rootfs not labeled with SELinux mount label

[bcressey]

In #1966 support was added for obtaining the process and mount labels on an SELinux-enabled system.

This works correctly for labeling the process, and for labeling most mounts. However, the new generateSecurityOpts() function is called from oci.GenerateSpec, which only happens after mounting the rootfs.

As a result, the root filesystem is not mounted with the expected mount label, and may not be writable by the container process, which ends up with a restricted label.

We first observed this in bottlerocket-os/bottlerocket#1187 but one of our developers saw a similar problem with a new Fedora install.

[bcressey]

This may be the root cause for #2295 as well - if the overlayfs is not mounted with a context= override, then the SELinux label will be the same as the underlying directory. If that's unlabeled_t then it may not be valid as an entry point into the container_t domain. With the mount label applied, it would be labeled as container_t and the transition would succeed.

I don't have a quick way to validate that hypothesis at the moment. Happy to have this resolved as a duplicate if it turns out to be the same problem.

Then execute:
restorecon -v '/bin/busybox'


*****  Plugin catchall (1.18 confidence) suggests   **************************

If you believe that runc:[2:INIT] should be allowed entrypoint access on the busybox file by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# ausearch -c 'runc:[2:INIT]' --raw | audit2allow -M my-runc2INIT
# semodule -X 300 -i my-runc2INIT.pp

Maybe the following will be helpful - I had a similar error when running buildkit 0.9.3 on RHEL 7/8. Fixed it by recompiling buildkit, explicitly adding selinux tag. (However, in my case I ran buildkit directly, without docker)

Fixed it by recompiling buildkit, explicitly adding selinux tag.

Could you explain exactly what you did?

[drdivano]

If you look into Dockerfile, there's a line like this:
ARG BUILDKITD_TAGS

You can pass the tag via the build argument BUILDKITD_TAGS="selinux" (or add tag "selinux" directly to go build --tags options in Dockerfile)

Same problem here with v0.10.1 and Fedora 37

[eriksjolund]

I asked the buildkit slack channel for advice and was told that my issue

• DOCKER_BUILDKIT=1 docker build fails on Fedora CoreOS 37.20230122.1.1 containers/container-selinux#201

is probably related to this issue.

I don't really have a machine readily available to test on.
I believe we can call label.Relabel after generating the spec using the mount label on the spec.
