* libcgroup: Better error reporting for libcgroupDhaval Giani2008-12-091-0/+7
| | | | | | | | | | | | | | | | From: Ankita Garg <ankita@in.ibm.com> This patch adds human readable error messages to the configuration parser. The error lookup is implemented as a simple table, indexed by the error. TODO: Save errno at ECGOTHER and pass it down as cgroup_lasterror.

* libcgroup: Change how cgroup_get_cgroup worksDhaval Giani2008-09-291-1/+1
| | | | | | | | | | | | | | Since we will not deprecate API now, and will do so with the next release, let's include this one in and get the API right. With this pathc, we now return int type, and the pointer passed as the argument redirects to the cgroup we are reading.

* The automatic classification engine (cgexec, cgclassify, pam_cgroup)Balbir Singh2008-09-291-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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).

* This patch adds cgroup_create_cgroup_from_parent() API. I've tested itBalbir Singh2008-08-221-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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

| | | | | | | | | | | | | | | | | | | | | | | 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
