Sylvain Garrigues 27a5dc7be6 bcm2835_property: use cached values when querying framebuffer
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
client requested.

Gerd Hoffmann fd3c136b3e vga: make sure vga register setup for vbe stays intact (CVE-2016-3712).
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.

Gerd Hoffmann 3bf1817079 vga: fix banked access bounds checking (CVE-2016-3710)
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}
instead.

Igor Mammedov 1dbfd7892b acpi: fix bios linker loadder COMMAND_ALLOCATE on bigendian host
'make check' fails with:

ERROR:tests/bios-tables-test.c:493:load_expected_aml:
   assertion failed: (g_file_test(aml_file, G_FILE_TEST_EXISTS))

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.

Michael Roth df18b2db69 spapr_drc: fix aborts during DRC-count based hotplug
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().

Gerd Hoffmann f419a626c7 usb/uhci: move pid check
commit "5f77e06 usb: add pid check at the first of uhci_handle_td()"
moved the pid verification to the start of the uhci_handle_td function,
to simplify the error handling (we don't have to free stuff which we
didn't allocate in the first place ...).

Problem is now the check fires too often, it raises error IRQs even for
TDs which we are not going to process because they are not set active.

So, lets move down the check a bit, so it is done only for active TDs,
but still before we are going to allocate stuff to process the requested
transfer.

Thomas Huth da34fed707 hw/ppc/spapr: Fix crash when specifying bad parameters to spapr-pci-host-bridge
QEMU currently crashes when using bad parameters for the
spapr-pci-host-bridge device:

$ qemu-system-ppc64 -device spapr-pci-host-bridge,buid=0x123,liobn=0x321,mem_win_addr=0x1,io_win_addr=0x10
Segmentation fault

The problem is that spapr_tce_find_by_liobn() might return NULL, but
the code in spapr_populate_pci_dt() does not check for this condition
and then tries to dereference this NULL pointer.
Apart from that, the return value of spapr_populate_pci_dt() also
has to be checked for all PCI buses, not only for the last one, to
make sure we catch all errors.

Sylvain Garrigues b4850e5ae9 hw/arm/boot: always clear r0 when booting kernels
The 32-bit ARM Linux kernel booting ABI requires that r0 is 0
when calling the kernel image. A bug in commit 10b8ec73e6
meant that for boards which use the write_board_setup hook (which
means "highbank", "midway", "raspi2" and "xilinx-zynq-a9") we
were incorrectly skipping the "clear r0" instruction in the
mini-bootloader. Use the right offset in the "add lr, pc, #n"
instruction so that we return from the board-setup code to the
correct place.

Michael S. Tsirkin 5eb0b194e9 cadence_uart: bounds check write offset
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.
