firewall: T970: Add firewall group domain-group
Domain group allows to filter addresses by domain main Resolved addresses as elements are stored to named "nft set" that used in the nftables rules Also added a dynamic "resolver" systemd daemon vyos-domain-group-resolve.service which starts python script for the domain-group addresses resolving by timeout 300 sec set firewall group domain-group DOMAINS address 'example.com' set firewall group domain-group DOMAINS address 'example.org' set firewall name FOO rule 10 action 'drop' set firewall name FOO rule 10 source group domain-group 'DOMAINS' set interfaces ethernet eth0 firewall local name 'FOO' nft list table ip filter table ip filter { set DOMAINS { type ipv4_addr flags interval elements = { 192.0.2.1, 192.0.2.85, 203.0.113.55, 203.0.113.58 } } chain NAME_FOO { ip saddr @DOMAINS counter packets 0 bytes 0 drop comment "FOO-10" counter packets 0 bytes 0 return comment "FOO default-action accept" } }
