* libcgroup: New API interfaces for task placementDhaval Giani2008-08-131-0/+4
| | | | | | | | | | | | | | | | | | | | | | | 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
* libcgroup: Configuration and parsing updates (v2)Dhaval Giani2008-08-131-1/+1
| | | | | | | | | | | | | | | | | | | | | Dhaval, wanted a patch with -p1 generated so that he can apply it and use it with quilt. Here goes Testing Tested with samples/cgconfig.conf (NOTE: expects user balbir to be present on the system, feel free to change and test). TODO 1. Add hooks for other controllers, namely memory, cpuacct and cpuset Signed-off-by: Balbir Singh <balbir@linux.vnet.ibm.com> Signed-off-by: Dhaval Giani <dhaval@linux.vnet.ibm.com> git-svn-id: https://libcg.svn.sourceforge.net/svnroot/libcg/trunk@134 4f4bb910-9a46-0410-90c8-c897d4f1cd53
* libcgroup: Add cgroup_?et_value_* APIsDhaval Giani2008-08-121-0/+16
| | | | | | | | | | | | Adding in APIs which allow you to set and get values from a cgroup controller. Use cgroup_get_controller to get a controller, and then use cgroup_?et_value_* API for your requirement.

* libcgroup: Add API to get the cgroup from name (Breaks existing API)Dhaval Giani2008-08-121-2/+5
| | | | | | | | | | | | | | | This patch breaks API. There are no known users at the moment so it is fine. cgroup_new_cgroup now takes in only a name argument. The uids and gids are set by a new API, cgroup_?et_uid_gid() Signed-off-by: Dhaval Giani <dhaval@linux.vnet.ibm.com> Acked-by: Vivek Goyal <vgoyal@redhat.com> git-svn-id: https://libcg.svn.sourceforge.net/svnroot/libcg/trunk@125 4f4bb910-9a46-0410-90c8-c897d4f1cd53
* libcgroup: Add an API to allow comparision of cgroupsDhaval Giani2008-08-121-0/+5
| | | | | | | | | | | Allows you to compare two cgroups. Their values need to be equal. NULL cgroups are invalid. Signed-off-by: Dhaval Giani <dhaval@linux.vnet.ibm.com> git-svn-id: https://libcg.svn.sourceforge.net/svnroot/libcg/trunk@124 4f4bb910-9a46-0410-90c8-c897d4f1cd53
* libcgroup: Add new API to get cgroup data structure from filesystemDhaval Giani2008-08-061-0/+1
| | | | | | | | | | | | | | | | | New API to get the cgroup datastructure from the mounted filesystem. It accepts the cgroup datastructure with the name of the cgroup which has to populated across various mountpoints. TODO: More testing.
