PieroV's Monthly Status Report, March 2025
by Pier Angelo Vendrame 01 Apr '25

01 Apr '25

Hi everyone, Here is my status report for March 2025. At the beginning of the month, I continued from where I left last month. First, I finished my proposal about integrating the Lox crate in the browser [tor-browser!1300]. I don't think it'll be merged as it is, but it already contains a lot of new code, so I prefer getting feedback before continuing this task. Then, I continued the rebase on Firefox 132 [tor-browser#43413]. Over the month, I worked on several issues related to Go and pluggable transports. I started by updating Go to 1.23.6 on alpha [tor-browser-build#41386]. Previously, we were on 1.22, but it went EOL, so we decided to update. However, we had to keep the old version for macOS since we still want to support macOS 10.15. We used to bootstrap Go starting from 1.4, the last version written in C. However, 1.23 required an additional version in the bootstrap chain, so I took the occasion to investigate the toolchain reproducibility. It's amazing: the 1.23.6 built with our chain matches bit-by-bit the official release from Google. Therefore, we switched to the official binaries as bootstrappers [tor-browser-build#41121]. Also about PTs, I created an automation to keep their license files updated [tor-browser-build#41411], and, in general, I reworked the way we include licenses for Tor and its dependencies [tor-browser-build!1188] (however, this MR hasn't been merged yet). I also worked a little bit on fingerprinting and screen size protection. First, I finalized the patch to spoof screen size differently from what we're currently doing [tor-browser#41747]. Even though it doesn't reduce entropy, it should help with some basic fingerprinting scripts and bot detection. However, we preferred to push the fix to 15.0 since we would like it to be tested for some time before shipping it to stable, and 14.5 is too close according to our plans. Then, I fixed an issue about letterboxing visible albeit disabled in some cases [tor-browser#42670]. I also investigated the upstream patches for window.devicePixelRatio in RFP, as Thorin found a problem with them [tor-browser#43239]. Eventually, I opened an upstream Bug [Bug 1954493] and sent a patch there first. I also worked on a few smaller issues, like adding string files with branding on Android [tor-browser#43464], adding a "What's new" link to the About dialog [tor-browser#42720], and more. Best, Pier [tor-browser#41747] https://gitlab.torproject.org/tpo/applications/tor-browser/-/issues/41747 [tor-browser#42670] https://gitlab.torproject.org/tpo/applications/tor-browser/-/issues/42670 [tor-browser#42720] https://gitlab.torproject.org/tpo/applications/tor-browser/-/issues/42720 [tor-browser#43239] https://gitlab.torproject.org/tpo/applications/tor-browser/-/issues/43239 [tor-browser#43413] https://gitlab.torproject.org/tpo/applications/tor-browser/-/issues/43413 [tor-browser#43464] https://gitlab.torproject.org/tpo/applications/tor-browser/-/issues/43464 [tor-browser!1300] https://gitlab.torproject.org/tpo/applications/tor-browser/-/merge_requests… [tor-browser-build#41121] https://gitlab.torproject.org/tpo/applications/tor-browser-build/-/issues/4… [tor-browser-build#41386] https://gitlab.torproject.org/tpo/applications/tor-browser-build/-/issues/4… [tor-browser-build#41411] https://gitlab.torproject.org/tpo/applications/tor-browser-build/-/issues/4… [tor-browser-build!1188] https://gitlab.torproject.org/tpo/applications/tor-browser-build/-/merge_re… [Bug 1954493] https://bugzilla.mozilla.org/show_bug.cgi?id=1954493

cve's monthly status report 03/2025
by Clara Engler 31 Mar '25

31 Mar '25

Hello tor-project@, this month I have done the following things for the Tor project. # Onion Service Reliability I performed research on the reliability of onion services in various setup environments, including arti to arti, ctor to ctor and the two ones being mixed together. These findings resulted in the conclusion that the arti implementation is well-done and has a similar failure of its ctor pedant, which is around 0.5% or 1 in every 200 connection being a failure. Those failures are flaky circuits which probably happen due to simply having bad luck while choosing the circuit. Nonetheless, those results are acceptable. Besides, this research has led to an improvement within the arti documentation, namely the addition of a method named `is_fully_reachable` which checks whether the `State` of a `tor-hsservice` indicates that it is reachable from the outside. This change was necessary because there are right now two states which indicate that the service is reachable, with only one of them sounding like a success. After all, this research led to the creation of the following tickets and merge requests in the arti repository: * arti#1887 * arti#1890 * arti!2850 # GPN23 I have opened a ticket (outreach#40103) for Tor activities at the GPN23 in Karlsruhe this June. I will be present at the event myself and I am open for giving a Tor related talk there too. This is however still early planning. # oniux This month, I continued working on oniux, namely statically integrating onionmasq into the oniux binary, so oniux users no longer need to provide a path to the onionmasq binary themselves; instead oniux is now a beautiful self-container monolithic binary. Besides all of this, I also did some research regarding the use of `user_namespaces(7)` in oniux with the eventual goal of oniux being capable to no longer need any `capabilities(7)`. This change is non-trivial and would probably require a rewrite of the tool in a shell scripting language, as a network stack such as [pasta](https://passt.top) would be required for proper functioning. Right now, this is not a priority but a nice to have. Our current use of capabilities is probably not a security risk, as all capabilities are being dropped very early on and no code originating from a malicious actor is executed with capabilities at all. Also, I have made two release tags for oniux this month: v0.1.0 and v0.2.0. Last but not least I have fixed a bug, namely that procfs was not remounted in the PID namespace created by oniux leading to an incorrect view when performing process related operations such as `ps aux`. After all, the following tickets have been addressed: * oniux#1 (for now) * oniux#2 * oniux#3 # onionmasq This month I gave onionmasq more attention again, this mainly included fixing various RenovateBot related updates and keeping this up-to-date in general. Besides this, I have performed some clean-ups and fixed some clippy warnings that occurred during the development. Also, as outlined in oniux, I have moved code a little bit around, meaning it is now possible to integrate onionmasq as a library into existing Rust application like I did with oniux. Last but not least I performed some testing with the onionmasq CI in order to hopefully make it possible to run the integration tests outside of privileged containers, there has not been much success there though. After all, my work cumulated in the following tickets/MR's: * onionmasq#135 * onionmasq#136 * onionmasq#137 * onionmasq#138 * onionmasq!404 * onionmasq!403 * onionmasq!401 (WIP) * onionmasq!400 * onionmasq!398 * onionmasq!397 (WIP) * onionmasq!393 # arti Besides the addition of the `is_fully_reachable` method, I also support and supported gabi@ in the release of the new arti version.

TPA-RFC-71: Emergency email deployments, phase B
by Antoine Beaupré 26 Mar '25

26 Mar '25

Hi, So TPA has adopted this proposal, internally, to make yet another set of emergency changes to our mail system, to respond to critical issues affecting delivery and sustainability of our infrastructure. I encourage you to read the "Affected users" section and "Timeline" below. In particular, we will be experimenting with "sender rewriting" soon, which will involve mangling emails we forward around to try and fix deliverability on those. The schleuder mailing list will also move servers. Maintenance windows for those changes will be communicated separately. Thank you for your attention! PS: and no, we didn't submit this for adoption to everyone, because it was felt it was mostly technical changes that didn't warrant outside approval, let me know if that doesn't make sense, of course. -- Antoine Beaupré torproject.org system administration --- title: TPA-RFC-71: Emergency email deployments, phase B costs: staff approval: TPA affected users: all torproject.org email users deadline: 5 days, 2024-10-01 status: draft discussion: https://gitlab.torproject.org/tpo/tpa/team/-/issues/41778 --- Summary: deploy a new sender-rewriting mail forwarder ASAP, migrate mailing lists off the legacy server to a new machine, migrate the remaining Schleuder list to the Tails server, upgrade `eugeni`. Table of contents: - Background - Proposal - Actual changes - Mailman 3 upgrade - New sender-rewriting mail exchanger - Schleuder migration - Upgrade legacy mail server - Goals - Must have - Nice to have - Non-Goals - Scope - Affected users - Personas - Timeline - Optimistic timeline - Worst case scenario - Alternatives considered - References - History - Personas descriptions - Ariel, the fundraiser - Blipblop, the bot - Gary, the support guy - John, the contractor - Mallory, the director - Nancy, the fancy sysadmin - Orpheus, the developer # Background In [#41773][], we had yet another report of issues with mail delivery, particularly with email forwards, that are plaguing Gmail-backed aliases like grants@ and travel@. [#41773]: https://gitlab.torproject.org/tpo/tpa/team/-/issues/41773 This is becoming critical. It has been impeding people's capacity of using their email at work for a while, but it's been more acute since google's recent changes in email validation (see [#41399][]) as now hosts that have adopted the SPF/DKIM rules are bouncing. [#41399]: https://gitlab.torproject.org/tpo/tpa/team/-/issues/41399 On top of that, we're way behind on our buster upgrade schedule. We still have to upgrade our primary mail server, `eugeni`. The plan for that ([TPA-RFC-45][], [#41009][]) was to basically re-architecture everything. That won't happen fast enough for the LTS retirement which we have crossed two months ago (in July 2024) already. [TPA-RFC-45]: https://gitlab.torproject.org/tpo/tpa/team/-/wikis/policy/tpa-rfc-45-mail-a… [#41009]: https://gitlab.torproject.org/tpo/tpa/team/-/issues/41009 So, in essence, our main mail server is unsupported now, and we need to fix this as soon as possible Finally, we also have problems with certain servers (e.g. `state.gov`) that seem to dislike our bespoke certificate authority (CA) which makes *receiving* mails difficult for us. # Proposal So those are the main problems to fix: - Email forwarding is broken - Email reception is unreliable over TLS for some servers - Mail server is out of date and hard to upgrade (mostly because of Mailman) ## Actual changes The proposed solution is: - **Mailman 3 upgrade** ([#40471][]) - **New sender-rewriting mail exchanger** ([#40987][]) - **Schleuder migration** - **Upgrade legacy mail server** ([#40694][]) [#40471]: https://gitlab.torproject.org/tpo/tpa/team/-/issues/40471 [#40987]: https://gitlab.torproject.org/tpo/tpa/team/-/issues/40987 [#40694]: https://gitlab.torproject.org/tpo/tpa/team/-/issues/40694 ### Mailman 3 upgrade Build a new mailing list server to host the upgraded Mailman 3 service. Move old lists over and convert them while retaining the old archives available for posterity. This includes lots of URL changes and user-visible disruption, little can be done to work around that necessary change. We'll do our best to come up with redirections and rewrite rules, but ultimately this is a disruptive change. This involves yet another authentication system being rolled out, as Mailman 3 has its own user database, just like Mailman 2. At least it's one user per site, instead of per list, so it's a slight improvement. This is issue [#40471][]. ### New sender-rewriting mail exchanger This step is carried over from [TPA-RFC-45][], mostly unchanged. [Sender Rewriting Scheme]: https://en.wikipedia.org/wiki/Sender_Rewriting_Scheme [postsrsd]: https://github.com/roehling/postsrsd [postforward]: https://github.com/zoni/postforward Configure a new "mail exchanger" (MX) server with TLS certificates signed by our normal public CA (Let's Encrypt). This replaces that part of `eugeni`, will hopefully resolve issues with `state.gov` and others ([#41073][], [#41287][], [#40202][], [#33413][]). [#33413]: https://gitlab.torproject.org/tpo/tpa/team/-/issues/33413 [#40202]: https://gitlab.torproject.org/tpo/tpa/team/-/issues/40202 [#41287]: https://gitlab.torproject.org/tpo/tpa/team/-/issues/41287 [#41073]: https://gitlab.torproject.org/tpo/tpa/team/-/issues/41073 This would handle forwarding mail to other services (e.g. mailing lists) but also end-users. To work around reputation problems with forwards ([#40632][], [#41524][], [#41773][]), deploy a [Sender Rewriting Scheme][] (SRS) with [postsrsd][] (packaged in Debian, but [not in the best shape][]) and [postforward][] (not packaged in Debian, but zero-dependency Golang program). It's possible deploying [ARC][] headers with [OpenARC][], Fastmail's [authentication milter][] (which [apparently works better][]), or [rspamd's arc module][] might be sufficient as well, to be tested. [OpenARC]: https://tracker.debian.org/pkg/openarc [not in the best shape]: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1017361 Having it on a separate mail exchanger will make it easier to swap in and out of the infrastructure if problems would occur. The mail exchangers should also sign outgoing mail with DKIM, and *may* start doing better validation of incoming mail. [authentication milter]: https://github.com/fastmail/authentication_milter [apparently works better]: https://old.reddit.com/r/postfix/comments/17bbhd2/about_arc/k5iluvn/ [rspamd's arc module]: https://rspamd.com/doc/modules/arc.html [#41524]: https://gitlab.torproject.org/tpo/tpa/team/-/issues/41524 [#40632]: https://gitlab.torproject.org/tpo/tpa/team/-/issues/40632 [ARC]: http://arc-spec.org/ ### Schleuder migration Migrate the remaining mailing list left (the Community Council) to the Tails Shleuder server, retiring our Schleuder server entirely. This requires configuring the Tails server to accept mail for `(a)torproject.org`. Note that this may require changing the addresses of the existing Tails list to `(a)torproject.org` if Schleuder doesn't support virtual hosting (which is likely). ### Upgrade legacy mail server Once Mailman has been safely moved aside and is shown to be working correctly, upgrade Eugeni using the normal procedures. This should be a less disruptive upgrade, but is still risky because it's such an old box with lots of legacy. One key idea of this proposal is to keep the legacy mail server, `eugeni`, in place. It will continue handling the "MTA" (Mail Transfer Agent) work, which is to relay mail for other hosts, as a legacy system. The full eugeni replacement is seen as too complicated and unnecessary at this stage. The legacy server will be isolated from the rewriting forwarder so that outgoing mail is mostly unaffected by the forwarding changes. ## Goals This is not an exhaustive solution to all our email problems, [TPA-RFC-45][] is that longer-term project. ### Must have - Up to date, supported infrastructure. - Functional legacy email forwarding. ### Nice to have - Improve email forward deliverability to Gmail. ### Non-Goals - **Clean email forwarding**: email forwards *may* be mangled and rewritten to appear as coming from `(a)torproject.org` instead of the original address. This will be figured out at the implementation stage. - **Mailbox storage**: out of scope, see [TPA-RFC-45][]. It is hoped, however, that we *eventually* are able to provide such a service, as the sender-rewriting stuff might be too disruptive in the long run. - **Technical debt**: we keep the legacy mail server, `eugeni`. - **Improved monitoring**: we won't have a better view in how well we can deliver email. - **High availability**: the new servers will not add additional "single point of failures", but will not improve our availability situation (issue [#40604][]) [#40604]: https://gitlab.torproject.org/tpo/tpa/team/-/issues/40604 ## Scope This proposal affects the all inbound and outbound email services hosted under `torproject.org`. Services hosted under `torproject.net` are *not* affected. It also does *not* address directly phishing and scamming attacks ([#40596][]), but it is hoped the new mail exchanger will provide a place where it is easier to make such improvements in the future. [#40596]: https://gitlab.torproject.org/tpo/tpa/team/-/issues/40596 ## Affected users This affects all users which interact with `torproject.org` and its subdomains over email. It particularly affects all "tor-internal" users, users with LDAP accounts, or forwards under `(a)torproject.org`, as their mails will get rewritten on the way out. ### Personas Here we collect a few "personas" and try to see how the changes will affect them, largely derived from [TPA-RFC-45][], but without the alpha/beta/prod test groups. For *all* users, a common impact is that emails will be rewritten by the sender rewriting system. As mentioned above, the impact of this still remains to be clarified, but at least the hidden `Return-Path` header will be changed for bounces to go to our servers. Actual personas are in the Reference section, see [Personas descriptions][]. | Persona | Task | Impact | |---------|-------------|--------------------------------------------------------------------------| | Ariel | Fundraising | Improved incoming delivery | | Blipbot | Bot | No change | | Gary | Support | Improved incoming delivery, new moderator account on mailing list server | | John | Contractor | Improved incoming delivery | | Mallory | Director | Same as Ariel | | Nancy | Sysadmin | No change in delivery, new moderator account on mailing list server | | Orpheus | Developer | No change in delivery | [Personas descriptions]: #personas-descriptions ## Timeline ### Optimistic timeline - Late September (W39): issue raised again, proposal drafted (now) - October: - W40: proposal approved, installing new rewriting server - W41: rewriting server deployment, new mailman 3 server - W42: mailman 3 mailing list conversion tests, users required for testing - W43: mailman 2 retirement, mailman 3 in production - W44: Schleuder mailing list migration - November: - W45: `eugeni` upgrade ### Worst case scenario - Late September (W39): issue raised again, proposal drafted (now) - October: - W40: proposal approved, installing new rewriting server - W41-44: difficult rewriting server deployment - November: - W44-W48: difficult mailman 3 mailing list conversion and testing - December: - W49: Schleuder mailing list migration vetoed, Schleuder stays on `eugeni` - W50-W51: `eugeni` upgrade postponed to 2025 - January 2025: - W3: `eugeni` upgrade # Alternatives considered We decided to not just run the sender-rewriting on the legacy mail server because too many things are tangled up in that server. It is just too risky. We have also decided to not upgrade Mailman in place for the same reason: it's seen as too risky as well, because we'd first need to upgrade the Debian base system and if that fails, rolling back is too hard. # References - [discussion issue][] [discussion issue]: https://gitlab.torproject.org/tpo/tpa/team/-/issues/41778 ## History This is the the *fifth* proposal about our email services, here are the previous ones: * [TPA-RFC-15: Email services][] (rejected, replaced with TPA-RFC-31) * [TPA-RFC-31: outsource email services][] (rejected, in favor of TPA-RFC-44 and following) * [TPA-RFC-44: Email emergency recovery, phase A][] (standard, and mostly implemented except the sender-rewriting) * [TPA-RFC-45: Mail architecture][] (still draft) [TPA-RFC-15: Email services]: policy/tpa-rfc-15-email-services [TPA-RFC-31: outsource email services]: policy/tpa-rfc-31-outsource-email [TPA-RFC-44: Email emergency recovery, phase A]: policy/tpa-rfc-44-email-emergency-recovery [TPA-RFC-45: Mail architecture]: policy/tpa-rfc-45-mail-architecture ## Personas descriptions ### Ariel, the fundraiser Ariel does a lot of mailing. From talking to fundraisers through their normal inbox to doing mass newsletters to thousands of people on CiviCRM, they get a lot done and make sure we have bread on the table at the end of the month. They're awesome and we want to make them happy. Email is absolutely mission critical for them. Sometimes email gets lost and that's a major problem. They frequently tell partners their personal Gmail account address to work around those problems. Sometimes they send individual emails through CiviCRM because it doesn't work through Gmail! Their email forwards to Google Mail and they now have an LDAP account to do email delivery. ### Blipblop, the bot Blipblop is not a real human being, it's a program that receives mails and acts on them. It can send you a list of bridges (bridgedb), or a copy of the Tor program (gettor), when requested. It has a brother bot called Nagios/Icinga who also sends unsolicited mail when things fail. There are also bots that sends email when commits get pushed to some secret git repositories. ### Gary, the support guy Gary is the ticket overlord. He eats tickets for breakfast, then files 10 more before coffee. A hundred tickets is just a normal day at the office. Tickets come in through email, RT, Discourse, Telegram, Snapchat and soon, TikTok dances. Email is absolutely mission critical, but some days he wishes there could be slightly less of it. He deals with a lot of spam, and surely something could be done about that. His mail forwards to Riseup and he reads his mail over Thunderbird and sometimes webmail. Some time after TPA-RFC_44, Gary managed to finally get an OpenPGP key setup and TPA made him a LDAP account so he can use the submission server. He has already abandoned the Riseup webmail for TPO-related email, since it cannot relay mail through the submission server. ### John, the contractor John is a freelance contractor that's really into privacy. He runs his own relays with some cools hacks on Amazon, automatically deployed with Terraform. He typically run his own infra in the cloud, but for email he just got tired of fighting and moved his stuff to Microsoft's Office 365 and Outlook. Email is important, but not absolutely mission critical. The submission server doesn't currently work because Outlook doesn't allow you to add just an SMTP server. John does have an LDAP account, however. ### Mallory, the director Mallory also does a lot of mailing. She's on about a dozen aliases and mailing lists from accounting to HR and other unfathomable things. She also deals with funders, job applicants, contractors, volunteers, and staff. Email is absolutely mission critical for her. She often fails to contact funders and critical partners because `state.gov` blocks our email -- or we block theirs! Sometimes, she gets told through LinkedIn that a job application failed, because mail bounced at Gmail. She has an LDAP account and it forwards to Gmail. She uses Apple Mail to read their mail. ### Nancy, the fancy sysadmin Nancy has all the elite skills in the world. She can configure a Postfix server with her left hand while her right hand writes the Puppet manifest for the Dovecot authentication backend. She browses her mail through a UUCP over SSH tunnel using mutt. She runs her own mail server in her basement since 1996. Email is a pain in the back and she kind of hates it, but she still believes entitled to run their own mail server. Her email is, of course, hosted on her own mail server, and she has an LDAP account. She has already reconfigured her Postfix server to relay mail through the submission servers. ### Orpheus, the developer Orpheus doesn't particular like or dislike email, but sometimes has to use it to talk to people instead of compilers. They sometimes have to talk to funders (`#grantlyfe`), external researchers, teammates or other teams, and that often happens over email. Sometimes email is used to get important things like ticket updates from GitLab or security disclosures from third parties. They have an LDAP account and it forwards to their self-hosted mail server on a OVH virtual machine. They have already reconfigured their mail server to relay mail over SSH through the jump host, to the surprise of the TPA team. Email is not mission critical, and it's kind of nice when it goes down because they can get in the zone, but it should really be working eventually. -- Antoine Beaupré torproject.org system administration -- tpa-team mailing list tpa-team(a)lists.torproject.org https://lists.torproject.org/cgi-bin/mailman/listinfo/tpa-team

TPA-RFC-83: Mail log retention
by Antoine Beaupré 18 Mar '25

18 Mar '25

Summary: extend the retention limit for mail logs to 10 days # Background We currently rotate mail logs daily and keep them for 5 days. That's great for privacy, but not so great for people having to report mail trouble in time. In particular, when there are failures with mail sent just before the weekend, it gives users a very short time frame to report issues. # Proposal Extend the retention limit for mail (`postfix` and `rspamd`) logs to 10 days: one week, plus "flexible Friday", plus "weekend". ## Goals Being able to debug mail issues when users notice and/or report them after five days. ## Tasks Adjust logrotate configuration for syslog-ng and rspamd. ## Scope All TPA servers. ## Affected users Sysadmins and email users, which is pretty much everyone. ## Timeline Logging policies will be changed on Wednesday March 19th. # References TPA has various log policies for various services, which we have been meaning to document for a while. This policy proposal doesn't cover for that, see [tpo/tpa/team#40960][] for followup on that more general task. [tpo/tpa/team#40960]: https://gitlab.torproject.org/tpo/tpa/team/-/issues/40960 See also the [discussion issue][].

They have snowflake.torproject.net hardcoded and do not know how to connect to any other relay. If a client were to request a connection to the snowflake-02 relay, and was assigned such an old proxy, the proxy would connect to snowflake-01 anyway, and leave the client with a Tor fingerprint mismatch error. * Therefore adjusting the presumedPatternForLegacyClient on the broker to accept old proxies would not work. Old proxies (that don't support relay patterns) would start getting clients again, but any clients that request a relay other than snowflake-01 would get failed connections. * There's no facility on the broker to, say, match old proxies only with those clients that happen to request snowflake-01. Once a proxy is in the pool, it's treated equally to all other proxies. Such a matching facility could conceivably be implemented, but none currently exists. It may not be worth the complexity anyway. * The intention therefore was that the broker simply reject old proxies (that do not send a relay pattern). That is, in effect, what is now happening, but it happens by a roundabout way: proxy polls and doesn't set an allowed relay pattern → broker assigns a default allowed relay pattern that never works → broker rejects the proxy poll because of the relay pattern mismatch. * The downsides of the status quo are that (1) the broker logs are full of "rejected relay pattern from proxy" errors, and (2) the old proxies just keep on uselessly polling. * Consensus for dealing with the current situation: * Make the broker code more straightforward with respect to rejecting old proxies: do it at an early stage, don't even bother assigning a default relay pattern to them (and remove the code that does). * Update metrics/logging. Disable the "rejected relay pattern from proxy" at the broker, and just keep it as a metrics counter. * For the future, it would be handy if there were a feature whereby the broker, by sending a specific kind of response to a proxy, could cause the proxy to disable itself (say, stop polling for 24h) and log a visible message to the operator. In effect, we could push the "rejected relay pattern from proxy" error out to the proxy logs, which would (1) stop proxies that only support an obsolete protocol from uselessly polling, and (2) inform the operator and encourage them to upgrade. * In the absence of such a feature, it might be possible to find a way to crash old proxies by sending a specific kind of broker response. For example, an overlong HTTP body, or a JSON unmarshaling error. Even if it is not possible to convey a reason why it is happening to the proxy operator, it might get the operators attention, and at least reduce unhelpful polling volume. * One complication with this idea: some proxies are running in a container, or similar, and are configured to auto-restart after they exit. Proxies that work this way might paradoxically increase their effective polling rate if remotely disabled, because there's no interval rate limiting on the first poll. * Even so, if we find such a "disable" broker response, we could try having the broker send it to old proxies (those that don't support relay patterns) for 1h. The ones that are configured to restart will restart, but the one that are not will stop operating. * Related issue: "Let the broker inform proxies how often to poll" https://gitlab.torproject.org/tpo/anti-censorship/pluggable-transports/snow…. The broker could send a time many hours in the future. This would help with reducing the polling rate, even if it does not result in the proxy log message. * A standalone proxy auto-update mechanism could be an alternative or addition to support for a broker "disable" signal. == Actions == == Interesting links == * == Reading group == * We will discuss "" on * * Questions to ask and goals to have: * What aspects of the paper are questionable? * Are there immediate actions we can take based on this work? * Are there long-term actions we can take based on this work? * Is there future work that we want to call out in hopes that others will pick it up? == Updates == Name: This week: - What you worked on this week.

Haidi February '25 Report
by Haidi 11 Mar '25

11 Mar '25

Hi! Below is my February’25 (Period: 2025-02-01 - 2025-02-28) report! In February, I began working on tests and documentation, focusing on integrating pluggable transports with little-t-tor on Windows. I then collected data across different operating systems and contributed to the corresponding GitLab documentation ticket. Spent some time learning the workflow for merging and committing documents in GitLab for the Tor Project. *Add documentation about using pluggable transports with little-t-tor* <https://gitlab.torproject.org/tpo/web/support/-/issues/378#top> https://gitlab.torproject.org/tpo/web/support/-/issues/378 Thanks, Haidi
