      Bluetooth: move adv_instance_cnt read within the device lock · 4bd80d7a
      Niels Dossche authored
      The field adv_instance_cnt is always accessed within a device lock,
      except in the function add_advertising. A concurrent remove of an
      advertisement with adding another one could result in the if check
      "if a new instance was actually added" to not trigger, resulting
      in not triggering the "advertising added event".

      Bluetooth: hci_event: Add missing locking on hdev in hci_le_ext_adv_term_evt · 728abc01
      Niels Dossche authored
      Both hci_find_adv_instance and hci_remove_adv_instance have a comment
      above their function definition saying that these two functions require
      the caller to hold the hdev->lock lock. However, hci_le_ext_adv_term_evt
      does not acquire that lock and neither does its caller hci_le_meta_evt
      (hci_le_meta_evt calls hci_le_ext_adv_term_evt via an indirect function
      call because of the lookup in hci_le_ev_table).
      
      The other event handlers all acquire and release the hdev->lock and they
      follow the rule that hci_find_adv_instance and hci_remove_adv_instance
      must be called while holding the hdev->lock lock.
      
      The solution is to make sure hci_le_ext_adv_term_evt also acquires and
      releases the hdev->lock lock. The check on ev->status which logs a
      warning and does an early return is not covered by the lock because
      other functions also access ev->status without holding the lock.

      Bluetooth: mediatek: fix the conflict between mtk and msft vendor event · e4412654
      Sean Wang authored
      There is a conflict between MediaTek wmt event and msft vendor extension
      logic in the core layer since 145373cb ("Bluetooth: Add framework for
      Microsoft vendor extension") was introduced because we changed the type of
      mediatek wmt event to the type of msft vendor event in the driver.
      
      But the purpose we reported mediatek event to the core layer is for the
      diagnostic purpose with that we are able to see the full packet trace via
      monitoring socket with btmon. Thus, it is harmless we keep the original
      type of mediatek vendor event here to avoid breaking the msft extension
      function especially they can be supported by Mediatek chipset like MT7921
      , MT7922 devices and future devices.
