STRUCT IEEE80211_KEY(9) Advanced driver interface STRUCT IEEE80211_KEY(9)

NAME

struct_ieee80211_key_conf - key information

SYNOPSIS

struct ieee80211_key_conf {


  void * drv_priv;


  atomic64_t tx_pn;


  u32 cipher;


  u8 icv_len;


  u8 iv_len;


  u8 hw_key_idx;


  u8 flags;


  s8 keyidx;


  u8 keylen;


  u8 key[0];
};

MEMBERS

drv_priv

pointer for driver use

tx_pn

PN used for TX on non-TKIP keys, may be used by the driver as well if it needs to do software PN assignment by itself (e.g. due to TSO)

cipher

The key´s cipher suite selector.

icv_len

The ICV length for this key type

iv_len

The IV length for this key type

hw_key_idx

To be set by the driver, this is the key index the driver wants to be given when a frame is transmitted and needs to be encrypted in hardware.

flags

key flags, see enum ieee80211_key_flags.

keyidx

the key index (0-3)

keylen

key material length

key[0]

key material. For ALG_TKIP the key is encoded as a 256-bit (32 byte)

DESCRIPTION

This key information is given by mac80211 to the driver by the set_key callback in struct ieee80211_ops.

DATA BLOCK

- Temporal Encryption Key (128 bits) - Temporal Authenticator Tx MIC Key (64 bits) - Temporal Authenticator Rx MIC Key (64 bits)
