Is there any way to figure out whether the access is indeed in NetworkManager or a bug in a library that NM links to?

Comment 2 Jirka Klimes 2011-06-15 07:43:26 UTC

I've tested that on a ia64 machine.
The problem is in libnl source code present in RHEL's NM.

The libnl upstream fixed that. So, we should take the patch:

Comment 3 RHEL Program Management 2011-06-21 05:33:27 UTC

This request was evaluated by Red Hat Product Management for inclusion in Red Hat Enterprise Linux 5.7 and Red Hat does not plan to fix this issue the currently developed update.

Contact your manager or support representative in case you need to escalate this bug.

Comment 5 RHEL Program Management 2011-09-23 00:48:19 UTC

This request was evaluated by Red Hat Product Management for
inclusion in the current release of Red Hat Enterprise Linux.
Because the affected component is not scheduled to be updated in the
current release, Red Hat is unfortunately unable to address this
request at this time. 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 7 Dan Williams 2013-02-19 05:19:54 UTC

Not going to happen for RHEL5 but shouldn't be an issue with RHEL6.
