David Howells 033a666ccb NFSD: Don't hold unrefcounted creds over call to nfsd_setuser() ... nfsd_open() gets an unrefcounted pointer to the current process's effective credentials at the top of the function, then calls nfsd_setuser() via fh_verify() - which may replace and destroy the current process's effective credentials - and then passes the unrefcounted pointer to dentry_open() - but the credentials may have been destroyed by this point. Instead, the value from current_cred() should be passed directly to dentry_open() as one of its arguments, rather than being cached in a variable. Possibly fh_verify() should return the creds to use. This is a regression introduced by 745ca2475a "CRED: Pass credentials through dentry_open()".
