It would be very useful to retrieve the net_cls's classid from an eBPF program to allow for a more fine-grained classification, it could be directly used or in conjunction with additional policies. I.e. docker, but also tooling such as cgexec, can easily run applications via net_cls cgroups: cgcreate -g net_cls:/foo echo 42 > foo/net_cls.classid cgexec -g net_cls:foo <prog> Thus, their respecitve classid cookie of foo can then be looked up on the egress path to apply further policies. The helper is desigend such that a non-zero value returns the cgroup id.
