OpenStack Networking (Neutron)
00298fe6e8
When add allowed-address-pair 0.0.0.0/0 to one port, it will unexpectedly open all others' protocol under same security group. IPv6 has the same problem. The root cause is the openflow rules calculation of the security group, it will unexpectedly allow all IP(4&6) traffic to get through. For openvswitch openflow firewall, this patch adds a source mac address match for the allowed-address-pair which has prefix lenght 0, that means all ethernet packets from this mac will be accepted. It exactly will meet the request of accepting any IP address from the configured VM. Test result shows that the remote security group and allowed address pair works: 1. Port has 0.0.0.0/0 allowed-address-pair clould send any IP (src) packet out. 2. Port has x.x.x.x/y allowed-address-pair could be accepted for those VMs under same security group. 3. Ports under same network can reach each other (remote security group). 4. Protocol port number could be accessed only when there has related rule.
