We need to ensure that we do not send events to user space with the
identity address if we have not yet notified user space of the IRK. The
code was previously trying to handle this for the mgmt_pair_device
response (which worked well enough) but this is not the only connection
related event that might be sent to user space before pairing is
successful: another important event is Device Disconnected.
The issue can actually be solved more simply than the solution
previously used for mgmt_pair_device. Since we do have the identity
address tracked as part of the remote IRK struct we can just copy it
over from there to the hci_conn struct once we've for real sent the mgmt
event for the new IRK.

The passkey_notify and user_confirm functions in mgmt.c were expecting
different endianess for the passkey, leading to a big endian bug and
sparse warning in recently added SMP code. This patch converts both
functions to expect host endianess and do the conversion to little
endian only when assigning to the mgmt event struct.

In Secure Connections Only mode, it is required that Secure Connections

It is possible that pairing fails after we've already received remote
identity information. One example of such a situation is when
re-encryption using the LTK fails. In this case the hci_conn object has
already been updated with the identity address but user space does not
yet know about it (since we didn't notify it of the new IRK yet).
To ensure user space doesn't get a Pair Device command response with an
unknown address always use the same address in the response as was used
for the original command.

When performing SMP pairing with MITM protection one side needs to
enter the passkey while the other side displays to the user what needs
to be entered. Nowhere in the SMP specification does it say that the
displaying side needs to any kind of confirmation of the passkey, even
though a code comment in smp.c implies this.
This patch removes the misleading comment and converts the code to use
the passkey notification mgmt event instead of the passkey confirmation
mgmt event.

In some cases the current 250ms delay is not enough for the remote to

The SMP specification is written with the assumption that both key
information, plaintextData and encryptedData follow the same little
endian byte ordering as the rest of SMP.
Since the kernel crypto routines expect big endian data the code has had
to do various byte swapping tricks to make the behavior as expected,
however the swapping has been scattered all around the place.
This patch centralizes the byte order swapping into the smp_e function
by making its public interface match what the other SMP functions expect
as per specification. The benefit is vastly simplified calls to smp_e.

Commit 975508879 "Bluetooth: make bluetooth 6lowpan as an option"
ensures that 6LOWPAN_IPHC is turned on when we have BT_6LOWPAN
enabled in Kconfig, but it allows building the IPHC code as
a loadable module even if the entire Bluetooth stack is built-in,
and that causes a link error.
We can solve that by moving the 'select' statement into CONFIG_BT,
which is a "tristate" option to enforce that 6LOWPAN_IPHC can
only be a module if BT also is a module.

To avoid flooding the host with useless advertising reports during
background scan, we enable the duplicates filter from controller.
However, enabling duplicates filter requires a small change in
background scan routine in order to fix the following scenario:
1) Background scan is running.
2) A device disconnects and starts advertising.
3) Before host gets the disconnect event, the advertising is reported
to host. Since there is no pending LE connection at that time,
nothing happens.
4) Host gets the disconnection event and adds a pending connection.
5) No advertising is reported (since controller is filtering) and the
connection is never established.
So, to address this scenario, we should always restart background scan
to unsure we don't miss any advertising report (due to duplicates
filter).

In case the pairable option has been disabled, the pairing procedure
does not create keys for bonding. This means that these generated keys
should not be stored persistently.
For LTK and CSRK this is important to tell userspace to not store these
new keys. They will be available for the lifetime of the device, but
after the next power cycle they should not be used anymore.
Inform userspace to actually store the keys persistently only if both
sides request bonding.

This patch fixes authentication failure on LE link re-connection when
BlueZ acts as slave (peripheral). LTK is removed from the internal list
after its first use causing PIN or Key missing reply when re-connecting
the link. The LE Long Term Key Request event indicates that the master

Pre-condition: BlueZ host paired and running as slave.
How to reproduce(master):
1) Establish an ACL LE encrypted link
2) Disconnect the link
3) Try to re-establish the ACL LE encrypted link (fails)

The stop_scan_complete function was used as an intermediate step before
doing the actual connection creation. Since we're using hci_request
there's no reason to have this extra function around, i.e. we can simply
put both HCI commands into the same request.
The single task that the intermediate function had, i.e. indicating
discovery as stopped is now taken care of by a new
HCI_LE_SCAN_INTERRUPTED flag which allows us to do the discovery state
update when the stop scan command completes.

The discovery process has a timer for disabling scanning, however
scanning might be disabled through other means too like the auto-connect
process. We should therefore ensure that the timer is never active
after sending a HCI command to disable scanning.
There was some existing code in stop_scan_complete trying to avoid the
timer when a connect request interrupts a discovery procedure, but the
other way around was not covered. This patch covers both scenarios by
canceling the timer as soon as we get a successful command complete for
the disabling HCI command.

It's not strictly speaking required to re-encrypt a link once we receive

before notifying user space of the distributed keys.

LE connection attempts do not have a controller side timeout in the same
way as BR/EDR has (in form of the page timeout). Since we always do
scanning before initiating connections the attempts are always expected
to succeed in some reasonable time.
This patch adds a timer which forces a cancellation of the connection
attempt within 20 seconds if it has not been successful by then. This
way we e.g. ensure that mgmt_pair_device times out eventually and gives

were used to establish the connection. These may be different from the
Identity Addresses or even the current RPA. To guarantee that we have

separately from the very beginning of the connection.
For outgoing connections we set the values as soon as we get a

Different controllers behave differently when HCI_Set_Random_Address is
called while they are advertising or have a HCI_LE_Create_Connection in
progress. Some take the newly written address into use for the pending
operation while others use the random address that we had at the time
that the operation started.
Due to this undefined behavior and for the fact that we want to reliably
determine the initiator address of all connections for the sake of SMP
it's best to simply prevent the random address update if we have these
problematic operations in progress.
This patch adds a set_random_addr() helper function for the use of
hci_update_random_address which contains the necessary checks for
advertising and ongoing LE connections.
One extra thing we need to do is to clear the HCI_ADVERTISING flag in
the enable_advertising() function before sending any commands. Since
re-enabling advertising happens by calling first disable_advertising()
and then enable_advertising() all while having the HCI_ADVERTISING flag
set. Clearing the flag lets the set_random_addr() function know that
it's safe to write a new address at least as far as advertising is
concerned.

When powering off and disconnecting devices we should also consider
connections which have not yet reached the BT_CONNECTED state. They may
not have a valid handle yet and simply sending a HCI_Disconnect will not
work.
This patch updates the code to either disconnect, cancel connection
creation or reject incoming connection creation based on the current
conn->state value as well as the link type in question.
When the power off procedure results in canceling connection attempts
instead of disconnecting connections we get a connection failed event
instead of a disconnection event. Therefore, we also need to have extra
code in the mgmt_connect_failed function to check if we should proceed
with the power off or not.

To know the real source address for incoming connections (needed e.g.
for SMP) we should store the own_address_type parameter that was used
for the last HCI_LE_Write_Advertising_Parameters command. This patch
adds a proper command complete handler for the command and stores the
address type in a new adv_addr_type variable in the hci_dev struct.

According to mgmt-api.txt, in case of confirm name command,
cmd_complete should be always use as a response. Not command status
as it is now for failures.
Using command complete on failure is actually better as client might
be interested in device address for which confirm name failed.
