ifconfig -L shows pltime and vltime as zero. Seems that ifconfig was missed in r253970 which changed usage from time_second to time_uptime. ifconfig -L ... inet6 XXXX:XXXX:XXXX:XXXX:YYYY:YYYY:YYYY:YYYY prefixlen 64 autoconf temporary pltime 0 vltime 0 The prefix is learned via router advertisment. tcpdump shows non zero values in the icmp6 packet. A test program that calls SIOCGIFALIFETIME_IN6 shows the value is < wall clock which is the test done by ifconfig. time = 1397314436 ia6t_preferred = 608907 ia6t_expire = 2596107 Fix: Attached patch to use clock_gettime(CLOCK_MONOTONIC_FAST) in ifconfig per r253970 comment. How-To-Repeat: Run "ifconfig -L" with global or ULA IPv6 addresses learned through router advertisment or define an IPv6 address with pltime and vltime: ifconfig IFNAME inet6 2001:DB8::1 pltime 100 vltime 100 ifconfig -L IFNAME inet6
