Subject: IPV6_RTHDR with a type-0 routing header
Date: Thu, 20 Aug 2009 13:11:52 +0200	[thread overview]
Message-ID: <20090820111152.GA20295@uio.no> (raw)

Hi,

I've tried attaching a type-0 routing header to my IPv6 packets with
setsockopt(..., IPV6_RTHDR, ...), but the kernel just returns EINVAL.
looking at the source, it seems it simply refuses anything that's not type-2;
should that really be right? I found the following commit:

  http://kerneltrap.org/mailarchive/linux-netdev/2008/11/11/4064594

However, it only seems to change EPERM into EINVAL. I don't see any
reasonable explanation why it should not be simply success; in fact, RFC 3452
only seems to talk about using type-0 headers with this option.

Any ideas?
