SRP ciphersuites do not have no authentication. They have authentication
based on SRP. Add new SRP authentication flag and cipher string.

For DTLS we might need to retransmit messages from the previous session
so keep a copy of write context in DTLS retransmission buffers instead
of replacing it after sending CCS. CVE-2013-6450.
We have to use EVP in FIPS mode so we can only partially mitigate
timing differences.
Make an extra call to EVP_DigestSignUpdate to hash additonal blocks
to cover any timing differences caused by removal of padding.
This patch makes the decoding of SSLv3 and TLS CBC records constant
time. Without this, a timing side-channel can be used to build a padding
oracle and mount Vaudenay's attack.
This patch also disables the stitched AESNI+SHA mode pending a similar
fix to that code.
In order to be easy to backport, this change is implemented in ssl/,
rather than as a generic AEAD mode. In the future this should be changed
around so that HMAC isn't in ssl/, but crypto/ as FIPS expects.
change the current certificate (in s->cert->key) to the one used and then
SSL_get_certificate and SSL_get_privatekey will automatically work.
Note for 1.0.1 and earlier also includes backport of the function
ssl_get_server_send_pkey.
than client side as we need to keep the handshake record cache frozen when
it contains all the records need to process the certificate verify message.
(backport from HEAD).
Some #include statements were not properly protected. This will go unnoted
on most systems as openssl/comp.h tends to be installed as a system header
file by default but may become visible when cross compiling.
with the appropriate parameters which calls OBJ_bsearch(). A compiler will
typically inline this.
This avoids the need for cmp_xxx variables and fixes unchecked const issues
with CHECKED_PTR_OF()
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).
(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;
