Michal Privoznik bab44aa963 qemu_migration: Unregister close callback only if connection still exists
When doing a peer-to-peer migration it may happen that the
connection to the destination disappears. If that happens,
there's no point in trying to unregister the close callback
because the connection is closed already. It results only in
polluting logs with this message:

  error : virNetSocketReadWire:1814 : End of file while reading data: : Input/output error

and the reason for that is unregistering a connection callback
results in RPC (among other things).

Jiri Denemark 364995ed57 qemu: Signal domain condition in qemuProcessStop a bit later
Signaling the condition before vm->def->id is reset to -1 is dangerous:
in case a waiting thread wakes up, it does not see anything interesting
(the domain is still marked as running) and just enters virDomainObjWait
where it waits forever because the condition will never be signalled
again.

Originally it was impossible to get into such situation because the vm
object was locked all the time between signaling the condition and
resetting vm->def->id, but after commit 860a999802 released in 6.8.0,
qemuDomainObjStopWorker called in qemuProcessStop between
virDomainObjBroadcast and setting vm->def->id to -1 unlocks the vm
object giving other threads a chance to wake up and possibly hang.

In real world, this can be easily reproduced by killing, destroying, or
just shutting down (from the guest OS) a domain while it is being
migrated somewhere else. The migration job would never finish.

So let's make sure we delay signaling the domain condition to the point
when a woken up thread can detect the domain is not active anymore.

Tim Wiederhake 370ac3d25c virThreadPoolNewFull: Prevent expanding worker pool by zero
On libvirtd startup, the list of priority worker threads is uninitialized
(`pool->prioWorkers` is NULL), and then "expanded" to zero (`prioWorkers`)
entries.

This causes `virThreadPoolExpand` to call `VIR_EXPAND_N` on a null pointer
and an increment of zero. The zero increment triggers `virReallocN` to not
actually allocate any memory and leave the pointer NULL, which, eventually,
causes `memset(NULL, 0, 0)` to be called in `virExpandN`.

`memset` is declared `__attribute__ ((__nonnull__ 1))`, which triggers the
following warning when libvirt is compiled with address sanitizing enabled:

    $ meson -Dbuildtype=debug -Db_lundef=false -Db_sanitize=address,undefined
    build && ninja -C build
    $ ./build/run build/src/libvirtd

Jonathon Jongsma 51fbbfdce8 nodedev: fix parent device of inactive mdevs
Inactive mdevs were simply formatting their parent name as the value
received from mdevctl rather than looking up the libvirt nodedev name of
the parent device. This resulted in a parent value of e.g.
'0000:5b:00.0' instead of 'pci_0000_5b_00_0'. This prevented defining a
new mdev device from the output of nodedev-dumpxml.

Unfortunately, it's not simple to fix this comprehensively due to the
fact that mdevctl supports defining (inactive) mdevs for parent devices
that do not actually exist on the host (yet). So for those persistent
mdev definitions that do not have a valid parent in the device list, the
parent device will be set to the root "computer" device.

Unfortunately, because the value of the 'parent' field now depends on
the configuration of the host, the mdevctl parsing test will output
'computer' for all test devices. Fixing this would require a more
extensive mock test environment.
