+ libnetfilter_conntrack is a userspace library providing a programming
+ interface (API) to the in-kernel connection tracking state table. The
+ library libnetfilter_conntrack has been previously known as
+ libnfnetlink_conntrack and libctnetlink. This library is currently
+ used by conntrack-tools among many other applications.

+Subject: conntrack: fix build with kernel 5.15 and musl
+
+Currently, with kernel 5.15 headers and musl building is failing with
+redefinition errors due to a conflict between the kernel and musl headers.
+
+Musl is able to suppres the conflicting kernel header definitions if they
+are included after the standard libc ones, however since ICMP definitions
+were moved into a separate internal header to avoid duplication this has
+stopped working and is breaking the builds.
+
+It seems that the issue is that <netinet/in.h> which contains the UAPI
+suppression defines is included in the internal.h header and not in the
+proto.h which actually includes the kernel ICMP headers and thus UAPI
+supression defines are not present.
+
+Solve this by moving the <netinet/in.h> include before the ICMP kernel
+includes in the proto.h
+
+Fixes: bc1cb4b11403 ("conntrack: Move icmp request>reply type mapping to common file")
