    cfg80211/nl80211: Optional authentication offload to userspace · 40cbfa90
    Srinivas Dasari authored
    This interface allows the host driver to offload the authentication to
    user space. This is exclusively defined for host drivers that do not
    define separate commands for authentication and association, but rely on
    userspace SME (e.g., in wpa_supplicant for the ~WPA_DRIVER_FLAGS_SME
    case) for the authentication to happen. This can be used to implement
    SAE without full implementation in the kernel/firmware while still being
    able to use NL80211_CMD_CONNECT with driver-based BSS selection.
    
    Host driver sends NL80211_CMD_EXTERNAL_AUTH event to start/abort
    authentication to the port on which connect is triggered and status
    of authentication is further indicated by user space to host
    driver through the same command response interface.
    
    User space entities advertise this capability through the
    NL80211_ATTR_EXTERNAL_AUTH_SUPP flag in the NL80211_CMD_CONNECT request.
    Host drivers shall look at this capability to offload the authentication.
