PF_RING Library

  • Flow offload support
    • New PF_RING_FLOW_OFFLOAD pfring_open() flag to enable hw flow offload on supported cards (received buffers are native metadata)
    • New PF_RING_FLOW_OFFLOAD_NOUPDATES pfring_open() flag to disable flow updates with hw flow offload enabled: only standard raw packets with a flow id are received
    • New PKT_FLAGS_FLOW_OFFLOAD_UPDATE packet flag to indicate flow metadata in the received buffer (generic_flow_update struct)
    • New PKT_FLAGS_FLOW_OFFLOAD_PACKET packet flag to indicate raw packet with flow_id in pkt_hash
    • New PKT_FLAGS_FLOW_OFFLOAD_MARKER packet flag to indicate marked raw packet
  • Fixes for ARM systems

ZC Library

  • New pfring_zc_set_app_name API
  • PF_RING_ZC_PKT_FLAGS_FLOW_OFFLOAD flag to enable hw flow offload
  • Fixed BPF filters in SPSC queues
  • Fixed hugepages cleanup in case of application dropping privileges
  • Fixed sigbus error on hugepages allocation failure on numa systems
  • Fixed multiple clusters allocation in a single process

PF_RING-aware Libpcap/Tcpdump

  • Libpcap update v.1.8.1
  • Tcpdump update v.4.9.2

PF_RING Kernel Module

  • Docker/containers namespaces isolation support
  • Fixed capture on Raspberry Pi
  • Implemented support for VLAN filtering based on interface name (., where ID = 0 accepts only untagged packets)
  • New cluster types cluster_per_flow_ip_5_tuple/cluster_per_inner_flow_ip_5_tuple to balance 5 tuple with IP traffic, src/dst mac otherwise
  • Fixed hash rule last match, new hash_filtering_rule_stats.inactivity stats

PF_RING Capture Modules

  • Accolade flow offload support
    • New hw_filtering_rule type accolade_flow_filter_rule to discard or mark a flow
  • Netcope support
    • New hw_filtering_rule type netcope_flow_filter_rule to discard a flow
  • Improved Fiberblaze support
    • pfring_get_device_clock support
    • Ability to set native filters by setting as BPF string 'fbcard:'
    • Fixed TX memory management
    • Fixed subnet BPF filters
    • Fixed drop counter
    • Fixed capture mode
    • Fixed sockets not enabled
    • FPGA error detection
  • Endace DAG update
  • npcap/timeline module compressed pcap extraction fix

Drivers

  • ixgbe-zc driver update v.5.0.4
  • i40e-zc driver update v.2.2.4

nBPF

  • Fixed nBPF parser memory leak

Examples

  • New pfsend option -L to forge VLAN IDs
  • zbalance_ipc improvements
    • Ability to dump output to log file (-l)
    • Fixed privileges drop (-D)

Misc

  • Fixed systemd dependencies, renamed pfring.service to pf_ring.service
  • New /etc/pf_ring/interfaces.conf configuration file for configuring management and capture interfaces
