/**
|
||
|
|
* set_key - Configure encryption key
|
||
|
|
* @ifname: Interface name (for multi-SSID/VLAN support)
|
||
|
|
* @priv: private driver interface data
|
||
|
|
* @alg: encryption algorithm (%WPA_ALG_NONE, %WPA_ALG_WEP,
|
||
|
|
* %WPA_ALG_TKIP, %WPA_ALG_CCMP, %WPA_ALG_IGTK, %WPA_ALG_PMK);
|
||
|
|
* %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; 0..4095 for
|
||
|
|
* IGTK
|
||
|
|
* @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, IGTK: 6 octets
|
||
|
|
* @key: key buffer; TKIP: 16-byte temporal key, 8-byte Tx Mic key,
|
||
|
|
* 8-byte Rx Mic Key
|
||
|
|
* @key_len: length of the key buffer in octets (WEP: 5 or 13,
|
||
|
|
* TKIP: 32, CCMP: 16, IGTK: 16)
|
||
|
|
*
|
||
|
|
* Returns: 0 on success, -1 on failure
|
||
|
|
*
|
||
|
|
* Configure the given key for the kernel driver. If the driver
|
||
|
|
* supports separate individual keys (4 default keys + 1 individual),
|
||
|
|
* addr can be used to determine whether the key is default or
|
||
|
|
* individual. If only 4 keys are supported, the default key with key
|
||
|
|
* index 0 is used as the individual key. STA must be configured to use
|
||
|
|
* it as the default Tx key (set_tx is set) and accept Rx for all the
|
||
|
|
* key indexes. In most cases, WPA uses only key indexes 1 and 2 for
|
||
|
|
* broadcast keys, so key index 0 is available for this kind of
|
||
|
|
* configuration.
|
||
|
|
*
|
||
|
|
* Please note that TKIP keys include separate TX and RX MIC keys and
|
||
|
|
* some drivers may expect them in different order than wpa_supplicant
|
||
|
|
* is using. If the TX/RX keys are swapped, all TKIP encrypted packets
|
||
|
|
* will tricker Michael MIC errors. This can be fixed by changing the
|
||
|
|
* order of MIC keys by swapping te bytes 16..23 and 24..31 of the key
|
||
|
|
* in driver_*.c set_key() implementation, see driver_ndis.c for an
|
||
|
|
* example on how this can be done.
