spurious setsockopt in telnetd

[Fernando RUIZ]

HI,
 Certainly the parameter '0' is not a good symbol.

if (setsockopt(des_socket,SOL_SOCKET,SO_REUSEADDR,&i,sizeof(i)) == -1) 
{           
	perror("telnetd:setsockopt(SO_REUSEADDR)");
	close(des_socket);
	rtems_task_delete(RTEMS_SELF);
};

If the function fails your server halts in next functions. 

"Address already in use"

This happens only when the server restarts quickly.

The code has been borrowed from an old server sample code.
Sorry.

See you.

Asunto: spurious setsockopt in telnetd


Hi,

telnetd.c:rtems_task_telnetd contains strange setsockopt call (4.6,
CVS, probably all versions):

  setsockopt(des_socket,SOL_SOCKET,0,&i,sizeof(i));

In theory this call should always fail. Is this a bug, or some
undocumented setsockopt feature?
