Subject: [PATCH 0/5] Networking cgroup controller

This patchset introduces a cgroup controller for the networking subsystem as a
whole. As of now, this controller will be used for:

* Limiting the specific ports that a process in a cgroup is allowed to bind
  to or listen on. For example, you can say that all the processes in a
  cgroup can only bind to ports 1000-2000, and listen on ports 1000-1100, which
  guarantees that the remaining ports will be available for other processes.

* Restricting which DSCP values processes can use with their sockets. For
  example, you can say that all the processes in a cgroup can only send
  packets with a DSCP tag between 48 and 63 (corresponding to TOS values of
  192 to 255).

* Limiting the total number of udp ports that can be used by a process in a
  cgroup. For example, you can say that all the processes in one cgroup are
  allowed to use a total of up to 100 udp ports. Since the total number of udp
  ports that can be used by all processes is limited, this is useful for
  rationing out the ports to different process groups.

In the future, more networking-related properties may be added to this
controller.

Anoop Naravaram (5):
  net: create the networking cgroup controller
  net: add bind/listen ranges to net cgroup
  net: add udp limit to net cgroup
  net: add dscp ranges to net cgroup
  net: add test for net cgroup
