5be3946647 [Bluetooth] Switch to using input_dev->dev.parent
In preparation for struct class_device -> struct device input core
conversion, switch to using input_dev->dev.parent when specifying
device position in sysfs tree.

Also, do not access input_dev->private directly, use helpers and
do not use kfree() on input device, use input_free_device() instead.

3b180bff4c Bluetooth HID: HIDP - don't initialize force feedback
The current implementation of force feedback for HID devices is
USB-transport only and therefore calling hid_ff_init() from hidp code is
not going to work (plus it creates unwanted dependency of hidp on usbhid).
Remove the hid_ff_init() until either the hid-ff is made
transport-independent, or at least support for bluetooth transport is
added.

53c1d4b0b2 [Bluetooth] Attach host adapters to the Bluetooth bus
The Bluetooth host adapters are attached to the Bluetooth class and the
low-level connections are children of these class devices. Having class
devices as parent of bus devices breaks a lot of reasonable assumptions
about sysfs. The host adapters should be attached to the Bluetooth bus
to simplify the dependency resolving. For compatibility an additional
symlink from the Bluetooth class will be used.

0878b6667f [Bluetooth] Fix L2CAP and HCI setsockopt() information leaks
The L2CAP and HCI setsockopt() implementations have a small information
leak that makes it possible to leak kernel stack memory to userspace.

If the optlen parameter is 0, no data will be copied by copy_from_user(),
but the uninitialized stack buffer will be read and stored later. A call
to getsockopt() can now retrieve the leaked information.

To fix this problem the stack buffer given to copy_from_user() must be
initialized with the current settings.

27a884dc3c [SK_BUFF]: Convert skb->tail to sk_buff_data_t
So that it is also an offset from skb->head, reduces its size from 8 to 4 bytes
on 64bit architectures, allowing us to combine the 4 bytes hole left by the
layer headers conversion, reducing struct sk_buff size to 256 bytes, i.e. 4
64byte cachelines, and since the sk_buff slab cache is SLAB_HWCACHE_ALIGN...
:-)

Many calculations that previously required that skb->{transport,network,
mac}_header be first converted to a pointer now can be done directly, being
meaningful as offsets or pointers.

cb3fecc2f2 [PATCH] bluetooth hid quirks: mightymouse quirk
I have a bugreport that scrollwheel of bluetooth version of apple
mightymouse doesn't work.  The USB version of mightymouse works, as there
is a quirk for handling scrollwheel in hid/usbhid for it.

Now that bluetooth git tree is hooked to generic hid layer, it could easily
use the quirks which are already present in generic hid parser, hid-input,
etc.

Below is a simple patch against bluetooth git tree, which adds quirk
handling to current bluetooth hidp code, and sets quirk flags for device
0x05ac/0x030c, which is the bluetooth version of the apple mightymouse.

b40df5743e [PATCH] bluetooth: fix socket locking in hci_sock_dev_event()
[Bluetooth] Fix socket locking in hci_sock_dev_event()

hci_sock_dev_event() uses bh_lock_sock() to lock the socket lock.
This is not deadlock-safe against locking of the same socket lock in
l2cap_connect_cfm() from softirq context. In addition to that,
hci_sock_dev_event() doesn't seem to be called from softirq context,
so it is safe to use lock_sock()/release_sock() instead.

The lockdep warning can be triggered on my T42p simply by switching
the Bluetooth off by the keyboard button.

cd354f1ae7 [PATCH] remove many unneeded #includes of sched.h
After Al Viro (finally) succeeded in removing the sched.h #include in module.h
recently, it makes sense again to remove other superfluous sched.h includes.
There are quite a lot of files which include it but don't actually need
anything defined in there.  Presumably these includes were once needed for
macros that used to live in sched.h, but moved to other header files in the
course of cleaning it up.

To ease the pain, this time I did not fiddle with any header files and only
removed #includes from .c-files, which tend to cause less trouble.

Compile tested against 2.6.20-rc2 and 2.6.20-rc2-mm2 (with offsets) on alpha,
arm, i386, ia64, mips, powerpc, and x86_64 with allnoconfig, defconfig,
allmodconfig, and allyesconfig as well as a few randconfigs on x86_64 and all
configs in arch/arm/configs on arm.  I also checked that no new warnings were
introduced by the patch (actually, some warnings are removed that were emitted
by unnecessarily included header files).

goes with the updates.  At this point we have the same functionality as
before (except that sgttyb() returns speeds not zero) and are ready to

If you are a tty driver author converting an out of tree driver the only
impact should be termios->ktermios name changes for the speed/property
setting functions from your upper layers.

If you are implementing your own TCGETS function before then your driver
was broken already and its about to get a whole lot more painful for you so
please fix it 8)

Also fill in c_ispeed/ospeed on init for most devices, although the current
code will do this for you anyway but I'd like eventually to lose that extra
paranoia

When sending a positive config response it shall include the actual
MTU to be used on this channel. This differs from the Bluetooth 1.1
specification where it was enough to acknowledge the config request.
