Is there a simple method for determining which interface an skb is
being routed from or routed to?
Assume an ipv4 packet to be forwarded has arrived via the aliased
interface eth0:8.
It is possible to use something along the lines of:
struct in_ifaddr *ifa;
struct in_device *in_dev;
in_dev = __in_dev_get(skb->dev);
if (in_dev)
for (ifa = in_dev->ifa_list; ifa; ifa = ifa->ifa_next)
printk("label=%s\n", ifa->ifa_label);
to obtain a listing of the interfaces associated with the device.
But I haven't been able to find an obvious way to determine which label is
correct for the packet, and would appreciate any clues.
