Date: Thu, 6 Mar 2014 13:03:50 -0500 From: Sasha Levin <sasha.levin@...cle.com> To: fubar@...ibm.com, vfalico@...hat.com, andy@...yhouse.net Cc: davem@...emloft.net, netdev@...r.kernel.org, linux-kernel@...r.kernel.org, nikolay@...hat.com, Sasha Levin <sasha.levin@...cle.com> Subject: [PATCH] bonding: correctly handle out of range parameters for lp_interval We didn't correctly check cases where the value for lp_interval is not within the legal range due to a missing table terminator. This would let userspace trigger a kernel panic by specifying a value out of range: echo -1 > /sys/devices/virtual/net/bond0/bonding/lp_interval Introduced by commit "bonding: add infrastructure for an option API".
