| | | | | | | | | | | | | | | | | | | | | | 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 vectorslloyd2012-05-2558-193/+205
| | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | was not the right size for a signature (following DSA). This would silently convert to an empty vector which we would treat as a valid message on the return. However the EMSA checks will always fail so not a huge problem. While checking this out I noticed that an empty value for EMSA4 would result in us reading memory we didn't own.

| | | | | | | | | | | | | | | | | | exceptions thrown in end_msg (for instance in CBC decryption when the padding is bad) more or less screwed up the pipe completely. Allowing reset here at least allows an escape hatch.

However it is also used on AMD Bulldozer processors to signal half-precision floating point support so we could false positive there.

| | | | | | | | | | | | | | | | | | | | | didn't work on older GCC/binutils. Instead hardcode the expression for rdrand %eax, which should work everywhere. Also, avoid including immintrin.h unless we're going to use it, to avoid problems with older compilers that lack that header (this caused build failures under GCC 3.4.6).

The peer_certs variable was not set until after the Session object was created, meaning the session (or session ticket) would not include client certs. Worse, they would be included in the next session saved, so if a client presented one cert, then renegotiated and presented another one, the first cert would be associated with the second session!

TLS::Channel::heartbeat can initiate a new heartbeat if the peer allows it. Heartbeat replies are passed back to the application processing function with an Alert value of HEARTBEAT_PAYLOAD (a 'fake' value, 256, which is out of range of the valid TLS alert space), along with the sent payload. The RFC requires us to have no more than one heartbeat 'in flight' at a time, ie without getting a response (or a timeout in the case of DTLS). Currently we do not prevent an application from requesting more.

Need to figure out how to transfer the v, b, B params from the server key exchange message to the client key exchange. The DH variants do this by passing a Private_Key via server_kex_key call, but wrapping SRP params in a Private_Key really doesn't feel right. Not sure what to do here. Possibly both SRP and DH should return a Key_Exchange_Material* that a client key exchange knows how to dynamic cast on.
