f4237ce57b GFp_BN_mod_exp_mont_consttime: Have caller pass the exponent bit length. 
This is a step towards doing the bit length calculation in Rust.

44cbfa9ebf Remove BIGNUM::neg: BIGNUMs are now always nonnegative/unsigned. 
Note that in each place where the value of `neg` was changed for some
`BIGNUM`, either it is set to zero (not negative), the same value as
another `BIGNUM`'s `neg` value, or to the XOR of two `BIGNUM`'s `neg`
values. Thus, there was no way the `neg` flag could ever be set to a
nonzero value.

e90ba18b5f Remove GFp_BN_abs_is_word(). 
Inline the necessary logic into the one caller, `GFp_BN_is_one()`.

a5a764fe94 Remove the now-unused GFp_BN_cmp(). 2017-04-24 22:45:22 -10:00
Brian Smith
4c541a070d Remove GFp_BN_cmp_word(). 
`GFp_BN_cmp_word()` uses `GFp_BN_cmp()`, which we are aiming to remove.

Brian Smith
f4ccd334a6 Replace uses of GFp_BN_cmp() with GFp_BN_ucmp() where equivalent. 
Note that all these uses already verify that the inputs aren't negative
beforehand, so there was no advantage to them using `GFp_BN_cmp()` over
`GFp_BN_ucmp()`.

aa325730f1 Remove GFp_BN_sub(). 
Inline the necessary logic into `GFp_BN_sub`'s lone caller and
remove `GFp_BN_sub`.

0dc12ef70f Replace confusing use of GFp_BN_mod_sub_quick(). 
`GFp_BN_mod_sub_quick()` is documented to require its non-modulus
operands to be less than the modulus, but in this case we were passing
the modulus itself as one of them. Avoid doing that, and add assertions
regarding the range of the inputs to `GFp_BN_mod_sub_quick()`.

Also, this makes it clearer that the function isn't constant-time yet.

a6b339b78c Remove GFp_BN_add. 
Replace the use of GFp_BN_add with direct usage of the specific case
needed.

efdffc91db Remove now-unused BIGNUM functions, and bn_test.cc (the last C++ use). 
These functions can be removed thanks to the new modular inversion
implementation.

39b35d3fda Move Curve25519 operations into their own module. 
This supports both the short-term oxidization of Curve25519 operations
and the longer-term unification with the NIST EC code, whose module
structure we now mirror more closely.

ff71d521ff Use "GFp/" instead of "openssl/" for #includes. 
Avoid any potential conflicts with OpenSSL header files by using a
different namespace.

3896e21bba Use libc's __errno_location() and EINTR instead of defining our own. 
We need to link to libc anyway since we call its syscall(2), so just do
it through the libc crate. When we remove the syscall(2) dependency
then we'll also remove this libc crate dependency.

Brian Smith
2ff814b6b8 Only use _xgetbv() with MSVC, not all Windows-targeting compilers. 
At least some Windows-targeting compilers don't have `_xgetbv()`. MSVC
x86-64 doesn't have inline asm, and its 32-bit inline asm does not use
GCC syntax, so we need to retain the MSVC-specific code path.
