datapath/garp: Rework and improvement of garp package #38198

dylandreimerink · 2025-03-14T11:15:54Z

This work started out as an effort to support multiple devices for pod announcements. I also ended up doing a lot of cleanup and refactoring of the garp package.

The gARP sender has written such that a single device was set during construction and could not be changed. I removed all state from the sender, instead requiring that you first obtain an Interface from it then use it to send the gARP packets. This allows the user to reuse the Interface when possible, and to send on a changing set of devices.

The processor got an additional flag to match multiple devices. The old flag is deprecated. The constructor turns the old value into a regex that matches a device name exactly. The processor received a bit of cleanup, removing logs, and switching to slog.

The processor is now in charge of managing which interfaces to send gARP packets on. It has a one shot job that subscribes to selected devices from the device table, and filters them based on the regex given by the user. When called by the endpoint manager, it will send gARP packets on all selected devices matching the users filter.

Lastly, I reworded the tests. They are now faster, no longer time based, and cover the new functionality.

Fixes: #37545

Added multi-device support to the L2 pod announcement feature

I just looked at the doc changes: it looks fine (one non-blocking suggestion below). Thanks!

datapath package looks good to me. Some nits.
