Tor 0.1.2.17

Posted on Monday, September 03 2007 @ 01:46:44 CEST by

Tor is a network of virtual tunnels that allows people and groups to improve their privacy and security on the Internet. It also enables software developers to create new communication tools with built-in privacy features. Tor provides the foundation for a range of applications that allow organizations and individuals to share information over public networks without compromising their privacy.

Tor 0.1.2.17 features a new Vidalia version in the Windows and OS X bundles. Vidalia 0.0.14 makes authentication required for the ControlPort in the default configuration, which addresses important security risks. Everybody who uses Vidalia (or another controller) should upgrade.

In addition, this Tor update fixes major load balancing problems with path selection, which should speed things up a lot once many people have upgraded.

Major bugfixes (security):
  • We removed support for the old (v0) control protocol. It has been deprecated since Tor 0.1.1.1-alpha, and keeping it secure has become more of a headache than it's worth.
Major bugfixes (load balancing):
  • When choosing nodes for non-guard positions, weight guards proportionally less, since they already have enough load. Patch from Mike Perry.
  • Raise the "max believable bandwidth" from 1.5MB/s to 10MB/s. This will allow fast Tor servers to get more attention.
  • When we're upgrading from an old Tor version, forget our current guards and pick new ones according to the new weightings. These three load balancing patches could raise effective network capacity by a factor of four. Thanks to Mike Perry for measurements.
Major bugfixes (stream expiration):
  • Expire not-yet-successful application streams in all cases if they've been around longer than SocksTimeout. Right now there are some cases where the stream will live forever, demanding a new circuit every 15 seconds. Fixes bug 454; reported by lodger.
Minor features (controller):
  • Add a PROTOCOLINFO controller command. Like AUTHENTICATE, it is valid before any authentication has been received. It tells a controller what kind of authentication is expected, and what protocol is spoken. Implements proposal 119.
Minor bugfixes (performance):
  • Save on most routerlist_assert_ok() calls in routerlist.c, thus greatly speeding up loading cached-routers from disk on startup.
  • Disable sentinel-based debugging for buffer code: we squashed all the bugs that this was supposed to detect a long time ago, and now its only effect is to change our buffer sizes from nice powers of two (which platform mallocs tend to like) to values slightly over powers of two (which make some platform mallocs sad).
Minor bugfixes (misc):
  • If exit bandwidth ever exceeds one third of total bandwidth, then use the correct formula to weight exit nodes when choosing paths. Based on patch from Mike Perry.
  • Choose perfectly fairly among routers when choosing by bandwidth and weighting by fraction of bandwidth provided by exits. Previously, we would choose with only approximate fairness, and correct ourselves if we ran off the end of the list.
  • If we require CookieAuthentication but we fail to write the cookie file, we would warn but not exit, and end up in a state where no controller could authenticate. Now we exit.
  • If we require CookieAuthentication, stop generating a new cookie every time we change any piece of our config.
  • Refuse to start with certain directory authority keys, and encourage people using them to stop.
  • Terminate multi-line control events properly. Original patch from tup.
  • Fix a minor memory leak when we fail to find enough suitable servers to choose a circuit.
  • Stop leaking part of the descriptor when we run into a particularly unparseable piece of it.
