7a90ca7b42 Since X may point to the same MPI as either G or L (or even both), we
can't set the carry flag based on the contents of G or L after having
modified X.  Instead, compute and stash the new carry value first.

0d483f20ab Fix msb calculation. We may have to backtrack quite a bit, for
instance when subtracting two nearly equal large numbers.

1c024928f9 Fix off-by-one bug in mpi_cmp() which could cause it to read past the

43b870dc83 WIP: implement subtraction correctly. The actual result is now correct
most of the time, but the MSB calculation is not.

bc8e9d67ba In both mpi_add_abs() and mpi_sub_abs(), make sure that the target is
untouched if the operation fails.  Also ensure that A = A +/- A works.

98c6349d4a In mpi_zero(), save a memset() if the target is already zero. 2014-12-29 23:22:54 +00:00

1412dac680 Shifting any number by zero places is a no-op, but so is shifting zero by
any number of places.

8228f19d5a In mpi_copy(), any failure should leave the target untouched. 2014-12-29 23:18:57 +00:00
Dag-Erling Smørgrav
82f5c5cf77 In mpi_load(), use be32dec() when possible.
In mpi_set(), it is impossible for the value being loaded to exceed
the minimum size of an mpi; thus, there is no need for mpi_grow().

f82bbc1400 Catch up with OpenPAM's latest OATH changes:
Add an oath_mode(3) function which translates from mode names to numbers.

 Consistently use UINT_MAX, not -1, to indicate an invalid response.

 Change the meaning of the window parameter to always indicate the number
 of codes to check *in addition* to the current code.  Note that for TOTP,
 the window goes in both directions; a window of 1 means to check the
 current code plus the previous and next.

6ed802ddf3 Consistently use #if HAVE_FOO instead of #ifdef HAVE_FOO. The reason is
that AC_CHECK_DECLS([foo]), unlike AC_CHECK_FUNCS([foo]), will always
define HAVE_FOO, so #ifdef HAVE_FOO will always be true even if it is 0.
This commit finally fixes the [bl]e{32,64}{enc,dec} issue on Linux.

20dab3e342 Provisionally include strlcmp(), although it is not (currently) used
anywhere.  Opinion is divided as to whether this is useful, or whether
its usefulness is outweighed by its awkwardness.  Still, we have it, so
we may as well commit it.

Remove $Cryb$ tags as it is likely that the code will move to git.
