dark mode:
* Revised snowflake's project page:
* Worked with bridge operators who had troubles getting obfs4 to work.
* Started fixing a number of issues in our PT 1.0 spec. Here is our
canonical list of issues:
Hopefully, there will be a way to merge these fixes with the PT 2.0
spec. Here's the in-progress feature branch:
* Added in-progress wiki page on retiring pluggable transports:
* Deployed in-progress BridgeDB metrics feature branch which will give
us insight into how BridgeDB is used:
Found and fixed numerous bugs and eventually published first insights
into BridgeDB metrics:
* Resurrected an old ticket to expose BridgeDB's assignments file again.
This would allow bridge operators to see what bucket their bridge is
* Reviewed a Tor Research Safety Board submission.
* Wrote a summary of the NDSS'17 paper "Dissecting Tor Bridges":
* 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:
* Cecylia attended the Citizen Lab's Summer Institute 2019 and PETS
* Philipp will attend the OTF summit in Taiwan, and probably also
potential pre and post events.
