Leaf directories that have dependencies impacted
by options need a Makefile.depend.options file
to avoid churn in Makefile.depend
DIRDEPS for cases such as OPENSSL, TCP_WRAPPERS etc
can be set in local.dirdeps-options.mk
which can add to those set in Makefile.depend.options
See share/mk/dirdeps-options.mk

This ensures that the program name is included in the output, which
makes it easy to identify the source of error messages printed

These programs parse ND6 Router Advertisement messages; rtsold(8) has
required an SA, SA-14:20.rtsold, for a bug in this code. Thus, they
are good candidates for sandboxing.
The approach taken is to run the main executable in capability mode
and use Casper services to provide functionality that cannot be
implemented within the sandbox. In particular, several custom services
were required.
- A Casper service is used to send Router Solicitation messages on a
raw ICMP6 socket. Initially I took the approach of creating a
socket for each interface upon startup, and connect(2)ing it to
the all-routers multicast group for the interface. This permits
the use of sendmsg(2) in capability mode, but only works if the
interface's link is up when rtsol(d) starts. So, instead, the
rtsold.sendmsg service is used to transmit RS messages on behalf
of the main process. One could alternately define a service
which simply creates and connects a socket for each destination
address, and returns the socket to the sandboxed process. However,
to implement rtsold's -m option we also need to read the ND6 default
router list, and this cannot be done in capability mode.
- rtsold may execute resolvconf(8) in response to RDNSS and DNSSL
options in received RA messages. A Casper service is used to
fork and exec resolvconf(8), and to reap the child process.
- A service is used to determine whether a given interface's
link-local address is useable (i.e., not duplicated or undergoing
DAD). This information is supplied by getifaddrs(3), which reads
a sysctl not available in capability mode. The SIOCGIFCONF socket
ioctl provides equivalent information and can be used in capability
mode, but I decided against it for now because of some limitations
of that interface.
In addition to these new services, cap_syslog(3) is used to send
messages to syslogd.

We would fail to clear DNS search list configuration if a router
stopped specifying the DNSSL RA option. I suspect that the bug
was mostly harmless, as the RDNSS and DNSSL options are typically used
together and omitting the RDNSS option would have the same effect.

Mainly focus on files that use BSD 3-Clause license.
The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.
Special thanks to Wind River for providing access to "The Duke of
Highlander" tool: an older (2014) run over FreeBSD tree was useful as a
starting point.

Because rtsold listens for RAs on a raw socket, it may receive RAs from
interfaces that it does not manage. Such events can result in excessive
logging.

This is rather pedantic, as for most architectures it holds that

- Remove -a from the usage message example dealing with specific
interfaces. -a only makes sense when not specifying an interface,
such that it's to be run on all interfaces
- Fix the pidfile option (it's -p, not -P)
- Change `interfaces` to `interface` to match the manpage

RFC 4861 6.3.4 clearly defines handling multiple RAs in this way.
- RDNSS/DNSSL options from multiple RAs on a single link will be
gathered and sent to resolvconf(8).
- Call "resolvconf -d" only after at least one RDNSS or DNSSL option is
received and then all of them are expired.
- The rtsold.dump output now supports displaying a list of the RA options.
- Use more human-readable expression for logging values of struct timeval.
