Bluetooth: Change MGMT security info CMD to be more generic

2020-12-07T15:01:42+00:00

For advertising, we wish to know the LE tx power capabilities of the
controller in userspace, so this patch edits the Security Info MGMT
command to be more generic, such that other various controller
capabilities can be included in the EIR data. This change also includes
the LE min and max tx power into this newly-named command.

The change was tested by manually verifying that the MGMT command
returns the tx power range as expected in userspace.

Bluetooth: Query LE tx power on startup

2020-12-07T15:01:38+00:00

Queries tx power via HCI_LE_Read_Transmit_Power command when the hci
device is initialized, and stores resulting min/max LE power in hdev
struct. If command isn't available (< BT5 support), min/max values
both default to HCI_TX_POWER_INVALID.

This patch is manually verified by ensuring BT5 devices correctly query
and receive controller tx power range.

Bluetooth: Use intervals and tx power from mgmt cmds

2020-12-07T15:01:33+00:00

This patch takes the min/max intervals and tx power optionally provided
in mgmt interface, stores them in the advertisement struct, and uses
them when configuring the hci requests. While tx power is not used if
extended advertising is unavailable, software rotation will use the min
and max advertising intervals specified by the client.

This change is validated manually by ensuring the min/max intervals are
propagated to the controller on both hatch (extended advertising) and
kukui (no extended advertising) chromebooks, and that tx power is
propagated correctly on hatch. These tests are performed with multiple
advertisements simultaneously.

Bluetooth: Break add adv into two mgmt commands

2020-12-07T15:01:28+00:00

This patch adds support for the new advertising add interface, with the
first command setting advertising parameters and the second to set
advertising data. The set parameters command allows the caller to leave
some fields "unset", with a params bitfield defining which params were
purposefully set. Unset parameters will be given defaults when calling
hci_add_adv_instance. The data passed to the param mgmt command is
allowed to be flexible, so in the future if bluetoothd passes a larger
structure with new params, the mgmt command will ignore the unknown
members at the end.

This change has been validated on both hatch (extended advertising) and
kukui (no extended advertising) chromebooks running bluetoothd that
support this new interface. I ran the following manual tests:
- Set several (3) advertisements using modified test_advertisement.py
- For each, validate correct data and parameters in btmon trace
- Verified both for software rotation and extended adv

Automatic test suite also run, testing many (25) scenarios of single and
multi-advertising for data/parameter correctness.

Bluetooth: Add helper to set adv data

2020-12-07T15:01:25+00:00

We wish to handle advertising data separately from advertising
parameters in our new MGMT requests. This change adds a helper that
allows the advertising data and scan response to be updated for an
existing advertising instance.

2020-12-07T15:00:52+00:00

This patch adds code to handle the active scan during interleave
scan. The interleave scan will be canceled when users start active scan,
and it will be restarted after active scan stopped.
