Changes in version 0.3.2.1-alpha - 2017-09-18

  BLURB

  Tor 0.3.2.1-alpha is the first release in the 0.3.2.x series. It

  includes support for our next-generation ("v3") onion service

  protocol, and adds a new circuit scheduler for more responsive

  forwarding decisions from relays.  There are also numerous other

  small features and bugfixes here.

  Below are the changes since Tor 0.3.1.7.

  o Major bugfixes (usability, control port):

    - Report trusted clock skew indications as bootstrap errors, so

      controllers can more easily alert users. Fixes bug 23506; bugfix

      controllers can more easily alert users when their clocks are

      wrong. Fixes bug 23506; bugfix

      on 0.1.2.6-alpha.

  o Minor features (bug detection):

    - Log a warning message, with stack trace, for any attempt to call

      get_options() during option validation. Closes ticket 22281.

  o Minor features (client directory bandwidth tuning):

    - When downloading (micro)descriptors, don't split the list of

      descriptors into multiple requests unless there are at least 32

      descriptors that we want. Previously, we split at 4, not 32, which

      could lead to significant overhead in HTTP request size and

      degradation in compression performance. Closes ticket 23220.

  o Minor features (client):

    - You can now use Tor as a tunneled HTTP proxy: use the

      HTTPTunnelPort option to open a port that accepts HTTP CONNECT

      requests. Closes ticket 22407.

  o Minor features (client, entry guards):

    - Add an extra check to make sure that we always use the new guard

      selection code for picking our guards. Closes ticket 22779.

    - When downloading (micro)descriptors, don't split the list of

      descriptors into multiple requests unless there are at least 32

      descriptors that we want. Previously, we split at 4, not 32, which

      could lead to significant overhead in HTTP request size and

      degradation in compression performance. Closes ticket 23220.

  o Minor features (command line):

    - Add a new commandline option, --key-expiration, which prints when

    - Provide better error message for GETINFO desc/(id|name) when

      microdescriptors are in use and router descriptors are not

      fetched. Closes ticket 5847. Patch by Kevin Butler.

  o Minor features (control):

    - Add GETINFO desc/download-enabled and md/download-enabled, to

      inform the controller whether try to download router descriptors

      and microdescriptors respectively. Closes ticket 22684.

  o Minor features (controller):

    - Added new GETINFO targets ip-to-country/{ipv4,ipv6}-available, so

      controllers can tell whether the geoip databases are loaded.

      Closes ticket 23237.

      ticket 23054.

  o Minor features (testing):

    - The default chutney network tests now include tests for the v3

      hidden service design. Make sure you have the latest version of

      chutney if you want to run these. Closes ticket 22437.

    - Add a unit test to verify that we can parse a hardcoded v2 hidden

      service descriptor. Closes ticket 15554.

  o Minor bugfix (relay address resolution):

    - Avoid unnecessary calls to directory_fetches_from_authorities() on

      relays. This avoids spurious address resolutions and descriptor

      rebuilds. This is a mitigation for bug 21789. Fixes bug 23470;

      bugfix on in 0.2.8.1-alpha.

  o Minor bugfixes (certificate handling):

    - Fix a time handling bug in Tor certificates set to expire after

      the year 2106. Fixes bug 23055; bugfix on 0.3.0.1-alpha. Found by

      Coverity as CID 1415728.

  o Minor bugfixes (circuit logging):

    - torspec says hop counts are 1-based, so fix two log messages that

      mistakenly logged 0-based hop counts. Fixes bug 18982; bugfix on

      0.2.6.2-alpha and 0.2.4.5-alpha. Patch by teor. Credit to Xiaofan

      Li for reporting this issue.

  o Minor bugfixes (client, usability):

    - Refrain from needlessly rejecting SOCKS5-with-hostnames and

      SOCKS4a requests that contain IP address strings, even when

      Previously we used ntohs(), which happens to behave the same on

      all the platforms we support, but which isn't really correct.

      Fixes bug 23106; bugfix on 0.2.4.8-alpha.

    - Make the controller's write_escaped_data() function robust to

      extremely long inputs. Right now, it doesn't actually receive any

      extremely long inputs, so this is for defense in depth. Fixes bug

      19281; bugfix on 0.1.1.1-alpha. Reported by Guido Vranken.

  o Minor bugfixes (compilation):

    - Fix unused variable warnings in donna's Curve25519 SSE2 code.

      tor main loop callback that validates if we have an expired

      consensus. Fixes bug 23091; bugfix on 0.2.0.19-alpha.

  o Minor bugfixes (correctness, controller):

    - Make the controller's write_escaped_data() function robust to

      extremely long inputs. Right now, it doesn't actually receive any

      extremely long inputs, so this is for defense in depth. Fixes bug

      19281; bugfix on 0.1.1.1-alpha. Reported by Guido Vranken.

  o Minor bugfixes (crypto):

    - Properly detect and refuse to blind bad ed25519 keys. The key

      blinding code is currently unused, so this bug does not affect tor

      clients or services on the network. Fixes bug 22746; bugfix

      on 0.2.6.1-alpha.

  o Minor bugfixes (directories):

  o Minor bugfixes (directory protocol):

    - Directory servers now include a "Date:" http header for response

      codes other than 200. Clients starting with a skewed clock and a

      recent consensus were getting "304 Not modified" responses from

      directory authorities, so without a Date header the client would

      never hear about a wrong clock. Fixes bug 23499; bugfix

      on 0.0.8rc1.

  o Minor bugfixes (directory downloads):

    - Make clients wait for 6 seconds before trying to download their

      consensus from an authority. Fixes bug 17750; bugfix

      on 0.2.8.1-alpha.

      actual name of the user owning the directory. Previously, we'd log

      the name of the process owner twice. Fixes bug 23487; bugfix

      on 0.2.9.1-alpha.

    - torspec says hop counts are 1-based, so fix two log messages that

      mistakenly logged 0-based hop counts. Fixes bug 18982; bugfix on

      0.2.6.2-alpha and 0.2.4.5-alpha. Patch by teor. Credit to Xiaofan

      Li for reporting this issue.

  o Minor bugfixes (portability):

    - Stop using the PATH_MAX variable. The variable is not defined in

    - When uploading our descriptor for the first time after startup,

      report the reason for uploading as "Tor just started" rather than

      leaving it blank. Fixes bug 22885; bugfix on 0.2.3.4-alpha.

    - Avoid unnecessary calls to directory_fetches_from_authorities() on

      relays. This avoids spurious address resolutions and descriptor

      rebuilds. This is a mitigation for bug 21789. Fixes bug 23470;

      bugfix on in 0.2.8.1-alpha.

  o Minor bugfixes (test):

  o Minor bugfixes (tests):

    - Fix a broken unit test for the OutboundAddress option: the parsing

      function was never returning an error on failure. Fixes bug 23366;

      bugfix on 0.3.0.3-alpha.

  o Minor bugfixes (tests):

    - Fix a signed-integer overflow in the unit tests for

      dir/download_status_random_backoff, which was untriggered until we

      fixed bug 17750. Fixes bug 22924; bugfix on 0.2.9.1-alpha.

    - The controller API no longer includes an AUTHDIR_NEWDESCS event:

      nobody was using it any longer. Closes ticket 22377.

  o Testing:

    - The default chutney network tests now include tests for the v3

      hidden service design. Make sure you have the latest version of

      chutney if you want to run these. Closes ticket 22437.
