| |
Hi,
When there are 2 interfaces dummy0 and eth0:1 (in this order) with same IP and dummy is DOWN, there is no ARP response from eth0:1
In net/ipv4/arp.c:arp_rcv() the code:
if ((tdev = ip_dev_find(tip)) && (tdev->flags & IFF_NOARP))
must be changed to ignore interfaces which are down, i.e. IFF_UP checking is required but the change is very complex.
ip_dev_find() is used in some other places and may be IFF_UP checking is required.
Or may be the user must assign different IP when iface (dummy0) is down ?
Regards,
Julian Anastasov
