sockperf playback tcp mode on RaspberryPi: Error, illegal time or size at line #4

Hello everyone,

I have found another bug with sockperf on RaspberryPi when running a playback test in tcp mode.

Issue description

sockperf can't run playback from a playback file. Testing platform is raspberrypi with raspbian 10 OS.
Same playback file was tested successfully on WSL.

Steps to reproduce the issue

  1. On Raspberrypi, Run sockperf as server
    $sockperf server -p 12000 --tcp

  2. Generate a playback file
    This was done on WSL, because generating this file on RaspberryPi didn't work (but this is another issue ;) )
    $sudo ./gen1.awk > test.pfil

  3. Run sockperf as client in playback mode
    $sockperf playback --data-file test.pfile -p 12000 --tcp --dontwarmup --reply-every 1

this should reprdduce the following error:
$illegal time or size at line #4

What's the expected result?

  • Latency results including avarage latency, total observation and histogram

What's the actual result?

$illegal time or size at line #4

Additional details / screenshot

Hello @akk988,

I do not have RaspberryPi but described issue is not seen on my setup with v3.7.
