-From b7841cf7b919b16d1bd4619154bf7cb4c22b4ccd Mon Sep 17 00:00:00 2001
-From: Paul Marks <paul@pmarks.net>
-Date: Mon, 14 Jan 2013 01:39:10 +0000
-Subject: ntpd: fix incorrect m_status field in outgoing packets. Closes 5120
-
-When using busybox ntpd with an NTPv3 client and NTPv4 server (or vice
-versa), the version numbers can be incorrectly ORed together, yielding
-the bogus value of "NTPv7".  This makes ntpd unusable with clients
-such as Chrony and Windows "Internet Time".
-
-This patch avoids the version mangling, by copying only the Leap
-Indicator bits from the server's status field.
