fd040174ac block: qemu-iotests - test for live migration
This is an initial, simple live migration test from one
running VM to another, using monitor commands.

This is also an example of using the new common.qemu functions
for controlling multiple running qemu instances, for tests that
need a live qemu vm.

e86e869770 block: qemu-iotests - update 085 to use common.qemu
The new functionality of common.qemu implements the QEMU control
and communication functionality that was originally in test 085.

This removes that now-duplicate functionality, and uses the
common.qemu functions.

The QEMU commandline changes slightly due to this; in addition to
monitor and qmp i/o options, the new QEMU commandline from inside
common.qemu now introduces -machine accel=qtest.

e940bc13ee block: qemu-iotests - add common.qemu, for bash-controlled qemu tests
This creates some common functions for bash language qemu-iotests
to control, and communicate with, a running QEMU process.

4 functions are introduced:

    1. _launch_qemu()
        This launches the QEMU process(es), and sets up the file
        descriptors and fifos for communication.  You can choose to
        launch each QEMU process listening for either QMP or HMP
        monitor.  You can call this function multiple times, and
        save the handle returned from each.  The returned handle is
        in $QEMU_HANDLE.  You must copy this value.

Commands 2 and 3 use the handle received from _launch_qemu(), to talk
to the appropriate process.

    2. _send_qemu_cmd()
        Sends a command string, specified by $2, to QEMU.  If $3 is
        non-NULL, _send_qemu_cmd() will wait to receive $3 as a
        required result string from QEMU.  Failure to receive $3 will
        cause the test to fail.  The command can optionally be retried
        $qemu_cmd_repeat number of times.  Set $qemu_error_no_exit
        to not force the test the fail on exit; in this case,
        $QEMU_STATUS[$1] will be set to -1 on failure.

    3. _timed_wait_for()
        Waits for a response, for up to a default of 10 seconds.  If
        $2 is not seen in that time (anywhere in the response), then
        the test fails.  Primarily used by _send_qemu_cmd, but could
        be useful standalone, as well.  To prevent automatic exit
        (and therefore test failure), set $qemu_error_no_exit to a
        non-NULL value.  If $silent is a non-NULL value, then output
        to stdout will be suppressed.

    4. _cleanup_qemu()
        Kills the running QEMU processes, and removes the fifos.

b1e6fc0817 block: Fix open flags with BDRV_O_SNAPSHOT
The immediately visible effect of this patch is that it fixes committing
a temporary snapshot to its backing file. Previously, it would fail with
a "permission denied" error because bdrv_inherited_flags() forced the
backing file to be read-only, ignoring the r/w reopen of bdrv_commit().

The bigger problem this revealed is that the original open flags must
actually only be applied to the temporary snapshot, and the original
image file must be treated as a backing file of the temporary snapshot
and get the right flags for that.

f915db07ef iotests: Use configured python
Currently, QEMU's iotests rely on /usr/bin/env to start the correct
Python (that is, at least Python 2.4, but not 3). On systems where
Python 3 is the default, the user has no clean way of making the iotests
use the correct binary.

This commit makes the iotests use the Python selected by configure.

ad0a118fa3 tests/tcg: Fix compilation of test_path
The test_path binary is (unlike the other test binaries in tests/tcg)
actually intended to be compiled with the same compiler used to build
the main QEMU executables. It actually #includes a number of the
QEMU source files in an attempt to unit-test the util/path.c functions,
and so if it is not compiled with the same compiler used by configure
to set CONFIG_ settings then it is liable to fail to build.
Fix the makefile to build it with the default C compiler rules, not
CC_I386, and fix the test itself not to include a lot of unnecessary
trace related source files which cause the build to fail if the trace
backend is anything other than 'simple'.

0fb6395c0c Use error_is_set() only when necessary (again)
error_is_set(&var) is the same as var != NULL, but it takes
whole-program analysis to figure that out.  Unnecessarily hard for
optimizers, static checkers, and human readers.  Commit 84d18f0 dumbed
it down to obvious, but a few more have crept in since, and
documentation was overlooked.  Dumb these down, too.

f2d953ec31 block: Catch duplicate IDs in bdrv_new()
Since commit f298d071, block devices added with blockdev-add don't have
a QemuOpts around in dinfo->opts. Consequently, we can't rely any more
on QemuOpts catching duplicate IDs for block devices.

This patch adds a new check for duplicate IDs to bdrv_new(), and moves
the existing check that the ID isn't already taken for a node-name there
as well.

da15ee5134 block: Catch integer overflow in bdrv_rw_co()
Insanely large requests could cause an integer overflow in
bdrv_rw_co() while converting sectors to bytes. This patch catches the
problem and returns an error (if we hadn't overflown the integer here,
bdrv_check_byte_request() would have rejected the request, so we're not
breaking anything that was supposed to work before).

We actually do have a test case that triggers behaviour where we
accidentally let such a request pass, so that it would return success,
but read 0 bytes instead of the requested 4 GB. It fails now like it
should.

If the vdi block driver wants to be able to deal with huge images, it
can't read the whole block bitmap at once into memory like it does
today, but needs to use a metadata cache like qcow2 does.

b998875dcf block: Fix snapshot=on for protocol parsed from filename
Since commit 9fd3171a, BDRV_O_SNAPSHOT uses an option QDict to specify
the originally requested image as the backing file of the newly created
temporary snapshot. This means that the filename is stored in
"file.filename", which is an option that is not parsed for protocol
names. Therefore things like -drive file=nbd:localhost:10809 were
broken because it looked for a local file with the literal name
'nbd:localhost:10809'.

This patch changes the way BDRV_O_SNAPSHOT works once again. We now open
the originally requested image as normal, and then do a similar
operation as for live snapshots to put the temporary snapshot on top.
This way, both driver specific options and parsed filenames work.

As a nice side effect, this results in code movement to factor
bdrv_append_temp_snapshot() out. This is a good preparation for moving
its call to drive_init() and friends eventually.

e3fa4bfa72 block: Don't parse 'filename' option
When using the QDict option 'filename', it is supposed to be interpreted
literally. The code did correctly avoid guessing the protocol from any
string before the first colon, but it still called bdrv_parse_filename()
which would, for example, incorrectly remove a 'file:' prefix in the
raw-posix driver.

4c2e5f8f46 qcow2: Flush metadata during read-only reopen
If lazy refcounts are enabled for a backing file, committing to this
backing file may leave it in a dirty state even if the commit succeeds.
The reason is that the bdrv_flush() call in bdrv_commit() doesn't flush
refcount updates with lazy refcounts enabled, and qcow2_reopen_prepare()
doesn't take care to flush metadata.

In order to fix this, this patch also fixes qcow2_mark_clean(), which
contains another ineffective bdrv_flush() call beause lazy refcounts are
disabled only afterwards. All existing callers of qcow2_mark_clean()
either don't modify refcounts or already flush manually, so that this
fixes only a latent, but not yet actually triggerable bug.

Another instance of the same problem is live snapshots. Again, a real
corruption is prevented by an explicit flush for non-read-only images in
external_snapshot_prepare(), but images using lazy refcounts stay dirty.

afbcc40bee parallels: Fix catalog size integer overflow (CVE-2014-0143)
The first test case would cause a huge memory allocation, leading to a
qemu abort; the second one to a too small malloc() for the catalog
(smaller than s->catalog_size), which causes a read-only out-of-bounds
array access and on big endian hosts an endianess conversion for an
undefined memory area.

The sample image used here is not an original Parallels image. It was
created using an hexeditor on the basis of the struct that qemu uses.
Good enough for trying to crash the driver, but not for ensuring
compatibility.
