The further change of moving backup to be a one block-copy call will

The further change of moving backup to be a one block-copy call will
make copying chunk-size and cluster-size two separate things. So, even
with 64k cluster sized qcow2 image, default chunk would be 1M.
185 test however assumes, that with speed limited to 64K, one iteration
would result in offset=64K. It will change, as first iteration would
result in offset=1M independently of speed.
So, let's explicitly specify, what test wants: set max-chunk to 64K, so
that one iteration is 64K. Note, that we don't need to limit
max-workers, as block-copy rate limiter will handle the situation and
wouldn't start new workers when speed limit is obviously reached.

If main job coroutine called job_yield (while some background process
is in progress), we should give it a chance to call job_pause_point().
It will be used in backup, when moved on async block-copy.
Note, that job_user_pause is not enough: we want to handle
child_job_drained_begin() as well, which call job_pause().
Still, if job is already in job_do_yield() in job_pause_point() we
should not enter it.
iotest 109 output is modified: on stop we do bdrv_drain_all() which now
triggers job pause immediately (and pause after ready is standby).

Issuing 'stop' on the VM drains all nodes. If the mirror job has many
large requests in flight, this may lead to significant I/O that looks a
bit like 'stop' would make the job try to complete (which is what 129
should verify not to happen).
We can limit the I/O in flight by limiting the buffer size, so mirror
will make very little progress during the 'stop' drain.
(We do not need to do anything about commit, which has a buffer size of
512 kB by default; or backup, which goes cluster by cluster. Once we
have asynchronous requests for backup, that will change, but then we can
fine-tune the backup job to only perform a single request on a very
small chunk, too.)

Before this patch, test_block_commit() performs an active commit, which
under the hood is a mirror job. If we want to test various different
block jobs, we should perhaps run an actual commit job instead.
Doing so requires adding an overlay above the source node before the
commit is done (and then specifying the source node as the top node for
the commit job).

@busy is false when the job is paused, which happens all the time
because that is how jobs yield (e.g. for mirror at least since commit
565ac01f8d).
Back when 129 was added (2015), perhaps there was no better way of
checking whether the job was still actually running. Now we have the
@status field (as of 58b295ba52, i.e. 2018), which can give us exactly

Instead of checking iotests.py only, check all Python files in the
qemu-iotests/ directory. Of course, most of them do not pass, so there
is an extensive skip list for now. (The only files that do pass are
209, 254, 283, and iotests.py.)
(Alternatively, we could have the opposite, i.e. an explicit list of
files that we do want to check, but I think it is better to check files
by default.)
Unless started in debug mode (./check -d), the output has no information
on which files are tested, so we will not have a problem e.g. with
backports, where some files may be missing when compared to upstream.
Besides the technical rewrite, some more things are changed:
- For the pylint invocation, PYTHONPATH is adjusted. This mirrors
setting MYPYPATH for mypy.
- Also, MYPYPATH is now derived from PYTHONPATH, so that we include
paths set by the environment. Maybe at some point we want to let the
check script add '../../python/' to PYTHONPATH so that iotests.py does
not need to do that.
- Passing --notes=FIXME,XXX to pylint suppresses warnings for TODO
comments. TODO is fine, we do not need 297 to complain about such
comments.
- The "Success" line from mypy's output is suppressed, because (A) it
does not add useful information, and (B) it would leak information
about the files having been tested to the reference output, which we
decidedly do not want.

There are a couple of environment variables that we fetch with
os.environ.get() without supplying a default. Clearly they are required
and expected to be set by the ./check script (as evidenced by
execute_setup_common(), which checks for test_dir and
qemu_default_machine to be set, and aborts if they are not).
Using .get() this way has the disadvantage of returning an Optional[str]
type, which mypy will complain about when tests just assume these values
to be str.
Use [] instead, which raises a KeyError for environment variables that
are not set. When this exception is raised, catch it and move the abort
code from execute_setup_common() there.
Drop the 'assert iotests.sock_dir is not None' from iotest 300, because
that sort of thing is precisely what this patch wants to prevent.

Also, the filter now is smart enough to do copy-on-read with specified

do "-device e1000,noid" and get a device with "id=off".
Deprecate it and print a warning when it is encountered. In general,

While GDB can work with any XML description given to it there is
special handling for SVE registers on the GDB side which makes the
users life a little better. The changes aren't that major and all the
registers save the $vg reported the same. All that changes is:
- report org.gnu.gdb.aarch64.sve
- use gdb nomenclature for names and types
- minor re-ordering of the types to match reference
- re-enable ieee_half (as we know gdb supports it now)
- $vg is now a 64 bit int
- check $vN and $zN aliasing in test

then the chardev object won't be freed. This in turn means that the yank

yank_register_instance will abort, because the yank instance is

Prior to this patch, the fuzzer found inputs to map PCI device BARs and
enable the device. While it is nice that the fuzzer can do this, it
added significant overhead, since the fuzzer needs to map all the
BARs (regenerating the memory topology), at the start of each input.
With this patch, we do this once, before fuzzing, mitigating some of
this overhead.

There was a race condition in the first test where there was already the
"crw" output in the dmesg, but the "0.0.4711" entry has not been created
in the /sys fs yet. Fix it by waiting until it is there.
The second test has even more problems on gitlab-CI. Even after adding some
more synchronization points (that wait for some messages in the "dmesg"
output to make sure that the modules got loaded correctly), there are still
occasionally some hangs in this test when it is running in the gitlab-CI.
So far I was unable to reproduce these hangs locally on my computer, so
this issue might take a while to debug. Thus disable the 2nd test in the
gitlab-CI until the problems are better understood and fixed.

assertion failed:
https://gitlab.com/qemu-project/qemu/-/jobs/943183183
However short of cleaning up the test to be more binary focused at
least limit the attempt to dump the whole file as hexified zeros in
the logs.

cfi-icall is a form of Control-Flow Integrity for indirect function
calls implemented by llvm. It is enabled with a -fsanitize flag.
iotests are currently disabled when -fsanitize options is used, with the
exception of SafeStack.
This patch implements a generic filtering mechanism to allow iotests
with a set of known-to-be-safe -fsanitize option. Then marks SafeStack

commit 1e419ee68f ("chardev: generate an internal id when none
given") changed the reference ownership semantics of
qemu_chardev_new(NULL, ...): now all chardevs created using
qemu_chardev_new() are added to the /chardevs QOM container, and
the caller does not own a reference to the newly created object.
However, the code at char_file_test_internal() had not been
updated and was calling object_unref() on a chardev object it
didn't own. This makes the chardev be destroyed, but leaves a
dangling pointer in the /chardev container children list, and
seems to be the cause of the following char_serial_test() crash:
Unexpected error in object_property_try_add() at ../qom/object.c:1220: \
attempt to add duplicate property 'serial-id' to object (type 'container')
ERROR test-char - too few tests run (expected 38, got 9)
Update the code to use object_unparent() at the end of
char_file_test_internal(), to make sure the chardev will be
correctly removed from the QOM tree.

After adding some missing packages, it's possible to check 32-bit
builds and tests with the fedora-i386-cross container in the gitlab-CI,
too. Unfortunately, the code in subprojects/ ignores the --extra-cflags
(on purpose), so the vhost-user part has to be disabled for this.
While we're at it, update the container to Fedora 31. Unfortunately the
gcc from the later versions emits some very dubious format-truncation
warnings, so Fedora 32 and 33 are currently unsuitable for this job.

This initrd contains a virtio-net and a virtio-gpu kernel module,
so we can check that we can set a MAC address for the network device
and whether we can hot-plug and -unplug a virtio-crypto device.
But the most interesting part is maybe that we can also successfully
write some stuff into the emulated framebuffer of the virtio-gpu
device and make sure that we can read back that data from a screenshot.

qobject_to_json() and qobject_to_json_pretty() build a GString, then
covert it to QString. Just one of the callers actually needs a
QString: qemu_rbd_parse_filename(). A few others need a string they
can modify: qmp_send_response(), qga's send_response(), to_json_str(),
and qmp_fd_vsend_fds(). The remainder just need a string.
Change qobject_to_json() and qobject_to_json_pretty() to return the
GString.
qemu_rbd_parse_filename() now has to convert to QString. All others
save a QString temporary. to_json_str() actually becomes a bit
simpler, because GString provides more convenient modification
functions.

The string output visitor should serialize numbers so that the string
input visitor deserializes them back to the same number. It fails to
do so.
print_type_number() uses format %f. This is prone to nasty rounding
errors. For instance, numbers between 0 and 0.0000005 get flushed to
zero.
We currently use this visitor only for HMP info migrate, info network,
info qtree, and info memdev. No double values occur there as far as I
can tell.
Fix anyway by formatting with %.17g. 17 decimal digits always suffice
for IEEE double.

We should serialize numbers to JSON so that they deserialize back to
the same number. We fail to do so.
The culprit is qnum_to_string(): it uses format %f with trailing '0'
trimmed. Results in pretty output for "nice" numbers, but is prone to
nasty rounding errors. For instance, numbers between 0 and 0.0000005
get flushed to zero.
Where exactly the incorrect rounding can bite is tiresome to gauge.
Here's my take.
* In QMP output, type 'number':
- query-blockstats value avg_rd_queue_depth
- QMP query-migrate values mbps, cache-miss-rate, encoding-rate,
busy-rate, compression-rate.
Relatively harmless, I guess.
* In tracing QMP input. Harmless.
* In qemu-ga output, type 'number': guest-get-users value login-time.
Harmless.
* In output of HMP qom-get. Harmless.
Not affected, because double values don't actually occur there (I
think):
* QMP output, type 'any':
* qom-get value
* qom-list, qom-list-properties value default-value
* query-cpu-model-comparison, query-cpu-model-baseline,
query-cpu-model-expansion value props.
* qemu-img --output json output.
* "json:" pseudo-filenames generated by bdrv_refresh_filename().
* The rbd block driver's "=keyvalue-pairs" hack.
* In -object help on property default values. Aside: use of JSON
feels inappropriate here.
* Output of HMP qom-get.
* Argument conversion to QemuOpts for qdev_device_add() and HMP with
qemu_opts_from_qdict()
QMP and HMP device_add, virtio-net failover primary creation,
xen-usb "usb-host" creation, HMP netdev_add, object_add.
* The uses of qobject_input_visitor_new_flat_confused()
As far as I can tell, none of the visited types contain double
values.
* Dumping ImageInfoSpecific with dump_qobject()
Fix by formatting with %.17g. 17 decimal digits always suffice for
IEEE double.
The change to expected test output illustrates the effect: the
rounding errors are gone, but some seemingly "nice" numbers now get
converted to not so nice strings, e.g. 0.42 to "0.41999999999999998".
This is because 0.42 is not representable exactly in double. It's
more accurate in this example than strictly necessary, though.
If ugly accuracy bothers us, we can we can try using the least number
of digits that still converts back to the same double. In this
example, "0.42" would do.

qnum_to_string() has a FIXME comment about rounding errors due to
insufficient precision. Cover it: 2.718281828459045 gets converted to
"2.718282". The next commit will fix it.

Move one of large_number()'s three checks to uint_number(), and the
other two to float_number().
