When a write request is converted into a write zeroes request by the

The BDRV_REQ_REGISTERED_BUF flag doesn't make sense without an I/O

qcow2: Fix theoretical corruption in store_bitmap() error path
In order to write the bitmap table to the image file, it is converted to
big endian. If the write fails, it is passed to clear_bitmap_table() to
free all of the clusters it had allocated before. However, if we don't
convert it back to native endianness first, we'll free things at a wrong
offset.
In practical terms, the offsets will be so high that we won't actually
free any allocated clusters, but just run into an error, but in theory
this can cause image corruption.

acpi: cpuhp: fix guest-visible maximum access size to the legacy reg block
The modern ACPI CPU hotplug interface was introduced in the following
series (aa1dd39ca307..679dd1a957df), released in v2.7.0:
1 abd49bc2ed2f docs: update ACPI CPU hotplug spec with new protocol
2 16bcab97eb9f pc: piix4/ich9: add 'cpu-hotplug-legacy' property
3 5e1b5d93887b acpi: cpuhp: add CPU devices AML with _STA method
4 ac35f13ba8f8 pc: acpi: introduce AcpiDeviceIfClass.madt_cpu hook
5 d2238cb6781d acpi: cpuhp: implement hot-add parts of CPU hotplug
interface
6 8872c25a26cc acpi: cpuhp: implement hot-remove parts of CPU hotplug
interface
7 76623d00ae57 acpi: cpuhp: add cpu._OST handling
8 679dd1a957df pc: use new CPU hotplug interface since 2.7 machine type
Before patch#1, "docs/specs/acpi_cpu_hotplug.txt" only specified 1-byte
accesses for the hotplug register block. Patch#1 preserved the same
restriction for the legacy register block, but:
- it specified DWORD accesses for some of the modern registers,
- in particular, the switch from the legacy block to the modern block
would require a DWORD write to the *legacy* block.
The latter functionality was then implemented in cpu_status_write()
[hw/acpi/cpu_hotplug.c], in patch#8.
Unfortunately, all DWORD accesses depended on a dormant bug: the one
introduced in earlier commit a014ed07bd5a ("memory: accept mismatching
sizes in memory_region_access_valid", 2013-05-29); first released in
v1.6.0. Due to commit a014ed07bd5a, the DWORD accesses to the *legacy*
CPU hotplug register block would work in spite of the above series *not*
relaxing "valid.max_access_size = 1" in "hw/acpi/cpu_hotplug.c":
Later, in commits e6d0c3ce6895 ("acpi: cpuhp: introduce 'Command data 2'
field", 2020-01-22) and ae340aa3d256 ("acpi: cpuhp: spec: add typical
usecases", 2020-01-22), first released in v5.0.0, the modern CPU hotplug
interface (including the documentation) was extended with another DWORD
*read* access, namely to the "Command data 2" register, which would be
important for the guest to confirm whether it managed to switch the
register block from legacy to modern.
This functionality too silently depended on the bug from commit a014ed07bd5a.
In commit 5d971f9e6725 ('memory: Revert "memory: accept mismatching sizes
in memory_region_access_valid"', 2020-06-26), first released in v5.1.0,
the bug from commit a014ed07bd5a was fixed (the commit was reverted).
That swiftly exposed the bug in "AcpiCpuHotplug_ops", still present from
the v2.7.0 series quoted at the top -- namely the fact that
"valid.max_access_size = 1" didn't match what the guest was supposed to
do, according to the spec ("docs/specs/acpi_cpu_hotplug.txt").
The symptom is that the "modern interface negotiation protocol"
described in commit ae340aa3d256:
> + Use following steps to detect and enable modern CPU hotplug interface:
> + 1. Store 0x0 to the 'CPU selector' register,
> + attempting to switch to modern mode
> + 2. Store 0x0 to the 'CPU selector' register,
> + to ensure valid selector value
> + 3. Store 0x0 to the 'Command field' register,
> + 4. Read the 'Command data 2' register.
> + If read value is 0x0, the modern interface is enabled.
> + Otherwise legacy or no CPU hotplug interface available
falls apart for the guest: steps 1 and 2 are lost, because they are DWORD
writes; so no switching happens. Step 3 (a single-byte write) is not
lost, but it has no effect; see the condition in cpu_status_write() in
patch#8. And step 4 *misleads* the guest into thinking that the switch
worked: the DWORD read is lost again -- it returns zero to the guest
without ever reaching the device model, so the guest never learns the
switch didn't work.
This means that guest behavior centered on the "Command data 2" register
worked *only* in the v5.0.0 release; it got effectively regressed in
v5.1.0.
To make things *even more* complicated, the breakage was (and remains, as
of today) visible with TCG acceleration only. Commit 5d971f9e6725 makes
no difference with KVM acceleration -- the DWORD accesses still work,
despite "valid.max_access_size = 1".
As commit 5d971f9e6725 suggests, fix the problem by raising
"valid.max_access_size" to 4 -- the spec now clearly instructs the guest
to perform DWORD accesses to the legacy register block too, for enabling
(and verifying!) the modern block. In order to keep compatibility for the
device model implementation though, set "impl.max_access_size = 1", so
that wide accesses be split before they reach the legacy read/write
handlers, like they always have been on KVM, and like they were on TCG
before 5d971f9e6725 (v5.1.0).
Tested with:
- OVMF IA32 + qemu-system-i386, CPU hotplug/hot-unplug with SMM,
intermixed with ACPI S3 suspend/resume, using KVM accel
(regression-test);
- OVMF IA32X64 + qemu-system-x86_64, CPU hotplug/hot-unplug with SMM,
intermixed with ACPI S3 suspend/resume, using KVM accel
(regression-test);
- OVMF IA32 + qemu-system-i386, SMM enabled, using TCG accel; verified the
register block switch and the present/possible CPU counting through the
modern hotplug interface, during OVMF boot (bugfix test);
- I do not have any testcase (guest payload) for regression-testing CPU
hotplug through the *legacy* CPU hotplug register block.

target/s390x/tcg: Fix and improve the SACF instruction
The SET ADDRESS SPACE CONTROL FAST instruction is not privileged, it can be
used from problem space, too. Just the switching to the home address space
is privileged and should still generate a privilege exception. This bug is
e.g. causing programs like Java that use the "getcpu" vdso kernel function
to crash (see https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=990417#26 ).
While we're at it, also check if DAT is not enabled. In that case the
instruction is supposed to generate a special operation exception.

The data->clientcert and data->clientkey pointers can indeed be unset
in some tests, so we have to check them before calling unlink() with
those.
While we're at it, I also noticed that the code is only freeing
some but not all of the allocated strings in this function, and
indeed, valgrind is also complaining about memory leaks here.
So let's call g_free() on all allocated strings to avoid leaking
memory here.

Secondly, and worse, because the request is queued up for posting to the

vhost: enable vrings in vhost_dev_start() for vhost-user devices
Commit 02b61f38d3 ("hw/virtio: incorporate backend features in features")
properly negotiates VHOST_USER_F_PROTOCOL_FEATURES with the vhost-user
backend, but we forgot to enable vrings as specified in
docs/interop/vhost-user.rst:
If ``VHOST_USER_F_PROTOCOL_FEATURES`` has not been negotiated, the
ring starts directly in the enabled state.
If ``VHOST_USER_F_PROTOCOL_FEATURES`` has been negotiated, the ring is
initialized in a disabled state and is enabled by
``VHOST_USER_SET_VRING_ENABLE`` with parameter 1.
Some vhost-user front-ends already did this by calling
vhost_ops.vhost_set_vring_enable() directly:
- backends/cryptodev-vhost.c
- hw/net/virtio-net.c
- hw/virtio/vhost-user-gpio.c
But most didn't do that, so we would leave the vrings disabled and some
backends would not work. We observed this issue with the rust version of
virtiofsd [1], which uses the event loop [2] provided by the
vhost-user-backend crate where requests are not processed if vring is
not enabled.
Let's fix this issue by enabling the vrings in vhost_dev_start() for
vhost-user front-ends that don't already do this directly. Same thing
also in vhost_dev_stop() where we disable vrings.

1. qemu_cleanup() closes all drives, setting blk->root to NULL
2. qemu_cleanup() calls user_creatable_cleanup(), which results in a RAM

3. blk_unregister_buf() is called by virtio-blk's BlockRamRegistrar

hw/audio/intel-hda: don't reset codecs twice
Currently the intel-hda device has a reset method which manually
resets all the codecs by calling device_legacy_reset() on them. This
means they get reset twice, once because child devices on a qbus get
reset before the parent device's reset method is called, and then
again because we're manually resetting them.
Drop the manual reset call, and ensure that codecs are still reset
when the guest does a reset via ICH6_GCTL_RESET by using
device_cold_reset() (which resets all the devices on the qbus as well
as the device itself) instead of a direct call to the reset function.
This is a slight ordering change because the (only) codec reset now
happens before the controller registers etc are reset, rather than
once before and then once after, but the codec reset function
hda_audio_reset() doesn't care.
This lets us drop a use of device_legacy_reset(), which is

ui/gtk: prevent ui lock up when dpy_gl_update called again before current draw event occurs
A warning, "qemu: warning: console: no gl-unblock within" followed by
guest scanout lockup can happen if dpy_gl_update is called in a row
and the second call is made before gd_draw_event scheduled by the first
call is taking place. This is because draw call returns without decrementing
gl_block ref count if the dmabuf was already submitted as shown below.
(gd_gl_area_draw/gd_egl_draw)
if (dmabuf) {
if (!dmabuf->draw_submitted) {
return;
} else {
dmabuf->draw_submitted = false;
}
}
So it should not schedule any redundant draw event in case draw_submitted is
already set in gd_egl_fluch/gd_gl_area_scanout_flush.

tests/qtest: Decrease the amount of output from the qom-test
The logs in the gitlab-CI have a size constraint, and sometimes
we already hit this limit. The biggest part of the log then seems
to be filled by the qom-test, so we should decrease the size of
the output - which can be done easily by not printing the path
for each property, since the path has already been logged at the
beginning of each node that we handle here.
However, if we omit the path, we should make sure to not recurse
into child nodes in between, so that it is clear to which node
each property belongs. Thus store the children and links in a
temporary list and recurse only at the end of each node, when
all properties have already been printed.

The LPA2 extension implements 52-bit virtual addressing for 4k and 16k
translation granules, and for the former, this means an additional level
of translation is needed. This means we start counting at -1 instead of
0 when doing a walk, and so 'level' is now a signed quantity, and should
be typed as such. So turn it from uint32_t into int32_t.
This avoids a level of -1 getting misinterpreted as being >= 3, and
terminating a page table walk prematurely with a bogus output address.

target/arm: Don't do two-stage lookup if stage 2 is disabled
In get_phys_addr_with_struct(), we call get_phys_addr_twostage() if
the CPU supports EL2. However, we don't check here that stage 2 is
actually enabled. Instead we only check that inside
get_phys_addr_twostage() to skip stage 2 translation. This means
that even if stage 2 is disabled we still tell the stage 1 lookup to
do its page table walks via stage 2.
This works by luck for normal CPU accesses, but it breaks for debug
accesses, which are used by the disassembler and also by semihosting
file reads and writes, because the debug case takes a different code
path inside S1_ptw_translate().
This means that setups that use semihosting for file loads are broken
(a regression since 7.1, introduced in recent ptw refactoring), and
that sometimes disassembly in debug logs reports "unable to read
memory" rather than showing the guest insns.
Fix the bug by hoisting the "is stage 2 enabled?" check up to
get_phys_addr_with_struct(), so that we handle S2 disabled the same
way we do the "no EL2" case, with a simple single stage lookup.

moved ISA bridge AML generation to respective devices and was using
aml_alias() to provide PRQx fields in _SB. scope. However, it turned
out that SeaBIOS was not able to process Alias opcode when parsing DSDT,
resulting in lack of keyboard during boot (SeaBIOS console, grub, FreeDOS).
While fix for SeaBIOS is posted
https://mail.coreboot.org/hyperkitty/list/seabios@seabios.org/thread/RGPL7HESH5U5JRLEO6FP77CZVHZK5J65/
fixed SeaBIOS might not make into QEMU-7.2 in time.
Hence this workaround that puts PRQx back into _SB scope
and gets rid of aliases in ISA bridge description, so
DSDT will be parsable by broken SeaBIOS.
That brings back hardcoded references to ISA bridge
PCI0.S08.P40C/PCI0.SF8.PIRQ
where middle part now is auto generated based on slot it's
plugged in, but it should be fine as bridge initialization
also hardcodes PCI address of the bridge so it can't ever
move. Once QEMU tree has fixed SeaBIOS blob, we should be able
to drop this part and revert back to alias based approach

vhost: mask VIRTIO_F_RING_RESET for vhost and vhost-user devices
Commit 69e1c14aa2 ("virtio: core: vq reset feature negotation support")
enabled VIRTIO_F_RING_RESET by default for all virtio devices.
This feature is not currently emulated by QEMU, so for vhost and
vhost-user devices we need to make sure it is supported by the offloaded
device emulation (in-kernel or in another process).
To do this we need to add VIRTIO_F_RING_RESET to the features bitmap
passed to vhost_get_features(). This way it will be masked if the device
does not support it.
This issue was initially discovered with vhost-vsock and vhost-user-vsock,
and then also tested with vhost-user-rng which confirmed the same issue.
They fail when sending features through VHOST_SET_FEATURES ioctl or
VHOST_USER_SET_FEATURES message, since VIRTIO_F_RING_RESET is negotiated
by the guest (Linux >= v6.0), but not supported by the device.

coverage for that already in the boot_xen.py tests. If we want to
introduce more comprehensive testing we can do it with a custom kernel
and initrd rather than a full distro boot.

tests/avocado: Raise timeout for boot_linux.py:BootLinuxPPC64.test_pseries_tcg
On my machine, a debug build of QEMU takes about 260 seconds to
complete this test, so with the current timeout value of 180 seconds
it always times out. Double the timeout value to 360 so the test
definitely has enough time to complete.

docs/devel: try and improve the language around patch review
It is important that contributors take the review process seriously
and we collaborate in a respectful way while avoiding personal
attacks. Try and make this clear in the language.
