In cls_cgroup_classify(), if skb->sk is NULL, we can try to restore classid form skb->bk_classid. Libo Chen (4): net: introduce bk_classid to struct sk_buff cls_cgroup: introduce a helper: bk_cls_classid() veth: backup classid befor switch net_ns cls_cgroup: restore classid from skb->sk_classid drivers/net/veth.c | 5 +++++ include/linux/skbuff.h | 3 +++ include/net/cls_cgroup.h | 11 +++++++++++ net/sched/cls_cgroup.c | 8 ++++---- 4 files changed, 23 insertions(+), 4 deletions(-)
