From 0bad834ca7bf9999ed9841f2bf9f5f07fbe02136 Mon Sep 17 00:00:00 2001 From: Taehee Yoo Date: Fri, 21 Aug 2020 17:47:32 +0000 Subject: ipvlan: advertise link netns via netlink Assign rtnl_link_ops->get_link_net() callback so that IFLA_LINK_NETNSID is added to rtnetlink messages. Test commands: ip netns add nst ip link add dummy0 type dummy ip link add ipvlan0 link dummy0 type ipvlan ip link set ipvlan0 netns nst ip netns exec nst ip link show ipvlan0 Result: ---Before--- 6: ipvlan0@if5: ... link/ether 82:3a:78:ab:60:50 brd ff:ff:ff:ff:ff:ff ---After--- 12: ipvlan0@if11: ... link/ether 42:b1:ad:57:4e:27 brd ff:ff:ff:ff:ff:ff link-netnsid 0 ~~~~~~~~~~~~~~ Signed-off-by: Taehee Yoo Signed-off-by: David S.
