5c9fc43e69 virsh: cmdAttachDisk: Don't assume type='block' if file can't be examined
'virsh attach-disk' uses stat() to determine if the 'source' is a
regular file. If stat fails though it assumes that the file is block.

Since it's way more common to have regular files and the detection does
not work at all when accessing a remote host, modify the default to
assume type='file' by default.

126cb34a20 virt-host-validate: fix detection with cgroups v2
Using virtCgroupNewSelf() is not correct with cgroups v2 because the
the virt-host-validate process is executed from from the same cgroup
context as the terminal and usually not all controllers are enabled
by default.

To do a proper check we need to use the root cgroup to see what
controllers are actually available. Libvirt or systemd ensures that
all controllers are available for VMs as well.

This still doesn't solve the devices controller with cgroups v2 where
there is no controller as it was replaced by eBPF. Currently libvirt
tries to query eBPF programs which usually works only for root as
regular users will get permission denied for that operation.

8a4343a436 vsh: Fix completion error in case of multiple mac addresses
We know that the bash completer automatically handle colon by preceding
it with an escape character backslash.
While our bash autompletion file vsh completes multiple items, In case
there're multiple items which have same prefix and the content of completion
items contain colon(say mac address), The vsh needs to correctly hands
the backslash which are added by bash completer, Otherwise the completion
won't be successful. This patch fixes this problem.

e.g.:

 # virsh domiflist --domain VM
 Interface   Type      Source    Model    MAC
-------------------------------------------------------------
 vnet0       network   default   virtio   52:54:00:fb:7b:f5
 vnet1       bridge    br0       virtio   52:54:00:80:1b:21

Before:
 # virsh detach-interface --domain VM --mac <TAB>
 # virsh detach-interface --domain VM --mac 52\:54\:00\:<TAB><TAB>

After:
 # virsh detach-interface --domain VM --mac <TAB>

53aec799fa Include vdpa devices in node device list
The current udev node device driver ignores all events related to vdpa
devices. Since libvirt now supports vDPA network devices, include these
devices in the device list.

Example output:

virsh # nodedev-list
[...ommitted long list of nodedevs...]
vdpa_vdpa0

virsh # nodedev-dumpxml vdpa_vdpa0
<device>
  <name>vdpa_vdpa0</name>
  <path>/sys/devices/vdpa0</path>
  <parent>computer</parent>
  <driver>
    <name>vhost_vdpa</name>
  </driver>
  <capability type='vdpa'>
    <chardev>/dev/vhost-vdpa-0</chardev>
  </capability>
</device>

NOTE: normally the 'parent' would be a PCI device instead of 'computer',
but this example output is from the vdpa_sim kernel module, so it
doesn't have a normal parent device.

08f8fd8413 conf: Add support for vDPA network devices
This patch adds new schema and adds support for parsing and formatting
domain configurations that include vdpa devices.

vDPA network devices allow high-performance networking in a virtual
machine by providing a wire-speed data path. These devices require a
vendor-specific host driver but the data path follows the virtio
specification.

When a device on the host is bound to an appropriate vendor-specific
driver, it will create a chardev on the host at e.g.  /dev/vhost-vdpa-0.
That chardev path can then be used to define a new interface with
type='vdpa'.

We no longer report any errors so all callers can be replaced by
virBitmapNew. Additionally virBitmapNew can't return NULL now so error

a79e7639da build: eliminate useless WITH_VIRTUALPORT check
WITH_VIRTUALPORT just checks that we are building on Linux and that
IFLA_PORT_MAX is defined in linux/if_link.h. Back when 802.11Qb[gh]
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.

caa9560c15 wireshark: Prefer ws_version.h over config.h
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.

Based on Andrea's original patch:

9e0ba037cd virshStreamInData: Handle block devices
This is very similar to previous commit.

The virshStreamInData() callback is used by virStreamSparseSendAll()
to detect whether the file the data is read from is in data or hole
section. The SendAll() will then send corresponding type of virStream
message to make server create a hole or write actual data. But the
callback uses virFileInData() even for block devices, which results in
an error. Just like in previous commit, emulate a DATA section
for block devices.

emulate being in data section all the time (vol-upload case).
Alternatively, we can't just lseek() beyond EOF with block
devices to create a hole, we will have to write zeroes
(vol-download case).  But to decide we need to know if the FD we
are reading data from / writing data to is a block device. Store
this information in _virshStreamCallbackData.

69980ab798 meson: Improve RPATH handling
Right now we're unconditionally adding RPATH information to the
installed binaries and libraries, but that's not always desired.

autotools seem to be smart enough to only include that information
when targeting a non-standard prefix, so most distro packages
don't actually contain it; moreover, both Debian and Fedora have
wiki pages encouraging packagers to avoid setting RPATH:

  https://wiki.debian.org/RpathIssue
  https://fedoraproject.org/wiki/RPath_Packaging_Draft

Implement RPATH logic that Does The Right Thing™ in the most
common cases, while still offering users the ability to override
the default behavior if they have specific needs.

tools: fix libvirt-guests.sh text assignments
In libvirt 6.6 stopping guests with libvirt-guests.sh is broken.
As soon as there is more than one guest one can see
`systemctl stop libvirt-guests` failing and in the log we see:
  libvirt-guests.sh[2455]: Running guests on default URI:
  libvirt-guests.sh[2457]: /usr/lib/libvirt/libvirt-guests.sh: 120:
      local: 2a49cb0f-1ff8-44b5-a61d-806b9e52dae2: bad variable name
  libvirt-guests.sh[2462]: no running guests.

That is due do mutliple guests becoming a list of UUIDs. Without
recognizing this as one single string the assignment breaks when using 'local'
(which was recently added in 6.3.0). This is because local is defined as
  local [option] [name[=value] ... | - ]
which makes the shell trying handle the further part of the string as
variable names. In the error above that string isn't a valid variable
name triggering the issue that is seen.

This depends on the shell being used. POSIX shells don't have 'local'
specified yet and for the common shells it depends. It worked in bash and
bash-in-POSIX-mode, but for example dash in POSIX mode triggers the issue.

To resolve that 'textify' all assignments that are strings or potentially
can become such lists (even if they are not using the local qualifier).
