		CHANGES IN /rsvpd DIRECTORY

CHANGES IN RELEASE 4.2a4

rsvp.h:		INTEGRITY object
		Changed format to conform to new specs...
		- Timestamp based Sequence Number (NTP format, 64 bit).
		- Key Identifier field size increased to 64 bit.
		- Sender Address eliminated.
		- Uniform object type for both IPv4 and IPv6

rsvp_var.h:	KEY_ASSOC structure
		Table entry changed to reflect new INTEGRITY format.
		MIN_INTGR_SEQ_NO eliminated.

rsvp_main.c:	cfig_action()
		Neighbor (sender) address is no longer required and
		this command has been eliminated. sendkey and recvkey 
		IDs changed to a hex string (8 byte, 16 hex char) and 
		sender address eliminated. These changes have been 
		reflected in the rsvpd man page.

rsvp_print.c:	fmt_object()
		Changed to print the new INTGRITY object format.

rsvp_bord.c:	ntoh_object(), hton_object()
		Handle network and host formats of INTEGRITY.

rsvp_maps.c:	check_version_sum(), rsvp_map_packet()
		Allow both checksum and Integrity to be present.

rsvp_key.c:	Changes to correspond with the new MD5 draft...
		- Sender Address not required in INTEGRITY object
		- Key Identifier field increased to 64b
		- Sequence number generated using a combination of
		  timestamp and message counter
		- IPv4 and IPv6 integrity handled uniformly
		- Key selection procedure
		  sender:   virtual interface
		  receiver: keyid
		- Allow checksum to be present
		- Handle keys with same keyid
		- New replay protection algorithm (sans handshake)
		- Allow Sequence Numbers to wrap around

rsvp_path.c:	path_refresh()
		Incrementing of sequence number for an INTEGRITY key
		association moved from here to set_integrity(). Now 
		it applies to all message types.

*.c *.h		Updated RSRR interface to RSRR v2.  As a result:
		* rsvp_unicast.c is renamed to rsrr_unicast.c.
		* rsvp_rsrr.c is renamed to rsrr_rsrr.c.
		* rsrr.c is added.
		Changes to various files are intended to adapt to the
		new RSRR interface which will handle all of IPv4/IPv6
		unicast/multicast route queries for rsvpd.  All the
		previous calls to unicast_route() and Route_Query() is
		now handled by one single rsrr_route_query().  The
		details of RSRRv2 can be found in the Internet draft
		draft-ietf-rsvp-routing-02.txt.

		The definition of bitmap has changed from an unsigned
		long integer to an array of characters.  Consequently,
		the new bitmap has 64 bits and it can be changed by
		resetting the BMP_SIZE in rsvp_var.h if this turns out
		to be insufficient.  One example change is, dump_PSB() 
		now prints list of the outgoing interfaces instead of 
		an integer representation of the bitmap.

rsa_md5_global.h, rsa_md5c.c, rsa_md5c.h:
		Implemented as per RFC-1321 : The MD5 Message-Digest 
		Algorithm.		

rsa_hmac_md5.c, rsa_hmac_md5.h:
		Implemented as per RFC-2104 : HMAC: Keyed-Hashing 
		for Message Authentication.

rsa_md5_mddriver.c:
		Test vectors and routines for HMAC and MD5 calculations
		spread over the following Files :
		rsa_md5_global.h	RSAREF types and constants
		rsa_md5c.c		MD5 routines
		rsa_md5c.h		corresponding header
		rsa_hmac_md5.c		HMAC algorithm
		rsa_hmac_md5.h		corresponding header

rsvp_key.c:
		Properly interfaced the HMAC-MD5 algorithm with RSVP
		Integrity calculations. Integrity implementation tested
		for Resv, ResvTear, Path, PathTear.

rsvp_key.c:
		Function Modified: set_integrity() 
		Interface changed
		From :
			void set_integrity(struct packet *, int, 
		                   struct in_addr *);
		To   :
			void set_integrity(struct packet *, int, 
		                   net_addr *);

rsvp_key.c:
		Function Modified: load_key()
		Changes to prevent key buffer overflow when 
		given a MD5_LENG Byte key.
		From :
			strcpy((char *) (cp = ascikey), keystr);
		To   :
			strncpy((char *) (cp = ascikey), keystr, 2*MD5_LENG);

rsvp_maps.c:
		Functions Modified: check_version_sum(), 
				   rsvp_pkt_map(),  
				   rsvp_map_packet()
		Significant changes to perform integrity check 
		before converting byte order from NET to HOST. 
		The integrity object is pre-processed but care 	 
		is taken not to perform an extra pass over the 
		entire packet (except in rare cases)

rsvp_resv.c:
		Function Modified: accept_resv_tear()
		Changes in calculation of interface cause for 
		integrity calculation it matters whether the 
		resv_tear came from the API or over network.
		From :
			out_vif = hop_lih(pkt->rsvp_nhop);
		To   :
			out_vif = IsHopAPI(pkt->rsvp_nhop) ? 
		          api_num : hop_lih(pkt->rsvp_nhop);

rsvp_path.c:
		Function Modified: accept_path_tear()
		Changes to check that INTEGRITY was included if 
		it is required. Similar to accept_path()

rsvp_api.c, rsvp_api.h rapi_lib.c:
		Created a new api_addr structure to pass IP address
		data between RAPI library and the RSVP daemon.  Since
		the layout and size of a sockaddr_in* can vary on
		different operating systems, different OS versions, and
		depending on whether IPv6 support is available, we
		define and use an OS independent representation.  All
		fields of this new data structure by definition are in
		network byte order.

rsvp_api.c, rsvp_api.h:
		Major update of API upcall code. (1) When new RAPI
		session is registered, deliver any existing path state
		for it in an upcall; but don't send upcall if there is
		no path state, and don't send upcall to all matching
		RAPI sessions. (2) Make null PATH_EVENT upcall work
		(again) for path teardown. (3) Make WF RESV_EVENT
		upcall work (again). (4) Support API requests/responses
		in network byte order. (5) Advance to version 5 API but
		allow range of versions (currently 4 or 5).

rapi_lib.c:
		RAPI now sends out API request through UDP socket at
		port API_PORT when the attempt to send the request
		through UNIX domain socket fails.

rsvp_netio.c:
		TTL threshold for multicast forwarding is now enforced
		for forwarding multicast Path messages.

rsvp_resv.c:	Fix bug: Teardown of resv state was not resulting in null 
		RESV_EVENT upcall to API.

rsvp_resv.c:	Fix bug in freeing local copy of filter spec in 
		resv_refresh_PSB(). [Masanobu Yuhara, Fujitsu]

rapi_lib.c, rapi_fmt.c:
		Fix bugs in setting and printing break bits in Adspecs,
		and reversed parameters to strncpy().
		[Masanobu Yuhara, Fujitsu]

rtap_cmds.c:	Make parsing of CL flowspecs consistent with current
		int-serv spec (Peak Rate parm is required).
		[Masanobu Yuhara, Fujitsu]

rsvp_err.c:	Fix bug in blockade-state processing of ResvErr message
		for SE style [Masanobu Yuhara, Fujitsu]

rapi_lib.h, rsvp_intserv.h:
		Minor changes to align with expected OpenGroup RAPI
		standard: Define NON_IS_HOP macro, remove obsolete
		rapi_set_timo declaration.	

CHANGES IN RELEASE 4.2a3   February 27, 1998:

Makefile:	Added the NO_IPV6 macro to provide the ability to
		compile an IPv4 only version on an IPv6 capable
		machine.

rsvp_LLkern.c:	The argument to TC_init() was changed to pass to
		outgoing interface LIH.  It previously passed a file
		descriptor to a UDP socket used by the TC test stub
		code.

		Fixed bug which caused TC_DelFlowspec() to be called
		with an invalid handle. [Michael Zink , NIST]

*.c *.h		Init_Object() was changed to set the object size to the
		exact size of the specified ctype rather than the
		maximum of all ctypes.  IPv4 objects were being sent
		with IPv6 lengths in IPv6-capable version.

		Enumerations of the if_vec[] interface table test the
		type of the interface in addition to the address (phy
		or vif).

		IPv6 multicast membership requests now use the
		interface number rather than the address.
