The reason why they both have it is that the linux/* definition are the
kernel ones, the netinet/in.h ones are what glibc copied from the kernel
ones. Userspace programs should *never* include linux/* headers. If you need
an interface not in glibc, you should bug them to make appropriate copies.
That's what I expected.
So I've successfully updated traceroute6 to use all the right bits from
glibc and not touch /usr/include/linux/ at all. tracepath and
tracepath6 are a bit harder, though, since they make use of Linux error
queues as defined in /usr/include/linux/errqueue.h. I can't seem to
find any interface between the glibc headers and the kernel. Does one
exist, or will these programs continue to require linux/errqueue.h?
Well, if there is no alternative, I guess you can't avoid it. It also makes
the code linux specific. But when it comes to networking stuff which works
cross platform/architechture, use the interfaces provided.
Maybe the fix is as simple as deleting any lines saying #include <linux/*>
and remove all those editted header files too.
It was almost that easy, but some types needed to be updated since the
code was using things like __u32, which is defined in linux/types.h.
If it works across all the required platforms, you've suceeded. Ofcourse,
when BSD and Hurd get added to Debian, you can do it again :)
