Nina’s Monthly Status Report: May 2024
by Nina 05 Jun '24

05 Jun '24

Hi! Below is my May’24 report! In May, I resolved 790 tickets: * On Telegram (@TorProjectSupportBot) - 539 * On RT (frontdesk@tpo) - 242 * On WhatsApp (+447421000612) - 9 * and on Signal (+17787431312) - 0 The focus of my work remains the same - I help Russian-speaking users of Tor Browser to install the browser and bypass internet censorship. In May we got a lot of questions from iOS and macOS users from Russiaand more specificallywhichsoftware they should install and where they should get it. Also, I help with troubleshooting and keep an eye on issues and bugs to report themto Tor developers. There are several bugs/issues I reported in May: * Built-in bridges andsomebridges obtained by email do not work in Russia[1] * Error in Tor Browser "Unable to start Tor:java.io.lo" [2] * BridgeDB does not give ipv6 bridge [3] * BridgeDB gives one and only bridge [4] In May I also took part in theCommunity Teamdocumentation sprint, whose purpose was to fill the gap in the existing documentation. So I authored and added to the several articles in the Support portaland Tor Browser user manual. * I added a section "System requirements" to the "Installation" article [5] * Added "letterboxing" term to the glossary [6] * Updated NoScriptdescription for "PLUGINS, ADD-ONS AND JAVASCRIPT" article on the support portal [7] * Wrote an article "Why are modern onion service addresses so long?"

PieroV's Monthly Status Report, May 2024
by Pier Angelo Vendrame 03 Jun '24

03 Jun '24

Hi everyone! Here is my status report for May 2024. This month, Firefox 128, which will be the base of our 14.0, reached nightly. Therefore, we're releasing 13.5 soon (with the 115.12 ESR update unless we find some last-minute problems) and then moving all our efforts to the ESR transition. So, in the past month, I partially worked on finishing some details for the 13.5. The rest of the time, I continued uplifting our patches and rebasing our patchset on Firefox's rapid release to ease the transition. For the 13.5, I finished the work on the Mullvad Browser Windows installer I started at the end of April [0]. We wanted to make the installation UX as short as possible. Only one click: you confirm you want to install the browser, and that's it 😄️. But if you want, you can still customize the installation options. When doing so, I discovered the welcome and the finish page of NSIS installers are written with the Modern UI 2 tools you would also use for custom pages. This made the task easier and less hacky, and the final result is identical to what users are familiar with. I also started implementing a localization pipeline that will be used by Tor Browser's installer as well. Then, I worked on Android localization. When we evaluated whether we needed to enable multi-lingual GeckoView builds [1], we didn't realize they were also required by the formatting APIs [2]. So, in practice, TBA supported only formatting in en-US. Enabling multi-lingual builds solved this issue. We also noticed that region data was still leaked. Therefore, I wrote a patch to make the Accepted-Language HTTP header match exactly the tag of the active translation (when not using spoof English) [3]. As for the uplifting work, I finally managed to land a patch [4] I wrote when we were moving from 91 to 102 🎉️. In addition, with the help of Firefox devtools developers, I implemented some tests and uplifted the patch not to persist the data about custom requests done in PBM [5]. This patch was initially developed by cypherpunks1, as well as the patch to add the missing origin attributes to the reader mode [6] that I also uplifted. The patch for the placeholders of the datetime-local input [7] hasn't landed yet, but at least I found why the tests were failing, and I provided a new revision. I'm waiting for another review from upstream. For the ESR rebases, I started a branch based on 127 and the branches based on 128, even though it's still nightly. I also started writing some reviewing guides (which gave me an opportunity for additional self-reviews). I found a very nice tool called "aha" [8] that converts ANSI escape sequences to HTML. I'm using it to create HTML versions of range-diff, on top of which I'm writing reports on why I needed to adapt our patches. Finally, I did some of the usual maintenance and help for this month's releases. Cheers, Pier [0] https://gitlab.torproject.org/tpo/applications/mullvad-browser/-/issues/200 [1] https://gitlab.torproject.org/tpo/applications/tor-browser-build/-/issues/4… [2] https://gitlab.torproject.org/tpo/applications/tor-browser/-/issues/42552 [3] https://gitlab.torproject.org/tpo/applications/tor-browser/-/issues/42562 [4] https://bugzilla.mozilla.org/show_bug.cgi?id=1787790 [5] https://bugzilla.mozilla.org/show_bug.cgi?id=1892052 [6] https://bugzilla.mozilla.org/show_bug.cgi?id=1892046 [7] https://bugzilla.mozilla.org/show_bug.cgi?id=1880108 [8] https://github.com/theZiz/aha

Interview week – UX meetings cancelled
by Duncan Russell 13 May '24

13 May '24

Hi everyone, Since it’s interview week for both the Product Designer and User Research Coordinator positions we’re hiring for, and our schedules are pretty full, we’ll be skipping the UX Team meeting today. Similarly, the UX Team may not be able to attend other meetings and 1:1s like normal, as we’re prioritizing time slots that work for our candidates. Thanks for your patience! Duncan

Help with: - Something you need help with. cecylia (cohosh): 2024-05-09 Last week: - Updated dependencies for various projects - Shadow simulations - https://github.com/cohosh/ptnettools - Lox-wasm integration test fixups - Opened an issue about Lox blockage migration This week: - upload new snowflake-webext version 0.8.2 to both Firefox and Chrome web stores - make changes to Lox encrypted bridge table - https://gitlab.torproject.org/tpo/anti-censorship/lox/-/merge_requests/147 - follow up on reported SQS errors - update wasm-bindgen fork to fix some bugs and hopefully upstream changes - create a Lox test environment and instructions for the browser team - https://gitlab.torproject.org/tpo/applications/tor-browser/-/issues/42503 Needs help with: dcf: 2024-05-09 Last week: - allocated new VPS for snowflake broker https://gitlab.torproject.org/tpo/anti-censorship/pluggable-transports/snow… - archived snowflake-webext 0.8.1 https://archive.org/details/snowflake-webextension-0.8.1 - posted questions about periodic(?) changes in the estimated number of users of the snowflake-01 bridge https://gitlab.torproject.org/tpo/anti-censorship/pluggable-transports/snow… Next week: - open issue to have snowflake-client log whenever KCPInErrors is nonzero https://gitlab.torproject.org/tpo/anti-censorship/pluggable-transports/snow… - parent: https://gitlab.torproject.org/tpo/anti-censorship/pluggable-transports/snow… - open issue to disable /debug endpoint on snowflake broker - move snowflake-02 to new VM Help with: meskio: 2023-05-09 Last week: - test email distributor in rdsys (rdsys#186) - extract safelog and prometheus ronded metrics from snowflake into ptutil (snowflake#40354) - look into renovate errors in rdsys, but still not clue (rdsys!305) - update and merge the bridge distribution documentation in rdsys (rdsys!295) Next week: - improve privacy on rdsys metrics reusing snowflake techniques (rdsys#203) - produce the same metrics of BridgeDB in rdsys (rdsys#188) Shelikhoo: 2024-05-09 Last Week: - [Merge Request Waiting] Add Container Image Mirroring from Tor Gitlab to Docker Hub(https://gitlab.torproject.org/tpo/anti-censorship/pluggable-transports/… - [Merge Request Merged] Fix ipv6 connectivity with restricted address support(https://gitlab.torproject.org/tpo/anti-censorship/pluggable-transpo… - [Issue] Design a new Constructor Design for Snowflake (https://gitlab.torproject.org/tpo/anti-censorship/pluggable-transports/snow…) - [Dev] Snowflake Performance Improvement - Upgrade snowflake broker machine from Debian 10 https://gitlab.torproject.org/tpo/anti-censorship/pluggable-transports/snow… - Merge request reviews - Merge request reviews Next Week/TODO: - Revise Snowflake Performance Improvement MR(cont.) - Merge request reviews onyinyang: 2023-05-02 Last week(s): - Responding to pre-existing MR reviews and other notifications/questions in gitlab This week: - attempt hyper upgrade and tokio upgrade Probably next week and beyond: - preparing for upcoming panel (maybe) - implement some preliminary user feedback mechanism to identify bridge blocking based on Vecna's work - improve metrics collection/think about how to show Lox is working/valuable - sketch out Lox blog post/usage notes for forum (long term things were discussed at the meeting!): https://pad.riseup.net/p/tor-ac-community-azaleas-room-keep - brainstorming grouping strategies for Lox buckets (of bridges) and gathering context on how types of bridges are distributed/use in practice Question: What makes a bridge usable for a given user, and how can we encode that to best ensure we're getting the most appropriate resources to people? 1. Are there some obvious grouping strategies that we can already consider? e.g., by PT, by bandwidth (lower bandwidth bridges sacrificed to open-invitation buckets?), by locale (to be matched with a requesting user's geoip or something?) 2. Does it make sense to group 3 bridges/bucket, so trusted users have access to 3 bridges (and untrusted users have access to 1)? More? Less? theodorsm: 2023-04-25 Last weeks: - Extended Pion dtls library to support hooking of client hellos, server hellos and certificate request (PR: https://github.com/pion/dtls/pull/631). Fingerprint generation of firefox and chrome + mimicking using the client hello hook have been moved to its own repo: https://github.com/theodorsm/covertDTLS - Analyzed the snowflake captures done in "Snowflake Anonymous Network Traffic Identification" paper: no handshakes found, so not relevant for me - Verified the consistency of the fingerprint generation Next weeks: - Add hook to pion/webrtc so it can be used in snowflake. - Test and validate mimicked client hello with snowflake. - Add randomized fingerprint Help with: Facilitator Queue: onyinyang meskio shelikhoo 1. First available staff in the Facilitator Queue will be the facilitator for the meeting 2. After facilitating the meeting, the facilitator will be moved to the tail of the queue
