2011-07-11Bluetooth: Add support for storing the key sizeVinicius Costa Gomes
In some cases it will be useful having the key size used for encrypting the link. For example, some profiles may restrict some operations depending on the key length. The key size is stored in the key that is passed to userspace using the pin_length field in the key structure. For now this field is only valid for LE controllers. 3.0+HS controllers define the Read Encryption Key Size command, this field is intended for storing the value returned by that command.

2011-07-11Bluetooth: Add support for communicating keys with userspaceVinicius Costa Gomes
As the key format has changed to something that has a dynamic size, the way that keys are received and sent must be changed. The structure fields order is changed to make the parsing of the information received from the Management Interface easier.

2011-06-14Bluetooth: Allow SCO/eSCO packet type selection for outgoing SCO connections.Nick Pelly
__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.
