Hi, I hope this is the right place for it:
for an upcoming customer project I need ALPN/NPN support in apache 2.4.x. There is a (reopened) ticket with patch for this (https://issues.apache.org/bugzilla/show_bug.cgi?id=52210) that was started on 2.2.x The patch is applied with slight variation to trunk, but not in 2.4. For my own work, I made a patch of your NPN trunk changes alone, applicable to the 2.4.x mod_ssl sources. If interested, I am happy to supply this to you. Getting a 2.4 release with this in it, would make my work easier. As you can read on the discussion on the ticket and are probably aware of, ALPN replaces NPN and NPN will go away. Better sooner than later. However that should not really matter to modules using mod_ssl, as functionality and negotiated protocol names stay the same. So, ALPN can replace NPN inside mod_ssl without callbacks being affected. I plan to enhance the NPN patch for mod_ssl with ALPN support, testing the openssl capabilities in a similar way. That will result in mod_ssl using ALPN instead of NPN when the underlying openssl supported it (compile time) and use NPN otherwise (if there). This will allow 2.4 modules to start using protocol negotiation while the underlying mechanism migrates. If interested, I will supply the ALPN patch to you. If you have opinions about changing the name of the callback from "modssl_register_npn" to "modssl_register_alpn", please let me know. Cheers, Stefan PS. In discussion with openssl developer Rich Salz, I learned that release plans are as follows: - ALPN support is in 1.0.2, currently beta, to become full release in "one or two weeks" - ALPN support is not in 1.0.1, backport *may* be possible, if someone shows real interest PPS. Rich also mentioned that they are working with libre on a common, simplified API. If someone from apache httpd is interested to learn more about this, he should contact him. Might be productive to have also the user side looking into this. <green/>bytes GmbH Hafenweg 16, 48155 Münster, Germany Phone: +49 251 2807760. Amtsgericht Münster: HRB5782
