NAME

Callback Functions -

Typedefs


typedef int(* globus_gsi_extension_callback_t )(globus_gsi_callback_data_t callback_data, X509_EXTENSION *extension)
 

Get callback data index from X509_STORE


globus_result_t globus_gsi_callback_get_X509_STORE_callback_data_index (int *index)
 

Get callback data index from SSL structure


globus_result_t globus_gsi_callback_get_SSL_callback_data_index (int *index)
 

Certificate verify wrapper


int globus_gsi_callback_X509_verify_cert (X509_STORE_CTX *context, void *arg)
 

Independent path validation callback.


int globus_gsi_callback_create_proxy_callback (int preverify_ok, X509_STORE_CTX *x509_context)
 

SSL path validation callback.


int globus_gsi_callback_handshake_callback (int preverify_ok, X509_STORE_CTX *x509_context)
 

OpenSSL X509_check_issued() wrapper


int globus_gsi_callback_check_issued (X509_STORE_CTX *context, X509 *cert, X509 *issuer)
 

Detailed Description

Functions that plug into various plug points in the OpenSSL path validation mechanism.
 
These functions add CRL checking, X509 Extension handling and proxy validation.

Typedef Documentation

typedef int(* globus_gsi_extension_callback_t)(globus_gsi_callback_data_t callback_data, X509_EXTENSION *extension)

Typedef for a callback that may be registered for dealing with unhandled X.509 extension.

Function Documentation

globus_result_t globus_gsi_callback_get_X509_STORE_callback_data_index (int *index)

Retrieve or create the index for our callback data structure in the X509_STORE. Parameters:
index Will contain the index upon return
Returns:
GLOBUS_SUCCESS unless an error occurred, in which case, a globus error object ID is returned
 

globus_result_t globus_gsi_callback_get_SSL_callback_data_index (int *index)

Retrieve or create the index for our callback data structure in the SSL structure. Parameters:
index Will contain the index upon return
Returns:
GLOBUS_SUCCESS unless an error occurred, in which case, a globus error object ID is returned
 

int globus_gsi_callback_X509_verify_cert (X509_STORE_CTX *context, void *arg)

This function wraps the OpenSSL certificate verification callback for the purpose of a replacing the standard issuer check with one that deals with proxy certificates. Should be used with SSL_CTX_set_cert_verify_callback()
Parameters:
context The X509_STORE_CTX for which to register the callback.
 
arg Arguments to the callback. Currently ignored.
Returns:
1 on success 0 on failure
 

int globus_gsi_callback_create_proxy_callback (intpreverify_ok, X509_STORE_CTX *x509_context)

This function provides a path validation callback for validation outside of a SSL session. It should be used in X509_STORE_set_verify_cb_func().
Parameters:
preverify_ok Communicates the result of default validation steps performed by OpenSSL
 
x509_context The validation state object
Returns:
1 on success 0 on failure
 

int globus_gsi_callback_handshake_callback (intpreverify_ok, X509_STORE_CTX *x509_context)

This function provides a path validation callback for the validation part of establishing a SSL session. It handles proxy certificates, X509 Extensions and CRL checking. It should be used in SSL_CTX_set_verify().
Parameters:
preverify_ok Communicates the result of default validation steps performed by OpenSSL
 
x509_context The validation state object.
Returns:
1 on success 0 on failure
 

int globus_gsi_callback_check_issued (X509_STORE_CTX *context, X509 *cert, X509 *issuer)

This function wraps the OpenSSL X509_check_issued() call and catches the error caused by the fact that a proxy certificate issuer may not have to have the correct KeyUsage fields set. Parameters:
context The validation state object.
 
cert The certificate to check
 
issuer The issuer certificate to check
Returns:
1 on success 0 on failure
