+ Many modern operating systems give a running program the ability to drop
+ capabilities that it no longer needs, and other ways for a program to run
+ pieces of itself in a sandbox with diminished privileges.
+ </p>
+
+ <p>
+ We'd like to do this with Tor, to improve its resistance to attacks. The
+ easiest areas to address would be on systems like <a
+ href="https://lwn.net/Articles/475361/";>recent Linux kernels</a> that make
+ it easy to drop or restrict the set of syscalls that a program can invoke.
+ That's a great project, but probably not big enough for an internship just
+ on its own. For that, we'd want to make progress on at least multiple
+ platforms, or look into refactoring Tor into pieces that need more
+ privileges and pieces that don't with an eye towards sandboxing them
+ differently.

+ The Tor code is almost 10 years old in places, and we haven't always had
+ enough time or wisdom to write things as well as we could have. Our unit
+ test coverage is shamefully low, and the dependency graph of our modules is
+ shamefully convoluted . We could use refactoring and unit tests! Please
+ look through the Tor source code and look for ugly or tricky code or
+ dependencies -- the uglier and trickier the better -- and think about how
+ you could make the code look better, read better, and (subject to testing)
+ work better.
+ </p>
+
+ <p>
+ If this is for a fun side-project, it would be great for you to work on
+ anything that can be made better and more tested. For an internship-level
+ position, we'd hope that you could find a number of particularly tricky or
+ knotty piece of the code to clean up, and aim for resolving the ugliest
+ problems, not necessarily the easiest.
+ </p>
+
+ <p>
+ For a big project here, it would be great to pick one of the major
+ "submodules" of Tor -- path selection, node discovery, directory authority
+ operations, directory service -- and refactor its interface completely, to
+ minify and codify its points of contact with the rest of Tor.

+ We have an open proposal for a way to make Tor bridges avoid censorship by
+ impersonating an HTTPS server. Specifically, we need to hack some popular
+ SSL "reverse proxy" (your choice) so that it relays regular web connections
+ to an HTTP server, but certain connections to a local Tor process. <a
+ href="https://gitweb.torproject.org/torspec.git/blob_plain/HEAD:/proposals/203-https-frontend.txt";>Proposal
+ 203</a> has a general design sketch.

+ <p>
+ We have a little Python tool called <a
+ href="https://gitweb.torproject.org/nickm/chutney.git";>Chutney</a> for
+ making small local test networks. It's small, not widely used, and not as
+ automated as it could be.
+ </p>
+
+ <p>
+ It would be great to see chutney extended and a set of supporting tests
+ built to the point where we could use Chutney to exercise various Tor
+ features as an automated integration test.
