Hi,
 As part of getting ready for the end of the world as we know it I just upgraded  a BBB to 4.2.8p3 and discovered that the leap_armed system status is not updated if a leapsecond file is loaded dynamically. 

Here’s the trace:

I restarted ntpd after a build and installing a leap second file. The log showed that the leapsecond file was not picked up.

Jun  6 22:10:10 bb2 ntpd[1469]: Listen normally on 5 eth0 [fe80::7aa5:4ff:fecc:d05d%2]:123
Jun  6 22:10:10 bb2 ntpd[1469]: Listening on routing socket on fd #22 for interface updates
Jun  6 22:10:10 bb2 ntpd[1469]: leapsecond file ('/etc/ntp/leapdir/leapsecs'): stat failed: No such file or directory
Jun  6 22:10:13 bb2 ntpd[1469]: Soliciting pool server 85.21.78.91

I then corrected the error, which was due to a finger check on the directory name and waited for ntpd to pick up the now available file, which it did an hour later. 

Jun  6 23:10:10 bb2 ntpd[1469]: leapsecond file ('/etc/ntp/leapdir/leapsecs'): loaded, expire=2015-12-01T00:00Z last=2015-07-01T00:00Z ofs=36

I thought that would be the end of the story, but a routine check this morning showed that the leap_armed status was not set.

mike at bb2:~$ ntpq -c rv
associd=0 status=0615 leap_none, sync_ntp, 1 event, clock_sync,
version="ntpd 4.2.8p3-RC1 at 1.3265-o Sat Jun  6 14:56:55 UTC 2015 (1)",
processor="armv7l", system="Linux/3.8.13-bone47", leap=00, stratum=2,

I then restarted ntpd to check if that helped.

So, it’s fixed by a reboot. Anyone seen this?
