There is an option for race conditions on the "is_provider_network" checkings when doing expose/withdraw actions. This happens when by the time the action checking if the port associated datapath is a provider network, the network associated to the datapath has been deleted, throwing an exception at ovsdbapp level -- ValueError This case needs to be handled so that if it happens on a expose action, the processing is not continued (there is no need to expose an IP on a subnet that is removed, as the port will be removed too). If by contract it happens on a withdraw, there are some cases where it can be dismiss too, as other associated event will take care of them (such as the case for OVN_LBs or for remote IPs), but needs to be handled in others (such as IPs on the provider network). This patch is adding this logic to the driver. Change-Id: Ia5d832499d70ebae2aa413b2028232d745d9131f
