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.

Description IBM Bug Proxy 2010-09-10 21:01:29 UTC 
1. Feature Overview:
Feature Id: [67161]
a. Name of Feature: [6.1 FEAT] libvirt support for 802.1Qbg pre-associate request
b. Feature Description
The VSI protocol specification for 802.1Qbg defines a PRE-ASSOCIATE request tonotify a bridge to
prepare for association (via lldpad in the case of RHEL 6).  libvirt does currently not support this.


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

Arch Specificity: ---
Affects Kernel Modules: Field does not exist
Delivery Mechanism: Backport
Category: other
Request Type: Package - Version Update
d. Upstream Acceptance: Field does not exist
Sponsor Priority P3
f. Severity: high
IBM Confidential: No
Code Contribution: IBM code
g. Component Version Target:
---

3. Business Case
Without support for the PRE-ASSOCIATE request the 802.1Qbg implementation will not be standard
conform and therefore not be able to work with standard conforming  switches.

Code Upstream Status: Not Started
Comment 3 Daniel Veillard 2010-10-20 15:55:59 UTC 
Patches sent and applied upstream before the end of the year should be able to make it to 6.1,

I don't think that's correct.  PRE-ASSOCIATE is optional AFAIK.  The current implementation will send only an ASSOCIATE request, so adding PRE-ASSOCIATE is more like a useful optimization than being standards compliant.

Patch has been submitted to libvir mailing list:
https://www.redhat.com/archives/libvir-list/2010-November/msg00857.html
Comment 6 Dave Allan 2010-11-23 03:59:36 UTC 
I'm setting cond nak patch simply to reflect that the patch has not yet been accepted upstream.
Comment 7 Stefan Berger 2010-11-30 20:54:32 UTC 
The patch has been pushed into the libvirt repository today:

http://libvirt.org/git/?p=libvirt.git;a=commitdiff;h=c2b38277b3a362ee0d75e0946478ebce801496f4

Comment 8 Dave Allan 2010-11-30 22:55:10 UTC 
Thanks Stefan; cond nak removed.
Comment 9 John Jarvis 2010-12-01 03:12:50 UTC 
IBM is signed up to test and provide feedback, setting OtherQA.
Comment 11 John Jarvis 2011-01-14 02:58:44 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.

Hi John Jarvis,

Would you please check if feedback is supplied according to comment 9?


Thanks,
Chun Cui
Comment 14 John Jarvis 2011-02-22 02:43:30 UTC 
No, 6.1 Alpha hasn't even gone out to partners yet.
Comment 15 Cui Chun 2011-02-22 03:20:08 UTC 
Thank John for your feedback.

Please let me know or update in this bug after partners check.
Comment 16 Stefan Berger 2011-02-22 03:43:44 UTC 
We likely have a dependency on a recently found libnl bug that needs fixing for
802.1Qb{g|h} to properly work.
