Subject: NFS4 RPCGSS state protection (SP4_MACH_CRED) is not handled

Hello linux-nfs,

We have the following NFS4 test (implemented using pynfs framework,
not regular NFS4 client):
1. NFS4 client wants to use RPCGSS (Kerberos) and starts NFS4 traffic
with NFS4 NULL request to establish RPCGSS context of a machine
account.
2. During EXCHANGE_ID operation (client establishment), client asks
for SP4_MACH_CRED state protection with
spo_must_enforce/spo_must_allow fields set to values that are usually
used by NFS4 clients (as defined by rfc5661).
3. CREATE_SESSION and RECLAIM_COMPLETE operations (required for NFS4
session) are also done with RPCGSS and sevice=svc_gss_integrity - as
required by spo_must_enforce option of state protection. If
CREATE_SESSION is done with the wrong protection type, error is
returned to the client (as expected).
4. However, when operations that are neither in spo_must_enforce nor
in spo_must_allow list are done with the wrong protection type
(flavor=AUTH_UNIX), NFS server accepts the request and replies by
unexpected result (NFS4_OK) instead of error. In our test we used
SEQUENCE + PUTROOTFH + GETFH compound operation with RPC credentials
using flavor=AUTH_UNIX instead of RPCGSS.

As for me, it looks like a security issue: client asked for state
protection but man-in-the-middle can make unprotected requests for
state-protected client and session. Expected behaviour from my side
is:
if NFS4 operation (like GETFH) from state-protected client is neither
in spo_must_enforce nor in spo_must_allow lists of SP4_MACH_CRED, the
server must fail the request if used credentials has a different
flavor than RPCGSS (neither user GSS context nor machine account GSS
context).

From rfc5661 (18.35.3.  DESCRIPTION):

   o  For SP4_MACH_CRED or SP4_SSV state protection:

      *  The list of operations (spo_must_enforce) that MUST use the
         specified state protection.  This list comes from the results
         of EXCHANGE_ID.

      *  The list of operations (spo_must_allow) that MAY use the
         specified state protection.  This list comes from the results
         of EXCHANGE_ID.

...

   o  SP4_MACH_CRED.  If spa_how is SP4_MACH_CRED, then the client MUST
      send the EXCHANGE_ID request with RPCSEC_GSS as the security
      flavor, and with a service of RPC_GSS_SVC_INTEGRITY or
      RPC_GSS_SVC_PRIVACY.  If SP4_MACH_CRED is specified, then the
      client wants to use an RPCSEC_GSS-based machine credential to
      protect its state.  The server MUST note the principal the
      EXCHANGE_ID operation was sent with, and the GSS mechanism used.
      These notes collectively comprise the machine credential.

Please see pcap file of the traffic (attached) - EXCHANGE_ID with
SP4_MACH_CRED is the packet #41 and problematic PUTROOTFH + GETFH
request is the packet #49.
