Rename all the virCgroupForXXX methods to use the form virCgroupNewXXX since they are all constructors. Also make sure the output parameter is the last one in the list, and annotate all pointers as non-null. Fix up all callers, and make sure they use true/false not 0/1 for the boolean parameters Signed-off-by: NDaniel P. Berrange <berrange@redhat.com>

The virCgroupMounted method is badly named, since a controller can be mounted, but disabled in the current object. Rename the method to be virCgroupHasController. Also make it tolerant to a NULL virCgroupPtr and out-of-range controller index, to avoid duplication of these checks in all callers Signed-off-by: NDaniel P. Berrange <berrange@redhat.com>

Currently when getting an instance of virCgroupPtr we will create the path in all cgroup controllers. Only at the virt driver layer are we attempting to filter controllers. This is bad because the mere act of creating the dirs in the controllers can have a functional impact on the kernel, particularly for performance. Update the virCgroupForDriver() method to accept a bitmask of controllers to use. Only create dirs in the controllers that are requested. When creating cgroups for domains, respect the active controller list from the parent cgroup Signed-off-by: NDaniel P. Berrange <berrange@redhat.com>

Normal practice is for cgroups controllers to be mounted at /sys/fs/cgroup. When setting up a container, /sys is mounted with a new sysfs instance, thus we must re-mount all the cgroups controllers. The complexity is that we must mount them in the same layout as the host OS. ie if 'cpu' and 'cpuacct' were mounted at the same location in the host we must preserve this in the container. Also if any controllers are co-located we must setup symlinks from the individual controller name to the co-located mount-point Signed-off-by: NDaniel P. Berrange <berrange@redhat.com>

As documented in linux.git/Documentation/cgroups/cpuacct.txt, cpuacct.stat returns user and system time in ticks (the same unit used in times(2)). It would be a bit nicer if it were like getrusage(2) and reported timeval contents, or like cpuacct.usage and in nanoseconds, but we can't be picky. * src/util/cgroup.h (virCgroupGetCpuacctStat): New function. * src/util/cgroup.c (virCgroupGetCpuacctStat): Implement it. (virCgroupGetValueStr): Allow for multi-line files. * src/libvirt_private.syms (cgroup.h): Export it.

Adding audit points showed that we were granting too much privilege to qemu; it should not need any mknod rights to recreate any devices. On the other hand, lxc should have all device privileges. The solution is adding a flag parameter. This also lets us restrict write access to read-only disks. * src/util/cgroup.h (virCgroup*Device*): Adjust prototypes. * src/util/cgroup.c (virCgroupAllowDevice) (virCgroupAllowDeviceMajor, virCgroupAllowDevicePath) (virCgroupDenyDevice, virCgroupDenyDeviceMajor) (virCgroupDenyDevicePath): Add parameter. * src/qemu/qemu_driver.c (qemudDomainSaveFlag): Update clients. * src/lxc/lxc_controller.c (lxcSetContainerResources): Likewise. * src/qemu/qemu_cgroup.c: Likewise.
