The bug is silly if you have a master/node cluster where node is on a
different machine than the master.
The current behavior is to give our addresses like "0.0.0.0:10101". If
you run "kubectl exec ..." from another host, that's not going to work
since on a different host 0.0.0.0 resolves to localhost and kubectl
exec fails with:
error: unable to upgrade connection: 404 page not found
This patch fixes the above by giving our correct addresses for reaching
from outside.

Some runtimes like Clear Containers need to interpret the CRI-O
annotations, to distinguish the infra container from the regular one.
Here we export those annotations and use a more standard dotted
namespace for them.

node-e2e tests were failing in RHEL because, if running a privileged
container, we get all capability in the spec. The spec generator wasn't
filtering caps based on actual host caps, it was just adding _everything_.
This patch makes spec generator host specific.

During "Port forwarding" e2e tests, the following panic happened:
```
panic: runtime error: invalid memory address or nil pointer dereference
[signal SIGSEGV: segmentation violation code=0x1 addr=0x0 pc=0x64981d]
goroutine 52788 [running]:

0xc4201cd0e0, ...)
```
The issue is `streamService.PortForward` assumed the first argument to
be the sandbox's infra container ID, thus trying to get it from memory
store using `.state.containers.Get`. Since that ID is of the sandbox
itself, it fails to get the container object from memory and panics in
`UpdateStatus`.
Fix it by looking for the sandbox's infra container ID starting from a
sandbox ID.

If we create a container using the image ID like
771cd5947d5ea4bf8e8f4900dd357dbb67e7b16486c270f8274087d182d457c6, then
a call to container_status will return that same ID for the "Image"
field in ContainerStatusResponse.
This patch matches dockershim behavior and return the first tagged name
if available from the image store.
This is also needed to fix a failure in k8s e2d tests.

When powering off the system, we want the ocid service, to shutdown
all containers running on the system so they can cleanup properly
This patch will cleanup all pods on poweroff.
The ocid-shutdown.service drops a file /var/run/ocid.shutdown when the system
is shutting down. The ocid-shutdown.service should only be executed at system
shutdown.
On bootup sequence should be
start ocid.service
start ocid-shutdown.service (This is a NO-OP)
On system shutdown
stop ocid-shutdown.service (Creates /var/run/ocid.shutdown)
stop ocid.service (Notices /var/run/ocid.service and stops all pods before exiting.)

Because kubelet will create broken symlinks for logPath it is necessary

Interleaving asynchronous updates with pod or container creations can
lead to unrecoverable races and corruptions of the pod or container hash
tables. This is fixed by serializing update against pod or container
creation operations, while pod and container creation operations can
run in parallel.

We need to support a 2x2 matrix of use cases with both
kubelet giving us (command, args) slices and the OCI
image config file giving us (ENTRYPOINT, CMD) slices.
Here we always prioritize the kubelet information over
the OCI image one, and use the latter when the former
is incomplete.
Not that this routine will be slightly simpler when
issue #395 is fixed.

When starting pods or containers, we create the mount points
first. It seems natural to do something symetrical when stopping
pods or containers, i.e. removing the mount point at last.
Also, the current logic may not work with VM based containers as the
hypervisor may hold a reference on the mount point while we're trying to
remove them.
Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
The way we build the OCI Process Args slice is incorrect.
With the current implementation we may for example end up building this
slice with only the entry point arguments, if the kubelet passed
information is missing the Command slice.
We also will end up building the Args slice with the Image config
process arguments, without the defined entry point, if kubelet does not
tell us anything about the container process command to be run.
This patch fixes that by favoring the kubelet ContainerConfig
information. If that is missing, we try to complete it with the
container image information. We always use ContainerConfig.Command[] or
ImageConfig.EntryPoint[] as the first OCI Process Args slice entries.
