From bcad57182425426dd4aa14deb27f97acb329f3cd Mon Sep 17 00:00:00 2001 From: Daniel Borkmann Date: Fri, 3 Apr 2015 20:52:24 +0200 Subject: ebpf: add skb->priority to offset map for usage in {cls, act}_bpf This adds the ability to read out the skb->priority from an eBPF program, so that it can be taken into account from a tc filter or action for the use-case where the priority is not being used to directly override the filter classification in a qdisc, but to tag traffic otherwise for the classifier; the priority can be assigned from various places incl. user space, in future we may also mangle it from an eBPF program.
