requests to authorities fail due to a network error. Bug#1138 "When a Tor client starts up using a bridge, and UpdateBridgesFromAuthority is set, Tor will go to the authority first and look up the bridge by fingerprint. If the bridge authority is filtered, Tor will never notice that the bridge authority lookup failed. So it will never fall back." Add connection_dir_bridge_routerdesc_failed(), a function for unpacking the bridge information from a failed request, and ensure connection_dir_request_failed() calls it if the failed request was for a bridge descriptor. Test: 1. for ip in `grep -iR 'router ' cached-descriptors|cut -d ' ' -f 3`; do sudo iptables -A OUTPUT -p tcp -d $ip -j DROP; done 2. remove all files from user tor directory 3. Put the following in torrc: UseBridges 1 UpdateBridgesFromAuthority 1 Bridge 85.108.88.19:443 7E1B28DB47C175392A0E8E4A287C7CB8686575B7 4. Launch tor - it should fall back to downloading descriptors directly from the bridge. Initial patch reviewed and corrected by mingw-san.
