There is a buffer overflow in dscr_inherit_test.c test. In main(), strncpy()'s third argument is the length of the source, not the size of the destination buffer, which makes strncpy() behaves like strcpy(), causing a buffer overflow if argv[0] is bigger than LEN_MAX (100). This patch maps 'prog' to the argv[0] memory region, removing the static allocation and the LEN_MAX size restriction.

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.
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.
