Description of problem: ALPN (the alpn bind directive) can't be used in the haproxy.cfg file. Version-Release number of selected component (if applicable): rh-haproxy18-3.1-2.el7.x86_64 rh-haproxy18-haproxy-1.8.4-2.el7.x86_64 rh-haproxy18-runtime-3.1-2.el7.x86_64 How reproducible: Steps to Reproduce: 1. Configure a frontend like this: bind *:443 ssl crt cert.pem alpn h2,http/1.1 2. Restart the rh-haproxy18-haproxy service 3. Actual results: haproxy fails to start with the following error message: "'alpn' : library does not support TLS ALPN extension" Expected results: Additional info: rh-haproxy18 was built against OpenSSL 1.0.1e, which didn't support ALPN. OpenSSL 1.0.2k should be used here, as in the HAProxy 1.5.18 package.
