As an API for dumping and restoring the data the structure with __u32-s is used. Getting one (and restoring) also involve the size of the structure so that both -- caller and library -- can know which "version" of it the other one is using. As a starting point all the fields that tcp_entry carries are used. Also note, that only tcp connection info is handled by the library. Stuff like addresses and ports, socket options and other are left for the caller to care for. Signed-off-by: Pavel Emelyanov <xemul@virtuozzo.com>
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
