From ef47c6a7b8e36e3b160433673b1b68db799aabcd Mon Sep 17 00:00:00 2001 From: Patrick McHardy Date: Tue, 27 Jun 2006 03:01:48 -0700 Subject: [NETFILTER]: ip_queue/nfnetlink_queue: drop bridge port references when dev disappears When a device that is acting as a bridge port is unregistered, the ip_queue/nfnetlink_queue notifier doesn't check if its one of physindev/physoutdev and doesn't release the references if it is.
