Function Documentation

void radius_msg_free

(

struct radius_msg *

msg

)

Free a RADIUS message.

Parameters:

msg	RADIUS message from radius_msg_new() or radius_msg_parse()

char* radius_msg_get_tunnel_password	(	struct radius_msg *	msg,
		int *	keylen,
		const u8 *	secret,
		size_t	secret_len,
		struct radius_msg *	sent_msg
	)

Parse RADIUS attribute Tunnel-Password.

Parameters:

msg	Received RADIUS message
keylen	Length of returned password
secret	RADIUS shared secret
secret_len	Length of secret
sent_msg	Sent RADIUS message

Returns:

pointer to password (free with os_free) or NULL

int radius_msg_get_vlanid

(

struct radius_msg *

msg

)

Parse RADIUS attributes for VLAN tunnel information.

Parameters:

msg	RADIUS message

Returns:

VLAN ID for the first tunnel configuration of -1 if none is found

struct radius_msg* radius_msg_new	(	u8	code,
		u8	identifier
	)		[read]

Create a new RADIUS message.

Parameters:

code	Code for RADIUS header
identifier	Identifier for RADIUS header

Returns:

Context for RADIUS message or NULL on failure

The caller is responsible for freeing the returned data with radius_msg_free().

struct radius_msg* radius_msg_parse	(	const u8 *	data,
		size_t	len
	)		[read]

Parse a RADIUS message.

Parameters:

data	RADIUS message to be parsed
len	Length of data buffer in octets

Returns:

Parsed RADIUS message or NULL on failure

This parses a RADIUS message and makes a copy of its data. The caller is responsible for freeing the returned data with radius_msg_free().
