Doc Text:	This update ensures that VLAN interfaces are restarted when underlying devices are restarted after a device configuration change, allowing the successful restoration of networks. Prior to this update, a VLAN interface was not restarted when the underlying device was restarted. Network routes using the VLAN interface as the next hop were removed and not restored. With this update, the VLAN interfaces are restarted when the underlying devices are restarted. Network routes are restored.

Description Cyril Lopez 2018-11-30 09:32:49 UTC

Description of problem:

When a change is needed on bond, os-net-config write the configuration and restart nic and bond. But it will not restart vlan on top of the bond. So all route from vlan are lost. The solution should be on restart of a bond, restart after all related vlan.

Version-Release number of selected component (if applicable):
os-net-config-5.2.3-2.el7ost.noarch

Steps to Reproduce:
1. deploy a network topology with nic in a bond and vlan the bond with static route.
2. change a param on bond in /etc/os-net-config/config.json
3. os-net-config -c /etc/os-net-config/config.json
4. check the route are lost.

Example with vlan1421 on bond0 :

Do a change and call os-net-config

Here our route on vlan1421 are lost because when bond0 is down, all routes of vlan based on bond0 are lost. VLANs are M-DOWN.

Comment 2 Harald Jensås 2018-11-30 10:12:19 UTC

I wrote a unit test for this, and it confirms vlan is not restarted.


os_net_config/tests/test_impl_ifcfg.py

    def test_restart_vlans_on_bond_change(self):
        self.ifup_interface_names = []
        interface1 = objects.Interface('em1')
        interface2 = objects.Interface('em2')
        bond = objects.LinuxBond('bond0', members=[interface1, interface2])
        vlan = objects.Vlan('bond0', 10)
        self.provider.add_interface(interface1)
        self.provider.add_interface(interface2)
        self.provider.add_linux_bond(bond)
        self.provider.add_vlan(vlan)
        self.provider.apply()
        self.assertIn('bond0', self.ifup_interface_names)
        self.assertIn('em1', self.ifup_interface_names)
        self.assertIn('em2', self.ifup_interface_names)
        self.assertIn('vlan10', self.ifup_interface_names)

        # Change the bond configuration
        self.ifup_interface_names = []
        bond = objects.LinuxBond('bond0', members=[interface1, interface2],
                                 bonding_options='mode=1 miimon=100')
