Detailed Description

EFI EAP(Extended Authenticaton Protocol) Protocol Definition The EFI EAP Protocol is used to abstract the ability to configure and extend the EAP framework. The definitions in this file are defined in UEFI Specification 2.3.1B, which have not been verified by one implementation yet.

Typedef Documentation

typedef EFI_STATUS(EFIAPI * EFI_EAP_BUILD_RESPONSE_PACKET)(IN EFI_PORT_HANDLE PortNumber, IN UINT8 *RequestBuffer, IN UINTN RequestSize, IN UINT8 *Buffer, IN OUT UINTN *BufferSize)

One user provided EAP authentication method.

Build EAP response packet in response to the EAP request packet specified by (RequestBuffer, RequestSize).

Parameters

[in]	PortNumber	Specified the Port where the EAP request packet comes.
[in]	RequestBuffer	Pointer to the most recently received EAP- Request packet.
[in]	RequestSize	Packet size in bytes for the most recently received EAP-Request packet.
[in]	Buffer	Pointer to the buffer to hold the built packet.
[in,out]	BufferSize	Pointer to the buffer size in bytes. On input, it is the buffer size provided by the caller. On output, it is the buffer size in fact needed to contain the packet.

Return values

EFI_SUCCESS	The required EAP response packet is built successfully.
others	Failures are encountered during the packet building process.

typedef struct _EFI_EAP_PROTOCOL EFI_EAP_PROTOCOL

typedef EFI_STATUS(EFIAPI * EFI_EAP_REGISTER_AUTHENTICATION_METHOD)(IN EFI_EAP_PROTOCOL *This, IN UINT8 EapAuthType, IN EFI_EAP_BUILD_RESPONSE_PACKET Handler)

Register an EAP authentication method.

The RegisterAuthMethod() function registers the user provided EAP authentication method, the type of which is EapAuthType and the handler of which is Handler.

If EapAuthType is an invalid EAP authentication type, then EFI_INVALID_PARAMETER is returned. If there is not enough system memory to perform the registration, then EFI_OUT_OF_RESOURCES is returned.

Parameters

[in]	This	A pointer to the EFI_EAP_PROTOCOL instance that indicates the calling context.
[in]	EapAuthType	The type of the EAP authentication method to register. It should be the type value defined by RFC. See RFC 2284 for details.
[in]	Handler	The handler of the EAP authentication method to register.

Return values

EFI_SUCCESS	The EAP authentication method of EapAuthType is registered successfully.
EFI_INVALID_PARAMETER	EapAuthType is an invalid EAP authentication type.
EFI_OUT_OF_RESOURCES	There is not enough system memory to perform the registration.

typedef EFI_STATUS(EFIAPI * EFI_EAP_SET_DESIRED_AUTHENTICATION_METHOD)(IN EFI_EAP_PROTOCOL *This, IN UINT8 EapAuthType)

Set the desired EAP authentication method for the Port.

The SetDesiredAuthMethod() function sets the desired EAP authentication method indicated by EapAuthType for the Port.

If EapAuthType is an invalid EAP authentication type, then EFI_INVALID_PARAMETER is returned. If the EAP authentication method of EapAuthType is unsupported by the Ports, then it will return EFI_UNSUPPORTED. The cryptographic strength of EFI_EAP_TYPE_TLS shall be at least of hash strength SHA-256 and RSA key length of at least 2048 bits.

Parameters

[in]	This	A pointer to the EFI_EAP_PROTOCOL instance that indicates the calling context.
[in]	EapAuthType	The type of the EAP authentication method to register. It should be the type value defined by RFC. See RFC 2284 for details.
[in]	Handler	The handler of the EAP authentication method to register.

Return values

EFI_SUCCESS	The EAP authentication method of EapAuthType is registered successfully.
EFI_INVALID_PARAMETER	EapAuthType is an invalid EAP authentication type.
EFI_UNSUPPORTED	The EAP authentication method of EapAuthType is unsupported by the Port.

typedef VOID* EFI_PORT_HANDLE

Type for the identification number assigned to the Port by the System in which the Port resides.
