pci: acpi: Windows 'PCI Label Id' bug workaround
Current versions of Windows call _DSM(func=7) regardless
of whether it is supported or not. It leads to NICs having bogus
'PCI Label Id = 0', where none should be set at all.
Also presence of 'PCI Label Id' triggers another Windows bug
on localized versions that leads to hangs. The later bug is fixed
in latest updates for 'Windows Server' but not in consumer
versions of Windows (and there is no plans to fix it
as far as I'm aware).
Given it's easy, implement Microsoft suggested workaround
(return invalid Package) so that affected Windows versions
could boot on QEMU.
This would effectvely remove bogus 'PCI Label Id's on NICs,
but MS teem confirmed that flipping 'PCI Label Id' should not
change 'Network Connection' ennumeration, so it should be safe
for QEMU to change _DSM without any compat code.

hw/usb/hcd-xhci-pci: Use modulo to select MSI vector as per spec
QEMU would crash with a failed assertion if the XHCI controller
attempted to raise the interrupt on an interrupter corresponding
to a MSI vector with a higher index than the highest configured
for the device by the guest driver.
This behaviour is correct on the MSI/PCI side: per PCI 3.0 spec,
devices must ensure they do not send MSI notifications for
vectors beyond the range of those allocated by the system/driver
software. Unlike MSI-X, there is no generic way for handling
aliasing in the case of fewer allocated vectors than requested,
so the specifics are up to device implementors. (Section
6.8.3.4. "Sending Messages")
It turns out the XHCI spec (Implementation Note in section 4.17,
"Interrupters") requires that the host controller signal the MSI
vector with the number computed by taking the interrupter number
modulo the number of enabled MSI vectors.
This change introduces that modulo calculation, fixing the
failed assertion. This makes the device work correctly in MSI mode
with macOS's XHCI driver, which only allocates a single vector.

migration: Fix arrays of pointers in JSON writer
Currently, if an array of pointers contains a NULL pointer, that
pointer will be encoded as '0' in the stream. Since the JSON writer
doesn't define a "pointer" type, that '0' will now be an uint8, which
is different from the original type being pointed to, e.g. struct.
(we're further calling uint8 "nullptr", but that's irrelevant to the
issue)
That mixed-type array shouldn't be compressed, otherwise data is lost
as the code currently makes the whole array have the type of the first
element:
In the above, the valid pointer at position 254 got lost among the
compressed array of nullptr.
While we could disable the array compression when a NULL pointer is
found, the JSON part of the stream still makes part of downtime, so we
should avoid writing unecessary bytes to it.
Keep the array compression in place, but if NULL and non-NULL pointers
are mixed break the array into several type-contiguous pieces :
Now each type-discontiguous region will become a new JSON entry. The
reader should interpret this as a concatenation of values, all part of
the same field.
Parsing the JSON with analyze-script.py now shows the proper data
being pointed to at the places where the pointer is valid and
"nullptr" where there's NULL:

migration: Dump correct JSON format for nullptr replacement
QEMU plays a trick with null pointers inside an array of pointers in a VMSD
field. See 07d4e69147 ("migration/vmstate: fix array of ptr with
nullptrs") for more details on why. The idea makes sense in general, but
it may overlooked the JSON writer where it could write nothing in a
"struct" in the JSON hints section.
We hit some analyze-migration.py issues on s390 recently, showing that some
of the struct field contains nothing, like:
It could be that we hit some null pointers there, and JSON was gone when
they're null pointers.
To fix it, instead of hacking around only at VMStateInfo level, do that
from VMStateField level, so that JSON writer can also be involved. In this
case, JSON writer will replace the pointer array (which used to be a
"struct") to be the real representation of the nullptr field.

Rename vmstate_info_nullptr from "uint64_t" to "nullptr". This vmstate
actually reads and writes just a byte, so the proper name would be

convenient to have a more explicit name that can be identified by the
consumers of the JSON part of the stream.
Change the name to "nullptr" and add support for it in the

hw/intc/riscv_aplic: Fix APLIC in_clrip and clripnum write emulation
In the section "4.7 Precise effects on interrupt-pending bits"
of the RISC-V AIA specification defines that:
"If the source mode is Level1 or Level0 and the interrupt domain
is configured in MSI delivery mode (domaincfg.DM = 1):
The pending bit is cleared whenever the rectified input value is
low, when the interrupt is forwarded by MSI, or by a relevant
write to an in_clrip register or to clripnum."
Update the riscv_aplic_set_pending() to match the spec.

target/i386: Reset TSCs of parked vCPUs too on VM reset
Since commit 5286c3662294 ("target/i386: properly reset TSC on reset")
QEMU writes the special value of "1" to each online vCPU TSC on VM reset
to reset it.
However parked vCPUs don't get that handling and due to that their TSCs
get desynchronized when the VM gets reset.
This in turn causes KVM to turn off PVCLOCK_TSC_STABLE_BIT in its exported
PV clock.
Note that KVM has no understanding of vCPU being currently parked.
Without PVCLOCK_TSC_STABLE_BIT the sched clock is marked unstable in
the guest's kvm_sched_clock_init().
This causes a performance regressions to show in some tests.
Fix this issue by writing the special value of "1" also to TSCs of parked
vCPUs on VM reset.
Reproducing the issue:
1) Boot a VM with "-smp 2,maxcpus=3" or similar
5) Inside the VM run:
# echo "t" >/proc/sysrq-trigger; dmesg | grep sched_clock_stable
Observe the sched_clock_stable() value is 1.
6) Reboot the VM
7) Once the VM boots once again run inside it:
# echo "t" >/proc/sysrq-trigger; dmesg | grep sched_clock_stable
Observe the sched_clock_stable() value is now 0.

meson.build: Disallow libnfs v6 to fix the broken macOS build
The macOS builds in our CI (and possibly other very recent distros)
are currently broken since the update to libnfs version 6 there.
That version apparently comes with a big API breakage. v5.0.3 was
the final release of the old API (see the libnfs commit here:
https://github.com/sahlberg/libnfs/commit/4379837 ).
Disallow version 6.x for now to get the broken CI job working
again. Once somebody had enough time to adapt our code in
block/nfs.c, we can revert this change again.

hw/intc/arm_gicv3_its: Zero initialize local DTEntry etc structs
In the GICv3 ITS model, we have a common coding pattern which has a
local C struct like "DTEntry dte", which is a C representation of an
in-guest-memory data structure, and we call a function such as
get_dte() to read guest memory and fill in the C struct. These
functions to read in the struct sometimes have cases where they will
leave early and not fill in the whole struct (for instance get_dte()
will set "dte->valid = false" and nothing else for the case where it
is passed an entry_addr implying that there is no L2 table entry for
the DTE). This then causes potential use of uninitialized memory
later, for instance when we call a trace event which prints all the
fields of the struct. Sufficiently advanced compilers may produce
-Wmaybe-uninitialized warnings about this, especially if LTO is
enabled.
Rather than trying to carefully separate out these trace events into
"only the 'valid' field is initialized" and "all fields can be
printed", zero-init all the structs when we define them. None of
these structs are large (the biggest is 24 bytes) and having
consistent behaviour is less likely to be buggy.

f6b0de53fb8 ("9pfs: prevent opening special files (CVE-2023-2861)")
caused a regression with security_model=passthrough. When handling a
'Tmknod' request there was a side effect that 'Tmknod' request could fail
as 9p server was trying to adjust permissions:

That's because server was opening the special file to adjust permissions,
however it was using O_PATH and it would have not returned the file
descriptor to guest. So the call to close_if_special_file() on that branch
was incorrect.
Let's lift the restriction introduced by f6b0de53fb8 such that it would
allow to open special files on host if O_PATH flag is supplied, not only
for 9p server's own operations as described above, but also for any client
'Topen' request.
It is safe to allow opening special files with O_PATH on host, because
O_PATH only allows path based operations on the resulting file descriptor
and prevents I/O such as read() and write() on that file descriptor.

balloon_stats_get_all will iterate over guest stats upto the max
VIRTIO_BALLOON_S_NR value, calling visit_type_uint64 to populate
the QObject dict. The dict keys are obtained from the static
array balloon_stat_names which is VIRTIO_BALLOON_S_NR in size.
Unfortunately the way that array is declared results in any
unassigned stats getting a NULL name, which will then cause
visit_type_uint64 to trigger an assert in qobject_output_add_obj.
The balloon_stat_names array was fortunately fully populated with
names until recently:
pulled a change to include/standard-headers/linux/virtio_balloon.h
which increased VIRTIO_BALLOON_S_NR by 6, and failed to add the new
names to balloon_stat_names.
This commit fills in the missing names, and uses a static assert to
guarantee that any future changes to VIRTIO_BALLOON_S_NR will cause
a build failure until balloon_stat_names is updated.
This problem was detected by the Cockpit Project's automated
integration tests on QEMU 9.2.0-rc1.

Both call vga_common_reset() in their reset handler, respectively
pci_secondary_vga_reset() and virtio_vga_base_reset_hold(), which
reset 'big_endian_fb', overwritting the property. This is not
correct: the hardware is expected to keep its configured
endianness during resets.

hw/openrisc/openrisc_sim: keep serial@90000000 as default
We used to only have a single UART on the platform and it was located at
address 0x90000000. When the number of UARTs was increased to 4, the
first UART remained at it's location, but instead of being the first one
to be registered, it became the last.
This caused QEMU to pick 0x90000300 as the default UART, which broke
software that hardcoded the address of 0x90000000 and expected it's
output to be visible when the user configured only a single console.
This caused regressions[1] in the barebox test suite when updating to a
newer QEMU. As there seems to be no good reason to register the UARTs in
inverse order, let's register them by ascending address, so existing
software can remain oblivious to the additional UART ports.
Changing the order of uart registration alone breaks Linux which
was choosing the UART at 0x90000300 as the default for ttyS0. To fix
Linux we fix three things in the device tree:
1. Define stdout-path only one time for the first registered UART
instead of incorrectly defining for each UART.
2. Change the UART alias name from 'uart0' to 'serial0' as almost all
Linux tty drivers look for an alias starting with "serial".
3. Add the UART nodes so they appear in the final DTB in the
order starting with the lowest address and working upwards.
In summary these changes mean that the QEMU default UART (serial_hd(0))
is now setup where:
* serial_hd(0) is the lowest-address UART
* serial_hd(0) is listed first in the DTB
* serial_hd(0) is the /chosen/stdout-path one
* the /aliases/serial0 alias points at serial_hd(0)

hw/openrisc: Fixed undercounting of TTCR in continuous mode
In the existing design, TTCR is prone to undercounting when running in
continuous mode. This manifests as a timer interrupt appearing to
trigger a few cycles prior to the deadline set in SPR_TTMR_TP.
When the timer triggers, the virtual time delta in nanoseconds between
the time when the timer was set, and when it triggers is calculated.
This nanoseconds value is then divided by TIMER_PERIOD (50) to compute
an increment of cycles to apply to TTCR.
However, this calculation rounds down the number of cycles causing the
undercounting.
A simplistic solution would be to instead round up the number of cycles,
however this will result in the accumulation of timing error over time.
This patch corrects the issue by calculating the time delta in
nanoseconds between when the timer was last reset and the timer event.
This approach allows the TTCR value to be rounded up, but without
accumulating error over time.

With a valid file ID (FID) of an open file, it should be possible to send
a 'Tgettattr' 9p request and successfully receive a 'Rgetattr' response,
even if the file has been removed in the meantime. Currently this would
fail with ENOENT.
I.e. this fixes the following misbehaviour with a 9p Linux client:
open("/home/tst/filename", O_RDWR|O_CREAT|O_EXCL, 0600) = 3
unlink("/home/tst/filename") = 0
fstat(3, 0x23aa1a8) = -1 ENOENT (No such file or directory)
This is because 9p server is always using a path name based lstat() call
which fails as soon as the file got removed. So to fix this, use fstat()
whenever we have an open file descriptor already.

for older versions. However, it's still possible that people install
an older version of XCode on a recent version of macOS - which won't
be able to compile QEMU anymore, see for example the ticket here:
Thus let's set the expectations right and refuse older versions of
XCode that do not match the two latest versions of macOS anymore.

tests/functional: Fix the running test case causes loongarch64 to hang
There is a bug in the process of resolving the serial port base address
in the fdt of the loongarch VM UEFI. When both serial port information
and rng-seed information are chosen in the fdt, there is a probability
that the serial port base address cannot be resolved correctly.
This problem can be fixed by updating UEFI.

bios-tables-test: Add data for complex numa test (GI, GP etc)
Given this is a new configuration, there are affects on APIC, CEDT
and DSDT, but the key elements are in SRAT (plus related data in
HMAT). The configuration has node to exercise many different combinations.

1) GI only
2) GP only
3) CPUS only
4) Memory only
5) CPUs + HP memory

answers. Following cropped to remove details of each entry.
Note the zeros represent entries where the target node has no
memory. These could be surpressed but it isn't 'wrong' to provide
them and it is (probably) permissible under ACPI to hotplug memory
into these nodes later.
