This one is a problem because the most useful stat is a string and not a
float like verything else.  We may have to change the return type

8dc1d8b6c0 Avoid "invalid memory address or nil pointer dereference" panic
libcontainer.GetNamespace returns nil on FreeBSD because
libcontainer.namespaceList is empty. In this case, Namespaces#Get should
return nil instead of being panic.

Implement system.LUtimesNano and system.UtimesNano. The latter might be
removed in future because it's basically same as os.Chtimes. That's why
the test is mainly focusing LUtimesNano.

db1a117450 Fix libcontainer network support on rhel6
It seems that netlink in older kernels, including RHEL6, does not
support RTM_SETLINK with IFLA_MASTER. It just silently ignores it, reporting
no error, causing netlink.NetworkSetMaster() to not do anything yet
return no error.

We fix this by introducing and using AddToBridge() in a very similar manner
to CreateBridge(), which use the old ioctls directly.

This fixes https://github.com/dotcloud/docker/issues/4668

eab8c83391 In certain cases, setting the process label will not happen.
When the code attempts to set the ProcessLabel, it checks if SELinux Is
enabled.  We have seen a case with some of our patches where the code
is fooled by the container to think that SELinux is not enabled.  Calling
label.Init before setting up the rest of the container, tells the library that
SELinux is enabled and everything works fine.

c250bdad25 Remove hard coding of SELinux labels on systems without proper selinux policy.
If a system is configured for SELinux but does not know about docker or
containers, then we want the transitions of the policy to work.  Hard coding
the labels causes docker to break on older Fedora and RHEL systems

cba2eef566 Allow non-privileged containers to create device nodes.
Such nodes could already be created by importing a tarball to a container; now
they can be created from within the container itself.

This gives non-privileged containers the mknod kernel capability, and modifies
their cgroup settings to allow creation of *any* node, not just whitelisted
ones.  Use of such nodes is still controlled by the existing cgroup whitelist.
