Description Yogita 2017-11-03 07:45:32 UTC

Description of problem:

Customer wants HA-Proxy(haproxy-1.5.18-6.el7.x86_64) RPM built against the current version of OpenSSL,openssl-1.0.2k-8.

Version-Release number of selected component (if applicable):
haproxy-1.5.18-6.el7.x86_64
openssl-1.0.2k-8.el7.x86_64

How reproducible:

haproxy-1.5.18-6 RPM has been built against an older version of OpenSSL (OpenSSL 1.0.1e-fips):

> # openssl version
> OpenSSL 1.0.2k-fips  26 Jan 2017
> 
> # haproxy -vv
> ...
> Built with OpenSSL version : OpenSSL 1.0.1e-fips 11 Feb 2013

The OpenSSL 1.0.1x-branch does not provide ALPN whilst the 1.0.2x branch does.  Customer require HA-Proxy to be built against the 1.0.2x branch so that HA-Proxy will support ALPN.  ALPN is now required for HTTP2 Web services as most major browsers are removing support for SPDY and/or NPN in favour of ALPN.  This was a major problem in RHEL 7.3 and previous as the 1.0.1x-branch of OpenSSL provided did not offer ALPN but with RHEL 7.4 now providing openssl-1.0.2x:

"The OpenSSL update includes ... support for ... Application-Layer Protocol Negotiation (ALPN). "

[ https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/7/html/7.4_release_notes/chap-red_hat_enterprise_linux-7.4_release_notes-overview ]

As a starting point this is great but Customer still cannot process HTTP2 ALPN requests via HA-Proxy as current haproxy-1.5.18-6 has been built against the older branch of OpenSSL - against OpenSSL 1.0.1e-fips - and therefore has no ALPN support.

Comment 3 Ryan O'Hara 2017-11-28 22:28:04 UTC

This just requires a rebuild. At the moment, haproxy is not scheduled to get an update in RHEL7.5, but I will try to squeeze it in.

Comment 4 Ryan O'Hara 2017-11-30 15:23:03 UTC

Quick test.

# rpm -q haproxy
haproxy-1.5.18-6.el7.x86_64

# haproxy -vv|grep OpenSSL
Built with OpenSSL version : OpenSSL 1.0.1e-fips 11 Feb 2013
Running on OpenSSL version : OpenSSL 1.0.1e-fips 11 Feb 2013
OpenSSL library supports TLS extensions : yes
OpenSSL library supports SNI : yes
OpenSSL library supports prefer-server-ciphers : yes

New build.

# rpm -q haproxy
haproxy-1.5.18-7.el7.x86_64

# haproxy -vv|grep OpenSSL
Built with OpenSSL version : OpenSSL 1.0.2k-fips  26 Jan 2017
