But some of the code currently relies on an IV generator to be present. So we don't have to change that code and handle IV size == 0 specially we use the new NULL IV generator, which handles this transparently to the existing code. Before 3c81cb6fc322 ("aead: Create AEAD using traditional transforms with an explicit IV generator") iv_gen_rand_t was used for NULL encryption, which would work too but this way it's clearer. --- src/libstrongswan/crypto/iv/iv_gen.c | 5 +++++ 1 file changed, 5 insertions(+) diff --git a/src/libstrongswan/crypto/iv/iv_gen.c b/src/libstrongswan/crypto/iv/iv_gen.c index 7d6570a74..c70627723 100644 --- a/src/libstrongswan/crypto/iv/iv_gen.c +++ b/src/libstrongswan/crypto/iv/iv_gen.c @@ -1,4 +1,7 @@ /* + * Copyright (C) 2015 Tobias Brunner + * Hochschule fuer Technik Rapperswil + * * Copyright (C) 2015 Martin Willi * Copyright (C) 2015 revosec AG * @@ -16,6 +19,7 @@ #include "iv_gen.h" #include "iv_gen_rand.h" #include "iv_gen_seq.h" +#include "iv_gen_null.h" /** * See header. @@ -52,6 +56,7 @@ iv_gen_t* iv_gen_create_for_alg(encryption_algorithm_t alg) case ENCR_NULL_AUTH_AES_GMAC: return iv_gen_seq_create(); case ENCR_NULL: + return iv_gen_null_create(); case ENCR_UNDEFINED: case ENCR_DES_ECB: case ENCR_DES_IV32: From 17816515d26fb8b983c35641caaaf82a08cb5962 Mon Sep 17 00:00:00 2001 From: Tobias Brunner Date: Fri, 23 Oct 2015 14:47:54 +0200 Subject: [PATCH 3/3] testing: Add libipsec/net2net-null scenario --- .../libipsec/net2net-null/description.txt | 11 + .../tests/libipsec/net2net-null/evaltest.dat | 11 + .../net2net-null/hosts/moon/etc/ipsec.conf | 24 + .../hosts/moon/etc/strongswan.conf | 6 + .../net2net-null/hosts/moon/etc/updown | 566 ++++++++++++++++++ .../net2net-null/hosts/sun/etc/ipsec.conf | 24 + .../hosts/sun/etc/strongswan.conf | 6 + .../net2net-null/hosts/sun/etc/updown | 566 ++++++++++++++++++ .../tests/libipsec/net2net-null/posttest.dat | 4 + .../tests/libipsec/net2net-null/pretest.dat | 6 + testing/tests/libipsec/net2net-null/test.conf | 21 + 11 files changed, 1245 insertions(+) create mode 100644 testing/tests/libipsec/net2net-null/description.txt create mode 100644 testing/tests/libipsec/net2net-null/evaltest.dat create mode 100644 testing/tests/libipsec/net2net-null/hosts/moon/etc/ipsec.conf create mode 100644 testing/tests/libipsec/net2net-null/hosts/moon/etc/strongswan.conf create mode 100755 testing/tests/libipsec/net2net-null/hosts/moon/etc/updown create mode 100644 testing/tests/libipsec/net2net-null/hosts/sun/etc/ipsec.conf create mode 100644 testing/tests/libipsec/net2net-null/hosts/sun/etc/strongswan.conf create mode 100755 testing/tests/libipsec/net2net-null/hosts/sun/etc/updown create mode 100644 testing/tests/libipsec/net2net-null/posttest.dat create mode 100644 testing/tests/libipsec/net2net-null/pretest.dat create mode 100644 testing/tests/libipsec/net2net-null/test.conf diff --git a/testing/tests/libipsec/net2net-null/description.txt b/testing/tests/libipsec/net2net-null/description.txt new file mode 100644 index 000000000..d8f019d36 --- /dev/null +++ b/testing/tests/libipsec/net2net-null/description.txt @@ -0,0 +1,11 @@ +A connection between the subnets behind the gateways moon and sun is set up. +The authentication is based on X.509 certificates and the kernel-libipsec +plugin is used for userland IPsec ESP encryption.
