ecb1445ce2 Implement fixed-window exponentiation to mitigate hyper-threading 
timing attacks.

BN_FLG_EXP_CONSTTIME requests this algorithm, and this done by default for
RSA/DSA/DH private key computations unless
RSA_FLAG_NO_EXP_CONSTTIME/DSA_FLAG_NO_EXP_CONSTTIME/
DH_FLAG_NO_EXP_CONSTTIME is set.

bd573ee31a The OPENSSL_NO_ENGINE has small problem: it changes certain structures. That's 
bad, so let's not check OPENSSL_NO_ENGINE in those places.  Fortunately, all
the header files where the problem existed include ossl_typ.h, which makes
a 'forward declaration' of the ENGINE type.

ff90d659e6 Use double dashes so makedepend doesn't misunderstand the flags we

For 0.9.7 and up, that means util/domd needs to remove those double

dependencies.

cb78486d97 This commits changes to various parts of libcrypto required by the recent 
ENGINE surgery. DH, DSA, RAND, and RSA now use *both* "method" and ENGINE
pointers to manage their hooking with ENGINE. Previously their use of
"method" pointers was replaced by use of ENGINE references. See
crypto/engine/README for details.

Also, remove the ENGINE iterations from evp_test - even when the
cipher/digest code is committed in, this functionality would require a
different set of API calls.

dc2a33d680 "DH_up" had been changed to "DH_up_ref" in libeay.num but the function 
declaration and implementation had not. So a recent update recreated the
original definition in libeay.num ... this corrects it and changes the "dh"
code to the "up_ref" variant.

79aa04ef27 Make the necessary changes to work with the recent "ex_data" overhaul. 
See the commit log message for that for more information.

NB: X509_STORE_CTX's use of "ex_data" support was actually misimplemented
(initialisation by "memset" won't/can't/doesn't work). This fixes that but
requires that X509_STORE_CTX_init() be able to handle errors - so its
prototype has been changed to return 'int' rather than 'void'. All uses of
that function throughout the source code have been tracked down and
adjusted.

5cbc2e8bc1 Give DH, DSA, and RSA functions to "up" their reference counts. Otherwise, 
dependant code has to directly increment the "references" value of each
such structure using the corresponding lock. Apart from code duplication,
this provided no "REF_CHECK/REF_PRINT" checking and violated
encapsulation.

b7727ee616 The indexes returned by ***_get_ex_new_index() functions are used when 
setting stack (actually, array) values in ex_data. So only increment the
global counters if the underlying CRYPTO_get_ex_new_index() call succeeds.
This change doesn't make "ex_data" right (see the comment at the head of
ex_data.c to know why), but at least makes the source code marginally less
frustrating.

4e20b1a656 Instead of telling both 'make' and the user that ranlib 
errors can be tolerated, hide the error from 'make'.
This gives shorter output both if ranlib fails and if
