WLAN SME

This library implements IEEE 802.11 SME functionality for both FullMAC and SoftMAC devices.

SME instances are created and hosted by a parent ‘wlanstack’ instance when WLAN interfaces start.

AP Implementation

Support for Access Points is currently fairly limited.

Client Implementation

Our client can connect to Open/WEP/WPA1/2/3 APs.

‘Top-level client’

• Responds to SME.fidl messages and initiates scans/connects/etc. as a result.
• Dispatches incoming MLME messages to the scan scheduler or state machine as appropriate.
• Initiates connections in response to completed join scans.

‘Client state machine’

• Manages all steps of a connection from authentication through completed association.
• Uses SME and EAPOL libraries to handle various authentication exchanges.
• Manages EAPOL/RSNA in the underlying ‘link state machine’
