Dear Linux-NFS people, NFS has always had the root_squash option, to protect against a remote and possibly evil root. NFS should also protect all privileged, or at least all root-equivalent, UIDs and GIDs. Many UNIX distributions have root-equivalent GIDs, groups whose members could easily become root, some listed in http://bugs.debian.org/299007#219 . Currently, NFS has no ways to protect privileged UIDs and GIDs other than root himself. Such options should be implemented, to make NFS safer and more useful. As I understand it, the hold-up is not within NFS code, but with kernel interfaces not supporting lists of squashed entities. I am asking you to devise and implement such interfaces.
