An update to meson 0.61.1 meant that it started showing warnings due to the fact
that the default for run_command's 'check' parameter is going to change. It
unveiled the fact that we were even missing that parameter in some calls where
we expected different outcome. To make sure the behaviour does not change
specify the parameter explicitly. In places where we check for the return code
the parameter should be 'false' so that meson does not fail. In all other cases
the parameter should be set to 'true' to make sure possible failure also stops
meson.

While it's true that our virCommand subsystem is happy with
non-absolute paths, the dnsmasq capability code is not. It stores
the path to dnsmasq within and makes it accessible via
dnsmasqCapsGetBinaryPath(). While strictly speaking no caller
necessarily needs canonicalized path, let's find dnsmasq once and
cache the result.
Therefore, when constructing the capabilities structure look up
the binary path. If DNSMASQ already contains an absolute path
then virFindFileInPath() will simply return a copy.
With this code in place, the virFileIsExecutable() check can be
removed from dnsmasqCapsRefreshInternal() because
virFindFileInPath() already made sure the binary is executable.
But introducing virFindFileInPath() means we have to mock it in
test suite because dnsmasqCaps are created in
networkxml2conftest.
Moreover, we don't need to check for dnsmasq in configure.

Recently, FreeBSD has got sched_get/setaffinity(3) implementations and

users have to define _WITH_CPU_SET_T.
This breaks current detection. Specifically, meson sees the
sched_getaffinity() symbol and defines WITH_SCHED_GETAFFINITY. This
define unlocks Linux implementation of virProcessSetAffinity() and other
functions, which fails to build on FreeBSD because cpu_set_t is not
visible as _WITH_CPU_SET_T is not defined.
For now, change detection to the following:
- Instead of checking sched_getaffinity(), check if 'cpu_set_t' is
available through sched.h
- Explicitly check the sched.h header instead of assuming its presence
if WITH_SCHED_SETSCHEDULER is defined

There is no guarantee that QEMU and libvirt have been configured

In particular, Homebrew on macOS will pass a different, private

the files for a specific version appear in the usual locations.
This works perfectly fine as long as one package doesn't try to
go poking around another package's data - which is exactly what
libvirt needs to do in order to read and parse the QEMU interop
data.
qemu_datadir can now be explicitly provided to make this and

With the traditional libvirtd, the virConnectOpen call will probe active
drivers server side to find which one to use when the URI is NULL/empty.
With the modular daemons though, the remote client does not know which
daemon to connect in the first place, so we can't rely on virConnectOpen
probing. Currently the virtproxyd daemon has code to probe for a
possible driver by looking at which sockets are listening or which
binaries are installed. The remote client can thus connect to virtproxyd
which in turn can connect to a real hypervisor driver.
The virtproxyd probing code though isn't something that needs to live in
virtproxyd. By moving it into the remote client we can get probing
client side in all scenarios and avoid the extra trip via virtproxyd in
the common case.

Cloud-Hypervisor is a KVM virtualization using hypervisor. It
functions similarly to qemu and the libvirt Cloud-Hypervisor driver
uses a very similar structure to the libvirt driver.
The biggest difference from the libvirt perspective is that the
"monitor" socket is seperated into two sockets one that commands are
issued to and one that events are notified from. The current
implementation only uses the command socket (running over a REST API
with json encoded data) with future changes to add support for the
event socket (to better handle shutdowns from inside the VM).
This patch adds support for the following initial VM actions using the
Cloud-Hypervsior API:
* vm.create
* vm.delete
* vm.boot
* vm.shutdown
* vm.reboot
* vm.pause
* vm.resume
To use the Cloud-Hypervisor driver, the v15.0 release of
Cloud-Hypervisor is required to be installed.
Some additional notes:
* The curl handle is persistent but not useful to detect ch process
shutdown/crash (a future patch will address this shortcoming)
* On a 64-bit host Cloud-Hypervisor needs to support PVH and so can
emulate 32-bit mode but it isn't fully tested (a 64-bit kernel and
32-bit userspace is fine, a 32-bit kernel isn't validated)

with C code

1: -Wall

3: -Wall -Wextra -Wpedantic
Currently we add our extra warning flags unconditionally if the compiler
supports them, regardless of the meson warning_level setting. This has
effectively nullified the warning_level setting in meson, and also
results in meson printing these messages:
meson.build:498: WARNING: Consider using the built-in warning_level option instead of using "-Wall".
meson.build:498: WARNING: Consider using the built-in warning_level option instead of using "-Wextra".
Semantically we can think of our huge list of flags as being an "extra"
set of warnings, and thus we ought to only add them when meson would
itself use -Wextra. aka warning_level == 2 or 3.
In practice libvirt code can't be built with -Wpedantic so we can ignore
meson warning_level 3, and only add our flags when warning_level==2.
In doing this change, we no longer have to check -Wall/-Wextra ourselves

To support domUs with more than 4TB memory it is required to use
LIBXL_API_VERSION >= 0x040800, which uses uint64_t for certained guest
memory related quantities.
Unfortunately this change is not straight forward. While most of the
code in libxl.h handles the various LIBXL_API_VERSION variants
correctly, the check for valid a LIBXL_API_VERSION at the beginning of
the file was broken between Xen 4.7 and 4.13 - it did not cover for
API changes introduced in Xen 4.7 and 4.8. This was fixed with
xen-project/xen@c3999835df, which for libvirt means in practice either
the libxl API from Xen 4.5 or 4.13+ can be used.
This change uses pkgconfig to decide which API can be safely selected.
Xen provides a pkgconfig file since Xen 4.6, which is also the lowest
version expected by libvirt.

GLibC has a really complicated way of dealing with the 'stat' function
historically, which means our mocks in turn have to look at four
different possible functions to replace, stat, stat64, __xstat,
__xstat64.
In Fedora 33 and earlier:
- libvirt.so links to __xstat64
- libc.so library exports stat, stat64, __xstat, __xstat64
- sys/stat.h header exposes stat and __xstat
In Fedora 34 rawhide:
- libvirt.so links to stat64
- libc.so library exports stat, stat64, __xstat, __xstat64
- sys/stat.h header exposes stat
Historically we only looked at the exported symbols from libc.so to
decide which to mock.
In F34 though we must not consider __xstat / __xstat64 though because
they only existance for binary compatibility. Newly built binaries
won't reference them.
Thus we must introduce a header file check into our logic for deciding
which symbol to mock. We must ignore the __xstat / __xstat64 symbols
if they don't appear in the sys/stat.h header, even if they appear
in libc.so

This flag was originally created to indicate that either 1) the build
platform wasn't linux, 2) the build platform was linux, but the kernel
was too old to have macvtap support. Since there was already a switch
there, the ability to also disable it when 3) the kernel supports
macvtap but the user doesn't want it, was added in. I don't think that
(3) was ever an intentional goal, just something that grew naturally
out of having the flag there in the first place (unless possibly the
original author wanted a way to quickly disable their new code in case
it caused regressions elsewhere).
Now that the check for (2) has been removed, WITH_MACVTAP is just
checking (1) and (3), but (3) is pointless (because the extra code in
libvirt itself is miniscule, and the only external library needed for
it is libnl, which is also required for other unrelated features (and
itself has no subordinate dependencies and takes up < 1MB on
disk)). We can therfore eliminate the WITH_MACVTAP flag, as it is
functionally equivalent to WITH_LIBNL (which implies __linux__).

WITH_VIRTUALPORT just checks that we are building on Linux and that

support was added, the IFLA_* stuff was new (introduced in kernel
2.6.35, backported to RHEL6 2.6.32 kernel at some point), and so this
extra check was necessary, because libvirt was being built on Linux
distros that didn't yet have IFLA_* (e.g. older RHEL6, all
RHEL5). It's been in the kernel for a *very* long time now, so all
supported versions of all Linux platforms libvirt builds on have it.
Note that the above paragraph implies that the conditional compilation
should be changed to #if defined(__linux__). However, the astute
reader will notice that the code in question is sending and receiving
netlink messages, so it really should be conditional on WITH_LIBNL
(which implies __linux__) instead, so that's what this patch does.

There was one attempt a year ago done by me to drop HAL [1] but it was
never resolved. There was another time when Dan suggested to drop HAL
driver [2] but it was decided to keep it around in case device
assignment will be implemented for FreeBSD and the fact that
virt-manager uses node device driver [3].
I checked git history and code and it doesn't look like bhyve supports
device assignment so from that POV it should not block removing HAL.
The argument about virt-manager is not strong as well because libvirt
installed from FreeBSD packages doesn't have HAL support so it will not
affect these users as well [4].
The only users affected by this change would be the ones compiling
libvirt from GIT on FreeBSD.
I looked into alternatives and there is libudev-devd package on FreeBSD
but unfortunately it doesn't work as it doesn't list any devices when
used with libvirt. It provides libudev APIs using devd.
I also looked into devd directly and it provides some APIs but there are
no APIs for device monitoring and events so that would have to be
somehow done by libvirt.
Main motivation for dropping HAL support is to replace libdbus with GLib
dbus implementation and it cannot be done with HAL driver present in
libvirt because HAL APIs heavily depends on symbols provided by libdbus.

A wireshark plugin must declare what major and minor version it
was built with as these are checked when wireshark loads plugins.
On the top of that, we use major + minor + micro to adapt to
changed API between releases. So far, we were getting these
version numbers from wireshark/config.h.
And while most distributions install wireshark/config.h file some
don't. On distros shipping it it's hack^Wsaved during built by
packaging system and installed later. But some distros are not
doing that. At least not for new enough wireshark because as of
wireshark's commit v2.9.0~1273 the ws_version.h is installed
which contains the version macros we need and is installed by
wireshark itself.
But of course, some distros which have new enough wireshark
packaged do not ship ws_version.h and stick to the hack. That is
why we can't simply bump the minimal version and switch to the
new header file. We need a configure check and adopt our code to
deal with both ways. At least for the time being.

Commit <74416b1d4849ef77ef31de5344dd75f03094434b> added check for
rl_completion_quote_character to make sure we have correct readline
library. Commit <a9443bc9a9ef451b46306e66ed3b706756fc1414> added
inaccurate comment that it's a function.
We need to check for generic symbol instead of checking for function.
In addition the readline/readline.h file requires stdio.h to by included
beforehand which was done in autotools but I dropped it in meson.
And lastly the final condition to print error or disable readline was
broken as well by replacing the readline_dep every time if readline was
not explicitly enabled.

This changes the approach used with autotools where it was separate make
target. With meson it will be part of the `meson test` target but can be
disabled using --no-suite syntax-check or we can run only syntax-check
by using --suite syntax-check.

With meson we have to use both env vars and wrapper script to run python
with correct LANG settings.
run_command() and test() have 'env' attribute so we can use it, but
custom_target() doesn't support that attribute. Environment variables
cannot by configured using 'command' because meson checks if the first
item in the list is executable so we have to use a wrapper.
