When daemon fails to load an authz plugin, it should be removed from
the plugin list. Else the plugin is retried on every request and
response, resulting in undesired behavior (eg. daemon panic)

containers may specify these cgroup values at runtime. This will allow
processes to change their priority to real-time within the container
when CONFIG_RT_GROUP_SCHED is enabled in the kernel. See #22380.
Also added sanity checks for the new --cpu-rt-runtime and --cpu-rt-period
flags to ensure that that the kernel supports these features and that
runtime is not greater than period.
Daemon will support a --cpu-rt-runtime flag to initialize the parent
cgroup on startup, this prevents the administrator from alotting runtime
to docker after each restart.
There are additional checks that could be added but maybe too far? Check
parent cgroups to ensure values are <= parent, inspecting rtprio ulimit
and issuing a warning.

Currently the plugins pkg allows a single handler. This assumption

plugingetter is indepedent of docker/docker packages, so it can be
moved to pkg. This is also necessary for authorization plugins (part of
pkg) to use pluginv2. The original path at plugin/getter will be
eventually removed, when external repos (eg. libnetwork) update their
import paths.

To use a deferred func to overwrite the returned error requires using
the 'named' error. So reuse err, instead of pipelineError. Also, the old
pipelineError will never be nil, since its executed before the error can
be set.

As part of making graphdrivers support pluginv2, a PluginGetter
interface was necessary for cleaner separation and avoiding import
cycles.
This commit creates a PluginGetter interface and makes pluginStore
implement it. Then the pluginStore object is created in the daemon
(rather than by the plugin manager) and passed to plugin init as
well as to the different subsystems (eg. graphdrivers, volumedrivers).
A side effect of this change was that some code was moved out of
experimental. This is good, since plugin support will be stable soon.

Writing the profile to /etc/apparmor.d, while also manually loading it
into the kernel results in quite a bit of confusion. In addition, it
means that people using apparmor but have /etc mounted read-only cannot
use apparmor at all on a Docker host.
Fix this by writing the profile to a temporary directory and deleting it
after it's been inserted.

This fix tries to address the issue raised in 25927 where
the HTTP headers have been chaged when AUthZ plugin is in
place.
This issue is that in `FlushAll` (`pkg/authorization/response.go`),
the headers have been written (with `WriteHeader`) before all the
headers have bee copied.
This fix fixes the issue by placing `WriteHeader` after.
A test has been added to cover the changes.`

if there is no cookie set in dm task, or flag DM_UDEV_DISABLE_LIBRARY_FALLBACK
is cleared for a DM_DEV_REMOVE task, libdevmapper will fallback to clean up the
symlink under /dev/mapper by itself, no matter the device removal is executed
immediately or deferred by the kernel.In some cases, the removal is deferred by the
kernel, while the symlink is deleted directly by libdevmapper, when docker tries to
activate the device again, the deferred removal will be canceld, but the symlink will
not show up again, so docker's attempt to mount the device by the symlink will fail,
and it will eventually leads to a `docker start/diff` error.

The namespace unshare+pivot root is not possible when running inside a

Docker-DCO-1.1-Signed-off-by: Phil Estes <estesp@linux.vnet.ibm.com>
If we are running in a user namespace, don't try to mknod as
it won't be allowed. libcontainer will bind-mount the host's
devices over files in the container anyway, so it's not needed.
The chrootarchive package does a chroot (without mounting /proc) before
its work, so we cannot check /proc/self/uid_map when we need to. So
compute it in advance and pass it along with the tar options.
