2011-12-02Bluetooth: Add dev_flags to struct hci_devAndre Guedes
This patch adds the dev_flags field to struct hci_dev. This new flags variable should be used to define flags related to BR/EDR and/or LE controller itself. It should be used to define flags which represents states from the controller. The dev_flags is cleared in case the controller sends a Reset Command Complete Event to the host. Also, this patch adds the HCI_LE_SCAN flag which was created to track if the controller is performing LE scan or not. The flag is set/cleared when the controller starts/stops scanning. This is an initial effort to stop using hdev->flags to define internal flags since it is exported to userspace by an ioctl.

2011-11-16Bluetooth: mgmt_stop_discovery_failed()Andre Guedes
This patches creates mgmt_stop_discovery_failed() which removes pending MGMT_OP_STOP_DISCOVERY commands and sends proper command status events.

2011-11-16Bluetooth: Rename mgmt_inquiry_failed()Andre Guedes
This patch renames the function mgmt_inquiry_failed() to mgmt_start_discovery_failed(). This function is more related to MGMT_OP_START_DISCOVERY command handling than to inquiry. Besides, this functions will be reused by LE based discovery procedures in case of failure.

2011-11-10Bluetooth: Add status parameter to mgmt_disconnect responseJohan Hedberg

2011-11-09Bluetooth: Add missing hci_dev locking when calling mgmt functionsJohan Hedberg

2011-11-09Bluetooth: Pass full hci_dev struct to mgmt callbacksJohan Hedberg
The current global pending command list in mgmt.c is racy. Possibly the simplest way to fix it is to have per-hci dev lists instead of a global one (all commands that need a pending struct are hci_dev specific). This way the list can be protected using the already existing per-hci dev lock. To enable this refactoring the first thing that needs to be done is to ensure that the mgmt functions have access to the hci_dev struct (instead of just the dev id).

2011-11-08Bluetooth: Add timeout field to mgmt_set_discoverableJohan Hedberg
Based on the revised mgmt API set_discoverable has a timeout parameter to specify how long the adapter will remain discoverable. A value of 0 means "indefinitively". Signed-off-by: Johan Hedberg <johan.hedberg@intel.com> Signed-off-by: Gustavo F. Padovan <padovan@profusion.mobi>
2011-11-08Bluetooth: Periodic Inquiry and DiscoveryAndre Guedes
By using periodic inquiry command we're not able to detect correctly when the controller has started inquiry. Today we have this workaround in inquiry result event handler to set the HCI_INQUIRY flag when it sees the first inquiry result event. This workaround isn't enough because the device may be performing an inquiry but the HCI_INQUIRY flag is not set. For instance, if there is no device in range, no inquiry result event is generated, consequently, the HCI_INQUIRY flags isn't set when it should so. We rely on HCI_INQUIRY flag to implement the discovery procedure properly. So, as we aren't able to clear/set the HCI_INQUIRY flag in a reliable manner, periodic inquiry events shouldn't change the HCI_INQUIRY flag. Thus, due to that issue and in order to keep compatibility with userspace, periodic inquiry events shouldn't send mgmt discovering events. In future, we might track if periodic inquiry is enabled or not. By tracking this state we'll be able to do some improvements in Discovery such as failing MGMT_OP_START_DISCOVERY command in case periodic inquiry is on. We can also send no mgmt_device_found event if periodic inquiry is on. Signed-off-by: Andre Guedes <andre.guedes@openbossa.org> Signed-off-by: Gustavo F. Padovan <padovan@profusion.mobi>

2011-09-21Bluetooth: Require authentication if MITM protection is requestedVinicius Costa Gomes
The HIGH security level requires a 16 digit pin code for non-SSP bondings. Sometimes this requirement is not acceptable and we still want protection againts MITM attacks (which is something that the MEDIUM security level doesn't provide), for that we should allow another way to request authentication without using the HIGH security level.

2011-09-21Bluetooth: Add link_type information to the mgmt Connected eventVinicius Costa Gomes

2011-07-08Bluetooth: 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.
