Paul Walmsley 0e194d9da1 Documentation: riscv: add patch acceptance guidelines
Formalize, in kernel documentation, the patch acceptance policy for
arch/riscv.  In summary, it states that as maintainers, we plan to
only accept patches for new modules or extensions that have been
frozen or ratified by the RISC-V Foundation.

We've been following these guidelines for the past few months.  In the
meantime, we've received quite a bit of feedback that it would be
helpful to have these guidelines formally documented.

Based on a suggestion from Matthew Wilcox, we also add a link to this
file to Documentation/process/index.rst, to make this document easier
to find.  The format of this document has also been changed to align
to the format outlined in the maintainer entry profiles, in accordance
with comments from Jon Corbet and Dan Williams.

Kees Cook aa20485528 doc-rst: Programmatically render MAINTAINERS into ReST
In order to have the MAINTAINERS file visible in the rendered ReST
output, this makes some small changes to the existing MAINTAINERS file
to allow for better machine processing, and adds a new Sphinx directive
"maintainers-include" to perform the rendering.

Features include:
- Per-subsystem reference links: subsystem maintainer entries can be
  trivially linked to both internally and external. For example:
  https://www.kernel.org/doc/html/latest/process/maintainers.html#secure-computing

- Internally referenced .rst files are linked so they can be followed
  when browsing the resulting rendering. This allows, for example, the
  future addition of maintainer profiles to be automatically linked.

- Field name expansion: instead of the short fields (e.g. "M", "F",
  "K"), use the indicated inline "full names" for the fields (which are
  marked with "*"s in MAINTAINERS) so that a rendered subsystem entry
  is more human readable. Email lists are additionally comma-separated.
  For example:

    SECURE COMPUTING
	Mail:	  Kees Cook <keescook@chromium.org>
	Reviewer: Andy Lutomirski <luto@amacapital.net>,
		  Will Drewry <wad@chromium.org>

Thomas Gleixner ddaedbbece Documentation/process: Embargoed hardware security issues
To address the requirements of embargoed hardware issues, like Meltdown,
Spectre, L1TF etc. it is necessary to define and document a process for
handling embargoed hardware security issues.

Following the discussion at the maintainer summit 2018 in Edinburgh
(https://lwn.net/Articles/769417/) the volunteered people have worked
out a process and a Memorandum of Understanding.  The latter addresses
the fact that the Linux kernel community cannot sign NDAs for various
reasons.

The initial contact point for hardware security issues is different from
the regular kernel security contact to provide a known and neutral
interface for hardware vendors and researchers. The initial primary
contact team is proposed to be staffed by Linux Foundation Fellows, who
are not associated to a vendor or a distribution and are well connected
in the industry as a whole.

The process is designed with the experience of the past incidents in
mind and tries to address the remaining gaps, so future (hopefully rare)
incidents can be handled more efficiently.  It won't remove the fact,
that most of this has to be done behind closed doors, but it is set up
to avoid big bureaucratic hurdles for individual developers.

The process is solely for handling hardware security issues and cannot
be used for regular kernel (software only) security bugs.

This memo can help with hardware companies who, and I quote, "[my
manager] doesn't want to bet his job on the list keeping things secret."
This despite numerous leaks directly from that company over the years,
and none ever so far from the kernel security team.  Cognitive
dissidence seems to be a requirement to be a good manager.

To accelerate the adoption of this  process, we introduce the concept of
ambassadors in participating companies. The ambassadors are there to
guide people to comply with the process, but are not automatically
involved in the disclosure of a particular incident.

Linus Torvalds e468f5c06b The Compiler Attributes series
This is an effort to disentangle the include/linux/compiler*.h headers
 and bring them up to date.
 
 The main idea behind the series is to use feature checking macros
 (i.e. __has_attribute) instead of compiler version checks (e.g. GCC_VERSION),
 which are compiler-agnostic (so they can be shared, reducing the size
 of compiler-specific headers) and version-agnostic.
 
 Other related improvements have been performed in the headers as well,
 which on top of the use of __has_attribute it has amounted to a significant
 simplification of these headers (e.g. GCC_VERSION is now only guarding
 a few non-attribute macros).
 
 This series should also help the efforts to support compiling the kernel
 with clang and icc. A fair amount of documentation and comments have also
 been added, clarified or removed; and the headers are now more readable,
 which should help kernel developers in general.
 
 The series was triggered due to the move to gcc >= 4.6. In turn, this series
 has also triggered Sparse to gain the ability to recognize __has_attribute
 on its own.
 
 Finally, the __nonstring variable attribute series has been also applied
 on top; plus two related patches from Nick Desaulniers for unreachable()
 that came a bit afterwards.

Greg Kroah-Hartman 79dbeed36f Code of Conduct Interpretation: Add document explaining how the Code of Conduct is to be interpreted
The Contributor Covenant Code of Conduct is a general document meant to
provide a set of rules for almost any open source community.  Every
open-source community is unique and the Linux kernel is no exception.
Because of this, this document describes how we in the Linux kernel
community will interpret it.  We also do not expect this interpretation
to be static over time, and will adjust it as needed.

This document was created with the input and feedback of the TAB as well
as many current kernel maintainers.

The Code of Conflict is not achieving its implicit goal of fostering
civility and the spirit of 'be excellent to each other'.  Explicit
guidelines have demonstrated success in other projects and other areas
of the kernel.

Here is a Code of Conduct statement for the wider kernel.  It is based

From this point forward, we should abide by these rules in order to help

Markus Heiser 9799445af1 docs: tidy up TOCs and refs to license-rules.rst
The documentation and TOCs are organized in a manner of a tree. Adding a TOC to
the root, which refers to a file which is located in a subfolder forms a
grid. Those TOCs are a bit confusing and thats why we get additional error
messages while building partial documentation::

  $ make SPHINXDIRS=process htmldocs
  ...
  checking consistency... Documentation/process/license-rules.rst: \
  WARNING: document isn't included in any toctree

To fix it, the *root-license-TOC* is replaced by a reference and the
'license-roles.txt' is added to the Documentation/process/index.rst TOC.

BTW: there was an old licences remark in Documentation/process/howto.rst which

Konstantin Ryabitsev b72dde3869 Documentation/process: kernel maintainer PGP guide
This guide is an adapted version of the more general "Protecting Code
Integrity" guide written and maintained by The Linux Foundation IT for
use with open-source projects. It provides the oft-lacking guidance on
the following topics:

- how to properly protect one's PGP keys to minimize the risks of them
  being stolen and used maliciously to impersonate a kernel developer
- how to configure Git to properly use GnuPG
- when and how to use PGP with Git
- how to verify fellow Linux Kernel developer identities

I believe this document should live with the rest of the documentation
describing proper processes one should follow when participating in
kernel development. Placing it in a wiki on some place like kernel.org
would be insufficient for a number of reasons -- primarily, because only
a relatively small subset of maintainers have accounts on kernel.org,
but also because even those who do rarely remember that such wiki
exists. Keeping it with the rest of in-kernel docs should hopefully give
it more visibility, but also help keep it up-to-date as tools and
processes evolve.

Greg Kroah-Hartman 13277782dd Documentation: add Kernel Driver Statement to the kernel
Way back in 2008 we didn't have "robust" in-kernel documentation system,
so the idea of putting something like the kernel driver statement in the
kernel tree wasn't even imagined.  But now that has changed, so add the
old document to the kernel source itself to allow for us to properly
reference it in one canonical place (as the LF wiki keeps moving things
around.)

This also will allow people to add their names to it, as I seem to have
lost the ability to do that by not knowing how to edit things on the
original document.

Jonathan Corbet 9d2cccdd6c Merge branch 'doc-tweaks' into docs-next
The creation of the admin and process guides is a great thing, but, without
care, we risk replacing a messy docs directory with a few messy Sphinx
books.  In an attempt to head that off and show what I'm thinking, here's a
set of tweaks that, I think, make the existing Sphinx-formatted docs a bit
more accessible.
