2020-12-07Bluetooth: Change MGMT security info CMD to be more genericDaniel Winkler1-14/+29
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.

2020-12-07Bluetooth: Use intervals and tx power from mgmt cmdsDaniel Winkler3-15/+30
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.

2020-12-07Bluetooth: Break add adv into two mgmt commandsDaniel Winkler2-11/+371
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.

2020-12-07Bluetooth: Fix attempting to set RPA timeout when unsupportedEdward Vear1-1/+1
During controller initialization, an LE Set RPA Timeout command is sent to the controller if supported. However, the value checked to determine if the command is supported is incorrect. Page 1921 of the Bluetooth Core Spec v5.2 shows that bit 2 of octet 35 of the Supported_Commands field corresponds to the LE Set RPA Timeout command, but currently bit 6 of octet 35 is checked. This patch checks the correct value instead. This issue led to the error seen in the following btmon output during initialization of an adapter (rtl8761b) and prevented initialization from completing. < HCI Command: LE Set Resolvable Private Address Timeout (0x08|0x002e) plen 2 Timeout: 900 seconds > HCI Event: Command Complete (0x0e) plen 4 LE Set Resolvable Private Address Timeout (0x08|0x002e) ncmd 2 Status: Unsupported Remote Feature / Unsupported LMP Feature (0x1a) = Close Index: 00:E0:4C:6B:E5:03 The error did not appear when running with this patch.

2020-11-09Bluetooth: Resume advertising after LE connectionDaniel Winkler3-7/+28
When an LE connection request is made, advertising is disabled and never resumed. When a client has an active advertisement, this is disruptive. This change adds resume logic for client-configured (non-directed) advertisements after the connection attempt. The patch was tested by registering an advertisement, initiating an LE connection from a remote peer, and verifying that the advertisement is re-activated after the connection is established. This is performed on Hatch and Kukui Chromebooks.

2020-10-30Bluetooth: Replace zero-length array with flexible-array memberGustavo A. R. Silva1-1/+2
There is a regular need in the kernel to provide a way to declare having a dynamically sized set of trailing elements in a structure. Kernel code should always use “flexible array members”[1] for these cases. The older style of one-element or zero-length arrays should no longer be used[2].

2020-09-20Bluetooth: Fix auto-creation of hci_conn at Conn Complete eventSonny Sasaka1-6/+11
Currently the code auto-creates hci_conn only if the remote address has been discovered before. This may not be the case. For example, the remote device may trigger connection after reboot at already-paired state so there is no inquiry result found, but it is still correct to create the hci_conn when Connection Complete event is received. A better guard is to check against bredr allowlist. Devices in the allowlist have been given permission to auto-connect.
