1addf08ccd don't have Conn.Read return an error for temorary crypto failures from e.g. out of order packets, just drop the packet and keep blocking until there's usable traffic 2019-05-31 17:51:01 -05:00

5d323861f0 properly fix the memory errors, it was caused by a function returning and PutBytes-ing a buffer before a worker had a chance to decrypt the buffer, so it would GetBytes the same buffer by dumb luck and then get an illegal overlap 2019-04-26 22:21:31 -05:00

01ea6d3d80 somehow this doesn't seem to deadlock or crash from buffer reuse (util.PutBytes), but I have no idea why it was doing that before and not now 2019-04-26 21:49:11 -05:00
