Lets simulate some errors and check what error will be returned by service. v2, fix tests accordingly to new errorlist v3, fix tests accordingly to new errorlist, again Signed-off-by:

/dev/ttyN are the virtual terminals which are provided by the system with major 4 and minor 1..63. You can run some program on ttyN by pressing alt+ctrl+FN and running it manualy or by using open(openvt nowadays). This patch also allows us to run all our tests from a vt. v2, style fix + using linux/vt.h for constants Signed-off-by:

Currently zdtm doesn't set additional groups when running tests. It sets uids and gids to some non-root values, but additional groups remain untouched, which allows tests to inherit groups list, which leads to different behaviour depending on a way you run tests. Signed-off-by:

This is a very common error when using criu. The problem here is that we need to somehow transfer cr_errno from one process to another. I suggest using pipe to give one end to children and read cr_errno on other after restore is finished. v2, Pavel suggested putting errno into shared task_entries. v3. and he also suggested using cmpxchg Signed-off-by:

In case if we're migrating to another node where @total_sleep_time has a big value we might fail here because we don't support tracking of @total_sleep_time at all, neither we can somehow restore it without kernel patching (and it's hardly if ever be allowed in vanilla kernel). Thus simply remember @total_sleep_time value before and after c/r stage removing it from the computations. Signed-off-by:

There are cases where a process's file descriptor cannot be restored from the checkpoint images. For example, a pipe file descriptor with one end in the checkpointed process and the other end in a separate process (that was not part of the checkpointed process tree) cannot be restored because after checkpoint the pipe will be broken. There are also cases where the user wants to use a new file during restore instead of the original file at checkpoint time. For example, the user wants to change the log file of a process from /path/to/oldlog to /path/to/newlog. In these cases, criu's caller should set up a new file descriptor to be inherited by the restored process and specify the file descriptor with the --inherit-fd command line option. The argument of --inherit-fd has the format fd[%d]:%s, where %d tells criu which of its own file descriptors to use for restoring the file identified by %s. As a debugging aid, if the argument has the format debug[%d]:%s, it tells criu to write out the string after colon to the file descriptor %d. This can be used, for example, as an easy way to leave a "restore marker" in the output stream of the process. It's important to note that inherit fd support breaks applications that depend on the state of the file descriptor being inherited. So, consider inherit fd only for specific use cases that you know for sure won't break the application. For examples please visit http://criu.org/Category:HOWTO. v2: Added a check in send_fd_to_self() to avoid closing an inherit fd. Also, as an extra measure of caution, added checks in the inherit fd look up functions to make sure that the inherit fd hasn't been reused. The patch also includes minor cosmetic changes.

We may close the master before reading the slave if the child runs first when the parent wakes it up using task_waiter_complete. In this case the subsequent read from the slave will return 0 resulting in a false positive test failure: 13:23:42.194: 30914: ERR: pty02.c:89: read(slave) failed (errno = 11 (Resource temporarily unavailable)) Fix this by waking the child, which closes the master, only after the read has been completed. Also note errno = EAGAIN in the failure report above, which looks really confusing. Let's print the actual number of bytes read/written along with the errno while reporting a read/write failure to make the error reporting clearer in this test. Signed-off-by:

maps007 segfaults on i386, because "size" is calculated bigger than allowed. This occurs when the result of lrand48() * PAGE_SIZE is negative. In this case the % operation returns a negative value too, what is unexpected. Signed-off-by:

So, according to the recently accepted plan we have 1.4. Biggest achievement here is that we've finally started with user namespaces, fixed CRIU to work smoothly with the p.haul project and optimized images and /proc files IO. And a bunch of bugs, of course. Signed-off-by:
