Hi, all!

You can find the transcript from our weekly meeting at http://meetbot.debian.net/tor-dev/2017/tor-dev.2017-06-26-16.59.html

Here are our notes: -----------------------

Network team pad, for 26 June Meeting (or 27 June, for those in UTC+5 or later)

Notes from last week's meeting: * https://lists.torproject.org/pipermail/tor-project/2017-June/001208.html (Did we do what we had planned?)

Announcements and reminders: * review-group-18 is still not cleared. We have 3 tickets left in needs_review there which need to get reviews before nickm makes a review-group-19. * review-group-19 will come once the last 3 tickets in review-group-18 are done. * There are still 34 tickets in 0.3.1.x, including 9 in status "new" with no owner. We need to get 0.3.1.x done! * Employees: remember harvest. [also, if you have pending expense reports, try to submit them before end of june - you can do that via harvest as well if you like] * Isabela will ping people to start collecting information for nsf reports

Things we should talk about: * We need a PT person (or at least point of contact) * How important is noise for padding statistics? Mike is thinking "Not very" compared to the type of attack described vs related guard discovery attacks I want to fix first.

Tasks for after the meeting: * July team rotation schedule is available at: https://trac.torproject.org/projects/tor/wiki/org/teams/NetworkTeam/TeamRota...

teor: Last week: * Fixed a nasty security bug in PrivCount, released 1.0.2, and upgraded all the things * Deployed PrivCount HSDir upload stats on a relay for testing * Looked at all the privcount-tagged trac tickets and updated the PrivCount TODO lists * Tried to help out with the PaddingStatistics implementation #17857 etc. * Stop relays from knowing HS client and service addresses #22688, #22689 * Added a hs-network-min network to chutney: #22667 * Logged a few bugs in Tor and Tor Browser This week: * Document the PrivCount HSDir upload stats test outcomes * Prioritise the remaining 6 hidden service events (HSDir client, HSDir cache evict, Intro service, Intro client, Rend service, Rend client)

Mike: Last Week: * Worked on #17857 and #22212. * Discussed padding statistics - I am not seeing this as urgent. * Reviewed #13605 (reduced exit policy option) This Week: * Mozilla all hands, all week...

asn: Last week: - Caught up with backlog that accumulated during meeting - Work on prop247 stuff. Started the simulator work: It can currently do a basic prop247 simulation and print out some useful output. - Worked with David on some prop224 stuff - Reviewed some prop224 code and other tickets This week: - Review prop224 groundwork #21979 - Continue prop247 simulation. This week I'll spend debugging, make the compromise adversary models and create some nice graphs. - Update prop224 spec wrt SRV / desc overlap behavior based on discussions with david and the current implementation. - Rewrite the overlap logic of prop224 to use the slot system instead of absolute human times. - Revisit #22006 based on nick/isis review. - Hopefully Write wilmington blog post if I get the time.

haxxpop: Last week: - Finished reviewing asn's client-side descriptor fetch code. He replied and I also did reply back :) - Read some lattice-based crypto (as a hobby) This week: - Review dgoulet's load and configure service code #21979 (with asn) - Maybe*, take over Fuzz v3 hidden services #21509 (if it's not done yet)

dgoulet: Last week: * DRL meeting on Mon, Tue and Wed. (Nick asks: any takeaway lessons?) * Code review on a couple of hidden service tickets. * We do have #21859 (prop224 e2e code) in needs_review now on Gitlab which is the first ticket in review for prop224 inclusion in 032. * Discussed some action items with asn on prop224 about some intro points engineering issues and overlap period logic that is out of sync in the proposal. This week: * Full throttle prop224 work with splitting the service branch in smaller ones for review and upstream merge. * Continuing and hopefully finishing the client implementation. * July is really our target for a minimally working prop224 for both our sponsors and our Defcon talk (early August). Thus, expect lots of work on that on my part.

nickm: Last week: * Thanks to ahf, helped diagnose big regression from prop140 (consensus diff) work: we weren't checking if-modified-since correctly any more! Ahf has a fix; testing again now. * Worked on compression issues that toralf found. * Reviewed lots of code. Merged a bunch. Continued bug triage. * Chased through some contacts to find clarity about copyright status for patches on old ticket from Access Labs. All's well. This week: * Pending isabela, send out notes on Who Works On What Between Now And September. * Circulate "supported platforms list" current draft from https://pad.riseup.net/p/QWpY4UYfAsaK , turn it into a wiki page, pending comment. Any comments? * Review more code * Fix pending 0.3.1.x bugs * Release another 0.3.1.x alpha * Write some stuff for 0.3.2.x * Work on or defer remaining 0.3.1.x tickets * More ticket triage on "unspecified" * Prepare for 0.3.2.x triage.

ahf:

Last week:

Sponsor 4: - Been working on Sponsor 4 measurements with Nick: Looks good for clients so far, but we have regressed badly for relays. We think we know what the primary cause is (see #22702). - Been working on a fix for bug #22702 (Never send a consensus which the downloader already has). - Wrote a script to collect directory measurement from Tor logs. Can be found in ahf/tor-sponsor4-compression on GL.com - Working with Nick on the initial results: data in https://people.torproject.org/~ahf/sponsor4/ - Code review: #22719, #22502 (and thus #22626 + #22628), #22629 Misc: - Code review: #3056

This week (ordered):

- Land fix(es) for #22702 after we have confirmed they work. - Land fix for the issue where a relay gets killed by the sandbox because we allocate a little bit over 16 MB memory. - Actually get around and finish the merge of prop #278 that I've kept postponing. - Help out with 0.3.1 issues - If time allows for it: write down a short text that tells the progress we have made with the sponsor 4 work (?)

catalyst: Last week: * Reviewed a lot of review-group-18 and 0.3.1 tickets * Progress on reviewing #7869 * Registered for oniongit This week: * Check #7869 test coverage * Investigate #20532 * Investigate more test-stem issues * Bug triage * Ping komlo about followup from Wilmington testing session * Follow up and review support person hiring stuff * Experiment more with oniongit

isabela: last week: - passed on next tasks to invoice for sponsorR to Brad - finally sent sponsor4 may report - working with tommy on modularization SOI - synced with Brad to get the info to build the spreadsheet for network team people's time allocation this week: - still waiting on one spreadsheet from brad to get back with nick on people's time allocation - hope to get that done this week - looking forward to finish a couple of pending tasks: update the brief for tor launcher automation and get an update on user growth strategy out to tor-internal - off on july 4th (national holiday) and july 5th-7th to get some personal stuff done - catch up with hiro on what we discussed in wilmington related to gitlab and trac

pastly: Last weekish: - I hope you like documentation. I wrote a bunch - I hope you like tests. Did those too Time weekish: - nickm asks: "how is the permission-to-release coming?"

- pastly says: no news. Was told it would take ~4 weeks about ~2.5 weeks ago

- but plans on sharing with dgoulet and anyone that asks nicely ASAP

- Finish fleshing out KIST tests. Main one remaining is for the scheduling loop - Once done fleshing out, will push to oniongit and ping dgoulet to make time for meeeeee
