This issue starts from linux-5.10-rc1, I reproduced this issue on my
Dell Inspiron 7447 with BT adapter 0cf3:e005, the kernel will print
out: "Bluetooth: hci0: don't support firmware rome 0x31010000", and
someone else also reported the similar issue to bugzilla #211571.
I found this is a regression introduced by 'commit b40f58b973
("Bluetooth: btusb: Add Qualcomm Bluetooth SoC WCN6855 support"), the
patch assumed that if high ROM version is not zero, it is an adapter
on WCN6855, but many old adapters don't need to load rampatch or nvm,
and they have non-zero high ROM version.
To fix it, let the driver match the rom_version in the
qca_devices_table first, if there is no entry matched, check the
high ROM version, if it is not zero, we assume this adapter is ready
to work and no need to load rampatch and nvm like previously.

Enlarging the size of 'struct btmtk_hci_wmt_cmd' makes it no longer
fit on the kernel stack, as seen from this compiler warning:
drivers/bluetooth/btusb.c:3365:12: error: stack frame size of 1036 bytes in function 'btusb_mtk_hci_wmt_sync' [-Werror,-Wframe-larger-than=]
Change the function to dynamically allocate the buffer instead.
As there are other sleeping functions called from the same location,
using GFP_KERNEL should be fine here, and the runtime overhead should
not matter as this is rarely called.
Unfortunately, I could not figure out why the message size is
increased in the previous patch. Using dynamic allocation means
any size is possible now, but there is still a range check that
limits the total size (including the five-byte header) to 255
bytes, so whatever was intended there is now undone.

I tried to disable the autosuspend on btusb through the module
parameter enable_autosuspend, this parameter is set to N, but the usb
bluetooth device is still runtime suspended.
$ cat /sys/module/btusb/parameters/enable_autosuspend
N
$ cat /sys/bus/usb/devices/3-10/power/runtime_status
suspended
$ cat /sys/bus/usb/devices/3-10/power/runtime_suspended_time
65187
We already set ".supports_autosuspend = 1" in the usb_driver, this
device will be set autosuspend enabled by usb core, we don't need
to call usb_enable_autosuspend() in the btusb_probe(). Instead if
users set the parameter enable_autosuspend to N, we need to call
usb_disable_autosuspend() in the btusb_probe(). After this change
and set the parameter to N, we could see the device is not runtime
suspended anymore.
$ cat /sys/module/btusb/parameters/enable_autosuspend
N
$ cat /sys/bus/usb/devices/3-10/power/runtime_status
active
$ cat /sys/bus/usb/devices/3-10/power/runtime_suspended_time
0
And if we disable the autosuspend in the btusb_probe(), we need to
enable the autosuspend in the disconnect(), this could guarantee
that the device could be runtime suspended after we rmmod the btusb.

When alt mode 6 is not available, fallback to the kernel <= 5.7 behavior
of always using alt mode 1.
Prior to kernel 5.8, btusb would always use alt mode 1 for WBS (Wide
Band Speech aka mSBC aka transparent SCO). In commit baac6276c0
("Bluetooth: btusb: handle mSBC audio over USB Endpoints") this
was changed to use alt mode 6, which is the recommended mode in the
Bluetooth spec (Specifications of the Bluetooth System, v5.0, Vol 4.B
§2.2.1). However, many if not most BT USB adapters do not support alt
mode 6. In fact, I have been unable to find any which do.
In kernel 5.8, this was changed to use alt mode 6, and if not available,
use alt mode 0. But mode 0 has a zero byte max packet length and can
not possibly work. It is just there as a zero-bandwidth dummy mode to
work around a USB flaw that would prevent device enumeration if
insufficient bandwidth were available for the lowest isoc mode
supported.
In effect, WBS was broken for all USB-BT adapters that do not support
alt 6, which appears to nearly all of them.
Then in commit 461f95f04f ("Bluetooth: btusb: USB alternate setting 1 for
WBS") the 5.7 behavior was restored, but only for Realtek adapters.
I've tested a Broadcom BRCM20702A and CSR 8510 adapter, both work with
the 5.7 behavior and do not with the 5.8.
So get rid of the Realtek specific flag and use the 5.7 behavior for all
adapters as a fallback when alt 6 is not available. This was the
kernel's behavior prior to 5.8 and I can find no adapters for which it
is not correct. And even if there is an adapter for which this does not
work, the current behavior would be to fall back to alt 0, which can not
possibly work either, and so is no better.

With the recent btusb change to detect and deal with more fake CSR
controllers, I decided to see if fake CSR controllers with Barrot
8041a02 chips would now work.
After much experimentation I came to the conclusion that it works, if I
have autosuspend enabled initially and then disable it after the device
has suspended at least once. Yes this is very weird, but I've tried many
things, like manually clearing the remote-wakeup feature. Doing a
runtime-resume + runtime suspend is the only way to get the receiver
to actually report received data (and/or pairing info) through its
bulk rx endpoint.
But the funkyness of the bulk-endpoint does not stop there, I mainly
found out about this problem, because with autosuspend enabled
(which usually ensures the suspend at least once condition is met),
the receiver stops reporting received data through its bulk rx endpoint
as soon as autosuspend kicks in. So I initially just disabled
autosuspend, but then the receiver does not work at all.
This was with a fake CSR receiver with a Barrot 8041a02 chip with a
bcdDevice value of 0x8891, a lmp_subver of 0x1012, a hci_rev of 0x0810
and a hci_ver of BLUETOOTH_VER_4_0.
Summarizing this specific fake CSR receiver has the following 2 issues:
1. The bulk rx endpoint will never report any data unless
the device was suspended at least once.
2. They will not wakeup when autosuspended and receiving data on their
bulk rx endpoint from e.g. a keyboard or mouse (IOW remote-wakeup support
is broken for the bulk endpoint).
Add a workaround for 1. which enables runtime-suspend, force-suspends
the hci and then wakes-it up by disabling runtime-suspend again.
Add a workaround for 2. which clears the hci's can_wake flag, this way
the hci will still be autosuspended when it is not open.

For some reason they tend to squat on the very first CSR/
Cambridge Silicon Radio VID/PID instead of paying fees.
This is an extremely common problem; the issue goes as back as 2013
and these devices are only getting more popular, even rebranded by
reputable vendors and sold by retailers everywhere.
So, at this point in time there are hundreds of modern dongles reusing
the ID of what originally was an early Bluetooth 1.1 controller.
Linux is the only place where they don't work due to spotty checks
in our detection code. It only covered a minimum subset.
So what's the big idea? Take advantage of the fact that all CSR
chips report the same internal version as both the LMP sub-version and
HCI revision number. It always matches, couple that with the manufacturer
code, that rarely lies, and we now have a good idea of who is who.
Additionally, by compiling a list of user-reported HCI/lsusb dumps, and
searching around for legit CSR dongles in similar product ranges we can
find what CSR BlueCore firmware supported which Bluetooth versions.
That way we can narrow down ranges of fakes for each of them.
e.g. Real CSR dongles with LMP subversion 0x73 are old enough that
support BT 1.1 only; so it's a dead giveaway when some
third-party BT 4.0 dongle reuses it.
So, to sum things up; there are multiple classes of fake controllers
reusing the same 0A12:0001 VID/PID. This has been broken for a while.
Known 'fake' bcdDevices: 0x0100, 0x0134, 0x1915, 0x2520, 0x7558, 0x8891

In commit f44cb4b19e ("Bluetooth: btusb: Fix quirk for Atheros
1525/QCA6174") we tried to address the non-working Atheros BT devices
by changing the quirk from BTUSB_ATH3012 to BTUSB_QCA_ROME. This made
such devices working while it turned out to break other existing chips
with the very same USB ID, hence it was reverted afterwards.
This is another attempt to tackle the issue. The essential point to
use BTUSB_QCA_ROME is to apply the btusb_setup_qca() and do RAM-
patching. And the previous attempt failed because btusb_setup_qca()
returns -ENODEV if the ROM version doesn't match with the expected
ones. For some devices that have already the "correct" ROM versions,
we may just skip the setup procedure and continue the rest.
So, the first fix we'll need is to add a check of the ROM version in
the function to skip the setup if the ROM version looks already sane,
so that it can be applied for all ath devices.
However, the world is a bit more complex than that simple solution.
Since BTUSB_ATH3012 quirk checks the bcdDevice and bails out when it's
0x0001 at the beginning of probing, so the device probe always aborts
here.
In this patch, we add another check of ROM version again, and if the
device needs patching, the probe continues. For that, a slight
refactoring of btusb_qca_send_vendor_req() was required so that the
probe function can pass usb_device pointer directly before allocating
hci_dev stuff.

Jeremy Cline correctly points out in rhbz#1514836 that a device where the
QCA rome chipset needs the USB_QUIRK_RESET_RESUME quirk, may also ship
with a different wifi/bt chipset in some configurations.
If that is the case then we are needlessly penalizing those other chipsets
with a reset-resume quirk, typically causing 0.4W extra power use because
this disables runtime-pm.
This commit moves the DMI table check to a btusb_check_needs_reset_resume()
helper (so that we can easily also call it for other chipsets) and calls
this new helper only for QCA_ROME chipsets for now.

Fun set of conflict resolutions here...
For the mac80211 stuff, these were fortunately just parallel
adds. Trivially resolved.
In drivers/net/phy/phy.c we had a bug fix in 'net' that moved the
function phy_disable_interrupts() earlier in the file, whilst in
'net-next' the phy_error() call from this function was removed.
In net/ipv4/xfrm4_policy.c, David Ahern's changes to remove the
'rt_table_id' member of rtable collided with a bug fix in 'net' that
added a new struct member "rt_mtu_locked" which needs to be copied
over here.
The mlxsw driver conflict consisted of net-next separating
the span code and definitions into separate files, whilst
a 'net' bug fix made some changes to that moved code.
The mlx5 infiniband conflict resolution was quite non-trivial,
the RDMA tree's merge commit was used as a guide here, and
here are their notes:
====================
Due to bug fixes found by the syzkaller bot and taken into the for-rc
branch after development for the 4.17 merge window had already started
being taken into the for-next branch, there were fairly non-trivial
merge issues that would need to be resolved between the for-rc branch
and the for-next branch. This merge resolves those conflicts and
provides a unified base upon which ongoing development for 4.17 can
be based.
Conflicts:
drivers/infiniband/hw/mlx5/main.c - Commit 42cea83f95
(IB/mlx5: Fix cleanup order on unload) added to for-rc and
commit b5ca15ad7e (IB/mlx5: Add proper representors support)
add as part of the devel cycle both needed to modify the
init/de-init functions used by mlx5. To support the new
representors, the new functions added by the cleanup patch
needed to be made non-static, and the init/de-init list
added by the representors patch needed to be modified to
match the init/de-init list changes made by the cleanup
patch.
Updates:
drivers/infiniband/hw/mlx5/mlx5_ib.h - Update function
prototypes added by representors patch to reflect new function
names as changed by cleanup patch
drivers/infiniband/hw/mlx5/ib_rep.c - Update init/de-init

Note that after this commit the btusb_needs_reset_resume_table is now

Commit 7d06d5895c ("Revert "Bluetooth: btusb: fix QCA...suspend/resume"")
removed the setting of the BTUSB_RESET_RESUME quirk for QCA Rome devices,
instead favoring adding USB_QUIRK_RESET_RESUME quirks in usb/core/quirks.c.
This was done because the DIY BTUSB_RESET_RESUME reset-resume handling
has several issues (see the original commit message). An added advantage
of moving over to the USB-core reset-resume handling is that it also
disables autosuspend for these devices, which is similarly broken on these.
But there are 2 issues with this approach:
1) It leaves the broken DIY BTUSB_RESET_RESUME code in place for Realtek
devices.
2) Sofar only 2 of the 10 QCA devices known to the btusb code have been
added to usb/core/quirks.c and if we fix the Realtek case the same way
we need to add an additional 14 entries. So in essence we need to
duplicate a large part of the usb_device_id table in btusb.c in
usb/core/quirks.c and manually keep them in sync.
This commit instead restores setting a reset-resume quirk for QCA devices
in the btusb.c code, avoiding the duplicate usb_device_id table problem.
This commit avoids the problems with the original DIY BTUSB_RESET_RESUME
code by simply setting the USB_QUIRK_RESET_RESUME quirk directly on the
usb_device.
This commit also moves the BTUSB_REALTEK case over to directly setting the
USB_QUIRK_RESET_RESUME on the usb_device and removes the now unused
BTUSB_RESET_RESUME code.

On many laptops the btusb device is the only USB device not having USB
autosuspend enabled, this causes not only the HCI but also the USB
controller to stay awake, together using aprox. 0.4W of power.
Modern ultrabooks idle around 6W (at 50% screen brightness), 3.5W for
Apollo Lake devices. 0.4W is a significant chunk of this (7 / 11%).
The btusb driver already contains code to allow enabling USB autosuspend,
but currently leaves it up to the user / userspace to enable it. This
means that for most people it will not be enabled, leading to an
unnecessarily high power consumption.
Since enabling it is not entirely without risk of regressions, this
commit adds a Kconfig option so that Linux distributions can choose to
enable it by default. This commit also adds a module option so that when
distros receive bugs they can easily ask the user to disable it again
for easy debugging.

Commit 9834e586fa ("Bluetooth: btusb: Add workaround for Broadcom devices
without product id") was added to deal with the BT part of the BCM4356A2
on GPD pocket laptops having an usb vid:pid of 0000:0000.
After another commit to add support for the BCM UART connected BT ACPI-id
BCM2E7E used on the GPD win, it turns out that the BT on the GPD pocket is
connected via both USB and UART. Adding support for the BCM2E7E ACPI-id
causes it to switch to UART mode.
The Windows shipped with the device is using it in UART mode and the
presence of the BCM2E7E ACPI-id combined with the all 0 USB vid:pid
indicates that the BT part was never meant to be used in USB mode.
With the recent patches to use serdev device enumeration / instantiation
for UART attached ACPI enumerated BT devices, everything work OOTB in UART
mode and the workaround for the all 0 USB vid:pid is no longer needed.
This reverts commit 9834e586fa ("Bluetooth: btusb: Add workaround for
Broadcom devices without product id").

BT-Controller connected as platform non-root-hub device and

Ref. usb_new_device().
At present wakeup-capability get enabled by hid-input device from usb
function driver(e.g. BT HID device) at runtime. Again some functional
driver does not set usb-wakeup capability(e.g LE HID device implement

Most of the device operation (such as mass storage) initiated from host
(except HID) and USB wakeup aligned with host resume procedure. For BT
device, usb-wakeup capability need to enable form btusc driver as a
generic solution for multiple profile use case and required for USB remote

Joe and Bjørn suggested that it'd be nicer to not have the

Add skb_put_u8() for this case, and use it across the code,
using the following spatch:

typedef u8;
identifier fn = {skb_put};
fresh identifier fn2 = fn ## "_u8";

- *(u8 *)fn(SKB, S) = C;

Note that due to the "S", the spatch isn't perfect, it should
have checked that S is 1, but there's also places that use a
sizeof expression like sizeof(var) or sizeof(u8) etc. Turns
out that nobody ever did something like
*(u8 *)skb_put(skb, 2) = c;
which would be wrong anyway since the second byte wouldn't be

been Basic Rate (BR) and Enhanced Data Rate (EDR). Recent versions of
Bluetooth introduced Low Energy (LE) and made this terminology a little

simplify this the name HCI_PRIMARY stands for the Primary Controller

SCO packet reassembler may have a fragment of SCO packet, from
previous connection, cached and not removed when SCO connection
is ended. Packets from new SCO connection are then going to be
attached to that fragment, creating an invalid SCO packets.
Controllers like Intel's WilkinsPeak are always fragmenting
SCO packet into 3 parts (#1, #2, #3). Packet #1 contains
SCO header and audio data, others just audio data. if there is
a fragment cached from previous connection, i.e. #1, first
SCO packet from new connection is going to be attached to it
creating packet consisting of fragments #1-#1-#2. This will
be forwarded to upper layers. After that, fragment #3 is going
to be used as a starting point for another SCO packet.
It does not contain a SCO header, but the code expects it,
casts a SCO header structure on it, and reads whatever audio
data happens to be there as SCO packet length and handle.
From that point on, we are assembling random data into SCO
packets. Usually it recovers quickly as initial audio data
contains mostly zeros (muted stream), but setups of over
4 seconds were observed.
Issue manifests itself by printing on the console:
Bluetooth: hci0 SCO packet for unknown connection handle 48
Bluetooth: hci0 SCO packet for unknown connection handle 2560
Bluetooth: hci0 SCO packet for unknown connection handle 12288
It may also show random handles if audio data was non-zeroed.
Hcidump shows SCO packets with random length and handles.
Few messages with handle 0 at connection creation are OK
for some controllers (like WilkinsPeak), as there are SCO packets
with zeroed handle at the beginning (possible controller bug).
Few of such messages at connection end, with a handle looking
sane (around 256, 512, 768 ...) is also OK, as these are last
SCO packets that were assembled and sent up, before connection
was ended, but were not handled in time.
This issue may still manifest itself on WilkinsPeak as it sometimes,
at SCO connection creation, does not send third fragment of first
SCO packet (#1-#2-#1-#2-#3...). This is a firmware bug and this
patch does not address it.

8E FC 03 11 22 33 02 FC 03 00 00 00
Previously, btusb sends two commands:
09 FC 06 8E FC 03 11 22 33
09 FC 06 02 FC 03 00 00 00
This won't work because the length of parameters are 6 which violates
the 4 byte alignment.
This patch will append them together and send as one command:
09 FC 0C 8E FC 03 11 22 33 02 FC 03 00 00 00

Realtek btusb devices don't currently work after suspend/resume because
the updated firmware is quietly lost - the USB hub doesn't notice any
status change upon resume, but some kind of reset has definitely
happened as the LMP subversion has reverted to its original value.
Set the reset_resume flag to trigger probe and upload the new firmware
again.
Like the vendor code, I assume this is not needed when the device is
selected as a wakeup source and hence will retain power during suspend.
On the 2 products I have to hand, when trying this configuration the
hardware seems unable to keep the device powered up during suspend.
The USB hub then detects a status change on resume and does a reset,
so we do not end up in broken state.

Remove test of command reply status as it is already performed by
__hci_cmd_sync().
__hci_cmd_sync_ev() function already returns an error if it got a
non-zero status either through a Command Complete or a Command
Status event.
For both of these events the status is collected up in the event
handlers called by hci_event_packet() and then passed as the second
parameter to req_complete_skb(). The req_complete_skb() callback in
turn is hci_req_sync_complete() for __hci_cmd_sync_ev() which stores
the status in hdev->req_result. The hdev->req_result is then further
converted through bt_to_errno() back in __hci_cmd_sync_ev().

Realtek ship a variety of bluetooth USB devices that identify
themselves with standard USB Bluetooth device class values, but
require a special driver to actually work. Without that driver,
you never get any scan results.
More recently however, Realtek appear to have wisened up and simply
posted a firmware update that makes these devices comply with
normal btusb protocols. The firmware needs to be uploaded on each boot.
Based on Realtek code from https://github.com/lwfinger/rtl8723au_bt
('new' branch).
This enables bluetooth support in the Gigabyte Brix GB-BXBT-2807 which

The Broadcom firmware files are named with firmware version information
encoded into lmp_subver field. So BCM20702B0_002.001.014.0527.0607.hex
would be represented by 0x410e. To allow for an easier decoding of the
actual firmware names, provide an internal table that does the mapping
and request the firmware file by name.
Bluetooth: hci0: BCM20702B0 (002.001.014) build 0607
Now the complicated encoding of lmp_subver will be decoded and turned
into the name and firmware version information from the firmware files.
The previous attempt of using udev->product failed badly since it never
contains any matching entry to the actual hardware or firmware files
distributed by Broadcom in their Windows drivers. It is even worse since
it can change depending on if the internal bootstrapping happened before

This patch adds the device shutdown routine for Intel Bluetooth device.
Some platforms have BT LED issue with Intel Bluetooth device that BT LED goes
off 5 seconds after BT is turned off
For Intel Bluetooth device, the BT LED is turned off when:
- there is no active connection or radio activity
- USB is suspend
So, when the BT is turned off, it takes 5 seconds because USB suspend timeone
is 5 seconds by default. And if the USB suspend is not enabled, BT LED won't be
turned off.
To fix this issue, recently Intel Bluetooth firmware patch had been submitted
to turn off the BT LED immediately by the vendor specific command(0xFC3F). And
this patch sends this command to the device before closing the device.
For backward compatibility of this command with old firmware, this command was
supported before, but it behaves same as HCI_RESET internally. So, it won't be
the problem even if the system doesn't have the latest firmware patch.

The test for BTUSB_DOWNLOADING must be after adding to the wait queue
and setting the TASK_INTERRUPTIBLE state. Otherwise the flag may get
cleared after we test for it and we end up getting a timeout since
schedule_timeout() waits for the full duration. This patch uses a
wait_on_bit_timeout() + wake_up_bit(). To perform the task both
race-free as well as in a much simpler way.
Since there's no global wait_on_bit_timeout() helper yet (even though
all the building blocks for it are in place) this patch creates a
temporary local btusb copy of it until the global one has made it to
upstream trees.

When loading the Intel firmware it can happen that the firmware loading
complete vendor event arrives before the command complete event for the
last firmware fragment.

01 02 fc 03 00 00 00

> HCI Event: Command Complete (0x0e) plen 4
Vendor (0x3f|0x0009) ncmd 31
Status: Success (0x00)
This is mainly caused by the fact that the vendor command and its
command complete event are transported over the bulk endpoints. The
firmware loading complete event however is send over the interrupt
endpoint. So with just bad timing one event arrives before the other.
Currently the code does not account for it. There are precautions for
receiving firmware loading complete event quickly, but not for receiving
it before the command complete.
Introduce an extra flag that tracks when the firmware sending has
completed from the driver point of view and track the completion of
the firmware loading procedure with a different flag. That way the
wakeup can be handled properly.

Instead of setting data->isoc manually, use BTUSB_BROKEN_ISOC to
indicate that isochronous endpoints are not needed for CSR USB
sniffer devices.

The isochronous endpoints are not valid when the Intel Bluetooth
controller boots up in bootloader mode. So just mark these endpoints
as broken and then they will not be configured.

The interrupt interface for the Intel USB bootloader devices is only
enabled after receiving SetInterface(0, AltSetting=0). When this USB
command is not send, then no HCI events will be received.

The module parameters to ignore devices based on USB VID/PID are not
needed at all. So just remove them.

When the Broadcom USB controller has a default address, then set the quirk
so the Bluetooth core knows that controller configuration is required.

The Broadcom BCM20702A0 USB controllers might come with the default
address 00:20:70:02:A0:00 when booting up. If this happens, then warn
about such address being used.

Some Intel Bluetooth controllers come with a default address. If this
address is found, print an error to warn the user about it.
The controller is fully operational, but the danger of duplicate
Bluetooth addresses might causes issues. At least with a clear
error it becomes easier to debug these cases.

This reverts commit ca58e594da.
For some unclear reason this patch tries to add suport for the
product ID 0xe005, but it ends up adding product ID 0x3005 to
all the tables. This is obviously wrong and causing multiple
issues.
The original patch seemed to be fine, but what ended up in 3.15
is not what the patch intended. The commit 0a3658cccd is
already present and adds support for this hardware. This means
only revert of this broken commit is requird.
