PieroV's monthly status report
by Pier Angelo Vendrame 01 Mar '22

01 Mar '22

Hi everyone! Here is my status report for February 2022. This month I continued working on the Tor Browser connection preferences. I was also assigned the related changes on the about:torconnect page. All the updates are on the merge request (tor-browser!254 <https://gitlab.torproject.org/tpo/applications/tor-browser/-/merge_requests…>). As you can see, we are taking care of every detail 💫! And we will continue working on it also in March. Another change I worked on is the HTTPS-only mode (tor-browser#19850 <https://gitlab.torproject.org/tpo/applications/tor-browser/-/issues/19850>). With it, HTTPS-Everywhere will not be needed anymore. However, we want to keep .tor.onion aliases working. Therefore, recently I worked on a replacement for this extension (tor-browser#40458 <https://gitlab.torproject.org/tpo/applications/tor-browser/-/issues/40458>). I will continue working on it in March. Finally, I reviewed some merge requests (the 91.6 rebases and torbutton!72 <https://gitlab.torproject.org/tpo/applications/torbutton/-/merge_requests/72> to show IPv6 addresses on circuit display) and worked a little bit on Tor Browser tests. And that is all for February 🙂. Thanks, Pier

new BridgeDB version using rdsys
by meskio 28 Feb '22

28 Feb '22

Hello, I have just deployed a new version of BridgeDB[0]. Now BridgeDB uses rdsys[0] as backend so it has changed how bridges are managed internally, but all the user facing pieces are (almost) the same. The distributors (email, https[1] and moat) hasn't changed and should work as before. If you are a bridge user you should not see any difference. The bridges you are already using should stay working and requesting new bridges should work as before. The move to rdsys implies that all the bridges might have changed their distribution mechanism. If you are bridge operator you might see your bridge having a different distributor mechanism in the coming hours, if you had configured your bridge with the "BridgeDistribution" option your distribution mechanism should not change and stay on what you configured. There are more few more distribution mechanisms now, this is the full list: * https. The web interface of bridgedb[0]. * moat. The API used by Tor Browser to request bridges directly from the settings. * email. Bridges distributed by bridges(a)torproject.org. * telegram. Bridges that will be distributed by the telegram bot @GetBridgesBot. * settings. A new API used to autoconfigure the circumvention mechanism depending on your geolocation. * reserved. Bridges reserved for experiments or future needs. People with bridges assigned to telegram and settings will not see much usage of their bridges yet, as those are projects we are working on but will be soon in use. If you notice any problems with the bridge distribution don't hesitate to open an issue[2] or contact me.

by David Goulet 23 Feb '22

23 Feb '22

Greetings, Network team will be releasing on Friday a new alpha (0.4.7.4-alpha) but this one is very special, it is the first alpha with the gigantic congestion control work in it. https://gitlab.torproject.org/tpo/core/tor/-/issues/40405 https://gitlab.torproject.org/tpo/core/torspec/-/blob/main/proposals/324-rt… There are also couple important fixes for relay operators running alphas and so we will recommend to upgrade. With this alpha, we hope to get to a release candidate very soon and then onto the long awaited 0.4.7 stable in around 2-3 months. Upcoming versions: - 0.4.7.4-alpha @network-team: It is _now_ a good time to start reviewing changes/ files: https://gitlab.torproject.org/tpo/core/tor/-/tree/main/changes Last, we've asked the dirauth to recommend these versions few minutes ago. Cheers! David -- hn/Y6tIdc7o83Kubm4tb7kwGg3cVfoop1AQ3QAX8UkA=

"As the representative to public key transform should be identical, this change is fully-backward compatible" It could be that something about the altered (fixed) mathematical transform of Elligator2 is responsible for the handshake failures. Posts about Elligator2 and the cofactor distinguishability bug: https://loup-vaillant.fr/articles/implementing-elligator https://loup-vaillant.fr/tutorials/cofactor https://www.reddit.com/r/crypto/comments/fd9t3m/elligator_with_x25519_is_br… Aaron Johnson has looked into it, and says (according to immediate memory) that the Elligator2-encoded public keys of past versions of obfs4proxy are distinguishable from random in 7/8 cases. When both side have not upgraded, it is 63/64 cases. Or something along those lines. Roger will put us in touch with Aaron to understand the encoding bug and whether it could be leading to the connection failures. Shall we roll back the obfs4proxy version in Tor Browser until we figure it out? It seems to be a small number of users who are bothered enough by the log messages to post on #40804 and on the forum https://forum.torproject.net/t/bridges-work-but-with-error-messages-in-log-… No rollback for now. We need to test a 0.0.12-to-0.0.12 connection, to see whether upgrading the server solves the connection failures. If it does, then (separately from fixing the problem in the client) we can push for server operators to upgrade. obfs4proxy-0.0.13 is already in Debian sid, it will take some time to work its way into testing and backports A non-upgraded server is detectable (with 7/8 probability) at the client. We could have the client log a message when that occurs, so the user can choose to use a different bridge, or encourage the bridge operator to upgrade. Tails's test suite caught the connection errors: https://gitlab.torproject.org/tpo/applications/tor-browser/-/issues/40804#n… uTLS for broker negotiation. Should we enable by default? the fingerprints in uTLS are pretty old, is it better to use them than go TLS? we are reachinging out to psiphon to see what they thing about uTLS maintenance V2 uses a "bring your own browser" model: the proxy forwards through a browser installed on the system to get a good TLS fingerprint. meek in Tor Browser used to do something similar, using the Firefox that is part of the bundle. Later meek got support for uTLS: https://gitlab.torproject.org/tpo/anti-censorship/pluggable-transports/meek… obfs4proxy's meek_lite implementation also got uTLS support, and the Tor Browser maintainers decided to switch to that (from mainline meek with browser forwarding) so that there would be only one binary to ship: https://gitlab.torproject.org/tpo/applications/tor-browser/-/issues/29430 == Actions == == Interesting links == == Reading group == We will discuss "Weaponizing Middleboxes for TCP Reflected Amplification" on 2022-02-17 https://censorbib.nymity.ch/#Bock2021b Questions to ask and goals to have: What aspects of the paper are questionable?
