+Date: Mon, 16 May 2022 18:16:41 +0200
+Subject: treewide: use uint* instead of u_int*
+
+Gcc complains about missing types. Some commits introduced u_int* instead
+of uint*. Use uint treewide.
+
+Fixes errors in the form of:
+In file included from xtables-legacy-multi.c:5:
+xshared.h:83:56: error: unknown type name 'u_int16_t'; did you mean 'uint16_t'?
+    83 | set_option(unsigned int *options, unsigned int option, u_int16_t *invflg,

+make[6]: *** [Makefile:712: xtables_legacy_multi-xtables-legacy-multi.o] Error 1
+
+Avoid libipq API breakage by adjusting libipq.h include accordingly. For
+arpt_mangle.h kernel uAPI header, apply same change as in kernel commit
+e91ded8db5747 ("uapi: netfilter_arp: use __u8 instead of u_int8_t").

+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+This reverts commit c5d9a723b5159a28f547b577711787295a14fd84 as it broke
+compiling against musl libc. Might be a bug in the latter, but for the
+time being try to please both by avoiding the include and instead
+defining ETH_ALEN if unset.
+
+While being at it, move netinet/ether.h include up.

+Subject: libxtables: Unexport init_extensions*() declarations
+
+The functions are used for static builds to initialize extensions after
+libxtables init. Regular library users should not need them, but the
+empty declarations introduced in #else case (and therefore present in
+user's env) may clash with existing symbol names.
+
+Avoid problems and guard the whole block declaring the function
+prototypes and mangling extensions' _init functions by XTABLES_INTERNAL.
