* Bluetooth: Use bt_dev_err and bt_dev_info when possibleMarcel Holtmann2017-10-301-26/+30
| | | | | | | | | In case of using BT_ERR and BT_INFO, convert to bt_dev_err and bt_dev_info when possible. This allows for controller specific reporting. Signed-off-by: Marcel Holtmann <marcel@holtmann.org> Signed-off-by: Johan Hedberg <johan.hedberg@intel.com>
* Bluetooth: Fix potential memory leakJaganath Kanakkassery2017-10-291-0/+1
| | | | | | | | | | | | | | | If command is added to req then it should be freed in case if hdev is down or HCI_ADVERTISING flag is set. This introduces a helper in hci_request to purge the cmd_q to make cmd_q internal to hci_request which is used to fix the leak. This also replace accessing of cmd_q in hci_conn with the new helper.

* Bluetooth: Fix append max 11 bytes of name to scan rsp dataMichał Narajowski2016-10-191-9/+17
| | | | | | | | | | | Append maximum of 10 + 1 bytes of name to scan response data. Complete name is appended only if exists and is <= 10 characters. Else append short name if exists or shorten complete name if not. This makes sure name is consistent across multiple advertising instances.

* Bluetooth: Fix NULL pointer dereference in mgmt contextArek Lichwa2016-09-221-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Adds missing callback assignment to cmd_complete in pending management command context. Dump path involves security procedure performed on legacy (pre-SSP) devices with service security requirements set to HIGH (16digits PIN). It fails when shorter PIN is delivered by user.

* Bluetooth: mgmt: Fix sending redundant event for Advertising InstanceJohan Hedberg2016-09-191-3/+3
| | | | | | | | | | | | | | When an Advertising Instance is removed, the Advertising Removed event shouldn't be sent to the same socket that issued the Remove Advertising command (it gets a command complete event instead). The mgmt_advertising_removed() function already has a parameter for skipping a specific socket, but there was no code to propagate the right value to this parameter. This patch fixes the issue by making sure the intermediate hci_req_clear_adv_instance() function gets the socket pointer.

* Bluetooth: Rename HCI_BREDR into HCI_PRIMARYMarcel Holtmann2016-07-091-8/+8
| | | | | | | | | | | | | | 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: Fix potential buffer overflow with Add AdvertisingJohan Hedberg2016-03-111-0/+4
| | | | | | | | | | | | | The Add Advertising command handler does the appropriate checks for the AD and Scan Response data, however fails to take into account the general length of the mgmt command itself, which could lead to potential buffer overflows. This patch adds the necessary check that the mgmt command length is consistent with the given ad and scan_rsp lengths.

| | | | | | | | | | | | 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.

* Bluetooth: Clean up current advertising instance trackingJohan Hedberg2015-12-101-4/+6
| | | | | | | | | | | | | We can simplify a lot of code by making sure hdev->cur_adv_instance is always up-to-date. This allows e.g. the removal of the get_current_adv_instance() helper function and the special HCI_ADV_CURRENT value.

* Bluetooth: Perform HCI update for power on synchronouslyJohan Hedberg2015-12-101-128/+8
| | | | | | | | | | | | | | | | | | | | 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 Hedberg2015-12-101-39/+2

* Bluetooth: Move discoverable changes to hdev->req_workqueueJohan Hedberg2015-12-101-77/+13
| | | | | | | | | | 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 advertising instance management to hci_request.cJohan Hedberg2015-12-101-534/+40
| | | | | | | | | | 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 Hedberg2015-12-101-8/+8
| | | | | | | | | | | | | | | | 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: Fix powering on with privacy and advertisingAndrzej Kaczmarek2015-11-231-7/+7
| | | | | | | | | | | | | | | | In order to enable advertising with privacy enabled, SMP has to be registered in order to generate new RPA. During power on, it will be registered at the very end which is the reason why advertising is not enabled and it's not possible to enable it anymore due to mismatch between hci_dev settings and actual controller state. This fixes this problem by moving SMP registration earlier, just after controller is powered (which is ok, because LE SMP will be already able to decide on identity address to be used), but before advertising is enabled.

| | | | | | | | | | 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>
