iptables: rework ip(6)tables-nft dependencies
according to iptables-nft man page,
"These tools use the libxtables framework extensions and hook to the nf_tables
kernel subsystem using the nft_compat module."
This means that to work, iptables-nft needs the same modules as
iptables legacy except the ip(6)table-{filter,mangle,nat,raw}
ip_tables, ip6tables.
When those modules are loaded iptables-nft-save output contains
"# Warning: iptables-legacy tables present, use iptables-legacy-save to see them"
But as long as it's empty it should not be a problem.
To have nft properly display the rules created by ip(6)tables-nft we need
all iptables targets and matches to be built as extension and not built-in
(/usr/lib/iptables/libip(6)t_*.so)
When switching a package to iptables-nft, you need to keep the
iptables-mod-* dependencies
This patch does minimal changes:
- remove the direct iptables-nft -> iptables dependency
- and more important add nft-compat dependency
The rule
iptables-nft -A OUTPUT -d 8.8.8.8 -m comment --comment "aaa" -j REJECT
becomes
table ip filter {
chain OUTPUT {
type filter hook output priority filter; policy accept;
ip daddr 8.8.8.8 # xt_comment counter packets 0 bytes 0 # xt_REJECT
}
}
