Detailed Description

hostapd / IEEE 802.11 Management

Function Documentation

int ieee802_11_mgmt	(	struct hostapd_data *	hapd,
		const u8 *	buf,
		size_t	len,
		struct hostapd_frame_info *	fi
	)

process incoming IEEE 802.11 management frames

Parameters

hapd	hostapd BSS data structure (the BSS to which the management frame was sent to)
buf	management frame data (starting from IEEE 802.11 header)
len	length of frame data in octets
fi	meta data about received frame (signal level, etc.)

Process all incoming IEEE 802.11 management frames. This will be called for each frame received from the kernel driver through wlan::ap interface. In addition, it can be called to re-inserted pending frames (e.g., when using external RADIUS server as an MAC ACL).

void ieee802_11_mgmt_cb	(	struct hostapd_data *	hapd,
		const u8 *	buf,
		size_t	len,
		u16	stype,
		int	ok
	)

Process management frame TX status callback.

Parameters

hapd	hostapd BSS data structure (the BSS from which the management frame was sent from)
buf	management frame data (starting from IEEE 802.11 header)
len	length of frame data in octets
stype	management frame subtype from frame control field
ok	Whether the frame was ACK'ed
