Currently on dump we generate too many image files, effectively all the stuff from the GLOB set is created. The thing is that sometimes some of created images can be empty (just contain the magic number at the head). Thos images are useless and just waste the space. When applied after the "empty images" set, this introduces the lazy images -- when we call open_image() the actual file is only created (and the magic number is written into it) when the very first object goes into it. For example for the simplest test we have, then static/env00 one, the created image files are core-7290.img creds-7290.img fdinfo-2.img fs-7290.img ids-7290.img inventory.img mm-7290.img pagemap-7290.img pages-1.img pstree.img reg-files.img sigacts-7290.img Signed-off-by:Pavel Emelyanov <xemul@parallels.com>

When an image of a certian type is not found, CRIU sometimes fails, sometimes ignores this fact. I propose to ignore this fact always and treat absent images and those containing no objects inside (i.e. -- empty). If the latter code flow will _need_ objects, then criu will fail later. Why object will be explicitly required? For example, due to restoring code reading the image with pb_read_one, w/o the _eof suffix thus required the object to be in the image. Another example is objects dependencies. E.g. fdinfo objects require various files objects. So missing image files will result in non-resolved searches later. Signed-off-by: -

When page-read fails to open the pagemap image it reports error. One place (stacked page-reads) need to handle the absent images case gracefully, so fix the return codes to make this check work. Signed-off-by: -

Current code doesn't make any difference between OPT and no-OPT except for the message is printed or not in the open_image(). So this particular change changes nothing but the availability of this message. In the next patches I wil introduce "empty images" to deal with the ENOENT situation in a more graceful manner.

This one gets index from fd/fd_parms pair on dump. For console and vt the index is constant and just sits on the tty_type (will also be used on restore, see next patch). Signed-off-by: -

The plan is to replace tons of if (type == TTY_TYPE_FOO) checks with type->something dereferences. To do this, start with replacing int type with struct tty_type * in relevant places and fixing compilation. Signed-off-by: -

Here it is. The major new thing I think is the CRIT tool that will be the main one to mainupulate images and will eventually replace the "criu show" action. Signed-off-by:

/dev/tty stands for current terminal which we don't yet implemented a support for. This is a bugfix for upcoming stable version, the proper support of /dev/tty is gonna be implemented separately. Reported-by:
