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.

This patch will fix the below issues
1. Discarding memory dump events if memdump state is moved to
MEMDUMP_TIMEOUT.
2. Fixed race conditions between qca_hw_error() and qca_controller_memdump
while free memory dump buffers using mutex lock
3. Moved timeout timer to delayed work queue
4. Injecting HW error event in a case when dumps failed to receive and HW
error event is not yet received.
5. Clearing hw error and command timeout function callbacks before
sending pre shutdown command.
Collecting memory dump will follow any of the below sequence.
Sequence 1:
Receiving Memory dump events from the controller
Received entire dump in stipulated time
Received HW error event from the controller
Controller Reset from HOST
Sequence 2:
Receiving Memory dump events from the controller
Failed to Receive entire dump in stipulated time
A Timeout schedules and if no HW error event received a fake HW
error event will be injected.
Controller Reset from HOST.
Sequence 3:
Received HW error event
HOST trigger SSR by sending crash packet to controller.
Received entire dump in stipulated time
Controller Reset from HOST

Currently, kmemdup is applied to the firmware data, and it invokes
kmalloc under the hood. The firmware size and patch_length are big (more
than PAGE_SIZE), and on some low-end systems (like ASUS E202SA) kmalloc
may fail to allocate a contiguous chunk under high memory usage and
fragmentation:
Bluetooth: hci0: RTL: examining hci_ver=06 hci_rev=000a lmp_ver=06 lmp_subver=8821
Bluetooth: hci0: RTL: rom_version status=0 version=1
Bluetooth: hci0: RTL: loading rtl_bt/rtl8821a_fw.bin
kworker/u9:2: page allocation failure: order:4, mode:0x40cc0(GFP_KERNEL|__GFP_COMP), nodemask=(null),cpuset=/,mems_allowed=0
<stack trace follows>
As firmware load happens on each resume, Bluetooth will stop working
after several iterations, when the kernel fails to allocate an order-4
page.
This patch replaces kmemdup with kvmalloc+memcpy. It's not required to
have a contiguous chunk here, because it's not mapped to the device
directly.

This patch registers hdev->shutdown() callback and also sets

during hci down and power-on/initialize the chip again during hci up. As
wcn399x already enabled this, this patch also removed the callback register
and QUIRK setting in qca_setup() for wcn399x and uniformly do this in the

This patch adds the retry of btsoc initialization when it fails. There are
reports that the btsoc initialization may fail on some platforms but the
repro ratio is very low. The symptoms is the firmware downloading failed
due to the UART write timed out. The failure may be caused by UART,
platform HW or the btsoc itself but it's very difficlut to root cause,
given the repro ratio is very low. Add a retry for the btsoc initialization
can work around most of the failures and make Bluetooth finally works.

We will collect the ramdump of BT controller when hardware error event
received before rebooting the HCI layer. Before restarting a subsystem
or a process running on a subsystem, it is often required to request
either a subsystem or a process to perform proper cache dump and
software failure reason into a memory buffer which application
processor can retrieve afterwards. SW developers can often provide
initial investigation by looking into that debugging information.

Add BCM vendor specific command to configure PCM parameters. The new
vendor opcode allows us to set the sco routing, the pcm interface rate,
and a few other pcm specific options (frame sync, sync mode, and clock
mode). See broadcom-bluetooth.txt in Documentation for more information
about valid values for those settings.
Here is an example trace where this opcode was used to configure
a BCM4354:
< HCI Command: Vendor (0x3f|0x001c) plen 5
01 02 00 01 01
> HCI Event: Command Complete (0x0e) plen 4
Vendor (0x3f|0x001c) ncmd 1
Status: Success (0x00)
We can read back the values as well with ocf 0x001d to confirm the
values that were set:
$ hcitool cmd 0x3f 0x001d
< HCI Command: ogf 0x3f, ocf 0x001d, plen 0
> HCI Event: 0x0e plen 9

Without updating the patchram, the BCM4354 does not support a higher
operating speed. The normal bcm_setup follows the correct order
(init_speed, patchram and then oper_speed) but the serdev driver will
set the operating speed before calling the hu->setup function. Thus,
for the BCM4354, don't set the operating speed before patchram.

Add the device ID for the WiFi/BT/FM combo chip BCM4334 (rev B0).
The chip seems to use 43:34:b0:00:00:00 as default address,
so add it to the list of default addresses and leave it up
to the user to configure a valid one.

If setup() fails a reference for runtime PM has already
been taken. Proper use of the error handling in btusb_open()is needed.
You cannot just return.

Variables which are named with rome are commonly used for all the
BT SoC's. Instead of continuing further, renamed them to generic
name.

This adds the missing MODULE_DEVICE_TABLE() for SDIO IDs. While certain
platforms using this driver indeed have HW issues causing problems if
the module is loaded too early - this should be handled from user-space
by blacklisting it or delaying the loading.

Syzbot reported an invalid-free that I introduced fixing a memleak.
bcsp_recv() also frees bcsp->rx_skb but never nullifies its value.
Nullify bcsp->rx_skb every time it is freed.

Add PM suspend/resume callbacks for hci_qca driver.
BT host will make sure both Rx and Tx go into sleep state in
qca_suspend. Without this, Tx may still remain in awake state, which
prevents BTSOC from entering deep sleep. For example, BlueZ will send
Set Event Mask to device when suspending and this will wake the device
Rx up. However, the Tx idle timeout on the host side is 2000 ms. If the
host is suspended before its Tx idle times out, it won't send
HCI_IBS_SLEEP_IND to the device and the device Rx will remain awake.
We implement this by canceling relevant work in workqueue, sending
HCI_IBS_SLEEP_IND to the device and then waiting HCI_IBS_SLEEP_IND sent
by the device.
In order to prevent the device from being awaken again after qca_suspend
is called, we introduce QCA_SUSPEND flag. QCA_SUSPEND is set in the
beginning of qca_suspend to indicate system is suspending and that we'd
like to ignore any further wake events.
With QCA_SUSPEND and spinlock, we can avoid race condition, e.g. if
qca_enqueue acquires qca->hci_ibs_lock before qca_suspend calls
cancel_work_sync and then qca_enqueue adds a new qca->ws_awake_device
work after the previous one is cancelled.
If BTSOC wants to wake the whole system up after qca_suspend is called,
it will keep sending HCI_IBS_WAKE_IND and uart driver will take care of
waking the system. For example, uart driver will reconfigure its Rx pin
to a normal GPIO pin and enable irq wake on that pin when suspending.
Once host detects Rx falling, the system will begin resuming. Then, the
BT host clears QCA_SUSPEND flag in qca_resume and begins dealing with
normal HCI packets. By doing so, only a few HCI_IBS_WAKE_IND packets are
lost and there is no data packet loss.
