For a couple of releases we have been warning
Encrypted images are deprecated
Support for them will be removed in a future release.
You can use 'qemu-img convert' to convert your image to an unencrypted one.
This warning was issued by system emulators, qemu-img, qemu-nbd
and qemu-io. Such a broad warning was issued because the original
intention was to rip out all the code for dealing with encryption
inside the QEMU block layer APIs.
The new block encryption framework used for the LUKS driver does
not rely on the unloved block layer API for encryption keys,
instead using the QOM 'secret' object type. It is thus no longer
appropriate to warn about encryption unconditionally.
When the qcow/qcow2 drivers are converted to use the new encryption
framework too, it will be practical to keep AES-CBC support present
for use in qemu-img, qemu-io & qemu-nbd to allow for interoperability
with older QEMU versions and liberation of data from existing encrypted
qcow2 files.
This change moves the warning out of the generic block code and
into the qcow/qcow2 drivers. Further, the warning is set to only
appear when running the system emulators, since qemu-img, qemu-io,
qemu-nbd are expected to support qcow2 encryption long term now that
the maint burden has been eliminated.

The python I/O tests helper for running qemu-img/qemu-io
setup stdout to be captured to a pipe, but left stderr
untouched. As a result, if something failed in qemu-img/
qemu-io, data written to stderr would get output directly
and not line up with data on the test stdout due to
buffering. If we explicitly redirect stderr to the same
pipe as stdout, things are much clearer when they go
wrong.

Writethrough mode is going to become a BlockBackend feature rather than
a BDS one, so forbid it in places where we won't be able to support it
when the code finally matches the envisioned design.
We only allowed setting the cache mode of non-root nodes after the 2.5
release, so we're still free to make this change.
The target of block jobs is now always opened in a writeback mode
because it doesn't have a BlockBackend attached. This makes more sense
anyway because block jobs know when to flush. If the graph is modified
on job completion, the original cache mode moves to the new root, so
for the guest device writethough always stays enabled if it was
configured this way.

This test is streaming to the top layer using the intermediate image
as the base. This is a mistake since block-stream never copies data
from the base image and its backing chain, so this is effectively a
no-op.
In addition to fixing the base parameter, this patch also writes some
data to the intermediate image before the test, so there's something
to copy and the test is meaningful.

Before this patch, blk_new() automatically assigned a name to the new
BlockBackend and considered it referenced by the monitor. This patch
removes the implicit monitor_add_blk() call from blk_new() (and
consequently the monitor_remove_blk() call from blk_delete(), too) and
thus blk_new() (and related functions) no longer take a BB name
argument.
In fact, there is only a single point where blk_new()/blk_new_open() is
called and the new BB is monitor-owned, and that is in blockdev_init().
Besides thus relieving us from having to invent names for all of the BBs
we use in qemu-img, this fixes a bug where qemu cannot create a new
image if there already is a monitor-owned BB named "image".
If a BB and its BDS tree are created in a single operation, as of this
patch the BDS tree will be created before the BB is given a name
(whereas it was the other way around before). This results in minor
change to the output of iotest 087, whose reference output is amended
accordingly.

The information which BB is concerned does not seem useful enough to
justify its existence in most other place (which may be related to qemu
printing the -drive parameter in question anyway, and for blockdev-add
the attribution is naturally unambiguous). Furthermore, as of a future
patch, bdrv_get_device_name(bs) will always return the empty string
before bdrv_open_inherit() returns.
Therefore, just dropping that information seems to be the best course of
action.

Just specifying a custom string is simpler in basically all places that
used it, and in addition, specifying the BB or node name is something we
generally do not do in other error messages when opening a BDS, so we
should not do it here.

The relative ordering of "device_del" return value and the
"DEVICE_DELETED" QMP event depends on the architecture being
tested. On x86 unplugging virtio disks is asynchronous
(=qdev_unplug()= → =hotplug_handler_unplug_request()=) while on s390x
it is synchronous (=qdev_unplug()= → =hotplug_handler_unplug()=). This
leads to the actual output on s390x consistently differing from the
reference output (that was probably produced on x86).
The easiest way to address this is to filter out QMP events in
067. The DEVICE_DELETED event is already getting explicitly tested by
the Python-based test case 139, so the test coverage should be
unaffected. Make use of the recently introduced _filter_qmp_events()
to remove QMP events from the test case output and adjust the
reference output accordingly.
The tr / sed / tr trick used for filtering was suggested by Max Reitz

With the new style protocol, the NBD client will currenetly
send NBD_OPT_EXPORT_NAME as the first (and indeed only)
option it wants. The problem is that the NBD protocol spec
does not allow for returning an error message with the
NBD_OPT_EXPORT_NAME option. So if the server mandates use
of TLS, the client will simply see an immediate connection
close after issuing NBD_OPT_EXPORT_NAME which is not user
friendly.
To improve this situation, if we have the fixed new style
protocol, we can sent NBD_OPT_LIST as the first option
to query the list of server exports. We can check for our
named export in this list and raise an error if it is not
found, instead of going ahead and sending NBD_OPT_EXPORT_NAME
with a name that we know will be rejected.
This improves the error reporting both in the case that the
server required TLS, and in the case that the client requested
export name does not exist on the server.
If the server does not support NBD_OPT_LIST, we just ignore
that and carry on with NBD_OPT_EXPORT_NAME as before.

For more complex BDS trees that can be created under normal circumstances,
we lose the ability to issue query commands because of our inability to
re-construct the absolute filename.
Instead, omit this field when it is a problem and present as much information
as we can.
This will change the expected output in iotest 110, where we will now see a
json filename and the lack of an absolute filename instead of an error.

Always report full_backing_filename, even if it's the same as
backing_filename. In the next patch, full_backing_filename may be
omitted if it cannot be generated instead of allowing e.g. drive_query
to abort if it runs into this scenario.
The presence or absence of the "full" field becomes useful information.

loader. If the s390-virtio-ccw machine finds no device to load from and
errors out, then emits a panic and exits the vm. This breaks test cases

Specifying the cache mode for a driver without a medium is not a useful
thing to do: As long as there is no medium, the cache mode doesn't make
a difference, and once the 'change' command is used to insert a medium,
it ignores the old cache mode and makes the new medium use
cache=writethrough.
Later patches will make it an error to specify the cache mode for an
empty drive. Remove the corresponding test case.

Creating an empty drive while specifying 'format' doesn't make sense.
The specified format driver would simply be ignored.
Make a set 'format' option an indication that a non-empty drive should

null-co/null-aio).

Our qapi conventions document that '.' should only be used in
the prefix of downstream names. BlkdebugEvent was a lone
exception to this. Changing this is not backwards compatible
to the 'blockdev-add' QMP command; however, that command is
not yet fully stable. It can also be argued that the testsuite
is the biggest user of blkdebug, and that any other user can
be taught to deal with the change by paying attention to
introspection results.

While in the long term we want throttling to be its own block filter
BDS, in the short term we want it to be part of the BB instead of a BDS;
even in the long term we may want legacy throttling to be automatically
tied to the BB.
blockdev-insert-medium and blockdev-remove-medium do not retain
throttling information in the BB (deliberately so). Therefore, using
them means tying this information to a BDS, which would break the model
described above. (The same applies to other flags such as
detect_zeroes.) We probably want to move this information to the BB or
its own filter BDS before blockdev-{insert,remove}-medium can be
considered completely stable.
Therefore, mark these functions experimental for the time being.

Commit 934659c switched the iotests to run qemu and qemu-nbd from a bash
subshell, in order to catch segfaults. Unfortunately, this means the
process PID cannot be captured via '$!'. We stopped killing qemu and
qemu-nbd processes, leaving a lot of orphaned, running qemu processes
after executing iotests.
Since the process is using exec in the subshell, the PID is the
same as the subshell PID.
Track these PIDs for cleanup using pidfiles in the $TEST_DIR. Only
track the qemu PID, however, if requested - not all usage requires
killing the process.
