More robust fix and workaround for PR#1949. Don't try to work out if there

work in SSLv3: initial handshake has no extensions but includes MCSV, if
server indicates RI support then renegotiation handshakes include RI.
NB: current MCSV value is bogus for testing only, will be updated when we
have an official value.
Change mismatch alerts to handshake_failure as required by spec.
Also have some debugging fprintfs so we can clearly see what is going on
if OPENSSL_RI_DEBUG is set.

of handshake failure
2. Changes to x509_certificate_type function (crypto/x509/x509type.c) to
make it recognize GOST certificates as EVP_PKT_SIGN|EVP_PKT_EXCH
(required for s3_srvr to accept GOST client certificates).
3. Changes to EVP
- adding of function EVP_PKEY_CTX_get0_peerkey
- Make function EVP_PKEY_derive_set_peerkey work for context with
ENCRYPT operation, because we use peerkey field in the context to
pass non-ephemeral secret key to GOST encrypt operation.
- added EVP_PKEY_CTRL_SET_IV control command. It is really
GOST-specific, but it is used in SSL code, so it has to go
in some header file, available during libssl compilation
4. Fix to HMAC to avoid call of OPENSSL_cleanse on undefined data
5. Include des.h if KSSL_DEBUG is defined into some libssl files, to
make debugging output which depends on constants defined there, work
and other KSSL_DEBUG output fixes
6. Declaration of real GOST ciphersuites, two authentication methods
SSL_aGOST94 and SSL_aGOST2001 and one key exchange method SSL_kGOST
7. Implementation of these methods.
8. Support for sending unsolicited serverhello extension if GOST
ciphersuite is selected. It is require for interoperability with
CryptoPro CSP 3.0 and 3.6 and controlled by
SSL_OP_CRYPTOPRO_TLSEXT_BUG constant.
This constant is added to SSL_OP_ALL, because it does nothing, if
non-GOST ciphersuite is selected, and all implementation of GOST
include compatibility with CryptoPro.
9. Support for CertificateVerify message without length field. It is
another CryptoPro bug, but support is made unconditional, because it
does no harm for draft-conforming implementation.
10. In tls1_mac extra copy of stream mac context is no more done.
When I've written currently commited code I haven't read
EVP_DigestSignFinal manual carefully enough and haven't noticed that
it does an internal digest ctx copying.
This implementation was tested against
1. CryptoPro CSP 3.6 client and server
2. Cryptopro CSP 3.0 server

ciphersuite selection code in HEAD
Submitted by: Victor Duchovni
|
|
This change resolves a number of problems and obviates multiple kludges.
A new feature is that you can now say "AES256" or "AES128" (not just
"AES", which enables both).
In some cases the ciphersuite list generated from a given string is
affected by this change. I hope this is just in those cases where the
previous behaviour did not make sense.

1) Certificate Message with no certs
OpenSSL implementation sends the Certificate message during SSL
handshake, however as per the specification, these have been omitted.
-- RFC 2712 --
CertificateRequest, and the ServerKeyExchange shown in Figure 1
will be omitted since authentication and the establishment of a
master secret will be done using the client's Kerberos credentials
for the TLS server. The client's certificate will be omitted for
the same reason.
-- RFC 2712 --
3) Pre-master secret Protocol version
The pre-master secret generated by OpenSSL does not have the correct
client version.
RFC 2712 says, if the Kerberos option is selected, the pre-master
secret structure is the same as that used in the RSA case.
TLS specification defines pre-master secret as:
struct {
ProtocolVersion client_version;
opaque random[46];
} PreMasterSecret;
where client_version is the latest protocol version supported by the
client
The pre-master secret generated by OpenSSL does not have the correct
client version. The implementation does not update the first 2 bytes
of random secret for Kerberos Cipher suites. At the server-end, the
client version from the pre-master secret is not validated.
PR: 1336

Also, change the default ciphersuite to give some prefererence to
ciphersuites with forwared secrecy (rather than using a random order).
