Bluetooth: hci_sync: Fix not using conn_timeout

2022-02-24T20:34:28Z

When using hci_le_create_conn_sync it shall wait for the conn_timeout since the connection complete may take longer than just 2 seconds. Also fix the masking of HCI_EV_LE_ENHANCED_CONN_COMPLETE and HCI_EV_LE_CONN_COMPLETE so they are never both set so we can predict which one the controller will use in case of HCI_OP_LE_CREATE_CONN.

Bluetooth: Fix bt_skb_sendmmsg not allocating partial chunks

2022-02-24T20:05:21Z

Since bt_skb_sendmmsg can be used with the likes of SOCK_STREAM it shall return the partial chunks it could allocate instead of freeing everything as otherwise it can cause problems like bellow.

Bluetooth: hci_event: Rework hci_inquiry_result_with_rssi_evt

2022-01-06T13:57:09Z

This rework the handling of hci_inquiry_result_with_rssi_evt to not use a union to represent the different inquiry responses. Signed-off-by: Luiz Augusto von Dentz Tested-by: Soenke Huster Signed-off-by: Marcel Holtmann

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: Add check simultaneous roles support

2021-12-22T22:01:35Z

This attempts to check if the controller can act as both central and peripheral simultaneously and in case it does skip suspending advertising or in case of directed advertising don't fail if scanning. Signed-off-by: Luiz Augusto von Dentz Signed-off-by: Marcel Holtmann

Bluetooth: hci_sync: Add support for waiting specific LE subevents

2021-12-22T22:01:35Z

This adds support for waiting for specific LE subevents instead of command status which may only indicate that the commands is in progress and a different event is used to complete the operation. Signed-off-by: Luiz Augusto von Dentz Signed-off-by: Marcel Holtmann

Bluetooth: hci_sync: Add hci_le_create_conn_sync

2021-12-22T22:01:35Z

This adds hci_le_create_conn_sync and make hci_le_connect use it instead of queueing multiple commands which may conflict with the likes of hci_update_passive_scan which uses hci_cmd_sync_queue. Signed-off-by: Luiz Augusto von Dentz Signed-off-by: Marcel Holtmann

Bluetooth: hci_sync: Push sync command cancellation to workqueue

2021-12-22T22:01:27Z

syzbot reported that hci_cmd_sync_cancel may sleep from the wrong context. To avoid this, create a new work item that pushes the relevant parts into a different context. Note that we keep the old implementation with the name __hci_cmd_sync_cancel as the sleeping behaviour is desired in some cases.

Bluetooth: mgmt: Introduce mgmt_alloc_skb and mgmt_send_event_skb

2021-12-07T16:05:52Z

This introduces mgmt_alloc_skb and mgmt_send_event_skb which are convenient when building MGMT events that have variable length as the likes of skb_put_data can be used to insert portion directly on the skb instead of having to first build an intermediate buffer just to be copied over the skb.

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.
