Doc Text:
.`criu` rebased to version 3.5 Red Hat Enterprise Linux 7.2 introduced the `criu` tool as a Technology Preview. This tool implements *Checkpoint/Restore in User-space (CRIU)*, which can be used to freeze a running application and store it as a collection of files. Later, the application can be restored from its frozen state. Note that the `criu` tool depends on `Protocol Buffers`, a language-neutral, platform-neutral extensible mechanism for serializing structured data. The `protobuf` and `protobuf-c` packages, which provide this dependency, were also introduced in Red Hat Enterprise Linux 7.2 as a Technology Preview. In Red Hat Enterprise Linux 7.6, the `criu` packages were upgraded to upstream version 3.9, which provides a number of bug fixes and optimization for the *runC* container runtime. In addition, support for the 64-bit ARM architectures and the little-endian variant of IBM Power Systems CPU architectures has been fixed.

Description Adrian Reber 2016-11-30 17:30:45 UTC
As long as criu is a technology preview we should try to follow upstream. Upstream is still fast moving and is still implementing important features.

Hi Marie,

sorry for forgetting about this.

criu has been upgrade from 2.3 in RHEL 7.3  to 2.12 RHEL 7.4. As long as it is still a technology preview we are taking whatever version upstream releases.

Most important changes, hmm, a lot has changed. One thing is that additional states of TCP sockets are supported. Not only listening and established sockets can be restored, but also half-closed sockets. mac-vlan devices are supported. Memory changes tracking for anonymous shared memory.

There is also another documentation effort ongoing for another criu related feature:

Although it is not yet totally clear what will be part of RHEL 7.4
