Minimal supplement to upstream Kernel Self Protection Project changes. Features already provided by SELinux + Yama and archs other than multiarch arm64 / x86_64 aren't in scope. Only tags have stable history. Shared IRC channel with KSPP: irc.libera.chat #linux-hardening

512b sectors vs device's physical sectorsize was not maintained consistently and as such the support for >512b sector devices has bugs. The log metadata expects native sectorsize but 512b sectors were being stored. Also, device's sectorsize was assumed when assigning the bi_sector for blocks that were being logged. Fix this up by adding two helpers to convert between bio and dev sectors, and use these in the appropriate places to fix the problem and make it clear which units go where. Doing so allows dm-log-writes use with 4k devices. Signed-off-by: Josef Bacik <jbacik@fb.com> Signed-off-by: Mike Snitzer <snitzer@redhat.com> |

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. 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.
