Bug 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.
