We are excited to announce the release of PF_RING 9.2. This release brings numerous improvements across the core library, kernel module, and drivers, with a strong focus on stability, performance, and compatibility with modern Linux kernels and hardware platforms.
PF_RING Kernel Module and Library
The user-space library has been refined to improve stability and compatibility, with improvements in IPv6 and GRE packet decoding, and compatibility with the latest nDPI library for Layer-7 detection.
The kernel module introduces several important enhancements, including improved namespace and container support, enabling smoother operation in virtualized and containerized environments.
A new cluster type (cluster_per_flow_ip_with_dup_tuple_ext) has also been introduced for kernel-based clustering with standard (non zero-copy) drivers.
The Zero-Copy API has been enhanced and extended with GTP-over-GRE support for zbalance GTP hashing, improving flexibility for telecom workloads and tunneling scenarios.
The FT (Flow Table) library has been updated to align with the latest nDPI API. CAPWAB decoding has been fixed, ensuring correct identification and handling of these protocols
