>Description:
Calling shutdown(2) on a non-connected socket should fail with ENOTCONN
according to the manpage. Instead, it succeeds.
>How-To-Repeat:
Run this program. It should hit the perror(), but instead prints
"shutdown succeeded".
#include <stdio.h>
#include <stdlib.h>
#include <sys/socket.h>
int main(void)
{
int s;
s = socket(PF_INET, SOCK_STREAM, 0);
if (s == -1)
{
perror("socket");
exit(1);
}
if (shutdown(s, SHUT_RD) == -1)
perror("shutdown");
else
printf("shutdown succeeded\n");
return 0;
}
>Fix:
Check for SS_ISCONNECTED in soshutdown, and return ENOTCONN if it
is not set.
