Extended Generic Security Service Mechanism Inquiry APIs
Abstract
This document introduces new application programming interfaces
(APIs) to the Generic Security Services API (GSS-API) for extended
mechanism attribute inquiry. These interfaces are primarily intended
to reduce instances of hardcoding of mechanism identifiers in GSS
applications.
These interfaces include mechanism attributes and attribute sets, a
function for inquiring the attributes of a mechanism, a function for
indicating mechanisms that possess given attributes, and a function
for displaying mechanism attributes.

1. Introduction
GSS-API [RFC2743] mechanisms have a number of properties that may be
of interest to applications. The lack of APIs for inquiring about
available mechanisms' properties has meant that many GSS-API
applications must hardcode mechanism Object Identifiers (OIDs).
Ongoing work may result in a variety of new GSS-API mechanisms.
Applications should not have to hardcode their OIDs.
For example, the Secure Shell version 2 (SSHv2) protocol [RFC4251]
supports the use of GSS-API mechanisms for authentication [RFC4462]
but explicitly prohibits the use of Simple and Protected GSS-API
Negotiation (SPNEGO) [RFC4178]. Future mechanisms that negotiate
mechanisms would have to be forbidden as well, but there is no way to
implement applications that inquire what mechanisms are available and
then programmatically exclude mechanisms "like SPNEGO".
2. Conventions Used in This Document
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
"SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
document are to be interpreted as described in [RFC2119].
Williams Standards Track [Page 2]
RFC 5587 Extended GSS Mech Inquiry July 2009
3. New GSS-API Interfaces
We introduce a new concept -- that of mechanism attributes. By
allowing applications to query the set of attributes associated with
individual mechanisms and to find out which mechanisms support a
given set of attributes, we allow applications to select mechanisms
based on their attributes without having to hardcode mechanism OIDs.
Section 3.1 describes the mechanism attributes concept. Sections
3.4.2, 3.4.3, and 3.4.4 describe three new interfaces that deal in
mechanisms and attribute sets:
o GSS_Indicate_mechs_by_attrs()
o GSS_Inquire_attrs_for_mech()
o GSS_Display_mech_attr()
3.1. Mechanism Attributes and Attribute Sets
An abstraction for the features provided by mechanisms and pseudo-
mechanisms is needed in order to facilitate the programmatic
selection of mechanisms. Pseudo-mechanisms are mechanisms that make
reference to other mechanisms in order to provide their services.
For example, SPNEGO is a pseudo-mechanism, for without other
mechanisms SPNEGO is useless.
Two data types are needed: one for individual mechanism attributes
and one for mechanism attribute sets. To simplify the mechanism
attribute interfaces, we reuse the 'OID' and 'OID set' data types and
model individual mechanism attribute types as OIDs.
To this end, we define an open namespace of mechanism attributes and
assign them arcs off of this OID:
<1.3.6.1.5.5.13>
Each mechanism has a set of mechanism attributes that it supports as
described in its specification.

3.3. Mechanism Attribute Sets of Existing Mechs
The Kerberos V mechanism [RFC1964] provides the following mechanism
attributes:
o GSS_C_MA_MECH_CONCRETE
o GSS_C_MA_ITOK_FRAMED
o GSS_C_MA_AUTH_INIT
o GSS_C_MA_AUTH_TARG
o GSS_C_MA_DELEG_CRED
o GSS_C_MA_INTEG_PROT
o GSS_C_MA_CONF_PROT
Williams Standards Track [Page 6]
RFC 5587 Extended GSS Mech Inquiry July 2009
o GSS_C_MA_MIC
o GSS_C_MA_WRAP
o GSS_C_MA_PROT_READY
o GSS_C_MA_REPLAY_DET
o GSS_C_MA_OOS_DET
o GSS_C_MA_CBINDINGS
o GSS_C_MA_CTX_TRANS (some implementations, using implementation-
specific exported context token formats)
The Kerberos V mechanism also has a deprecated OID that has the same
mechanism attributes as above as well as GSS_C_MA_DEPRECATED.
The mechanism attributes of the Simple Public-Key GSS-API Mechanism
(SPKM) [RFC2025] family of mechanisms will be provided in a separate
document, as SPKM is currently being reviewed for possibly
significant changes due to problems in its specifications.
The Low Infrastructure Public Key (LIPKEY) mechanism [RFC2847] offers
the following attributes:
o GSS_C_MA_MECH_CONCRETE
o GSS_C_MA_ITOK_FRAMED
o GSS_C_MA_AUTH_INIT_INIT
o GSS_C_MA_AUTH_TARG (from SPKM-3)
o GSS_C_MA_AUTH_TARG_ANON (from SPKM-3)
o GSS_C_MA_INTEG_PROT
o GSS_C_MA_CONF_PROT
o GSS_C_MA_REPLAY_DET
o GSS_C_MA_OOS_DET
o GSS_C_MA_CTX_TRANS (some implementations, using implementation-
specific exported context token formats)
Williams Standards Track [Page 7]
RFC 5587 Extended GSS Mech Inquiry July 2009
(LIPKEY should also provide GSS_C_MA_CBINDINGS, but SPKM-3
requires clarifications on this point.)
The SPNEGO mechanism [RFC4178] provides the following attributes:
o GSS_C_MA_MECH_NEGO
o GSS_C_MA_ITOK_FRAMED
All other mechanisms' attributes will be described elsewhere.
3.4. New GSS-API Function Interfaces
Several new interfaces are given by which, for example, GSS-API
applications may determine what features are provided by a given
mechanism and what mechanisms provide what features.
These new interfaces are all OPTIONAL.
Applications should use GSS_Indicate_mechs_by_attrs() instead of
GSS_Indicate_mechs() wherever possible.
Applications can use GSS_Indicate_mechs_by_attrs() to determine what,
if any, mechanisms provide a given set of features.
GSS_Indicate_mechs_by_attrs() can also be used to indicate (as in
GSS_Indicate_mechs()) the set of available mechanisms of each type
(concrete, mechanism negotiation pseudo-mechanism, etc.).
3.4.1. Mechanism Attribute Criticality
Mechanism attributes may be added at any time. Not only may
attributes be added to the list of known mechanism attributes at any
time, but the set of mechanism attributes supported by a mechanism
can be changed at any time.
For example, new attributes might be added to reflect whether a
mechanism's initiator must contact an online infrastructure and/or
whether the acceptor must do so. In this example, the Kerberos V
mechanism would gain a new attribute even though the mechanism itself
is not modified.
Applications making use of attributes not defined herein would then
have no way of knowing whether a GSS-API implementation and its
mechanisms know about new mechanism attributes. To address this
problem, GSS_Indicate_mechs_by_attrs() and
GSS_Inquire_attrs_for_mech() support a notion of critical mechanism
attributes. Applications can search for mechanisms that understand
Williams Standards Track [Page 8]
RFC 5587 Extended GSS Mech Inquiry July 2009
mechanism attributes that are critical to the application, and the
application may ask what mechanism attributes are understood by a
given mechanism.
3.4.2. GSS_Indicate_mechs_by_attrs()
Inputs:
o desired_mech_attrs SET OF OBJECT IDENTIFIER -- set of GSS_C_MA_*
OIDs that the mechanisms indicated in the mechs output parameter
MUST offer.
o except_mech_attrs SET OF OBJECT IDENTIFIER -- set of GSS_C_MA_*
OIDs that the mechanisms indicated in the mechs output parameter
MUST NOT offer.
o critical_mech_attrs SET OF OBJECT IDENTIFIER -- set of GSS_C_MA_*
OIDs that the mechanisms indicated in the mechs output parameter
MUST understand (i.e., mechs must know whether critical attributes
are or are not supported).
Outputs:
o major_status INTEGER
o minor_status INTEGER
o mechs SET OF OBJECT IDENTIFIER -- set of mechanisms that support
the given desired_mech_attrs but not the except_mech_attrs, and
all of which understand the given critical_mech_attrs (the caller
must release this output with GSS_Release_oid_set()).
Return major_status codes:
o GSS_S_COMPLETE indicates success; the output mechs parameter MAY
be the empty set (GSS_C_NO_OID_SET).
o GSS_S_FAILURE indicates that the request failed for some other
reason.
GSS_Indicate_mechs_by_attrs() returns the set of OIDs corresponding
to mechanisms that offer at least the desired_mech_attrs but none of
the except_mech_attrs, and that understand all of the attributes
listed in critical_mech_attrs.
When all three sets of OID input parameters are the empty set, this
function acts as a version of GSS_indicate_mechs() that outputs the
set of all supported mechanisms.
Williams Standards Track [Page 9]
RFC 5587 Extended GSS Mech Inquiry July 2009
3.4.3. GSS_Inquire_attrs_for_mech()
Inputs:
o mech OBJECT IDENTIFIER -- mechanism OID
Outputs:
o major_status INTEGER
o minor_status INTEGER
o mech_attrs SET OF OBJECT IDENTIFIER -- set of mech_attrs OIDs
(GSS_C_MA_*) supported by the mechanism (the caller must release
this output with GSS_Release_oid_set()).
o known_mech_attrs SET OF OBJECT IDENTIFIER -- set of mech_attrs
OIDs known to the mechanism implementation (the caller must
release this output with GSS_Release_oid_set()).
Return major_status codes:
o GSS_S_COMPLETE indicates success; the output mech_attrs parameter
MAY be the empty set (GSS_C_NO_OID_SET).
o GSS_S_BAD_MECH indicates that the mechanism named by the mech
parameter does not exist or that the mech is GSS_C_NO_OID and no
default mechanism could be determined.
o GSS_S_FAILURE indicates that the request failed for some other
reason.
GSS_Inquire_attrs_for_mech() indicates the set of mechanism
attributes supported by a given mechanism.
3.4.4. GSS_Display_mech_attr()
Inputs:
o mech_attr OBJECT IDENTIFIER -- mechanism attribute OID
Outputs:
o major_status INTEGER
o minor_status INTEGER
Williams Standards Track [Page 10]
RFC 5587 Extended GSS Mech Inquiry July 2009
o name OCTET STRING, -- name of mechanism attribute (e.g.,
GSS_C_MA_*).
o short_desc OCTET STRING, -- a short description of the mechanism
attribute (the caller must release this output with
GSS_Release_buffer()).
o long_desc OCTET STRING -- a longer description of the mechanism
attribute (the caller must release this output with
GSS_Release_buffer()).
Return major_status codes:
o GSS_S_COMPLETE indicates success.
o GSS_S_BAD_MECH_ATTR indicates that the mechanism attribute
referenced by the mech_attr parameter is unknown to the
implementation.
o GSS_S_FAILURE indicates that the request failed for some other
reason.
This function can be used to obtain human-readable descriptions of
GSS-API mechanism attributes.
3.4.5. New Major Status Values
A single, new, major status code is added for
GSS_Display_mech_attr():
o GSS_S_BAD_MECH_ATTR,
roughly corresponding to GSS_S_BAD_MECH but applicable to mechanism
attribute OIDs rather than to mechanism OIDs.
For the C-bindings of the GSS-API [RFC2744], GSS_S_BAD_MECH_ATTR
shall have a routine error number of 19 (this is shifted to the left
by GSS_C_ROUTINE_ERROR_OFFSET).
3.4.6. C-Bindings
Note that there is a bug in the C bindings of the GSS-APIv2u1
[RFC2744] in that the C 'const' attribute is applied to types that
are pointer typedefs. This is a bug because it declares that the
pointer argument is 'const' rather than that the object pointed by it
is const. To avoid this error, we hereby define new typedefs, which
include const properly:
Williams Standards Track [Page 11]
RFC 5587 Extended GSS Mech Inquiry July 2009
typedef const gss_buffer_desc * gss_const_buffer_t;
typedef const struct gss_channel_bindings_struct *
gss_const_channel_bindings_t;
typedef const <platform-specific> gss_const_ctx_id_t;
typedef const <platform-specific> gss_const_cred_id_t;
typedef const <platform-specific> gss_const_name_t;
typedef const gss_OID_desc * gss_const_OID;
typedef const gss_OID_set_desc * gss_const_OID_set;
Figure 1: const typedefs
Note that only gss_const_OID and gss_const_OID_set are used below.
We include the other const typedefs for convenience since the C
bindings of the GSS-API do use const with pointer typedefs when it
should often instead use the above typedefs instead.
#define GSS_S_BAD_MECH_ATTR (19ul << GSS_C_ROUTINE_ERROR_OFFSET)
OM_uint32 gss_indicate_mechs_by_attrs(
OM_uint32 *minor_status,
gss_const_OID_set desired_mech_attrs,
gss_const_OID_set except_mech_attrs,
gss_const_OID_set critical_mech_attrs,
gss_OID_set *mechs);
OM_uint32 gss_inquire_attrs_for_mech(
OM_uint32 *minor_status,

4. Requirements for Mechanism Designers
All future GSS-API mechanism specifications MUST:
o list the set of GSS-API mechanism attributes associated with them.
5. IANA Considerations
The namespace of programming-language symbols with names beginning
with GSS_C_MA_* is reserved for allocation by IETF Consensus. IANA
allocated a base OID, as an arc of 1.3.6.1.5.5, for the set of
GSS_C_MA_* described herein, and registered all of the GSS_C_MA_*
values described in Section 3.2.
6. Security Considerations
This document specifies extensions to a security-related API. It
imposes new requirements on future GSS-API mechanisms, and the
specifications of future protocols that use the GSS-API should make
reference to this document where applicable. The ability to inquire
about specific properties of mechanisms should improve security.
The semantics of each mechanism attribute may include a security
component.
Application developers must understand that mechanism attributes may
be added at any time -- both to the set of known mechanism attributes
as well as to existing mechanisms' sets of supported mechanism
attributes. Therefore, application developers using the APIs
described herein must understand what mechanism attributes their
applications depend critically on, and must use the mechanism
attribute criticality features of these APIs.
