Comment:
Please see my branch bug19608 on https://github.com/teor2345/tor.git
It fixes this issue by checking routerstatus reachability based only on
the addresses in the routerstatus. (We were checking the node, but this
causes issues when there is no node, and it's inaccurate anyway, as the
connection address is taken from the routerstatus, not the node.)
I've tested this on an IPv6-only BSD box, and it works with and without
bridges, with and without microdescriptors.
This could end up overloading the IPv6 fallbacks if we have lots of
IPv6-only clients. I split that issue off into #19610, and stuck it into
0.3.0.
