GSoC: Ahmia.fi - Search Engine for Hidden Services
by Juha Nurmi 12 May '14

12 May '14

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, I'm a student who is starting to work with ahmia.fi search engine as a part of Google Summer of Code. :) The proposal is online here https://ahmia.fi/gsoc/ In practise, I have now time and funding to develop my search engine. George is my primary mentor and Moritz the backup mentor. Today, I will submit all the required documents (the tax forms etc.) to Google. After that, I think I will speed up with code base in the GitHub :) Cheers, Juha -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 Comment: Using GnuPG with Thunderbird - http://www.enigmail.net/ iQEcBAEBAgAGBQJTViWUAAoJELGTs54GL8vAuC8H/jSdgBCRQM/3l3mX5Uig9fgM wacPsxm6RJd3Sw+JJpYgoRP1nDqI513haP4Z6s//tR3Vn5RyQ/u7ik3QdFEVKbJD KqnQ4Eaf5hT4xsJwBXZIjzW6uhbYaq1GmUJi4eaglwUrgIgJrHzDbOz/p8q71O1z rLnrS1vrsvMzY4rU0dRe1/S9LyPWTUAfpVMINa54RPmNjMzrTT/WUnlcQWo9cY3a SRrT2MVz5nwBEXJuhZUmC3L6XLL8RX2TgzGwVyYOUfMlNuZdcSaOOTvF7gKVZVZQ hGhr/V40iNm5BOAcQ2TVaxuR5HjxSFWUp15T8ux+xxyN/Yp9EeaDjsAsTVegq0w= =QMfR -----END PGP SIGNATURE-----

BridgeDB's email server rewrite; NEED CODE REVIEW
by isis 12 May '14

12 May '14

Hi everyone! If someone who is comfortable with Twisted Python and SMTP could look over my rewrite of BridgeDB's email servers, that would be great! The servers currently "online" (they are mostly down, and they keep falling over) had so many bugs that I spent a week and a half trying to stabilise them. Then I spent a mere day and a half rewriting them completely, fixing the following bugs: #5463 #7547 #7550 #8241 #11475 #11753, among others. The relevant branch is my `fix/5463-7547-7550-8241-11475-11753-email-rewrite` branch, [0] and most of the new code can be found in the `lib/bridgedb/email` tree. [1] The relevant ticket for providing feedback would be #5463, where most of the discussion is happening. [2] Since I've already waited about a week for review, and the servers are currently broken and people are complaining at me a lot, I'm giving y'all 48 hours to speak up, else forever hold your pisces. Thanks in advance for reviewing! :) [0]: https://gitweb.torproject.org/user/isis/bridgedb.git/shortlog/refs/heads/fi… [1]: https://gitweb.torproject.org/user/isis/bridgedb.git/tree/refs/heads/fix/54… [2]: https://trac.torproject.org/projects/tor/ticket/5463 -- ♥Ⓐ isis agora lovecruft _________________________________________________________ GPG: 4096R/A3ADB67A2CDB8B35 Current Keys: https://blog.patternsinthevoid.net/isis.txt

fteproxy 0.2.14 released (resolves ticket #11629)
by Kevin P Dyer 11 May '14

11 May '14

Hi George, I've released version 0.2.14 of fteproxy [1], with corresponding changes [2] to the Tor Browser. This release addresses ticket #11629 [3], thanks to Yawning's patch [6]. My changes [2] to the tor-browser-bundle include the following: - Updated fteproxy to 0.2.14 - Updated obfsproxy to 0.2.9 - Changed versions.nightly tag to "master" for fteproxy and obfsproxy - The fte python module (the FTE cryptographic primitive) is now a separate project [4,5] as of fteproxy 0.2.14. This is reflected in the build process. I've tested these changes and they resolve #11629 on Windows/LInux/OSX. Would be great if you could test this, too. As discussed in the PT meeting on Friday, from 0.2.14 I will treat fteproxy master as stable and perform all development on a separate branch. Changes that break the tor-browser-bundle will be pushed to master only when there is a correspond tor-browser update. Hopefully, this should resolve the issue of fteproxy breaking the nightly TBB build. Thanks! -Kevin [1] https://github.com/kpdyer/fteproxy/releases/tag/0.2.14 [2] https://github.com/kpdyer/tor-browser-bundle [3] https://trac.torproject.org/projects/tor/ticket/11629 [4] https://pypi.python.org/pypi/fte [5] https://github.com/kpdyer/libfte [6] https://github.com/kpdyer/fteproxy/commit/0f7f68d01b133f7d61bd3ad239af89021…

test_status.c on MSVC
by Gisle Vanem 10 May '14

10 May '14

The test/test_status.c fails to compile using MSVC since the statement: log_global_min_severity_ = LOG_DEBUG; Ref. https://gitweb.torproject.org/tor.git/commit/3ce3984772b673b82a87aded1bc8a1… This 'log_global_min_severity_' variable should not be only for GNU-C? So this patch fixed it for MSVC: --- common/torlog.h.orig 2014-05-09 23:20:36 +0000 +++ common/torlog.h 2014-05-10 13:06:15 +0000 @@ -156,9 +156,9 @@ int tor_log_get_sigsafe_err_fds(const int **out); void tor_log_update_sigsafe_err_fds(void); -#if defined(__GNUC__) || defined(RUNNING_DOXYGEN) extern int log_global_min_severity_; +#if defined(__GNUC__) || defined(RUNNING_DOXYGEN) void log_fn_(int severity, log_domain_mask_t domain, const char *funcname, const char *format, ...)

TBB: default setting for security.tls.version.max prevents use of TLS 1.2
by Maciej Soltysiak 09 May '14

09 May '14

Hi, It's my first post in tor ml, hope it's the right place to write this. I am using the latest TBB. The default setting for the maximum version of TLS (comming from Firefox) is TLS 1.0 (security.tls.version.max = 1) ssllabs.com tests would confirm the result: TLS 1.2 No TLS 1.1 No TLS 1.0 Yes SSL 3 Yes SSL 2 No That's not very good, considering we're aiming for the top notch security here. When I set security.tls.version.max = 3 (meaning try to negotate TLS 1.2 first) I got: TLS 1.2 Yes TLS 1.1 Yes TLS 1.0 Yes SSL 3 Yes SSL 2 No Test it out yourselves. Anyway, I would like to propose we make TBB have security.tls.vesion.max=3 to make use of TLS 1.2 Best regards, Maciej Soltysiak
