346f3dab04 migration: add blocktime calculation into migration-test
This patch just requests blocktime calculation,
and check it in case when UFFD_FEATURE_THREAD_ID feature is set
on the host.

25bf2426f3 iotests: fix 169
Improve and fix 169:
    - use MIGRATION events instead of RESUME
    - make a TODO: enable dirty-bitmaps capability for offline case
    - recreate vm_b without -incoming near test end

This (likely) fixes racy faults at least of the following types:

    - timeout on waiting for RESUME event
    - sha256 mismatch on line 136 (142 after this patch)
    - fail to self.vm_b.launch() on line 135 (141 now after this patch)

And surely fixes cat processes, left after test finish.

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()")

Also, add an assert (we don't want set both arguments) and remove

c3988519c4 iotests: fix wait_until_completed()
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

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

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.

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).

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.

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.

a4f90923b5 Revert "monitor: enable IO thread for (qmp & !mux) typed"
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
QMPCapability", 2018-03-19), as both parts must be reverted at once
to keep 'make check' passing.

cc797607c0 Revert "tests: qmp-test: verify command batching"
This reverts commit 91ad45061a.

Enabling OOB caused several iotests failures; due to the imminent
2.12 release, the safest action is to disable OOB, but first we
have to revert tests that rely on OOB.
