# enum\_ieee80211\_key\_flags(9)

key flags

## NAME

enum\_ieee80211\_key\_flags - key flags

## SYNOPSIS

```
enum ieee80211_key_flags {
  IEEE80211_KEY_FLAG_GENERATE_IV_MGMT,
  IEEE80211_KEY_FLAG_GENERATE_IV,
  IEEE80211_KEY_FLAG_GENERATE_MMIC,
  IEEE80211_KEY_FLAG_PAIRWISE,
  IEEE80211_KEY_FLAG_SW_MGMT_TX,
  IEEE80211_KEY_FLAG_PUT_IV_SPACE,
  IEEE80211_KEY_FLAG_RX_MGMT
};
```

## CONSTANTS

IEEE80211\_KEY\_FLAG\_GENERATE\_IV\_MGMT

This flag should be set by the driver for a CCMP key to indicate that is requires IV generation only for managment frames (MFP).

IEEE80211\_KEY\_FLAG\_GENERATE\_IV

This flag should be set by the driver to indicate that it requires IV generation for this particular key.

IEEE80211\_KEY\_FLAG\_GENERATE\_MMIC

This flag should be set by the driver for a TKIP key if it requires Michael MIC generation in software.

IEEE80211\_KEY\_FLAG\_PAIRWISE

Set by mac80211, this flag indicates that the key is pairwise rather then a shared key.

IEEE80211\_KEY\_FLAG\_SW\_MGMT\_TX

This flag should be set by the driver for a CCMP key if it requires CCMP encryption of management frames (MFP) to be done in software.

IEEE80211\_KEY\_FLAG\_PUT\_IV\_SPACE

This flag should be set by the driver if space should be prepared for the IV, but the IV itself should not be generated. Do not set together with *IEEE80211\_KEY\_FLAG\_GENERATE\_IV* on the same key.

IEEE80211\_KEY\_FLAG\_RX\_MGMT

This key will be used to decrypt received management frames. The flag can help drivers that have a hardware crypto implementation that doesn't deal with management frames properly by allowing them to not upload the keys to hardware and fall back to software crypto. Note that this flag deals only with RX, if your crypto engine can't deal with TX you can also set the **IEEE80211\_KEY\_FLAG\_SW\_MGMT\_TX** flag to encrypt such frames in SW.

## DESCRIPTION

These flags are used for communication about keys between the driver and mac80211, with the *flags* parameter of struct ieee80211\_key\_conf.
