commit 834654f145cc1205e20cf5f07a37bef2e11252ce Author: Nick Mathewson nickm@torproject.org Date: Tue May 15 09:41:45 2012 -0400

Make all begindir or one-hop circuits internal

This solves bug 5283, where client traffic could get sent over the same circuit as an anonymized connection to a directory, even if that circuit used an exit node unsuitable for clients. By marking the directory connection as needs_internal, we ensure that the (non-internal!) client-traffic connection won't be sent over the same circuit. --- src/or/circuituse.c | 8 +++++++- 1 files changed, 7 insertions(+), 1 deletions(-)
