Detailed Description

EAP peer method: EAP-FAST PAC file processing.

Function Documentation

int eap_fast_add_pac	(	struct eap_fast_pac **	pac_root,
		struct eap_fast_pac **	pac_current,
		struct eap_fast_pac *	entry
	)

Add a copy of a PAC entry to a list.

Parameters

pac_root	Pointer to PAC list root pointer
pac_current	Pointer to the current PAC pointer
entry	New entry to clone and add to the list

Returns

0 on success, -1 on failure

This function makes a clone of the given PAC entry and adds this copied entry to the list (pac_root). If an old entry for the same A-ID is found, it will be removed from the PAC list and in this case, pac_current entry is set to NULL if it was the removed entry.

void eap_fast_free_pac

(

struct eap_fast_pac *

pac

)

Free PAC data.

Parameters

pac	Pointer to the PAC entry

Note that the PAC entry must not be in a list since this function does not remove the list links.

struct eap_fast_pac* eap_fast_get_pac	(	struct eap_fast_pac *	pac_root,
		const u8 *	a_id,
		size_t	a_id_len,
		u16	pac_type
	)

Get a PAC entry based on A-ID.

Parameters

pac_root	Pointer to root of the PAC list
a_id	A-ID to search for
a_id_len	Length of A-ID
pac_type	PAC-Type to search for

Returns

Pointer to the PAC entry, or NULL if A-ID not found

int eap_fast_load_pac	(	struct eap_sm *	sm,
		struct eap_fast_pac **	pac_root,
		const char *	pac_file
	)

Load PAC entries (text format)

Parameters

sm	Pointer to EAP state machine allocated with eap_peer_sm_init()
pac_root	Pointer to root of the PAC list (to be filled)
pac_file	Name of the PAC file/blob to load

Returns

0 on success, -1 on failure

int eap_fast_load_pac_bin	(	struct eap_sm *	sm,
		struct eap_fast_pac **	pac_root,
		const char *	pac_file
	)

Load PAC entries (binary format)

Parameters

sm	Pointer to EAP state machine allocated with eap_peer_sm_init()
pac_root	Pointer to root of the PAC list (to be filled)
pac_file	Name of the PAC file/blob to load

Returns

0 on success, -1 on failure

size_t eap_fast_pac_list_truncate	(	struct eap_fast_pac *	pac_root,
		size_t	max_len
	)

Truncate a PAC list to the given length.

Parameters

pac_root	Root of the PAC list
max_len	Maximum length of the list (>= 1)

Returns

Number of PAC entries removed

int eap_fast_save_pac	(	struct eap_sm *	sm,
		struct eap_fast_pac *	pac_root,
		const char *	pac_file
	)

Save PAC entries (text format)

Parameters

sm	Pointer to EAP state machine allocated with eap_peer_sm_init()
pac_root	Root of the PAC list
pac_file	Name of the PAC file/blob

Returns

0 on success, -1 on failure

int eap_fast_save_pac_bin	(	struct eap_sm *	sm,
		struct eap_fast_pac *	pac_root,
		const char *	pac_file
	)

Save PAC entries (binary format)

Parameters

sm	Pointer to EAP state machine allocated with eap_peer_sm_init()
pac_root	Root of the PAC list
pac_file	Name of the PAC file/blob

Returns

0 on success, -1 on failure
