Jakub Sitnicki ee53b42fd8 iproute: Abort if nexthop cannot be parsed
Attempt to add a multipath route where a nexthop definition refers to a
non-existent device causes 'ip' to crash and burn due to stack buffer
overflow:

  # ip -6 route add fd00::1/64 nexthop dev fake1
  Cannot find device "fake1"
  Cannot find device "fake1"
  Cannot find device "fake1"
  ...
  Segmentation fault (core dumped)

Don't ignore errors from the helper routine that parses the nexthop
definition, and abort immediately if parsing fails.

This is a set of utilities for Linux networking.

Stable version repository:

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.
