Since the Linux RNG no longer uses sha1_transform(), the SHA-1 library is no longer needed unconditionally. Make it possible to build the Linux kernel without the SHA-1 library by putting it behind a kconfig option, and selecting this new option from the kconfig options that gate the remaining users: CRYPTO_SHA1 for crypto/sha1_generic.c, BPF for kernel/bpf/core.c, and IPV6 for net/ipv6/addrconf.c. Unfortunately, since BPF is selected by NET, for now this can only make a difference for kernels built without networking support.

README
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.
