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.
