Weekly status #3

Weekly status for the week of the 19th to the 25th of June 2017.


This week was a bit less busy than usual due to half the team taking some well deserved vacation time and the LXD 2.15 release being just around the corner.

Conferences and talks

Christian Brauner (@brauner) presented LXD at Tübix (Tübingen, Germany).

Part of the LXD team will be travelling to Los Angeles, CA in September for the Open Source Summit, the Linux Security Summit and the Linux Plumbers Conference.

As part of that, we’ll be giving the following talks:

Ongoing projects

The list below is feature or refactoring work which will span several weeks/months and can’t be tied directly to a single Github issue or pull request.

Upstream changes

The items listed below are highlights of the work which happened upstream over the past week and which will be included in the next release.



  • Implement version 2 of the new network parser
    We’ve discussed the new network parser we’ve merged last week again in more detail and we realized that some existing use-cases we’re currently supporting in the old network parser would be broken by the new parser. As we’ve pointed out many times before, we’re strongly committed to backwards compatibility and not breaking existing use-cases. That’s why we decided to take a new approach. Instead of trying to mangle the old parser and new parser to come up with something that allows a smooth transition we will simply deprecate the old lxc.network.* configuration keys and replace them with lxc.net*. keys. We will start marking lxc.network.* keys deprecated with LXC 2.1 and completely remove them with LXC 3.0. In the meantime we will support the full-blown old legacy parser and the new network parser.
  • Fixed a memory leak in the tty handling code.
  • Update the Japanese translation of the manpages.
  • Correctly detect blocked signals in a process blocked signal mask (https://github.com/lxc/lxc/pull/1628, https://github.com/lxc/lxc/pull/1630).
  • Correctly generate lxc.pc prefix.
  • Fix a memory leak in attach code.
  • More work on preparing LXC 2.1.
  • Made the Centos template default to version 7.
  • Fixed arm64 detection in the Debian template.
  • Fixed support for non-x86 architectures in the Centos template.


Distribution work

This section is used to track the work done in downstream Linux distributions to ship the latest LXC, LXD and LXCFS as well as work to get various software to work properly inside containers.


  • LXD was updated in Ubuntu to cherry-pick the image direct download fix.
  • LXCFS was updated in Ubuntu to cherry-pick the btime revert (fixes “ps” start time).
  • LXC 1.0.10 was pushed to users of Ubuntu 14.04 LTS.
  • LXD 2.0.10 was pushed to users of Ubuntu 16.04 LTS.
  • LXC 2.0.8 was pushed to users of Ubuntu 16.04 LTS, Ubuntu 16.10 and Ubuntu 17.04.


  • Update to cherry-pick the LXD image direct download fix.
  • Update to cherry-pick the LXCFS btime fix.
  • The snap now bumps the inotify instances limit to 1024 (if currently below 1024).
