isisd/ChangeLog

   1 2005-09-01 Hasso Tepper <hasso at quagga.net>
   2
   3         * isis_lsp.c: Less TLV leaking.
   4
   5 2005-09-01 Hasso Tepper <hasso at quagga.net>
   6
   7         * random.c, spgrid.[ch]: Fix warnings with hope that I didn't broke
   8           anything. These floats to longs and vice versa casts are starnge
   9           indeed.
  10         * isis_pdu.c: As we don't use %z for size_t for now because we support
  11           older compilers, cast them to unsigned long.
  12
  13 2005-09-01 Hasso Tepper <hasso at quagga.net>
  14
  15         * isis_adjacency.c, isis_lsp.c, isisd.c: Replace XMALLOC && memset
  16           with XCALLOC.
  17         * isis_lsp.c (lsp_build_pseudo): Fix adding ES neighbour.
  18         * isis_tlv.c: More compact free_tlvs() function.
  19         * isis_lsp.c (lsp_build_nonpseudo) : Try to fix one more regression
  20           introduced by stream cleanup. Seek endp to the right place before
  21           starting to fill stream with TLVs.
  22
  23 2005-08-16 Hasso Tepper <hasso at quagga.net>
  24
  25         * isis_misc.[ch]: Fix some warnings, making some strings const.
  26
  27 2005-08-10 Hasso Tepper <hasso at quagga.net>
  28
  29         * topology/spgrid.c: MAXLONG is deprecated, use LONG_MAX instead.
  30           values.h, where MAXLONG is defined, is deprecated as well.
  31
  32 2005-05-26 Yossi Boaron <Yossi.Boaron@veraznetworks.com>
  33
  34         * isis_dr.c: Fix copy&paste error in isis_dr_resign().
  35
  36 2005-05-25 Paul Jakma <paul@dishone.st>
  37
  38         * isisd.c: (show_isis_generated_topology) change to _RO version
  39           of list macro. remove the extra listnode variable. one of the
  40           macros had had incorrect number of arguments.
  41
  42 2005-05-03 Paul Jakma <paul@dishone.st>
  43
  44         * (general) More cleaning up of stream abuse, isisd should be
  45           back to previous functionality. Replace various XMALLOC+memset's
  46           with XCALLOC
  47         * isis_tlv.c: (tlv_add_padding) use stream_put to clear the stream
  48           rather than forward endp, as isisd reuses streams.
  49         * isis_pdu.c: (process_lsp) cleanup direct reference to stream endp
  50           (send_lsp) manual copy of a stream cleaned up to use stream_copy.
  51         * isis_network.c: (isis_recv_pdu_bcast) replace direct memcpy with
  52           stream_write
  53           (isis_recv_pdu_p2p) replace recvfrom directly into stream with
  54           stream_recvfrom. Remove dangerous and now unneeded manual update
  55           of endp.
  56           (isis_recv_pdu_bcast / non-GNU_LINUX) Replace direct memcpy with
  57           stream_write.
  58           (isis_recv_pdu_p2p) replace read direct into stream with
  59           stream_read_try, and hence remove the manual update of endp.
  60         * isis_lsp.c: (lsp_update_data) manual stream dup replaced with
  61           stream_dup.
  62           (lsppdu_realloc) mempcy into stream data replaced with stream_put.
  63           (lsp_build_nonpseudo) remove mysterious stream_forward_endp's -
  64           which were originally stream_set_putp - shouldn't be needed
  65           now that all the manual fiddling of private stream data has been
  66           corrected.
  67           (build_topology_lsp_data) remove unneeded twiddling of endp,
  68           appears to be due to lsppdu_realloc(), but it appears to sort of
  69           do the right thing wrt streams.
  70
  71 2005-04-15 Paul Jakma <paul@dishone.st>
  72
  73         * topology/Makefile.am: random.c is a source of libtopology, so list
  74           it.
  75
  76 2005-04-12 Hasso Tepper <hasso at quagga.net>
  77
  78         * isis_adjacency.c: Fix typo introduced with listloop cleanup.
  79
  80 2005-04-11 Andrew J. Schorr <ajschorr@alumni.princeton.edu>
  81
  82         * isis_zebra.h (isis_zebra_finish): Remove declaration of unused
  83           function.
  84         * isis_zebra.c (isis_zebra_route_add_ipv4): Call zclient_send_message
  85           to send the message to zebra instead of calling writen directly, since
  86           zclient_send_message understands non-blocking I/O and will manage
  87           the buffer queue appropriately.
  88           (isis_zebra_finish): Remove unused function, particularly since
  89           the zclient_free function has been removed.
  90
  91 2005-04-10 Paul Jakma <paul@dishone.st>
  92
  93         * Makefile.am: topology should not be a conditional SUBDIR,
  94           otherwise make dist breaks.
  95         * topology/Makefile.am: remove EXTRA_DIST of files which dont
  96           exist in that directory, broke make dist.
  97         * isisd.c: (show_isis_generated_topology_cmd) convert LIST_LOOP
  98         * isis_lsp.c: (generate_topology_lsps) ditto
  99           (build_topology_lsp_data) ditto
 100
 101 2005-04-02 Andrew J. Schorr <ajschorr@alumni.princeton.edu>
 102
 103         * isis_zebra.c: (isis_zebra_if_del) Must use if_lookup_by_name_len.
 104
 105 2005-04-02 Hasso Tepper <hasso at quagga.net>
 106
 107         * Makefile.am: Variables to handle conditonal compiling of topology
 108           generator code.
 109         * isis_lsp.c: lsppdu_realloc() is used by topology generator.
 110         * isisd.c: Rename show_isis_topology_cmd to not conflict the one in
 111           the isis_spf.c.
 112         * isisd.h: Remove TOPOLOGY_GENERATE define, it will be defined in
 113           toplevel config.h if topology generator is enabled.
 114         * topology/Makefile.am: Handle the libtoolized Quagga libraries.
 115
 116 2005-04-02 Andrew J. Schorr <ajschorr@alumni.princeton.edu>
 117
 118         * isis_zebra.c: (isis_zebra_if_del) Call if_delete_retain instead
 119           of if_delete, since it is generally not safe to remove interface
 120           structures.  After deleting, set ifp->ifindex to IFINDEX_INTERNAL.
 121           (zebra_interface_if_lookup) Tighten up code.
 122
 123 2005-03-07 Michael Sandee <voidptr@voidptr.sboost.org>
 124
 125         * isis_spf.c: host.name might be NULL.
 126
 127 2005-02-23 Andrew J. Schorr <ajschorr@alumni.princeton.edu>
 128
 129         * isis_main.c: (reload) Call vty_reset instead of vty_finish (both
 130           functions were exactly the same).
 131
 132 2005-01-18 Hasso Tepper <hasso at quagga.net>
 133
 134         * *.c: Changed many functions to static. Some commented out
 135           functions and some tiny related fixes. No functional changes.
 136
 137 2005-01-01 Hasso Tepper <hasso at quagga.net>
 138
 139         * isis_common.h, isisd.c, isis_pdu.c: Implement authentication in
 140           SNPs correctly - ie. make it conditional like it is in IOS.
 141
 142 2004-12-29 Hasso Tepper <hasso at quagga.net>
 143
 144         * isis_circuit.c, isis_csm.c, isis_zebra.c: Don't crash during
 145           interface up/down events. I'm not sure whether logic is correct
 146           though. Needs rethink anyway, seems. Replace if_is_up() with
 147           if_is_operative() and add some more.
 148
 149 2004-12-24 Hasso Tepper <hasso at quagga.net>
 150
 151         * *.c: zlog_* cleanup. Mostly changed level of debug messages to

 157
 158 2004-12-03 Andrew J. Schorr <ajschorr@alumni.princeton.edu>
 159
 160         * isis_main.c: (sigint,sigterm) Use zlog_notice for termination message.
 161           (terminate) This function should be static, not global.
 162           (main) Use zlog_notice for startup announcement, and remove
 163           ifdef ZEBRA_VERSION.
 164
 165 2004-11-25 Hasso Tepper <hasso at quagga.net>
 166
 167         * isis_main.c: Make group to run as configurable.
 168
 169 2004-11-24 Andrew J. Schorr <ajschorr@alumni.princeton.edu>
 170
 171         * dict.c: Include "zassert.h" instead of <assert.h>.
 172
 173 2004-10-13 Hasso Tepper <hasso at quagga.net>
 174
 175         * isis_main.c: Initialize access list. Although we haven't route
 176           filtering yet, it's needed to limit access to vty.
 177
 178 2004-10-11 Hasso Tepper <hasso at quagga.net>
 179
 180         * isis_routemap.c, isisd.c: Make more strings const.
 181         * isisd.h: Make min_bcast_mtu unsigned.
 182
 183 2004-10-07 Hasso Tepper <hasso at quagga.net>
 184
 185         * *.[c|h]: Fix warnings: make strings const, signed -> unsigned,
 186           remove or comment out unused variables etc.
 187         * isis_lsp.c: Clean lsp_print_detail() a bit, add TE TLV's and
 188           removed old code.
 189         * isis_circuit.c: Remove old ip/ipv6 address commands code.
 190
 191 2004-10-03 Hasso Tepper <hasso at quagga.net>
 192
 193         * isis_zebra.c: Read router id related messages from zebra daemon.
 194         * isis_lsp.c: Use router id in IP address TLV in LSP's. It's how Junos
 195           routers behave as well.
 196         * isis_tlv.h: Export add_tlv() function.
 197
 198 2004-09-27 Hasso Tepper <hasso at quagga.net>
 199
 200         * isis_pdu.c: Fix accessing NULL found by valgrind.
 201
 202 2004-09-26 Hasso Tepper <hasso at quagga.net>
 203
 204         * isis_circuit.c: Fix previous commit. Don't schedule LSP regeneration
 205           and don't crash if circuit->area == NULL.
 206
 207 2004-09-26 Hasso Tepper <hasso at quagga.net>
 208
 209         * *.[c|h]: Fix a lot of compiler warnings.
 210         * isis_events.c: Remove isis_event_int_reach_change() function, as it
 211           doesn't make sense for now. Call lsp_regenerate_schedule() directly
 212           where needed.
 213
 214 2004-09-26 Hasso Tepper <hasso at quagga.net>
 215
 216         * isis_lsp.h: Cast-as-lvalue extension is deprecated and is not
 217           accpted any more in gcc-4.0.
 218
 219 2004-09-24 Hasso Tepper <hasso at quagga.net>
 220
 221         * isisd.c: thread_master *master is already defined in isis_main.c.
 222         * isis_misc.[c|h], isis_lsp.[c|h]: Move static variables out of
 223           header files.
 224
 225 2004-09-23 Hasso Tepper <hasso at quagga.net>
 226
 227         * *.[c|h]: list -> struct list *, listnode -> struct listnode *.
 228
 229 2004-09-21 LIU Xin <lx at ns.6test.edu.cn>
 230
 231         * isis_dr.c: Update dis_record of adjacencies when isisd becomes DIS.
 232
 233 2004-09-21 Hasso Tepper <hasso at quagga.net>
 234
 235         * isis_lsp.c: Put IPv4 prefixes into reachability TLVs, not
 236           addresses. Make IPv6 work with other prefix lengths than % 8 == 0.
 237
 238 2004-09-20 LIU Xin <lx at ns.6test.edu.cn>
 239
 240         * isis_dr.c, isis_events.c: Remove hello multiplier usage while
 241           scheduling DIS election.
 242         * isis_pdu.c: Don't call isis_event_dis_status_change() whenever
 243           l[1|2]_desig_is is different from hdr.lan_id.
 244
 245 2004-09-19 Hasso Tepper <hasso at quagga.net>
 246
 247         * isis_spf.h: Renamed t_spf_periodic to t_spf as it's not used to
 248           store pointer to periodic SPF thread only.
 249         * isis_spf.c: Cleaned up SPF threads schedule code. IPv4 and IPv6
 250           threads are independant now. Used macros wherever possible.
 251         * isis_lsp.c: Fixed bug in scheduling LSP regeneration.
 252
 253 2004-09-17 LIU Xin <lx at ns.6test.edu.cn>
 254
 255         * isis_circuit.c: According to RFC1142 the first DIS election will be
 256         started 2 * HelloTimer seconds after the initialization.
 257
 258 2004-09-15 Laurent Rabret <laurent.rabret at francetelecom.com>
 259
 260         * isis_pdu.c: Fix error in same subnet comparison. The previous
 261           algorithm only worked when netmask % 8 == 0.
 262         * isisd.c: Show domain and area passwords in configuration.
 263         * iso_checksum.c: Fixed error in the checksum calculation. The previous
 264           algorithm could produce a bad checksum if the 2 complement's vs 1
 265           complement's adaptation was required.
 266         * isis_pdu.c: Authentication in LSPs does not mean authentication in
 267           SNPs.
 268         * isis_tlv.c: Fix errors in password checking.
 269
 270 2004-09-14 Hasso Tepper <hasso at quagga.net>
 271
 272         * isis_circuit.c: Mostly cosmetical changes in isis_circuit_add_addr()
 273           and add calls to isis_event_int_reach_change(). Implement
 274           isis_circuit_del_addr(). Cancel t_run_dr threads is circuit goes
 275           down.
 276         * isis_events.c: Implement isis_event_int_reach_change(). I'm not sure
 277           yet how this stuff should work, but it allows be to start debug
 278           threads which act very weird at the moment.
 279         * isis_tlv.c: Much less verbose by default.
 280         * isis_zebra.c: Added extreme debugging output. Call connected_free()
 281           after isis_circuit_del_addr, not before.
 282         * isisd.conf.sample: Update it a little bit. 10000 seconds hello time
 283           was certainly too much IMHO.
 284
 285 2004-09-14 LIU Xin <lx at ns.6test.edu.cn>
 286
 287         * isis_pdu.c: Update l1_desig_is only if neighbor really is DIS.
 288
 289 2004-09-10 LIU Xin <lx at ns.6test.edu.cn>
 290
 291         * isis_pdu.c: Goto out only if no adjacency exist.
 292         * isis_circuit.c: Don't crash while executing "isis circuit-type"
 293           command if circuit exists, but circuit->area is still NULL.
 294         * isis_lsp.c: Set pointers to thread to NULL before initiating new
 295           thread in lsp_l1_refresh_pseudo(), lsp_l2_refresh_pseudo() and
 296           lsp_tick() functions.
 297
 298 2004-05-19 Laurent Rabret <laurent.rabret at francetelecom.com>
 299
 300         * isis_constants.h: change the ISIS Hello interval from 1 to 10 (cisco's
 301           default value).
 302         * isis_main.c: suppress a bad "#if 0 #endif" block for isis to be
 303           activated on startup.
 304         * isis_tlv.[c|h]: LSP recognition of the ISIS Graceful Restart LSP (not
 305           implemented yet).
 306
 307 2004-05-19 Rivo Nurges <rix at estpak.ee>
 308
 309         * *.c: Removing many useless net/ethernet.h includes and some tiny
 310           fixes to make it compile on NetBSD and OpenBSD.
 311
 312 2004-05-08 Paul Jakma <paul@dishone.st>
 313
 314         * isis_zebra.c: Sync with zclient changes.
 315
 316 2004-02-11 Hasso Tepper <hasso@estpak.ee>
 317   * many *.c files: Replace thread_add_xxx() and thread_cancel() with
 318     THREAD_XXX_ON and THREAD_XXX_OFF macros.
 319
 320 2004-01-27 Hasso Tepper <hasso@estpak.ee>
 321   * isis_circuit.c: Commented out "(no) ip address" commands so it doesn't
 322     confuse vtysh.
 323
 324 2003-12-31 Hasso Tepper <hasso@estpak.ee>
 325   * isis_dr.c: Fix some threads related bugs.
 326
 327 2003-12-23 Hasso Tepper <hasso@estpak.ee>
 328   Some fixes done by me and Cougar <cougar@random.ee>.
 329   * isis_adjacency.c: Two bugfixes by Cougar:
 330     After down state neigbour was deleted but not removed from neighbours list.
 331     Don't show random expire time during neighbour initialisation.
 332   * isis_circuit.c: Don't show interface addresses in config by Cougar.
 333   * isis_constants.h, isis_misc.c: Show other well-known NLPID names as well
 334     by Cougar.
 335   * isisd.c: Two tiny CLI fixes by me.
 336   * isis_lsp.c: Bugfix in lsp_print_detail() by Cougar.
 337     Show IPv4 external and IPv6 TLV's in "show isis database detail" by me.
 338   * isis_misc.c: Net address format fix by Cougar.
 339   * isis_spf.c: Dead loop fix in isis_spf_preload_tent() by Cougar
 340   * isis_zebra.c: Ignore distance when adding route to zebra for now by me.
 341   * isis_tlv.c: Parse external IPv4 TLV's correctly by me.
