netfilter: nft_flow_offload: fix interaction with vrf slave device
In the forward chain, the iif is changed from slave device to master vrf device. Thus, flow offload does not find a match on the lower slave device. This patch uses the cached route, ie. dst->dev, to update the iif and oif fields in the flow entry. After this patch, the following example works fine: # ip addr add dev eth0 1.1.1.1/24 # ip addr add dev eth1 10.0.0.1/24 # ip link add user1 type vrf table 1 # ip l set user1 up # ip l set dev eth0 master user1 # ip l set dev eth1 master user1 # nft add table firewall # nft add flowtable f fb1 { hook ingress priority 0 \; devices = { eth0, eth1 } \; } # nft add chain f ftb-all {type filter hook forward priority 0 \; policy accept \; } # nft add rule f ftb-all ct zone 1 ip protocol tcp flow offload @fb1 # nft add rule f ftb-all ct zone 1 ip protocol udp flow offload @fb1 Signed-off-by: wenxu <wenxu@ucloud.cn> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
