The goal of this series is to ease the user to follow an interface that moves to another netns. After this series, with a patched iproute2: $ ip netns bar foo $ ip monitor link & $ ip link set dummy0 netns foo Deleted 5: dummy0: <BROADCAST,NOARP> mtu 1500 qdisc noop state DOWN group default link/ether 6e:a7:82:35:96:46 brd ff:ff:ff:ff:ff:ff new-nsid 0 new-ifindex 6 => new nsid: 0, new ifindex: 6 (was 5 in the previous netns) $ ip link set eth1 netns bar Deleted 3: eth1: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN group default link/ether 52:54:01:12:34:57 brd ff:ff:ff:ff:ff:ff new-nsid 1 new-ifindex 3 => new nsid: 1, new ifindex: 3 (same ifindex) $ ip netns bar (id: 1) foo (id: 0) include/linux/rtnetlink.h | 5 +++-- include/uapi/linux/if_link.h | 1 + net/core/dev.c | 22 ++++++++++++---------- net/core/rtnetlink.c | 31 ++++++++++++++++++++----------- 4 files changed, 36 insertions(+), 23 deletions(-) Comments are welcomed, Regards, Nicolas
