Marcel Holtmann 98e0f7ea4a Bluetooth: Remove l2cap_conn->src and l2cap_conn->dst usage from L2CAP
The l2cap_conn->src and l2cap_conn->dst addresses are just a pointers
to hci_conn structure. Use hci_conn->hdev->bdaddr and hci_conn->dst
directly instead.

Marcel Holtmann ce39fb4e45 Bluetooth: Remove l2cap_conn->src and l2cap_conn->dst usage from SMP
The l2cap_conn->src and l2cap_conn->dst addresses are just a pointer
to hci_conn->hdev->bdaddr and hci_conn->dst structures. Use the data
provided by hci_conn directly. This is done for hci_conn->dst_type
already anyway and with this change it makes it a lot clearer were
the address information comes from.

Marcel Holtmann 3124b84309 Bluetooth: Allow 3D profile to use security mode 4 level 0
The PSM 0x0021 is dedicated to the 3D profile and has permission to
use security mode 4 level 0 for L2CAP connectionless unicast data
transfers.

When establishing a L2CAP connectionless channel on PSM 0x0021, it
will no longer force Secure Simple Pairing.

Marcel Holtmann 43b1b8dfb4 Bluetooth: Fix PSM value for L2CAP connectionless data packets
The put_unaligned() for setting the PSM is missing the (__le16 *)
cast. Without this, the PSM information transmitted over the air
are bogus.

In addition, print the used PSM value in the debug message so this
becomes easier to debug in the future.

Marcel Holtmann 4ca048e3a3 Bluetooth: Fix HCI init for 1st generation BlueFRITZ! devices
The 1st generation of BlueFRITZ! devices from AVM Berlin pretend
to be HCI version 1.2 controllers, but they are not. They are simple
Bluetooth 1.1 devices.

Since this company never created any newer controllers, it is safe
to use the manufacturer ID instead of an USB quirk.

Marcel Holtmann a82974c9f4 Bluetooth: Don't advertise high speed support without SSP
It is not allowed to enable high speed support when Secure Simple
Pairing is not available or disabled.

However the support for high speed gets advertised on a controller
that does not even support Secure Simple Pairing. Since there is
no way to enable high speed support on such a controller, do not
even advertise its support.

Marcel Holtmann 3a6afbd217 Bluetooth: Fix endless loop with HCI_QUIRK_RESET_ON_CLOSE
Really early versions of the Bluetooth specification were unclear
with the behavior of HCI Reset for USB devices. They assumed that
also an USB reset needs to be issued. Later Bluetooth specifications
cleared this out and it is safe to call HCI Reset without affecting
the transport.

For old devices that misbehave, the HCI_QUIRK_RESET_ON_CLOSE quirk
was introduced to postpone the HCI Reset until the device was no
longer in use.

One of these devices is the Digianswer BPA-105 Bluetooth Protocol
Analyzer. The only problem now is that with the quirk set, the
HCI Reset is also executed at the end of the setup phase. So the
controller gets configured and then it disconnects from the USB
bus, connects again, gets configured and of course disconnects
again. This game goes on forever.

For devices that need HCI_QUIRK_RESET_ON_CLOSE it is important
that the HCI Reset is not executed after the setup phase. In
specific when HCI_AUTO_OFF is set, do not call HCI Reset when
closing the device.

Marcel Holtmann 14b49b9a49 Bluetooth: Add management command for setting LE scan parameters
The scan interval and window parameters are used for LE passive
background scanning and connection establishment. This allows
userspace to change the values.

These two values should be kept in sync with whatever is used for
the scan parameters service on remote devices. And it puts the
controlling daemon (for example bluetoothd) in charge of setting
the values.

Main use case would be to switch between two sets of values. One
for foreground applications and one for background applications.

At this moment, the values are only used for manual connection
establishment, but soon that should be extended to background
scanning and automatic connection establishment.

Marcel Holtmann bef64738e3 Bluetooth: Make LE scan interval and window a controller option
The scan interval and window for LE passive scanning and connection
establishment should be configurable on a per controller basis. So
introduce a setting that later on will allow modifying it.

This setting does not affect LE active scanning during device
discovery phase. As long as that phase uses interleaved discovery,
it will continuously scan.
