This is a proposed change to the way sockets are checkpointed. It makes the socket itself a proper objhash object, which can be checkpointed or restored as part of reading the stream (like many of the other first-class objects). Thus, we worry about checkpointing and restoring the socket-typed file, and read the related socket object(s) as a matter of course. By doing this, we are able to checkpoint sockets we find that aren't attached to descriptors. This is used in the final patch to make sure that a socket buffer's owner socket has been checkpointed, allowing us to use that socket to re-send the buffer on restore (thus retaining the source address). I've got a unit test for this that sets up three sockets, and loads some in-flight buffers before checkpoint, verifying that after checkpoint, recvfrom() sees them from the appropriate source socket. Does this approach seem reasonable? _______________________________________________ Containers mailing list Containers@xxxxxxxxxxxxxxxxxxxxxxxxxx https://lists.linux-foundation.org/mailman/listinfo/containers
