Read the current IAC LAP values when initializing the controller. The
values are not used, but it is good to have them in the trace files
for debugging purposes.

When initializing a controller make sure to read out the number of
supported IAC and store its result. This value is needed to determine
if limited discoverable for BR/EDR can be configured or not.

The scan window parameter for connection establishment and passive
scanning needs to be smaller or equal than the scan interval.
Instead of waiting for a controller to reject these values later on,
just reject them right away.

If a socket was bound to an address type other than BR/EDR (such as LE)
we should reject trying to connect it to a BR/EDR address. The same
applies for binding to BR/EDR and trying to connect to non-BR/EDR.

This patch converts Set Discoverable to use an asynchronous request
along with its own completion callback. This is necessary for splitting
raw HCI socket use cases from mgmt, as well as for enabling the hooking
up of Advertising parameters together with the HCI_DISCOVERABLE flag
(coming in later patches).

Now that the connectable setting is also applicable for the LE side it's
possible that the HCI_CONNECTABLE flag is already set when changing the
BR/EDR setting from false to true while the controller is powered. In
this situation we need to update the BR/EDR scan mode to reflect the
setting. Additionally, since HCI_CONNECTABLE also applies to LE we must
not clear the HCI_CONNECTABLE flag when disabling bredr.

This patch updates the Set Connectable Management command to also update
the LE advertising type to either connectable or non-connectable
advertising. An extra helper function is needed for getting the right
advertising type since we can not only rely on the HCI_CONNECTABLE flag
but must also check for a pending Set Connectable command (in which case
the flag does not yet have its final value).

We need to ensure that the advertising data is up-to-date whenever
advertising is enabled, but when disabling advertising we do not need to
worry about it (since it will eventually get fixed as soon as
advertising is enabled again). This patch fixes this in the command
complete callback for set_adv_enable.

This patch moves all the decisions of which HCI commands to send (or not
to send) to the code between hci_req_init() and hci_req_run() this
allows us to further extend the request with further commands but still
keep the same logic of handling whether to return a direct mgmt response
in the case that no HCI commands were sent.

The L2CAP core should not look into the socket flags to figure out the
setting of defer setup. So introduce a L2CAP channel flag that mirrors
the socket flag.
Since the defer setup option is only set in one place this becomes a

The L2CAP connectionless channels use SOCK_DGRAM and recvmsg() and need
to receive the remote BD_ADDR and PSM information via msg_name from
the recvmsg() system call.
So in case the L2CAP socket is for connectionless channels, provide
a msg_name callback that can update the data. Also store the remote
BD_ADDR and PSM in the skb so it can be extracted later on.

The L2CAP sockets can use BR/EDR public, LE public and LE random
addresses for various combinations of source and destination
devices. So make sure that getsockname(), getpeername() and
accept() return the correct address type.
For this the address type of the source and destination is stored
with the L2CAP channel information. The stored address type is
not the one specific for the HCI protocol. It is the address
type used for the L2CAP sockets and the management interface.
The underlying HCI connections store the HCI address type. If
needed, it gets converted to the socket address type.

With the effort of abstracting the L2CAP socket from the underlying
L2CAP channel it is important to store the source and destination
address information directly in the L2CAP channel structure.
Direct access to the HCI connection address information is not
possible since they might not be avaiable at L2CAP channel
creation time. The address information will be updated when
the underlying BR/EDR or LE connection status changes.

The source addressed was based on the public address of the HCI device,
but with LE connections this not always the case. For example single
mode LE-only controllers would use a static random address. And this
address is configured by userspace.

the correct source address for each HCI connection.

The bdaddr_to_le() function tries to convert the internal address
type to one that matches the HCI address type for LE. It does not
handle any address types not used by LE and in the end just make
the code a lot harder to read.
So instead of just hiding behind a magic function, just convert
the internal address type where it needs to be converted. And it
turns out that these are only two cases anyway. One when creating
new LE connections and the other when loading the long term keys.
In both cases this makes it more clear on what it going on.
