isisd/ChangeLog

   1 2005-09-26 Hasso Tepper <hasso at quagga.net>
   2
   3         * isis_tlv.[ch]: New function tlv_add_in_addr() to put just one IPv4
   4           address into TLV. Used for IPv4 address TLV (in case of LSP) and TE
   5           router ID TLV.
   6         * isis_lsp.c: Use tlv_add_in_addr() and include router ID in LSP.
   7
   8 2005-09-26 Hasso Tepper <hasso at quagga.net>
   9
  10         * isis_lsp.c: Support for originating TE IS and IPv4 TLV's. No any sub
  11           TLV handling yet.
  12
  13 2005-09-26 Hasso Tepper <hasso at quagga.net>
  14
  15         * isis_tlv.[ch]: Two new functions - tlv_add_te_is_neighs() and
  16           tlv_add_te_ipv4_reachs() to handle TLV's with new metric. None of
  17           them handle sub TLVs though for now.
  18
  19 2005-09-26 Hasso Tepper <hasso at quagga.net>
  20
  21         * isis_circuit.[ch]: Some preliminary support for specifying wide
  22           circuit metrics. Needs more thinking though, but should do for now.
  23
  24 2005-09-26 Hasso Tepper <hasso at quagga.net>
  25
  26         * isisd.[ch]: Introduce oldmetric flag for area and transition
  27           metricstyle command. With metricstyle wide only extended TLVs
  28           should be used.
  29
  30 2005-09-25 Hasso Tepper <hasso at quagga.net>
  31
  32         * dict.[ch]: Revert all nonfunctional changes. It's external module
  33           imported from kazlib and it's better not to screw it - there is
  34           theoretical chance that we might want to merge changes from upstream
  35           at some point. Also avoid the loss of info about upstream version
  36           (rcsid).
  37
  38 2005-09-21 Hasso Tepper <hasso at quagga.net>
  39
  40         * isis_route.c: Fix output of nexthops in case of extreme debug.
  41
  42 2005-09-19 Hasso Tepper <hasso at quagga.net>
  43
  44         * isis_lsp.c, isis_pdu.c, isis_spf.c: Remove some old unused code.
  45
  46 2005-09-19 Hasso Tepper <hasso at quagga.net>
  47
  48         * isis_lsp.c: Better output of detailed LSP printout and fixed TE IPv4
  49           reachibility metric display.
  50
  51 2005-09-19 Hasso Tepper <hasso at quagga.net>
  52
  53         * isis_tlv.h: Cleanup comment about TLVs we should support, remove info
  54           about useless (in sense of IP(v6)) TLVs.
  55
  56 2005-09-19 Hasso Tepper <hasso at quagga.net>
  57
  58         * isis_lsp.h: Added backpointer to the area from LSP. For now it's used
  59           only in generated topology LSPs.
  60         * isisd.[ch]: Cleanup CLI commands related to topology generation and
  61           added command to specify base fo dynamic hostname for topology LSPs.
  62         * isis_lsp.c: Rewrite almost all code related to generation topology
  63           LSPs (top_lsp_refresh(), generate_topology_lsps() and
  64           build_topology_lsp_data() functions). Topology is connected to own
  65           LSP now (lsp_build_nonpseudo). Commented out lsppdu_realloc
  66           functions, it's not used any more hopefully.
  67
  68 2005-09-18 Hasso Tepper <hasso at quagga.net>
  69
  70         * isis_lsp.c (lsp_update): Fix previous commit - manipulate the right
  71           database and only if LSP is really in the database (sanity check).
  72
  73 2005-09-16 Hasso Tepper <hasso at quagga.net>
  74
  75         * isis_lsp.c (lsp_update): Remove LSP from database before updating
  76           its data and put it back after. Database entry MUST contain at least
  77           correct pointers to the sysid to get correct compare results.
  78         * isis_lsp.[ch], isis_pdu.c: Pass level to the lsp_update() function.
  79
  80 2005-09-05 Hasso Tepper <hasso at quagga.net>
  81
  82         * *.c: Try to be less verbose by default (without any debug options
  83           on).
  84         * isis_lsp.c (lsp_build_nonpseudo): Use stream_reset() instead of
  85           touching endp directly.
  86         * isis_lsp.c (lsp_build_pseudo): Ditto.
  87
  88 2005-09-03 Hasso Tepper <hasso at quagga.net>
  89
  90         * isis_lsp.c: Yet another regression introduced by stream cleanup.
  91           Similar fix to the one commited to lsp_build_nonpseudo() some days
  92           ago.
  93
  94 2005-09-01 Hasso Tepper <hasso at quagga.net>
  95
  96         * isis_lsp.c: Less TLV leaking.
  97
  98 2005-09-01 Hasso Tepper <hasso at quagga.net>
  99
 100         * random.c, spgrid.[ch]: Fix warnings with hope that I didn't broke
 101           anything. These floats to longs and vice versa casts are starnge
 102           indeed.
 103         * isis_pdu.c: As we don't use %z for size_t for now because we support
 104           older compilers, cast them to unsigned long.
 105
 106 2005-09-01 Hasso Tepper <hasso at quagga.net>
 107
 108         * isis_adjacency.c, isis_lsp.c, isisd.c: Replace XMALLOC && memset
 109           with XCALLOC.
 110         * isis_lsp.c (lsp_build_pseudo): Fix adding ES neighbour.
 111         * isis_tlv.c: More compact free_tlvs() function.
 112         * isis_lsp.c (lsp_build_nonpseudo) : Try to fix one more regression
 113           introduced by stream cleanup. Seek endp to the right place before
 114           starting to fill stream with TLVs.
 115
 116 2005-08-16 Hasso Tepper <hasso at quagga.net>
 117
 118         * isis_misc.[ch]: Fix some warnings, making some strings const.
 119
 120 2005-08-10 Hasso Tepper <hasso at quagga.net>
 121
 122         * topology/spgrid.c: MAXLONG is deprecated, use LONG_MAX instead.
 123           values.h, where MAXLONG is defined, is deprecated as well.
 124
 125 2005-05-26 Yossi Boaron <Yossi.Boaron@veraznetworks.com>
 126
 127         * isis_dr.c: Fix copy&paste error in isis_dr_resign().
 128
 129 2005-05-25 Paul Jakma <paul@dishone.st>
 130
 131         * isisd.c: (show_isis_generated_topology) change to _RO version
 132           of list macro. remove the extra listnode variable. one of the
 133           macros had had incorrect number of arguments.
 134
 135 2005-05-03 Paul Jakma <paul@dishone.st>
 136
 137         * (general) More cleaning up of stream abuse, isisd should be
 138           back to previous functionality. Replace various XMALLOC+memset's
 139           with XCALLOC
 140         * isis_tlv.c: (tlv_add_padding) use stream_put to clear the stream
 141           rather than forward endp, as isisd reuses streams.
 142         * isis_pdu.c: (process_lsp) cleanup direct reference to stream endp
 143           (send_lsp) manual copy of a stream cleaned up to use stream_copy.
 144         * isis_network.c: (isis_recv_pdu_bcast) replace direct memcpy with
 145           stream_write
 146           (isis_recv_pdu_p2p) replace recvfrom directly into stream with
 147           stream_recvfrom. Remove dangerous and now unneeded manual update
 148           of endp.
 149           (isis_recv_pdu_bcast / non-GNU_LINUX) Replace direct memcpy with
 150           stream_write.
 151           (isis_recv_pdu_p2p) replace read direct into stream with
 152           stream_read_try, and hence remove the manual update of endp.
 153         * isis_lsp.c: (lsp_update_data) manual stream dup replaced with
 154           stream_dup.
 155           (lsppdu_realloc) mempcy into stream data replaced with stream_put.
 156           (lsp_build_nonpseudo) remove mysterious stream_forward_endp's -
 157           which were originally stream_set_putp - shouldn't be needed
 158           now that all the manual fiddling of private stream data has been
 159           corrected.
 160           (build_topology_lsp_data) remove unneeded twiddling of endp,
 161           appears to be due to lsppdu_realloc(), but it appears to sort of
 162           do the right thing wrt streams.
 163
 164 2005-04-15 Paul Jakma <paul@dishone.st>
 165
 166         * topology/Makefile.am: random.c is a source of libtopology, so list
 167           it.
 168
 169 2005-04-12 Hasso Tepper <hasso at quagga.net>
 170
 171         * isis_adjacency.c: Fix typo introduced with listloop cleanup.
 172
 173 2005-04-11 Andrew J. Schorr <ajschorr@alumni.princeton.edu>
 174
 175         * isis_zebra.h (isis_zebra_finish): Remove declaration of unused
 176           function.
 177         * isis_zebra.c (isis_zebra_route_add_ipv4): Call zclient_send_message
 178           to send the message to zebra instead of calling writen directly, since
 179           zclient_send_message understands non-blocking I/O and will manage
 180           the buffer queue appropriately.
 181           (isis_zebra_finish): Remove unused function, particularly since
 182           the zclient_free function has been removed.
 183
 184 2005-04-10 Paul Jakma <paul@dishone.st>
 185
 186         * Makefile.am: topology should not be a conditional SUBDIR,
 187           otherwise make dist breaks.
 188         * topology/Makefile.am: remove EXTRA_DIST of files which dont
 189           exist in that directory, broke make dist.
 190         * isisd.c: (show_isis_generated_topology_cmd) convert LIST_LOOP
 191         * isis_lsp.c: (generate_topology_lsps) ditto
 192           (build_topology_lsp_data) ditto
 193
 194 2005-04-02 Andrew J. Schorr <ajschorr@alumni.princeton.edu>
 195
 196         * isis_zebra.c: (isis_zebra_if_del) Must use if_lookup_by_name_len.
 197
 198 2005-04-02 Hasso Tepper <hasso at quagga.net>
 199
 200         * Makefile.am: Variables to handle conditonal compiling of topology
 201           generator code.
 202         * isis_lsp.c: lsppdu_realloc() is used by topology generator.
 203         * isisd.c: Rename show_isis_topology_cmd to not conflict the one in
 204           the isis_spf.c.
 205         * isisd.h: Remove TOPOLOGY_GENERATE define, it will be defined in
 206           toplevel config.h if topology generator is enabled.
 207         * topology/Makefile.am: Handle the libtoolized Quagga libraries.
 208
 209 2005-04-02 Andrew J. Schorr <ajschorr@alumni.princeton.edu>
 210
 211         * isis_zebra.c: (isis_zebra_if_del) Call if_delete_retain instead
 212           of if_delete, since it is generally not safe to remove interface
 213           structures.  After deleting, set ifp->ifindex to IFINDEX_INTERNAL.
 214           (zebra_interface_if_lookup) Tighten up code.
 215
 216 2005-03-07 Michael Sandee <voidptr@voidptr.sboost.org>
 217
 218         * isis_spf.c: host.name might be NULL.
 219
 220 2005-02-23 Andrew J. Schorr <ajschorr@alumni.princeton.edu>
 221
 222         * isis_main.c: (reload) Call vty_reset instead of vty_finish (both
 223           functions were exactly the same).
 224
 225 2005-01-18 Hasso Tepper <hasso at quagga.net>
 226
 227         * *.c: Changed many functions to static. Some commented out
 228           functions and some tiny related fixes. No functional changes.
 229
 230 2005-01-01 Hasso Tepper <hasso at quagga.net>
 231
 232         * isis_common.h, isisd.c, isis_pdu.c: Implement authentication in
 233           SNPs correctly - ie. make it conditional like it is in IOS.
 234
 235 2004-12-29 Hasso Tepper <hasso at quagga.net>
 236
 237         * isis_circuit.c, isis_csm.c, isis_zebra.c: Don't crash during
 238           interface up/down events. I'm not sure whether logic is correct
 239           though. Needs rethink anyway, seems. Replace if_is_up() with
 240           if_is_operative() and add some more.
 241
 242 2004-12-24 Hasso Tepper <hasso at quagga.net>
 243
 244         * *.c: zlog_* cleanup. Mostly changed level of debug messages to
 245           LOG_DEBUG.
 246
 247 2004-12-07 Andrew J. Schorr <ajschorr@alumni.princeton.edu>
 248
 249         * isis_main.c: (main) The 2nd argument to openzlog has been removed.
 250
 251 2004-12-03 Andrew J. Schorr <ajschorr@alumni.princeton.edu>
 252
 253         * isis_main.c: (sigint,sigterm) Use zlog_notice for termination message.
 254           (terminate) This function should be static, not global.
 255           (main) Use zlog_notice for startup announcement, and remove
 256           ifdef ZEBRA_VERSION.
 257
 258 2004-11-25 Hasso Tepper <hasso at quagga.net>
 259
 260         * isis_main.c: Make group to run as configurable.
 261
 262 2004-11-24 Andrew J. Schorr <ajschorr@alumni.princeton.edu>
 263
 264         * dict.c: Include "zassert.h" instead of <assert.h>.
 265
 266 2004-10-13 Hasso Tepper <hasso at quagga.net>
 267
 268         * isis_main.c: Initialize access list. Although we haven't route
 269           filtering yet, it's needed to limit access to vty.
 270
 271 2004-10-11 Hasso Tepper <hasso at quagga.net>
 272
 273         * isis_routemap.c, isisd.c: Make more strings const.
 274         * isisd.h: Make min_bcast_mtu unsigned.
 275
 276 2004-10-07 Hasso Tepper <hasso at quagga.net>
 277
 278         * *.[c|h]: Fix warnings: make strings const, signed -> unsigned,
 279           remove or comment out unused variables etc.
 280         * isis_lsp.c: Clean lsp_print_detail() a bit, add TE TLV's and
 281           removed old code.
 282         * isis_circuit.c: Remove old ip/ipv6 address commands code.
 283
 284 2004-10-03 Hasso Tepper <hasso at quagga.net>
 285
 286         * isis_zebra.c: Read router id related messages from zebra daemon.
 287         * isis_lsp.c: Use router id in IP address TLV in LSP's. It's how Junos
 288           routers behave as well.
 289         * isis_tlv.h: Export add_tlv() function.
 290
 291 2004-09-27 Hasso Tepper <hasso at quagga.net>
 292
 293         * isis_pdu.c: Fix accessing NULL found by valgrind.
 294
 295 2004-09-26 Hasso Tepper <hasso at quagga.net>
 296
 297         * isis_circuit.c: Fix previous commit. Don't schedule LSP regeneration
 298           and don't crash if circuit->area == NULL.
 299
 300 2004-09-26 Hasso Tepper <hasso at quagga.net>
 301
 302         * *.[c|h]: Fix a lot of compiler warnings.
 303         * isis_events.c: Remove isis_event_int_reach_change() function, as it
 304           doesn't make sense for now. Call lsp_regenerate_schedule() directly
 305           where needed.
 306
 307 2004-09-26 Hasso Tepper <hasso at quagga.net>
 308
 309         * isis_lsp.h: Cast-as-lvalue extension is deprecated and is not
 310           accpted any more in gcc-4.0.
 311
 312 2004-09-24 Hasso Tepper <hasso at quagga.net>
 313
 314         * isisd.c: thread_master *master is already defined in isis_main.c.
 315         * isis_misc.[c|h], isis_lsp.[c|h]: Move static variables out of
 316           header files.
 317
 318 2004-09-23 Hasso Tepper <hasso at quagga.net>
 319
 320         * *.[c|h]: list -> struct list *, listnode -> struct listnode *.
 321
 322 2004-09-21 LIU Xin <lx at ns.6test.edu.cn>
 323
 324         * isis_dr.c: Update dis_record of adjacencies when isisd becomes DIS.
 325
 326 2004-09-21 Hasso Tepper <hasso at quagga.net>
 327
 328         * isis_lsp.c: Put IPv4 prefixes into reachability TLVs, not
 329           addresses. Make IPv6 work with other prefix lengths than % 8 == 0.
 330
 331 2004-09-20 LIU Xin <lx at ns.6test.edu.cn>
 332
 333         * isis_dr.c, isis_events.c: Remove hello multiplier usage while
 334           scheduling DIS election.
 335         * isis_pdu.c: Don't call isis_event_dis_status_change() whenever
 336           l[1|2]_desig_is is different from hdr.lan_id.
 337
 338 2004-09-19 Hasso Tepper <hasso at quagga.net>
 339
 340         * isis_spf.h: Renamed t_spf_periodic to t_spf as it's not used to
 341           store pointer to periodic SPF thread only.
 342         * isis_spf.c: Cleaned up SPF threads schedule code. IPv4 and IPv6
 343           threads are independant now. Used macros wherever possible.
 344         * isis_lsp.c: Fixed bug in scheduling LSP regeneration.
 345
 346 2004-09-17 LIU Xin <lx at ns.6test.edu.cn>
 347
 348         * isis_circuit.c: According to RFC1142 the first DIS election will be
 349         started 2 * HelloTimer seconds after the initialization.
 350
 351 2004-09-15 Laurent Rabret <laurent.rabret at francetelecom.com>
 352
 353         * isis_pdu.c: Fix error in same subnet comparison. The previous
 354           algorithm only worked when netmask % 8 == 0.
 355         * isisd.c: Show domain and area passwords in configuration.
 356         * iso_checksum.c: Fixed error in the checksum calculation. The previous
 357           algorithm could produce a bad checksum if the 2 complement's vs 1
 358           complement's adaptation was required.
 359         * isis_pdu.c: Authentication in LSPs does not mean authentication in
 360           SNPs.
 361         * isis_tlv.c: Fix errors in password checking.
 362
 363 2004-09-14 Hasso Tepper <hasso at quagga.net>
 364
 365         * isis_circuit.c: Mostly cosmetical changes in isis_circuit_add_addr()
 366           and add calls to isis_event_int_reach_change(). Implement
 367           isis_circuit_del_addr(). Cancel t_run_dr threads is circuit goes
 368           down.
 369         * isis_events.c: Implement isis_event_int_reach_change(). I'm not sure
 370           yet how this stuff should work, but it allows be to start debug
 371           threads which act very weird at the moment.
 372         * isis_tlv.c: Much less verbose by default.
 373         * isis_zebra.c: Added extreme debugging output. Call connected_free()
 374           after isis_circuit_del_addr, not before.
 375         * isisd.conf.sample: Update it a little bit. 10000 seconds hello time
 376           was certainly too much IMHO.
 377
 378 2004-09-14 LIU Xin <lx at ns.6test.edu.cn>
 379
 380         * isis_pdu.c: Update l1_desig_is only if neighbor really is DIS.
 381
 382 2004-09-10 LIU Xin <lx at ns.6test.edu.cn>
 383
 384         * isis_pdu.c: Goto out only if no adjacency exist.
 385         * isis_circuit.c: Don't crash while executing "isis circuit-type"
 386           command if circuit exists, but circuit->area is still NULL.
 387         * isis_lsp.c: Set pointers to thread to NULL before initiating new
 388           thread in lsp_l1_refresh_pseudo(), lsp_l2_refresh_pseudo() and
 389           lsp_tick() functions.
 390
 391 2004-05-19 Laurent Rabret <laurent.rabret at francetelecom.com>
 392
 393         * isis_constants.h: change the ISIS Hello interval from 1 to 10 (cisco's
 394           default value).
 395         * isis_main.c: suppress a bad "#if 0 #endif" block for isis to be
 396           activated on startup.
 397         * isis_tlv.[c|h]: LSP recognition of the ISIS Graceful Restart LSP (not
 398           implemented yet).
 399
 400 2004-05-19 Rivo Nurges <rix at estpak.ee>
 401
 402         * *.c: Removing many useless net/ethernet.h includes and some tiny
 403           fixes to make it compile on NetBSD and OpenBSD.
 404
 405 2004-05-08 Paul Jakma <paul@dishone.st>
 406
 407         * isis_zebra.c: Sync with zclient changes.
 408
 409 2004-02-11 Hasso Tepper <hasso@estpak.ee>
 410   * many *.c files: Replace thread_add_xxx() and thread_cancel() with
 411     THREAD_XXX_ON and THREAD_XXX_OFF macros.
 412
 413 2004-01-27 Hasso Tepper <hasso@estpak.ee>
 414   * isis_circuit.c: Commented out "(no) ip address" commands so it doesn't
 415     confuse vtysh.
 416
 417 2003-12-31 Hasso Tepper <hasso@estpak.ee>
 418   * isis_dr.c: Fix some threads related bugs.
 419
 420 2003-12-23 Hasso Tepper <hasso@estpak.ee>
 421   Some fixes done by me and Cougar <cougar@random.ee>.
 422   * isis_adjacency.c: Two bugfixes by Cougar:
 423     After down state neigbour was deleted but not removed from neighbours list.
 424     Don't show random expire time during neighbour initialisation.
 425   * isis_circuit.c: Don't show interface addresses in config by Cougar.
 426   * isis_constants.h, isis_misc.c: Show other well-known NLPID names as well
 427     by Cougar.
 428   * isisd.c: Two tiny CLI fixes by me.
 429   * isis_lsp.c: Bugfix in lsp_print_detail() by Cougar.
 430     Show IPv4 external and IPv6 TLV's in "show isis database detail" by me.
 431   * isis_misc.c: Net address format fix by Cougar.
 432   * isis_spf.c: Dead loop fix in isis_spf_preload_tent() by Cougar
 433   * isis_zebra.c: Ignore distance when adding route to zebra for now by me.
 434   * isis_tlv.c: Parse external IPv4 TLV's correctly by me.
