Series applied, thanks. Although I agree with the sentiment that this thing can cause surprising results and can be asking for trouble. If someone wants to filter traffic "by UID" they might make a simple ingress TC ebpf program using these new interfaces and expect it to work. But the UID their program will see will be the UID of whatever randomly happened to be executing when the packet was received and processed. So for these kinds of things such identifying markers are less useful, and perhaps surprising in their results. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
