Vinicius Costa Gomes cc110922da Bluetooth: Change signature of smp_conn_security()
To make it clear that it may be called from contexts that may not have
any knowledge of L2CAP, we change the connection parameter, to receive
a hci_conn.

This also makes it clear that it is checking the security of the link.

Mathias Krause 792039c73c Bluetooth: L2CAP - Fix info leak via getsockname()
The L2CAP code fails to initialize the l2_bdaddr_type member of struct
sockaddr_l2 and the padding byte added for alignment. It that for leaks
two bytes kernel stack via the getsockname() syscall. Add an explicit
memset(0) before filling the structure to avoid the info leak.

Mat Martineau a6a5568c03 Bluetooth: Lock the L2CAP channel when sending
The ERTM and streaming mode transmit queue must only be accessed while
the L2CAP channel lock is held.  Locking the channel before calling
l2cap_chan_send ensures that multiple threads cannot simultaneously
manipulate the queue when sending and receiving concurrently.

L2CAP channel locking had previously moved to the l2cap_chan struct
instead of the associated socket, so some of the old socket locking
can also be removed in this patch.

Gustavo Padovan a7d7723ae7 Bluetooth: notify userspace of security level change
It fixes L2CAP socket based security level elevation during a
connection. The HID profile needs this (for keyboards) and it is the only
way to achieve the security level elevation when using the management
interface to talk to the kernel (hence the management enabling patch
being the one that exposes this issue).

It enables the userspace a security level change when the socket is
already connected and create a way to notify the socket the result of the
request. At the moment of the request the socket is made non writable, if
the request fails the connections closes, otherwise the socket is made
writable again, POLL_OUT is emmited.

Mat Martineau 61d6ef3e34 Bluetooth: Make better use of l2cap_chan reference counting
L2CAP sockets contain a pointer to l2cap_chan that needs to be
reference counted in order to prevent a possible dangling pointer when
the channel is freed.

There were a few other cases where an l2cap_chan pointer on the stack
was dereferenced after a call to l2cap_chan_del. Those pointers are
also now reference counted.

Paul Moore 6230c9b4f8 bluetooth: Properly clone LSM attributes to newly created child connections
The Bluetooth stack has internal connection handlers for all of the various
Bluetooth protocols, and unfortunately, they are currently lacking the LSM
hooks found in the core network stack's connection handlers.  I say
unfortunately, because this can cause problems for users who have have an
LSM enabled and are using certain Bluetooth devices.  See one problem
report below:

 * http://bugzilla.redhat.com/show_bug.cgi?id=741703

In order to keep things simple at this point in time, this patch fixes the
problem by cloning the parent socket's LSM attributes to the newly created
child socket.  If we decide we need a more elaborate LSM marking mechanism
for Bluetooth (I somewhat doubt this) we can always revisit this decision
in the future.

feature in L2CAP Info RSP when hs enabled. EWS option is included in L2CAP
Config Req if tx_win (which is set via socket) bigger then standard default
value (63) && hs enabled && remote side supports EWS feature.

Using EWS selects extended control field in L2CAP.

Mat Martineau e328140fda Bluetooth: Use event-driven approach for handling ERTM receive buffer
This change moves most L2CAP ERTM receive buffer handling out of the
L2CAP core and in to the socket code.  It's up to the higher layer
(the socket code, in this case) to tell the core when its buffer is
full or has space available.  The recv op should always accept
incoming ERTM data or else the connection will go down.

Within the socket layer, an skb that does not fit in the socket
receive buffer will be temporarily stored.  When the socket is read
from, that skb will be placed in the receive buffer if possible.  Once
adequate buffer space becomes available, the L2CAP core is informed
and the ERTM local busy state is cleared.

Receive buffer management for non-ERTM modes is unchanged.

Jaikumar Ganesh 14b12d0b98 Bluetooth: Add BT_POWER L2CAP socket option.
Add BT_POWER socket option used to control the power
characteristics of the underlying ACL link. When the remote end
has put the link in sniff mode and the host stack wants to send
data we need need to explicitly exit sniff mode to work well with
certain devices (For example, A2DP on Plantronics Voyager 855).
However, this causes problems with HID devices.

Hence, moving into active mode when sending data, irrespective
of who set the sniff mode has been made as a socket option. By
default, we will move into active mode. HID devices can set the
L2CAP socket option to prevent this from happening.

Currently, this has been implemented for L2CAP sockets. This has been
tested with incoming and outgoing L2CAP sockets for HID and A2DP.

Based on discussions on linux-bluetooth and patches submitted by
Andrei Emeltchenko.
