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.

The broadcast addresses might be hard/not needed except for 255.255.255.255 which is already handled, but I have a patch for the multicast part.

The upstream ticket was proposed for 1.10 so I moved the RHEL bug to RHEL7.

Fixed upstream.

--- Additional comment from Michael Hampton on 2013-07-30 02:51:57 EDT ---

Any chance of getting this bugfix in EL6? This is causing dynamic DNS address updates for RFC1918 A records to randomly fail.

--- Additional comment from Alexander Bokovoy on 2013-07-30 02:58:24 EDT ---

We really need this in RHEL 6. IN_MULTICAST(addr) is not the same as IN_MULTICAST(ntohl(addr)) on Intel architecture.As result of wrong byte order many innocent addresses are filtered out.

--- Additional comment from Petr Spacek on 2013-07-30 07:52:37 EDT ---

AFAIK it doesn't make much sense to filter IPv4 multicast addresses, because they are not considered valid *source* addresses. Multicast address is valid only as *destination* address, so no multicast address should ever appear on the IPv4 interface.

Comment 2 Jakub Hrozek 2013-09-25 23:28:47 UTC
Steps to Reproduce:
1. In LDAP, fill a user entry with a "sudoHost" attribute with a subnet: "192.168.101.0/24"
2. On a fresh Fedora 19 machine which is in the subnet "192.168.101.0/24", and which has NetworkManager service installed, the user tries to execute the command "sudo -l"

Actual results:
"User xxxx is not allowed to run sudo on machine"

Expected results:
The user is allowed to run sudo on the machine
