Documentation/process: Embargoed hardware security issues

2019-08-28T20:36:07Z

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.

Makefile: Globally enable fall-through warning

2019-07-26T01:13:54Z

Now that all the fall-through warnings have been addressed in the kernel, enable the fall-through warning globally. Also, update the deprecated.rst file to include implicit fall-through as 'deprecated' so people can be pointed to a single location for justification.
