Patch from Lars Kellogg-Stedman:
I'm building BusyBox using a development kit for MontaVista Hardhat Linux
(PPC) -- which, at least in this instance, is based around kernel 2.2.14.
I've had to massage a few files in networking/libiproute/ to make it
compile. Specifically:
(1) Added a #include <sys/uio.h> for the iovec structure in
libnetlink.c,
(2) Put ifdefs in ll_types.c and ll_proto.c around various
constants (ETH_P_xxx and ARPHRD_xxx) that weren't defined,
(3) Make do_changename() in iplink.c require a kernel >=
2.4.0 -- the ifr structure in my environment doesn't
have the ifr_name attribute. I've assumed this is
a kernel dependency -- let me know if I ought to be
checking something else.
In the absence of the correct kernel, do_changename()
always returns 0.
Attached is a patch against the current CVS that will make these changes.
