RPC_GSS_MECH_TO_OID(3NSL) Networking Services Library Functions
NAME
rpc_gss_mech_to_oid, rpc_gss_qop_to_num - map mechanism, QOP strings to
non-string values
SYNOPSIS
#include <rpc/rpcsec_gss.h>
bool_t rpc_gss_mech_to_oid(
charc*mech,
rpc_gss_OIDc*oid);
bool_t rpc_gss_qop_to_num(
char *qop,
char *mech,
u_int *num);
DESCRIPTION
Because in-kernel RPC routines use non-string values for mechanism and
Quality of Protection (QOP), these routines exist to map strings for
these attributes to their non-string counterparts. (The non-string
values for QOP and mechanism are also found in the
/etc/gss/qop and
/etc/gss/mech files, respectively.)
rpc_gss_mech_to_oid() takes a string
representing a mechanism, as well as a pointer to a
rpc_gss_OID object
identifier structure. It then gives this structure values corresponding
to the indicated mechanism, so that the application can now use the OID
directly with RPC routines.
rpc_gss_qop_to_num() does much the same
thing, taking strings for QOP and mechanism and returning a number.
PARAMETERS
Information on
RPCSEC_GSS data types for parameters may be found on the
rpcsec_gss(3NSL) man page.
mech An ASCII string representing the security mechanism in use.
Valid strings may be found in the
/etc/gss/mech file.
oid An object identifier of type
rpc_gss_OID, whose elements are
usable by kernel-level RPC routines.
qop This is an ASCII string which sets the quality of protection
(QOP) for the session. Appropriate values for this string may be
found in the file
/etc/gss/qop.
num The non-string value for the QOP.
RETURN VALUES
Both functions return TRUE if they are successful, FALSE otherwise.
FILES
/etc/gss/mech File containing valid security mechanisms
/etc/gss/qop File containing valid QOP values
