c257820291 Bluetooth: Fix H4 crash from incoming UART packets
This patch adds a check HCI_UART_REGISTERED before reading UART data in
the HCI UART H4 driver. UART data could arrive when inside the
hci_uart_tty_ioctl function after calling test_and_set_bit for
HCI_UART_PROTO_SET but before the hci_uart_set_proto function has
returned.

e58b9a25ee ASoC/extcon: arizona: Fix interaction between HPDET and headphone outputs
This patch series covers both ASoC and extcon subsystems and fixes an
 interaction between the HPDET function and the headphone outputs - we
 really shouldn't run HPDET while the headphone is active.  The first
 patch is a refactoring to make the extcon side easier.

77189df431 bluetooth: btmrvl_sdio: look for sd8688 firmware in proper location
The firmware images are shared with libertas_sdio WiFi chip and used to be
in libertas/ subtree in linux-firmware. As btmrvl_sdio used to look into
the linux-firmware root, it ended up being unsuccessful. Since the
firmware files are not specific to the libertas hardware, they're being
moved into mrvl/ now.

4f73bc4dd3 tty: Added a CONFIG_TTY option to allow removal of TTY
The option allows you to remove TTY and compile without errors. This
saves space on systems that won't support TTY interfaces anyway.
bloat-o-meter output is below.

The bulk of this patch consists of Kconfig changes adding "depends on
TTY" to various serial devices and similar drivers that require the TTY
layer.  Ideally, these dependencies would occur on a common intermediate
symbol such as SERIO, but most drivers "select SERIO" rather than
"depends on SERIO", and "select" does not respect dependencies.

bloat-o-meter output comparing our previous minimal to new minimal by
removing TTY.  The list is filtered to not show removed entries with awk
'$3 != "-"' as the list was very long.

f327b340e3 TTY: hci_ldisc, remove invalid check in open
hci_ldisc's open checks if tty_struct->disc_data is set. And if so it
returns with an error. But nothing ensures disc_data to be NULL. And
since ld->ops->open shall be called only once, we do not need the
check at all. So remove it.

Note that this is not an issue now, but n_tty will start using the
disc_data pointer and this invalid 'if' would trigger then rendering
TTYs over BT unusable.

Pull networking changes from David Miller:

 1) GRE now works over ipv6, from Dmitry Kozlov.

 2) Make SCTP more network namespace aware, from Eric Biederman.

 3) TEAM driver now works with non-ethernet devices, from Jiri Pirko.

 4) Make openvswitch network namespace aware, from Pravin B Shelar.

 5) IPV6 NAT implementation, from Patrick McHardy.

 6) Server side support for TCP Fast Open, from Jerry Chu and others.

 7) Packet BPF filter supports MOD and XOR, from Eric Dumazet and Daniel
    Borkmann.

 8) Increate the loopback default MTU to 64K, from Eric Dumazet.

 9) Use a per-task rather than per-socket page fragment allocator for
    outgoing networking traffic.  This benefits processes that have very
    many mostly idle sockets, which is quite common.

    From Eric Dumazet.

10) Use up to 32K for page fragment allocations, with fallbacks to
    smaller sizes when higher order page allocations fail.  Benefits are
    a) less segments for driver to process b) less calls to page
    allocator c) less waste of space.

    From Eric Dumazet.

11) Allow GRO to be used on GRE tunnels, from Eric Dumazet.

12) VXLAN device driver, one way to handle VLAN issues such as the
    limitation of 4096 VLAN IDs yet still have some level of isolation.
    From Stephen Hemminger.

13) As usual there is a large boatload of driver changes, with the scale
    perhaps tilted towards the wireless side this time around.

As pointed out by Gustavo and Marcel, all Apple-specific Broadcom
devices seen so far have the same interface class, subclass and
protocol numbers. This patch adds an entry which matches all of them,
using the new USB_VENDOR_AND_INTERFACE_INFO() macro.

In particular, this patch adds support for the MacBook Pro Retina
(05ac:8286), which is not in the present list.

we are in low-power state. When the controller enters this state it will
send a sleep message after which the host is not allowed to send any
other packets until a wakeup request has been sent and the woken message
received as a response to it. The wakeup requests are re-sent
periodically until a woken message is received.

1) One final sync of wireless and bluetooth stuff from John Linville.
   These changes have all been in his tree for more than a week, and
   therefore have had the necessary -next exposure.  John was just away
   on a trip and didn't have a change to send the pull request until a
   day or two ago.

2) Put back some defines in user exposed header file areas that were
   removed during the tokenring purge.  From Stephen Hemminger and Paul
   Gortmaker.

3) A bug fix for UDP hash table allocation got lost in the pile due to
   one of those "you got it..  no I've got it.." situations.  :-)

   From Tim Bird.

4) SKB coalescing in TCP needs to have stricter checks, otherwise we'll
   try to coalesce overlapping frags and crash.  Fix from Eric Dumazet.

5) RCU routing table lookups can race with free_fib_info(), causing
   crashes when we deref the device pointers in the route.  Fix by
   releasing the net device in the RCU callback.  From Yanmin Zhang.

e1f12eb6ba USB: Disable hub-initiated LPM for comms devices.
Hub-initiated LPM is not good for USB communications devices.  Comms
devices should be able to tell when their link can go into a lower power
state, because they know when an incoming transmission is finished.
Ideally, these devices would slam their links into a lower power state,
using the device-initiated LPM, after finishing the last packet of their
data transfer.

If we enable the idle timeouts for the parent hubs to enable
hub-initiated LPM, we will get a lot of useless LPM packets on the bus
as the devices reject LPM transitions when they're in the middle of
receiving data.  Worse, some devices might blindly accept the
hub-initiated LPM and power down their radios while they're in the
middle of receiving a transmission.

The Intel Windows folks are disabling hub-initiated LPM for all USB
communications devices under a xHCI USB 3.0 host.  In order to keep
the Linux behavior as close as possible to Windows, we need to do the
same in Linux.

Set the disable_hub_initiated_lpm flag for for all USB communications
drivers.  I know there aren't currently any USB 3.0 devices that
implement these class specifications, but we should be ready if they do.

2a8ff6112d Bluetooth: btmrvl: configure default host sleep parameters
Currently debugfs commands "hscfgcmd" and "gpiogap" are provided
for host sleep configuration. But if user doesn't configure host
sleep parameters using these commands, host sleep activation is
failed during suspend (support for suspend and resume handlers is
added in next patch).

Default host sleep configuration is done during driver initialisation
in this patch.

0dea0141a9 Bluetooth: vhci: Ignore return code of nonseekable_open()
The comment in ./fs/open.c clearly states that nonseekable_open() will
never fail. Therefore, we can safely ignore the return code. This is the
recommended way to deal with nonseekable_open().
Our current code looks like nonseekable_open() is checked for the return
code. However, if we check the return code, we must also kfree() our
private data if the open fails. To avoid this overhead and to avoid
confusion, we simply drop the return code and return 0.

6935e0f518 Bluetooth: Remove redundant hdev->parent field
We initialize the "struct device" in hci_alloc_dev() for a long time now
so we can access hdev->dev.parent directly. Hence, we can drop the
temporary field hdev->parent which is used in no other place than
hci_add_sysfs().

SET_HCIDEV_DEV() is never called after registering a device by the
drivers so we do not overwrite internal device-state. Furthermore,
hdev->dev is initialized to 0 by kzalloc() inside hci_alloc_dev() so the
default behavior with dev.parent = NULL is kept.

234e340582 simple_open: automatically convert to simple_open()
Many users of debugfs copy the implementation of default_open() when
they want to support a custom read/write function op.  This leads to a
proliferation of the default_open() implementation across the entire
tree.

Now that the common implementation has been consolidated into libfs we
can replace all the users of this function with simple_open().

This replacement was done with the following semantic patch:

<smpl>
@ open @
identifier open_f != simple_open;
identifier i, f;
@@
-int open_f(struct inode *i, struct file *f)
-{
(
-if (i->i_private)
-f->private_data = i->i_private;
|
-f->private_data = i->i_private;
)
-return 0;
-}

@ has_open depends on open @
identifier fops;
identifier open.open_f;
@@
struct file_operations fops = {
...
-.open = open_f,
+.open = simple_open,
...
};

    From: Oliver Neukum <oliver@neukum.org>
    Date: Wed, 21 Sep 2011 11:37:15 +0200
    Subject: [PATCH] btusb: add device entry for Broadcom SoftSailing

and noticed it wasn't working on an HP Elitebook.  Looking into the patch I
noticed a very subtle typo in the ids.  The patch has '0x05ac' instead of
'0x0a5c'.  A snippet of the lsusb -v output also shows this:

Bus 002 Device 003: ID 0a5c:21e1 Broadcom Corp.
Device Descriptor:
  bLength                18
  bDescriptorType         1
  bcdUSB               2.00
  bDeviceClass          255 Vendor Specific Class
  bDeviceSubClass         1
  bDeviceProtocol         1
  bMaxPacketSize0        64
  idVendor           0x0a5c Broadcom Corp.
  idProduct          0x21e1
  bcdDevice            1.12
  iManufacturer           1 Broadcom Corp
  iProduct                2 BCM20702A0
  iSerial                 3 60D819F0338C
  bNumConfigurations      1

Looking at other Broadcom ids, the fix matches them whereas the original patch
matches Apple's ids.

Tested on an HP Elitebook 8760w.  The btusb binds and the userspace stuff loads
correctly.

Do not close protocol driver until device has been unregistered.

This fixes a race between tty_close and hci_dev_open which can result in
a NULL-pointer dereference.

The line discipline closes the protocol driver while we may still have
hci_dev_open sleeping on the req_lock mutex resulting in a NULL-pointer
dereference when lock is acquired and hci_init_req called.

Bug is 100% reproducible using hciattach and a disconnected serial port:

0. # hciattach -n ttyO1 any noflow

1. hci_dev_open called from hci_power_on grabs req lock
2. hci_init_req executes but device fails to initialise (times out
   eventually)
3. hci_dev_open is called from hci_sock_ioctl and sleeps on req lock
4. hci_uart_tty_close detaches protocol driver and cancels init req
5. hci_dev_open (1) releases req lock
6. hci_dev_open (3) grabs req lock, calls hci_init_req, which triggers oops
   when request is prepared in hci_uart_send_frame

e9b9cfa157 Bluetooth: Remove HCI-owner field
After unregistering an hci_dev object a bluetooth driver does not have
any callbacks in the hci_dev structure left over. Therefore, there is no
need to keep a reference to the module.

Previously, we needed this to protect the hci-destruct callback.
However, this callback is no longer available so we do not need this
owner field, anymore.  Drivers now call hci_unregister_dev() and they
are done with the object.

797fe796c4 Bluetooth: uart-ldisc: Fix memory leak and remove destruct cb
We currently leak the hci_uart object if HCI_UART_PROTO_SET is never set
because the hci-destruct callback will then never be called.  This fix
removes the hci-destruct callback and frees the driver internal private
hci_uart object directly on tty-close. We call hci_unregister_dev() here
so the hci-core will never call our callbacks again (except destruct).
Therefore, we can safely free the driver internal data right away and
set the destruct callback to NULL.

Instead of using the hci-destruct callback we free our private driver

However, there is no reason to keep our *private* driver data alive if

1a609a0a93 Bluetooth: bfusb: Free driver_data on USB shutdown
This frees the private driver data on USB shutdown instead of using the
hci-destruct callback. We already call usb_set_intfdata(intf, NULL) but
we do not do the same with the hci object. This would be totally safe,
though.

After calling hci_unregister_dev()/hci_free_dev() the hdev object will
never call any callback of us again except the destruct callback.
Therefore, we can safely set the destruct callback to NULL and free the
driver data right away.  This allows to unload the module without
waiting for the hdev device to be released.

bf18c7118c Bluetooth: vhci: Free driver_data on file release
This removes the hci-destruct callback and instead frees the private
driver data in the vhci_release file release function. There is no
reason to keep private driver data available if the driver has already
shut down.

After vhci_release is called our module can be unloaded. The only reason
it is kept alive is the hci-core having a module-ref on us because of
our destruct callback. However, this callback only frees
hdev->driver_data. That is, we wait for the hdev-device to get destroyed
to free our internal driver-data. In fact, the hci-core does never touch
hdev->driver_data so it doesn't care if it is NULL. Therefore, we simply
free it when unloading the driver.

Another important fact is that the hdev core does not call any callbacks
other than the destruct-cb after hci_unregister_dev() has been called.
So there is no function of our module that will be called nor does the
hci-core touch hdev->driver_data. Hence, no other code can touch
hdev->driver_data after our cleanup so the destruct callback is
definitely unnecessary here.

fa0fb93f2a Bluetooth: btusb: fix bInterval for high/super speed isochronous endpoints
For high-speed/super-speed isochronous endpoints, the bInterval
value is used as exponent, 2^(bInterval-1). Luckily we have
usb_fill_int_urb() function that handles it correctly. So we just
call this function to fill in the RX URB.

3a7cbd50f7 freezer: don't unnecessarily set PF_NOFREEZE explicitly
Some drivers set PF_NOFREEZE in their kthread functions which is
completely unnecessary and racy - some part of freezer code doesn't
consider cases where PF_NOFREEZE is set asynchronous to freezer
operations.

In general, there's no reason to allow setting PF_NOFREEZE explicitly.
Remove them and change the documentation to note that setting
PF_NOFREEZE directly isn't allowed.

-v2: Dropped change to twl4030-irq.c as it no longer uses PF_NOFREEZE.

"device got disconnected" aren't things to worry about).

usb_submit_urb() returns -ENODEV when a usb device is disconnected. In
commit 4935f1c164 ("Bluetooth: btusb: be
quiet on device disconnect") I stopped treating that return as an error
in the three btusb_*_complete() functions.

It turns out btusb_send_frame() generates a similar error if the system
is suspended while the bluetooth usb device is enabled. The sensible
thing to do here seems to be to treat -ENODEV (and -EPERM) just like the
btusb_*_complete() functions now do.

9fd481e03c Bluetooth: Allow ACL packets over USB in HCI_RAW mode
Removed tests which prevent transmission of ACL packets
when the device is in HCI_RAW mode. These tests verified that
there are ACL or LE links currently tracked by the HCI
connection manager. However, a HCI_RAW mode device does not
use the connection manager. In these circumstances, the connection
counts will be zero, and thus, transmitted ACL packets dropped.

The acl_num test is actually a vestige of a previous bulk URB
scheme that is no longer used by this driver (bulk URBs were not
started until at least one ACL connection was created). This was
incompatible with some endpoint implementations and was dropped -
see commit 43c2e57f94.

The utility of these tests is marginal - currently, the hci tx
scheduler cannot send an ACL or LE packet for an untracked connection
(except if the device is in HCI_RAW mode).

Lastly, no other transport layer driver enforces these same tests.

Today I noticed that the usb bluetooth adapter (BCM2046B1) on my 2011
mac mini was not working. I've created a patch to get it going.

a63b723d02 Bluetooth: Add MacBookAir4,1 support
This patch against current git adds the hardware ID for the Apple
MacBookAir4,1, released in July 2011. The device features a BCM2046
USB chip. The patch was inspired by the previous modifications adding
support for the MacBookAir3,x.

8be964d236 Bluetooth: Fixed BT ST Channel reg order
Reordered the BT ST channel registration, to make sure that the
event channel is registered before all others. This prevents a
situation where incoming events may cause kernel panic in the ST
driver if the event channel is not yet registered to handle
incoming events.In addition, the deregistration of the channels
was also modified, to be in the reversed order of the registration,
to allow the event channel to be the last one unregistered.

5b1b0b812a PM / Runtime: Add macro to test for runtime PM events
This patch (as1482) adds a macro for testing whether or not a
pm_message value represents an autosuspend or autoresume (i.e., a
runtime PM) event.  Encapsulating this notion seems preferable to
open-coding the test all over the place.
