ui/win32: fix potential use-after-free with dbus shared memory
DisplaySurface may be free before the pixman image is freed, since the
image is refcounted and used by different objects, including pending
dbus messages.
Furthermore, setting the destroy function in
create_displaysurface_from() isn't appropriate, as it may not be used,
and may be overriden as in ramfb.
Set the destroy function when the shared handle is set, use the HANDLE
directly for destroy data, using a single common helper
qemu_pixman_win32_image_destroy().

hw/char/pl011: Use correct masks for IBRD and FBRD
In commit b88cfee90268cad we defined masks for the IBRD and FBRD
integer and fractional baud rate divider registers, to prevent the
guest from writing invalid values which could cause division-by-zero.
Unfortunately we got the mask values the wrong way around: the FBRD
register is six bits and the IBRD register is 16 bits, not
vice-versa.
You would only run into this bug if you programmed the UART to a baud
rate of less than 9600, because for 9600 baud and above the IBRD
value will fit into 6 bits, as per the table in
https://developer.arm.com/documentation/ddi0183/g/programmers-model/register-descriptions/fractional-baud-rate-register--uartfbrd
The only visible effects would be that the value read back from
the register by the guest would be truncated, and we would
print an incorrect baud rate in the debug logs.

hw/sd/sdcard: Fix handling of disabled boot partitions
The enable bits in the EXT_CSD_PART_CONFIG ext_csd register do *not*
specify whether the boot partitions exist, but whether they are enabled
for booting. Existence of the boot partitions is specified by a
EXT_CSD_BOOT_MULT != 0.
Currently, in the case of boot-partition-size=1M and boot-config=0,
Linux detects boot partitions of 1M. But as sd_bootpart_offset always
returns 0, all reads/writes are mapped to the same offset in the backing
file.
Fix this bug by calculating the offset independent of which partition is
enabled for booting.
This bug is unlikely to affect many users with QEMU's current set of
boards, because only aspeed sets boot-partition-size, and it also
sets boot-config to 8. So to run into this a user would have to
manually mark the boot partition non-booting from within the guest.

target/arm: Avoid target_ulong for physical address lookups
target_ulong is typedef'ed as a 32-bit integer when building the
qemu-system-arm target, and this is smaller than the size of an
intermediate physical address when LPAE is being used.
Given that Linux may place leaf level user page tables in high memory
when built for LPAE, the kernel will crash with an external abort as
soon as it enters user space when running with more than ~3 GiB of
system RAM.
So replace target_ulong with vaddr in places where it may carry an
address value that is not representable in 32 bits.

Allow overlapping request by removing the assert that made it
impossible. There are only two callers:
1. block_copy_task_create()
It already asserts the very same condition before calling
reqlist_init_req().
2. cbw_snapshot_read_lock()
There is no need to have read requests be non-overlapping in
copy-before-write when used for snapshot-access. In fact, there was no
protection against two callers of cbw_snapshot_read_lock() calling
reqlist_init_req() with overlapping ranges and this could lead to an
assertion failure [1].
In particular, with the reproducer script below [0], two
cbw_co_snapshot_block_status() callers could race, with the second
calling reqlist_init_req() before the first one finishes and removes
its conflicting request.

target/ppc: Fix migration of CPUs with TLB_EMB TLB type
In vmstate_tlbemb a cut-and-paste error meant we gave
this vmstate subsection the same "cpu/tlb6xx" name as
the vmstate_tlb6xx subsection. This breaks migration load
for any CPU using the TLB_EMB CPU type, because when we
see the "tlb6xx" name in the incoming data we try to
interpret it as a vmstate_tlb6xx subsection, which it
isn't the right format for:
$ qemu-system-ppc -drive

Correct the incorrect vmstate section name. Since migration
for these CPU types was completely broken before, we don't
need to care that this is a migration compatibility break.

That commit dropped the masking of the IAOQ addresses while copying them

the full gva is formed with the help of hppa_form_gva_psw().
So, when running in linux-user mode on an emulated 64-bit CPU, we need
to mask to a 32-bit address space at the very end in hppa_form_gva_psw()

softmmu/physmem: fix memory leak in dirty_memory_extend()
As reported by Peter, we might be leaking memory when removing the
highest RAMBlock (in the weird ram_addr_t space), and adding a new one.
We will fail to realize that we already allocated bitmaps for more
dirty memory blocks, and effectively discard the pointers to them.
Fix it by getting rid of last_ram_page() and by remembering the number
of dirty memory blocks that have been allocated already.
While at it, let's use "unsigned int" for the number of blocks, which
should be sufficient until we reach ~32 exabytes.
Looks like this leak was introduced as we switched from using a single
bitmap_zero_extend() to allocating multiple bitmaps:
bitmap_zero_extend() relies on g_renew() which should have taken care of
this.

softmmu: Support concurrent bounce buffers
When DMA memory can't be directly accessed, as is the case when
running the device model in a separate process without shareable DMA
file descriptors, bounce buffering is used.
It is not uncommon for device models to request mapping of several DMA
regions at the same time. Examples include:
* net devices, e.g. when transmitting a packet that is split across
several TX descriptors (observed with igb)
* USB host controllers, when handling a packet with multiple data TRBs
(observed with xhci)
Previously, qemu only provided a single bounce buffer per AddressSpace
and would fail DMA map requests while the buffer was already in use. In
turn, this would cause DMA failures that ultimately manifest as hardware
errors from the guest perspective.
This change allocates DMA bounce buffers dynamically instead of
supporting only a single buffer. Thus, multiple DMA mappings work
correctly also when RAM can't be mmap()-ed.
The total bounce buffer allocation size is limited individually for each
AddressSpace. The default limit is 4096 bytes, matching the previous
maximum buffer size. A new x-max-bounce-buffer-size parameter is
provided to configure the limit for PCI devices.

On GICv2 and later, level triggered interrupts are pending when either
the interrupt line is asserted or the interrupt was made pending by a
GICD_ISPENDRn write. Making a level triggered interrupt pending by
software persists until either the interrupt is acknowledged or cleared
by writing GICD_ICPENDRn. As long as the interrupt line is asserted,
the interrupt is pending in any case.
This logic is transparently implemented in gic_test_pending() for
GICv1 and GICv2. The function combines the "pending" irq_state flag
(used for edge triggered interrupts and software requests) and the
line status (tracked in the "level" field). However, we also
incorrectly set the pending flag on a guest write to GICD_ISENABLERn
if the line of a level triggered interrupt was asserted. This keeps
the interrupt pending even if the line is de-asserted after some
time.
This incorrect logic is a leftover of the initial 11MPCore GIC
implementation. That handles things slightly differently to the
architected GICv1 and GICv2. The 11MPCore TRM does not give a lot of
detail on the corner cases of its GIC's behaviour, and historically
we have not wanted to investigate exactly what it does in reality, so
QEMU's GIC model takes the approach of "retain our existing behaviour
for 11MPCore, and implement the architectural standard for later GIC
revisions".
On that basis, commit 8d999995e45c10 in 2013 is where we added the
"level-triggered interrupt with the line asserted" handling to
gic_test_pending(), and we deliberately kept the old behaviour of
gic_test_pending() for REV_11MPCORE. That commit should have added
the "only if 11MPCore" condition to the setting of the pending bit on
writes to GICD_ISENABLERn, but forgot it.
Add the missing "if REV_11MPCORE" condition, so that our behaviour
on GICv1 and GICv2 matches the GIC architecture requirements.

.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.

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:

system/vl.c: Print machine name, not "(null)", for unknown machine types
In commit 412d294ffdc 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 the right variable, so we produce more helpful output:

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.

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.

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.

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.

Since commit 4ccd5fe22feb95137d325f422016a6473541fe9f ('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

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.

Directly invoking the DeviceClass::reset method is a bad idea,
because if the device is using three-phase reset then it relies on
