In the past, we have had CVEs caused by qemu probing one image type
when an image started out as another but the guest was able to modify
content. The solution to those CVEs was to encode backing format
information into qcow2, to ensure that once we make a decision, we
don't have to probe any further. However, we failed to enforce this
at the time. And now that libvirt is switching to -blockdev, it has
come back to bite us: with -block, libvirt had no easy way (other than
json:{} pseudoprotocol) to force a backing file, but with -blockdev,
libvirt HAS to use blockdev-open on the backing chain and supply a
backing format there, and thus has to probe images. If libvirt ever
probes differently than qemu, we are back to the potential
guest-visible data corruption or potential host CVEs.
It's time to deprecate images without backing formats. This patch
series does two things: 1. record an implicit backing format where one
is learned (although sadly, not all qemu-img commands are able to
learn a format), 2. warn to the user any time a probe had ambiguous
results or a backing format is omitted from an image. All previous
images without a backing format are still usable, but hopefully the
warnings (along with libvirt's complaints about images without a
backing format) help us pinpoint remaining applications that are
creating images on their own without recording a backing format.
Perhaps I need to amend patch 3 and/or add a followup patch 4 that
adds further iotest coverage of all the new warnings (patch 1 touched
all the './check -qcow2' tests that were affected by the new warnings,
except for 114 which actually wanted to trigger the warning, if you
want to apply the series out of order to see the impact of the
warnings).

New subject: [PATCH 1/3] iotests: Specify explicit backing format where sensible
There are many existing qcow2 images that specify a backing file but
no format. This has been the source of CVEs in the past, but has
become more prominent of a problem now that libvirt has switched to
-blockdev. With older -drive, at least the probing was always done by
qemu (so the only risk of a changed format between successive boots of
a guest was if qemu was upgraded and probed differently). But with
newer -blockdev, libvirt must specify a format; if libvirt guesses raw
where the image was formatted, this results in data corruption visible
to the guest; conversely, if libvirt guesses qcow2 where qemu was
using raw, this can result in potential security holes, so modern
libvirt instead refuses to use images without explicit backing format.
The change in libvirt to reject images without explicit backing format
has pointed out that a number of tools have been far too reliant on
probing in the past. It's time to set a better example in our own
iotests of properly setting this parameter.
iotest calls to create, rebase, convert, and amend are all impacted to
some degree. It's a bit annoying that we are inconsistent on command
line - while all of those accept -o backing_file=...,backing_fmt=...,
the shortcuts are different: create and rebase have -b and -F, convert
has -B but no -F, and amend has no shortcuts.

New subject: [PATCH 3/3] qemu-img: Deprecate use of -b without -F
Creating an image that requires format probing of the backing image is
inherently unsafe (we've had several CVEs over the years based on
probes leaking information to the guest on a subsequent boot). If our
probing algorithm ever changes, or if other tools like libvirt
determine a different probe result than we do, then subsequent use of
that backing file under a different format will present corrupted data
to the guest. Start a deprecation clock so that future qemu-img can
refuse to create unsafe backing chains that would rely on probing.
However, there is one time where probing is safe: when we first create
an image, no guest has yet used the new image, so as long as we record
what we probed, all future uses of the image will see the same data -
so the code now records the probe results as if the user had passed
-F. When this happens, it is unconditionally safe to record a probe
of 'raw', but any other probe is still worth warning the user in case
our probe differed from their expectations. Similarly, if the backing
file name uses the json: psuedo-protocol, the backing name includes
the format.
iotest 114 specifically wants to create an unsafe image for later
amendment rather than defaulting to our new default of recording a
probed format, so it needs an update.

I disagree. If you are creating an overlay on top of an existing image
it's not safe to probe the format any more generally. (obviously you'd
have to trust the image and express the trust somehow)
The image may have been used in a VM as raw and that means that the VM
might have recorded a valid qcow2 header into it. Creating the overlay
with probing would legitimize this.
Let's assume we have a malicious image written by the guest but we
simulate it by:
$ qemu-img create -f qcow2 -F raw -b /etc/passwd /tmp/malicious
Formatting '/tmp/malicious', fmt=qcow2 size=2560 backing_file=/etc/passwd
backing_fmt=raw cluster_size=65536 lazy_refcounts=off refcount_bits=16
Now we want to create an overlay.
a) without this patchset:
$ qemu-img create -f qcow2 -b /tmp/malicious /tmp/pre-patch.qcow2
Formatting '/tmp/pre-patch.qcow2', fmt=qcow2 size=2560 backing_file=/tmp/malicious
cluster_size=65536 lazy_refcounts=off refcount_bits=16
$ qemu-img info /tmp/pre-patch.qcow2
image: /tmp/pre-patch.qcow2
file format: qcow2
virtual size: 2.5 KiB (2560 bytes)
disk size: 196 KiB
cluster_size: 65536
backing file: /tmp/malicious
Format specific information:
compat: 1.1
lazy refcounts: false
refcount bits: 16
corrupt: false
There's no 'backing file format'. When used by libvirt we'd not allow
the VM to touch the backing file of /tmp/malicious in pre-blockdev era
and in libvirt-6.0 we'd report an error right away.
b) Now with this patchset:
$ ./qemu-img create -f qcow2 -b /tmp/malicious /tmp/post-patch.qcow2
qemu-img: warning: Deprecated use of non-raw backing file without explicit backing format,

You now get a warning, but "backing file format" is now recorded in the
overlay. Now this is WAY worse than it was before. The overlay now
legitimizes the format recorded by the malicious guest which circumvents
libvirt's protections. The warning is very easy to miss, and if you run
it in scripts you might never get to see it. We can't allow that.
so the code now records the probe results as if the user had passed
-F. When this happens, it is unconditionally safe to record a probe
of 'raw', but any other probe is still worth warning the user in case
While it's safe I don't think it should be encouraged. IMO -F should be
made mandatory with -b.
our probe differed from their expectations. Similarly, if the
backing
file name uses the json: psuedo-protocol, the backing name includes
the format.
Not necessarily. The backing store string can be e.g.:
$ ./qemu-img create -f qcow1 -b
'json:{"driver":"file","filename":"/tmp/malicious"}'
/tmp/json.qcow2
Formatting '/tmp/json.qcow1', fmt=qcow2 size=197120
backing_file=json:{"driver":"file",,"filename":"/tmp/malicious"}
cluster_size=65536 lazy_refcounts=off refcount_bits=16
$ qemu-img info /tmp/json.qcow1

backing file:
json:{"driver":"file","filename":"/tmp/malicious"}
Format specific information:
compat: 0.1
lazy refcounts: false
refcount bits: 15
corrupt: false
Now this has the old semantics but we didn't even get the warning. But
at least the backing file format is not written into the overlay.
iotest 114 specifically wants to create an unsafe image for later
amendment rather than defaulting to our new default of recording a
probed format, so it needs an update.

I disagree. If you are creating an overlay on top of an existing image
it's not safe to probe the format any more generally. (obviously you'd
have to trust the image and express the trust somehow)
The image may have been used in a VM as raw and that means that the VM
might have recorded a valid qcow2 header into it. Creating the overlay
with probing would legitimize this.
Let's assume we have a malicious image written by the guest but we
simulate it by:
b) Now with this patchset:
$ ./qemu-img create -f qcow2 -b /tmp/malicious /tmp/post-patch.qcow2
qemu-img: warning: Deprecated use of non-raw backing file without explicit backing
format, using detected format of qcow2

Good point. I'll respin this series where v2 never writes the implicit
format except for a raw image (because probing raw is not only safe to
record, but also prevents the guest from ever changing that probe, and
the real risk we are interested in preventing is when a formerly raw
image later probes as non-raw).

While it's safe I don't think it should be encouraged. IMO -F should be
made mandatory with -b.
Making it mandatory will require the completion of the deprecation
period. For 5.0 and 5.1, the best we can do is the warning, but for 5.2
(assuming v2 of this series is acceptable), it WILL become a hard error.

Not necessarily. The backing store string can be e.g.:
$ ./qemu-img create -f qcow1 -b
'json:{"driver":"file","filename":"/tmp/malicious"}'
/tmp/json.qcow2
Formatting '/tmp/json.qcow1', fmt=qcow2 size=197120
backing_file=json:{"driver":"file",,"filename":"/tmp/malicious"}

Hmm. json:{"driver":"qcow2",...} encodes the format, but your
argument
is that json:{"driver":"file",...} encodes only the protocol but not
the
format. We want the warning when there is no format, but with json:, it
becomes harder to tell if a format is present or not. I'll have to
think about what to do in that case.

We must never write the detected format into the overlay. Not even when

mises the warning.
Point taken. v2 will address this differently.

record, but also prevents the guest from ever changing that probe, and the
real risk we are interested in preventing is when a formerly raw image later

For 5.0 and 5.1, the best we can do is the warning, but for 5.2 (assuming v2
of this series is acceptable), it WILL become a hard error.
Yes, that's fair. I just wanted to point out that the warning and later
error should be reported also if raw is probed. I'm okay with recording
raw into the overlay even now.

Whoops, yes.

Discussed in my other reply (it looks like I'll need to distinguish
between json: pointing to just a protocol as the backing layer, vs. the
more typical json: pointing to a format as the backing layer).

I agree that mis-probing format leads to data corruption though.
Your argument that there are other means at hand to prevent CVE when
probing does occur is valid, however, my point is that CVEs due to
probing were historically possible if the rest of the toolchain is not
careful. It is more of a burden-shifting problem: when qemu is not
preventing probing, then other applications like libvirt have to take on
extra measures to ensure libvirt does not have a CVE (the fact that we
haven't had any in a few years is a good sign that we are at least aware
of the problem and have worked hard to remain safe, even if it has
required duplicated effort across multiple tools); whereas if qemu takes
a hard-line stance on probing (which is the goal of the deprecation
introduced in this series), now qemu has ensured safety whether or not
the other layers also take measures to avoid any CVE.
