I copied __ptr_oob* checks from util-vdso.c. That will allow to check not only structure begin pointers, but structure end also. Before this patch code checked if strings section's header pointer is OOB, but it did it after dereferencing this pointer, which is meaningless. Now it checks: - OOB of sections table, - strings section's header should be inside sections table, - check strings section with it's length for OOB. In the very next patches I will add tests for this functions and other compel-related changes.

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
