Check that files opened before switching to new mount namespace remain in it after restore. Right now this is not so :( Andrey is fixing the issue. Christopher, can you check whether the ns_child's call to system() works in your minimal set-ups (it launches cat and awk). If not, then I should rewrite this routine in pure C. The first version was written by Pavel (xemul@). v2: don't use test_init_ns don't call awk and cat Signed-off-by: -

Here is a problem with ghost files. Links are created on restore, but they can't be created on any mount point, because a mount point can be non-root bind-mount of another one. So we need to find the root mount and create all links there. v2: clean up v3: add optimization for the case when both links on the same mount point. v4: don't look up mount points by mnt_id in a second time.

On restore we add a temporary root to a mount point path. It's convinient for restoring mount namespaces, but real paths are used for restoring link-remap files. v2: replace the offset field on a char * field Signed-off-by:

The m->bind will be used to get the "lowest" mount. A mount is called "lowest" in the chain of bind-mounts when its m->bind is NULL. I.e. -- it's the mount of the root dir of an FS, all the others are bind-mounted from it. The propagate_siblings() is called for each new mount and sets the bind field for others. A part of these other mounts can be already mounted. Signed-off-by:

This modifies the x86 VDSO code to work on AArch64. Signed-off-by:

Christopher Covington authored
While it duplicates hundreds of lines of code, this is the short term strategy Cyrill and I have agreed to for supporting VDSOs across multiple architectures [1]. With better understanding of where things differ per-architecture, or even improved consolidation in the kernel, we can hopefully move to a more shared implementation in the future. 1. http://lists.openvz.org/pipermail/criu/2014-August/015218.htmlAcked-by:

As it was reported, some systems don't use /etc/passwd. On such systems getpwuid fails with undefined errno(see getpwuid(3)) not allowing criu to restrict ids with user additional groups. Luckily, on such systems criu is run as root, so we can just skip obtaining additional groups, as they don't matter for root. Reported-by:

Currently check_ids is used to check uids only. So lets rename it and drop crid argument, as we can use cr_uid directly. Signed-off-by:

Currently, we only check if process gids match primary gid of user. But process and user have additional groups too. So lets: 1) check that process rgid,egid and sgid are in the user's grouplist. 2) on restore check that user has all groups from the images. Signed-off-by: -

For that mnt namespaces should be dumped after files. v2: rework enumeration of namespaces in dump_mnt_namespaces() Signed-off-by:
-
Andrey Vagin authored
Currently collect_shared is executed for each mount namespace separately, so we miss the dependencies between namespaces. For example, we have two namespaces, the first one contains a tmpfs mount and the second one contains a non-root bind-mount of this tmpfs. Without this patch this example can't be dumped. On restore mnt_build_tree() is called for all namespaces at once, thus this bug doesn't exist there. Signed-off-by:
