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.
