@tonistiigi PTAL 🙏

@AkihiroSuda This is related to #120 (comment).

Looking at this comment #120 (comment), args[] is not tampered so this is smth to fix in direct exec patches to not prepend the workdir: 5da9dbf. So yeah direct without -P but this is not an issue with QEMU_PRESERVE_ARGV0, just changes needed in execve patches https://github.com/tonistiigi/binfmt/tree/master/patches/buildkit-direct-execve-v8.0
Probably https://github.com/tonistiigi/binfmt/blob/master/patches/buildkit-direct-execve-v8.0/0003-linux-user-path-in-execve-should-be-relative-to-work.patch

When fixed I think we can update latest.

What's the status on this?
It doesn't inspire confidence that the official setup-qemu-action Github action is pointing at a Docker image that hasn't been updated in over 2 years.

[tonistiigi]

We have versioned releases for the updated versions (eg. 8.1.5) . Latest tag has not been updated because there were some backwards incompatible changes as mentioned above that need to be fixed (additionally there is also some breakage in new qemu version for tini https://github.com/tonistiigi/binfmt/blob/master/patches/subreaper-prctl/0001-linux-user-pass-SUBREAPER-to-prctl.patch ). If you don't care about these upstream issues you can just use the versioned release directly.

We still want to update to the latest tag, but only if we can be certain that it doesn't cause many issues to existing users.

Hi @tonistiigi,

It's not especially clear which tags are appropriate to use with the setup-qemu-action Github action.
Is there any documentation that helps to provide clarity?

Thanks,
Jeremy

[tonistiigi]

@crazy-max Maybe we can add an example in the docs for using the 8.1.5 tag.

[norrisjeremy]

Is there any guidance yet as to which 8.1.5 tag is appropriate to use with the setup-qemu-action Github action?

[tonistiigi]

You can use either qemu-v8.1.5 or desktop-v8.1.5. The difference is that latter has some extra patches to maintain better backwards compatibility https://github.com/tonistiigi/binfmt/blob/master/docker-bake.hcl#L83

FYI, neither of these appear to be usable with Github Actions, as they result in segfaults:

63.80 Processing triggers for libc-bin (2.35-0ubuntu3.6) ...

64.18 Segmentation fault (core dumped)

64.19 Errors were encountered while processing:

This occurred simply executing apt-get dist-upgrade -y inside of an ubuntu:22.04 container.

@norrisjeremy Under GH codespaces seemed to work fine

@tonistiigi I started having issues similar to @norrisjeremy this past week, still using the default latest tag:

#6 [linux/arm64 2/9] RUN apt-get update     && apt-get install     -y -u --allow-downgrades     --no-install-recommends     kubectl-1.29     && apt-get clean     && rm -rf /var/lib/apt/lists/*

#6 1.620 Get:3 http://deb.debian.org/debian-security bookworm-security InRelease [48.0 kB]
#6 1.726 Reading package lists...
#6 6.549 E: Method https has died unexpectedly!
#6 6.549 E: Sub-process https received a segmentation fault.

Note that this is a multi-platform build: linux/amd64,linux/arm64

Only the cross-platform RUN step fails. If building on a linux/amd64 host, the linux/amd64 step succeeds and the linux/arm64 step fails. If building on a linux/arm64 host, the linux/arm64 step succeeds and the linux/amd64 step fails.

This seems to have been triggered by something in the GitHub Action Runner v2.381.0 release actions/actions-runner-controller#3684 which did not explicitly update anything, but pulled in the current versions of unpinned dependencies. Specifically, I am using what was built by this Dockerfile.

I'm still getting curl segfaults when reverting to an earlier build of 2.317, doesn't look like it's the root cause to me.

update: updating the K8S nodes from AL2 to AL2023 fixed it, along with matching the base image with the runner, eg. building an ubuntu20 on an ubuntu20 runner, or 22 on 22.

[jrjohnson]

IMHO it is much more confusing that latest isn't current than it would be for anyone experiencing a breaking change to pin their version to an earlier tag. If you're using latest you should expect updates to that tag to occasionally cause you problems you have to solve. I was pretty shocked to discover just how old latest was when I dug into it.

The current state of needing to use a specific version tag means I need to keep track of releases in this repo to know when I should update that string.
