2015-03-13Bluetooth: Merge hdev->dbg_flags fields into hdev->dev_flagsMarcel Holtmann
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. Signed-off-by: Marcel Holtmann <marcel@holtmann.org> Signed-off-by: Johan Hedberg <johan.hedberg@intel.com>

2015-03-11Bluetooth: Check for matching IRK when looking for paired LE devicesJohan Hedberg
If we're given an RPA when checking whether we're paired or not, we should consult the local RPA storage whether there's a matching IRK. This we we ensure that hci_bdaddr_is_paired() gives the right result even when trying to pair a second time with the same device with an RPA.

2015-03-10Bluetooth: Make Fast Connectable available while powered offJohan Hedberg
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.

2015-03-07Bluetooth: fix sco_exit compile warningAlexander Aring
While compiling the following warning occurs: WARNING: net/built-in.o(.init.text+0x602c): Section mismatch in reference from the function bt_init() to the function .exit.text:sco_exit() The function __init bt_init() references a function __exit sco_exit(). This is often seen when error handling in the init function uses functionality in the exit path. The fix is often to remove the __exit annotation of sco_exit() so it may be used outside an exit section. Since commit 6d785aa345f525e1fdf098b7c590168f0b00f3f1 ("Bluetooth: Convert mgmt to use HCI chan registration API") the function "sco_exit" is used inside of function "bt_init".

2015-03-06Bluetooth: Add mgmt_send_event() helper to send to any HCI channelJohan Hedberg
Currently the mgmt_event() function is only capable of sending to HCI_CHANNEL_CONTROL. To void having to change all users of it, add a new mgmt_send_event() function that takes a channel parameter, and make the old mgmt_event() a wrapper that passes MGMT_CHANNEL_CONTROL to it.

2015-03-06Bluetooth: Rename pending_cmd to mgmt_pending_cmdJohan Hedberg

2015-03-06Bluetooth: Move all mgmt command quirks to handler tableJohan Hedberg
In order to completely generalize the mgmt command handling we need to move away command-specific information from mgmt_control() into the actual command table. This patch adds a new 'flags' field to the handler entries which can now contain the following command specific information: - Command takes variable length parameters - Command doesn't target any specific HCI device - Command can be sent when the HCI device is unconfigured After this the mgmt_control() function is completely generic and can potentially be reused by new HCI channels.

2015-03-06Bluetooth: Introduce controller setting information for static addressMarcel Holtmann
Currently it is not possible to determine if the static address is used by the controller. It is also not possible to determine if using a static on a dual-mode controller with disabled BR/EDR is possible or not. To address this issue, introduce a new setting called static-address. If support for this setting is signaled that means that the kernel supports using static addresses. And if used on dual-mode controllers with BR/EDR disabled it means that a configured static address can be used. In addition utilize the same setting for the list of current active settings that indicates if a static address is configured and if that address will be actually used. With this in mind the existing Set Static Address management command has been extended to return the current settings. That way the caller of that command can easily determine if the programmed address will be used or if extra steps are required.

2015-03-05Bluetooth: fix service discovery behaviour for empty uuids filterJakub Pawlowski
This patch fixes service discovery behaviour, when provided uuid filter is empty and HCI_QUIRK_STRICT_DUPLICATE_FILTER is set. Before this patch, empty uuid filter was unable to trigger scan restart, and that caused inconsistent behaviour in applications. Example: two DBus clients call BlueZ, one to find all devices with service abcd, second to find all devices with rssi smaller than -90. Sum of those filters, that is passed to mgmt_service_scan is empty filter, with no rssi or uuids set. That caused kernel not to restart scan when quirk was set. That was inconsistent with what happen when there's only one of those two filters set (scan is restarted and reports devices). To fix that, new variable hdev->discovery.result_filtering was introduced. It can indicate that filtered scan is running, no matter what uuid or rssi filter is set.

2015-03-05Bluetooth: Refactor service discovery filter logicJakub Pawlowski
This patch refactor code responsible for filtering when service discovery method is used. Previously this code was mixed with mgmt_device found logic. Now when it's in one place whole logic can be greatly simplified. That includes removing no longer necessary length field and merging checks for eir and scan_rsp.

2015-03-05Bluetooth: Move Service Discovery logic before refactoringJakub Pawlowski
This patch moves whole packet filering logic of service discovery into new function is_filter_match. It's done because logic inside mgmt_device_found is very complicated and needs some simplification. Also having whole logic in one place will allow to simplify it in the future.

2015-02-20Bluetooth: Use hci_copy_identity_addr() helper for SMP chan creationJohan Hedberg
The only reason the SMP code is essentially duplicating the hci_copy_identity_addr() function is that the helper returns the address type in the HCI format rather than the three-value format expected by l2cap_chan.

2015-02-16Bluetooth: Fix accepting early data on fixed channelsJohan Hedberg
On BR/EDR the L2CAP channel instances for fixed channels have so far been marked as ready only once the L2CAP information req/rsp procedure is complete and we have the fixed channel mask. This could however lead to data being dropped if we receive it on the channel before knowing the remote mask. Since it is valid for a remote to send data this early, simply assume that the channel is supported when we receive data on it. So far this hasn't been noticed much because of limited use of fixed channels on BR/EDR, but e.g. with SMP over BR/EDR this is already now visible with automated tests failing randomly.
