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:

"%m" can't be used to print strerror(errno), because print_on_level() calls gettimeofday() which can overwrite errno. For example: 13486 connect(4, {sa_family=AF_INET, sin_port=htons(8880), sin_addr=inet_addr("127.0.0.1")}, 16) = -1 ENETUNREACH (Network is unreachable) 13486 gettimeofday({1423756664, 717423}, NULL) = 0 13486 open("/etc/localtime", O_RDONLY|O_CLOEXEC) = -1 EACCES (Permission denied) 13486 write(2, "15:57:44.717: 4: ERR: socket_udp.c:73: Can't connect (errno = 101 (Permission denied))\n", 91) = 91 Signed-off-by: -

We link files to each other at restore time to restore unlinked paths. Kernel has strange secutiry restrictions about linkat we use. If the fsuid of the caller doesn't equals the uid of the file and the file is not "safe" one, then only global CAP_CHOWN will be allowed to link(). This brings problems in user namespaces -- uns root is not allowed to linkat any file, unlike global root. Fortunately, we can change the fsuid temporarily and still linkat the file we want. Hopefully this hack will go away some day soon, when the kernel will have saner checks for linkat capabilities. Signed-off-by:
