Subject: Have eventdns set the "truncated" bit correctly.
X-Git-Tag: tor-0.2.1.17-rc~11
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=7ce767181f42879d48737ba69c4ce99963d76d9f;p=thirdparty%2Ftor.git

Have eventdns set the "truncated" bit correctly.

Fixed bug 1022; This isn't actually a live bug in Tor, since in Tor
we never generate large DNS replies.
