I have looked at libressl source code and it does not look like the no_application_protocol(120) is implemented. Openssl also does not yet support this portion of the ALPN spec ( https://tools.ietf.org/html/rfc7301#section-3.2) but it seems the issue is now being reprioritized (https://github.com/openssl/openssl/issues/188). It seems like libressl is API compatible with OpenSSL's ALPN offerings so I have the following questions:
1. Is there an open issue to support no_application_protocol(120) in libressl? 2. How are "new features" added to openssl coordinated with libressl, and what is the libressl API compatibility philosophy for new OpenSSL features or API additions? Thanks, Scott
