Make request_key() and co. return an error for a negative or rejected key. If the key was simply negated, then return ENOKEY, otherwise return the error with which it was rejected. Without this patch, the following command returns a key number (with the latest keyutils): [root@andromeda ~]# keyctl request2 user debug:foo rejected @s 586569904 Trying to print the key merely gets you a permission denied error: [root@andromeda ~]# keyctl print 586569904 keyctl_read_alloc: Permission denied Doing another request_key() call does get you the error, as long as it hasn't expired yet: [root@andromeda ~]# keyctl request user debug:foo request_key: Key was rejected by service Signed-off-by: David Howells <dhowells@redhat.com> Signed-off-by: James Morris <jmorris@namei.org>
