As the framebuffer settings are copied into the result message before it is
reconfigured, inconsistent behavior can happen when, for instance, you set with
a single message the width, height, and depth, and ask at the same time to
allocate the buffer and get the pitch and the size.
In this case, the reported pitch and size would be incorrect as they were
computed with the initial values of width, height and depth, not the ones the

Call vbe_update_vgaregs() when the guest touches GFX, SEQ or CRT
registers, to make sure the vga registers will always have the
values needed by vbe mode. This makes sure the sanity checks
applied by vbe_fixup_regs() are effective.
Without this guests can muck with shift_control, can turn on planar
vga modes or text mode emulation while VBE is active, making qemu
take code paths meant for CGA compatibility, but with the very
large display widths and heigts settable using VBE registers.
Which is good for one or another buffer overflow. Not that
critical as they typically read overflows happening somewhere
in the display code. So guests can DoS by crashing qemu with a
segfault, but it is probably not possible to break out of the VM.

vga allows banked access to video memory using the window at 0xa00000
and it supports a different access modes with different address
calculations.
The VBE bochs extentions support banked access too, using the
VBE_DISPI_INDEX_BANK register. The code tries to take the different
address calculations into account and applies different limits to
VBE_DISPI_INDEX_BANK depending on the current access mode.
Which is probably effective in stopping misprogramming by accident.
But from a security point of view completely useless as an attacker
can easily change access modes after setting the bank register.
Drop the bogus check, add range checks to vga_mem_{readb,writeb}

since commit:
caf50c7166
tests: pc: acpi: drop not needed 'expected SSDT' blobs
Assert happens because qemu-system-x86_64 generates
SSDT table and test looks for a corresponding expected
table to compare with.
However there is no expected SSDT blob anymore, since
QEMU souldn't generate one. As it happens BIOS is not
able to read ACPI tables from QEMU and fallbacks to
embeded legacy ACPI codepath, which generates SSDT.
That happens due to wrongly sized endiannes conversion
which makes
uint8_t BiosLinkerLoaderEntry.alloc.zone
end up with 0 due to truncation of 32 bit integer
which on host is 1 or 2.
Fix it by dropping invalid cpu_to_le32() as uint8_t
doesn't require any conversion.

CPU/memory resources can be signalled en-masse via
spapr_hotplug_req_add_by_count(), and when doing so, actually change
the meaning of the 'drc' parameter passed to
spapr_hotplug_req_event() to be a count rather than an index.
f40eb92 added a hook in spapr_hotplug_req_event() to record when a
device had been 'signalled' to the guest, but that code assumes that
drc is always an index. In cases where it's a count, such as memory
hotplug, the DRC lookup will fail, leading to an assert.
Fix this by only explicitly setting the signalled state for cases where
we are doing PCI hotplug.
For other resources types, since we cannot selectively track whether a
resource has been signalled in cases where we signal attach as a count,
set the 'signalled' state to true immediately upon making the
resource available via drck->attach().

cuda: fix off-by-one error in SET_TIME command
Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
cadence_uart_init() initializes an I/O memory region of size 0x1000
bytes. However in uart_write(), the 'offset' parameter (offset within
region) is divided by 4 and then used to index the array 'r' of size
CADENCE_UART_R_MAX which is much smaller: (0x48/4). If 'offset>>=2'
exceeds CADENCE_UART_R_MAX, this will cause an out-of-bounds memory
write where the offset and the value are controlled by guest.
This will corrupt QEMU memory, in most situations this causes the vm to
crash.
Fix by checking the offset against the array size.

Commit "156a2e4 ehci: make idt processing more robust" tries to avoid a

First it misses the case of siTDs, and second it reportedly breaks

So lets go for a different approach: just count the number of iTDs and
siTDs we have seen per frame and apply a limit. That should really

The balloon code currently calls madvise() with TARGET_PAGE_SIZE as
length parameter. Since the virtio-balloon protocol is always based
on 4k pages, no matter what the host and guest are using as page size,
this could cause problems: If TARGET_PAGE_SIZE is bigger than 4k, the
madvise call also destroys the 4k areas after the current one - which
might be wrong since the guest did not want free that area yet (in
case the guest used as smaller MMU page size than the hard-coded
TARGET_PAGE_SIZE). So to fix this issue, introduce a proper define
called BALLOON_PAGE_SIZE (which is 4096) to use this as the size
parameter for the madvise() call instead.

IRQ 5 used by TPM conflicts with PNP0C0F IRQs,
as result Windows fails driver initialization with reason
'device cannot find enough free resources'
But if TPM._CRS.IRQ entry is commented out, Windows
seems to initialize driver without errors as it doesn't
notice possible conflict and it seems to work
probably due to a link with IRQ 5 being unused/disabled.
So temporary comment out TPM._CRS.IRQ to 'fix'
regression in TPM, with intent to fix it correctly
later i.e.:
1. pick unused IRQ as default one for TPM
2. fetch IRQ value from device model so that user
