wenxu a96a8cb050 net/sched: cls_flower: fix only mask bit check in the validate_ct_state ... [ Upstream commit afa536d840 ] The ct_state validate should not only check the mask bit and also check mask_bit & key_bit.. For the +new+est case example, The 'new' and 'est' bits should be set in both state_mask and state flags. Or the -new-est case also will be reject by kernel. When Openvswitch with two flows ct_state=+trk+new,action=commit,forward ct_state=+trk+est,action=forward A packet go through the kernel and the contrack state is invalid, The ct_state will be +trk-inv. Upcall to the ovs-vswitchd, the finally dp action will be drop with -new-est+trk.
