-@table @description
-Pass-through security model in QEMU 9p server needs root privilege to do
-few file operations (like chown, chmod to any mode/uid:gid).  There are two
-issues in pass-through security model
-
-1) TOCTTOU vulnerability: Following symbolic links in the server could
-provide access to files beyond 9p export path.
-
-2) Running QEMU with root privilege could be a security issue.
-
-To overcome above issues, following approach is used: A new filesytem
-type 'proxy' is introduced. Proxy FS uses chroot + socket combination
-for securing the vulnerability known with following symbolic links.
-Intention of adding a new filesystem type is to allow qemu to run
-in non-root mode, but doing privileged operations using socket IO.
-
-Proxy helper(a stand alone binary part of qemu) is invoked with
-root privileges. Proxy helper chroots into 9p export path and creates
-a socket pair or a named socket based on the command line parameter.
-QEMU and proxy helper communicate using this socket. QEMU proxy fs
-driver sends filesystem request to proxy helper and receives the
-response from it.
-
-The proxy helper is designed so that it can drop root privileges except
-for the capabilities needed for doing filesystem operations.

-@c man begin OPTIONS
-The following options are supported:
-@table @option
-@item -h
-@findex -h
-Display help and exit
-@item -p|--path path
-Path to export for proxy filesystem driver
-@item -f|--fd socket-id
-Use given file descriptor as socket descriptor for communicating with
-qemu proxy fs drier. Usually a helper like libvirt will create
-socketpair and pass one of the fds as parameter to -f|--fd
-@item -s|--socket socket-file
-Creates named socket file for communicating with qemu proxy fs driver
-@item -u|--uid uid -g|--gid gid
-uid:gid combination to give access to named socket file
-@item -n|--nodaemon
-Run as a normal program. By default program will run in daemon mode
