  • Add wildcarded flow support in kernel datapath.

    Wildcarded flow can improve OVS flow set up performance by avoid sending
    matching new flows to the user space program. The exact performance boost
    will largely dependent on wildcarded flow hit rate.

    In case all new flows hits wildcard flows, the flow set up rate is
    within 5% of that of linux bridge module.

    Pravin has made significant contributions to this patch. Including API
    clean ups and bug fixes.

  • Currently OVS uses combination of genl and rtnl lock to protect
    datapath state. This was done due to networking stack locking.
    But this has complicated locking and there are few lock ordering
    issues with new tunneling protocols.
    Following patch simplifies locking by introducing new ovs mutex
    and now this lock is used to protect entire ovs state.

  • Until now, the optional OVS_USERSPACE_ATTR_USERDATA attribute had to be
    exactly 64 bits long, if it was present. However, 64 bits is not enough
    space to associate as much information with a flow as would be convenient
    for some userspace features now under development. This commit generalizes
    the attribute, allowing it to be any length.

    This generalization is backward-compatible: if userspace only uses 64-bit
    attributes, then it will not see any change in behavior.

  • It is a frequent mistake to confuse the netlink port identifier with a
    process identifier. Try to reduce this confusion by renaming fields
    that hold port identifiers portid instead of pid.

    I have carefully avoided changing the structures exported to
    userspace to avoid changing the userspace API.

    I have successfully built an allyesconfig kernel with this change.

  • Following patch adds support for network namespace to openvswitch.
    Since it must release devices when namespaces are destroyed, a
    side effect of this patch is that the module no longer keeps a
    refcount but instead cleans up any state when it is unloaded.

  • Open vSwitch is a multilayer Ethernet switch targeted at virtualized
    environments. In addition to supporting a variety of features
    expected in a traditional hardware switch, it enables fine-grained
    programmatic extension and flow-based control of the network.
    This control is useful in a wide variety of applications but is
    particularly important in multi-server virtualization deployments,
    which are often characterized by highly dynamic endpoints and the need
    to maintain logical abstractions for multiple tenants.

    The Open vSwitch datapath provides an in-kernel fast path for packet
    forwarding. It is complemented by a userspace daemon, ovs-vswitchd,
    which is able to accept configuration from a variety of sources and
    translate it into packet processing rules.

    See http://openvswitch.org for more information and userspace
    utilities.
