Venkat Venkatsubra 2297839708 ipvlan: handle NETDEV_DOWN event ... In case of stacked devices, to help propagate the down link state from the parent/root device (to this leaf device), handle NETDEV_DOWN event like it is done now for NETDEV_UP. In the below example, ens5 is the host interface which is the parent of the ipvlan interface eth0 in the container. Host: [root@gkn-podman-x64 ~]# ip link set ens5 down [root@gkn-podman-x64 ~]# ip -d link show dev ens5 3: ens5: <BROADCAST,MULTICAST> mtu 9000 qdisc mq state DOWN ... [root@gkn-podman-x64 ~]# Container: [root@testnode-ol8 /]# ip -d link show dev eth0 2: eth0@if3: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 9000 state UNKNOWN ... ipvlan mode l2 bridge ... [root@testnode-ol8 /]# eth0's state continues to show up as UP even though ens5 is now DOWN. For macvlan the handling of NETDEV_DOWN event was added in commit 80fd2d6ca5 ("macvlan: Change status when lower device goes down").
