I recently had a discussion in a container-selinux issue on why we allow certain capabilities by default for containers. The conversation is around DAC_OVERRIDE, a Linux capability which allows privileged processes, usually root, to ignore ownership and read/write permissions Discretionary Access Control (DAC). “As @wrabcak notes in Why do you see DAC_OVERRIDE SELinux denials?, In…
