54 to see a complete history.
56 0.6.0 --------------------------------------------------------------------
58 Change in version number system. No more -rcX for release candidates and
59 -rX for bugfix releases. In future bugfix releases or updates of plugins
60 will increase the third digit of the version string while feature releases
61 will increase the first and/or the second one.
63 Markus Kittenberger <Markus.Kittenberger@gmx.at>
64 Henning Rogge <henning.rogge@fkie.fraunhofer.de>
65 - added NIIT kernel module support for sending IPv4 traffic over
66 IPv6 mesh networks. See README-Olsr-Extensions for more information.
67 - added SmartGateway support. OLSRd can now automatically build
68 IPIP tunnels towards the gateway to prevent gateway flapping.
69 See README-Olsr-Extensions for more information.

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

331 - Replaced "which" with a /bin/sh script snippet
333 PATCHES and CLEANUPS by Bernd Petrovitsch <bernd@firmix.at>
334 - Jens Nachtigall <nachtigall@web.de> suggested (and reminded) to use
335 olsrd.conf.default.lq as the default installed one.
336 It makes much more sense as - to the best of my(bernd's) knowledge - all
337 larger networks uses the LQ extensions. And new customers should better
338 be pushed in that direction.
339 - with the help of Patrick McCarty <mccartyp@gmail.com>, we got olsr to build
341 * OpenBSD'd `sed` is pretty conservative and doesn't understand 's|re|sub|'.
342 So we fall back to the old 's/re/sub/' and quote all '/' and '.' correctly
343 (which was the main reason to use '|').
344 And while I'm at it: Remove the useless $(CCACHE) from the $(CC) for
345 dependency generation and beautify (read: "$(strip)") $(CPPFLAGS).
346 * OpenBSD needs an explicit "#include <sys/types.h>" before
347 "#include <netinet/in.h>".
348 - fixed lib/secure/src/md5.h: This was broken as it had
349 "typedef unsigned long int UINT4;". "unsigned long int" is 8 bytes on x86_64.
350 We are using now the standardized types from <inttypes.h>.
351 - fixed warnings and improved lib/secure/src/md5.c:
352 * we are using memcpy() and memset() instead of the open-coded loops as
355 * added function prototypes for static functions
356 * moved static functions to the top so that their declaration is before
357 their use to allow gcc to inline if only used once.
358 It remains ugly - God knows why there are that so many useless
360 - Some minor and trivial cleanup: Added two functions to calculate the ETX
361 value from a struct tc_edge_entry and a struct link_entry, respectively.
362 And use them everywhere.
363 - added http://meshcube.org/nylon/utils/olsr-topology-view.pl into
364 lib/httpinfo/misc as suggested by Jens Nachtigall <nachtigall@web.de>
365 - Killed "struct olsrd_config *cnf" in src/cfgparser/olsrd_conf.h and replaced
366 it's usage with "olsr_cnf" from src/defs.h.
367 Serious cleanup: olsrd_get_default_cnf() does no longer initialize the global
368 "cnf" variable" but uses a local one which is returned as before. And
369 olsrd_parse_cnf() does no longer return the global variable it is working on.
370 - Merged "struct hna4_entry" and "struct hna6_entry" into
371 "struct local_hna_entry" (as "struct hna_entry" is a different thing)
372 Both have almost the same data (IP address + netmask/prefix) so we use
373 the quite new "struct olsr_ip_prefix" to store it.
374 Also merged the "hna4" and "hna6" pointer in "struct olsr_config" -
375 look at the global "olsr_cnf->ip_version".
376 - added a olsr_ip_prefix_to_string() function
377 - .h file cleanup: def.h does not longer include net_olsr.h because it
379 - more type safety: the macros COPY_IP() and COMP_IP are gone and replaced
380 with "=" or similar "normal" C operations. There are also now the inline
381 functions ip4cmp() and ip4equal() to work on "struct in_addr", ip6cmp()
382 and ip6equal() to work on "struct in6_addr" and ipcmp() and ip6equal()
383 to work on "union olsr_ip_addr".
384 Most (or even more precise: almost all) uses of COPY_IP() and COMP_IP()
385 are in "if (olsr_cnf->ip_version) { ... } else { ... }" anyway to
386 there is no reson to copy an IPv4 address effectively with
387 "memcpy(&dst, &src, 4)" or compare with memcmp(&a, &b, 4)" wher the
388 always "4" is stored in a variable inhibiting compiler optimization.
389 There is also the deprecated function genipcopy() mimicking the old
390 typeless COPY_IP() macro for the last few places where a cleanup is
392 There also lots of old macros left over (commented out of course) until
393 we are confident that everything works. And then I will kill them too.
394 - Fixed the misleading definition of "v4" in "struct olsr_ip_addr" fom
395 "olsr_u32_t" (in network-byteorder!) to "struct in_addr". Lots of
396 temporary variables to call inet_ntoa()/inet_ptoa() vanished .....
397 - We have now ip4_to_string(), ip6_to_string() and olsr_ip_to_string()
398 to print a "struct in_addr", "struct in6_addr" and "union olsr_ip_addr"
399 into a string buffer.
400 - cleanup: olsr_ip_to_string() and similar non-reentrant functions now must
401 get a target buffer. To ease that, there is the "struct ipaddr_str"
402 which is large enough for all of them (read: for an IPv6 address). This
403 also removes the cyclic buffer there.
404 All of these function return a "const char *" which can be directly used
405 for printf(3) and friends.
406 - const'ified more functions
407 - converted the source to UTF-8.
408 - "struct sig_msg" uses an olsr_u8_t for a byte array (and not "char")
409 - force the few inline function to always be inlined.
410 - #ifdef the body of the olsr_print_hna_set() and olsr_print_neighbor_table()
412 - declare "int_addr", "int_netmask" and "int_broadaddr" in "struct interface"
413 as "struct sockaddr_in" since it is that what we actually want there (and
414 it is similar to the IPv6 code).
415 - updated the olsrd.conf.default.lq-fisheye to the Debian-deliverd version
416 after recent discussions olsr-dev@olsr.org
417 - use "inline_avl_comp_ipv4()" in "avl_comp_ipv4()"
418 - clean up the routes on more signals. Basically we want to do this on all
419 signals which terminate the program.
420 - killed a superflous global buffer in src/main.c
421 - made inline functions from avl_walk_{first,last,next,prev} and created
422 "const" versions of it. inline_avl_comp_ipv4() is now also an inline function
424 - created a typedef's for various function pointers - much easier to read.
425 - cleanup: compare tree->comp (adn other pointers)) to NULL (and not 0)
426 - killed superflous "return"s at the end of void functions
427 - const'ified more parameters in many more functions in the .h and
429 - init-functions with constant or ignored return values are "void"
430 - created a typedef fro the callback in "struct export_route_entry"
432 - moved the initialization of the {add,chg,del}_kernel_list variables
433 into process_routes.c. So they are now "static" there.
434 - olsr_export_{add,del}_route{,6} are now static in process_routes.c
435 since they are not used elsewhere.
436 - olsr_addroute_add_function() and olsr_deldroute_add_function() were
437 almost identical - made one function out of it.
438 Same for olsr_addroute_del_function() and olsr_deldroute_del_function().
439 - fixed the sort order in avl_comp_ipv4_prefix(): We compare now the IPv4
440 values in host byte order (and not network byte order). So the route
441 list in the e.g. httpinfo plugin is now nicely sorted.
442 - fixed and improved the `gcc-warnings` script:
443 * support older gcc's (as on Debian/Sarge) as they have slightly different
445 * removed superflous lines
446 * replaced the call of `sed` with shell built-in features fixing syntax
447 errors on Debian/Sarge
448 * set all locale-relevant variables to "C" (just to be sure)
449 - consolidated ip{4,6,}{cmp,equal}: all are nwo inline functions using only
450 the minimal necessary operations. Thanks to Hannes Gredler
451 <hannes@gedler.at> and Sven-Ola Tuecke <mail2news@commando.de> for pointing
452 that out and suggesting the `inline`, respectively.
453 use ip{4,}cmp in lq_avl.[ch] to resue the code. inline_avl_comp_ipv4
454 is superflous now (and replaced by ip4cmp) and use the global MIN and MAX
455 macro instead of AVLMIN and AVLMAX
456 - killed netmasks from the IPv4 part of the code and use the prefixlen there
457 (similar to thte IPv6 part). Manymore details on
458 http://lists.olsr.org/pipermail/olsr-dev/2007-November/001464.html
459 - removed the superflous "open_ipc" field from the "struct olsrd_config" as
460 it contains only the equivalent of "olsr_cnf->debug_level > 1".
461 - inspired by Sven-Ola Tuecke: avoid a bash'ism (i.e. "OPTS="${OPTS//$opt}") in
462 gcc-warnings and ld-warnings. But we do not replace it with `sed` (since it
463 costs a fork(2) and an exec(3)) but also with shell code which doesn't use
464 any external program.
465 - added configuration file support for "flat fib metrics".
467 0.5.4 ---------------------------------------------------------------------
469 QUAGGA by Immo 'FaUl' Wehrenberg <immo.olsr@do.bundessicherheitsministerium.de>
470 - updated to svn version 33
472 BMF PLUGIN by Erik Tromp <erik_tromp@hotmail.com>
474 - updated to latest plugin interfaces changes and killed warnings (by Bernd
475 Petrovitsch <bernd@firmix.at>)
477 PATCH by Hannes Gredler <hannes@gredler.at> which rewrites the route handling.
481 - get rid of separate routing tables for HNA and per-node routes, everything is
482 now unified in an AVL routing tree (&routingtree)
484 - introduce walking macros (OLSR_FOR_ALL_RT_ENTRIES()) that hide the internal
485 structure of the RIB for making life of the plugin authors easier.
487 - get rid of different SPF implementations for LQ and non-LQ code paths. a
488 non-LQ edge is simply substituted with a cost of 1.0
490 - get rid of host masks - a new data type olsr_prefix is introduced which is
491 basically an ip address plus a prefix length.
493 do not install the metric in the kernel FIB - for the kernel its pointless
494 if the route gets installed with a metric of N or M.
496 we do not need to update the kernel FIB if we have hop count only changes
497 (for example if there is a reroute action further downstream)
499 the only things which triggers a kernel FIB route update is a next hop
500 change (a next hop is neighboring gateway router plus an interface).
502 all OLSR routes are installed with a metric of 2
504 - separate between rt_entry and rt_path - the former is a route installed in the
505 kernel with an next hop. the latter is a candidate for best path selection
506 after SPF calculation has been done. in the rt_entry we keep a pointer to the
507 best_path and also to the next hop that was installed in the kernel FIB.
509 we always keep all originator of a route, if a route originator goes away we
510 can easy recompute the best path for the route.
512 the next hop in the rt_entry gets only updated upon a successful route_add
513 call - that way we always remember what next hop to delete.
515 stray routes should be history now.
517 - tweak the linked list toolkit to operate on circular lists.
519 - get rid of malloc calls for building the kernel update list. the list node is
520 now embedded in the rt_entry.
522 - introduce three queues (add/chg/del) for kernel updates.
524 - for neighbor route dependency tracking the neighbor routes are queued first or
525 last (depending on which queue you work on)
527 - rework all the plugins which directly manipulate rt entries.
529 - rework the plugins that read from the routing table (most notably nameserver,
530 httpinfo and quagga plugin)
532 - lots of comments that explains the intentions and purpose of this code-piece.
534 non RT related stuff:
535 - use a list rather than a tree for storing the post-SPF results, which further
536 improves the raw-SPF runtime.
538 - add display of SPF runtime (masked behind #ifdef SPF_PROFILING)
540 - http://gredler.at/download/olsrd/neighbor_routes3.diff: This updates the own
541 IP address (read: the main address) after changes (e.g. on
542 `ifup wlan0; sleep 1; ifdown wlan0`) and kills the
543 olsr_fill_routing_table_with_neighbors() function.
545 And Sven-Ola Tuecke <mail2news@commando.de> fixed an instability issue on interface
546 up/down operations (see 102-olsrd-rt-refactoring-fixes.patch below) and a missing
549 PATCH by Hannes Gredler <hannes@gredler.at> which "consolidates
550 the link-state database and the spf-calculation in order
551 to calculate routes more efficiently".
554 - use the link-state (tc) database for SPF calculations rather than
555 replicating the notion of vertices and edges for a SPF run.
556 this heavily reduces malloc() calls and shrinks the total CPU
557 load of the route calculation path between 60%-80%.
560 PATCHES by Sven-Ola Tuecke <mail2news@commando.de> to be found on from
561 http://download-master.berlin.freifunk.net/sven-ola/nylon/packages/olsrd/files/
562 - 102-olsrd-rt-refactoring-fixes.patch
563 Because you changed a lot of basics: It's time to handle a general
564 flaw in the routing system. Plase take a look at chk_if_changed(). This
565 will free() any "struct interface" pointer without warning at any time.
566 This is why it's possile to SEGV olsrd with a simple "ifdown xxx".
567 The patch replaces the (maybe) invalid pointer with an index reference
568 "iif_index". You can always ask the OS for a name. Please note, that I do
569 not have a working BSD toolchain, so I've placed an #error in the IPv6
570 BSD-part where the author/porter has started to hack something funny.
572 - 110-olsrd-double-wlancard-neigh-hack.patch:
573 This is a hack for Nodes having to wifi cards with the same channel,
574 bssid, IP-Range etc. If two nodes can see each other by means of two
575 possible links (here: two wifi cards with equal config), a bug is triggered
576 with the Neigh-is-SYM detections. This small little hack prevents this.
578 - 112-olsrd-nameservice-fixemptyname.patch:
579 This is an addon to my lat/lon stuff which will prevent olsrd from
580 running (oops?) if no hostname is given and the nameservice plugin
583 - 113-olsrd-dyngwplain-pluginvers5.patch:
584 This updates the dyngwplain plugin to the new Plugin Iface
586 - 140-olsrd-arprefreshed.patch:
587 This is a new one. Opens a packet socket and listen to UDP(698), extract
588 the sender MAC and refreshes the ARP cache whith that. Should speedup
589 especially in cases, if you initially try to use a longer routing path which
590 normally triggers a "ARP-Lookup-Chain".
591 - 106-olsrd-nameserviceparams.patch:
592 This patch converts more plugins to the new interface version.
593 - 104-olsrd-policy-routing.patch
594 Reworked this one to discard GPL helper functions. Also checked IPv6 and
595 re-included the IPC hookup. The patch adds a "RtTable [number]" for
596 /etc/olsrd.conf which is simply the Linux
597 policy routing table to use. Defaults to 254 (== main).
598 This patch was modified/clenaed up by <bernd@firmix.at> to use "#if"
599 instead of "#ifdef" as it's more robust against typos.
600 - 110-olsrd-fixpacketprint.patch, 112-olsrd-nameservice-fixemptyname.patch,
601 113-olsrd-txtinfo-fixhttpget.patch, 114-olsrd-timeoutlimit.patch,
602 115-olsrd-nameserviceparamfix.patch and
603 116-olsrd-fix-pluginparam-addons.patch fixing the compilation warning
604 on 64bit and lots of other improvements.
605 - "Save the fish" patch: Avoid forwarding of packets with too low TTL. This
606 kills lots of packet forwarding storms.
607 NB: The oneliner was applied by hand by BP and formatted to look (in BPs O)
610 PATCH by Arnd Hannemann <hannemann@i4.informatik.rwth-aachen.de>
611 olsr_makefile_make_use_of_exename.patch
612 - This patch makes sure that the EXENAME variable of Makefile.inc is used
615 PATCHES by John Hay <jhay@meraka.org.za>
616 - update to new FreeBSD WLAN API
617 - do not require /bin/bash, use /bin/sh
618 - Fixed alignment so that olsrd runs on FreeBSD/arm
619 - allow more interface in an IPv6 subnet on FreeBSD
620 - use PREFIX and DESTDIR as all the other Makefile.$OS also for FreeBSD
621 - make txtinfo plugin work with IPv6
623 PATCH by Andreas Jacobs <jacobs@i4.informatik.rwth-aachen.de>
624 - fix the loss link quality calculation for "windows size % 4 != 0"
626 PATCH by Acinonyx <acinonyxs@yahoo.gr>
627 - Bug fix: include $(TOPDIR)/Makefile.inc at the begin in the Quagga plugin
629 PATCH by David Cornejo <dcornejo@gmail.com>
630 - fixed an "+=" of an uninitialized variable (detected with/by the
633 BUG reported by Aaron Kaplan <aaron@lo-res.org>
634 - BSD-xargs doesn't know "-r".
636 PATCHES and CLEANUPS by Bernd Petrovitsch <bernd@firmix.at>
637 - Made a function from the ME_TO_DOUBLE() macro (in src/mantissa.h).
638 This saves code throughout the code even on i386 and will even more
639 on architectures without floating point units and "-msoft-float".
640 - And the mathemathics in src/mantissa.h is reformulated to minimize
641 floating point operations to save CPU power - especially on embedded
643 - I rewrote the half of src/lq_packet.[ch] which deals with incoming
644 packets. This was triggered with performance output of gcc produced
645 by Sven-Ola Tuecke at CCCamp07.
646 This kills *lots* of (more than) superflous malloc()s and the same
647 number of (free()s). And it also kills some code and copying around of
649 - Make it compile without warning with flex-2.5.33 (to be found on Fedora 7
650 and Gentoo in Sep-2007) again.
652 - converted the dyn_gw plugin to plugin interface version 5 (which leaves
653 the quagga plugion as the last with the old one).
654 - paving the way to activate -Wshadow, much more to do
655 - const-ify parameters here and there
656 - use NULL for pointers (and not "0")
657 - Killed "extern" declarations in (not generated) .c files
659 - Based on a patch by Gianni Costanzi <gianni.costanzi@gmail.com> (so credits
660 and thanks have to go there):
661 added OS_CFLAG_PTHREAD Makefile variable since gcc (on Linux) requests this
664 - I added definitions to all OS-specific Makefile.$OS with the value similar
665 to the value in OS_LIB_PTHREAD (either empty or "-pthread").
666 - The variable is added to CPPFLAGS (and not CFLAGS) since CPPFLAGS is used
667 for all cpp and gcc calls (and gcc's man page indicates that it sets
668 variables for both of them).
670 0.5.3 ---------------------------------------------------------------------
673 Ignacio GarcÃa Pérez <iggarpe@terra.es> found a serious bug in the dot-draw
674 plugin and identified it's source.
677 The bmf plugin wanted to kill a not-started thread and this causes a segmentation
678 violation. This happens if the old plugin interface support is not compiled in
679 and one uses - or more asccurate: wants to use - the bmf plugin which uses that
680 ATM. Thanks to Cedric Krier <ced@ced.homedns.org> for reporting this.
683 The dependencies (*.d files) are now properly generated and used. And they also
684 dependen on the Makefile in the current directory and the Makefile.inc so that
685 changes there also lead to new compilation.
686 Remember: We support "ccache" so install it to save lot of meaningless recompiles
687 if nothing (as seen by the real C compiler, i.e. after the C preprocessor) has
691 Linux/IA64 and Linux/HPPA also need "-fPIC".
694 - olsr_switch does no longer generate warnings
695 - olsr_switch is also built with "build_all" and cleaned with "uberclean"
696 - More "const" all over the place.
697 - More "static" for local functions and variables.
698 - Killed an unnecessary "static" variable.
700 0.5.2 ---------------------------------------------------------------------
703 Sven-Ola Tuecke found a serious bug of the class "show stopper" and sent a patch.
706 Plugins handle parameters quite individually (case-sensitive vs case-insensitive,
707 different parsing functions for the same values, etc.). Plugin Interface version 5
708 now exports a table of { parameter-name, parsing-function, addr-of-storage } and
709 it's size. Common functions should be shared.
711 0.5.1 ---------------------------------------------------------------------
714 Upgrade to olsr-bmf 1.5 from Erik Tromp <erik_tromp@hotmail.com>
716 latitude/longitude support is now in the nameservice plugin done by
717 Sven-Ola Tuecke <mail2news@commando.de>
719 added the spf refactoring patch from Hannes Gredler <hannes@gredler.at> which
720 saves a noteworthy amount of CPU time. To quote him:
722 1. use of an AVL tree as a min-heap implementation
724 as a means for efficient sorting.
725 (the etx metric is used as the key in the candidate tree)
727 2. next-hop propagation
729 rather than tracking the previous node in olsr_relax()
730 i have changed that model and pre-populate all one-hop neighbors
731 with their own IP address as 'next-hop' and pull that
732 pointer up once new paths are explored.
734 as a result no walker for counting hops and extracting next-hops
735 is required - it turns out at this is slighly more efficient
736 than the existing behaviour (even with the cache applied).
740 * moved a only locally needed hack from "union olsr_ip_addr" into the only place
741 where it is needed in hashing.c
743 0.5.0 ---------------------------------------------------------------------
745 APPLIED PATCHES FROM FREIFUNK-FIRMWARE
746 libsmake, dyngwplain, nameservices+services, tzxtinfo, quagga, quagga-routehandler,
747 optimize, fixes from Eric Tromp and Sven-Ola Tuecke, CPU-optimize, secure key, HNA-IP
750 removed hardcoded limit on the number of interfaces (at least in the Unix part)
751 made Makefile targets much more consistent
754 put Bmf-1.3 plugin into it
758 Patch from John Hay applied.
762 0.4.10 --------------------------------------------------------------------
764 OLSR NETWORK SIMULATOR
766 An application called olsr_switch(sorry for the nameclash with the win32
767 GUI) has been added. If olsrd is ran using the -hint option it can now
768 connect to olsr_switch and be part of a virtual network. This means
769 that multiple instances can be ran at the same host! The olsr_switch
770 application allows the user to define link variables on all viritual
771 links in the network, creating all possible topologies. Read more in
774 EXPERIMENTAL FISH EYE ALGORITHM
776 An experimental algorithm for TTL settings on TC messages has
777 been added. Read more in the corresponding README file.
781 olsrd now also compiles on OpenBSD systems. Thanks a lot to Holger
782 Mauermann for the patches!
786 Bruno has rewritten the make system. OS detection is now done
787 automagically and the general design is much improved.
789 IP ADDRESS VALIDATION
791 Olsrd now maintains a set of IP addresses that is considered
792 invalid. Checks against this set is done on all received
793 OLSR packets announced originator addresses. The dataset can
794 be updated dynamically.
798 Updated interface version to 3 and added more noticeable warning
799 for version missmatch.
803 The dependency on the math lib came from the use of pow(3) in the
804 mantissa/exponent calculation. The calls to pow in this long forgotten
805 code, was very unnessecarry. The pow calls are replaced with bitwise
806 shifts and -lm is no longer needed.
808 ICMP REDIRECTS ON LINUX
810 On Linux systems "0" is now also written to the all/send_redirects
811 procfile and not only the pr. interface ones. Hopefully this resolves
812 problems reported with systems still sending ICMP redirects.
816 - Fixed init of IPv6 addrtype variable. It used to be uninitialized,
817 causing it to default to site-local and have some weird side-effects.
818 - Fixed crash when changing IPv6 address at run-time
819 - Fixed a bug that prevented setting willingness 0 in the configfile
820 - Fixed bad handling of missing command line arguments
821 - Did various updates to prevent assertion when a neighbor
822 has changed IP and sends HELLO before its olsrd precess has detected
824 - Fixed return value check on times(2) calls in the scheduler
825 - Fixed bug(s) that could cause crash when an interface was brought
826 down while olsrd was running.
827 - Removed the silent (read: unchecked) hard limit of 16 interfaces.
828 - Compiles now cleanly on 64bit (e.g. x86_64).
830 0.4.9 ---------------------------------------------------------------------
834 The MID database is now also indexed by alias addresses. this makes
835 look-ups of main addresses based on alias addresses _much_ faster.
836 The mid_lookup_main_addr function alone has gone from >30% of the
837 total CPU time used by olsrd to <1%.
838 PLUGIN DEVELOPERS: datatypes for MID entries has been changed.
840 Routing table calculation in the LQ case now uses balanced binary
841 trees instead of linked lists, which makes look-ups much faster.
843 The debug output function olsr_printf() is not used by olsrd
844 internals any more. Instead the macro OLSR_PRINTF is to be used.
845 This macro does debug level testing _before_ doing any function
846 calls(both printf itself and parameters to printf). This is a much
847 more optimized way of doing debug output. In addition olsrd can
848 be built without any debug output code if doing 'make NODEBUG=1'.
852 Validity times for dataset entries are now set using the clock_t type
853 (used to be struct timeval). This data is now fetched from the times(2)
854 function instead of gettimeofday(2). This prevents possible problems
855 if the system time is changed.
856 PLUGIN DEVELOPERS: Note that datatypes for close to all dataset entries
857 (link, neighbor, mid, hna, tc etc.) has been changed!!
861 Multiple interfaces can now use the same interface configuration block.
863 Interface "if0" "if1" "if2"
868 Interface configurations now also support the "Weight" directive. When
869 olsrd finds multiple links to a neighbor it will choose the link
870 going via the interface with the lowest weight. Olsrd normally
871 sets this weight dynamically based on interface characteristics,
872 but if the user wishes to set a fixed weight in a interface(or
873 a group of interfaces), this directive is now available.
875 Moreover, interface configurations now support the "LinkQualityMult"
876 directive. It takes an IP address and a multiplier as arguments.
884 LinkQualityMult 192.168.0.1 0.7
885 LinkQualityMult default 0.5
890 The idea is to make certain links via the configured interface
891 artificially worse or better than they really are. The first parameter
892 specifies the IP address of a neighbour interface. The second
893 parameter is the multiplier to be applied to the link to the specified
896 After we have derived the link quality from the packet loss among the
897 packets received from the specified neighbour interface, we multiply
898 the link quality by the given multiplier. So, the multiplier changes
899 the LQ value that we use when determining the ETX, which is 1 / (LQ *
902 If "default" is given as the IP address then the multiplier applies to
903 all links via the configured interface. Note, however, that olsrd only
904 assigns one multiplier to each link. It does so in the following way.
906 * If there is a "LinkQualityMult" line that matches the IP address of
907 the link's neighbour interface, then use the multiplier in this
910 * If there isn't any matching line, then look for a "default" line. If
911 there is a "default" line, then use the multiplier in this "default"
914 * Otherwise use 1.0, i.e. do not modify the LQ value at all.
916 Hence, a line with an IP address has priority over a "default" line.
918 In the above example, the LQ value of the link between the local
919 interface if0 and the neighbour interface 192.168.0.1 would be
920 multiplied by 0.7. All other links between the local interface if0 and
921 a neighbour interface would be multiplied by 0.5.
925 The socket option IPV6_V6ONLY is now set on IPv6 sockets in linux.
926 This means that olsrd will no longer receive IPv4 traffic when
927 running in IPv6 mode.
928 This should enable users to actually run one olsrd instance using
929 IPv6 and one using IPv4 at the same time :)
933 The httpinfo, dyn_gw and dot_draw plugins now all include olsrd
934 headerfiles directly. A plugin should define OLSR_PLUGIN before
935 including olsrd headers. Doing things this way removed the
936 redundant datatype definitions that has so often caused trouble
937 when things has been updated in olsrd.
941 olsrd now also compiles on NetBSD systems. Use 'make OS=nbsd' to
942 build. This port is not very well tested and feedback is greatly
945 EXPERIMENTAL MULTI-INTERFACE CODE FOR FREEBSD
947 Experimental code using libnet can be compiled in allowing multiple
948 interfaces to be used in FreeBSD. You enable this by compiling using
949 OS=fbsd-ll. You must have libnet-devel installed for this to work
950 (/usr/ports/net/libnet-devel).
954 - WLAN devices are now detected in FreeBSD
955 - First specified interfaces IP is used as main address.
956 - Broadcastflag is not checked on interface if fixed broadcast is
958 - Removed Linux link layer code as this was not really in use.
959 - Added -nofork command line option
963 - Link sensing now works according to announced vtime from
964 neighbors. Previously links going symmetric->asymmetric
965 were not necessarily detected until the holding time expired.
966 - A bug in route addition/removal that could lead to routes
967 using GWs being added before the actual route to the GW
968 was set up, has been fixed.
969 - A bug in the interface selection in route calculation has been
970 fixed. New routes are no longer added prior to deleting old ones,
971 since this caused trouble.
972 - A bug in the IPv6 multicast address configuration has been fixed.
973 This caused olsrd not to work with global IPv6 addresses.
974 - A bug in the IPv6 prefix-from IPaddr function has been fixed. This
975 bug caused HNA prefixes to always be calculated to 0.
976 - If a 2-hop neighbor is also a 1-hop neighbor, a bug made olsrd
977 prefer a bad direct link to a better link via an MPR.
978 - If a link or interface lookup failed, olsrd crashed.
979 - Fixed a crash in the LQ packet generation code based on a
980 signed/unsigned integer comparison.
983 0.4.8 ---------------------------------------------------------------------
987 Olsrd is now distributed under a BSD style license. We believe olsrd will
988 be better off using this license as it opens up for commercial players
989 to use olsrd freely in their products. In the end this will lead to
990 this kind of users doing serious testing and bug fixing of olsrd.
992 ETX-LIKE LINK QUALITY DETECTION
994 We can now determine the packet loss on a link by looking at the serial
995 numbers of the OLSR messages received from a neighbor. This tells us how
996 many packets get through from our neighbor to us. We use a new extended
997 kind of HELLO messages (LQ_HELLO messages, LQ = link quality) to broadcast
998 the link quality that we have determined on our end of the link to our
999 neighbors. So do our neighbors, and we as well as they end up with an
1000 idea of how good the link is in both directions. From the LQ_HELLOs we
1001 also learn the link quality between our neighbors and our two-hop neigh-
1002 bors. In this way we can select those neighbors as MPRs that have the
1003 best links to our two-hop neighbors. To distribute the link quality
1004 throughout the network, we use a new extended version of TC messages
1005 (LQ_TC messages). They contain the qualities at both ends of each of our
1006 links. Nodes can then run Dijkstra's algorithm to find a path between
1007 themselves and other nodes that minimizes the packet loss.
1009 If the newly introduced "LinkQualityLevel" is set to zero in the
1010 configuration file, link quality is not used and the daemon behaves as
1011 before, i.e. as specified by the OLSR RFC. If this parameter is set
1012 to 1, LQ_HELLOs and LQ_TCs are used instead of HELLOs and TCs, link
1013 quality is measured and MPRs are selected based on the link qualities.
1014 If this parameter is set to 2, the routing table is additionally
1015 calculated based on the link qualities.
1017 Setting "LinkQualityLevel" to a non-zero value BREAKS COMPATIBILITY. You
1018 will then not be able to participate in RFC-conformant OLSR networks
1019 any longer. This is because we use LQ_HELLOs and LQ_TCs instead of HELLOs
1020 and TCs in this case.
1022 It's best practice to set "LinkQualityLevel" to the same value on all
1025 When determining the quality of a link olsrd only considers a given
1026 number of most recent OLSR packets received from its neighbors. By
1027 default, olsrd looks at the 10 most recent OLSR packets. This can be
1028 changed via the "LinkQualityWinSize" configuration option. Values
1029 between 3 and 128 are legal.
1031 NEW CONFIGFILE PARSER/FORMAT/SCHEME
1033 A whole new config file syntax and parser is introduced with this
1034 release. The parser is generated using flex and bison and it is
1035 designed to be very modular. The parser can be compiled as either
1036 a standalone binary, a shared library or as part of olsrd. This way
1037 other applications can parse and generate olsrd configuration files
1038 only by linking to the dynamic library.
1039 In the new configfile options can be set pr. interface, plugin
1040 parameters can be set, more IPC options can be set...and more.
1041 The syntax is documented in the olsrd.conf(5) manual page found
1042 in the files/ directory.
1043 Olsrd internals now uses a single struct, as returned by the config
1044 parser, for all configuration in runtime. this means that updating
1045 values in this struct will dynamically update olsrd operation. It
1046 also means that all configuration is now kept in one place instead
1047 of spread all across the place.
1049 FREEBSD AND MAC OSX PORT
1051 This version offers an initial port of olsrd to FreeBSD and Mac OS
1052 X. Like the Windows port it currently does not support IPv6. As this
1053 is a very first try at supporting FreeBSD and Mac OS X, this port is
1054 probably not as reliable as the Linux version. We'd greatly appreciate
1055 feedback and bug reports. To compile you need GNU make. Then simply
1056 run "gmake OS=fbsd" to build the executable.
1060 The makefiles used to build olsrd have been rewritten and now includes
1061 dependency file generation using makedep.
1065 Tables are now only printed if changes occur, so there are no longer
1066 any periodical output when using a debuglevel >0. A "heartbeat" is
1067 now printed to STDOUT(if it is a terminal) in the form of a rotating
1068 line to show that olsrd is actually operating.
1069 Adding "ClearScreen yes" to the configuration file clears the screen
1070 each time before the debug output shows updated information. This
1071 makes the debug output easier to read in many cases. "ClearScreen no"
1072 is the default, if no "ClearScreen" directive is given in the
1077 There are some changes in the plugin interface. It is now at
1078 version 2. Plugin specific parameters from the configfile
1079 using the PlParam option, will now be passed on to plugins.
1080 To receive such parameters a plugin must implement a function:
1082 register_olsr_param(char *key, char *value)
1083 to which parameter pairs will be passed.
1087 Olsrd no longer uses any thread library on its operation. Everything
1088 now happens in the main thread allowing for use of olsrd on platforms
1089 with no thread library.
1091 ACPI SUPPORT IN WILLINGNESS CALCULATION(LINUX)
1093 The willingness calculation for Linux, now also supports the more
1094 modern ACPI proc interface in addition to APM. This is not well
1095 tested and feedback is appreciated!
1099 Various options regarding IPC connections can now be set in the
1100 configfile. The options are max connections, allowed unicast
1101 hosts and allowed net-ranges.
1105 Much of the message generation and net output code is rewritten.
1106 Sending of partial messages should now work 100%. Also TC, MID
1107 and HNA messages are now cached for a random amount of time
1108 before transmitted - this often leads to the situation where these
1109 messages are sent together with an HELLO message, which is highly
1110 desirable since it saves network resources.
1111 PLUGIN DEVELOPERS must note that the buffers and size variables
1112 used in net output is no longer directly accessible!
1114 NET OUTPUT CODE REWRITTEN
1116 Every interface now has one outputbuffer registered. This allows
1117 messages to be "cached" as explained above, so that multiple
1118 messages are stacked together.
1119 Also the outputbuffer and size are no longer accessible directly,
1120 an API is available to plugins(and olsr code).
1122 OS DEPENDENT NETWORK INTERFACE
1124 The OS dependent network functions are now defined in net_os.h
1125 instead of being mixed up with internal network functions
1130 A bug that caused the announced ANSN sequence number to never stop
1131 being increased when a change in the MPR selector set was detected
1132 has been fixed. Another TC related bug that caused timed out TC
1133 entries not to be deleted from the routing table in certain cases
1134 has also been fixed. These bugs could cause unstable routes.
1135 A bug that in many cases caused the wrong routes to be deleted
1136 when using IPv6 has been fixed.
1139 0.4.7 ---------------------------------------------------------------------
1141 NATIVE WINDOWS GUI AND INSTALLER
1143 We now have a native Windows GUI. The GTK+ version is no longer
1144 supported on Windows. The new native GUI is pretty compact as it does
1145 not require the GTK+ runtime DLLs. In addition to monitoring olsrds
1146 state the GUI offers an easy way for novice users to configure
1147 olsrd. It's pretty self-explanatory. Have a look at README-WIN32.txt
1148 for details. The Windows version now also comes with an installer
1149 based on the freely available Nullsoft Scriptable Install System
1150 (NSIS). Looks like the Windows port is becoming more and more
1153 WIRELESS INTERFACE DETECTION ON WINDOWS
1155 Like the Linux version the Windows port is now able to tell WLAN
1156 interfaces from wired interfaces. We can now, for example, set
1157 different HELLO intervals for WLAN interfaces and wired interfaces,
1162 The order of updates of calculated routes is swapped. Now new routes
1163 are added prior to deleting old ones. This could fix issues where
1164 in some very very few cases one could experiment loss of routes.
1168 There were quite some bugs in IPv6 operation in 0.4.6. These are
1169 the bugs that were fixed:
1170 - HNA message parsing did not work.
1171 - Some IPv6 addresses were printed as IPv4 addresses in the
1173 - The '-dispin' option now works again.
1174 - A filedescriptor leak in the IPv6 interface detection caused
1178 0.4.6 ---------------------------------------------------------------------
1182 Read the README-WIN32.txt file!
1184 DYNAMIC NETWORK INTERFACE UPDATES
1186 Network interfaces can now be updated and removed/added at
1187 runtime. Olsrd will check all interfaces specified in the config
1188 file or on the command-line, every 5 seconds. If updates
1189 occur, olsrd will register this and update the necessary data.
1190 If interfaces are removed or added, olsrd will detect this
1191 and configure the interfaces. If an interface is removed
1192 olsrd will continue to check the interface, so if say, a PCMCIA
1193 card is removed and later on reinserted(and given the same name),
1194 olsrd will detect this and start running on it again.
1196 Note that olsrd will now run even if no interfaces are detected.
1198 ROUTE CALCULATION UPDATE
1200 All 1 hop neighbor addresses that are not directly reachable trough
1201 a symmetric link in the link set will now be added with a GW in the
1202 routing table. this GW will be an interface address from a registered
1203 symmetric link to the neighbor.
1207 Alias addresses are now registered in the link set processing
1208 if available. This is not to pretty(since the vtime has to
1209 be a mere guess) but it gives faster initial route updates.
1210 If a HELLO is received(at initial registration) from an IP
1211 that is not the same as the one set as main address in the
1212 received HELLO header, then the IP from which the HELLO was
1213 received will be registered as an alias of the main address
1214 set in the HELLO header. The default vtime is set to 15 secs.
1218 All OS dependent interface configuration code is now located in
1219 OS/ifnet.c(that would be linux/ifnet.c if using GNU/Linux).
1220 The functions are available trough the headerfile src/ifnet.h
1224 - Some timer issues fixed
1225 - Got rid of the global socket descriptors
1226 - Updated indexing of network interfaces
1227 - Introduced a global socket to use for ioctl calls(ioctl_s)
1228 - Removed upper limit for interfaces to use
1229 - Point-to-point interfaces are now allowed
1230 - The main select(2) loop now uses a timeout
1231 - A small bugfix in the select fd-set update code
1232 - Some bugfixes in the configuration file parsing
1233 - stdout/stderr are now set to not be buffered
1234 - A bugfix in the MID generation regarding seq. numbering
1238 A new set of functions that are called whenever a change in the
1239 interface configuration(update, addition, removal) is made is
1241 These functions are added and removed very much like the ptf
1242 functions. Available trough the functions add_ifchgf and del_ifchgf.
1244 OBS OBS OBS!!! PLUGIN DEVELOPERS READ THIS!!!!
1246 The interface struct(declared in interfaces.h) has changed.
1247 Plugin developers must update plugins that uses the interface
1250 The headerfile olsr_plugin_io.h which contains the plugin interface
1251 commands now contains a revision list where all changes are
1255 0.4.5 ---------------------------------------------------------------------
1259 A plugin that generates and checks message signatures is added.
1262 PLUGIN: TOPOLOGY GRAPH
1264 A plugin that generates output of the topology in the dot format
1265 is added. See lib/dot_draw
1269 Some optimizations done that should cause fewer route recalculations.
1273 Some bugs reported by Takafumi Tanaka fixed.
1275 RESTORATION OF NETWORK SETTINGS
1277 Network settings like disabling of ICMP redirects and spoof filter, are
1278 now restored at exit by olsrd.
1282 Nodes would in certain scenarios retransmit messages originating for
1283 themselves. This was a RFC incompliance. Reported by Ingmar Baumgart.
1287 No longer setting the HELLO interval of non-wlan interfaces as a multiplier
1288 of the wlan interval. The interval is set seperatly now.
1289 Due to this there are some updates in the configfile imperatives.
1293 Some new macros introduced for table insertion and removal and IP
1294 copying and comparison.
1298 IPv6 bugfixes in the GUI.
1301 0.4.4 ---------------------------------------------------------------------
1305 Routes are no longer added via neighbors declaring a willingness
1308 LINK SENSING AND ROUTE CALCULATION
1310 Link sensing and route calculation has been updated to handle
1311 multiple links between hosts in a sane way.
1315 IP spoof filtering is disabled on the interfaces which olsrd runs.
1316 These settings are not restored!
1320 ICMP redirect message generation is disabled on the interfaces
1322 These settings are not restored!
1324 CONFIGFILE OPTIONS FOR MID AND HNA ADDED
1326 Options to set the MID and HNA emission intervals and
1327 validity time in the configfile added.
1331 Option to set what IPv6 address type(scope) to use in the
1332 configfile added. It can be set to either global or site-local.
1336 Options to set site-local and global multicast addresses
1337 in the configfile added.
1339 EMISSION INTERVAL FUNCTION
1341 Functions to set emission intervals at runtime added.
1343 LINK LAYER NOTIFICATIONS
1345 If started with the -llinfo switch olsrd will collect and display
1346 link-layer information on neighbors. This is no longer limited to
1347 one interface. But no action is taken based on this info - and
1348 there is a upper limit of 8 neighbors from which this info can
1349 be collected pr. interface. This limitation is inherited from the
1350 WLAN drivers and is not something imposed by the olsrd code!
1352 IPv6 HNA MESSAGE FORMAT
1354 IPv6 HNA messages now contains 128-bit netmask instead of prefix.
1358 Added "packet transform functions" which allow plugins to alter all
1359 outgoing OLSR traffic.
1363 Moved most headers out of OS dependent directories. The tunneling
1364 and link-layer notification interface is not yet separated from
1365 the /linux directory.
1369 A manpage(olsrd(8)) describing olsrd has been created. It is installed
1370 when using 'make install'.
1373 0.4.3 ---------------------------------------------------------------------
1377 Olsrd now supports runtime-loadable plugins! A couple of example plugins
1378 are located in the lib/ directory. Read the README files in the various
1379 plugin directories for more info. A directive to load plugins have been
1380 added to the configfile as well.
1381 Documentation of the plugin interface can be fount at http://www.olsr.org.
1383 The plugin interface is designed to be extendable. But it should _always_
1384 be backwards compatible with the interface used in this release!
1386 LINK-LAYER NOTIFICATION
1388 Some preliminary link-layer notification code has been added. Link quality
1389 can be written to stdout if olsrd is started with the -llinfo switch.
1390 No action is currently taken based on this info. And info will only
1391 be retrieved from the interface named "eth1".
1392 This code is not usable for users as of yet!
1396 Neighbors with willingness set to WILL_ALWAYS is now always added. The
1397 MPR selection is optimized as described in RFC3626 section 8.3.1
1402 There was a couple of bugs in the MPR selection code. All fixed.
1406 Users could not run olsrd on multiple interfaces using the Linux 2.6 kernel
1407 series. This is now fixed.
1411 One small bug in link hysteresis initialization and one in HNA route
1414 MESSAGE-SEQUENCENUMBER INCOMPLIANCE
1416 Message-seqnos was implemented on a pr. messagetype and pr. interface
1417 basis. This is not RFC3626 compliant and has been updates. All messages
1418 and interfaces now uses a global seuencenumber.
1420 RANDOM SEQUENCENUMBERS
1422 Sequencenumbers are now initialized using a random value.
1426 Fixes for running olsrd in daemon mode(debug 0).
1430 Optimizations based on profiling implemented.
1434 Message size is checked for every message before passing it to the
1435 appropriate message parsing function. If the size is bigger than the
1436 remaining size of the olsr packet then the message is discarded.
1440 Some minor modifications done to the gui.
1444 Lots of changes in handling of registration and unregistration of
1445 scheduler, socketparser, parser and local hna set.
1446 Some restructuring and movement of functions.
1449 0.4.2 ---------------------------------------------------------------------
1453 0.4.1 ---------------------------------------------------------------------
1457 0.4.0 ---------------------------------------------------------------------
1461 Link hysteresis as described in the RFC added.
1465 TC redundancy as described in the RFC added
1469 MPR redundancy as described in the RFC added
1473 The scheduler has been rewritten to register scheduled
1474 events(function pointers) dynamically.
1478 The parser has been rewritten to register parse functions
1479 on a pr. messagetype dynamically
1483 A wrapper for the malloc(3) syscal has been introduced.
1484 olsr_malloc(size_t, const char *) should ALWAYS be used.
1488 Lots of restructuring in headerfiles.
1489 Linux spesific code moved to subdirectory linux/
1490 FreeBSD code to be put in freebsd/
1491 LOTS of code restructured due to the rexrite of the scheduler
1496 Optimizing the MPR set as suggested in the RFC section
1497 8.3.1 point 5 added.
1501 Some bugs in MPR selection fixed.
1504 0.3.8 ---------------------------------------------------------------------
1508 HNA code completely rewritten!
1509 The old code was really bad! Now it is much cleaner implemented and
1511 One- and two-hop neighbor list structures rewritten. They now use
1512 the same hashed double-linked lists as the rest of the information
1517 Some code restructuring which resulted in the new files: timer.h,
1518 mantissa.c, mantissa.h, hashing.c, hashing.h, linux/net.c
1519 linux/net.h, linux/kernel_routes.c, linux/kernel_routes.h and some
1524 The bug causing errormessages on exit is fixed.
1525 The bug that caused initial HNA routes in the GUI to display a hopcount
1527 IPv6 HNA netmasks were all added as /128. It's fixed now.
1531 Turns out sitelocal address had to be preferred to avoid IPv6 header
1532 messing up link-sensing. Bug fixed
1535 0.3.7 ---------------------------------------------------------------------
1539 The entire TC set and MPR selector set code rewritten. Hashing and
1540 double linked lists added to the MID code.
1541 Lots of HNA code has been rewritten as well.
1545 When a node lost connectivity to a HNA GW all HNA entries to that gw
1546 was deleted. This has been fixed - and HNA entries only gets deleted
1548 Other HNA bugs have been fixed as well. But the whole HNA implementation
1553 There was a bug that caused holdingtime not to be properly recalculated
1554 when using non-default emission intervals.
1556 Forwarding and symmetric neighbors
1558 Seems I had misread the RFC on what a 1-hop symmetric neighbor is.
1559 Now the link-set is checked when a check for a symmetric neighbor
1560 is done. Not the 1 hop neighbor set as it used to be. This way
1561 the hack when receiving MID messages could be removed.
1565 Global addresses are now preferred. Sitelocal addresses are only used
1566 if no global addresses are found. There have been problems where
1567 the address set in the IP header of IPv6 packets do not match the
1568 address chosen by OLSR.
1572 The GUI is finally updated! It can now handle piggybacked messages
1573 and link sensing HELLO message format.
1576 0.3.6 ---------------------------------------------------------------------
1578 HNA support using IPv6
1580 HNA now works using IPv6 as well! Just add the network address and
1581 prefix in the HNA6 section in the configfile. The IPv6 HNA packets differ
1582 some from the IPv4 as they don't send the netmask but the prefix.
1585 NEW FILENAME FOR THE BINARY AND CONFIG FILE
1587 They are now called olsrd and olsrd.conf. I figured I'd use the olsrd
1588 name before somebody else started using it ;-)
1593 New options: DEBUG, HNA6 and IPC-CONNECT added to config file.
1598 A printf-wrapper has been introduced - debug level output handling
1599 is much more uniform now.
1600 The daemon should run fine in detached mode now(DEBUG 0)
1604 The GUI front-end can now connect and disconnect at any time while the
1605 daemon is running, if started using the -ipc switch or with IPC set to
1606 'yes' in the configfile.
1611 A small HNA bug fixed.
1614 0.3.5 ---------------------------------------------------------------------
1618 Forwarding jitter added. Messages are piggybacked if they arrive(and are to
1619 be forwarded) while there is data to be forwarded buffered.
1620 Added some bugfixes to support parsing of piggybacked messages as well.
1624 Fixed route calculation so that 2 hop neighbors are added. This smooths
1625 changes from 1 hop to 2 hop neighbor out. The old way one had to wait for
1626 a TC before the 2 hop neighbors were added.
1630 All neighbors received in HELLO messages are added to the two hop
1631 neighborhood. This helps smoothing out the 1-to-2 hop transition as well.
1635 MID calculation had to be updated due to the registering of two hop neighbors
1636 that are already one hop neighbors. They should not be considered when calculating
1641 Deletion of possible one hop neighbors registered on non main-addresses when
1642 first registering MID info from a node removed. This can not occur due
1643 to the fact that registering of neighbor nodes are done on main addresses
1645 Option to not forward messages on wired links on which they arrived removed.
1646 This is no longer usable to any degree when adding support for piggybacking
1647 of forwarded messages is to be implemented.
1651 Some unused parameters and commandline options were removed.
1655 0.3.3 ---------------------------------------------------------------------
1659 Added sending of empty TC messages if all MPR selectors are removed. Empty
1660 TC messages are sent for a TC_HOLD_TIME period as described in section
1665 Fixed HNA route calculations for IPv6. I forgot to upgrade this in 0.3.2
1669 -hnaint and -midint command line optionas added to set the interval
1670 of HNA and MID generation.
1674 As an optimization messages have not been forwarded on the received interface
1675 if this is registered as a non-WLAN interface. This causes problems for
1676 people using Ethernet-to-WLAN adapters. This optimization is now turned
1677 off by default. It can be activated using the -nofwlan option.
1681 THERE ARE SOME NASTY BUGS IN 0.3.2!
1682 Fixed a bug that caused 2 hop neighbors not to time out.
1683 Fixed a bug that caused a 1 hop neighbor timeout not to recalculate
1685 Fixed a small memleak in the MID set
1686 Fixed some smaller bugs.
1688 IPv6 functioning is not well tested in this release.
1690 0.3.2 ---------------------------------------------------------------------
1694 Updated HNA to be RFC compliant. This means that all received HNA tuples
1695 are registered and only the subset of unique entries(net/netmask) with
1696 the smallest hopcount is inserted into the routing table.
1700 User can specify configfile name using the -f switch.
1704 Fixed a link-sensing bug that caused problems when using MID nodes.
1706 0.3.1 ---------------------------------------------------------------------
1710 MPR calculation is now based on the willingness announced by nodes.
1714 The neighbor set does not have timeouts on entries any more. Creation
1715 and deletion of neighbor entries is done from the link-set as suggested
1720 Gotten rid of a lot of code that became more or less obsolete due to
1721 all the changes introduced in 0.3.0.
1725 Fixed a nasty bug concerning the sequence numbering of TC packets.
1726 Fixed some bugs regarding MPR calculation - and probably introduced
1727 a whole new species when implementing the willingness-based calculation ;-)
1730 0.3.0 ---------------------------------------------------------------------
1732 Due to the extensive amount of updates this release is versioned 0.3.0
1734 Duplicate table and forwarding
1736 The duplicate table functionality is totally rewritten in 100% RFC
1737 compliance. The forward algorithm specified in the RFC is implemented
1738 this meant rewriting much of the packet processing code. The daemon
1739 also forwards unknown packettypes now.
1741 Link sensing and neighbor processing
1743 Link sensing and neighbor processing was done in the same operation in the
1744 old code. Link sensing is now a mechanism of its own which is 100% RFC
1745 compliant. Neighbor processing and HELLO generation has been partly
1746 rewritten to be RFC compliant. Neighbors are now registered as either
1747 SYN or NOT_SYM. The NOT_NEIGH, SYM_NEIGH and MPR_NEIGH values are only
1748 used when building HELLO messages. Links are in one of the following states:
1749 UNSPEC_LINK, ASYM_LINK or SYM_LINK.
1750 HELLO messages now advertise link status of neighbors on the interface
1751 the message is transmitted.
1755 A node now dynamically calculates willingness based on powersource and
1756 possibly battery power. If the node is AC powered it announces a willingness
1757 of 6. If batterypowered the willingness is calculated as:
1759 Where P is percentage of power left.
1763 The daemon now tries to read its configuration from the file /etc/uolsrd.conf
1764 A "standard" configuration file is installed when doing 'make install'.
1765 This file should be edited to fit your needs.
1766 Command-line options can still be used to override the configuration form
1767 the file(ore if no config file is present).
1768 The -f switch can also be used to specify a configuration file.
1772 If AdvancedPowerManagemant(APM) is supported on your system the willingness
1773 of the node is dynamically calculated based upon the powerstatus of the node.
1774 MPR calculation based upon willingness is not done as of yet.
1778 A bugs in the TC processing fixed.
1782 Some serious HNA bugs fixed. These bugs caused a node to always choos the
1783 gateway with the larges hopcout :) More seriously - a bug caused looping
1784 of HNA messages in certain scenarios.
1786 Package sequence numbers
1788 These were added. Not much use as of now - but they're there(as specified
1793 Users can now specify the broadcast address to use. Useful if one wishes to
1794 use the 255.255.255.255 broadcast.
1798 0.2.5 ---------------------------------------------------------------------
1802 Htime and Vtime processing and handling added. Holding times used to be
1803 a static value for all nodes. Now every node can signal its vlidity time
1805 To achieve this mantissa/exponent calculation functionality was added.
1806 Messages now include Vtime(and Htime in HELLO) values in mantissa/exponent
1807 format instead of just zero. These values are as stated above, used as holding
1809 the GUI should be upgraded as well...
1813 The use of jitter in message generation intervals vere fixed.
1816 0.2.4 ---------------------------------------------------------------------
1820 Some bugs concerning sequence numbers in HELLO and MID message handling
1821 was fixed. Newly registered nodes in the neighbor and MID sets were
1822 initialized with a seqno of 0. When using a "wraparound" sequencenumber
1823 check(as defined in olsr_protocol.h) this can produce errors if a new
1824 node joins a network where existing nodes has seqnos >0x00FF.
1828 Some checks and copying of node addresses where done using sizeof(u_olsr32_t)
1829 which is 32 bits. This caused only the 32 firs bits of IPv6 addresses to
1830 be copied and checked.
