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.

T7182: use Config instead of ConfigTreeQuery for get_interface_dict

T7182: normalize formatting

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: T5476: rewrite dhclient helper from Perl -> Python

2023-08-16T11:22:14+00:00

There are two hooks called for bridge, ethernet and bond interfaces if the link-state changes up -> down or down -> up. The helpers are: * /etc/netplug/linkdown.d/dhclient * /etc/netplug/linkup.d/dhclient As those helpers use Linux actions to start/restart the dhclient process in Perl it's time to rewrite it. First goal is to get rid of all Perl code and the second is that we now have a Proper Python library. Instead of checking if the process is running the then restarting it without even systemd noticing (yeah we might get two processes beeing alive) we should: * Add a Python helper that can be used for both up and down (see man 8 netplugd FILES section) * Query the VyOS CLI config if the interface in question has DHCP(v6) configured and is not disabled * Add IPv6 DHCPv6 support MAN page: https://linux.die.net/man/8/netplugd
