Tomasz Drwięga	c8f57315a8	[stable] Missing AuRa backports (#7499 ) * Merge pull request #7368 from paritytech/td-future-blocks Wait for future blocks in AuRa * Advance AuRa step as far as we can and prevent invalid blocks. (#7451) * Advance AuRa step as far as we can. * Wait for future blocks. * Problem: AuRa's unsafeties around step duration (#7282) Firstly, `Step.duration_remaining` casts it to u32, unnecesarily limiting it to 2^32. While theoretically this is "good enough" (at 3 seconds steps it provides room for a little over 400 years), it is still a lossy way to calculate the remaining time until the next step. Secondly, step duration might be zero, triggering division by zero in `Step.calibrate` Solution: rework the code around the fact that duration is typically in single digits and never grows, hence, it can be represented by a much narrower range (u16) and this highlights the fact that multiplying u64 by u16 will only result in an overflow in even further future, at which point we should panic informatively (if anybody's still around) Similarly, panic when it is detected that incrementing the step counter wrapped around on the overflow of usize. As for the division by zero, prevent it by making zero an invalid value for step duration. This will make AuRa log the constraint mismatch and panic (after all, what purpose would zero step duration serve? it makes no sense within the definition of the protocol, as finality can only be achieved as per the specification if messages are received within the step duration, which would violate the speed of light and other physical laws in this case). * Fix tests. * detect different node, same-key signing in aura (#7245) * detect different node, same-key signing in aura * reduce scope of warning	2018-01-08 23:09:11 +01:00
