* Bluetooth: Add support for limited privacy modeJohan Hedberg2016-03-101-0/+1
| | | | | | | | | | | | Introduce a limited privacy mode indicated by value 0x02 to the mgmt Set Privacy command. With value 0x02 the kernel will use privacy mode with a resolvable private address. In case the controller is bondable and discoverable the identity address will be used. Signed-off-by: Johan Hedberg <johan.hedberg@intel.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
* Bluetooth: Remove unnecessary HCI_ADVERTISING_INSTANCE flagJohan Hedberg2015-12-101-1/+0
| | | | | | | | | This flag just tells us whether hdev->adv_instances is empty or not. We can equally well use the list_empty() function to get this information. Signed-off-by: Johan Hedberg <johan.hedberg@intel.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
* Bluetooth: Add HCI status return parameter to hci_req_sync()Johan Hedberg2015-11-191-1/+2
| | | | | | | | | | | In some cases it may be important to get the exact HCI status rather than the converted HCI-to-errno value. Add an optional return parameter to the hci_req_sync() API to allow for this. Since there are no good HCI translation candidates for cancelation and timeout, use the "unknown" status code for those cases.

* Bluetooth: Add support setup stage internal notification eventMarcel Holtmann2015-10-211-0/+1
| | | | | | | | | | | | Before the vendor specific setup stage is triggered call back into the core to trigger an internal notification event. That event is used to send an index update to the monitor interface. With that specific event it is possible to update userspace with manufacturer information before any HCI command has been executed. This is useful for early stage debugging of vendor specific initialization sequences. Signed-off-by: Marcel Holtmann <marcel@holtmann.org> Signed-off-by: Johan Hedberg <johan.hedberg@intel.com>
* Bluetooth: Add new quirk for non-persistent diagnostic settingsMarcel Holtmann2015-10-211-0/+9
| | | | | | | | | | If the diagnostic settings are not persistent over HCI Reset, then this quirk can be used to tell the Bluetoth core about it. This will ensure that the settings are programmed correctly when the controller is powered up.

* Bluetooth: Add debugfs entry for setting vendor diagnostic modeMarcel Holtmann2015-10-081-0/+1
| | | | | | | | | | This adds a new debugfs entry for enabling and disabling the vendor diagnostic mode. It is only exposed for drivers that provide the set_diag driver callback and actually have an option for vendor specific diagnostic information.

* Bluetooth: Add support for vendor specific diagnostic channelMarcel Holtmann2015-10-081-0/+1
| | | | | | | | | | Introduce hci_recv_diag function for HCI drivers to allow sending vendor specific diagnostic messages into the Bluetooth core stack. The messages are not processed, but they are forwarded to the monitor channel and can be retrieved by user space diagnostic tools.

* Bluetooth: Read encryption key size for BR/EDR connectionsJohan Hedberg2015-06-121-0/+10
| | | | | | | | | | Since Bluetooth 3.0 there's a HCI command available for reading the encryption key size of an BR/EDR connection. This information is essential e.g. for generating an LTK using SMP over BR/EDR, so store it as part of struct hci_conn.

* Bluetooth: Read LE remote features during connection establishmentMarcel Holtmann2015-04-091-0/+13
| | | | | | | | | | | | | | | | When establishing a Bluetooth LE connection, read the remote used features mask to determine which features are supported. This was not really needed with Bluetooth 4.0, but since Bluetooth 4.1 and also 4.2 have introduced new optional features, this becomes more important. This works the same as with BR/EDR where the connection enters the BT_CONFIG stage and hci_connect_cfm call is delayed until the remote features have been retrieved. Only after successfully receiving the remote features, the connection enters the BT_CONNECTED state.

* Bluetooth: Update SSP OOB data EIR definitionsJohan Hedberg2015-04-071-2/+4
| | | | | | | | | Since Bluetooth 4.1 there are two additional values for SSP OOB data, namely C-256 and R-256. This patch updates the EIR definitions to take into account both the 192 and 256 bit variants of C and R.

* Bluetooth: Introduce HCI_QUIRK_SIMULTANEOUS_DISCOVERYJakub Pawlowski2015-03-171-0/+8
| | | | | | | | | | | | | Some controllers allow both LE scan and BR/EDR inquiry to run at the same time, while others allow only one, LE SCAN or BR/EDR inquiry at given time. Since this is specific to each controller, add a new quirk setting that allows drivers to tell the core wether given controller can do both LE scan and BR/EDR inquiry at same time.

* Bluetooth: Add support for Local OOB Extended Data Update eventsMarcel Holtmann2015-03-171-0/+1
| | | | | | | | | | When a different user requests a new set of local out-of-band data, then inform all previous users that the data has been updated. To limit the scope of users, the updates are limited to previous users. If a user has never requested out-of-band data, it will also not see the update.

* Bluetooth: Send global configuration updates to all management usersMarcel Holtmann2015-03-151-0/+1
| | | | | | | | | | | Changes to the global configuration updates like settings, class of device, name etc. can be received by every user. They are allowed to read them in the first place so provide the updates via events as well. Otherwise untrusted users start polling for updates and that is not a desired behavior.

* Bluetooth: Introduce trusted flag for management control socketsMarcel Holtmann2015-03-151-0/+1
| | | | | | | | | Providing a global trusted flag for management control sockets provides an easy way for identifying sockets and imposing restriction on it. For now all management sockets are trusted since they require CAP_NET_ADMIN. Signed-off-by: Marcel Holtmann <marcel@holtmann.org> Signed-off-by: Johan Hedberg <johan.hedberg@intel.com>
* Bluetooth: Add support for extended index management eventsMarcel Holtmann2015-03-151-0/+1

* Bluetooth: Merge hdev->dbg_flags fields into hdev->dev_flagsMarcel Holtmann2015-03-131-9/+5
| | | | | | | | | | With the extension of hdev->dev_flags utilizing a bitmap now, the space is no longer restricted. Merge the hdev->dbg_flags into hdev->dev_flags to save space on 64-bit architectures. On 32-bit architectures no size reduction happens.

* Bluetooth: Make Fast Connectable available while powered offJohan Hedberg2015-03-101-1/+1
| | | | | | | | | | | | | To maximize the usability of the Fast Connectable feature we should make it possible to set (or unset) it at any given moment. This means removing the dependency on the 'connectable' setting as well as the 'powered' setting. The former makes also sense since page scan may get enabled through add_device even if 'connectable' is false. To keep the setting available over power cycles its flag also needs to be removed from the flags that are cleared upon HCI_Reset.

* Bluetooth: Remove broken force_lesc_support debugfs optionMarcel Holtmann2015-01-021-1/+0
| | | | | | | | | | | | The force_lesc_support debugfs option never really worked. It has a race condition between creating the debugfs entry and registering the L2CAP fixed channel for BR/EDR SMP support. Also this has been replaced with a working force_bredr_smp debugfs switch that developers can use now.

* Bluetooth: Introduce force_bredr_smp debugfs option for testingMarcel Holtmann2015-01-021-0/+1
| | | | | | | | | | | | Testing cross-transport pairing that starts on BR/EDR is only valid when using a controller with BR/EDR Secure Connections. Devices will indicate this by providing BR/EDR SMP fixed channel over L2CAP. To allow testing of this feature on Bluetooth 4.0 controller or controllers without the BR/EDR Secure Connections features, introduce a force_bredr_smp debugfs option that allows faking the required AES connection.

* Bluetooth: Introduce HCI_QUIRK_BROKEN_LOCAL_COMMANDS constantMarcel Holtmann2014-12-261-0/+10
| | | | | | | | | | | | Some controllers advertise support for Bluetooth 1.2 specification, but they do not support the HCI Read Local Supported Commands command. If that is the case, then the driver can quirk the behavior and force the core to skip this command. This will allow removing vendor specific checks out of the core.

* Bluetooth: Enabled LE Direct Advertising Report event if supportedMarcel Holtmann2014-12-051-0/+1
| | | | | | | | | | When the controller supports the Extended Scanner Filter Policies, it supports the LE Direct Advertising Report event.

* Bluetooth: Add debugfs switch for forcing SMP over BR/EDRJohan Hedberg2014-12-031-0/+1
| | | | | | | | | | | To make it possible to use LE SC functionality over BR/EDR with pre-4.1 controllers (that do not support BR/EDR SC links) it's useful to be able to force LE SC operations even over a traditional SSP protected link. This patch adds a debugfs switch to force a special debug flag which is used to skip the checks for BR/EDR SC support.

* Bluetooth: Use shorter "rand" name for "randomizer"Johan Hedberg2014-11-181-6/+6
| | | | | | | | | | | The common short form of "randomizer" is "rand" in many places (including the Bluetooth specification). The shorter version also makes for easier to read code with less forced line breaks. This patch renames all occurences of "randomizer" to "rand" in the Bluetooth subsystem code.

* Bluetooth: Add hci_conn_lookup_type() helper functionMarcel Holtmann2014-11-031-0/+1

* Bluetooth: Introduce HCI_QUIRK_STRICT_DUPLICATE_FILTERMarcel Holtmann2014-11-031-0/+9
| | | | | | | | | | | | | | Some vendors decide to use a strict duplicate filter policy that only filters on Bluetooth device addresses. This means that when the RSSI changes, these devices are not reported again. During discovery it is useful to actually get the RSSI updates. Since this is specific to each controller, add a new quirk setting that allows drivers to tell the core what kind of filtering policy the controller uses.

* Bluetooth: Fix reason code used for rejecting SCO connectionsJohan Hedberg2014-09-241-0/+1
| | | | | | | | | | | | | | | | | | | | | | | The core specification defines valid values for the HCI_Reject_Synchronous_Connection_Request command to be 0x0D-0x0F. So far the code has been using HCI_ERROR_REMOTE_USER_TERM (0x13) which is not a valid value and is therefore being rejected by some controllers: > HCI Event: Connect Request (0x04) plen 10 bdaddr 40:6F:2A:6A:E5:E0 class 0x000000 type eSCO < HCI Command: Reject Synchronous Connection (0x01|0x002a) plen 7 bdaddr 40:6F:2A:6A:E5:E0 reason 0x13 Reason: Remote User Terminated Connection > HCI Event: Command Status (0x0f) plen 4 Reject Synchronous Connection (0x01|0x002a) status 0x12 ncmd 1 Error: Invalid HCI Command Parameters This patch introduces a new define for a value from the valid range (0x0d == Connection Rejected Due To Limited Resources) and uses it instead for rejecting incoming connections.

* Bluetooth: Add proper defines for HCI connection roleJohan Hedberg2014-07-161-3/+3
| | | | | | | | | | All HCI commands and events, including LE ones, use 0x00 for master role and 0x01 for slave role.
