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.

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:

A tests is executed from different users in cases with and without userns, so it can't to open files which were created before. Here is an example for ns/user/static/inotify_irmap: 13355 mkdir("/etc", 0600) = -1 EEXIST (File exists) 13355 unlink("/etc/zdtm-test") = -1 EACCES (Permission denied) 13355 creat("/etc/zdtm-test", 0600) = -1 EACCES (Permission denied) Signed-off-by: -

For an established TCP connection, the send queue is restored in two steps: in step (1), we retransmit the data that was sent before but not yet acknowledged, and in step (2), we transmit the data that was never sent outside before. The TCP_REPAIR option is disabled before step (2) and re-enabled after step (2) (without this patch). If the amount of data to be sent in step (2) is large, the TCP_REPAIR flag on the socket can remain off for some time (O(milliseconds)). If a listen() is called on another socket bound to the same port during this time window, it fails. This is because -- turning TCP_REPAIR off clears the SO_REUSEADDR flag on the socket. This patch adds a mutex (reuseaddr_lock) per port number, so that a listen() on a port number does not happen while SO_REUSEADDR for another socket on the same port is off.
