sctp panic

sctp panic

[sctp]

Hi

when doing the actions below I get a panic.

- echo 1 > /proc/sys/net/sctp/addip_enable 
- In a C-Programm  
    - socket(AF_INET,SOCK_STREAM,IPPROTO_SCTP);  
    - connect(....)     (with correct filled parameters)

Its no process (waiting in accept) neccessary

Can you show us the panic message and your C prorgam?
This would help reproducing the panic...

The C-Code is:

#include <sys/socket.h>
#include <netinet/in.h>
#include <netdb.h>
#include <stdio.h>
#include <errno.h>
#include <unistd.h>
#include "sctp.h"


int
main(int ac,char **av)
{

  int s;
  char *remhost;
  int port;
  struct hostent *hp;
  struct sockaddr_in server;

  if (ac != 3) {
      printf("usage: %s ip-addr port\n",av[0]);
      exit(1);
  }

  remhost = av[1];
  port = atoi(av[2]);


  server.sin_port = htons(port);
  server.sin_family = AF_INET;
  hp = gethostbyname(remhost);
  if (hp == 0)  {
     fprintf(stderr,"unknown host %s\n",remhost);
     exit(1);
  }
  memcpy((char *)&server.sin_addr,(char *)hp->h_addr,hp->h_length);

  if ((s = socket(AF_INET,SOCK_STREAM,IPPROTO_SCTP)) < 0)  {              
      fprintf(stderr,"socket IPPROTO_SCTP proc %d  failed errno %d\n",getpid(),errno); 
      close(s);                                                
      exit(1);                                           
  }

  if (connect(s,(struct sockaddr *)&server,sizeof server) < 0)        {
         fprintf(stderr,"connect failed errno %d\n",errno);  
         close(s);                                                       
         exit(1);                                                     
  }
}

The crash says:

One more Info:
When calling my programm with 127.0.0.1 as remote ip-addr I get a:
connect failed errno 111  

When calling it with a "non local" address (and also no "accept process" running) I get the Panic.
