2012-10-15Bluetooth: Add chan->ops->defer()Gustavo Padovan
When DEFER_SETUP is set defer() will trigger an authorization request to the userspace. l2cap_chan_no_defer() is meant to be used when one does not want to support DEFER_SETUP (A2MP for example).

2012-10-15Bluetooth: Move bt_accept_enqueue() to l2cap_sock.cGustavo Padovan
This is part of the move the parent socket usage to l2cap_sock.c The change is safe when it comes to locking, bt_accept_enqueue() is still protected by the parent socket lock inside the l2cap_sock_new_connection_cb() code.

2012-10-12Bluetooth: SMP: Fix setting unknown auth_req bitsJohan Hedberg
When sending a pairing request or response we should not just blindly copy the value that the remote device sent. Instead we should at least make sure to mask out any unknown bits. This is particularly critical from the upcoming LE Secure Connections feature perspective as incorrectly indicating support for it (by copying the remote value) would cause a failure to pair with devices that support it.

Pull networking changes from David Miller: 1) GRE now works over ipv6, from Dmitry Kozlov. 2) Make SCTP more network namespace aware, from Eric Biederman. 3) TEAM driver now works with non-ethernet devices, from Jiri Pirko. 4) Make openvswitch network namespace aware, from Pravin B Shelar. 5) IPV6 NAT implementation, from Patrick McHardy. 6) Server side support for TCP Fast Open, from Jerry Chu and others. 7) Packet BPF filter supports MOD and XOR, from Eric Dumazet and Daniel Borkmann. 8) Increate the loopback default MTU to 64K, from Eric Dumazet. 9) Use a per-task rather than per-socket page fragment allocator for outgoing networking traffic. This benefits processes that have very many mostly idle sockets, which is quite common. From Eric Dumazet. 10) Use up to 32K for page fragment allocations, with fallbacks to smaller sizes when higher order page allocations fail. Benefits are a) less segments for driver to process b) less calls to page allocator c) less waste of space. From Eric Dumazet. 11) Allow GRO to be used on GRE tunnels, from Eric Dumazet. 12) VXLAN device driver, one way to handle VLAN issues such as the limitation of 4096 VLAN IDs yet still have some level of isolation. From Stephen Hemminger. 13) As usual there is a large boatload of driver changes, with the scale perhaps tilted towards the wireless side this time around.
