| 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;
s8 keyidx;
u16 flags;
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.
keyidx
the key index (0-3)
flags
key flags, see enum ieee80211_key_flags.
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)
