[PATCH OLK-5.10] Bluetooth: MGMT: Fix deadlock in mgmt_pending_lock
by Wang Tao 13 Dec '25

13 Dec '25

hulk inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/IDCRDT -------------------------------- In the following scenarios: When the task executes mgmt_device_disconnected, it holds the mgmt_pending_lock; during the traversal of pending events for processing, disconnect_rsp is executed, which attempts to acquire the mgmt_pending_lock again, this results in a deadlock. mgmt_device_disconnected mgmt_pending_foreach(MGMT_OP_DISCONNECT, hdev, true, disconnect_rsp, &sk) mutex_lock(&hdev->mgmt_pending_lock) list_for_each_entry_safe(cmd, tmp, &hdev->mgmt_pending, list) cb(cmd, data) // disconnect_rsp mutex_unlock(&hdev->mgmt_pending_lock) disconnect_rsp mgmt_pending_remove mutex_lock(&cmd->hdev->mgmt_pending_lock) In the mainline commit 6fe26f694c82 ("Bluetooth: MGMT: Protect mgmt_pending list with its own lock"), the same functionality as the mgmt_pending_remove function has already been added to the mgmt_pending_foreach function. Therefore, mgmt_pending_remove is removed from the disconnect_rsp function, thereby avoiding the deadlock issue.
