From 63eb1f4c6ef8c1bb68afbfc5fba8762d50c1a0a8 Mon Sep 17 00:00:00 2001 From: Rob Crittenden <rcritten@redhat.com> Date: Wed, 17 Jun 2015 11:12:40 -0400 Subject: [PATCH] Fix logical AND support in OpenSSL cipher compatibility The + operator didn't perform properly at all. It is supposed to be used either for logical AND to combine two cipher suites or to move ciphers to the end of the list. Given that NSS doesn't support cipher ordering + is a no-op in this case. Also add in a slew of missing aliases: kRSA, aRSA, EDH, ECDH, kECDHe, kECDHr, kEECDH, aECDH, aNULL, AESGCM, AES128, AES256, CAMELLIA, CAMELLIA128, CAMELLIA256. Fix the definition of TLSv1.2. Define some ciphers as unimplemented in NSS. Renumber the mask/protocol/strength values to ensure uniqueness. Replace the existing cipher test to one that compares the output of the NSS-generated cipher string with the openssl generated string. There are a lot of restrictions on the openssl string since so much isn't either implemented or needed for mod_nss. Add a new openssl-compatible cipher request test to the server tests. --- nss_engine_cipher.c | 196 +++++++++++++++++++++++++++++++------- nss_engine_cipher.h | 61 ++++++------ test/createinstance.sh | 1 + test/suite1.tmpl | 6 ++ test/test.py | 6 ++ test/test_cipher.py | 254 ++++++++++++++++++++++++++++++++----------------- test_cipher.c | 32 +++++-- 7 files changed, 401 insertions(+), 155 deletions(-) diff --git a/nss_engine_cipher.c b/nss_engine_cipher.c index 9110d57..37ef338 100644 --- a/nss_engine_cipher.c +++ b/nss_engine_cipher.c @@ -29,10 +29,11 @@ cipher_properties ciphers_def[ciphernum] = {"rsa_rc4_128_md5", TLS_RSA_WITH_RC4_128_MD5, "RC4-MD5", SSL_kRSA|SSL_aRSA|SSL_RC4|SSL_MD5, SSLV3, SSL_MEDIUM, 128, 128}, {"rsa_rc4_128_sha", TLS_RSA_WITH_RC4_128_SHA, "RC4-SHA", SSL_kRSA|SSL_aRSA|SSL_RC4|SSL_SHA1, SSLV3, SSL_MEDIUM, 128, 128}, {"rsa_rc2_40_md5", TLS_RSA_EXPORT_WITH_RC2_CBC_40_MD5, "EXP-RC2-CBC-MD5", SSL_kRSA|SSL_aRSA|SSL_RC2|SSL_MD5, SSLV3, SSL_EXPORT40, 40, 128}, + /* TLS_RSA_EXPORT_WITH_DES40_CBC_SHA not implemented 0x0008 */ {"rsa_des_sha", TLS_RSA_WITH_DES_CBC_SHA, "DES-CBC-SHA", SSL_kRSA|SSL_aRSA|SSL_DES|SSL_SHA1, SSLV3, SSL_LOW, 56, 56}, - {"rsa_3des_sha", TLS_RSA_WITH_3DES_EDE_CBC_SHA, "DES-CBC3-SHA", SSL_kRSA|SSL_aRSA|SSL_3DES|SSL_SHA1, SSLV3, SSL_HIGH, 112, 168}, + {"rsa_3des_sha", TLS_RSA_WITH_3DES_EDE_CBC_SHA, "DES-CBC3-SHA", SSL_kRSA|SSL_aRSA|SSL_3DES|SSL_SHA1, SSLV3, SSL_HIGH, 168, 168}, {"rsa_aes_128_sha", TLS_RSA_WITH_AES_128_CBC_SHA, "AES128-SHA", SSL_kRSA|SSL_aRSA|SSL_AES128|SSL_SHA1, TLSV1, SSL_HIGH, 128, 128}, - {"rsa_aes_256_sha", TLS_RSA_WITH_AES_256_CBC_SHA, "AES256-SHA256", SSL_kRSA|SSL_aRSA|SSL_AES256|SSL_SHA1, TLSV1, SSL_HIGH, 256, 256}, + {"rsa_aes_256_sha", TLS_RSA_WITH_AES_256_CBC_SHA, "AES256-SHA", SSL_kRSA|SSL_aRSA|SSL_AES256|SSL_SHA1, TLSV1, SSL_HIGH, 256, 256}, {"null_sha_256", TLS_RSA_WITH_NULL_SHA256, "NULL-SHA256", SSL_kRSA|SSL_aRSA|SSL_eNULL|SSL_SHA256, TLSV1_2, SSL_STRONG_NONE, 0, 0}, {"aes_128_sha_256", TLS_RSA_WITH_AES_128_CBC_SHA256, "AES128-SHA256", SSL_kRSA|SSL_aRSA|SSL_AES128|SSL_SHA256, TLSV1_2, SSL_HIGH, 128, 128}, {"aes_256_sha_256", TLS_RSA_WITH_AES_256_CBC_SHA256, "AES256-SHA256", SSL_kRSA|SSL_aRSA|SSL_AES256|SSL_SHA256, TLSV1_2, SSL_HIGH, 256, 256}, @@ -73,9 +74,25 @@ cipher_properties ciphers_def[ciphernum] = {"ecdhe_rsa_aes_128_sha_256", TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA256, "ECDHE-RSA-AES128-SHA256", SSL_kEECDH|SSL_aRSA|SSL_AES128|SSL_SHA256, TLSV1_2, SSL_HIGH, 128, 128}, {"ecdhe_ecdsa_aes_128_gcm_sha_256", TLS_ECDHE_ECDSA_WITH_AES_128_GCM_SHA256, "ECDHE-ECDSA-AES128-GCM-SHA256", SSL_kEECDH|SSL_aECDSA|SSL_AES128GCM|SSL_AEAD, TLSV1_2, SSL_HIGH, 128, 128}, {"ecdhe_rsa_aes_128_gcm_sha_256", TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256, "ECDHE-RSA-AES128-GCM-SHA256", SSL_kEECDH|SSL_aRSA|SSL_AES128GCM|SSL_AEAD, TLSV1_2, SSL_HIGH, 128, 128}, + /* TLS_ECDH_ECDSA_WITH_AES_128_GCM_SHA256 is not implemented */ + /* TLS_ECDH_ECDSA_WITH_AES_128_CBC_SHA256 is not implemented */ + /* TLS_ECDH_RSA_WITH_AES_128_GCM_SHA256 is not implemented */ + /* TLS_ECDH_RSA_WITH_AES_128_CBC_SHA256 is not implemented */ #endif }; + +/* Some ciphers are optionally enabled in OpenSSL.
