Here is the problem:
[]# nft -v
nftables v0.9.8 (E.D.S.)
[]# iptables-nft -v
iptables v1.8.7 (nf_tables): no command specified
Try `iptables -h' or 'iptables --help' for more information.
[]# nft flush ruleset
[]# ip6tables-nft -t nat -A POSTROUTING -j MASQUERADE --random-full
[]# nft list ruleset
table ip6 nat {
chain POSTROUTING {
type nat hook postrouting priority srcnat; policy accept;
counter packets 0 bytes 0 masquerade random-fully
}
}
[]# nft list ruleset > /tmp/ruleset
[]# nft flush ruleset
[]# nft -f /tmp/ruleset
/tmp/ruleset:4:54-54: Error: syntax error, unexpected newline
counter packets 0 bytes 0 masquerade random-fully
That's because nft list ruleset saves "random-fully" which is wrong
format for nft -f, right should be "fully-random".
We face this problem because we run k8s in Virtuozzo container, and k8s
creates those "random-fully" rules by iptables(nft) and then CRIU can't
restore those rules using nft.

This structure is an extensible containers of parameters, so we don't
need to propagate interface updates in every extension file in case
we need to add new parameters in the future.

The multiport match needs it, this basically leaves ->xlate() indirection
with almost the same interface as ->print().

Add translation for masquerade to nftables.
Examples:
$ sudo ip6tables-translate -t nat -A POSTROUTING -j MASQUERADE
nft add rule ip6 nat POSTROUTING counter masquerade
$ sudo ip6tables-translate -t nat -A POSTROUTING -p tcp -j MASQUERADE --to-ports 10
nft add rule ip6 nat POSTROUTING ip6 nexthdr tcp counter masquerade to :10
$ sudo ip6tables-translate -t nat -A POSTROUTING -p tcp -j MASQUERADE --to-ports 10-20 --random
nft add rule ip6 nat POSTROUTING ip6 nexthdr tcp counter masquerade to :10-20 random
