The following two new examples have been added to the SDK repository and the MkDocs:
-
cBPF Virtual Patch (single-thread)
A demonstration of a virtual patch between two nodes with an attached cBPF filter on one of the interfaces.

eBPF Virtual Patch (single-thread)
A demonstration of a virtual patch between two nodes with an attached eBPF programme on one of the interfaces. Communication between kernel and user space is also included in this example via a BPF ring buffer.

They both attach the xBPF filter (programme) on a socket basis. In the (near) future, the complete implementation inside CORD-FLOW is planned to look as follows:
Enjoy!
