* Two more locking_allocator bugs. In allocate, we did not setlloyd2012-05-251-5/+9
| | | | | | | | | | | best_fit->first in cases where we had an almost exact match (exact fit but with some alignment bytes at the start), meaning that not only would we lose those bytes forever, but that we might later hand out a range overlapping with what we handed to our current caller. Also, in deallocate, lower_bound on the freelist might return end() (for instance if the freelist is entirely empty). Avoid trying to update the iterator in that case.
* Fix alignment again and add assert checks so we don't mess up again.lloyd2012-05-251-4/+30
| | | | | | We previously ignored a block that was exactly the right size for the allocation and the needed alignment. If we find such a block prefer it over any other (non-exact) blocks to minimize fragmentation.
* For block and stream ciphers, don't set the size of the key vectorslloyd2012-05-251-0/+8
| | | | | | | | | | | until we are actually setting a key. This avoids the problem of prototype objects consuming not just memory but the precious few bytes of mlock'able memory that we're given by Linux. Use clear_mem instead of a loop in BigInt::mask_bits If OS2ECP encounters an invalid format type, include what type it was in the exception message.
* Instead of a map of start->length for recording the free list use alloyd2012-05-242-33/+44
| | | | | | vector of (start,length) where we are careful to maintain the correct ordering. Much much faster than the map version as it mostly avoids allocations and copies.
* Properly align return values of mlock_allocator. Be more careful aboutlloyd2012-05-221-13/+34
| | | | | | | | | | | pointer checks as a sufficiently smart compiler might optimize way pointer comparisons otherwise. Avoid using an iterator value after we have released it from the map. Reduce the default buffer size to 1K to reduce pressure on mlock memory. Drop the old mlock wrapper code.
* Remove a debug call in secmem.h.lloyd2012-05-224-4/+220
| | | | | | | | | Add a new mlock allocator which is far superior to the previous one both in terms of behavior (will lock exactly as much memory as we can actually mlock and will fall back to new/delete in all other cases), and much better and much simpler freelist than the old mem_pool code. Currently we only support systems with mmap+mlock, however it should be easy to extend to also support Windows VirtualLock if desired.
