Audit tests count the total number of messages sent and compares with total number of CMSG received on error queue. Example: udp gso zerocopy timestamp audit udp rx: 1599 MB/s 1166414 calls/s udp tx: 1615 MB/s 27395 calls/s 27395 msg/s udp rx: 1634 MB/s 1192261 calls/s udp tx: 1633 MB/s 27699 calls/s 27699 msg/s udp rx: 1633 MB/s 1191358 calls/s udp tx: 1631 MB/s 27678 calls/s 27678 msg/s Summary over 4.000 seconds... sum udp tx: 1665 MB/s 82772 calls (27590/s) 82772 msgs (27590/s) Tx Timestamps: 82772 received 0 errors Zerocopy acks: 82772 received Errors are thrown if CMSG count does not equal send count, example: Summary over 4.000 seconds... sum tcp tx: 7451 MB/s 493706 calls (123426/s) 493706 msgs (123426/s) ./udpgso_bench_tx: Unexpected number of Zerocopy completions: 493706 expected 493704 received Also reduce individual test time from 4 to 3 seconds so that overall test time does not increase significantly. v3: Enhancements as per Willem de Bruijn <willemb@google.com> - document -P option for TCP audit Signed-off-by: Fred Klassen <fklassen@appneta.com> --- tools/testing/selftests/net/udpgso_bench.sh | 19 ++++++++++++++++++- 1 file changed, 18 insertions(+), 1 deletion(-)
