- obtain information about a security context
cc [ flag... ] file... -lgss [ library... ] #include <gssapi/gssapi.h> OM_uint32 gss_inquire_context(OM_uint32 *minor_status, const gss_ctx_id_t context_handle,gss_name_t *src_name, gss_name_t *targ_name, OM_uint32 *lifetime_rec, gss_OID *mech_type, OM_uint32 *ctx_flags, int *locally_initiated, int *open);
The gss_inquire_context() function obtains information about a security context. The caller must already have obtained a handle that refers to the context, although the context need not be fully established.
The parameter descriptions for gss_inquire_context() are as follows:
A mechanism-specific status code.
A handle that refers to the security context.
The name of the context initiator. If the context was established using anonymous authentication, and if the application invoking gss_inquire_context() is the context acceptor, an anonymous name is returned. Storage associated with this name must be freed by the application after use with a call to gss_release_name(). Specify NULL if the parameter is not required.
The name of the context acceptor. Storage associated with this name must be freed by the application after use with a call to gss_release_name(). If the context acceptor did not authenticate itself, and if the initiator did not specify a target name in its call to gss_init_sec_context(), the value GSS_C_NO_NAME is returned. Specify NULL if the parameter is not required.
The number of seconds for which the context will remain valid. If the context has expired, this parameter will be set to zero. Specify NULL if the parameter is not required.
The security mechanism providing the context. The returned OID is a pointer to static storage that should be treated as read-only by the application; in particular, the application should not attempt to free it. Specify NULL if the parameter is not required.
Contains various independent flags, each of which indicates that the context supports (or is expected to support, if ctx_open is false) a specific service option. If not needed, specify NULL. Symbolic names are provided for each flag, and the symbolic names corresponding to the required flags should be logically ANDed with the ret_flags value to test whether a given option is supported by the context. The flags are:
If true, credentials were delegated from the initiator to the acceptor. If false, no credentials were delegated.
If true, the acceptor was authenticated to the initiator. If false, the acceptor did not authenticate itself.
If true, the replay of protected messages will be detected. If false, replayed messages will not be detected.
If true, out-of-sequence protected messages will be detected. If false, out-of-sequence messages will not be detected.
If true, confidential service may be invoked by calling the gss_wrap(3GSS) routine. If false, no confidential service is available through gss_wrap(). gss_wrap() provides message encapsulation, data-origin authentication, and integrity services only.
If true, integrity service can be invoked by calling either the gss_get_mic() or the gss_wrap() routine. If false, per-message integrity service is unavailable.
If true, the initiator's identity is not revealed to the acceptor. The src_name parameter, if requested, contains an anonymous internal name. If false, the initiator has been authenticated normally.
If true, the protection services, as specified by the states of the GSS_C_CONF_FLAG and GSS_C_INTEG_FLAG, are available for use. If false, they are available only if the context is fully established, that is, if the open parameter is non-zero.
If true, resultant security context can be transferred to other processes through a call to gss_export_sec_context(). If false, the security context is not transferable.
Non-zero if the invoking application is the context initiator. Specify NULL if the parameter is not required.
Non-zero if the context is fully established; zero if a context-establishment token is expected from the peer application. Specify NULL if the parameter is not required.
gss_inquire_context() returns one of the following status codes:
The referenced context could not be accessed.
The underlying mechanism detected an error for which no specific GSS status code is defined. The mechanism-specific status code reported by means of the minor_status parameter details the error condition.
