NAME

       vmsock - vmware kernel module

SYNOPSIS

       modprobe vmsock

DESCRIPTION

       This  is  a  Linux  kernel  device  driver module that provides datagram and stream socket
       interfaces to the underlying VMCI device. The module implements a Linux socket family  and
       one  of  the  files  in  the  module,  vmci_sockets.h,  provides the various constants and
       functions necessary to create and, in the case of streams, connect sockets.

       When the module is loaded, /dev/vsock will be created with restricted permissions.  Access
       to  /dev/vsock  is  required  to use VMCI sockets, so it's recommended that permissions be
       relaxed via a udev policy file. For reference, the VMware Tools init  script  changes  the
       permissions of /dev/vsock to 666.

       Normally,  issuing  a  socket(2)  system  call  will  automatically load the kernel module
       providing that socket family, but as the vsock module is out-of-tree, there is no  in-tree
       socket  family  reservation  for  VMCI  sockets.  Before  sockets  are  created, userspace
       applications must call VMCISock_GetAFValue (defined in vmci_sockets.h) which will instruct
       the  vsock module to dynamically acquire a socket family reservation from the kernel. This
       function is implemented via ioctl(2) into the vsock module, so the vsock  module  must  be
       manually loaded by the user (perhaps using /etc/modules).

       The  vmci_sockets.h  header  should  be  installed in a system-wide location. We recommend
       /usr/include/vmci.

       The vsock module depends on symbols from the vmci module, and so the vmci module  must  be
       loaded first.

OPTIONS

       vmsock has no options.
