    VSOCK: Introduce VM Sockets · d021c344
    Andy King authored
    VM Sockets allows communication between virtual machines and the hypervisor.
    User level applications both in a virtual machine and on the host can use the
    VM Sockets API, which facilitates fast and efficient communication between
    guest virtual machines and their host.  A socket address family, designed to be
    compatible with UDP and TCP at the interface level, is provided.
    
    Today, VM Sockets is used by various VMware Tools components inside the guest
    for zero-config, network-less access to VMware host services.  In addition to
    this, VMware's users are using VM Sockets for various applications, where
    network access of the virtual machine is restricted or non-existent.  Examples
    of this are VMs communicating with device proxies for proprietary hardware
    running as host applications and automated testing of applications running
    within virtual machines.
    
    The VMware VM Sockets are similar to other socket types, like Berkeley UNIX
    socket interface.  The VM Sockets module supports both connection-oriented
    stream sockets like TCP, and connectionless datagram sockets like UDP. The VM
    Sockets protocol family is defined as "AF_VSOCK" and the socket operations
    split for SOCK_DGRAM and SOCK_STREAM.
    
    For additional information about the use of VM Sockets, please refer to the
    VM Sockets Programming Guide available at:
