Dump the core-pid.img file only. On restore select the way of killing task based on his exit_code -- exit or kill with a signal. Before dying unblock all the handlers and set SIG_DFL to it (to make the dead signal other than KILL be deliverable). Signed-off-by:

The absent image file on shared resources preparation now means -- no resources for this pid (zombies will not have these files). This is not the most elegant solution, but I don't have anything better in mind. Need to think over, all the more so we're most likely about to reimplement the way image is stored some day in the future. Signed-off-by:

Introduce 3 states we will have to work with: * alive for tasks sleeping or running * dead for zombies * stopped for stopped tasks. We cannot distinguish tasks in this state now, but with freezer cgroup this will become possible Signed-off-by:

Kill all the macros for reading/writing image parts. New API looks like * write_img_buf/write_img Write an object into an image. Reports 0 for OK, -1 for error. The _buf version accepts object size as an argument, the other one uses sizeof() * read_img_buf/read_img Reads an object from image. Reports 0 for OK, -1 for error or EOF. * read_img_buf_eof/read_img Reads an object from image. Reports 1 for OK, 0 for EOF and -1 for error. This is not symmetrical with the previous one, but it was done deliberately to make it possible to write code like ret = read_img_bug_eof(); if (ret <= 0) return ret; /* 0 means OK, all is done, -1 means error was met */. ... /* 1 means object was read, can proceed */ Signed-off-by:

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.
