Some of the terminology used in EAP state machine is referring to
EAPOL (IEEE 802.1X), but there is no strict requirement on the lower
layer being IEEE 802.1X if EAP module is built for other programs than
-%wpa_supplicant. These terms should be understood to refer to the
+wpa_supplicant. These terms should be understood to refer to the
lower layer as defined in RFC 4137.
\section adding_eap_methods Adding EAP methods
Each EAP method is implemented as a separate module, usually as one C
-file named eap_<name of the method>.c, e.g., eap_md5.c. All EAP
+file named eap_server_<name of the method>.c, e.g., \ref eap_server_md5.c. All EAP
methods use the same interface between the server state machine and
method specific functions. This allows new EAP methods to be added
without modifying the core EAP state machine implementation.
New EAP methods need to be registered by adding them into the build
(Makefile) and the EAP method registration list in the
-eap_server_register_methods() function of eap_methods.c. Each EAP
+\ref eap_server_register_methods() function of \ref eap_server_methods.c. Each EAP
method should use a build-time configuration option, e.g., EAP_TLS, in
order to make it possible to select which of the methods are included
in the build.
-EAP methods must implement the interface defined in eap_i.h. struct
-eap_method defines the needed function pointers that each EAP method
+EAP methods must implement the interface defined in \ref eap_i.h. struct
+\ref eap_method defines the needed function pointers that each EAP method
must provide. In addition, the EAP type and name are registered using
this structure. This interface is based on section 4.4 of RFC 4137.
It is recommended that the EAP methods would use generic helper
-functions, eap_msg_alloc() and eap_hdr_validate() when processing
+functions, \ref eap_msg_alloc() and \ref eap_hdr_validate() when processing
messages. This allows code sharing and can avoid missing some of the
needed validation steps for received packets. In addition, these
functions make it easier to change between expanded and legacy EAP
When adding an EAP method that uses a vendor specific EAP type
(Expanded Type as defined in RFC 3748, Chapter 5.7), the new method
must be registered by passing vendor id instead of EAP_VENDOR_IETF to
-eap_server_method_alloc(). These methods must not try to emulate
+\ref eap_server_method_alloc(). These methods must not try to emulate
expanded types by registering a legacy EAP method for type 254. See
-eap_vendor_test.c for an example of an EAP method implementation that
+\ref eap_server_vendor_test.c for an example of an EAP method implementation that
is implemented as an expanded type.
