   * Original bug report

  Hey everyone,

  Current systemd versions all fail when the unified cgroup hierarchy is
  not-writable. This is especially problematic in containers where the
  systemd administrator might decide to not delegate the unified
  hierarchy or when running with a liblxc driver that doesn't yet know
  how to handle the unified cgroup hierarchy. I've pushed patches to
  systemd upstream that let systemd ingnore the non-delegated unified
  hierarchy. The relevant commits are:

  e07aefbd675b651f8d45b5fb458f2747b04d6e04
  2d56b80a1855836abf1d7458394c345ad9d55382
  1ff654e28b7b8e7d0a0be33522a84069ac6b07c0

  These patches will be in 236 but should be backported from xenial
  upwards.

[Touch-packages] [Bug 1734410] Re: systemd: handle undelegated cgroup2 hierarchy

[Christian Brauner]

If the systemd version doesn't support hybrid cgroup layout on xenial
then fine but I thought it did. But please make sure that Xenial doesn't
have anything mounted on /sys/fs/cgroup/unified.

[Touch-packages] [Bug 1734410] Re: systemd: handle undelegated cgroup2 hierarchy

[Dimitri John Ledkov]

I'm confused about this backport to xenial, given that xenial's mount-
setup.c does not try to neither mount nor use /sys/fs/cgroup/unified.

It wants to instead use /sys/fs/cgroup (for unified case).

And it has no capability to use hybrid cgroups.

Is this backport really needed back to xenial? I fear it may then
require backporting cg_is_hybrid_wanted aka hybrid cgroup support as
well.

[Touch-packages] [Bug 1734410] Re: systemd: handle undelegated cgroup2 hierarchy

[Christian Brauner]

Sorry for the brevity before. I tested this with systemd 23{5,6}
inside xenial and artful containers which is really the only case
where it matters.

A systemd with my patch applied would happily:
1. skip over undelegated /sys/fs/cgroup/unified mountpoints
   (e07aefbd675b651f8d45b5fb458f2747b04d6e04).
2. skip over undelegated pur cgroup2 mountpoints at /sys/fs/cgroup
   (2d56b80a1855836abf1d7458394c345ad9d55382)
3. remove any empty mountpoints created for case 1. and 2.
   (1ff654e28b7b8e7d0a0be33522a84069ac6b07c0)

Thanks for backporting these patches!

Next time, please provide some information about what and how was tested
when setting verification-done for an update. It is not enough to just
set the tag. The SRU team needs to be made aware of what has been tested
and how, if the test case was followed as expected. The more verbose the
better.

[Touch-packages] [Bug 1734410] Re: systemd: handle undelegated cgroup2 hierarchy

[Brian Murray]

Hello Christian, or anyone else affected,

Accepted systemd into artful-proposed. The package will build now and be
available at
https://launchpad.net/ubuntu/+source/systemd/234-2ubuntu12.3 in a few
hours, and then in the -proposed repository.

Please help us by testing this new package.  See
https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how
to enable and use -proposed.Your feedback will aid us getting this
update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug,
mentioning the version of the package you tested and change the tag from
verification-needed-artful to verification-done-artful. If it does not
fix the bug for you, please add a comment stating that, and change the
tag to verification-failed-artful. In either case, without details of
your testing we will not be able to proceed.

Further information regarding the verification process can be found at
https://wiki.ubuntu.com/QATeam/PerformingSRUVerification .  Thank you in
advance!

[Touch-packages] [Bug 1734410] Re: systemd: handle undelegated cgroup2 hierarchy

[Dimitri John Ledkov]

I'm slightly perplexed if this is needed in xenial or not.

Bug description:
  [Impact]

   * When a container is presented with a unified cgroup hierarchy,
  which is not properly delegated, systemd should not attempt (and fail)
  to use. This improves compatibility of xenial containers running on
  unified cgroup hierarchy hosts.

  [Test Case]

   * Xenial containers should boot, with non-writable unified cgroup
  hierarchy hosts.

  [Regression Potential]

   * unified cgroup hierarchy is not in use by default on xenial hosts,
  thus this is forward compatibility improvment with e.g. bionic hosts
  running xenial containers.

  [Other Info]
   
   * Original bug report

  Hey everyone,

  Current systemd versions all fail when the unified cgroup hierarchy is
  not-writable. This is especially problematic in containers where the
  systemd administrator might decide to not delegate the unified
  hierarchy or when running with a liblxc driver that doesn't yet know
  how to handle the unified cgroup hierarchy. I've pushed patches to
  systemd upstream that let systemd ingnore the non-delegated unified
  hierarchy. The relevant commits are:

  e07aefbd675b651f8d45b5fb458f2747b04d6e04
  2d56b80a1855836abf1d7458394c345ad9d55382
  1ff654e28b7b8e7d0a0be33522a84069ac6b07c0

  These patches will be in 236 but should be backported from xenial
  upwards.
