Message-ID: <1393573839-32316-2-git-send-email-dingtianhong@huawei.com> Date: Fri, 28 Feb 2014 15:50:38 +0800 From: Ding Tianhong <dingtianhong@...wei.com> To: <kaber@...sh.net>, <julia.lawall@...6.fr> CC: <joe@...ches.com>, <davem@...emloft.net>, <netdev@...r.kernel.org> Subject: [PATCH net-next 1/2] vlan: don't allow vlan device to move between network namespaces Now the vlan device could move to another network namespace, but the read dev is sill in the old network namespace, it is unsafe and the vlan device could not work well, so don't allow to do it.
