2023-09-09T4502: firewall: Add software flow offload using flowtableYuxiang Zhu
The following commands will enable nftables flowtable offload on interfaces eth0 eth1: ``` set firewall global-options flow-offload software interface <name> set firewall global-options flow-offload hardware interface <name> ``` Generated nftables rules: ``` table inet vyos_offload { flowtable VYOS_FLOWTABLE_software { hook ingress priority filter - 1; devices = { eth0, eth1, eth2, eth3 }; counter } chain VYOS_OFFLOAD_software { type filter hook forward priority filter - 1; policy accept; ct state { established, related } meta l4proto { tcp, udp } flow add @VYOS_FLOWTABLE_software } } ``` Use this option to count packets and bytes for each offloaded flow: ``` set system conntrack flow-accounting ``` To verify a connection is offloaded, run ``` cat /proc/net/nf_conntrack|grep OFFLOAD ``` This PR follows firewalld's implementation: https://github.com/firewalld/firewalld/blob/e748b97787d685d0ca93f58e8d4292e87d3f0da6/src/firewall/core/nftables.py#L590 A good introduction to nftables flowtable: https://thermalcircle.de/doku.php?id=blog:linux:flowtables_1_a_netfilter_nftables_fastpath
