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.

Bluetooth: Fix sending write_le_host_supporte for LE-only controllers

2013-04-23T23:20:12+00:00

The Bluetooth Core Specification (4.0) defines the Write LE Host
Supported HCI command as only available for controllers supporting
BR/EDR. This is further reflected in the Read Local Extended Features
HCI command also not being available for LE-only controllers. In other
words, host-side LE support is implicit for single-mode LE controllers
and doesn't have explicit HCI-level enablement.

This patch ensures that the LE setting is always exposed as enabled
through mgmt and returns a "rejected" response if user space tries to
toggle the setting. The patch also ensures that Write LE Host Supported
is never sent for LE-only controllers.

Bluetooth: Add LE scan type macros

2013-04-18T04:16:25+00:00

This patch adds macros for active and passive LE scan type values.
The LE_SCAN_PASSIVE was also defined since it will be used in future
by LE connection routine and GAP Observer Role support.

Bluetooth: Change LE scanning timeout macros

2013-04-18T04:15:05+00:00

Define LE scanning timeout macros in jiffies just like we do for
others timeout macros.

Bluetooth: rename hci_conn_put to hci_conn_drop

2013-04-11T19:34:15+00:00

We use _get() and _put() for device ref-counting in the kernel. However,
hci_conn_put() is _not_ used for ref-counting, hence, rename it to
hci_conn_drop() so we can later fix ref-counting and introduce
hci_conn_put().

hci_conn_hold() and hci_conn_put() are currently used to manage how long a
connection should be held alive. When the last user drops the connection,
we spawn a delayed work that performs the disconnect. Obviously, this has
nothing to do with ref-counting for the _object_ but rather for the
keep-alive of the connection.

But we really _need_ proper ref-counting for the _object_ to allow
connection-users like rfcomm-tty, HIDP or others.

Bluetooth: Fix PIN/Confirm/Passkey response parameters

2013-03-18T18:36:05+00:00

The only valid mgmt response to these pairing related commands is a
mgmt_cmd_complete and the returned parameters should contain the address
and address type of the remote device.

Bluetooth: Simplify address parameters of user_pairing_resp()

2013-03-18T18:36:04+00:00

Instead of passing the bdaddr and bdaddr_type as separate parameters to
user_pairing_resp it's simpler to just pass the original mgmt_addr_info
struct which contains both values.

Bluetooth: Fix fast connectable state when enabling page scan

2013-03-18T18:36:04+00:00

When powering on or enabling page scan we need to ensure that the page
scan parameters are as they should be. This is because some controllers
do not properly reset these values upon HCI_Reset. Since the
write_scan_parameters function is now called from several new places it
also checks for the >= 1.2 HCI version requirement before sending the
commands.

Bluetooth: Fix updating page scan parameters when not necessary

2013-03-18T18:36:03+00:00

Now that the current page scan parameters are stored in struct hci_dev
we should check against those values before sending new HCI commands to
change them.
