It also forces the addition of the 'is_garp_rarp_enabled' flag and creating 'garp_rarp_data' structures for cases in which we don't really need them (we send no garps/rarps). What if we do this in a different way? In binding.c we set port_binding.up to "false" whenever ports are removed. Should we cleanup stale FDB entries there instead? There are two places where we do that: binding_lport_set_down() port_binding_set_down() What do you think? Here, we are also trying to address the scenario where the vif port link state goes down and not only handle scenarios such as port removal or iface-id detachment. For example, when a VM migration is completed and the hypervisor is in process of removing the VM on the source side, the VIF port state goes down. We need to detect the port link state down event and delete the FDB entries as soon as possible to reduce traffic loss. We clubbed it with garp_rarp code because this code is already tracking the VLAN bridged ports. Sorry but I still don't really understand how you're addressing the VIF port link going down. Do you mind detailing that part, please? Would it make sense to add a system test (system-ovn.at<http://system-ovn.at/>) for this case too then? I still think we should try to not overload the semantics of the garp/rarp code in pinctrl.c but maybe I'm misunderstanding the situation. Thanks, Dumitru Sometime back as part of the commit d34509941ea6c9b5e5847a9f96ea5f235f56cccd we had registered for interface link-state events in ovn-controller. Hence, in case of a link state change, send_garp_rarp_prepare() is triggered which gets the latest active ports via get_localnet_vifs_l3gwports(), and compares with the stored set of ports in the send_garp_rarp_data and takes action (send/delete) accordingly. We planned to reuse these garp_rarp data structures to avoid a lot of code duplication. Presently we have added a test case which is closely simulating a link down event, if not exactly. "test x`ovn-nbctl lsp-get-up vif0` = xdown” Perhaps, I will check in system-on.at<http://system-on.at/> if there is a better way. Do let me know your views or if you have any further queries.
