From bbfe367648be30a315db2fd69e197e1d63393327 Mon Sep 17 00:00:00 2001 From: Christian Poessinger Date: Sun, 28 Feb 2021 18:14:18 +0100 Subject: vif: T3349: use fixed ordering when enabling parent and child interface When a VIF/VLAN interface is placed in admin down state but the lower interface, serving the vlan, is moved from admin down -> admin up, all its vlan interfaces will be placed in admin up state, too. This is bad as a VLAN interface will become admin up even if its specified as admin down after a reboot. To reproduce: set interfaces ethernet eth1 vif 20 disable set interfaces ethernet eth1 disable commit delete interfaces ethernet eth1 disable commit Now check the interface state and it returns UP,LOWER_UP 7: eth1.20@eth1: mtu 1500 qdisc noqueue state UP group default qlen 1000 link/ether 00:50:56:b3:09:07 brd ff:ff:ff:ff:ff:ff inet6 fe80::250:56ff:feb3:907/64 scope link valid_lft forever preferred_lft forever (cherry picked from commit 49bc3f1e3ff8416908fc986bb60b444a75a1722d) --- python/vyos/ifconfig/bond.py | 14 ++------------ 1 file changed, 2 insertions(+), 12 deletions(-) (limited to 'python/vyos/ifconfig/bond.py') diff --git a/python/vyos/ifconfig/bond.py b/python/vyos/ifconfig/bond.py index 709222b09..199c69dde 100644 --- a/python/vyos/ifconfig/bond.py +++ b/python/vyos/ifconfig/bond.py @@ -343,9 +343,6 @@ class BondIf(Interface): if 'shutdown_required' in config: self.set_admin_state('down') - # call base class first - super().update(config) - # ARP monitor targets need to be synchronized between sysfs and CLI. # Unfortunately an address can't be send twice to sysfs as this will # result in the following exception: OSError: [Errno 22] Invalid argument. @@ -404,12 +401,5 @@ class BondIf(Interface): value = config.get('primary') if value: self.set_primary(value) - # Enable/Disable of an interface must always be done at the end of the - # derived class to make use of the ref-counting set_admin_state() - # function.
