* The automatic classification engine (cgexec, cgclassify, pam_cgroup)Balbir Singh2008-09-295-1/+149
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | classify tasks. It is useful for an application to know where it has been classified. I propose to add a new API cgroup_get_current_controller_path() that returns the current classification directory for the specified controller. One can easily add on and build new API that will return paths of all mounted controllers, but I want to start with something simple and useful. I've also added a bunch of test cases for the same purpose. Test output # ./pathtest.sh Test FAIL, get path failed for controller cpuset Test PASS, controller cpu path /default Test PASS, controller cpuacct path /default Test PASS, controller memory path /default Test FAIL, get path failed for controller memrlimit I mounted just cpu, cpuacct and memory, thus the path for cpuset and memrlimit could not be found (as expected).

I've also fixed a couple of bugs, I'll list them in order and if desired, I'll split out the patches so that the enhancements can be separate from the bug fixes 1. Fix cg_create_control_group() to succeed if the directory already exists 2. We can't always append a control_file, we need to open it "r+" 3. It's OK for writing values to a control_file to fail, since some of them are read-only and some may not exist in hierarchies below the root 4. Skip over directories while trying to read control file's name value pairs 5. In cg_rd_ctlr_file we don't allocate any memory to value, directly fscanf into it, that's been fixed 6. There might be more fixes that might already be present in trunk, since I hope I've not redone a lot of the fixes, I had branched of trunk very recently Changelog v2 ------------ 1. Refactor cgroup_free_controllers() and use it in cgroup_create_cgroup_from_parent() 2. Check for strdup failure 3. Check if dst == src TODO: 1. Use cg_add_controller() API 2. Use cg_add_value_string() API I'll send out patches for the TODOs later.

* cgclassify: A command line tool to classify/re-classify already running taskDhaval Giani2008-08-132-3/+156
| | | | | | | | | | | | | | | | | | | | | | | From: Vivek Goyal <vgoyal@redhat.com> o cgclassify, a command line tool to put a list of pids to the right cgroup based on rules in /etc/cgrules.conf. It can be mainly used for reclassification of tasks which are already running. Can think of two use cases. - During initial bootup, after cgroups are mounted, one needs to move tasks (started beofore cgroups were mounted) into right cgroup. - Once can choose to reclassify the tasks if admin has changed the rules and thinks a group of tasks should reclassified based on new rules.

| | | | | | | | | | | | | | | | | | | | | | | From: Vivek Goyal <vgoyal@redhat.com> Enhancement to libcg to do following. - Parse the /etc/cgrules.conf file and place the task in the right cgroup. - Exported two APIs which can place the task based on /etc/cgrules.conf or based on cgroup explicitly specified by the caller. - There can be multiple users. - PAM module (pam_cgroup) - cgexec tool - cgclassify tool - APIs can be directly used by other cgroup aware user progarams. - Classification daemon Signed-off-by: Vivek Goyal <vgoyal@redhat.com> Signed-off-by: Dhaval Giani <dhaval@linux.vnet.ibm.com> git-svn-id: https://libcg.svn.sourceforge.net/svnroot/libcg/trunk@136 4f4bb910-9a46-0410-90c8-c897d4f1cd53
