* include: include <std{bool,int}.h> via <nft.h>Thomas Haller2023-08-251-1/+0
| | | | | | | | | | | | | | | | | | | | There is a minimum base that all our sources will end up needing. This is what <nft.h> provides. Add <stdbool.h> and <stdint.h> there. It's unlikely that we want to implement anything, without having "bool" and "uint32_t" types available. Yes, this means the internal headers are not self-contained, with respect to what <nft.h> provides. This is the exception to the rule, and our internal headers should rely to have <nft.h> included for them. They should not include <nft.h> themselves, because <nft.h> needs always be included as first. So when an internal header would include <nft.h> it would be unnecessary, because the header is *always* included already.

* exthdr: add boolean DCCP option matchingJeremy Sowden2023-06-011-0/+42
Iptables supports the matching of DCCP packets based on the presence or absence of DCCP options. Extend exthdr expressions to add this functionality to nftables.
