1. v0.6.1 Aug 31, 2026 · issue 060

   Wireblast v0.6.1 adds the mlx5 Direct Verbs backend with --rx-mode support and AF_XDPAF_XDPA Linux kernel interface that hands raw packets to a userspace program straight off the network card, skipping the kernel's networking stack. It is how userspace tools reach line rate on 100G links. VLAN-filter safety checks.

   • Adds the mlx5 Direct Verbs backend, enabling --rx-mode on Mellanox mlx5 NICsNICsA network interface card or adapter, the hardware that connects a computer to a network. It sends and receives packets over the link. directly through the new backend.
   • Warns when an AF_XDP receive binds fewer queues than the card has, alerting users to potential missed traffic.
   • Refuses an AF_XDP receive when the kernel's VLAN filter would silently drop the traffic, preventing silent data loss.

   • Supports --mode receive with --rx-mode (e.g. udp-port) and --rx-port flags for AF_XDP-based packet reception and counting.
   • New AF_XDP traffic generator for Linux using a single static Go binary — no cgo, no libpcap, no DPDK, no kernel modules.
   • Supports multiple traffic patterns: UDP, TCPTCPA network protocol that delivers a reliable, ordered stream of bytes between two endpoints. It detects lost data and retransmits it. SYN, IMIX (7:4:1 internet mix), raw Ethernet, and PCAPPCAPA packet capture, recorded network packets that can be inspected later.

Cyber tools use it to capture or inject traffic on specific VLANs.) frame generation, CIDRCIDRA notation for a block of IP addresses, such as 10.0.0.0/24. The number after the slash says how many leading address bits identify the network. destination cycling, multi-flow generation (up to thousands of distinct flows), and ECMP/LAG/RSS flow hashing.
