wpa_eapol_key_send - Send WPA/RSN EAPOL-Key message @sm: Pointer to WPA state machine data from wpa_sm_init() @kck: Key Confirmation Key (KCK, part of PTK) @kck_len: KCK length in octets @ver: Version field from Key Info @dest: Destination address for the frame @proto: Ethertype (usually ETH_P_EAPOL) @msg: EAPOL-Key message @msg_len: Length of message @key_mic: Pointer to the buffer to which the EAPOL-Key MIC is written

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.

mlme_setprotection - MLME-SETPROTECTION.request primitive @priv: Private driver interface data @addr: Address of the station for which to set protection (may be %NULL for group keys) @protect_type: MLME_SETPROTECTION_PROTECT_TYPE_* @key_type: MLME_SETPROTECTION_KEY_TYPE_* Returns: 0 on success, -1 on failure This is an optional function that can be used to set the driver to require protection for Tx and/or Rx frames. This uses the layer interface defined in IEEE 802.11i-2004 clause 10.3.22.1 (MLME-SETPROTECTION.request). Many drivers do not use explicit set protection operation; instead, they set protection implicitly based on configured keys.

pmksa_cache_get_current - Get the current used PMKSA entry @sm: Pointer to WPA state machine data from wpa_sm_init() Returns: Pointer to the current PMKSA cache entry or %NULL if not available
