> Fix For: 1.0.0

>
> Our SSL certificate validation currently assumes that the host (on connect
> and on accept) does have a valid hostname. This however is not true for all
> environments.
> {{process::network::openssl::verify}} currently only allows the validation of
> a certificate against a hostname.
> See
> https://github.com/apache/mesos/blob/08866edd8a71d12f87f4f4dbefa292729efbf6ae/3rdparty/libprocess/src/openssl.cpp#L546
> RFC2818 however says that it should be perfectly valid to validate a
> certificate based on the IP address.
> See https://tools.ietf.org/html/rfc2818
> {noformat}
> In some cases, the URI is specified as an IP address rather than a
> hostname. In this case, the iPAddress subjectAltName must be present
> in the certificate and must exactly match the IP in the URI.
