Commits on Sep 9, 2021

  1. libcontainer: add support for Landlock 

    This patch introduces Landlock Linux Security Module (LSM) support in
runc, which was landed in Linux kernel 5.13.

This allows unprivileged processes to create safe security sandboxes
that can securely restrict the ambient rights (e.g. global filesystem
access) for themselves.

runtime-spec: opencontainers/runtime-spec#1111

Fixes opencontainers#2859
