463185 – [LTC 6.0 FEAT] 201699:libcgroup (User space library for resource management)

RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

1. Feature Overview:
Feature Id:	[201699]
a. Name of Feature:	libcgroup (User space library for resource management)
b. Feature Description
The current mainline Linux Kernel has resource management features integrated into it. This includes
the CPU controller, memory controller, CPU accounting, task grouping framework and statistics
framework. More work is being aggressively carried out and more controllers are being proposed. The
package (libcgroup) provides user space ABI to allow applications to deal with the internals of the
control group filesystem.

Additional Comments:	We maintain the library at libcg.sf.net and we've got good community traction.
We already have the package in F9 and F10. We'll continue to develop/enhance the package to
iteratively add features.

2. Feature Details:
Sponsor:	LTC
Architectures:
x86
x86_64
ppc64

Arch Specificity: Purely Common Code
Delivery Mechanism: Direct from community
Category:	Kernel
Request Type:	Package - Feature from IBM
d. Upstream Acceptance:	Accepted
Sponsor Priority	1
f. Severity: High
IBM Confidential:	no
Code Contribution:	IBM code
g. Component Version Target:	libcgroup 0.1c

3. Business Case
Resource management is one of the most important outstanding features which Linux lacks relative to
other enterprise operating systems. Enabling this feature provides a user space API and management
to a number of IBM management products (eg: DB2, LoadLeveler).

Comment 1 IBM Bug Proxy 2009-03-03 04:40:32 UTC

The version of libcgroup to be picked up is 0.33 which is already available in rawhide.

Comment 3 John Jarvis 2009-12-17 20:24:29 UTC

This enhancement request was evaluated by the full Red Hat Enterprise Linux 
team for inclusion in a Red Hat Enterprise Linux major release.   As a 
result of this evaluation, Red Hat has tentatively approved inclusion of 
this feature in the next Red Hat Enterprise Linux major release.   
While it is a goal to include this enhancement in the next major release 
of Red Hat Enterprise Linux, the enhancement is not yet committed for 
inclusion in the next major release pending the next phase of actual 
code integration and successful Red Hat and partner testing.
