Description of problem: If a new ipv6 address is marked tentative (duplicate address detection not yet complete), ntpd will still attempt to bind to it. This will fail, since a tentative address is not yet available for use, and fills syslog with entries like this every 5 minutes: Jun 29 17:10:05 liffey ntpd[1857]: bind() fd 23, family 10, port 123, scope 7, addr fe80::209:5bff:feea:b06f, in6_is_addr_multicast=0 flags=17 fails: Cannot as sign requested address Jun 29 17:10:05 liffey ntpd[1857]: unable to create socket on wlan1 (275) for fe80::209:5bff:feea:b06f#123 Jun 29 17:10:05 liffey ntpd[1857]: failed to initialize interface for address fe80::209:5bff:feea:b06f Jun 29 17:15:05 liffey ntpd[1857]: bind() fd 23, family 10, port 123, scope 7, addr fe80::209:5bff:feea:b06f, in6_is_addr_multicast=0 flags=17 fails: Cannot as sign requested address Jun 29 17:15:05 liffey ntpd[1857]: unable to create socket on wlan1 (276) for fe80::209:5bff:feea:b06f#123 Jun 29 17:15:05 liffey ntpd[1857]: failed to initialize interface for address fe80::209:5bff:feea:b06f ntpd should probably be ignoring ipv6 addresses marked tentative. Version-Release number of selected component (if applicable): ntp-4.2.4p0-2.fc7 How reproducible: always Steps to Reproduce: 1. add a duplicate ipv6 address, so the address is marked tentative $ /sbin/ip -6 addr show wlan1 7: wlan1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qlen 1000 inet6 fe80::209:5bff:feea:b06f/64 scope link tentative valid_lft forever preferred_lft forever Actual results: messages in syslog about ntpd failing to bind to the tentative address Expected results: no messages in syslog, ntpd ignores the address until it is no longer tentative Additional info:
