Upgrade to Version 4.34.0 with VirtioFS breaks file permissions again

[joville]

Description

We had the issue that a team member was not able to run composer install in a docker container without any git dubious ownership errors in some composer packages.

I was trying to reproduce the issue and could not find any issue at first until I saw that there is a docker.app upgrade from version 4.33.0 to 4.34.0. Finally I could reproduce the issue. I was downgrading docker to 4.33.0 again for reproducing the previous state. It was running fine, but not with 4.34.0. After checking the issues I found the issues about permission issues with virtioFS. I tried the upgrade again with version 4.34.0 and switched the file sharing settings from VirtioFS to gRPC FUSE and it was working as expected.

Reproduce

1. Upgrade Docker.app to 4.34.0 and restart app (file sharing is set to VirtioFS in docker)
2. In a docker stack with a composer.json with some git based packages delete the vendor directory.
3. Run docker compose exec containername bash to get into the container console
4. Run composer install
5. You will get some of the following errors while installing a some composer packages: Install of any/package failed
   The cloning process into a directory will fail with this error summary: fatal: detected dubious ownership in repository at 'install target directory'

Expected behavior

Install process with composer install run without any (permission) errors.

Hm.. wondering if this is related to CVE-2024-32004 - the fix for that introduced an error message about "dubious ownership"; git/git@f4aa8c8

[thegass]

Looks like VirtioFS was broken on purpose to sell the new subscription only filesharing.
downgrading to 4.33 fixed misc. filesharing related issues.

[florianPat]

Still an issue on 4.34.3.
Steps I executed to reproduce this issue: The issue is that git directories created are owned by root and not by "you".

Also tested with 4.33.0 now, and works as expected with VirtioFS enabled. Will stick to this version till its resolved in 4.34

no high hopes that this will get fixed.

The issue seems to be solved with DockerDesktop 4.35.0 released yesterday.

Hi, If you're still encountering this issue could you try again with the latest 4.35.1? Also it's worth looking in settings and trying it with both virtualisation.framework and Docker VMM (Settings -> General -> Virtual Machine Options) since they have subtle file ownership differences.

Let me know what happens!
