From c01003c20563d1e75ec9828d21743919d2b43977 Mon Sep 17 00:00:00 2001 From: Patrick McHardy Date: Thu, 29 Mar 2007 11:46:52 -0700 Subject: [IFB]: Fix crash on input device removal The input_device pointer is not refcounted, which means the device may disappear while packets are queued, causing a crash when ifb passes packets with a stale skb->dev pointer to netif_rx(). Fix by storing the interface index instead and do a lookup where neccessary. Signed-off-by: Patrick McHardy Acked-by: Jamal Hadi Salim Signed-off-by: David S.
