File 0153-inet.xml-fix-invalid-IPv4-mapped-address-examples.patch of Package erlang
From df75dcf7287cb0c0ffd4dc7f253161eb3f3779c3 Mon Sep 17 00:00:00 2001 From: Kenji Rikitake <kenji.rikitake@acm.org> Date: Thu, 4 May 2017 19:45:30 +0900 Subject: [PATCH] inet.xml: fix invalid IPv4-mapped-address examples * IPv6 address FFFF::192.168.42.2 is an invalid form as an IPv4-mapped address. This should be fixed as ::FFFF:192.168.42.2. The assigned address block is ::ffff:0:0/96. See RFC6890 Table 20 in the Section 2.2.2 for the further details. And for this IPv4-mapped address use *only*, the 32bit LSB of the IPv6 address can be written with the respective IPv4 address. See RFC4291 Section 2.2 Form 3 for the further details. --- lib/kernel/doc/src/inet.xml | 8 ++++---- 1 file changed, 4 insertions(+), 4 deletions(-) diff --git a/lib/kernel/doc/src/inet.xml b/lib/kernel/doc/src/inet.xml index 947e4d456..b9f5f87ef 100644 --- a/lib/kernel/doc/src/inet.xml +++ b/lib/kernel/doc/src/inet.xml @@ -75,8 +75,8 @@ Address ip_address() ------- ------------ ::1 {0,0,0,0,0,0,0,1} ::192.168.42.2 {0,0,0,0,0,0,(192 bsl 8) bor 168,(42 bsl 8) bor 2} -FFFF::192.168.42.2 - {16#FFFF,0,0,0,0,0,(192 bsl 8) bor 168,(42 bsl 8) bor 2} +::FFFF:192.168.42.2 + {0,0,0,0,0,16#FFFF,(192 bsl 8) bor 168,(42 bsl 8) bor 2} 3ffe:b80:1f8d:2:204:acff:fe17:bf38 {16#3ffe,16#b80,16#1f8d,16#2,16#204,16#acff,16#fe17,16#bf38} fe80::204:acff:fe17:bf38 @@ -87,8 +87,8 @@ fe80::204:acff:fe17:bf38 <pre> 1> <input>inet:parse_address("192.168.42.2").</input> {ok,{192,168,42,2}} -2> <input>inet:parse_address("FFFF::192.168.42.2").</input> -{ok,{65535,0,0,0,0,0,49320,10754}}</pre> +2> <input>inet:parse_address("::FFFF:192.168.42.2").</input> +{ok,{0,0,0,0,0,65535,49320,10754}}</pre> </description> <datatypes> -- 2.13.0
