Date: Wed, 23 Sep 2015 14:43:46 +0300 From: Andrey Vagin <avagin@...nvz.org> To: netdev@...r.kernel.org Cc: Stephen Hemminger <shemminger@...l.org>, Andrew Vagin <avagin@...nvz.org> Subject: [PATCH iproute2] route: filter routes by family if it's specified From: Andrew Vagin <avagin@...nvz.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.
