When the virtual HCI is created, the host sends a reset request to the controller. This request is processed by the vhci_send_frame() function. However, this request is send by a different thread, so it might happen that this HCI request will be received before the vendor response is queued in the read queue. This results in the HCI vendor response and HCI reset request inversion in the read queue which leads to improper behavior of btvirt: > dmesg [1754256.640122] Bluetooth: MGMT ver 1.22 [1754263.023806] Bluetooth: MGMT ver 1.22 [1754265.043775] Bluetooth: hci1: Opcode 0x c03 failed: -110 In order to synchronize vhci two-step open/setup process with virtual HCI initialization, this patch adds internal lock when queuing data in the vhci_send_frame() function.
