That mount hook predates the lxc.mount.auto = cgroup option.  So mention

Perhaps we should simply drop the mountcgroup hook from the tree, but
I'm not doing that in this patch.

The netdev->priv is shared for the netdev types.  A bad config file
could mix configuration for different types, resulting in a bad
netdev->priv when starting or even destroying a container.  So sanity
check the netdev->type before setting a netdev->priv element.

Currently do_reboot_and_check() is decreasing timeout variable even if
it is set to -1, so running 'lxc-stop --reboot --timeout=-1 ...' will

Also, there is no need to call gettimeofday if timeout is set to -1, so
these statements should be evaluated only when timeout is enabled.

New kernels require that to have privilege over a file, your
userns must have the old and new groups mapped into your userns.
So if a file is owned by our uid but another groupid, then we
have to chgrp the file to our primary group before we can try
(in a new user namespace) to chgrp the file to a group id in the
namespace.

But in some cases (when cloning) the file may already be mapped
into the container.  Now we cannot chgrp the file to our own
primary group - and we don't have to.

So detect that case.  Only try to chgrp the file to our primary
group if the file is owned by our euid (i.e. not by the container)
and the owning group is not already mapped into the container by
default.

With this patch, I'm again able to both create and clone containers
with no errors again.

This allows users to get/set cgroup settings when logged into a different
session than that from which they started the container.

There is no cgmanager command to do an _abs variant of cgmanager_get_value
and cgmanager_set_value.  So we fork off a new task, which enters the
parent cgroup of the started container, then can get/set the value from
there.  The reason not to go straight into the container's cgroup is that
if we are freezing the container, or the container is already frozen, we'll
freeze as well :)  The reason to fork off a new task is that if we are
in a cgroup which is set to remove-on-empty, we may not be able to return
to our original cgroup after making the change.
