Bluetooth: Fix mgmt handling of power on failures

2013-06-20T19:01:28+00:00

commit 96570ffcca0b872dc8626e97569d2697f374d868 upstream.

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: Refactor mgmt_pending_foreach

2013-02-01T17:50:18+00:00

This patch does a trivial refactor in mgmt_pending_foreach function.
It replaces list_for_each_safe by list_for_each_entry_safe, simplifying
the function.

Bluetooth: Fix link security setting when powering on

2013-02-01T17:50:18+00:00

If a controller is powered on while the HCI_AUTO_OFF flag is set the
link security setting (HCI_LINK_SECURITY) might not be in sync with the
actual state of the controller (HCI_AUTH). This patch fixes the issue by
checking for inequality between the intended and actual settings and
sends a HCI_Write_Auth_Enable command if necessary.

Bluetooth: Add support for 128-bit UUIDs in EIR data

2013-02-01T17:50:17+00:00

This patch adds the necessary code for encoding a list of 128-bit UUIDs
into the EIR data.

Bluetooth: Add support for 32-bit UUIDs in EIR data

2013-02-01T17:50:17+00:00

This patch adds the necessary code for inserting a list of 32-bit UUIDs
into the EIR data.

Bluetooth: Refactor UUID-16 list generation into its own function

2013-02-01T17:50:17+00:00

We will need to create three separate UUID lists in the EIR data (for
16, 32 and 128 bit UUIDs) so the code is easier to follow if each list
is generated in their own function.

Bluetooth: Remove useless eir_len variable from EIR creation

2013-02-01T17:50:17+00:00

The amount of data encoded so far in the create_eir() function can be
calculated simply through the difference between the data and ptr
pointer variables. The eir_len variable then becomes essentially
useless.

Bluetooth: Simplify UUID16 list generation for EIR

2013-02-01T17:50:17+00:00

There's no need to use two separate loops to generate a UUID list for
the EIR data. This patch merges the two loops previously used for the
16-bit UUID list generation into a single loop, thus simplifying the
code a great deal.

Bluetooth: Simplify UUID removal code

2013-02-01T17:50:17+00:00

The UUID removal code can be simplified by using
list_for_each_entry_safe instead of list_for_each_safe.
