Joey Hess	4603713b4e	avoid using htonl ... It got removed from network-3.0.0.0 and nothing in the haskell ecosystem currently provides it (which seems it ought to be fixed). Tested new code on both little-endian and big-endian with: ghci> hostAddressToTuple $ fromJust $ embeddedIpv4 (0,0,0,0,0,0xffff,0x7f00,1) (127,0,0,1)	2019-02-19 12:17:20 -04:00
Joey Hess	3976b89116	fix license date ... I wrote this this year	2018-06-22 10:25:53 -04:00
Joey Hess	43bf219a3c	added makeAddressMatcher ... Would be nice to add CIDR notation to this, but this is the minimal thing needed for the security fix. This commit was sponsored by Ewen McNeill on Patreon.	2018-06-17 13:29:15 -04:00
Joey Hess	014a3fef34	added isPrivateAddress and isLoopbackAddress ... For use in a security boundary enforcement. Based on https://en.wikipedia.org/wiki/Reserved_IP_addresses Including supporting IPv4 addresses embedded in IPv6 addresses. Because while RFC6052 3.1 says "Address translators MUST NOT translate packets in which an address is composed of the Well-Known Prefix and a non- global IPv4 address; they MUST drop these packets", I don't want to trust that implementations get that right when enforcing a security boundary.
