3 Apr 2017 network team meeting: status reports and meetbot notes
by Nick Mathewson 03 Apr '17

03 Apr '17

Hi! I'm trying to be a little more proactive in sending out links to our meetbot logs for the network team. We're also trying a new format where we put our status reports on a pad in parallel and talk about them during the meeting. So I'm going to paste from the pad into this mail, and include a link to the meetbot log at the end of the mail. If you want to ask us about something you see here, please use a public mailing list: sending emails to individual developers is a tiny bit creepy sometimes. ================================================== Weekly network team meeting 3 April 2017 New format! To discuss: * Rotating roles * This pad format * putting out 0.3.0 -- anything else? * New dirauth in 030 stable? * GSoC * We didn't triage 0.3.1 in Amsterdam. =================================================== username: last week: * * this week: * * nickm: last week: * got back from amsterdam; that went well, both in terms of work done and in negative d(drama)/dt * Resurrected calltool, my assembly-reading objdump-parsing callgraph generator. Needs more work; output still isn't right. available at https://gitweb.torproject.org/user/nickm/calltool.git/ . output is not to be trusted yet. * a couple of small cleanup patches (remove tor-checkkey, use openssl includes less) * general consensus diff backend hacking (sponsor4) * lots of talking about crypto, followups, etc this week: * I'm hoping to put out 0.3.0.5-rc. Help? * I'm hoping to start merging mikeperry's netflow patches. Help? * Gotta go through all our notes from the meeting and see what turns into a to-do item. * Going to see how far I can get on the consensus diff implementation. It would be cool to have it working by some time next week, but that's ambitious. * We've got to look at gsoc applications; they're due today. * Enjoy the lovely boston weather. asn: last week: - returned from amsterdam - wrote a blog post about UX of onion addresses. hopefully publishing today. - started looking into ed25519 blinding stuff. - replied to some of the email backlog. this week: - figure out what to do with ed25519 key clamping and AONT construction - review ed25519 blinding code. update spec. add docs. - maybe start thinking about cpath crypto API for prop224. not sure if i will have time. pastly: 1. Finishing up work on getting my kist code ready to be reviewed by my employer so I can share it with Tor to get feedback. As part of that, I'm planning on implementing run-time switching between schedulers with function pointers. For example, scheduler_run would be a function pointer to scheduler_run_vanilla or scheduler_run_kist based on the UseKIST torrc option. Changing UseKIST and reloading Tor would just update pointers and clean up memory if necessary. Does that sound like a mergable idea? (yes, sure, assuming it's clean :) -NM) 2. I saw that the network team is working on a new responsibility rotation, including front-line support in #tor. First, I'd like to volunteer to help with front-line support. (sounds good! we should all take turns. -NM) Second, I think +R should be removed from #tor, at least when I am actively online. We get roughly zero spam right now, but we also get very little support requests. I think this is relevant to this meeting if network team is wanting to get more active on the front-line. (not a network-team call afaik -NM) catalyst: last week: * returned from AMS * polished my 13790 patch * started looking at 0.3.1.x milestone bugs this week: * find a few 0.3.1.x milestone bugs to work on ("revision_stalled" etc. where the user has been unresponsive about revisions) * learn more about PT and anti-censorship Sebastian: Rust team founded with Alex and Chelsea Lots of Rust hacking We can link Rust now :) Started a consdiff implementation. No unsafe code, 50% performance of C impl without tweaks (C is somewhat optimized) dgoulet: last week: - Amsterdam was very productive for me. Worked a bunch with asn on prop224 implementation. Came back quite unhealthy so I'm working through that. I've emptied my email stack for now. I still have quite the TODO (network team related and other Tor things) so I'll try to go over it this afternoon. - Bad relay world is moving with some discussions and soon blog post. this week: - I'm planning this week to finalize #20657 once and for all then go crazy on testing and fuzzing (for which I had a good workshop in AMS, thanks nickm!) haxxpop: last week: * Rewrite the get_responsible_hsdirs according to the comments of dgoulet and asn https://github.com/haxxpop/tor/pull/3/commits this week: * I will refactor that get_responsible_hsdirs if there are more comments from the team * Maybe find some other prop224 stuff to do ahf: since last meeting: - Worked on prop#278 issues: #21667 + #21662 + #21663. - Implemented proposal #274 in issue #21641. - Helped review #21643, #21645, and #21651. - Looked into a PT regression I caused in #21757 and thereafter investigated if the regression would impact tor-fw-helper. Looked into how tor-fw-helper worked, what it is, and if there was still a need for the tool. Discussed deprecation strategy with Nick. - Looked into our old IPv6 roadmap, issues related to IPv6 code as preparation for the Amsterdam meeting and GSoC proposal. - Went to Amsterdam, met and talked to a lot of new people. - Hosted a sponsor 4 session with Karsten (metrics team) + Nathan (guardian project). - Joined Sebastian and Chelsea's work on Rust porting. Read up on Rust. this week: - Finishing prop#278 related issues: currently working on splitting them up into reviewable patches that fits the relevant issues. - Walk over my Amsterdam notes for different ideas and projects. - Look into next steps for Sponsor#4 tasks. - Need to talk to Karsten about the possible impact some of the sponsor4 stuff might have to the metrics team. (happy to talk, possibly after the meeting/tomorrow! -karsten) isis: since last meeting: - wrote more of the paper/design spec that is due for my OTF deliverable (#10 on https://people.torproject.org/~isis/otf-etfp-sow.pdf) - took two days off last week since the dev meeting went over the weekend - read a bunch of appengine documentation to get the meek reflector for bridgedb working - sketched out some UX stuff for the distributor and the API that will be available to TB - several talks with different rustlang developers who are excited and want to know what we want out of rust this week: - still cruching a bit to finish the OTF deliverables by the 22nd, so more of the same work Mike: Last week: * I spoke at IETF * Recovered from AMS * Finishing up the Firefox code review. About 1 more day of work. This week: * Resume working on Prop#254 * Do some followup from AMS * More Meetings yawning: this week: * Maybe poke at my optimized lattice crypto code some more. Isabela: Last week: Worked on user growth strategy update - hope to share it by eow Worked on final report for ISC Tried to catch on AMS meetings notes This week: Get user growth strategy update done catch up with the team on follow ups from the meeting work on March report for sponsor4 =============================== Meetbot logs from the IRC meeting: http://meetbot.debian.net/tor-dev/2017/tor-dev.2017-04-03-17.00.html -- Nick

Tor project's use of Mailman
by johny 25 Mar '17

25 Mar '17

Hi all, I'm currently working on my GSoC proposal for the GNU Mailman project, which aims to implement encrypted mailing lists. I noticed that Tor project uses Mailman and has a few private lists as well. I think that Tor project's private lists might be a great example that could use such encrypted lists. What requirements would Tor project have of such encrypted mailing list? This would help me better understand potential uses of encrypted mailing lists in a real environment. My proposal uses PGP/MIME. A short description follows: It establishes a list keypair which subscribers use to encrypt their messages with. A user needs to present a PGP public key on subscription which will be later used to encrypt messages from the list. List owner moderates the list and accepts users subscription. User has to prove ownership of the key by signing a confirmation token. Subscriber then sends messages encrypted with list key and signed with the one he subscribed with. He receives messages encrypted to his key and signed by the original author as well as the list itself. Commands will require signature and confirmation too. A more detailed proposal can be found in the links below. -Jan ----- [Project idea]: https://wiki.list.org/DEV/Google%20Summer%20of%20Code%202017#Encrypted_List… [Proposal draft (site)]: https://neuromancer.sk/page/gsoc/mailman [Proposal draft (PDF)]: https://neuromancer.sk/static/mailman.pdf

U.S. border crossing guide
by Franklin Bynum 20 Mar '17

20 Mar '17

Many of you will be crossing the U.S. border soon because of travel to the Tor Meeting. I was supposed to be there, but child care obligations will keep me stateside. As an immigration lawyer and a member of the Tor community, I would like to give you all a crash course in crossing the U.S. border. This document does not discuss anything related to seeking asylum or other refugee status. If you hold or may seek refugee status of any kind, seek professional help. == If you are not a U.S. citizen == If you have permanent resident status, have a visa or are a national of a country that is part of the Visa Waiver Program [fn:1], when you present yourself to an immigration officer at the border the officer evaluates whether you are inadmissible under any of the many grounds in section 212 of the Immigration and Nationality Act. [fn:2] Having a travel document does not guarantee you entry. All people who are not U.S. citizens are subject to the entire slate of grounds of inadmissibility, including long-time permanent residents. If the official finds that you are inadmissible, you will be denied entry and detained pending your removal. Some people, like permanent residents, will be detained for weeks until they can see an immigration judge to receive a hearing on their inadmissibility. The agent will likely ask you questions about who you are and where you are going. You have a right under the United States constitution to refuse to answer questions, but if you refuse to answer the officer will surely deny you entry and will likely detain you for further questioning. Immigration officers have wide latitude to question you and deny you entry. You have little legal recourse against this. Read the grounds of inadmissibility [fn:1] and you will see the many ways you can be lawfully denied entry, even as a permanent resident. If you have ever been arrested or otherwise feel that you may be singled out, contact me or another immigration lawyer before you intend to cross the border. == If you are a U.S. citizen == The government has to let you in. They can, however, detain you for questioning and search you and your property. == For everyone: border searches == At the U.S. border, immigration officers may search you basically for any reason, or no reason. They do not have to articulate any suspicion. They can, and do routinely, go through all your property, including your devices. They can clone your hard drive. They can attach forensic tools to your phone or other device. They can seize your item as evidence against you. You can not do anything to stop this. The one things you can do is refuse to give passwords. You have a constitutional right to remain silent that is fairly strong here. If you are a U.S. citizen, they have no recourse except to detain, question, and intimidate you further. They cannot detain you for an unreasonable amount of time, measured by what an imaginary "objective reasonable person" would think is reasonable. This amount of time will be longer than you personally think is reasonable. If you are a non-citizen, they could deny you entry for your refusal. If you are stopped and your device is searched or you are asked for passwords, contact me. == About me == I am a relay operator, a lawyer, and partner to Alison. I am in IRC at @frabyn. My practice is criminal defense and immigration in Texas. My website is https://bynumlaw.net/ * Footnotes [fn:1] https://travel.state.gov/content/visas/en/visit/visa-waiver-program.html [fn:2] https://www.uscis.gov/ilink/docView/SLB/HTML/SLB/0-0-0-1/0-0-0-29/0-0-0-200… -- Franklin Bynum Lawyer 2814 Hamilton Street Houston, Texas 77004 +1 713 343-8844

Cor Tor Team sponsor4 February work report
by isabela 16 Mar '17

Core Tor Team February 2017 Report We started to work on collecting measurements[1] of our consensus diff proposal (prop140) to analyze how much data Tor downloads today, how much data it would download after the consensus diff implementation is complete, and what we could do in order to reduce the downloaded volume further. We created the following tools[2] to help us collect and analyze our data: The populate.py and analyze.py scripts are for looking at the amount and causes ofmicrodescriptor change over time. The populate-consenus and analyze-consensus.py scripts look at the amount and causesof routerstatus change over time in the consensus. The diff-size tool determines the mean size for ed-based consensus diffs, after various consensus transformations and diff compression algorithms. With these tools, we were able to improve[3] Proposal 140 [4] "Provide diffs between consensuses", which is an important part for us to do to achieve our objective. They also lead to the creation of proposals 274 through 276, each of which will reduce the required bandwidth for directory operations (see below). We also created tools[5] to analyze different compression schemes related to Proposal 278 [6] "Directory Compression Scheme Negotiation", which is one of the design proposals we plan to implement in order to achieve our goals under this objective. We have the results of the first collection/analyses[7]. The other proposals related to directory bandwidth savings are: Proposal 274 [8] - Rotate onion keys less frequently Proposal 275 [9] - Stop including meaningful "published" time in microdescriptor consensus Proposal 276 [10] - Report bandwidth with lower granularity in consensus documents [1] https://trac.torproject.org/projects/tor/ticket/21205 [2] https://github.com/nmathewson/consensus-diff-analysis [3] https://trac.torproject.org/projects/tor/ticket/21209 [4] https://github.com/torproject/torspec/blob/master/proposals/140-consensus-d… [5] https://gitlab.com/ahf/tor-sponsor4-compression [6] https://github.com/torproject/torspec/blob/master/proposals/278-directory-c… [7] https://docs.google.com/spreadsheets/d/1devQlUOzMPStqUl9mPawFWP99xSsRM8xWv7… [8] https://github.com/torproject/torspec/blob/master/proposals/274-rotate-onio… [9] https://github.com/torproject/torspec/blob/master/proposals/275-md-publishe… [10] https://github.com/torproject/torspec/blob/master/proposals/276-lower-bw-gr… [11] https://github.com/torproject/torspec/blob/master/proposals/277-detect-id-s…

Anyone know what caused the remarkable jump in direct and obfs3 users from the UAE that began on 16 Jan and 06 Feb, respectively? Sorry if I already missed the discussion about this. https://metrics.torproject.org/userstats-relay-country.html?start=2017-01-1… https://metrics.torproject.org/userstats-bridge-country.html?start=2017-02-… Thanks!
