Subject: [PATCH 2/3] ipv4: Don't use ufo handling on later transformed packets
Date: Thu, 30 Jun 2011 11:19:32 +0200 [thread overview]
Message-ID: <20110630091932.GC13201@secunet.com> (raw)
In-Reply-To: <20110630091820.GB13201@secunet.com>
We might call ip_ufo_append_data() for packets that will be IPsec
transformed later. This function should be used just for real
udp packets. So we check for rt->dst.header_len which is only
nonzero on IPsec handling and call ip_ufo_append_data() just
if rt->dst.header_len is zero.
