Hello, I've been trying to build many netfilter.org projects on a system with the musl libc library. Alas, I often get errors about undeclared u_int8_t, ... musl will declare these types when <sys/types.h> is included and _GNU_SOURCE or _BSD_SOURCE is set. However many netfilter.org projects don't include <sys/types.h>. On the other hand, changing the types to the <stdint.h> uint*_t works in most cases because <netinet/in.h> is often included, which (by POSIX) includes <inttypes.h> which includes <stdint.h>. (Sometimes <stdint.h> or <inttypes.h> is also directly included.) In some cases u_int*_t and uint*_t types are mixed, so I am going to prepare a patch series which changing them and making sure that the public headers explicitly include <stdint.h> if they use these types. Assuming these (relatively invasive in terms of changed lines of code) changes are acceptable, I have some questions: Are the linux_nfnetlink_*.h only used as includes from other headers? (so that they don't need an explicit #include <stdint.h>) Is there anything I need to be careful about? There are also kernel types (e.g. __u8) in some places. Should I also bother about these while I'm at it? These were not problematic for me since these (mostly?) kernel headers include <linux/types.h>.
