Description of problem:

Request to backport upstream fix to Juno
https://bugs.launchpad.net/neutron/+bug/1460741

SCTP association can't be etablished because security groups set the following rule :
DROP all -- any any anywhere anywhere state INVALID 

When we delete this rule the association is etablished.


Version-Release number of selected component (if applicable):

use rhel-osp-installer 0.5.7-3 on a  Red Hat Enterprise Linux 7.1 virtual machine in order to deploy Openstack controller and compute on UCSB-B200-M4 blades.

Neutron's rpm used on our controllers are :
python-neutronclient-2.3.9-1.el7ost.noarch
openstack-neutron-common-2014.2.3-33.el7ost.noarch
openstack-neutron-openvswitch-2014.2.3-33.el7ost.noarch
openstack-neutron-ml2-2014.2.3-33.el7ost.noarch
openstack-neutron-cisco-2014.2.3-33.el7ost.noarch
openstack-neutron-2014.2.3-33.el7ost.noarch
python-neutron-2014.2.3-33.el7ost.noarch

Neutron's rpm used on our compute are :
openstack-neutron-2014.2.3-33.el7ost.noarch
openstack-neutron-openvswitch-2014.2.3-33.el7ost.noarch
python-neutronclient-2.3.9-1.el7ost.noarch
openstack-neutron-common-2014.2.3-33.el7ost.noarch
python-neutron-2014.2.3-33.el7ost.noarch


Additional info:
If we delete the DROP rules, the behavior occur at every security rules modification.

Comment 3 Bernard Cafarelli 2017-01-17 13:27:16 UTC
Can you confirm the versions? The backport already is in OSP 6, bug #1268413
The version that first included the fix is openstack-neutron-2014.2.3-23.el7ost so 2014.2.3-33.el7ost should work (and still has the patch)

Comment 6 Scott Lewis 2018-02-22 20:35:43 UTC
OSP6 has been retired, and will not receive further updates. See https://access.redhat.com/support/policy/updates/openstack/platform/ for details.
