# Makefile — Compila o programa eBPF sockmap
|
|
#
|
|
# Comandos:
|
|
# make → Compila tudo
|
|
# make vmlinux → Gera vmlinux.h do kernel atual
|
|
# make bpf → Compila o programa BPF
|
|
# make clean → Limpa arquivos compilados
|
|
# make docker-up → Sobe os containers Docker
|
|
# make docker-down→ Para os containers
|
|
# make load → Carrega o eBPF sockmap
|
|
# make unload → Remove o eBPF sockmap
|
|
# make status → Mostra status do sockmap
|
|
# make benchmark → Roda benchmark de latência
