## Target Details

### Ubuntu 20.04 (5.4) [`ubuntu-20.04-5.4`]

- Status: `fail`
- Profile Env: `ubuntu 20.04 kfamily=5.4 arch=x86_64`
- Host Env: `ubuntu 20.04 kfamily=5.4 kernel=5.4.0-216-generic arch=x86_64`
- Failed Stage: `load`
- Load: `fail` (code=-22)
- Attach: `skipped` (mode=best-effort attempted=0 passed=0 failed=0)
- Functional: `skipped`
- Classification: `UNSUPPORTED_MAP_TYPE` (`high`)
- Reason: Map "events" failed to create on this kernel (Invalid argument(-22)); likely an unsupported map type.
- Validator Result: `/home/runner/work/bpfcompat/bpfcompat/.bpfcompat/runs/20260811T070108Z-3c4031/targets/ubuntu-20.04-5.4/validator-result.json`
- Serial Log: `/home/runner/work/bpfcompat/bpfcompat/.bpfcompat/runs/20260811T070108Z-3c4031/targets/ubuntu-20.04-5.4/serial.log`
- Notes:
  - base image sha256: 18f2977d77dfea1b74aee14533bd21c34f789139e949c57023b7364894b7e5e9
  - seed delivery: NoCloud over SMBIOS network URL
  - SSH user selected: ubuntu
  - Validator executed inside VM and result was copied back.
  - bpftool unavailable; used custom capability probes
  - program load failure: name=handle_exec section=tracepoint/syscalls/sys_enter_execve errno=-22
  - program load verifier tail (handle_exec): libbpf: map 'events': failed to create: Invalid argument(-22) libbpf: failed to load object '/tmp/bpfcompat/input/ringbuf_modern.bpf.o'
  - validator load error: code=-22 message=Invalid argument
  - attach status: skipped (mode=best-effort attempted=0 passed=0 failed=0)
  - classification: UNSUPPORTED_MAP_TYPE (high)
  - remediation: Confirm the map type used by this map is supported on this kernel/profile, or ship a fallback artifact. If the artifact's own loader sizes this map at runtime (max_entries=0 in the object), declare it under `maps:` in the manifest instead.
