xdp-check

XDP compatibility checker and runtime verification

overview

xdp-check verifies that your Linux system supports XDP and checks if XDP programs (specifically agave_xdp) are currently loaded and active.

features

• kernel compatibility check - verifies kernel version and XDP support
• capabilities check - validates required system capabilities
• system resources - checks rlimit and memlock settings
• network interface check - verifies NIC driver support for XDP
• runtime detection - detects loaded XDP programs using BPF syscalls (via aya)

requirements

• linux kernel 4.18+ (6.xx recommended for full XDP support)
• root/sudo privileges (for runtime checks and BPF operations)

building

cargo build --release

the binary will be available at ./target/release/xdp-check

usage

full sys

sudo ./xdp-check

check runtime status

verify if agave_xdp or other XDP programs are currently loaded:

sudo ./xdp-check runtime

check specific interface

sudo ./xdp-check nic eth0

debug logging

enable detailed debug logs:

sudo RUST_LOG=debug ./xdp-check runtime

runtime detection

runtime check uses the aya library to query loaded BPF programs directly via syscalls. it will detect:

• whether agave_xdp program is loaded
• program ID and tag/hash
• program type (XDP)
• other XDP programs in the system
