Dai Ngo c17a316f3d nfsd: nfsd4_setclientid_confirm mistakenly expires confirmed client.
commit ab451ea952fe9d7afefae55ddb28943a148247fe upstream.

From RFC 7530 Section 16.34.5:

o  The server has not recorded an unconfirmed { v, x, c, *, * } and
   has recorded a confirmed { v, x, c, *, s }.  If the principals of
   the record and of SETCLIENTID_CONFIRM do not match, the server
   returns NFS4ERR_CLID_INUSE without removing any relevant leased
   client state, and without changing recorded callback and
   callback_ident values for client { x }.

The current code intends to do what the spec describes above but
it forgot to set 'old' to NULL resulting to the confirmed client
to be expired.

Fixes: 2b63482185 ("nfsd: fix clid_inuse on mount with security change")

README

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
