84e4a27fed tests/functional: Set up logging
Create log files for each test separately, one file that contains
the basic logging and one that contains the console output.

fa32a63432 tests/functional: Add base classes for the upcoming pytest-based tests
The files are mostly a copy of the tests/avocado/avocado_qemu/__init__.py
file with some adjustments to get rid of the Avocado dependencies (i.e.
we also have to drop the LinuxSSHMixIn and LinuxTest for now).

The emulator binary and build directory are now passed via
environment variables that will be set via meson.build later.

5ec1eec110 python: Install pycotap in our venv if necessary
The upcoming functional tests will require pycotap for providing
TAP output from the python-based tests. Since we want to be able
to run some of the tests offline by default, too, let's install
it along with meson in our venv if necessary (it's size is only
5 kB, so adding the wheel here should not really be a problem).

The wheel file has been obtained with:

 pip download --only-binary :all: --dest . --no-cache pycotap

b5347978a9 tests/avocado/boot_linux_console: Remove the s390x subtest
We've got a much more sophisticated, Fedora-based test for s390x
("test_s390x_fedora" in another file) already, so the test in
boot_linux_console.py seems to be rather a waste of precious test
cycles. Thus move the command line check and delete the s390x
test in boot_linux_console.py.

657136c653 Bump avocado to 103.0
This bumps Avocado to latest the LTS release.

An LTS release is one that can receive bugfixes and guarantees
stability for a much longer period and has incremental minor releases
made.

Even though the 103.0 LTS release is pretty a rewrite of Avocado when
compared to 88.1, the behavior of all existing tests under
tests/avocado has been extensively tested no regression in behavior
was found.

To keep behavior of jobs as close as possible with previous version,
this version bump keeps the execution serial (maximum of one task at a
time being run).

43e0d14ee0 docs/sphinx: fix extra stuff in TOC after freeform QMP sections
Freeform sections with titles are currently generating a TOC entry for
the first paragraph in the section after the header, which is not what
we want.

(Easiest to observe directly in the QMP reference manual's
"Introduction" section.)

When freeform sections are parsed, we create both a section header *and*
an empty, title-less section. This causes some problems with sphinx's
post-parse tree transforms, see also 2664f317 - this is a similar issue:
Sphinx doesn't like section-less titles and it also doesn't like
title-less sections.

Modify qapidoc.py to parse text directly into the preceding section
title as child nodes, eliminating the section duplication. This removes
the extra text from the TOC.

Only very, very lightly tested: "it looks right at a glance" ™️. I am
still in the process of rewriting qapidoc, so I didn't give it much
deeper thought.

3874f5f73c nbd/server: CVE-2024-7409: Avoid use-after-free when closing server
Commit 3e7ef738 plugged the use-after-free of the global nbd_server
object, but overlooked a use-after-free of nbd_server->listener.
Although this race is harder to hit, notice that our shutdown path
first drops the reference count of nbd_server->listener, then triggers
actions that can result in a pending client reaching the
nbd_blockdev_client_closed() callback, which in turn calls
qio_net_listener_set_client_func on a potentially stale object.

If we know we don't want any more clients to connect, and have already
told the listener socket to shut down, then we should not be trying to
update the listener socket's associated function.

Reproducer:

8f97deb99c .gitlab-ci.d/windows.yml: Disable the qtests in the MSYS2 job
The qtests are broken since a while in the MSYS2 job in the gitlab-CI,
likely due to some changes in the MSYS2 environment. So far nobody has
neither a clue what's going wrong here, nor an idea how to fix this
(in fact most QEMU developers even don't have a Windows environment
available for properly analyzing this problem), so we should disable the
qtests here for the time being to get at least test coverage again
for the remaining tests that are run here.

Since we already get compile-test coverage for the system emulation
in the cross-win64-system job, and since the MSYS2 job is one of the
longest running jobs in our CI (it takes more than 1 hour to complete),
let's seize the opportunity and also cut the run time by disabling
the system emulation completely here, including the libraries that
are only useful for system emulation. In case somebody ever figures
out the failure of the qtests on MSYS2, we can revert this patch
to get everything back.

eb9ca730da gitlab-ci: Replace build_script -> step_script in Cirrus jobs
Long due upgrade, see [1]:

  In GitLab Runner 13.2 a translation for step_script to
  build_script was added to the custom executor. In 14.0
  the build_script stage will be replaced with step_script.

We are using GitLab 17 [2]!

This removes the following warning:

  WARNING: Starting with version 17.0 the 'build_script'
  stage will be replaced with 'step_script':

d53bb908b5 system/vl.c: Print machine name, not "(null)", for unknown machine types
In commit 412d294ffd we tried to improve the error message printed when
the machine type is unknown, but we used the wrong variable, resulting in:

$ ./build/x86/qemu-system-aarch64 -M bang
qemu-system-aarch64: unsupported machine type: "(null)"
Use -machine help to list supported machines

Use the right variable, so we produce more helpful output:

$ ./build/x86/qemu-system-aarch64 -M bang
qemu-system-aarch64: unsupported machine type: "bang"
Use -machine help to list supported machines

Note that we must move the qdict_del() to below the error_setg(),
because machine_type points into the value of that qdict entry,
and deleting it will make the pointer invalid.

ded1db48c9 target/i386: Fix tss access size in switch_tss_ra
The two limit_max variables represent size - 1, just like the
encoding in the GDT, thus the 'old' access was off by one.
Access the minimal size of the new tss: the complete tss contains
the iopb, which may be a larger block than the access api expects,
and irrelevant because the iopb is not accessed during the
switch itself.

In multifd_recv_setup() we allocate (among other things)
 * a MultiFDRecvData struct to multifd_recv_state::data
 * a MultiFDRecvData struct to each multfd_recv_state->params[i].data

(Then during execution we might swap these pointers around.)

But in multifd_recv_cleanup() we free multifd_recv_state->data
in multifd_recv_cleanup_state() but we don't ever free the
multifd_recv_state->params[i].data. This results in a memory

a8e63ff289 virtio-pci: Fix the use of an uninitialized irqfd
The crash was reported in MAC OS and NixOS, here is the link for this bug
https://gitlab.com/qemu-project/qemu/-/issues/2334
https://gitlab.com/qemu-project/qemu/-/issues/2321

In this bug, they are using the virtio_input device. The guest notifier was
not supported for this device, The function virtio_pci_set_guest_notifiers()
was not called, and the vector_irqfd was not initialized.

So the fix is adding the check for vector_irqfd in virtio_pci_get_notifier()

The function virtio_pci_get_notifier() can be used in various devices.
It could also be called when VIRTIO_CONFIG_S_DRIVER_OK is not set. In this situation,
the vector_irqfd being NULL is acceptable. We can allow the device continue to boot

If the vector_irqfd still hasn't been initialized after VIRTIO_CONFIG_S_DRIVER_OK
is set, it means that the function set_guest_notifiers was not called before the
driver started. This indicates that the device is not using the notifier.
At this point, we will let the check fail.

This fix is verified in vyatta,MacOS,NixOS,fedora system.

7d14471a12 hw/audio/virtio-snd: fix invalid param check
Commit 9b6083465f ("virtio-snd: check for invalid param shift
operands") tries to prevent invalid parameters specified by the
guest. However, the code is not correct.

Change the code so that the parameters format and rate, which are
a bit numbers, are compared with the bit size of the data type.

87e012f29f crypto/tlscredspsk: Free username on finalize
When the creds->username property is set we allocate memory
for it in qcrypto_tls_creds_psk_prop_set_username(), but
we never free this when the QCryptoTLSCredsPSK is destroyed.
Free the memory in finalize.

This fixes a LeakSanitizer complaint in migration-test:

702cbdc46b hw/i386/pc: Ensure vmport prerequisites are fulfilled
Since commit 4ccd5fe22f ('pc: add option
to disable PS/2 mouse/keyboard'), the vmport will not be created unless
the i8042 PS/2 controller is enabled. To avoid confusion, let's fail if
vmport was explicitly requested, but the i8042 controller is disabled.
This also changes the behavior of vmport=auto to take i8042 controller
availability into account.

c911f875f8 hw/i386/pc: Unify vmport=auto handling
The code which translates vmport=auto to on/off is currently separate
for each PC machine variant, while being functionally equivalent.
This moves the translation into a shared initialization function, while
also tightening the enum assertion.

4a85f23157 tests/avocado: exec_command should not consume console output
_console_interaction reads data from the console even when there is only
an input string to send, and no output data to wait on. This can cause
lines to be missed by wait_for_console_pattern calls that follows an
exec_command. Fix this by not reading the console if there is no pattern
to wait for.

This solves occasional hangs in ppc_hv_tests.py, usually when run on KVM
hosts that are fast enough to output important lines quickly enough to be
consumed by exec_command, so they get missed by subsequent wait for
pattern calls.
