As was reported [1], the iproute2 fails to compile on old systems,
in Cong's case, it was Fedora 19, in our case it was RedHat 7.2, which
failed with the following errors during compilation:
ipxfrm.c: In function ‘xfrm_selector_print’:
ipxfrm.c:479:7: error: ‘IPPROTO_MH’ undeclared (first use in this
function)
case IPPROTO_MH:
^
ipxfrm.c:479:7: note: each undeclared identifier is reported only once
for each function it appears in
ipxfrm.c: In function ‘xfrm_selector_upspec_parse’:
ipxfrm.c:1345:8: error: ‘IPPROTO_MH’ undeclared (first use in this
function)
case IPPROTO_MH:
^ make[1]: *** [ipxfrm.o] Error 1
The reason to it is the order of headers files. The IPPROTO_MH field is
set in kernel's UAPI header file (in6.h), but only in case
__UAPI_DEF_IPPROTO_V6 is set before. That define comes from other kernel's
header file (libc-compat.h) and is set in case there are no previous
libc relevant declarations.
In ip code, the include of <netdb.h> causes to indirect inclusion of
<netinet/in.h> and it sets __UAPI_DEF_IPPROTO_V6 to be zero and prevents from
IPPROTO_MH declaration.
This patch takes the simplest possible approach to fix the compilation
error by checking if IPPROTO_MH was defined before and in case it
wasn't, it defines it to be the same as in the kernel.

How to compile this.
--------------------
1. libdbm
arpd needs to have the db4 development libraries. For Debian
users this is the package with a name like libdb4.x-dev.
DBM_INCLUDE points to the directory with db_185.h which
is the include file used by arpd to get to the old format Berkeley
database routines. Often this is in the db-devel package.
2. make
The makefile will automatically build a config.mk file which
contains definitions of libraries that may or may not be available
on the system such as: ATM, ELF, MNL, and SELINUX.
3. To make documentation, cd to doc/ directory , then
look at start of Makefile and set correct values for
PAGESIZE=a4 , ie: a4 , letter ... (string)
PAGESPERPAGE=2 , ie: 1 , 2 ... (numeric)
and make there. It assumes, that latex, dvips and psnup
are in your path.
4. This package includes matching sanitized kernel headers because
the build environment may not have up to date versions. See Makefile
if you have special requirements and need to point at different
kernel include files.
