When dropping backup-top, we need to drain the node before freeing the
BlockCopyState. Otherwise, requests may still be in flight and then the
assertion in shres_destroy() will fail.
(This becomes visible in intermittent failure of 056.)

bdrv_invalidate_cache_all() assumes that all nodes in a given subtree
are either active or inactive when it starts. Therefore, as soon as it
arrives at an already active node, it stops.
However, this assumption is wrong. For example, it's possible to take a
snapshot of an inactive node, which results in an active overlay over an
inactive backing file. The active overlay is probably also the root node
of an inactive BlockBackend (blk->disable_perm == true).
In this case, bdrv_invalidate_cache_all() does not need to do anything
to activate the overlay node, but it still needs to recurse into the
children and the parents to make sure that after returning success,
really everything is activated.

All paths that lead to bdrv_backup_top_drop(), except for the call
from backup_clean(), imply that the BDS AioContext has already been
acquired, so doing it there too can potentially lead to QEMU hanging
on AIO_WAIT_WHILE().
An easy way to trigger this situation is by issuing a two actions
transaction, with a proper and a bogus blockdev-backup, so the second
one will trigger a rollback. This will trigger a hang with an stack
trace like this one:

Fix this by not acquiring the AioContext there, and ensuring all paths
leading to it have it already acquired (backup_clean()).

Dirty map addition and removal functions are not acquiring to BDS
AioContext, while they may call to code that expects it to be
acquired.
This may trigger a crash with a stack trace like this one:

Fix this by acquiring the AioContext at qmp_block_dirty_bitmap_add()
and qmp_block_dirty_bitmap_add().

external_snapshot_abort() calls to bdrv_set_backing_hd(), which
returns state->old_bs to the main AioContext, as it's intended to be
used then the BDS is going to be released. As that's not the case when
aborting an external snapshot, return it to the AioContext it was
before the call.
This issue can be triggered by issuing a transaction with two actions,
a proper blockdev-snapshot-sync and a bogus one, so the second will
trigger a transaction abort. This results in a crash with an stack
trace like this one:

Issuing a blockdev-backup from qmp_blockdev_backup takes a slightly
different path than when it's issued from a transaction. In the code,
this is manifested as some redundancy between do_blockdev_backup() and
blockdev_backup_prepare().
This change unifies both paths, merging do_blockdev_backup() and
blockdev_backup_prepare(), and changing qmp_blockdev_backup() to
create a transaction instead of calling do_backup_common() direcly.
As a side-effect, now qmp_blockdev_backup() is executed inside a
drained section, as it happens when creating a blockdev-backup
transaction. This change is visible from the user's perspective, as
the job gets paused and immediately resumed before starting the actual
work.

In order to issue requests on an existing BlockBackend with the
'qemu-io' HMP command, allow specifying the BlockBackend not only with a
BlockBackend name, but also with a qdev ID/QOM path for a device that
owns the (possibly anonymous) BlockBackend.
Because qdev names could be conflicting with BlockBackend and node
names, introduce a -d option to explicitly address a device. If the
option is not given, a BlockBackend or a node is addressed.

Upstream: submitted, Message-Id: <20191205223339.764534-1-ehabkost@redhat.com>
When using `query-cpu-definitions` using `-machine none`,
QEMU is resolving all CPU models to their latest versions. The
actual CPU model version being used by another machine type (e.g.
`pc-q35-4.0`) might be different.
In theory, this was OK because the correct CPU model
version is returned when using the correct `-machine` argument.
Except that in practice, this breaks libvirt expectations:
libvirt always use `-machine none` when checking if a CPU model
is runnable, because runnability is not expected to be affected
when the machine type is changed.
For example, when running on a Haswell host without TSX,
Haswell-v4 is runnable, but Haswell-v1 is not. On those hosts,
`query-cpu-definitions` says Haswell is runnable if using
`-machine none`, but Haswell is actually not runnable using any
of the `pc-*` machine types (because they resolve Haswell to
Haswell-v1). In other words, we're breaking the "runnability
guarantee" we promised to not break for a few releases (see
qemu-deprecated.texi).
To address this issue, change the default CPU model version to v1
on all machine types, so we make `query-cpu-definitions` output
when using `-machine none` match the results when using `pc-*`.
This will change in the future (the plan is to always return the
latest CPU model version if using `-machine none`), but only
after giving libvirt the opportunity to adapt.

We have several almost identical copies of a blockdev_create() function
in different test cases. Time to create one unified function in
iotests.py.
To keep the diff managable, this patch only creates the function and
follow-up patches will convert the individual test cases.

RH-Acked-by: Stefan Hajnoczi <stefanha@redhat.com>
Includes the following tests:
- Adding a dirty bitmap.
* RHBZ: 1782175
- Starting a drive-mirror to an NBD-backed target.
* RHBZ: 1746217, 1773517
- Aborting an external snapshot transaction.
* RHBZ: 1779036
- Aborting a blockdev backup transaction.
* RHBZ: 1782111
For each one of them, a VM with a number of disks running in an
IOThread AioContext is used.

O-Subject: [RHEL-AV-8.2.0 qemu-kvm PATCH v2 6/6] iotests.py: Let wait_migration wait even more
Bugzilla: 1781637
RH-Acked-by: Sergio Lopez Pascual <slp@redhat.com>
RH-Acked-by: Max Reitz <mreitz@redhat.com>
RH-Acked-by: Stefan Hajnoczi <stefanha@redhat.com>
From: Max Reitz <mreitz@redhat.com>
The "migration completed" event may be sent (on the source, to be
specific) before the migration is actually completed, so the VM runstate
will still be "finish-migrate" instead of "postmigrate". So ask the
users of VM.wait_migration() to specify the final runstate they desire
and then poll the VM until it has reached that state. (This should be
over very quickly, so busy polling is fine.)
Without this patch, I see intermittent failures in the new iotest 280
under high system load. I have not yet seen such failures with other
iotests that use VM.wait_migration() and query-status afterwards, but
maybe they just occur even more rarely, or it is because they also wait
on the destination VM to be running.

target/arm/monitor: query-cpu-model-expansion crashed qemu when using machine type none
Commit e19afd566781 mentioned that target-arm only supports queryable
cpu models 'max', 'host', and the current type when KVM is in use.
The logic works well until using machine type none.
For machine type none, cpu_type will be null if cpu option is not
set by command line, strlen(cpu_type) will terminate process.
So We add a check above it.
This won't affect i386 and s390x since they do not use current_cpu.
