a2455fd53d virt-aa-helper: use 'include if exists' on .files
Change the 'include' in the AppArmor policy to use 'include if exists'
when including <uuid>.files. Note that 'if exists' is only available
after AppArmor 3.0, therefore a #ifdef check must be added.

When the <uuid>.files is not present, there are some failures in the
AppArmor tools like the following, since they expect the file to exist
when using 'include':

ERROR: Include file /etc/apparmor.d/libvirt/libvirt-8534a409-a460-4fab-a2dd-0e1dce4ff273.files not found

220b2690da qemu: Default to TPM 2.0 in most scenarios
TPM 1.2 is a pretty bad default these days, especially for
architectures which were introduced when TPM 2.0 already existed.

We're already carving out exceptions for several scenarios, but
that's basically backwards: at this point, using TPM 1.2 is the
exception.

Restructure the code so that it reflects reality and we don't
have to remember to update it every time a new architecture is
introduced.

After this, there are still some functions left untouched because
they expect a different sentinel than NULL. Unfortunately, glib
does not provide macro for different sentinels. We may come up
with our own, but let's save that for future work.

We never release the reference on the GSource created for

main context if our thread is woken up prior to the wakeup
callback firing.

This can result in a leak of GSource objects, along with an
ever growing list of GSources attached to the main context,
which will gradually slow down execution of the loop, as
several operations are O(N) for the number of attached GSource
objects.

When attempting to run:

  libvirt.git/_build # ./run --selinux ./src/libvirtd

the following error is thrown:

  Refusing to change selinux context of file './src/libvirtd' outside build directory

which is obviously wrong. The problem is 'being inside of build
directory' is detected by simple progpath.startswith(builddir).
While builddir is an absolute path, progpath isn't necessarily.

And while looking into the code, I've noticed chcon() function
accessing variable outside its scope when printing out the path
it's working on.

When hot-plugging a FS device with un-assigned address with a bootindex
the recently-added validation check would fail as validation on hotplug
is done prior to address assignment.

To fix this problem we can simply relax the check to also pass on _NONE
addresses. Unsupported configurations will still be caught as previous
commit re-checks the definition after address assignment prior to
hotplug.

a57195e79e log_cleaner: Detect rotated filenames properly
When removing rotated log files, their name is matched against a

then parsed into an integer. Well, due to a bug in
virLogCleanerParseFilename() this is not how the code works. If
the suffix isn't found then g_match_info_fetch() returns an empty
string instead of NULL which then makes str2int parsing fail.
Just check for this case before parsing the string.

805b1eec7d qemu_hotplug: Clear QoS if required in qemuDomainChangeNet()
In one of my recent commits, I've introduced
virDomainInterfaceClearQoS() which is a helper that either calls
virNetDevBandwidthClear() ('tc' implementation) or
virNetDevOpenvswitchInterfaceClearQos() (for ovs ifaces). But I
made a micro optimization which leads to a bug: the function
checks whether passed iface has any QoS set and returns early if
it has none. In majority of cases this is right thing to do, but
when removing QoS on virDomainUpdateDeviceFlags() this is
problematic. The new definition (passed as argument to
virDomainInterfaceClearQoS()) contains no QoS (because user
requested its removal) and thus instead of removing the old QoS
setting nothing is done.

Fortunately, the fix is simple - pass olddev which contains the
old QoS setting.

957eea376b meson: Improve default firewall backend configuration
The current implementation requires users to configure the
preference as such:

  -Dfirewall_backend_default_1=iptables
  -Dfirewall_backend_default_2=nftables

In addition to being more verbose than one would hope, there
are several things that could go wrong.

First of all, meson performs no validation on the provided
values, so mistakes will only be caught by the compiler.
Additionally, it's entirely possible to provide nonsensical
combinations, such as repeating the same value twice.

Change things so that the preference can now be configured
as such:

  -Dfirewall_backend_priority=iptables,nftables

Checks have been added to prevent invalid values from being
accepted.

 - 9.1 machine type added
 - 'SierraForest' cpu type added
 - 'SapphireRapids-v3-x86_64-cpu' added
 - 'VFIO_MIGRATION' event added (and corresponding 'migration-events'
   bool for the device
 - 'exit-on-error' argument for 'migrate-incoming' added
 - 'sev-guest' gained 'legacy-vm-type' boolean
 - cpu topology added 'module' fields
 - 'compat-props' argument 'query-machines' added
 - 'deprecated-props' argument for 'query-cpu-model-expansion' added

Deprecated removals:
 - legacy non-shared-storage migration fully removed (config/stats)
 - legacy migration compression fully removed
 - RDMA support removed
 - dropped 'nios2' field type from 'query-cpus-fast' return data

Note that this dump was done on a newer kernel version which resulted in
the 'pcommit' feature being removed from the few test cases which depend
on the real CPU flag dump.

0a2508ee77 vsh: Don't crash when @text is NULL in vshCompleterFilter()
This can happen only for cmdComplete() in interactive mode (which
I'm still not convinced is any useful for users and whether we
should support it). Anyway, running plain 'complete' command with
no additional arguments boils down to @text being NULL in
vshReadlineParse() which handles the case just right but is then
subsequently passed to vshCompleterFilter() which isn't prepared
for this case.

f6ab0d5bdd vsh: Restore original rl_line_buffer after completion
Problem with readline is its API. It's basically a bunch of
global variables with no clear dependencies between them. In this
specific case that I'm seeing: in interactive mode the
cmdComplete() causes instant crash of virsh/virt-admin:

==27999== Invalid write of size 1
==27999==    at 0x516EF71: _rl_init_line_state (readline.c:742)
==27999==    by 0x5170054: rl_initialize (readline.c:1192)
==27999==    by 0x516E5E4: readline (readline.c:379)
==27999==    by 0x1B7024: vshReadline (vsh.c:3048)
==27999==    by 0x140DCF: main (virsh.c:905)
==27999==  Address 0x0 is not stack'd, malloc'd or (recently) free'd

This is because readline keeps a copy of pointer to
rl_line_buffer and the moment cmdComplete() returns and readline
takes over, it accesses the copy which is now a dangling pointer.

To fix this, just keep the original state of rl_line_buffer and
restore it.

e4afe64825 vsh: Close stderr among with stdin in cmdComplete
Our completer callbacks must refrain from printing anything onto
stderr, but unfortunately that's not how service code around
behaves. It may call vshError() and what not. Rather trying to
fix all possible paths (just consider opening a connection), just
close the stderr. We're already closing stdin.

6aa94ce105 bash-completion: Run virsh/virt-admin in quiet mode
In some cases (e.g. when virt-admin connects to the default URI)
some info message is printed onto stdout (using vshPrintExtra()).
This hurts user experience, just consider:

  virt-admin<TAB><TAB>
  NOTE\:\ Connecting\ to\ default\ daemon.\ Specify\ daemon\ using\ -c\ \(e.g.\ virtqemud\:///system\)

when no daemon is running. Suppress extra prints by passing '-q'
in the bash-completion script.
