[Qemu-devel] [PATCH v2 0/9] raw: Prohibit dangerous writes for probed images |

See the commit message of patch 7 for the why and how. This series
will probably be only part of the solution and doesn't mean that we
should stop looking for other patches which improve different parts of
the problem.
See the mailing list thread "Image probing: how it can be insecure, and
what we could do about it" for the complete context.
v2:
- Fixed offset in qemu_iovec_concat [Kevin]
- Added paragraph to patch 7 explaining that we're not breaking
additional cases, but only change the failure mode of already
broken scenarios [Max]
- Added a warning when opening an image in "restricted raw" mode,
which required a few more patches to make the test cases avoid
this warning [Markus]
Kevin Wolf (8):
qemu-io: Allow explicitly specifying format
qemu-iotests: Use qemu-io -f $IMGFMT
qemu-iotests: Add qemu-io format option in Python tests
qtests: Specify image format explicitly
block: Read only one sector for format probing
raw: Prohibit dangerous writes for probed images
qemu-iotests: Fix stderr handling in common.qemu
qemu-iotests: Test writing non-raw image headers to raw image
Markus Armbruster (1):
block: Factor bdrv_probe_all() out of find_image_format()
