The SHA4 name was not clear with regards to the new SHA-3 standard. So
SHA2 and SHA4 have been renamed to better represent what they are:
SHA256 and SHA512 modules.
More fixes based on the compiler directives -Wcast-qual -Wwrite-strings
-Wmissing-prototypes -Wmissing-declarations. Not everything with regards
to -Wcast-qual has been fixed as some have unwanted consequences for the
rest of the code.
code selection
The base RFC 4279 DHE-PSK ciphersuites are now supported and added.
The SSL code cuts out code not relevant for defined key exchange methods
The ciphersuites parameter in the ssl_session structure changed from
'int *' to 'int *[4]'.
The new function ssl_set_ciphersuite_for_version() sets specific entries
inside this array. ssl_set_ciphersuite() sets all entries to the same
value.

ChangeLog
library/ssl_srv.c
library/ssl_tls.c
A new OID module has been created that contains the main OID searching
functionality based on type-dependent arrays. A base type is used to
contain the basic values (oid_descriptor_t) and that type is extended to
contain type specific information (like a pk_alg_t).
As a result the rsa sign and verify function prototypes have changed. They
now expect a md_type_t identifier instead of the removed RSA_SIG_XXX
defines.
All OID definitions have been moved to oid.h
All OID matching code is in the OID module.
The RSA PKCS#1 functions cleaned up as a result and adapted to use the
MD layer.
The SSL layer cleanup up as a result and adapted to use the MD layer.
The X509 parser cleaned up and matches OIDs in certificates with new
module and adapted to use the MD layer.
The X509 writer cleaned up and adapted to use the MD layer.
Apps and tests modified accordingly
Made all modifications to include Ephemeral Elliptic Curve Diffie
Hellman ciphersuites into the existing SSL/TLS modules. All basic
handling of the ECDHE-ciphersuites (TLS_ECDHE_RSA_WITH_NULL_SHA,
TLS_ECDHE_RSA_WITH_RC4_128_SHA, TLS_ECDHE_RSA_WITH_3DES_EDE_CBC_SHA,
TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA, TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA)
has been included.
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.
process
Single stepping the handshake process allows for better support of
non-blocking network stacks and for getting information from specific
handshake messages if wanted.
- The error codes have been remapped and combining error codes is now done with a PLUS instead of an OR as error codes used are negative.
- Descriptions to all error codes have been added.
- Generation script for error.c has been created to automatically generate error.c from the available error definitions in the headers.
