fix cca buffer overflow in connection report code
-
Ok, I think I found the buffer overflow. It's in the CCA parts. Hopefully fixed now.
-
fix to other cca buffer overflows
-
hopefully fix buffer overflow in connect message (in CCA append), add negative test for snprintf
-
Thanks for this. Can you try master now? 1. Code commit to protect against connect report buffer overflows (in master) 2. Code commit for ifndef I can't speak to low performance. My systems drive 10G links fine. Let me know what you figure out or if I can help diagnose somehow.

Can you file a ticket for this? Iperf should pr int the error code but it currently doesn't.

Hi Andreas, Are you asking the server side output to be on the client side too? Currently the server side output is only on the server side and the client side output is on client side.

Hi All, FYI, here is a good review of Little's Law applied to packets. A major challenge our industry faces is making responsiveness KPIs more prevalent and actionable to network engineers. Currently, many think of capacity only metrics to qualify a link. I'm considering adding the time to service a byte to iperf 2 since TCP is a byte oriented protocol. This time will be calculated on the sender side using Little's law. The "depth" is taken from the tcp_info bytes in flight calculation and the arrival...
