963061dc11 virtiofsd: Add an option to enable/disable security label
Provide an option "-o security_label/no_security_label" to enable/disable
security label functionality. By default these are turned off.

If enabled, server will indicate to client that it is capable of handling
one security label during file creation. Typically this is expected to
be a SELinux label. File server will set this label on the file. It will
try to set it atomically wherever possible. But its not possible in
all the cases.

2720ceda05 docs: expand firmware descriptor to allow flash without NVRAM
The current firmware descriptor schema for flash requires that both the
executable to NVRAM template paths be provided. This is fine for the
most common usage of EDK2 builds in virtualization where the separate
_CODE and _VARS files are provided.

With confidential computing technology like AMD SEV, persistent storage
of variables may be completely disabled because the firmware requires a
known clean state on every cold boot. There is no way to express this
in the firmware descriptor today.

Even with regular EDK2 builds it is possible to create a firmware that
has both executable code and variable persistence in a single file. This
hasn't been commonly used, since it would mean every guest bootup would
need to clone the full firmware file, leading to redundant duplicate
storage of the code portion. In some scenarios this may not matter and
might even be beneficial. For example if a public cloud allows users to
bring their own firmware, such that the user can pre-enroll their own
secure boot keys, you're going to have this copied on disk for each
tenant already. At this point the it can be simpler to just deal with
a single file rather than split builds. The firmware descriptor ought
to be able to express this combined firmware model too.

This all points towards expanding the schema for flash with a 'mode'
concept:

 - "split" - the current implicit behaviour with separate files
   for code and variables.

 - "combined" - the alternate behaviour where a single file contains
   both code and variables.

 - "stateless" - the confidential computing use case where storage
   of variables is completely disable, leaving only the code.

111fbd74f6 qemu-img: Unify [-b [-F]] documentation
qemu-img convert documents the backing file and backing format options
as follows:
    [-B backing_file [-F backing_fmt]]
whereas qemu-img create has this:
    [-b backing_file] [-F backing_fmt]

That is, for convert, we document that -F cannot be given without -B,
while for create, way say that they are independent.

Indeed, it is technically possible to give -F without -b, because it is
left to the block driver to decide whether this is an error or not, so
sometimes it is:

$ qemu-img create -f qed -F qed test.qed 64M
Formatting 'test.qed', fmt=qed size=67108864 backing_fmt=qed [...]

And sometimes it is not:

$ qemu-img create -f qcow2 -F qcow2 test.qcow2 64M
Formatting 'test.qcow2', fmt=qcow2 cluster_size=65536 [...]
qemu-img: test.qcow2: Backing format cannot be used without backing file

Generally, it does not make much sense, though, and users should only
give -F with -b, so document it that way, as we have already done for
qemu-img convert (commit 1899bf4737).

95ea96e8b1 hw/arm/virt: KVM: Enable PAuth when supported by the host
Add basic support for Pointer Authentication when running a KVM
guest and that the host supports it, loosely based on the SVE
support.

Although the feature is enabled by default when the host advertises
it, it is possible to disable it by setting the 'pauth=off' CPU
property. The 'pauth' comment is removed from cpu-features.rst,
as it is now common to both TCG and KVM.

Tested on an Apple M1 running 5.16-rc6.

33973e1e1f hw/arm: add control knob to disable kaslr_seed via DTB
Generally a guest needs an external source of randomness to properly
enable things like address space randomisation. However in a trusted
boot environment where the firmware will cryptographically verify
components having random data in the DTB will cause verification to
fail. Add a control knob so we can prevent this being added to the
system DTB.

4ebb040f1f tests: integrate lcitool for generating build env manifests
This introduces

  https://gitlab.com/libvirt/libvirt-ci

as a git submodule at tests/lcitool/libvirt-ci

The 'lcitool' program within this submodule will be used to
automatically generate build environment manifests from a definition
of requirements in tests/lcitool/projects/qemu.yml

It will ultimately be capable of generating

 - Dockerfiles
 - Package lists for installation in VMs
 - Variables for configuring Cirrus CI environments

When a new build pre-requisite is needed for QEMU, if this package
is not currently known to libvirt-ci, it must first be added to the
'mappings.yml' file in the above git repo.

Then the submodule can be updated and the build pre-requisite added
to the tests/lcitool/projects/qemu.yml file. Now all the build env
manifests can be re-generated using  'make lcitool-refresh'

This ensures that when a new build pre-requisite is introduced, it
is added to all the different OS containers, VMs and Cirrus CI
environments consistently.

It also facilitates the addition of containers targetting new distros
or updating existing containers to new versions of the same distro,
where packages might have been renamed.

gtkdoc/kerneldoc style, and should be formatted with reST.

Note: I realize after the fact that I was implementing those modules
with sphinx 4, and that we have much lower requirements. Instead of
lowering the features and code (removing type annotations etc), let's
have a warning in the documentation when the D-Bus modules can't be
used, and point to the source XML file in that case.

26e8bed611 ppc: Mark the 'taihu' machine as deprecated
The PPC 405 CPU is a system-on-a-chip, so all 405 machines are very similar,
except for some external periphery. However, the periphery of the 'taihu'
machine is hardly emulated at all (e.g. neither the LCD nor the USB part had
been implemented), so there is not much value added by this board. The users
can use the 'ref405ep' machine to test their PPC405 code instead.

cd6b1674d6 docs: Fix botched rST conversion of 'submitting-a-patch.rst'
I completely botched up the merged[0] rST conversion of this document by
accidentally dropping entire hunks (!) of text. :-(  I made it very hard
for reviewers to spot it, as the omitted text was buried deep in the
document.  To fix my hatchet job, I reconverted the "SubmitAPatch"
wiki[1] page from scratch and replaced the existing rST with it, while
making sure I incorporated previous feedback.

In summary, in this reconverted edition:

- I did a careful (to the extent my eyes allowed) para-by-para
  comparison of the wiki and the rST to make sure I didn't omit
  anything accidentally.

- I made sure to work in the cosmetic feedback[2] that Thomas Huth
  pointed out in the merged (and botched) edition:

   - fix the hyperlinks in "Split up long patches"

   - replace ".". with "does not end with a dot" (in "Write a meaningful
     commit message" section)

   - replace "---" with ``---`` so that it doesn't render as an em-dash
     (there were two other occurrences; I fixed those too)

- Use "QEMU" spelling consistently in prose usage

- Add a consistent "refer to git-config" link where appropriate

Thanks to Thomas Huth and Alex Bennée for noticing it on IRC.  And sorry
for my sloppiness.

6b717a8d44 hw/misc/sifive_u_otp: Use IF_PFLASH for the OTP device instead of IF_NONE
Configuring a drive with "if=none" is meant for creation of a backend
only, it should not get automatically assigned to a device frontend.
Use "if=pflash" for the One-Time-Programmable device instead (like
it is e.g. also done for the efuse device in hw/arm/xlnx-zcu102.c).

Since the old way of configuring the device has already been published
with the previous QEMU versions, we cannot remove this immediately, but
have to deprecate it and support it for at least two more releases.

9f73de8df0 docs: rSTify the "SubmitAPatch" wiki
- The original wiki is here[1]. I copied the wiki source[2] into a .wiki
  file, and used `pandoc` to convert it to rST:

    $> pandoc -f Mediawiki -t rst submitting-a-patch.wiki -o
       submitting-a-patch.rst

- The only minor touch-ups I did was to fix URLs.  But 99%, it is a 1-1
  conversion.

  (An example of a "touch-up": under the section "Patch emails must
  include a Signed-off-by: line", I updated the "see SubmittingPatches
  1.12"  to "1.12) Sign your work")

- I have also converted a couple other related wiki pages (included in
  this patch series) that were hyperlinked within the SubmitAPatch page,
  or a page that it refers to:

  - SubmitAPullRequest: https://wiki.qemu.org/Contribute/SubmitAPullRequest
  - TrivialPatches: https://wiki.qemu.org/Contribute/TrivialPatches

- Over time, many people contributed to this wiki page; you can find all
  the authors in the wiki history[3].

d7c2e2b3f4 Jobs based on custom runners: add CentOS Stream 8
This introduces three different parts of a job designed to run
on a custom runner managed by Red Hat.  The goals include:

  a) propose a model for other organizations that want to onboard
     their own runners, with their specific platforms, build
     configuration and tests.

  b) bring awareness to the differences between upstream QEMU and the
     version available under CentOS Stream, which is "A preview of
     upcoming Red Hat Enterprise Linux minor and major releases".

  c) because of b), it should be easier to identify and reduce the gap
     between Red Hat's downstream and upstream QEMU.

The components of this custom job are:

  I) OS build environment setup code:

     - additions to the existing "build-environment.yml" playbook
       that can be used to set up CentOS/EL 8 systems.

     - a CentOS Stream 8 specific "build-environment.yml" playbook
       that adds to the generic one.

 II) QEMU build configuration: a script that will produce binaries with
     features as similar as possible to the ones built and packaged on
     CentOS stream 8.

III) Scripts that define the minimum amount of testing that the
     binaries built with the given configuration (point II) under the
     given OS build environment (point I) should be subjected to.

 IV) Job definition: GitLab CI jobs that will dispatch the build/test
     jobs (see points #II and #III) to the machine specifically
     configured according to #I.

4d8b0f0a95 docs: Deprecate incorrectly typed device_add arguments
While introducing a non-QemuOpts code path for device creation for JSON
-device, we noticed that QMP device_add doesn't check its input
correctly (accepting arguments that should have been rejected), and that
users may be relying on this behaviour (libvirt did until it was fixed
recently).

Let's use a deprecation period before we fix this bug in QEMU to avoid
nasty surprises for users.

1084159b31 qapi: deprecate drive-backup
Modern way is using blockdev-add + blockdev-backup, which provides a
lot more control on how target is opened.

As example of drive-backup problems consider the following:

User of drive-backup expects that target will be opened in the same
cache and aio mode as source. Corresponding logic is in
drive_backup_prepare(), where we take bs->open_flags of source.

It works rather bad if source was added by blockdev-add. Assume source
is qcow2 image. On blockdev-add we should specify aio and cache options
for file child of qcow2 node. What happens next:

drive_backup_prepare() looks at bs->open_flags of qcow2 source node.
But there no BDRV_O_NOCAHE neither BDRV_O_NATIVE_AIO: BDRV_O_NOCAHE is
places in bs->file->bs->open_flags, and BDRV_O_NATIVE_AIO is nowhere,
as file-posix parse options and simply set s->use_linux_aio.

The documentation is updated in a minimal way, so that drive-backup is
noted only as a deprecated command, and blockdev-backup used in most of
places.

2283b627bc tests/avocado: Rename avocado_qemu.Test -> QemuSystemTest
To run user-mode emulation tests, we introduced the
avocado_qemu.QemuUserTest which inherits from avocado_qemu.QemuBaseTest.
System-mode emulation tests are based on the avocado_qemu.Test class,
which also inherits avocado_qemu.QemuBaseTest. To avoid confusion,
rename it as avocado_qemu.QemuSystemTest.

bbbd9b6ec6 tests/acceptance: rename tests acceptance to tests avocado
In the discussion about renaming the `tests/acceptance` [1], the
conclusion was that the folders inside `tests` are related to the
framework running the tests and not directly related to the type of
the tests.

This changes the folder to `tests/avocado` and adjusts the MAKEFILE, the
CI related files and the documentation.

he relevant paragraph in docs/devel/build-system.rst, and take
the occasion to fix a preexisting confusion of *.h vs *.mak.

c11b3a1dd3 docs/sphinx: change default role to "any"
This interprets single-backtick syntax in all of our Sphinx docs as a
cross-reference to *something*, including Python symbols.

From here on out, new uses of `backticks` will cause a build failure if
the target cannot be referenced.

450e0f28a4 docs: remove non-reference uses of single backticks
The single backtick markup in ReST is the "default role". Currently,
Sphinx's default role is called "content". Sphinx suggests you can use
the "Any" role instead to turn any single-backtick enclosed item into a
cross-reference.

This is useful for things like autodoc for Python docstrings, where it's
often nicer to reference other types with `foo` instead of the more
laborious :py:meth:`foo`. It's also useful in multi-domain cases to
easily reference definitions from other Sphinx domains, such as
referencing C code definitions from outside of kerneldoc comments.

Before we do that, though, we'll need to turn all existing usages of the
"content" role to inline verbatim markup wherever it does not correctly
resolve into a cross-refernece by using double backticks instead.
