Bluetooth: Add quirk for disabling Delete Stored Link Key command

2014-01-04T18:10:40+00:00

Some controller pretend they support the Delete Stored Link Key command,
but in reality they really don't support it.

  < HCI Command: Delete Stored Link Key (0x03|0x0012) plen 7
      bdaddr 00:00:00:00:00:00 all 1
  > HCI Event: Command Complete (0x0e) plen 4
      Delete Stored Link Key (0x03|0x0012) ncmd 1
      status 0x11 deleted 0
      Error: Unsupported Feature or Parameter Value

Not correctly supporting this command causes the controller setup to
fail and will make a device not work. However sending the command for
controller that handle stored link keys is important. This quirk
allows a driver to disable the command if it knows that this command
handling is broken.

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.

Add the LMP feature constants for connectionless slave broadcast
and use them for capability testing.

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).

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.

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.

Bluetooth: Add new BT_SNDMTU and BT_RCVMTU socket options

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

This patch adds new socket options for LE sockets since the existing
L2CAP_OPTIONS socket option is not usable for LE. For now, the new
socket options also require LE CoC support to be explicitly enabled to
leave some playroom in case something needs to be changed in a backwards
incompatible way.

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.

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.
