2013-12-07ntpd: do not invalidate datapoints after stepDenys Vlasenko
Used to set p->filter_datapoint[i].d_dispersion = MAXDISP and clear reachable bits, but this proved to be too agressive: after step (tested with suspinding laptop for ~30 secs), this caused all previous data to be considered invalid, making us needing to collect full ~8 datapoins per peer after step in order to start trusting them. In turn, this was making poll interval decrease even after step was done. (Poll interval decreases already before step in this scenario, because we see large offsets and end up with no good peer to select). function old new delta reset_peer_stats 157 139 -18 Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

2013-01-14ntpd: fix incorrect m_status field in outgoing packets. Closes 5120Paul Marks
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.

2012-12-19CONFIG_PID_FILE_PATH: new configuration option for pidfile pathsAnthony G. Basile
We set a default path for the directory where pidfiles are create when FEATURE_PIDFILE is selected. The default has no effect on applets which must specify a pidfile path on the command line to run, and it can be overridden by applets which optionally allow the user to specify the pidfile path. We also add pidfile write/remove support for klogd, ntpd and watchdog. For syslogd, we add a missing remove_pidfile() for better cleanup on daemon exit. Signed-off-by: Anthony G.
