From 8be3f306338e27b3fa3ad3bfb75f822d038909a5 Mon Sep 17 00:00:00 2001 From: Carl Dong Date: Thu, 28 Mar 2019 15:21:31 -0400 Subject: netaddress: Update CNetAddr for ORCHIDv2 The original ORCHID prefix was deprecated as of 2014-03, the new ORCHIDv2 prefix was allocated by RFC7343 as of 2014-07. We did not consider the original ORCHID prefix routable, and I don't see any reason to consider the new one to be either. --- src/netaddress.cpp | 7 ++++++- src/netaddress.h | 3 ++- src/test/netbase_tests.cpp | 1 + 3 files changed, 9 insertions(+), 2 deletions(-) diff --git a/src/netaddress.cpp b/src/netaddress.cpp index 6ee2d8a4b3..db6c46d12a 100644 --- a/src/netaddress.cpp +++ b/src/netaddress.cpp @@ -204,6 +204,11 @@ bool CNetAddr::IsRFC4843() const return (GetByte(15) == 0x20 && GetByte(14) == 0x01 && GetByte(13) == 0x00 && (GetByte(12) & 0xF0) == 0x10); } +bool CNetAddr::IsRFC7343() const +{ + return (GetByte(15) == 0x20 && GetByte(14) == 0x01 && GetByte(13) == 0x00 && (GetByte(12) & 0xF0) == 0x20); +} + /** * @returns Whether or not this is a dummy address that maps an onion address * into IPv6. @@ -289,7 +294,7 @@ bool CNetAddr::IsValid() const */ bool CNetAddr::IsRoutable() const { - return IsValid() && !(IsRFC1918() || IsRFC2544() || IsRFC3927() || IsRFC4862() || IsRFC6598() || IsRFC5737() || (IsRFC4193() && !IsTor()) || IsRFC4843() || IsLocal() || IsInternal()); + return IsValid() && !(IsRFC1918() || IsRFC2544() || IsRFC3927() || IsRFC4862() || IsRFC6598() || IsRFC5737() || (IsRFC4193() && !IsTor()) || IsRFC4843() || IsRFC7343() || IsLocal() || IsInternal()); } /** diff --git a/src/netaddress.h b/src/netaddress.h index 8230e40606..673eaf8d7b 100644 --- a/src/netaddress.h +++ b/src/netaddress.h @@ -63,7 +63,8 @@ class CNetAddr bool IsRFC3964() const; // IPv6 6to4 tunnelling (2002::/16) bool IsRFC4193() const; // IPv6 unique local (FC00::/7) bool IsRFC4380() const; // IPv6 Teredo tunnelling (2001::/32) - bool IsRFC4843() const; // IPv6 ORCHID (2001:10::/28) + bool IsRFC4843() const; // IPv6 ORCHID (deprecated) (2001:10::/28) + bool IsRFC7343() const; // IPv6 ORCHIDv2 (2001:20::/28) bool IsRFC4862() const; // IPv6 autoconfig (FE80::/64) bool IsRFC6052() const; // IPv6 well-known prefix for IPv4-embedded address (64:FF9B::/96) bool IsRFC6145() const; // IPv6 IPv4-translated address (::FFFF:0:0:0/96) (actually defined in RFC2765) diff --git a/src/test/netbase_tests.cpp b/src/test/netbase_tests.cpp index dd5e3eb6d5..86c0cecbf1 100644 --- a/src/test/netbase_tests.cpp +++ b/src/test/netbase_tests.cpp @@ -59,6 +59,7 @@ BOOST_AUTO_TEST_CASE(netbase_properties) BOOST_CHECK(ResolveIP("FC00::").IsRFC4193()); BOOST_CHECK(ResolveIP("2001::2").IsRFC4380()); BOOST_CHECK(ResolveIP("2001:10::").IsRFC4843()); + BOOST_CHECK(ResolveIP("2001:20::").IsRFC7343()); BOOST_CHECK(ResolveIP("FE80::").IsRFC4862()); BOOST_CHECK(ResolveIP("64:FF9B::").IsRFC6052()); BOOST_CHECK(ResolveIP("FD87:D87E:EB43:edb1:8e4:3588:e546:35ca").IsTor()); -- cgit v1.2.3
