09139a4537 Implement support for RFC 3514 (The Security Flag in the IPv4 Header).
(See: ftp://ftp.rfc-editor.org/in-notes/rfc3514.txt)

This fulfills the host requirements for userland support by
way of the setsockopt() IP_EVIL_INTENT message.

There are three sysctl tunables provided to govern system behavior.

	net.inet.ip.rfc3514:

		Enables support for rfc3514.  As this is an
		Informational RFC and support is not yet widespread
		this option is disabled by default.

	net.inet.ip.hear_no_evil

		 If set the host will discard all received evil packets.

	net.inet.ip.speak_no_evil

		If set the host will discard all transmitted evil packets.

The IP statistics counter 'ips_evil' (available via 'netstat') provides
information on the number of 'evil' packets recieved.

For reference, the '-E' option to 'ping' has been provided to demonstrate
and test the implementation.

2510719736 The -A option (beep when packets are dropped) didn't work quite
right; after a single packet was dropped it beeped after every
transmission.

Change its implementation to only output a bell when there is an
increase in the maximum value of the number of packets that were
sent but not yet received. This has the benefit that even for very
long round-trip times, ping -A will do roughly the right thing
after a few inital false-positives.

c4d9468ea0 mdoc(7) police:
Avoid using parenthesis enclosure macros (.Pq and .Po/.Pc) with plain text.
Not only this slows down the mdoc(7) processing significantly, but it also
has an undesired (in this case) effect of disabling hyphenation within the

ee2bf73496 1) Minor nits in the usage message from bde. I took out the hard tabs and
used spaces to align the second line under the program name.
2) Cache uid after call to setuid(getuid()) so we don't waste a system call
   for each packet with a call to getuid for the -v case.
3) Update manual to reflect new restriction on -l from last delta.

3) Don't print all replies unless verbose and root (from idea in
   OpenBSD ping.c 1.10 and 1.11) to avoid leaking information available

Turn this behavior off using '-Q'.  This makes '-v' useless other than as

original packet (mostly byte order problems).
