* Prevent a crash in GMP_Engine if the library is shutdown and thenlloyd2010-01-221-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | reinitialized. It would cache an Allocator pointer on first use, and then never zero it, so after the reinit the pointer would be going to a now deallocated Allocator object. Encountered in the SoftHSM test suite, reported by Ondrej Sury. Use a simple reference counting scheme to zero the pointer, and reset the GNU MP memory functions. This also fixes a quite obscure and never reported bug, that if the GMP engine was used, and if the library was deinitialized but then the program tried to use GNU MP, the allocator functions would crash. Now after deinit the allocator funcs revert to the defaults. The reference count is not updated atomically so this is not thread safe, but seems a non-issue; the only time this could happen (especially now that the GMP engine header is internal-only) is if multiple threads were attempting to initialize / shutdown the library at once - which won't work anyway for a variety of reasons, including contention on the (unlocked) global_lib_state pointer. If at some point thread safety is useful here, the refcnt can be locked by a mutex, or kept in an atomic<unsigned int>.

* Un-internal loadstor.h (and its header deps, rotate.h andlloyd2009-12-211-11/+4
| | | | | | | | | | | | | | 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).
* Make many more headers internal-only.lloyd2009-12-166-37/+68
| | | | | | | | | | | | | Fixes for the amalgamation generator for internal headers. 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.

* Consolidate the non-canonical epoch timers, like cpuid and Win32'slloyd2009-12-015-9/+5
| | | | | | | | | | | | | | QueryPerformanceCounter, into an entropy source hres_timer. Its results, if any, do not count as contributing entropy to the poll. Convert the other (monotonic/fixed epoch) timers to a single function get_nanoseconds_clock(), living in time.h, which statically chooses the 'best' timer type (clock_gettime, gettimeofday, std::clock, in that order depending on what is available). Add feature test macros for clock_gettime and gettimeofday. Remove the Timer class and timer.h. Remove the Timer& argument to the algorithm benchmark function.
