Bluetooth: Replace zero-length array with flexible-array member 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 inadvertently 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. [1] https://gcc.gnu.org/onlinedocs/gcc/Zero-Length.html [2] https://github.com/KSPP/linux/issues/21 [3] commit 76497732932f ("cxgb3/l2t: Fix undefined behaviour") Signed-off-by: Gustavo A. R.

Bluetooth: Add support for controller specific logging To enable controller specific logging, the userspace daemon has to have the ability to log per controller. To facilitate this support, provide a dedicated logging channel. Messages in this channel will be included in the monitor queue and with that also forwarded to monitoring tools along with the actual hardware traces. All messages from the logging channel are timestamped and with that allow an easy correlation between userspace messages and hardware events. This will increase the ability to debug problems faster.

Bluetooth: Move HCI socket definitions into its own header file All the HCI sockets and ioctl based definitions have been in a global header file that also includes all the HCI protocol structures. To make this a bit cleaner, move them into its own file. This also adjusts fs/compat_ioctl.c to only include this new file and not all the protocol structures that are not needed.
