We were thinking here that there is a room for an RDMA cgroup. It would limit the amount of RDMA resources a container can use. It can also be used for the restrictions you mentioned, but maybe they are more suitable for a namespace. I'm not sure. In RoCE for instance, a restricted access to the GID table can be derived from the network namespace directly, but perhaps not in InfiniBand.
