From bcb576e1a7f16853cc965de5516c5afbbfeec8a9 Mon Sep 17 00:00:00 2001 From: Maciej Żenczykowski Date: Thu, 18 Jul 2019 23:30:03 -0700 Subject: UPSTREAM: net-ipv6-ndisc: add support for RFC7710 RA Captive Portal Identifier MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This is trivial since we already have support for the entirely identical (from the kernel's point of view) RDNSS and DNSSL that also contain opaque data that needs to be passed down to userspace. As specified in RFC7710, Captive Portal option contains a URL. 8-bit identifier of the option type as assigned by the IANA is 37. This option should also be treated as userland. Hence, treat ND option 37 as userland (Captive Portal support) See: https://tools.ietf.org/html/rfc7710 https://www.iana.org/assignments/icmpv6-parameters/icmpv6-parameters.xhtml Fixes: e35f30c131a56 Signed-off-by: Maciej Żenczykowski Cc: Lorenzo Colitti Cc: Remin Nguyen Van Cc: Alexey I.
