Description Paolo Bonzini 2010-08-09 15:17:11 EDT

+++ This bug was initially created as a clone of Bug #622574 +++

The following patches upstream implement gratuitous ARP notification.  They would be useful in RHEL5 and RHEL6 as well.

eefef1cf (net: add ARP notify option for devices, 2009-02-01)
a21090cf (ipv4: arp_notify address list bug, 2009-10-07)
http://kerneltrap.org/mailarchive/linux-netdev/2010/5/26/6278032
http://kerneltrap.org/mailarchive/linux-netdev/2010/5/26/6278033
http://kerneltrap.org/mailarchive/linux-netdev/2010/5/26/6278031

The last three are scheduled for merge in 2.6.36 (http://www.spinics.net/lists/netdev/msg137066.html).

See http://lists.xensource.com/archives/html/xen-devel/2009-06/msg00185.html for a report of this happening.

Comment 1 Paolo Bonzini 2010-08-12 00:15:02 EDT

The patches are scheduled for 2.6.32.y, so we'll probably get them from there.
