8e39542a03 vsh: Make positional parsing of arguments opt-in
Switch the command parser from using the VSH_OFLAG_REQ_OPT flag
opting out from positional parsing of arguments to a combination of the
'positional' flags for truly positional arguments and
'unwanted_positional' preserving semantics for the existing arguments
where the parser did it due to bad design.

This patch retires VSH_OFLAG_REQ_OPT along with the infrastructure that
was needed to refactor all uses properly.

100cbccecd virsh: Annodate 'unwanted_positional' arguments
Historically the command parser in virsh parses/fills even optional
arguments with values as if they were positional unless opted out using
VSH_OFLAG_REQ_OPT. This creates unexpected situations when commands can
break in this unwanted semantics:

 $ virsh snapshot-create-as --print-xml 1 2 3
 <domainsnapshot>
   <name>2</name>
   <description>3</description>
 </domainsnapshot>

To prevent any further addition annotate the rest of the arguments with
the 'unwanted_positional' flag, so that the parser can keep parsing them
as such but any further optional argument will not have this behaviour.

ac150162fd vsh: Annotate 'required' and 'positional' arguments explicitly
Add 'positional' and 'required' fields to vshCmdOptDef, which will
explicitly track the two properties of arguments.

To ensure that we have proper coverage, add checks to
vshCmddefCheckInternals validating the state of the above flags by
infering it from existing data.

This conversion will allow us:
 - remove VSH_OT_DATA in favor of VSH_OT_STRING
 - use VSH_OT_INT when required both as positional and non-positional
 - properly annotate which VSH_OT_ARGV are positional and which are not
   (currently inferred by whether an previous positional option exists)

cfcbba4c2b lib: Replace qsort() with g_qsort_with_data()
While glibc provides qsort(), which usually is just a mergesort,
until sorting arrays so huge that temporary array used by
mergesort would not fit into physical memory (which in our case
is never), we are not guaranteed it'll use mergesort. The
advantage of mergesort is clear - it's stable. IOW, if we have an
array of values parsed from XML, qsort() it and produce some
output based on those values, we can then compare the output with
some expected output, line by line.

But with newer glibc this is all history. After [1], qsort() is
no longer mergesort but introsort instead, which is not stable.
This is suboptimal, because in some cases we want to preserve
order of equal items. For instance, in ebiptablesApplyNewRules(),
nwfilter rules are sorted by their priority. But if two rules
have the same priority, we want to keep them in the order they
appear in the XML. Since it's hard/needless work to identify
places where stable or unstable sorting is needed, let's just
play it safe and use stable sorting everywhere.

Fortunately, glib provides g_qsort_with_data() which indeed
implement mergesort and it's a drop in replacement for qsort(),
almost. It accepts fifth argument (pointer to opaque data), that
is passed to comparator function, which then accepts three
arguments.

We have to keep one occurance of qsort() though - in NSS module
which deliberately does not link with glib.

e90d48ae6e virsh: Require --xpath for *dumpxml
Historically, the dumpxml command reject any unknown arguments,
for instance:

    virsh dumpxml fedora xxx

However, after v8.5.0-rc1~31 the second argument ('xxx') is
treated as an XPath, but it's not that clearly visible.
Therefore, require the --xpath switch, like this:

    virsh dumpxml fedora --xpath xxx

Yes, this breaks already released virsh, but I think we can argue
that the pool of users of this particular function is very small.
We also document the argument being mandatory:

   dumpxml [--inactive] [--security-info] [--update-cpu] [--migratable]
           [--xpath EXPRESSION] [--wrap] domain

The sooner we do this change, the better.

The same applies for other *dumpxml functions (net-dumpxml,
pool-dumpxml, vol-dumpxl to name a few).

8603b3d76c tools: add '--xpath EXPRESSION --wrap' args to all dumpxml commands
While you can chain the virsh output up to a later 'xmllint' or 'xpath'
command, integrating it into virsh avoids needs for installing extra
binaries which we've often found to be missing on production installs
of libvirt. It also gives better response if the initial virsh command
hits an error, as you don't get an aborted pipeline.

    $ virsh pool-dumpxml --xpath //permissions default
    <permissions>
      <mode>0711</mode>
      <owner>1000</owner>
      <group>1000</group>
      <label>unconfined_u:object_r:svirt_home_t:s0</label>
    </permissions>

If multiple nodes match, they are emitted individually:

    $ virsh dumpxml --xpath '//devices/*/address[@type="pci"]' --wrap demo
    <address type="pci" domain="0x0000" bus="0x05" slot="0x00" function="0x0"/>
    <address type="pci" domain="0x0000" bus="0x03" slot="0x00" function="0x0"/>
    ...snip...
    <address type="pci" domain="0x0000" bus="0x00" slot="0x02" function="0x0" multifunction="on"/>
    <address type="pci" domain="0x0000" bus="0x07" slot="0x00" function="0x0"/>

but if intending to post-process the output further, the results
can be wrapped in a parent node

    $ virsh dumpxml --xpath '//devices/*/address[@type="pci"]' --wrap demo
    <nodes>
      <address type="pci" domain="0x0000" bus="0x05" slot="0x00" function="0x0"/>
      <address type="pci" domain="0x0000" bus="0x03" slot="0x00" function="0x0"/>
      ...snip...
      <address type="pci" domain="0x0000" bus="0x00" slot="0x02" function="0x0" multifunction="on"/>
      <address type="pci" domain="0x0000" bus="0x07" slot="0x00" function="0x0"/>

c8238579fb lib: Drop internal virXXXPtr typedefs
Historically, we declared pointer type to our types:

  typedef struct _virXXX virXXX;
  typedef virXXX *virXXXPtr;

But usefulness of such declaration is questionable, at best.
Unfortunately, we can't drop every such declaration - we have to
carry some over, because they are part of public API (e.g.
virDomainPtr). But for internal types - we can do drop them and
use what every other C project uses 'virXXX *'.

This change was generated by a very ugly shell script that
generated sed script which was then called over each file in the

0415611fe0 nodedev: detect AP queues
Each AP card device can support upto 256 AP queues.  AP queues are
also detected by udev, so add support for libvirt nodedev driver.

7a2b898895 nodedev: detect AP card device
Introduce support for the Adjunct Processor (AP) crypto card device.
Udev already detects the device, so add support for libvirt nodedev
driver.

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.
