macos ip rule

[cuicanju]

Could you please advise on how to set up routing rules on macOS?

static int
hev_socks5_session_tcp_bind (HevSocks5 *self, int fd,
                             const struct sockaddr *dest)
{
    HevConfigServer *srv;
    unsigned int mark;

    LOG_D ("%p socks5 session tcp bind", self);

    srv = hev_config_get_socks5_server ();
    mark = srv->mark;

    if (mark) {
        int res = 0;

#if defined(__linux__)
        res = setsockopt (fd, SOL_SOCKET, SO_MARK, &mark, sizeof (mark));
#elif defined(__FreeBSD__)
        res = setsockopt (fd, SOL_SOCKET, SO_USER_COOKIE, &mark, sizeof (mark));
#endif
        if (res < 0)
            return -1;
    }

    return 0;
}

And why is there no need to set a mark in the macOS environment here?

• From freebsd manpage, that's for ipfw/dummynet. macOS uses pf which does not uses any kind of mark.

  SO_USER_COOKIE can be used to set the uint32_t so_user_cookie field  in
     the  socket.   The  value is an uint32_t, and can be used in the kernel
     code that manipulates traffic related to the socket.  The default value
     for the field is 0.  As an example, the value can be used as the skipto
     target or pipe number in ipfw/dummynet

Thank you very much for your response and the discussions that helped solve the problem that has troubled me for a long time
