* Fairly huge update that replaces the old secmem types with std::vectorlloyd2012-05-181-6/+6
| | | | | | using a custom allocator. Currently our allocator just does new/delete with a memset before deletion, and the mmap and mlock allocators have been removed.
* Remove all uses of MemoryRegion::copy outside of internal uses inlloyd2012-05-181-1/+1
| | | | secmem.h. Mostly replaced by assign or copy_mem.
* First step towards replacing the existing containers with std::vectorlloyd2012-05-181-2/+2
| | | | | | with a custom allocator; remove the 3 argument version of MemoryRegion::copy, replacing with freestanding buffer_insert function.

All of them would fail the lookup, then each of them would add it, but the values returned would be deleted by other threads. Instead, declare that first write wins. Then, the cache stays consistent even if there is a race, the only issue is an extra search and delete. Modify GOST and Skein, as their name() function did not roundtrip properly which caused failures otherwise.

This is a old vestigal thing from a class (SecureBuffer) that used this compile-time constant in order to store the values in an array. However this was changed way back in 2002 to use the same allocator hooks as the rest of the containers, so the only advantage to using the length field was that the initial length was set and didn't have to be set in the constructor which was midly convenient. However this directly conflicts with the desire to be able to (eventually) use std::vector with a custom allocator, since of course vector doesn't support this. Fortunately almost all of the uses are in classes which have only a single constructor, so there is little to no duplication by instead initializing the size in the constructor.

This is very different from STL's clear(), which is basically the equivalent to what is called destroy() in MemoryRegion. So to be able to replace MemoryRegion with a std::vector, we have to rename destroy() to clear() and we have to expose the current functionality of clear() in some other way, since vector doesn't support this operation. Do so by adding a global function named zeroise() which takes a MemoryRegion which is zeroed. Remove clear() to ensure all callers are updated.

Change all callers to be SecureVector instead of SecureBuffer.

| |/ |/| | | | | | | | | | | | | | | | | | | | | | | | | bswap.h); too many external apps rely on loadstor.h existing. Define 64-bit generic bswap in terms of 32-bit bswap, since it's not much slower if 32-bit is also generic, and much faster if it's not. This may be quite helpful on 32-bit x86 in particular. Change formulation of generic 32-bit bswap. It may be faster or slower depending on the CPU, especially the latency and throuput of rotate instructions, but should be faster on an ideally superscalar processor with rotate instructions (ie, what I expect future CPUs to look more like).

Remove BOTAN_DLL exporting macros from all internal-only headers; the classes/functions there don't need to be exported, and avoiding the PIC/GOT indirection can be a big win. Add missing BOTAN_DLLs where necessary, mostly gfpmath and cvc For GCC, use -fvisibility=hidden and set BOTAN_DLL to the visibility __attribute__ to export those classes/functions.
