commit ce553d49821cf96666afe2380b2409329c71cd8b Author: Linus Nordberg linus@torproject.org Date: Wed Sep 19 17:15:40 2012 +0200
Have node_get_pref_orport() return an IPv6 OR port when UseBridges is set.
We used to never return an IPv6 address unless ClientUseIPv6 was set. We should allow clients running with bridges use IPv6 OR ports even without setting ClientUseIPv6. Configuring an IPv6 address in a Bridge line should imply that.
