GSS_PROCESS_CONTEXT_TOKEN(3) Programmer's Manual GSS_PROCESS_CONTEXT_TOKEN(3)
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 estab-
lished. 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
