1d712c0537 traceroute6: Properly calculate UDP checksum
The revision D25604 capsicumize traceroute6. For UDP the send socket was
changed from SOCK_DGRAM to SOCK_RAW and thus the UDP checksum need be
calculated by application itself other than the kernel.

outpacket is filled with zeros by line 707, thus the first round the UDP
checksum is correct. But subsequent rounds outudp->uh_sum will be left
with garbage.

b8ae450f05 traceroute6: Fix Capsicum rights for rcvsock
- Always use distinct sockets for send and recv
- Limit rights on the recv socket

For ICMP6 we were using the same socket for both send and receive, and
we limited rights on the socket such that it's impossible to receive
anything.

5c3bf25fee [traceroute6] Don't do the casper bits when we're not doing casper
This with the previous patch I committed makes traceroute6/traceroute
compile fine when libcasper isn't enabled.

This complains strongly with unused variables and such when compiled
with gcc-6 on mips32.

Tested:

* compiled/run on mips32 hardware (AR9344)

3303e9bc22 Fix the length of probe packets when using UDP.
Since https://svnweb.freebsd.org/changeset/base/365378 a raw socket is
used for sending UDP probe packets instead of a UDP socket. So don't
compensate for the UDP header anymore.

2d0fb1b3c1 Simplify code, no functional change.
Since https://svnweb.freebsd.org/base?view=revision&revision=365378
UDP is handled the same way as SCTP and TCP (using a raw socket).
Therefore use the same code path.

sufficient alignment in practice.

51eff8efd9 When using SCTP for sending probe packets, use INIT chunks for payloads
larger than or equal to 32 bytes. For smaller probe packets, keep using
SHUTDOWN-ACK chunks, possibly bundled with a PAD chunk.
Packets with INIT chunks more likely pass through firewalls. Therefore,
use them when possible.

8a16b7a18f General further adoption of SPDX licensing ID tags.
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.

aa96470cc9 * Update function definitions.
* Ensure that the datalen always describes the length after the IPv6
  header consistently, not matter which protocol us used for probes..
* Document that the default length is 20, not 12.
* Don't send inormation in probe packets which is not needed or
  even checked when the responses are processed.
* Address CID 978587.

This is mainly a cleanup preparing the addition of SCTP and TCP
as possible probe packet protocols.

59876f938e When processing multi-path ip6 routers, place each router entry on its
own line.  We made this change in traceroute(8) some time ago.  This
is particularly useful when you are not resolving hostnames since ip6
addresses can be quite long, and lines wrap fairly easily in the
multi-path router case.
