Don't turn off the regular SIGINFO status information. The use of
the NOKERNINFO flag only marginally de-clutters the output and
has a number of unwanted side effects:
  o The kernel info might be what you want to see
  o ^T is left non-functional if ping is killed non-cleanly
  o "ping -q foo &" gets suspended on tty output

Certain ICMP error replies cause ping to perform a reverse DNS
lookup on an IP address from the packet (such as the IP that sent
a TTL exceeded error). If the DNS lookup takes a long time, ^C will
appear to be ineffective since the SIGINT handler just sets a flag
and returns. Work around this by exiting immediately on receipt of
a second SIGINT when DNS lookups are enabled.

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.

Fix the broken "avoid unaligned data" fix.  The problem is that the builtin
gcc memcpy "knows" about types that are supposed to be actually already
aligned and triggers alignment errors doing the memcpy itself.
"Fix" this by changing it to a bcopy().  In this case, we had:
  struct timeval *tp;
  struct timeval tv1;
  memcpy(&tv1,tp,sizeof(tv1));
.. and since gcc *knows* that a pointer to a timeval is longword aligned
and that tv1 is longword aligned, then it can use an inline that assumes
alignment.  The following works too:
  cp = (char *)tp;
  memcpy(&tv1,cp,sizeof(tv1));
Simply casting (char *)tp  for the memcpy doesn't work. :-(
This affected different 64 bit platforms in different ways and depends
a lot on gcc as well.  I've seen this on alpha and ia64 at least, although
alpha isn't doing it right now.

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.

Fix unaligned access faults on alpha.

This one is strange and goes against my rusty compiler knowledge.

The global declaration

struct sockaddr whereto;

produces for both i386 && alpha:

        .comm   whereto,16,1

which means common storage, byte aligned. Ahem. I though structs
were supposed to be ALDOUBLE always? I mean, w/o pragma packed?

Later on, this address is coerced to:

		to = (struct sockaddr_in *)&whereto;

Up until now, we've been fine on alpha because the address
just ended up aligned to a 4 byte boundary. Lately, though,
it end up as:

0000000120027b0f B whereto

And, tra la, you get unaligned access faults. The solution I picked, in
lieu of understanding what the compiler was doing, is to put whereto
as a union of a sockaddr and sockaddr_in. That's more formally correct
if somewhat awkward looking.

Modify ping so that it increases the send socket buffer size if the

	o use braces to avoid potentially ambiguous else

Note: The fix to natd is potentially functional in nature since I used
the indentation as the right thing rather than the struct semantics.
Someone more familiar with the code should double check me on this one.

When a timeval is stored at the beginning of icmp_data, the fields
are unaligned for access by the alpha, so copy the value to a variable
that is aligned.

When checking the returned data, be careful to avoid confusing the
size of the icmp header with the size of a timeval. On i386 these
are both 8, but on alpha, a timeval is 16 bytes. This means that
a packet sent from an alpha contains 48 bytes of data, not 56 like
on i386.

Add multicast options -I (source interface), -T (set ttl), -L (no loopback).
They were all lowercase in the original, but our ping already uses -i and
-l so I made them all uppercase.

Cleaned up recent SIGINFO changes.

Simplified average calculations.  This also fixes potential overflow errors
and minor rounding inconsistencies (always round to nearest now).

Don't lose more SIGINFOs than necessary.

Print \r at the start of the status message.  This clears the dots that
are sometimes left by ping -f.

Change how SIGINFO is handled -- set a flag (of sig_atomic_t), and check
that flag on every iteration of the loop.  This avoids calling fprintf
inside a signal handler, which is always somewhat icky.

Move the terminal handling code to a later location; this allows
the signal handlers to be set up; it also means that a failed name lookup
won't mess up the nokerninfo setting of the tty.

Print out ICMP errors that are responses to our own packets by default.
Turn this behavior off using '-Q'.  This makes '-v' useless other than as
an ICMP-sniffer, which tcpdump is better at anyway.

Print out another couple of ICMP messages, and fix the printing of the
original packet (mostly byte order problems).

Limit the risk of `buf' overrun in ping.c when printing hostnames.

Note, this is not really a security risk, because the buffer in question
is a static variable in the data segment and not on the stack, and hence
cannot subert the flow of execution in any way.  About the worst case was
that if you pinged a long hostname, ping could coredump.

In past releases of FreeBSD, I have used the exit status of "ping" to
determine whether a connection to a given machine is up or not.

In FreeBSD 2.0 (and therefore, I assume, BSD 4.4) the exit code of ping
is always zero, even if no packets were received.

I would like to propose the following change to /usr/src/sbin/ping/ping.c
to restore this useful behaviour:
