Subject: [PULL 36/36] iotests/162: Fix for newer Linux 5.3+
Date: Thu, 10 Oct 2019 13:43:00 +0200
Message-ID: <20191010114300.7746-37-mreitz@redhat.com> (raw)
In-Reply-To: <20191010114300.7746-1-mreitz@redhat.com>

Linux 5.3 has made 0.0.0.0/8 a working IPv4 subnet.  As such, "42" is
now a valid host, and the connection to it will (hopefully) time out
over a long period rather than quickly return with EINVAL.

So let us use a negative integer for testing that NBD will not crash
when it receives integer hosts.  This way, the connection will again
fail quickly and reliably.
