Bluetooth: hci_dev: replace 'quirks' integer by 'quirk_flags' bitmap

2025-07-24T06:58:37+00:00

[ Upstream commit 6851a0c228fc040dce8e4c393004209e7372e0a3 ] The 'quirks' member already ran out of bits on some platforms some time ago. Replace the integer member by a bitmap in order to have enough bits in future. Replace raw bit operations by accessor macros.

Bluetooth: btintel: Check if controller is ISO capable on btintel_classify_pkt_type

2025-07-24T06:58:28+00:00

commit 6ec3185fbc3528f2284c347fb9bd8be6fa672ed4 upstream. Due to what seem to be a bug with variant version returned by some firmwares the code may set hdev->classify_pkt_type with btintel_classify_pkt_type when in fact the controller doesn't even support ISO channels feature but may use the handle range expected from a controllers that does causing the packets to be reclassified as ISO causing several bugs. To fix the above btintel_classify_pkt_type will attempt to check if the controller really supports ISO channels and in case it doesn't don't reclassify even if the handle range is considered to be ISO, this is considered safer than trying to fix the specific controller/firmware version as that could change over time and causing similar problems in the future.

Bluetooth: btintel: Check dsbr size from EFI variable

2025-06-19T13:39:59+00:00

[ Upstream commit 3aa1dc3c9060e335e82e9c182bf3d1db29220b1b ] Since the size of struct btintel_dsbr is already known, we can just start there instead of querying the EFI variable size. If the final result doesn't match what we expect also fail. This fixes a stack buffer overflow when the EFI variable is larger than struct btintel_dsbr.

Bluetooth: btintel: Add support to configure TX power

2025-03-25T16:51:42+00:00

BRDS - Bluetooth Regulatory Domain Specific absorption rate Bluetooth has regulatory limitations which prohibit or allow usage of certain bands or channels as well as limiting Tx power. The Tx power values can be configured in ACPI table. This patch reads from ACPI entry configures the controller accordingly.

Bluetooth: Use str_enable_disable-like helpers

2025-01-15T15:36:11+00:00

Replace ternary (condition ? "enable" : "disable") syntax with helpers from string_choices.h because: 1. Simple function call with one argument is easier to read. Ternary operator has three arguments and with wrapping might lead to quite long code. 2. Is slightly shorter thus also easier to read. 3. It brings uniformity in the text - same string. 4. Allows deduping by the linker, which results in a smaller binary file. Signed-off-by: Krzysztof Kozlowski Signed-off-by: Luiz Augusto von Dentz
