      Bluetooth: Update class of device on discoverable timeout · d1967ff8
      由 Marcel Holtmann 提交于 
      When the discoverable timeout triggers and limited discoverable mode
was used, then the class of device needs to be updated to remove
the limited discoverable bit.

To keep the class of device logic in a central place, expose a new
function mgmt_discoverable_timeout that can be called from the
timeout callback. In case the class of device value needs updating,
it will add the HCI command to the transaction.

      Bluetooth: Add support for entering limited discoverable mode · 310a3d48
      由 Marcel Holtmann 提交于 
      The limited discoverable mode should be used when a device is only
discoverable for a certain amount of time and after that it returns
back into being non-discoverable.

This adds another option to the set discoverable management command
to clearly distinguish limited discoverable from general discoverable
mode.

While the general discoverable mode can be set with a specific
timeout or as permanent setting, the limited discoverable mode
requires a timeout. The timeout is flexible and the kernel will
not enforce any specific limitations. That GAP part of this is
required by userspace to enforce according to the Bluetooth core
specification.

Devices in limited discoverable mode can still be found by the
general discovery procedure. It is mandatory that a device sets
both GIAC and LIAC when entering limited discoverable mode.

      Bluetooth: Remove pointless bdaddr_to_le() helper function · 79d95a19
      由 Marcel Holtmann 提交于 
      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.

      Bluetooth: Fix HCI init for 1st generation BlueFRITZ! devices · 4ca048e3
      由 Marcel Holtmann 提交于 
      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.

      Bluetooth: Fix endless loop with HCI_QUIRK_RESET_ON_CLOSE · 3a6afbd2
      由 Marcel Holtmann 提交于 
      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.

      Bluetooth: Make LE scan interval and window a controller option · bef64738
      由 Marcel Holtmann 提交于 
      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.
