 1.20  23-Mar-2021  christos print function names as %s: not <%s> everywhere for consistency.
 1.19  03-Dec-2019  msaitoh s/upate/update/ in comment.
 1.18  20-Apr-2018  roy branches: 1.18.2;
Lack of timeout is a programming error, so use an assert in it's place.
While here, improve the error reported if malloc fails.
 1.17  20-Apr-2018  roy Use EXIT_FAILURE instead of an arbtitary number.
 1.16  20-Apr-2018  roy Allow timers to exist but be inactive.
This will be used in a future commit.
 1.15  20-Apr-2018  roy White space police.
 1.14  06-Nov-2017  christos branches: 1.14.2;
Change the meaning of the 'D' flag to print errors to stderr instead of
syslog(3) and exit if poll(2) fails (intended to be used with unit-tests).
 1.13  11-Nov-2015  ozaki-r branches: 1.13.8;
Introduce rump.rtadvd

It is used to write ATF tests for RA.

From s-yamaguchi@IIJ.
 1.12  05-Jun-2015  roy Use clock_gettime(2) instead of gettimeofday(2) so we can use a monotonic
clock rather than the wall clock.
Use timespec rather than timeval structs to make this transition easier.
Kill custom timeval comparison functions in favor of timespeccmp(3).
 1.11  13-Dec-2012  roy Remove the iflist array and store ifflags in rainfo.

Add support for SIGHUP to re-read the configuration for each interface.
If an invalid configuration is found, we continue to use the old one;
otherwise we expire the current one and then start advertising the new one.

Specififed interfaces don't have to exist at startup.
If specified interfaces arrive, load their config and start advertising.
If they depart, remove their rainfo structure and continue.

Fixes PR/43881 and PR/47311
 1.10  10-Dec-2011  roy branches: 1.10.6;
Add RDNSS and DNSSL support, RFC6106.
Replace custom lists with TAILQ lists.
Clean up plently of signed vs unsigned warnings and set WARNS=4.

Adapted from FreeBSD.
 1.9  05-Mar-2006  rpaulo branches: 1.9.42;
NDP-related improvements:
RFC4191
- supports host-side router-preference

RFC3542
- if DAD fails on a interface, disables IPv6 operation on the
interface
- don't advertise MLD report before DAD finishes

Others
- fixes integer overflow for valid and preferred lifetimes
- improves timer granularity for MLD, using callout-timer.
- reflects rtadvd's IPv6 host variable information into kernel
(router only)
- adds a sysctl option to enable/disable pMTUd for multicast
packets
- performs NUD on PPP/GRE interface by default
- Redirect works regardless of ip6_accept_rtadv
- removes RFC1885-related code

KNF, fix time printing formats.

Don't start another copy of rtadvd if one is running.

PR/52618: Shinichi Doyashiki: Don't exit if adding interface to multicast
group fails. This happens with empty vlan interfaces
- make syscalls checks against -1
- fix errors to print %s: instead of <%s>
XXX: if_vlan is the only pseudo interface in net/ that returns such an
error..

Kill rtadvd surely even if the tests fail in the middle
It may help PR bin/52701.

Change the meaning of the D flag to print errors to stderr instead of
syslog(3) and exit if poll(2) fails (intended to be used with unit-tests).

Mark expandm as preserving format strings.

Let rtadvd not use syslog for logging
Thanks to christos@ now rtadvd can log via stderr instead of syslog
by -D option.
