127 - Replaced "which" with a /bin/sh script snippet
129 PATCHES and CLEANUPS by Bernd Petrovitsch <bernd@firmix.at>
130 - Jens Nachtigall <nachtigall@web.de> suggested (and reminded) to use
131 olsrd.conf.default.lq as the default installed one.
132 It makes much more sense as - to the best of my(bernd's) knowledge - all
133 larger networks uses the LQ extensions. And new customers should better
134 be pushed in that direction.
135 - with the help of Patrick McCarty <mccartyp@gmail.com>, we got olsr to build
137 * OpenBSD'd `sed` is pretty conservative and doesn't understand 's|re|sub|'.
138 So we fall back to the old 's/re/sub/' and quote all '/' and '.' correctly
139 (which was the main reason to use '|').
140 And while I'm at it: Remove the useless $(CCACHE) from the $(CC) for
141 dependency generation and beautify (read: "$(strip)") $(CPPFLAGS).
142 * OpenBSD needs an explicit "#include <sys/types.h>" before
143 "#include <netinet/in.h>".
144 - fixed lib/secure/src/md5.h: This was broken as it had
145 "typedef unsigned long int UINT4;". "unsigned long int" is 8 bytes on x86_64.
146 We are using now the standardized types from <inttypes.h>.
147 - fixed warnings and improved lib/secure/src/md5.c:
148 * we are using memcpy() and memset() instead of the open-coded loops as
151 * added function prototypes for static functions
152 * moved static functions to the top so that their declaration is before
153 their use to allow gcc to inline if only used once.
154 It remains ugly - God knows why there are that so many useless
156 - Some minor and trivial cleanup: Added two functions to calculate the ETX
157 value from a struct tc_edge_entry and a struct link_entry, respectively.
158 And use them everywhere.
159 - added http://meshcube.org/nylon/utils/olsr-topology-view.pl into
160 lib/httpinfo/misc as suggested by Jens Nachtigall <nachtigall@web.de>
161 - Killed "struct olsrd_config *cnf" in src/cfgparser/olsrd_conf.h and replaced
162 it's usage with "olsr_cnf" from src/defs.h.
163 Serious cleanup: olsrd_get_default_cnf() does no longer initialize the global
164 "cnf" variable" but uses a local one which is returned as before. And
165 olsrd_parse_cnf() does no longer return the global variable it is working on.
166 - Merged "struct hna4_entry" and "struct hna6_entry" into
167 "struct local_hna_entry" (as "struct hna_entry" is a different thing)
168 Both have almost the same data (IP address + netmask/prefix) so we use
169 the quite new "struct olsr_ip_prefix" to store it.
170 Also merged the "hna4" and "hna6" pointer in "struct olsr_config" -
171 look at the global "olsr_cnf->ip_version".
172 - added a olsr_ip_prefix_to_string() function
173 - .h file cleanup: def.h does not longer include net_olsr.h because it
175 - more type safety: the macros COPY_IP() and COMP_IP are gone and replaced
176 with "=" or similar "normal" C operations. There are also now the inline
177 functions ip4cmp() and ip4equal() to work on "struct in_addr", ip6cmp()
178 and ip6equal() to work on "struct in6_addr" and ipcmp() and ip6equal()
179 to work on "union olsr_ip_addr".
180 Most (or even more precise: almost all) uses of COPY_IP() and COMP_IP()
181 are in "if (olsr_cnf->ip_version) { ... } else { ... }" anyway to
182 there is no reson to copy an IPv4 address effectively with
183 "memcpy(&dst, &src, 4)" or compare with memcmp(&a, &b, 4)" wher the
184 always "4" is stored in a variable inhibiting compiler optimization.
185 There is also the deprecated function genipcopy() mimicking the old
186 typeless COPY_IP() macro for the last few places where a cleanup is
188 There also lots of old macros left over (commented out of course) until
189 we are confident that everything works. And then I will kill them too.
190 - Fixed the misleading definition of "v4" in "struct olsr_ip_addr" fom
191 "olsr_u32_t" (in network-byteorder!) to "struct in_addr". Lots of
192 temporary variables to call inet_ntoa()/inet_ptoa() vanished .....
193 - We have now ip4_to_string(), ip6_to_string() and olsr_ip_to_string()
194 to print a "struct in_addr", "struct in6_addr" and "union olsr_ip_addr"
195 into a string buffer.
196 - cleanup: olsr_ip_to_string() and similar non-reentrant functions now must
197 get a target buffer. To ease that, there is the "struct ipaddr_str"
198 which is large enough for all of them (read: for an IPv6 address). This
199 also removes the cyclic buffer there.
200 All of these function return a "const char *" which can be directly used
201 for printf(3) and friends.
202 - const'ified more functions
203 - converted the source to UTF-8.
204 - "struct sig_msg" uses an olsr_u8_t for a byte array (and not "char")
205 - force the few inline function to always be inlined.
206 - #ifdef the body of the olsr_print_hna_set() and olsr_print_neighbor_table()
208 - declare "int_addr", "int_netmask" and "int_broadaddr" in "struct interface"
209 as "struct sockaddr_in" since it is that what we actually want there (and
210 it is similar to the IPv6 code).
211 - updated the olsrd.conf.default.lq-fisheye to the Debian-deliverd version
212 after recent discussions olsr-dev@olsr.org
213 - use "inline_avl_comp_ipv4()" in "avl_comp_ipv4()"
214 - clean up the routes on more signals. Basically we want to do this on all
215 signals which terminate the program.
216 - killed a superflous global buffer in src/main.c
217 - made inline functions from avl_walk_{first,last,next,prev} and created
218 "const" versions of it. inline_avl_comp_ipv4() is now also an inline function
220 - created a typedef's for various function pointers - much easier to read.
221 - cleanup: compare tree->comp (adn other pointers)) to NULL (and not 0)
222 - killed superflous "return"s at the end of void functions
223 - const'ified more parameters in many more functions in the .h and
225 - init-functions with constant or ignored return values are "void"
226 - created a typedef fro the callback in "struct export_route_entry"
228 - moved the initialization of the {add,chg,del}_kernel_list variables
229 into process_routes.c. So they are now "static" there.
230 - olsr_export_{add,del}_route{,6} are now static in process_routes.c
231 since they are not used elsewhere.
232 - olsr_addroute_add_function() and olsr_deldroute_add_function() were
233 almost identical - made one function out of it.
234 Same for olsr_addroute_del_function() and olsr_deldroute_del_function().
235 - fixed the sort order in avl_comp_ipv4_prefix(): We compare now the IPv4
236 values in host byte order (and not network byte order). So the route
237 list in the e.g. httpinfo plugin is now nicely sorted.
238 - fixed and improved the `gcc-warnings` script:
239 * support older gcc's (as on Debian/Sarge) as they have slightly different
241 * removed superflous lines
242 * replaced the call of `sed` with shell built-in features fixing syntax
243 errors on Debian/Sarge
244 * set all locale-relevant variables to "C" (just to be sure)
245 - consolidated ip{4,6,}{cmp,equal}: all are nwo inline functions using only
246 the minimal necessary operations. Thanks to Hannes Gredler
247 <hannes@gedler.at> and Sven-Ola Tuecke <mail2news@commando.de> for pointing
248 that out and suggesting the `inline`, respectively.
249 use ip{4,}cmp in lq_avl.[ch] to resue the code. inline_avl_comp_ipv4
250 is superflous now (and replaced by ip4cmp) and use the global MIN and MAX
251 macro instead of AVLMIN and AVLMAX
252 - killed netmasks from the IPv4 part of the code and use the prefixlen there
253 (similar to thte IPv6 part). Manymore details on
254 http://lists.olsr.org/pipermail/olsr-dev/2007-November/001464.html
255 - removed the superflous "open_ipc" field from the "struct olsrd_config" as
256 it contains only the equivalent of "olsr_cnf->debug_level > 1".
257 - inspired by Sven-Ola Tuecke: avoid a bash'ism (i.e. "OPTS="${OPTS//$opt}") in
258 gcc-warnings and ld-warnings. But we do not replace it with `sed` (since it
259 costs a fork(2) and an exec(3)) but also with shell code which doesn't use
260 any external program.
261 - added configuration file support for "flat fib metrics".
263 0.5.4 ---------------------------------------------------------------------
265 QUAGGA by Immo 'FaUl' Wehrenberg <immo.olsr@do.bundessicherheitsministerium.de>
266 - updated to svn version 33
268 BMF PLUGIN by Erik Tromp <erik_tromp@hotmail.com>
270 - updated to latest plugin interfaces changes and killed warnings (by Bernd
271 Petrovitsch <bernd@firmix.at>)
273 PATCH by Hannes Gredler <hannes@gredler.at> which rewrites the route handling.
277 - get rid of separate routing tables for HNA and per-node routes, everything is
278 now unified in an AVL routing tree (&routingtree)
280 - introduce walking macros (OLSR_FOR_ALL_RT_ENTRIES()) that hide the internal
281 structure of the RIB for making life of the plugin authors easier.
283 - get rid of different SPF implementations for LQ and non-LQ code paths. a
284 non-LQ edge is simply substituted with a cost of 1.0
286 - get rid of host masks - a new data type olsr_prefix is introduced which is
287 basically an ip address plus a prefix length.
289 do not install the metric in the kernel FIB - for the kernel its pointless
290 if the route gets installed with a metric of N or M.
292 we do not need to update the kernel FIB if we have hop count only changes
293 (for example if there is a reroute action further downstream)
295 the only things which triggers a kernel FIB route update is a next hop
296 change (a next hop is neighboring gateway router plus an interface).
298 all OLSR routes are installed with a metric of 2
300 - separate between rt_entry and rt_path - the former is a route installed in the
301 kernel with an next hop. the latter is a candidate for best path selection
302 after SPF calculation has been done. in the rt_entry we keep a pointer to the
303 best_path and also to the next hop that was installed in the kernel FIB.
305 we always keep all originator of a route, if a route originator goes away we
306 can easy recompute the best path for the route.
308 the next hop in the rt_entry gets only updated upon a successful route_add
309 call - that way we always remember what next hop to delete.
311 stray routes should be history now.
313 - tweak the linked list toolkit to operate on circular lists.
315 - get rid of malloc calls for building the kernel update list. the list node is
316 now embedded in the rt_entry.
318 - introduce three queues (add/chg/del) for kernel updates.
320 - for neighbor route dependency tracking the neighbor routes are queued first or
321 last (depending on which queue you work on)
323 - rework all the plugins which directly manipulate rt entries.
325 - rework the plugins that read from the routing table (most notably nameserver,
326 httpinfo and quagga plugin)
328 - lots of comments that explains the intentions and purpose of this code-piece.
330 non RT related stuff:
331 - use a list rather than a tree for storing the post-SPF results, which further
332 improves the raw-SPF runtime.
334 - add display of SPF runtime (masked behind #ifdef SPF_PROFILING)
336 - http://gredler.at/download/olsrd/neighbor_routes3.diff: This updates the own
337 IP address (read: the main address) after changes (e.g. on
338 `ifup wlan0; sleep 1; ifdown wlan0`) and kills the
339 olsr_fill_routing_table_with_neighbors() function.
341 And Sven-Ola Tuecke <mail2news@commando.de> fixed an instability issue on interface
342 up/down operations (see 102-olsrd-rt-refactoring-fixes.patch below) and a missing
345 PATCH by Hannes Gredler <hannes@gredler.at> which "consolidates
346 the link-state database and the spf-calculation in order
347 to calculate routes more efficiently".
350 - use the link-state (tc) database for SPF calculations rather than
351 replicating the notion of vertices and edges for a SPF run.
352 this heavily reduces malloc() calls and shrinks the total CPU
353 load of the route calculation path between 60%-80%.
356 PATCHES by Sven-Ola Tuecke <mail2news@commando.de> to be found on from
357 http://download-master.berlin.freifunk.net/sven-ola/nylon/packages/olsrd/files/
358 - 102-olsrd-rt-refactoring-fixes.patch
359 Because you changed a lot of basics: It's time to handle a general
360 flaw in the routing system. Plase take a look at chk_if_changed(). This
361 will free() any "struct interface" pointer without warning at any time.
362 This is why it's possile to SEGV olsrd with a simple "ifdown xxx".
363 The patch replaces the (maybe) invalid pointer with an index reference
364 "iif_index". You can always ask the OS for a name. Please note, that I do
365 not have a working BSD toolchain, so I've placed an #error in the IPv6
366 BSD-part where the author/porter has started to hack something funny.
368 - 110-olsrd-double-wlancard-neigh-hack.patch:
369 This is a hack for Nodes having to wifi cards with the same channel,
370 bssid, IP-Range etc. If two nodes can see each other by means of two
371 possible links (here: two wifi cards with equal config), a bug is triggered
372 with the Neigh-is-SYM detections. This small little hack prevents this.
374 - 112-olsrd-nameservice-fixemptyname.patch:
375 This is an addon to my lat/lon stuff which will prevent olsrd from
376 running (oops?) if no hostname is given and the nameservice plugin
379 - 113-olsrd-dyngwplain-pluginvers5.patch:
380 This updates the dyngwplain plugin to the new Plugin Iface
382 - 140-olsrd-arprefreshed.patch:
383 This is a new one. Opens a packet socket and listen to UDP(698), extract
384 the sender MAC and refreshes the ARP cache whith that. Should speedup
385 especially in cases, if you initially try to use a longer routing path which
386 normally triggers a "ARP-Lookup-Chain".
387 - 106-olsrd-nameserviceparams.patch:
388 This patch converts more plugins to the new interface version.
389 - 104-olsrd-policy-routing.patch
390 Reworked this one to discard GPL helper functions. Also checked IPv6 and
391 re-included the IPC hookup. The patch adds a "RtTable [number]" for
392 /etc/olsrd.conf which is simply the Linux
393 policy routing table to use. Defaults to 254 (== main).
394 This patch was modified/clenaed up by <bernd@firmix.at> to use "#if"
395 instead of "#ifdef" as it's more robust against typos.
396 - 110-olsrd-fixpacketprint.patch, 112-olsrd-nameservice-fixemptyname.patch,
397 113-olsrd-txtinfo-fixhttpget.patch, 114-olsrd-timeoutlimit.patch,
398 115-olsrd-nameserviceparamfix.patch and
399 116-olsrd-fix-pluginparam-addons.patch fixing the compilation warning
400 on 64bit and lots of other improvements.
401 - "Save the fish" patch: Avoid forwarding of packets with too low TTL. This
402 kills lots of packet forwarding storms.
403 NB: The oneliner was applied by hand by BP and formatted to look (in BPs O)
406 PATCH by Arnd Hannemann <hannemann@i4.informatik.rwth-aachen.de>
407 olsr_makefile_make_use_of_exename.patch
408 - This patch makes sure that the EXENAME variable of Makefile.inc is used
411 PATCHES by John Hay <jhay@meraka.org.za>
412 - update to new FreeBSD WLAN API
413 - do not require /bin/bash, use /bin/sh
414 - Fixed alignment so that olsrd runs on FreeBSD/arm
415 - allow more interface in an IPv6 subnet on FreeBSD
416 - use PREFIX and DESTDIR as all the other Makefile.$OS also for FreeBSD
417 - make txtinfo plugin work with IPv6
419 PATCH by Andreas Jacobs <jacobs@i4.informatik.rwth-aachen.de>
420 - fix the loss link quality calculation for "windows size % 4 != 0"
422 PATCH by Acinonyx <acinonyxs@yahoo.gr>
423 - Bug fix: include $(TOPDIR)/Makefile.inc at the begin in the Quagga plugin
425 PATCH by David Cornejo <dcornejo@gmail.com>
426 - fixed an "+=" of an uninitialized variable (detected with/by the
429 BUG reported by Aaron Kaplan <aaron@lo-res.org>
430 - BSD-xargs doesn't know "-r".
432 PATCHES and CLEANUPS by Bernd Petrovitsch <bernd@firmix.at>
433 - Made a function from the ME_TO_DOUBLE() macro (in src/mantissa.h).
434 This saves code throughout the code even on i386 and will even more
435 on architectures without floating point units and "-msoft-float".
436 - And the mathemathics in src/mantissa.h is reformulated to minimize
437 floating point operations to save CPU power - especially on embedded
439 - I rewrote the half of src/lq_packet.[ch] which deals with incoming
440 packets. This was triggered with performance output of gcc produced
441 by Sven-Ola Tuecke at CCCamp07.
442 This kills *lots* of (more than) superflous malloc()s and the same
443 number of (free()s). And it also kills some code and copying around of
445 - Make it compile without warning with flex-2.5.33 (to be found on Fedora 7
446 and Gentoo in Sep-2007) again.
448 - converted the dyn_gw plugin to plugin interface version 5 (which leaves
449 the quagga plugion as the last with the old one).
450 - paving the way to activate -Wshadow, much more to do
451 - const-ify parameters here and there
452 - use NULL for pointers (and not "0")
453 - Killed "extern" declarations in (not generated) .c files
455 - Based on a patch by Gianni Costanzi <gianni.costanzi@gmail.com> (so credits
456 and thanks have to go there):
457 added OS_CFLAG_PTHREAD Makefile variable since gcc (on Linux) requests this
460 - I added definitions to all OS-specific Makefile.$OS with the value similar
461 to the value in OS_LIB_PTHREAD (either empty or "-pthread").
462 - The variable is added to CPPFLAGS (and not CFLAGS) since CPPFLAGS is used
463 for all cpp and gcc calls (and gcc's man page indicates that it sets
464 variables for both of them).
466 0.5.3 ---------------------------------------------------------------------
469 Ignacio GarcÃa Pérez <iggarpe@terra.es> found a serious bug in the dot-draw
470 plugin and identified it's source.
473 The bmf plugin wanted to kill a not-started thread and this causes a segmentation
474 violation. This happens if the old plugin interface support is not compiled in
475 and one uses - or more asccurate: wants to use - the bmf plugin which uses that
476 ATM. Thanks to Cedric Krier <ced@ced.homedns.org> for reporting this.
479 The dependencies (*.d files) are now properly generated and used. And they also
480 dependen on the Makefile in the current directory and the Makefile.inc so that
481 changes there also lead to new compilation.
482 Remember: We support "ccache" so install it to save lot of meaningless recompiles
483 if nothing (as seen by the real C compiler, i.e. after the C preprocessor) has
487 Linux/IA64 and Linux/HPPA also need "-fPIC".
490 - olsr_switch does no longer generate warnings
491 - olsr_switch is also built with "build_all" and cleaned with "uberclean"
492 - More "const" all over the place.
493 - More "static" for local functions and variables.
494 - Killed an unnecessary "static" variable.
496 0.5.2 ---------------------------------------------------------------------
499 Sven-Ola Tuecke found a serious bug of the class "show stopper" and sent a patch.
502 Plugins handle parameters quite individually (case-sensitive vs case-insensitive,
503 different parsing functions for the same values, etc.). Plugin Interface version 5
504 now exports a table of { parameter-name, parsing-function, addr-of-storage } and
505 it's size. Common functions should be shared.
507 0.5.1 ---------------------------------------------------------------------
510 Upgrade to olsr-bmf 1.5 from Erik Tromp <erik_tromp@hotmail.com>
512 latitude/longitude support is now in the nameservice plugin done by
513 Sven-Ola Tuecke <mail2news@commando.de>
515 added the spf refactoring patch from Hannes Gredler <hannes@gredler.at> which
516 saves a noteworthy amount of CPU time. To quote him:
518 1. use of an AVL tree as a min-heap implementation
520 as a means for efficient sorting.
521 (the etx metric is used as the key in the candidate tree)
523 2. next-hop propagation
525 rather than tracking the previous node in olsr_relax()
526 i have changed that model and pre-populate all one-hop neighbors
527 with their own IP adress as 'next-hop' and pull that
528 pointer up once new paths are explored.
530 as a result no walker for counting hops and extracting next-hops
531 is required - it turns out at this is slighly more efficient
532 than the existing behaviour (even with the cache applied).
536 * moved a only locally needed hack from "union olsr_ip_addr" into the only place
537 where it is needed in hashing.c
539 0.5.0 ---------------------------------------------------------------------
541 APPLIED PATCHES FROM FREIFUNK-FIRMWARE
542 libsmake, dyngwplain, nameservices+services, tzxtinfo, quagga, quagga-routehandler,
543 optimize, fixes from Eric Tromp and Sven-Ola Tuecke, CPU-optimize, secure key, HNA-IP
546 removed hardcoded limit on the number of interfaces (at least in the Unix part)
547 made Makefile targets much more consistent
550 put Bmf-1.3 plugin into it
554 Patch from John Hay applied.
558 0.4.10 --------------------------------------------------------------------
560 OLSR NETWORK SIMULATOR
562 An application called olsr_switch(sorry for the nameclash with the win32
563 GUI) has been added. If olsrd is ran using the -hint option it can now
564 connect to olsr_switch and be part of a virtual network. This means
565 that multiple instances can be ran at the same host! The olsr_switch
566 application allows the user to define link variables on all viritual
567 links in the network, creating all possible topologies. Read more in
570 EXPERIMENTAL FISH EYE ALGORITHM
572 An experimental algorithm for TTL settings on TC messages has
573 been added. Read more in the corresponding README file.
577 olsrd now also compiles on OpenBSD systems. Thanks a lot to Holger
578 Mauermann for the patches!
582 Bruno has rewritten the make system. OS detection is now done
583 automagically and the general design is much improved.
585 IP ADDRESS VALIDATION
587 Olsrd now maintains a set of IP addresses that is considered
588 invalid. Checks against this set is done on all received
589 OLSR packets announced originator addresses. The dataset can
590 be updated dynamically.
594 Updated interface version to 3 and added more noticeable warning
595 for version missmatch.
599 The dependency on the math lib came from the use of pow(3) in the
600 mantissa/exponent calculation. The calls to pow in this long forgotten
601 code, was very unnessecarry. The pow calls are replaced with bitwise
602 shifts and -lm is no longer needed.
604 ICMP REDIRECTS ON LINUX
606 On Linux systems "0" is now also written to the all/send_redirects
607 procfile and not only the pr. interface ones. Hopefully this resolves
608 problems reported with systems still sending ICMP redirects.
612 - Fixed init of IPv6 addrtype variable. It used to be uninitialized,
613 causing it to default to site-local and have some weird side-effects.
614 - Fixed crash when changing IPv6 address at run-time
615 - Fixed a bug that prevented setting willingness 0 in the configfile
616 - Fixed bad handling of missing command line arguments
617 - Did various updates to prevent assertion when a neighbor
618 has changed IP and sends HELLO before its olsrd precess has detected
620 - Fixed return value check on times(2) calls in the scheduler
621 - Fixed bug(s) that could cause crash when an interface was brought
622 down while olsrd was running.
623 - Removed the silent (read: unchecked) hard limit of 16 interfaces.
624 - Compiles now cleanly on 64bit (e.g. x86_64).
626 0.4.9 ---------------------------------------------------------------------
630 The MID database is now also indexed by alias addresses. this makes
631 look-ups of main addresses based on alias addresses _much_ faster.
632 The mid_lookup_main_addr function alone has gone from >30% of the
633 total CPU time used by olsrd to <1%.
634 PLUGIN DEVELOPERS: datatypes for MID entries has been changed.
636 Routing table calculation in the LQ case now uses balanced binary
637 trees instead of linked lists, which makes look-ups much faster.
639 The debug output function olsr_printf() is not used by olsrd
640 internals any more. Instead the macro OLSR_PRINTF is to be used.
641 This macro does debug level testing _before_ doing any function
642 calls(both printf itself and parameters to printf). This is a much
643 more optimized way of doing debug output. In addition olsrd can
644 be built without any debug output code if doing 'make NODEBUG=1'.
648 Validity times for dataset entries are now set using the clock_t type
649 (used to be struct timeval). This data is now fetched from the times(2)
650 function instead of gettimeofday(2). This prevents possible problems
651 if the system time is changed.
652 PLUGIN DEVELOPERS: Note that datatypes for close to all dataset entries
653 (link, neighbor, mid, hna, tc etc.) has been changed!!
657 Multiple interfaces can now use the same interface configuration block.
659 Interface "if0" "if1" "if2"
664 Interface configurations now also support the "Weight" directive. When
665 olsrd finds multiple links to a neighbor it will choose the link
666 going via the interface with the lowest weight. Olsrd normally
667 sets this weight dynamically based on interface characteristics,
668 but if the user wishes to set a fixed weight in a interface(or
669 a group of interfaces), this directive is now available.
671 Moreover, interface configurations now support the "LinkQualityMult"
672 directive. It takes an IP address and a multiplier as arguments.
680 LinkQualityMult 192.168.0.1 0.7
681 LinkQualityMult default 0.5
686 The idea is to make certain links via the configured interface
687 artificially worse or better than they really are. The first parameter
688 specifies the IP address of a neighbour interface. The second
689 parameter is the multiplier to be applied to the link to the specified
692 After we have derived the link quality from the packet loss among the
693 packets received from the specified neighbour interface, we multiply
694 the link quality by the given multiplier. So, the multiplier changes
695 the LQ value that we use when determining the ETX, which is 1 / (LQ *
698 If "default" is given as the IP address then the multiplier applies to
699 all links via the configured interface. Note, however, that olsrd only
700 assigns one multiplier to each link. It does so in the following way.
702 * If there is a "LinkQualityMult" line that matches the IP address of
703 the link's neighbour interface, then use the multiplier in this
706 * If there isn't any matching line, then look for a "default" line. If
707 there is a "default" line, then use the multiplier in this "default"
710 * Otherwise use 1.0, i.e. do not modify the LQ value at all.
712 Hence, a line with an IP address has priority over a "default" line.
714 In the above example, the LQ value of the link between the local
715 interface if0 and the neighbour interface 192.168.0.1 would be
716 multiplied by 0.7. All other links between the local interface if0 and
717 a neighbour interface would be multiplied by 0.5.
721 The socket option IPV6_V6ONLY is now set on IPv6 sockets in linux.
722 This means that olsrd will no longer receive IPv4 traffic when
723 running in IPv6 mode.
724 This should enable users to actually run one olsrd instance using
725 IPv6 and one using IPv4 at the same time :)
729 The httpinfo, dyn_gw and dot_draw plugins now all include olsrd
730 headerfiles directly. A plugin should define OLSR_PLUGIN before
731 including olsrd headers. Doing things this way removed the
732 redundant datatype definitions that has so often caused trouble
733 when things has been updated in olsrd.
737 olsrd now also compiles on NetBSD systems. Use 'make OS=nbsd' to
738 build. This port is not very well tested and feedback is greatly
741 EXPERIMENTAL MULTI-INTERFACE CODE FOR FREEBSD
743 Experimental code using libnet can be compiled in allowing multiple
744 interfaces to be used in FreeBSD. You enable this by compiling using
745 OS=fbsd-ll. You must have libnet-devel installed for this to work
746 (/usr/ports/net/libnet-devel).
750 - WLAN devices are now detected in FreeBSD
751 - First specified interfaces IP is used as main address.
752 - Broadcastflag is not checked on interface if fixed broadcast is
754 - Removed Linux link layer code as this was not really in use.
755 - Added -nofork command line option
759 - Link sensing now works according to announced vtime from
760 neighbors. Previously links going symmetric->asymmetric
761 were not necessarily detected until the holding time expired.
762 - A bug in route addition/removal that could lead to routes
763 using GWs being added before the actual route to the GW
764 was set up, has been fixed.
765 - A bug in the interface selection in route calculation has been
766 fixed. New routes are no longer added prior to deleting old ones,
767 since this caused trouble.
768 - A bug in the IPv6 multicast address configuration has been fixed.
769 This caused olsrd not to work with global IPv6 addresses.
770 - A bug in the IPv6 prefix-from IPaddr function has been fixed. This
771 bug caused HNA prefixes to always be calculated to 0.
772 - If a 2-hop neighbor is also a 1-hop neighbor, a bug made olsrd
773 prefer a bad direct link to a better link via an MPR.
774 - If a link or interface lookup failed, olsrd crashed.
775 - Fixed a crash in the LQ packet generation code based on a
776 signed/unsigned integer comparison.
779 0.4.8 ---------------------------------------------------------------------
783 Olsrd is now distributed under a BSD style license. We believe olsrd will
784 be better off using this license as it opens up for commercial players
785 to use olsrd freely in their products. In the end this will lead to
786 this kind of users doing serious testing and bug fixing of olsrd.
788 ETX-LIKE LINK QUALITY DETECTION
790 We can now determine the packet loss on a link by looking at the serial
791 numbers of the OLSR messages received from a neighbor. This tells us how
792 many packets get through from our neighbor to us. We use a new extended
793 kind of HELLO messages (LQ_HELLO messages, LQ = link quality) to broadcast
794 the link quality that we have determined on our end of the link to our
795 neighbors. So do our neighbors, and we as well as they end up with an
796 idea of how good the link is in both directions. From the LQ_HELLOs we
797 also learn the link quality between our neighbors and our two-hop neigh-
798 bors. In this way we can select those neighbors as MPRs that have the
799 best links to our two-hop neighbors. To distribute the link quality
800 throughout the network, we use a new extended version of TC messages
801 (LQ_TC messages). They contain the qualities at both ends of each of our
802 links. Nodes can then run Dijkstra's algorithm to find a path between
803 themselves and other nodes that minimizes the packet loss.
805 If the newly introduced "LinkQualityLevel" is set to zero in the
806 configuration file, link quality is not used and the daemon behaves as
807 before, i.e. as specified by the OLSR RFC. If this parameter is set
808 to 1, LQ_HELLOs and LQ_TCs are used instead of HELLOs and TCs, link
809 quality is measured and MPRs are selected based on the link qualities.
810 If this parameter is set to 2, the routing table is additionally
811 calculated based on the link qualities.
813 Setting "LinkQualityLevel" to a non-zero value BREAKS COMPATIBILITY. You
814 will then not be able to participate in RFC-conformant OLSR networks
815 any longer. This is because we use LQ_HELLOs and LQ_TCs instead of HELLOs
816 and TCs in this case.
818 It's best practice to set "LinkQualityLevel" to the same value on all
821 When determining the quality of a link olsrd only considers a given
822 number of most recent OLSR packets received from its neighbors. By
823 default, olsrd looks at the 10 most recent OLSR packets. This can be
824 changed via the "LinkQualityWinSize" configuration option. Values
825 between 3 and 128 are legal.
827 NEW CONFIGFILE PARSER/FORMAT/SCHEME
829 A whole new config file syntax and parser is introduced with this
830 release. The parser is generated using flex and bison and it is
831 designed to be very modular. The parser can be compiled as either
832 a standalone binary, a shared library or as part of olsrd. This way
833 other applications can parse and generate olsrd configuration files
834 only by linking to the dynamic library.
835 In the new configfile options can be set pr. interface, plugin
836 parameters can be set, more IPC options can be set...and more.
837 The syntax is documented in the olsrd.conf(5) manual page found
838 in the files/ directory.
839 Olsrd internals now uses a single struct, as returned by the config
840 parser, for all configuration in runtime. this means that updating
841 values in this struct will dynamically update olsrd operation. It
842 also means that all configuration is now kept in one place instead
843 of spread all across the place.
845 FREEBSD AND MAC OSX PORT
847 This version offers an initial port of olsrd to FreeBSD and Mac OS
848 X. Like the Windows port it currently does not support IPv6. As this
849 is a very first try at supporting FreeBSD and Mac OS X, this port is
850 probably not as reliable as the Linux version. We'd greatly appreciate
851 feedback and bug reports. To compile you need GNU make. Then simply
852 run "gmake OS=fbsd" to build the executable.
856 The makefiles used to build olsrd have been rewritten and now includes
857 dependency file generation using makedep.
861 Tables are now only printed if changes occur, so there are no longer
862 any periodical output when using a debuglevel >0. A "heartbeat" is
863 now printed to STDOUT(if it is a terminal) in the form of a rotating
864 line to show that olsrd is actually operating.
865 Adding "ClearScreen yes" to the configuration file clears the screen
866 each time before the debug output shows updated information. This
867 makes the debug output easier to read in many cases. "ClearScreen no"
868 is the default, if no "ClearScreen" directive is given in the
873 There are some changes in the plugin interface. It is now at
874 version 2. Plugin specific parameters from the configfile
875 using the PlParam option, will now be passed on to plugins.
876 To receive such parameters a plugin must implement a function:
878 register_olsr_param(char *key, char *value)
879 to which parameter pairs will be passed.
883 Olsrd no longer uses any thread library on its operation. Everything
884 now happens in the main thread allowing for use of olsrd on platforms
885 with no thread library.
887 ACPI SUPPORT IN WILLINGNESS CALCULATION(LINUX)
889 The willingness calculation for Linux, now also supports the more
890 modern ACPI proc interface in addition to APM. This is not well
891 tested and feedback is appreciated!
895 Various options regarding IPC connections can now be set in the
896 configfile. The options are max connections, allowed unicast
897 hosts and allowed net-ranges.
901 Much of the message generation and net output code is rewritten.
902 Sending of partial messages should now work 100%. Also TC, MID
903 and HNA messages are now cached for a random amount of time
904 before transmitted - this often leads to the situation where these
905 messages are sent together with an HELLO message, which is highly
906 desirable since it saves network resources.
907 PLUGIN DEVELOPERS must note that the buffers and size variables
908 used in net output is no longer directly accessible!
910 NET OUTPUT CODE REWRITTEN
912 Every interface now has one outputbuffer registered. This allows
913 messages to be "cached" as explained above, so that multiple
914 messages are stacked together.
915 Also the outputbuffer and size are no longer accessible directly,
916 an API is available to plugins(and olsr code).
918 OS DEPENDENT NETWORK INTERFACE
920 The OS dependent network functions are now defined in net_os.h
921 instead of being mixed up with internal network functions
926 A bug that caused the announced ANSN sequence number to never stop
927 being increased when a change in the MPR selector set was detected
928 has been fixed. Another TC related bug that caused timed out TC
929 entries not to be deleted from the routing table in certain cases
930 has also been fixed. These bugs could cause unstable routes.
931 A bug that in many cases caused the wrong routes to be deleted
932 when using IPv6 has been fixed.
935 0.4.7 ---------------------------------------------------------------------
937 NATIVE WINDOWS GUI AND INSTALLER
939 We now have a native Windows GUI. The GTK+ version is no longer
940 supported on Windows. The new native GUI is pretty compact as it does
941 not require the GTK+ runtime DLLs. In addition to monitoring olsrds
942 state the GUI offers an easy way for novice users to configure
943 olsrd. It's pretty self-explanatory. Have a look at README-WIN32.txt
944 for details. The Windows version now also comes with an installer
945 based on the freely available Nullsoft Scriptable Install System
946 (NSIS). Looks like the Windows port is becoming more and more
949 WIRELESS INTERFACE DETECTION ON WINDOWS
951 Like the Linux version the Windows port is now able to tell WLAN
952 interfaces from wired interfaces. We can now, for example, set
953 different HELLO intervals for WLAN interfaces and wired interfaces,
958 The order of updates of calculated routes is swapped. Now new routes
959 are added prior to deleting old ones. This could fix issues where
960 in some very very few cases one could experiment loss of routes.
964 There were quite some bugs in IPv6 operation in 0.4.6. These are
965 the bugs that were fixed:
966 - HNA message parsing did not work.
967 - Some IPv6 addresses were printed as IPv4 addresses in the
969 - The '-dispin' option now works again.
970 - A filedescriptor leak in the IPv6 interface detection caused
974 0.4.6 ---------------------------------------------------------------------
978 Read the README-WIN32.txt file!
980 DYNAMIC NETWORK INTERFACE UPDATES
982 Network interfaces can now be updated and removed/added at
983 runtime. Olsrd will check all interfaces specified in the config
984 file or on the command-line, every 5 seconds. If updates
985 occur, olsrd will register this and update the necessary data.
986 If interfaces are removed or added, olsrd will detect this
987 and configure the interfaces. If an interface is removed
988 olsrd will continue to check the interface, so if say, a PCMCIA
989 card is removed and later on reinserted(and given the same name),
990 olsrd will detect this and start running on it again.
992 Note that olsrd will now run even if no interfaces are detected.
994 ROUTE CALCULATION UPDATE
996 All 1 hop neighbor addresses that are not directly reachable trough
997 a symmetric link in the link set will now be added with a GW in the
998 routing table. this GW will be an interface address from a registered
999 symmetric link to the neighbor.
1003 Alias addresses are now registered in the link set processing
1004 if available. This is not to pretty(since the vtime has to
1005 be a mere guess) but it gives faster initial route updates.
1006 If a HELLO is received(at initial registration) from an IP
1007 that is not the same as the one set as main address in the
1008 received HELLO header, then the IP from which the HELLO was
1009 received will be registered as an alias of the main address
1010 set in the HELLO header. The default vtime is set to 15 secs.
1014 All OS dependent interface configuration code is now located in
1015 OS/ifnet.c(that would be linux/ifnet.c if using GNU/Linux).
1016 The functions are available trough the headerfile src/ifnet.h
1020 - Some timer issues fixed
1021 - Got rid of the global socket descriptors
1022 - Updated indexing of network interfaces
1023 - Introduced a global socket to use for ioctl calls(ioctl_s)
1024 - Removed upper limit for interfaces to use
1025 - Point-to-point interfaces are now allowed
1026 - The main select(2) loop now uses a timeout
1027 - A small bugfix in the select fd-set update code
1028 - Some bugfixes in the configuration file parsing
1029 - stdout/stderr are now set to not be buffered
1030 - A bugfix in the MID generation regarding seq. numbering
1034 A new set of functions that are called whenever a change in the
1035 interface configuration(update, addition, removal) is made is
1037 These functions are added and removed very much like the ptf
1038 functions. Available trough the functions add_ifchgf and del_ifchgf.
1040 OBS OBS OBS!!! PLUGIN DEVELOPERS READ THIS!!!!
1042 The interface struct(declared in interfaces.h) has changed.
1043 Plugin developers must update plugins that uses the interface
1046 The headerfile olsr_plugin_io.h which contains the plugin interface
1047 commands now contains a revision list where all changes are
1051 0.4.5 ---------------------------------------------------------------------
1055 A plugin that generates and checks message signatures is added.
1058 PLUGIN: TOPOLOGY GRAPH
1060 A plugin that generates output of the topology in the dot format
1061 is added. See lib/dot_draw
1065 Some optimizations done that should cause fewer route recalculations.
1069 Some bugs reported by Takafumi Tanaka fixed.
1071 RESTORATION OF NETWORK SETTINGS
1073 Network settings like disabling of ICMP redirects and spoof filter, are
1074 now restored at exit by olsrd.
1078 Nodes would in certain scenarios retransmit messages originating for
1079 themselves. This was a RFC incompliance. Reported by Ingmar Baumgart.
1083 No longer setting the HELLO interval of non-wlan interfaces as a multiplier
1084 of the wlan interval. The interval is set seperatly now.
1085 Due to this there are some updates in the configfile imperatives.
1089 Some new macros introduced for table insertion and removal and IP
1090 copying and comparison.
1094 IPv6 bugfixes in the GUI.
1097 0.4.4 ---------------------------------------------------------------------
1101 Routes are no longer added via neighbors declaring a willingness
1104 LINK SENSING AND ROUTE CALCULATION
1106 Link sensing and route calculation has been updated to handle
1107 multiple links between hosts in a sane way.
1111 IP spoof filtering is disabled on the interfaces which olsrd runs.
1112 These settings are not restored!
1116 ICMP redirect message generation is disabled on the interfaces
1118 These settings are not restored!
1120 CONFIGFILE OPTIONS FOR MID AND HNA ADDED
1122 Options to set the MID and HNA emission intervals and
1123 validity time in the configfile added.
1127 Option to set what IPv6 address type(scope) to use in the
1128 configfile added. It can be set to either global or site-local.
1132 Options to set site-local and global multicast addresses
1133 in the configfile added.
1135 EMISSION INTERVAL FUNCTION
1137 Functions to set emission intervals at runtime added.
1139 LINK LAYER NOTIFICATIONS
1141 If started with the -llinfo switch olsrd will collect and display
1142 link-layer information on neighbors. This is no longer limited to
1143 one interface. But no action is taken based on this info - and
1144 there is a upper limit of 8 neighbors from which this info can
1145 be collected pr. interface. This limitation is inherited from the
1146 WLAN drivers and is not something imposed by the olsrd code!
1148 IPv6 HNA MESSAGE FORMAT
1150 IPv6 HNA messages now contains 128-bit netmask instead of prefix.
1154 Added "packet transform functions" which allow plugins to alter all
1155 outgoing OLSR traffic.
1159 Moved most headers out of OS dependent directories. The tunneling
1160 and link-layer notification interface is not yet separated from
1161 the /linux directory.
1165 A manpage(olsrd(8)) describing olsrd has been created. It is installed
1166 when using 'make install'.
1169 0.4.3 ---------------------------------------------------------------------
1173 Olsrd now supports runtime-loadable plugins! A couple of example plugins
1174 are located in the lib/ directory. Read the README files in the various
1175 plugin directories for more info. A directive to load plugins have been
1176 added to the configfile as well.
1177 Documentation of the plugin interface can be fount at http://www.olsr.org.
1179 The plugin interface is designed to be extendable. But it should _always_
1180 be backwards compatible with the interface used in this release!
1182 LINK-LAYER NOTIFICATION
1184 Some preliminary link-layer notification code has been added. Link quality
1185 can be written to stdout if olsrd is started with the -llinfo switch.
1186 No action is currently taken based on this info. And info will only
1187 be retrieved from the interface named "eth1".
1188 This code is not usable for users as of yet!
1192 Neighbors with willingness set to WILL_ALWAYS is now always added. The
1193 MPR selection is optimized as described in RFC3626 section 8.3.1
1198 There was a couple of bugs in the MPR selection code. All fixed.
1202 Users could not run olsrd on multiple interfaces using the Linux 2.6 kernel
1203 series. This is now fixed.
1207 One small bug in link hysteresis initialization and one in HNA route
1210 MESSAGE-SEQUENCENUMBER INCOMPLIANCE
1212 Message-seqnos was implemented on a pr. messagetype and pr. interface
1213 basis. This is not RFC3626 compliant and has been updates. All messages
1214 and interfaces now uses a global seuencenumber.
1216 RANDOM SEQUENCENUMBERS
1218 Sequencenumbers are now initialized using a random value.
1222 Fixes for running olsrd in daemon mode(debug 0).
1226 Optimizations based on profiling implemented.
1230 Message size is checked for every message before passing it to the
1231 appropriate message parsing function. If the size is bigger than the
1232 remaining size of the olsr packet then the message is discarded.
1236 Some minor modifications done to the gui.
1240 Lots of changes in handling of registration and unregistration of
1241 scheduler, socketparser, parser and local hna set.
1242 Some restructuring and movement of functions.
1245 0.4.2 ---------------------------------------------------------------------
1249 0.4.1 ---------------------------------------------------------------------
1253 0.4.0 ---------------------------------------------------------------------
1257 Link hysteresis as described in the RFC added.
1261 TC redundancy as described in the RFC added
1265 MPR redundancy as described in the RFC added
1269 The scheduler has been rewritten to register scheduled
1270 events(function pointers) dynamically.
1274 The parser has been rewritten to register parse functions
1275 on a pr. messagetype dynamically
1279 A wrapper for the malloc(3) syscal has been introduced.
1280 olsr_malloc(size_t, const char *) should ALWAYS be used.
1284 Lots of restructuring in headerfiles.
1285 Linux spesific code moved to subdirectory linux/
1286 FreeBSD code to be put in freebsd/
1287 LOTS of code restructured due to the rexrite of the scheduler
1292 Optimizing the MPR set as suggested in the RFC section
1293 8.3.1 point 5 added.
1297 Some bugs in MPR selection fixed.
1300 0.3.8 ---------------------------------------------------------------------
1304 HNA code completely rewritten!
1305 The old code was really bad! Now it is much cleaner implemented and
1307 One- and two-hop neighbor list structures rewritten. They now use
1308 the same hashed double-linked lists as the rest of the information
1313 Some code restructuring which resulted in the new files: timer.h,
1314 mantissa.c, mantissa.h, hashing.c, hashing.h, linux/net.c
1315 linux/net.h, linux/kernel_routes.c, linux/kernel_routes.h and some
1320 The bug causing errormessages on exit is fixed.
1321 The bug that caused initial HNA routes in the GUI to display a hopcount
1323 IPv6 HNA netmasks were all added as /128. It's fixed now.
1327 Turns out sitelocal address had to be preferred to avoid IPv6 header
1328 messing up link-sensing. Bug fixed
1331 0.3.7 ---------------------------------------------------------------------
1335 The entire TC set and MPR selector set code rewritten. Hashing and
1336 double linked lists added to the MID code.
1337 Lots of HNA code has been rewritten as well.
1341 When a node lost connectivity to a HNA GW all HNA entries to that gw
1342 was deleted. This has been fixed - and HNA entries only gets deleted
1344 Other HNA bugs have been fixed as well. But the whole HNA implementation
1349 There was a bug that caused holdingtime not to be properly recalculated
1350 when using non-default emission intervals.
1352 Forwarding and symmetric neighbors
1354 Seems I had misread the RFC on what a 1-hop symmetric neighbor is.
1355 Now the link-set is checked when a check for a symmetric neighbor
1356 is done. Not the 1 hop neighbor set as it used to be. This way
1357 the hack when receiving MID messages could be removed.
1361 Global addresses are now preferred. Sitelocal addresses are only used
1362 if no global addresses are found. There have been problems where
1363 the address set in the IP header of IPv6 packets do not match the
1364 address chosen by OLSR.
1368 The GUI is finally updated! It can now handle piggybacked messages
1369 and link sensing HELLO message format.
1372 0.3.6 ---------------------------------------------------------------------
1374 HNA support using IPv6
1376 HNA now works using IPv6 as well! Just add the network address and
1377 prefix in the HNA6 section in the configfile. The IPv6 HNA packets differ
1378 some from the IPv4 as they don't send the netmask but the prefix.
1381 NEW FILENAME FOR THE BINARY AND CONFIG FILE
1383 They are now called olsrd and olsrd.conf. I figured I'd use the olsrd
1384 name before somebody else started using it ;-)
1389 New options: DEBUG, HNA6 and IPC-CONNECT added to config file.
1394 A printf-wrapper has been introduced - debug level output handling
1395 is much more uniform now.
1396 The daemon should run fine in detached mode now(DEBUG 0)
1400 The GUI front-end can now connect and disconnect at any time while the
1401 daemon is running, if started using the -ipc switch or with IPC set to
1402 'yes' in the configfile.
1407 A small HNA bug fixed.
1410 0.3.5 ---------------------------------------------------------------------
1414 Forwarding jitter added. Messages are piggybacked if they arrive(and are to
1415 be forwarded) while there is data to be forwarded buffered.
1416 Added some bugfixes to support parsing of piggybacked messages as well.
1420 Fixed route calculation so that 2 hop neighbors are added. This smooths
1421 changes from 1 hop to 2 hop neighbor out. The old way one had to wait for
1422 a TC before the 2 hop neighbors were added.
1426 All neighbors received in HELLO messages are added to the two hop
1427 neighborhood. This helps smoothing out the 1-to-2 hop transition as well.
1431 MID calculation had to be updated due to the registering of two hop neighbors
1432 that are already one hop neighbors. They should not be considered when calculating
1437 Deletion of possible one hop neighbors registered on non main-addresses when
1438 first registering MID info from a node removed. This can not occur due
1439 to the fact that registering of neighbor nodes are done on main addresses
1441 Option to not forward messages on wired links on which they arrived removed.
1442 This is no longer usable to any degree when adding support for piggybacking
1443 of forwarded messages is to be implemented.
1447 Some unused parameters and commandline options were removed.
1451 0.3.3 ---------------------------------------------------------------------
1455 Added sending of empty TC messages if all MPR selectors are removed. Empty
1456 TC messages are sent for a TC_HOLD_TIME period as described in section
1461 Fixed HNA route calculations for IPv6. I forgot to upgrade this in 0.3.2
1465 -hnaint and -midint command line optionas added to set the interval
1466 of HNA and MID generation.
1470 As an optimization messages have not been forwarded on the received interface
1471 if this is registered as a non-WLAN interface. This causes problems for
1472 people using Ethernet-to-WLAN adapters. This optimization is now turned
1473 off by default. It can be activated using the -nofwlan option.
1477 THERE ARE SOME NASTY BUGS IN 0.3.2!
1478 Fixed a bug that caused 2 hop neighbors not to time out.
1479 Fixed a bug that caused a 1 hop neighbor timeout not to recalculate
1481 Fixed a small memleak in the MID set
1482 Fixed some smaller bugs.
1484 IPv6 functioning is not well tested in this release.
1486 0.3.2 ---------------------------------------------------------------------
1490 Updated HNA to be RFC compliant. This means that all received HNA tuples
1491 are registered and only the subset of unique entries(net/netmask) with
1492 the smallest hopcount is inserted into the routing table.
1496 User can specify configfile name using the -f switch.
1500 Fixed a link-sensing bug that caused problems when using MID nodes.
1502 0.3.1 ---------------------------------------------------------------------
1506 MPR calculation is now based on the willingness announced by nodes.
1510 The neighbor set does not have timeouts on entries any more. Creation
1511 and deletion of neighbor entries is done from the link-set as suggested
1516 Gotten rid of a lot of code that became more or less obsolete due to
1517 all the changes introduced in 0.3.0.
1521 Fixed a nasty bug concerning the sequence numbering of TC packets.
1522 Fixed some bugs regarding MPR calculation - and probably introduced
1523 a whole new species when implementing the willingness-based calculation ;-)
1526 0.3.0 ---------------------------------------------------------------------
1528 Due to the extensive amount of updates this release is versioned 0.3.0
1530 Duplicate table and forwarding
1532 The duplicate table functionality is totally rewritten in 100% RFC
1533 compliance. The forward algorithm specified in the RFC is implemented
1534 this meant rewriting much of the packet processing code. The daemon
1535 also forwards unknown packettypes now.
1537 Link sensing and neighbor processing
1539 Link sensing and neighbor processing was done in the same operation in the
1540 old code. Link sensing is now a mechanism of its own which is 100% RFC
1541 compliant. Neighbor processing and HELLO generation has been partly
1542 rewritten to be RFC compliant. Neighbors are now registered as either
1543 SYN or NOT_SYM. The NOT_NEIGH, SYM_NEIGH and MPR_NEIGH values are only
1544 used when building HELLO messages. Links are in one of the following states:
1545 UNSPEC_LINK, ASYM_LINK or SYM_LINK.
1546 HELLO messages now advertise link status of neighbors on the interface
1547 the message is transmitted.
1551 A node now dynamically calculates willingness based on powersource and
1552 possibly battery power. If the node is AC powered it announces a willingness
1553 of 6. If batterypowered the willingness is calculated as:
1555 Where P is percentage of power left.
1559 The daemon now tries to read its configuration from the file /etc/uolsrd.conf
1560 A "standard" configuration file is installed when doing 'make install'.
1561 This file should be edited to fit your needs.
1562 Command-line options can still be used to override the configuration form
1563 the file(ore if no config file is present).
1564 The -f switch can also be used to specify a configuration file.
1568 If AdvancedPowerManagemant(APM) is supported on your system the willingness
1569 of the node is dynamically calculated based upon the powerstatus of the node.
1570 MPR calculation based upon willingness is not done as of yet.
1574 A bugs in the TC processing fixed.
1578 Some serious HNA bugs fixed. These bugs caused a node to always choos the
1579 gateway with the larges hopcout :) More seriously - a bug caused looping
1580 of HNA messages in certain scenarios.
1582 Package sequence numbers
1584 These were added. Not much use as of now - but they're there(as specified
1589 Users can now specify the broadcast address to use. Useful if one wishes to
1590 use the 255.255.255.255 broadcast.
1594 0.2.5 ---------------------------------------------------------------------
1598 Htime and Vtime processing and handling added. Holding times used to be
1599 a static value for all nodes. Now every node can signal its vlidity time
1601 To achieve this mantissa/exponent calculation functionality was added.
1602 Messages now include Vtime(and Htime in HELLO) values in mantissa/exponent
1603 format instead of just zero. These values are as stated above, used as holding
1605 the GUI should be upgraded as well...
1609 The use of jitter in message generation intervals vere fixed.
1612 0.2.4 ---------------------------------------------------------------------
1616 Some bugs concerning sequence numbers in HELLO and MID message handling
1617 was fixed. Newly registered nodes in the neighbor and MID sets were
1618 initialized with a seqno of 0. When using a "wraparound" sequencenumber
1619 check(as defined in olsr_protocol.h) this can produce errors if a new
1620 node joins a network where existing nodes has seqnos >0x00FF.
1624 Some checks and copying of node addresses where done using sizeof(u_olsr32_t)
1625 which is 32 bits. This caused only the 32 firs bits of IPv6 addresses to
1626 be copied and checked.
