Most users won't even know what string from this to google on to find
out what this is all about:
Jul 03 13:57:20 jidanni7 kernel: ------------[ cut here ]------------
Jul 03 13:57:20 jidanni7 kernel: recvmsg bug 2: copied 73BCB6CD seq 70F17CBE rcvnxt 73BCB9AA fl 0
Jul 03 13:57:20 jidanni7 kernel: WARNING: CPU: 2 PID: 1501 at /build/linux-uwVqDp/linux-4.16.16/net/ipv4/tcp.c:1881 tcp_recvmsg+0x649/0xb90
Jul 03 13:57:20 jidanni7 kernel: Modules linked in: nft_r...
So please make clearer messages.

OK, but there should be something telling the user one way or the other
that the following is an error / bug message from the Linux kernel, (and
thus not some random program that the user installed), from the
component net/ipv4/tcp.c, and represents some condition that was
unexpected and should be reported to ... or is the user's own fault ...
and if he wants to google about it he is best to use ...
