Instead handle_buffered_iopage() is basically always returning true and

virtiofsd: Drop membership of all supplementary groups (CVE-2022-0358)
At the start, drop membership of all supplementary groups. This is
not required.
If we have membership of "root" supplementary group and when we switch
uid/gid using setresuid/setsgid, we still retain membership of existing
supplemntary groups. And that can allow some operations which are not
normally allowed.
For example, if root in guest creates a dir as follows.
$ mkdir -m 03777 test_dir
This sets SGID on dir as well as allows unprivileged users to write into
this dir.
And now as unprivileged user open file as follows.
$ su test
$ fd = open("test_dir/priviledge_id", O_RDWR|O_CREAT|O_EXCL, 02755);
This will create SGID set executable in test_dir/.
And that's a problem because now an unpriviliged user can execute it,
get egid=0 and get access to resources owned by "root" group. This is
privilege escalation.

python: move qmp utilities to python/qemu/utils

python/aqmp: add __del__ method to legacy interface
asyncio can complain *very* loudly if you forget to back out of things
gracefully before the garbage collector starts destroying objects that
contain live references to asyncio Tasks.
The usual fix is just to remember to call aqmp.disconnect(), but for the
sake of the legacy wrapper and quick, one-off scripts where a graceful
shutdown is not necessarily of paramount imporance, add a courtesy
cleanup that will trigger prior to seeing screenfuls of confusing
asyncio tracebacks.
Note that we can't *always* save you from yourself; depending on when
the GC runs, you might just seriously be out of luck. The best we can do
in this case is to gently remind you to clean up after yourself.

python: pin setuptools below v60.0.0
setuptools is a package that replaces the python stdlib 'distutils'. It
is generally installed by all venv-creating tools "by default". It isn't
actually needed at runtime for the qemu package, so our own setup.cfg
does not mention it as a dependency.
However, tox will create virtual environments that include it, and will
upgrade it to the very latest version. the 'venv' tool will also include
whichever version your host system happens to have.
Unfortunately, setuptools version 60.0.0 and above include a hack to
forcibly overwrite python's built-in distutils. The pylint tool that we
use to run code analysis checks on this package relies on distutils and
suffers regressions when setuptools >= 60.0.0 is present at all, see
https://github.com/PyCQA/pylint/issues/5704
Instruct tox and the 'check-dev' targets to avoid setuptools packages
that are too new, for now. Pipenv is unaffected, because setuptools 60
does not offer Python 3.6 support, and our pipenv config is pinned
against Python 3.6.

target/riscv: rvv-1.0: Add Zve32f support for scalar fp insns
Zve32f extension requires the scalar processor to implement the F
extension and implement all vector floating-point instructions for
floating-point operands with EEW=32 (i.e., no widening floating-point
operations).
