[PATCH] Bluetooth: hci_event: Synchronously cancel timers in hci_cmd_complete_evt()

[PATCH] Bluetooth: hci_event: Synchronously cancel timers in hci_cmd_complete_evt()

[Sungwoo Kim]

RFC only.

hci_cmd_complete_evt() and hci_cmd_timeout can interleave, leading to
user-after-free access.

CPU1                  CPU2
hci_cmd_timeout()
                      hci_event_packet()
                      [snip]
                        hci_cmd_complete_evt()
                          handle_cmd_cnt_and_timer()
                            // this is asynchronous
                            cancel_delayed_work(&hdev->cmd_timer)
                        hci_cmd_sync_complete()
                          kfree_skb(hdev->req_skb); // free
  hci_skb_opcode(hdev->req_skb); // use-after-free

To fix this, make cancel_delayed_work() synchronous so it can wait for
the timeout handler.
However, this is not a complete fix because hci_cmd_timeout() resets the
device and queue a new command.
I would like to request for comments the better way to fix this issue.
