meson.build files choose whether to build modules based on foo.found()
expressions. If a feature is enabled (e.g. --enable-gtk), these expressions
are true even if the code is not used by any emulator, and this results
in an unexpected difference between modular and non-modular builds.
For non-modular builds, the files are not included in any binary, and
therefore the source files are never processed. For modular builds,
however, all .so files are unconditionally built by default, and therefore
a normal "make" tries to build them. However, the corresponding trace-*.h
files are absent due to this conditional:
if have_system
trace_events_subdirs += [
...
'ui',
...
]
endif
which was added to avoid wasting time running tracetool on unused trace-events
files. This causes a compilation failure; fix it by skipping module builds
entirely if (depending on the module directory) have_block or have_system
are false.

The GTK Clipboard implementation may cause guest hangs.
Therefore implement new configure switch: --enable-gtk-clipboard,
as a meson option disabled by default, which warns in the help
text about the experimental nature of the feature.
Regenerate the meson build options to include it.
The initialization of the clipboard is gtk.c, as well as the
compilation of gtk-clipboard.c are now conditional on this new
option to be set.

At present packaging the required DLLs of QEMU executables is a
manual process, and error prone.
Actually build/config-host.mak contains a GLIB_BINDIR variable
which is the directory where glib and other DLLs reside. This
works for both Windows native build and cross-build on Linux.
We can use it as the search directory for DLLs and automate
the whole DLL packaging process.

This patch adds support for asynchronously tearing down a VM on Linux.
When qemu terminates, either naturally or because of a fatal signal,
the VM is torn down. If the VM is huge, it can take a considerable
amount of time for it to be cleaned up. In case of a protected VM, it
might take even longer than a non-protected VM (this is the case on
s390x, for example).
Some users might want to shut down a VM and restart it immediately,
without having to wait. This is especially true if management
infrastructure like libvirt is used.
This patch implements a simple trick on Linux to allow qemu to return
immediately, with the teardown of the VM being performed
asynchronously.
If the new commandline option -async-teardown is used, a new process is
spawned from qemu at startup, using the clone syscall, in such way that
it will share its address space with qemu.The new process will have the
name "cleanup/<QEMU_PID>". It will wait until qemu terminates
completely, and then it will exit itself.
This allows qemu to terminate quickly, without having to wait for the
whole address space to be torn down. The cleanup process will exit
after qemu, so it will be the last user of the address space, and
therefore it will take care of the actual teardown. The cleanup
process will share the same cgroups as qemu, so both memory usage and
cpu time will be accounted properly.
If possible, close_range will be used in the cleanup process to close
all open file descriptors. If it is not available or if it fails, /proc
will be used to determine which file descriptors to close.
If the cleanup process is forcefully killed with SIGKILL before the
main qemu process has terminated completely, the mechanism is defeated
and the teardown will not be asynchronous.
This feature can already be used with libvirt by adding the following
to the XML domain definition to pass the parameter to qemu directly:
<commandline xmlns="http://libvirt.org/schemas/domain/qemu/1.0">
<arg value='-async-teardown'/>
</commandline>

The commit "Use io_uring_register_ring_fd() to skip fd operations" broke
when booting a guest with iothread and io_uring. That is because the
io_uring_register_ring_fd() call is made from the main thread instead of
IOThread where io_uring_submit() is called. It can not be guaranteed
to register the ring fd in the correct thread or unregister the same ring
fd if the IOThread is disabled. This optimization is not critical so we
will revert previous commit.
This reverts commit e2848bc574
and 77e3f038af.

Usually, we let upper layers handle CPU pinning, because
pthread_setaffinity_np() (-> sched_setaffinity()) is blocked via
seccomp when starting QEMU with
-sandbox enable=on,resourcecontrol=deny
However, we want to configure and observe the CPU affinity of threads
from QEMU directly in some cases when the sandbox option is either not
enabled or not active yet.
So let's add a way to configure CPU pinning via
qemu_thread_set_affinity() and obtain CPU affinity via
qemu_thread_get_affinity() and implement them under POSIX using
pthread_setaffinity_np() + pthread_getaffinity_np().
Implementation under Windows is possible using SetProcessAffinityMask()
+ GetProcessAffinityMask(), however, that is left as future work.

libblkio (https://gitlab.com/libblkio/libblkio/) is a library for
high-performance disk I/O. It currently supports io_uring,
virtio-blk-vhost-user, and virtio-blk-vhost-vdpa with additional drivers
under development.
One of the reasons for developing libblkio is that other applications
besides QEMU can use it. This will be particularly useful for
virtio-blk-vhost-user which applications may wish to use for connecting
to qemu-storage-daemon.
libblkio also gives us an opportunity to develop in Rust behind a C API
that is easy to consume from QEMU.
This commit adds io_uring, nvme-io_uring, virtio-blk-vhost-user, and
virtio-blk-vhost-vdpa BlockDrivers to QEMU using libblkio. It will be
easy to add other libblkio drivers since they will share the majority of
code.
For now I/O buffers are copied through bounce buffers if the libblkio
driver requires it. Later commits add an optimization for
pre-registering guest RAM to avoid bounce buffers.
The syntax is:
--blockdev io_uring,node-name=drive0,filename=test.img,readonly=on|off,cache.direct=on|off
--blockdev nvme-io_uring,node-name=drive0,filename=/dev/ng0n1,readonly=on|off,cache.direct=on
--blockdev virtio-blk-vhost-vdpa,node-name=drive0,path=/dev/vdpa...,readonly=on|off,cache.direct=on
--blockdev virtio-blk-vhost-user,node-name=drive0,path=vhost-user-blk.sock,readonly=on|off,cache.direct=on

Upon failure, a libseccomp API returns actual errno value very
rarely. Fortunately, after its commit 34bf78ab (contained in
2.5.0 release), the SCMP_FLTATR_API_SYSRAWRC attribute can be set
which makes subsequent APIs return true errno on failure.
This is especially critical when seccomp_load() fails, because

Since QEMU 7.1 we don't support Ubuntu 18.04 anymore, so the last big
important Linux distro that did not have a pre-packaged libslirp has
been dismissed. All other major distros seem to have a libslirp package
in their distribution already - according to repology.org:
Fedora 35: 4.6.1
CentOS 8 (RHEL-8): 4.4.0
Debian 11: 4.4.0
OpenSUSE Leap 15.3: 4.3.1
Ubuntu LTS 20.04: 4.1.0
FreeBSD Ports: 4.7.0
NetBSD pkgsrc: 4.7.0
Homebrew: 4.7.0
MSYS2 mingw: 4.7.0
The only one that was still missing a libslirp package is OpenBSD - but
the next version (OpenBSD 7.2 which will be shipped in October) is going
to include a libslirp package. Since QEMU 7.2 will be published after
OpenBSD 7.2, we should be fine there, too.
So there is no real urgent need for keeping the slirp submodule in
the QEMU tree anymore. Thus let's drop the slirp submodule now and
rely on the libslirp packages from the distributions instead.
