Package: src:linux Version: 3.2.32-1 Severity: normal Tags: patch ipv6 Hi, e35f30c131a562bafd069820a6983fd4023e606e landed in 3.5, adding support to pass along DNSSL information (RFC 6106) from IPv6 Router Advertisements to userspace programs via netlink. network-manager will then use this information to add search list information to /etc/resolv.conf. The current wheezy kernel does not support this. Could this patch be included? It's very small, too, because all it does is flagging the option to be passed through. The current network-manager in wheezy already supports the option. commit e35f30c131a562bafd069820a6983fd4023e606e Author: Alexey I. Froloff <raorn@raorn.name> Date: Fri Apr 6 05:50:58 2012 +0000 Treat ND option 31 as userland (DNSSL support) As specified in RFC6106, DNSSL option contains one or more domain names of DNS suffixes. 8-bit identifier of the DNSSL option type as assigned by the IANA is 31. This option should also be treated as userland. Signed-off-by: Alexey I. Froloff <raorn@raorn.name> Signed-off-by: David S.
