security: Yama LSM This adds the Yama Linux Security Module to collect DAC security improvements (specifically just ptrace restrictions for now) that have existed in various forms over the years and have been carried outside the mainline kernel by other Linux distributions like Openwall and grsecurity.

This selects Yama, which extends DAC support with additional
system-wide security settings beyond regular Linux discretionary
access controls. Currently available is ptrace scope restriction.
Yama: remove needless CONFIG_SECURITY_YAMA_STACKED Now that minor LSMs can cleanly stack with major LSMs, remove the unneeded config for Yama to be made to explicitly stack. Just selecting the main Yama CONFIG will allow it to work, regardless of the major LSM. Since distros using Yama are already forcing it to stack, this is effectively a no-op change. Additionally add MAINTAINERS entry. Signed-off-by: Kees Cook <keescook@chromium.org> Signed-off-by: James Morris <james.l.morris@oracle.com>
