Problem 1:
- you're mounting things into the global namespace, but expect it only be visible to a certain subset of processes. these processes are also not specicified by a tradition unix session / process group / etc but against all the process attributes we have based on the uid
Problem 2, which is related:
- in fuse you're re-routing filesystem request to userspace, so fine so good - mount is currently a privilegued operation, and expects a privilegued filesystem implementation, not an ordinary user - to bypass that you have a suid mount wrapper - now you need various hacks to make sure this can't be used by other users
in short you are hacking around the namespace management which sits above the filesystems in a rather broken way. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
