isisd/ChangeLog

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