>Description:
I have IPSEC in my kernel and am unable to open sockets IPPROTO_ESP or 
IPPROTO_AH.

This does not seem to happen if the kernel does not have ipsec so I think it's 
a bug.
>How-To-Repeat:


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

int main(int argc, char *argv[])
{
 int sock;
 sock = socket(PF_INET, SOCK_RAW, IPPROTO_ESP);
 if ( sock < 0 )
 {
   perror("sock problem");
 }

}


sock problem: Protocol not supported
>Fix:
