Info

secure session does not start, and an error code is returned from gsk_secure_soc_init(). Applications can detect the situation where the secure session started but validation failed by checking the GSK_CERTIFICATE_VALIDATION_CODE enumId via gsk_attribute_get_numeric value(). The numValue will indicate the certificate validation return code for server’s certificate. In this situation, the application is responsible for the authentication of the server. It is highly recommended that this option only be used if an alternate authentication method is used. v GSK_ENVIRONMENT_CLOSE_OPTIONS (411) - Type of special close options to use for this environment. If gsk_environment_close() is issued prior to all secure sessions being closed, the active secure sessions will continue to work and the environment close will effectively be delayed. The resources for the SSL environment will not be freed up until after the last secure session closes. No new secure sessions will be allowed to start using the closed SSL environment. enumValue must specify one of the following: – GSK_DELAYED_ENVIRONMENT_CLOSE (536) - Enable the environment close callback routine support. – GSK_NORMAL_ENVIRONMENT_CLOSE (537) - Field is ignored. enumValue (Output) Specifies a pointer to an integer in which to place the value of the requested information. Authorities No authorization is required. Return Value gsk_attribute_get_enum() returns an integer. Possible values are: [GSK_OK] gsk_attribute_get_enum() was successful. [GSK_ATTRIBUTE_INVALID_ID] The specified enumID was not valid. [GSK_INVALID_HANDLE] The specified handle was not valid. [GSK_AS400_ERROR_INVALID_POINTER] The enumValue pointer is not valid. [GSK_ERROR_UNSUPPORTED] The enumID is currently not supported. [GSK_ERROR_IO] An error occurred in SSL processing, check the errno value. Error Conditions When the gsk_attribute_get_enum() API fails with return code [GSK_ERROR_IO], errno can be set to: [EINTR] Interrupted function call. [EDEADLK] Resource deadlock avoided. [ETERM] Operation terminated. 12 System i: Programming Secure Sockets APIs
If an errno is returned that is not in this list, look in “Errno Values for UNIX-Type Functions” on page 103 for a description of the errno. Usage Notes 1. The following GSK_ENUM_ID values may be retrieved from the SSL environment after gsk_environment_open(). v GSK_PROTOCOL_SSLV2 v GSK_PROTOCOL_SSLV3 v GSK_PROTOCOL_TLSV1 v GSK_SESSION_TYPE v GSK_CLIENT_AUTH_TYPE v GSK_SERVER_AUTH_TYPE v GSK_ENVIRONMENT_CLOSE_OPTIONS 2. The following GSK_ENUM_ID values may be retrieved from the secure session after gsk_secure_soc_open(). v GSK_PROTOCOL_SSLV2 v GSK_PROTOCOL_SSLV3 v GSK_PROTOCOL_TLSV1 v GSK_PROTOCOL_USED v GSK_SESSION_TYPE v GSK_CLIENT_AUTH_TYPE v GSK_SID_FIRST v GSK_SERVER_AUTH_TYPE 3. The following GSK_ENUM_ID values are defaulted after gsk_secure_soc_open() and will be set for the secure session after gsk_secure_soc_init() or gsk_secure_soc_misc(). v GSK_PROTOCOL_USED v GSK_SID_FIRST Related Information v “gsk_attribute_get_buffer()—Get character information about a secure session or an SSL environment” on page 3 v “gsk_attribute_get_numeric_value()—Get numeric information about a secure session or an SSL environment” on page 14 v “gsk_attribute_get_cert_info()—Get information about a local or partner certificate” on page 6 v “gsk_attribute_set_enum()—Set enumerated information for a secure session or an SSL environment” on page 24 v “gsk_environment_close()—Close an SSL environment” on page 30 v “gsk_environment_init()—Initialize an SSL environment” on page 32 v “gsk_environment_open()—Get a handle for an SSL environment” on page 34 v “gsk_secure_soc_close()—Close a secure session” on page 37 v “gsk_secure_soc_init()—Negotiate a secure session” on page 38 v “gsk_secure_soc_misc()—Perform miscellaneous functions for a secure session” on page 41 v “gsk_secure_soc_open()—Get a handle for a secure session” on page 44 v “gsk_strerror()—Retrieve GSKit runtime error message” on page 62 Secure Sockets APIs 13
