Bug #11739

OpenSSL::SSL::SSLServer doesn't negotiate ECDHE-* ciphersuites

Description

I'm trying to configure an instance of OpenSSL::SSL::SSLServer that supports Elliptic curve Diffie–Hellman. No matter what combination of Ruby and OpenSSL versions I try the negotiation with the client fails.

Proof of concept:
https://gist.github.com/brandonweeks/e26414cc1e9eea9453a8

Then run:

openssl s_client -connect localhost:8443

Also attaching a pcap file of the failed handshake.

ext/openssl didn't support ephemeral ECDH in server mode up until Ruby 2.3 (Feature #11356).
