VyOS 1.4.0-epa2

Hello, Community!

VyOS 1.4.0-epa2 image is now available to customers and contributors (and everyone can build it from the sagitta branch of vyos-build, of course)! If you are new to VyOS, the "EPA" part means "early production access" — the final stage when the release is already used in production by a subset of users and on our proper infrastructure. This is the second release on the path to the final stabilization of the 1.4.0/Sagitta branch. It mainly features bug fixes but contains minor features 

New features

If you didn't know, VyOS supports unicast VRRP mode — it comes in handy in weird networks where multicast doesn't work correctly and allows VRRP to function even if someone intentionally disabled all multicast traffic. Before, this functionality was limited to creating an HA pair. However, now you can configure multiple peers with more than one backup router.

set high-availability vrrp group MyGroup peer-address
set high-availability vrrp group MyGroup peer-address

Another noticeable improvement is a new operational mode command to remove all container images at once: delete container image all.

Bug fixes and refactoring

Previously, VyOS scripts that deal with Ethernet interfaces would parse the human-readable output of ethtool. That led to a complex implementation of serious bugs — up to commit errors with certain NICs (like in T6070). Fortunately, the version of ethtool we use in 1.4 supports JSON output, so now those scripts simply load JSON instead — the implementation is much simpler, and new bugs like that should not appear anymore.

There are more refactoring efforts and fixes — here's a full changelog for details.
