rpc_gss_mech_to_oid(3C)

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(3C) 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
