a5ba86d423 tests/acceptance: allow console interaction with specific VMs
Console interaction in avocado scripts was possible only with single
default VM.

2c9120a223 tests/acceptance/migration.py: Wait for both sides
When the source finishes migration the destination will still be
receiving the data sent by the source, so it might not have quite
finished yet, so won't quite have reached 'completed'.
This lead to occasional asserts in the next few checks.

After the source has finished, check the destination as well.
(We can't just switch to checking the destination, because it doesn't
give a status until it has started receiving the migration).

5d72c68b49 qcow2: Expose bitmaps' size during measure
It's useful to know how much space can be occupied by qcow2 persistent
bitmaps, even though such metadata is unrelated to the guest-visible
data.  Report this value as an additional QMP field, present when
measuring an existing image and output format that both support
bitmaps.  Update iotest 178 and 190 to updated output, as well as new
coverage in 190 demonstrating non-zero values made possible with the
recently-added qemu-img bitmap command (see 3b51ab4b).

The new 'bitmaps size:' field is displayed automatically as part of
'qemu-img measure' any time it is present in QMP (that is, any time
both the source image being measured and destination format support
bitmaps, even if the measurement is 0 because there are no bitmaps
present).  If the field is absent, it means that no bitmaps can be
copied (source, destination, or both lack bitmaps, including when
measuring based on size rather than on a source image).  This behavior
is compatible with an upcoming patch adding 'qemu-img convert
--bitmaps': that command will fail in the same situations where this
patch omits the field.

The addition of a new field demonstrates why we should always
zero-initialize qapi C structs; while the qcow2 driver still fully
populates all fields, the raw and crypto drivers had to be tweaked to
avoid uninitialized data.

Consideration was also given towards having a 'qemu-img measure
--bitmaps' which errors out when bitmaps are not possible, and
otherwise sums the bitmaps into the existing allocation totals rather
than displaying as a separate field, as a potential convenience
factor.  But this was ultimately decided to be more complexity than
necessary when the QMP interface was sufficient enough with bitmaps
remaining a separate field.

b1b30ff4df iotests/030: Reduce run time by unthrottling job earlier
test_overlapping_3() throttles its active commit job so it can be sure
the job is still busy when it checks that you can't start a conflicting
streaming job.

However, it only sets the commit job back to full speed when it is
ready, which takes a few seconds while it's throttled. We can already
reset the limit after having checked that block-stream returns an error
and save these seconds.

69dca43d6b block: Use bdrv_default_perms()
bdrv_default_perms() can decide which permission profile to use based on
the BdrvChildRole, so block drivers do not need to select it explicitly.

The blkverify driver now no longer shares the WRITE permission for the
image to verify.  We thus have to adjust two places in
test-block-iothread not to take it.  (Note that in theory, blkverify
should behave like quorum in this regard and share neither WRITE nor
RESIZE for both of its children.  In practice, it does not really
matter, because blkverify is used only for debugging, so we might as
well keep its permissions rather liberal.)

ffa41a62d0 iotests/109: Don't mirror with mismatched size
This patch makes the raw image the same size as the file in a different
format that is mirrored as raw to it to avoid errors when mirror starts
to enforce that source and target are the same size.

We check only that the first 512 bytes are zeroed (instead of 64k)
because some image formats create image files that are smaller than 64k,
so trying to read 64k would result in I/O errors. Apart from this, 512
is more appropriate anyway because the raw format driver protects
specifically the first 512 bytes.

9ecaf5ccec softfloat: fix floatx80 pseudo-denormal round to integer
The softfloat function floatx80_round_to_int incorrectly handles the
case of a pseudo-denormal where only the high bit of the significand
is set, ignoring that bit (treating the number as an exact zero)
rather than treating the number as an alternative representation of
+/- 2^-16382 (which may round to +/- 1 depending on the rounding mode)
as hardware does.  Fix this check (simplifying the code in the
process).

Conversions between IEEE floating-point formats should convert

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.

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.

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()
  instead.

* Have qos_test.c convert from QObject to the QAPI 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 of this commit, it is now confused:

  <1:3000> at 0x00000000 irq 0
  ...

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:
