I built Yakkety, Xenial and Vivid test kernels with the request commit. The can be downloaded from:
Yakkety: http://kernel.ubuntu.com/~jsalisbury/lp1636656/yakkety Xenial: http://kernel.ubuntu.com/~jsalisbury/lp1636656/xenial Vivid: http://kernel.ubuntu.com/~jsalisbury/lp1636656/vivid Can you test this kernels and see if they resolve this bug? Trusty and Precise require some backporting, but I'll post a link to them when they are built. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1636656 Title: [Hyper-V] netvsc: fix incorrect receive checksum offloading Status in linux package in Ubuntu: In Progress Status in linux source package in Precise: In Progress Status in linux source package in Trusty: In Progress Status in linux source package in Vivid: In Progress Status in linux source package in Xenial: In Progress Status in linux source package in Yakkety: In Progress Bug description: The Hyper-V netvsc driver was looking at the incorrect status bits in the checksum info. It was setting the receive checksum unnecessary flag based on the IP header checksum being correct. The checksum flag is skb is about TCP and UDP checksum status. Because of this bug, any packet received with bad TCP checksum would be passed up the stack and to the application causing data corruption. The problem is reproducible via netcat and netem. This had a side effect of not doing receive checksum offload on IPv6. The driver was also also always doing checksum offload independent of the checksum setting done via ethtool.
