Note: This bug is displayed in read-only format because the product is no longer active in Red Hat Bugzilla.
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 Hayato Kakuta 2011-08-01 06:44:25 UTC 
Description of problem:

IGMP snooping: bridge is unable to limit sending of IGMP/IGMPv2
membership report.

When a bridge receives an IGMP membership report,
it is forwarded to all ports regardless of
presence of multicast routers.  Such an unsolicited
report will cause its recipient Host and VMs to cease
responding, and the bridge will stop forwarding
multicast packets to them as a result.

an upstream commit already has a fix:

  commit 62b2bcb49cca72f6d3f39f831127a6ab315a475d

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

  kernel-2.6.32-131.6.1.el6
Comment 2 Neil Horman 2011-09-21 12:56:14 UTC 
This commit has already been pulled in by 716263.  Kernel 2.6.32-168 or later will have the required fix.
