The UUID generator keeps an arbitrary number of MAC addresses, under the assumption that they are rarely removed (= uuid_ether_del()). This achieves the following: 1. It brings up closer to having the network stack as a loadable module. 2. It allows the UUID generator to filter MAC addresses for best results (= highest chance of uniqeness). 3. MAC addresses can come from anywhere, irrespactive of whether it's used for an interface or not. A side-effect of the change is that when no MAC addresses have been added, a random multicast MAC address is created once and re-used if needed. Previusly, when a random MAC address was needed, it was created for every call. Thus, a change in behaviour is introduced for when no MAC addresses exist. Obtained from: Juniper Networks, Inc. |
