8659dc73f4 Reencode certificates in X509_sign_ctx. 
Reencode certificates in X509_sign_ctx as well as X509_sign.

This was causing a problem in the x509 application when it modified an
existing certificate.

07464787a8 crypto/modes/modes_lcl.h: let STRICT_ALIGNMENT be on ARMv7. 
While ARMv7 in general is capable of unaligned access, not all instructions
actually are. And trouble is that compiler doesn't seem to differentiate
those capable and incapable of unaligned access. Side effect is that kernel
goes into endless loop retrying same instruction triggering unaligned trap.
Problem was observed in xts128.c and ccm128.c modules. It's possible to
resolve it by using (volatile u32*) casts, but letting STRICT_ALIGNMENT
be feels more appropriate.

4e5b9645e8 Make binary curve ASN.1 work in FIPS mode. 
Don't check for binary curves by checking methods: the values will
be different in FIPS mode as they are redirected to the validated module
version.

e1dee801b9 Add function CMS_RecipientInfo_encrypt 
Add CMS_RecipientInfo_encrypt: this function encrypts an existing content
encryption key to match the key in the RecipientInfo structure: this is
useful if a new recpient is added to and existing enveloped data structure.

Add documentation.

fb0a59cc58 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.

f5cd3561ba 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.
