  - atmclip修正 clip_push() 的無限遞回呼叫。 syzbot 報告了以下問題。 [0] 如果我們呼叫 ioctl(ATMARP_MKIP) 超過一次就會發生這個情況。在第一個呼叫期間clip_mkip() 會將 clip_push() 設定為 vcc->push()而第二個呼叫則將其複製到 clip_vcc->old_push()。稍後當通訊端為 close()dvcc_destroy_socket() 會將 NULL skb 傳送至 clip_push()進而呼叫 clip_vcc->old_push()進而觸發無限遞回。我們可以檢查 vcc->user_back (由第一個呼叫配置為 clip_vcc) 來防止第二個 ioctl(ATMARP_MKIP)。另請注意我們使用 lock_sock() 來防止爭用呼叫。 [0]
