Description
In the Linux kernel, the following vulnerability has been resolved:
rtnetlink: make sure to refresh master_dev/m_ops in __rtnl_newlink()
While looking at one unrelated syzbot bug, I found the replay logic
in __rtnl_newlink() to potentially trigger use-after-free.
It is better to clear master_dev and m_ops inside the loop,
in case we have to replay it.
