From: Andrew Vagin <ava...@openvz.org>
Currently when we specify AF_INET6 when it is disabled, we will get
all routes.
For example, we can boot kernel with ipv6.disable=1 and try to get ipv6
routes:
$ ip -6 route show
default via 192.168.122.1 dev eth0 proto static metric 100
192.168.122.0/24 dev eth0 proto kernel scope link src 192.168.122.141
metric 100
Here are ipv4 routes and this is unexpected behaviour.
