Bluetooth: Enable 6LoWPAN support for BT LE devices

2013-12-11T20:57:55+00:00

This is initial version of http://tools.ietf.org/html/draft-ietf-6lo-btle-00 By default the 6LoWPAN support is not activated and user needs to tweak /sys/kernel/debug/bluetooth/hci0/6lowpan file. The kernel needs IPv6 support before 6LoWPAN is usable. Signed-off-by: Jukka Rissanen Signed-off-by: Johan Hedberg Signed-off-by: Marcel Holtmann

Bluetooth: Simplify l2cap_chan initialization for LE CoC

2013-12-05T15:05:36+00:00

The values in l2cap_chan that are used for actually transmitting data only need to be initialized right after we've received an L2CAP Connect Request or just before we send one. The only thing that we need to initialize though bind() and connect() is the chan->mode value. This way all other initializations can be done in the l2cap_le_flowctl_init function (which now becomes private to l2cap_core.c) and the l2cap_le_flowctl_start function can be completely removed. Also, since the l2cap_sock_init function initializes the imtu and omtu to adequate values these do not need to be part of l2cap_le_flowctl_init.

Bluetooth: Fix CID ranges for LE CoC CID allocations

2013-12-05T15:05:36+00:00

LE CoC used differend CIC ranges than BR/EDR L2CAP. The start of the range is the same (0x0040) but the range ends at 0x007f (unlike BR/EDR where it goes all the way to 0xffff). Signed-off-by: Johan Hedberg Signed-off-by: Marcel Holtmann

Bluetooth: Fix LE L2CAP Connect Request handling together with SMP

2013-12-05T15:05:35+00:00

Unlike BR/EDR, for LE when we're in the BT_CONNECT state we may or may not have already have sent the Connect Request. This means that we need some extra tracking of the request. This patch adds an extra channel flag to prevent the request from being sent a second time. Signed-off-by: Johan Hedberg Signed-off-by: Marcel Holtmann

Bluetooth: Introduce L2CAP channel callback for suspending

2013-12-05T15:05:35+00:00

Setting the BT_SK_SUSPEND socket flag from the L2CAP core is causing a dependency on the socket. So instead of doing that, use a channel callback into the socket handling to suspend. Signed-off-by: Johan Hedberg Signed-off-by: Marcel Holtmann

Bluetooth: Track LE L2CAP credits in l2cap_chan

2013-12-05T15:05:34+00:00

This patch adds tracking of L2CAP connection oriented channel local and remote credits to struct l2cap_chan and ensures that connect requests and responses contain the right values. Signed-off-by: Johan Hedberg Signed-off-by: Marcel Holtmann

Bluetooth: Add LE L2CAP flow control mode

2013-12-05T15:05:34+00:00

The LE connection oriented channels have their own mode with its own data transfer rules. In order to implement this properly we need to distinguish L2CAP channels operating in this mode from other modes. Signed-off-by: Johan Hedberg Signed-off-by: Marcel Holtmann

Bluetooth: Add basic LE L2CAP connect request receiving support

2013-12-05T15:05:33+00:00

This patch adds the necessary boiler plate code to handle receiving L2CAP connect requests over LE and respond to them with a proper connect response. Signed-off-by: Johan Hedberg Signed-off-by: Marcel Holtmann

Bluetooth: Add definitions for LE connection oriented channels

2013-12-05T15:05:32+00:00

This patch adds the necessary defines and structs for LE connection oriented channels. Signed-off-by: Johan Hedberg Signed-off-by: Marcel Holtmann

Bluetooth: Add module parameter to enable LE CoC support

2013-12-05T15:05:32+00:00

Along with the L2CAP Connection Oriented Channels features it is now allowed to use both custom fixed CIDs as well as PSM based (connection oriented connections). Since the support for this (with the subsequent patches) is still on an experimental stage, add a module parameter to enable it. Signed-off-by: Johan Hedberg Signed-off-by: Marcel Holtmann
