This patch introduces a new subproject called "criu-coredump". The name is pretty much self-explanatory, it allows generating coredumps from criu images. Coredumps are readable and usable by gdb. The structure is something in the middle of kernel-generated and gdb-generated core dumps. This is a first iteration of core-dump patch series. It introduces ability to generate gdb-operatable core dump only for x86_64 machines. To support other architectures there will be a set to introduce proper structures for notes section of the core dump. It is also worth noting, that we still leave some notes(SIGINFO primarily) not fullfilled, as I still need to figure out what to put in there in our case, where no signal is involved in triggering core dump generation and other caveats like zeroed vvar(we have problems with it withing CRIU itself as well as gdb has some difficalties with it) and vsyscall vmas. One can already use produced core dump with gdb, there is also a quick simple demo https://asciinema.org/a/18936 .

CRIU (Checkpoint and Restore in Userspace)
An utility to checkpoint/restore tasks. Using this tool, you can freeze a running application (or part of it) and checkpoint it to a hard drive as a collection of files. You can then use the files to restore and run the application from the point it was frozen at. The distinctive feature of the CRIU project is that it is mainly implemented in user space.
The project home is at http://criu.org.
Pages worth starting with are:
- Kernel configuration, compilation, etc
- A simple example of usage
- More sophisticated example with graphical app
A video tour on basic CRIU features
