Bluetooth: Fix properly ignoring LTKs of unknown types

2014-05-31T04:23:29+00:00

In case there are new LTK types in the future we shouldn't just blindly
assume that != MGMT_LTK_UNAUTHENTICATED means that the key is
authenticated. This patch adds explicit checks for each allowed key type
in the form of a switch statement and skips any key which has an unknown
value.

Bluetooth: Clearly distinguish mgmt LTK type from authenticated property

2014-05-23T18:24:04+00:00

On the mgmt level we have a key type parameter which currently accepts
two possible values: 0x00 for unauthenticated and 0x01 for
authenticated. However, in the internal struct smp_ltk representation we
have an explicit "authenticated" boolean value.

To make this distinction clear, add defines for the possible mgmt values
and do conversion to and from the internal authenticated value.

Bluetooth: Make SMP context private to smp.c

2014-05-20T15:44:11+00:00

There are no users of the smp_chan struct outside of smp.c so move it
away from smp.h. The addition of the l2cap.h include to hci_core.c,
hci_conn.c and mgmt.c is something that should have been there already
previously to avoid warnings of undeclared struct l2cap_conn, but the
compiler warning was apparently shadowed away by the mention of
l2cap_conn in the struct smp_chan definition.

Bluetooth: Add missing msecs to jiffies conversion

2014-05-16T15:23:01+00:00

conn_info_age value is calculated in ms, so need to be converted to
jiffies.

Bluetooth: Add support for max_tx_power in Get Conn Info

2014-05-16T04:48:07+00:00

This patch adds support for max_tx_power in Get Connection Information
request. Value is read only once for given connection and then always
returned in response as parameter.

Bluetooth: Avoid polling TX power for LE links

2014-05-16T04:48:06+00:00

TX power for LE links is immutable thus we do not need to query for it
if already have value.

Bluetooth: Add support to get connection information

2014-05-16T04:48:06+00:00

This patch adds support for Get Connection Information mgmt command
which can be used to query for information about connection, i.e. RSSI
and local TX power level.

In general values cached in hci_conn are returned as long as they are
considered valid, i.e. do not exceed age limit set in hdev. This limit
is calculated as random value between min/max values to avoid client
trying to guess when to poll for updated information.

Bluetooth: Increment management interface revision

2014-05-09T12:05:57+00:00

This patch increments the management interface revision due to the
changes with the Device Found management event and other fixes.

Bluetooth: Refactor code for outgoing dedicated bonding

2014-04-11T17:33:08+00:00

Do not always set the MITM protection requirement by default in the
field conn->auth_type, since this will be added later in
hci_io_capa_request_evt(), as part of the requirements specified in
HCI_OP_IO_CAPABILITY_REPLY.

This avoids a hackish exception for the auto-reject case, but doesn't
change the behavior of the code at all.

Bluetooth: Keep msec in DISCOV_LE_TIMEOUT

2014-03-28T07:09:30+00:00

To be consistent, lets use msec for this timeout as well.

Note: This define value is a minimum scan time taken from BT Core spec 4.0,
Vol 3, Part C, chapter 9.2.6
