Title:
arp spoofing protection flow install failed
Status in neutron:
Fix Released
Bug description:
Now ovs-agent failed to install arp spoofing protection flow for new VMs,
because it will firstly install arp spoofing protection flow in funstion
'treat_devices_added_or_updated':
def treat_devices_added_or_updated(self, devices, ovs_restarted):
.....
.....
if self.prevent_arp_spoofing:
self.setup_arp_spoofing_protection(self.int_br, port, details)
but then in function '_bind_devices', it will clear all flows for this
new port, so the arp spoofing protection flow is also be clean
def _bind_devices(self, need_binding_ports):
.....
....
if cur_tag != lvm.vlan:
self.int_br.set_db_attribute(
"Port", port.port_name, "tag", lvm.vlan)
if port.ofport != -1:
# NOTE(yamamoto): Remove possible drop_port flow
# installed by port_dead.
self.int_br.delete_flows(in_port=port.ofport)
