* Bluetooth: Add tracking of local and piconet clock valuesJohan Hedberg2014-07-03
| | | | | | | | | | This patch adds support for storing the local and piconet clock values from the HCI_Read_Clock command response to the hci_dev and hci_conn structs. This will be later used in another patch to implement support for the Get Clock Info mgmt command.

* Bluetooth: Send HCI_Read_Clock_Offset before disconnectingMarcel Holtmann2014-07-03
| | | | | | | | | | When the connection is in master role and it is going to be disconnected based on the disconnection timeout, then send the HCI_Read_Clock_Offset command in an attempt to update the clock offset value in the inquiry cache.

* Bluetooth: Add a new HCI_USE_DEBUG_KEYS flagJohan Hedberg2014-07-03
| | | | | | | | | | | To pave the way for actively using debug keys for pairing this patch adds a new HCI_USE_DEBUG_KEYS flag for the purpose. When the flag is set we issue a HCI_Write_SSP_Debug mode whenever HCI_Write_SSP_Mode(0x01) has been issued as well as before issuing a HCI_Write_SSP_Mode(0x00) command.

* Bluetooth: Rename HCI_DEBUG_KEYS to HCI_KEEP_DEBUG_KEYSJohan Hedberg2014-07-03
| | | | | | | | | | | We're planning to add a flag to actively use debug keys in addition to simply just accepting them, which makes the current generically named DEBUG_KEYS flag a bit confusing. Since the flag in practice affects whether the kernel keeps debug keys around or not rename it to HCI_KEEP_DEBUG_KEYS.

* Bluetooth: Track LE connection parameter update eventMarcel Holtmann2014-07-03
| | | | | | | | | | When the LE controller changes its connection parameters, it will send a connection parameter update event. Make sure that the new set of parameters are stored in hci_conn struct and thus will properly update the previous values retrieved from the connection complete event.

* Bluetooth: Remove unused LTK authentication definesJohan Hedberg2014-07-03
| | | | | | | | | These defines were probably put in to track authenticated vs unauthenticated LTKs, however since the LTK struct has a separate boolean authenticated member these were never used.

* Bluetooth: Remove HCI prefix from SMP LTK definesJohan Hedberg2014-07-03
| | | | | | | | | The LTK type has really nothing to do with HCI so it makes more sense to have these in smp.h than hci.h. This patch moves the defines to smp.h and removes the HCI_ prefix in the same go. Signed-off-by: Johan Hedberg <johan.hedberg@intel.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
* Bluetooth: Remove unnecessary SMP STK defineJohan Hedberg2014-07-03
| | | | | | | | | | We never store the "master" type of STKs since we request encryption directly with them so we only need one STK type (the one that's looked-up on the slave side). Simply remove the unnecessary define and rename the _SLAVE one to the shorter form. Signed-off-by: Johan Hedberg <johan.hedberg@intel.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>

* Bluetooth: Add directed advertising support through connect()Johan Hedberg2014-03-26
| | | | | | | | | | | | | When we're in peripheral mode (HCI_ADVERTISING flag is set) the most natural mapping of connect() is to perform directed advertising to the peer device. This patch does the necessary changes to enable directed advertising and keeps the hci_conn state as BT_CONNECT in a similar way as is done for central or BR/EDR connection initiation.

* Bluetooth: Remove unnecessary stop_scan_complete functionJohan Hedberg2014-02-28
| | | | | | | | | | | | | | | The stop_scan_complete function was used as an intermediate step before doing the actual connection creation. Since we're using hci_request there's no reason to have this extra function around, i.e. we can simply put both HCI commands into the same request. The single task that the intermediate function had, i.e. indicating discovery as stopped is now taken care of by a new HCI_LE_SCAN_INTERRUPTED flag which allows us to do the discovery state update when the stop scan command completes.

* Bluetooth: Add timeout for LE connection attemptsJohan Hedberg2014-02-28
| | | | | | | | | | | | | | | LE connection attempts do not have a controller side timeout in the same way as BR/EDR has (in form of the page timeout). Since we always do scanning before initiating connections the attempts are always expected to succeed in some reasonable time. This patch adds a timer which forces a cancellation of the connection attempt within 20 seconds if it has not been successful by then. This way we e.g. ensure that mgmt_pair_device times out eventually and gives an error response.

* Bluetooth: Use __le64 type for LE random numbersMarcel Holtmann2014-02-28
| | | | | | | | | | | The random numbers in Bluetooth Low Energy are 64-bit numbers and should also be little endian since the HCI specification is little endian.

* Bluetooth: Add timer to force power offJohan Hedberg2014-02-28
| | | | | | | | | | | If some of the cleanup commands caused by mgmt_set_powered(off) never complete we should still force the adapter to be powered down. This is rather easy to do since hdev->power_off is already a delayed work struct. This patch schedules this delayed work if at least one HCI command was sent by the cleanup procedure.

* Bluetooth: Stop scanning on LE connectionAndre Guedes2014-02-26
| | | | | | | | | | | | | | | | | | | | | | | | Some LE controllers don't support scanning and creating a connection at the same time. So we should always stop scanning in order to establish the connection. Since we may prematurely stop the discovery procedure in favor of the connection establishment, we should also cancel hdev->le_scan_ disable delayed work and set the discovery state to DISCOVERY_STOPPED. This change does a small improvement since it is not mandatory the user stops scanning before connecting anymore. Moreover, this change is required by upcoming LE auto connection mechanism in order to work properly with controllers that don't support background scanning and connection establishment at the same time. In future, we might want to do a small optimization by checking if controller is able to scan and connect at the same time. For now, we want the simplest approach so we always stop scanning (even if the controller is able to carry out both operations).

* Bluetooth: Replace own_address_type with force_static_address debugfsMarcel Holtmann2014-02-20
| | | | | | | | | | | | | | The own_address_type debugfs option does not providing enough flexibity for interacting with the upcoming LE privacy support. What really is needed is an option to force using the static address compared to the public address. The new force_static_address debugfs option does exactly that. In addition it is also only available when the controller does actually have a public address. For single mode LE only controllers this option will not be available.

* Bluetooth: Introduce requirements for security level 4Marcel Holtmann2014-02-13
| | | | | | | | | | | | | | | | | | | | | | The security level 4 is a new strong security requirement that is based around 128-bit equivalent strength for link and encryption keys required using FIPS approved algorithms. Which means that E0, SAFER+ and P-192 are not allowed. Only connections created with P-256 resulting from using Secure Connections support are allowed. This security level needs to be enforced when Secure Connection Only mode is enabled for a controller or a service requires FIPS compliant strong security. Currently it is not possible to enable either of these two cases. This patch just puts in the foundation for being able to handle security level 4 in the future. It should be noted that devices or services with security level 4 requirement can only communicate using Bluetooth 4.1 controllers with support for Secure Connections. There is no backward compatibilty if used with older hardware. Signed-off-by: Marcel Holtmann <marcel@holtmann.org> Signed-off-by: Johan Hedberg <johan.hedberg@intel.com>
* Bluetooth: Add debugfs quirk for forcing Secure Connections supportMarcel Holtmann2014-02-13
| | | | | | | | | | | | | | | | | | | The Bluetooth 4.1 specification with Secure Connections support has just been released and controllers with this feature are still in an early stage. A handful of controllers have already support for it, but they do not always identify this feature correctly. This debugfs entry allows to tell the kernel that the controller can be treated as it would fully support Secure Connections. Using debugfs to force Secure Connections support of course does not make this feature magically appear in all controllers. This is a debug functionality for early adopters. Once the majority of controllers matures this quirk will be removed. Signed-off-by: Marcel Holtmann <marcel@holtmann.org> Signed-off-by: Johan Hedberg <johan.hedberg@intel.com>

* Bluetooth: Add HCI command definition for extended OOB dataMarcel Holtmann2014-02-13
| | | | | | | | | | | | The Secure Connections feature introduces the support for P-256 strength pairings (compared to P-192 with Secure Simple Pairing). This however means that for out-of-band pairing the hash and randomizer needs to be differentiated. Two new commands are introduced to handle the possible combinations of P-192 and P-256.
