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.

Red Hat Product Errata RHBA-2013:0518 0 normal SHIPPED_LIVE initscripts bug fix and enhancement update 2013-02-20 21:29:01 UTC

Description james.greene 2011-06-17 16:27:27 UTC 
Description of problem:

/etc/sysconfig/network-scripts/ifdown-eth needs the same type of patch as ifup received as per bugs 462095/676708:

143c143
<     if echo ${DEVICE} | LANG=C egrep -v '(:)' | LANG=C egrep -q '(eth|bond)[0-9]*\.[0-9][0-9]?[0-9]?[0-9]?' \
---
>     if echo ${DEVICE} | LANG=C egrep -v '(:)' | LANG=C egrep -q '.+\.[0-9][0-9]?[0-9]?[0-9]?' \

The new initscripts rpm only patches ifup.

This supports functional/descriptive naming of interfaces (including biosdevname-style) where VLANs are used.

Without this patch, the vconfig rem is never called to remove the VLAN tag, leaving orphan VLAN config entries.


Version-Release number of selected component (if applicable):

All Redhat 5 and 6 with VLAN config support in ifup/ifdown-eth


How reproducible:

Every time.


Steps to Reproduce:
1. Confirm no VLAN tag set by cat /proc/net/vlan/config
2. Configure a VLAN interface on a descriptively named device, eg, "data.555" in ifcfg-data.555 and run "ifup data.555". (Requires current initscripts or manual edit to ifup.)
3. "ifdown data.555"   (no errors reported)
4. See that VLAN 555 still present in /proc/net/vlan/config
  
Actual results:

VLAN 555 tag still in /proc/net/vlan/config, data.555@data device still exists.


Expected results:

VLAN 555 tag should be removed from /proc/net/vlan/config, and data.555@data devices does not exist.


Additional info:

Minor but easily fixed.

test patch

Just from reading the code, this seems far simpler than worrying about the device name.

Will require some testing on all the earlier releases. Does this work for you?
Comment 3 Suzanne Logcher 2011-10-06 18:50:25 UTC 
Since RHEL 6.2 External Beta has begun, and this bug remains
unresolved, it has been rejected as it is not proposed as
exception or blocker.
               
Red Hat invites you to ask your support representative to
propose this request, if appropriate and relevant, in the
next release of Red Hat Enterprise Linux.
Comment 4 Lukáš Nykrýn 2012-06-08 08:56:31 UTC 
Bill's patch looks correct to me, but can you please also try it?
Comment 5 Meni Yakove 2012-09-03 07:28:35 UTC 
Test Bill patch on RHEL 6.3 and VLAN was deleted (em1.200).
