ixgbe: check for vfs outside of sriov_num_vfs before dereference The check for vfinfo is not sufficient because it does not protect against specifying vf that is outside of sriov_num_vfs range. All of the ndo functions have a check for it except for ixgbevf_ndo_set_spoofcheck(). The following patch is all we need to protect against this panic: ip link set p96p1 vf 0 spoofchk off BUG: unable to handle kernel NULL pointer dereference at 0000000000000052 IP: [<ffffffffa044a1c1>] ixgbe_ndo_set_vf_spoofchk+0x51/0x150 [ixgbe] Reported-by: Thierry Herbelot <thierry.herbelot@6wind.com> Signed-off-by: Emil Tantilov <emil.s.tantilov@intel.com> Acked-by: Thierry Herbelot <thierry.herbelot@6wind.com> Signed-off-by: Jeff Kirsher <jeffrey.t.kirsher@intel.com>
