Björn Töpel says: ==================== William found two bugs, when doing socket teardown within the same process. The first issue was an invalid munmap call, and the second one was an invalid XSKMAP cleanup. Both resulted in that the process kept references to the socket, which was not correctly cleaned up. When a new socket was created, the bind() call would fail, since the old socket was still lingering, refusing to give up the queue on the netdev. More details can be found in the individual commits.

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.
