o Code simplification and refactoring:
|
||||
- Rework Tor SOCKS server code to use Trunnel and benefit from
|
||||
autogenerated functions for parsing and generating SOCKS wire
|
||||
format. New implementation is cleaner, more maintainable and
|
||||
should be less prone to heartbleed-style vulnerabilities.
|
||||
Implements a significant fraction of ticket 3569.
