- Implement RDNSS and DNSSL options (RFC 6106, IPv6 Router Advertisement
Options for DNS Configuration) into rtadvd(8) and rtsold(8). DNS
information received by rtsold(8) will go to resolv.conf(5) by
resolvconf(8) script. This is based on work by J.R. Oldroyd (kern/156259)
but revised extensively[1].
- rtadvd(8) now supports "noifprefix" to disable gathering on-link prefixes
from interfaces when no "addr" is specified[2]. An entry in rtadvd.conf
with "noifprefix" + no "addr" generates an RA message with no prefix
information option.
- rtadvd(8) now supports RTM_IFANNOUNCE message to fix crashes when an
interface is added or removed.
- Correct bogus ND_OPT_ROUTE_INFO value to one in RFC 4191.
