There is a strange unlocked read of the ID state when checking for reuseaddr. This is because an ID cannot be reusable once it becomes a listening ID. Instead of using the state to exclude reuse, just clear it as part of rdma_listen()'s flow to convert reusable into not reusable. Once a ID goes to listen there is no way back out, and the only use of reusable is on the bind_list check. Finally, update the checks under handler_mutex to use READ_ONCE and audit that once RDMA_CM_LISTEN is observed in a req callback it is stable under the handler_mutex.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
