1bd3ae826c Added md_process() to MD layer for generic internal access to hash
process functions

Access to process functions is needed to reduce possible timing attacks
on SSL MAC checks. As SSL is set to move to using the dynamic MD layer,
the MD layer needs access to these process functions as well.

e81beda60f The SSL session cache module (ssl_cache) now also retains peer_cert information (not the entire chain)
The real peer certificate is copied into a x509_buf in the
ssl_cache_entry and reinstated upon cache retrieval. The information
about the rest of the certificate chain is lost in the process.

As the handshake (and certificate verification) has already been
performed, no issue is foreseen.

78a8c71993 Re-added support for parsing and handling SSLv2 Client Hello messages
If the define POLARSSL_SSL_SRV_SUPPORT_SSLV2_CLIENT_HELLO is enabled,
the SSL Server module can handle the old SSLv2 Client Hello messages.

It has been updated to deny SSLv2 Client Hello messages during
renegotiation.

b386913f8b Split up the RSA PKCS#1 encrypt, decrypt, sign and verify functions
Split rsa_pkcs1_encrypt() into rsa_rsaes_oaep_encrypt() and
rsa_rsaes_pkcs1_v15_encrypt()
Split rsa_pkcs1_decrypt() into rsa_rsaes_oaep_decrypt() and
rsa_rsaes_pkcs1_v15_decrypt()
Split rsa_pkcs1_sign() into rsa_rsassa_pss_sign() and
rsa_rsassa_pkcs1_v15_sign()
Split rsa_pkcs1_verify() into rsa_rsassa_pss_verify() and
rsa_rsassa_pkcs1_v15_verify()

The original functions exist as generic wrappers to these functions.

3d2dc0f8e5 Corrected GCM counter incrementation to use only 32-bits instead of 128-bits
Using 32-bits has the possibility to overwrite the IV in the first 12
bytes of the Y variable.

e47b34bdc8 Removed further timing differences during SSL message decryption in ssl_decrypt_buf()
New padding checking is unbiased on correct or incorrect padding and
has no branch prediction timing differences.

The additional MAC checks further straighten out the timing differences.
