CRIU can checkpoint/restore a trivial hello_word process to running Linux containers. However, with the current implementation of CRIU, it can't checkpoint/restore a process that has a memfd_secret file descriptor(s) opened. So, the purpose of the proposed project is to add new functionality to successfully checkpoint/restore any process that has memfd_secret file descriptor(s) opened.
