From 1158f762e57c1cdcda631c1c5f339e4853caa82b Mon Sep 17 00:00:00 2001 From: Pavel Emelyanov Date: Fri, 4 Feb 2011 13:02:36 -0800 Subject: [PATCH] bridge: Don't put partly initialized fdb into hash The fdb_create() puts a new fdb into hash with only addr set. This is not good, since there are callers, that search the hash w/o the lock and access all the other its fields. Applies to current netdev tree.
