That will complement existing CFLAGS_ and ASFLAGS_. As no one use it yet (I will use it, do not remove) - no need for convert-everything patch. Cc: Cyrill Gorcunov <gorcunov@openvz.org> Signed-off-by:

While this commit is logically part of the "implement cgns support" commit, it's worth noting this separately I think: since cgns requires each task to look at its own proc file, we can now no longer dump unprivileged tasks whose /proc doesn't belong to them. This is because unprivileged tasks can't mount /proc, so if their /proc doesn't belong to them and they need to read it (because they're in a cgns), the pie code can't do anything about it. For cgns, we could solve this problem by simply fork()ing and setns()ing to the tasks pid and cgroup namespaces, and then reading the /proc from that task instead. (And perhaps we should implement it that way so we can still dump tasks whose /proc doesn't belong to them, although I don't think that's a common case.) Signed-off-by:

cgroup namespaces are imminent to be merged into the kernel (indeed, they went into and out of 4.5 for minor issues), and will be carried as a patchset in the ubuntu 16.04 kernel. Here's an attempt at c/r. There are essentially three key steps: * on dump, in parse_task_cgroup, we should ask the task what cgroups it thinks it is in (unless it has the same cgroup ns id as its parent, then we should just take the prefixes from the parent's set), and set the prefix on the cg set * add a new restore step, prepare_cgroup_namespace(), which happens in prepare_task_cgroup() that does an unshare() if necessary * when restoring, in move_in_cgroup, if we're going to restore via usernsd, leave the full path. if not, use (cgset->path + len(cgset->cgns_prefix) as the path, since we will have already moved into the cgns_prefix and unshared. Another observation here is that we can support nesting, since these are restored heirarchically by nature. v2: * store cgns prefix length instead of full prefix in images * set has_cgroup_ns_id conditionally * drop unused argument to move_in_cgroup * add extra comments about what is happening when unsharing() on restore * add extra comments about what is happening when computing the actual cgns prefix Signed-off-by: -

Move static and transition into zdtm top. We can't move all the micro tests themselves, as we need to distinguish static from non static (zdtm.py makes additional checks on static ones). Signed-off-by: -

map is very good at generating rules. Just map gen function to array of it's parameters. Don't forget to eval the result. I'll use it in feature-tests generation and in someday coming compat 32-bit mode - in x86 makefiles. Cc: Cyrill Gorcunov <gorcunov@openvz.org> Signed-off-by:

This reverts commit a98014f3. As per Saied Kazemi, actually dump works without seccomp support from the kernel on non-seccomped tasks. The only problem was with criu check, but this would be addressed separately. Reverting the commit not to burden the API with (yet) unneeded stuff. Conflicts: lib/c/criu.h
