Bluetooth: Fix L2CAP LE debugfs entries permissions

2014-06-11T18:54:12+00:00

commit 40b9397a1a61a37917b93e7d57e6f2faf3a086b4 upstream.

0466 was probably meant to be 0644, there's no reason why everyone
except root could write there.

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.

Bluetooth: Fix handling of L2CAP Command Reject over LE

2013-12-10T09:15:44+00:00

If we receive an L2CAP command reject message over LE we should take
appropriate action on the corresponding channel. This is particularly
important when trying to interact with a remote pre-4.1 system using LE
CoC signaling messages. If we don't react to the command reject the
corresponding socket would not be notified until a connection timeout
occurs.

Bluetooth: Fix valid LE PSM check

2013-12-06T06:07:42+00:00

The range of valid LE PSMs is 0x0001-0x00ff so the check should be for
"less than or equal to" instead of "less than".

Bluetooth: Use min_t for calculating chan->mps

2013-12-06T06:07:42+00:00

Since there's a nice convenient helper for calculating the minimum of
two values, let's use that one.

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: Add debugfs controls for LE CoC MPS and Credits

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

This patch adds entries to debugfs to control the values used for the
MPS and Credits for LE Flow Control Mode.

Bluetooth: Fix validating LE PSM values

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

LE PSM values have different ranges than those for BR/EDR. The valid
ranges for fixed, SIG assigned values is 0x0001-0x007f and for dynamic
PSM values 0x0080-0x00ff. We need to ensure that bind() and connect()
calls conform to these ranges when operating on LE CoC sockets.

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 clearing of chan->omtu for LE CoC channels

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

The outgoing MTU should only be set upon channel creation to the initial
minimum value (23) or from a remote connect req/rsp PDU.
