Kevin Wolf 2d7abfbeb7 qemu-iotests: Rewrite 212 for blockdev-create job
This rewrites the test case 212 to work with the new x-blockdev-create
job rather than the old synchronous version of the command.

All of the test cases stay the same as before, but in order to be able
to implement proper job handling, the test case is rewritten in Python.

Kevin Wolf e5ab4347f9 block/create: Make x-blockdev-create a job
This changes the x-blockdev-create QMP command so that it doesn't block
the monitor and the main loop any more, but starts a background job that
performs the image creation.

The basic job as implemented here is all that is necessary to make image
creation asynchronous and to provide a QMP interface that can be marked
stable, but it still lacks a few features that jobs usually provide: The
job will ignore pause commands and it doesn't publish more than very
basic progress yet (total-progress is 1 and current-progress advances
from 0 to 1 when the driver callbacks returns). These features can be
added later without breaking compatibility.

Kevin Wolf 1266c9b9f5 job: Add error message for failing jobs
So far we relied on job->ret and strerror() to produce an error message
for failed jobs. Not surprisingly, this tends to result in completely
useless messages.

This adds a Job.error field that can contain an error string for a
failing job, and a parameter to job_completed() that sets the field. As
a default, if NULL is passed, we continue to use strerror(job->ret).

All existing callers are changed to pass NULL. They can be improved in
separate patches.

Stefan Berger b21373d071 test: Add test cases that use the external swtpm with CRB interface
Add a test program for testing the CRB with the external swtpm.

The 1st test case extends a PCR and reads back the value and compares
it against an expected return packet.

The 2nd test case repeats the 1st test case and then migrates the
external swtpm's state along with the VM state to a destination
QEMU and swtpm and checks that the PCR has the expected value now.

The test cases require 'swtpm' to be installed on the system and
in the PATH and 'swtpm' must support the --tpm2 option. If this is
not the case, the test will be skipped.

Kevin Wolf df956ae201 job: Add job_is_ready()
Instead of having a 'bool ready' in BlockJob, add a function that
derives its value from the job status.

At the same time, this fixes the behaviour to match what the QAPI
documentation promises for query-block-job: 'true if the job may be
completed'. When the ready flag was introduced in commit ef6dbf1e46,
the flag never had to be reset to match the description because after
being ready, the jobs would immediately complete and disappear.

Job transactions and manual job finalisation were introduced only later.
With these changes, jobs may stay around even after having completed
(and they are not ready to be completed a second time), however their
patches forgot to reset the ready flag.

Move the defer_to_main_loop functionality from BlockJob to Job.

The code can be simplified because we can use job->aio_context in

Probably taking the data->aio_context lock in addition was already
unnecessary in the old code because we didn't actually make use of
anything protected by the old AioContext except getting the new
AioContext, in case it changed between scheduling the BH and running it.
But it's certainly unnecessary now that the BDS isn't accessed at all

Stefan Hajnoczi 4c7e813ce9 blockjob: do not cancel timer in resume
Currently the timer is cancelled and the block job is entered by
block_job_resume().  This behavior causes drain to run extra blockjob
iterations when the job was sleeping due to the ratelimit.

This patch leaves the job asleep when block_job_resume() is called.
Jobs can still be forcibly woken up using block_job_enter(), which is
used to cancel jobs.

After this patch drain no longer runs extra blockjob iterations.  This
is the expected behavior that qemu-iotests 185 used to rely on.  We
temporarily changed the 185 test output to make it pass for the QEMU
2.12 release but now it's time to address this issue.

Stefan Hajnoczi ddf2d98a94 qemu-iotests: reduce chance of races in 185
Commit 8565c3ab53 ("qemu-iotests: fix
185") identified a race condition in a sub-test.

Similar issues also affect the other sub-tests.  If disk I/O completes
quickly, it races with the QMP 'quit' command.  This causes spurious
test failures because QMP events are emitted in an unpredictable order.

This test relies on QEMU internals and there is no QMP API for getting
deterministic behavior needed to make this test 100% reliable.  At the
same time, the test is useful and it would be a shame to remove it.

Add sleep 0.5 to reduce the chance of races.  This is not a real fix but
appears to reduce spurious failures in practice.

Max Reitz 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.

Max Reitz 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.

Alberto Garcia 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.

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.

Daniel P. Berrangé 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.

Max Reitz 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.

Stefan Hajnoczi 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.

Marc-André Lureau 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.

Marc-André Lureau 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.

Thomas Huth 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.

Stefan Hajnoczi 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.

Alberto Garcia 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.

Peter Xu 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

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

Eric Blake 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: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.

Max Filippov d0ce7e9cfc target/xtensa: fix timers test
The value of CCOUNT special register is calculated as time elapsed
since CCOUNT == 0 multiplied by the core frequency. In icount mode time
increment between consecutive instructions that don't involve time
warps is constant, but unless the result of multiplication of this
constant by the core frequency is a whole number the CCOUNT increment
between these instructions may not be constant. E.g. with icount=7 each
instruction takes 128ns, with core clock of 10MHz CCOUNT values for
consecutive instructions are:

  502: (128 * 502 * 10000000) / 1000000000 = 642.56
  503: (128 * 503 * 10000000) / 1000000000 = 643.84
  504: (128 * 504 * 10000000) / 1000000000 = 645.12

I.e.the CCOUNT increments depend on the absolute time. This results in
varying CCOUNT differences for consecutive instructions in tests that
involve time warps and don't set CCOUNT explicitly.

Change frequency of the core used in tests so that clock cycle takes
exactly 64ns. Change icount power used in tests to 6, so that each
instruction takes exactly 1 clock cycle. With these changes CCOUNT
increments only depend on the number of executed instructions and that's
what timer tests expect, so they work correctly.

Before the chardev name fix, the following error may happen: "attempt

due to races.

Sadly, error_vprintf() uses g_test_message(), so you have to use
read the cryptic --debug-log to see it. Later, it would make sense to
use g_critical() instead, and catch errors with
g_test_expect_message() (in glib 2.34).

Alberto Garcia abf754fe40 qcow2: Reset free_cluster_index when allocating a new refcount block
When we try to allocate new clusters we first look for available ones
starting from s->free_cluster_index and once we find them we increase
their reference counts. Before we get to call update_refcount() to do
this last step s->free_cluster_index is already pointing to the next
cluster after the ones we are trying to allocate.

During update_refcount() it may happen however that we also need to
allocate a new refcount block in order to store the refcounts of these
new clusters (and to complicate things further that may also require
us to grow the refcount table). After all this we don't know if the
clusters that we originally tried to allocate are still available, so
we return -EAGAIN to ask the caller to restart the search for free
clusters.

This is what can happen in a common scenario:

  1) We want to allocate a new cluster and we see that cluster N is
     free.

  2) We try to increase N's refcount but all refcount blocks are full,
     so we allocate a new one at N+1 (where s->free_cluster_index was
     pointing at).

  3) Once we're done we return -EAGAIN to look again for a free
     cluster, but now s->free_cluster_index points at N+2, so that's
     the one we allocate. Cluster N remains unallocated and we have a
     hole in the qcow2 file.

This can be reproduced easily:

     qemu-img create -f qcow2 -o cluster_size=512 hd.qcow2 1M
     qemu-io -c 'write 0 124k' hd.qcow2

After this the image has 132608 bytes (256 clusters), and the refcount
block is full. If we write 512 more bytes it should allocate two new
clusters: the data cluster itself and a new refcount block.

     qemu-io -c 'write 124k 512' hd.qcow2

However the image has now three new clusters (259 in total), and the
first one of them is empty (and unallocated):

     dd if=hd.qcow2 bs=512c skip=256 count=1 | hexdump -C

If we write larger amounts of data in the last step instead of the 512
bytes used in this example we can create larger holes in the qcow2
file.

What this patch does is reset s->free_cluster_index to its previous
value when alloc_refcount_block() returns -EAGAIN. This way the caller
will try to allocate again the original clusters if they are still
free.

The output of iotest 026 also needs to be updated because now that
images have no holes some tests fail at a different point and the
number of leaked clusters is different.

Eric Blake 39615354fc qapi: Force UTF8 encoding when parsing qapi files
Commit d4e5ec877 already fixed things to work around Python 3's
lame bug of having LC_ALL=C not be 8-bit clean, when parsing the
main QMP qapi files; but failed to do likewise in the tests
directory.  As a result, running 'LC_ALL=C make check' fails on
escape-too-big and unicode-str when using python 3 with a nasty
stack trace instead of the intended graceful error message that
QAPI doesn't yet support 8-bit data (the two tests contain
Unicode é, when parsed in UTF-8; they represent something
different when parsed in a proper single-byte C locale, but that
doesn't matter to the error message printed out, provided that
brain-dead Python hasn't first choked on the input instead of
being 8-bit clean).

Ideally, we'd teach the qapi generator scripts to automatically
slurp things in using UTF-8 regardless of locale, and to honor
content that is not limited to 7 bit data rather than gracefully
erroring out; but until then, since our graceful error depends
on python parsing 8-bit data (even if nothing we generate uses
8-bit data), our quick fix is to use the right locale when
running these tests.

This reverts commit 3fd2457d18.

Enabling OOB caused several iotests failures; due to the imminent
2.12 release, the safest action is to disable OOB for now.  If
other patches fix the issues that iotests exposed, it may be turned
back on in time for the release, otherwise it will be 2.13 material;
either way, the framework changes not reverted now do not hurt if
they remain as part of the 2.12 release.

Additionally, revert the tests in the patch 02130314d8 ("qmp: introduce

Haozhong Zhang adae91ce32 tests/bios-tables-test: add test cases for DIMM proximity
QEMU now builds one SRAT memory affinity structure for each PC-DIMM
and NVDIMM device presented at boot time with the proximity domain
specified in the device option 'node', rather than only one SRAT
memory affinity structure covering the entire hotpluggable address
space with the proximity domain of the last node.

Add test cases on PC and Q35 machines with 4 proximity domains, and
one PC-DIMM and one NVDIMM attached to the 2nd and 3rd proximity
domains respectively. Check whether the QEMU-built SRAT tables match
with the expected ones.

The following ACPI tables need to be added for this test:
  tests/acpi-test-data/pc/APIC.dimmpxm
  tests/acpi-test-data/pc/DSDT.dimmpxm
  tests/acpi-test-data/pc/NFIT.dimmpxm

New APIC and DSDT are needed because of the multiple processors
configuration. New NFIT and SSDT are needed because of NVDIMM.

Peter Xu 876c67512e qapi: introduce new cmd option "allow-oob"
Here "oob" stands for "Out-Of-Band".  When "allow-oob" is set, it means
the command allows out-of-band execution.

The "oob" idea is proposed by Markus Armbruster in following thread:

  https://lists.gnu.org/archive/html/qemu-devel/2017-09/msg02057.html

This new "allow-oob" boolean will be exposed by "query-qmp-schema" as
well for command entries, so that QMP clients can know which commands
can be used in out-of-band calls. For example the command "migrate"
originally looks like:

  {"name": "migrate", "ret-type": "17", "meta-type": "command",
   "arg-type": "86"}

And it'll be changed into:

  {"name": "migrate", "ret-type": "17", "allow-oob": false,
   "meta-type": "command", "arg-type": "86"}

This patch only provides the QMP interface level changes.  It does not
contain the real out-of-band execution implementation yet.

Peter Xu 02130314d8 qmp: introduce QMPCapability
There were no QMP capabilities defined.  Define the first capability,
"oob", to allow out-of-band messages.

After this patch, we will allow QMP clients to enable QMP capabilities
when sending the first "qmp_capabilities" command.  Originally we are
starting QMP session with no arguments like:

  { "execute": "qmp_capabilities" }

Now we can enable some QMP capabilities using (take OOB as example,
which is the only capability that we support):

  { "execute": "qmp_capabilities",
    "arguments": { "enable": [ "oob" ] } }

When the "arguments" key is not provided, no capability is enabled.

For capability "oob", the monitor needs to be run on a dedicated IO
thread, otherwise the command will fail.  For example, trying to enable
OOB on a MUXed typed QMP monitor will fail.

One thing to mention is that QMP capabilities are per-monitor, and also
when the connection is closed due to some reason, the capabilities will
be reset.

Also, touch up qmp-test.c to test the new bits.

Eric Blake 63ca8406be iotests: Avoid realpath, for CentOS 6
CentOS 6 lacks a realpath binary on the base install, which makes
all iotests runs fail since the 2.11 release:

001         - output mismatch (see 001.out.bad)
./check: line 815: realpath: command not found
diff: missing operand after `/home/dummy/qemu/tests/qemu-iotests/001.out'
diff: Try `diff --help' for more information.

Many of the uses of 'realpath' in the check script were being
used on the output of 'type -p' - but that is already an
absolute file name.  While a canonical name can often be
shorter (realpath gets rid of /../), it can also be longer (due
to symlink expansion); and we really don't care if the name is
canonical, merely that it was an executable file with an
absolute path.  These were broken in commit cceaf1db.

The remaining use of realpath was to convert a possibly relative
filename into an absolute one before calling diff to make it
easier to copy-and-paste the filename for moving the .bad file
into place as the new reference file even when running iotests
out-of-tree (see commit 93e53fb6), but $PWD can achieve the same
purpose.

Liang Li b76e4458b1 block/mirror: change the semantic of 'force' of block-job-cancel
When doing drive mirror to a low speed shared storage, if there was heavy
BLK IO write workload in VM after the 'ready' event, drive mirror block job
can't be canceled immediately, it would keep running until the heavy BLK IO
workload stopped in the VM.

Libvirt depends on the current block-job-cancel semantics, which is that
when used without a flag after the 'ready' event, the command blocks
until data is in sync.  However, these semantics are awkward in other
situations, for example, people may use drive mirror for realtime
backups while still wanting to use block live migration.  Libvirt cannot
start a block live migration while another drive mirror is in progress,
but the user would rather abandon the backup attempt as broken and
proceed with the live migration than be stuck waiting for the current
drive mirror backup to finish.

The drive-mirror command already includes a 'force' flag, which libvirt
does not use, although it documented the flag as only being useful to
quit a job which is paused.  However, since quitting a paused job has
the same effect as abandoning a backup in a non-paused job (namely, the
destination file is not in sync, and the command completes immediately),
we can just improve the documentation to make the force flag obviously
useful.

Kevin Wolf e1473133f7 qemu-iotests: Enable write tests for parallels
Originally we added parallels as a read-only format to qemu-iotests
where we did just some tests with a binary image. Since then, write and
image creation support has been added to the driver, so we can now
enable it in _supported_fmt generic.

The driver doesn't support migration yet, though, so we need to add it
to the list of exceptions in 181.

John Snow 0ec4dfb8d6 blockjobs: add block_job_verb permission table
Which commands ("verbs") are appropriate for jobs in which state is
also somewhat burdensome to keep track of.

As of this commit, it looks rather useless, but begins to look more
interesting the more states we add to the STM table.

A recurring theme is that no verb will apply to an 'undefined' job.

Further, it's not presently possible to restrict the "pause" or "resume"
verbs any more than they are in this commit because of the asynchronous
nature of how jobs enter the PAUSED state; justifications for some
seemingly erroneous applications are given below.

=====
Verbs
=====

Cancel:    Any state except undefined.
Pause:     Any state except undefined;
           'created': Requests that the job pauses as it starts.
           'running': Normal usage. (PAUSED)
           'paused':  The job may be paused for internal reasons,
                      but the user may wish to force an indefinite
                      user-pause, so this is allowed.
           'ready':   Normal usage. (STANDBY)
           'standby': Same logic as above.
Resume:    Any state except undefined;
           'created': Will lift a user's pause-on-start request.
           'running': Will lift a pause request before it takes effect.
           'paused':  Normal usage.
           'ready':   Will lift a pause request before it takes effect.
           'standby': Normal usage.
Set-speed: Any state except undefined, though ready may not be meaningful.
Complete:  Only a 'ready' job may accept a complete request.

=======
Changes
=======

(1)

To facilitate "nice" error checking, all five major block-job verb
interfaces in blockjob.c now support an errp parameter:

- block_job_user_cancel is added as a new interface.
- block_job_user_pause gains an errp paramter
- block_job_user_resume gains an errp parameter
- block_job_set_speed already had an errp parameter.
- block_job_complete already had an errp parameter.

(2)

block-job-pause and block-job-resume will no longer no-op when trying
to pause an already paused job, or trying to resume a job that isn't
paused. These functions will now report that they did not perform the
action requested because it was not possible.

iotests have been adjusted to address this new behavior.

(3)

block-job-complete doesn't worry about checking !block_job_started,
because the permission table guards against this.

(4)

test-bdrv-drain's job implementation needs to announce that it is
'ready' now, in order to be completed.

John Snow f03d9d243f iotests: add pause_wait
Split out the pause command into the actual pause and the wait.
Not every usage presently needs to resubmit a pause request.

The intent with the next commit will be to explicitly disallow
redundant or meaningless pause/resume requests, so the tests
need to become more judicious to reflect that.

John Snow 58b295ba52 blockjobs: add status enum
We're about to add several new states, and booleans are becoming
unwieldly and difficult to reason about. It would help to have a
more explicit bookkeeping of the state of blockjobs. To this end,
add a new "status" field and add our existing states in a redundant
manner alongside the bools they are replacing:

UNDEFINED: Placeholder, default state. Not currently visible to QMP
           unless changes occur in the future to allow creating jobs
           without starting them via QMP.
CREATED:   replaces !!job->co && paused && !busy
RUNNING:   replaces effectively (!paused && busy)
PAUSED:    Nearly redundant with info->paused, which shows pause_count.
           This reports the actual status of the job, which almost always
           matches the paused request status. It differs in that it is
           strictly only true when the job has actually gone dormant.
READY:     replaces job->ready.
STANDBY:   Paused, but job->ready is true.

New state additions in coming commits will not be quite so redundant:

WAITING:   Waiting on transaction. This job has finished all the work
           it can until the transaction converges, fails, or is canceled.
PENDING:   Pending authorization from user. This job has finished all the
           work it can until the job or transaction is finalized via
           block_job_finalize. This implies the transaction has converged
           and left the WAITING phase.
ABORTING:  Job has encountered an error condition and is in the process
           of aborting.
CONCLUDED: Job has ceased all operations and has a return code available
           for query and may be dismissed via block_job_dismiss.
NULL:      Job has been dismissed and (should) be destroyed. Should never
           be visible to QMP.

Some of these states appear somewhat superfluous, but it helps define the
expected flow of a job; so some of the states wind up being synchronous
empty transitions. Importantly, jobs can be in only one of these states
at any given time, which helps code and external users alike reason about
the current condition of a job unambiguously.

John Snow 75859b9420 blockjobs: model single jobs as transactions
model all independent jobs as single job transactions.

It's one less case we have to worry about when we add more states to the
transition machine. This way, we can just treat all job lifetimes exactly
the same. This helps tighten assertions of the STM graph and removes some
conditionals that would have been needed in the coming commits adding a
more explicit job lifetime management API.

Test

    - fix bitmap sha256
    - clear bitmap
    - do writes from set A
    - start migration
- than, in b
    - wait vm start (postcopy should start)
    - do writes from set B
    - check bitmap sha256

The test should verify postcopy migration and then merging with delta
(changes in target, during postcopy process).

Reduce supported cache modes to only 'none', because with cache on time
from source.STOP to target.RESUME is unpredictable and we can fail with
timout while waiting for target.RESUME.

Daniel P. Berrange 0935700f85 char: allow passing pre-opened socket file descriptor at startup
When starting QEMU management apps will usually setup a monitor socket, and
then open it immediately after startup. If not using QEMU's own -daemonize
arg, this process can be troublesome to handle correctly. The mgmt app will
need to repeatedly call connect() until it succeeds, because it does not
know when QEMU has created the listener socket. If can't retry connect()
forever though, because an error might have caused QEMU to exit before it
even creates the monitor.

The obvious way to fix this kind of problem is to just pass in a pre-opened
socket file descriptor for the QEMU monitor to listen on. The management
app can now immediately call connect() just once. If connect() fails it
knows that QEMU has exited with an error.

The SocketAddress(Legacy) structs allow for FD passing via the monitor, and
now via inherited file descriptors from the process that spawned QEMU. The
final missing piece is adding a 'fd' parameter in the socket chardev
options.

This allows both HMP usage, pass any FD number with SCM_RIGHTS, then
running HMP commands:

   getfd myfd
   chardev-add socket,fd=myfd

Note that numeric FDs cannot be referenced directly in HMP, only named FDs.

And also CLI usage, by leak FD 3 from parent by clearing O_CLOEXEC, then
spawning QEMU with

  -chardev socket,fd=3,id=mon
  -mon chardev=mon,mode=control

Note that named FDs cannot be referenced in CLI args, only numeric FDs.

We do not wire this up in the legacy chardev syntax, so you cannot use FD
passing with '-qmp', you must use the modern '-mon' + '-chardev' pair.

When passing pre-opened FDs there is a restriction on use of TLS encryption.
It can be used on a server socket chardev, but cannot be used for a client
socket chardev. This is because when validating a server's certificate, the
client needs to have a hostname available to match against the certificate
identity.

An illustrative example of usage is:

  #!/usr/bin/perl

  use IO::Socket::UNIX;
  use Fcntl;

  unlink "/tmp/qmp";
  my $srv = IO::Socket::UNIX->new(
    Type => SOCK_STREAM(),
    Local => "/tmp/qmp",
    Listen => 1,
  );

  my $flags = fcntl $srv, F_GETFD, 0;
  fcntl $srv, F_SETFD, $flags & ~FD_CLOEXEC;

  my $fd = $srv->fileno();

  exec "qemu-system-x86_64", \
      "-chardev", "socket,fd=$fd,server,nowait,id=mon", \
      "-mon", "chardev=mon,mode=control";

Daniel P. Berrange 1723d6b1cf sockets: allow SocketAddress 'fd' to reference numeric file descriptors
The SocketAddress 'fd' kind accepts the name of a file descriptor passed
to the monitor with the 'getfd' command. This makes it impossible to use
the 'fd' kind in cases where a monitor is not available. This can apply in
handling command line argv at startup, or simply if internal code wants to
use SocketAddress and pass a numeric FD it has acquired from elsewhere.

Fortunately the 'getfd' command mandated that the FD names must not start
with a leading digit. We can thus safely extend semantics of the
SocketAddress 'fd' kind, to allow a purely numeric name to reference an
file descriptor that QEMU already has open. There will be restrictions on
when each kind can be used.

In codepaths where we are handling a monitor command (ie cur_mon != NULL),
we will only support use of named file descriptors as before. Use of FD
numbers is still not permitted for monitor commands.

In codepaths where we are not handling a monitor command (ie cur_mon ==
NULL), we will not support named file descriptors. Instead we can reference
FD numers explicitly. This allows the app spawning QEMU to intentionally
"leak" a pre-opened socket to QEMU and reference that in a SocketAddress
definition, or for code inside QEMU to pass pre-opened FDs around.

Daniel P. Berrange 30bdb3c56d sockets: check that the named file descriptor is a socket
The SocketAddress struct has an "fd" type, which references the name of a
file descriptor passed over the monitor using the "getfd" command. We
currently blindly assume the FD is a socket, which can lead to hard to
diagnose errors later. This adds an explicit check that the FD is actually
a socket to improve the error diagnosis.

Dr. David Alan Gilbert f96d6651e4 tests: Silence migration-test 'bad' test
In 2c9bb29703 I added a migration test that purposely fails;
unfortunately it prints a copy of the failure message to stderr
which makes the output a bit messy.

Hide stderr for that test.

Stefan Hajnoczi 21794244d4 qemu-iotests: fix 203 migration completion race
There is a race between the test's 'query-migrate' QMP command after the
QMP 'STOP' event and completing the migration:

The test case invokes 'query-migrate' upon receiving 'STOP'.  At this
point the migration thread may still be in the process of completing.
Therefore 'query-migrate' can return 'status': 'active' for a brief
window of time instead of 'status': 'completed'.  This results in
qemu-iotests 203 hanging.

Solve the race by enabling the 'events' migration capability, which
causes QEMU to emit migration-specific QMP events that do not suffer
from this race condition.  Wait for the QMP 'MIGRATION' event with
'status': 'completed'.

Alberto Garcia 39eaefcedb iotests: Tweak 030 in order to trigger a race condition with parallel jobs
This patch tweaks TestParallelOps in iotest 030 so it allocates data
in smaller regions (256KB/512KB instead of 512KB/1MB) and the
block-stream job in test_stream_commit() only needs to copy data that
is at the very end of the image.

This way when the block-stream job is awakened it will finish right
away without any chance of being stopped by block_job_sleep_ns(). This
triggers the bug that was fixed by 3d5d319e12 and
1a63a90750 and is therefore a more useful test
case for parallel block jobs.

After this patch the aforementiond bug can also be reproduced with the
test_stream_parallel() test case.

Since with this change the stream job in test_stream_commit() finishes
early, this patch introduces a similar test case where both jobs are
slowed down so they can actually run in parallel.

Kevin Wolf b76b4f6045 qcow2: Use visitor for options in qcow2_create()
Instead of manually creating the BlockdevCreateOptions object, use a
visitor to parse the given options into the QAPI object.

This involves translation from the old command line syntax to the syntax
mandated by the QAPI schema. Option names are still checked against
qcow2_create_opts, so only the old option names are allowed on the
command line, even if they are translated in qcow2_create().

In contrast, new option values are optionally recognised besides the old
values: 'compat' accepts 'v2'/'v3' as an alias for '0.10'/'1.1', and
'encrypt.format' accepts 'qcow' as an alias for 'aes' now.

This function deletes a snapshot from disk, removing its entry from
the snapshot table, freeing its L1 table and decreasing the refcounts
of all clusters.

The L1 table offset and size are however not validated. If we use
invalid values in this function we'll probably corrupt the image even
more, so we should return an error instead.

Alberto Garcia 0cf0e5980b qcow2: Generalize validate_table_offset() into qcow2_validate_table()
This function checks that the offset and size of a table are valid.

While the offset checks are fine, the size check is too generic, since
it only verifies that the total size in bytes fits in a 64-bit
integer. In practice all tables used in qcow2 have much smaller size
limits, so the size needs to be checked again for each table using its
actual limit.

This patch generalizes this function by allowing the caller to specify
the maximum size for that table. In addition to that it allows passing
an Error variable.

The function is also renamed and made public since we're going to use
it in other parts of the code.
