Hi! The Netfilter project proudly presents: nftables 1.0.5 This release contains bugfixes (highlights): - Fixes for the -o/--optimize, run this --optimize option to automagically compact your ruleset using sets, maps and concatenations, eg. # cat ruleset.nft table ip x { chain y { type nat hook postrouting priority srcnat; policy drop; ip saddr 1.1.1.1 tcp dport 8000 snat to 4.4.4.4:80 ip saddr 2.2.2.2 tcp dport 8001 snat to 5.5.5.5:90 } } # nft -o -c -f ruleset.nft Merging: ruleset.nft:4:3-52: ip saddr 1.1.1.1 tcp dport 8000 snat to 4.4.4.4:80 ruleset.nft:5:3-52: ip saddr 2.2.2.2 tcp dport 8001 snat to 5.5.5.5:90 into: snat to ip saddr . tcp dport map { 1.1.1.1 . 8000 : 4.4.4.4 . 80, 2.2.2.2 . 8001 : 5.5.5.5 . 90 } - Fix ethernet and vlan concatenations, eg. define a dynamic set which is populated from the packet path. add table netdev x add chain netdev x y { type filter hook ingress device enp0s25 priority 0; } add set netdev x macset { typeof ether daddr . vlan id; flags dynamic,timeout; } add rule netdev x y update @macset { ether daddr . vlan id timeout 60s } or simply match using a concatenation: add rule netdev x y ether saddr . vlan id { 0a:0b:0c:0d:0e:0f . 42, 0a:0b:0c:0d:0e:0f . 4095 } counter accept - Fix ruleset listing with interface wildcard map, eg. table inet filter { chain INPUT { iifname vmap { "eth0" : jump input_lan, "wg*" : jump input_vpn } } chain input_lan {} chain input_vpn {} } - Fix several regressions in the input lexer which broke valid rulesets. - Fix slowdown with large lists of singleton interval elements. - Fix set automerge feature for large lists of singleton interval elements. - Fix bogus error reporting for exact overlaps. - Fix segfault when adding elements to invalid set. - fix device parsing in netdev family in json.
