4160280776 softfloat: fix floatx80 pseudo-denormal addition / subtraction
The softfloat function addFloatx80Sigs, used for addition of values
with the same sign and subtraction of values with opposite sign, fails
to handle the case where the two values both have biased exponent zero
and there is a carry resulting from adding the significands, which can
occur if one or both values are pseudo-denormals (biased exponent
zero, explicit integer bit 1).  Add a check for that case, so making
the results match those seen on x86 hardware for pseudo-denormals.

7537c2b4a3 softfloat: silence sNaN for conversions to/from floatx80
Conversions between IEEE floating-point formats should convert
signaling NaNs to quiet NaNs.  Most of those in QEMU's softfloat code
do so, but those for floatx80 fail to.  Fix those conversions to
silence signaling NaNs as well.

df4fe0b291 qom: Drop @errp parameter of object_property_del()
Same story as for object_property_add(): the only way
object_property_del() can fail is when the property with this name
does not exist.  Since our property names are all hardcoded, failure
is a programming error, and the appropriate way to handle it is
passing &error_abort.  Most callers do that, the commit before
previous fixed one that didn't (and got the error handling wrong), and
the two remaining exceptions ignore errors.

Drop the @errp parameter.

d2623129a7 qom: Drop parameter @errp of object_property_add() & friends
The only way object_property_add() can fail is when a property with
the same name already exists.  Since our property names are all
hardcoded, failure is a programming error, and the appropriate way to
handle it is passing &error_abort.

Same for its variants, except for object_property_add_child(), which
additionally fails when the child already has a parent.  Parentage is
also under program control, so this is a programming error, too.

We have a bit over 500 callers.  Almost half of them pass
&error_abort, slightly fewer ignore errors, one test case handles
errors, and the remaining few callers pass them to their own callers.

The previous few commits demonstrated once again that ignoring
programming errors is a bad idea.

Of the few ones that pass on errors, several violate the Error API.
The Error ** argument must be NULL, &error_abort, &error_fatal, or a
pointer to a variable containing NULL.  Passing an argument of the
latter kind twice without clearing it in between is wrong: if the
first call sets an error, it no longer points to NULL for the second
call.  ich9_pm_add_properties(), sparc32_ledma_realize(),
sparc32_dma_realize(), xilinx_axidma_realize(), xilinx_enet_realize()
are wrong that way.

When the one appropriate choice of argument is &error_abort, letting
users pick the argument is a bad idea.

Drop parameter @errp and assert the preconditions instead.

There's one exception to "duplicate property name is a programming
error": the way object_property_add() implements the magic (and
undocumented) "automatic arrayification".  Don't drop @errp there.
Instead, rename object_property_add() to object_property_try_add(),
and add the obvious wrapper object_property_add().

572ad9783f qcow2: introduce compression type feature
The patch adds some preparation parts for incompatible compression type
feature to qcow2 allowing the use different compression methods for
image clusters (de)compressing.

It is implied that the compression type is set on the image creation and
can be changed only later by image conversion, thus compression type
defines the only compression algorithm used for the image, and thus,
for all image clusters.

The goal of the feature is to add support of other compression methods
to qcow2. For example, ZSTD which is more effective on compression than ZLIB.

The default compression is ZLIB. Images created with ZLIB compression type
are backward compatible with older qemu versions.

Adding of the compression type breaks a number of tests because now the
compression type is reported on image creation and there are some changes
in the qcow2 header in size and offsets.

The tests are fixed in the following ways:
    * filter out compression_type for many tests
    * fix header size, feature table size and backing file offset
      affected tests: 031, 036, 061, 080
      header_size +=8: 1 byte compression type
                       7 bytes padding
      feature_table += 48: incompatible feature compression type
      backing_file_offset += 56 (8 + 48 -> header_change + feature_table_change)
    * add "compression type" for test output matching when it isn't filtered
      affected tests: 049, 060, 061, 065, 082, 085, 144, 182, 185, 198, 206,
                      242, 255, 274, 280

6a9d73bdd0 iotests/055: Use cache.no-flush for vmdk target
055 uses the backup block job to create a compressed backup of an
$IMGFMT image with both qcow2 and vmdk targets. However, cluster
allocation in vmdk is very slow because it flushes the image file after
each L2 update.

There is no reason why we need this level of safety in this test, so
let's disable flushes for vmdk. For the blockdev-backup tests this is
achieved by simply adding the cache.no-flush=on to the drive_add() for
the target. For drive-backup, the caching flags are copied from the
source node, so we'll also add the flag to the source node, even though
it is not vmdk.

This can make the test run significantly faster (though it doesn't make
a difference on tmpfs). In my usual setup it goes from ~45s to ~15s.

e4d7019e1a qcow2: Avoid integer wraparound in qcow2_co_truncate()
After commit f01643fb8b when an image is
extended and BDRV_REQ_ZERO_WRITE is set then the new clusters are
zeroized.

The code however does not detect correctly situations when the old and
the new end of the image are within the same cluster. The problem can
be reproduced with these steps:

   qemu-img create -f qcow2 backing.qcow2 1M
   qemu-img create -f qcow2 -F qcow2 -b backing.qcow2 top.qcow2
   qemu-img resize --shrink top.qcow2 520k
   qemu-img resize top.qcow2 567k

In the last step offset - zero_start causes an integer wraparound.

d2fefdedd3 tests/tcg: better trap gdb failures
It seems older and non-multiarach aware GDBs might not fail gracefully
when faced with something they don't know. For example when faced with
a target XML for s390x the Ubuntu 18.04 gdb will generate an internal
fault and prompt for a core dump.

Work around this by invoking GDB in a more batch orientated way and
then trying to filter out between test failures and gdb failures.

7fa140abf6 qcow2: Allow resize of images with internal snapshots
We originally refused to allow resize of images with internal
snapshots because the v2 image format did not require the tracking of
snapshot size, making it impossible to safely revert to a snapshot
with a different size than the current view of the image.  But the
snapshot size tracking was rectified in v3, and our recent fixes to
qemu-img amend (see 0a85af35) guarantee that we always have a valid
snapshot size.  Thus, we no longer need to artificially limit image
resizes, but it does become one more thing that would prevent a
downgrade back to v2.  And now that we support different-sized
snapshots, it's also easy to fix reverting to a snapshot to apply the
new size.

Upgrade iotest 61 to cover this (we previously had NO coverage of
refusal to resize while snapshots exist).  Note that the amend process
can fail but still have effects: in particular, since we break things
into upgrade, resize, downgrade, a failure during resize does not roll
back changes made during upgrade, nor does failure in downgrade roll
back a resize.  But this situation is pre-existing even without this
patch; and without journaling, the best we could do is minimize the
chance of partial failure by collecting all changes prior to doing any
writes - which adds a lot of complexity but could still fail with EIO.
On the other hand, we are careful that even if we have partial
modification but then fail, the image is left viable (that is, we are
careful to sequence things so that after each successful cluster
write, there may be transient leaked clusters but no corrupt
metadata).  And complicating the code to make it more transaction-like
is not worth the effort: a user can always request multiple 'qemu-img
amend' changing one thing each, if they need finer-grained control
over detecting the first failure than what they get by letting qemu
decide how to sequence multiple changes.

52ea799e96 iotests: use python logging for iotests.log()
We can turn logging on/off globally instead of per-function.

Remove use_log from run_job, and use python logging to turn on
diffable output when we run through a script entry point.

iotest 245 changes output order due to buffering reasons.

An extended note on python logging:

A NullHandler is added to `qemu.iotests` to stop output from being
generated if this code is used as a library without configuring logging.
A NullHandler is only needed at the root, so a duplicate handler is not
needed for `qemu.iotests.diff_io`.

When logging is not configured, messages at the 'WARNING' levels or
above are printed with default settings. The NullHandler stops this from
occurring, which is considered good hygiene for code used as a library.

See https://docs.python.org/3/howto/logging.html#library-config

When logging is actually enabled (always at the behest of an explicit
call by a client script), a root logger is implicitly created at the
root, which allows messages to propagate upwards and be handled/emitted
from the root logger with default settings.

When we want iotest logging, we attach a handler to the
qemu.iotests.diff_io logger and disable propagation to avoid possible
double-printing.

For more information on python logging infrastructure, I highly
recommend downloading the pip package `logging_tree`, which provides
convenient visualizations of the hierarchical logging configuration
under different circumstances.

See https://pypi.org/project/logging_tree/ for more information.

239bbcc0ae iotests: add hmp helper with logging
Minor cleanup for HMP functions; helps with line length and consolidates
HMP helpers through one implementation function.

Although we are adding a universal toggle to turn QMP logging on or off,
many existing callers to hmp functions don't expect that output to be
logged, which causes quite a few changes in the test output.

For now, offer a use_log parameter.

Typing notes:

QMPResponse is just an alias for Dict[str, Any]. It holds no special
meanings and it is not a formal subtype of Dict[str, Any]. It is best
thought of as a lexical synonym.

We may well wish to add stricter subtypes in the future for certain
shapes of data that are not formalized as Python objects, at which point
we can simply retire the alias and allow mypy to more strictly check
usages of the name.

1cd0dbfc12 iotests: touch up log function signature
Representing nested, recursive data structures in mypy is notoriously
difficult; the best we can reliably do right now is denote the leaf
types as "Any" while describing the general shape of the data.

Regardless, this fully annotates the log() function.

Typing notes:

TypeVar is a Type variable that can optionally be constrained by a
sequence of possible types. This variable is bound to a specific type
per-invocation, like a Generic.

log() behaves as log<Msg>() now, where the incoming type informs the
signature it expects for any filter arguments passed in. If Msg is a
str, then filter should take and return a str.

05509c8e6d fuzz: select fuzz target using executable name
The fuzzers are built into a binary (e.g. qemu-fuzz-i386). To select the
device to fuzz/fuzz target, we usually use the --fuzz-target= argument.
This commit allows the fuzz-target to be specified using the name of the
executable. If the executable name ends with -target-FUZZ_TARGET, then
we select the fuzz target based on this name, rather than the
--fuzz-target argument. This is useful for systems such as oss-fuzz
where we don't have control of the arguments passed to the fuzzer.

[Fixed incorrect indentation.

71b0269ae9 hw/acpi/nvdimm: Fix for NVDIMM incorrect DSM output buffer length
As per ACPI spec 6.3, Table 19-419 Object Conversion Rules, if
the Buffer Field <= to the size of an Integer (in bits), it will
be treated as an integer. Moreover, the integer size depends on
DSDT tables revision number. If revision number is < 2, integer
size is 32 bits, otherwise it is 64 bits. Current NVDIMM common
DSM aml code (NCAL) uses CreateField() for creating DSM output
buffer. This creates an issue in arm/virt platform where DSDT
revision number is 2 and results in DSM buffer with a wrong
size(8 bytes) gets returned when actual length is < 8 bytes.
This causes guest kernel to report,

"nfit ACPI0012:00: found a zero length table '0' parsing nfit"

In order to fix this, aml code is now modified such that it builds
the DSM output buffer in a byte by byte fashion when length is
smaller than Integer size.

eb8a0cf3ba qcow2: Forward ZERO_WRITE flag for full preallocation
The BDRV_REQ_ZERO_WRITE is currently implemented in a way that first the
image is possibly preallocated and then the zero flag is added to all
clusters. This means that a copy-on-write operation may be needed when
writing to these clusters, despite having used preallocation, negating
one of the major benefits of preallocation.

Instead, try to forward the BDRV_REQ_ZERO_WRITE to the protocol driver,
and if the protocol driver can ensure that the new area reads as zeros,
we can skip setting the zero flag in the qcow2 layer.

Unfortunately, the same approach doesn't work for metadata
preallocation, so we'll still set the zero flag there.

3fb6108707 qemu-iotests: allow qcow2 external discarded clusters to contain stale data
Test 244 checks the expected behavior of qcow2 external data files
with respect to zero and discarded clusters.  Filesystems however
are free to ignore discard requests, and this seems to be the
case for overlayfs.  Relax the tests to skip checks on the
external data file for discarded areas, which implies not using
qemu-img compare in the data_file_raw=on case.

This fixes docker tests on RHEL8.

a56f3cdbdf fuzz: Simplify how we compute available machines and types
apply_to_qlist(), apply_to_node() work with QObjects.  This is
designed for use by tests/qtest/qos-test.c, which gets the data in
that form via QMP.  Goes back to commit fc281c8020 "tests: qgraph API
for the qtest driver framework".

Commit 275ab39d86 "fuzz: add support for qos-assisted fuzz targets"
added another user: qtest/fuzz/qos_fuzz.c.  To get the data as
QObjects, it uses qmp_marshal_query_machines() and
qmp_marshal_qom_list_types().

All this code is rather cumbersome.  Switch to working with generated
QAPI types instead:

* Replace apply_to_qlist() & friends by machines_apply_to_node() and
  types_apply_to_node().

* Have qos_fuzz.c use qmp_query_machines() and qmp_qom_list_types()

551affb61e tests/docker: add docs FEATURE flag and use for test-misc
The test-misc docker test fails on a number of images which don't have
the prerequisites to build the docs. Use the FEATURES flag so we can
skip those tests.

As the sphinx test fails to detect whatever feature we need to get
hxtool to work we drop them from debian9 so the windows build doesn't
attempt to build the docs.

9a709f06c8 piix: fix xenfv regression, add compat machine xenfv-4.2
With QEMU 4.0 an incompatible change was added to pc_piix, which makes it
practical impossible to migrate domUs started with qemu2 or qemu3 to
newer qemu versions. Commit 7fccf2a068
added and enabled a new member "smbus_no_migration_support". In commit
4ab2f2a8aa the vmstate_acpi got new
elements, which are conditionally filled. As a result, an incoming
migration expected smbus related data unless smbus migration was
disabled for a given MachineClass. Since first commit forgot to handle
'xenfv', domUs started with QEMU 4.x are incompatible with their QEMU
siblings.

Using other existing machine types, such as 'pc-i440fx-3.1', is not
possible because 'xenfv' creates the 'xen-platform' PCI device at
00:02.0, while all other variants to run a domU would create it at
00:04.0.

To cover both the existing and the broken case of 'xenfv' in a single
qemu binary, a new compatibility variant of 'xenfv-4.2' must be added
which targets domUs started with qemu 4.2. The existing 'xenfv' restores
compatibility of QEMU 5.x with qemu 3.1.

Host admins who started domUs with QEMU 4.x (preferrable QEMU 4.2)
have to use a wrapper script which appends '-machine xenfv-4.2' to
the device-model command line.  This is only required if there is no
maintenance window which allows to temporary shutdown the domU and
restart it with a fixed device-model.

The wrapper script is as simple as this:
  #!/bin/sh
  exec /usr/bin/qemu-system-i386 "$@" -machine xenfv-4.2

With xl this script will be enabled with device_model_override=, see
xl.cfg(5). To live migrate a domU, adjust the existing domU.cfg and pass
it to xl migrate or xl save/restore:
  xl migrate -C new-domU.cfg domU remote-host
  xl save domU CheckpointFile new-domU.cfg
  xl restore new-domU.cfg CheckpointFile

With libvirt this script will be enabled with the <emulator> element in
domU.xml. Use 'virsh edit' prior 'virsh migrate' to replace the existing
<emulator> element to point it to the wrapper script.

b660a84bbb job: take each job's lock individually in job_txn_apply
All callers of job_txn_apply hold a single job's lock, but different
jobs within a transaction can have different contexts, thus we need to
lock each one individually before applying the callback function.

Similar to job_completed_txn_abort this also requires releasing the
caller's context before and reacquiring it after to avoid recursive
locks which might break AIO_WAIT_WHILE in the callback. This is safe, since
existing code would already have to take this into account, lest
job_completed_txn_abort might have broken.

This also brings to light a different issue: When a callback function in
job_txn_apply moves it's job to a different AIO context, callers will
try to release the wrong lock (now that we re-acquire the lock
correctly, previously it would just continue with the old lock, leaving
the job unlocked for the rest of the return path). Fix this by not caching
the job's context.

This is only necessary for qmp_block_job_finalize, qmp_job_finalize and
job_exit, since everyone else calls through job_exit.

One test needed adapting, since it calls job_finalize directly, so it
manually needs to acquire the correct context.

80f5c01183 qcow2: Forbid discard in qcow2 v2 images with backing files
A discard request deallocates the selected clusters so they read back
as zeroes. This is done by clearing the cluster offset field and
setting QCOW_OFLAG_ZERO in the L2 entry.

This flag is however only supported when qcow_version >= 3. In older
images the cluster is simply deallocated, exposing any possible stale
data from the backing file.

Since discard is an advisory operation it's safer to simply forbid it
in this scenario.

Note that we are adding this check to qcow2_co_pdiscard() and not to
qcow2_cluster_discard() or discard_in_l2_slice() because the last
two are also used by qcow2_snapshot_create() to discard the clusters
used by the VM state. In this case there's no risk of exposing stale
data to the guest and we really want that the clusters are always
discarded.

5baecf58ad tests/acceptance/machine_sparc_leon3: Disable HelenOS test
This test was written/tested around beginning of 2019, but was
extracted from a bigger series and posted end of June 2019 [*].
Unfortunately I did not notice commit 162abf1a8 was merged by
then, which implements the AHB and APB plug and play devices.

HelenOS 0.6 is expecting the PnP registers to be not implemented
by QEMU, then forces the discovered AMBA devices (see [2]).

Before 162abf1a8, the console was displaying:

As this test is not working as expected, simply disable it (by
skipping it) for now.

1153cf9f5b qtest: add tulip test case
The tulip networking card emulation has an OOB issue in
'tulip_copy_tx_buffers' when the guest provide malformed descriptor.
This test will trigger a ASAN heap overflow crash. To trigger this
issue we can construct the data as following:

1. construct a 'tulip_descriptor'. Its control is set to
'0x7ff | 0x7ff << 11', this will make the 'tulip_copy_tx_buffers's
'len1' and 'len2' to 0x7ff(2047). So 'len1+len2' will overflow
'TULIPState's 'tx_frame' field. This descriptor's 'buf_addr1' and
'buf_addr2' should set to a guest address.

2. write this descriptor to tulip device's CSR4 register. This will
set the 'TULIPState's 'current_tx_desc' field.

3. write 'CSR6_ST' to tulip device's CSR6 register. This will trigger
'tulip_xmit_list_update' and finally calls 'tulip_copy_tx_buffers'.

Following shows the backtrack of crash:

==31781==ERROR: AddressSanitizer: heap-buffer-overflow on address 0x628000007cd0 at pc 0x7fe03c5a077a bp 0x7fff05b46770 sp 0x7fff05b45f18

9274ae32c3 tests/docker: Install gcrypt devel package in Debian image

on the the Debian 'x86 host', which was based on Debian Stretch.
Later in commit 698a71edbe we upgraded the Debian base image to
Buster.

Apparently Debian Stretch was listing gcrypt as a QEMU dependency,
but this is not the case anymore in Buster, so we need to install
it manually (it it not listed by 'apt-get -s build-dep qemu' in
the common debian10.docker anymore). This fixes:

 $ ../configure $QEMU_CONFIGURE_OPTS

a507c51790 iotests/138: Test leaks/corruptions fixed report
Test that qemu-img check reports the number of leaks and corruptions
fixed in its JSON report (after a successful run).

While touching the _unsupported_imgopts line, adjust the note on why
data_file does not work with this test: The current comment sounds a bit
like it is a mistake for qemu-img check not to check external data
files' refcounts.  But there are no such refcounts, so it is no mistake.
Just say that qemu-img check does not do much for external data files,
and this is why this test does not work with them.

e7be13ad3f qcow2: Avoid feature name extension on small cluster size
As the feature name table can be quite large (over 9k if all 64 bits
of all three feature fields have names; a mere 8 features leaves only
8 bytes for a backing file name in a 512-byte cluster), it is unwise
to emit this optional header in images with small cluster sizes.

Update iotest 036 to skip running on small cluster sizes; meanwhile,
note that iotest 061 never passed on alternative cluster sizes
(however, I limited this patch to tests with output affected by adding
feature names, rather than auditing for other tests that are not
robust to alternative cluster sizes).

Per David Gilbert, "it could just be the writing is slow on s390
and the migration thread fast; in which case the autocomplete

limit."

Tuning the threshold by reducing the initial bandwidth makes the
autoconverge test pass.

299ea9ff01 block/dirty-bitmap: improve _next_dirty_area API
Firstly, _next_dirty_area is for scenarios when we may contiguously
search for next dirty area inside some limited region, so it is more
comfortable to specify "end" which should not be recalculated on each
iteration.

Secondly, let's add a possibility to limit resulting area size, not
limiting searching area. This will be used in NBD code in further
commit. (Note that now bdrv_dirty_bitmap_next_dirty_area is unused)

We have bdrv_dirty_bitmap_next_zero, let's add corresponding

bitmap iterators in some cases.

For test modify test_hbitmap_next_zero_check_range to check both
next_zero and next_dirty and add some new checks.

642700fda0 block/dirty-bitmap: switch _next_dirty_area and _next_zero to int64_t
We are going to introduce bdrv_dirty_bitmap_next_dirty so that same
variable may be used to store its return value and to be its parameter,
so it would int64_t.

Similarly, we are going to refactor hbitmap_next_dirty_area to use
hbitmap_next_dirty together with hbitmap_next_zero, therefore we want
hbitmap_next_zero parameter type to be int64_t too.

So, for convenience update all parameters of *_next_zero and
*_next_dirty_area to be int64_t.

a51d6a5493 tests/docker: make "buildah bud" output similar to "docker build"
Podman users will most often be using buildah to build containers.
Among the differences between "buildah bud|build-using-dockerfile" and
a traditional "docker build" is that buildah does not run a container
during build.

To the best of my knowledge and experiments, this means that runtime
variables, such as ENV from one base image will not propagate into
another.  The end result is that the location for the cross compiler
binaries, defined in the base "qemu/debian9-mxe" image, are not passed
through this image.  Consequently, the cross compilers are not on PATH
and the build fails.

4ec49f0fcd Acceptance tests: add make targets to download images
The newly introduced "boot linux" tests make use of Linux images that
are larger than usual, and fall into what Avocado calls "vmimages",
and can be referred to by name, version and architecture.

The images can be downloaded automatically during the test. But, to
make for more reliable test results, this introduces a target that
will download the vmimages for the architectures that have been
configured and are available for the currently used distro (Fedora
31).

6fd52d671d Acceptance test: add "boot_linux" tests
This acceptance test, validates that a full blown Linux guest can
successfully boot in QEMU.  In this specific case, the guest chosen is
Fedora version 31.

 * x86_64, pc-i440fx and pc-q35 machine types, with TCG and KVM as
   accelerators

 * aarch64 and virt machine type, with TCG and KVM as accelerators

 * ppc64 and pseries machine type with TCG as accelerator

 * s390x and s390-ccw-virtio machine type with TCG as accelerator

The Avocado vmimage utils library is used to download and cache the
Linux guest images, and from those images a snapshot image is created
and given to QEMU.  If a qemu-img binary is available in the build
directory, it's used to create the snapshot image, so that matching
qemu-system-* and qemu-img are used in the same test run.  If qemu-img
is not available in the build tree, one is attempted to be found
installed system-wide (in the $PATH).  If qemu-img is not found in the
build dir or in the $PATH, the test is canceled.

The method for checking the successful boot is based on "cloudinit"
and its "phone home" feature.  The guest is given an ISO image with
the location of the phone home server, and the information to post
(the instance ID).  Upon receiving the correct information, from the
guest, the test is considered to have PASSed.

This test is currently limited to user mode networking only, and
instructs the guest to connect to the "router" address that is hard
coded in QEMU.

To create the cloudinit ISO image that will be used to configure the
guest, the pycdlib library is also required and has been added as
requirement to the virtual environment created by "check-venv".

The console output is read by a separate thread, by means of the
Avocado datadrainer utility module.

b44513b13d Acceptance tests: introduce BUILD_DIR and SOURCE_DIR
Some tests may benefit from using resources from a build directory.
This introduces three variables that can help tests find resources in
those directories.

First, a BUILD_DIR is assumed to exist, given that the primary form of
running the acceptance tests is from a build directory (which may or
may not be the same as the source tree, that is, the SOURCE_DIR).

If the directory containing the acceptance tests happens to be a link
to a directory, it's assumed to it points to the source tree
(SOURCE_DIR), which is the behavior defined on the QEMU Makefiles.  If
the directory containing the acceptance tests is not a link, then a
in-tree build is assumed, and the BUILD_DIR and SOURCE_DIR have the
same value.

2b6d6371a9 tests/tcg/aarch64: add SVE iotcl test
This is a fairly bare-bones test of setting the various vector sizes
for SVE which will only fail if the PR_SVE_SET_VL can't reduce the
user-space vector length by powers of 2.

However we will also be able to use it in a future test which
exercises the GDB stub.

f7795e4096 misc: Replace zero-length arrays with flexible array member (automatic)
Description copied from Linux kernel commit from Gustavo A. R. Silva
(see [3]):

--v-- description start --v--

  The current codebase makes use of the zero-length array language
  extension to the C90 standard, but the preferred mechanism to
  declare variable-length types such as these ones is a flexible
  array member [1], introduced in C99:

  struct foo {
      int stuff;
      struct boo array[];
  };

  By making use of the mechanism above, we will get a compiler
  warning in case the flexible array does not occur last in the
  structure, which will help us prevent some kind of undefined
  behavior bugs from being unadvertenly introduced [2] to the
  Linux codebase from now on.

--^-- description end --^--

Do the similar housekeeping in the QEMU codebase (which uses
C99 since commit 7be41675f7).

All these instances of code were found with the help of the
following Coccinelle script:

  @@
  identifier s, m, a;
  type t, T;
  @@
   struct s {
      ...
      t m;
  -   T a[0];
  +   T a[];
  };
  @@
  identifier s, m, a;
  type t, T;
  @@
   struct s {
      ...
      t m;
  -   T a[0];
  +   T a[];
   } QEMU_PACKED;

This test boots U-Boot then NetBSD (stored on a SD card) on
a OrangePi PC board.

As it requires ~1.3GB of storage, it is disabled by default.

U-Boot is built by the Debian project [1], and the SD card image
is provided by the NetBSD organization [2].

Once the compressed SD card image is downloaded (304MB) and
extracted, this test is fast:

784b879638 tests/boot_linux_console: Add a SLOW test booting Ubuntu on OrangePi PC
This test boots Ubuntu Bionic on a OrangePi PC board.

As it requires 1GB of storage, and is slow, this test is disabled
on automatic CI testing.

It is useful for workstation testing. Currently Avocado timeouts too
quickly, so we can't run userland commands.

The kernel image and DeviceTree blob are built by the Armbian
project (based on Debian):
https://www.armbian.com/orange-pi-pc/

The Ubuntu image is downloaded from:
https://dl.armbian.com/orangepipc/Bionic_current

  make: *** [/tmp/qemu-test/src/tests/Makefile.include:632: check-qtest-x86_64] Error 1
  make: *** Waiting for unfinished jobs....

It's not clear why this is happening (perhaps a recently revealed
race condition or a change in the patchew build environment?).

For the moment, disable this test so that patchew test runs are
useful and don't email the list with spurious failure mails.

6a5f6403a1 iotests: Add iothread cases to 155
This patch adds test cases for attaching the backing chain to a mirror
job target right before finalising the job, where the image is in a
non-mainloop AioContext (i.e. the backing chain needs to be moved to the
AioContext of the mirror target).

This requires switching the test case from virtio-blk to virtio-scsi
because virtio-blk only actually starts using the iothreads when the
guest driver initialises the device (which never happens in a test case
without a guest OS). virtio-scsi always keeps its block nodes in the
AioContext of the the requested iothread without guest interaction.

8bdee9f10e iotests: Test mirror with temporarily disabled target backing file
The newly tested scenario is a common live storage migration scenario:
The target node is opened without a backing file so that the active
layer is mirrored while its backing chain can be copied in the
background.

The backing chain should be attached to the mirror target node when
finalising the job, just before switching the users of the source node
to the new copy (at which point the mirror job still has a reference to
the node). drive-mirror did this automatically, but with blockdev-mirror
this is the job of the QMP client.

This patch adds test cases for two ways to achieve the desired result,

d29d3d1f80 block: Relax restrictions for blockdev-snapshot
blockdev-snapshot returned an error if the overlay was already in use,
which it defined as having any BlockBackend parent. This is in fact both
too strict (some parents can tolerate the change of visible data caused
by attaching a backing file) and too loose (some non-BlockBackend
parents may not be happy with it).

One important use case that is prevented by the too strict check is live
storage migration with blockdev-mirror. Here, the target node is
usually opened without a backing file so that the active layer is
mirrored while its backing chain can be copied in the background.

The backing chain should be attached to the mirror target node when
finalising the job, just before switching the users of the source node
to the new copy (at which point the mirror job still has a reference to
the node). drive-mirror did this automatically, but with blockdev-mirror
this is the job of the QMP client, so it needs a way to do this.

blockdev-snapshot is the obvious way, so this patch makes it work in
this scenario. The new condition is that no parent uses CONSISTENT_READ
permissions. This will ensure that the operation will still be blocked
when the node is attached to the guest device, so blockdev-snapshot
remains safe.

(For the sake of completeness, x-blockdev-reopen can be used to achieve
the same, however it is a big hammer, performs the graph change
completely unchecked and is still experimental. So even with the option
of using x-blockdev-reopen, there are reasons why blockdev-snapshot
should be able to perform this operation.)

ISA and sysbus TPM-TIS devices will share their tests. Only
the main() will change (instantiation option is different).
Also the base address of the TPM-TIS device is going to be
different. on x86 it is located at 0xFED40000 while on ARM
it can be located at any location, discovered through the
device tree description.

So we put shared test functions in a new object module.
Each test needs to set tpm_tis_base_addr global variable.

Also take benefit of this move to fix "block comments using
