SubjectRe: [PATCH 1/1] ipv6: fix header length calculation in ip6_append_data()
From: Romain KUNTZ <>
Date: Wed, 16 Jan 2013 23:47:40 +0100

> Commit 299b0767 (ipv6: Fix IPsec slowpath fragmentation problem)
> has introduced a error in the header length calculation that
> provokes corrupted packets when non-fragmentable extensions
> headers (Destination Option or Routing Header Type 2) are used.
> rt->rt6i_nfheader_len is the length of the non-fragmentable
> extension header, and it should be substracted to
> rt->dst.header_len, and not to exthdrlen, as it was done before
> commit 299b0767.
> This patch reverts to the original and correct behavior. It has
> been successfully tested with and without IPsec on packets
> that include non-fragmentable extensions headers.
