178e08a58f Fix savevm after BDRV_FILE size enforcement
We now enforce that you cannot write beyond the end of a non-growable file.
qcow2 files are not growable but we rely on them being growable to do
savevm/loadvm.  Temporarily allow them to be growable by introducing a new
API specifically for savevm read/write operations.

59030a8cd4 gdbstub: Rework configuration via command line and monitor (Jan Kiszka)
Introduce a more canonical gdbstub configuration (system emulation only)
via the new switch '-gdb dev'. Keep '-s' as shorthand for
'-gdb tcp::1234'. Use the same syntax also for the corresponding monitor
command 'gdbserver'. Its default remains to listen on TCP port 1234.

Changes in v4:
 - Rebased over new command line switches meta file

Changes in v3:
 - Fix documentation

Changes in v2:
 - Support for pipe-based like to gdb (target remote | qemu -gdb stdio)
 - Properly update the qemu-doc

0a8e1acd4d qemu-io - an I/O path exerciser (Christoph Hellwig)
This patch adds a new qemu-io tool that links against the block layer and
image formats and allow to exercise them without needing a guest image.
It is inspired by the xfs_io tool which does the same for plain file I/O.
In fact the libxcmd library which is the backend of xfs_io is reused by this
tool in a limited fashing (cmd.[ch] files).

This version tests out most of the plain block I/O commands with the
most notable absent commands beeing snapshot handling and real aio.

This tool is the basis of the I/O path test suite I'm working on right now.

9586fefefe Fix display breakage when resizing the screen (v2) (Avi Kivity)
When the vga resolution changes, a new display surface is not allocated
immediately; instead that is deferred until the next update.  However,
if we're running without a display client attached, that won't happen
and the next bitblt is likely to cause a segfault by overflowing the
display surface.

Fix by reallocating the display immediately when the resolution changes.

Tested with (Windows|Linux) x (cirrus|std) x (curses|sdl).

Changes from v1:
 - fix segfault when switching virtual consoles with curses

2d2431f03f qcow2: fix image creation for large, > ~2TB, images (Chris Wright)
When creating large disk images w/ qcow2 format, qcow2_create is hard
coded to creating a single refcount block.  This is insufficient for
large images, and will cause qemu-img to segfault as it walks off the
end of the refcount block.  Keep track of the space needed during image
create and create proper number of refcount blocks accordingly.

93c65b47a6 Add host_device support to qemu-img. (Nolan Leake)
This patch allows the use a host_device as the destination for "qemu-img
convert".

I added a ->bdrv_create function host_device.  It merely verifies that
the device exists and is large enough.

A check is needed in the qemu-img convert loop to ensure that we write
out all 0 sectors to the host_device.  Otherwise they end up with stale
garbage where all zero sectors were expected.

I also made the check against bdrv_is_allocated enabled for everything
_except_ host devices, since there is no point in making the block
backend write a bunch of zeros just so that we can memcmp them
immediately afterwards.  Host devices can't benefit from this because
there is no way to differentiate between a sector being unallocated
because it was never written, or because it was written with all zeros
and then made a trip through qemu-img convert.

Finally, there is an unrelated fix for a typo in the error message
printed if the destination device does not support ->bdrv_create.

f8de16605c Fix (at least one cause of) qcow2 corruption. (Nolan Leake)
qcow2's get_cluster_offset() scans forward in the l2 table to find other
clusters that have the same allocation status as the first cluster.
This is used by (among others) qcow_is_allocated().

Unfortunately, it was not checking to be sure that it didn't fall off
the end of the l2 table.  This patch adds that check.

The symptom that motivated me to look into this was that
bdrv_is_allocated() was returning false when there was in fact data
there.  This is one of many ways this bug could lead to data corruption.

I checked the other place that scans for consecutive unallocated blocks
(alloc_cluster_offset()) and it appears to be OK:
    nb_clusters = MIN(nb_clusters, s->l2_size - l2_index);
appears to prevent the same problem from occurring.

d19076faca Temporary workaround for ppc on ppc
target-ppc/translate.c puts values of type opcode_t into .opcodes
section, using GCC extension to do so, and hoping that this will make
them appear contiguously and in the source order in the resulting
executable. This assumption is not safe and is known to be violated
with certain versions of GCC, certain flags passed to it and on
certain platforms (gcc 4.3.0, -O and PPC/PPC64 for instance)

The workaround consists of adding -fno-unit-at-a-time to the list of
GCC command line options while building PPC translate.o on a PPC.

4c978075d7 fix format string warnings in block-qcow2.c (Christoph Hellwig)
Recent patches added two compiler warnings about the format string
usage in qcow_read_extensions.  One is printing a uint64_t using
%lu which is incorrect on many platforms as it can be a unsigned
long long, the second one is printing the result of sizeof as
%lu, but it is a size_t so it needs to be printed using %zu.

081501dace check for bs->drv in bdrv_flush (Christoph Hellwig)
All the bdrv_ helpers should check for bs->drv being zero as that means
there is no backend image open.  bdrv_flush fails to perform that check
and can thus cause NULL pointer dereferences.

Found using qemu-io.

999dec57f6 remove dead code in bdrv_check_request (Christoph Hellwig)
Remove code dealing with negative sector numbers for byte access in
bdrv_check_request as sector numbers can't ever be negative.

Previously we supported negative sector counts for byte access, but
never sector numbers.
