Removed prior audit proof logic - audit proof support was implemented using the generic TLS extension API
Tests exercising the new supplemental data registration and callback api can be found in ssltest.c.
Implemented changes to s_server and s_client to exercise supplemental data callbacks via the -auth argument, as well as additional flags to exercise supplemental data being sent only during renegotiation.
This change adds support for ALPN[1] in OpenSSL. ALPN is the IETF
blessed version of NPN and we'll be supporting both ALPN and NPN for
some time yet.

[A part of this change affecting ssl/s3_lib.c was accidentally commited
separately, together with a compilation fix for that file;
see s3_lib.c CVS revision 1.133 (http://cvs.openssl.org/chngview?cn=19855).]
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.
knock-on work than expected - they've been extracted into a patch
series that can be completed elsewhere, or in a different branch,
before merging back to HEAD.
Also, get rid of compile-time switch OPENSSL_NO_RELEASE_BUFFERS
because it was rather pointless (the new behavior has to be explicitly
requested by setting SSL_MODE_RELEASE_BUFFERS anyway).
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
(draft-rescorla-tls-opaque-prf-input-00.txt), and do some cleanups and
bugfixes on the way. In particular, this fixes the buffer bounds
checks in ssl_add_clienthello_tlsext() and in ssl_add_serverhello_tlsext().
Note that the opaque PRF Input TLS extension is not compiled by default;
see CHANGES.
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.

relates to SSL_CTX flags and the use of "external" session caching. The
existing flag, "SSL_SESS_CACHE_NO_INTERNAL_LOOKUP" remains but is
supplemented with a complimentary flag, "SSL_SESS_CACHE_NO_INTERNAL_STORE".
The bitwise OR of the two flags is also defined as
"SSL_SESS_CACHE_NO_INTERNAL" and is the flag that should be used by most
applications wanting to implement session caching *entirely* by its own
provided callbacks. As the documented behaviour contradicted actual
behaviour up until recently, and since that point behaviour has itself been
inconsistent anyway, this change should not introduce any compatibility
problems. I've adjusted the relevant documentation to elaborate about how
this works.
Kudos to "Nadav Har'El" <nyh@math.technion.ac.il> for diagnosing these
anomalies and testing this patch for correctness.

des_old.h redefines crypt:
#define crypt(b,s)\
DES_crypt((b),(s))
This scheme leads to failure, if header files with the OS's true definition
of crypt() are processed _after_ des_old.h was processed. This is e.g. the
case on HP-UX with unistd.h.
As evp.h now again includes des.h (which includes des_old.h), this problem
only came up after this modification.
Solution: move header files (indirectly) including e_os.h before the header
files (indirectly) including evp.h.
