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

NAME

struct_ieee80211_key_conf - key information

SYNOPSIS

struct ieee80211_key_conf {
  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

tx_pn
PN used for TX 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) data block: - Temporal Encryption Key (128 bits) - Temporal Authenticator Tx MIC Key (64 bits) - Temporal Authenticator Rx MIC Key (64 bits)

DESCRIPTION

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