task IP as source IP: ● connect(2): bpf_bind(task_ip) ● sendmsg(2): bpf_bind(task_ip) Handle TCP client A connecting to TCP server B in same task by [::1]: ● listen(2): track server port by tracking to send task TCP traffic to TLS forward proxy transparently for a service? Solution: ● Redirect client on connect(2) by BPF_CGROUP_INET6_CONNECT and BPF_CGROUP_SOCK_OPS programs → ● In proxy on accept(2)

kernel networking, pardon my mistake and welcome corrections! Sad Rabbit Has No Memory • A faulty client spammed “AMQP consumers” • RabbitMQ cluster runs out of memory • Need a way to limit the number
