This is a precursor patch for AutoFS mount restore. To restore AutoFS indirect mount points, we have to create mount point dentries. This can do only the process with pgrp, configured to mount. Process, which does AutoFS mount call (init) at that moment is not. Restoring actual pgrp before sid breaks sid restoring. Thus, restoring of sid is required to make process group leader.

In the most cases, file descriptor is not need in this function. It's need in the case of creating a regular file only. So we can use chown() instead of fchown(), and operate with a path directly. The patch moves copying content of a regular file to new function mkreg_ghost(). This will be used in next patches. Also, parameter gf will be used. Signed-off-by:

Although we don't want to restore the values on these files, we definitely do want to restore the permissions, as certain container engines (lxc) make use of this. Signed-off-by:

The root mount is always external and master_id is external too. It's required to validate mounts. We already do this on restore, but we need to do this on dump too. Otherwise we will get the error: Mount %d %s (master_id: %d shared_id: %d) has unreachable sharing. Try --enable-external-masters. https://jira.sw.ru/browse/PSBM-43260Signed-off-by:

If for some reason ptrace_poke_area return error we might left dumpee with memfd descriptor opened. Later in code we remove out injected blob making dumpee to look untouched but descriptor will hang there. lsof from container output: | systemd-u 48 root 6u REG 0,4 0 53855 /memfd:CRIUMFD (deleted) Thus lets close it immediately. https://jira.sw.ru/browse/PSBM-43199Signed-off-by:

criu detaches from tasks in freezer_detach() in this case Signed-off-by:

Andrew Vagin authored
We need to detach from all processes before waiting the root task, because one of these processes may collect processes from a target pid namespace. The pid namespace is destroyed only when all processes have been killed and collected. https://jira.sw.ru/browse/PSBM-43089Signed-off-by:

This test calls iptables to set a new packet filter using a shared library libxt_standard.so. Unfortunately, depending on the distribution we are running on, this shared library may be stored on a different place. This patch allows this test to be run on Debian like systems. Signed-off-by:

Laurent Dufour authored
Depending on the distribution, binaries or shared libraries a test is dependent of may not be stored at the same place. This patch introduces the ability to define option in the dependency list, by separating the optional target names by a '|' character. For instance the dependency of test may be described this way: {'flavor': 'ns', 'deps': [ '/bin/foo|/usr/bin/foo' ], 'flags': 'suid'} Note, there shouldn't be any spaces around the '|'. If none of the optional dependency is satisfied, an error is raised. Signed-off-by: -

The descriptor for test netns-nf and netns are referencing /bin/diff. On Fedora this is a hard link to /usr/bin/diff created during the install of the package diffutils. However this hard link doesn't exist on Debian like systems. Referencing /usr/bin/diff works in both cases. Signed-off-by:

It turns out we can't just test for /proc/<pid>, because the kernel appends (deleted), since the directory is actually deleted (vs. something like /proc/1/mountinfo, where the file still exists in the unlinked directory, so there is no (deleted)). See comment for details. v2: s/ret/is_dead in /proc/<pid>/xxx test, split tests to correctly test both cases Signed-off-by:
