Weekly status #109

[tomp (Thomas Parrott)]

Weekly status for the weeks of the 29th July to the 4th of August.

Introduction

This past week was a relatively quiet one as we had several members of the team away.

The detailed release notes for LXC 3.2.1 and LXCFS 3.1.2 were made available.

On the LXD side, work continued on the internal rework of device handling with the the proxy device being moved over to the new common device interface framework.

Several limitations in the Bridged IP filtering feature were removed so that you can now use the IP filtering feature without having to use LXD’s built in DHCP server (dnsmasq) so long as you do specify the ipv4.address or ipv6.address fields statically on the device in LXD (and ensure the container configures its interface to use the same IP address).
