Right, but what actually happens in this case? The sign extension bug means it will appear as if the flags in ifr_flagshigh are set (and perhaps those flags will be written back to the kernel, too). But I could see certain use cases being unaffected by the bug. To rephrase my original question perhaps: how did you discover the bug? It doesn't matter in terms of the correctness of your fix; I'm just curious about the fact that we didn't discover it for so long. -Ed _______________________________________________ dev mailing list dev@openvswitch.org http://openvswitch.org/mailman/listinfo/dev
