** Changed in: linux (Ubuntu) Status: Fix Committed => Fix Released -- You received this bug notification because you are a member of नेपाली भाषा समायोजकहरुको समूह, which is subscribed to Xenial. Matching subscriptions: Ubuntu 16.04 Bugs https://bugs.launchpad.net/bugs/1623627 Title: thunder: faulty TSO padding Status in linux package in Ubuntu: Fix Released Status in linux source package in Xenial: Fix Released Bug description: [Impact] Certain packet sizes will trigger spurious TCP retransmissions on Cavium Thunder-X systems when TSO is enabled (the default). This can result in excess traffic and additional latency. [Test Case] Connect 2 systems to a 10G switch: - 1 ThunderX node (the client) - 1 "other" node - doesn't have to be ThunderX (the server) On the server, run the "receiver" command from the attached tcptest tarball: $ ./receiver Also on the server, run tcpdump to capture the traffic: $ sudo tcpdump -i -w tcpdump.out On the client, run the "sender" command from the tcptest tarball, with a 1461 packet size: $ ./sender 1461 1461 Kill the tcpdump process, and open it in wireshark. On failure, you'll see several "[TCP Spurious Retransmission]" packets - on success you should see none. [Regression Risk] Fix is upstream, so regressions will have upstream support. Fix is limited to a driver that is only applicable to the Cavium Thunder-X SoC, so risk is negligible to other platforms.
