commit 641114d2af312d39ca9bbc2369d18a5823da51c6 upstream. gcc 9 now does allocation size tracking and thinks that passing the member of a union and then accessing beyond that member's bounds is an overflow. Instead of using the union member, use the entire union with a cast to get to the sockaddr. gcc will now know that the memory extends the full size of the union.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
