Rename prep_cr_fdset_for_dump into cr_fdset_open and make it reentable, i.e. every next enter will open more files in the same fdset. Required for zombies and makes the code cleaner. Signed-off-by:

It's not needed anymore, it was handing cases where no fork-with-pid functionality were in kernel, but now it's simply unneeded. Also drop redundant getpid() calls. Passes all tests (except fork test which known to fail). Signed-off-by:

I haven't found anything similar in there. It currently just fails most of the launches because seize doesn't work with zombies, but I'm working on it... However, when it manages to miss the zombie it triggers the problem with freezer (fixed by previous patch). Signed-off-by:

We can do it since we may not want to dump the missed sockets. But later, when we will start dumping containers, we'll better fail here, rather than in the dump stage. Signed-off-by:

Handle SIGCHLD and if someone failed, nr_in_progress is set to -1. If crtools notices that nr_in_progress is negative, it kills all tasks. v2: * Use named constants for task_entries->start in restorer.c * Use SA_NOCLDWAIT when setting sigchild handler, this makes sigchild handler simpler.

This is a precursor patch. Netlink request code is mostly the same for any kind of sockets. Only 2 places differs: request creation and callback address. This patch parametrizes netlink call function with a pointer to a request structure, request size and receive callback, which replaces hard-coded unix sockets parts. Signed-off-by:
