NAME

gss_process_context_token —

Process a token on a security context from a peer application

SYNOPSIS

#include <gssapi/gssapi.h>

OM_uint32
gss_process_context_token(OM_uint32 *minor_status, const gss_ctx_id_t context_handle, const gss_buffer_t token_buffer);

DESCRIPTION

Provides a way to pass an asynchronous token to the security service. Most context-level tokens are emitted and processed synchronously by gss_init_sec_context() and gss_accept_sec_context(), and the application is informed as to whether further tokens are expected by the GSS_C_CONTINUE_NEEDED major status bit. Occasionally, a mechanism may need to emit a context-level token at a point when the peer entity is not expecting a token. For example, the initiator's final call to gss_init_sec_context() may emit a token and return a status of GSS_S_COMPLETE, but the acceptor's call to gss_accept_sec_context() may fail. The acceptor's mechanism may wish to send a token containing an error indication to the initiator, but the initiator is not expecting a token at this point, believing that the context is fully established. gss_process_context_token() provides a way to pass such a token to the mechanism at any time.

PARAMETERS

minor_status: Mechanism specific status code.
context_handle: Context handle of context on which token is to be processed.
token_buffer: Token to process.

RETURN VALUES

GSS_S_COMPLETE: Successful completion
GSS_S_DEFECTIVE_TOKEN: Indicates that consistency checks performed on the token failed
GSS_S_NO_CONTEXT: The context_handle did not refer to a valid context

STANDARDS

RFC 2743: Generic Security Service Application Program Interface Version 2, Update 1
