For vlan dev, I think it's more complex. 1.Move vlan dev to a new ns, its real dev is in old ns, vlan can not work. 2.Move vlan real dev to a new ns, vlan dev is in old ns, vlan can not work. If someone want to move vlan and its real dev to new ns, he must do 1) and 2) or 2) and 1), both way are breaking the vlan down. I think move real dev to new ns, and add a new vlan dev will be better. Maybe I need write another patch for 'vlan'. >> >> Signed-off-by: Weilong Chen <chenweilong@huawei.com> >> --- >> drivers/net/bonding/bond_main.c | 3 +++ >> 1 file changed, 3 insertions(+) >> >> diff --git a/drivers/net/bonding/bond_main.c b/drivers/net/bonding/bond_main.c >> index f00dd45..897d153 100644 >> --- a/drivers/net/bonding/bond_main.c >> +++ b/drivers/net/bonding/bond_main.c >> @@ -3916,6 +3916,9 @@ void bond_setup(struct net_device *bond_dev) >> * capable >> */ >> >> + /* Don't allow bond devices to change network namespaces. */ >> + bond_dev->features |= NETIF_F_NETNS_LOCAL; >> + >> bond_dev->hw_features = BOND_VLAN_FEATURES | >> NETIF_F_HW_VLAN_CTAG_TX | >> NETIF_F_HW_VLAN_CTAG_RX | >> -- >> 1.7.12 >> >> >> -- >> To unsubscribe from this list: send the line "unsubscribe netdev" in >> the body of a message to majordomo@vger.kernel.org >> More majordomo info at http://vger.kernel.org/majordomo-info.html > > -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
