Hello Colomar, I just found a potential bug in the bpf-helpers page. Under the https://www.man7.org/linux/man-pages/man7/bpf-helpers.7.html: ``` u64 bpf_get_socket_cookie(struct sk_buff *skb) Description If the struct sk_buff pointed by skb has a known socket, retrieve the cookie (generated by the kernel) of this socket. If no cookie has been set yet, generate a new cookie. Once generated, the socket cookie remains stable for the life of the socket. This helper can be useful for monitoring per socket networking traffic statistics as it provides a global socket identifier that can be assumed unique. Return A 8-byte long non-decreasing number on success, or 0 if the socket field is missing inside skb. u64 bpf_get_socket_cookie(struct bpf_sock_addr *ctx) Description Equivalent to bpf_get_socket_cookie() helper that accepts skb, but gets socket from struct bpf_sock_addr context. Return A 8-byte long non-decreasing number. u64 bpf_get_socket_cookie(struct bpf_sock_ops *ctx) Description Equivalent to bpf_get_socket_cookie() helper that accepts skb, but gets socket from struct bpf_sock_ops context. Return A 8-byte long non-decreasing number. ``` The function bpf_get_socket_cookie repeats three times. The second one should be bpf_get_socket_cookie_addr and the third one should be bpf_get_socket_cookie_ops.
