454590916c pseries: fix migration-test and pxe-test
Commit 29cb418749 ("spapr: Set VSMT to smp_threads by default")
has introduced a new default value for VSMT that is not supported
by old kernels (before 4.13 kernel) and this breaks "make check"
on these kernels.

To fix that, explicitly set in the involved tests the value that was
used as the default value before the change.

bcc388df07 tests/vm: make --interactive (and therefore DEBUG=1) unconditional
While the concept of only dropping to ssh if a test fails is nice it
is more useful for this to be unconditional. You usually just want to
get the build up and running and then noodle around debugging or
attempting to replicate.

6c77aa909e tests: acpi: always retain dumped ACPI tables in case of error
If IASL wasn't able to parse expected file, test will just
print warning
  "Warning! iasl couldn't parse the expected aml\n"
and remove temporary table dumped from guest.

Typically expected tables are always valid, with an exception
when patchset introduces new tables.
Make sure dumped tables are retained even if expected files
are not valid, so one could have a chance to manualy check new
tables.

a98b1a1fef iotests: Include QMP input in .out files
We generally include relevant HMP input in .out files, by virtue of
the fact that HMP echoes its input.  But QMP does not, so we have to
explicitly inject it in the output stream (appropriately filtered to
keep the tests passing), in order to make it easier to read .out files
to see what behavior is being tested (especially true where the output
file is a sequence of {'return': {}}).

f3923a72f1 iotests: Switch nbd tests to use Unix rather than TCP
Up to now, all it took to cause a lot of iotest failures was to have a
background process such as 'nbdkit -p 10810 null' running, because we
hard-coded the TCP port.  Switching to a Unix socket eliminates this
contention.  We still have TCP coverage in test 233, and that test is
more careful to not pick a hard-coded port.

Add a comment explaining where the format layer applies when using
NBD as protocol (until NBD gains support for a resize extension, we
only pipe raw bytes over the wire).

509e91c127 iotests: Fix 173
This test has been broken since 3.0.  It used TEST_IMG to influence
the name of a file created during _make_test_img, but commit 655ae6bb
changed things so that the wrong file name is being created, which
then caused _launch_qemu to fail.  In the meantime, the set of events
issued for the actions of the test has increased.

Why haven't we noticed the failure? Because the test rarely gets run:
'./check -qcow2 173' is insufficient (that defaults to using file protocol)
'./check -nfs 173' is insufficient (that defaults to using raw format)
so the test is only run with:
./check -qcow2 -nfs 173

Note that we already have a number of other problems with -nfs:
./check -nfs (fails 18/30)
./check -qcow2 -nfs (fails 45/76 after this patch, if exports does
not permit 'insecure')
and it's not on my priority list to fix those.  Rather, I found this
because of my next patch's work on tests using _send_qemu_cmd.

This test has been unstable on NetBSD for awhile. It seems the
mechanism used to listen to a random port is a Linux-ism (although a
received wisdom Linux-ism rather than a well documented one). As
working around would add more hard to test complexity to the test I've
gone for the easier option of making it CONFIG_LINUX only.

87014c6b36 target/arm/kvm: host cpu: Add support for sve<N> properties
Allow cpu 'host' to enable SVE when it's available, unless the
user chooses to disable it with the added 'sve=off' cpu property.
Also give the user the ability to select vector lengths with the
sve<N> properties. We don't adopt 'max' cpu's other sve property,
sve-max-vq, because that property is difficult to use with KVM.
That property assumes all vector lengths in the range from 1 up
to and including the specified maximum length are supported, but
there may be optional lengths not supported by the host in that
range. With KVM one must be more specific when enabling vector
lengths.

6fa8a37949 target/arm/cpu64: max cpu: Support sve properties with KVM
Extend the SVE vq map initialization and validation with KVM's
supported vector lengths when KVM is enabled. In order to determine
and select supported lengths we add two new KVM functions for getting
and setting the KVM_REG_ARM64_SVE_VLS pseudo-register.

This patch has been co-authored with Richard Henderson, who reworked
the target/arm/cpu64.c changes in order to push all the validation and
auto-enabling/disabling steps into the finalizer, resulting in a nice
LOC reduction.

Enable SVE in the KVM guest when the 'max' cpu type is configured
and KVM supports it. KVM SVE requires use of the new finalize
vcpu ioctl, so we add that now too. For starters SVE can only be
turned on or off, getting all vector lengths the host CPU supports
when on. We'll add the other SVE CPU properties in later patches.

0df9142d27 target/arm/cpu64: max cpu: Introduce sve<N> properties
Introduce cpu properties to give fine control over SVE vector lengths.
We introduce a property for each valid length up to the current
maximum supported, which is 2048-bits. The properties are named, e.g.
sve128, sve256, sve384, sve512, ..., where the number is the number of
bits. See the updates to docs/arm-cpu-features.rst for a description
of the semantics and for example uses.

Note, as sve-max-vq is still present and we'd like to be able to
support qmp_query_cpu_model_expansion with guests launched with e.g.
-cpu max,sve-max-vq=8 on their command lines, then we do allow
sve-max-vq and sve<N> properties to be provided at the same time, but
this is not recommended, and is why sve-max-vq is not mentioned in the
document.  If sve-max-vq is provided then it enables all lengths smaller
than and including the max and disables all lengths larger. It also has
the side-effect that no larger lengths may be enabled and that the max
itself cannot be disabled. Smaller non-power-of-two lengths may,
however, be disabled, e.g. -cpu max,sve-max-vq=4,sve384=off provides a
guest the vector lengths 128, 256, and 512 bits.

This patch has been co-authored with Richard Henderson, who reworked
the target/arm/cpu64.c changes in order to push all the validation and
auto-enabling/disabling steps into the finalizer, resulting in a nice
LOC reduction.

dc237c45ae hd-geo-test: Add tests for lchs override
Add QTest tests to check the logical geometry override option.

The tests in hd-geo-test are out of date - they only test IDE and do not
test interesting MBRs.

Creating qcow2 disks with specific size and MBR layout is currently
unused - we only use a default empty MBR.

f3cad9c6db iotests: Remove 130 from the "auto" group
Peter hit a "Could not open 'TEST_DIR/t.IMGFMT': Failed to get shared
'write' lock - Is another process using the image [TEST_DIR/t.IMGFMT]?"
error with 130 already twice. Looks like this test is a little bit
shaky, and currently nobody has a real clue what could be causing this
issue, so for the time being, let's disable it from the "auto" group so
that it does not gate the pull requests.

2ecde8b2fb Acceptance test: update kernel for m68k/q800 test
There's an updated version of the Debian package containing the m68k
Kernel.

Now, if the package gets updated again, the test won't fail, but will
be canceled.  A more permanent solution is certainly needed.

d2499aca4b Acceptance test: cancel test if m68k kernel packages goes missing
The Linux kernel that is extracted from a Debian package for the q800
machine test is hosted on a "pool" location.  AFAICT, it gets updated
without too much ceremony, and I don't see any archival location that
is stable enough.

For now, to avoid test errors, let's cancel the test if fetching the
package fails.

4599cb953c crypto: improve performance of ciphers in XTS mode
Currently QEMU uses its own XTS cipher mode, however, this has
 relatively poor performance.
 
 Gcrypt now includes its own XTS cipher which is at least x2 faster than
 what we get with QEMU's on Fedora/RHEL hosts. With gcrypt git master, a
 further x5-6 speed up is seen.
 
 This is essential for QEMU's LUKS performance to be viable.

bf83f04e13 qapi: Fix doc comment checking for commands and events
When a command's 'data' is an object, its doc comment describes the
arguments defined there.  When 'data' names a type, the doc comment
does not describe arguments.  Instead, the doc generator inserts a
pointer to the named type.

An event's doc comment works the same.

We don't actually check doc comments for commands and events.
Instead, QAPISchema._def_command() forwards the doc comment to the
implicit argument type, where it gets checked.  Works because the
check only cares for the implicit argument type's members.

Not only is this needlessly hard to understand, it actually falls
apart in two cases:

* When 'data' is empty, there is nothing to forward to, and the doc
  comment remains unchecked.  Demonstrated by test doc-bad-event-arg.

* When 'data' names a type, we can't forward, as the type has its own
  doc comment.  The command or event's doc comment remains unchecked.
  Demonstrated by test doc-bad-boxed-command-arg.

The forwarding goes back to commit 069fb5b250 "qapi: Prepare for
requiring more complete documentation", put to use in commit
816a57cd6e "qapi: Fix detection of bogus member documentation".  That
fix was incomplete.

To fix this, make QAPISchemaCommand and QAPISchemaEvent check doc
comments, and drop the forwarding of doc comments to implicit argument
types.

Enumeration type documentation comments are not checked, as
demonstrated by test doc-bad-enum-member.  This is because we neglect
to call self.doc.check() for enumeration types.  Messed up in

efdb45bfd7 tests/boot_linux_console: Run BusyBox on 5KEc 64-bit cpu
This tests boots a Linux kernel on a Malta machine up to a
busybox shell on the serial console. Few commands are executed
before halting the machine (via reboot).

We use the Fedora 24 kernel extracted from the image at:
https://fedoraproject.org/wiki/Architectures/MIPS
and the initrd cpio image from the kerneltests project:
https://kerneltests.org/

If MIPS is a target being built, "make check-acceptance" will
automatically include this test by the use of the "arch:mips" tags.

Alternatively, this test can be run using:

Change 32558ce7a4 introduced specific directories for the socket dir
when using python/qemu/machine.py:QEMUMachine.  iotests probably
didn't catch the condition that two simultaneous QEMUMachine
instances, without manually set temporary or socket dirs would clash.

Having two QEMUMachine instances is a condition expected for many
acceptance tests, and it's already used by the migration tests.

e0576942e0 crypto: add support for gcrypt's native XTS impl
Libgcrypt 1.8.0 added support for the XTS mode. Use this because long
term we wish to delete QEMU's XTS impl to avoid carrying private crypto
algorithm impls.

As an added benefit, using this improves performance from 531 MB/sec to
670 MB/sec, since we are avoiding several layers of function call
indirection.

This is even more noticable with the gcrypt builds in Fedora or RHEL-8
which have a non-upstream patch for FIPS mode which does mutex locking.
This is catastrophic for encryption performance with small block sizes,
meaning this patch improves encryption from 240 MB/sec to 670 MB/sec.

a208ba09bd tests/plugin: add a hotblocks plugin
This is a simple plugin to track which translation blocks are call
most often. As we don't have a view of the internals of TCG we can
only work by the address of the start of the block so we also need to
tracks how often the address is translated.

As there will be multiple blocks starting at the same address. We can
try and work around this by futzing the value to feed to the hash with
the insn count.

3089e74e67 tests/tcg: enable plugin testing
If CONFIG_PLUGINS is enabled then lets enable testing for all our TCG
targets. This is a simple smoke test that ensure we don't crash or
otherwise barf out by running each plugin against each test.

There is a minor knock on effect for additional runners which need
specialised QEMU_OPTS which will also need to declare a plugin version
of the runner. If this gets onerous we might need to add another
helper.

Checking the results of the plugins is left for a later exercise.

b4296d7f88 tests: benchmark crypto with fixed data size, not time period
Currently the crypto benchmarks are processing data in varying chunk
sizes, over a fixed time period. This turns out to be a terrible idea
because with small chunk sizes the overhead of checking the elapsed
time on each loop iteration masks the true performance.

Benchmarking over a fixed data size avoids the loop running any system
calls which can interfere with the performance measurements.

Before this change

Enc chunk 512 bytes 2283.47 MB/sec Dec chunk 512 bytes 2236.23 MB/sec OK
Enc chunk 4096 bytes 2744.97 MB/sec Dec chunk 4096 bytes 2614.71 MB/sec OK
Enc chunk 16384 bytes 2777.53 MB/sec Dec chunk 16384 bytes 2678.44 MB/sec OK
Enc chunk 65536 bytes 2809.34 MB/sec Dec chunk 65536 bytes 2699.47 MB/sec OK

After this change

Enc chunk 512 bytes 2058.22 MB/sec Dec chunk 512 bytes 2030.11 MB/sec OK
Enc chunk 4096 bytes 2699.27 MB/sec Dec chunk 4096 bytes 2573.78 MB/sec OK
Enc chunk 16384 bytes 2748.52 MB/sec Dec chunk 16384 bytes 2653.76 MB/sec OK
Enc chunk 65536 bytes 2814.08 MB/sec Dec chunk 65536 bytes 2712.74 MB/sec OK

The actual crypto performance hasn't changed, which shows how
significant the mis-measurement has been for small data sizes.

need it for all formats. Let's restrict it to qcow2 only.

c80d8b06cf block: Add @exact parameter to bdrv_co_truncate()
We have two drivers (iscsi and file-posix) that (in some cases) return
success from their .bdrv_co_truncate() implementation if the block
device is larger than the requested offset, but cannot be shrunk.  Some
callers do not want that behavior, so this patch adds a new parameter
that they can use to turn off that behavior.

This patch just adds the parameter and lets the block/io.c and
block/block-backend.c functions pass it around.  All other callers
always pass false and none of the implementations evaluate it, so that
this patch does not change existing behavior.  Future patches take care
of that.

c7df3f19d2 iotests: Introduce $SOCK_DIR
Unix sockets generally have a maximum path length.  Depending on your
$TEST_DIR, it may be exceeded and then all tests that create and use
Unix sockets there may fail.

Circumvent this by adding a new scratch directory specifically for
Unix socket files.  It defaults to a temporary directory (mktemp -d)
that is completely removed after the iotests are done.

(By default, mktemp -d creates a /tmp/tmp.XXXXXXXXXX directory, which
should be short enough for our use cases.)

Use mkdir -p to create the directory (because it seems right), and do
the same for $TEST_DIR (because there is no reason for that to be
created in any different way).

6be0122520 iotests: Allow skipping test cases
case_notrun() does not actually skip the current test case.  It just
adds a "notrun" note and then returns to the caller, who manually has to
skip the test.  Generally, skipping a test case is as simple as
returning from the current function, but not always: For example, this
model does not allow skipping tests already in the setUp() function.

Thus, add a QMPTestCase.case_skip() function that invokes case_notrun()
and then self.skipTest().  To make this work, we need to filter the
information on how many test cases were skipped from the unittest
output.

038adc2f58 core: replace getpagesize() with qemu_real_host_page_size
There are three page size in qemu:

  real host page size
  host page size
  target page size

All of them have dedicate variable to represent. For the last two, we
use the same form in the whole qemu project, while for the first one we
use two forms: qemu_real_host_page_size and getpagesize().

qemu_real_host_page_size is defined to be a replacement of
getpagesize(), so let it serve the role.

[Note] Not fully tested for some arch or device.

d926f4ddd2 iotests: Skip read-only cases in 118 when run as root
Some tests in 118 use chmod to remove write permissions from the file
and assume that the image can indeed not be opened read-write
afterwards. This doesn't work when the test is run as root, because root
can still open the file as writable even when the permission bit isn't
set.

Introduce a @skip_if_root decorator and use it in 118 to skip the tests
in question when the script is run as root.

d08f68b8e8 libqos: add VIRTIO PCI 1.0 support
Implement the VIRTIO 1.0 virtio-pci interface.  The main change here is
that the register layout is no longer a fixed layout in BAR 0.  Instead
we have to iterate of PCI Capabilities to find descriptions of where
various registers are located.  The vring registers are also more
fine-grained, allowing for more flexible vring layouts, but we don't
take advantage of that.

c0f79698ed libqos: implement VIRTIO 1.0 FEATURES_OK step
Device initialization has an extra step in VIRTIO 1.0.  The FEATURES_OK
status bit is set to indicate that feature negotiation has completed.
The driver then reads the status register again to check that the device
agrees with the final features.

Implement this step as part of qvirtio_set_features() instead of
introducing a separate function.  This way all existing code works
without modifications.

The check in qvirtio_set_driver_ok() needs to be updated because
FEATURES_OK will be set for VIRTIO 1.0 devices.

60ce3a40fc libqos: read QVIRTIO_MMIO_VERSION register
There was no real virtio-mmio ABI change between Legacy and VIRTIO 1.0
except that the Version field was incremented from 1 to 2.

However, QEMU does not allow Legacy drivers to perform VIRTIO 1.0
operations like accessing 64-bit feature bits.  Since we will introduce
64-bit feature bit support we need a way to differentiate between
virtio-mmio Version 1 and 2 to avoid upsetting QEMU when we operate in
Legacy mode.

Stash away the Version field so later patches can change behavior
depending on the version.

e6c42b96b9 qapi: Split up scripts/qapi/common.py
The QAPI code generator clocks in at some 3100 SLOC in 8 source files.
Almost 60% of the code is in qapi/common.py.  Split it into more
focused modules:

* Move QAPISchemaPragma and QAPISourceInfo to qapi/source.py.

* Move QAPIError and its sub-classes to qapi/error.py.

* Move QAPISchemaParser and QAPIDoc to parser.py.  Use the opportunity
  to put QAPISchemaParser first.

* Move check_expr() & friends to qapi/expr.py.  Use the opportunity to
  put the code into a more sensible order.

* Move QAPISchema & friends to qapi/schema.py

* Move QAPIGen and its sub-classes, ifcontext,
  QAPISchemaModularCVisitor, and QAPISchemaModularCVisitor to qapi/gen.py

* Delete camel_case(), it's unused since commit e98859a9b9 "qapi:
  Clean up after recent conversions to QAPISchemaVisitor"

A number of helper functions remain in qapi/common.py.  I considered
moving the code generator helpers to qapi/gen.py, but decided not to.
Perhaps we should rewrite them as methods of QAPIGen some day.

f01338cce6 qapi: Speed up frontend tests
"make check-qapi-schema" takes around 10s user + system time for me.
With -j, it takes a bit over 3s real time.  We have worse tests.  It's
still annoying when you work on the QAPI generator.

Some 1.4s user + system time is consumed by make figuring out what to
do, measured by making a target that does nothing.  There's nothing I
can do about that right now.  But let's see what we can do about the
other 8s.

Almost 7s are spent running test-qapi.py for every test case, the rest
normalizing and diffing test-qapi.py output.  We have 190 test cases.

If I downgrade to python2, it's 4.5s, but python2 is a goner.

Hacking up test-qapi.py to exit(0) without doing anything makes it
only marginally faster.  The problem is Python startup overhead.

Our configure puts -B into $(PYTHON).  Running without -B is faster:
4.4s.

We could improve the Makefile to run test cases only when the test
case or the generator changed.  But I'm after improvement in the case
where the generator changed.

test-qapi.py is designed to be the simplest possible building block
for a shell script to do the complete job (it's actually a Makefile,
not a shell script; no real difference).  Python is just not meant for
that.  It's for bigger blocks.

Move the post-processing and diffing into test-qapi.py, and make it
capable of testing multiple schema files.  Set executable bits while
there.

Running it once per test case now takes slightly longer than 8s.  But
running it once for all of them takes under 0.2s.

Messing with the Makefile to run it only on the tests that need
retesting is clearly not worth the bother.

Expected error output changes because the new normalization strips off
$(SRCDIR)/tests/qapi-schema/ instead of just $(SRCDIR)/.

The .exit files go away, because there is no exit status to test
anymore.

f3d4aa5add qapi: Don't suppress doc generation without pragma doc-required
Commit bc52d03ff5 "qapi: Make doc comments optional where we don't
need them" made scripts/qapi2texi.py fail[*] unless the schema had
pragma 'doc-required': true.  The stated reason was inability to cope
with incomplete documentation.

When commit fb0bc835e5 "qapi-gen: New common driver for code and doc
generators" folded scripts/qapi2texi.py into scripts/qapi-gen.py, it
turned the failure into silent suppression.

The doc generator can cope with incomplete documentation now.  I don't
know since when, or what the problem was, or even whether it ever
existed.

Drop the silent suppression.

[*] The fail part was broken, fixed in commit e8ba07ea9a.

48557b1383 util/hbitmap: strict hbitmap_reset
hbitmap_reset has an unobvious property: it rounds requested region up.
It may provoke bugs, like in recently fixed write-blocking mode of
mirror: user calls reset on unaligned region, not keeping in mind that
there are possible unrelated dirty bytes, covered by rounded-up region
and information of this unrelated "dirtiness" will be lost.

Make hbitmap_reset strict: assert that arguments are aligned, allowing
only one exception when @start + @count == hb->orig_size. It's needed
to comfort users of hbitmap_next_dirty_area, which cares about
hb->orig_size.

021a007efc tests: cpu-plug-test: fix device_add for pc/q35 machines
Commit bc1fb850a3 silently broke device_add test for CPU hotplug which
resulted in test successfully passing though it wasn't actually run.
Fix it by making sure that all non present CPUs reported
by "query-hotpluggable-cpus" are hotplugged instead of making up
and hardcoding values.

Use of query-hotpluggable-cpus also allows consolidatiate device_add
cpu testcases and reuse the same test function for all targets.

While at it also add a check that at least one CPU was hotplugged,
to avoid silent breakage in the future.

Fixes: bc1fb850a3 (vl.c deprecate incorrect CPUs topology)

b01422622b ptimer: Rename ptimer_init() to ptimer_init_with_bh()
Currently the ptimer design uses a QEMU bottom-half as its
mechanism for calling back into the device model using the
ptimer when the timer has expired. Unfortunately this design
is fatally flawed, because it means that there is a lag
between the ptimer updating its own state and the device
callback function updating device state, and guest accesses
to device registers between the two can return inconsistent
device state.

We want to replace the bottom-half design with one where
the guest device's callback is called either immediately
(when the ptimer triggers by timeout) or when the device
model code closes a transaction-begin/end section (when the
ptimer triggers because the device model changed the
ptimer's count value or other state). As the first step,
rename ptimer_init() to ptimer_init_with_bh(), to free up
the ptimer_init() name for the new API. We can then convert
all the ptimer users away from ptimer_init_with_bh() before
removing it entirely.

(Commit created with
 git grep -l ptimer_init | xargs sed -i -e 's/ptimer_init/ptimer_init_with_bh/'
and three overlong lines folded by hand.)

a1406a9262 iotests: Test large write request to qcow2 file
Without HEAD^, the following happens when you attempt a large write
request to a qcow2 file such that the number of bytes covered by all
clusters involved in a single allocation will exceed INT_MAX:

(A) handle_alloc_space() decides to fill the whole area with zeroes and
    fails because bdrv_co_pwrite_zeroes() fails (the request is too
    large).

(B) If handle_alloc_space() does not do anything, but merge_cow()
    decides that the requests can be merged, it will create a too long
    IOV that later cannot be written.

(C) Otherwise, all parts will be written separately, so those requests
    will work.

In either B or C, though, qcow2_alloc_cluster_link_l2() will have an
overflow: We use an int (i) to iterate over nb_clusters, and then
calculate the L2 entry based on "i << s->cluster_bits" -- which will
overflow if the range covers more than INT_MAX bytes.  This then leads
to image corruption because the L2 entry will be wrong (it will be
recognized as a compressed cluster).

Even if that were not the case, the .cow_end area would be empty
(because handle_alloc() will cap avail_bytes and nb_bytes at INT_MAX, so
their difference (which is the .cow_end size) will be 0).

So this test checks that on such large requests, the image will not be
corrupted.  Unfortunately, we cannot check whether COW will be handled
correctly, because that data is discarded when it is written to null-co
(but we have to use null-co, because writing 2 GB of data in a test is
not quite reasonable).

48c8d3ce6d iotests/028: Fix for long $TEST_DIRs
For long test image paths, the order of the "Formatting" line and the
"(qemu)" prompt after a drive_backup HMP command may be reversed.  In
fact, the interaction between the prompt and the line may lead to the
"Formatting" to being greppable at all after "read"-ing it (if the
prompt injects an IFS character into the "Formatting" string).

So just wait until we get a prompt.  At that point, the block job must
have been started, so "info block-jobs" will only return "No active
jobs" once it is done.

f2208fdc5b block: Reject misaligned write requests with BDRV_REQ_NO_FALLBACK
The BDRV_REQ_NO_FALLBACK flag means that an operation should only be
performed if it can be offloaded or otherwise performed efficiently.

However a misaligned write request requires a RMW so we should return
an error and let the caller decide how to proceed.

This hits an assertion since commit c8bb23cbdb if the required
alignment is larger than the cluster size:

qemu-img create -f qcow2 -o cluster_size=2k img.qcow2 4G
qemu-io -c "open -o driver=qcow2,file.align=4k blkdebug::img.qcow2" \
        -c 'write 0 512'
qemu-io: block/io.c:1127: bdrv_driver_pwritev: Assertion `!(flags & BDRV_REQ_NO_FALLBACK)' failed.
Aborted

The reason is that when writing to an unallocated cluster we try to
skip the copy-on-write part and zeroize it using BDRV_REQ_NO_FALLBACK
instead, resulting in a write request that is too small (2KB cluster
size vs 4KB required alignment).

69de48445a test-bdrv-drain: fix iothread_join() hang
tests/test-bdrv-drain can hang in tests/iothread.c:iothread_run():

  while (!atomic_read(&iothread->stopping)) {
      aio_poll(iothread->ctx, true);
  }

The iothread_join() function works as follows:

  void iothread_join(IOThread *iothread)
  {
      iothread->stopping = true;
      aio_notify(iothread->ctx);
      qemu_thread_join(&iothread->thread);

If iothread_run() checks iothread->stopping before the iothread_join()
thread sets stopping to true, then aio_notify() may be optimized away
and iothread_run() hangs forever in aio_poll().

The correct way to change iothread->stopping is from a BH that executes
within iothread_run().  This ensures that iothread->stopping is checked
after we set it to true.

This was already fixed for ./iothread.c (note this is a different source
file!) by commit 2362a28ea1 ("iothread:
fix iothread_stop() race condition"), but not for tests/iothread.c.

9a85e4b8f6 migration: Support gtree migration
Introduce support for GTree migration. A custom save/restore
is implemented. Each item is made of a key and a data.

If the key is a pointer to an object, 2 VMSDs are passed into
the GTree VMStateField.

When putting the items, the tree is traversed in sorted order by
g_tree_foreach.

On the get() path, gtrees must be allocated using the proper
key compare, key destroy and value destroy. This must be handled
beforehand, for example in a pre_load method.

Tests are added to test save/dump of structs containing gtrees
including the virtio-iommu domain/mappings scenario.

35f05b2e2e iotests/162: Fix for newer Linux 5.3+
Linux 5.3 has made 0.0.0.0/8 a working IPv4 subnet.  As such, "42" is
now a valid host, and the connection to it will (hopefully) time out
over a long period rather than quickly return with EINVAL.

So let us use a negative integer for testing that NBD will not crash
when it receives integer hosts.  This way, the connection will again
fail quickly and reliably.

00e30f05de block/backup: use backup-top instead of write notifiers
Drop write notifiers and use filter node instead.

= Changes =

1. Add filter-node-name argument for backup qmp api. We have to do it
in this commit, as 257 needs to be fixed.

2. There are no more write notifiers here, so is_write_notifier
parameter is dropped from block-copy paths.

3. To sync with in-flight requests at job finish we now have drained
removing of the filter, we don't need rw-lock.

4. Block-copy is now using BdrvChildren instead of BlockBackends

5. As backup-top owns these children, we also move block-copy state
into backup-top's ownership.

= Iotest changes =

56: op-blocker doesn't shoot now, as we set it on source, but then
check on filter, when trying to start second backup.
To keep the test we instead can catch another collision: both jobs will
get 'drive0' job-id, as job-id parameter is unspecified. To prevent
interleaving with file-posix locks (as they are dependent on config)
let's use another target for second backup.

Also, it's obvious now that we'd like to drop this op-blocker at all
and add a test-case for two backups from one node (to different
destinations) actually works. But not in these series.

141: Output changed: prepatch, "Node is in use" comes from bdrv_has_blk
check inside qmp_blockdev_del. But we've dropped block-copy blk
objects, so no more blk objects on source bs (job blk is on backup-top
filter bs). New message is from op-blocker, which is the next check in
qmp_blockdev_add.

257: The test wants to emulate guest write during backup. They should
go to filter node, not to original source node, of course. Therefore we
need to specify filter node name and use it.

And by that I mean all XFS versions, as far as I can tell.  All details

We never noticed this problem because we only read the first number from

because qemu-img prints a human-readable value (which generally includes
a decimal point).  That will be fixed in the next patch.
