ec1b761489 Support multiple cyclic groups for smaller subnets 
We will choose the first one in the list that is large enough to support
the number of hosts chosen. This speeds up scanning small networks considerably:
e.g. /16s can be scanned in <200ms (+ cooldown)

8ecbd038b5 Adding radix support to constraints 
This allows us to lookup an index -> ip address much faster
(16 seconds for ~3.7 billion addresses with sparse blacklist,
vs 65 sec before radix array).

Setting the PREFIX_LEN to /20, as this appears to give a good tradeoff
between radix population time (<1ms), runtime (16s), and memory footprint (4MB).

952df21a1f Changing 192.18.0.0/15 to 198.18.0.0/15 in default blacklist. 
Reported by David Fifield: The network 192.18.0.0/15 is typoed in RFC 2544;
it should be 198.18.0.0/15. The erratum is here:

Eric
754e2dc1f7 Add icmp_responder to UDP fieldset 
icmp_responder is the source address of the DEST_UNREACH ICMP
packet, which is not necessarily the same as the saddr (e.g.
NETWORK_UNREACH)

d694fe69a6 UDP probe module updates saddr fieldset 
ICMP responses (e.g. DEST_UNREACH) to UDP probes (generally)
contain the IP/UDP packet that ellicited the response, though
they do not have to come from the host we sent them to (e.g.
NETWORK_UNREACH). We will "correct" this by switching the saddr
fieldset to be the host we WOULD have received a response from

ee9593938b Move make_ip_str to probe_modules/packet.c

Eric
e458982892 Add fs_modify_word to fieldset 
You may modify an existing word to be a different value;
useful in UDP module for ICMP unreachable responses, so
we can update the "source" address

c185f6b0a4 Fake an ethernet header rather than expose vulns 
There is probably a slight performance hit, but if you're
scanning with ZMap through a VPN, you probably don't care THAT
much about performance anyway...(also we only add a memcpy for
all accepted packets)

2972bbefdc Add --vpn (-X) flag to support sending IP pkts 
When a user specifies a `-i tun0` flag for a VPN interface,
this interface expects raw IP packets, not ethernet frames.
The --vpn option allows you to send only IP packets to the
specified interface, and also performs some hacks on the receive
end to ensure we can process the results.

TODO: malloc a fake ethernet header for probe_modules.process_packet
(or better yet, make process_packet always take an IP packet, they
all seem to be implicitly doing that anyway).
