b8dfde2a36 Remove the DTLS1_BAD_VER thing from 0.9.9-dev. It is present in 0.9.8
but has been omitted from HEAD (0.9.9), see commit

570006f3a2 Half of the commit for 0.9.8 as the bitmap handling has changed.
(Firstly... ommitted)

Secondly, it wasn't even _dropping_ the offending packets, in the
non-blocking case. It was just returning garbage instead.

7e7af0bc51 When the underlying BIO_write() fails to send a datagram, we leave the
offending record queued as 'pending'. The DTLS code doesn't expect this,
and we end up hitting an OPENSSL_assert() in do_dtls1_write().

The simple fix is just _not_ to leave it queued. In DTLS, dropping
packets is perfectly acceptable -- and even preferable. If we wanted a
service with retries and guaranteed delivery, we'd be using TCP.

4c3296960d Remove the dual-callback scheme for numeric and pointer thread IDs,
deprecate the original (numeric-only) scheme, and replace with the
CRYPTO_THREADID object. This hides the platform-specifics and should reduce
the possibility for programming errors (where failing to explicitly check
both thread ID forms could create subtle, platform-specific bugs).

Thanks to Bodo, for invaluable review and feedback.

Geoff Thorpe
f7ccba3edf There was a need to support thread ID types that couldn't be reliably cast
to 'unsigned long' (ie. odd platforms/compilers), so a pointer-typed
version was added but it required portable code to check *both* modes to
determine equality. This commit maintains the availability of both thread
ID types, but deprecates the type-specific accessor APIs that invoke the
callbacks - instead a single type-independent API is used.  This simplifies
software that calls into this interface, and should also make it less
error-prone - as forgetting to call and compare *both* thread ID accessors
could have led to hard-to-debug/infrequent bugs (that might only affect
certain platforms or thread implementations). As the CHANGES note says,
there were corresponding deprecations and replacements in the
thread-related functions for BN_BLINDING and ERR too.

0e1dba934f 1. Changes for s_client.c to make it return non-zero exit code in case
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

52b8dad8ec Reorganize the data used for SSL ciphersuite pattern matching.
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.

cbb92dfaf0 Fixes for the following claims:
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.

d1acb9b44f Further change pq_compat.h to generate the flag macros PQ_64BIT_IS_INTEGER
and PQ_64BIT_IS_BIGNUM with the values 0 (for false) and 1 (for true),
depending on which is true.  Use those flags everywhere else to provide
the correct implementation for handling certain operations in q PQ_64BIT.

188b05792f pqueue and dtls uses 64-bit values. Unfortunately, OpenSSL doesn't
have a uniform representation for those over all architectures, so a
little bit of hackery is needed.

fbeaa3c47d Update util/ck_errf.pl script, and have it run automatically
during "make errors" and thus during "make update".

Fix lots of bugs that util/ck_errf.pl can detect automatically.
Various others of these are still left to fix; that's why
"make update" will complain loudly when run now.
