* Bluetooth: increase timeout for le auto connectionsKonrad Zapałowicz2017-10-291-1/+1
| | | | | | | | | | | | | This patch increases the connection timeout for LE connections that are triggered by the advertising report to 4 seconds. It has been observed that devices equipped with wifi+bt combo SoC fail to create a connection with BLE devices due to their coexistence issues. Increasing this timeout gives them enough time to complete the connection with success.

* Bluetooth: Fix using the correct source address typeJohan Hedberg2016-11-221-1/+1
| | | | | | | | | | | | | | The hci_get_route() API is used to look up local HCI devices, however so far it has been incapable of dealing with anything else than the public address of HCI devices. This completely breaks with LE-only HCI devices that do not come with a public address, but use a static random address instead. This patch exteds the hci_get_route() API with a src_type parameter that's used for comparing with the right address of each HCI device.

Many LE profiles define "PIN or Key Missing" status as indication of remote lost bond so this allows userspace to take action on this. @ Device Connected: 88:63:DF:88:0E:83 (1) flags 0x0000 02 01 1a 05 03 0a 18 0d 18 0b 09 48 65 61 72 74 ...........Heart 20 52 61 74 65 Rate > HCI Event: Command Status (0x0f) plen 4 LE Read Remote Used Features (0x08|0x0016) ncmd 1 Status: Success (0x00) > ACL Data RX: Handle 3585 flags 0x02 dlen 11 ATT: Read By Group Type Request (0x10) len 6 Handle range: 0x0001-0xffff Attribute group type: Primary Service (0x2800) > HCI Event: LE Meta Event (0x3e) plen 12 LE Read Remote Used Features (0x04) Status: Success (0x00) Handle: 3585 Features: 0x01 0x00 0x00 0x00 0x00 0x00 0x00 0x00 LE Encryption < HCI Command: LE Start Encryption (0x08|0x0019) plen 28 Handle: 3585 Random number: 0x0000000000000000 Encrypted diversifier: 0x0000 Long term key: 26201cd479a0921b6f949f0b1fa8dc82 > HCI Event: Command Status (0x0f) plen 4 LE Start Encryption (0x08|0x0019) ncmd 1 Status: Success (0x00) > HCI Event: Encryption Change (0x08) plen 4 Status: PIN or Key Missing (0x06) Handle: 3585 Encryption: Disabled (0x00) < HCI Command: Disconnect (0x01|0x0006) plen 3 Handle: 3585 Reason: Authentication Failure (0x05) > HCI Event: Command Status (0x0f) plen 4 Disconnect (0x01|0x0006) ncmd 1 Status: Success (0x00) > HCI Event: Disconnect Complete (0x05) plen 4 Status: Success (0x00) Handle: 3585 Reason: Connection Terminated By Local Host (0x16) @ Device Disconnected: 88:63:DF:88:0E:83 (1) reason 4 @ Device Connected: C4:43:8F:A3:4D:83 (0) flags 0x0000 08 09 4e 65 78 75 73 20 35 ..Nexus 5 > HCI Event: Command Status (0x0f) plen 4 Authentication Requested (0x01|0x0011) ncmd 1 Status: Success (0x00) > HCI Event: Link Key Request (0x17) plen 6 Address: C4:43:8F:A3:4D:83 (LG Electronics) < HCI Command: Link Key Request Reply (0x01|0x000b) plen 22 Address: C4:43:8F:A3:4D:83 (LG Electronics) Link key: 080812e4aa97a863d11826f71f65a933 > HCI Event: Command Complete (0x0e) plen 10 Link Key Request Reply (0x01|0x000b) ncmd 1 Status: Success (0x00) Address: C4:43:8F:A3:4D:83 (LG Electronics) > HCI Event: Auth Complete (0x06) plen 3 Status: PIN or Key Missing (0x06) Handle: 75 @ Authentication Failed: C4:43:8F:A3:4D:83 (0) status 0x05 < HCI Command: Disconnect (0x01|0x0006) plen 3 Handle: 75 Reason: Remote User Terminated Connection (0x13) > HCI Event: Command Status (0x0f) plen 4 Disconnect (0x01|0x0006) ncmd 1 Status: Success (0x00) > HCI Event: Disconnect Complete (0x05) plen 4 Status: Success (0x00) Handle: 75 Reason: Connection Terminated By Local Host (0x16) @ Device Disconnected: C4:43:8F:A3:4D:83 (0) reason 4 Signed-off-by: Szymon Janc <szymon.janc@codecoup.pl> Signed-off-by: Johan Hedberg <johan.hedberg@intel.com>
* Bluetooth: Rename HCI_BREDR into HCI_PRIMARYMarcel Holtmann2016-07-091-1/+1
| | | | | | | | | | | | | | The HCI_BREDR naming is confusing since it actually stands for Primary Bluetooth Controller. Which is a term that has been used in the latest standard. However from a legacy point of view there only really have been Basic Rate (BR) and Enhanced Data Rate (EDR). Recent versions of Bluetooth introduced Low Energy (LE) and made this terminology a little bit confused since Dual Mode Controllers include BR/EDR and LE. To simplify this the name HCI_PRIMARY stands for the Primary Controller which can be a single mode or dual mode controller.

* 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: add LED trigger for indicating HCI is powered upHeiner Kallweit2016-02-231-0/+3
| | | | | | | | | | Add support for LED triggers to the Bluetooth subsystem and add kernel config symbol BT_LEDS for it. For now one trigger for indicating "HCI is powered up" is supported. Signed-off-by: Heiner Kallweit <hkallweit1@gmail.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
* Bluetooth: L2CAP: Introduce proper defines for PSM rangesJohan Hedberg2016-01-291-0/+6
| | | | | | | | | Having proper defines makes the code a bit readable, it also avoids duplicating hard-coded values since these are also needed when auto-allocating PSM values (in a subsequent patch).

* Bluetooth: Add support for Start Limited Discovery commandJohan Hedberg2016-01-052-0/+3
| | | | | | | | | This patch implements the mgmt Start Limited Discovery command. Most of existing Start Discovery code is reused since the only difference is the presence of a 'limited' flag as part of the discovery state.

* Bluetooth: Change eir_has_data_type() to more generic eir_get_data()Johan Hedberg2016-01-051-10/+20
| | | | | | | | | To make the EIR parsing helper more general purpose, make it return the found data and its length rather than just saying whether the data was present or not. 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: Perform HCI update for power on synchronouslyJohan Hedberg2015-12-101-1/+2
| | | | | | | | | | | | | | | | | | | | The request to update HCI during power on is always coming either from hdev->req_workqueue or through an ioctl, so it's safe to use hci_req_sync for it. This way we also eliminate potential races with incoming mgmt commands or other actions while powering on. Part of this refactoring is the splitting of mgmt_powered() into mgmt_power_on() and __mgmt_power_off() functions. The main reason is the different requirements as far as hdev locking is concerned, as highlighted with the __ prefix of the power off API. Since the power on in the case of clearing the AUTO_OFF flag cannot be done synchronously in the set_powered mgmt handler, the hci_power_on work callback is extended to cover this (which also simplifies the set_powered helper a lot).

* Bluetooth: Move discoverable timeout behind hdev->req_workqueueJohan Hedberg2015-12-101-1/+0
| | | | | | | | Since the other discoverable changes are behind req_workqueue now it only makes sense to move the discoverable timeout there as well. Signed-off-by: Johan Hedberg <johan.hedberg@intel.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
* Bluetooth: Move discoverable changes to hdev->req_workqueueJohan Hedberg2015-12-101-0/+2
| | | | | | | | | | The discoverable mode is intrinsically linked with the connectable mode e.g. through sharing the same HCI command (Write Scan Enable) for BR/EDR. It makes therefore sense to move it to hci_request.c and run the changes through the same hdev->req_workqueue.

* Bluetooth: Move connectable changes to hdev->req_workqueueJohan Hedberg2015-12-101-0/+2
| | | | | | | | | | This way the connectable changes are synchronized against each other, which helps avoid potential races. The connectable mode is also linked together with LE advertising which makes is more convenient to have it behind the same workqueue.

* Bluetooth: Move advertising instance management to hci_request.cJohan Hedberg2015-12-101-3/+6
| | | | | | | | | | This paves the way for eventually performing advertising changes through the hdev->req_workqueue. Some new APIs need to be exposed from mgmt.c to hci_request.c and vice-versa, but many of them will go away once hdev->req_workqueue gets used.

* Bluetooth: Run page scan updates through hdev->req_workqueueJohan Hedberg2015-12-101-0/+1
| | | | | | | | | | | | | | | | Since Add/Remove Device perform the page scan updates independently from the HCI command completion we've introduced a potential race when multiple mgmt commands are queued. Doing the page scan updates through the req_workqueue ensures that the state changes are performed in a race-free manner. At the same time, to make the request helper more widely usable, extend it to also cover Inquiry Scan changes since those are behind the same HCI command. This is also reflected in the new name of the API as well as the work struct name. Signed-off-by: Johan Hedberg <johan.hedberg@intel.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
* Bluetooth: Add support for Get Advertising Size Information commandMarcel Holtmann2015-11-221-0/+13
| | | | | | | | | | The Get Advertising Size Information command allows to retrieve size information for advertising data and scan response data fields depending on the selected flags. This is useful if applications want to know the available size ahead of time. Signed-off-by: Marcel Holtmann <marcel@holtmann.org> Signed-off-by: Johan Hedberg <johan.hedberg@intel.com>
* Bluetooth: Fix specifying role for LE connectionsJohan Hedberg2015-11-191-1/+1
| | | | | | | | | | | The hci_connect_le_scan() is (as the name implies) a master/central role API, so it makes no sense in passing a role parameter to it. At the same time this patch also fixes the direct advertising support for LE L2CAP sockets where we now call the more appropriate hci_le_connect() API if slave/peripheral role is desired.

* Bluetooth: Move Stop Discovery to req_workqueueJohan Hedberg2015-11-191-0/+1
| | | | | | | | | | | | | | | Since discovery also deals with LE scanning it makes sense to move it behind the same req_workqueue as other LE scanning changes. This also simplifies the logic since we do many of the actions in a synchronous manner. Part of this refactoring is moving hci_req_stop_discovery() to hci_request.c. At the same time the function receives support for properly handling the STOPPING state since that's the state we'll be in when stopping through the req_workqueue.

* 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.
