Bluetooth: Track current configured LE scan type parameter

2014-03-21T20:02:12+00:00

The LE scan type paramter defines if active scanning or passive scanning
is in use. Track the currently set value so it can be used for decision
making from other pieces in the core.

Bluetooth: Fix passkey endianess in user_confirm and notify_passkey

2014-03-20T06:22:07+00:00

The passkey_notify and user_confirm functions in mgmt.c were expecting
different endianess for the passkey, leading to a big endian bug and
sparse warning in recently added SMP code. This patch converts both
functions to expect host endianess and do the conversion to little
endian only when assigning to the mgmt event struct.

Bluetooth: Make LTK and CSRK only persisent when bonding

2014-03-10T12:57:33+00:00

In case the pairable option has been disabled, the pairing procedure
does not create keys for bonding. This means that these generated keys
should not be stored persistently.

For LTK and CSRK this is important to tell userspace to not store these
new keys. They will be available for the lifetime of the device, but
after the next power cycle they should not be used anymore.

Inform userspace to actually store the keys persistently only if both
sides request bonding.

Bluetooth: Add support for handling signature resolving keys

2014-03-09T19:39:50+00:00

The connection signature resolving key (CSRK) is used for attribute
protocol signed write procedures. This change generates a new local
key during pairing and requests the peer key as well.

Newly generated key and received key will be provided to userspace
using the New Signature Resolving Key management event.

The Master CSRK can be used for verification of remote signed write
PDUs and the Slave CSRK can be used for sending signed write PDUs
to the remote device.

Bluetooth: Remove unnecessary stop_scan_complete function

2014-02-28T18:28:17+00:00

The stop_scan_complete function was used as an intermediate step before
doing the actual connection creation. Since we're using hci_request
there's no reason to have this extra function around, i.e. we can simply
put both HCI commands into the same request.

The single task that the intermediate function had, i.e. indicating
discovery as stopped is now taken care of by a new
HCI_LE_SCAN_INTERRUPTED flag which allows us to do the discovery state
update when the stop scan command completes.

Bluetooth: Add timeout for LE connection attempts

2014-02-28T15:56:42+00:00

LE connection attempts do not have a controller side timeout in the same
way as BR/EDR has (in form of the page timeout). Since we always do
scanning before initiating connections the attempts are always expected
to succeed in some reasonable time.

This patch adds a timer which forces a cancellation of the connection
attempt within 20 seconds if it has not been successful by then. This
way we e.g. ensure that mgmt_pair_device times out eventually and gives
an error response.

Bluetooth: Add defines for LE initiator filter policy

2014-02-28T15:56:42+00:00

This patch adds defines for the initiator filter policy parameter values
of the HCI_LE_Create_Connection command. They will be used in a
subsequent patch to check whether we should have a timeout for the
connection attempt or not.

Bluetooth: Track LE initiator and responder address information

2014-02-28T15:53:07+00:00

For SMP we need the local and remote addresses (and their types) that
were used to establish the connection. These may be different from the
Identity Addresses or even the current RPA. To guarantee that we have
this information available and it is correct track these values
separately from the very beginning of the connection.

For outgoing connections we set the values as soon as we get a
successful command status for HCI_LE_Create_Connection (for which the
patch adds a command status handler function) and for incoming
connections as soon as we get a LE Connection Complete HCI event.

Bluetooth: Use __le64 type for LE random numbers

2014-02-28T10:36:04+00:00

The random numbers in Bluetooth Low Energy are 64-bit numbers and should
also be little endian since the HCI specification is little endian.

Change the whole Low Energy pairing to use __le64 instead of a byte
array.

Bluetooth: Add timer to force power off

2014-02-28T07:41:07+00:00

If some of the cleanup commands caused by mgmt_set_powered(off) never
complete we should still force the adapter to be powered down. This is
rather easy to do since hdev->power_off is already a delayed work
struct. This patch schedules this delayed work if at least one HCI
command was sent by the cleanup procedure.
