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.
See changelog for more details (attached to this email).
