* netfilter: nft_tunnel: Add dst_cache supportwenxu2019-03-011-0/+7
| | | | | | | | | The metadata_dst does not initialize the dst_cache field, this causes problems to ip_md_tunnel_xmit() since it cannot use this cache, hence, Triggering a route lookup for every packet. Signed-off-by: wenxu <wenxu@ucloud.cn> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
* netfilter: nft_tunnel: Add NFTA_TUNNEL_MODE optionswenxu2019-02-041-2/+32

* netfilter: nf_tables: match on tunnel metadataPablo Neira Ayuso2018-08-031-1/+111
| | | | | | | | This patch allows us to match on the tunnel metadata that is available of the packet. We can use this to validate if the packet comes from/goes to tunnel and the corresponding tunnel ID. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>

This patch implements the tunnel object type that can be used to configure tunnels via metadata template through the existing lightweight API from the ingress path. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
