fix for: iperf2 long time run on 40Gb/s NIC crashes, found ubuntu Bug #1771283, reported by Ike Panhc, increase format support to Peta as well
[Regression Potential]
This patch was tested on ARM64 Cavium ThunderX2 systems and no regressions were found.
iperf calculates the sum of all bytes transferred and prints this sum like 'Sum: 100Mbytes'. For example if total data transferred was (simplified) 100,000,000 Bytes, iperf would print Sum: 100 Mbytes. The suffix Mbytes is stored in a static array and it uses the number of time it had to divide the sum by 1000 to determine the index to that array. iperf only accounted for Sums up to GBytes, causing it to segfault on Sums of +TBytes. Currently the patch extends this array to Peta Bytes, but you will segfault again if the sum is in the order of Exabyte or larger. This might be achievable by using 100G connections between server-client (Mellanox 100G nic & switch) and running iperf at max throughput for a long long long periods of time. |
