* hw/arm/virt: Implement kvm-steal-timeAndrew Jones2020-10-081-0/+11
| | | | | | | | | | | We add the kvm-steal-time CPU property and implement it for machvirt. A tiny bit of refactoring was also done to allow pmu and pvtime to use the same vcpu device helper functions.

Make it clear that a feature deprecated in the Nth release is guaranteed to remain available in the N+1th release. Removal can occur in the N+2nd release or later. As an example of this in action, see commit 25956af3fe5dd0385ad8017bc768a6afe41e2a74 ("block: Finish deprecation of 'qemu-img convert -n -o'"). The feature was deprecated in QEMU 4.2.0.

Backslash-escapes may be necessary to prevent unintended parsing". The qemu(1) manual page (formatted with Sphinx 2.2.2) has several overlong lines on my system. A stand-alone backslash at EOL serves as line continuation in a "parsed-literal" block. Therefore, escape the backslashes that we want to appear as such in the formatted documentation.

| | | | | | | | | | | | | | | | | | | | Deprecate our lm32 target support. Michael Walle (former lm32 maintainer) suggested that we do this in 2019: https://www.mail-archive.com/qemu-devel@nongnu.org/msg605024.html because the only public user of the architecture is the many-years-dead milkymist project. (The Linux port to lm32 was never merged upstream.) In commit 4b4d96c776f552e (March 2020) we marked it as 'orphan' in the MAINTAINERS file, but didn't officially deprecate it.

* | qemu-img: Deprecate use of -b without -FEric Blake2020-07-141-0/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Creating an image that requires format probing of the backing image is potentially 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). For example, 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. Fortunately, the worst effects occur only when the backing image is originally raw, and we at least prevent commit into a probed raw backing file that would change its probed type. Still, it is worth starting a deprecation clock so that future qemu-img can refuse to create backing chains that would rely on probing, to encourage clients to avoid unsafe practices. 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. Furthermore, if we probe a backing file as non-raw, then it is safe to explicitly record that result (rather than relying on future probes); only where we probe a raw image do we care about further warnings to the user when using such an image (for example, commits into a probed-raw backing file are prevented), to help them improve their tooling. But whether or not we make the probe results explicit, we still warn the user to remind them to upgrade their workflow to supply -F always. 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 301 also shows a change to qcow messages.

* | qcow2: Deprecate use of qemu-img amend to change backing fileEric Blake2020-07-141-0/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* | block: Error if backing file fails during creation without -uEric Blake2020-07-141-0/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Back in commit 6e6e55f5 (Jul 2017, v2.10), we tweaked the code to warn if the backing file could not be opened but the user gave a size, unless the user also passes the -u option to bypass the open of the backing file. As one common reason for failure to open the backing file is when there is mismatch in the requested backing format in relation to what the backing file actually contains, we actually want to open the backing file and ensure that it has the right format in as many cases as possible. iotest 301 for qcow demonstrates how detecting explicit format mismatch is useful to prevent the creation of an image that would probe differently than the user requested. Now is the time to finally turn the warning an error, as promised. Note that the original warning was added prior to our documentation of an official deprecation policy (eb22aeca, also Jul 2017), and because the warning didn't mention the word "deprecated", we never actually remembered to document it as such. But the warning has been around long enough that I don't see prolonging it another two releases.
