Send an ACK frame with the current txack value in response to
every received reliable frame unless a TX reliable frame is being
sent. This modification allows re-transmitted frames from the remote
peer to be acknowledged rather than ignored. It means that the remote
peer knows which frame number to start re-transmitting from.
Without this modification, the recovery time to a missing frame
from the remote peer was unnecessarily being extended because the
headers of the out of order reliable frames were being discarded rather
than being processed. The frame headers of received frames will
indicate whether the local peer's transmissions have been
acknowledged by the remote peer. Therefore, the local peer may
unnecessarily re-transmit despite the remote peer already indicating
that the frame had been acknowledged in out of order reliable frame.

drivers/bluetooth/hci_bcsp.c contains some style issues as
highlighted by
./scripts/checkpatch.pl --strict -f drivers/bluetooth/hci_bcsp.c
a) comments - maintainer prefers network style comments
b) positioning of lines in multi-line statements
c) spaces after casts
d) missing blank lines after declarations
Therefore, tidy-up the above to make it easier to apply
future code changes that have conforming style.

This patch introduces support for Marvell Bluetooth controller over
UART (8897 for now). In order to send the final firmware at full speed,
a helper firmware is firstly sent. Firmware download is driven by the
controller which sends request firmware packets (including expected
size).
This driver is a global rework of the one proposed by
Amitkumar Karwar <akarwar@marvell.com>.

The RTL8822BE is a new Realtek wifi and BT device. Support for the BT
part is hereby added.
As this device is similar to most of the other Realtek BT devices, the
changes are minimal. The main difference is that the 8822BE needs a
configuration file for enabling and disabling features. Thus code is
added to select and load this configuration file. Although not needed
at the moment, hooks are added for the other devices that might need
such configuration files.
One additional change is to the routine that tests that the project
ID contained in the firmware matches the hardware. As the project IDs
are not sequential, continuing to use the position in the array as the
expected value of the ID would require adding extra unused entries in
the table, and any subsequant rearrangment of the array would break the
code. To fix these problems, the array elements now contain both the
hardware ID and the expected value for the project ID.

The workqueue "workqueue" queues multiple work items viz &qca->ws_awake_rx
&qca->ws_rx_vote_off, &qca->ws_awake_device, &qca->ws_tx_vote_off which
require strict execution ordering. Hence, an ordered dedicated workqueue
has been used to replace the deprecated create_singlethread_workqueue
instance.

On mips and parisc:

drv->st_register_cb_status = -EINPROGRESS;
There are actually two issues:
1. Whether "char" is signed or unsigned depends on the architecture.
As the completion callback data is used to pass a (negative) error
code, it should always be signed.
2. EINPROGRESS is 150 on mips, 245 on parisc.
Hence -EINPROGRESS doesn't fit in a signed 8-bit number.
Change the callback status from "char" to "int" to fix these.

The HCI_BREDR naming is confusing since it actually stands for Primary
Bluetooth Controller. Which is a term that has been used in the latest
standard. However from a legacy point of view there only really have
been Basic Rate (BR) and Enhanced Data Rate (EDR). Recent versions of
Bluetooth introduced Low Energy (LE) and made this terminology a little
bit confused since Dual Mode Controllers include BR/EDR and LE. To
simplify this the name HCI_PRIMARY stands for the Primary Controller
which can be a single mode or dual mode controller.

The cause of this is that btmrvl_sdio_host_to_card can access memory region
out of its allocated space due to:
1. the requested block size is smaller than SDIO_BLOCK_SIZE, and/or
2. the allocated memory is not BTSDIO_DMA_ALIGN-aligned.
This patch fixes the issue by allocating a buffer which is big enough for
SDIO_BLOCK_SIZE transfer and/or BTSDIO_DMA_ALIGN address relocation.

The format of Intel Bluetooth firmware filename for bootloader product
is ibt-<hw_variant>-<device_revision_id>.sfi
Currently the driver uses a constant value 11 (0x0b) for hw_variant
to support LnP/SfP product. But new product like WsP product has
a different value such as 12 (0x0c).
To support the multiple products, this patch replaces the constant
value of hw_variant to the actual hw_variant value read from
the device.

gpiod_get_optional can return either ERR_PTR or NULL pointer.
NULL case is not tested and then dereferenced later in desc_to_gpio.
Fix this by using non optional version which returns ERR_PTR in any
error case (this is not an optional gpio).
Use the same non optional version for the host-wake gpio.

hci_vhci driver creates a hci device object dynamically upon each
HCI_VENDOR_PKT write. Although it checks the already created object
and returns an error, it's still racy and may build multiple hci_dev
objects concurrently when parallel writes are performed, as the device
tracks only a single hci_dev object.
This patch introduces a mutex to protect against the concurrent device
creations.

The write handler allocates skbs and queues them into data->readq.
Read side should read them, if there is any. If there is none, skbs
should be dropped by hdev->flush. But this happens only if the device
is HCI_UP, i.e. hdev->power_on work was triggered already. When it was
not, skbs stay allocated in the queue when /dev/vhci is closed. So
purge the queue in ->release.
Program to reproduce:
#include <err.h>
#include <fcntl.h>
#include <stdio.h>
#include <unistd.h>
#include <sys/stat.h>
#include <sys/types.h>
#include <sys/uio.h>
int main()
{
char buf[] = { 0xff, 0 };
struct iovec iov = {
.iov_base = buf,
.iov_len = sizeof(buf),
};
int fd;
while (1) {
fd = open("/dev/vhci", O_RDWR);
if (fd < 0)
err(1, "open");
usleep(50);
if (writev(fd, &iov, 1) < 0)
err(1, "writev");
usleep(50);
close(fd);
}
return 0;

Both vhci_get_user and vhci_release race with open_timeout work. They
both contain cancel_delayed_work_sync, but do not test whether the
work actually created hdev or not. Since the work can be in progress
and _sync will wait for finishing it, we can have data->hdev allocated
when cancel_delayed_work_sync returns. But the call sites do 'if
(data->hdev)' *before* cancel_delayed_work_sync.
As a result:
* vhci_get_user allocates a second hdev and puts it into
data->hdev. The former is leaked.
* vhci_release does not release data->hdev properly as it thinks there
is none.
Fix both cases by moving the actual test *after* the call to
cancel_delayed_work_sync.
This can be hit by this program:
#include <err.h>
#include <fcntl.h>
#include <stdio.h>
#include <stdlib.h>
#include <time.h>
#include <unistd.h>
#include <sys/stat.h>
#include <sys/types.h>
int main(int argc, char **argv)
{
int fd;
srand(time(NULL));
while (1) {
const int delta = (rand() % 200 - 100) * 100;
fd = open("/dev/vhci", O_RDWR);
if (fd < 0)
err(1, "open");
usleep(1000000 + delta);
close(fd);
}
return 0;
}
And the result is:

This driver implements support for iBT2.1 Bluetooth controller embedded
in the AG620 communication combo. The controller needs to be configured
with bddata and can be patched with a binary patch file (pbn).
These operations are performed in manufacturing mode.
