Subject: Allow RO connections to interface udev backend
X-Git-Tag: CVE-2013-2218~12
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=027a7707bea5ba455212715278e3ae486f97eacb;p=thirdparty%2Flibvirt.git

Allow RO connections to interface udev backend

The udev based interface backend did not allow querying data over a
read-only connection which is different than how the netcf backend
operates. This brings the behavior inline with the default, netcf
backend.
