[PATCH v2 1/3] Bluetooth: Fix sending incorrect LE CoC PDU in BT_CONNECT2 state

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Johan Hedberg <johan.hedberg@xxxxxxxxx>

For LE CoC L2CAP servers we don't do security level elevation during the
BT_CONNECT2 state (instead LE CoC simply sends an immediate error
response if the security level isn't high enough). Therefore if we get a
security level change while an LE CoC channel is in the BT_CONNECT2
state we should simply do nothing.
