b970c5ba9d Bluetooth: Set HCI_QUIRK_STRICT_DUPLICATE_FILTER for BTUSB_INTEL_NEW
The Intel Snowfield Peak Bluetooth controllers use a strict scanning
filter policy that filters based on Bluetooth device addresses and
not on RSSI.

fad7097228 Bluetooth: btusb: Use wait_on_bit_timeout() for BTUSB_BOOTING
The wait_on_bit_timeout() is a simpler and race-free way of waiting for
a bit to be cleared than the current code in btusb.c. This patch updates
the code to use the helper function (its btusb copy - to be later
updated to use a global one).

a087a98e07 Bluetooth: btusb: Fix race when waiting for BTUSB_DOWNLOADING
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.

74d9daafa5 Bluetooth: btusb: Limit hardware error handling to Intel Snowfield Peak
In general all Intel Bluetooth devices support retrieving of additional
exception information. However for older generations including Wilkens
Peak and Stone Peak it is not as simple. So for now only enable the
Intel specific error handling for Snowfield Peak and later devices.

c561a5753d Bluetooth: ath3k: workaround the compatibility issue with xHCI controller
BugLink: https://bugs.launchpad.net/bugs/1400215

ath3k devices fail to load firmwares on xHCI buses, but work well on
EHCI, this might be a compatibility issue between xHCI and ath3k chips.
As my testing result, those chips will work on xHCI buses again with
this patch.

This workaround is from Qualcomm, they also did some workarounds in
Windows driver.

d0ac9eb72b Bluetooth: btusb: Ignore unknown Intel devices with generic descriptor
The Intel Bluetooth devices use the generic USB device/interface class
descriptors that are assigned to Bluetooth H:2 conforming transports.

T:  Bus=01 Lev=01 Prnt=01 Port=01 Cnt=02 Dev#=  3 Spd=12   MxCh= 0
D:  Ver= 2.01 Cls=e0(wlcon) Sub=01 Prot=01 MxPS=64 #Cfgs=  1

However newer chips have a bootloader stage and require firmware to
be loaded before they are functional. To avoid any confusion for the
users, just ignore unknown Intel Bluetooth devices.

All the released Intel Bluetooth devices have an entry in the device
table identifying their setup and support requirements. The advantage
here is that older kernel can be booted with newer devices without
causing any disturbance.

385a768c3b Bluetooth: btusb: Provide hardware error handler for Intel devices
The Intel Bluetooth controllers can provide an additional exception
info string when a hardware error event occurs. The core will now
call hdev->hw_error to let the driver read out this information.

This change will cause a reset of the hardware to bring it back
into functional state and then read the Intel exception info
string and print it along with the error information.

838f66e3ab Bluetooth: btusb: Remove redundant call to btusb_free_frags()
The btusb_disconnect() callback calls hci_unregister_dev() which in turn
calls btusb_close() if the HCI device is powered. The btusb_close()
function in turn will call btusb_free_frags(). It's therefore
unnecessary to have another call to btusb_free_frags() in the
btusb_disconnect() function. Besides the redundancy the second call
seems to also cause some strange stability issues which this patch then
also fixes.

ce6bb9297c Bluetooth: btusb: Handle out of order firmware loading complete event
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.

< HCI Command: Vendor (0x3f|0x0009) plen 7
        01 02 fc 03 00 00 00
> HCI Event: Vendor (0xff) plen 5
        06 00 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.

cda0dd7809 Bluetooth: btusb: Add firmware loading for Intel Snowfield Peak devices
The Intel Snowfield Peak devices do not come with Bluetooth firmware
loaded and thus require a full download of the operational Bluetooth
firmware when the device is connected via USB.

Snowfield Peak devices start with a bootloader mode that only accepts
a very limited set of HCI commands. The supported commands are enough
to identify the hardware and select the right firmware to load.

Previous patches to the btusb driver allow overwriting the handling
for bulk receive endpoint packets and HCI events processing. The
firmware loading makes heavy use of these new internal callbacks.

This patch also introduces additional internal states to track if the
device is in bootloader or operational mode. This allows for correct
feedback about the firmware loading procedure.

Since this is an unsual USB vendor ID (0x19ff), these dongles are added
via USB_DEVICE macro and not USB_VENDOR_AND_INTERFACE_INFO as done for
mainstream Broadcom based dongles.

The latest known working firmware is BCM20702B0_002.001.014.0527.0557.hex
which needs to be converted using hex2hcd utility and then installed
as /lib/firmware/brcm/BCM20702A0-19ff-0239.hcd to make this device fully
operational.

Bluetooth: hci0: BCM: patching hci_ver=06 hci_rev=2000 lmp_ver=06 lmp_subver=410e
Bluetooth: hci0: BCM: firmware hci_ver=06 hci_rev=222d lmp_ver=06 lmp_subver=410e

With this firmware the device reports support for connectionless slave
broadcast (master and slave) feature used by 3D Glasses and TVs.

  < HCI Command: Read Local Extended Features (0x04|0x0004) plen 1
          Page: 2
  > HCI Event: Command Complete (0x0e) plen 14
        Read Local Extended Features (0x04|0x0004) ncmd 1

            Connectionless Slave Broadcast - Slave
            Synchronization Train
            Synchronization Scan

However there are some flaws with this feature. The Set Event Mask Page 2
command is actually not supported and with that all connectionless slave
broadcast events are always enabled.

  < HCI Command: Set Event Mask Page 2 (0x03|0x0063) plen 8
          Mask: 0x00000000000f0000
            Synchronization Train Received

  > HCI Event: Command Complete (0x0e) plen 4
        Set Event Mask Page 2 (0x03|0x0063) ncmd 1
          Status: Unknown HCI Command (0x01)

In addition the Synchronization Train Received event is actually broken
on this controller. It mixes up the order of parameters. According to the
Bluetooth Core specification the fields are like this:

  struct hci_ev_sync_train_received {
          __u8     status;
          bdaddr_t bdaddr;
          __le32   offset;
          __u8     map[10];
          __u8     lt_addr;
          __le32   instant;
          __le16   interval;
          __u8     service_data;
  } __packed;

This controller however sends the service_data as 5th parameter instead
of having it as last parameter.

  struct hci_ev_sync_train_received {
          __u8     status;
          bdaddr_t bdaddr;
          __le32   offset;
          __u8     map[10];
          __u8     service_data;
          __u8     lt_addr;
          __le32   instant;
          __le16   interval;
  } __packed;

So anybody trying to use this hardware for utilizing connectionless slave
broadcast receivers (aka 3D Glasses), be warned about this shortcoming.

Firmware is extracted from the latest Broadcom BCM4352 Windows driver
by extracting the zip and searching the .hex file names for '17cf'.

The hex file must then be converted to hcd format using the hex2hcd
utility and then moved to /lib/firmware/brcm/.

97307f51d7 Bluetooth: btusb: Add internal recv_event callback for event processing
Some new upcoming drivers need to process HCI events or take extra
actions based on them before handing the event to the Bluetooth core
for processing. The new recv_event callback allows exactly such an
internal behavior.

8b324fa691 Bluetooth: btmrvl: fix race issue while stopping main thread
btmrvl_remove_card() calls kthread_stop() to stop the main thread,
but kthread_should_stop() is checked when all the activities are done
in the main thread before sleeping.
We will have kthread_should_stop() check as soon as main thread is
woken up. This fixes a crash issue caused due to an invalid memory
access while unnecessarily processing interrupts after card removal.

4fcef8ed75 Bluetooth: Fix issue with Roper Class 1 Bluetooth Dongle
The Roper Class 1 Bluetooth Dongle is another device that claims to
support Bluetooth 1.2 specification, but does not support the HCI
command for reading the local supported commands.

  < HCI Command: Read Local Version Information (0x04|0x0001) plen 0
  > HCI Event: Command Complete (0x0e) plen 12
      Read Local Version Information (0x04|0x0001) ncmd 1

      LMP Version: 1.2 (0x2) LMP Subversion: 0x757
      Manufacturer: Silicon Wave (11)

It clearly claims Bluetooth 1.2 support and in that regard has the
same issue as the AVM BlueFritz! USB devices (Silicon Wave based),
but the HCI Read Local Supported Commands command fails.

  < HCI Command: Read Local Supported Commands (0x04|0x0002) plen 0
  > HCI Event: Command Status (0x0f) plen 4
      Read Local Supported Commands (0x04|0x0002) status 0x01 ncmd 1

Use the HCI_QUIRK_BROKEN_LOCAL_COMMANDS quirk for these devices and
the failing command will be skipped.

 removing a line in a structure.
 
 Other than that, a few minor driver core and debugfs changes.  There are
 some ath9k patches coming in through this tree that have been acked by

The firmware was extracted from a Windows 7 32-bit installation
and converted from 'hex' to 'hcd' for use in Linux.

The firmware is named "BCM20702A0_001.001.024.0156.0204.hex"
and is located in "%SYSTEMROOT%\system32\drivers\"
(md5 d126e6c4e0e669d76c38cf9377f76b7f)
(sha1 145d1850b2785a953233b409e7ff77786927c7d2)

The firmware file is also available as a download at
http://support.ts.fujitsu.com/Download/
contained in "FTS_WIDCOMMBluetoothSoftware_6309000_1072149.zip"

Search for the file Win32/bcbtums-win7x86-brcm.inf in the archive,
look for the vendor and product ID of your adapter, see the section
'devices' in that file to find out what device name it uses. See
the device entry in the inf file (in my case it was 'RAMUSBE031')
to find out which hex file you need to convert to hcd for upload

'hcd' file should be placed at "brcm/BCM20702A0-0489-e031.hcd"
inside the firmware directory (e.g. "/lib/firmware")

dc759613b0 Bluetooth: btmrvl add firmware dump support
This patch adds firmware dump support for marvell
bluetooth chipset. Currently only SD8897 is supported.
This is implemented based on dev_coredump, a new mechnism
introduced in kernel 3.18rc3

Firmware dump can be trigger by
echo 1 > /sys/kernel/debug/bluetooth/hci*/config/fw_dump
and when the dump operation is completed, data can be read by
cat /sys/class/devcoredump/devcd*/data

We have prepared following script to divide fw memory
dump data into multiple files based on memory type.

 [root]# cat btmrvl_split_dump_data.sh
 #!/bin/bash
 # usage: ./btmrvl_split_dump_data.sh dump_data

 fw_dump_data=$1

 mem_type="ITCM DTCM SQRAM APU CIU ICU MAC EXT7 EXT8 EXT9 EXT10 EXT11 EXT12 EXT13 EXTLAST"

 for name in ${mem_type[@]}
 do
         sed -n "/Start dump $name/,/End dump/p" $fw_dump_data  > tmp.$name.log
         if [ ! -s tmp.$name.log ]
                 then
                         rm -rf tmp.$name.log
                 else
                         # Remove the describle info "Start dump" and "End dump"
                         sed '1d' tmp.$name.log | sed '$d' > /data/$name.log
                         if [ -s /data/$name.log ]
                         then
                                 echo "generate /data/$name.log"
                         else
                                 sed '1d' tmp.$name.log | sed '$d' > /var/$name.log
                                 echo "generate /var/$name.log"
                         fi
                         rm -rf tmp.$name.log

The firmware was extracted from a Windows 8.1 64-bit installation
and converted from 'hex' to 'hcd' for use in Linux.

Under Windows it also identifies itself as BCM20702A0,
but the firmware is named "BCM20702A1_001.002.014.1315.1356.hex"
and is located in "%SYSTEMROOT%\system32\drivers\"
(md5 67cf6bfdae61c4bb819a66da984f7913)
(sha1 5f74cc6a9a3bf19ee0f8c3d01e4be34c609b188f)

The same firmware file is also available as a download at
http://www.asrock.com/mb/Intel/Z87E-ITX/?cat=Download&os=All
marked as "Bluetooth driver ver:12.0.0.7820"

'hcd' file should be placed at "brcm/BCM20702A0-13d3-3404.hcd"
inside the firmware directory (e.g. "/lib/firmware")

b509c02d0f Bluetooth: HCI H5 peer reset detection
H5 Specification says:
If a SYNC message is received while in the Active State, it is
assumed that the peer device has reset. The local device should
therefore perform a full reset of the upper stack, and start Link
Establishment again at the Uninitialized State. Upon entering the
Active State, the first packet sent shall have its SEQ and ACK
numbers set to zero.

This patch resets the HCI H5 driver data/state to unitialized and
reports an HCI hardware error event to notify the upper stack that
HCI synchronization has been lost. H5 will be re-synchronized and
upper stack should generate an HCI Reset command.

803b58367f Bluetooth: btusb: Implement driver internal packet reassembly
When receiving USB interrupt, bulk or isochronous packet, they normally
come in fragments. So far the driver just handed each fragment off to
the hci_recv_fragment function of the Bluetooth core. That function is
however so specific that is does not belong in the core. This patch
implements the same reassembly logic in the driver.

In addition this fixes a long standing bug where multiple complete
packets are received within a single USB packet.

The complete TX URB handling is done via a switch statement in the
btusb_send_frame function. To allow for more clear separation between
control, bulk and isoc URBs, split them into allocation and submission.

Previously the inc_tx function has been used for tracking in-flight
URB for HCI commands and ACL data packets. Convert that into a common
function that either submits the URB or queues it when needed.

This provides the flexibility to allow vendor specific hdev->send_frame
callbacks without having to duplicate the whole URB handling logic.

In this expression: seq = (seq - 1) % 8
seq (u8) is implicitly converted to an int in the arithmetic operation.
So if seq value is 0, operation is ((0 - 1) % 8) => (-1 % 8) => -1.
The new seq value is 0xff which is an invalid ACK value, we expect 0x07.
It leads to frequent dropped ACK and retransmission.
Fix this by using '&' binary operator instead of '%'.

8500d791c4 Bluetooth: Fix crash in the Marvell driver initialization codepath
btmrvl_add_card() function calls kthread_run that might return error
(e.g. if current thread is killed). If one tries to use the error
value as a pointer then invalid memory access oops happens.

Check kthread_run() return value, if it is an error then release resources
correctly.

TEST=boot computer with BT modules enabled. I see the error message that
BT device initialization failed. Now kernel does not crash. Hint: to enable
BT run 'rmmod btmrvl_sdio; modprobe btmrvl_sdio'

72dd2b2a44 Bluetooth: Fix endian and alignment issue with ath3k version handling
The ath3k driver is treating the version information badly when it
comes to loading the right firmware version and comparing that it
actually matches with the hardware.

Initially this showed up as this:

  CHECK   drivers/bluetooth/ath3k.c
drivers/bluetooth/ath3k.c:373:17: warning: cast to restricted __le32
drivers/bluetooth/ath3k.c:435:17: warning: cast to restricted __le32

However when fixing this by actually using __packed and __le32 for
the ath3_version structure, more issues came up:

  CHECK   drivers/bluetooth/ath3k.c
drivers/bluetooth/ath3k.c:381:32: warning: incorrect type in assignment (different base types)
drivers/bluetooth/ath3k.c:381:32:    expected restricted __le32 [usertype] rom_version
drivers/bluetooth/ath3k.c:381:32:    got int [signed] <noident>
drivers/bluetooth/ath3k.c:382:34: warning: incorrect type in assignment (different base types)
drivers/bluetooth/ath3k.c:382:34:    expected restricted __le32 [usertype] build_version
drivers/bluetooth/ath3k.c:382:34:    got int [signed] <noident>
drivers/bluetooth/ath3k.c:386:28: warning: restricted __le32 degrades to integer
drivers/bluetooth/ath3k.c:386:56: warning: restricted __le32 degrades to integer

This patch fixes every instance of the firmware version handling and
makes sure it is endian safe and uses proper unaligned access.

We should suspend hci device and purge remaining data in tx queue
before enabling host sleep in firmware. If any data is sent to
firmware after host sleep is activated, firmware may end up
sending a TX_DONE interrupt to driver. If this interrupt gets
delivered to host while the SDIO host controller is suspending,
it may crash the system.

Conversely, in resume handler, we should resume hci device after
host sleep is de-activated.

For some unclear reason this patch tries to add suport for the

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

10d4c6736e Bluetooth: btusb: Add Broadcom patch RAM support
After hardware reset, some BCM Bluetooth adapters obtain their initial firmware
from OTPROM chip. Once this initial firmware is running, the firmware can be
further upgraded over HCI interface with .hcd files provided by Broadcom. This
is also known as "patch RAM" support. This change implements that.

If the .hcd file is not found in /lib/firmware, BCM Bluetooth adapter continues
to operate with the initial firmware. Sample kernel log:
  hotplug: sys=firmware act=add fw=brcm/BCM20702A0-0a5c-22be.hcd dev=...
  Bluetooth: hci0: BCM: patch brcm/BCM20702A0-0a5c-22be.hcd not found

If the .hcd file is found, btusb driver pushes it to the BCM Bluetooth adapter and
it starts using the new firmware. Sample kernel log:
  hotplug: sys=firmware act=add fw=brcm/BCM20702A0-0a5c-22be.hcd dev=...
  Bluetooth: hci0: BCM: patching hci_ver=06 hci_rev=1000 lmp_ver=06 lmp_subver=220e
  Bluetooth: hci0: BCM: firmware hci_ver=06 hci_rev=1389 lmp_ver=06 lmp_subver=220e

Above, we can see that hci_rev goes from 1000 to 1389 as a result of the upgrade.

3c49aa852e Revert "Bluetooth: Enable autosuspend for Intel Bluetooth device"
This reverts commit d2bee8fb6e.

Enabling autosuspend for Intel Bluetooth devices has been shown to not
work reliable. It does work for some people with certain combinations
of USB host controllers, but for others it puts the device to sleep and
it will not wake up for any event.

These events can be important ones like HCI Inquiry Complete or HCI
Connection Request. The events will arrive as soon as you poke the
device with a new command, but that is not something we can do in
these cases.

Initially there were patches to the xHCI USB controller that fixed
this for some people, but not for all. This could be well a problem
somewhere in the USB subsystem or in the USB host controllers or
just plain a hardware issue somewhere. At this moment we just do
not know and the only safe action is to revert this patch.

b075dd40c9 Bluetooth: allocate static minor for vhci
Commit bfacbb9 (Bluetooth: Use devname:vhci module alias for virtual HCI
driver) added the module alias to hci_vhci module so it's possible to
create the /dev/vhci node. However creating an alias without
specifying the minor doesn't allow us to create the node ahead,
triggerring module auto-load when it's first accessed.

Starting with depmod from kmod 16 we started to warn if there's a
devname alias without specifying the major and minor.

Let's do the same done for uhid, kvm, fuse and others, specifying a
fixed minor. In systems with systemd as the init the following will
happen: on early boot systemd will call "kmod static-nodes" to read
/lib/modules/$(uname -r)/modules.devname and then create the nodes. When
first accessed these "dead" nodes will trigger the module loading.

81cac64ba2 Bluetooth: Deal with USB devices that are faking CSR vendor
There exists a set of Bluetooth USB devices that show up on the USB
bus as 0a12:0001 and identify themselves as devices from CSR. However
they are not. When sending Read Local Version command they now have
a split personality and say they are from Broadcom.

  < HCI Command: Read Local Version Information (0x04|0x0001) plen 0
  > HCI Event: Command Complete (0x0e) plen 12
      Read Local Version Information (0x04|0x0001) ncmd 1
      status 0x00
      HCI Version: 2.0 (0x3) HCI Revision: 0x3000
      LMP Version: 2.0 (0x3) LMP Subversion: 0x420b
      Manufacturer: Broadcom Corporation (15)

The assumption is that they are neither CSR nor Broadcom based devices
and that they are designed and manufactured by someone else.

For the most parts they follow the Bluetooth HCI specification and
can be used as standard Bluetooth devices. However they have the
minor problem that the Delete Stored Link Key command is not working
as it should.

During the Bluetooth controller setup, this command is needed if
stored link keys are supported. For these devices it has to be
assumed that this is broken and so just set a quirk to clearly
indicate the behavior. After that the setup can just proceed.

Now the trick part is to detect these faulty devices since we do
not want to punish all CSR and all Broadcom devices. The original
devices do actually work according to the specification.

What is known so far is that these broken devices set the USB bcdDevice
revision information to 1.0 or less.

T:  Bus=02 Lev=01 Prnt=01 Port=08 Cnt=03 Dev#=  9 Spd=12   MxCh= 0
D:  Ver= 2.00 Cls=e0(wlcon) Sub=01 Prot=01 MxPS=64 #Cfgs=  1
P:  Vendor=0a12 ProdID=0001 Rev= 1.00
S:  Manufacturer=Bluetooth v2.0
S:  Product=Bluetooth V2.0 Dongle

T:  Bus=05 Lev=01 Prnt=01 Port=01 Cnt=01 Dev#=  2 Spd=12   MxCh= 0

P:  Vendor=0a12 ProdID=0001 Rev= 0.07

In case of CSR devices, the bcdDevice revision contains the firmware
build ID and that is normally a higher value. If the bcdDevice revision
is 1.0 or less, then an extra setup stage is checking if Read Local
Version returns CSR manufacturer information. If not then it will be
assumed that this is a broken device and the Delete Stored Link Key
command will be marked as broken.

d2bee8fb6e Bluetooth: Enable autosuspend for Intel Bluetooth device
This patch enables autosuspend for Intel Bluetooth device.

After btusb is loaded for Intel Bluetooth device, the power/control
attribute contains "on" value by default which disables the autosuspend.
Based on the USB PM document(Documentation/usb/power-management.txt),
kernel disabled the autosuspend for all devices other than hub by default.

"The USB specification states that all USB devices must support power
management.  Nevertheless, the sad fact is that many devices do not
support it very well.  You can suspend them all right, but when you
try to resume them they disconnect themselves from the USB bus or
they stop working entirely.  This seems to be especially prevalent
among printers and scanners, but plenty of other types of device have
the same deficiency.

For this reason, by default the kernel disables autosuspend (the
power/control attribute is initialized to "on") for all devices other
than hubs.  Hubs, at least, appear to be reasonably well-behaved in
this regard."

This document also described how the driver can enables the autosuspend
by using an USB api.

"Drivers can enable autosuspend for their devices by calling

	usb_enable_autosuspend(struct usb_device *udev);

in their probe() routine, if they know that the device is capable of
suspending and resuming correctly.  This is exactly equivalent to
writing "auto" to the device's power/control attribute."

For Intel Bluetooth device, the autosuspend needs to be enabled so the
device can transit to LPM(Low Power Mode) and ULPM(Ultra LPM) states after
receiving suspend message from the host.

433a9389a1 Bluetooth: btmrvl: use cal-data from device-tree instead of conf file
Some ARM versions of Chromebook need to download a new calibration
data from host driver to firmware. They do have EEPROM but still
need a piece of new calibration data in test mode.

The cal-data is platform dependent. It's simpler and more feasible
to use device tree based cal-data instead of configuration file
based cal-data.

This patch remove configuration file based cal-data downloading
and replace it using cal-data from device tree.

When CONFIG_OF is not selected, or the specific property is not
present in the device tree, the calibration downloading will not
happen.
