Bug Fixes

BZ#773544

Previously, the cgrulesengd daemon ignored the "--sticky" option of the cgexec command and, as a consequence, moved a process to another cgroup when the process called the setuid() or setgid() functions even if the process had to be stuck to the current cgroup. This bug is now fixed and the cgrulesengd daemon now checks whether the process is "sticky" or not when the process calls setuid or setgid.

BZ#819137

Previously, the lscgroup command dropped the first character of a path unless prefixed with a slash, which led to lscgroup generating invalid paths. This bug is now fixed and the generated paths are now correct.

BZ#849757

Previously, adding a cgroup after the cgrulesengd daemon had started did not work. As a consequence, if a directory was created after cgrulesengd was already started, any /etc/cgrules.conf configuration for that directory would not be processed. With this update, a routine has been added to scan the cgrules.conf file and move matching running tasks in the /proc/pid/ directory into configured cgroups. This new routine is called at init time and also after inotify events on cgroups. With this update, a routine has been added to scan the cgrules.conf file and move matching running tasks into configured cgroups.

BZ#869990

Previously, the cgconfig service was not working properly with read-only file systems. As a consequence, cgconfig was not able to start with the default configuration on a Red Hat Enterprise Virtualization Hypervisor system. This update adds a check for the read-only file systems to the cgconfig service and it now works as expected with the default configuration on Red Hat Enterprise Virtualization Hypervisor systems.
