There is a function in include/net/netfilter/nf_socket.h to decide if a socket has IP(V6)_TRANSPARENT socket option set or not. However this does the same as inet_sk_transparent() in include/net/tcp.h include/net/tcp.h:1733 /* This helper checks if socket has IP_TRANSPARENT set */ static inline bool inet_sk_transparent(const struct sock *sk) { switch (sk->sk_state) { case TCP_TIME_WAIT: return inet_twsk(sk)->tw_transparent; case TCP_NEW_SYN_RECV: return inet_rsk(inet_reqsk(sk))->no_srccheck; } return inet_sk(sk)->transparent; } tproxy_sk_is_transparent has also been refactored to use this function instead of reimplementing it.
