Bluetooth: Change MGMT security info CMD to be more generic

2020-12-07T15:01:42Z

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

2020-12-07T15:01:38Z

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

2020-12-07T15:01:33Z

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. Reviewed-by: Sonny Sasaka Signed-off-by: Daniel Winkler Signed-off-by: Marcel Holtmann Signed-off-by: Johan Hedberg

Bluetooth: Break add adv into two mgmt commands

2020-12-07T15:01:28Z

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

2020-12-07T15:01:25Z

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.

Bluetooth: Interleave with allowlist scan

2020-12-07T15:00:43Z

This patch implements the interleaving between allowlist scan and no-filter scan. It'll be used to save power when at least one monitor is registered and at least one pending connection or one device to be scanned for. The durations of the allowlist scan and the no-filter scan are controlled by MGMT command: Set Default System Configuration. The default values are set randomly for now.

Bluetooth: L2CAP: Fix calling sk_filter on non-socket based channel

2020-09-25T18:21:55Z

Only sockets will have the chan->data set to an actual sk, channels like A2MP would have its own data which would likely cause a crash when calling sk_filter, in order to fix this a new callback has been introduced so channels can implement their own filtering if necessary.

Bluetooth: Emit controller suspend and resume events

2020-09-13T07:55:26Z

Emit controller suspend and resume events when we are ready for suspend and we've resumed from suspend. The controller suspend event will report whatever suspend state was successfully entered. The controller resume event will check the first HCI event that was received after we finished preparing for suspend and, if it was a connection event, store the address of the peer that caused the event. If it was not a connection event, we mark the wake reason as an unexpected event. Here is a sample btmon trace with these events: @ MGMT Event: Controller Suspended (0x002d) plen 1 Suspend state: Page scanning and/or passive scanning (2) @ MGMT Event: Controller Resumed (0x002e) plen 8 Wake reason: Remote wake due to peer device connection (2) LE Address: CD:F3:CD:13:C5:9A (OUI CD-F3-CD) Signed-off-by: Abhishek Pandit-Subedi Reviewed-by: Miao-chen Chou Signed-off-by: Marcel Holtmann
