The following error causes this test to fail in iptables_network_unlock_internal() during restore:

2023-12-28T07:09:22.4387062Z b'(00.011015) net: Unlock network'

iptables_restore() is using iptables-restore instead of iptables-legacy-restore.

@avagin This error appears with Alpine v3.19 because iptables-nft is now the default iptables backend.
I've opened the following pull request with a fix: #2323

In addition to the error above, nft_run_cmd_from_buffer(nft, buf) fails during restore when running zdtm/static/socket-tcp-nfconntrack with nftables v1.0.9:

For this input, the nft tool shows the following error:

                                             ^^^^^^^^^^^^^^^^^^^^

This test works with nftables v1.0.7, where the value of buf is the following

table ip filter {
        chain INPUT {
                type filter hook input priority filter; policy accept;
                counter packets 0 bytes 0 jump CRIU
-                iifname "lo" ip protocol tcp xt match "conntrack" counter packets 3 bytes 172 accept
+                iifname "lo" meta l4proto tcp ct state new,established counter packets 3 bytes 172 accept
                counter packets 0 bytes 0 drop
        }

        chain CRIU {
                meta mark 0x0000c114 counter packets 0 bytes 0 accept   
                counter packets 0 bytes 0 drop
        }

        chain OUTPUT { 
                type filter hook output priority filter; policy accept;
                counter packets 0 bytes 0 jump CRIU
        }
}

The following steps can be used to replicate the problem in Alpine container:

$ nft --version
nftables v1.0.9 (Old Doc Yak #3)
$ iptables-nft --version
iptables v1.8.10 (nf_tables)

$ iptables-translate -A INPUT -i lo -p tcp -m state --state NEW,ESTABLISHED -j ACCEPT
nft 'add rule ip filter INPUT iifname "lo" ip protocol tcp ct state new,established counter accept'

table ip filter {
	chain INPUT {
		type filter hook input priority filter; policy accept;
		iifname "lo" ip protocol tcp xt match "conntrack" counter packets 0 bytes 0 accept
	}
}

$ nft flush ruleset
