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.

Now we have only one mutex nr_in_progress, it says how many tasks are not restored yet. A negative value signs that someone failed. Signed-off-by:

This test is based on socket_aio. It's actually the same, except that socket binding and listening is done before checkpointing and connection to socket is done after migration. Signed-off-by:

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:

Objects does not depend on dep files. Dep files provide rules to build object files. Thus we need to include dep files. This also leads make to rebuild dep files (if required) before an other targets. Signed-off-by:

Before this patch the restorer's code is linked in crtools and then we copied functions from it. In this case all function should be inline and we can't use a global variables. I suggest to make it like parasite. The restorer's code is isolated in own file and will be copied wholly. The restorer's code is compiled as position-independent code, so we can use functions and global variale (E.g. to save descriptor for log messages). v2: correct indentions in a separate patch v3: introduce a variable restore_task_exec_start symmetrical to restore_thread_exec_start v4: don't give command in restorer_thread() Signed-off-by: -

BUG_ON_HANDLER from util.h may be used in restorer. E.g. #include <util.h> #include <lock.h> Now the process will be segfaulted and you can find a line number in assemgler code. We will print messages a bit late. Signed-off-by: -

This patch prepares code to handle errors. In the near future we will handle SIGCHLD. If a restore of one task fails, we will send a signal to other for completing. For this we should have ability to wait until all task wills be restored. This patch does it. v2: Don't wait children. Signed-off-by:

Sometime we want to have a shared mapping in restorer. E.g. A storage for shared memory entries. This entries contains locks, which should be released in restorer. v2: fixed according to Pavel's comments Signed-off-by:
