I'm experimenting with IP options and have added the following to the
file object.
void file_get_ip_options(INT32 args) {
char buffer[44];
socklen_t len = sizeof(buffer);
int ret;
pop_n_elems(args);
ret = getsockopt(FD, IPPROTO_IP, IP_OPTIONS, buffer, &len);
if(ret!=0)
{
push_int(0);
return;
}
push_string( make_shared_binary_string( buffer, len ) );
}
void file_set_ip_options(INT32 args) {
int ret;
if(args!=1 || TYPEOF(Pike_sp[-args]) != PIKE_T_STRING)
Pike_error("Illegal arguments to set_ip_options.\n");
ret = setsockopt(FD, IPPROTO_IP, IP_OPTIONS, Pike_sp[-args].u.string->str,
Pike_sp[-args].u.string->len);
pop_n_elems(args);
push_int( ret==0 );
}
I can successfully set the NOP IP options with
Stdio.File f = Stdio.File();
f->open_socket();
f->set_ip_options("\1");
and can see it set in wireshark. However, I'm unable to read it out on
the server side. Is it my poor understanding of C or of network code
that is the problem?
