qemu-iotests supports the -nocache option which makes the tests run with
cache=none. For blkdebug tests with qcow2 this means that we may see
test results that differ from cache=writethrough. This patch makes the
diff a bit smaller and therefore easier to review.

Block layer tests that involve QMP commands rather than qemu-img or
qemu-io are not well-suited for shell scripting. This patch adds a
Python module which allows tests to be written in Python instead.
The basic API is:
VM - class for launching and interacting with a VM
QMPTestCase - abstract base class for tests that use QMP
qemu_img() - wrapper function for invoking qemu-img
qemu_io() - wrapper function for invoking qemu-io
imgfmt - the image format under test (e.g. qcow2, qed)
test_dir - scratch directory path for temporary files
main() - entry point for running tests

This adds the QMP command for blockdev-group-snapshot-sync. It
takes an array in as the input, for the argument devlist. The
array consists of the following elements:
+ device: device to snapshot. e.g. "ide-hd0", "virtio0"
+ snapshot-file: path & file for the snapshot image. e.g. "/tmp/file.img"
+ format: snapshot format. e.g., "qcow2". Optional
There is no HMP equivalent for the command.

This is a QAPI/QMP only command to take a snapshot of a group of
devices. This is similar to the blockdev-snapshot-sync command, except
blockdev-group-snapshot-sync accepts a list devices, filenames, and
formats.
It is attempted to keep the snapshot of the group atomic; if the
creation or open of any of the new snapshots fails, then all of
the new snapshots are abandoned, and the name of the snapshot image
that failed is returned. The failure case should not interrupt
any operations.
Rather than use bdrv_close() along with a subsequent bdrv_open() to
perform the pivot, the original image is never closed and the new
image is placed 'in front' of the original image via manipulation
of the BlockDriverState fields. Thus, once the new snapshot image
has been successfully created, there are no more failure points
before pivoting to the new snapshot.
This allows the group of disks to remain consistent with each other,
even across snapshot failures.

Image files that make qemu-img info read several gigabytes into the

if an extension claims to be larger than the header extension area.
Signed-off-by: Kevin Wolf <kwolf@redhat.com>
Reviewed-by: Stefan Hajnoczi <stefanha@linux.vnet.ibm.com>
The spec says that the length of extensions is padded to 8 bytes, not
the offset. Currently this is the same because the header size is a
multiple of 8, so this is only about compatibility with future changes
to the header size.
While touching it, move the calculation to a common place instead of
duplicating it for each header extension type.

Floppies can be simple or double-sided. However, current code
was only taking the common case into account (ie 2 sides).
This repairs single-sided floppies, which where totally broken
before this patch : for track > 0, wrong sector number was
calculated, and data was read/written at wrong place on
underlying device.
Fortunately, only some 360 kB floppies are single-sided, so

The guest network stack might DHCPREQUEST an address that the slirp built
in dhcp server can't let it have - for example if the guest has an old
leases file from another network configuration. In this case the dhcp
server should and does reject the request and prepares to send a DHCPNAK
to the client.
However, in this case the daddr variable in bootp_reply() is set to
0.0.0.0. Shortly afterwards, it unconditionally attempts to pre-insert the
new client address into the ARP table. This causes an assertion failure in
arp_address_add() because of the 0.0.0.0 address.
According to RFC2131, DHCPNAK messages for clients on the same subnet
must be sent to the broadcast address (S3.2, subpoint 2).

queue, we failed to restore this ordering. Also, we did not properly
deal with changes to Slirp::next_m.
Instead of a cumbersome roll back, this fix simply avoids any changes
until we know if the packet was actually sent. Both fixes crashes due
to inconsistent queues and simplifies the logic.

* qemu_system_wakeup_request is supposed to be called on events
which should wake up the guest.
* qemu_register_suspend_notifier can be used to register a notifier
which will be called when the guest is suspended. Machine types
and device models can hook in there to modify state if needed.
* qemu_register_wakeup_notifier can be used to register a notifier

* qemu_system_wakeup_enable can be used to enable/disable wakeup
