    cfg80211/nl80211: Offload OWE processing to user space in AP mode · cb74e977
    Sunil Dutt authored
    This interface allows the host driver to offload OWE processing
    to user space. This intends to support OWE (Opportunistic Wireless
    Encryption) AKM by the drivers that implement SME but rely on the
    user space for the cryptographic/OWE processing in AP mode. Such
    drivers are not capable of processing/deriving the DH IE.
    
    A new NL80211 command - NL80211_CMD_UPDATE_OWE_INFO is introduced
    to send the request/event between the host driver and user space.
    
    Driver shall provide the OWE info (MAC address and DH IE) of
    the peer to user space for cryptographic processing of the DH IE
    through the event. Accordingly, the user space shall update the
    OWE info/DH IE to the driver.
    
    Following is the sequence in AP mode for OWE authentication.
    
    Driver passes the OWE info obtained from the peer in the
    Association Request to the user space through the event
    cfg80211_update_owe_info_event. User space shall process the
    OWE info received and generate new OWE info. This OWE info is
    passed to the driver through NL80211_CMD_UPDATE_OWE_INFO
    request. Driver eventually uses this OWE info to send the
    Association Response to the peer.
    
    This OWE info in the command interface carries the IEs that include
    PMKID of the peer if the PMKSA is still valid or an updated DH IE
    for generating a new PMKSA with the peer.
