Hi Santosh, What is that fix? You forgot to provide any link/reference. I also don't see any patches from you at around that date...Fix [1] was later not added since there was a still a race. Wanted to see if the issue re-appears after recent netns fix [2].We will not see if the bug re-appears or not until this bug is closed. Please see this recent discussion about another rds bug: https://groups.google.com/d/msg/syzkaller-bugs/3XjmOzr5jRU/g7pXIsY1BgAJ In the current state syzbot will never report bugs in these functions again.OK. Can you close that one then in that case ?
Anybody can do this: #syz fix: rds: tcp: use rds_destroy_pending() to synchronize netns/module teardown and rds connection/workq management syzbot provides full self-service, see first email and in particular this: https://github.com/google/syzkaller/blob/master/docs/syzbot.md#communication-with-syzbot Thanks
