  • 3aaabe234   tcp buffer limitation: per-cgroup limit ... Browse Code »

    This patch uses the "tcp.limit_in_bytes" field of the kmem_cgroup to
    effectively control the amount of kernel memory pinned by a cgroup.

    This value is ignored in the root cgroup, and in all others,
    caps the value specified by the admin in the net namespaces'
    view of tcp_sysctl_mem.

    If namespaces are being used, the admin is allowed to set a
    value bigger than cgroup's maximum, the same way it is allowed
    to set pretty much unlimited values in a real box.

  • d1a4c0b37   tcp memory pressure controls ... Browse Code »

    This patch introduces memory pressure controls for the tcp
    protocol. It uses the generic socket memory pressure code
    introduced in earlier patches, and fills in the
    necessary data in cg_proto struct.
