"Vijay Pandurangan from Twitter warns about a Linux kernel bug that
causes containers using Virtual Ethernet devices for network routing
to not check TCP checksums. Examples of software stacks that use
Virtual Ethernet devices are Docker on IPv6, Kubernetes, Google
Container Engine and Mesos. The kernel flaw results in applications
incorrectly receiving corrupt data in a number of situations, such as
with bad networking hardware. The bug dates back at least 3 years or
more – it is present in kernels as far back as the Twitter engineering
team has tested. Their patch has been reviewed and accepted into the
kernel, and is currently being backported to -stable releases back to
3.14 in various distributions. If you use containers in your setup,
Pandurangan recommends that you deploy a kernel with this patch."
