Fixed In Version: python-cryptography-2.1.4-1.el7ost
Doc Type: Release Note
Doc Text:
Since version 2.1, python-cryptography checks that the CNS Names used in certificates are compliant with IDN standards. If the found names do not follow this specification, cryptography will fail to validate the certificate and different errors may be found when using OpenStack command line interface or in OpenStack service logs.

Description Carlos Goncalves 2018-03-15 14:55:47 UTC
+++ This bug was initially created as a clone of Bug #1553517 +++

Description of problem:

Octavia requires python2-cryptography!=2.0,>=1.9 [1] and is synced with global-requirement.txt [2]. CentOS7 provides python2-cryptography-1.7.2-1.el7 which is not good enough and throws exceptions on load balancer create in Octavia:

2018-03-08 23:45:46.453 24634 ERROR octavia.controller.worker.controller_worker AttributeError: 'X509' object has no attribute 'to_cryptography'

Could we promote python2-cryptography-2.1.4 from Fedora [3]? There might be some considerations to be made first, i.e. bump of openssl and pyopenssl versions?

--- Additional comment from Carlos Goncalves on 2018-03-15 07:02:17 EDT ---

python-cryptography>=1.9 is not good enough as recently discovered with a new gate using lower-constraints [1]. Octavia requires python-cryptography>=2.1.

Version bump being requested upstream for global-requirements.txt and lower-constraints.txt in [2].

RDO already bumped the library, waiting for an import.
