Subject: rec: Set the Protocol Buffer 'inBytes' field for zero-length messages
X-Git-Tag: rec-4.5.0-alpha1~35^2
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=c4de50c91d1ac5955abd7fb1452b81e3ca579b7f;p=thirdparty%2Fpdns.git

rec: Set the Protocol Buffer 'inBytes' field for zero-length messages

Th existing Protocol Buffer code used to do that, so existing receivers
might expect that field to be present.
