PF-RING is a high-performance traffic processing library, offering superior performance compared to AF_PACKET. It is particularly well-suited for high-speed network environments.

The integration of PF_RING with Kubeshark is depicted in the following diagram:

Worker's Architecture

Due to PF_RING’s requirement for specific support based on the Node’s kernel version, and the vast variety of kernel versions, Kubeshark’s support for PF_RING cannot be universally guaranteed.

Adding Support for Your Kernel Version

We consolidate all PF_RING module files into a single image named kubeshark/pf-ring-module:all. To check if your kernel version is supported, visit this link.

Should your kernel version lack support, you can undertake the following steps to incorporate a new PF_RING module into the kubeshark/pf-ring-module:all image:

  1. Download the latest release of pf-ring-compiler for your platform from here.
  2. Execute pfring-compiler for your target platform (for instance, EKS, which uses Amazon Linux 2):
pfring-compiler compile --target al2

{"level":"info","msg":"compile job default/al2-pf-ring-compiler created","time":"2024-03-21T14:17:52+02:00"}

{"level":"info","msg":"copying kernel module to local fs","time":"2024-03-21T14:19:41+02:00"}
{"level":"info","msg":"kernel module copied to pf-ring-5.10.210-201.852.amzn2.x86_64.ko","time":"2024-03-21T14:19:43+02:00"}
{"level":"info","msg":"cleaning up compile job","time":"2024-03-21T14:19:43+02:00"}

You will obtain a module named pf-ring-5.10.210-201.852.amzn2.x86_64.ko in the current folder, formatted as pf-ring-<kernel version>.ko.

  1. Clone the pf-ring-compiler repository:
git clone
cd pf-ring-compiler
git checkout -b "add-module-<version>"
  1. Transfer the kernel module from step 2 into the modules/ko folder.
  2. Commit your modifications and submit a pull request (PR):
git add modules/ko/pf-ring-5.10.210-201.852.amzn2.x86_64.ko
git commit -S -m "Add PF_RING module for kernel 5.10.210-201.852.amzn2.x86_64"
git push origin add-module-<version>

After creating the PR, wait for it to be reviewed and merged. Following the merge, a GitHub Action pipeline will construct a new kubeshark/pf-ring-module:all image, enabling Kubeshark to support PF_RING for your kernel version.
