Info

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 (Input) An enumerated type appropiate to the enumID. Authorities No authorization is required. Return Value gsk_attribute_set_enum() returns an integer. Possible values are: [GSK_OK] gsk_attribute_set_enum() was successful. [GSK_ATTRIBUTE_INVALID_ENUMERATION] The enumeration specified for the enumValue was not valid. [GSK_ATTRIBUTE_INVALID_ID] The enumID specified was not valid. [GSK_CONFLICTING_VALIDATION_SETTING] The value for GSK_SERVER_AUTH_TYPE or GSK_CLIENT_AUTH_TYPE conflicts with the setting for the validationCallBack.validateRequired field for GSK_CERT_VALIDATION_CALLBACK set by gsk_attribute_set_callback(). [GSK_INVALID_STATE] One of the following occurred: v The enumID cannot be set after a gsk_environment_init() has been issued. v The enumID cannot be set after a gsk_secure_soc_init() has been issued. [GSK_INVALID_HANDLE] The handle specified was 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_set_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. 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. 26 System i: Programming Secure Sockets APIs
Usage Notes 1. The following GSK_ENUM_ID values may be set in the SSL environment after gsk_environment_open() and before gsk_environment_init(). They are used as defaults for subsequent secure sessions: 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 set for each individual secure session after gsk_secure_soc_open() and before gsk_secure_soc_init(). These values will override values set in the SSL environment: 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 Related Information v “gsk_attribute_get_enum()—Get enumerated information about a secure session or an SSL environment” on page 10—Get enumerated information about a secure session or an SSL environment. v “gsk_attribute_set_buffer()—Set character information for a secure session or an SSL environment” on page 16—Set character string information for a secure session or an SSL environment. v “gsk_attribute_set_numeric_value()—Set numeric information for a secure session or an SSL environment” on page 28—Set numeric information for a secure session or an SSL environment v “gsk_environment_init()—Initialize an SSL environment” on page 32—Initialize an SSL environment v “gsk_environment_open()—Get a handle for an SSL environment” on page 34—Get a handle for an SSL environment v “gsk_secure_soc_init()—Negotiate a secure session” on page 38—Negotiate a secure session v “gsk_secure_soc_misc()—Perform miscellaneous functions for a secure session” on page 41—Perform miscellaneous functions for a secure session v “gsk_secure_soc_open()—Get a handle for a secure session” on page 44—Get a handle for a secure session v “gsk_strerror()—Retrieve GSKit runtime error message” on page 62—Retrieve GSK runtime error message API introduced: V5R1 Top | UNIX-Type APIs | APIs by category Secure Sockets APIs 27
