isisd/ChangeLog

   1 2005-01-01 Hasso Tepper <hasso at quagga.net>
   2
   3         * isis_common.h, isisd.c, isis_pdu.c: Implement authentication in
   4           SNPs correctly - ie. make it conditional like it is in IOS.
   5
   6 2004-12-29 Hasso Tepper <hasso at quagga.net>
   7
   8         * isis_circuit.c, isis_csm.c, isis_zebra.c: Don't crash during
   9           interface up/down events. I'm not sure whether logic is correct
  10           though. Needs rethink anyway, seems. Replace if_is_up() with
  11           if_is_operative() and add some more.
  12
  13 2004-12-24 Hasso Tepper <hasso at quagga.net>
  14
  15         * *.c: zlog_* cleanup. Mostly changed level of debug messages to
  16           LOG_DEBUG.
  17
  18 2004-12-07 Andrew J. Schorr <ajschorr@alumni.princeton.edu>
  19

  21
  22 2004-12-03 Andrew J. Schorr <ajschorr@alumni.princeton.edu>
  23
  24         * isis_main.c: (sigint,sigterm) Use zlog_notice for termination message.
  25           (terminate) This function should be static, not global.
  26           (main) Use zlog_notice for startup announcement, and remove
  27           ifdef ZEBRA_VERSION.
  28
  29 2004-11-25 Hasso Tepper <hasso at quagga.net>
  30
  31         * isis_main.c: Make group to run as configurable.
  32
  33 2004-11-24 Andrew J. Schorr <ajschorr@alumni.princeton.edu>
  34
  35         * dict.c: Include "zassert.h" instead of <assert.h>.
  36
  37 2004-10-13 Hasso Tepper <hasso at quagga.net>
  38
  39         * isis_main.c: Initialize access list. Although we haven't route
  40           filtering yet, it's needed to limit access to vty.
  41
  42 2004-10-11 Hasso Tepper <hasso at quagga.net>
  43
  44         * isis_routemap.c, isisd.c: Make more strings const.
  45         * isisd.h: Make min_bcast_mtu unsigned.
  46
  47 2004-10-07 Hasso Tepper <hasso at quagga.net>
  48
  49         * *.[c|h]: Fix warnings: make strings const, signed -> unsigned,
  50           remove or comment out unused variables etc.
  51         * isis_lsp.c: Clean lsp_print_detail() a bit, add TE TLV's and
  52           removed old code.
  53         * isis_circuit.c: Remove old ip/ipv6 address commands code.
  54
  55 2004-10-03 Hasso Tepper <hasso at quagga.net>
  56
  57         * isis_zebra.c: Read router id related messages from zebra daemon.
  58         * isis_lsp.c: Use router id in IP address TLV in LSP's. It's how Junos
  59           routers behave as well.
  60         * isis_tlv.h: Export add_tlv() function.
  61
  62 2004-09-27 Hasso Tepper <hasso at quagga.net>
  63
  64         * isis_pdu.c: Fix accessing NULL found by valgrind.
  65
  66 2004-09-26 Hasso Tepper <hasso at quagga.net>
  67
  68         * isis_circuit.c: Fix previous commit. Don't schedule LSP regeneration
  69           and don't crash if circuit->area == NULL.
  70
  71 2004-09-26 Hasso Tepper <hasso at quagga.net>
  72
  73         * *.[c|h]: Fix a lot of compiler warnings.
  74         * isis_events.c: Remove isis_event_int_reach_change() function, as it
  75           doesn't make sense for now. Call lsp_regenerate_schedule() directly
  76           where needed.
  77
  78 2004-09-26 Hasso Tepper <hasso at quagga.net>
  79
  80         * isis_lsp.h: Cast-as-lvalue extension is deprecated and is not
  81           accpted any more in gcc-4.0.
  82
  83 2004-09-24 Hasso Tepper <hasso at quagga.net>
  84
  85         * isisd.c: thread_master *master is already defined in isis_main.c.
  86         * isis_misc.[c|h], isis_lsp.[c|h]: Move static variables out of
  87           header files.
  88
  89 2004-09-23 Hasso Tepper <hasso at quagga.net>
  90
  91         * *.[c|h]: list -> struct list *, listnode -> struct listnode *.
  92
  93 2004-09-21 LIU Xin <lx at ns.6test.edu.cn>
  94
  95         * isis_dr.c: Update dis_record of adjacencies when isisd becomes DIS.
  96
  97 2004-09-21 Hasso Tepper <hasso at quagga.net>
  98
  99         * isis_lsp.c: Put IPv4 prefixes into reachability TLVs, not
 100           addresses. Make IPv6 work with other prefix lengths than % 8 == 0.
 101
 102 2004-09-20 LIU Xin <lx at ns.6test.edu.cn>
 103
 104         * isis_dr.c, isis_events.c: Remove hello multiplier usage while
 105           scheduling DIS election.
 106         * isis_pdu.c: Don't call isis_event_dis_status_change() whenever
 107           l[1|2]_desig_is is different from hdr.lan_id.
 108
 109 2004-09-19 Hasso Tepper <hasso at quagga.net>
 110
 111         * isis_spf.h: Renamed t_spf_periodic to t_spf as it's not used to
 112           store pointer to periodic SPF thread only.
 113         * isis_spf.c: Cleaned up SPF threads schedule code. IPv4 and IPv6
 114           threads are independant now. Used macros wherever possible.
 115         * isis_lsp.c: Fixed bug in scheduling LSP regeneration.
 116
 117 2004-09-17 LIU Xin <lx at ns.6test.edu.cn>
 118
 119         * isis_circuit.c: According to RFC1142 the first DIS election will be
 120         started 2 * HelloTimer seconds after the initialization.
 121
 122 2004-09-15 Laurent Rabret <laurent.rabret at francetelecom.com>
 123
 124         * isis_pdu.c: Fix error in same subnet comparison. The previous
 125           algorithm only worked when netmask % 8 == 0.
 126         * isisd.c: Show domain and area passwords in configuration.
 127         * iso_checksum.c: Fixed error in the checksum calculation. The previous
 128           algorithm could produce a bad checksum if the 2 complement's vs 1
 129           complement's adaptation was required.
 130         * isis_pdu.c: Authentication in LSPs does not mean authentication in
 131           SNPs.
 132         * isis_tlv.c: Fix errors in password checking.
 133
 134 2004-09-14 Hasso Tepper <hasso at quagga.net>
 135
 136         * isis_circuit.c: Mostly cosmetical changes in isis_circuit_add_addr()
 137           and add calls to isis_event_int_reach_change(). Implement
 138           isis_circuit_del_addr(). Cancel t_run_dr threads is circuit goes
 139           down.
 140         * isis_events.c: Implement isis_event_int_reach_change(). I'm not sure
 141           yet how this stuff should work, but it allows be to start debug
 142           threads which act very weird at the moment.
 143         * isis_tlv.c: Much less verbose by default.
 144         * isis_zebra.c: Added extreme debugging output. Call connected_free()
 145           after isis_circuit_del_addr, not before.
 146         * isisd.conf.sample: Update it a little bit. 10000 seconds hello time
 147           was certainly too much IMHO.
 148
 149 2004-09-14 LIU Xin <lx at ns.6test.edu.cn>
 150
 151         * isis_pdu.c: Update l1_desig_is only if neighbor really is DIS.
 152
 153 2004-09-10 LIU Xin <lx at ns.6test.edu.cn>
 154
 155         * isis_pdu.c: Goto out only if no adjacency exist.
 156         * isis_circuit.c: Don't crash while executing "isis circuit-type"
 157           command if circuit exists, but circuit->area is still NULL.
 158         * isis_lsp.c: Set pointers to thread to NULL before initiating new
 159           thread in lsp_l1_refresh_pseudo(), lsp_l2_refresh_pseudo() and
 160           lsp_tick() functions.
 161
 162 2004-05-19 Laurent Rabret <laurent.rabret at francetelecom.com>
 163
 164         * isis_constants.h: change the ISIS Hello interval from 1 to 10 (cisco's
 165           default value).
 166         * isis_main.c: suppress a bad "#if 0 #endif" block for isis to be
 167           activated on startup.
 168         * isis_tlv.[c|h]: LSP recognition of the ISIS Graceful Restart LSP (not
 169           implemented yet).
 170
 171 2004-05-19 Rivo Nurges <rix at estpak.ee>
 172
 173         * *.c: Removing many useless net/ethernet.h includes and some tiny
 174           fixes to make it compile on NetBSD and OpenBSD.
 175
 176 2004-05-08 Paul Jakma <paul@dishone.st>
 177
 178         * isis_zebra.c: Sync with zclient changes.
 179
 180 2004-02-11 Hasso Tepper <hasso@estpak.ee>
 181   * many *.c files: Replace thread_add_xxx() and thread_cancel() with
 182     THREAD_XXX_ON and THREAD_XXX_OFF macros.
 183
 184 2004-01-27 Hasso Tepper <hasso@estpak.ee>
 185   * isis_circuit.c: Commented out "(no) ip address" commands so it doesn't
 186     confuse vtysh.
 187
 188 2003-12-31 Hasso Tepper <hasso@estpak.ee>
 189   * isis_dr.c: Fix some threads related bugs.
 190
 191 2003-12-23 Hasso Tepper <hasso@estpak.ee>
 192   Some fixes done by me and Cougar <cougar@random.ee>.
 193   * isis_adjacency.c: Two bugfixes by Cougar:
 194     After down state neigbour was deleted but not removed from neighbours list.
 195     Don't show random expire time during neighbour initialisation.
 196   * isis_circuit.c: Don't show interface addresses in config by Cougar.
 197   * isis_constants.h, isis_misc.c: Show other well-known NLPID names as well
 198     by Cougar.
 199   * isisd.c: Two tiny CLI fixes by me.
 200   * isis_lsp.c: Bugfix in lsp_print_detail() by Cougar.
 201     Show IPv4 external and IPv6 TLV's in "show isis database detail" by me.
 202   * isis_misc.c: Net address format fix by Cougar.
 203   * isis_spf.c: Dead loop fix in isis_spf_preload_tent() by Cougar
 204   * isis_zebra.c: Ignore distance when adding route to zebra for now by me.
 205   * isis_tlv.c: Parse external IPv4 TLV's correctly by me.
