The first step to debug a thing is to know what created the thing in
the first place. Add some prefixes so random tmpdir's have something
grep in the code.

If expected_args is 0, qtest frees the argument vector and then returns it
nevertheless. Coverity complains; in practice this is not an issue because
expected_args == 0 means that the caller is not interested in the argument
vector, but it would be a potential problem if somebody wanted to add
commands with optional arguments to qtest.

In qobject_type(), NULL is returned when the 'QObject' returned from parse_value() is not of QString type,
and this 'QObject' memory will leaked.
So we need to first cache the 'QObject' returned from parse_value(), and finally
free 'QObject' memory at the end of the function.
Also, we add a testcast about invalid dict key.
The memleak stack is as follows:
Direct leak of 32 byte(s) in 1 object(s) allocated from:

LLVM's linker, LLD, supports the keyword "INSERT AFTER", starting with
version 11.
However, when multiple sections are defined in the same "INSERT AFTER",
they are added in a reversed order, compared to BFD's LD.
This patch makes fork_fuzz.ld generic enough to work with both linkers.
Each section now has its own "INSERT AFTER" keyword, so proper ordering is
defined between the sections added.

To repeat the rationale from the deprecation note:

- the Linux kernel dropped support for it 10 years ago

Type checks in wait_migration() fail because of the unexpected optional
return type:
iotests.py:750: error: Value of type variable "Msg" of "log" cannot be "Optional[Dict[str, Any]]"

In ahci_exec() we attempt to permit the caller to pass a NULL pointer
for opts_in (in which case we use a default set of options). However
although we check for NULL when setting up the opts variable at the
top of the function, we unconditionally dereference opts_in at the
end of the function as part of freeing the opts->buffer.
Switch to checking whether the final buffer is the same as the
buffer we started with, instead of assuming the value we started
with is always opts_in->buffer.
At the moment all the callers pass a non-NULL opts argument, so
we never saw any crashes in practice.

The abstract socket namespace is a non-portable Linux extension. An
attempt to use it elsewhere should fail with ENOENT (the abstract
address looks like a "" pathname, which does not resolve). We report
this failure like
Failed to connect socket abc: No such file or directory
Tolerable, although ENOTSUP would be better.
However, introspection lies: it has @abstract regardless of host
support. Easy enough to fix: since Linux provides them since 2.2,
'if': 'defined(CONFIG_LINUX)' should do.
The above failure becomes
Parameter 'backend.data.addr.data.abstract' is unexpected

An optional bool member of a QAPI struct can be false, true, or absent.
The previous commit demonstrated that socket_listen() and
socket_connect() are broken for absent @tight, and indeed QMP chardev-
add also defaults absent member @tight to false instead of true.
In C, QAPI members are represented by two fields, has_MEMBER and MEMBER.
We have:
has_MEMBER MEMBER
false true false
true true true
absent false false/ignore
When has_MEMBER is false, MEMBER should be set to false on write, and
ignored on read.
For QMP, the QAPI visitors handle absent @tight by setting both
@has_tight and @tight to false. unix_listen_saddr() and
unix_connect_saddr() however use @tight only, disregarding @has_tight.
This is wrong and means that absent @tight defaults to false whereas it
should default to true.
The same is true for @has_abstract, though @abstract defaults to
false and therefore has the same behavior for all of QMP, HMP and CLI.
Fix unix_listen_saddr() and unix_connect_saddr() to check
@has_abstract/@has_tight, and to default absent @tight to true.
However, this is only half of the story. HMP chardev-add and CLI
-chardev so far correctly defaulted @tight to true, but defaults to
false again with the above fix for HMP and CLI. In fact, the "tight"
and "abstract" options now break completely.
Digging deeper, we find that qemu_chr_parse_socket() also ignores
@has_tight, leaving it false when it sets @tight. That is also wrong,
but the two wrongs cancelled out. Fix qemu_chr_parse_socket() to set
@has_tight and @has_abstract; writing testcases for HMP and CLI is left
for another day.

former is listening when the latter tries to connect. Review fail.
Risks spurious test failure, say when a heavily loaded machine doesn't
schedule the first thread quickly enough. It's also slow.
Listen and accept in the main thread, and start the connect thread in
between. Look ma, no sleep! Run time drops from 2s wall clock to a

This test invokes several shell scripts to create a random directory
tree full of submounts, and then check in the VM whether every submount
has its own ID and the structure looks as expected.
(Note that the test scripts must be non-executable, so Avocado will not
try to execute them as if they were tests on their own, too.)
Because at this commit's date it is unlikely that the Linux kernel on
the image provided by boot_linux.py supports submounts in virtio-fs, the
test will be cancelled if no custom Linux binary is provided through the
vmlinuz parameter. (The on-image kernel can be used by providing an
empty string via vmlinuz=.)
So, invoking the test can be done as follows:
$ avocado run \
tests/acceptance/virtiofs_submounts.py \
-p vmlinuz=/path/to/linux/build/arch/x86/boot/bzImage
This test requires root privileges (through passwordless sudo -n),
because at this point, virtiofsd requires them. (If you have a
timestamp_timeout period for sudoers (e.g. the default of 5 min), you
can provide this by executing something like "sudo true" before invoking
Avocado.)

(Failures have been observed on all 4 of the randomness tests,
not just first_byte_runs.)
It's not clear why these tests are failing like this, but intermittent
failures make CI and merge testing awkward, so disable running them

running the test suite, until we work out the cause.

Split out walking a directory path to a separate new utility function
do_walk() and use that function in do_mkdir().
The code difference saved this way is not much, but we'll use that new
do_walk() function in the upcoming patches, so it will avoid quite
some code duplication after all.

Use mkdtemp() to generate a unique directory for the 9p 'local' tests.
This fixes occasional 9p test failures when running 'make check -jN' if
QEMU was compiled for multiple target architectures, because the individual
architecture's test suites would run in parallel and interfere with each
other's data as the test directory was previously hard coded and hence the
same directory was used by all of them simultaniously.
This also requires a change how the test directory is created and deleted:
As the test path is now randomized and virtio_9p_register_nodes() being
called in a somewhat undeterministic way, that's no longer an appropriate
place to create and remove the test directory. Use a constructor and
destructor function for creating and removing the test directory instead.
Unfortunately libqos currently does not support setup/teardown callbacks
to handle this more cleanly.
The constructor functions needs to be in virtio-9p-test.c, not in
virtio-9p.c, because in the latter location it would cause all apps that
link to libqos (i.e. entirely unrelated test suites) to create a 9pfs
test directory as well, which would even break other test suites.

Allow the server to expose an additional metacontext to be requested
by savvy clients. qemu-nbd adds a new option -A to expose the
qemu:allocation-depth metacontext through NBD_CMD_BLOCK_STATUS; this
can also be set via QMP when using block-export-add.
qemu as client is hacked into viewing the key aspects of this new
context by abusing the already-experimental x-dirty-bitmap option to
collapse all depths greater than 2, which results in a tri-state value
visible in the output of 'qemu-img map --output=json' (yes, that means
x-dirty-bitmap is now a bit of a misnomer, but I didn't feel like
renaming it as it would introduce a needless break of back-compat,
even though we make no compat guarantees with x- members):
unallocated (depth 0) => "zero":false, "data":true
local (depth 1) => "zero":false, "data":false
backing (depth 2+) => "zero":true, "data":true
libnbd as client is probably a nicer way to get at the information
without having to decipher such hacks in qemu as client. ;)

nbd_server_start_unix_socket() includes an implicit nbd_server_stop(),
but we still need an explicit one at the end of the test (where there
follows no next nbd_server_start_unix_socket()), or qemu-nbd will linger
until the test exits.
This will become important when enabling this test to run on FUSE
exports, because then the export (which is the image used by qemu-nbd)
will go away before qemu-nbd exits, which will lead to qemu-nbd
complaining that it cannot flush the bitmaps in the image.

We need to let _img_info emit the format-specific information so we get
the list of bitmaps we want, but we do not need anything but the
bitmaps. So filter out everything that is irrelevant to us. (Ideally,
this would be a generalized function in common.filters that takes a list
of things to keep, but that would require implementing an anti-bitmap
filter, which would be hard, and which we do not need here. So that is
why this function is just a local hack.)
This lets 291 pass with qcow2 options like refcount_bits or data_file
again.

Reporting "Failed to connect socket" is essentially useless for a user
attempting to diagnose failure. It needs to include the target address
details. Similarly when failing to create a socket we should include the
socket family info, so the user understands what particular feature was
missing in their kernel build (IPv6, VSock in particular).

If a BDS gets deleted during blk_drain_all(), it might miss a
call to bdrv_do_drained_end(). This means missing a call to
aio_enable_external() and the AIO context remains disabled for
ever. This can cause a device to become irresponsive and to
disrupt the guest execution, ie. hang, loop forever or worse.
This scenario is quite easy to encounter with virtio-scsi
on POWER when punching multiple blockdev-create QMP commands
while the guest is booting and it is still running the SLOF
firmware. This happens because SLOF disables/re-enables PCI
devices multiple times via IO/MEM/MASTER bits of PCI_COMMAND
register after the initial probe/feature negotiation, as it
tends to work with a single device at a time at various stages
like probing and running block/network bootloaders without
doing a full reset in-between. This naturally generates many
dataplane stops and starts, and thus many drain sections that
can race with blockdev_create_run(). In the end, SLOF bails
out.
It is somehow reproducible on x86 but it requires to generate
articial dataplane start/stop activity with stop/cont QMP
commands. In this case, seabios ends up looping for ever,
waiting for the virtio-scsi device to send a response to
a command it never received.
Add a helper that pairs all previously called bdrv_do_drained_begin()
with a bdrv_do_drained_end() and call it from bdrv_close().
While at it, update the "/bdrv-drain/graph-change/drain_all"
test in test-bdrv-drain so that it can catch the issue.

The NPCM7xx chips have multiple GPIO controllers that are mostly
identical except for some minor differences like the reset values of
some registers. Each controller controls up to 32 pins.
Each individual pin is modeled as a pair of unnamed GPIOs -- one for
emitting the actual pin state, and one for driving the pin externally.
Like the nRF51 GPIO controller, a gpio level may be negative, which
means the pin is not driven, or floating.

The RNG module returns a byte of randomness when the Data Valid bit is
set.
This implementation ignores the prescaler setting, and loads a new value
into RNGD every time RNGCS is read while the RNG is enabled and random
data is available.
A qtest featuring some simple randomness tests is included.

The watchdog is part of NPCM7XX's timer module. Its behavior is
controlled by the WTCR register in the timer.
When enabled, the watchdog issues an interrupt signal after a pre-set
amount of cycles, and issues a reset signal shortly after that.

Currently the test randomly fails if you are using a shared machine
due to contention on the well known port 1234. We can ameliorate this
a bit by picking a random non-ephemeral port although it doesn't
totally avoid the problem. While we could use a totally unique socket
address for debugging it is fiddly to probe for gdb support. While gdb
socket debugging is not yet ubiquitous this a sub-optimal but workable
option.

This test invokes several shell scripts to create a random directory
tree full of submounts, and then check in the VM whether every submount
has its own ID and the structure looks as expected.
(Note that the test scripts must be non-executable, so Avocado will not
try to execute them as if they were tests on their own, too.)
Because at this commit's date it is unlikely that the Linux kernel on
the image provided by boot_linux.py supports submounts in virtio-fs, the
test will be cancelled if no custom Linux binary is provided through the
vmlinuz parameter. (The on-image kernel can be used by providing an
empty string via vmlinuz=.)
So, invoking the test can be done as follows:
$ avocado run \
tests/acceptance/virtiofs_submounts.py \
-p vmlinuz=/path/to/linux/build/arch/x86/boot/bzImage
This test requires root privileges (through passwordless sudo -n),
because at this point, virtiofsd requires them. (If you have a
timestamp_timeout period for sudoers (e.g. the default of 5 min), you
can provide this by executing something like "sudo true" before invoking
Avocado.)

This is a generic fuzzer designed to fuzz a virtual device's
MemoryRegions, as long as they exist within the Memory or Port IO (if it
exists) AddressSpaces. The fuzzer's input is interpreted into a sequence
of qtest commands (outb, readw, etc). The interpreted commands are
separated by a magic seaparator, which should be easy for the fuzzer to
guess. Without ASan, the separator can be specified as a "dictionary
value" using the -dict argument (see libFuzzer documentation).

This test won't work if qemu was compiled without CONFIG_NPCM7XX, as
pointed out by Thomas Huth on a different patch.

The qtests can be run directly by specifying the QEMU binary with the
QTEST_QEMU_BINARY environment variable, for example:
$ QTEST_QEMU_BINARY=x86_64-softmmu/qemu-system-x86_64 tests/qtest/test-hmp
However, if you specify a binary without a path, for example with
QTEST_QEMU_BINARY=qemu-system-x86_64 if the QEMU binary is in your
$PATH, then the test currently simply crashes.
Let's try a little bit smarter here by looking for the final '-'
instead of the slash.

Allow vu_message_read to be replaced by one which will make use of the
QIOChannel functions. Thus reading vhost-user message won't stall the
guest. For slave channel, we still use the default vu_message_read.

this fixes non-TCG builds broken recently by replay reverse debugging.
Stub the needed functions in stub/, splitting roughly between functions
needed only by system emulation, by system emulation and tools,
and by everyone. This includes duplicating some code in replay/, and
puts the logic for non-replay related events in the replay/ module (+
the stubs), so this should be revisited in the future.
Surprisingly, only _one_ qtest was affected by this, ide-test.c, which
resulted in a buzz as the bh events were never delivered, and the bh
never executed.
Many other subsystems _should_ have been affected.
This fixes the immediate issue, however a better way to group replay
functionality to TCG-only code could be developed in the long term.

the tests assume TCG is available, thus breaking
for TCG-only tests, where only the TCG accelerator option
is passed to the QEMU binary.

This test exercises the various modes of the npcm7xx timer. In
particular, it triggers the bug found by the fuzzer, as reported here:
https://lists.gnu.org/archive/html/qemu-devel/2020-09/msg02992.html
It also found several other bugs, especially related to interrupt
handling.
The test exercises all the timers in all the timer modules, which
expands to 180 test cases in total.

mypy wants to ensure there's consistency between the kwargs arguments
types and any unspecified keyword arguments. In this case, conv_keys is
a bool, but the remaining keys are Any type. Mypy (correctly) infers the
**kwargs type to be **Dict[str, str], which is not compatible with
conv_keys: bool.
Because QMP typing is a little fraught right now anyway, re-type kwargs
to Dict[str, Any] which has the benefit of silencing this check right
now.
A future re-design might type these more aggressively, but this will
give us a baseline to work from with minimal disruption.

This test case uses the 9pfs 'local' driver to create a directory
and then checks if the expected directory was actually created
(as real directory) on host side.
This patch introduces a custom split() implementation, because
the test code requires non empty array elements as result. For
that reason g_strsplit() would not be a good alternative, as
it would require additional filter code for reshuffling the
array, and the resulting code would be even more complex than
this split() function.
