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: Add hci_cmd_sync_cancel to public API

2021-12-03T18:41:59Z

After transfer errors it makes sense to cancel an ongoing synchronous command that cannot complete anymore. To permit this, export the old hci_req_sync_cancel function as hci_cmd_sync_cancel in the API. Signed-off-by: Benjamin Berg Signed-off-by: Luiz Augusto von Dentz

Bluetooth: hci_sync: Convert MGMT_OP_SET_CONNECTABLE to use cmd_sync

2021-11-16T14:13:34Z

This makes MGMT_OP_SET_CONNEABLE use hci_cmd_sync_queue instead of use a dedicated connetable_update work. Signed-off-by: Luiz Augusto von Dentz Signed-off-by: Marcel Holtmann

Bluetooth: hci_sync: Convert MGMT_OP_SET_DISCOVERABLE to use cmd_sync

2021-11-16T14:13:34Z

This makes MGMT_OP_SET_DISCOVERABLE use hci_cmd_sync_queue instead of use a dedicated discoverable_update work. Signed-off-by: Luiz Augusto von Dentz Signed-off-by: Marcel Holtmann

Bluetooth: hci_sync: Rework hci_suspend_notifier

2021-10-29T14:52:00Z

This makes hci_suspend_notifier use the hci_*_sync which can be executed synchronously which is allowed in the suspend_notifier and simplifies a lot of the handling since the status of each command can be checked inline so no other work need to be scheduled thus can be performed without using of a state machine.

Bluetooth: hci_sync: Rework init stages

2021-10-29T14:52:00Z

This moves the init stages to use the hci_sync infra and in addition to that have the stages as function tables so it is easier to change the command sequence. Signed-off-by: Luiz Augusto von Dentz Signed-off-by: Marcel Holtmann
