Message-Id: <E1IhnTp-0003GE-00@gondolin.me.apana.org.au> Date: Tue, 16 Oct 2007 22:33:09 +0800 From: Herbert Xu <herbert@...dor.apana.org.au> To: "David S. Miller" <davem@...emloft.net>, netdev@...r.kernel.org, Patrick McHardy <kaber@...sh.net>, Herbert Xu <herbert@...dor.apana.org.au> Subject: [PATCH 1/12] [IPSEC]: Fix pure tunnel modes involving IPv6 [IPSEC]: Fix pure tunnel modes involving IPv6 I noticed that my recent patch broke 6-on-4 pure IPsec tunnels (the ones that are only used for incompressible IPsec packets). Subsequent reviews show that I broke 6-on-6 pure tunnels more than three years ago and nobody ever noticed. I suppose every must be testing 6-on-6 IPComp with large pings which are very compressible :) This patch fixes both cases.
