Bug Fix(es):
Previously, guest virtual machines (VMs) on a Hyper-V server cluster got in some cases rebooted during the graceful node failover test, because the host kept sending heartbeat packets independently of guests responding to them. This update fixes the bug by properly responding to all the heartbeat messages in the queue, even if they are pending. As a result, guest VMs no longer get rebooted under the described circumstances. (BZ#1397737)
From Red Hat Enterprise Linux 6.6 to 6.8, the IPv6 routing cache occasionally showed incorrect values. This update fixes the DST_NOCOUNT mechanism, and the IPv6 routing cache now shows correct values. (BZ#1391973)
Previously, memory corruption by copying data into the wrong memory locations sometimes occurred, because the __copy_tofrom_user() function was returning incorrect values. This update fixes the __copy_tofrom_user() function so that it no longer returns larger values than the number of bytes it was asked to copy. As a result, memory corruption no longer occurs in he described scenario. (BZ#1398182)
