Subject: [PATCH 01/11] Do not skip records with nonblocking connections

With non-blocking connections, do not skip records when receiving
the streams since entire value messages can be ignored which
in cause the entire stream to become out of sync.

For example, two mounts simultaneously send two unmaps
commands. The first one is read, then the second thrown
away due to skipping the record. Skipping this record
will cause XDR error later in processing of the stream.

Subject: [PATCH 02/11] PCSEC_GSS_SVC_PRIVACY failure.

in authgss_prot.c:xdr_rpc_gss_wrap_data(), gss_wrap() is called in the
svc == RPCSEC_GSS_SVC_PRIVACY conditional block with databuf.length
uninitialized.

Initialization performed in the svc == RPCSEC_GSS_SVC_INTEGRITY
conditional block should be moved.

Subject: [PATCH 03/11] Use of lseek() in	xdr_rec.c:xdrrec_getpos().

The use of lseek() in xdr_rec.c:xdrrec_getpos() without checking for
ESPIPE will fail to handle the common case, resulting in poor behavior
in calling code. (In particular auth_gss.c:authgss_marshal() calls
gss_get_mic() with rpcbuf.length set to -1, with spectacular results.)

The original MIT Krb5 RPC code lacks this addition, which I'm unclear of
the utility of in the first place.

Reverting to the MIT code permits correct function of a trivial RPC
client using GSS.

Subject: [PATCH 06/11] auth_null used when auth_none is appropriate

svc_auth.c uses a fake entry function for AUTH_NULL (AUTH_NONE) when the
use of the svc_auth_none is appropriate.

With the previous patches to make use of WRAP/UNWRAP svc_auth_none is
required.

Subject: [PATCH 07/11] Reference count AUTHs

RPCSEC GSSv3 has the concept of a parent and a compound credential.  As
the normal course of operation involves using multiple AUTHs per client
connection, and providing parent and compounds AUTHs when creating a
GSSv3 AUTH, we need a way of reference counting them so that
AUTH_DESTROY does not free them out from under a GSSv3 AUTH that is
using them.

Subject: [PATCH 08/11] Use correct AUTH when calling RPCSEC_GSS_DESTROY.

When using multiple AUTHs per client connection, calling
AUTH_DESTROY(auth) may result in 'cl_auth' being set to something other
than 'auth'.

Avoid this by saving and restoring 'cl_auth' across the
RPCSEC_GSS_DESTROY clnt_call().

Subject: [PATCH 10/11] Revert "Include des_crypt in build"

The des_crypt code requires the crypt_client code (which wasn't
added), and that code requires a currently undefined function
(namely xdr_desresp).  Since I have no idea what that's about,
and this change ends up breaking some systems, just revert it.

Once we have a patch that improves portability without breaking
existing systems, we can revisit this.

This reverts commit 9bdcba10aa67ce3f67810c7aaac944a00dcfcee5.
