Bluetooth: btusb: Add support for Foxconn/Lenovo BCM43142A0 (105b:e065)
Recently salvaged this 'BCM43142A0' WiFi/Bluetooth module from a Lenovo laptop
and noticed it doesn't work automatically, because the USB IDs are missing
from btusb.c.
Plugging in the adapter on Linux 4.1 (dmesg):

Support for the chipset was added in commit 88f9b65 and a similar BCM43142
based device was added in commit 8f0c304.
To work around the issue, I got the firmware
(BCM43142A0_001.001.011.0122.0153) off a Windows installation of Broadcom
bluetooth driver and converted it to a .hcd -file via. hex2hcd and placed it
in /lib/firmware/brcm/BCM.hcd. After that:
$ echo "105b e065 0 19ff 0239" > /sys/bus/usb/drivers/btusb/new_id
...(plug in the adapter)

Bam, now it works for me!

Support for the chipset was added in commit 88f9b65 and a similar BCM43142
based device was added in commit 8f0c304.
To work around the issue, I got the firmware
(BCM43142A0_001.001.011.0122.0153) off a Windows installation of Broadcom
bluetooth driver and converted it to a .hcd -file via. hex2hcd and placed it
in /lib/firmware/brcm/BCM.hcd. After that:
$ echo "105b e065 0 19ff 0239" > /sys/bus/usb/drivers/btusb/new_id
...(plug in the adapter)
usb 3-3.3.3: new full-speed USB device number 91 using xhci_hcd

Bam, now it works for me!

networking: introduce and use skb_put_data()
A common pattern with skb_put() is to just want to memcpy()
some data into the new space, introduce skb_put_data() for
this.
An spatch similar to the one for skb_put_zero() converts many
of the places using it:

identifier p, p2;
expression len, skb, data;
type t, t2;
@@
(
-p = skb_put(skb, len);

Bluetooth: btusb: Always fallback to alt 1 for WBS
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 baac6276c0a9
("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 461f95f04f19 ("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.

Bluetooth: btusb: Fix and detect most of the Chinese Bluetooth controllers
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

Bluetooth: btusb: Add workaround for remote-wakeup issues with Barrot 8041a02 fake CSR controllers
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.

Bluetooth: btusb: Add workaround for remote-wakeup issues with Barrot 8041a02 fake CSR controllers
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.

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.

networking: make skb_put & friends return void pointers
It seems like a historic accident that these return unsigned char *,
and in many places that means casts are required, more often than not.
Make these functions (skb_put, __skb_put and pskb_put) return void *
and remove all the casts across the tree, adding a (u8 *) cast only
where the unsigned char pointer was used directly, all done with the
following spatch:
@@
expression SKB, LEN;
typedef u8;
identifier fn = { skb_put, __skb_put };
@@
- *(fn(SKB, LEN))
+ *(u8 *)fn(SKB, LEN)
@@
expression E, SKB, LEN;
identifier fn = { skb_put, __skb_put };
type T;
@@
- E = ((T *)(fn(SKB, LEN)))
+ E = fn(SKB, LEN)
which actually doesn't cover pskb_put since there are only three
users overall.
A handful of stragglers were converted manually, notably a macro in
drivers/isdn/i4l/isdn_bsdcomp.c and, oddly enough, one of the many
instances in net/bluetooth/hci_sock.c. In the former file, I also
had to fix one whitespace problem spatch introduced.

networking: add and use skb_put_u8()
Joe and Bjørn suggested that it'd be nicer to not have the
cast in the fairly common case of doing
*(u8 *)skb_put(skb, 1) = c;
Add skb_put_u8() for this case, and use it across the code,
using the following spatch:
@@
expression SKB, C, S;
typedef u8;
identifier fn = {skb_put};
fresh identifier fn2 = fn ## "_u8";
@@
- *(u8 *)fn(SKB, S) = C;
+ fn2(SKB, 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
initialized.

networking: introduce and use skb_put_data()
A common pattern with skb_put() is to just want to memcpy()
some data into the new space, introduce skb_put_data() for
this.
An spatch similar to the one for skb_put_zero() converts many
of the places using it:

Bluetooth: btusb: Apply QCA Rome patches for some ATH3012 models
In commit f44cb4b19ed4 ("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.

Bluetooth: btusb: Apply QCA Rome patches for some ATH3012 models
In commit f44cb4b19ed4 ("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.

Bluetooth: btusb: Some Qualcomm Bluetooth adapters stop working
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 b40f58b97386
("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.

networking: add and use skb_put_u8()

Add skb_put_u8() for this case, and use it across the code,
using the following spatch:
@@
expression SKB, C, S;
typedef u8;
identifier fn = {skb_put};
fresh identifier fn2 = fn ## "_u8";
@@
- *(u8 *)fn(SKB, S) = C;
+ fn2(SKB, 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
initialized.

Bluetooth: btusb: Apply QCA Rome patches for some ATH3012 models
In commit f44cb4b19ed4 ("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.
Fixes: commit f44cb4b19ed4 ("Bluetooth: btusb: Fix quirk for Atheros 1525/QCA6174")

Bluetooth: btusb: Apply QCA Rome patches for some ATH3012 models
In commit f44cb4b19ed4 ("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.

Bluetooth: btusb: Fix and detect most of the Chinese Bluetooth controllers
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

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
IC markings on 0x7558: FR3191AHAL 749H15143 (???)
