This is to announce a new PF_RING major release 7.8.

The main changes in this release include:

  • The new ice ZC driver supporting E800 Series 100 Gigabit Intel adapters.
  • Hardware timestamp support  for packet trailers and keyframes generated by Arista 7150 Series and Metawatch. This also includes device information such as the Device ID and the Port ID.
  • BPF support for all ZC devices and queues, both to filter received or transmitted traffic.
  • ZC API extensions to further simplify its use, which is one of the main advantages of this library, together with performance and flexibility.
  • FT (Flow Table) improvements for flow export with slicing, which is the ability to deliver periodic flow updates before flow termination. Improved also the application protocol detection.
  • New libpcap v.1.9.1 and tcpdump v.4.9.3 including fixes for several CVEs.
  • Extended nBPF primitives to match Local or Remote IPs.
  • More sample applications and extensions to the existing ones to cover more use cases.

Below you can find the complete changelog.

Enjoy!
