User Feedback Report - June 2021
by Kulsoom Zahra 08 Jul '21

08 Jul '21

Greetings, everyone! This is a report of the work done by the Community Team in the past month and general user feedback that we've received across our official support channels. Report Period - May 24 upto July 1 --- Request Tracker --- Tickets resolved in the past month: 212 # New RT templates We gathered data on the most frequent issues faced by Tor users and turned their responses into RT articles/templates. This will help people working on the RT provide better user assistance. The following articles have been created or updated: 1. v2 onion deprecation 2. Will TB keep all my applications safe? Download files off Tor? Can someone access my files while using Tor? Etc. Here is a list of issues which got the most attention (at least 3 tickets on RT): # Tor Browser Breakdown of number of RT tickets received with respect to operating system: Windows (10,8,7 ...all the way upto XP) - 23 MacOS - 6 GNU/Linux - 2 Android - 11 (Note: This includes tickets where the user mentioned the operating system or it was evident from the issue they were running into or enclosed screenshots.) 1. 7 RT tickets - Failure to launch Tor Browser "Tor unexpectedly exited". We point users to the "Seven-point basic troubleshooting" article (template) on the RT to help users. 2. 6 RT tickets - Unable to access websites including bank sites and social media sites eg. Instagram. We point users to the "Banking sites blocked over Tor & Basic troubleshooting when users can't access any particular website" article (template) on the RT to help users. 3. 3 RT tickets - Error "RSA_get0_d could not be located in the dynamic link library tor.exe" on Windows. We have a GitLab ticket regarding this long standing issue. [1] 4. 3 RT tickets – TB crashes/ Goes blank after Windows 10 version 21H1 update. We have a GitLab ticket regarding this issue. [2] 5. 9 RT tickets - Installation Issue 2 - Windows : We ask them to download the correct version TB 32-bit or 64-bit. [3] 4 - Windows : Trying to install in wrong directory 3 - macOS : Error "no mountable file systems". We ask users to update their OS. 6. 3 RT tickets - Questions around VPN. We direct users to the article on the Support Portal. [4] and "Tor vs VPN" template. 7. 4 RT tickets - Change my guard/torrc file to not pick nodes from the same country. We teach users why modifying the way that Tor creates its circuits is strongly discouraged and point them to the article on the Support Portal. [5] 8. 3 RT tickets - Cannot upload files on Tor Browser for Android. Regarding this we have a ticket open on our GitLab [6]. This issue is already listed on 'Known Issues' section in the Tor Browser User Manual. [7] 9. 4 RT tickets - Error "Proxy Server Refused Connection". We ask users NOT to set TBA as their default browser and point them to the article in the Support Portal. [8] 10. 1 RT ticket – Error "java.io.IOException: Control port file not created". Regarding this we have a ticket open on our GitLab. [9] 11. 3 RT tickets – Confusion around F-Droid & what apk to download from our Download page. (under Android) [10] # Onion Services 5 tickets - v2 onion deprecation. Users were confused what to do, how to upgrade v2 to v3, will i be able to use Tor. We help users identify v2 and v3 onions, point them to the "v2 onion deprecation" article (template) on the RT . # Censorship Circumvention We got a total of 10 tickets requesting help to connect to Tor which have been from Iran, China and other countries. We provided private bridges for them. # UI/UX 1. Google Play Store We have recieved both positive and negative reviews. The negative ones are majorly about removing the "Quit" button which spans 11 comments. Other negative rating reviews revolve around not being able to download and slow speed of the browser. 2. Tor Stack Exchange - Statistics of what the discussion has been about (5 most active tags): tor-browser-bundle- 28 questions configuration (questions about configuring Tor software)- 19 questions hidden-services- 18 questions onion-routing - 5 questions anonymity- 10 questions security- 8 questions 3. Reddit - Discussion has mostly been around Tor + VPN, running Snowflake proxies, Unable to access sites, hosting onion servies, Cloudfare blocked over Tor and exit relays. If you have any suggestions, questions or want to discuss anything in detail please feel free to reach out to me and/or anyone from the Community Team!

Monthly Status Report for irl
by Iain R. Learmonth 06 Jul '21

06 Jul '21

Hi All, This is my monthly status report for work complete during June 2021. This month saw the releases of metrics-lib 2.17.0 and Onionoo 8.0-1.26.1. The new Onionoo release includes a number of fixes that me and Karsten had previously been working on related to reliability, and now also uses the IP Fire database that is used by core Tor. This means that the GeoIP information on Relay Search is also now based on the IP Fire database. Work has begun on importing bridge reachability testing into the Tor Metrics pipeline to improve the UX situation for bridge operators regarding knowing if their bridge is online or not. Since this work has been delayed, it is now expected to be completed by August 31st. Support for parsing bridgestrap metrics has been merged to the development branch of metrics-lib although this has not yet been included in a release. I'm expecting that will happen early this month. Finally, I have been around in Matrix/IRC to answer Metrics questions and on occasion to provide a little end-user support in #tor. I've been attending the weekly network health meetings and will continue to do so. If you've got any questions about anything I'm working on, just send me an email or chat on Matrix/IRC. Thanks, Iain.

Sponsor 38 (Shadow simulator) update
by Jim Newsome 29 Jun '21

29 Jun '21

We've shared the latest project update at https://github.com/shadow/shadow/discussions/1485; copied below: This is part of a series of periodic updates of development in Shadow. This work is sponsored by the NSF <https://github.com/shadow/shadow/blob/main/docs/nsf_sponsorship.md>. Previous update: 2021-04 <https://github.com/shadow/shadow/discussions/1274>. Shadow 2.0.0-pre release Shadow 2.0, which features the new process-based architecture <https://github.com/shadow/shadow/projects/1> is now in pre-release! We've merged <https://github.com/shadow/shadow/pull/1441> the |dev| branch into |main|, and tagged v2.0.0-pre.1 <https://github.com/shadow/shadow/releases/tag/v2.0.0-pre.1>. For users, this means: * Users cloning the repository at head will get Shadow 2.0 (pre). * We've /mostly/ stabilized some major changes to command-line options, config files, and topology files; enough so that users preparing to set up new simulations, or perhaps even heavily modify existing simulations or scripts, are better off targeting 2.0 than the Shadow 1.x series. * Because this is a pre-release, we're still reserving the right to make breaking changes without further bumping the version number, but we expect such changes to be minimal. Users migrating existing simulations and scripts should have a look at our migration guide <https://github.com/shadow/shadow/blob/main/docs/migrating_from_1x.md>. Progress since the last update We're still experimenting a bit with how to use GitHub's various project management tools. We've started using "projects" to represent Shadow releases. For example, you can see the issues for the v2.0.0 release here <https://github.com/shadow/shadow/projects/3>. Notable changes since the April update: (By milestone; #'s are GitHub PR or issue #'s): * Minimum viable prototype of process-based simulation architecture <https://github.com/shadow/shadow/milestone/16>: Closed, now that Shadow 2.x runs Tor simulations, and we've cross-validated simulation results with Shadow 1.x. o Added new internal APIs for accessing managed process memory, and used them to reduce the number of data copies. (#1264, #1280, #1290) * Fully support process-based simulation architecture <https://github.com/shadow/shadow/milestone/22> o This milestone is a bit of a catch-all, and includes a number of stability and performance improvements <https://github.com/shadow/shadow/pulls?q=is%3Apr+merged%3A2021-04-06..2021-…> that we wanted to finish before the full 2.0 release. o We're in the process of adding seccomp-based syscall interposition in combination with preload-based interposition. More on that in "What's next", below. So far we've already implemented and enabled it (#1452, #1471). * Convert existing modules to Rust <https://github.com/shadow/shadow/milestone/28> o We've ported several of Shadow's core internal objects into Rust (#1325, #1336, #1367, #1376, #1434). o We've reduced our reliance on globals to fit better in the Rust ownership model (#1386, #1393, #1396) * Updates to and new formats for Shadow configuration <https://github.com/shadow/shadow/milestone/27> o We've changed the configuration file format from XML to YAML (#1278). o We've changed the topology format from graphml (XML) to gml (YAML-like) (#1369). o Lots of updates to configuration options and defaults, making things clearer, giving more sensible defaults, and fixing parsing bugs. (#1263, #1266, #1270, #1304, #1305). o Additionally, we've /unified/ much of the configuration and command-line parsing to reduce code duplication and inconsistencies, and migrated it to Rust. (#1258, #1286) o Most numbers in our configuration and command-line options can now include explicit units. (#1300) o Made updates to tornettools to stay consistent with Shadow's new config option and network graph formats, and other 2.x changes (tornettools#7 <https://github.com/shadow/tornettools/pull/7>, tornettools#8 <https://github.com/shadow/tornettools/pull/8>, tornettools#17 <https://github.com/shadow/tornettools/pull/17>) * Code health and maintenance <https://github.com/shadow/shadow/milestone/24>: o Fixed some sources of nondeterminism in simulation results (#1460). o Improve and automate Tor simulation test (#1411, #1458). o Updated documentation for Shadow 2.0. (#1412, #1417, #1406, #1403) o Changed default install prefix from |~/.shadow| to |~/.local|. (#1404) o More <https://github.com/shadow/shadow/pulls?q=is%3Apr+merged%3A2021-04-06..2021-…> What's next We'll be continuing to gain experience running Shadow experiments with the 2.0.0 pre-release. We will be working to fix bugs, tie up some loose ends and smooth out some rough edges, and generally stabilize the code as we continue to prepare for a 2.0.0 stable release. We're currently tracking outstanding work on the 2.0.0 release page <https://github.com/shadow/shadow/projects/3>. Seccomp In the course of our work on the 2.x architecture we've largely been exploring two system call interposition mechanisms that allow us to co-opt running processes into a simulation - |LD_PRELOAD| (similar to what Shadow 1.x uses), and |ptrace|. While preload-based interposition has better performance, and plays better with debuggers, we've largely been focusing on the ptrace-based approach because it can reliably catch all syscalls without having to re-implement large parts of libc and/or rely on undocumented glibc implementation details. This has allowed us to work out all of the Shadow internals that needed to change to support interposition at the Linux system call interface. Recently, though, we added seccomp-based interposition to the preload-based interposition mode. This reliably catches any syscalls that would otherwise be missed by our |LD_PRELOAD| wrappers. We also have a working prototype of this mode of operation with /thread support/, which was previously the biggest missing functionality in preload-mode. Assuming thread support gets merged as expected and no other problems crop up, this is likely to become the new default mode of operation; it's faster than ptrace, and it allows us to trace the processes running in Shadow using debugging tools such as |gdb|. Happy simulating! The Shadow team <https://github.com/shadow/shadow/blob/master/docs/nsf-sponsorship.md#people>
