[PATCH] IPv6 routing headers issue
From: Thomas Graf <email@example.com>
Backport of the fix to disallow RH0 by default. The original
upstream patch introduces a configuration option which breaks
kABI as it extends a struct which is embeded into another
public structure and is thus not acceptable as-is. Therefore
the decision has been made to disallow routing header type 0
in gernal for now, a configuration option to enable certain
uses again can be added later when more time for testing is
available without the pressure of a security issue. Also the
code is kept close to the upstream version to ease a possible
backporting of Mobile IPv6 which will require receiving routing
header type 2.

[IPV6]: Disallow RH0 by default.
A security issue is emerging. Disallow Routing Header Type 0 by
as we have been doing for IPv4.
Note: We allow RH2 by default because it is harmless.
