330605423c Bluetooth: Fix L2CAP connection establishment
In hci_conn_security ( which is used during L2CAP connection
establishment ) test for HCI_CONN_ENCRYPT_PEND state also
sets this state, which is bogus and leads to connection time-out
on L2CAP sockets in certain situations (especially when
using non-ssp devices )

3158c50c33 Bluetooth: Add key size checks for SMP
This patch implements a check in smp cmd pairing request and pairing
response to verify if encryption key maximum size is compatible in both
slave and master when SMP Pairing is requested. Keys are also masked to
the correct negotiated size.

5d3de7df18 Bluetooth: Add support for SMP timeout
This patch adds support for disconnecting the link when SMP procedure
takes more than 30 seconds.

SMP begins when either the Pairing Request command is sent or the
Pairing Response is received, and it ends when the link is encrypted
(or terminated). Vol 3, Part H Section 3.4.

df3c3931ec Bluetooth: Fix accepting connect requests for defer_setup
When authentication completes we shouldn't blindly accept any pending
L2CAP connect requests. If the socket has the defer_setup feature
enabled it should still wait for user space acceptance of the connect
request. The issue only happens for non-SSP connections since with SSP
the L2CAP Connect request may not be sent for non-SDP PSMs before
authentication has completed successfully.
