Dapper - Cross-ISA Process Snapshot Rewriting #

Dapper transforms a live process’s state for different purposes. For example, Dapper supports live process migration of natively compiled Linux binaries across servers with CPUs of different architectures. It also supports re-randomizing the stack and registers of a process to improve security.

dapper-overview

Dapper was built on top of CRIU to dump a running process and then transform the CRIU images to support restoration on servers of a different architecture. Currently, Dapper supports process migration on x86-64 and aarch64 CPUs.You can find more information about Dapper in the following paper:

Dapper’s code is available on our GitHub as open-source software. You can also find a Demo of how Dapper works.
