3e7a95feb9 iotests: Add test for COR across nodes
COR across nodes (that is, you have some filter node between the
actually COR target and the node that performs the COR) cannot reliably
work together with the permission system when there is no explicit COR
node that can request the WRITE_UNCHANGED permission for its child.
This is because COR (currently) sneaks its requests by the usual
permission checks, so it can work without a WRITE* permission; but if
there is a filter node in between, that will re-issue the request, which
then passes through the usual check -- and if nobody has requested a
WRITE_UNCHANGED permission, that check will fail.

There is no real direct fix apart from hoping that there is someone who
has requested that permission; in case of just the qemu-io HMP command
(and no guest device), however, that is not the case.  The real real fix
is to implement the copy-on-read flag through an implicitly added COR
node.  Such a node can request the necessary permissions as shown in
this test.

81c6ddf49a iotests: Add failure matching to common.qemu
Currently, common.qemu only allows to match for results indicating
success.  The only way to fail is by provoking a timeout.  However,
sometimes we do have a defined failure output and can match for that,
which saves us from having to wait for the timeout in case of failure.
Because failure can sometimes just result in a _notrun in the test, it
is actually important to care about being able to fail quickly.

Also, sometimes we simply do not get any specific output in case of
success.  The only way to handle this currently would be to define an
error message as the string to look for, which means that actual success
results in a timeout.  This is really bad because it unnecessarily slows
down a succeeding test.

Therefore, this patch adds a new parameter $success_or_failure to
_timed_wait_for and _send_qemu_cmd.  Setting this to a non-empty string
makes both commands expect two match parameters: If the first matches,
the function succeeds.  If the second matches, the function fails.

52253998ec qcow2: Give the refcount cache the minimum possible size by default
The L2 and refcount caches have default sizes that can be overridden
using the l2-cache-size and refcount-cache-size (an additional
parameter named cache-size sets the combined size of both caches).

Unless forced by one of the aforementioned parameters, QEMU will set
the unspecified sizes so that the L2 cache is 4 times larger than the
refcount cache.

This is based on the premise that the refcount metadata needs to be
only a fourth of the L2 metadata to cover the same amount of disk
space. This is incorrect for two reasons:

 a) The amount of disk covered by an L2 table depends solely on the
    cluster size, but in the case of a refcount block it depends on
    the cluster size *and* the width of each refcount entry.
    The 4/1 ratio is only valid with 16-bit entries (the default).

 b) When we talk about disk space and L2 tables we are talking about
    guest space (L2 tables map guest clusters to host clusters),
    whereas refcount blocks are used for host clusters (including
    L1/L2 tables and the refcount blocks themselves). On a fully
    populated (and uncompressed) qcow2 file, image size > virtual size
    so there are more refcount entries than L2 entries.

Problem (a) could be fixed by adjusting the algorithm to take into
account the refcount entry width. Problem (b) could be fixed by
increasing a bit the refcount cache size to account for the clusters
used for qcow2 metadata.

However this patch takes a completely different approach and instead
of keeping a ratio between both cache sizes it assigns as much as
possible to the L2 cache and the remainder to the refcount cache.

The reason is that L2 tables are used for every single I/O request
from the guest and the effect of increasing the cache is significant
and clearly measurable. Refcount blocks are however only used for
cluster allocation and internal snapshots and in practice are accessed
sequentially in most cases, so the effect of increasing the cache is
negligible (even when doing random writes from the guest).

So, make the refcount cache as small as possible unless the user
explicitly asks for a larger one.

6cba5377f5 iotests: Split 214 off of 122
Commit abd3622cc0 added a case to 122
regarding how the qcow2 driver handles an incorrect compressed data
length value.  This does not really fit into 122, as that file is
supposed to contain qemu-img convert test cases, which this case is not.
So this patch splits it off into its own file; maybe we will even get
more qcow2-only compression tests in the future.

Also, that test case does not work with refcount_bits=1, so mark that
option as unsupported.

e652714f98 opts: don't silently truncate long parameter keys
The existing QemuOpts parsing code uses a fixed size 128 byte buffer
for storing the parameter keys. If a key exceeded this size it was
silently truncate and no error reported to the user. This behaviour was
reasonable & harmless because traditionally the key names are all
statically declared, and it was known that no code was declaring a key
longer than 127 bytes. This assumption, however, ceased to be valid once
the block layer added support for dot-separate compound keys. This
syntax allows for keys that can be arbitrarily long, limited only by the
number of block drivers you can stack up. With this usage, silently
truncating the key name can never lead to correct behaviour.

Hopefully such truncation would turn into an error, when the block code
then tried to extract options later, but there's no guarantee that will
happen. It is conceivable that an option specified by the user may be
truncated and then ignored. This could have serious consequences,
possibly even leading to security problems if the ignored option set a
security relevant parameter.

If the operating system didn't limit the user's argv when spawning QEMU,
the code should honour whatever length arguments were given without
imposing its own length restrictions. This patch thus changes the code
to use a heap allocated buffer for storing the keys during parsing,
lifting the arbitrary length restriction.

dc885fff97 iotests: Add test for cancelling a mirror job
We already have an extensive mirror test (041) which does cover
cancelling a mirror job, especially after it has emitted the READY
event.  However, it does not check what exact events are emitted after
block-job-cancel is executed.  More importantly, it does not use
throttling to ensure that it covers the case of block-job-cancel before
READY.

It would be possible to add this case to 041, but considering it is
already our largest test file, it makes sense to create a new file for
these cases.

ddc4115efd block/mirror: honor ratelimit again
Commit b76e4458b1 ("block/mirror: change
the semantic of 'force' of block-job-cancel") accidentally removed the
ratelimit in the mirror job.

Reintroduce the ratelimit but keep the block-job-cancel force=true
behavior that was added in commit
b76e4458b1.

Note that block_job_sleep_ns() returns immediately when the job is
cancelled.  Therefore it's safe to unconditionally call
block_job_sleep_ns() - a cancelled job does not sleep.

This commit fixes the non-deterministic qemu-iotests 185 output.  The
test relies on the ratelimit to make the job sleep until the 'quit'
command is processed.  Previously the job could complete before the
'quit' command was received since there was no ratelimit.

cb3e7f08ae qobject: Replace qobject_incref/QINCREF qobject_decref/QDECREF
Now that we can safely call QOBJECT() on QObject * as well as its
subtypes, we can have macros qobject_ref() / qobject_unref() that work
everywhere instead of having to use QINCREF() / QDECREF() for QObject
and qobject_incref() / qobject_decref() for its subtypes.

The replacement is mechanical, except I broke a long line, and added a
cast in monitor_qmp_cleanup_req_queue_locked().  Unlike
qobject_decref(), qobject_unref() doesn't accept void *.

Note that the new macros evaluate their argument exactly once, thus no
need to shout them.

3d3eacaecc qobject: use a QObjectBase_ struct
By moving the base fields to a QObjectBase_, QObject can be a type
which also has a 'base' field. This allows writing a generic QOBJECT()
macro that will work with any QObject type, including QObject
itself. The container_of() macro ensures that the object to cast has a
QObjectBase_ base field, giving some type safety guarantees. QObject
must have no members but QObjectBase_ base, or else QOBJECT() breaks.

QObjectBase_ is not a typedef and uses a trailing underscore to make
it obvious it is not for normal use and to avoid potential abuse.

46cfbf13b0 qobject: Use qobject_to() instead of type cast
The proper way to convert from (abstract) QObject to a (concrete)
subtype is qobject_to().  Look for offenders that type cast instead:

    $ git-grep '(Q[A-Z][a-z]* \*)'
    hmp.c:    qmp_device_add((QDict *)qdict, NULL, &err);

    tests/check-qdict.c:    dst = (QDict *)qdict_crumple(src, &error_abort);

The first two cast away const, the third isn't a type cast.  Fix the
fourth.

052888f043 hw/s390x: Allow to configure the consoles with the "-serial" parameter
The consoles ("sclpconsole" and "sclplmconsole") can only be configured
with "-device" and "-chardev" so far. Other machines use the convenience
option "-serial" to configure the default consoles, even for virtual
consoles like spapr-vty on the pseries machine. So let's support this
option on s390x, too. This way we can easily enable the serial console
here again with "-nodefaults", for example:

qemu-system-s390x -no-shutdown -nographic -nodefaults -serial mon:stdio

... which is way shorter than typing:

qemu-system-s390x -no-shutdown -nographic -nodefaults \
  -chardev stdio,id=c1,mux=on -device sclpconsole,chardev=c1 \
  -mon chardev=c1

The -serial parameter can also be used if you only want to see the QEMU
monitor on stdio without using -nodefaults, but not the console output.
That's something that is pretty impossible with the current code today:

qemu-system-s390x -no-shutdown -nographic -serial none

While we're at it, this patch also maps the second -serial option to the
"sclplmconsole", so that there is now an easy way to configure this second
console on s390x, too, for example:

qemu-system-s390x -no-shutdown -nographic -serial null -serial mon:stdio

Additionally, the new code is also smaller than the old one and we have
less s390x-specific code in vl.c :-)

I've also checked that migration still works as expected by migrating
a guest with console output back and forth between a qemu-system-s390x
that has this patch and an instance without this patch.

c1de5696d6 qemu-iotests: update 185 output
Commit 4486e89c21 ("vl: introduce
vm_shutdown()") added a bdrv_drain_all() call.  As a side-effect of the
drain operation the block job iterates one more time than before.  The
185 output no longer matches and the test is failing now.

It may be possible to avoid the superfluous block job iteration, but
that type of patch is not suitable late in the QEMU 2.12 release cycle.

This patch simply updates the 185 output file.  The new behavior is
correct, just not optimal, so make the test pass again.

Fixes: 4486e89c21 ("vl: introduce vm_shutdown()")

If there are more than one events, wait_until_completed() might return
the 2nd event even if the 1st event is JOB_COMPLETED, since the for loop
will continue to run even if completed is set to True.

It never happened before, but it can be triggered when OOB is enabled
due to the RESUME startup message. Fix that up.

057ad0b469 crypto: ensure we use a predictable TLS priority setting
The TLS test cert generation relies on a fixed set of algorithms that are
only usable under GNUTLS' default priority setting. When building QEMU
with a custom distro specific priority setting, this can cause the TLS
tests to fail. By forcing the tests to always use "NORMAL" priority we
can make them more robust.

abd3622cc0 iotests: Test abnormally large size in compressed cluster descriptor
L2 entries for compressed clusters have a field that indicates the
number of sectors used to store the data in the image.

That's however not the size of the compressed data itself, just the
number of sectors where that data is located. The actual data size is
usually not a multiple of the sector size, and therefore cannot be
represented with this field.

The way it works is that QEMU reads all the specified sectors and
starts decompressing the data until there's enough to recover the
original uncompressed cluster. If there are any bytes left that
haven't been decompressed they are simply ignored.

One consequence of this is that even if the size field is larger than
it needs to be QEMU can handle it just fine: it will read more data
from disk but it will ignore the extra bytes.

This test creates an image with two compressed clusters that use 5
sectors (2.5 KB) each, increases the size field to the maximum (8192
sectors, or 4 MB) and verifies that the data can be read without
problems.

This test is important because while the decompressed data takes
exactly one cluster, the maximum value allowed in the compressed size
field is twice the cluster size. So although QEMU won't produce images
with such large values we need to make sure that it can handle them.

Another effect of increasing the size field is that it can make
it include data from the following host cluster(s). In this case
'qemu-img check' will detect that the refcounts are not correct, and
we'll need to rebuild them.

Additionally, this patch also tests that decreasing the size corrupts
the image since the original data can no longer be recovered. In this
case QEMU returns an error when trying to read the compressed data,
but 'qemu-img check' doesn't see anything wrong if the refcounts are
consistent.

One possible task for the future is to make 'qemu-img check' verify
the sizes of the compressed clusters, by trying to decompress the data
and checking that the size stored in the L2 entry is correct.

fa198ad9bd tests: qmp-test: add test for new "x-oob"
Test the new OOB capability. It's mostly the reverted OOB test
(see commit 4fd78ad7), but differs in that:

- It uses the new qtest_init_without_qmp_handshake() parameter to
  create the monitor with "x-oob"
- Squashed the capability tests on greeting message
- Don't use qtest_global any more, instead use self-maintained
  QTestState, which is the trend

ddee57e017 tests: Add parameter to qtest_init_without_qmp_handshake
Allow callers to choose whether to allow OOB support during a test;
for now, all existing callers pass false, but the next patch will
add a new caller.  Also, rewrite the monitor setup to be generic
(using the -qmp shorthand is insufficient for honoring the parameter).

Based on an idea by Peter Xu, in <20180326063901.27425-8-peterx@redhat.com>

4bebca1e42 tests: let qapi-schema tests detect oob
The allow_oob parameter was passed in but not used in tests.  Now
reflect that in the tests, so we need to touch up other command testers
with that new change.

fdf235ba15 tests: Silence false positive warning on generated test name
Running 'make check' on rawhide with gcc 8.0.1 fails:

tests/test-visitor-serialization.c: In function 'main':
tests/test-visitor-serialization.c:1127:34: error: '/primitives/' directive writing 12 bytes into a region of size between 1 and 128 [-Werror=format-overflow=]

The warning is a false positive (we have two buffers of size 128,
so yes, if we FULLY used the first buffer, then sprint'ing it into
the second will overflow the second).  But in practice, our first
buffer will not be longer than "/visitor/serialization/String",
so sizing it smaller is enough to let gcc see that we don't
overflow the second.
