How can the driver safely timestamp any fragment at an offset? about aeron HOT 5 CLOSED

This should be fixed now. There is a test to cover this as well.

I think https://github.com/real-logic/aeron/blob/master/aeron-driver/src/main/c/media/aeron_send_channel_endpoint.c#L301-L308 needs fixed as well, either it shouldn't loop, or it should but only until it successfully sets the timestamp?

This isn't broken as it stands. You can have multiple entries in those vectors consisting of non-fragmented packets. It could be made a little more efficient if you wanted to assume that two packets in the same vector would have the same timestamps. Given that the iov in this case is generally fairly small (default is two), then optimising for an early exit from the loop is probably not worth the complexity.

It’s currently accessing index 0 on each loop iteration, it’s not using i at all

I'd missed that part, it is fixed now
