Norman Maurer d0bfbdde8e Detect truncated responses caused by EDNS0 and MTU miss-match (#9468) ... Motivation: It is possible that the user uses a too big EDNS0 setting for the MTU and so we may receive a truncated datagram packet. In this case we should try to detect this and retry via TCP if possible Modifications: - Fix detecting of incomplete records - Mark response as truncated if we did not consume the whole packet - Add unit test Result: Fixes https://github.com/netty/netty/issues/9365		2019-08-17 09:58:22 +02:00
