+QEMU virtio-fs shared file system daemon
+========================================
+
+Synopsis
+--------
+
+**virtiofsd** [*OPTIONS*]
+
+Description
+-----------
+
+Share a host directory tree with a guest through a virtio-fs device. This
+program is a vhost-user backend that implements the virtio-fs device. Each
+virtio-fs device instance requires its own virtiofsd process.
+
+This program is designed to work with QEMU's ``--device vhost-user-fs-pci``
+but should work with any virtual machine monitor (VMM) that supports
+vhost-user. See the Examples section below.
+
+This program must be run as the root user. Upon startup the program will
+switch into a new file system namespace with the shared directory tree as its
+root. This prevents "file system escapes" due to symlinks and other file
+system objects that might lead to files outside the shared directory. The
+program also sandboxes itself using seccomp(2) to prevent ptrace(2) and other
+vectors that could allow an attacker to compromise the system after gaining
+control of the virtiofsd process.
+
+Options
+-------
+
+.. program:: virtiofsd
+
+.. option:: -h, --help
+
+ Print help.
+
+.. option:: -V, --version
+
+ Print version.
+
+.. option:: -d
+
+ Enable debug output.
+
+.. option:: --syslog
+
+ Print log messages to syslog instead of stderr.
+
+.. option:: -o OPTION
+
+ * debug -
+ Enable debug output.
+
+ * flock|no_flock -
+ Enable/disable flock. The default is ``no_flock``.
+
+ * log_level=LEVEL -
+ Print only log messages matching LEVEL or more severe. LEVEL is one of
+ ``err``, ``warn``, ``info``, or ``debug``. The default is ``info``.
+
+ * norace -
+ Disable racy fallback. The default is false.
+
+ * posix_lock|no_posix_lock -
+ Enable/disable remote POSIX locks. The default is ``posix_lock``.
+
+ * readdirplus|no_readdirplus -
+ Enable/disable readdirplus. The default is ``readdirplus``.
+
+ * source=PATH -
+ Share host directory tree located at PATH. This option is required.
+
+ * timeout=TIMEOUT -
+ I/O timeout in seconds. The default depends on cache= option.
+
+ * writeback|no_writeback -
+ Enable/disable writeback cache. The cache alows the FUSE client to buffer
+ and merge write requests. The default is ``no_writeback``.
+
+ * xattr|no_xattr -
+ Enable/disable extended attributes (xattr) on files and directories. The
+ default is ``no_xattr``.
+
+.. option:: --socket-path=PATH
+
+ Listen on vhost-user UNIX domain socket at PATH.
+
+.. option:: --fd=FDNUM
+
+ Accept connections from vhost-user UNIX domain socket file descriptor FDNUM.
+ The file descriptor must already be listening for connections.
+
+.. option:: --thread-pool-size=NUM
+
+ Restrict the number of worker threads per request queue to NUM. The default
+ is 64.
+
+.. option:: --cache=none|auto|always
+
+ Select the desired trade-off between coherency and performance. ``none``
+ forbids the FUSE client from caching to achieve best coherency at the cost of
+ performance. ``auto`` acts similar to NFS with a 1 second metadata cache
+ timeout. ``always`` sets a long cache lifetime at the expense of coherency.
+
+Examples
+--------
+
+Export ``/var/lib/fs/vm001/`` on vhost-user UNIX domain socket
+``/var/run/vm001-vhost-fs.sock``:
+
+::
+
+ host# virtiofsd --socket-path=/var/run/vm001-vhost-fs.sock -o source=/var/lib/fs/vm001
+ host# qemu-system-x86_64 \
+ -chardev socket,id=char0,path=/var/run/vm001-vhost-fs.sock \
+ -device vhost-user-fs-pci,chardev=char0,tag=myfs \
+ -object memory-backend-memfd,id=mem,size=4G,share=on \
+ -numa node,memdev=mem \
+ ...
+ guest# mount -t virtiofs myfs /mnt

+ * Intel IGD support
+ *
+ * Obviously IGD is not a discrete device, this is evidenced not only by it
+ * being integrated into the CPU, but by the various chipset and BIOS
+ * dependencies that it brings along with it. Intel is trying to move away
+ * from this and Broadwell and newer devices can run in what Intel calls
+ * "Universal Pass-Through" mode, or UPT. Theoretically in UPT mode, nothing
+ * more is required beyond assigning the IGD device to a VM. There are
+ * however support limitations to this mode. It only supports IGD as a
+ * secondary graphics device in the VM and it doesn't officially support any
+ * physical outputs.
+ *
+ * The code here attempts to enable what we'll call legacy mode assignment,
+ * IGD retains most of the capabilities we expect for it to have on bare
+ * metal. To enable this mode, the IGD device must be assigned to the VM
+ * at PCI address 00:02.0, it must have a ROM, it very likely needs VGA
+ * support, we must have VM BIOS support for reserving and populating some
+ * of the required tables, and we need to tweak the chipset with revisions
+ * and IDs and an LPC/ISA bridge device. The intention is to make all of
+ * this happen automatically by installing the device at the correct VM PCI
+ * bus address. If any of the conditions are not met, we cross our fingers
+ * and hope the user knows better.
+ *
+ * NB - It is possible to enable physical outputs in UPT mode by supplying
+ * an OpRegion table. We don't do this by default because the guest driver
+ * behaves differently if an OpRegion is provided and no monitor is attached
+ * vs no OpRegion and a monitor being attached or not. Effectively, if a
+ * headless setup is desired, the OpRegion gets in the way of that.
+ */
+
+/*
+ * This presumes the device is already known to be an Intel VGA device, so we
+ * take liberties in which device ID bits match which generation. This should
+ * not be taken as an indication that all the devices are supported, or even
+ * supportable, some of them don't even support VT-d.
+ * See linux:include/drm/i915_pciids.h for IDs.

- * Intel IGD support
- *
- * Obviously IGD is not a discrete device, this is evidenced not only by it
- * being integrated into the CPU, but by the various chipset and BIOS
- * dependencies that it brings along with it. Intel is trying to move away
- * from this and Broadwell and newer devices can run in what Intel calls
- * "Universal Pass-Through" mode, or UPT. Theoretically in UPT mode, nothing
- * more is required beyond assigning the IGD device to a VM. There are
- * however support limitations to this mode. It only supports IGD as a
- * secondary graphics device in the VM and it doesn't officially support any
- * physical outputs.
- *
- * The code here attempts to enable what we'll call legacy mode assignment,
- * IGD retains most of the capabilities we expect for it to have on bare
- * metal. To enable this mode, the IGD device must be assigned to the VM
- * at PCI address 00:02.0, it must have a ROM, it very likely needs VGA
- * support, we must have VM BIOS support for reserving and populating some
- * of the required tables, and we need to tweak the chipset with revisions
- * and IDs and an LPC/ISA bridge device. The intention is to make all of
- * this happen automatically by installing the device at the correct VM PCI
- * bus address. If any of the conditions are not met, we cross our fingers
- * and hope the user knows better.
- *
- * NB - It is possible to enable physical outputs in UPT mode by supplying
- * an OpRegion table. We don't do this by default because the guest driver
- * behaves differently if an OpRegion is provided and no monitor is attached
- * vs no OpRegion and a monitor being attached or not. Effectively, if a
- * headless setup is desired, the OpRegion gets in the way of that.

@section Related binaries
-@subsection qemu-nbd --partition (since 4.0.0)
-
-The ``qemu-nbd --partition $digit'' code (also spelled @option{-P})
-can only handle MBR partitions, and has never correctly handled
-logical partitions beyond partition 5. If you know the offset and
-length of the partition (perhaps by using @code{sfdisk} within the
-guest), you can achieve the effect of exporting just that subset of
-the disk by use of the @option{--image-opts} option with a raw
-blockdev using the @code{offset} and @code{size} parameters layered on
-top of any other existing blockdev. For example, if partition 1 is
-100MiB long starting at 1MiB, the old command:
-
-@code{qemu-nbd -t -P 1 -f qcow2 file.qcow2}
-
-can be rewritten as:
-
-@code{qemu-nbd -t --image-opts driver=raw,offset=1M,size=100M,file.driver=qcow2,file.backing.driver=file,file.backing.filename=file.qcow2}
-
-Alternatively, the @code{nbdkit} project provides a more powerful
-partition filter on top of its nbd plugin, which can be used to select
-an arbitrary MBR or GPT partition on top of any other full-image NBD
-export. Using this to rewrite the above example results in:
-
-@code{qemu-nbd -t -k /tmp/sock -f qcow2 file.qcow2 &}
-@code{nbdkit -f --filter=partition nbd socket=/tmp/sock partition=1}
-

+@subsection qemu-nbd --partition (removed in 5.0.0)
+
+The ``qemu-nbd --partition $digit'' code (also spelled @option{-P})
+could only handle MBR partitions, and never correctly handled logical
+partitions beyond partition 5. Exporting a partition can still be
+done by utilizing the @option{--image-opts} option with a raw blockdev
+using the @code{offset} and @code{size} parameters layered on top of
+any other existing blockdev. For example, if partition 1 is 100MiB
+long starting at 1MiB, the old command:
+
+@code{qemu-nbd -t -P 1 -f qcow2 file.qcow2}
+
+can be rewritten as:
+
+@code{qemu-nbd -t --image-opts driver=raw,offset=1M,size=100M,file.driver=qcow2,file.file.driver=file,file.file.filename=file.qcow2}

+""" Test description
+
+When performing a backup, all writes on the source subtree must go through the
+backup-top filter so it can copy all data to the target before it is changed.
+backup-top filter is appended above source node, to achieve this thing, so all
+parents of source node are handled. A configuration with side parents of source
+sub-tree with write permission is unsupported (we'd have append several
+backup-top filter like nodes to handle such parents). The test create an
+example of such configuration and checks that a backup is then not allowed
+(blockdev-backup command should fail).
+
+The configuration:
+
+ ┌────────┐ target ┌─────────────┐
+ │ target │ ◀─────── │ backup_top │
+ └────────┘ └─────────────┘
+ │
+ │ backing
+ ▼
+ ┌─────────────┐
+ │ source │
+ └─────────────┘
+ │
+ │ file
+ ▼
+ ┌─────────────┐ write perm ┌───────┐
+ │ base │ ◀──────────── │ other │
+ └─────────────┘ └───────┘
+
+On activation (see .active field of backup-top state in block/backup-top.c),
+backup-top is going to unshare write permission on its source child. Write
+unsharing will be propagated to the "source->base" link and will conflict with
+other node write permission. So permission update will fail and backup job will
+not be started.
+
+Note, that the only thing which prevents backup of running on such
+configuration is default permission propagation scheme. It may be altered by
+different block drivers, so backup will run in invalid configuration. But
+something is better than nothing. Also, before the previous commit (commit
+preceding this test creation), starting backup on such configuration led to
+crash, so current "something" is a lot better, and this test actual goal is
+to check that crash is fixed :)
