Bluetooth: HCI: Add HCI_QUIRK_BROKEN_ENHANCED_SETUP_SYNC_CONN quirk

2022-06-09T08:25:27Z

[ Upstream commit 05abad857277dda198063017b00ba5b9fed2c0cb ] This adds HCI_QUIRK_BROKEN_ENHANCED_SETUP_SYNC_CONN quirk which can be used to mark HCI_Enhanced_Setup_Synchronous_Connection as broken even if its support command bit are set since some controller report it as supported but the command don't work properly with some configurations (e.g. BT_VOICE_TRANSPARENT/mSBC).

Bluetooth: hci_event: Fix checking for invalid handle on error status

[ Upstream commit c86cc5a3ec70f5644f1fa21610b943d0441bc1f7 ] Commit d5ebaa7c5f6f6 introduces checks for handle range (e.g HCI_CONN_HANDLE_MAX) but controllers like Intel AX200 don't seem to respect the valid range int case of error status: > HCI Event: Connect Complete (0x03) plen 11 Status: Page Timeout (0x04) Handle: 65535 Address: 94:DB:56:XX:XX:XX (Sony Home Entertainment& Sound Products Inc) Link type: ACL (0x01) Encryption: Disabled (0x00) [1644965.827560] Bluetooth: hci0: Ignoring HCI_Connection_Complete for invalid handle Because of it is impossible to cleanup the connections properly since the stack would attempt to cancel the connection which is no longer in progress causing the following trace: < HCI Command: Create Connection Cancel (0x01|0x0008) plen 6 Address: 94:DB:56:XX:XX:XX (Sony Home Entertainment& Sound Products Inc) = bluetoothd: src/profile.c:record_cb() Unable to get Hands-Free Voice gateway SDP record: Connection timed out > HCI Event: Command Complete (0x0e) plen 10 Create Connection Cancel (0x01|0x0008) ncmd 1 Status: Unknown Connection Identifier (0x02) Address: 94:DB:56:XX:XX:XX (Sony Home Entertainment& Sound Products Inc) < HCI Command: Create Connection Cancel (0x01|0x0008) plen 6 Address: 94:DB:56:XX:XX:XX (Sony Home Entertainment& Sound Products Inc) Fixes: d5ebaa7c5f6f6 ("Bluetooth: hci_event: Ignore multiple conn complete events") Signed-off-by: Luiz Augusto von Dentz Signed-off-by: Marcel Holtmann Signed-off-by: Sasha Levin

Bluetooth: hci_sync: Add a new quirk to skip HCI_FLT_CLEAR_ALL

2022-03-28T08:03:20Z

commit 0eaecfb2e4814d51ab172df3823e35d7c488b6d2 upstream. Some controllers have problems with being sent a command to clear all filtering. While the HCI code does not unconditionally send a clear-all anymore at BR/EDR setup (after the state machine refactor), there might be more ways of hitting these codepaths in the future as the kernel develops.

Bluetooth: MGMT: Fix LE simultaneous roles UUID if not supported

2021-12-22T22:01:35Z

If controller/driver don't support LE simultaneous roles its UUID shall be omitted when responding to MGMT_OP_READ_EXP_FEATURES_INFO. This also rework the support introducing HCI_LE_SIMULTANEOUS_ROLES flag so it can be detected when userspace wants to use or not. Signed-off-by: Luiz Augusto von Dentz Signed-off-by: Marcel Holtmann

Bluetooth: hci_sync: Set Privacy Mode when updating the resolving list

2021-12-07T16:05:51Z

This adds support for Set Privacy Mode when updating the resolving list when HCI_CONN_FLAG_DEVICE_PRIVACY so the controller shall use Device Mode for devices programmed in the resolving list, Device Mode is actually required when the remote device are not able to use RPA as otherwise the default mode is Network Privacy Mode in which only allows RPAs thus the controller would filter out advertisement using identity addresses for which there is an IRK.

Bluetooth: add quirk disabling LE Read Transmit Power

2021-12-07T16:05:51Z

Some devices have a bug causing them to not work if they query LE tx power on startup. Thus we add a quirk in order to not query it and default min/max tx power values to HCI_TX_POWER_INVALID.
