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(
char *mech,
rpc_gss_OID *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(3N)
manpage.
- 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.
MULTITHREAD USAGE
- Thread Safe:
Yes
- Cancel Safe:
Yes
- Fork Safe:
No
- Async-cancel Safe:
No
- Async-signal Safe:
No
These functions can be called safely in a multithreaded environment.
They may be cancellation points in that they call functions that are
cancel points.
In a multithreaded environment, these functions are
not safe to be called by a child process after
fork()
and before
exec().
These functions should not be called by a multithreaded application
that supports asynchronous cancellation or asynchronous signals.
RETURN VALUE
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.
