Jakub Sitnicki says: ==================== This patch set addresses the syzbot report in [1]. Patch #1 has been suggested by Eric [2]. I extended it to cover the rest of sock_map proto callbacks. Otherwise we would still overflow the stack. Patch #2 contains the actual fix and bug analysis. Patches #3 & #4 add coverage to selftests to trigger the bug.

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.
