ICMPv6 echo reply handler by gspivey · Pull Request #56 · gspivey/dpdk-stdlib-rust

gspivey · 2026-05-20T04:31:22Z

Roadmap item addressed

IPv6 task 7: ICMPv6 echo reply — auto-respond to ping6, parallel to our existing IPv4 ICMP echo reply.

Changes

New module dpdk-udp/src/icmpv6.rs providing:

Icmpv6Packet — parsed ICMPv6 echo request/reply struct
parse_icmpv6_packet() — parse ICMPv6 echo from raw Ethernet frames (handles extension headers)
build_icmpv6_frame() / build_echo6_request() — frame construction with IPv6 pseudo-header checksum
icmpv6_checksum() — RFC 4443 §2.3 checksum using IPv6 pseudo-header
Icmpv6Handler — stateful handler that auto-responds to echo requests for registered local IPs

Integration into UdpSocket:

Added icmpv6_handler field, initialized on bind
RX path handles ICMPv6 echo requests when auto_icmp is enabled and ethertype is IPv6

Tests added (24)

Build/parse roundtrip (echo request, echo reply, empty payload)
Checksum computation, verification, and corruption detection
make_echo_reply() address/field swapping
Handler: responds to local IPs, ignores others, supports multiple IPs
Edge cases: rejects IPv4, truncated frames, UDP-over-IPv6, too-short frames
Wire format: ethertype, next header, payload length
Link-local and loopback address handling
Synthetic performance benchmark (10K build+parse cycles)

Tradeoffs

Only handles echo request/reply (types 128/129). ICMPv6 error handling (type 1-4) is a separate roadmap item (Add pre-built DPDK AMI support to reduce deployment time #8).
Handler is initialized with Ipv6Addr::UNSPECIFIED since the socket is currently IPv4-only. Once SocketAddrV6 support lands (task 3), the handler will be initialized with the actual bound IPv6 address.
Reuses the existing auto_icmp flag to control ICMPv6 responses (same toggle for v4 and v6).

Implements roadmap item 7: ICMPv6 echo reply (auto-respond to ping6). New module dpdk-udp/src/icmpv6.rs provides: - ICMPv6 packet parsing (echo request/reply) - ICMPv6 frame building with IPv6 pseudo-header checksum - Icmpv6Handler that auto-responds to echo requests - Integration into UdpSocket RX path (parallel to IPv4 ICMP) 24 unit tests covering: - Build/parse roundtrip for echo request and reply - Checksum computation and corruption detection - Handler address matching (responds only to local IPs) - Edge cases (truncated frames, wrong protocol, IPv4 rejection) - Wire format verification - Synthetic performance benchmark (build+parse cycle)

Synthetic UDP Performance Results

Measures framework overhead: sync dpdk_udp::UdpSocket vs async (std::sync::Mutex + try_recv_from).

Test	Payload	Sync PPS	Async PPS	Ratio (sync/async)	Async ns/op
TX send_to	64B	11.2M	10.2M	1.1x	98
RX recv_from	64B	3.4M	3.8M	0.9x	262
TX send_to	1400B	1.7M	1.7M	1.0x	605
RX recv_from	1400B	990.1K	1.0M	1.0x	974

Avg sync/async ratio: 1.0x, worst: 1.1x

Good: Async wrapper is within 1.1x of sync — minimal framework overhead.
