Hi guys, We are having an issue when trying to json.dumps() an object that contains an IPNetwork. oslo.serialization.jsonutils.to_primitive() tries to include every single ip address in the ip network in the dumped json. This of course creates issues with an ipv6 network. You guys fixed this in https://review.openstack.org/#/c/475052/ , but only for master / 2.19.0 upwards. Is there a way to backport this to newton/ocata releases as well? I am more than happy to do the heavy lifting on this, but wanted to check with you guys before I start submitting anything :) Kind regards, Tom Stappaerts Nokia OpenStack software engineer -------------- next part -------------- An HTML attachment was scrubbed...
