** Description changed: + [Impact] + + Security Group rules using a remote address group are now supported on older + versions of Neutron, back to Yoga. + + [Test Case] + + Assuming neutron is configured to use the iptables firewall driver, you should + now be able to add a security group rule specifying a --remote-address-group + parameter where previously it would fail. + + [Where problems could occur] + + Problem would occur when adding a security group rule with --remote- + address-group paremeter. + + [Others] + + == ORIGINAL DESCRIPTION == + High level description - The Neutron API allows operators to configure remote address groups [1], however the OVSHybridIptablesFirewallDriver and IptablesFirewallDriver do not implement these remote group restrictions. When configuring security group rules with remote address groups, connections get enabled based on other rule parameters, ignoring the configured remote address group restrictions. This behaviour undocumented, and may lead to more-open-than-configured network access. Background - Remote address groups enable specifying rules that target many CIDRs efficiently. In line with the remote security group support, this should be implemented through the use of hashed ipsets in case of the IptablesFirewallDriver. Pre-conditions - * Using OVSHybridIptablesFirewallDriver or IptablesFirewallDriver * Configured remote Address Groups. Version - All OpenStack versions with remote address group support are impacted. We noticed it on 2024.1. [1] https://docs.openstack.org/python- openstackclient/latest/cli/command-objects/address-group.html
