cni host-device causes ip leak after reboot node

[hangzhouwanjun]

host-device config such as：

config: '{
"cniVersion": "0.3.0",
"name": "net-test-single-ens11",
"device": "ens11",
"type": "host-device",
"ipam": {
"type": "host-local",
"ranges": [[{"subnet":"1.1.0.0/16","gateway":"1.1.0.1"},{"subnet":"2.2.0.0/16","gateway":"2.2.0.1"},{"subnet":"3.3.0.0/16","gateway":"3.3.0.1"}]]
}
}
host-device causes ip leak after reboot node

cmdDel code such as：

func cmdDel(args *skel.CmdArgs) error {
cfg, err := loadConf(args.StdinData)
if err != nil {
return err
}
if args.Netns == "" {
return nil
}
containerNs, err := ns.GetNS(args.Netns)
if err != nil {
return fmt.Errorf("failed to open netns %q: %v", args.Netns, err)
}
defer containerNs.Close()

if cfg.IPAM.Type != "" {
	if err := ipam.ExecDel(cfg.IPAM.Type, args.StdinData); err != nil {
		return err
	}
}

if !cfg.DPDKMode {
	if err := moveLinkOut(containerNs, args.IfName); err != nil {
		return err
	}
}

return nil

}
There no netns after reboot node，so ipam.ExecDel never exec，ip will leak
