| |
Hi,
with NFS3, there is this 'root hole', i.e. any person who has a root account (perhaps by use of a laptop) can mount an export (let's say this export had the "root_squash" option), and still have a look at the user files, because he can locally setuid() into another user.
So I was looking for alternatives. CIFS is my favorite candidate, but it has a few issues right now. So does sshfs and about everything I have come across. Since I remember NFS4 can use KRB5 authentification, my question is, will the NFS(4) server process run with an fsuid equal to the user that authenticated?
