-QEMU 9p virtfs proxy filesystem helper
-======================================
-
-Synopsis
---------
-
-**virtfs-proxy-helper** [*OPTIONS*]
-
-Description
------------
-
-NOTE: The 9p 'proxy' backend is deprecated (since QEMU 8.1) and will be
-removed, along with this daemon, in a future version of QEMU!
-
-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:
-
-- TOCTTOU vulnerability: Following symbolic links in the server could
-  provide access to files beyond 9p export path.
-
-- Running QEMU with root privilege could be a security issue.
-
-To overcome above issues, following approach is used: A new filesystem
-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.
-
-Options
--------
-
-The following options are supported:
-
-.. program:: virtfs-proxy-helper
-
-.. option:: -h
-
-  Display help and exit
-
-.. option:: -p, --path PATH
-
-  Path to export for proxy filesystem driver
-
-.. option:: -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 this option.
-
-.. option:: -s, --socket SOCKET_FILE
-
-  Creates named socket file for communicating with qemu proxy fs driver
-
-.. option:: -u, --uid UID
-
-  uid to give access to named socket file; used in combination with -g.
-
-.. option:: -g, --gid GID
-
-  gid to give access to named socket file; used in combination with -u.
-
-.. option:: -n, --nodaemon
-
-  Run as a normal program. By default program will run in daemon mode
