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

2022-11-03validators: T4795: migrate mac-address python validator to validate-valueChristian Poessinger
Instead of spawning the Python interpreter for every mac-address to validate, rather use the base validate-value OCaml implementation which is much faster. This removes redundant code and also makes the CLI more responsive. Validator is moved out to a dedicated file instead of using XML inlined <regex> for the reason of re-usability. So if that regex needs to be touched again - it can all happen in one single file.

Add support for arbitrary netmasks on source/destination addresses in firewall rules. This is particularly useful with DHCPv6-PD when the delegated prefix changes periodically.

2022-09-22xml: T4698: validating a range must be explicitly enabled in the validatorChristian Poessinger
This extends commit 28573ffe4f ("xml: T4698: drop validator name="range" and replace it with numeric"). The first version allowed both a range and discrete numbers to be validated by the numeric validator. This had a flaw as both 22 and 22-30 were valid at the same time. The generic "port-number.xml.i" building block only allows a discrete number. Now if a user set port 22-30 for e.g. SSH the daemon did no longer start. This is why range validation must be explicitly enabled.

2022-09-16xml: T4698: drop validator name="range" and replace it with numericChristian Poessinger
After T4669 added support for range validation to the OCaml validator there is no need to keep the slow Python validator in place. Raplace all occurances of <validator name="range" argument="--min=1 --max=65535"/> with <validator name="numeric" argument="--range 1-65535"/>.
