[CRIU] criu-dev restore forked process

[Connor Zanin]

Hi all,

This question is based on
commit 7b27c4d4b254fd1bdb11ee74808be2786c785b53 which is in the criu-dev
branch.

The commands used are:

sudo ./criu dump -t <pid> -j -D <directory>
and
sudo ./criu restore -j -D <directory>

The code used, as well as the checkpoint directory and log files are
attached.

CRIU is unable to restore the process tree, seemingly because it cannot
find the session leader for the child process. Is this normal behavior?
Should I be supplying another option? Or, is this a bug?

It seems to be a bug creating the shell session in the process tree
(prepare_pstree_for_shell_job()).

Thanks for any help!

Cheers,
