jalberto commented 11 months ago

Issue Description

I cannot run a rootless podman container without the --privileged flag

Steps to reproduce the issue

podman run --rm fedora /bin/echo "hola"
no output
podman run --rm --privileged fedora /bin/echo "hola"
output: hola

Describe the results you received

$ podman run --rm --privileged fedora /bin/echo "hola"
$ hola

$ podman run --rm  fedora /bin/echo "hola"
$

Describe the results you expected

Both commands should work

Luap99 commented 11 months ago

Assuming this is a regression do you know which updates you did before is started happening?

rhatdan commented 11 months ago

Could you try sudo setenforce 0

And see if the issue goes away?

If so could you gather the AVCs

sudo ausearch -m avc -ts recent

jalberto commented 11 months ago

This seems to be the issue:

SELinux is preventing echo from read access on the file /usr/lib64/libc.so.6

but after running

/sbin/restorecon -v /usr/lib64/libc.so.6

doesn't work

edsantiago commented 11 months ago

I've sometimes had good luck with dnf reinstall container-selinux...

jalberto commented 11 months ago

it was not installed as podman dependency, still didn't fix the issue, podman system reset did the trick.

Thanks for the help!

I still wonder how it happened, as it is a fresh install and non data was moved over.

rhatdan commented 11 months ago

Reinstall selinux followed by a relabel of containers/storage.

restorecon -R -v $HOME/.local/share/containers
