Bluetooth: Remove unneeded flag

2013-06-22T23:23:53+00:00

Remove HCI_LINK_KEYS flag since using HCI_MGMT is enough for test that
user space expects the kernel managing link keys.

Bluetooth: Mgmt Device Found Event

2013-06-22T23:23:52+00:00

We only want to send Mgmt Device Found Events if we are running the
Device Discovery procedure (started by the MGMT Start Discovery
Command). Inquiry or LE scanning triggered by HCI raw interface (e.g.
hcitool) or kernel internals should not send Mgmt Device Found Events.

Bluetooth: Make mgmt_stop_discovery_failed static

2013-06-22T23:23:51+00:00

mgmt_stop_discovery_failed is now only used in mgmt.c so we can
make it a local function. This patch also moves the mgmt_stop_
discovery_failed definition up in mgmt.c to avoid forward
declaration.

Bluetooth: Update stop_discovery to use HCI request

2013-06-22T23:23:51+00:00

This patch modifies the stop_discovery function so it uses the HCI
request framework.

The HCI request is built according to the current discovery state
(inquiry, LE scanning or name resolving) and a complete callback is
register to handle the command complete event for the stop discovery
command. This way, we move all stop_discovery mgmt handling code
spread in hci_event.c to a single place in mgmt.c.

Bluetooth: Use HCI request in interleaved discovery

2013-06-22T23:23:50+00:00

In order to have a better HCI error handling in interleaved discovery
functionality, we should use the HCI request framework.

This patch updates le_scan_disable_work function so it uses the
HCI request framework instead of the hci_send_cmd helper. A complete
callback is registered (le_scan_disable_work_complete function) so we
are able to trigger the inquiry procedure (if we are running the
interleaved discovery) or to stop the discovery procedure (if we are
running LE-only discovery).

This patch also removes the extra logic in hci_cc_le_set_scan_enable
to trigger the inquiry procedure and the mgmt_interleaved_discovery
function since they become useless.

Bluetooth: Move discovery macros to hci_core.h

2013-06-22T23:23:50+00:00

Some of discovery macros will be used in hci_core so we need to
define them in common place such as hci_core.h. Thus, this patch
moves discovery macros to hci_core.h and also adds the DISCOV_
prefix to them.

Bluetooth: Update start_discovery to use HCI request

2013-06-22T23:23:50+00:00

This patch modifies the start_discovery function so it uses the HCI
request framework.

We build the HCI request according to the discovery type (add inquiry
or LE scan HCI commands) and run the HCI request. We also register
the start_discovery_complete callback which handles mgmt command
complete events for this command. This way, we move all start_
discovery mgmt handling code spread in hci_event.c to a single place
in mgmt.c.

This patch also merges the LE-only and interleaved discovery type
cases since these cases are pretty much the same now.

Bluetooth: Fix mgmt handling of power on failures

2013-06-12T14:20:55+00:00

If hci_dev_open fails we need to ensure that the corresponding
mgmt_set_powered command gets an appropriate response. This patch fixes
the missing response by adding a new mgmt_set_powered_failed function
that's used to indicate a power on failure to mgmt. Since a situation
with the device being rfkilled may require special handling in user
space the patch uses a new dedicated mgmt status code for this.

Bluetooth: Fix checks for LE support on LE-only controllers

2013-06-12T14:20:54+00:00

LE-only controllers do not support extended features so any kind of host
feature bit checks do not make sense for them. This patch fixes code
used for both single-mode (LE-only) and dual-mode (BR/EDR/LE) to use the
HCI_LE_ENABLED flag instead of the "Host LE supported" feature bit for
LE support tests.
