Description:
The desire for the ability to checkpoint a process to record its state in
a form that can be restarted at a future time on Linux is almost as old as Linux itself. See, for example, this announcement of a checkpoint
project that appeared in LWN in 1998. While working solutions exist, they
can be somewhat fragile and difficult to use; it is not surprising that
some people are interested in finding a better alternative. A current
effort goes by the name CRIB,
for Checkpoint/Restore in (naturally) BPF. It is far from clear that CRIB
will replace the existing solutions, but it is an interesting look at a different way of solving the problem.
