*NOSUPPORT errnos likely mean there is configuration issue rather than
test failure.

e.g. missing dccp module in netstress.c which was so far set as TBROK:
safe_net.c:117: BROK: netstress.c:654: socket(10, 6, 33) failed: ESOCKTNOSUPPORT

Hi
    I am sorry I forget to report my debug info on RHEL7.5Beta about 
this question.
I write a testcase on RHEL7.5Beta. the test case is below.

#include <netinet/in.h>
#include <sys/socket.h>
#include <stdio.h>

int main (int argc, const char * argv[])
{
     //create a dccp socket
     int server_socket = socket(AF_INET6, SOCK_DCCP, IPPROTO_DCCP);
     if (server_socket == -1) {
         perror("socket error");
         return 1;
     }
    printf("test is ok \n");
}

And the  RHEL7.5Beta will report "Socket type not supported"  when run 
my testcase  on RHEL7.5Beta .
and the RHEL7.4GA will report "Permission denied " when run my testcase 
on RHEL7.4GA
it's ok when run my testcase on RHEL7.3GA.

That's all.

Thanks
Lianwen Sun

This is ESOCKTNOSUPPORT.

Not sure why it does not report ESOCKTNOSUPPORT, but I've seen some of these.

Thanks for testing!
