046c7b8994 eap-wsc: clear out intermediate key data 2016-08-30 14:41:58 -05:00
Denis Kenzior
39d6acb07d eap-wsc: Don't store AuthKey | KeyWrapKey | EMSK 
AuthKey is already uploaded into auth_key_hmac.  KeyWrapKey is now
uploaded into the AES-CBC(128) cipher.  We currently have no use for
EMSK.

So we no longer need to keep the wsc_session_key structure around.

757e4dbb90 wscutil: Prepare for parsing of Encrypted Settings 
Encrypted Settings TLVs are structured similarly to the various WSC
messages.  However, they lack a version2 extension field and use a Key
Wrap Authenticator element instead of Authenticator.

2cbbcb7434 eap-wsc: Load settings related to DevicePassword 
DevicePassword is the PIN, either static, dynamically generated or
entered by the user.  For PushButton mode, DevicePassword is set to
'00000000'.  It can also be provided via external means, such as NFC.

This patch allows DevicePassword to be externally configured into the
EAP-WSC layer.  Optionally, the secret nonce values can also be
provided for testing purposes.  If omitted, they will be generated using
l_getrandom.

ce596058cd eap-wsc: Implement load_settings method 
We use the load_settings method to bootstrap the internal state of the
EAP WSC state machine.  We require certain information to be provided by
the higher layers, namely:

Global Device parameters
 - Manufacturer
 - Model Name
 - Model Number
 - Serial Number
 - Device Name
 - Primary Device Type
 - OS Version

Session specific parameters
 - MAC Address
 - Configuration Methods
 - RF Bands

The following parameters are auto-generated for each new session, but
can be over-ridden if desired
 - Private Key
 - Enrollee Nonce

0a314004ce eap: expanded methods start packets at opcode 
Expanded EAP methods should get their packets for handling starting at
the op-code field.  They're not really interested in
type/vendor-id/vendor-type fields.
