[Userland] [OpenIndiana Distribution - Bug #4603] ntpd tries to bind to a link-local address

[illumos project]

Issue #4603 has been updated by Gary Mills.


Okay, I see now why I was misled.  The NTP package in oi_151a9 is labelled incorrectly.  It looks like an older version:
@
$ pkg info ntp 
          Name: service/network/ntp
       Summary: Network Time Protocol Daemon v4
   Description: Network Time Protocol v4, NTP Daemon and Utilities (4.2.5)
      Category: System/Services
         State: Installed
     Publisher: openindiana.org
       Version: 4.2.5.200
 Build Release: 5.11
        Branch: 0.151.1.9
Packaging Date: 17 January, 2014 08:32:48 PM 
          Size: 3.91 MB
          FMRI: pkg://openindiana.org/service/network/ntp@4.2.5.200,5.11-0.151.1.9:20140117T203248Z
@
but actually is the newer version:
@
$ /usr/lib/inet/ntpd -? 2>&1 | head
ntpd - NTP daemon program - Ver. 4.2.7p411
Usage:  ntpd [ -<flag> [<val>] | --<name>[{=| }<val>] ]... \
		[ <server1> ... <serverN> ]
...
@
So, the real problem is still that ntpd version 4.2.7p411 tries to bind to a link-local address.  It does this frequently, resulting in many errors like this one:
@Feb 21 15:41:34 ati ntpd[345]: [ID 702911 daemon.error] bind(55) AF_INET6 fe80::ca60:ff:fe12:a83c%26%26#123 flags 0x11 failed: Cannot assign requested address
Feb 21 15:41:34 ati ntpd[345]: [ID 702911 daemon.error] unable to create socket on rge0 (6159) for fe80::ca60:ff:fe12:a83c%26#123

Under oi_151a9, the NTP daemon tries periodically to bind to a link-local IPv6 address, logging these errors:
@
Feb 15 13:53:02 ati ntpd[345]: [ID 702911 daemon.error] bind(55) AF_INET6 fe80::ca60:ff:fe12:a83c%26%26#123 flags 0x11 failed: Cannot assign requested address
Feb 15 13:53:02 ati ntpd[345]: [ID 702911 daemon.error] unable to create socket on rge0 (4395) for fe80::ca60:ff:fe12:a83c%26#123
@
It should ignore that address.  I understand that this bug has been fixed for Linux in the ntpd source, but probably not for Solaris-based systems.
