struct eap_method - EAP method interface This structure defines the EAP method interface. Each method will need to register its own EAP type, EAP name, and set of function pointers for method specific operations. This interface is based on section 4.4 of RFC 4137.

| void(* eap_method::deinit)(struct eap_sm *sm, void *priv) |
deinit - Deinitialize an EAP method : Pointer to EAP state machine allocated with eap_peer_sm_init() : Pointer to private EAP method data from eap_method::init()
Deinitialize the EAP method and free any allocated private data.

| void(* eap_method::deinit_for_reauth)(struct eap_sm *sm, void *priv) |
deinit_for_reauth - Release data that is not needed for fast re-auth : Pointer to EAP state machine allocated with eap_peer_sm_init() : Pointer to private EAP method data from eap_method::init()
This function is an optional handler that only EAP methods supporting fast re-authentication need to implement. This is called when authentication has been completed and EAP state machine is requesting that enough state information is maintained for fast re-authentication

| void(* eap_method::free)(struct eap_method *method) |
free - Free EAP method data : Pointer to the method data registered with eap_peer_method_register().
This function will be called when the EAP method is being unregistered. If the EAP method allocated resources during registration (e.g., allocated struct eap_method), they should be freed in this function. No other method functions will be called after this call. If this function is not defined (i.e., function pointer is NULL), a default handler is used to release the method data with free(method). This is suitable for most cases.

get_status - Get EAP method status : Pointer to EAP state machine allocated with eap_peer_sm_init() : Pointer to private EAP method data from eap_method::init() : Buffer for status information : Maximum buffer length : Whether to include verbose status information Returns: Number of bytes written to buf
Query EAP method for status information. This function fills in a text area with current status information from the EAP method. If the buffer (buf) is not large enough, status information will be truncated to fit the buffer.

| u8 *(* eap_method::getKey)(struct eap_sm *sm, void *priv, size_t *len) |
getKey - Get EAP method specific keying material (eapKeyData) : Pointer to EAP state machine allocated with eap_peer_sm_init() : Pointer to private EAP method data from eap_method::init() : Pointer to variable to store key length (eapKeyDataLen) Returns: Keying material (eapKeyData) or NULL if not available
This function can be used to get the keying material from the EAP method. The key may already be stored in the method-specific private data or this function may derive the key.

| Boolean(* eap_method::has_reauth_data)(struct eap_sm *sm, void *priv) |
has_reauth_data - Whether method is ready for fast reauthentication : Pointer to EAP state machine allocated with eap_peer_sm_init() : Pointer to private EAP method data from eap_method::init() Returns: TRUE or FALSE based on whether fast reauthentication is possible
This function is an optional handler that only EAP methods supporting fast re-authentication need to implement.
Definition at line 173 of file eap_peer/eap_i.h.
| void *(* eap_method::init)(struct eap_sm *sm) |
init - Initialize an EAP method : Pointer to EAP state machine allocated with eap_peer_sm_init() Returns: Pointer to allocated private data, or NULL on failure
This function is used to initialize the EAP method explicitly instead of using METHOD_INIT state as specific in RFC 4137. The method is expected to initialize it method-specific state and return a pointer that will be used as the priv argument to other calls.
Definition at line 95 of file eap_peer/eap_i.h.
| void*(* eap_method::init_for_reauth)(struct eap_sm *sm, void *priv) |
init_for_reauth - Prepare for start of fast re-authentication : Pointer to EAP state machine allocated with eap_peer_sm_init() : Pointer to private EAP method data from eap_method::init()
This function is an optional handler that only EAP methods supporting fast re-authentication need to implement. This is called when EAP authentication is started and EAP state machine is requesting fast re-authentication to be used.

This function is a combination of m.check(), m.process(), and m.buildResp() procedures defined in section 4.4 of RFC 4137 In other words, this function validates the incoming request, processes it, and build a response packet. m.check() and m.process() return values are returned through struct eap_method_ret *ret variable. Caller is responsible for freeing the returned EAP response packet.

version - Version of the EAP peer method interface
The EAP peer method implementation should set this variable to EAP_PEER_METHOD_INTERFACE_VERSION. This is used to verify that the EAP method is using supported API version when using dynamically loadable EAP methods.

The EAP server method implementation should set this variable to EAP_SERVER_METHOD_INTERFACE_VERSION. This is used to verify that the EAP method is using supported API version when using dynamically loadable EAP methods.
