FS#295 - UAC generates messages with a NULL body which failes in SANITY module check
User who did this - oren avraham (orenav)

Here is my code
$uac_req(method) = "REGISTER";
		$uac_req(ruri) = $sht(websocket=>$si:$sp:ruri);
		$uac_req(furi) = $sht(websocket=>$si:$sp:furi);
		$uac_req(turi) = $sht(websocket=>$si:$sp:turi);
		$uac_req(hdrs) = $sht(websocket=>$si:$sp:hdrs);
		if (uac_req_send() < 0)
			xlog("L_ERROR","Failed sending unregister request");

and also a code for debug the sanity check:
if (!sanity_check("2")) {
		xlog("SANITY: uri scheme\n");
		exit;
	}
 
 	if (!sanity_check("4")) {
		xlog("SANITY: no mininal set of required headers\n");
		exit;
	}
	
	if (!sanity_check("64")) {
		xlog("SANITY: cseq value\n");
		exit;
	}
	
	if (!sanity_check("32")) {
		xlog("SANITY: cseq method\n");
		exit;
	}
	
	if (!sanity_check("128")) {
		xlog("SANITY: content length: cl=$cl rb= $rb bs=$bs mb=$mb\n");
		exit;
	}
	
 	if (!sanity_check("256")) {
	/* the register contains an invalid expires value and is replied with a 400 */
		xlog("SANITY: invalid expires\n");
		exit;
	}
	
	if (!sanity_check("1024","7")) {
	/* the register contains an invalid expires value and is replied with a 400 */
		xlog("SANITY: bad uris\n");
		exit;
	}
	
	if(!sanity_check("1511", "7"))
	{
		xlog("Malformed SIP message from $si:$sp\n");
		exit;
	}

I generate the message from a saved register message, that i've altered its expired contact parameter to 0.
When the generated message is run within main_route it gets to the sanity check and fails with check no.128 and its $rb is null.

Hope it was helpfull..
