Exception thrown on propietary driver about php-pkcs11

[gamringer]

When creating an object, the code looks for the object class (CKA_CLASS) in order to return the correct PHP object type:

Pkcs11\Key for the following:
CKO_PUBLIC_KEY
CKO_PRIVATE_KEY
CKO_SECRET_KEY
CKO_OTP_KEY

php-pkcs11/pkcs11session.c

Lines 584 to 592 in 14cb4e8

	if (classId == 2 || classId == 3 || classId == 4 || classId == 8) {
	pkcs11_key_object* key_obj;
	object_init_ex(retval, ce_Pkcs11_Key);
	key_obj = Z_PKCS11_KEY_P(retval);
	key_obj->session = objval;
	key_obj->key = hObject;
	GC_ADDREF(&objval->std);
	return rv;
	}

Pkcs11\Object for the the rest.

php-pkcs11/pkcs11session.c

Lines 596 to 602 in 14cb4e8

	object_init_ex(retval, ce_Pkcs11_P11Object);
	object_obj = Z_PKCS11_OBJECT_P(retval);
	object_obj->session = objval;
	object_obj->object = hObject;
	GC_ADDREF(&objval->std);
	return rv;

To do so, it calls into getObjectClass

php-pkcs11/pkcs11session.c

Line 582 in 14cb4e8

getObjectClass(objval, &hObject, &classId);

Inside getObjectClass, we get the CKA_CLASS, but it seems as though by that time, CK_OBJECT_HANDLE_PTR hObject that was passed as argument is no longer referencing the object that we just created.

php-pkcs11/pkcs11.c

Lines 177 to 191 in 14cb4e8

	CK_ATTRIBUTE template[] = {
	{CKA_CLASS, NULL_PTR, 0}
	};
	CK_RV rv;
	rv = session->pkcs11->functionList->C_GetAttributeValue(
	session->session,
	*hObject,
	template,
	1
	);
	if (rv != CKR_OK) {
	pkcs11_error(rv, "Unable to get attribute value");
	return;
	}
