Bluetooth: ISO: Add support for periodic adv reports processing

2025-12-06T21:12:12Z

[ Upstream commit 9c0826310bfb784c9bac7d1d9454e304185446c5 ] In the case of a Periodic Synchronized Receiver, the PA report received from a Broadcaster contains the BASE, which has information about codec and other parameters of a BIG. This isnformation is stored and the application can retrieve it using getsockopt(BT_ISO_BASE).

Bluetooth: HCI: Fix tracking of advertisement set/instance 0x00

2025-12-06T21:12:12Z

[ Upstream commit 0d92808024b4e9868cef68d16f121d509843e80e ] This fixes the state tracking of advertisement set/instance 0x00 which is considered a legacy instance and is not tracked individually by adv_instances list, previously it was assumed that hci_dev itself would track it via HCI_LE_ADV but that is a global state not specifc to instance 0x00, so to fix it a new flag is introduced that only tracks the state of instance 0x00.

Bluetooth: add quirk for broken address properties

2024-04-10T14:28:24Z

commit 39646f29b100566451d37abc4cc8cdd583756dfe upstream. Some Bluetooth controllers lack persistent storage for the device address and instead one can be provided by the boot firmware using the 'local-bd-address' devicetree property. The Bluetooth devicetree bindings clearly states that the address should be specified in little-endian order, but due to a long-standing bug in the Qualcomm driver which reversed the address some boot firmware has been providing the address in big-endian order instead. Add a new quirk that can be set on platforms with broken firmware and use it to reverse the address when parsing the property so that the underlying driver bug can be fixed.

Bluetooth: Remove HCI_POWER_OFF_TIMEOUT

Bluetooth: fix debugfs registration

2023-06-14T09:15:28Z

commit fe2ccc6c29d53e14d3c8b3ddf8ad965a92e074ee upstream. Since commit ec6cef9cd98d ("Bluetooth: Fix SMP channel registration for unconfigured controllers") the debugfs interface for unconfigured controllers will be created when the controller is configured. There is however currently nothing preventing a controller from being configured multiple time (e.g. setting the device address using btmgmt) which results in failed attempts to register the already registered debugfs entries: debugfs: File 'features' in directory 'hci0' already present! debugfs: File 'manufacturer' in directory 'hci0' already present! debugfs: File 'hci_version' in directory 'hci0' already present! ... debugfs: File 'quirk_simultaneous_discovery' in directory 'hci0' already present! Add a controller flag to avoid trying to register the debugfs interface more than once.

Bluetooth: Add new quirk for broken set random RPA timeout for ATS2851

Bluetooth: Add new quirk for broken local ext features page 2

2023-05-24T16:32:39Z

[ Upstream commit 8194f1ef5a815aea815a91daf2c721eab2674f1f ] Some adapters (e.g. RTL8723CS) advertise that they have more than 2 pages for local ext features, but they don't support any features declared in these pages. RTL8723CS reports max_page = 2 and declares support for sync train and secure connection, but it responds with either garbage or with error in status on corresponding commands.
