786a4ea82e Convert (ffs(val) - 1) to ctz32(val)
This commit was generated mechanically by coccinelle from the following
semantic patch:

@@
expression val;
@@
- (ffs(val) - 1)
+ ctz32(val)

The call sites have been audited to ensure the ffs(0) - 1 == -1 case
never occurs (due to input validation, asserts, etc).  Therefore we
don't need to worry about the fact that ctz32(0) == 32.

3c2784fc86 vga: Expose framebuffer byteorder as a QOM property
The VGA device model now supports having the framebuffer in either endian,
and can be switched between these by the guest via a register in the qext
region.

However, in some cases (e.g. LE OS on the pseries machine) we have
existing guest that don't know about the endian switch register, but other
parts of the qemu code have better information to set a default endianness
than the VGA code does of itself.

In order to allow them to set a correct default endianness in these cases,
without breaking abstraction walls, this patch exposes the VGA framebuffer
endianness via a writable QOM property.

Two for primary qxl cards, when entering/leaving vga mode, which are

One for secondary qxl cards, which is wrong because we don't register

876d516311 spice: fix invalid memory access to vga.vram
vga_common_init() doesn't allow more than 256 MiB vram size and silently
shrinks any larger value.  qxl_dirty_surfaces() used the unshrinked size
via qxl->shadow_rom.surface0_area_size when accessing the memory, which
resulted in segfault.

Add a workaround for this case and an assert if it happens again.

We have to bump the vga memory limit too, because 256 MiB wouldn't have
allowed 8k (it requires more than 128 MiB).
1024 MiB doesn't work, but 512 MiB seems fine.

Now that cursor updates are out of the way qxl needs the refresh timer
only when when running in vga mode, for dirty bitmap checking.  In
native qxl mode the guest will notify us, so we don't need to poll and
can use the idle interval (one refresh wakeup every few seconds).

0b2824e5e4 spice: use bottom half instead of refresh timer for cursor updates
Calling directly doesn't work due to the qxl-render code running in

thread-safe though, so we can use that to kick a cursor update in

d3532a0db0 cirrus: fix blit region check
Issues:
 * Doesn't check pitches correctly in case it is negative.
 * Doesn't check width at all.

Turn macro into functions while being at it, also factor out the check
for one region which we then can simply call twice for src + dst.

This is CVE-2014-8106.

4be746345f hw: Convert from BlockDriverState to BlockBackend, mostly
Device models should access their block backends only through the
block-backend.h API.  Convert them, and drop direct includes of
inappropriate headers.

Just four uses of BlockDriverState are left:

* The Xen paravirtual block device backend (xen_disk.c) opens images
  itself when set up via xenbus, bypassing blockdev.c.  I figure it
  should go through qmp_blockdev_add() instead.

* Device model "usb-storage" prompts for keys.  No other device model
  does, and this one probably shouldn't do it, either.

* ide_issue_trim_cb() uses bdrv_aio_discard() instead of
  blk_aio_discard() because it fishes its backend out of a BlockAIOCB,
  which has only the BlockDriverState.

* PC87312State has an unused BlockDriverState[] member.

The next two commits take care of the latter two.

fa1d36df74 block: Eliminate DriveInfo member bdrv, use blk_by_legacy_dinfo()
The patch is big, but all it really does is replacing

    dinfo->bdrv

by

    blk_bs(blk_by_legacy_dinfo(dinfo))

The replacement is repetitive, but the conversion of device models to
BlockBackend is imminent, and will shorten it to just
blk_legacy_dinfo(dinfo).

Line wrapping muddies the waters a bit.  I also omit tests whether
dinfo->bdrv is null, because it never is.

9e5a25f1c2 qxl: keep going if reaching guest bug on empty area
Xorg server hangs when using xfig and typing a text with space:
 #0  qxl_wait_for_io_command (qxl=<value optimized out>) at qxl_io.c:47
 #1  0x00007f826a49a299 in qxl_download_box (surface=0x221d030, x1=231, y1=259,

       while (!(ram_header->int_pending & QXL_INTERRUPT_IO_CMD))
         usleep (1);

The QXL driver is calling QXL_IO_UPDATE_AREA with an empty area. This
is a guest bug. The call is async and no ack is sent back on guest
bug, so the X server will hang. The driver should be improved to avoid
this situation and also to abort on QXL_INTERRUPT_ERROR. This will be
a different patch series for the driver. However, it is simple enough
to keep qemu running on empty areas update, which is what this patch
provides.

30f1e661b6 console: stop using PixelFormat
With this patch the qemu console core stops using PixelFormat and pixman
format codes side-by-side, pixman format code is the primary way to
specify the DisplaySurface format:

 * DisplaySurface stops carrying a PixelFormat field.
 * qemu_create_displaysurface_from() expects a pixman format now.

Functions to convert PixelFormat to pixman_format_code_t (and back)
exist for those who still use PixelFormat.   As PixelFormat allows
easy access to masks and shifts it will probably continue to exist.

c1b886c45d vbe: rework sanity checks
Plug a bunch of holes in the bochs dispi interface parameter checking.
Add a function doing verification on all registers.  Call that
unconditionally on every register write.  That way we should catch
everything, even changing one register affecting the valid range of
another register.

Some of the holes have been added by commit
e9c6149f6a.  Before that commit the
maximum possible framebuffer (VBE_DISPI_MAX_XRES * VBE_DISPI_MAX_YRES *
32 bpp) has been smaller than the qemu vga memory (8MB) and the checking
for VBE_DISPI_MAX_XRES + VBE_DISPI_MAX_YRES + VBE_DISPI_MAX_BPP was ok.

Some of the holes have been there forever, such as
VBE_DISPI_INDEX_X_OFFSET and VBE_DISPI_INDEX_Y_OFFSET register writes
lacking any verification.

Security impact:

(1) Guest can make the ui (gtk/vnc/...) use memory rages outside the vga
frame buffer as source  ->  host memory leak.  Memory isn't leaked to
the guest but to the vnc client though.

(2) Qemu will segfault in case the memory range happens to include
unmapped areas  ->  Guest can DoS itself.

The guest can not modify host memory, so I don't think this can be used
by the guest to escape.

54a85d4624 vbe: make bochs dispi interface return the correct memory size with qxl
VgaState->vram_size is the size of the pci bar.  In case of qxl not the
whole pci bar can be used as vga framebuffer.  Add a new variable
vbe_size to handle that case.  By default (if unset) it equals
vram_size, but qxl can set vbe_size to something else.

This makes sure VBE_DISPI_INDEX_VIDEO_MEMORY_64K returns correct results
and sanity checks are done with the correct size too.

d16136d22a cirrus: Fix host CPU blits
Commit b2eb849d4b
"CVE-2007-1320 - Cirrus LGD-54XX "bitblt" heap overflow" broke
cpu to video blits.

When the ROP function is called from cirrus_bitblt_cputovideo_next(),
we pass 0 for the pitch but only operate on one line at a time. The
added test was tripping because after the initial substraction, the
pitch becomes negative. Make the test only trip when the height is
larger than one (ie. the pitch is actually used).

This fixes HW cursor support in Windows NT4.0 (which otherwise was
a white rectangle) and general display of icons in that OS when using
8bpp mode.

where the ".fields" indentation was wrong:

     .fields = (VMStateField []) {
and
     .fields =      (VMStateField []) {

Change all the combinations to:

     .fields = (VMStateField[]){

The biggest problem (appart from aesthetics) was that checkpatch complained

The case statements in the CG3 read and write register routines have a maximum
value of CG3_REG_SIZE, so if a value were written to this offset then it
would overflow the register array.

Currently this cannot be exploited since the MemoryRegion restricts accesses
to the range 0 ... CG3_REG_SIZE - 1, but it seems worth clarifying this for
future review and/or static analysis.

35d08458a9 savevm: Remove all the unneeded version_minimum_id_old (rest)
After previous Peter patch, they are redundant.  This way we don't
assign them except when needed.  Once there, there were lots of case
where the ".fields" indentation was wrong:

     .fields = (VMStateField []) {
and
     .fields =      (VMStateField []) {

Change all the combinations to:

     .fields = (VMStateField[]){

The biggest problem (appart from aesthetics) was that checkpatch complained
when we copy&pasted the code from one place to another.

ead7a57df3 ssd0323: fix buffer overun on invalid state load
CVE-2013-4538

s->cmd_len used as index in ssd0323_transfer() to store 32-bit field.
Possible this field might then be supplied by guest to overwrite a
return addr somewhere. Same for row/col fields, which are indicies into
framebuffer array.

To fix validate after load.

Additionally, validate that the row/col_start/end are within bounds;
otherwise the guest can provoke an overrun by either setting the _end
field so large that the row++ increments just walk off the end of the
array, or by setting the _start value to something bogus and then
letting the "we hit end of row" logic reset row to row_start.

For completeness, validate mode as well.

848696bf35 PortioList: Store PortioList in device state
PortioList is an abstraction used for construction of MemoryRegionPortioList
from MemoryRegionPortio. It can be used later to unmap created memory regions.
It also requires proper cleanup because some of the memory inside is allocated
dynamically.

By moving PortioList ot device state we make it possible to cleanup later and
avoid leaking memory.

This change spans several target platforms.  The following testcases cover all
changed lines:
  qemu-system-ppc -M prep
  qemu-system-i386 -vga qxl
  qemu-system-i386 -M isapc -soundhw adlib -device ib700,id=watchdog0,bus=isa.0

this fixes invalid rectangle updates observed after commit 12b316d
with the vmware VGA driver. The issues occured because the server
and client surface update seems to be out of sync at some points
and the max width of the surface is not dividable by
VNC_DIRTY_BITS_PER_PIXEL (16).
