Function Documentation

void ieee802_11_mgmt	(	struct hostapd_data *	hapd,
		u8 *	buf,
		size_t	len,
		u16	stype,
		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
	stype	management frame subtype from frame control field
	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).

Here is the call graph for this function:

void ieee802_11_mgmt_cb	(	struct hostapd_data *	hapd,
		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

Here is the call graph for this function:

void ieee802_11_send_deauth	(	struct hostapd_data *	hapd,
		u8 *	addr,
		u16	reason
	)

Send Deauthentication frame.

Parameters:

	hapd	hostapd BSS data
	addr	Address of the destination STA
	reason	Reason code for Deauthentication
