[syslog-ng] TOS value updating from afinet_setup_socket

[Dilip Basavaraju]

Dear All,

                I am facing issue in updating TOS value using setsockopt in the function afinet_setup_socket.

                //syslog_ng_dscp_val = 40;


                setsockopt(fd, SOL_IP, IP_TOS, &syslog_ng_dscp_val, sizeof(syslog_ng_dscp_val));
below is the function definition.

I am not getting any print messages. I think this function is not being called. Please suggest me how to update the TOS value.

I am waiting for your responses please.

static gboolean
afinet_setup_socket(gint fd, GSockAddr *addr, InetSocketOptions *sock_options, AFSocketDirection dir)
{
  gint off = 0;

  if (!afsocket_setup_socket(fd, &sock_options->super, dir))
    return FALSE;

  switch (addr->sa.sa_family)
    {
    case AF_INET:
     {
        struct ip_mreq mreq;
            if (dir & AFSOCKET_DIR_RECV)
              {
                memset(&mreq, 0, sizeof(mreq));
                setsockopt(fd, SOL_IP, IP_ADD_MEMBERSHIP, &mreq, sizeof(mreq));
            if (dir & AFSOCKET_DIR_SEND)
                        setsockopt(fd, SOL_IP, IP_MULTICAST_TTL, &sock_options->ttl, sizeof(sock_options->ttl));
              }
        else
        {
                if (sock_options->ttl && (dir & AFSOCKET_DIR_SEND))
                        setsockopt(fd, SOL_IP, IP_TTL, &sock_options->ttl, sizeof(sock_options->ttl));
        }
#if CONFIG_CP_DSCP
        //setsockopt(fd, SOL_IP, IP_TOS, &syslog_ng_dscp_val, sizeof(syslog_ng_dscp_val));
        int tmpSouravVal = 40;          //dilipu
        setsockopt(fd, SOL_IP, IP_TOS, &tmpSouravVal, sizeof(syslog_ng_dscp_val));
#if (CONFIG_CP_IPV6 && CONFIG_CP_DSCP)
        setsockopt(fd, IPPROTO_IPV6, IPV6_TCLASS, &syslog_ng_dscp_val, sizeof(syslog_ng_dscp_val));
#endif
#else

        if (sock_options->tos && (dir & AFSOCKET_DIR_SEND))
                setsockopt(fd, SOL_IP, IP_TOS, &sock_options->tos, sizeof(sock_options->tos));
#endif
        break;
      }
    }
  return TRUE;
}




Thanks and regards
