Description

When we were introducing dmz to runc, we have realized that there were 3 reasons we should disable runc-dmz:

  1. runc-dmz does not play well with selinux #4057, fixed by #4053.
  2. The container process has a CAP_SYS_PTRACE ability, fixed by #3987.
  3. If the container process is not root and the capabilities are not in the ambient set #4125, will be fixed by #4137.

Maybe there are some more scenarios that can't use runc-dmz, please provide to help us improve or deprecate it. Thanks.

Research direction

Start by reviewing the linked issues #4057 and #4125 and their fixes (#4053, #3987, and #4137), then inspect the runc-dmz behavior involved in SELinux, CAP_SYS_PTRACE, and ambient capabilities. Done means documenting any additional scenarios that fail, or producing a clear proposal to improve or deprecate runc-dmz.
