Bluetooth: Perform L2CAP SDU reassembly without copying data

2011-09-27T21:16:18+00:00

Use sk_buff fragment capabilities to link together incoming skbs
instead of allocating a new skb for reassembly and copying.

The new reassembly code works equally well for ERTM and streaming
mode, so there is now one reassembly function instead of two.

Bluetooth: Move SMP fields to a separate structure

2011-09-21T15:58:12+00:00

The objective is to make the core to have as little as possible
information about SMP procedures and logic. Now, all the SMP
specific information is hidden from the core.

Bluetooth: Fixes l2cap "command reject" reply according to spec

2011-07-11T04:43:25+00:00

There can 3 reasons for the "command reject" reply produced
by the stack. Each such reply should be accompanied by the
relevand data ( as defined in spec. ). Currently there is one
instance of "command reject" reply with reason "invalid cid"
wich is fixed. Also, added clean-up definitions related to the
"command reject" replies.

Bluetooth: Remove L2CAP busy queue

2011-07-07T18:29:06+00:00

The ERTM receive buffer is now handled in a way that does not require
the busy queue and the associated polling code.

Bluetooth: Use event-driven approach for handling ERTM receive buffer

2011-07-07T18:28:56+00:00

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.

Bluetooth: Use bit operations on conn_state

2011-06-16T21:57:15+00:00

Instead of setting bits manually we use set_bit, test_bit, etc.
Also remove L2CAP_ prefix from macros.

Bluetooth: Add key size checks for SMP

2011-06-14T17:54:10+00:00

This patch implements a check in smp cmd pairing request and pairing
response to verify if encryption key maximum size is compatible in both
slave and master when SMP Pairing is requested. Keys are also masked to
the correct negotiated size.

Bluetooth: Add support for SMP timeout

2011-06-14T17:54:05+00:00

This patch adds support for disconnecting the link when SMP procedure
takes more than 30 seconds.

SMP begins when either the Pairing Request command is sent or the
Pairing Response is received, and it ends when the link is encrypted
(or terminated). Vol 3, Part H Section 3.4.

2011-06-13T18:48:25+00:00

used to produce the confirmation value.
