After nft v0.8.1 "flow table" is renamed as meter.
This should reflect in iptables to nftables translation.
Before this patch:
$ iptables-translate -A INPUT -m tcp -p tcp --dport 80 -m hashlimit
--hashlimit-above 200/sec --hashlimit-mode srcip,dstport
--hashlimit-name http1 -j DROP
nft add rule ip filter INPUT tcp dport 80 flow table http1 { tcp dport .
ip saddr limit rate over 200/second } counter drop
After this patch:
$ iptables-translate -A INPUT -m tcp -p tcp --dport 80 -m hashlimit
--hashlimit-upto 200 --hashlimit-mode srcip --hashlimit-name http3
--hashlimit-srcmask 24 -j DROP
nft add rule ip filter INPUT tcp dport 80 meter http3 { ip saddr and
255.255.255.0 limit rate 200/second } counter drop

This patch adds test cases for iptables to nft translation of cluster match
This adds all test cases including corner cases.
Run these test cases like:
$ ./xlate-test.py extensions/libxt_cluster.txlate

Add translation for cluster to nft
$ sudo iptables-translate -A PREROUTING -t mangle -i eth1 -m cluster
--cluster-total-nodes 7 --cluster-local-node 5 --cluster-hash-seed
0xdeadbeef -j MARK --set-mark 0xffff
nft add rule ip mangle PREROUTING iifname eth1 jhash ct original saddr
mod 7 seed 0xdeadbeef eq 5 meta pkttype set host counter meta mark set
0xffff
$ sudo iptables-translate -A PREROUTING -t mangle -i eth1 -m cluster
--cluster-total-nodes 7 --cluster-local-nodemask 5 --cluster-hash-seed
0xdeadbeef -j MARK --set-mark 0xffff
nft add rule ip mangle PREROUTING iifname eth1 jhash ct original saddr
mod 7 seed 0xdeadbeef { 0, 2 } meta pkttype set host counter meta
mark set 0xffff

Fix wrong appending of jump verdict after the comment
For example:
$ iptables-translate -A INPUT -p tcp -m tcp --sport http -s 192.168.0.0/16 -d 192.168.0.0/16 -j LONGNACCEPT -m comment --comment "foobar"
nft add rule ip filter INPUT ip saddr 192.168.0.0/16 ip daddr 192.168.0.0/16 tcp sport 80 counter comment \"foobar\"jump LONGNACCEPT
Note that even without comment with double-quotes (i.e. --comment
"foobar"), it will add quotes:
$ iptables-translate -A FORWARD -p tcp -m tcp --sport http -s 192.168.0.0/16 -d 192.168.0.0/16 -j DROP -m comment --comment singlecomment
nft add rule ip filter FORWARD ip saddr 192.168.0.0/16 ip daddr 192.168.0.0/16 tcp sport 80 counter comment \"singlecomment\"drop
Attempting to apply the translated/generated rule will result to:
$ nft add rule ip filter INPUT ip saddr 192.168.0.0/16 ip daddr 192.168.0.0/16 tcp sport 80 counter comment \"foobar\"jump LONGNACCEPT
<cmdline>:1:111-114: Error: syntax error, unexpected jump, expecting endof file or newline or semicolon
add rule ip filter INPUT ip saddr 192.168.0.0/16 ip daddr 192.168.0.0/16 tcp sport 80 counter comment "foobar"jump LONGNACCEPT
After this patch
$ iptables-translate -A INPUT -p tcp -m tcp --sport http -s 192.168.0.0/16 -d 192.168.0.0/16 -j LONGNACCEPT -m comment --comment "foobar"
nft add rule ip filter INPUT ip saddr 192.168.0.0/16 ip daddr 192.168.0.0/16 tcp sport 80 counter jump LONGNACCEPT comment \"foobar\"
which is correct translation

Replace gethostbyaddr() with getnameinfo() as getnameinfo()
deprecates the former and allows programs to
eliminate IPv4-versus-IPv6 dependencies
