The commands are structured to allow separate authentication and association steps, i.e., the interface between kernel and user space is similar to the MLME SAP interface in IEEE 802.11 standard and an user space application takes the role of the SME. The patch introduces MLME-AUTHENTICATE.request, MLME-{,RE}ASSOCIATE.request, MLME-DEAUTHENTICATE.request, and MLME-DISASSOCIATE.request primitives. The authentication and association commands request the actual operations in two steps (assuming the driver supports this; if not, separate authentication step is skipped; this could end up being a separate "connect" command). The initial implementation for mac80211 uses the current net/mac80211/mlme.c for actual sending and processing of management frames and the new nl80211 commands will just stop the current state machine from moving automatically from authentication to association. Future cleanup may move more of the MLME operations into cfg80211. The goal of this design is to provide more control of authentication and association process to user space without having to move the full MLME implementation. This should be enough to allow IEEE 802.11r FT protocol and 802.11s SAE authentication to be implemented. Obviously, this will also bring the extra benefit of not having to use WEXT for association requests with mac80211. An example implementation of a user space SME using the new nl80211 commands is available for wpa_supplicant. This patch is enough to get IEEE 802.11r FT protocol working with over-the-air mechanism (over-the-DS will need additional MLME primitives for handling the FT Action frames).
