This cause 'No Bonding' to be used if userspace has not yet been paired
with remote device since the l2cap socket used to create the rfcomm
session does not have any security level set.

In function l2cap_get_conf_opt() and l2cap_add_conf_opt() the address of
opt->val sometimes is not at the edge of 2-bytes/4-bytes, so 2-bytes/4 bytes
access will cause data misalignment exeception. Use get_unaligned_le16/32
and put_unaligned_le16/32 function to avoid data misalignment execption.

When initiating dedicated bonding a L2CAP raw socket with HIGH security
level is used. The kernel is supposed to trigger the authentication
request in this case but this doesn't happen currently for non-SSP
(pre-2.1) devices. The reason is that the authentication request happens
in the remote extended features callback which never gets called for
non-SSP devices. This patch fixes the issue by requesting also
authentiation in the (normal) remote features callback in the case of
non-SSP devices.
This rule is applied only for HIGH security level which might at first
seem unintuitive since on the server socket side MEDIUM is already
enough for authentication. However, for the clients we really want to
prefer the server side to decide the authentication requrement in most
cases, and since most client sockets use MEDIUM it's better to be
avoided on the kernel side for these sockets. The important socket to
request it for is the dedicated bonding one and that socket uses HIGH
security level.
The patch is based on the initial investigation and patch proposal from
Andrei Emeltchenko <endrei.emeltchenko@nokia.com>.

Current Bluetooth code assembles fragments of big L2CAP packets
in l2cap_recv_acldata and then checks allowed L2CAP size in
assemled L2CAP packet (pi->imtu < skb->len).
The patch moves allowed L2CAP size check to the early stage when
we receive the first fragment of L2CAP packet. We do not need to
reserve and keep L2CAP fragments for bad packets.
Updated version after comments from Mat Martineau <mathewm@codeaurora.org>
and Gustavo Padovan <padovan@profusion.mobi>.
Trace below is received when using stress tools sending big
fragmented L2CAP packets.

L2CAP ERTM sockets can be opened with the SOCK_STREAM socket type,
which is a mandatory request for ERTM mode.
However, these sockets still have SOCK_SEQPACKET read semantics when
bt_sock_recvmsg() is used to pull data from the receive queue. If the
application is only reading part of a frame, then the unread portion
of the frame is discarded. If the application requests more bytes
than are in the current frame, only the current frame's data is
returned.
This patch utilizes common code derived from RFCOMM's recvmsg()
function to make L2CAP SOCK_STREAM reads behave like RFCOMM reads (and
other SOCK_STREAM sockets in general). The application may read one
byte at a time from the input stream and not lose any data, and may
also read across L2CAP frame boundaries.

This commit adds a bt_sock_stream_recvmsg() function for use by any
Bluetooth code that uses SOCK_STREAM sockets. This code is copied
from rfcomm_sock_recvmsg() with minimal modifications to remove
RFCOMM-specific functionality and improve readability.
L2CAP (with the SOCK_STREAM socket type) and RFCOMM have common needs
when it comes to reading data. Proper stream read semantics require
that applications can read from a stream one byte at a time and not
lose any data. The RFCOMM code already operated on and pulled data
from the underlying L2CAP socket, so very few changes were required to
make the code more generic for use with non-RFCOMM data over L2CAP.
Applications that need more awareness of L2CAP frame boundaries are
still free to use SOCK_SEQPACKET sockets, and may verify that they
connection did not fall back to basic mode by calling getsockopt().

When receiving a rfcomm connection with the old dund deamon a
inconsistent lock state happens. That's because interrupts were already
disabled by l2cap_conn_start() when rfcomm_sk_state_change() try to lock
the spin_lock.
As result we may have a inconsistent lock state for l2cap_conn_start()
after rfcomm_sk_state_change() calls bh_lock_sock() and disable interrupts
as well.

As we don't have any error control on the Streaming mode, i.e., we don't
need to keep a copy of the skb for later resending we don't need to
call skb_clone() on it.
Then we can go one further here, and dequeue the skb before sending it,
that also means we don't need to look to sk->sk_send_head anymore.
The patch saves memory and time when sending Streaming mode data, so
it is good to mainline.

remote_tx_win is intended to be set on receipt of an L2CAP
configuration request. The value is used to determine the size of the
transmit window on the remote side of an ERTM connection, so L2CAP
can stop sending frames when that remote window is full.
An incorrect remote_tx_win value will cause the stack to not fully
utilize the tx window (performance impact), or to overfill the remote
tx window (causing dropped frames or a disconnect).
This patch removes an extra setting of remote_tx_win when a
configuration response is received. The transmit window has a
different meaning in a response - it is an informational value
less than or equal to the local tx_win.

Incoming configuration values must be converted to native CPU order
before use. This fixes a bug where a little-endian MPS value is
compared to a native CPU value. On big-endian processors, this
can cause ERTM and streaming mode segmentation to produce PDUs
that are larger than the remote stack is expecting, or that would
produce fragmented skbs that the current FCS code cannot handle.

Certain headsets such as the Motorola H350 will reject SCO and eSCO
connection requests while the ACL is transitioning from sniff mode
to active mode. Add synchronization so that SCO and eSCO connection
requests will wait until the ACL has fully transitioned to active mode.

means that L2CAP Extended features are enabled by default now.
