chmod chrome-sandbox: operation not permitted #62

What happened:

I just noticed a warning about chmod failing for chrome-sadnbox while digging into different issue. I'm not sure if it is a problem actually. It's happening since 14. November. All paths I got by grepping logs start with /opt/safing so I suppose that started after me switching from manuall installation to fedora package.

Hey @northys, thanks for the report.

This is a fix for electron on older kernels that don't support unprivileged USERNS_CLONE.

You can find the details here:
safing/portmaster@9751a52#diff-f839e53dfe3b32402a831af008948d464c0b056563b68230e8da21764df5a914R22-R55

This shouldn't fail though, but more, this shouldn't be executed as your kernel should have support for unprivileged USERNS_CLONE.

Hi @northys, could you share the output of sysctl kernel.unprivileged_userns_clone ?

Thanks for the output. Seems like there's no such file on your system. I just downloaded and installed a fedora locally to test that and I'm able to reproduce the issue. I will ping you once we have a proper patch available (we changed some stuff in the beta release channel but I fear that fix is incomplete).

So it turns out there just no easy way to reliably detect whether or not unprivileged user namespaces are enabled or not. Right now I see the following possibilities:

We could try to parse /proc/config.gz but that file is not always available. In that case, we would need to start searching the boot partition for config-<kver> files and try to parse them. Then we need to check if CONFIG_USER_NS and CONFIG_USER_NS_UNPRIVILEGED are enabled. Though the existence of those files is not guaranteed and this approach will likely fail.
To detect user namespaces we can check if /proc/self/ns/user exists but that does not tell us whether unprivileged (CONFIG_USER_NS_UNPRIVILEGED) is enabled as well.
We could try to run unshare --map-root-user id -u and check whether it executes successfully and outputs 0. Though, this adds a new dependency for the unshare binary and will likely require some tweaks/hacks for different verions of that binary.

To sum up, I'm not sure trying to correctly detect that is worth the effort. Maybe we can just set the SUID bit by default on chrome-sandbox and provide a flag to disable that behavior in case somebody really want's to avoid having an SUID binary lying around. That would be the best choice for user experience. Security wise, we could NOT set the SUID bit and rather try to inform the user that this needs to be done manually after an upgrade of electron. Though, communicating this is hard since the UI doesn't start and it might be hard to fix for less tech-savvy users.

My pitch would be to set the SUID bit and let users disable the behavior using a --disable-sandbox-suid flag.

Sorry for late reply I forgot about this issue. I actually don't understand the internals much and the log isn't bothering me since everything works. I just wanted to ask if everything is fine and whether I should care about the warning.

So it's up to you to figure out how to solve this issue. Someone would say to write it to doc but who reads the doc right? :D
