3904e809b2 Add two test cases for shortcut logic used when one operand is zero and
the other is also the target.

241f524238 Fix a bogus t_malloc_fail in one of the mpi_add_abs() tests.
Add several subtraction test cases and modify some others to better
exercise the carry logic, which is far more complex for subtraction than
for addition.

Add test cases where the target is the same MPI as one or both operands.

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.

8d0e24dee7 Remove the "trailing garbage" version of the mpi_cmp() test. It would
be better to systematically pad MPIs used in all tests with garbage.

Greatly expand the number of mpi_cmp() tests to cover all possible
combinations of same or different sign, same or different msb and same
or different magnitude.

f18b915b67 Fix the "x = a + b" allocation failure test. Since a and b were
equal, mpi_sub_abs() would return early and the test would never
exercise the mpi_grow() call which is intended to fail.

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
end of the buffer.

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

e21452d0c7 Add a few tests for subtraction. They're not particularly well thought
out, because currently subtraction does not work at all, but they work
well enough in the sense that they fail with the current implementation.

03867777c6 Add numerous tests, mostly for allocation failures and edge conditions.
Add a t_compare_mpi() predicate which checks that two MPIs have the same
value (but not necessarily the exact same representation).
Clean up and improve existing tests.

7b6b493509 Declare t_malloc_fail_after. 2014-12-29 23:49:50 +00:00
Dag-Erling Smørgrav
3ec87c7a8c Introduce t_malloc_fail_after: if non-zero, it serves as a countdown to
setting t_malloc_fail.  Also, enforce t_malloc_fail in realloc(), but not
before checking that the argument was valid.

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.

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().

7a09b0638f I had forgotten that t_add_test() is actually a printf()-like variadic
function, which obviates the need for asprintf() in the string comparison
and equality tests.

82e32027af Move the decision of whether to check for memory leaks from the malloc()
code to the driver and allow an environment variable to override the
default (on unless coverage is enabled).

56eccb99fe Add two utility functions which check if a string contains something that
can be interpreted as either true or false.  Use this instead of a basic
non-NULL test for the CRYB_PERFTEST check.

eb10ce6d05 If the test case changes desc, it *must* point to an allocated buffer

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.

8ef2266a4b r103 was incomplete. It changed the checks in the configure script (and
accidentally introduced a no-op line), but did not change the checks in
the header, so we ended up always using our own [bl]e{32,64}{enc,dec}.

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.
