selinux labels from request, not defaults Signed-off-by: Antonio Murdaca container_create: use sandbox's selinux if container's nil Signed-off-by: Antonio Murdaca sandbox: correctly init selinux labels First, we weren't correctly initializing selinux labels. If any of (level, user, role, type) was missing from kube selinux options, we were erroring out. This is wrong as kube sends just `level=s0` sometimes and docker itself allows `--security-opt label=level:s0`. This patch directly initializes selinux labels, correctly, and adds a test to verify it. Signed-off-by: Antonio Murdaca test: testdata: use container_runtime_t selinux type RHEL SELinux policy doesn't have `container_t` type but we're using it in our fixtures. That means Fedora integration tests pass because `container_t` is in Fedora's container policy but RHEL is broken. Fix it by using `container_runtime_t` which is aliased in Fedora policy to `container_t`.
