Hi,
Disclaimer: these patches are implememented on top of the previous
SM work, so they are subject to change.
These patches start support for generating and storing the keys
produced during SM Phase 3. These patches will open the way for
having proper pairing over Low Energy connections.
As standard HCI commands don't provide any way for being notified
of new Low Energy keys, these patches extend some commands and
events from the Management Interface.
I still don't like the way that the STK is stored:
"Bluetooth: Use the link key list to temporarily store the STK"
I would like very much to hear some alternative ideas.
Another thing that I would like your opinion on is that some LE
profiles have some restrictions on the size of the key that was
used for encryption. I added a new field to struct bt_security
for this purpose:
"Bluetooth: Add support for returning the encryption key size"
The associated userspace patches can be found here[1].
