Send the function codes from the error functions to the bit bucket,

as was done earlier in libssl. Thanks inoguchi@ for noticing libssl had more reacharounds into this. ok jsing@ inoguchi@

Construct a BN_gcd_nonct, based on BN_mod_inverse_no_branch, as suggested

2017-01-25T06:15:44+00:00

by Alejandro Cabrera to avoid the possibility of a sidechannel timing attack during RSA private key generation. Modify BN_gcd to become not visible under LIBRESSL_INTERNAL and force the use of the _ct or _nonct versions of the function only within the library. ok jsing@

use BN_div_nonct where it is safe to do so.

Add ct and nonct versions of BN_mod_inverse for internal use

2017-01-21T11:00:47+00:00

ok jsing@

Split out BN_div and BN_mod into ct and nonct versions for Internal use.

BN_CTX_get() can fail - consistently check its return value.

2015-02-09T15:49:22+00:00

There are currently cases where the return from each call is checked, the return from only the last call is checked and cases where it is not checked at all (including code in bn, ec and engine). Checking the last return value is valid as once the function fails it will continue to return NULL. However, in order to be consistent check each call with the same idiom. This makes it easy to verify. Note there are still a handful of cases that do not follow the idiom - these will be handled separately. ok beck@ doug@

Only import cryptlib.h in the four source files that actually need it.

2014-07-11T08:44:49+00:00

Remove the openssl public includes from cryptlib.h and add a small number of includes into the source files that actually need them. While here, also sort/group/tidy the includes. ok beck@ miod@
