[ Upstream commitf04a32b2c5] The sign-file utility (from scripts/) is used in prog_tests/verify_pkcs7_sig.c, but the utility should not be called as a test. Executing this utility produces the following error: selftests: /linux/tools/testing/selftests/bpf: urandom_read ok 16 selftests: /linux/tools/testing/selftests/bpf: urandom_read selftests: /linux/tools/testing/selftests/bpf: sign-file not ok 17 selftests: /linux/tools/testing/selftests/bpf: sign-file # exit=2 Also, urandom_read is mistakenly used as a test. It does not lead to an error, but should be moved over to TEST_GEN_FILES as well. The empty TEST_CUSTOM_PROGS can then be removed.

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.
