From ff9bdbd56ffdc4d91da377ca5e1624b58aeaab8e Mon Sep 17 00:00:00 2001 From: Nick Mathewson Date: Thu, 17 Jan 2013 18:07:36 -0500 Subject: 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. --- doc/tor.1.txt | 8 ++++++++ 1 file changed, 8 insertions(+) (limited to 'doc/tor.1.txt') diff --git a/doc/tor.1.txt b/doc/tor.1.txt index 40cf66dbc..3b13a6180 100644 --- a/doc/tor.1.txt +++ b/doc/tor.1.txt @@ -689,6 +689,14 @@ The following options are useful only for clients (that is, if node listed in ExcludeNodes is automatically considered to be part of this list too.
