24b2806097 Move CRYPTO_memcmp to o_init.c when compiling with fips: cryptlib.o
is in the fips module for fips capable builds.

35a65e814b Make CBC decoding constant time.
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.

2708813166 Add and use a constant-time memcmp.
This change adds CRYPTO_memcmp, which compares two vectors of bytes in
an amount of time that's independent of their contents. It also changes
several MAC compares in the code to use this over the standard memcmp,
which may leak information about the size of a matching prefix.

8d038a08fb The fix for CVE-2012-2110 did not take into account that the
'len' argument to BUF_MEM_grow and BUF_MEM_grow_clean is an

rejecting negative len parameter.
