Revision ff1fa2081d173b01cebe2fbf0a2d0f1cee9ce4b5 authored by Jakub Kicinski on 29 June 2022, 18:19:10 UTC, committed by Jakub Kicinski on 30 June 2022, 18:34:10 UTC
Eric reports that syzbot made short work out of my speculative fix. Indeed when queue gets detached its tfile->tun remains, so we would try to stop NAPI twice with a detach(), close() sequence. Alternative fix would be to move tun_napi_disable() to tun_detach_all() and let the NAPI run after the queue has been detached.
