Description IBM Bug Proxy 2007-09-19 16:15:18 UTC
=Comment: #0=================================================
Stephanie A. Glass <sglass&#64;us.ibm.com> - 2007-09-19 12:09 EDT
1. Feature Id 	201138
Feature Name 	Enhancing the active-backup mode of the Bonding driver.
Sponsor 	PPC
Category 	Device Drivers and IO
Request Type 	Kernel - Enhancement from IBM

2. Short Description 	Add an option to the Bonding driver so that it could
optionally failover on MAC addresses, rather than requiring all slaves to be
with the same MAC address.
	
3. Describe the Business Case 	This enhancement is required in order to support
bonding on top of the integrated Ethernet device (HEA) on all i/p6 systems and
blades. Without this change, Bonding won't be working effectively, or won't be
working at all (on Blades) on top of HEA. Any p6 customer who needs to rely on
bonding for networking aggregation/failover will be affected if they intend it
on HEA.
Performance Assistance Required?: 	no
Benefits: 	This enhancement is required in order to support bonding on top of
networking devices which may not be handling multiple ports with the same MAC
addresses as expected for the current bonding polling mechanisms.

4. Sponsor Priority: 	1
IBM Confidential: 	no
Code Contribution ?: 	IBM code
Upstream Acceptance: 	In Progress
Component Release Version Target: 	The patch is going to be submitted to kernel
by 9/18 and is targetted to be included in kernel 2.6.24.

Documentation Work: 	yes

5. Hardware to Red Hat:  already available on site

fail_over_mac option for bonding

This patch adds a fail_over_mac option to bonding, to permit active-backup to
function on devices that are displeased by having the MAC duplicated to all
slaves.  Patch against RHEL 2.6.18-43.el5 kernel.

Bonding 'fail over mac' accepted into mainline.

Comment 4 Andy Gospodarek 2007-10-16 19:19:08 UTC
Thanks, Jay.  I'll try and get this added for the next update (5.2).

Comment 5 RHEL Program Management 2007-11-05 17:55:32 UTC
This request was evaluated by Red Hat Product Management for inclusion in a Red
Hat Enterprise Linux maintenance release.  Product Management has requested
further review of this request by Red Hat Engineering, for potential
inclusion in a Red Hat Enterprise Linux Update release for currently deployed
products.  This request is not yet committed for inclusion in an Update
release.

Comment 6 Jay Turner 2007-12-06 20:01:01 UTC
QE ack for RHEL5.2.

Comment 7 Andy Gospodarek 2007-12-06 20:13:39 UTC
My test kernels have been updated to include a patch for this bugzilla.

http://people.redhat.com/agospoda/#rhel5

Please test them and report back your results.

Andy, Do you want this bz re-assigned to you ?  I've built the attached patches
attached here into my kernels (http://people.redhat.com/smoser/rhel5u2)


Comment 9 Andy Gospodarek 2007-12-06 22:38:04 UTC
Sure thing, Scott.  Sorry to steal your thunder on this one, but I did a big
bonding update to 3.2.0 and this got added into the mix.

I gave the 2.6.18-58.el5.gtest.32 kernel a test drive, and it appears to
function as expected (with regard to the fail_over_mac business).

Comment 11 John Jarvis 2007-12-13 18:55:59 UTC
This enhancement request was evaluated by the full Red Hat Enterprise Linux team
for inclusion in a Red Hat Enterprise Linux minor release.   As a result of this
evaluation, Red Hat has tentatively approved inclusion of this feature in the
next Red Hat Enterprise Linux Update minor release.   While it is a goal to
include this enhancement in the next minor release of Red Hat Enterprise Linux,
the enhancement is not yet committed for inclusion in the next minor release
pending the next phase of actual code integration and successful Red Hat and
partner testing.
