| Subject: ipv4: return valid RTA_IIF on ip route get |
| |
| From: Julian Anastasov <ja@ssi.bg> |
| |
| [ Upstream commit 91146153da2feab18efab2e13b0945b6bb704ded ] |
| |
| Extend commit 13378cad02afc2adc6c0e07fca03903c7ada0b37 |
| ("ipv4: Change rt->rt_iif encoding.") from 3.6 to return valid |
| RTA_IIF on 'ip route get ... iif DEVICE' instead of rt_iif 0 |
| which is displayed as 'iif *'. |
| |
| inet_iif is not appropriate to use because skb_iif is not set. |
| Use the skb->dev->ifindex instead. |
