If RFCOMM_RELEASE_ONHUP flag is on and rfcomm_release_dev is called
before connection is closed, rfcomm_dev is deleted twice from the
rfcomm_dev_list and refcount is messed up. This patch adds a check
before deleting device that the device actually is listed.Signed-off-by: Ville Tervo

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.Signed-off-by: Marcel Holtmann

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.Signed-off-by: Marcel Holtmann

To clearly state the intent of copying from linear sk_buffs, _offset being a
overly long variant but interesting for the sake of saving some bytes.Signed-off-by: Arnaldo Carvalho de Melo
-
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.Signed-off-by: Arnaldo Carvalho de Melo
Signed-off-by: David S. Miller -
For the places where we need a pointer to the transport header, it is
still legal to touch skb->h.raw directly if just adding to,
subtracting from or setting it to another layer header.Signed-off-by: Arnaldo Carvalho de Melo
Signed-off-by: David S. Miller -
For the common, open coded 'skb->h.raw = skb->data' operation, so that we can
later turn skb->h.raw into a offset, reducing the size of struct sk_buff in
64bit land while possibly keeping it as a pointer on 32bit.This one touches just the most simple cases:
skb->h.raw = skb->data;
skb->h.raw = {skb_push|[__]skb_pull}()The next ones will handle the slightly more "complex" cases.

For the places where we need a pointer to the mac header, it is still legal to

regex missed as it had no spaces before nor after '=', ugh.Signed-off-by: Arnaldo Carvalho de Melo

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.Signed-off-by: Jiri Kosina

[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.=================================

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).Signed-off-by: Tim Schmielau

This is the grungy swap all the occurrences in the right places patch that
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
begin turning new stuff on providing nobody reports lots of bugsIf 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[akpm@osdl.org: bluetooth fix]
