Consider the case where --freeze-cgroup=/lxc/foo, but (e.g. with systemd in lxc), all of the tasks actually live in a set of sub cgroups, e.g. /lxc/foo/init.scope and others. In this case, we will have a multi-headed controller, since there is nothing in the common parent. We should just save the freezer value in all of these heads instead of failing. Note that this doesn't address the larger problem that only the top level freezer.state file is c/r'd, or waht happens when the container itself has frozen tasks but not at the top level. After some discussion, there is no nice way to atomically test-and-set the cgroup freezer, so we'll need some other kernel help. But I'll ignore this for now :) Signed-off-by:

As with the socket diag modules, since we might be using the ip*filter_tables modules, we should preload those as well, in case the host system hasn't already loaded them. Really, I should implement netlink buffer dumping so we can get rid of this hack :) v2: remember to close /dev/null fd after using it Signed-off-by:

We can do this, but we need to be sure that all structures are consistent in any moment and we need to block alarm when they are inconsistent. I don't think that we really want to do this now. I suggest to interrupt a current syscall if an alarm signal is triggered. v2: print an error message before exiting Cc: Andrey Ryabinin <aryabinin@virtuozzo.com> Signed-off-by:

The problem with --no-print-directory set by default is when we run :make from vim and compilation performed by a sub-make fails, vim can't figure out the correct path to a file with error, so instead of jumping to the position of the first error, it opens a new empty file. When make prints "Entering directory ..." and "Leaving directory ..." messages, vim :make works as intended. [Alternatively, we could add -w to $(MAKE) invocations where needed, but the problem is --no-print-directory overrides -w even if -w comes later in the options list, so -w is not working. I was also thinking about detecting whether we are running from vim, but when we'll need to add detection for emacs etc., so let's keep things simple.] Cc: Andrey Vagin <avagin@openvz.org> Cc: Cyrill Gorcunov <gorcunov@openvz.org> Signed-off-by:

With GNU make, using .PHONY leads to the same result as using the "FORCE" hack, but unlike FORCE is not a hack. Since we do not plan to use any other make implementation than GNU make, let's not provide FORCE in nmk. For more details about why PHONY is better than FORCE, see http://www.gnu.org/software/make/manual/make.html#index-FORCESigned-off-by:

When link criu we make sure that all underlied systems are up to day: images, syscalls, pie part. Thus provide own targets for them and link on a final pass. This should fix the problem when some file in images|syscalls|pie are changed but criu itself is not rebuilt and relinked. NB: Need to revisit the config/version/feature-test generations too.

Everytime we build the executable we've to check all the deps and sources for changes, thus don't protvide criu/criu on toplevel as a target file (my bug in 496b51b6). Instead bring this target as a phony back but drop phony from criu/Makefile itself, as it should be from the beginning. Same time remove unneeded phonies over the targets which are real files.
