    Bluetooth: let the crypto subsystem generate the ecc privkey · c0153b0b
    Tudor Ambarus authored
    That Bluetooth SMP knows about the private key is pointless, since the
    detection of debug key usage is actually via the public key portion.
    With this patch, the Bluetooth SMP will stop keeping a copy of the
    ecdh private key and will let the crypto subsystem to generate and
    handle the ecdh private key, potentially benefiting of hardware
    ecc private key generation and retention.
    
    The loop that tries to generate a correct private key is now removed and
    we trust the crypto subsystem to generate a correct private key. This
    backup logic should be done in crypto, if really needed.
