Bluetooth: btsdio: Do not bind to non-removable CYW4373

2024-09-12T16:24:08+00:00

CYW4373 devices soldered onto the PCB (non-removable), use a UART connection for Bluetooth and the advertised btsdio support as an SDIO function should be ignored. Signed-off-by: Scott Ehlert Signed-off-by: Tim Harvey Signed-off-by: Luiz Augusto von Dentz

Bluetooth: HCI: Remove HCI_AMP support

2024-05-14T14:54:49+00:00

Since BT_HS has been remove HCI_AMP controllers no longer has any use so remove it along with the capability of creating AMP controllers. Since we no longer need to differentiate between AMP and Primary controllers, as only HCI_PRIMARY is left, this also remove hdev->dev_type altogether.

Revert "Bluetooth: btsdio: fix use after free bug in btsdio_remove due to unfinished work"

This reverts commit 1e9ac114c4428fdb7ff4635b45d4f46017e8916f. This patch introduces a possible null-ptr-def problem. Revert it. And the fixed bug by this patch have resolved by commit 73f7b171b7c0 ("Bluetooth: btsdio: fix use after free bug in btsdio_remove due to race condition").

Bluetooth: btsdio: fix use after free bug in btsdio_remove due to race condition

2023-04-10T17:23:01+00:00

In btsdio_probe, the data->work is bound with btsdio_work. It will be started in btsdio_send_frame. If the btsdio_remove runs with a unfinished work, there may be a race condition that hdev is freed but used in btsdio_work. Fix it by canceling the work before do cleanup in btsdio_remove.

Bluetooth: btsdio: fix use after free bug in btsdio_remove due to unfinished work

2023-03-23T20:09:38+00:00

In btsdio_probe, &data->work was bound with btsdio_work.In btsdio_send_frame, it was started by schedule_work. If we call btsdio_remove with an unfinished job, there may be a race condition and cause UAF bug on hdev.
