When starting up a controller make sure that all LE white list entries
are cleared. Normally the HCI Reset takes care of this. This is just
in case no HCI Reset has been executed.

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.

This patch adds to debugfs the le_auto_conn file. This file will be
used to test LE auto connection infrastructure.
This file accept writes in the following format:
"add <address> <address_type> [auto_connect]"
"del <address> <address_type>"
"clr"
The <address type> values are:
* 0 for public address
* 1 for random address
The [auto_connect] values are (for more details see struct hci_
conn_params):
* 0 for disabled (default)
* 1 for always
* 2 for link loss
So for instance, if you want the kernel autonomously establishes
connections with device AA:BB:CC:DD:EE:FF (public address) every
time the device enters in connectable mode (starts advertising),
you should run the command:
$ echo "add AA:BB:CC:DD:EE:FF 0 1" > /sys/kernel/debug/bluetooth/hci0/le_auto_conn
To delete the connection parameters for that device, run the command:
$ echo "del AA:BB:CC:DD:EE:FF 0" > /sys/kernel/debug/bluetooth/hci0/le_auto_conn
To clear the connection parameters list, run the command:
$ echo "clr" > /sys/kernel/debug/bluetooth/hci0/le_auto_conn
Finally. to get the list of connection parameters configured in kernel,
read the le_auto_conn file:
$ cat /sys/kernel/debug/bluetooth/hci0/le_auto_conn
This file is created only if LE is enabled.

Only identity addresses are inserted into hdev->pend_le_conns. So,
in order to support resolvable private addresses in auto connection
mechanism, we should resolve the address before checking for pending
connections.
Thus, this patch adds an extra check in check_pending_le_conn() and
updates 'addr' and 'addr_type' variables before hci_pend_le_conn_
lookup().

We should only accept connection parameters from identity addresses
(public or random static). Thus, we should check the address type
in hci_conn_params_add().
Additionally, since the IRK is removed during unpair, we should also
remove the connection parameters from that device.

When hdev is closed (e.g. Mgmt power off command, RFKILL or controller
is reset), the ongoing active connections are silently dropped by the
controller (no Disconnection Complete Event is sent to host). For that
reason, the devices that require HCI_AUTO_CONN_ALWAYS are not added to
hdev->pend_le_conns list and they won't auto connect.
So to fix this issue, during hdev closing, we remove all pending LE
connections. After adapter is powered on, we add a pending LE connection
for each HCI_AUTO_CONN_ALWAYS address.
This way, the auto connection mechanism works propely after a power
off and power on sequence as well as RFKILL block/unblock.

This patch modifies hci_conn_params_add() and hci_conn_params_del() so
they also add/delete pending LE connections according to the auto_
connect option. This way, background scan is automatically triggered/
untriggered when connection parameters are added/removed.
For instance, when a new connection parameters with HCI_AUTO_CONN_ALWAYS
option is added and we are not connected to the device, we add a pending
LE connection for that device.
Likewise, when the connection parameters are updated we add or delete
a pending LE connection according to its new auto_connect option.
Finally, when the connection parameter is deleted we also delete the
pending LE connection (if any).

This patch introduces the LE auto connection options: HCI_AUTO_CONN_
ALWAYS and HCI_AUTO_CONN_LINK_LOSS. Their working mechanism are
described as follows:
The HCI_AUTO_CONN_ALWAYS option configures the kernel to always re-
establish the connection, no matter the reason the connection was
terminated. This feature is required by some LE profiles such as
HID over GATT, Health Thermometer and Blood Pressure. These profiles
require the host autonomously connect to the device as soon as it
enters in connectable mode (start advertising) so the device is able
to delivery notifications or indications.
The BT_AUTO_CONN_LINK_LOSS option configures the kernel to re-
establish the connection in case the connection was terminated due
to a link loss. This feature is required by the majority of LE
profiles such as Proximity, Find Me, Cycling Speed and Cadence and
Time.

This patch introduces the LE auto connection infrastructure which
will be used to implement the LE auto connection options.
In summary, the auto connection mechanism works as follows: Once the
first pending LE connection is created, the background scanning is
started. When the target device is found in range, the kernel
autonomously starts the connection attempt. If connection is
established successfully, that pending LE connection is deleted and
the background is stopped.
To achieve that, this patch introduces the hci_update_background_scan()
which controls the background scanning state. This function starts or
stops the background scanning based on the hdev->pend_le_conns list. If
there is no pending LE connection, the background scanning is stopped.
Otherwise, we start the background scanning.
Then, every time a pending LE connection is added we call hci_update_
background_scan() so the background scanning is started (in case it is
not already running). Likewise, every time a pending LE connection is
deleted we call hci_update_background_scan() so the background scanning
is stopped (in case this was the last pending LE connection) or it is
started again (in case we have more pending LE connections). Finally,
we also call hci_update_background_scan() in hci_le_conn_failed() so
the background scan is restarted in case the connection establishment
fails. This way the background scanning keeps running until all pending
LE connection are established.
At this point, resolvable addresses are not support by this
infrastructure. The proper support is added in upcoming patches.

hci_connect() is a very simple and useless wrapper of hci_connect_acl
and hci_connect_le functions. Addtionally, all places where hci_connect
is called the link type value is passed explicitly. This way, we can

Some LE controllers don't support scanning and creating a connection
at the same time. So we should always stop scanning in order to
establish the connection.
Since we may prematurely stop the discovery procedure in favor of
the connection establishment, we should also cancel hdev->le_scan_
disable delayed work and set the discovery state to DISCOVERY_STOPPED.
This change does a small improvement since it is not mandatory the
user stops scanning before connecting anymore. Moreover, this change
is required by upcoming LE auto connection mechanism in order to work
properly with controllers that don't support background scanning and
connection establishment at the same time.
In future, we might want to do a small optimization by checking if
controller is able to scan and connect at the same time. For now,
we want the simplest approach so we always stop scanning (even if
the controller is able to carry out both operations).

The Core Specification (4.1) leaves room for sending an SMP Identity
Address Information PDU with an all-zeros BD_ADDR value. This
essentially means that we would not have an Identity Address for the
device and the only means of identifying it would be the IRK value
itself.
Due to lack of any known implementations behaving like this it's best to
keep our implementation as simple as possible as far as handling such
situations is concerned. This patch updates the Identity Address
Information handler function to simply ignore the IRK received from such
a device.

When the connectable setting is toggled using mgmt_set_connectable the
HCI_CONNECTABLE flag will only be set once the related HCI commands
succeed. When determining what kind of advertising to do we need to
therefore also check whether there is a pending Set Connectable command
in addition to the current flag value.
The enable_advertising function was already taking care of this for the
advertising type with the help of the get_adv_type function, but was
failing to do the same for the address type selection. This patch
converts the get_adv_type function to be more generic in that it returns
the expected connectable state and updates the enable_advertising
function to use the return value both for the advertising type as well
as the advertising address type.

When trying to allocate skb for new PDU, l2cap_chan is unlocked so we
can sleep waiting for memory as otherwise there's possible deadlock as
fixed in e454c84464. However, in a6a5568c03 lock was moved from socket
to channel level and it's no longer safe to just unlock and lock again
without checking l2cap_chan state since channel can be disconnected
when lock is not held.
This patch adds missing checks for l2cap_chan state when returning from
call which allocates skb.
Scenario is easily reproducible by running rfcomm-tester in a loop.

To be friendly to user space and to behave well with controllers that
lack a proper internal power off procedure we should try to clean up as
much state as possible before requesting the HCI driver to power off.
This patch updates the power off procedure that's triggered by
mgmt_set_powered to clean any scan modes, stop LE scanning and
advertising and to disconnect any open connections.
The asynchronous cleanup procedure uses the HCI request framework,
however since HCI_Disconnect is only covered until its Command Status
event we need some extra tracking/waiting of disconnections. This is
done by monitoring when hci_conn_count() indicates that there are no
more connections.

When we initiate LE connections we need to update the local random
address if necessary. This patch updates the LE connection creation
mechanism to use the new hci_update_random_address() function to set the
own_address_type parameter and to update the local random address if
necessary.

This patch adds a convenience function for updating the local random
address which is needed before advertising, scanning and initiating LE
connections.
