Currently, we accept per-STA GTK for any interface type if the IBSS_RSN flag is set, which doesn't make sense, and also accept various key indices that aren't really (meant to be) supported, such as IGTK/BIGTK on IBSS or AP_VLAN etc. For MESH and NAN_DATA interface types, per-STA GTKs are required, so their support shouldn't depend on IBSS_RSN. Conversely a driver setting IBSS_RSN doesn't really say it also accepts per-STA GTK for other interface types. Move more checks into cfg80211_valid_key_idx() and make them more precise: - allow IGTK and, if supported, BIGTK for NAN - allow per-STA (RX) GTK only for - NAN_DATA - IBSS if IBSS_RSN is supported - MESH - allow B/I/GTK for station/P2P-client without mac_addr for RX with the current AP (historic API quirk), subject to support - allow TX GTK for AP/P2P-GO/AP_VLAN - allow TX IGTK/BIGTK for AP/P2P-GO subject to support Other settings are rejected, clearing up corner cases and disallowing unexpected settings.
