It is a common access attempt due to library probing.  We commonly
dontaudit it, but you could allow the read-only form (i.e. create read
write nlmsg_read) to get routing information without being able to
modify it (which requires nlmsg_write).  Note the distinction:  read and
write permission means the ability to communicate with the kernel over
the socket which is required for any kind of operation, whereas
nlmsg_read and nlmsg_write correspond to the actual reading and writing
of the routing table info (or other netlink-provided data).
