As we can see from vxlan_build/parse_gbp_hdr(), when processing metadata on vxlan rx/tx path, only dont_learn/policy_applied/policy_id fields can be set to or parse from the packet for vxlan gbp option. So do the mask when set it in lwtunnel, as it does in act_tunnel_key and cls_flower. Signed-off-by: Xin Long <lucien.xin@gmail.com> --- net/ipv4/ip_tunnel_core.c | 1 + 1 file changed, 1 insertion(+)
