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

Andrew Lunn says: ==================== mv88e6xxx Watchdog support The Marvell switches have an in built watchdog over some of the internal state machine. The watchdog can be configured to raise an interrupt on error. The problem the watchdog found is then logged to the kernel log. The older switches can automagically perform a software reset when the watchdog triggers. This just resets the internal state machine, but leaves the switch configuration unchanged. The 6390 family of switches cannot both raise an interrupt and automagically perform a software reset. So the interrupt handler has to perform the switch reset, and then re-enable the watchdog interrupts. This has been tested using hacked together debugfs code which allows the "force" bit to be set, so cause a watchdog interrupt. v2: Remove g2_prefix ==================== Signed-off-by: David S.

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.
