Function Documentation

libwifi_create_probe_req()

int libwifi_create_probe_req	(	struct libwifi_probe_req *	probe_req,
		const unsigned char	receiver[6],
		const unsigned char	transmitter[6],
		const unsigned char	address3[6],
		const char *	ssid,
		uint8_t	channel
	)

Generate a populated libwifi probe_req.

A generated libwifi probe_req can be "dumped" into a buffer for packet injection via the libwifi_dump_probe_req.

Parameters

probe_req	A libwifi_probe_req
receiver	The receiver MAC address, aka address 1
transmitter	The source MAC address, aka address 2
address3	The address 3 frame field value, typically the BSSID
ssid	The probe request SSID
channel	The probe request channel

Returns

Zero on success, or negative error

Generate a populated libwifi probe_req.

Two tagged parameters are also added to the beacon: SSID and Channel.

libwifi_dump_probe_req()

size_t libwifi_dump_probe_req	(	struct libwifi_probe_req *	probe_req,
		unsigned char *	buf,
		size_t	buf_len
	)

Dump a libwifi_probe_req into a raw format for packet injection.

Parameters

probe_req	A libwifi_probe_req
buf	The output buffer for the frame data
buf_len	The length of the output buffer

Returns

The length of the dumped probe_req, or negative error

Dump a libwifi_probe_req into a raw format for packet injection.

This is useful when injecting generated libwifi frames.
