From cda6d377ec6b2ee2e58d563d0bd7eb313e0165df Mon Sep 17 00:00:00 2001 From: Stephen Hemminger Date: Wed, 25 Mar 2009 21:01:47 -0700 Subject: bridge: bad error handling when adding invalid ether address This fixes an crash when empty bond device is added to a bridge. If an interface with invalid ethernet address (all zero) is added to a bridge, then bridge code detects it when setting up the forward databas entry. But the error unwind is broken, the bridge port object can get freed twice: once when ref count went to zeo, and once by kfree. Since object is never really accessible, just free it.
