isisd/ChangeLog

2004-09-24 Hasso Tepper <hasso at quagga.net>

	* isisd.c: thread_master *master is already defined in isis_main.c.
	* isis_misc.[c|h], isis_lsp.[c|h]: Move static variables out of
	  header files.

2004-09-23 Hasso Tepper <hasso at quagga.net>

	* *.[c|h]: list -> struct list *, listnode -> struct listnode *.

2004-09-21 LIU Xin <lx at ns.6test.edu.cn>

	* isis_dr.c: Update dis_record of adjacencies when isisd becomes DIS.

2004-09-21 Hasso Tepper <hasso at quagga.net>

	* isis_lsp.c: Put IPv4 prefixes into reachability TLVs, not
	  addresses. Make IPv6 work with other prefix lengths than % 8 == 0.

2004-09-20 LIU Xin <lx at ns.6test.edu.cn>

	* isis_dr.c, isis_events.c: Remove hello multiplier usage while
	  scheduling DIS election.
	* isis_pdu.c: Don't call isis_event_dis_status_change() whenever
	  l[1|2]_desig_is is different from hdr.lan_id.

2004-09-19 Hasso Tepper <hasso at quagga.net>

	* isis_spf.h: Renamed t_spf_periodic to t_spf as it's not used to
	  store pointer to periodic SPF thread only.
	* isis_spf.c: Cleaned up SPF threads schedule code. IPv4 and IPv6
	  threads are independant now. Used macros wherever possible.
	* isis_lsp.c: Fixed bug in scheduling LSP regeneration.

2004-09-17 LIU Xin <lx at ns.6test.edu.cn>
	
	* isis_circuit.c: According to RFC1142 the first DIS election will be
	started 2 * HelloTimer seconds after the initialization.

2004-09-15 Laurent Rabret <laurent.rabret at francetelecom.com>

	* isis_pdu.c: Fix error in same subnet comparison. The previous
	  algorithm only worked when netmask % 8 == 0.
	* isisd.c: Show domain and area passwords in configuration.
	* iso_checksum.c: Fixed error in the checksum calculation. The previous
	  algorithm could produce a bad checksum if the 2 complement's vs 1
	  complement's adaptation was required.
	* isis_pdu.c: Authentication in LSPs does not mean authentication in
	  SNPs.
	* isis_tlv.c: Fix errors in password checking.

2004-09-14 Hasso Tepper <hasso at quagga.net>

	* isis_circuit.c: Mostly cosmetical changes in isis_circuit_add_addr()
	  and add calls to isis_event_int_reach_change(). Implement
	  isis_circuit_del_addr(). Cancel t_run_dr threads is circuit goes
	  down.
	* isis_events.c: Implement isis_event_int_reach_change(). I'm not sure
	  yet how this stuff should work, but it allows be to start debug
	  threads which act very weird at the moment.
	* isis_tlv.c: Much less verbose by default.
	* isis_zebra.c: Added extreme debugging output. Call connected_free()
	  after isis_circuit_del_addr, not before.
	* isisd.conf.sample: Update it a little bit. 10000 seconds hello time
	  was certainly too much IMHO.

2004-09-14 LIU Xin <lx at ns.6test.edu.cn>

	* isis_pdu.c: Update l1_desig_is only if neighbor really is DIS.

2004-09-10 LIU Xin <lx at ns.6test.edu.cn>
	
	* isis_pdu.c: Goto out only if no adjacency exist.
	* isis_circuit.c: Don't crash while executing "isis circuit-type"
	  command if circuit exists, but circuit->area is still NULL.
	* isis_lsp.c: Set pointers to thread to NULL before initiating new
	  thread in lsp_l1_refresh_pseudo(), lsp_l2_refresh_pseudo() and
	  lsp_tick() functions.

2004-05-19 Laurent Rabret <laurent.rabret at francetelecom.com>

	* isis_constants.h: change the ISIS Hello interval from 1 to 10 (cisco's
	  default value).
	* isis_main.c: suppress a bad "#if 0 #endif" block for isis to be
	  activated on startup.
	* isis_tlv.[c|h]: LSP recognition of the ISIS Graceful Restart LSP (not
	  implemented yet).

2004-05-19 Rivo Nurges <rix at estpak.ee>

	* *.c: Removing many useless net/ethernet.h includes and some tiny
	  fixes to make it compile on NetBSD and OpenBSD.

2004-05-08 Paul Jakma <paul@dishone.st>

	* isis_zebra.c: Sync with zclient changes.

2004-02-11 Hasso Tepper <hasso@estpak.ee>
  * many *.c files: Replace thread_add_xxx() and thread_cancel() with
    THREAD_XXX_ON and THREAD_XXX_OFF macros.

2004-01-27 Hasso Tepper <hasso@estpak.ee>
  * isis_circuit.c: Commented out "(no) ip address" commands so it doesn't
    confuse vtysh.

2003-12-31 Hasso Tepper <hasso@estpak.ee>
  * isis_dr.c: Fix some threads related bugs.

2003-12-23 Hasso Tepper <hasso@estpak.ee>
  Some fixes done by me and Cougar <cougar@random.ee>.
  * isis_adjacency.c: Two bugfixes by Cougar:
    After down state neigbour was deleted but not removed from neighbours list.
    Don't show random expire time during neighbour initialisation.
  * isis_circuit.c: Don't show interface addresses in config by Cougar.
  * isis_constants.h, isis_misc.c: Show other well-known NLPID names as well
    by Cougar.
  * isisd.c: Two tiny CLI fixes by me.
  * isis_lsp.c: Bugfix in lsp_print_detail() by Cougar.
    Show IPv4 external and IPv6 TLV's in "show isis database detail" by me.
  * isis_misc.c: Net address format fix by Cougar.
  * isis_spf.c: Dead loop fix in isis_spf_preload_tent() by Cougar
  * isis_zebra.c: Ignore distance when adding route to zebra for now by me.
  * isis_tlv.c: Parse external IPv4 TLV's correctly by me.
