vyos-netlinkd: T8047: replace netplugd

2026-03-19T21:37:45+00:00

Implementing a daemon that listens for netlink messages in Python was discussed for many years. This is a proof-of-concept implementation how we can listen for netlink messages and process them in Python. Python 3.10 minimum is required due to the use of case statements which mimics C-style switch/case instructions. Add example: set interfaces ethernet eth1 vif 21 address dhcp set interfaces ethernet eth1 vif 21 address dhcpv6 commit If network cable is unplugged: vyos-netlinkd[12681]: RTM_NEWLINK -> eth3.10, state=DOWN, mac=00:50:56:b3:9d:8e vyos-netlinkd[12681]: Stopping dhclient@eth3.10.service... vyos-netlinkd[12681]: Stopping dhcp6c@eth3.10.service... If cable is plugged back in: vyos-netlinkd[12681]: RTM_NEWLINK -> eth3.10, state=DOWN, mac=00:50:56:b3:9d:8e vyos-netlinkd[12681]: RTM_NEWLINK -> eth3.10, state=UP, mac=00:50:56:b3:9d:8e vyos-netlinkd[12681]: Restarting dhclient@eth3.10.service... vyos-netlinkd[12681]: Restarting dhcp6c@eth3.10.service...

T7591: remove copyright years from source files

2025-06-28T21:16:52+00:00

The legal team says years are not necessary so we can go ahead with it, since it will simplify backporting. Automatically removed using: git ls-files | grep -v libvyosconfig | xargs sed -i -E \ 's/^# Copyright (19|20)[0-9]{2}(-[0-9]{4})? VyOS maintainers.*/# Copyright VyOS maintainers and contributors /g' In addition we will error-out during "make" if someone re-adds a legacy copyright notice

netplug: T7360: DHCPv6 address is not cleared when interface goes oper-down

2025-04-14T19:26:47+00:00

When an interface goes down - e.g. cable unplugged - the DHCPv6 assigned IPv6 address is not removed from said interface. We should provide the same behavior as with IPv4. IPv6 address should be removed and dhcpv6 client restarted once the interface goes operational up again.

netplug: T7353: bugfix DHCP client not stopped when interface goes down

2025-04-14T18:24:56+00:00

The initial rewrite of vyos-netplug-dhcp-client by me tried to outsmart the DHCP client implementation by re-using vyos.ifconfig.Interface(). This added a regression where an interface loosing it's carrier no longer deconfigured it's IP address. This was a change in behavior form VyOS 1.3. In addition a bug is fixed as when a VLANs interface parent looses it's carrier we now also stop the DHCP client process. This script is now back to simply starting/stopping the DHCP client process.

netplug: T7346: only call interface helpers if interface is not removed

2025-04-10T15:09:04+00:00

When an interface is removed from the system also netplug is triggered. It makes no sense to call vyos.ifconfig.Interface() and update it's configuration when the interface was just recently removed. This would in fact re-add an interface temporarily in it's worst case.

netplug: T5103: only execute helper scripts on physical interfaces

2025-02-08T12:46:05+00:00

Helper scripts should only work on physical interfaces not on individual sub-interfaces. Moving e.g. a VLAN interface in/out a VRF will also trigger this script which should be prohibited - bail out early

netplug: T5491: invoke DHCP helpers also on wifi interfaces
