2015-04-03Bluetooth: bnep: Handle BNEP connection setup requestGrzegorz Kolodziejczyk
With this patch kernel will be able to handle setup request. This is needed if we would like to handle control mesages with extension headers. User space will be only resposible for reading setup data and checking if scenario is conformance to specification (dst and src device bnep role). In case of new user space, setup data must be leaved(peek msg) on queue. New bnep session will be responsible for handling this data.

2015-04-03Bluetooth: bnep: Add support to extended headers of control framesGrzegorz Kolodziejczyk
Handling extended headers of control frames is required BNEP functionality. This patch refractor bnep rx frame handling function. Extended header for control frames shouldn't be omitted as it was previously done. Every control frame should be checked if it contains extended header and then every extension should be parsed separately.

2015-04-03Bluetooth: bnep: Add support for get bnep features via ioctlGrzegorz Kolodziejczyk
This is needed if user space wants to know supported bnep features by kernel, e.g. if kernel supports sending response to bnep setup control message. By now there is no possibility to know supported features by kernel in case of bnep. Ioctls allows only to add connection, delete connection, get connection list, get connection info. Adding connection if it's possible (establishing network device connection) is equivalent to starting bnep session. Bnep session handles data queue of transmit, receive messages over bnep channel. It means that if we add connection the received/transmitted data will be parsed immediately. In case of get bnep features we want to know before session start, if we should leave setup data on socket queue and let kernel to handle with it, or in case of no setup handling support, if we should pull this message and handle setup response within user space.

2015-02-03Bluetooth: Fix potential NULL dereferenceJohan Hedberg
The bnep_get_device function may be triggered by an ioctl just after a connection has gone down. In such a case the respective L2CAP chan->conn pointer will get set to NULL (by l2cap_chan_del). This patch adds a missing NULL check for this case in the bnep_get_device() function.

2014-11-02Bluetooth: Introduce BT_BREDR and BT_LE config optionsMarcel Holtmann
The current kernel options do not make it clear which modules are for Bluetooth Classic (BR/EDR) and which are for Bluetooth Low Energy (LE).

2013-03-08Bluetooth: discard bt_sock_unregister() errorsDavid Herrmann
After we successfully registered a socket via bt_sock_register() there is no reason to ever check the return code of bt_sock_unregister(). If bt_sock_unregister() fails, it means the socket _is_ already unregistered so we have what we want, don't we? Also, to get bt_sock_unregister() to fail, another part of the kernel has to unregister _our_ socket. This is sooo _wrong_ that it will break way earlier than when we unregister our socket.
