Function Documentation

void hostapd_acl_deinit

(

struct hostapd_data *

hapd

)

Deinitialize IEEE 802.11 ACL.

Parameters:

hapd	hostapd BSS data

int hostapd_acl_init

(

struct hostapd_data *

hapd

)

hostapd_acl_init: Initialize IEEE 802.11 ACL : hostapd BSS data Returns: 0 on success, -1 on failure

int hostapd_allowed_address	(	struct hostapd_data *	hapd,
		const u8 *	addr,
		const u8 *	msg,
		size_t	len,
		u32 *	session_timeout,
		u32 *	acct_interim_interval,
		int *	vlan_id,
		u8 *	psk,
		int *	has_psk
	)

Check whether a specified STA can be authenticated.

Parameters:

hapd	hostapd BSS data
addr	MAC address of the STA
msg	Authentication message
len	Length of msg in octets
session_timeout	Buffer for returning session timeout (from RADIUS)
acct_interim_interval	Buffer for returning account interval (from RADIUS)
vlan_id	Buffer for returning VLAN ID
psk	Buffer for returning WPA PSK
has_psk	Buffer for indicating whether psk was filled

Returns:

HOSTAPD_ACL_ACCEPT, HOSTAPD_ACL_REJECT, or HOSTAPD_ACL_PENDING
