15 0.6.1 --------------------------------------------------------------------
17 Bugfix release for 0.6.0
19 Markus Kittenberger <Markus.Kittenberger@gmx.at>
20 - Major bugfix for the neighbor table when a neighbor gets a new main IP.
21 - add /interface command to txtinfo, allow multiple commands per request
23 Henning Rogge <henning.rogge@fkie.fraunhofer.de>
24 - wait up to four seconds for aquiring the OLSRd lock. This helps to
25 shutdown OLSRd with a script and restart it at once (kill <pid> is
26 asynchrone, and kill -w is not available in busybox)
27 - add md5 has of all source/headers into version string
29 Mitar<mitar@tnode.com>
30 - lot's of small changes for Android. Slowly Android gets a fully
31 supported platform for OLSRd.
33 and a lot more small bugfixes. Read GIT changelog at http://olsr.org/git
34 to see a complete history.
36 0.6.0 --------------------------------------------------------------------
38 Change in version number system. No more -rcX for release candidates and
39 -rX for bugfix releases. In future bugfix releases or updates of plugins
40 will increase the third digit of the version string while feature releases
41 will increase the first and/or the second one.
43 Markus Kittenberger <Markus.Kittenberger@gmx.at>
44 Henning Rogge <henning.rogge@fkie.fraunhofer.de>
45 - added NIIT kernel module support for sending IPv4 traffic over
46 IPv6 mesh networks. See README-Olsr-Extensions for more information.
47 - added SmartGateway support. OLSRd can now automatically build
48 IPIP tunnels towards the gateway to prevent gateway flapping.
49 See README-Olsr-Extensions for more information.
50 - complete rewrite of linux netlink routing code. New code should be
51 more understandable and easier to debug/improve.

86 notified if an OLSR node switch down to remove it from their database.
87 - cleanup of naming conventions for settings src/dst-ips of OLSR-packets
88 for ipv4/6. See example config files.
89 - patch to ignore HNA4 for IPv6 and HNA6 for IPv4
91 Markus Kittenberger <Markus.Kittenberger@gmx.at>
92 - patch series for MID handling cleanup
93 - compiletime switch for txtinfo to always allow localhost access
94 - add "InterfaceDefaults" section to config files to allow setting values
95 which are shared by all interfaces but can be overwritten in specific

310 (all to be found on http://download-master.berlin.freifunk.net/sven-ola/nylon/packages/olsrd/files/)
311 - Replaced "which" with a /bin/sh script snippet
313 PATCHES and CLEANUPS by Bernd Petrovitsch <bernd@firmix.at>
314 - Jens Nachtigall <nachtigall@web.de> suggested (and reminded) to use
315 olsrd.conf.default.lq as the default installed one.
316 It makes much more sense as - to the best of my(bernd's) knowledge - all
317 larger networks uses the LQ extensions. And new customers should better
318 be pushed in that direction.
319 - with the help of Patrick McCarty <mccartyp@gmail.com>, we got olsr to build
321 * OpenBSD'd `sed` is pretty conservative and doesn't understand 's|re|sub|'.
322 So we fall back to the old 's/re/sub/' and quote all '/' and '.' correctly
323 (which was the main reason to use '|').
324 And while I'm at it: Remove the useless $(CCACHE) from the $(CC) for
325 dependency generation and beautify (read: "$(strip)") $(CPPFLAGS).
326 * OpenBSD needs an explicit "#include <sys/types.h>" before
327 "#include <netinet/in.h>".
328 - fixed lib/secure/src/md5.h: This was broken as it had
329 "typedef unsigned long int UINT4;". "unsigned long int" is 8 bytes on x86_64.
330 We are using now the standardized types from <inttypes.h>.
331 - fixed warnings and improved lib/secure/src/md5.c:
332 * we are using memcpy() and memset() instead of the open-coded loops as
335 * added function prototypes for static functions
336 * moved static functions to the top so that their declaration is before
337 their use to allow gcc to inline if only used once.
338 It remains ugly - God knows why there are that so many useless
340 - Some minor and trivial cleanup: Added two functions to calculate the ETX
341 value from a struct tc_edge_entry and a struct link_entry, respectively.
342 And use them everywhere.
343 - added http://meshcube.org/nylon/utils/olsr-topology-view.pl into
344 lib/httpinfo/misc as suggested by Jens Nachtigall <nachtigall@web.de>
345 - Killed "struct olsrd_config *cnf" in src/cfgparser/olsrd_conf.h and replaced
346 it's usage with "olsr_cnf" from src/defs.h.
347 Serious cleanup: olsrd_get_default_cnf() does no longer initialize the global
348 "cnf" variable" but uses a local one which is returned as before. And
349 olsrd_parse_cnf() does no longer return the global variable it is working on.
350 - Merged "struct hna4_entry" and "struct hna6_entry" into
351 "struct local_hna_entry" (as "struct hna_entry" is a different thing)
352 Both have almost the same data (IP address + netmask/prefix) so we use
353 the quite new "struct olsr_ip_prefix" to store it.
354 Also merged the "hna4" and "hna6" pointer in "struct olsr_config" -
355 look at the global "olsr_cnf->ip_version".
356 - added a olsr_ip_prefix_to_string() function
357 - .h file cleanup: def.h does not longer include net_olsr.h because it
359 - more type safety: the macros COPY_IP() and COMP_IP are gone and replaced
360 with "=" or similar "normal" C operations. There are also now the inline
361 functions ip4cmp() and ip4equal() to work on "struct in_addr", ip6cmp()
362 and ip6equal() to work on "struct in6_addr" and ipcmp() and ip6equal()
363 to work on "union olsr_ip_addr".
364 Most (or even more precise: almost all) uses of COPY_IP() and COMP_IP()
365 are in "if (olsr_cnf->ip_version) { ... } else { ... }" anyway to
366 there is no reson to copy an IPv4 address effectively with
367 "memcpy(&dst, &src, 4)" or compare with memcmp(&a, &b, 4)" wher the
368 always "4" is stored in a variable inhibiting compiler optimization.
369 There is also the deprecated function genipcopy() mimicking the old
370 typeless COPY_IP() macro for the last few places where a cleanup is
372 There also lots of old macros left over (commented out of course) until
373 we are confident that everything works. And then I will kill them too.
374 - Fixed the misleading definition of "v4" in "struct olsr_ip_addr" fom
375 "olsr_u32_t" (in network-byteorder!) to "struct in_addr". Lots of
376 temporary variables to call inet_ntoa()/inet_ptoa() vanished .....
377 - We have now ip4_to_string(), ip6_to_string() and olsr_ip_to_string()
378 to print a "struct in_addr", "struct in6_addr" and "union olsr_ip_addr"
379 into a string buffer.
380 - cleanup: olsr_ip_to_string() and similar non-reentrant functions now must
381 get a target buffer. To ease that, there is the "struct ipaddr_str"
382 which is large enough for all of them (read: for an IPv6 address). This
383 also removes the cyclic buffer there.
384 All of these function return a "const char *" which can be directly used
385 for printf(3) and friends.
386 - const'ified more functions
387 - converted the source to UTF-8.
388 - "struct sig_msg" uses an olsr_u8_t for a byte array (and not "char")
389 - force the few inline function to always be inlined.
390 - #ifdef the body of the olsr_print_hna_set() and olsr_print_neighbor_table()
392 - declare "int_addr", "int_netmask" and "int_broadaddr" in "struct interface"
393 as "struct sockaddr_in" since it is that what we actually want there (and
394 it is similar to the IPv6 code).
395 - updated the olsrd.conf.default.lq-fisheye to the Debian-deliverd version
396 after recent discussions olsr-dev@olsr.org
397 - use "inline_avl_comp_ipv4()" in "avl_comp_ipv4()"
398 - clean up the routes on more signals. Basically we want to do this on all
399 signals which terminate the program.
400 - killed a superflous global buffer in src/main.c
401 - made inline functions from avl_walk_{first,last,next,prev} and created
402 "const" versions of it. inline_avl_comp_ipv4() is now also an inline function
404 - created a typedef's for various function pointers - much easier to read.
405 - cleanup: compare tree->comp (adn other pointers)) to NULL (and not 0)
406 - killed superflous "return"s at the end of void functions
407 - const'ified more parameters in many more functions in the .h and
409 - init-functions with constant or ignored return values are "void"
410 - created a typedef fro the callback in "struct export_route_entry"
412 - moved the initialization of the {add,chg,del}_kernel_list variables
413 into process_routes.c. So they are now "static" there.
414 - olsr_export_{add,del}_route{,6} are now static in process_routes.c
415 since they are not used elsewhere.
416 - olsr_addroute_add_function() and olsr_deldroute_add_function() were
417 almost identical - made one function out of it.
418 Same for olsr_addroute_del_function() and olsr_deldroute_del_function().
419 - fixed the sort order in avl_comp_ipv4_prefix(): We compare now the IPv4
420 values in host byte order (and not network byte order). So the route
421 list in the e.g. httpinfo plugin is now nicely sorted.
422 - fixed and improved the `gcc-warnings` script:
423 * support older gcc's (as on Debian/Sarge) as they have slightly different
425 * removed superflous lines
426 * replaced the call of `sed` with shell built-in features fixing syntax
427 errors on Debian/Sarge
428 * set all locale-relevant variables to "C" (just to be sure)
429 - consolidated ip{4,6,}{cmp,equal}: all are nwo inline functions using only
430 the minimal necessary operations. Thanks to Hannes Gredler
431 <hannes@gedler.at> and Sven-Ola Tuecke <mail2news@commando.de> for pointing
432 that out and suggesting the `inline`, respectively.
433 use ip{4,}cmp in lq_avl.[ch] to resue the code. inline_avl_comp_ipv4
434 is superflous now (and replaced by ip4cmp) and use the global MIN and MAX
435 macro instead of AVLMIN and AVLMAX
436 - killed netmasks from the IPv4 part of the code and use the prefixlen there
437 (similar to thte IPv6 part). Manymore details on
438 http://lists.olsr.org/pipermail/olsr-dev/2007-November/001464.html
439 - removed the superflous "open_ipc" field from the "struct olsrd_config" as
440 it contains only the equivalent of "olsr_cnf->debug_level > 1".
441 - inspired by Sven-Ola Tuecke: avoid a bash'ism (i.e. "OPTS="${OPTS//$opt}") in
442 gcc-warnings and ld-warnings. But we do not replace it with `sed` (since it
443 costs a fork(2) and an exec(3)) but also with shell code which doesn't use
444 any external program.
445 - added configuration file support for "flat fib metrics".
447 0.5.4 ---------------------------------------------------------------------
449 QUAGGA by Immo 'FaUl' Wehrenberg <immo.olsr@do.bundessicherheitsministerium.de>
450 - updated to svn version 33
452 BMF PLUGIN by Erik Tromp <erik_tromp@hotmail.com>
454 - updated to latest plugin interfaces changes and killed warnings (by Bernd
455 Petrovitsch <bernd@firmix.at>)
457 PATCH by Hannes Gredler <hannes@gredler.at> which rewrites the route handling.
461 - get rid of separate routing tables for HNA and per-node routes, everything is
462 now unified in an AVL routing tree (&routingtree)
464 - introduce walking macros (OLSR_FOR_ALL_RT_ENTRIES()) that hide the internal
465 structure of the RIB for making life of the plugin authors easier.
467 - get rid of different SPF implementations for LQ and non-LQ code paths. a
468 non-LQ edge is simply substituted with a cost of 1.0
470 - get rid of host masks - a new data type olsr_prefix is introduced which is
471 basically an ip address plus a prefix length.
473 do not install the metric in the kernel FIB - for the kernel its pointless
474 if the route gets installed with a metric of N or M.
476 we do not need to update the kernel FIB if we have hop count only changes
477 (for example if there is a reroute action further downstream)
479 the only things which triggers a kernel FIB route update is a next hop
480 change (a next hop is neighboring gateway router plus an interface).
482 all OLSR routes are installed with a metric of 2
484 - separate between rt_entry and rt_path - the former is a route installed in the
485 kernel with an next hop. the latter is a candidate for best path selection
486 after SPF calculation has been done. in the rt_entry we keep a pointer to the
487 best_path and also to the next hop that was installed in the kernel FIB.
489 we always keep all originator of a route, if a route originator goes away we
490 can easy recompute the best path for the route.
492 the next hop in the rt_entry gets only updated upon a successful route_add
493 call - that way we always remember what next hop to delete.
495 stray routes should be history now.
497 - tweak the linked list toolkit to operate on circular lists.
499 - get rid of malloc calls for building the kernel update list. the list node is
500 now embedded in the rt_entry.
502 - introduce three queues (add/chg/del) for kernel updates.
504 - for neighbor route dependency tracking the neighbor routes are queued first or
505 last (depending on which queue you work on)
507 - rework all the plugins which directly manipulate rt entries.
509 - rework the plugins that read from the routing table (most notably nameserver,
510 httpinfo and quagga plugin)
512 - lots of comments that explains the intentions and purpose of this code-piece.
514 non RT related stuff:
515 - use a list rather than a tree for storing the post-SPF results, which further
516 improves the raw-SPF runtime.
518 - add display of SPF runtime (masked behind #ifdef SPF_PROFILING)
520 - http://gredler.at/download/olsrd/neighbor_routes3.diff: This updates the own
521 IP address (read: the main address) after changes (e.g. on
522 `ifup wlan0; sleep 1; ifdown wlan0`) and kills the
523 olsr_fill_routing_table_with_neighbors() function.
525 And Sven-Ola Tuecke <mail2news@commando.de> fixed an instability issue on interface
526 up/down operations (see 102-olsrd-rt-refactoring-fixes.patch below) and a missing
529 PATCH by Hannes Gredler <hannes@gredler.at> which "consolidates
530 the link-state database and the spf-calculation in order
531 to calculate routes more efficiently".
534 - use the link-state (tc) database for SPF calculations rather than
535 replicating the notion of vertices and edges for a SPF run.
536 this heavily reduces malloc() calls and shrinks the total CPU
537 load of the route calculation path between 60%-80%.
540 PATCHES by Sven-Ola Tuecke <mail2news@commando.de> to be found on from
541 http://download-master.berlin.freifunk.net/sven-ola/nylon/packages/olsrd/files/
542 - 102-olsrd-rt-refactoring-fixes.patch
543 Because you changed a lot of basics: It's time to handle a general
544 flaw in the routing system. Plase take a look at chk_if_changed(). This
545 will free() any "struct interface" pointer without warning at any time.
546 This is why it's possile to SEGV olsrd with a simple "ifdown xxx".
547 The patch replaces the (maybe) invalid pointer with an index reference
548 "iif_index". You can always ask the OS for a name. Please note, that I do
549 not have a working BSD toolchain, so I've placed an #error in the IPv6
550 BSD-part where the author/porter has started to hack something funny.
552 - 110-olsrd-double-wlancard-neigh-hack.patch:
553 This is a hack for Nodes having to wifi cards with the same channel,
554 bssid, IP-Range etc. If two nodes can see each other by means of two
555 possible links (here: two wifi cards with equal config), a bug is triggered
556 with the Neigh-is-SYM detections. This small little hack prevents this.
558 - 112-olsrd-nameservice-fixemptyname.patch:
559 This is an addon to my lat/lon stuff which will prevent olsrd from
560 running (oops?) if no hostname is given and the nameservice plugin
563 - 113-olsrd-dyngwplain-pluginvers5.patch:
564 This updates the dyngwplain plugin to the new Plugin Iface
566 - 140-olsrd-arprefreshed.patch:
567 This is a new one. Opens a packet socket and listen to UDP(698), extract
568 the sender MAC and refreshes the ARP cache whith that. Should speedup
569 especially in cases, if you initially try to use a longer routing path which
570 normally triggers a "ARP-Lookup-Chain".
571 - 106-olsrd-nameserviceparams.patch:
572 This patch converts more plugins to the new interface version.
573 - 104-olsrd-policy-routing.patch
574 Reworked this one to discard GPL helper functions. Also checked IPv6 and
575 re-included the IPC hookup. The patch adds a "RtTable [number]" for
576 /etc/olsrd.conf which is simply the Linux
577 policy routing table to use. Defaults to 254 (== main).
578 This patch was modified/clenaed up by <bernd@firmix.at> to use "#if"
579 instead of "#ifdef" as it's more robust against typos.
580 - 110-olsrd-fixpacketprint.patch, 112-olsrd-nameservice-fixemptyname.patch,
581 113-olsrd-txtinfo-fixhttpget.patch, 114-olsrd-timeoutlimit.patch,
582 115-olsrd-nameserviceparamfix.patch and
583 116-olsrd-fix-pluginparam-addons.patch fixing the compilation warning
584 on 64bit and lots of other improvements.
585 - "Save the fish" patch: Avoid forwarding of packets with too low TTL. This
586 kills lots of packet forwarding storms.
587 NB: The oneliner was applied by hand by BP and formatted to look (in BPs O)
590 PATCH by Arnd Hannemann <hannemann@i4.informatik.rwth-aachen.de>
591 olsr_makefile_make_use_of_exename.patch
592 - This patch makes sure that the EXENAME variable of Makefile.inc is used
595 PATCHES by John Hay <jhay@meraka.org.za>
596 - update to new FreeBSD WLAN API
597 - do not require /bin/bash, use /bin/sh
598 - Fixed alignment so that olsrd runs on FreeBSD/arm
599 - allow more interface in an IPv6 subnet on FreeBSD
600 - use PREFIX and DESTDIR as all the other Makefile.$OS also for FreeBSD
601 - make txtinfo plugin work with IPv6
603 PATCH by Andreas Jacobs <jacobs@i4.informatik.rwth-aachen.de>
604 - fix the loss link quality calculation for "windows size % 4 != 0"
606 PATCH by Acinonyx <acinonyxs@yahoo.gr>
607 - Bug fix: include $(TOPDIR)/Makefile.inc at the begin in the Quagga plugin
609 PATCH by David Cornejo <dcornejo@gmail.com>
610 - fixed an "+=" of an uninitialized variable (detected with/by the
613 BUG reported by Aaron Kaplan <aaron@lo-res.org>
614 - BSD-xargs doesn't know "-r".
616 PATCHES and CLEANUPS by Bernd Petrovitsch <bernd@firmix.at>
617 - Made a function from the ME_TO_DOUBLE() macro (in src/mantissa.h).
618 This saves code throughout the code even on i386 and will even more
619 on architectures without floating point units and "-msoft-float".
620 - And the mathemathics in src/mantissa.h is reformulated to minimize
621 floating point operations to save CPU power - especially on embedded
623 - I rewrote the half of src/lq_packet.[ch] which deals with incoming
624 packets. This was triggered with performance output of gcc produced
625 by Sven-Ola Tuecke at CCCamp07.
626 This kills *lots* of (more than) superflous malloc()s and the same
627 number of (free()s). And it also kills some code and copying around of
629 - Make it compile without warning with flex-2.5.33 (to be found on Fedora 7
630 and Gentoo in Sep-2007) again.
632 - converted the dyn_gw plugin to plugin interface version 5 (which leaves
633 the quagga plugion as the last with the old one).
634 - paving the way to activate -Wshadow, much more to do
635 - const-ify parameters here and there
636 - use NULL for pointers (and not "0")
637 - Killed "extern" declarations in (not generated) .c files
639 - Based on a patch by Gianni Costanzi <gianni.costanzi@gmail.com> (so credits
640 and thanks have to go there):
641 added OS_CFLAG_PTHREAD Makefile variable since gcc (on Linux) requests this
644 - I added definitions to all OS-specific Makefile.$OS with the value similar
645 to the value in OS_LIB_PTHREAD (either empty or "-pthread").
646 - The variable is added to CPPFLAGS (and not CFLAGS) since CPPFLAGS is used
647 for all cpp and gcc calls (and gcc's man page indicates that it sets
648 variables for both of them).
650 0.5.3 ---------------------------------------------------------------------
653 Ignacio GarcÃa Pérez <iggarpe@terra.es> found a serious bug in the dot-draw
654 plugin and identified it's source.
657 The bmf plugin wanted to kill a not-started thread and this causes a segmentation
658 violation. This happens if the old plugin interface support is not compiled in
659 and one uses - or more asccurate: wants to use - the bmf plugin which uses that
660 ATM. Thanks to Cedric Krier <ced@ced.homedns.org> for reporting this.
663 The dependencies (*.d files) are now properly generated and used. And they also
664 dependen on the Makefile in the current directory and the Makefile.inc so that
665 changes there also lead to new compilation.
666 Remember: We support "ccache" so install it to save lot of meaningless recompiles
667 if nothing (as seen by the real C compiler, i.e. after the C preprocessor) has
671 Linux/IA64 and Linux/HPPA also need "-fPIC".
674 - olsr_switch does no longer generate warnings
675 - olsr_switch is also built with "build_all" and cleaned with "uberclean"
676 - More "const" all over the place.
677 - More "static" for local functions and variables.
678 - Killed an unnecessary "static" variable.
680 0.5.2 ---------------------------------------------------------------------
683 Sven-Ola Tuecke found a serious bug of the class "show stopper" and sent a patch.
686 Plugins handle parameters quite individually (case-sensitive vs case-insensitive,
687 different parsing functions for the same values, etc.). Plugin Interface version 5
688 now exports a table of { parameter-name, parsing-function, addr-of-storage } and
689 it's size. Common functions should be shared.
691 0.5.1 ---------------------------------------------------------------------
694 Upgrade to olsr-bmf 1.5 from Erik Tromp <erik_tromp@hotmail.com>
696 latitude/longitude support is now in the nameservice plugin done by
697 Sven-Ola Tuecke <mail2news@commando.de>
699 added the spf refactoring patch from Hannes Gredler <hannes@gredler.at> which
700 saves a noteworthy amount of CPU time. To quote him:
702 1. use of an AVL tree as a min-heap implementation
704 as a means for efficient sorting.
705 (the etx metric is used as the key in the candidate tree)
707 2. next-hop propagation
709 rather than tracking the previous node in olsr_relax()
710 i have changed that model and pre-populate all one-hop neighbors
711 with their own IP adress as 'next-hop' and pull that
712 pointer up once new paths are explored.
714 as a result no walker for counting hops and extracting next-hops
715 is required - it turns out at this is slighly more efficient
716 than the existing behaviour (even with the cache applied).
720 * moved a only locally needed hack from "union olsr_ip_addr" into the only place
721 where it is needed in hashing.c
723 0.5.0 ---------------------------------------------------------------------
725 APPLIED PATCHES FROM FREIFUNK-FIRMWARE
726 libsmake, dyngwplain, nameservices+services, tzxtinfo, quagga, quagga-routehandler,
727 optimize, fixes from Eric Tromp and Sven-Ola Tuecke, CPU-optimize, secure key, HNA-IP
730 removed hardcoded limit on the number of interfaces (at least in the Unix part)
731 made Makefile targets much more consistent
734 put Bmf-1.3 plugin into it
738 Patch from John Hay applied.
742 0.4.10 --------------------------------------------------------------------
744 OLSR NETWORK SIMULATOR
746 An application called olsr_switch(sorry for the nameclash with the win32
747 GUI) has been added. If olsrd is ran using the -hint option it can now
748 connect to olsr_switch and be part of a virtual network. This means
749 that multiple instances can be ran at the same host! The olsr_switch
750 application allows the user to define link variables on all viritual
751 links in the network, creating all possible topologies. Read more in
754 EXPERIMENTAL FISH EYE ALGORITHM
756 An experimental algorithm for TTL settings on TC messages has
757 been added. Read more in the corresponding README file.
761 olsrd now also compiles on OpenBSD systems. Thanks a lot to Holger
762 Mauermann for the patches!
766 Bruno has rewritten the make system. OS detection is now done
767 automagically and the general design is much improved.
769 IP ADDRESS VALIDATION
771 Olsrd now maintains a set of IP addresses that is considered
772 invalid. Checks against this set is done on all received
773 OLSR packets announced originator addresses. The dataset can
774 be updated dynamically.
778 Updated interface version to 3 and added more noticeable warning
779 for version missmatch.
783 The dependency on the math lib came from the use of pow(3) in the
784 mantissa/exponent calculation. The calls to pow in this long forgotten
785 code, was very unnessecarry. The pow calls are replaced with bitwise
786 shifts and -lm is no longer needed.
788 ICMP REDIRECTS ON LINUX
790 On Linux systems "0" is now also written to the all/send_redirects
791 procfile and not only the pr. interface ones. Hopefully this resolves
792 problems reported with systems still sending ICMP redirects.
796 - Fixed init of IPv6 addrtype variable. It used to be uninitialized,
797 causing it to default to site-local and have some weird side-effects.
798 - Fixed crash when changing IPv6 address at run-time
799 - Fixed a bug that prevented setting willingness 0 in the configfile
800 - Fixed bad handling of missing command line arguments
801 - Did various updates to prevent assertion when a neighbor
802 has changed IP and sends HELLO before its olsrd precess has detected
804 - Fixed return value check on times(2) calls in the scheduler
805 - Fixed bug(s) that could cause crash when an interface was brought
806 down while olsrd was running.
807 - Removed the silent (read: unchecked) hard limit of 16 interfaces.
808 - Compiles now cleanly on 64bit (e.g. x86_64).
810 0.4.9 ---------------------------------------------------------------------
814 The MID database is now also indexed by alias addresses. this makes
815 look-ups of main addresses based on alias addresses _much_ faster.
816 The mid_lookup_main_addr function alone has gone from >30% of the
817 total CPU time used by olsrd to <1%.
818 PLUGIN DEVELOPERS: datatypes for MID entries has been changed.
820 Routing table calculation in the LQ case now uses balanced binary
821 trees instead of linked lists, which makes look-ups much faster.
823 The debug output function olsr_printf() is not used by olsrd
824 internals any more. Instead the macro OLSR_PRINTF is to be used.
825 This macro does debug level testing _before_ doing any function
826 calls(both printf itself and parameters to printf). This is a much
827 more optimized way of doing debug output. In addition olsrd can
828 be built without any debug output code if doing 'make NODEBUG=1'.
832 Validity times for dataset entries are now set using the clock_t type
833 (used to be struct timeval). This data is now fetched from the times(2)
834 function instead of gettimeofday(2). This prevents possible problems
835 if the system time is changed.
836 PLUGIN DEVELOPERS: Note that datatypes for close to all dataset entries
837 (link, neighbor, mid, hna, tc etc.) has been changed!!
841 Multiple interfaces can now use the same interface configuration block.
843 Interface "if0" "if1" "if2"
848 Interface configurations now also support the "Weight" directive. When
849 olsrd finds multiple links to a neighbor it will choose the link
850 going via the interface with the lowest weight. Olsrd normally
851 sets this weight dynamically based on interface characteristics,
852 but if the user wishes to set a fixed weight in a interface(or
853 a group of interfaces), this directive is now available.
855 Moreover, interface configurations now support the "LinkQualityMult"
856 directive. It takes an IP address and a multiplier as arguments.
864 LinkQualityMult 192.168.0.1 0.7
865 LinkQualityMult default 0.5
870 The idea is to make certain links via the configured interface
871 artificially worse or better than they really are. The first parameter
872 specifies the IP address of a neighbour interface. The second
873 parameter is the multiplier to be applied to the link to the specified
876 After we have derived the link quality from the packet loss among the
877 packets received from the specified neighbour interface, we multiply
878 the link quality by the given multiplier. So, the multiplier changes
879 the LQ value that we use when determining the ETX, which is 1 / (LQ *
882 If "default" is given as the IP address then the multiplier applies to
883 all links via the configured interface. Note, however, that olsrd only
884 assigns one multiplier to each link. It does so in the following way.
886 * If there is a "LinkQualityMult" line that matches the IP address of
887 the link's neighbour interface, then use the multiplier in this
890 * If there isn't any matching line, then look for a "default" line. If
891 there is a "default" line, then use the multiplier in this "default"
894 * Otherwise use 1.0, i.e. do not modify the LQ value at all.
896 Hence, a line with an IP address has priority over a "default" line.
898 In the above example, the LQ value of the link between the local
899 interface if0 and the neighbour interface 192.168.0.1 would be
900 multiplied by 0.7. All other links between the local interface if0 and
901 a neighbour interface would be multiplied by 0.5.
905 The socket option IPV6_V6ONLY is now set on IPv6 sockets in linux.
906 This means that olsrd will no longer receive IPv4 traffic when
907 running in IPv6 mode.
908 This should enable users to actually run one olsrd instance using
909 IPv6 and one using IPv4 at the same time :)
913 The httpinfo, dyn_gw and dot_draw plugins now all include olsrd
914 headerfiles directly. A plugin should define OLSR_PLUGIN before
915 including olsrd headers. Doing things this way removed the
916 redundant datatype definitions that has so often caused trouble
917 when things has been updated in olsrd.
921 olsrd now also compiles on NetBSD systems. Use 'make OS=nbsd' to
922 build. This port is not very well tested and feedback is greatly
925 EXPERIMENTAL MULTI-INTERFACE CODE FOR FREEBSD
927 Experimental code using libnet can be compiled in allowing multiple
928 interfaces to be used in FreeBSD. You enable this by compiling using
929 OS=fbsd-ll. You must have libnet-devel installed for this to work
930 (/usr/ports/net/libnet-devel).
934 - WLAN devices are now detected in FreeBSD
935 - First specified interfaces IP is used as main address.
936 - Broadcastflag is not checked on interface if fixed broadcast is
938 - Removed Linux link layer code as this was not really in use.
939 - Added -nofork command line option
943 - Link sensing now works according to announced vtime from
944 neighbors. Previously links going symmetric->asymmetric
945 were not necessarily detected until the holding time expired.
946 - A bug in route addition/removal that could lead to routes
947 using GWs being added before the actual route to the GW
948 was set up, has been fixed.
949 - A bug in the interface selection in route calculation has been
950 fixed. New routes are no longer added prior to deleting old ones,
951 since this caused trouble.
952 - A bug in the IPv6 multicast address configuration has been fixed.
953 This caused olsrd not to work with global IPv6 addresses.
954 - A bug in the IPv6 prefix-from IPaddr function has been fixed. This
955 bug caused HNA prefixes to always be calculated to 0.
956 - If a 2-hop neighbor is also a 1-hop neighbor, a bug made olsrd
957 prefer a bad direct link to a better link via an MPR.
958 - If a link or interface lookup failed, olsrd crashed.
959 - Fixed a crash in the LQ packet generation code based on a
960 signed/unsigned integer comparison.
963 0.4.8 ---------------------------------------------------------------------
967 Olsrd is now distributed under a BSD style license. We believe olsrd will
968 be better off using this license as it opens up for commercial players
969 to use olsrd freely in their products. In the end this will lead to
970 this kind of users doing serious testing and bug fixing of olsrd.
972 ETX-LIKE LINK QUALITY DETECTION
974 We can now determine the packet loss on a link by looking at the serial
975 numbers of the OLSR messages received from a neighbor. This tells us how
976 many packets get through from our neighbor to us. We use a new extended
977 kind of HELLO messages (LQ_HELLO messages, LQ = link quality) to broadcast
978 the link quality that we have determined on our end of the link to our
979 neighbors. So do our neighbors, and we as well as they end up with an
980 idea of how good the link is in both directions. From the LQ_HELLOs we
981 also learn the link quality between our neighbors and our two-hop neigh-
982 bors. In this way we can select those neighbors as MPRs that have the
983 best links to our two-hop neighbors. To distribute the link quality
984 throughout the network, we use a new extended version of TC messages
985 (LQ_TC messages). They contain the qualities at both ends of each of our
986 links. Nodes can then run Dijkstra's algorithm to find a path between
987 themselves and other nodes that minimizes the packet loss.
989 If the newly introduced "LinkQualityLevel" is set to zero in the
990 configuration file, link quality is not used and the daemon behaves as
991 before, i.e. as specified by the OLSR RFC. If this parameter is set
992 to 1, LQ_HELLOs and LQ_TCs are used instead of HELLOs and TCs, link
993 quality is measured and MPRs are selected based on the link qualities.
994 If this parameter is set to 2, the routing table is additionally
995 calculated based on the link qualities.
997 Setting "LinkQualityLevel" to a non-zero value BREAKS COMPATIBILITY. You
998 will then not be able to participate in RFC-conformant OLSR networks
999 any longer. This is because we use LQ_HELLOs and LQ_TCs instead of HELLOs
1000 and TCs in this case.
1002 It's best practice to set "LinkQualityLevel" to the same value on all
1005 When determining the quality of a link olsrd only considers a given
1006 number of most recent OLSR packets received from its neighbors. By
1007 default, olsrd looks at the 10 most recent OLSR packets. This can be
1008 changed via the "LinkQualityWinSize" configuration option. Values
1009 between 3 and 128 are legal.
1011 NEW CONFIGFILE PARSER/FORMAT/SCHEME
1013 A whole new config file syntax and parser is introduced with this
1014 release. The parser is generated using flex and bison and it is
1015 designed to be very modular. The parser can be compiled as either
1016 a standalone binary, a shared library or as part of olsrd. This way
1017 other applications can parse and generate olsrd configuration files
1018 only by linking to the dynamic library.
1019 In the new configfile options can be set pr. interface, plugin
1020 parameters can be set, more IPC options can be set...and more.
1021 The syntax is documented in the olsrd.conf(5) manual page found
1022 in the files/ directory.
1023 Olsrd internals now uses a single struct, as returned by the config
1024 parser, for all configuration in runtime. this means that updating
1025 values in this struct will dynamically update olsrd operation. It
1026 also means that all configuration is now kept in one place instead
1027 of spread all across the place.
1029 FREEBSD AND MAC OSX PORT
1031 This version offers an initial port of olsrd to FreeBSD and Mac OS
1032 X. Like the Windows port it currently does not support IPv6. As this
1033 is a very first try at supporting FreeBSD and Mac OS X, this port is
1034 probably not as reliable as the Linux version. We'd greatly appreciate
1035 feedback and bug reports. To compile you need GNU make. Then simply
1036 run "gmake OS=fbsd" to build the executable.
1040 The makefiles used to build olsrd have been rewritten and now includes
1041 dependency file generation using makedep.
1045 Tables are now only printed if changes occur, so there are no longer
1046 any periodical output when using a debuglevel >0. A "heartbeat" is
1047 now printed to STDOUT(if it is a terminal) in the form of a rotating
1048 line to show that olsrd is actually operating.
1049 Adding "ClearScreen yes" to the configuration file clears the screen
1050 each time before the debug output shows updated information. This
1051 makes the debug output easier to read in many cases. "ClearScreen no"
1052 is the default, if no "ClearScreen" directive is given in the
1057 There are some changes in the plugin interface. It is now at
1058 version 2. Plugin specific parameters from the configfile
1059 using the PlParam option, will now be passed on to plugins.
1060 To receive such parameters a plugin must implement a function:
1062 register_olsr_param(char *key, char *value)
1063 to which parameter pairs will be passed.
1067 Olsrd no longer uses any thread library on its operation. Everything
1068 now happens in the main thread allowing for use of olsrd on platforms
1069 with no thread library.
1071 ACPI SUPPORT IN WILLINGNESS CALCULATION(LINUX)
1073 The willingness calculation for Linux, now also supports the more
1074 modern ACPI proc interface in addition to APM. This is not well
1075 tested and feedback is appreciated!
1079 Various options regarding IPC connections can now be set in the
1080 configfile. The options are max connections, allowed unicast
1081 hosts and allowed net-ranges.
1085 Much of the message generation and net output code is rewritten.
1086 Sending of partial messages should now work 100%. Also TC, MID
1087 and HNA messages are now cached for a random amount of time
1088 before transmitted - this often leads to the situation where these
1089 messages are sent together with an HELLO message, which is highly
1090 desirable since it saves network resources.
1091 PLUGIN DEVELOPERS must note that the buffers and size variables
1092 used in net output is no longer directly accessible!
1094 NET OUTPUT CODE REWRITTEN
1096 Every interface now has one outputbuffer registered. This allows
1097 messages to be "cached" as explained above, so that multiple
1098 messages are stacked together.
1099 Also the outputbuffer and size are no longer accessible directly,
1100 an API is available to plugins(and olsr code).
1102 OS DEPENDENT NETWORK INTERFACE
1104 The OS dependent network functions are now defined in net_os.h
1105 instead of being mixed up with internal network functions
1110 A bug that caused the announced ANSN sequence number to never stop
1111 being increased when a change in the MPR selector set was detected
1112 has been fixed. Another TC related bug that caused timed out TC
1113 entries not to be deleted from the routing table in certain cases
1114 has also been fixed. These bugs could cause unstable routes.
1115 A bug that in many cases caused the wrong routes to be deleted
1116 when using IPv6 has been fixed.
1119 0.4.7 ---------------------------------------------------------------------
1121 NATIVE WINDOWS GUI AND INSTALLER
1123 We now have a native Windows GUI. The GTK+ version is no longer
1124 supported on Windows. The new native GUI is pretty compact as it does
1125 not require the GTK+ runtime DLLs. In addition to monitoring olsrds
1126 state the GUI offers an easy way for novice users to configure
1127 olsrd. It's pretty self-explanatory. Have a look at README-WIN32.txt
1128 for details. The Windows version now also comes with an installer
1129 based on the freely available Nullsoft Scriptable Install System
1130 (NSIS). Looks like the Windows port is becoming more and more
1133 WIRELESS INTERFACE DETECTION ON WINDOWS
1135 Like the Linux version the Windows port is now able to tell WLAN
1136 interfaces from wired interfaces. We can now, for example, set
1137 different HELLO intervals for WLAN interfaces and wired interfaces,
1142 The order of updates of calculated routes is swapped. Now new routes
1143 are added prior to deleting old ones. This could fix issues where
1144 in some very very few cases one could experiment loss of routes.
1148 There were quite some bugs in IPv6 operation in 0.4.6. These are
1149 the bugs that were fixed:
1150 - HNA message parsing did not work.
1151 - Some IPv6 addresses were printed as IPv4 addresses in the
1153 - The '-dispin' option now works again.
1154 - A filedescriptor leak in the IPv6 interface detection caused
1158 0.4.6 ---------------------------------------------------------------------
1162 Read the README-WIN32.txt file!
1164 DYNAMIC NETWORK INTERFACE UPDATES
1166 Network interfaces can now be updated and removed/added at
1167 runtime. Olsrd will check all interfaces specified in the config
1168 file or on the command-line, every 5 seconds. If updates
1169 occur, olsrd will register this and update the necessary data.
1170 If interfaces are removed or added, olsrd will detect this
1171 and configure the interfaces. If an interface is removed
1172 olsrd will continue to check the interface, so if say, a PCMCIA
1173 card is removed and later on reinserted(and given the same name),
1174 olsrd will detect this and start running on it again.
1176 Note that olsrd will now run even if no interfaces are detected.
1178 ROUTE CALCULATION UPDATE
1180 All 1 hop neighbor addresses that are not directly reachable trough
1181 a symmetric link in the link set will now be added with a GW in the
1182 routing table. this GW will be an interface address from a registered
1183 symmetric link to the neighbor.
1187 Alias addresses are now registered in the link set processing
1188 if available. This is not to pretty(since the vtime has to
1189 be a mere guess) but it gives faster initial route updates.
1190 If a HELLO is received(at initial registration) from an IP
1191 that is not the same as the one set as main address in the
1192 received HELLO header, then the IP from which the HELLO was
1193 received will be registered as an alias of the main address
1194 set in the HELLO header. The default vtime is set to 15 secs.
1198 All OS dependent interface configuration code is now located in
1199 OS/ifnet.c(that would be linux/ifnet.c if using GNU/Linux).
1200 The functions are available trough the headerfile src/ifnet.h
1204 - Some timer issues fixed
1205 - Got rid of the global socket descriptors
1206 - Updated indexing of network interfaces
1207 - Introduced a global socket to use for ioctl calls(ioctl_s)
1208 - Removed upper limit for interfaces to use
1209 - Point-to-point interfaces are now allowed
1210 - The main select(2) loop now uses a timeout
1211 - A small bugfix in the select fd-set update code
1212 - Some bugfixes in the configuration file parsing
1213 - stdout/stderr are now set to not be buffered
1214 - A bugfix in the MID generation regarding seq. numbering
1218 A new set of functions that are called whenever a change in the
1219 interface configuration(update, addition, removal) is made is
1221 These functions are added and removed very much like the ptf
1222 functions. Available trough the functions add_ifchgf and del_ifchgf.
1224 OBS OBS OBS!!! PLUGIN DEVELOPERS READ THIS!!!!
1226 The interface struct(declared in interfaces.h) has changed.
1227 Plugin developers must update plugins that uses the interface
1230 The headerfile olsr_plugin_io.h which contains the plugin interface
1231 commands now contains a revision list where all changes are
1235 0.4.5 ---------------------------------------------------------------------
1239 A plugin that generates and checks message signatures is added.
1242 PLUGIN: TOPOLOGY GRAPH
1244 A plugin that generates output of the topology in the dot format
1245 is added. See lib/dot_draw
1249 Some optimizations done that should cause fewer route recalculations.
1253 Some bugs reported by Takafumi Tanaka fixed.
1255 RESTORATION OF NETWORK SETTINGS
1257 Network settings like disabling of ICMP redirects and spoof filter, are
1258 now restored at exit by olsrd.
1262 Nodes would in certain scenarios retransmit messages originating for
1263 themselves. This was a RFC incompliance. Reported by Ingmar Baumgart.
1267 No longer setting the HELLO interval of non-wlan interfaces as a multiplier
1268 of the wlan interval. The interval is set seperatly now.
1269 Due to this there are some updates in the configfile imperatives.
1273 Some new macros introduced for table insertion and removal and IP
1274 copying and comparison.
1278 IPv6 bugfixes in the GUI.
1281 0.4.4 ---------------------------------------------------------------------
1285 Routes are no longer added via neighbors declaring a willingness
1288 LINK SENSING AND ROUTE CALCULATION
1290 Link sensing and route calculation has been updated to handle
1291 multiple links between hosts in a sane way.
1295 IP spoof filtering is disabled on the interfaces which olsrd runs.
1296 These settings are not restored!
1300 ICMP redirect message generation is disabled on the interfaces
1302 These settings are not restored!
1304 CONFIGFILE OPTIONS FOR MID AND HNA ADDED
1306 Options to set the MID and HNA emission intervals and
1307 validity time in the configfile added.
1311 Option to set what IPv6 address type(scope) to use in the
1312 configfile added. It can be set to either global or site-local.
1316 Options to set site-local and global multicast addresses
1317 in the configfile added.
1319 EMISSION INTERVAL FUNCTION
1321 Functions to set emission intervals at runtime added.
1323 LINK LAYER NOTIFICATIONS
1325 If started with the -llinfo switch olsrd will collect and display
1326 link-layer information on neighbors. This is no longer limited to
1327 one interface. But no action is taken based on this info - and
1328 there is a upper limit of 8 neighbors from which this info can
1329 be collected pr. interface. This limitation is inherited from the
1330 WLAN drivers and is not something imposed by the olsrd code!
1332 IPv6 HNA MESSAGE FORMAT
1334 IPv6 HNA messages now contains 128-bit netmask instead of prefix.
1338 Added "packet transform functions" which allow plugins to alter all
1339 outgoing OLSR traffic.
1343 Moved most headers out of OS dependent directories. The tunneling
1344 and link-layer notification interface is not yet separated from
1345 the /linux directory.
1349 A manpage(olsrd(8)) describing olsrd has been created. It is installed
1350 when using 'make install'.
1353 0.4.3 ---------------------------------------------------------------------
1357 Olsrd now supports runtime-loadable plugins! A couple of example plugins
1358 are located in the lib/ directory. Read the README files in the various
1359 plugin directories for more info. A directive to load plugins have been
1360 added to the configfile as well.
1361 Documentation of the plugin interface can be fount at http://www.olsr.org.
1363 The plugin interface is designed to be extendable. But it should _always_
1364 be backwards compatible with the interface used in this release!
1366 LINK-LAYER NOTIFICATION
1368 Some preliminary link-layer notification code has been added. Link quality
1369 can be written to stdout if olsrd is started with the -llinfo switch.
1370 No action is currently taken based on this info. And info will only
1371 be retrieved from the interface named "eth1".
1372 This code is not usable for users as of yet!
1376 Neighbors with willingness set to WILL_ALWAYS is now always added. The
1377 MPR selection is optimized as described in RFC3626 section 8.3.1
1382 There was a couple of bugs in the MPR selection code. All fixed.
1386 Users could not run olsrd on multiple interfaces using the Linux 2.6 kernel
1387 series. This is now fixed.
1391 One small bug in link hysteresis initialization and one in HNA route
1394 MESSAGE-SEQUENCENUMBER INCOMPLIANCE
1396 Message-seqnos was implemented on a pr. messagetype and pr. interface
1397 basis. This is not RFC3626 compliant and has been updates. All messages
1398 and interfaces now uses a global seuencenumber.
1400 RANDOM SEQUENCENUMBERS
1402 Sequencenumbers are now initialized using a random value.
1406 Fixes for running olsrd in daemon mode(debug 0).
1410 Optimizations based on profiling implemented.
1414 Message size is checked for every message before passing it to the
1415 appropriate message parsing function. If the size is bigger than the
1416 remaining size of the olsr packet then the message is discarded.
1420 Some minor modifications done to the gui.
1424 Lots of changes in handling of registration and unregistration of
1425 scheduler, socketparser, parser and local hna set.
1426 Some restructuring and movement of functions.
1429 0.4.2 ---------------------------------------------------------------------
1433 0.4.1 ---------------------------------------------------------------------
1437 0.4.0 ---------------------------------------------------------------------
1441 Link hysteresis as described in the RFC added.
1445 TC redundancy as described in the RFC added
1449 MPR redundancy as described in the RFC added
1453 The scheduler has been rewritten to register scheduled
1454 events(function pointers) dynamically.
1458 The parser has been rewritten to register parse functions
1459 on a pr. messagetype dynamically
1463 A wrapper for the malloc(3) syscal has been introduced.
1464 olsr_malloc(size_t, const char *) should ALWAYS be used.
1468 Lots of restructuring in headerfiles.
1469 Linux spesific code moved to subdirectory linux/
1470 FreeBSD code to be put in freebsd/
1471 LOTS of code restructured due to the rexrite of the scheduler
1476 Optimizing the MPR set as suggested in the RFC section
1477 8.3.1 point 5 added.
1481 Some bugs in MPR selection fixed.
1484 0.3.8 ---------------------------------------------------------------------
1488 HNA code completely rewritten!
1489 The old code was really bad! Now it is much cleaner implemented and
1491 One- and two-hop neighbor list structures rewritten. They now use
1492 the same hashed double-linked lists as the rest of the information
1497 Some code restructuring which resulted in the new files: timer.h,
1498 mantissa.c, mantissa.h, hashing.c, hashing.h, linux/net.c
1499 linux/net.h, linux/kernel_routes.c, linux/kernel_routes.h and some
1504 The bug causing errormessages on exit is fixed.
1505 The bug that caused initial HNA routes in the GUI to display a hopcount
1507 IPv6 HNA netmasks were all added as /128. It's fixed now.
1511 Turns out sitelocal address had to be preferred to avoid IPv6 header
1512 messing up link-sensing. Bug fixed
1515 0.3.7 ---------------------------------------------------------------------
1519 The entire TC set and MPR selector set code rewritten. Hashing and
1520 double linked lists added to the MID code.
1521 Lots of HNA code has been rewritten as well.
1525 When a node lost connectivity to a HNA GW all HNA entries to that gw
1526 was deleted. This has been fixed - and HNA entries only gets deleted
1528 Other HNA bugs have been fixed as well. But the whole HNA implementation
1533 There was a bug that caused holdingtime not to be properly recalculated
1534 when using non-default emission intervals.
1536 Forwarding and symmetric neighbors
1538 Seems I had misread the RFC on what a 1-hop symmetric neighbor is.
1539 Now the link-set is checked when a check for a symmetric neighbor
1540 is done. Not the 1 hop neighbor set as it used to be. This way
1541 the hack when receiving MID messages could be removed.
1545 Global addresses are now preferred. Sitelocal addresses are only used
1546 if no global addresses are found. There have been problems where
1547 the address set in the IP header of IPv6 packets do not match the
1548 address chosen by OLSR.
1552 The GUI is finally updated! It can now handle piggybacked messages
1553 and link sensing HELLO message format.
1556 0.3.6 ---------------------------------------------------------------------
1558 HNA support using IPv6
1560 HNA now works using IPv6 as well! Just add the network address and
1561 prefix in the HNA6 section in the configfile. The IPv6 HNA packets differ
1562 some from the IPv4 as they don't send the netmask but the prefix.
1565 NEW FILENAME FOR THE BINARY AND CONFIG FILE
1567 They are now called olsrd and olsrd.conf. I figured I'd use the olsrd
1568 name before somebody else started using it ;-)
1573 New options: DEBUG, HNA6 and IPC-CONNECT added to config file.
1578 A printf-wrapper has been introduced - debug level output handling
1579 is much more uniform now.
1580 The daemon should run fine in detached mode now(DEBUG 0)
1584 The GUI front-end can now connect and disconnect at any time while the
1585 daemon is running, if started using the -ipc switch or with IPC set to
1586 'yes' in the configfile.
1591 A small HNA bug fixed.
1594 0.3.5 ---------------------------------------------------------------------
1598 Forwarding jitter added. Messages are piggybacked if they arrive(and are to
1599 be forwarded) while there is data to be forwarded buffered.
1600 Added some bugfixes to support parsing of piggybacked messages as well.
1604 Fixed route calculation so that 2 hop neighbors are added. This smooths
1605 changes from 1 hop to 2 hop neighbor out. The old way one had to wait for
1606 a TC before the 2 hop neighbors were added.
1610 All neighbors received in HELLO messages are added to the two hop
1611 neighborhood. This helps smoothing out the 1-to-2 hop transition as well.
1615 MID calculation had to be updated due to the registering of two hop neighbors
1616 that are already one hop neighbors. They should not be considered when calculating
1621 Deletion of possible one hop neighbors registered on non main-addresses when
1622 first registering MID info from a node removed. This can not occur due
1623 to the fact that registering of neighbor nodes are done on main addresses
1625 Option to not forward messages on wired links on which they arrived removed.
1626 This is no longer usable to any degree when adding support for piggybacking
1627 of forwarded messages is to be implemented.
1631 Some unused parameters and commandline options were removed.
1635 0.3.3 ---------------------------------------------------------------------
1639 Added sending of empty TC messages if all MPR selectors are removed. Empty
1640 TC messages are sent for a TC_HOLD_TIME period as described in section
1645 Fixed HNA route calculations for IPv6. I forgot to upgrade this in 0.3.2
1649 -hnaint and -midint command line optionas added to set the interval
1650 of HNA and MID generation.
1654 As an optimization messages have not been forwarded on the received interface
1655 if this is registered as a non-WLAN interface. This causes problems for
1656 people using Ethernet-to-WLAN adapters. This optimization is now turned
1657 off by default. It can be activated using the -nofwlan option.
1661 THERE ARE SOME NASTY BUGS IN 0.3.2!
1662 Fixed a bug that caused 2 hop neighbors not to time out.
1663 Fixed a bug that caused a 1 hop neighbor timeout not to recalculate
1665 Fixed a small memleak in the MID set
1666 Fixed some smaller bugs.
1668 IPv6 functioning is not well tested in this release.
1670 0.3.2 ---------------------------------------------------------------------
1674 Updated HNA to be RFC compliant. This means that all received HNA tuples
1675 are registered and only the subset of unique entries(net/netmask) with
1676 the smallest hopcount is inserted into the routing table.
1680 User can specify configfile name using the -f switch.
1684 Fixed a link-sensing bug that caused problems when using MID nodes.
1686 0.3.1 ---------------------------------------------------------------------
1690 MPR calculation is now based on the willingness announced by nodes.
1694 The neighbor set does not have timeouts on entries any more. Creation
1695 and deletion of neighbor entries is done from the link-set as suggested
1700 Gotten rid of a lot of code that became more or less obsolete due to
1701 all the changes introduced in 0.3.0.
1705 Fixed a nasty bug concerning the sequence numbering of TC packets.
1706 Fixed some bugs regarding MPR calculation - and probably introduced
1707 a whole new species when implementing the willingness-based calculation ;-)
1710 0.3.0 ---------------------------------------------------------------------
1712 Due to the extensive amount of updates this release is versioned 0.3.0
1714 Duplicate table and forwarding
1716 The duplicate table functionality is totally rewritten in 100% RFC
1717 compliance. The forward algorithm specified in the RFC is implemented
1718 this meant rewriting much of the packet processing code. The daemon
1719 also forwards unknown packettypes now.
1721 Link sensing and neighbor processing
1723 Link sensing and neighbor processing was done in the same operation in the
1724 old code. Link sensing is now a mechanism of its own which is 100% RFC
1725 compliant. Neighbor processing and HELLO generation has been partly
1726 rewritten to be RFC compliant. Neighbors are now registered as either
1727 SYN or NOT_SYM. The NOT_NEIGH, SYM_NEIGH and MPR_NEIGH values are only
1728 used when building HELLO messages. Links are in one of the following states:
1729 UNSPEC_LINK, ASYM_LINK or SYM_LINK.
1730 HELLO messages now advertise link status of neighbors on the interface
1731 the message is transmitted.
1735 A node now dynamically calculates willingness based on powersource and
1736 possibly battery power. If the node is AC powered it announces a willingness
1737 of 6. If batterypowered the willingness is calculated as:
1739 Where P is percentage of power left.
1743 The daemon now tries to read its configuration from the file /etc/uolsrd.conf
1744 A "standard" configuration file is installed when doing 'make install'.
1745 This file should be edited to fit your needs.
1746 Command-line options can still be used to override the configuration form
1747 the file(ore if no config file is present).
1748 The -f switch can also be used to specify a configuration file.
1752 If AdvancedPowerManagemant(APM) is supported on your system the willingness
1753 of the node is dynamically calculated based upon the powerstatus of the node.
1754 MPR calculation based upon willingness is not done as of yet.
1758 A bugs in the TC processing fixed.
1762 Some serious HNA bugs fixed. These bugs caused a node to always choos the
1763 gateway with the larges hopcout :) More seriously - a bug caused looping
1764 of HNA messages in certain scenarios.
1766 Package sequence numbers
1768 These were added. Not much use as of now - but they're there(as specified
1773 Users can now specify the broadcast address to use. Useful if one wishes to
1774 use the 255.255.255.255 broadcast.
1778 0.2.5 ---------------------------------------------------------------------
1782 Htime and Vtime processing and handling added. Holding times used to be
1783 a static value for all nodes. Now every node can signal its vlidity time
1785 To achieve this mantissa/exponent calculation functionality was added.
1786 Messages now include Vtime(and Htime in HELLO) values in mantissa/exponent
1787 format instead of just zero. These values are as stated above, used as holding
1789 the GUI should be upgraded as well...
1793 The use of jitter in message generation intervals vere fixed.
1796 0.2.4 ---------------------------------------------------------------------
1800 Some bugs concerning sequence numbers in HELLO and MID message handling
1801 was fixed. Newly registered nodes in the neighbor and MID sets were
1802 initialized with a seqno of 0. When using a "wraparound" sequencenumber
1803 check(as defined in olsr_protocol.h) this can produce errors if a new
1804 node joins a network where existing nodes has seqnos >0x00FF.
1808 Some checks and copying of node addresses where done using sizeof(u_olsr32_t)
1809 which is 32 bits. This caused only the 32 firs bits of IPv6 addresses to
1810 be copied and checked.
