* nft-ruleparse: Introduce nft_create_target()Phil Sutter2023-08-101-3/+2
| | | | | | | | | | | | | | | | Like nft_create_match(), this is a small wrapper around the typical target extension lookup and (standard) init code. To use it from nft_parse_target() and nft_parse_log(), introduce an inner variant which accepts the target payload size as parameter. The call to rule_parse_ops::target callback was problematic with standard target, because the callbacks initialized iptables_command_state::jumpto with the target name, "standard" in that case. Perform its tasks in nft_create_target(), keep it only for bridge family's special handling of watcher "targets". Signed-off-by: Phil Sutter <phil@nwl.cc>
* nft: ruleparse: Create family-specific source filesPhil Sutter2023-05-031-0/+5
| | | | | | | Extract the remaining nftnl rule parsing code from nft-<family>.c sources into dedicated ones to complete the separation. Signed-off-by: Phil Sutter <phil@nwl.cc>
* nft: Extract rule parsing callbacks from nft_family_opsPhil Sutter2023-05-031-0/+16
| | | | | | | Introduce struct nft_ruleparse_ops holding the family-specific expression parsers and integrate it into nft_family_ops for now. Signed-off-by: Phil Sutter <phil@nwl.cc>
* nft: Introduce nft-ruleparse.{c,h}Phil Sutter2023-05-031-0/+117
Extract all code dealing with parsing from struct nftnl_rule into struct iptables_command_state from nft-shared.c into a separate source file. Basically this is nft_rule_to_iptables_command_state() and the functions it calls, plus family-independent parsers called from family-specific callbacks. Signed-off-by: Phil Sutter <phil@nwl.cc>
