2015-06-18Bluetooth: mgmt: program multi-adv on power onFlorian Grandel
Advertising instances programmed while powered off should be advertised once the device is powered. This patch ensures that all combinations of setting and/or adding advertising configuration while powered off will be correctly activated on power on.

2015-06-18Bluetooth: mgmt: multi adv for remove_advertising*()Florian Grandel
The remove_advertising() and remove_advertising_complete() functions had instance identifiers hard coded. Notably, when passing in 0x00 as an instance identifier to signal that all instances should be removed then the mgmt API would return a hard coded 0x01 rather than returning the expected value 0x00. This bug is being fixed by always referencing the instance identifier from the management API call instead. remove_advertising() is refactored to use the new dynamic advertising instance list. The logic is being changed to make multi-instance advertising actually work, notably the schedule_adv_instance() method is being referenced to make sure that other instances will continue to advertise even if one instance is being removed. The code is made more readable by factoring advertising instance management and initialization into the low-level hci_remove_adv_instance() and hci_adv_instances_clear() functions. The method now references the clear_adv_instance() helper method to remove duplicate logic and code.

2015-06-18Bluetooth: mgmt/hci_core: multi-adv for add_advertising*()Florian Grandel
The add_advertising() and add_advertising_complete() functions reference the now obsolete hdev->adv_instance struct. Both methods are being refactored to access the dynamic advertising instance list instead. This patch also introduces all logic necessary to actually deal with multiple instance advertising. Notably the mgmt_adv_inst_expired() and schedule_adv_inst() method are being referenced to schedule instances in a round robin fashion. This patch also introduces a "pending" flag into the adv_info struct. This is necessary to identify and remove recently added advertising instances when the HCI commands return with an error status code. Otherwise new advertising instances could be leaked without properly informing userspace about their existence.

2015-06-18Bluetooth: mgmt: multi adv for clear_adv_instances()Florian Grandel
The clear_adv_instance() function could not clean up multiple advertising instances previously. It is being changed to provide both, a means to clean up a single instance and cleaning up all instances at once. An additional instance parameter is being introduced to achieve this. Passing in 0x00 to this parameter signifies that all instances should be cleaned up. This semantics has been chosen similarly to the semantics of the instance parameter in the remove_advertising() function. When removing a single instance the method also ensures that another instance will be scheduled if available. When the currently advertising method is being removed, it will be canceled immediately.

2015-06-18Bluetooth: mgmt: multi adv for set_advertising*()Florian Grandel
The set_advertising() and set_advertising_complete() methods rely on the now obsolete hci_dev->adv_instance structure. We replace this reference by an equivalent access to the newly introduced dynamic advertising instance list. This patch introduces a helper function that schedules an advertising instance correctly calculating advertising timing based on the timeout and duration settings of the instance. Scheduling is factored into its own function for readability and code sharing. Signed-off-by: Florian Grandel <fgrandel@gmail.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
2015-06-18Bluetooth: mgmt: multi adv for create_instance_adv_data()Florian Grandel

2015-06-18Bluetooth: mgmt: multi adv for enable_advertising()Florian Grandel
Previously enable_advertising() would rely on get_adv_instance_scan_rsp_len() which checked for a hard coded instance identifier.

2015-06-18Bluetooth: hci_core/mgmt: move adv timeout to hdevFlorian Grandel
Currently the delayed work managing advertising duration and timeout is part of the advertising instance structure. This is not correct as only a single instance can be advertised at any given time. To implement round robin advertising a single delayed work structure is needed. To fix this the delayed work structure is being moved to the hci_dev structure. The instance specific variable is renamed to "remaining_time" to make it clear that this is the remaining lifetime of the instance and not the current advertising timeout.

2015-06-18Bluetooth: hci_core/mgmt: Introduce multi-adv listFlorian Grandel
The current hci dev structure only supports a single advertising instance. To support multi-instance advertising it is necessary to introduce a linked list of advertising instances so that multiple advertising instances can be dynamically added and/or removed. In a first step, the existing adv_instance member of the hci_dev struct is supplemented by a linked list of advertising instances. This patch introduces the list and supporting list management infrastructure. The list is not being used yet.
