Rather easy conflict resolution, the 'net' tree had bug fixes to make
sure we checked if a socket is a time-wait one or not and elide the
logging code if so.
Whereas on the 'net-next' side we are calculating the UID and GID from
the creds using different interfaces due to the user namespace changes
from Eric Biederman.

To make it clear that it may be called from contexts that may not have
any knowledge of L2CAP, we change the connection parameter, to receive
a hci_conn.
This also makes it clear that it is checking the security of the link.

To achive Man-In-The-Middle (MITM) level security with Low Energy,
we have to enable User Passkey Comparison. This commit modifies the
hard-coded JUST-WORKS pairing mechanism to support query via the MGMT
interface of Passkey comparison and User Confirmation.

The function crypto_blkcipher_setkey() called by smp_e()
can sleep, so all the crypto work has to be moved to
hci_dev workqueue.

The objective is to make the core to have as little as possible
information about SMP procedures and logic. Now, all the SMP
specific information is hidden from the core.

This adds support for generating and distributing all the keys
specified in the third phase of SMP.
This will make possible to re-establish secure connections, resolve
private addresses and sign commands.
For now, the values generated are random.

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.

This implementation only exchanges SMP messages between the Host and the
Remote. No keys are being generated. TK and STK generation will be
provided in further patches.

These simple commands will allow the SMP procedure to be started
and terminated with a not supported error. This is the first step
toward something useful.
