VSOCK: Introduce VM Sockets
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.

+ tristate "Virtual Socket protocol"
+ help
+ Virtual Socket Protocol is a socket protocol similar to TCP/IP
+ allowing comunication between Virtual Machines and hypervisor
+ or host.
+ You should also select one or more hypervisor-specific transports
+ below.
+ To compile this driver as a module, choose M here: the module
+ will be called vsock. If unsure, say N.
+ tristate "VMware VMCI transport for Virtual Sockets"
+ depends on VSOCKETS && VMWARE_VMCI
+ help
+ This module implements a VMCI transport for Virtual Sockets.
+ Enable this transport if your Virtual Machine runs on a VMware
+ hypervisor.
+ To compile this driver as a module, choose M here: the module
+ will be called vmw_vsock_vmci_transport. If unsure, say N.
