* Revert --compat option related commitsPhil Sutter2023-09-011-10/+5
| | | | | | | | | | | | | | | | | | | This reverts the following commits: b14c971db6db0 ("tests: Test compat mode") 11c464ed015b5 ("Add --compat option to *tables-nft and *-nft-restore commands") ca709b5784c98 ("nft: Introduce and use bool nft_handle::compat") 402b9b3c07c81 ("nft: Pass nft_handle to add_{target,action}()") This implementation of a compatibility mode implements rules using xtables extensions if possible and thus relies upon existence of those in kernel space. Assuming no viable replacement for the internal mechanics of this mode will be found in foreseeable future, it will effectively block attempts at deprecating and removing of these xtables extensions in favor of nftables expressions and thus hinder upstream's future plans for iptables.

* Add --compat option to *tables-nft and *-nft-restore commandsPhil Sutter2023-08-111-5/+10
| | | | | | | | | | | | | | | The flag sets nft_handle::compat boolean, indicating a compatible rule implementation is wanted. Users expecting their created rules to be fetched from kernel by an older version of *tables-nft may use this to avoid potential compatibility issues. Changes since v1: - Expect short option '-C' in {ip,ip6,eb}tables-nft-restore command line parser - Support -C/--compat in arptables-nft-restore, too - Update man pages with the new flag Signed-off-by: Phil Sutter <phil@nwl.cc>
