* This patch adds cgroup_create_cgroup_from_parent() API. I've tested itBalbir Singh2008-08-224-22/+196
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | with a modified version of libcg_ba (basic acceptance tests), that I'll send out later. 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. I've also updated the basic acceptance test (libcg_ba.cpp) Signed-off-by: Balbir Singh <balbir@linux.vnet.ibm.com> git-svn-id: https://libcg.svn.sourceforge.net/svnroot/libcg/trunk@165 4f4bb910-9a46-0410-90c8-c897d4f1cd53

| | | | | | | | | | | | | | | | | | | | | | | cgroup From: Vivek Goyal <vgoyal@redhat.com> o A simple pam module pam_cgroup for placement of tasks in right cgroup.

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.

* libcgroup: Fix test cases to use CPU controller if availableDhaval Giani2008-07-021-2/+10
| | | | | | | | | | | | | The test cases used the memory controller. This is not a good idea since most distro kernels don't enable it by default. For the moment I'm setting it to use CPU if memory is not found, but in the longer term I am planning to set it to use CPU first and then memory.

| | | | | | | | | | | | | | libcgroup: adds sanity check in libcgroup testcases binary This patch adds a sanity check on cgroup file system info in testcases. If cgroup filesystem is not mounted and script sends the info as mounted, then the binar would have failed. This patch handles that.
