[PATCH v5 for-5.0? 0/7] Tighten qemu-img rules on missing backing format
v4 was here: https://lists.gnu.org/archive/html/qemu-devel/2020-03/msg03775.html In v5: - fix 'qemu-img convert -B' to actually warn [Kashyap] - squash in followups - a couple more iotest improvements If we decide this is not 5.0 material, then patches 4 and 7 need a tweak to s/5.0/5.1/ as the start of the deprecation clock. Eric Blake (7): sheepdog: Add trivial backing_fmt support vmdk: Add trivial backing_fmt support qcow: Tolerate backing_fmt=, but warn on backing_fmt=raw qcow2: Deprecate use of qemu-img amend to change backing file iotests: Specify explicit backing format where sensible block: Add support to warn on backing file change without format qemu-img: Deprecate use of -b without -F docs/system/deprecated.rst | 32 ++++++++++++++++ docs/tools/qemu-img.rst | 4 ++ include/block/block.h | 4 +- block.c | 34 +++++++++++++++-- block/qcow.c | 16 +++++++- block/qcow2.c | 7 +++- block/sheepdog.c | 18 ++++++++- block/stream.c | 2 +- block/vmdk.c | 14 +++++++ blockdev.c | 3 +- qemu-img.c | 11 +++++- tests/qemu-iotests/017 | 2 +- tests/qemu-iotests/017.out | 2 +- tests/qemu-iotests/018 | 2 +- tests/qemu-iotests/018.out | 2 +- tests/qemu-iotests/019 | 5 ++- tests/qemu-iotests/019.out | 2 +- tests/qemu-iotests/020 | 4 +- tests/qemu-iotests/020.out | 4 +- tests/qemu-iotests/024 | 8 ++-- tests/qemu-iotests/024.out | 5 ++- tests/qemu-iotests/028 | 4 +- tests/qemu-iotests/028.out | 2 +- tests/qemu-iotests/030 | 26 +++++++++---- tests/qemu-iotests/034 | 2 +- tests/qemu-iotests/034.out | 2 +- tests/qemu-iotests/037 | 2 +- tests/qemu-iotests/037.out | 2 +- tests/qemu-iotests/038 | 2 +- tests/qemu-iotests/038.out | 2 +- tests/qemu-iotests/039 | 3 +- tests/qemu-iotests/039.out | 2 +- tests/qemu-iotests/040 | 47 ++++++++++++++++------- tests/qemu-iotests/041 | 37 ++++++++++++------ tests/qemu-iotests/042 | 4 +- tests/qemu-iotests/043 | 18 ++++----- tests/qemu-iotests/043.out | 16 +++++--- tests/qemu-iotests/046 | 2 +- tests/qemu-iotests/046.out | 2 +- tests/qemu-iotests/050 | 4 +- tests/qemu-iotests/050.out | 2 +- tests/qemu-iotests/051 | 2 +- tests/qemu-iotests/051.out | 2 +- tests/qemu-iotests/051.pc.out | 2 +- tests/qemu-iotests/056 | 3 +- tests/qemu-iotests/060 | 2 +- tests/qemu-iotests/060.out | 2 +- tests/qemu-iotests/061 | 10 ++--- tests/qemu-iotests/061.out | 11 +++--- tests/qemu-iotests/069 | 2 +- tests/qemu-iotests/069.out | 2 +- tests/qemu-iotests/073 | 2 +- tests/qemu-iotests/073.out | 2 +- tests/qemu-iotests/082 | 10 +++-- tests/qemu-iotests/082.out | 14 ++++--- tests/qemu-iotests/085 | 4 +- tests/qemu-iotests/085.out | 6 +-- tests/qemu-iotests/089 | 2 +- tests/qemu-iotests/089.out | 2 +- tests/qemu-iotests/095 | 4 +- tests/qemu-iotests/095.out | 4 +- tests/qemu-iotests/097 | 4 +- tests/qemu-iotests/097.out | 16 ++++---- tests/qemu-iotests/098 | 2 +- tests/qemu-iotests/098.out | 8 ++-- tests/qemu-iotests/110 | 4 +- tests/qemu-iotests/110.out | 4 +- tests/qemu-iotests/114 | 12 ++++++ tests/qemu-iotests/114.out | 9 +++++ tests/qemu-iotests/122 | 27 +++++++------ tests/qemu-iotests/122.out | 8 ++-- tests/qemu-iotests/126 | 4 +- tests/qemu-iotests/126.out | 4 +- tests/qemu-iotests/127 | 4 +- tests/qemu-iotests/127.out | 4 +- tests/qemu-iotests/129 | 3 +- tests/qemu-iotests/133 | 2 +- tests/qemu-iotests/133.out | 2 +- tests/qemu-iotests/139 | 2 +- tests/qemu-iotests/141 | 4 +- tests/qemu-iotests/141.out | 4 +- tests/qemu-iotests/142 | 2 +- tests/qemu-iotests/142.out | 2 +- tests/qemu-iotests/153 | 14 +++---- tests/qemu-iotests/153.out | 35 +++++++++-------- tests/qemu-iotests/154 | 42 ++++++++++---------- tests/qemu-iotests/154.out | 42 ++++++++++---------- tests/qemu-iotests/155 | 12 ++++-- tests/qemu-iotests/156 | 9 +++-- tests/qemu-iotests/156.out | 6 +-- tests/qemu-iotests/158 | 2 +- tests/qemu-iotests/158.out | 2 +- tests/qemu-iotests/161 | 8 ++-- tests/qemu-iotests/161.out | 8 ++-- tests/qemu-iotests/176 | 4 +- tests/qemu-iotests/176.out | 32 ++++++++-------- tests/qemu-iotests/177 | 2 +- tests/qemu-iotests/177.out | 2 +- tests/qemu-iotests/179 | 2 +- tests/qemu-iotests/179.out | 2 +- tests/qemu-iotests/189 | 2 +- tests/qemu-iotests/189.out | 2 +- tests/qemu-iotests/191 | 12 +++--- tests/qemu-iotests/191.out | 12 +++--- tests/qemu-iotests/195 | 6 +-- tests/qemu-iotests/195.out | 6 +-- tests/qemu-iotests/198 | 2 +- tests/qemu-iotests/198.out | 3 +- tests/qemu-iotests/204 | 2 +- tests/qemu-iotests/204.out | 2 +- tests/qemu-iotests/216 | 2 +- tests/qemu-iotests/224 | 4 +- tests/qemu-iotests/225 | 2 +- tests/qemu-iotests/225.out | 2 +- tests/qemu-iotests/228 | 5 ++- tests/qemu-iotests/245 | 3 +- tests/qemu-iotests/249 | 4 +- tests/qemu-iotests/249.out | 4 +- tests/qemu-iotests/252 | 2 +- tests/qemu-iotests/257 | 3 +- tests/qemu-iotests/267 | 4 +- tests/qemu-iotests/267.out | 6 +-- tests/qemu-iotests/270 | 2 +- tests/qemu-iotests/270.out | 2 +- tests/qemu-iotests/273 | 4 +- tests/qemu-iotests/273.out | 4 +- tests/qemu-iotests/279 | 4 +- tests/qemu-iotests/279.out | 4 +- tests/qemu-iotests/290 | 72 +++++++++++++++++++++++++++++++++++ tests/qemu-iotests/290.out | 45 ++++++++++++++++++++++ tests/qemu-iotests/group | 1 + 131 files changed, 683 insertions(+), 350 deletions(-) create mode 100755 tests/qemu-iotests/290 create mode 100644 tests/qemu-iotests/290.out -- 2.26.0.rc2

qcow has no space in the metadata to store a backing format, and there are existing qcow images backed both by raw or by other formats (usually qcow) images, reliant on probing to tell the difference. While we don't recommend the creation of new qcow images (as qcow2 is hands-down better), we can at least insist that if the user does request a specific format without using -u, then it must be non-raw (as a raw backing file that gets inadvertently edited into some other format can form a security hole); if the user does not request a specific format or lies when using -u, then the status quo of probing for the backing format remains intact (although an upcoming patch will warn when omitting a format request). Thus, when this series is complete, the only way to use a backing file for qcow without triggering a warning is when using -F if the backing file is non-raw to begin with. Note that this is only for QemuOpts usage; there is no change to the QAPI to allow a format through -blockdev. Add a new iotest 290 just for qcow, to demonstrate the new warning.

Somehow this feels backwards. Not specifying the backing file format at all isn't any safer than explicitly specifying raw. If there is a difference at all, I would say that explicitly specifying raw means that the user is aware what they are doing. So we would have more reason to warn against raw images if the backing format isn't specified at all because then the user might not be aware that they are using a backing file that probes as raw.

This test doesn't tell the difference between a warning and an error. In both cases, the image would look the same: Either because it was successfully created or because the old version is still there. Kevin

Somehow this feels backwards. Not specifying the backing file format at all isn't any safer than explicitly specifying raw.
If there is a difference at all, I would say that explicitly specifying raw means that the user is aware what they are doing. So we would have more reason to warn against raw images if the backing format isn't specified at all because then the user might not be aware that they are using a backing file that probes as raw.
Prior to this patch, -F does not work with qcow. And even with this patch, we still cannot store the explicit value of -F in the qcow file. Anything that does not use -F must continue to work for now (although it may now warn, and in fact must warn if we deprecate it), while anything explicit is free to fail (since it failed already), but could also be made to work (if letting it work is nicer than making it fail, and where "work" may still include a warning, although it's pointless to have something brand new that works but is deprecated out of the box). So the following is my summary of the two options we can choose between: Option 1, qcow backed by raw is more common than qcow backed by other, so we want: raw <- qcow, no -F: work without warning (but if backing file is edited, a future probe seeing non-raw would break image) raw <- qcow, with -F: work without warning (but if backing file is edited, a future probe seeing non-raw would break image) other <- qcow, no -F: works but issues a warning (but backing file will always probe correctly) other <- qcow, with -F: fails (we cannot honor the user's explicit request, because we would still have to probe) Option 2, qcow backed by other is more common than qcow backed by raw, so we want: raw <- qcow, no -F: works but issues a warning (using a raw backing file without explicit buy-in is risky) raw <- qcow, with -F: works but issues a warning (explicit buy-in will still require subsequent probing, and a backing file could change which would break image) other <- qcow, no -F: works without warning other <- qcow, with -F: works without warning (later probing will still see non-raw) It looks like you are leaning more towards option 1, while my patch leaned more towards option 2. Anyone else want to chime in with an opinion on which is safer vs. easier?

The commit message promises a warning. This is not a warning, but a hard error.
Once we decide which behavior we want, I'll make sure the commit message matches the behavior. Remember, for implicit images, we are starting a deprecation clock; for explicit images, it previously failed, so continuing to fail is still viable.

This test doesn't tell the difference between a warning and an error. In both cases, the image would look the same: Either because it was successfully created or because the old version is still there.
Indeed, I can make the test more robust. But more importantly, we need consensus on _what_ we want behavior to be, and write the test along those lines. -- Eric Blake, Principal Software Engineer Red Hat, Inc. +1-919-301-3226 Virtualization: qemu.org | libvirt.org

Actually, even for a backing file, I think bs->probed should be set, so the raw driver would return an I/O error if you write the magic of an image format to the first sector. We should just add a test case to verify this behaviour for backing files (e.g. in the context of a commit job). Of course, if you edit the backing file outside of QEMU, that's your problem.
other <- qcow, no -F: works without warning (we'll probe in future opens, but the probe will see the same file type and not corrupt user data) other <- qcow, with -F: a probe is attempted and must match, but otherwise works without warning (we'll still have to probe in future opens, but it's no worse than before)
This plan makes sense to me. Kevin
The use of 'qemu-img amend' to change qcow2 backing files is not tested very well. In particular, our implementation has a bug where if a new backing file is provided without a format, then the prior format is blindly reused, even if this results in data corruption, but this is not caught by iotests. There are also situations where amending other options needs access to the original backing file (for example, on a downgrade to a v2 image, knowing whether a v3 zero cluster must be allocated or may be left unallocated depends on knowing whether the backing file already reads as zero), but the command line does not have a nice way to tell us both the backing file to use for opening the image as well as the backing file to install after the operation is complete. Even if we do allow changing the backing file, it is redundant with the existing ability to change backing files via 'qemu-img rebase -u'. It is time to deprecate this support (leaving the existing behavior intact, even if it is buggy), and at a point in the future, require the use of only 'qemu-img rebase' for adjusting backing chain relations, saving 'qemu-img amend' for changes unrelated to the backing chain.

I think the original idea was that in BlockDriver, special interfaces like the ones used by qemu-img rebase could eventually go away if we have a single consistent interface to change image options, which is amend. So ideally, bdrv_change_backing_file() should become a wrapper around amend. I'm not even sure if the behaviour you mention should be considered a bug because amend is a low-level interface. But even if that's the case, it would be a matter of simply adding a check. Kevin
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, and convert 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, while convert has -B but no -F. (amend has no shortcuts, but the previous patch just deprecated the use of amend to change backing chains).

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, although these days tools like libvirt are aware of the issue enough to prevent the worst effects). However, 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. Most warnings are intentionally emitted from bdrv_img_create() in the block layer, but qemu-img convert uses bdrv_create() which cannot emit its own warning without causing spurious warnings on other code paths. In the end, all command-line image creation or backing file rewriting now performs a check. However, there is one time where probing is safe: if we probe raw, then it is safe to record that implicitly in the image (but we still warn, as it's better to teach the user to supply -F always than to make them guess when it is safe). 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. While touching it, expand it to cover all of the various warnings enabled by this patch. iotest 290 also shows a change to qcow messages; note that the fact that we now make a probed format of 'raw' explicit now results in a double warning, but no one should be creating new qcow images so it is not worth cleaning up.

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, although these days tools like libvirt are aware of the issue enough to prevent the worst effects). However, 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. Most warnings are intentionally emitted from bdrv_img_create() in the block layer, but qemu-img convert uses bdrv_create() which cannot emit its own warning without causing spurious warnings on other code paths. In the end, all command-line image creation or backing file rewriting now performs a check.
However, there is one time where probing is safe: if we probe raw, then it is safe to record that implicitly in the image (but we still warn, as it's better to teach the user to supply -F always than to make them guess when it is safe).
You're not stating it explicitly, but I guess the thing that you mean that is actually unsafe is if you have a raw image, always pass format=raw to QEMU (so the guest could write e.g. a qcow2 header), but then create a backing file without -F, so it will be probed. This is as bad as specifying format=raw only sometimes. I don't like the idea of responding to this by making raw images more convenient to use than actual image formats. How about we approach it the other way around: The troublemaker is raw, so let's require specifying raw explicitly, and record the probed format implicitly in other cases. This is a bit weaker in the immediate effect in that it doesn't protect you when you actually deal with a malicious image, but in normal use it will point out where your scripts or management software is too careless. The final result should be that management tools are fixed and you'll be safe, while manual users who can usually trust their guests aren't inconvenienced too much. Kevin

That is definitely better than just probing. In my opinion though the format should always be specified explicitly. No favorism of 'raw' or any other format. In libvirt we fill-in that the format of the image is 'raw' unless the user specifies something else rather than reporting an error. This causes continuous grief for users who forget to set the format. (one example is that if you create a fully-allocated qcow2 image but use it as raw and install your VM, you'll never notice until you want to use qcow2 features. Users usually notice once they try to create a sparse image though due to the size difference)

If we decide this is not 5.0 material, then patches 4 and 7 need a tweak to s/5.0/5.1/ as the start of the deprecation clock.
Ping. I've already made the 5.1 change in my local tree, does anyone want to review the rest of this series before I post a v6?
