hdrs: Fixup reinclusion preprocessor constants Make them look like __CR_<smth>_H__ with sed -e '1,2s/#\(ifndef\|define\) _\?_\?\(CR_\)\?/#\1 __CR_/' -e '1,2s/_H_\?_\?.*$/_H__/' on every header file. Signed-off-by: Pavel Emelyanov <xemul@parallels.com>

#include <sys/types.h>
crtools: link pstree_item-s in a tree (v3) because they describes a process TREE. It's usefull, when we dump tasks from another pid namespace, because a real pid is got from parasite. In previous version we need to update pid in two places one is in a pstree_item and one is in a children array. A process tree will be necessery to restore sid and pgid, because we should add fake tasks in a tree. For example if a sesion leader is absent. v2: fix rollback actions v3: fix comments from Pavel Emelyanov * add macros for_each_pstree_item * and a few bugs Signed-off-by: Andrey Vagin <avagin@openvz.org> Signed-off-by: Pavel Emelyanov <xemul@parallels.com>

images: Introduce the top-level file -- inventory Currently we store the images version in the core file. This is bad, since core file describes a single process (or thread) and says nothing about the images set as a whole (let alone the fact that it's being parsed too late). Thus introduce the inventory image file which describes the image set the way we need (want). For now the only entry in it is the images version. In the future it can be extended.

int cr_dump_tasks(pid_t pid);
dump: Introduce the pre-dump action With this action criu will seize tasks, grab all its memory into page-pipes, rest dirty tracker and will then release them. Writing the memory from page-pipes would occur after tasks are unfreezed and thus the frozen time should become reasonably small. When pre-dump is in action, the dirty tracking is forcedly turned off as well as tasks are resumed afterwards, not killed, by default. This is a prerequisite for iterative migration.

bool may_restore(struct _CredsEntry *);
security: Introduce (rather basic) security restrictions for C/R Right now we have an ability to launch the C/R service from root and execure dump requests from unpriviledged users. Not to be bad guys, we deny dumping tasks belonging to user, that cannot be "watched" (traced, read /proc, etc.) by the dumper. In the future we will use this "engine" when launched with suid bit, and (probably) will have more sophisticated policy. Signed-off-by: Pavel Emelyanov <xemul@parallels.com>
