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:Pavel Emelyanov <xemul@parallels.com>

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. Thanks to Amey Deshpande <ameyd@google.com> for debugging. Signed-off-by:
