Description Joe Orton 2016-04-15 11:17:50 UTC

Description of problem:
The version of OpenSSL in RHEL 7 currently only supports NPN.  The HTTP/2 community is standardising around ALPN, which is only supported in OpenSSL 1.0.2.

As a result, the RHSCL httpd24 will not be interoperable with newer HTTP/2 clients attempting to upgrade TLS connections.

Version-Release number of selected component (if applicable):
httpd24-httpd-2.4.18-9

How reproducible:
always

Comment 11 Jan Houska 2017-10-05 10:11:53 UTC

Verified 
test /CoreOS/httpd/mod_http2/smoke is  working on RHEL-7.4 on architectures  1486372 with no problem. The test run on architecture aarch64 on RHEL-7.4 revealed known bug BZ#1429006.  It seems that this bug is not caused by by change to ALPN protocol support because it appearing on RHEL-7.3 and earlier.
