274fb0e1ed check SCSI read/write requests against max LBA (Rik van Riel)
The bdrv layer uses a signed offset. Furthermore, block-raw-posix
only seeks when that offset is positive. Passing a negative offset
to block-raw-posix can result in data being written at the current
seek cursor's position.

It may be possible to exploit this to seek to the end of the disk
and extend the virtual disk by writing data to a negative sector
offset.  After a reboot, this could lead to the guest having a
larger disk than it had before.

Close the hole by sanity checking the lba against the size of the
disk.

dd5e3b1771 MTRR support on x86, part 2 (Carl-Daniel Hailfinger)
Load and save MTRR state together with machine state.

Add support for the MTRRcap MSR which is used by the latest Bochs BIOS
and some operating systems.

Fix a typo in ext2_feature_name.

With this patch, MTRR emulation should be good enough to not trigger any
sanity checks in well behaved BIOS/kernel code.
Some corner cases for BIOS/firmware usage remain to be implemented, but
that can be deferred to another patch.
Also, MTRR accesses on hardware not supporting MTRRs should cause #GP.
That can be enforced by another patch as well.

22bf14582a fix raw_aio_read\write error handling (Stefano Stabellini)
Currently when qemu_paio_read or qemu_paio_write return an error we call
qemu_aio_release without removing the request from the list.
I know that in the current implementation qemu_paio_write\read don't return
any error, but still the behavior is wrong, especially considering
that the implementation of these two functions is likely to change in is
the future.
This patch fixes the problem adding a raw_aio_remove function that
removes the callback from the queue and also calls qemu_aio_release.
raw_aio_remove is called by raw_aio_read, raw_aio_write and
raw_aio_cancel.

c1c0438c80 SCSI divide capacity by s->cluster_size (Rik van Riel)
Paul Brook pointed out that the number of sectors reported
by the SCSI read capacity commands needs to be divided by
s->cluster_size, because bdrv_get_geometry reports the number
of 512 byte sectors, while emulated CDROMs report 2048 byte
sectors back to the guest.

This has no consequences for emulated hard disks, which use
a cluster size of 1.

86106e5920 support >2TB SCSI disks (Rik van Riel)
Implement SCSI READ(16), WRITE(16) and SAI READ CAPACITY(16) commands,
so SCSI disks larger than 2TB can work with guests that support these
newer SCSI commands.

The cast to (uint64_t) is needed because otherwise gcc will use a
signed int, which gets sign extended into uint64_t lba, resulting
in bad block numbers for READ 10 and READ 16 with block numbers
larger than 2^31.

e035b43d7c fix signed/unsigned overflows in SCSI disk (Rik van Riel)
Sector numbers can overflow on a virtual scsi disk of over 1TB
in size.  Qemu's bdrv_read expects an int64_t, so fix the overflow
by going to that data type.

On large disks, we clip the capacity to 2TB instead of returning
"capacity modulo 2TB".

Turn sector_count into an unsigned to prevent a signed/unsigned
overflow with SCSI transfers larger than 2TB.  We're unlikely to
ever hit this bug, but fixing it is just one line.

8c6c919e28 kvm-x86: Remove eflags conversion into emulator format (Jan Kiszka)
It seems that the conversion of the kernel-delivered eflags state into
qemu's internal split representation was once needed in an older kvm
design (register read-back may have taken place from inside cpu_exec).
Today it is plain wrong and causes incorrect cpu state reporting (gdb,
monitor) and should also corrupt its saving (savevm, migration). Drop
the related lines.

The HPET emulation can disable the i8254 when the HPET is

But if it does, the i8254 doesn't have to be running, so

if it's not.

This fixes a segmentation fault when running Mac OS X as

As for copyright, I don't own all of it.  Dan does, so I will defer to
him.  Any of my patches I will gladly license to the 3-part BSD
license.  My interest in re-licensing was because we didn't have ready
info to contact Dan.  If Dan would like to port Slirp back out of

165d9b82eb MTRR support on x86 (Carl-Daniel Hailfinger)
The current codebase ignores MTRR (Memory Type Range Register)
configuration writes and reads because Qemu does not implement caching.
All BIOS/firmware in know of for x86 do implement a mode called
Cache-as-RAM (CAR) which locks down the CPU cache lines and uses the CPU
cache like RAM before RAM is enabled. Qemu assumes RAM is accessible
from the start, but it would be nice to be able to run real
BIOS/firmware in Qemu. For that, we need CAR support and for CAR support
we have to support MTRRs.

This patch is a first step in that direction. MTRRs are MSRs supported
by all recent x86 CPUs, even old i586. Besides influencing cache, the
MTRRs can be written and read back, so discarding MTRR writes violates
the expectations of existing code out there.

An added benefit of this patch is that it fixes the following Linux
kernel error message present in recent kernels (provided the BIOS has
the recent MTRR patches applied):

28c699a2b6 build system: Further improve quiet mode (Jan Kiszka)
Derived from Stuart Brady's patch: Show the target directory as prefix
to the current module when building in quiet mode. This helps to gain
overview of the current build progress, specifically when running
parallelized builds.

Furthermore, suppress make command echoing when entering subdirs and
replace $(subst subdir-,,$@) with $* in the related rule.

1b0f9cc26b Enabled building of x86_64 code on Mac OS X (Alexander Graf)
Mac OS X 10.5 supports 64-bit userspace on an x86_64 kernel and
by default uses 32-bit userspace applications, so the detection for
the host architecture fails.

This patch enabled building of x86_64 code on x86_64 capable CPUS
with Mac OS X.

deb54399df Define PCI vendor and device IDs in pci.h (Stuart Brady)
This patch defines PCI vendor and device IDs in pci.h (matching those
from Linux's pci_ids.h), and uses those definitions where appropriate.

Change from v1:
  Introduces pci_config_set_vendor_id() / pci_config_set_device_id()
  accessors as suggested by Anthony Liguori.

90a1e3c0b5 vnc fixes and improvements (Stefano Stabellini)
this patch fixes a bug and improves the generic pixel conversion
function in vnc.c.
The bug is that when a new vnc client connects we need to reset the flag
has_WMVi but currently we don't.
The generic pixel conversion function is vnc_convert_pixel and currently
is not very efficient since uses the division and multiplication
operators.
To make it more efficient I changed to use bit shift operators instead.

99b3718ee1 Use the default subsystem vendor ID for virtio devices (Mark McLoughlin)
A subsystem vendor ID of zero isn't allowed, so we use our
default ID.

Gerd points out that although the PCI subsystem vendor ID is
treated by the guest as the virtio vendor ID:

   /* we use the subsystem vendor/device id as the virtio vendor/device
    * id.  this allows us to use the same PCI vendor/device id for all
    * virtio devices and to identify the particular virtio driver by
    * the subsytem ids */
    vp_dev->vdev.id.vendor = pci_dev->subsystem_vendor;
    vp_dev->vdev.id.device = pci_dev->subsystem_device;

it looks like only the device ID is used right now:

   # grep virtio modules.alias
   alias virtio:d00000001v* virtio_net
   alias virtio:d00000002v* virtio_blk
   alias virtio:d00000003v* virtio_console
   alias virtio:d00000004v* virtio-rng
   alias virtio:d00000005v* virtio_balloon
   alias pci:v00001AF4d*sv*sd*bc*sc*i* virtio_pci
   alias virtio:d00000009v* 9pnet_virtio

so setting the subsystem vendor id to something != zero shouldn't cause
trouble.

36bee1e3a4 target-ppc: always load kernel to KERNEL_LOAD_ADDR
Linux changed its physical address location in the elf header from
0xc0000000 to 0 on 2.6.25, causing later kernels to fail booting
with the -kernel option.

This patch assures that the lowest segment in the elf binary is loaded
to KERNEL_LOAD_ADDR, which is where the firmware expects it.
