[tor/master] When excluding nodes by country, exclude {??} and {A1} too

commit ff9bdbd56ffdc4d91da377ca5e1624b58aeaab8e Author: Nick Mathewson <nickm(a)torproject.org> Date: Thu Jan 17 18:07:36 2013 -0500 When excluding nodes by country, exclude {??} and {A1} too This is ticket 7706, reported by "bugcatcher." The rationale here is that if somebody says 'ExcludeNodes {tv}', then they probably don't just want to block definitely Tuvaluan nodes: they also want to block nodes that have unknown country, since for all they know such nodes are also in Tuvalu. This behavior is controlled by a new GeoIPExcludeUnknown autobool option. With the default (auto) setting, we exclude ?? and A1 if any country is excluded. If the option is 1, we add ?? and A1 unconditionally; if the option is 0, we never add them. (Right now our geoip file doesn't actually seem to include A1: I'm including it here in case it comes back.) This feature only takes effect if you have a GeoIP file. Otherwise you'd be excluding every node. --- changes/feature7706 | 9 +++++++++ doc/tor.1.txt | 8 ++++++++ src/or/config.c | 13 +++++++++++++ src/or/or.h | 5 +++++ src/or/routerset.c | 39 +++++++++++++++++++++++++++++++++++++++ src/or/routerset.h | 1 + 6 files changed, 75 insertions(+), 0 deletions(-) diff --git a/changes/feature7706 b/changes/feature7706 new file mode 100644 index 0000000..69b91a6 --- /dev/null +++ b/changes/feature7706 @@ -0,0 +1,9 @@ + o Minor features: + - When any country code is listed in ExcludeNodes or + ExcludeExitNodes, and we have GeoIP information, also exclude + all nodes with unknown countries ({??} and {A1} if + present).
