Bluetooth: btintel: Replace zero-length array with flexible-array member

2020-02-13T07:28:38+00:00

The current codebase makes use of the zero-length array language extension to the C90 standard, but the preferred mechanism to declare variable-length types such as these ones is a flexible array member[1][2], introduced in C99: struct foo { int stuff; struct boo array[]; }; By making use of the mechanism above, we will get a compiler warning in case the flexible array does not occur last in the structure, which will help us prevent some kind of undefined behavior bugs from being inadvertenly introduced[3] to the codebase from now on. Also, notice that, dynamic memory allocations won't be affected by this change: "Flexible array members have incomplete type, and so the sizeof operator may not be applied. As a quirk of the original implementation of zero-length arrays, sizeof evaluates to zero."[1] This issue was found with the help of Coccinelle.

Bluetooth: btusb: Trigger Intel FW download error recovery

2019-10-17T07:23:47+00:00

Sometimes during FW data download stage, in case of an error is encountered the controller device could not be recovered. To recover from such failures send Intel hard Reset to re-trigger FW download in following error scenarios: 1. Intel Read version command error 2. Firmware download timeout 3. Failure in Intel Soft Reset for switching to operational FW 4. Boot timeout for switching to operaional FW Signed-off-by: Raghuram Hegde Signed-off-by: Chethan T N Signed-off-by: Amit K Bag Signed-off-by: Marcel Holtmann

Bluetooth: btintel: make array 'param' static, shrinks object size

2018-01-08T20:44:22+00:00

Don't populate the const read-only array 'param' on the stack but instead make it static.

Bluetooth: Use bt_dev_err and bt_dev_info when possible

2017-10-30T10:25:45+00:00

In case of using BT_ERR and BT_INFO, convert to bt_dev_err and bt_dev_info when possible. This allows for controller specific reporting. Signed-off-by: Marcel Holtmann Signed-off-by: Johan Hedberg
