[PATCH 2.6.26-rc3] xfrm: Installing NULL encryption IPSec SAs fails

From: Martin Willi
Date: Wed May 21 2008 - 13:24:17 EST


ïInstalling NULL encryption IPSec SAs works using the .compat name
"cipher_null", but fails with the .name "ecp(cipher_null)" due the
missing check in key length verification.
