[tor/master] clients now send correct address for rendezvous point
by nickm＠torproject.org 16 Sep '14

commit 0c3b3650aa831183c76b044466e89eaee36d5684 Author: Roger Dingledine <arma(a)torproject.org> Date: Sat Sep 13 21:49:37 2014 -0400 clients now send correct address for rendezvous point Clients now send the correct address for their chosen rendezvous point when trying to access a hidden service. They used to send the wrong address, which would still work some of the time because they also sent the identity digest of the rendezvous point, and if the hidden service happened to try connecting to the rendezvous point from a relay that already had a connection open to it, the relay would reuse that connection. Now connections to hidden services should be more robust and faster. Also, this bug meant that clients were leaking to the hidden service whether they were on a little-endian (common) or big-endian (rare) system, which for some users might have reduced their anonymity.
