fix lxc.mount.auto clearing
the way config_mount was structured, sending 'lxc.mount.auto = '

cgmanager: several fixes
These all fix various ways that cgroup actions could fail if an
unprivileged user's cgroup paths were not all the same for all
controllers.
1. in cgm_{g,s}et, use the right controller, not the first in the list,
to get the cgroup path.
2. when we pass 'all' to cgmanager for a ${METHOD}_abs, make sure that all
cgroup paths are the same. That isn't necessary for methods not
taking an absolute path, so split up the former
cgm_supports_multiple_controllers() function into two booleans, one
telling whether cgm supports it, and another telling us whether
cgm supports it AND all controller cgroup paths are the same.
3. separately, do_cgm_enter with abs=true couldn't work if all
cgroup paths were not the same. So just ditch that helper and
call lxc_cgmanager_enter() where needed, because the special
cases would be more complicated.

- make the default RUNTIME_PATH be /var/run instead of /run. On older

and attempt to create the dnsmasq.pid file in it, but this will fail when
SELinux is enabled because the directory will have the default_t type.
Newer systems have /var/run symlinked to /run so you get to the same place
in that case.

- Attempt to use cgmanager directly over dbus otherwise
- Fallback to cgroupfs
apparmor: make sure sysfs and securityfs are mounted when checking for mount feature
Otherwise the check will return false if securityfs was not mounted
by the container's configuration. In the past we let that quietly
proceed, but unconfined. Now that we restrict such container
starts, this caused lxc-test-apparmor to fail.
apparmor: improve behavior when kernel lacks mount restrictions (v2)
(Dwight, I took the liberty of adding your Ack but the code did
change a bit to continue passing the char *label from attach.
Tested that "lxc-start -n u1 -s lxc.aa_profile=p2; lxc-attach -n u1"
does attach you to the p2 profile)
Apparmor policies require mount restrictions to fullfill many of
their promises - for instance if proc can be mounted anywhere,
then 'deny /proc/sysrq-trigger w' prevents only accidents, not
malice.
The mount restrictions are not available in the upstream kernel.
We can detect their presence through /sys. In the past, when
we detected it missing, we would not enable apparmor. But that
prevents apparmor from helping to prevent accidents.
At the same time, if the user accidentaly boots a kernel which
has regressed, we do not want them starting the container thinking
they are more protected than they are.
This patch:
1. adds a lxc.aa_allow_incomplete = 1 container config flag. If
not set, then any container which is not set to run unconfined
will refuse to run. If set, then the container will run with
apparmor protection.
2. to pass this flag to the apparmor driver, we pass the container
configuration (lxc_conf) to the lsm_label_set hook.
3. add a testcase. To test the case were a kernel does not
provide mount restrictions, we mount an empty directory over
the /sys/kernel/security/apparmor/features/mount directory. In
order to have that not be unmounted in a new namespace, we must
test using unprivileged containers (who cannot remove bind mounts
which hide existing mount contents).
This idea came from Andy Lutomirski. Instead of using a
temporary directory for the pivot_root put-old, use "." both
for new-root and old-root. Then fchdir into the old root
temporarily in order to unmount the old-root, and finally
chdir back into our '/'.
Drop lxc.pivotdir from the lxc.container.conf manpage.
Warn when we see a lxc.pivotdir entry (but keep it in the
lxc.conf for now).
support use of 'all' containers when cgmanager supports it
Introduce a new list of controllers just containing "all".
Make the lists of controllers null-terminated.
If the cgmanager api version is high enough, use the 'all' controller
rather than walking all controllers, which should greatly reduce the
amount of dbus overhead. This will be especially important for
those going through a cgproxy.
Also remove the call to cleanup cgroups when a cgroup existed. That
usually fails (and failure is ignored) since the to-be-cleaned-up
cgroup is busy, but we shouldn't even be trying. Note this can
create for extra un-cleanedup cgroups, however it's better than us
accidentally removing a cgroup that someone else had created and was
about to use.

restore init as its sibling, not as its child. This was previously accomplished
essentially via luck :). CRIU now has a --restore-sibling option which forces

config: fix the handling of lxc.hook and hwaddrs in unexpanded config
And add a testcase.
The code to update hwaddrs in a clone was walking through the container
configuration and re-printing all network entries. However network
entries from an include file which should not be printed out were being
added to the unexpanded config. With this patch, at clone we simply
update the hwaddr in-place in the unexpanded configuration file, making
sure to make the same update to the expanded network configuration.
The code to update out lxc.hook statements had the same problem.
We also update it in-place in the unexpanded configuration, though
we mirror the logic we use when updating the expanded configuration.
(Perhaps that should be changed, to simplify future updates)
This code isn't particularly easy to review, so testcases are added
to make sure that (1) extra lxc.network entries are not added (or
removed), even if they are present in an included file, (2) lxc.hook
entries are not added, (3) hwaddr entries are updated, and (4)
the lxc.hook entries are properly updated (only when they should be).
When managing containers, I need to take action based on container
exit status. For instance, if it exited abnormally (status!=0), I
sometime want to respawn it automatically. Or, when invoking
`lxc-stop` I want to know if it terminated gracefully (ie on `SIGTERM`)
or on `SIGKILL` after a timeout.
This patch adds a new message type `lxc_msg_exit_code,` to preserve
ABI. It sends the raw status code as returned by `waitpid` so that
listening application may want to apply `WEXITSTATUS` before. This is
what `lxc-monitor` does.

lxc-cgm: fix issue with nested chowning
To ask cgmanager to chown files as an unpriv user, we must send the
request from the container's namespace (with our own userid also
mapped in). However when we create a new namespace then we must
open a new dbus connection, so that our credential and the credential
on the dbus socket match. Otherwise the proxy will refuse the request.
Because we were warning about this failure but not exiting, the failure
was not noticed until the unprivileged container went on to try to
administer its cgroups, i.e. creating a container inside itself.
Fix this by having the do_chown_cgroup create a new cgmanager connection.
In order to reduce the number of connections, since the list of subsystems
is global anyway, don't call do_chown_cgroup once for each controller,
just call it once and have it run over all controllers.
(This patch does not change the fact that we don't fail if the
chown failed. I think we should change that, but let's do it in a

Add support for checkpoint and restore via CRIU
This patch adds support for checkpointing and restoring containers via CRIU.
It adds two api calls, ->checkpoint and ->restore, which are wrappers around
the CRIU CLI. CRIU has an RPC API, but reasons for preferring exec() are
discussed in [1].
To checkpoint, users specify a directory to dump the container metadata (CRIU
dump files, plus some additional information about veth pairs and which
bridges they are attached to) into this directory. On restore, this
information is read out of the directory, a CRIU command line is constructed,
and CRIU is exec()d. CRIU uses the lxc-restore-net callback (which in turn
inspects the image directory with the NIC data) to properly restore the
network.
This will only work with the current git master of CRIU; anything as of a152c843 should work. There is a known bug where containers which have been
restored cannot be checkpointed [2].

Revert "chmod container dir to 0770"
This commit broke the testsuite for unprivileged containers as the
container directory is now 0750 with the owner being the container root
and the group being the user's group, meaning that the parent user can
only enter the directory, not create entries in there.
