* Malloc_Allocator isn't a pool, so it needs to fail directly if malloclloyd2010-09-261-1/+3
| | | | | fails, not just return 0 since callers expect that the allocator will either succeed or throw.
* There is a pretty common pattern in the code for testing for internallloyd2010-09-263-0/+86
| | | | | | | | | | errors of the form if(some_expr_indicating_failure) throw Internal_Error("Some mildly informative message"); Make this simpiler with the addition of a BOTAN_ASSERT macro which will throw an exception upon failure.
* At some point I 'simplified' the divide code to always run thelloyd2010-09-261-1/+5
| | | | | | | | | | division algorithm unless x == y, but this could result in n - t + 1 being negative which would cause an attempt to allocate about 4 gigabytes of memory. Fix this, and also add an assertion check in the code to ensure that can't happen in any other way. Never reproduced this with 32 bit digits but it would show up if the build used 8 or 16 bit words.

* Modify bigint_monty_redc to take an additional workspace argument.lloyd2010-09-245-71/+83
| | | | | | | Modify it to avoid a timing condition during the compare at the end; this is done by always doing the subtraction, and then copying to the output either the pre-subtraction or post-subtraction value depending on if the final borrow was set or not.

| | | | | | | | | | | | compatability with 1.8, but actually the signature is completely different anyway because that version took a Timer object, which doesn't exist at all anymore. I suppose I could add an empty Timer class plus subclasses, let someone instantiate it and pass it in, ignoring it, but I'm not feeling this is worth the effort. It would make more sense to add a version with this signature to 1.8, which creates a Default_Benchmark_Timer and uses it.
