Function Documentation

void wpa_driver_wext_deinit void *  priv  ) 
 

Deinitialize WE driver interface.

Parameters:
priv Pointer to private wext data from wpa_driver_wext_init()
Shut down driver interface and processing of driver events. Free private data buffer if one was allocated in wpa_driver_wext_init().

Here is the call graph for this function:

int wpa_driver_wext_get_bssid void *  priv,
u8 *  bssid
 

Get BSSID, SIOCGIWAP.

Parameters:
priv Pointer to private wext data from wpa_driver_wext_init()
bssid Buffer for BSSID
Returns:
0 on success, -1 on failure

Definition at line 164 of file driver_wext.c.

int wpa_driver_wext_get_ifflags struct wpa_driver_wext_data *  drv,
int *  flags
 

Get interface flags (SIOCGIFFLAGS).

Parameters:
drv driver_wext private data
flags Pointer to returned flags value
Returns:
0 on success, -1 on failure

Definition at line 819 of file driver_wext.c.

int wpa_driver_wext_get_scan_results void *  priv,
struct wpa_scan_result results,
size_t  max_size
 

Fetch the latest scan results.

Parameters:
priv Pointer to private wext data from wpa_driver_wext_init()
results Pointer to buffer for scan results
max_size Maximum number of entries (buffer size)

SSID length on success, -1 on failure

Definition at line 220 of file driver_wext.c.

void* wpa_driver_wext_init void *  ctx,
const char *  ifname
 

Initialize WE driver interface.

Parameters:
ctx context to be used when calling wpa_supplicant functions, e.g., wpa_supplicant_event()
ifname interface name, e.g., wlan0
Returns:
Pointer to private data, NULL on failure

Definition at line 862 of file driver_wext.c.

Here is the call graph for this function:

int wpa_driver_wext_scan void *  priv,
const u8 *  ssid,
size_t  ssid_len
 

Request the driver to initiate scan.

Parameters:

Scan timeout to report scan completion.

Parameters:
eloop_ctx Unused
timeout_ctx ctx argument given to wpa_driver_wext_init()
This function can be used as registered timeout when starting a scan to generate a scan completed event if the driver does not report this.

priv Private driver interface data
alg Encryption algorithm (WPA_ALG_NONE, WPA_ALG_WEP, WPA_ALG_TKIP, WPA_ALG_CCMP); WPA_ALG_NONE clears the key.
addr Address of the peer STA or ff:ff:ff:ff:ff:ff for broadcast/default keys
key_idx key index (0..3), usually 0 for unicast keys
set_tx Configure this key as the default Tx key (only used when driver does not support separate unicast/individual key
seq Sequence number/packet number, seq_len octets, the next packet number to be used for in replay protection; configured for Rx keys (in most cases, this is only used with broadcast keys and set to zero for unicast keys)
seq_len Length of the seq, depends on the algorithm: TKIP: 6 octets, CCMP: 6 octets

Returns:
0 on success, -1 on failure
This function uses SIOCSIWENCODEEXT by default, but tries to use SIOCSIWENCODE if the extended ioctl fails when configuring a WEP key.
