The Start_Synchronization_Train command controls the Synchronization Train functionality in the BR/EDR Controller. The Core Spec Addendum 4 adds this command in part B Connectionless Slave Broadcast. Bluetooth Core Specification Addendum 4 - Page 86 "7.1.51 Start Synchronization Train Command [New Section] ... If connectionless slave broadcast mode is not enabled, the Command Disallowed (0x0C) error code shall be returned. After receiving this command and returning a Command Status event, the Baseband starts attempting to send synchronization train packets containing information related to the enabled Connectionless Slave Broadcast packet timing. Note: The AFH_Channel_Map used in the synchronization train packets is configured by the Set_AFH_Channel_Classification command and the local channel classification in the BR/EDR Controller. The synchronization train packets will be sent using the parameters specified by the latest Write_Synchronization_Train_Parameters command. The Synchronization Train will continue until synchronization_trainTO slots (as specified in the last Write_Synchronization_Train command) have passed or until the Host disables the Connectionless Slave Broadcast logical transport."

We shouldn't include the simultaneous LE & BR/EDR flags in the LE advertising data if BR/EDR is disabled on a dual-mode controller. This patch fixes this issue and ensures that the create_ad function generates the correct flags when BR/EDR is disabled. Signed-off-by:

The REJECTED management response should mainly be used when the adapter is in a state where we cannot accept some command or a specific parameter value. The NOT_SUPPORTED response in turn means that the adapter really cannot support the command or parameter value. This patch fixes this distinction and adds two helper functions to easily get the appropriate LE or BR/EDR related status response. Signed-off-by:

On dual-mode BR/EDR/LE and LE only controllers it is possible to configure a random address. There are two types or random addresses, one is static and the other private. Since the random private addresses require special privacy feature to be supported, the configuration of these two are kept separate. This command allows for setting the static random address. It is only supported on controllers with LE support. The static random address is suppose to be valid for the lifetime of the controller or at least until the next power cycle. To ensure such behavior, setting of the address is limited to when the controller is powered off. The special BDADDR_ANY address (00:00:00:00:00:00) can be used to disable the static address. This is also the default value. Signed-off-by:

Disabling the high speed setting when the controller is powered on has too many side effects that are not taken care of. And in general it is not an useful operation anyway. So just make such a command fail with a rejection error message. Signed-off-by:

This patch introduces a new mgmt command for enabling/disabling BR/EDR functionality. This can be convenient when one wants to make a dual-mode controller behave like a single-mode one. The command is only available for dual-mode controllers and requires that LE is enabled before using it. The BR/EDR setting can be enabled at any point, however disabling it requires the controller to be powered off (otherwise a "rejected" response will be sent). Disabling the BR/EDR setting will automatically disable all other BR/EDR related settings. Signed-off-by:

To allow treating dual-mode (BR/EDR/LE) controllers as single-mode ones (LE-only) we want to introduce a new HCI_BREDR_ENABLED flag to track whether BR/EDR is enabled or not (previously we simply looked at the feature bit with lmp_bredr_enabled). This patch add the new flag and updates the relevant places to test against it instead of using lmp_bredr_enabled. The flag is by default enabled when registering an adapter and only cleared if necessary once the local features have been read during the HCI init procedure. We cannot completely block BR/EDR usage in case user space uses raw HCI sockets but the patch tries to block this in places where possible, such as the various BR/EDR specific ioctls. Signed-off-by:

When hci_sock.c calls hci_dev_open it needs to ensure that there isn't pending work in progress, such as that which is scheduled for the initial setup procedure or the one for automatically powering off after the setup procedure. This adds the necessary calls to ensure that any previously scheduled work is completed before attempting to call hci_dev_do_open. This patch fixes a race with old user space versions where we might receive a HCIDEVUP ioctl before the setup procedure has been completed. When that happens the setup procedures callback may fail early and leave the device in an inconsistent state, causing e.g. the setup callback to be (incorrectly) called more than once. Signed-off-by:

The requirements of an external call to hci_dev_open from hci_sock.c are different to that from within hci_core.c. In the former case we want to flush any pending work in hdev->req_workqueue whereas in the latter we don't (since there we are already calling from within the workqueue itself). This patch does the necessary refactoring to a separate hci_dev_do_open function (analogous to hci_dev_do_close) but does not yet introduce the synchronizations relating to the workqueue usage.

Hiding the Bluetooth high speed support behind a module parameter is not really useful. This can be enabled and disabled at runtime via the management interface. This also has the advantage that this can now be changed per controller and not just global. This patch removes the module parameter and exposes the high speed setting of the management interface to all controllers. Signed-off-by:

This patch adds a new mgmt command for enabling and disabling LE advertising. The command depends on the LE setting being enabled first and will return a "rejected" response otherwise. The patch also adds safeguards so that there will ever only be one set_le or set_advertising command pending per adapter. The response handling and new_settings event sending is done in an asynchronous request callback, meaning raw HCI access from user space to enable advertising (e.g. hciconfig leadv) will not trigger the new_settings event. This is intentional since trying to support mixed raw HCI and mgmt access would mean adding extra state tracking or new helper functions, essentially negating the benefit of using the asynchronous request framework. The HCI_LE_ENABLED and HCI_LE_PERIPHERAL flags however are updated correctly even with raw HCI access so this will not completely break subsequent access over mgmt. Signed-off-by:

This patch adds a new mgmt setting for LE advertising and hooks up the necessary places in the mgmt code to operate on the HCI_LE_PERIPHERAL flag (which corresponds to this setting). This patch does not yet add any new command for enabling the setting - that is left for a subsequent patch. Signed-off-by:

This patch updates the code to use an asynchronous request for handling the enabling and disabling of LE support. This refactoring is necessary as a preparation for adding advertising support, since when LE is disabled we should also disable advertising, and the cleanest way to do this is to perform the two respective HCI commands in the same asynchronous request.

Johan Hedberg authored
The settings_rsp and cmd_status_rsp functions can be useful for all mgmt command handlers when asynchronous request callbacks are used. They will e.g. be used by subsequent patches to change set_le to use an async request as well as a new set_advertising command. Therefore, move them higher up in the mgmt.c file to avoid unnecessary forward declarations or mixing this trivial change with other patches. Signed-off-by:

We should return a "busy" error always when there is another mgmt_set_powered operation in progress. Previously when powering on while the auto off timer was still set the code could have let two or more pending power on commands to be queued. This patch fixes the issue by moving the check for duplicate commands to an earlier point in the set_powered handler. Signed-off-by:

When the dlc is closed, rfcomm_dev_state_change() tries to release the port in the case it cannot get a reference to the tty. However this is racy and not even needed. Infact as Peter Hurley points out: 1. Only consider dlcs that are 'stolen' from a connected socket, ie. reused. Allocated dlcs cannot have been closed prior to port activate and so for these dlcs a tty reference will always be avail in rfcomm_dev_state_change() -- except for the conditions covered by #2b below. 2. If a tty was at some point previously created for this rfcomm, then either (a) the tty reference is still avail, so rfcomm_dev_state_change() will perform a hangup. So nothing to do, or, (b) the tty reference is no longer avail, and the tty_port will be destroyed by the last tty_port_put() in rfcomm_tty_cleanup. Again, no action required. 3. Prior to obtaining the dlc lock in rfcomm_dev_add(), rfcomm_dev_state_change() will not 'see' a rfcomm_dev so nothing to do here. 4. After releasing the dlc lock in rfcomm_dev_add(), rfcomm_dev_state_change() will 'see' an incomplete rfcomm_dev if a tty reference could not be obtained. Again, the best thing to do here is nothing. Any future attempted open() will block on rfcomm_dev_carrier_raised(). The unconnected device will exist until released by ioctl(RFCOMMRELEASEDEV). The patch removes the aforementioned code and uses the tty_port_tty_hangup() helper to hangup the tty. Signed-off-by:Gianluca Anzolin <gianluca@sottospazio.it> Reviewed-by:

This patch adds support for reading the synchronization train parameters for controllers that support the feature. Since the feature is detectable through the local features page 2, which is retreived only in stage 3 of the HCI init sequence, there is no other option than to add a fourth stage to the init sequence. For now the patch doesn't yet add storing of the parameters, but it is nevertheless convenient to have around to see what kind of parameters various controllers use by default (analyzable e.g. with the btmon user space tool).
