Function Documentation

◆ libwifi_create_reassoc_resp()

int libwifi_create_reassoc_resp ( struct libwifi_reassoc_resp reassoc_resp,
const unsigned char  receiver[6],
const unsigned char  transmitter[6],
const unsigned char  address3[6],
uint8_t  channel 
)

The generated reassoc_resp frame is made with sane defaults defined in common.h.

Generate a populated libwifi reassoc_resp.

One tagged parameters is also added to the reassoc_resp: Channel.

◆ libwifi_dump_reassoc_resp()

size_t libwifi_dump_reassoc_resp ( struct libwifi_reassoc_resp reassoc_resp,
unsigned char *  buf,
size_t  buf_len 
)

Copy a libwifi_reassoc_resp into a regular unsigned char buffer.

Dump a libwifi_reassoc_resp into a raw format for packet injection.

This is useful when injecting generated libwifi frames.

Definition at line 90 of file reassoc_response.c.

◆ libwifi_free_reassoc_resp()

void libwifi_free_reassoc_resp ( struct libwifi_reassoc_resp reassoc_resp)

Because the tagged parameters memory is managed inside of the library, the library must be the one to free it, too.

Free any memory claimed by a libwifi_reassoc_resp back to the system.

Definition at line 115 of file reassoc_response.c.

◆ libwifi_get_reassoc_resp_length()

size_t libwifi_get_reassoc_resp_length ( struct libwifi_reassoc_resp reassoc_resp)

The length of a reassociation response frame is the sum of the header length, the fixed parameters length, and the tagged parameters length.

Calculate the length of a given libwifi_reassoc_resp.

Definition at line 34 of file reassoc_response.c.

◆ libwifi_set_reassoc_resp_channel()

int libwifi_set_reassoc_resp_channel ( struct libwifi_reassoc_resp reassoc_resp,
uint8_t  channel 
)

Simple helper to set the reassociation response DS tag by removing it and then adding it back with the new value.

Set the channel of a libwifi_reassoc_resp.
