9dc6ceb379 Bluetooth: Handle error command status for AUTH_REQUESTED command
When AUTH_REQUESTED command status is error status, do the bonding
cleanup, so that there will not be any problem for next time
pairing process and in user space.

On ACL connection complete with a remote device, the remote

current change is to read this information from controller to

e8b0b4033e Bluetooth: Fix HCI channel reference counting
When an incoming HCI logical link event came in at the same time
a socket structure was deleted, it was possible to end up with a stale
pointer to the socket.  The socket and associated HCI channel struct
need to be properly reference counted so they are not freed
prematurely.

The mgmt_ev_device_connected signal must be sent before any event

e.g. device authorization for the sockets will fail with ENOTCONN as
user space things that there is no baseband link.

This patch fixes the issue by ensuring that the device_connected event
if sent (if it hasn't been so already) as soon as the first ACL data
packet arrives from the remote device.

a7d7723ae7 Bluetooth: notify userspace of security level change
It fixes L2CAP socket based security level elevation during a
connection. The HID profile needs this (for keyboards) and it is the only
way to achieve the security level elevation when using the management
interface to talk to the kernel (hence the management enabling patch
being the one that exposes this issue).

It enables the userspace a security level change when the socket is
already connected and create a way to notify the socket the result of the
request. At the moment of the request the socket is made non writable, if
the request fails the connections closes, otherwise the socket is made
writable again, POLL_OUT is emmited.

07021e2708 Bluetooth: Allow SCO/eSCO packet type selection for outgoing SCO connections.
__u16 sco_pkt_type is introduced to struct sockaddr_sco. It allows bitwise
selection of SCO/eSCO packet types. Currently those bits are:

0x0001 HV1 may be used.
0x0002 HV2 may be used.
0x0004 HV3 may be used.
0x0008 EV3 may be used.
0x0010 EV4 may be used.
0x0020 EV5 may be used.
0x0040 2-EV3 may be used.
0x0080 3-EV3 may be used.
0x0100 2-EV5 may be used.
0x0200 3-EV5 may be used.

This is similar to the Packet Type parameter in the HCI Setup Synchronous
Connection Command, except that we are not reversing the logic on the EDR bits.
This makes the use of sco_pkt_tpye forward portable for the use case of
white-listing packet types, which we expect will be the primary use case.

If sco_pkt_type is zero, or userspace uses the old struct sockaddr_sco,
then the default behavior is to allow all packet types.

Packet type selection is just a request made to the Bluetooth chipset, and
it is up to the link manager on the chipset to negiotiate and decide on the
actual packet types used. Furthermore, when a SCO/eSCO connection is eventually
made there is no way for the host stack to determine which packet type was used
(however it is possible to get the link type of SCO or eSCO).

sco_pkt_type is ignored for incoming SCO connections. It is possible
to add this in the future as a parameter to the Accept Synchronous Connection
Command, however its a little trickier because the kernel does not
currently preserve sockaddr_sco data between userspace calls to accept().

The most common use for sco_pkt_type will be to white-list only SCO packets,
which can be done with the hci.h constant SCO_ESCO_MASK.

This patch is motivated by broken Bluetooth carkits such as the Motorolo
HF850 (it claims to support eSCO, but will actually reject eSCO connections
after 5 seconds) and the 2007/2008 Infiniti G35/37 (fails to route audio
if a 2-EV5 packet type is negiotiated). With this patch userspace can maintain
a list of compatible packet types to workaround remote devices such as these.

Based on a patch by Marcel Holtmann.

Rebased to 2.6.39.

With this patch we will retry with a SCO connection, which succeeds.

Unfortunately the Moto HF850 also takes 5 seconds to return the error for the
eSCO attempt, so it will still take 5 seconds to fallback to SCO with this
patch.

8f984dfaf0 Bluetooth: Remove redundant read_host_features commands
Previously the write_le_enable would trigger a read_host_features
command but since we have access to the value LE support was set to we
can simply just clear or set the bit in hdev->host_features. This also
removes a second unnecessary read_host_features command from the device
initialization procedure since LE is only enabled after the first
read_host_features command completes.

3159d3843a Bluetooth: Fix init request completion with old controllers
With Bluetooth 1.1 controllers the last command in the HCI init sequence
will be a write_local_name, however there was no callback to indicate
init request completion in this case. This patch fixes the issue by
adding the necessary callback to the write_local_name_complete handler.
